Description

Component mounting machine, tape feeder, tape placement unit

Technical Field

The present invention relates to a technique for feeding components accommodated in a component feeding tape by a tape feeder.

Background

Conventionally, a tape feeder that intermittently feeds a component supply tape accommodating a plurality of components arranged at a predetermined pitch to a component supply position by the pitch is used for mounting components on a substrate. Patent documents 1 and 2 disclose a tape feeder capable of simultaneously mounting two component feeding tapes.

For example, the tape feeder of patent document 1 supplies one component supply tape contained in two component supply tapes while making the other component supply tape stand by. Specifically, the tape placement portion is capable of being inserted into and removed from the rear end portion of the main body of the tape feeder, and the tape placement portion holding the other component supply tape is inserted into the main body of the tape feeder, whereby the other component supply tape can be put on standby.

When one component feeding tape component is used up, the tape feeder starts feeding another component feeding tape component. Then, the operator pulls out the tape placement portion from the main body of the tape feeder, further holds the other component supply tape to the tape placement portion, and then inserts the tape placement portion into the main body of the tape feeder. Thereby, the other tape feeder can be made standby.

Problems to be solved by the invention

However, in patent document 1, when mounting the component supply tape on the tape feeder, it is necessary to perform an operation of pulling out the tape placement portion from the main body of the tape feeder and then inserting the tape placement portion into the main body of the tape feeder. Accordingly, there is a need for a technique that can easily mount the component supply tape to the tape feeder without requiring such a complicated operation.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a technique that can easily mount a component supply tape on a tape feeder.

Means for solving the problems

The component mounting machine according to the present invention includes: a tape feeder is provided with: a feeder main body having a feeder engaging portion configured to be engageable with a unit engaging portion of a tape placement unit that holds a component supply tape that accommodates components; and a tape conveying section that supplies the component to the component supply position by driving the component supply tape; and a mounting head for mounting components supplied from the tape feeder to the component supply position on the substrate, wherein the unit engagement portion is configured to be capable of entering an engagement position with the feeder engagement portion and being capable of exiting from the engagement position, the unit engagement portion enters the engagement position and the unit engagement portion is engaged with the feeder engagement portion, whereby the tape placement unit is mounted on the feeder body, the unit engagement portion exits from the engagement position and the engagement of the unit engagement portion with the feeder engagement portion is released, and the tape placement unit is disengaged from the feeder body.

The tape feeder according to the present invention includes: a feeder main body having a feeder engaging portion configured to be engageable with a unit engaging portion of a tape placement unit that holds a component supply tape that accommodates components; and a tape conveying section configured to supply the component to the component supply position by driving the component supply tape, the unit engaging section being configured to be able to enter an engaging position with which the feeder engaging section is engaged, and to be able to exit from the engaging position, the unit engaging section entering the engaging position and the unit engaging section being engaged with the feeder engaging section, whereby the tape placing unit is mounted to the feeder main body, the unit engaging section exiting from the engaging position and the unit engaging section being disengaged from the feeder engaging section, whereby the tape placing unit is disengaged from the feeder main body.

The tape placement unit according to the present invention includes: a tape holding unit for holding a component supply tape for accommodating components; and a unit engaging portion having a shape capable of engaging with a feeder engaging portion of a feeder main body provided in the tape feeder, the unit engaging portion being configured to be capable of entering an engaging position with the feeder engaging portion and being capable of exiting from the engaging position, the unit engaging portion entering the engaging position and the unit engaging portion being engaged with the feeder engaging portion, whereby the tape holding portion is attached to the feeder main body, the unit engaging portion exiting from the engaging position and the engagement of the unit engaging portion with the feeder engaging portion being released, whereby the tape holding portion is disengaged from the feeder main body.

According to the present invention (component mounter, tape feeder, tape placement unit) configured as described above, the tape placement unit that holds the component supply tape that accommodates the components is mounted to the feeder body of the tape feeder. The tape placement unit includes a unit engagement portion having a shape that can be engaged with a feeder engagement portion of a feeder main body of the tape feeder. The unit engaging portion is configured to be able to enter an engaging position with which the feeder engaging portion engages, and to be able to withdraw from the engaging position. Therefore, the unit engaging portion enters the engaging position and the unit engaging portion engages with the feeder engaging portion, whereby the tape placing unit is held by the feeder main body, and the unit engaging portion is withdrawn from the engaging position and the engagement of the unit engaging portion with the feeder engaging portion is released, whereby the tape placing unit is disengaged from the feeder main body. According to this configuration, if the operator prepares a subsequent tape placement unit holding the component supply tape in addition to, for example, the preceding tape placement unit attached to the feeder main body, the subsequent tape placement unit can be attached to the feeder main body while the preceding tape placement unit is detached from the feeder main body. In this way, the component supply tape can be easily mounted on the tape feeder.

In addition, the component mounting mechanism may be configured to: the unit engaging portion is configured to be capable of entering the engaging position from one side and being capable of exiting from the engaging position to the other side opposite to the one side, the unit engaging portion enters the engaging position from one side and the unit engaging portion engages with the feeder engaging portion, whereby the tape placing unit is mounted to the feeder main body, the unit engaging portion exits from the engaging position to the other side and the engagement of the unit engaging portion with the feeder engaging portion is released, whereby the tape placing unit is disengaged from the feeder main body.

In this configuration, the unit engaging portion is configured to be able to enter an engaging position with which the feeder engaging portion is engaged from one side, and to be able to withdraw from the engaging position to the other side opposite to the one side. Therefore, the unit engaging portion enters the engaging position from one side and the unit engaging portion engages with the feeder engaging portion, whereby the tape placing unit is held by the feeder main body, the unit engaging portion withdraws from the engaging position to the other side, and the engagement of the unit engaging portion with the feeder engaging portion is released, whereby the tape placing unit is disengaged from the feeder main body. Therefore, if the operator prepares a subsequent tape placement unit holding the component supply tape in addition to, for example, the preceding tape placement unit attached to the feeder main body, the subsequent tape placement unit can be attached to the feeder main body from one side while the preceding tape placement unit is detached from the feeder main body to the other side. In this way, the component supply tape can be easily mounted on the tape feeder.

In addition, the component mounting mechanism may be configured to: one of the unit engaging portion and the feeder engaging portion has a flange extending from one side to the other side, the other engaging portion has a groove extending from one side to the other side, both ends of the groove have openings at one side and the other side, respectively, the flange is inserted into the groove through the opening as the unit engaging portion is brought into the engaging position, whereby the flange is engaged with the groove and the tape placing unit is mounted to the feeder main body, and the flange is pulled out of the groove through the opening as the unit engaging portion is withdrawn from the engaging position, whereby the engagement of the flange with the groove is released and the tape placing unit is disengaged from the feeder main body. With this configuration, the tape can be easily fed to the tape feeder mounting member as follows.

That is, in the case where the unit engagement portion has a flange and the feeder engagement portion has a groove, the flange of one tape placement unit may be fitted into the groove of the feeder body from one side while the flange of the other tape placement unit is separated from the groove of the feeder body to the other side. Thereby, the other tape placement unit can be attached to the feeder main body and the component supply tape can be attached to the tape feeder.

Alternatively, in the case where the unit engagement portion has a groove and the feeder engagement portion has a flange, the groove of one tape placement unit may be fitted into the flange of the feeder body from one side while the groove of the other tape placement unit is separated from the flange of the feeder body to the other side. Thereby, the other tape placement unit can be attached to the feeder main body and the component supply tape can be attached to the tape feeder.

In addition, the component mounting mechanism may be configured to: the tape placement unit has: a tape mounting member for mounting the component supply tape; a lever having a tape restraining member that can be moved in and out with respect to the component supply tape on the tape mounting member; a biasing member for biasing the tape regulating member in a direction away from the component supply tape on the tape mounting member; and an engaging member that is movable between a restricting position where the lever is engaged with the engaging member and a releasing position where the lever is disengaged from the engaging member, wherein the engaging member is engaged with the lever located at the restricting position to restrict movement of the tape restricting member against the urging force of the urging member, and wherein the lever is moved from the releasing position to the restricting position after the tape restricting member is brought into contact with the component supply tape by bringing the tape restricting member into proximity with the component supply tape on the tape mounting member against the urging force, whereby the tape restricting state of the component supply tape is maintained, and wherein the lever is pushed out by the feeder main body toward the releasing position to disengage from the engaging member when the unit engaging portion of the tape placing unit that maintains the tape restricting state is brought into the engaging position from one side, whereby the tape restricting state is released.

According to this configuration, the tape restraining member provided in the lever is brought into contact with the component supply tape, and then the lever is moved from the release position to the restraining position and engaged with the locking member, whereby the tape restraining state of the component supply tape can be maintained. Therefore, the tape can be prevented from coming off the tape placement unit by the tape restraining state before the tape placement unit is mounted to the feeder main body. When the unit engaging portion of the tape holding unit that maintains the tape restraining state is brought into the engaging position from one side, the lever is pushed out by the feeder main body to the release position and is disengaged from the engaging member, whereby the tape restraining state is released. Therefore, after the tape placement unit is attached to the feeder main body, the component feeding tape held by the tape placement unit can be conveyed and the component housed in the component feeding tape can be fed to the component feeding position.

