Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as modes for carrying out the present invention.

Fig. 1 shows a component mounting apparatus 10. The component mounting apparatus 10 is an apparatus for performing mounting work of a component on a circuit base material 12. The component mounting apparatus 10 includes an apparatus main body 20, a substrate conveyance holder 22, a component mounting apparatus 24,

imaging devices

26 and 28, a bulk component feeder 30, and a component feeder 32. The circuit substrate 12 may be a circuit board, a three-dimensional substrate, or the like, and the circuit board may be a printed wiring board, a printed circuit board, or the like.

The apparatus main body 20 is composed of a frame 40 and a beam 42 bridged on the frame 40. The substrate transport and holding device 22 is disposed at the center in the front-rear direction of the frame 40, and includes a transport device 50 and a clamp device 52. The conveying device 50 is a device for conveying the circuit substrate 12, and the clamping device 52 is a device for holding the circuit substrate 12. Thus, the base material transport holding device 22 transports the circuit base material 12 and fixedly holds the circuit base material 12 at a predetermined position. In the following description, the conveying direction of the circuit substrate 12 is referred to as the X direction, the horizontal direction perpendicular to the X direction is referred to as the Y direction, and the vertical direction is referred to as the Z direction. That is, the width direction of the component mounting apparatus 10 is the X direction, and the front-rear direction is the Y direction.

The component mounting apparatus 24 is provided to the beam 42 and has two

work heads

60, 62 and a work head moving device 64. As shown in fig. 2, a suction nozzle 66 is detachably provided on the lower end surface of each of the

work heads

60 and 62, and the component is held by the suction nozzle 66. The work head transfer device 64 includes an X-direction transfer device 68, a Y-direction transfer device 70, and a Z-direction transfer device 72. The X-direction moving device 68 and the Y-direction moving device 70 integrally move the two

work heads

60 and 62 to arbitrary positions on the frame 40. Further, the

work heads

60 and 62 are detachably positioned and attached to the

sliders

74 and 76 in a one-touch manner without using a tool, and the Z-direction moving device 72 moves the

sliders

74 and 76 independently in the vertical direction. That is, the

work heads

60 and 62 are independently moved in the vertical direction by the Z-direction moving device 72.

The imaging device 26 is attached to the slider 74 in a downward state, and moves in the X direction, the Y direction, and the Z direction together with the work head 60. Thereby, the imaging device 26 images an arbitrary position on the frame 40. As shown in fig. 1, the imaging device 28 is disposed between the substrate transport and holding device 22 and the component supply device 32 on the frame 40 in an upward state. Thereby, the imaging device 28 images the components held by the suction nozzles 66 of the work heads 60 and 62.

The bulk component supply device 30 is disposed at one end portion in the front-rear direction of the frame 40. The bulk component feeder 32 is a device that aligns a plurality of components scattered in a scattered manner and feeds the components in an aligned state. That is, the present invention is an apparatus for aligning a plurality of elements in an arbitrary posture in a predetermined posture and supplying the elements in the predetermined posture.

The component feeder 32 is disposed at the other end portion in the front-rear direction of the frame 40 of the component mounter 24. The component supplying device 30 has a tray-type component supplying device 78 and a feeder-type component supplying device 80. The tray-type component feeder 78 is a device for feeding components in a state of being placed on a tray. The feeder-type component supply device 80 is a device that supplies components by a tape feeder 82 or a bulk component feeder device that supplies a plurality of components in a scattered state. The tape feeder 82 will be described in detail below. The components supplied from the bulk component supply device 30 and the component supply device 32 include electronic circuit components, components of solar cells, components of power modules, and the like. In addition, electronic circuit elements include elements having pins, elements having no pins, and the like.

The tape feeder 82 is detachably mounted in a slot of a tape feeder holding base 86 fixedly provided at the other end of the frame 40 of the component mounter 24. At this time, the tape feeder 82 is mounted in the positioned state in the slot of the tape feeder holding base 86, and can be mounted on the tape feeder holding base 86 with good reproducibility even if it is attached and detached. The tape feeder 82 is a braid lead component supply device that removes an axial component from a braid component (see fig. 3)88 and supplies the removed axial component to the work heads 60 and 62 of the component mounting apparatus 10 in a state in which the lead of the axial component is bent. In addition, various kinds of supply devices are detachably attached to the respective slots in a positioned state.

As shown in fig. 3, braid element 88 is comprised of a plurality of axial elements 90 and two carrier tapes 92. The axial member 90 generally includes a cylindrical member body 96 and two pins 98. The two leads 98 are substantially linear and fixed to both end surfaces of the element body 96 so as to be coaxial with the axial center of the element body 96. The axial component 90 is knitted into the two carrier tapes 92 at the tip ends of the two leads 98, that is, the end portion on the opposite side of the component main body 96, while being sandwiched between the two carrier tapes 92. Further, a plurality of axial members 90 are woven into the two carrier tapes 92 at equal intervals.

As shown in fig. 4, tape feeder 82 includes a storage box 106 and a feeder main body 107. In the following description, the direction from storage box 106 toward feeder main body 107 is referred to as the front, and the direction from feeder main body 107 toward storage box 106 is referred to as the rear. A connector 108 and two pins 109 are provided on the front end surface of feeder main body 107. When the tape feeder 82 is mounted on the tape feeder holding base 86, the connector 108 is connected to a connector connecting portion (not shown) formed on the tape feeder holding base 86 to supply power, and the pin 109 is fitted into a pin hole (not shown) formed on the tape feeder holding base 86 to accurately position the tape feeder 82. In addition, the braid element 88 is stored in the storage box 106 in a folded state. Then, the braid element 88 housed in the housing box 106 is pulled out, and the braid element 88 extends along the upper end surface of the feeder main body 107.