In addition, the component mounting mechanism may be configured to: in this case, the first tape placing unit is pushed out by the second tape placing unit, the unit engaging portion of the first tape placing unit is withdrawn from the engaging position, the first tape placing unit is separated from the feeder main body, and the unit engaging portion of the second tape placing unit is brought into the engaging position, whereby the second tape placing unit is attached to the feeder main body. In this configuration, the preceding tape placing unit (first tape placing unit) is pushed out by the following tape placing unit (second tape placing unit), whereby the following tape placing unit can be attached to the feeder main body while the preceding tape placing unit is detached from the feeder main body. In this way, the component supply tape can be easily mounted on the tape feeder.

In addition, the component mounting mechanism may be configured to: the tape feeder is provided with a carriage to which the second tape placement unit is detachably attached, and the carriage is moved from one side toward the tape feeder, whereby the second tape placement unit is attached to the feeder body while the first tape placement unit is detached from the feeder body by the second tape placement unit attached to the carriage, whereby the unit replacement can be performed. In this configuration, by moving the carriage on which the subsequent tape placement unit is mounted toward the tape feeder, the subsequent tape placement unit can be mounted to the feeder body while the preceding tape placement unit is pushed out by the subsequent tape placement unit and detached from the feeder body. In this way, the component supply tape can be easily mounted on the tape feeder.

In addition, the component mounting mechanism may be configured to: the feeder is also provided with an unmanned conveyor that performs unit replacement by moving the carriage from one side toward the tape feeder. In this configuration, the component supply tape can be mounted on the tape feeder without requiring manual work by an operator.

In addition, the component mounting mechanism may be configured to: the carriage has a locking mechanism, and when the second tape placing unit is locked by the locking mechanism, the removal of the second tape placing unit from the carriage is prohibited, and when the locking of the second tape placing unit by the locking mechanism is released, the removal of the second tape placing unit from the carriage is permitted. In this structure, the tape placing unit can be prevented from falling off the carriage by the locking mechanism before the tape placing unit is attached to the feeder main body. Further, after the tape placing unit is attached to the feeder main body, the carriage can be separated from the feeder main body while leaving the tape placing unit in the feeder main body by releasing the lock.

In addition, the component mounting mechanism may be configured to: the tape placing unit has a unit identifier for identifying the tape placing unit, and the tape feeder further has a reading portion that reads the identifier of the tape placing unit attached to the feeder main body. In this configuration, the tape placing unit attached to the feeder main body can be identified based on the identifier read by the reading section.

In addition, the component mounting mechanism may be configured to: the tape feeder further includes a control unit that determines whether or not a combination of the tape feeder and a tape placement unit attached to the tape feeder is appropriate based on the identifier read by the reading unit of the tape feeder. In this configuration, it is possible to grasp whether or not the combination of the tape placement unit attached to (the feeder body of) the tape feeder and the tape feeder is appropriate.

In addition, the component mounting mechanism may be configured to: the control unit is further provided with a notification unit for notifying the operator of the combination failure, and the control unit notifies the operator of the error by the notification unit when the combination failure is determined. In this configuration, when the combination of the tape feeder and the tape placement unit is not appropriate, the operator can quickly perform the necessary work.

In addition, the component mounting mechanism may be configured to: the tape feeder further includes a unit pressing portion that separates the tape placement unit from the feeder main body by pressing the tape placement unit attached to the feeder main body to withdraw the unit engaging portion of the tape placement unit from the engaging position. In this configuration, the tape placement unit can be detached from the feeder main body without requiring manual work by an operator.

The component mounting mechanism may be configured to: the feeder main body also has a supporting portion that supports the tape placing unit mounted to the feeder main body. In this structure, the tape placing unit attached to the feeder main body can be firmly supported by the supporting portion.

Detailed Description

Fig. 1 is a plan view schematically showing an example of a component mounter according to the present invention. Fig. 1 shows an XYZ rectangular coordinate system composed of a Z direction parallel to the vertical direction, and X and Y directions parallel to the horizontal direction. The component mounter 1 includes a pair of conveyors 12, 12 provided on a base 11. The component mounter 1 mounts components on a substrate B carried in from the upstream side in the X direction (substrate conveying direction) to a work position (position of the substrate B in fig. 1) by the conveyor 12, and carries out the substrate B after the component mounting from the work position to the downstream side in the X direction by the conveyor 12.

The component mounter 1 is provided with a pair of Y-axis rails 21, 21 extending in the Y-direction, a Y-axis ball screw 22 extending in the Y-direction, and a Y-axis motor My that rotationally drives the Y-axis ball screw 22, and a nut fixed to the Y-axis ball screw 22 in a state of being supported by the pair of Y-axis rails 21, 21 so as to be movable in the Y-direction. The head support member 23 is mounted with an X-axis ball screw 24 extending in the X-direction and an X-axis motor Mx for rotationally driving the X-axis ball screw 24, and the head unit 3 is fixed to a nut of the X-axis ball screw 24 in a state of being supported by the head support member 23 so as to be movable in the X-direction. Therefore, the head unit 3 can be moved in the Y direction by rotating the Y-axis ball screw 22 by the Y-axis motor My, or the head unit 3 can be moved in the X direction by rotating the X-axis ball screw 24 by the X-axis motor Mx.

Two component supply units 25 are arranged in the X direction on both sides of the pair of conveyors 12, 12 in the Y direction, and a plurality of tape feeders 4 are arranged in the X direction in each component supply unit 25. Each tape feeder 4 has a component feeding position 40 at a front end portion on the conveyor 12 side, and supplies components stored in a component feeding tape TP (fig. 2 and 3) to the component feeding position 40. The component supply tape TP accommodates components in each of a plurality of pockets arranged in a row at equal intervals, and the tape feeder 4 intermittently feeds the component supply tape TP in the Y direction at the intervals, thereby supplying the components to the component supply position 40. The component accommodated in the component supply tape TP is, for example, a chip-like electronic component such as an integrated circuit, a transistor, or a capacitor.

The head unit 3 has a plurality of (4) mounting heads 31 arrayed in the X direction. Each mounting head 31 has a long shape extending in the Z direction (vertical direction), and can suck and hold a component by a suction nozzle detachably mounted at the lower end thereof. That is, the mounting head 31 moves upward of the tape feeder 4, and adsorbs the components supplied from the tape feeder 4 to the component supply position 40. Next, the mounting head 31 moves upward of the substrate B in the working position to release the suction of the component, thereby mounting the component on the substrate B. In this way, the mounting head 31 performs component mounting that suctions components supplied to the component supply position 40 by the tape feeder 4 and mounts the components onto the substrate B.

Fig. 2 is a side view schematically showing an example of the structure and operation of the tape feeder. In this drawing and the following drawings, the feeding direction Df (parallel to the Y direction) in which the component feeding tape TP is fed out by the tape feeder 4 is appropriately shown, and the arrow side of the feeding direction Df is treated as "front" of the feeding direction Df, and the opposite side of the arrow of the feeding direction Df is treated as "rear" of the feeding direction Df. That is, the conveyance direction of the component supply tape TP corresponds to the front side (the other side), and the opposite side to the conveyance direction corresponds to the rear side (the one side). In order to distinguish between two component supply tapes TP that can be mounted on the tape feeder 4, different reference numerals TP1 and TP2 are appropriately used for the carrier tapes in this drawing and the following drawings.

The tape feeder 4 includes a feeder body 41 as a mechanical structure and motors Mf and Mb for driving the feeder body 41. The feeder main body 41 has a flat-shaped case 42 that is thin in the X direction and long in the feeding direction Df. The tape insertion port 43a (indicated by a broken line) extending in the Z direction is opened at the rear end of the housing 42 in the feeding direction Df, and the above-described component supply position 40 is provided on the front upper surface of the housing 42 in the feeding direction Df. The tape feeding path 43b from the tape insertion port 43a to the component feeding position 40 is provided in the feeder main body 41. The feeder body 41 receives the driving force of the motors Mf, mb and feeds the component supply tape TP inserted from the tape insertion port 43a to the tape conveying path 43b in the feeding direction Df, thereby supplying the components to the component supply position 40.

Specifically, the feeder main body 41 includes, in the case 42, a sprocket 44 disposed adjacent to the tape insertion port 43a above the tape conveying path 43b, and a gear 45 for transmitting the driving force of the motor Mb to the sprocket 44, and the sprocket 44 is rotated by the driving force of the motor Mb. The feeder main body 41 further includes a bracket 411 that can be engaged with the tape placement unit 5. The tray 411 is provided at a rear end portion of the feeder main body 41 so as to extend in the feeding direction Df and protrude rearward, and a lower side of the tray 411 serves as an arrangement space for the tape placing unit 5 engaged with the tray 411. The tape placing unit 5 engaged with the bracket 411 is opposed to the sprocket 44 from below, and the component supply tape TP is engaged with the sprocket 44 by sandwiching the component supply tape TP between the tape placing unit 5 and the sprocket 44. Thus, the sprocket 44 rotates while engaging with the component tape TP, and thereby the component tape TP can be fed in the feeding direction Df. The feeder main body 41 includes a sprocket 47 disposed at a front end portion thereof and adjacent to the tape conveying path 43b from below, and a gear 48 for transmitting a driving force of the motor Mf to the sprocket 47, in the case 42, and the sprocket 47 is rotated by the driving force of the motor Mf. Therefore, the sprocket 47 intermittently rotates while engaging with the component tape TP, and thereby intermittently conveys the component tape TP in the feeding direction Df.

The feeder body 41 has a cutter that contacts the component tape TP on the upstream side in the feeding direction Df of the component feeding position 40. The cutter cuts the cover tape of the component supply tape TP intermittently fed in the feeding direction Df at the center and winds up the cover tape on both sides, thereby exposing the components supplied to the component supply position 40. The structure for exposing the element in this way is the same as that described in, for example, japanese patent application laid-open No. 2015-053320. However, the specific structure of exposing the element is not limited to this example. That is, the adhesive portions to which the cover tape is adhered are provided on both sides in the width direction (direction orthogonal to the longitudinal direction) of the component supply tape TP so as to sandwich the component housing portions (pockets). The components may also be exposed by peeling one of the adhesive portions while the other adhesive portion remains, and rolling up the cover tape.

Step S11 corresponds to a state in which the component supply tape TP1 is used for component mounting by the mounting head 31. That is, the component supply tape TP1 is inserted into the feeder main body 41 along the tape conveying path 43B, and the sprocket 47 intermittently conveys the component supply tape TP1 in the feeding direction Df, thereby supplying the component to be mounted on the substrate B to the component supply position 40. Further, in step S11, the front end of the component supply tape TP2 for component mounting following the component supply tape TP1 is mounted between the sprocket 44 and the tape placing unit 5. In this way, the component supply tape TP2 to be used next stands by at the rear end portion of the feeder main body 41.

As shown in step S12, when the component in the component supply tape TP1 is exhausted and the tape feeder 4 discharges the component supply tape TP1, the loading shown in step S13 is performed. Specifically, the sprocket 44 starts to rotate, and the component tape TP2 is fed out in the feeding direction Df toward the component feeding position 40, so that the tip end of the component tape TP2 engages with the sprocket 47. Next, in step S14, for example, when the operator removes the tape placing unit 5 from the housing 42, the component supply tape TP2 is separated from the sprocket 44 and falls down toward the tape conveying path 43 b. Thus, the sprocket 47 can intermittently feed the component feeding tape TP2 in the feeding direction Df and feed the components in the component feeding tape TP2 to the component feeding position 40. Incidentally, intermittent conveyance of the component supply tape TP may be performed in a state where the tape placing unit 5 is mounted to the housing 42. Specifically, the sprocket 44 may be provided with a one-way clutch that rotates in response to movement of the component supply tape TP to the front side in the feeding direction Df when the motor Mb is stopped, and that restricts movement of the component supply tape TP to the rear side in the feeding direction Df.

Fig. 3 is a diagram schematically showing a relationship between the component supply reel holding the component supply tape and the tape feeder. The component supply reel 6 has an axial center 61 and two side plates 62 sandwiching the axial center 61 from both sides, and supports the component supply tape TP wound around the axial center 61 from both sides via the side plates 62. The component supply reel 6 has a reel ID63 and a component ID64 each formed of a bar code on the side plate 62. The reel ID63 is unique and can be used to individually identify the component supply reel 6 to which the reel ID63 is attached. The component ID64 indicates information (type, number, etc. of components) related to the components stored in the component supply tape TP of the component supply reel 6 to which the component ID64 is attached. The reel ID63 and the component ID64 are not necessarily constituted by separate bar codes, and may be constituted by one bar code.

In this way, the two component supply reels 6 are disposed with respect to the one tape feeder 4, and the two component supply tapes TP pulled out from the two component supply reels 6 can be attached to the one tape feeder 4. Of these two component supply reels 6, one component supply reel 6 is held at a lower holding position Ll, and the other component supply reel 6 is held at an upper holding position Lu above the lower holding position Ll.

In contrast, the component mounter 1 includes: a feeder mount carriage 7 that holds the component supply reel 6 at a lower holding position Ll; and a component replenishment carriage 8 that holds the component supply reel 6 at the upper holding position Lu. The specific structures of the feeder shoe 7 and the component replenishment shoe 8 will be described later, and these are schematically and simplified in fig. 3. The feeder mount carriage 7 and the component replenishment carriage 8 are detachably mounted to the component supply section 25. As described later, the tape feeder 4 is detachably mounted to the feeder mount carriage 7, and the feeder mount carriage 7 functions to hold the tape feeder 4 in addition to the function of holding the component supply reel 6. The feeder mount carriage 7 is mainly used for preparation work for disposing the tape feeder 4 and the component supply reel 6 in the component supply section 25, and the component replenishment carriage 8 is mainly used for replenishment work for replenishing the component supply reel 6 to the component supply section 25.

Fig. 4 and 5 are right rear perspective views of the feeder shoe and the component replenishment carriage, as viewed from the right obliquely rear, and fig. 6 is a left rear perspective view of the feeder shoe and the component replenishment carriage, as viewed from the left obliquely rear.

The feeder mount carriage 7 has two engagement protrusions 719a, 719b arranged parallel to the feeding direction Df on the inner side of the side plate 717. These engagement projections 719a, 719b protrude inward from the inner wall of the side plate 717 (i.e., toward the space sandwiched by the two side plates 717 in the X direction). The engagement protrusion 719a is disposed further to the rear than the engagement protrusion 719b in the feeding direction Df.

The feeder mount carriage 7 has a feeder mount portion 73 disposed between two side plates 717 and above a support plate 718, and the feeder mount portion 73 is supported by the two side plates 717 and the support plate 718. In the feeder mounting portion 73, a plurality of feeder slots 731 (feeder mounting positions) are arranged in the X direction, and the tape feeders 4 can be detachably mounted in the respective feeder slots 731.

The feeder mount carriage 7 further includes a reel holding portion 75 disposed between the two side wall plates 712 and above the bottom plate 711, and the reel holding portion 75 is supported by the two side wall plates 712.

Each of the reel holders 751 holds the mounted component supply reel 6 at the lower holding position Ll (fig. 3).

In the feeder mount carriage 7, a plurality of reel holders 751 are provided corresponding to the plurality of feeder slots 731, respectively. That is, the component supply tape TP pulled out from the component supply reel 6 held by one reel holder 751 is mounted on the tape feeder 4, and the tape feeder 4 is mounted to the feeder slot 731 corresponding to the one reel holder 751.

The feeder mount carriage 7 has a discard box 77 placed on the upper surface of the bottom plate 711 below the feeder mount section 73 and the reel holding section 75. The component supply tape TP discharged from the tape feeder 4 is discarded to the discard box 77.

The component replenishment carriage 8 has a bottom plate 811 and an insertion plate 812 each arranged horizontally. The bottom plate 811 has a peripheral edge formed of two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and is rectangular extending in the X direction in a plan view. The insertion plate 812 has a peripheral edge formed of two sides parallel to the X direction and two sides parallel to the feeding direction Df (Y direction), and has a rectangular shape extending in the feeding direction Df in a plan view. The insertion plate 812 is attached to the bottom plate 811 so as to protrude from the center of the bottom plate 811 in the X direction toward the front side in the feeding direction Df.

The component replenishment carriage 8 has two side wall plates 813 erected perpendicularly from both ends of the bottom plate 811 in the X direction. Each side wall plate 813 is attached to the bottom plate 811 in parallel with the feeding direction Df and the Z direction. The component replenishment carriage 8 further includes a beam 814 extending in the X direction between the two side wall plates 813. The beam 814 is erected between the upper ends of the side wall plates 813 at the rear ends of the side wall plates 813.

The component replenishment carriage 8 further includes: casters 815 mounted on both ends of the bottom plate 811 in the X direction; and casters 815 attached to both sides in the X direction at the front end of the insertion plate 812 in the feeding direction Df, and these casters 815 support the bottom plate 811 and the insertion plate 812 on the ground. Therefore, the component replenishment carriage 8 can move the casters 815 while rotating according to an external force from an operator, an unmanned carrier, or the like. In particular, the beam 814 functions as a handle, and the operator can move the component replenishment carriage 8 by operating the beam 814.

The component replenishment carriage 8 has two side plates 816 attached to the upper ends of the two side wall plates 813, respectively. Each side plate 816 protrudes from the side wall plate 813 toward the front side in the feeding direction Df. A slit 817 extending parallel to the feeding direction Df is provided at the front end of each side plate 816. The slits 817 are opened forward in the feeding direction Df and are arranged at the same height as the engaging protrusions 719a, 719b of the feeder shoe 7.

The component replenishment carriage 8 has a unit mounting portion 83 arranged so as to be sandwiched between two side plates 816, and the unit mounting portion 83 is supported by the two side plates 816. In the unit mounting portion 83, a plurality of unit slots 831 (unit mounting positions) are arranged in the X direction, and the tape placement unit 5 can be detachably mounted to each of the unit slots 831. The plurality of unit slots 831 are provided corresponding to the plurality of feeder slots 731 in the feeder mount carriage 7, respectively.

As described below, the component replenishment carriage 8 is detachably attached to the feeder attachment carriage 7, and the reel mounting table 85 holds the component supply reel 6 mounted on the mounting plate 853 at the upper holding position Lu (fig. 3) in a state where the component replenishment carriage 8 is attached to the feeder attachment carriage 7.

Fig. 7 to 10 are diagrams showing the mounting operation of the component replenishment carriage on the feeder mounting carriage. In particular, fig. 7 is a side view showing a state before the component replenishment carriage 8 is mounted away from the feeder-mounting carriage 7, fig. 8 is a side view showing a state after the component replenishment carriage is mounted on the feeder-mounting carriage, fig. 9 is a bottom view showing a state after the component replenishment carriage is mounted on the feeder-mounting carriage, and fig. 10 is a perspective view showing a state after the component replenishment carriage is mounted on the feeder-mounting carriage.