Inside the feeder main body 107, a feeding device 110, a lead cutting device 111, a bending device 112, and a tape cutting device 113 are disposed. As shown in fig. 5, the feeding device 110 includes a piston 114, a link mechanism 116, a feed arm unit 118, a check arm 120, and a separation mechanism 121. Piston 114 is disposed to extend substantially vertically below the inside of feeder main body 107. The link mechanism 116 is constituted by a substantially rod-shaped first arm 122 and a substantially L-shaped second arm 124. First arm 122 is disposed to extend in the front-rear direction inside feeder main body 107, and is coupled at its distal end to piston rod 126 of piston 114. The first arm 122 is swingably supported by a support shaft 128 at a central portion in the front-rear direction.

Further, a substantially L-shaped second arm 124 is disposed inside feeder main body 107 in a state where one end portion extends upward from the upper end surface of feeder main body 107 and the other end portion extends forward. The second arm 124 is coupled to the rear end of the first arm 122 at the other end extending forward. The second arm 124 is swingably supported by the support shaft 130 at a position rearward of the connection portion toward the first arm 122.

With such a configuration, when the piston 114 extends, that is, when the piston rod 126 extends upward, the front end of the first arm 122 also moves upward and the rear end of the first arm 122 moves downward as shown in fig. 6. Thereby, the tip of second arm 124 also moves downward, and the upper end of second arm 124 extending from the upper end surface of feeder main body 107 moves forward. On the other hand, when the piston 114 contracts, that is, when the piston rod 126 descends toward the inside of the piston 114, as shown in fig. 5, the front end of the first arm 122 also descends, and the rear end of the first arm 122 ascends. Thereby, the tip of second arm 124 also rises, and the upper end of second arm 124 extending from the upper end surface of feeder main body 107 moves rearward.

A feed arm unit 118 is disposed above the upper end surface of the feeder main body 107, to which the upper end of the second arm 124 extends. As shown in fig. 7 to 9, the feed arm unit 118 is constituted by a first feed arm 131, a second feed arm 132, and a third feed arm 133. Fig. 7 is a perspective view showing the feed arm unit 118 disposed on the upper end surface of the feeder main body 107 from an oblique upper perspective, fig. 8 is a side view showing the feed arm unit 118 from a side perspective, and fig. 9 is a plan view showing the feed arm unit 118 from an upper perspective.

The first feed arm 131 is disposed to extend in the front-rear direction on the upper surface of the braid element 88 extending along the upper end surface of the feeder main body 107, and is coupled to the upper end of the second arm 124 of the link mechanism 116 at the rear end. The first feed arm 131 is disposed to extend in the front-rear direction above the pin 98 of the axial member 90 knitted into the braid member 88, and a plurality of feed teeth 134 are formed at the lower end of the first feed arm 131. The plurality of feed teeth 134 engage the legs 98 of the axial element 90 of the braid element 88.

The second feed arm 132 is also disposed to extend in the front-rear direction on the upper surface of the braid element 88 extending along the upper end surface of the feeder main body 107, and is coupled at the rear end to the front end of the first feed arm 131. The second feed arm 132 is disposed to extend in the front-rear direction above the carrier tape 92 of the tape element 88, and a plurality of feed teeth 135 are also formed at the lower end of the second feed arm 132. The plurality of feed teeth 135 are engaged with the carrier tape 92 of the tape element 88.

Further, the third feed arm 133 is also disposed to extend in the front-rear direction on the upper surface of the braid element 88 extending along the upper end surface of the feeder main body 107. The third feed arm 133 is shorter than the second feed arm 132, and is coupled to the second feed arm 132 at the center in the front-rear direction of the second feed arm 132. Further, the third feed arm 133 is disposed to extend in the front-rear direction above the pin 98 of the axial member 90 of the braid member 88, and a plurality of feed teeth 136 are also formed at the lower end of the third feed arm 133. The plurality of feed teeth 136 engage the legs 98 of the axial element 90 of the braid element 88. Furthermore, the pitch of the plurality of

feed teeth

134, 135, 136 of the

respective feed arms

130, 131, 132 is the same as the arrangement pitch of the axial elements 90 in the braiding elements 88. The plurality of

feed teeth

134, 135, 136 of the

feed arms

130, 131, 132 are teeth arranged in a linear array like saw teeth.

In this way, in the feed arm unit 118, the first feed arm 131, the second feed arm 132, and the third feed arm 133 are integrally connected, and the plurality of

feed teeth

134, 135, 136 of the

feed arms

130, 131, 132 engage with the pins 98 of the tape element 88 or the carrier tape 92. The blade shape of the plurality of

feed teeth

134, 135, 136 of the

feed arms

130, 131, 132 is formed so as to stably feed the braid component 88 toward the front side of the tape feeder 82, and to prevent the return operation by being caught by the pins 98 of the axial component 90 attached to the carrier tape 92 when the

feed arms

130, 131, 132 perform the return operation. Specifically, the blade shape of the plurality of

feed teeth

134, 135, 136 of each of the

feed arms

130, 131, 132 is formed by two surfaces extending downward, and the inclination angles of the two surfaces are different. Of these two surfaces, the surface having a larger inclination angle faces forward, and the pin 98 of the axial element 90 is fed forward by this surface. Therefore, as shown in fig. 6, when the upper end of the second arm 124 is moved forward by extending the piston 114, the entire feed arm unit 118 is moved forward, and the braid element 88 is fed out toward the front side of the tape feeder 82. Thus, the braid element 88 is carried along the upper end face of the feeder body 107. That is, the braid element 88 is conveyed in a horizontal posture at a predetermined conveyance height. On the other hand, the surface having the smaller inclination angle of the two surfaces extending downward is directed rearward, and is less likely to be caught by the pin 98 during the return operation of the

feed arms

130, 131, and 132.