The component replenishment carriage 8 is moved toward the feeder attachment carriage 7 from a state (state shown in fig. 4 to 7) in which the two side plates 816 face the inner sides of the two side plates 717 of the feeder attachment carriage 7 in the X direction as viewed from the feeding direction Df. As shown in fig. 7 to 8, the operation of the component replenishment carriage 8 up to the feeder attachment carriage 7 is as follows.

Each side plate 816 of the component replenishment carriage 8 is located above the reel holding portion 75, and as the component replenishment carriage 8 moves toward the feeder attachment carriage 7, each side plate 816 passes above the reel holding portion 75 (and the component supply reel 6 held by the reel holding portion 75). The insertion plate 812 of the component replenishment carriage 8 is positioned below the bottom plate 711 of the feeder carriage 7, and the insertion plate 812 is inserted between the bottom plate 711 and the floor surface.

In the Z direction, the width of each slit 817 of the component replenishment carriage 8 is the same as the width (including play) of the engagement projections 719a, 719b, and the slit 817 engages (fits) with the engagement projection 719a and then engages (fits) with the engagement projection 719 b. Thereby, the position of the side plate 816 of the component replenishment carriage 8 is restrained and positioned in the horizontal direction with respect to the position of the side plate 717 of the feeder attachment carriage 7.

In the X direction, the distance between the inner wall surfaces of the two side plates 717 of the feeder shoe 7 is the same as the distance (including play) between the outer wall surfaces of the two side plates 816 of the component replenishment shoe 8, and the two side plates 816 of the component replenishment shoe 8 are engaged (fitted) between the two side plates 717 of the feeder shoe 7. Thereby, the position of the unit mounting portion 83 of the component replenishment carriage 8 is restricted and positioned in the X direction with respect to the position of the feeder mounting portion 73 of the feeder mounting carriage 7. As described above, the plurality of unit slots 831 respectively correspond to the plurality of feeder slots 731. Accordingly, in a state of being positioned in the X direction, one unit slot 831 and one feeder slot 731 corresponding to each other are opposed in the feeding direction Df.

As shown in fig. 9, two guide members 72 are provided on the bottom surface of the bottom plate 711 in front of the feeding direction Df of the two casters 714, and these guide members 72 also perform a positioning function. That is, the two guide members 72 are provided so as to extend parallel to the feeding direction Df and face each other with a gap corresponding to the width of the insertion plate 812 therebetween in the X direction. Therefore, when the insertion plate 812 advancing forward in the feeding direction Df is inserted between the two guide members 72 through between the two casters 714, the two guide members 72 restrict the position of the insertion plate 812 from both sides in the X direction. Thereby, the feeder mount carriage 7 and the component replenishment carriage 8 are positioned with each other in the X direction, and one unit slot 831 and one feeder slot 731 corresponding to each other are opposed in the feeding direction Df.

Then, finally, as shown in fig. 8 to 10, the bottom plate 811 of the component replenishment carriage 8 abuts against the bottom plate 711 of the feeder attachment carriage 7. Thus, the component replenishment carriage 8 is mounted on the feeder mounting carriage 7.

In addition, with the above-described mounting work, a unit replacement is performed in which the tape placement unit 5 mounted on the tape feeder 4 is replaced. Next, after explaining the structure of the tape placement unit 5, unit replacement will be described.

Fig. 11 is a perspective view showing the structure of the tape placing unit, fig. 12A is a side view showing the structure of the tape placing unit, fig. 12B is a cross-sectional view showing the structure of the tape placing unit, fig. 13 is a plan view showing the structure of the tape placing unit, and fig. 14 is a front view showing the structure of the tape placing unit.

The tape placement unit 5 includes: a base frame 51; a support frame 52 opposed to the base frame 51 from above; and a plurality of (two) compression coil springs 53 disposed between the base frame 51 and the support frame 52. The plurality of compression coil springs 53 are arranged in the feeding direction Df, and apply a biasing force (elastic force) to separate the base frame 51 and the support frame 52 from each other in the Z direction to the base frame 51 and the support frame 52.

The base frame 51 has a base body 511 extending in the feeding direction Df. The susceptor body 511 has a bottom surface 511a formed flat. In addition, the base frame 51 has: an upward extending portion 512 extending upward from a front end of the feeding direction Df of the susceptor body 511; and a front projection 513 projecting forward of the feeding direction Df from an upper end of the upward extending portion 512. The base frame 51 further includes a side wall plate 514 extending in the feeding direction Df at one end of the upper surface of the base body 511 in the X direction. The side wall plate 514 protrudes upward from the base body 511.

The support frame 52 has a support main 521 extending in the feeding direction Df. The support body 521 is opposed to the base body 511 of the base frame 51 from above, and the support body 521 overlaps the base body 511 in a plan view from above. The support main 521 has a horizontally formed tape mounting portion 521a on its upper surface, and the component supply tape TP can be mounted on the tape mounting portion 521 a. That is, the support frame 52 supports the component supply tape TP placed on the tape placement portion 521a of the support body 521. Further, an engagement hole 521b penetrating in the X direction is formed in the support body 521.

In addition, the support frame 52 has: a downward extending portion 522 extending downward from a front end of the support main 521 in the feeding direction Df; and a rear projection 523 projecting rearward in the feeding direction Df from a lower end of the downward extending portion 522. The rear projection 523 of the support frame 52 is opposed to the front projection 513 of the base frame 51 from below. In addition, the support frame 52 has: a downward extending portion 524 extending downward from a rear end of the support main 521 in the feeding direction Df; and a rear projection 525 projecting rearward in the feeding direction Df from a lower end of the downward extending portion 524.

The tape placement unit 5 further includes a rear frame 54 disposed rearward of the base body 511. The rear frame 54 has a rear body 541 attached to a rear end of the base body 511 in the feeding direction Df. The rear body 541 extends in the Z direction and protrudes upward from the susceptor body 511, and the bottom surface 541a of the rear body 541 and the bottom surface 511a of the susceptor body 511 are included in the same plane (i.e., coplanar). The rear frame 54 further includes a front projection 542 projecting forward in the feeding direction Df from the upper end of the rear body 541. The front projection 542 of the rear frame 54 is opposed to the rear projection 525 of the support frame 52 from above.

The plurality of compression coil springs 53 are arranged between the upper extending portion 512 of the base frame 51 and the lower extending portion 524 of the support frame 52 in the feeding direction Df. The lower end of each compression coil spring 53 is in contact with the upper surface of the base body 511 of the base frame 51, and the upper end of each compression coil spring 53 is in contact with the lower surface of the support body 521 of the support frame 52. Accordingly, the support frame 52 is biased in a direction (Z direction) away from the base frame 51 by the compression coil springs 53. In contrast, the front projections 513 and 542 face the rear projections 523 and 525 provided on both sides of the feeding direction Df of the support frame 52 from above. Accordingly, in a state where no external force is applied against the biasing force of each compression coil spring 53, the rear projection 523 and the rear projection 525 of the support frame 52 abut against the front Fang Tuqi and the front projection 542, respectively, by the biasing force of each compression coil spring 53, and the support frame 52 is stationary with respect to the base frame 51 at the uppermost point.

The compression coil springs 53 are fitted to support rods 531 protruding upward from the upper surface of the base body 511. The support bar 531 is provided to extend parallel to the Z direction and is attached to the upper surface of the susceptor body 511. On the other hand, the support body 521 is provided with an insertion hole into which the support bar 531 can be inserted in the Z direction, and the support bar 531 enters the insertion hole of the support body 521 as the base frame 51 approaches the support frame 52.

The tape placement unit 5 includes a lever 55 rotatably attached to a side wall plate 514 of the base frame 51. The lever 55 has a lever frame 551 disposed between the side wall plate 514 and the support frame 52 in a plan view. A long hole 551a is penetrated in the X direction at the front end of the lever frame 551, a bolt 56 having a head portion larger than the width of the long hole 551a is inserted into the long hole 551a from the opposite side of the side wall plate 514, and the bolt 56 is screwed with the side wall plate 514. In this way, the lever 55 is rotatably attached to the side wall plate 514 around a bolt 56 (rotation axis) parallel to the X direction. The lever 55 further includes an engagement projection 552 projecting in the X direction from the lever frame 551. The engagement projection 552 is inserted into the engagement hole 521b of the support frame 52.

The lever 55 further has a hood 553 attached to the rear end of the lever frame 551 in the feeding direction Df. The tape cover 553 has: a side wall plate 553a extending upward from the rear end of the feed direction Df of the lever frame 551; an abutting plate 553b extending in the X direction from the side wall plate 553a toward the opposite side of the side wall plate 514; and a side wall plate 553c extending downward from an end portion of the abutting plate 553b on the opposite side of the side wall plate 514. The abutting plate 553b spans the rear end portion of the support frame 52 and the front end portion of the rear frame 54 in the X direction, and the side wall plates 553a and 553c are located on both sides of the rear end portion of the support frame 52 and the front end portion of the rear frame 54 in the X direction. Further, the tape cover 553 has an abutment portion 553d protruding inward (i.e., side wall plate 553c side) from the front end of the side wall plate 553 a.

The tape placement unit 5 includes a bracket 57 disposed behind the rear frame 54. The carriage 57 has a carriage main body 571 mounted to a rear end of the rear frame 54 in the feeding direction Df. The bracket main body 571 is erected in the Z direction and protrudes upward from the rear frame 54, and the bottom face 571a of the bracket main body 571 and the bottom face 541a of the rear main body 541 are included in the same plane (i.e., coplanar).