As shown in fig. 7 and 8, an extension portion 137 extending upward is formed at the rear end of the first feed arm 131 of the feed arm unit 118, and a coil spring 138 in an extended state is disposed between the upper end of the extension portion 137 and the feeder main body 107. Therefore, the first feed arm 131 is biased downward by the elastic force of the coil spring 138, and the entire feed arm unit is biased downward, that is, toward the braid element 88. This can increase the engaging force of the plurality of

feed teeth

134, 135, 136 against the pins 98 of the tape element 88 or the carrier tape 92, and can appropriately feed out the tape element 88 by the feed arm unit 118.

As shown in fig. 7 and 10, a pair of stoppers 139 are provided upright on the front side of the tape feeder 82 from which the braid element 88 is fed by the feed arm unit 118 so as to extend upward from between the two carrier tapes 92 of the braid element 88 extending along the upper surface of the feeder main body 107. A pair of stops 139 are upstanding at locations opposite the pair of pins 98 of the braid element 88 extending along the upper surface of the feeder body 107. As a result, the pair of legs 98 of the axial element 90 knitted into the braid element 88 fed by the feed arm unit 118 abut against the pair of stoppers 139, and the legs 98 of the axial element 90 are corrected when they are bent, and stop at the standby position before being raised toward the supply position. Thereby, the axial element 90 is positioned. Fig. 10 is a perspective view showing the tip of the tape feeder 82 from an oblique upper perspective, but in fig. 10, the feeder 110 and the feeder main body 107 are omitted. On the other hand, in fig. 7, the pin cutting device 111 is omitted.

In addition, a check arm 120 is disposed below the braid element 88 extending along the upper end face of the feeder body 107. That is, the check arm 120 is disposed in a state of facing the feed arm unit 118 with the braid element 88 extending along the upper end surface of the feeder main body 107 interposed therebetween. As shown in fig. 8, the length dimension of the check arm 120 is substantially the same as that of the feed arm unit 118, and the check arm 120 as a whole is disposed in a state of overlapping, i.e., overlapping, with the whole of the feed arm unit 118 in the front-rear direction. Teeth (see fig. 11)140 are formed on the upper edge of the check arm 120. Therefore, the teeth 140 of the check arm 120 face the plurality of

feed teeth

134, 135, 136 of the

feed arms

130, 131, 132 of the feed arm unit 118 so as to sandwich the braid element 88. Further, the edge shape of the tooth 140 of the check arm 120 is formed so as not to be caught by the pin 98 of the braiding element 88 when the braiding element 88 is fed forward by the feed arm unit 118. Specifically, as shown in fig. 5 and 6, the edge shape of the tooth 140 of the check arm 120 is formed by two faces extending upward, but the inclination angles of the two faces are different. The surface having the smaller inclination angle of the two surfaces faces rearward, and when the braiding element 88 is fed forward by the feed arm unit 118, the surface having the smaller inclination angle is less likely to be caught by the pin 98 of the braiding element 88. On the other hand, the surface having the larger inclination angle of the two surfaces faces forward, and the surface having the larger inclination angle engages with the pin 98 of the axial element 90 of the braid element 88 from the rear side during the return operation of the feed arm unit 118. Therefore, during the returning operation of the feed arm unit 118, the movement of the braiding element 88 toward the rear side, that is, the return of the braiding element 88 toward the rear side is prevented. The teeth 140 of the check arm 120 are also teeth arranged in a row of a plurality of teeth like saw teeth, similarly to the plurality of

feed teeth

134, 135, 136 of the

feed arms

130, 131, 132.

As shown in fig. 11 and 12, the separating mechanism 121 is composed of a fixed block 141, a movable block 142, and an operating lever 143. Fig. 11 is a perspective view showing the separating mechanism 121 from an oblique upper perspective, and fig. 12 is a cross-sectional view taken along line BB of fig. 11. Fixed block 141 is fixed to the upper surface of feeder main body 107. The movable block 142 is held by the fixed block 141 on the lower surface of the fixed block 141 so as to be slidable in the vertical direction, and is biased downward by a compression coil spring 144. The check arm 120 is fixed to the movable block 142.

Further, a through hole 145 is formed in the fixed block 141 so as to extend in the vertical direction, and a through hole 146 is also formed in the movable block 142 so as to extend in the vertical direction. The through hole 145 of the fixed block 141 and the through hole 146 of the movable block 142 are located on the same axis. The operating rod 143 has a substantially rod shape and is inserted through the through hole 145 of the fixed block 141 and the through hole 146 of the movable block 142. As shown in the drawing, the operating rod 143 is fixed to the movable block 142 at a lower end thereof by a nut. On the other hand, the upper end of the operating rod 143 protrudes upward from the upper surface of the fixed block 141.

The opening at the upper end of the through hole 145 of the fixed block 141 through which the operating rod 143 is inserted is formed in a stepped shape, and a first stepped surface 147 in a state of being lowered one step from the upper end surface of the fixed block 141 and a second stepped surface 148 in a state of being lowered one step from the first stepped surface 147 are formed at the stepped opening. The width of the first stepped surface 147 is larger than the width of the second stepped surface 148, and the width of the first stepped surface 147 is formed to be approximately 2 times the width of the second stepped surface 148. On the other hand, a pair of protrusions 149 extending in a direction orthogonal to the operating rod 143 is formed on the outer peripheral surface of the operating rod 143 inserted through the through hole 145 of the fixed block 141. The pair of projections 149 extend in opposite directions to each other, and the portion of the operating lever 143 where the pair of projections 149 are formed is formed in a substantially cross shape. The length of the pair of projections 149 is slightly shorter than the width of the first stepped surface 147, and the width of the pair of projections 149 is slightly shorter than the width of the second stepped surface 148.