The bracket 57 further has a unit engagement protrusion 572 provided at an upper end of the bracket main body 571. The unit engagement protrusion 572 is located at the uppermost portion of the tape placing unit 5. The unit engagement protrusion 572 has: an upward extending portion 572a extending upward from an upper end of the bracket main body 571; and flanges 572b and 572c protruding from the upper end of the upward extending portion 572a to both sides in the X direction, the unit engagement protrusion 572 having a T-shape when viewed from the feeding direction Df. These flanges 572b and 572c are each provided to extend in the feeding direction Df.

The bracket 57 has a unit engagement hole 573 provided at the lower end of the bracket main body 571. The unit engagement hole 573 has: an upward extending hole 573a extending upward from a lower end of the bracket main body 571; and grooves 573b, 573c protruding from the upper end of the hole 573a toward both sides in the X direction, the unit engagement hole 573 being configured in a T-shape when viewed from the feeding direction Df. These grooves 573b, 573c extend in the feeding direction Df. The unit engagement holes 573 are opened on both sides (front and rear sides) in the feeding direction Df. The unit engagement hole 573 and the unit engagement protrusion 572 have the same shape and size as viewed from the feeding direction Df, and are congruent.

The carriage 57 further has a tape introduction hole 574 penetrating the carriage main body 571 in the feeding direction Df. Thus, a tape guide path is formed from the tape guide hole 574 to the tape mounting portion 521a of the support frame 52 via the upper surface of the rear frame 54. Next, a tape placement operation for causing the tape placement unit 5 to hold the component supply tape TP will be described.

Fig. 15 is a perspective view showing a first step of a tape placement operation to a tape placement unit, fig. 16A is a side view showing a first step of a tape placement operation to a tape placement unit, fig. 16B is a cross-sectional view showing a first step of a tape placement operation to a tape placement unit, fig. 17 is a perspective view showing a second step of a tape placement operation to a tape placement unit, fig. 18A is a side view showing a second step of a tape placement operation to a tape placement unit, fig. 18B is a cross-sectional view showing a second step of a tape placement operation to a tape placement unit, fig. 19A is a side view showing a third step of a tape placement operation to a tape placement unit, and fig. 19B is a cross-sectional view showing a third step of a tape placement operation to a tape placement unit. Further, the tape placement work is performed by an operator.

As shown in fig. 15, 16A, and 16B, in the first step of the tape placing operation, the component supply tape TP is placed on the tape placing portion 521a of the support frame 52. In fig. 15, 16A and 16B, only a part of the component supply tape TP (the vicinity of the tape mounting portion 521 a) is shown. The component tape TP is placed by inserting the front end of the component tape TP through the tape introduction hole 574 in the rear direction of the feeding direction Df, and introducing the component tape TP to the tape placement portion 521 a. At this time, the support frame 52 rises relative to the base frame 51 to the uppermost point where the rear projection 523 and the rear projection 525 of the support frame 52 abut against the front projection 513 and the front projection 542, respectively. Therefore, the lever 55 engaged with the engagement hole 521b of the support frame 52 via the engagement projection 552 is stationary in a state rotated upward as the support frame 52 rises toward the topmost point.

As shown in fig. 17, 18A, and 18B, in the second step of the tape placing operation, the operator presses the tape cover 553 of the lever 55 against the urging force of each compression coil spring 53. Thereby, the lever 55 rotates downward, and the support frame 52 is pressed by the lever 55 via the engagement projection 552 engaged with the engagement hole 521b, and moves downward. Then, when the lower portion of the lever 55 abuts against the base frame 51, the rotation of the lever 55 is stopped. In this state, the elongated hole 551a is extended in the direction parallel to the feeding direction Df. The tape cover 553 covers the component supply tape TP from the tape introduction hole 574 to the tape mounting portion 521 a. Specifically, the abutting plate 553b of the tape cover 553 abuts on the upper surface of the component supply tape TP to restrain the component supply tape TP (tape restrained state). By this tape restraining state, the movement of the component supply tape TP is hindered. Side wall plates 553a and 553b of tape cover 553 sandwich component supply tape TP from the X direction.

In the third step of the tape laying operation, the operator pushes out the lever 55, which has stopped rotating, forward in the feeding direction Df. That is, since the rod 55 is screwed to the bolt 56 via the long hole 551a, the rod 55 can be displaced in the feeding direction Df with respect to the bolt 56 in a state where the long hole 551a is parallel to the feeding direction Df. Further, in this third step, the rotation of the lever 55 can be restricted against the urging force of the compression coil spring 53. That is, as shown in fig. 19A and 19B, the front projection 551B projects forward from the front end of the lever frame 551 of the lever 55 in the feeding direction Df. In contrast, a limiting plate 554 having a predetermined thickness is disposed at the front end portion of the upper surface of the base frame 51. As will be described later, the front projection 551b of the lever 55 functions as a rotation restriction key, and the restriction plate 554 functions as a rotation restriction stopper, and the front projection 551b contacts (engages) the restriction plate 554, thereby restricting the rotation of the lever 55.

As shown in fig. 18B, before the rotation of the lever 55 is stopped and the operator pushes out the lever 55, the bolt 56 is brought into contact with the tip of the long hole 551a in the feeding direction Df, and the lever 55 is positioned at the retracted position Le1 where the front protrusion 551B of the lever 55 is retracted rearward in the feeding direction Df from the restriction plate 554. The lever 55 is rotatable in a state where the lever 55 is located at the retracted position Le1. On the other hand, as shown in fig. 19B, after the operator pushes out the lever 55, the lever 55 is located at a contact position Lc where the bolt 56 contacts the rear end of the long hole 551a in the feeding direction Df and the front protrusion 551B of the lever 55 contacts the upper surface of the restriction plate 554. In a state where the lever 55 is located at the contact position Lc, the downward movement of the front projection 551b accompanying the rotation of the lever 55 is restricted by the restricting plate 554 contacting the front projection 551b from the lower side. That is, the rotation of the lever 55 is restricted by the restricting plate 554.

In this way, the tape placement unit 5 holding the component supply tape TP can be attached to the tape feeder 4 (fig. 20A, 20B, and 21). Fig. 20A is a side view showing a state of the tape placement unit when the tape feeder is mounted, fig. 20B is a side view showing a state of the tape placement unit when the tape feeder is mounted, and fig. 21 is a perspective view showing a state in which the tape placement unit is mounted. As shown in fig. 20B, when the tape placement unit 5 is mounted on the tape feeder 4, the lever 55 is returned to the rear in the feeding direction Df with respect to the restricting plate 554 by a function of a lever release boss 41e (fig. 25B, 27B, 29B, etc.), which will be described later, and is retracted from the contact position Lc to the retracted position Le2. The front projection 551b of the lever 55 located at the retracted position Le2 is retracted from the restricting plate 554 to the rear side in the feeding direction Df. Thereby, the lever 55 can be rotated by the urging force of the compression coil spring 53, and the belt-restrained state is released.

The retreat position Le2 is located between the contact position Lc and the retreat position Le1 in the feeding direction Df, in other words, is located on the rear side of the contact position Lc and on the front side of the retreat position Le 1. Fig. 20B shows a state immediately before the rotatable lever 55 is positioned at the retracted position Le2, and in this state, a gap Δ is provided between the front end (right end in fig. 20B) of the long hole 551a in the feeding direction Df and the bolt 56. As described later, the gap Δ is provided to ensure a movement amount of the tape placement unit 5 (further, a member other than the lever 55) required to separate from the tape feeder 4 by pressing the tape placement unit 5 attached to the tape feeder 4 toward the front side in the feeding direction Df, and corresponds to a distance between the retracted position Le1 and the retracted position Le2. In this way, in a state where the tape placing unit 5 is attached to the tape feeder 4, the lever 55 is positioned at the retreat position Le2, and a gap Δ is secured between the front end of the long hole 551a and the bolt 56.

As shown in fig. 21, a feeder engagement hole 412 is provided at the rear end of the carrier 411 of the tape feeder 4 in the feeding direction Df. Specifically, the bracket 411 has: a tray main body 411a having a rectangular parallelepiped shape extending in the feeding direction Df; and a tray protruding portion 411b protruding downward from the tray main body 411a at a rear end of the tray main body 411a in the feeding direction Df. The feeder engaging holes 412 are provided so as to penetrate the tray protruding portion 411b in the feeding direction Df, and thereby open at both ends of the tray protruding portion 411b in the feeding direction Df. The feeder engagement hole 412 has: an upward extending hole 412a extending upward from the lower end of the bracket 411; and grooves 412b, 412c protruding from the upper end of the hole 412a to both sides in the X direction, the feeder engaging hole 412 being formed in a T shape. These grooves 412b and 412c extend in the feeding direction Df. The feeder engagement holes 412 are opened on both sides (front side and rear side) in the feeding direction Df. The feeder engaging hole 412 and the unit engaging protrusion 572 have the same shape and size as viewed from the feeding direction Df, and are congruent. Therefore, the worker can attach the tape placement unit 5 to the tape feeder 4 by inserting the unit engagement protrusion 572 of the tape placement unit 5 that holds the component supply tape TP into the feeder engagement hole 412 of the tape feeder 4 from the rear in the feeding direction Df. In this way, in the tape placement unit 5 (i.e., the tape placement unit 5 attached to the tape feeder 4) in which the unit engagement protrusion 572 is engaged with the feeder engagement hole 412 at the engagement position Lg, the lever 55 is located at the retracted position Le2 as described above.

As described above, with the attachment of the subsequent tape placement unit 5 to the tape feeder 4, the replacement of the unit in which the preceding tape placement unit 5 is detached from the tape feeder 4 can be performed using the component replenishment carriage 8.

Fig. 22 is a perspective view showing a preparation operation performed on the component replenishment carriage by the operator for replacement of the unit, fig. 23A is a partial horizontal cross-sectional view showing a locking mechanism provided in the component replenishment carriage, fig. 23B is a partial vertical cross-sectional view showing a locking mechanism provided in the component replenishment carriage, and fig. 23C is a view schematically showing a locking mechanism provided in the component replenishment carriage in a vertical cross-section. Fig. 23C is a schematic diagram, and is different from fig. 23A and 23B in terms of size. As described above, in the unit mounting portion 83 of the component replenishment carriage 8, the plurality of unit slots 831 are arranged in the X direction. Each of the unit insertion grooves 831 is a T-shaped engagement protrusion having the same shape and size as the above-described unit engagement protrusion 572, and an operator can attach the tape placement unit 5 to the unit insertion groove 831 by inserting the unit engagement hole 573 of the tape placement unit 5 into the unit insertion groove 831 from the feeding direction Df.

The component replenishment carriage 8 has a locking mechanism 87 shown in fig. 23A to 23C. The lock mechanism 87 includes: a plurality of locking keys 871 provided in correspondence with the plurality of unit slots 831, respectively; and a lever 873 extending in the X direction, and a plurality of lock keys 871 are attached to the lever 873. The lever 873 is supported so as to be movable in the X direction with respect to the unit mounting portion 83, and an operator can switch between the "unlocked state" and the "locked state" shown in fig. 23A to 23C by operating a handle 875 provided at one end of the lever 873 in the X direction to move the lever 873 in the X direction.

The unit slot 831 has: an upper extension portion 831a extending in the Z direction; and flanges 831b and 831c protruding from the upper end of the upper extension portion 831a toward both sides in the X direction, the unit insertion groove 831 is configured to have a T-shape when viewed from the feeding direction Df. These flanges 831b and 831c are each provided to extend in the feeding direction Df. In addition, the inside of the upper extension portion 831a is partially formed to be hollow, and the unit socket 831 has a hollow portion 831d inside the upper extension portion 831 a. The hollow 831d is opened downward and to one side in the X direction. In contrast, the lever 873 extends in the X direction below the bracket 57 of the tape placing unit 5 attached to the unit insertion groove 831, and the lock key 871 extends from the lever 873 into the hollow 831d through the opening below the hollow 831d.

In addition, the bracket 57 of the tape placing unit 5 has a hollow portion 575 inside, and in a state where the bracket 57 of the tape placing unit 5 is attached to the unit socket 831, the hollow portion 575 of the bracket 57 and the hollow portion 831d of the unit socket 831 are adjacent to each other in the X direction to communicate with each other. In the "unlocked state", the lock key 871 is stored in the upper extension 831a and retreats from the hollow 575. Therefore, the tape placing unit 5 can be detached from the unit insertion groove 831. On the other hand, in the "locked state", the lock key 871 protrudes from the upper extension 831a toward the hollow 575. As a result, the lock key 871 engages with the hollow 575 of the tape placing unit 5, and removal of the tape placing unit 5 from the unit slot 831 is inhibited.

Therefore, when the tape placing unit 5 is mounted in the unit insertion groove 831, the operator appropriately operates the handle 875 to retract the lock key 871 from the hollow portion 575 (unlocked state), and inserts the unit engagement hole 573 of the tape placing unit 5 into the unit insertion groove 831. Next, the operator operates the handle 875 to engage the lock key 871 with the hollow 575 of the tape placing unit 5 (locked state).

In fig. 22, the component supply tape TP is omitted, but the operator mounts the tape placement unit 5 holding the component supply tape TP pulled out from the component supply reel 6 in the unit insertion slot 831. Accordingly, the operator mounts the component supply reel 6 on the reel mounting table 85, and the component supply reel 6 is wound with the component supply tape TP held by the tape mounting unit 5 attached to the unit slot 831. Thus, the preparation work for the component replenishment carriage 8 is completed.

Fig. 24 to 32C are diagrams showing operations performed in connection with replacement of the unit. In these figures, a preceding tape placement unit 5 attached to the tape feeder 4 before replacement is denoted as a tape placement unit 5A, and a subsequent tape placement unit 5 attached to the tape feeder 4 after replacement is denoted as a tape placement unit 5B. In order to clearly show the state of the tape placement unit 5 within the range hidden by the side wall of the tape feeder 4, the side wall is appropriately shown in perspective. As shown in fig. 22, this unit replacement is performed by attaching the component replenishment carriage 8, to which the tape placement unit 5 and the component supply reel 6 are attached, to the feeder attachment carriage 7 in the same manner as the above-described attachment operation.

At the start time of the mounting operation, the unit engagement protrusion 572 of the preceding tape placement unit 5A is located at an engagement position Lg (i.e., a position of the feeder engagement hole 412) with the feeder engagement hole 412 of the tape feeder 4, and the preceding tape placement unit 5A is mounted to the bracket 411 (fig. 21 and 24) of the tape feeder 4. As shown in fig. 25B, the tape feeder 4 is provided with a support boss 4e (support portion), and the tape placement unit 5 is provided with a support slit 5e (supported portion) that opens forward in the feeding direction Df, and the support slit 5e engages (is fitted) with the support boss 4e from the rear side in the feeding direction Df. That is, the support boss 4e of the tape feeder 4 supports the tape placing unit 5 (the preceding tape placing unit 5A) attached to the tape feeder 4 by engaging with the support slit 5e of the tape placing unit 5. In this way, the tape placement unit 5 attached to the tape feeder 4 (feeder main body 41) can be firmly supported by the support boss 4 e. From this state, the subsequent tape placement unit 5B attached to the component replenishment carriage 8 moves in the feeding direction Df toward the engagement position Lg in accordance with the attachment operation (fig. 24 to 26). Then, the front end of the subsequent tape placing unit 5B contacts the rear end of the preceding tape placing unit 5A (fig. 27A, 27B).

The feeder main body 41 of the tape feeder 4 includes a lever release boss 41e. In contrast, in the process of attaching the preceding tape placement unit 5A to the tape feeder 4, the lever 55 of the tape placement unit 5A is brought into contact with the lever release boss 41e, and is pushed rearward by the lever release boss 41e with respect to the restricting plate 554. Thereby, the state of the tape placing unit 5 shifts from the state of fig. 18B described above to the state of fig. 20B. Accordingly, the preceding tape placing unit 5A shown in fig. 25B is in the state of fig. 20B.

When the subsequent tape placing unit 5B in contact with the preceding tape placing unit 5A is further advanced toward the front side, the preceding tape placing unit 5A is pushed out toward the front side. However, the lever 55 of the preceding tape placement unit 5A abuts against the lever release boss 41e, and the movement of the front side of the lever release boss 41e is restricted by the lever release boss 41e. Accordingly, in the state where the lever 55 is retained, the member other than the lever 55 in the preceding tape placement unit 5A moves forward, and the unit engagement protrusion 572 of the preceding tape placement unit 5A is pulled out (withdrawn from the engagement position Lg) forward from the feeder engagement hole 412. The gap Δ between the distal end of the long hole 551a and the bolt 56 is set to be equal to or greater than the distance that the unit engagement protrusion 572 moves to remove the unit engagement protrusion 572 from the feeder engagement hole 412.

As described above, when the subsequent tape placing unit 5B moves in the feeding direction Df, the preceding tape placing unit 5A is pushed out by the subsequent tape placing unit 5B, and the unit engaging protrusion 572 of the preceding tape placing unit 5A is withdrawn from the engaging position Lg forward of the feeding direction Df and pulled out from the feeder engaging hole 412 (fig. 28A and 28B). As a result, the preceding tape placement unit 5A is separated from the tray 411 of the tape feeder 4 and falls down by its own weight (fig. 28A to 30B). Specifically, when the unit engagement protrusion 572 of the preceding tape placement unit 5A is pulled out from the feeder engagement hole 412 toward the front in the feeding direction Df, the rear end of the preceding tape placement unit 5A falls down while rotating about the support boss 4e in a state where the support slit 5e of the preceding tape placement unit 5A is engaged with the support boss 4e (fig. 28B). Then, as the preceding tape placing unit 5A falls down, the support slit 5e of the preceding tape placing unit 5A is disengaged from the support boss 4e of the tape feeder 4. In this way, the preceding tape placement unit 5A is detached from the tape feeder 4. In addition, the detached preceding tape placement unit 5A is in the state of fig. 12B.

As described above, the feeder main body 41 of the tape feeder 4 has the lever release boss 41e, and the abutment portion 553d located at the front end of the tape cover 553 of the advanced tape placement unit 5A attached to the feeder main body 41 abuts against the lever release boss 41 e. On the other hand, as described above, the lever 55 is attached to the base frame 51 by the bolt 56 inserted into the long hole 551 a. Therefore, in the above-described process in which the preceding tape placing unit 5A is pushed out by the following tape placing unit 5B, in a state in which the movement of the lever 55 of the preceding tape placing unit 5A in the feeding direction Df is impeded by the feeder main body 41, the (member other than the lever 55 of the) preceding tape placing unit 5A is moved in the feeding direction Df, and the tape restraining state of the preceding tape placing unit 5A is continuously released.