With such a configuration, the operator pulls up the operating lever 143, and the movable block 142 moves upward against the elastic force of the compression coil spring 144. As shown in fig. 12, the operator rotates the operating lever 143 about the axial center of the operating lever 143 to engage the pair of projections 149 with the first step surface 147, thereby maintaining the movable block 142 in the upward moving state. Further, by maintaining the movable block 142 in the upward moving state, the check arm 120 fixed to the movable block 142 is also maintained in the upward moving state. When the check arm 120 moves to an upper position (hereinafter, referred to as a "raised position"), the tooth 140 of the check arm 120 engages with the pin 98 of the axial element 90 of the braid element 88. That is, the operator pulls up the operating lever 143 to engage the pair of projections 149 with the first step surface 147, thereby preventing the reverse return of the braid element 88 by the check arm 120.

On the other hand, the operator rotates the operation lever 143 about the axial center of the operation lever 143 from a state where the pair of projections 149 are engaged with the first step surface 147, and as shown in fig. 13, the pair of projections 149 are engaged with the second step surface 148. At this time, the movable block 142 moves downward by the elastic force of the compression coil spring 144, but the pair of projections 149 engage with the second stepped surface 148, and the movable block 142 is maintained in a state of moving downward. Further, by maintaining the movable block 142 in the downward moving state, the check arm 120 fixed to the movable block 142 is also maintained in the downward moving state. When the check arm 120 moves to a lower position (hereinafter, referred to as a "lowered position"), the tooth 140 of the check arm 120 does not engage with the pin 98 of the axial element 90 of the braid element 88. That is, the operator rotates the operating lever 143 from a state in which the teeth 140 of the check arm 120 are engaged with the lead 98 of the braiding element 88 to engage the pair of projections 149 with the second stepped surface 148, and the engagement of the check arm 120 with the lead 98 of the braiding element 88 is released.

As shown in fig. 6, 10, and 14, the lead cutting device 111 includes a lift block 150 and a pair of blades 151. Fig. 14 is a view showing the pin cutting device 111 from a front view point. The elevator block 150 is supported by the feeder body 107 to be able to be raised and lowered above the braid elements 88 extending along the upper surface of the feeder body 107. Further, the elevator 150 is located above the axial component 90, and the axial component 90 is located at a standby position before the braid component 88 extending along the upper surface of the feeder main body 107 is raised toward the supply position. The lift block 150 is coupled to the piston rod 126 of the piston 114 of the feeder apparatus 110 via a support arm 152. Accordingly, the lift block 150 is raised by extension of the piston 114, and the lift block 150 is lowered by contraction of the piston 114.

The pair of blades 151 of the lead cutting device 111 are detachably positioned and fixed to the lower surface of the lifter block 150 with the cutting edges thereof directed downward. One cutting edge of the pair of cutters 151 faces one of the pair of legs 98 of the axial element 90 located at the standby position in a state where the elevating block 150 is elevated. In addition, the cutting edge of the other of the pair of cutters 151 faces the other of the pair of legs 98 of the axial element 90 located at the standby position in a state where the raising and lowering block 150 is raised.

As shown in fig. 10 and 14 to 16, bending device 112 includes a piston 160, a support block 162, a pair of support members 164, a pair of pinching arms 166, and a pair of bending rollers 168. Fig. 15 is a cross-sectional view taken along line AA of fig. 4, and fig. 16 is a view showing fig. 15 from a viewpoint obliquely below from the front of the tape feeder 82. The piston 160 is disposed on the front side of the piston 114 of the feeder device 110 in the feeder main body 107 so as to extend substantially in the vertical direction. Support block 162 is disposed below axial element 90 located at the standby position, and is held in feeder main body 107 so as to be movable in the vertical direction. The support block 162 is coupled to the piston rod 170 of the piston 160, and is raised by extension of the piston 160 and lowered by contraction of the piston 160.

The support member 164 has a substantially plate shape, and a V-shaped groove 176 is formed at an upper end edge. The pair of support members 164 are disposed to face each other and fixed to the support block 162. Further, the pair of support members 164 are fixed to the support block 162 in such a manner that the grooves 176 of each other are located below the pair of pins 98 of the axial member 90 located at the standby position. Incidentally, the distance between the pin 98 of the axial member 90 located at the standby position and the upper edge of the support member 164 is very short. That is, the support member 164 is located below the pin 98 of the axial member 90 located at the standby position with a slight distance from the pin 98. Thereby, the pair of legs of the axial member 90 is positioned and supported by the pair of support members 164 along with the rise of the support block 162.

The pair of clamp arms 166 are substantially L-shaped, and are held at their lower ends by the support blocks 162 so as to be swingable in the front-rear direction. A pair of gripper arms 166 extend on the front side of the pair of support members 164 towards above the braid elements 88 extending along the upper surface of the feeder body 107. The portions of the pair of holding arms 166 extending upward of the braiding element 88 are bent at substantially 90 degrees rearward, i.e., upward of the pair of support members 164. Thus, the tip portions of the pair of gripping arms 166 are positioned above the pair of support members 164 by the elastic force of the coil spring 178 so as to grip the pair of pins 98 of the braid element 88 extending along the upper surface of the feeder main body 107.

Further, the holding arm 166 is urged rearward by the coil spring 178, and as shown in fig. 15, the holding arm 166 swings rearward, so that the tip end portion of the holding arm 166 contacts the pin 98 above the support member 164. However, as shown in fig. 16, an upper platen 180 is disposed below the clamp arm 166, and the upper platen 180 is fixed to the elevating block 150 of the lead cutting device 111. Therefore, when the lift block 150 is raised, the upper platen 180 is also raised, and the clamp arm 166 is pushed up by the upper platen 180. Thereby, as shown in fig. 17, the tip end portion of the clamp arm 166 is separated from the pin 98. That is, a gap is generated between the pin 98 of the braid element 88 extending along the upper end surface of the feeder main body 107 and the front end portion of the feeder 166.

As shown in fig. 18, the pair of nip arms 166 are coupled at their front ends by a coupling roller 182. Above the coupling roller 182, a fixing stand 186 is fixed to the upper surface of the feeder main body 107 via a pair of support legs 188. In fig. 10, fixing base 186 is not shown in order to ensure visibility of holding arm 166 and the like, and in fig. 18, feeder main body 107 is not shown in order to ensure visibility of supporting block 162 and the like. Incidentally, the fixed base 186 is disposed in front of the elevating block 150, and the pair of pinching arms 166 is positioned between the elevating block 150 and the fixed base 186 from the upper viewpoint, and only the connecting roller 182 connecting the pair of pinching arms 166 is positioned below the fixed base 186.

As shown in fig. 10, a pair of bending rollers 168 are disposed on the side surface of the elevator 150, and the elevator 150 is disposed above the braid element 88 extending along the upper end surface of the feeder main body 107. The pair of bending rollers 168 are formed so as to be rotatable around an axis extending in the front-rear direction on the side surface of the elevating block 150, and are located above the pair of legs 98 of the axial member 90 located at the standby position. The pair of bending rollers 168 are disposed at the same height in the vertical direction.

As shown in fig. 18, a detection sensor 190 is disposed on the upper surface of the fixed base 186. The detection sensor 190 is a reflective optical sensor, and irradiates light in a substantially horizontal direction toward the rear. The irradiation direction thereof will be described in detail later, but the axial member 90 supported by the pair of support members 164 when the support block 162 of the bending apparatus 112 is raised is located in the irradiation direction. And, in this position, the axial element 90 is fed. Therefore, the detection sensor 190 is a sensor for detecting whether the axial member 90 is supplied at the supply position.

As shown in fig. 5 and 19, the tape cutting device 113 includes a piston 200, a holding block 202, and a pair of cutters 204. Fig. 19 is a perspective view showing the tip of the tape feeder 82 from an oblique upper perspective. The piston 200 is disposed on the front side of the piston 160 of the bending device 112 in the feeder main body 107 so as to extend in the substantially vertical direction. Holder block 202 is supported by feeder main body 107 so as to be able to move up and down on the front side of fixing base 186. The holding block 202 is coupled to a piston rod 206 of the piston 200 via a support arm 208. Thus, the holding block 202 is raised by the extension of the piston 200, and the holding block 202 is lowered by the contraction of the piston 200.

The pair of cutters 204 are fixed to the front side surface of the holding block 202 with the cutting edges thereof directed downward, on the front side surface of the holding block 202. The cutting edges of the pair of blades 204 extend downward from the lower end surface of the holding block 202, and are positioned above the pair of carrier tapes 92 of the tape element 88 extending along the upper end surface of the feeder main body 107. In the braid element 88 shown in fig. 19, although the details will be described later, the pins 98 are cut by the pin cutting device 111 and the axial direction element 90 is cut off, and the braid element 88 is a tape after supply, and therefore, the braid element 88 is formed as a waste tape including a pair of carrier tapes 92 and the pins 98 remaining on each carrier tape 92.

In the component mounting apparatus 10, the above-described configuration allows the circuit substrate 12 held by the substrate transport and holding apparatus 22 to be subjected to component mounting work. Specifically, the circuit substrate 12 is conveyed to the working position, and is fixedly held by the holding device 52 at this position. Next, the imaging device 26 moves above the circuit substrate 12 to image the circuit substrate 12. Thereby, information on the positions of a pair of through holes (not shown) formed in the circuit substrate 12 is obtained. In addition, the bulk component feeder 30 or the component feeder 32 feeds components at a predetermined feeding position. The supply of components by feeder-type component supply device 80 of component supply device 32 is described in detail below.

In the feeder-type component supply device 80, in the tape feeder 82, the braid component 88 extending along the upper end surface of the feeder main body 107 is fed toward the component supply position by the operation of the piston 114 of the feeding device 110. That is, as described above, when the upper end of the second arm 124 is moved forward by a predetermined distance by the extension of the piston 114, the feed arm unit 118 also moves forward, and the tape element 88 is fed toward the element supply position located on the front side of the tape feeder 82. When the braiding element 88 is fed forward to the stroke end, i.e., the position of the extension end, of the piston 114 of the feeding device 110, the pin 98 of the axial element 90 abuts against the stopper 139, and the pin of the axial element fed at the feeding position is corrected for warping and bending, and is positioned at the standby position.

Further, the lifter 150 of the pin cutting device 111 is raised along with the extension of the piston 114. That is, when the braid element 88 is pushed up toward the front, the lift block 150 is lifted up. At this time, when the lift block 150 is raised, the clamp arm 166 is pushed up by the upper platen 180 as described above, and thus the tip portion of the clamp arm 166 is separated from the lead pin 98 as shown in fig. 17. Accordingly, the braid element 88 is properly fed forward without being obstructed by the clamp arm 166, and the pin 98 of the axial element 90 is positioned in abutment with the stopper 139.