Next, as shown in fig. 31, the unit engagement protrusion 572 of the subsequent tape placement unit 5B enters the engagement position Lg from the rear in the feeding direction Df. At this time, the subsequent tape placing unit 5B maintains the tape restraining state until the subsequent tape placing unit 5B is mounted to the tray 411 of the tape feeder 4. On the other hand, as shown in fig. 31, as the unit engagement protrusion 572 of the subsequent tape placement unit 5B enters the engagement position Lg, the abutment portion 553d of the tape cover 553 of the lever 55 provided in the subsequent tape placement unit 5B abuts against the lever release boss 41e of the feeder main body 41. Then, in a state where the movement of the lever 55 in the feeding direction Df is blocked by the feeder main body 41, (the members other than the lever 55) of the tape placing unit 5 are moved in the feeding direction Df. Accordingly, the lever 55 is pushed out relatively from the contact position Lc to the retracted position Le2 by the feeder main body 41, and the front projection 551B of the feeder main body 41 is disengaged from the restricting plate 554 (fig. 32B). As a result, the lever 55 is rotated upward by the biasing force of the compression coil spring 53, the tape restraining state is released, the component tape TP is pressed against the sprocket 44, and the hole of the component tape TP is fitted with the tooth of the sprocket 44, and the component tape TP can be fed in the feeding direction Df. In this way, the unit engagement protrusion 572 of the subsequent tape placement unit 5B engages with the feeder engagement hole 412 at the engagement position Lg, and the subsequent tape placement unit 5B is attached to the tray 411 (fig. 32A and 32B) of the tape feeder 4, whereby the unit replacement is completed. Then, as shown in fig. 32C, when the component replenishment carriage 8 is pulled out from the feeder attachment carriage 7 to the rear in the feeding direction Df, the subsequent tape placement unit 5B attached to the tape feeder 4 is detached from the component replenishment carriage 8 and retained in the tape feeder 4.

According to the above-described embodiment, the tape placement unit 5 that holds the component supply tape TP that accommodates the components is mounted to the feeder body 41 of the tape feeder 4. The tape placement unit 5 includes a unit engagement protrusion 572, and the unit engagement protrusion 572 has a shape that can be engaged with the feeder engagement hole 412 of the feeder main body 41 of the tape feeder 4. The unit engagement protrusion 572 is configured to be able to enter an engagement position Lg engaged with the feeder engagement hole 412 from the rear (one side) in the feeding direction Df and to be able to withdraw from the engagement position Lg to the front (the other side) in the feeding direction Df. Therefore, the unit engagement protrusion 572 enters the engagement position Lg from the rear, and the unit engagement protrusion 572 engages with the feeder engagement hole 412, whereby the tape placing unit 5 is held by the feeder main body 41. The unit engagement protrusion 572 is retracted forward from the engagement position Lg, and the engagement between the unit engagement protrusion 572 and the feeder engagement hole 412 is released, whereby the tape placement unit 5 is disengaged from the feeder main body 41. According to this configuration, if the operator prepares the subsequent tape placement unit 5B holding the component supply tape TP in addition to the preceding tape placement unit 5A attached to the feeder main body 41, for example, the subsequent tape placement unit 5B can be attached to the feeder main body 41 from the rear side while the preceding tape placement unit 5A is detached from the feeder main body 41 to the front side. In this way, the component supply tape TP can be easily mounted on the tape feeder 4.

The unit engagement protrusion 572 has flanges 572b and 572c extending from the rear side to the front side in the feeding direction Df, and the feeder engagement hole 412 has grooves 412b and 412c extending from the rear side to the front side in the feeding direction Df. These grooves 412b and 412c have openings at both ends of the front side and the rear side in the feeding direction Df. Then, with the unit engagement projections 572 entering the engagement positions Lg, the flanges 572b and 572c are inserted into the grooves 412b and 412c through the openings, and the flanges 572b and 572c engage with the grooves 412b and 412c, whereby the tape placing unit 5 is mounted on the feeder body 41. On the other hand, as the unit engagement protrusion 572 is withdrawn from the engagement position Lg, the flanges 572b and 572c are pulled out of the grooves 412b and 412c through the openings, whereby the engagement between the flanges 572b and 572c and the grooves 412b and 412c is released, and the tape placing unit 5 is disengaged from the feeder main body 41. According to this configuration, the component supply tape TP can be easily attached to the tape feeder 4 by fitting the flanges 572b and 572c of the other tape placing unit 5 into the grooves 412b and 412c of the feeder body 41 from the rear while disengaging the flanges 572b and 572c of the one tape placing unit 5 from the grooves 412b and 412c of the feeder body 41 from the front.

In the above embodiment, the tape placement unit 5 is provided with the engagement projection, and the feeder main body 41 is provided with the engagement hole. However, even if the tape placement unit 5 is provided with the engagement hole (i.e., groove) and the feeder main body 41 is provided with the engagement protrusion (i.e., flange), the same effect can be exhibited.

In addition, the tape placing unit 5 has: a support frame 52 on which the component supply tape TP is placed; a lever 55 having a tape cover 553, the tape cover 553 being capable of approaching and separating with respect to the component supply tape TP on the support frame 52; and a compression coil spring 53 for biasing the tape cover 553 in a direction away from the component supply tape TP on the support frame 52. The lever 55 is movable between a contact position Lc where the regulating plate 554 engages with the lever 55 and a retracted position Le where the regulating plate 554 is disengaged from the lever 554, and the regulating plate 554 engages with the lever 55 located at the contact position Lc to regulate the movement of the belt cover 553 against the biasing force of the compression coil spring 53. Then, after the tape cover 553 is brought into contact with the component supply tape TP on the support frame 52 against the urging force to approach the component supply tape TP, the lever 55 is moved from the retracted position Le to the contact position Lc, whereby the tape-restraining state in which the component supply tape TP is restrained by the tape cover 553 is maintained. On the other hand, when the unit engagement protrusion 572 of the tape placement unit 5 that maintains the tape restricted state is brought into the engagement position Lg from the rear, the lever 55 is pushed out toward the retracted position Le by the feeder main body 41 and is disengaged from the restricting plate 554, whereby the tape restricted state is released.

According to this configuration, after the tape cover 553 provided in the lever 55 is brought into contact with the component supply tape TP, the lever 55 is moved from the retracted position Le to the contact position Lc and engaged with the restriction plate 554, whereby the tape-restraining state in which the component supply tape TP is restrained by the tape cover 553 can be maintained. Therefore, before the tape placement unit 5 is attached to the feeder main body 41, the component supply tape TP can be prevented from falling off from the tape placement unit 5 by the tape constraint state. When the unit engagement protrusion 572 of the tape placement unit 5, which maintains the tape restricted state, is brought into the engagement position Lg from the rear, the lever 55 is pushed out toward the retracted position Le by the feeder main body 41 and is separated from the restricting plate 554, whereby the tape restricted state is released. Therefore, after the tape placement unit 5 is attached to the feeder main body 41, the component supply tape TP held by the tape placement unit 5 can be conveyed and the component housed in the component supply tape TP can be supplied to the component supply position 40.

Further, by moving the subsequent tape placing unit 5B from the rear toward the preceding tape placing unit 5A from the state in which the preceding tape placing unit 5A is mounted to the feeder main body 41 with the unit engagement protrusion 572 of the preceding tape placing unit 5A being located at the engagement position Lg, the preceding tape placing unit 5A can be pushed out by the subsequent tape placing unit 5B. That is, it is possible to perform the unit replacement in which the unit engagement protrusion 572 of the preceding tape placement unit 5A is withdrawn from the engagement position Lg to disengage the preceding tape placement unit 5A from the feeder main body 41, and the unit engagement protrusion 572 of the following tape placement unit 5B is brought into the engagement position Lg to attach the following tape placement unit 5B to the feeder main body 41. In this way, the component supply tape TP can be easily mounted on the tape feeder 4.

The component replenishment carriage 8 is detachably attached to the tape holding unit 5B. Then, by moving the component replenishment carriage 8 from the rear toward the tape feeder 4, the preceding tape placement unit 5A is detached from the feeder main body 41 by the following tape placement unit 5B attached to the component replenishment carriage 8, and the following tape placement unit 5B is attached to the feeder main body 41, whereby the unit replacement can be performed. In this way, the component tape TP can be easily attached to the component tape TP.

In addition, the component replenishment carriage 8 has a locking mechanism 87, and when the subsequent tape placement unit 5B is locked by the locking mechanism 87, the removal of the subsequent tape placement unit 5B from the component replenishment carriage 8 is prohibited. On the other hand, when the lock of the subsequent tape placing unit 5B by the lock mechanism 87 is released, the subsequent tape placing unit 5B is allowed to be detached from the component supply carriage 8. In this structure, the subsequent tape placing unit 5B can be prevented from falling off from the component replenishment carriage 8 by the lock mechanism 87 before the subsequent tape placing unit 5B is attached to the feeder main body 41. After the subsequent tape placement unit 5B is attached to the feeder main body 41, the component replenishment carriage 8 can be separated from the feeder main body while leaving the tape placement unit 5 in the feeder main body 41 by releasing the lock mechanism 87. When the component replenishment carriage 8 is separated, the operator removes the preceding component supply reel 6 held by the feeder attachment carriage 7, and preferably moves the succeeding component replenishment carriage 8 of the component replenishment carriage 8 to the feeder attachment carriage 7.