In a state where the pin 98 of the axial element 90 is located at the standby position, the groove 176 of the support member 164 is located below the pin 98, and the clamp arm 166 is located above the pin 98. In addition, when the pin 98 of the axial element 90 is positioned by the stop 139, the piston 114 contracts. At this time, the lift block 150 also moves down, the upper platen 180 releases the pinching arm 166 from being pushed up, and the pinching arm 166 swings toward the rear, that is, the pin 98 of the axial element 90 located at the standby position by the elastic force of the coil spring 178. Therefore, the pin 98 of the axial element 90 located at the standby position is pressed downward from above by the clamp arm 166. Thereby, the pin 98 is pressed by the clamp arm 166 with elastic force toward the groove 176 of the support member 164 located below the pin 98, so that the pin 98 is clamped by the support member 164 and the clamp arm 166 inside the groove 176 as shown in fig. 15.

In addition, in a state where the pin 98 of the axial member 90 in the standby position is sandwiched by the support member 164 and the sandwiching arm 166, the piston 114 is further contracted, and the lift block 150 is further lowered. At this time, the cutter 151 fixed to the elevator 150 is lowered together with the elevator 150, and as shown in fig. 20, the pin 98 of the axial element 90 located at the standby position is cut by the cutter 151. Thereby, the axial members 90 are separated from the carrier tape 92. Further, since the pin 98 is held by the support member 164 and the holding arm 166, the pin 98 is properly cut by the cutter 151. Further, the axial component 90 is separated from the tape component 88 by cutting the leads 98, and the tape component 88 is formed as a waste tape including the pair of carrier tapes 92 and the leads 98 remaining on the respective carrier tapes 92.

Further, when the piston 114 contracts, the upper end of the second arm 124 moves rearward by the link mechanism 116, and therefore the feed arm unit 118 moves rearward. That is, when the piston 114 contracts, the feed arm unit 118 moves in a direction opposite to the direction in which the braiding element 88 is fed toward the feeding position in order to return the feed arm unit 118 to the position before the braiding element 88 is fed toward the feeding position. At this time, the pin 98 of the axial element 90 incorporated in the braid element 88 engages with the check arm 120, thereby preventing the braid element 88 from moving rearward. As described above, the angles of the

feed teeth

134, 135, 136 of the

feed arms

130, 131 are set to angles that do not engage with the pins 98 of the braiding elements 88 when the feed arm unit 118 moves rearward. Therefore, the arm unit 118 is returned rearward without moving the braid element 88 rearward with the contraction of the piston 114.

When the pin 98 is cut and the axial member 90 is separated from the braid member 88, the piston 160 of the bending device 112 is extended and the support block 162 is raised, so that the axial member 90 in a state of being sandwiched by the support member 164 and the sandwiching arm 166 is raised as shown in fig. 21. At this time, the pair of legs 98 of the axial member 90 abuts against a pair of bending rollers 168 disposed on the side surface of the elevating block 150. As the piston 160 extends, that is, the support block 162 rises, the pair of legs 98 abutting the pair of bending rollers 168 are bent downward by the pair of bending rollers 168 as shown in fig. 22. At this time, the piston 160 further extends, the support block 162 further rises, and the pin 98 is bent in a direction orthogonal to the axial center of the element body 96 as shown in fig. 23. Further, since the pin 98 is nipped by the support member 164 and the nip arm 166, the pin 98 is properly folded by the folding roller 168.

After the leg 98 is bent by the bending roller 168, the axial element 90 is lifted together with the supporting block 162 in a state where the leg 98 on the element body side which is not bent is sandwiched by the supporting member 164 and the sandwiching arm 166. At this time, as shown in fig. 24, the coupling roller 182 disposed at the tip of the grip arm 166 abuts against the lower surface of the fixing base 186. Therefore, as shown in fig. 25, the holding arm 166 swings in a direction away from the held pin 98, i.e., forward. Thereby, the support member 164 and the grasping arm 166 release the grasping of the pin 98. That is, the axial member 90 is positioned at the pair of pins 98, and is formed in a state of being supported from below only by the pair of support members 164.

When the support block 162 is raised until the connection roller 182 abuts against the fixed base 186 and the grip of the pin 98 by the grip arm 166 is released, the piston 160 is extended longest and the axial element 90 supported by the support member 164 is lifted to the highest position. At this position, the axial element 90 is supplied with the grip of the grip arm 166 on the pin 98 released. That is, when the piston 160 is extended to the longest side and the supporting block 162 is raised to the highest side, the position of the axial component 90 supported by the supporting member 164 is set to the component supply position of the tape feeder 82. In this way, in the tape feeder 82, the pins 98 in a state of being sandwiched between the support member 164 and the clamp arm 166 are cut and bent, and then the clamp of the pins 98 by the clamp arm 166 is released. The axial component 90 is supplied at the component supply position in a state of being supported by the support member 164. That is, in the tape feeder 82, the axial components 90 are supplied one by one from the upper end surface of the feeder main body 107 in a state of being positioned at a position higher than the upper end surface, that is, a supply position and being lifted up.

The detection sensor 190 disposed on the upper surface of the fixed base 186 is disposed at the same height as the supply position of the axial component 90, and irradiates light toward the supply position of the axial component 90. Therefore, the detection sensor 190 can detect whether or not the axial element 90 is supplied at the supply position, based on whether or not the irradiated light returns to the light receiving section. This makes it possible to appropriately identify the timing of supplying the axial component 90 by the tape feeder 82 and the presence or absence of supply of the axial component 90. Further, the detection sensor 190 can confirm whether or not the axial component is supplied at the supply position in an appropriate posture. In addition, the work heads 60, 62 can confirm whether the axial element 90 is held by confirming the negative pressure for holding the axial element 90. That is, whether or not the axial component 90 is properly supplied at the component supply position of the tape feeder 82 can be checked without fail during the holding time. When the supply of the axial component 90 is detected by the detection sensor 190, one of the work heads 60 and 62 moves upward of the axial component 90, and the axial component 90 is held by the suction nozzle 66 at the component main body 96. The detection sensor 190 may be any of various sensors such as a sensor that mechanically detects the axial member 90 by contact, and may be provided at any height.

Next, the working heads 60 and 62 holding the axial component 90 are moved upward of the imaging device 28, and the imaging device 28 images the axial component 90 held by the suction nozzle 66. Thereby, information on an error of the holding position of the component is obtained. Next, the working heads 60 and 62 holding the axial component 90 are moved upward of the circuit base material 12, and the holding posture of the held component is adjusted based on the position of the through hole formed in the circuit base material 12, the holding position of the component, and the like. At this time, the movement and holding posture of the work heads 60 and 62 are adjusted so that the pair of through holes formed in the circuit substrate 12 and the tip ends of the pair of pins 98 of the axial component 90 held by the suction nozzle 66 are aligned in the vertical direction. Then, the working heads 60 and 62 are lowered, the pair of pins 98 are inserted through the pair of through holes, and the axial element 90 is mounted on the circuit base 12. In this way, in order to insert the pair of leads 98 into the pair of through holes, the pair of leads 98 are bent in the same direction in the tape feeder 82.

In the tape feeder 82, the braid element 88 with the leads 98 cut by the lead cutting device 111, that is, the waste tape is cut by the leads 98 and the axial element 90 is separated, and then is also fed forward by the operation of the feeding device 110. And is fed to the tip of tape feeder 82 via the lower side of fixing table 186. As shown in fig. 19, a tape cutting device 113 is disposed on the tape feeder 82 on the front side of the component supply position, and a pair of blades 204 of the tape cutting device 113 is positioned above a pair of carrier tapes 92 of the waste tape. Accordingly, the piston 200 of the tape cutting device 113 contracts, and the holding block 202 descends, and the pair of carrier tapes 92 of the waste tape is cut by the pair of cutters 204 fixed to the holding block 202. Thereby, the waste tape is finely cut and discarded.

In this way, in the tape feeder 82, the braid element 88, i.e., the waste tape, after the pin 98 is cut by the pin cutting device 111 is also fed forward after the pin 98 is cut, and is cut by the tape cutting device 113 on the front side of the tape feeder 82. Therefore, the feed arm unit 118 that feeds out the braid element 88 toward the feeding position extends from the near side of the feeding position beyond the feeding position to the tape cutting device 113.

In detail, as described above, in the pin cutting device 111, the pin 98 of the axial member 90 located at the standby position is cut, so that the axial member 90 is separated from the braid member 88. Then, the separated axial member 90 is lifted by the pair of support members 164, and the axial member 90 is supplied at the supply position. As shown in fig. 8 and 9, the feed arm unit 118 extends from the front side of the feeding position beyond the feeding position to the tape cutting device 113. Specifically, the first feed arm 131 of the feed arm unit 118 is provided to extend in the extending direction of the tape element 88 before reaching the front side of the lift block 150 of the lead cutting device 111, that is, the supply position. Furthermore, a first feed arm 131 extends over the pin 98 of the taping element 88. The second feed arm 132 of the feed arm unit 118 is extended from the front side of the lift block 150 of the lead cutting device 111, i.e., before reaching the supply position, to the lower side of the holding block 202 of the tape cutting device 113 via the lower side of the lift block 150, i.e., the supply position. Further, a second feed arm 132 is provided extending above the carrier tape 92 of the tape element 88. In addition, the third feed arm 133 of the feed arm unit 118 is provided extending in the extending direction of the braid element 88 between the lift block 150 of the pin cutting device 111 and the holding block 202 of the tape cutting device 113. Furthermore, a third feed arm 133 extends over the pin 98 of the taping element 88.

The pins 98 of the braid element 88 are cut by a pair of cutters 151 fixed to a lift block 150 of the pin cutting device 111, and the axial elements 90 separated from the braid element 88 by the cutting of the pins 98 are supplied. Therefore, the first feed arm 131 engages with the pin 98 of the braid element 88 before the axial element 90 is separated, and the third feed arm 133 engages with the pin 98 of the braid element 88 after the axial element 90 is separated. The second feed arm 132 engages with the carrier tape 92 of the braid element 88 before and after the axial element 90 is separated. Thus, the feed arm unit 118 extends from the near side of the feeding position beyond the feeding position to the tape cutting device 113. That is, the feed arm unit 118 is disposed in a state of extending in the extending direction of the braiding element 88 from the near side of the feeding position beyond the feeding position to the tape cutting device 113. Also, the feed arm unit 118 engages with the braid element 88 before the axial element 90 is separated from the braid element 88 and after the axial element 90 is separated from the braid element 88. This enables the tape element 88 to be appropriately fed to the tape cutting device 113 through the supply position, and the lead pin 98 and the residual tape to be cut.

When the feed arm unit 118 is returned rearward, the entire check arm 120 that prevents the braid element 88 from returning rearward is disposed in a state of overlapping the feed arm unit 118 in the extending direction of the braid element 88. That is, the check arm 120 overlaps the feed arm unit 118 as a whole in the extending direction of the tape member 88, and the check arm 120 and the feed arm unit 118 overlap from the viewpoint of the up-down direction. That is, as shown in fig. 8, the check arm 120 extends from the rear side of the first feed arm 131, specifically, from below the extension portion 137 to a position immediately before reaching the cutter 204 of the tape cutting device 113. Therefore, when the feed arm unit 118 is returned toward the rear, the braid element 88 can be desirably prevented from returning toward the rear over the entire area of the check arm 120.