The present invention is not limited to the above-described embodiments, and various modifications can be made to the above-described embodiments without departing from the gist thereof. Fig. 33 to 36 are side views showing modifications of the tape feeder. The tape feeder 4 according to this modification includes a unit pressing portion 49 at the rear end in the feeding direction Df. The unit pressing portion 49 includes a rotating plate 491 partially housed in a rear end portion of the feeder main body 41, and a peripheral edge portion of the rotating plate 491 has a circular arc shape centered on a predetermined central axis. The rotating plate 491 is rotatable about the center axis with respect to the feeder main body 41 by a driving force of the motor Mb or another motor. The unit pressing portion 49 further includes a projection 493 projecting in the X direction from the side surface of the rotating plate 491.

In the state of fig. 33, the projection 493 is separated in the rotation direction from the tape placement unit 5 attached to the tape feeder 4. In fig. 33 to 36, when the projection 493 rotates counterclockwise, the projection 493 contacts the tape placement unit 5 from the rear in the feeding direction Df, and pushes the tape placement unit 5 forward. As a result, the tape placement unit 5 is detached from the tape feeder 4 (fig. 36).

That is, the tape feeder 4 further includes a unit pressing portion 49, and the unit pressing portion 49 presses the tape placing unit 5 attached to the feeder main body 41 to withdraw the unit engaging protrusion 572 of the tape placing unit 5 from the engagement position Lg, thereby disengaging the tape placing unit 5 from the feeder main body 41. Therefore, the tape placement unit 5 can be detached from the feeder main body 41 without requiring manual work by an operator.

The direction in which the tape placing unit 5 is disengaged is not limited to the front, but may be the rear. In the latter case, the projection 493 may be brought into contact with the tape placing unit 5 from the front and the tape placing unit 5 may be pushed out to the rear by the projection 493.

Fig. 37 is a diagram showing an electrical structure of a modified example of the component mounter. The component mounter 1 includes a control unit 100, and the control unit 100 includes a calculation unit 110, a storage unit 120, a communication unit 130, and a user interface 140. The computing unit 110 is a processor including a CPU (Central Processing Unit: central processing unit), and the storage unit 120 is a HDD (Hard Disk Drive), for example. The communication unit 130 performs a communication function performed by the control unit 100. The user interface 140 is constituted by, for example, a touch panel display or the like.

The component mounter 1 has a reader Ra. The reader Ra has a function of reading the reel ID63 and the component ID64 of the component supply reel 6 shown in fig. 3, and an operator reads them using the reader Ra. The reader Ra transmits the reel ID63 and the component ID64 read in this way to the communication section 130, and the storage section 120 stores the reel ID63 and the component ID64 received by the communication section 130.

In this modification, the tape feeder 4 includes a reader Rb in the feeder body 41, and a unit ID58 for identifying the tape placement unit 5 is provided in the tape placement unit 5. The unit ID58 is different for each solid of the tape placement unit 5. The unit ID58 is built in the carriage main body 571, and the reader Rb is disposed at a position facing the carriage main body 571, and the carriage main body 571 is engaged with the carriage 411. The reader Rb reads the unit ID58 of the tape placement unit 5 attached to the feeder main body 41, and sends the unit ID58 to the communication unit 130, and the storage unit 120 stores the unit ID58 received by the communication unit 130.

In particular, in this modification, as shown in fig. 22, when the operator installs the tape placement unit 5 on the component replenishment carriage 8, the reel ID63 and the component ID64 of the component supply reel 6 around which the component supply tape TP held by the tape placement unit 5 is wound are read by the reader Ra. Before or after this, the operator reads the unit ID58 of the tape placing unit 5 by using the reader Ra. These read results are sent to the communication unit 130, and the storage unit 120 stores them in association with each other. That is, the unit ID58 of the tape placement unit 5 attached to the component replenishment carriage 8, the reel ID63 of the component supply reel 6 around which the component supply tape TP held by the tape placement unit 5 is wound, and the component ID64 are associated with each other, and stored as attached component information.

Next, when the tape placing unit 5 is mounted to the feeder main body 41, the reader Rb reads the unit ID58 of the tape placing unit 5 and sends it to the communication section 130. Then, the arithmetic unit 110 compares the unit ID58 received from the reader Rb with the mounting component information stored in the storage unit 120 to determine whether or not the tape feeder 4 is mounted with the appropriate tape placement unit 5.

That is, the computing unit 110 previously grasps the components to be mounted on each tape feeder 4 based on the production plan or the like. When the communication unit 130 receives the unit ID58 of the tape placing unit 5 from the reader Rb, it is determined that the component corresponding to the component ID64 associated with the unit ID58 is mounted to the tape feeder 4 to which the reader Rb belongs. When the component attached to the tape feeder 4 is a component to be attached to the tape feeder 4, the control unit 100 determines that the combination of the tape placement unit 5 and the tape feeder 4 to which the tape placement unit 5 is attached is appropriate. On the other hand, when the component attached to the tape feeder 4 is not a component to be attached to the tape feeder 4, it is determined that the combination of the tape placing unit 5 and the tape feeder 4 to which the tape placing unit 5 is attached is not appropriate. When the user interface 140 determines that the operation is not appropriate, the user interface notifies the operator of the error. The error can be notified by a sound such as a display of a screen or a buzzer.

That is, in this modification, the tape placing unit 5 has a unit ID58 (identifier) for identifying the tape placing unit 5, and the tape feeder 4 has a reader Rb that reads the unit ID58 of the tape placing unit 5 attached to the feeder main body 41. In this structure, the tape placing unit 5 attached to the feeder main body 41 can be identified based on the unit ID58 read by the reader Rb.

Further, the control unit 100 determines whether or not the combination of the tape feeder 4 and the tape placement unit 5 attached to the tape feeder 4 is appropriate based on the unit ID58 read by the reader Rb of the tape feeder 4. In this configuration, it is possible to grasp whether or not the combination of the tape placement unit 5 attached to (the feeder body 41 of) the tape feeder 4 and the tape feeder 4 is appropriate.

Further, the apparatus includes a user interface 140 (notifying unit) for notifying the operator. When the combination is determined to be inappropriate, the control unit 100 notifies the operator of an error using the user interface 140. In this configuration, when the combination of the tape feeder 4 and the tape placement unit 5 is not appropriate, the operator can quickly perform the necessary work.

As shown in fig. 37, in this modification, the component mounter 1 is provided with an automated guided vehicle 200. The automated guided vehicle 200 operates by receiving a command from the control unit 100 through wireless communication with the communication unit 130. In particular, the automated guided vehicle 200 performs the above-described mounting operation of the component replenishment carriage 8, in other words, performs the replacement of the unit using the component replenishment carriage 8.

The automated guided vehicle 200 performs the unit replacement by moving the component replenishment carriage 8 from the rear toward the component supply tape TP. In this configuration, the component supply tape TP can be mounted on the tape feeder 4 without requiring manual work by an operator.

The unit engagement protrusion 572 can also be retracted rearward in the feeding direction Df from the engagement position Lg. Therefore, the tape placing unit 5 may be removed from the feeder main body 41 of the tape feeder 4 by moving the unit engagement protrusion 572 rearward in the feeding direction Df from the engagement position Lg.

That is, the unit engagement protrusion 572 (unit engagement portion) is configured to be able to enter the engagement position Lg from the rear (one side) in the feeding direction Df and to be able to withdraw from the engagement position Lg to the rear (one side) in the feeding direction Df. Then, the unit engagement protrusion 572 enters the engagement position Lg from the rear in the feeding direction Df, and the unit engagement protrusion 572 engages with the feeder engagement hole 412, whereby the tape placement unit 5 is attached to the feeder main body 41, the unit engagement protrusion 572 withdraws from the engagement position Lg to the rear in the feeding direction Df, and the engagement between the unit engagement protrusion 572 and the feeder engagement hole 412 is released, whereby the tape placement unit 5 is detached from the feeder main body 41.

In this configuration, if the operator prepares a subsequent tape placement unit 5B holding the component supply tape TP in addition to, for example, the preceding tape placement unit 5A attached to the feeder main body 41, the preceding tape placement unit 5A can be detached from the feeder main body 41 rearward, and the subsequent tape placement unit 5B can be attached to the feeder main body 41 from the rear. In this way, the component supply tape TP can be easily mounted on the tape feeder 4.

Further, modifications different from the modification examples shown here can be added to the above-described embodiments. For example, the feeder engaging portion is constituted by an engaging hole (feeder engaging hole 412), while the unit engaging portion is constituted by an engaging protrusion (unit engaging protrusion 572). However, the feeder engaging portion may be constituted by an engaging projection, and the unit engaging portion may be constituted by an engaging hole. Other engagement holes and engagement projections may be appropriately replaced.

In contrast to the above example, the tape placing unit 5 attached to the feeder main body 41 may be supported by the feeder main body 41 by providing the support slit (support portion) to the feeder main body 41 and providing the support boss (non-support portion) to the tape placing unit 5 and engaging the support slit with the support boss. In this structure, the tape placement unit 5 attached to the tape feeder 4 (feeder main body 41) can be firmly supported by the support slit.

Alternatively, the tape placing unit 5 may be supported only by engagement of the bracket 411 of the tape feeder 4 with the bracket 57 of the tape placing unit 5 without providing the support boss or the support slit.