In particular, each

feed tooth

134, 135, 136 of feed arm unit 118 extends toward the upper surface of braiding element 88 and tooth 140 of check arm 120 extends toward the lower surface of braiding element 88. That is, the feed arm unit 118 and the check arm 120 are arranged to face each other, and the braid element 88 is sandwiched between the feed arm unit 118 and the check arm 120. Accordingly, when the feed arm unit 118 is returned rearward, the check arm 120 engages with the pin 98 of the braiding element 88 from below the braiding element 88, and the braiding element 88 and the residual braid can be desirably prevented from returning rearward and shifting.

In this manner, in the tape feeder 82, the check arm 120 engages the pin 98 of the tape element 88, desirably preventing the tape element 88 from returning rearward. However, when replacing the tape feeder 82 with the tape element 88, the tape element 88 needs to be removed from the tape feeder 82. When the worker removes the braid element 88 from the tape feeder 82, the braid element 88 extending from the rear end of the feeder main body 107 is pulled out rearward, but since the check arm 120 engages with the braid element 88, the pulling out operation of the braid element 88 becomes very difficult. Therefore, the tape feeder 82 is provided with a separating mechanism 121. As described above, in the separation mechanism 121, the operator pulls up the operating lever 143 to engage the pair of protrusions 149 with the first step surface 147, thereby raising the check arm 120 toward the braiding element 88 and engaging the check arm 120 with the leg 98 of the braiding element 88. On the other hand, in the separation mechanism 121, as described above, the operation lever 143 is rotated to engage the pair of projections 149 with the second stepped surface 148, so that the check arm 120 is separated from the braiding element 88, and the engagement of the check arm 120 with the lead 98 of the braiding element 88 is released. That is, the engagement of the check arm 120 with the braiding element 88 and the release of the engagement of the check arm 120 with the braiding element 88 can be easily switched by the operation of the separation mechanism 121. Therefore, when the braid element 88 is replaced in the tape feeder 82, the braid element 88 can be easily pulled out from the tape feeder 82 only by operating the separation mechanism 121 to separate the check arm 120 from the braid element 88.

The tape feeder 82 is an example of a tape feeder. Taping element 88 is one example of a taping pin element. Axial member 90 is an example of a pin member. The carrier tape 92 is an example of a carrier tape. The feed arm unit 118 is an example of a feed claw. The check arm 120 is an example of a check pawl. The separation mechanism 121 is an example of a separation mechanism.

The present invention is not limited to the above-described embodiments, and can be implemented in various forms in which various changes and modifications are made based on the knowledge of those skilled in the art. For example, in the above-described embodiment, the position lifted by the support member 164 after the axial member 90 is cut off from the braiding member 88 is formed as the component supply position, but the position where the axial member 90 is cut off from the braiding member 88 may be the component supply position. Further, a position on the front side of the position where the axial direction element 90 is cut off from the braid element 88 may be the element supply position. That is, after the axial element 90 is cut off from the braid element 88, the cut axial element 90 may be sent to the supply position.

Further, the present invention is applicable to a tape feeder that supplies axial components 90, but may also be applied to a tape feeder that supplies radial components. That is, the present invention can be applied to a feed claw and a check claw that feed a radial component incorporated in a carrier tape to a supply position.

In the above embodiment, the feed arm unit 118 engages with the pins 98 of the tape element 88 or the carrier tape 92, but may engage with the element body 96. In addition, when the carrier tape 92 has a feed hole, the feed arm unit 118 may engage with the feed hole. In the above embodiment, the check arm 120 engages with the pin 98 of the tape element 88, but may engage with the element body 96 or the carrier tape 92. When the carrier tape 92 has a feed hole, the check arm 120 may be engaged with the feed hole.

In the above embodiment, the

feed teeth

134, 135, 136 of the

feed arms

130, 131, 132 and the teeth 140 of the check arm 120 are saw-toothed teeth arranged in a state where a plurality of teeth are linearly arranged in a line, but may be wheel-shaped or gear-shaped teeth. That is, the plurality of teeth may be arranged in a circular ring shape. Further, the present invention may be configured not by a plurality of teeth but by one tooth. The braid elements 88 may be arranged at positions separated from each other without overlapping each other in the width direction.

In the above embodiment, the feed arm unit 118 and the check arm 120 are disposed to face each other with the braid 88 interposed therebetween, but both the feed arm unit 118 and the check arm 120 may be disposed on one of both surfaces of the braid 88. In addition, in the above-described embodiment, feed arm unit 118 and check arm 120 are disposed so as to overlap in the extending direction of braid element 88, but feed arm unit 118 and check arm 120 may be disposed so as not to overlap in the extending direction of braid element 88.

In the above embodiment, the separating mechanism 121 separates the check arm 120 from the braiding element 88 by moving the check arm 120 downward, but for example, the check arm 120 may be moved laterally to separate the check arm 120 from the braiding element 88. That is, the separating mechanism 121 may move the check arm 120 in any manner as long as the check arm 120 can be separated from the braid element 88. In the separation mechanism 121, the check arm 120 moves linearly, but may move in various manners such as swinging or turning.

Claims

1. A tape feeder which cuts out a plurality of pin components held by a carrier tape from a tape-wound pin component including the carrier tape and the pin components, and supplies the pin components cut out from the carrier tape at a supply position,

the tape feeder includes:

a feed claw that feeds the braid pin element to the feed position;

a non-return pawl preventing movement of the braid pin element in a direction opposite to the feed direction of the feed pawl; and

a separation mechanism that separates the non-return claw from the braid pin element when the braid pin element is detached from the tape feeder.

2. The tape feeder of claim 1,

the feed pawl and the non-return pawl are arranged to overlap in the feed direction of the taping pin element.

3. The tape feeder of claim 1 or 2,

the feed pawl is disposed opposite to the check pawl.

4. The tape feeder of any one of claims 1 to 3,

at least one of the feed claw and the non-return claw is disposed so as to pass the feeding position from a front side of the feeding position in a feeding direction of the braid lead member.
