One end of the spiral spring is fixed on the fixed seat, and the other end of the spiral spring is fixedly connected with one end of the pushing piece strip, so that the pushing piece strip has a tendency of winding on the spiral spring.

The push blade 422 has a curled portion 422a and an extended portion 422b, with a push head 422c at an end of the extended portion 422b remote from the curled portion 422 a. Both the curled portion 422a and the extended portion 422b are of a sheet structure, the curled portion 422a being a portion coiled around the spiral spring, and the extended portion 422b being a portion of the push strip 422 being straightened out of the spiral spring. The thickness of the push head 422c is greater than the thickness of the extension 422b. In this embodiment, when the extension portion 422b extends in a direction away from the curled portion 422a, that is, in a direction toward the magazine 3, the curled portion 422a is stretched into a straight line, thereby becoming the extension portion 422b. The curled portion 422a of the push strip 422 has a tendency to re-change the extended portion 422b into the curled portion 422a under the action of the spiral spring, that is, the original extended portion 422b automatically curls around the spiral spring if no external force is applied to fix the extended portion 422b or pull the extended portion 422b.

The first limiting plate 12 is provided with a through hole 121 through which the push head 422c can pass, and the extending part 422b drives the push head 422c to extend towards the chip socket in the material pipe 32 close to the magazine 3, so that the push head 422c pushes the chip socket to move to the feeding end 5 along the length direction of the material pipe 32.

In the present embodiment, the driving unit 423 is a driving motor 423.

The driving motor 423 is fixed to the base 41, and is connected to the driving wheel 425 through the transmission part 424 to drive the driving wheel 425 to rotate, thereby providing power for extending the extension part 422b. In this embodiment, the driving motor 423 is a speed adjusting motor, and the rotation speed of the driving motor 423 can be adjusted as required, so as to change the rotation speed of the driving wheel 425.

The driving part 424 sequentially includes a first rotating wheel 424a coupled to the driving motor 423, a second rotating wheel 424b coupled to the first rotating wheel 424a, a driving wheel shaft 424c coupled to the second rotating wheel 424b and the driving wheel 425, and a bearing 424d mounted on the driving wheel shaft 424c between the second rotating wheel 424b and the driving wheel 425. A capstan mounting plate 424e is also provided between the capstan 425 and the bearing 424d for mounting the capstan 425.

The driving wheel 425 is arranged at the lower end of the extending part 422b of the pushing strip 422 and is closely attached to the extending part 422b, the driven wheel 426 is arranged at the upper end of the extending part 422b and is opposite to the driving wheel 425, and the driving wheel 425 is matched with the driving wheel 425 to press the extending part 422b. In this embodiment, driven wheel 426 corresponds to a pinch roller that compresses extension 422b.

A driven wheel 426a is connected to the driven wheel 426, a hanger plate 426b is fixedly connected to both ends of the driven wheel 426a, and a driven wheel mounting plate 426c is further provided between the driven wheel 426 and the hanger plate 426b on the side away from the base 41. The top of the driven wheel mounting plate 426c is fixedly connected with the driving wheel mounting plate 424e, and since the driven wheel axle 426a can move up and down, the driven wheel 426 connected with the driven wheel 426a and the hanger plate 426b can also move up and down, thereby pressing or releasing the extension portion 422b of the push bar 422. A connection plate 426e is also connected to the hanger plate 426b for connecting the two hanger plates 426b. The two hanger plates 426b and the connection plate 426e together form a U-shaped connection.

Under the drive of the driving motor 423, the driving wheel 425 rotates, and the driving wheel 425 and the driven wheel 426 compress the extension part 422b together, so that under the action of friction force, the driven wheel 426 rotates, and simultaneously the extension part 422b extends towards the direction approaching the magazine 3, and the extension of the curled part 422a becomes new or even part 422b, so that the chip socket in the material pipe 32 is pushed to move towards the feeding end. The state after the pusher bar extension 422b is extended is shown in fig. 7.

The limiting assembly 43 has a positioning unit 431 and a limiting unit 432.

The positioning block 431 is disposed between the driving wheel 425 and the first limiting plate 12, and is fixedly mounted on the first limiting plate 12, and includes a positioning block 431a located at the lower end of the extending portion 422b of the push strip 422 and a positioning cover plate 431b located at the upper end of the extending portion 422 b. The positioning cover plate 431b is mounted on the positioning block 431a, and a hole capable of allowing the upper extension portion 422b to pass through is formed between the positioning cover plate 431b and the positioning block 431a, and the thickness of the hole is equal to that of the extension portion 422b or slightly greater than that of the extension portion 422b but less than that of the push head 422c, so that the push head 422c is clamped at one end of the positioning block 431 close to the magazine 3.

The limiting unit 432 is disposed between the driving wheel 425 and the fixed seat 421, and has a limiting block 432a and a limiting cover 432b. The positioning block 432a is fixedly mounted on the base 41, and has a slot through which the extension portion 422b of the pusher bar 422 can pass, and the limiting cover 432b is mounted on the positioning block 432 a.

The retraction unit 44 is mounted on an upper end of the driven wheel 426 for resetting the push bar 422 when the push head 422c reaches the end position.

A horizontally disposed rotating shaft 441 is mounted on top of the drive wheel mounting plate 424e, and a rotating lever 442 is rotatably mounted on the rotating shaft 441 and has a free end 442a and a fixed end 442b. Wherein the fixed end 442b is fixedly connected to the connecting plate 426e, and the free end 442a is a free end.

One end of the elastic member is fixedly connected to the driving wheel mounting plate 424e, and the other end is fixedly connected to the connecting plate 426e, and a force toward the driving wheel 425 is applied to the connecting plate 426 e.

The reset cylinder 443 is mounted on the housing 1 adjacent to the rotating lever 442 and includes a cylinder body 443a and a cylinder pusher 443b coupled to the cylinder body 443a adjacent to the free end 422a of the rotating lever 442. The cylinder body 443a pushes the cylinder pushing block 443b to move, pushing the free end 442a of the rotating rod 442 to move downward, thereby rotating the rotating rod shaft 441, and thus, the fixed end 442b to move upward. Since the fixed end 442b moves upward, the connection plate 426e fixedly connected to the fixed end 442b, the hanger plates 426b connected to both ends of the connection plate 426e, the driven wheel shaft 426a connected to the hanger plates 426b, and the driven wheel 426 mounted on the driven wheel shaft 426a move upward together, that is, the driven wheel 426 moves in a direction away from the driving wheel 425, thereby releasing the extension 422b of the pusher bar 422. When the extension portion 422b is released, the push head 422c of the push strip 422 is contracted towards the direction approaching the first limiting plate 12, and the original portion of the extension portion 422b is automatically curled around the original curled portion 422a, so that the push strip 422 is reset.

The reset button 444 is mounted on the housing 1 with one end exposed on the outer surface of the housing 1 and the other end abutting against the free end 442a of the rotation rod 441, and when the operator presses the reset button 444, the reset button 444 pushes the free end 442a to move downward, thereby rotating the rotation rod shaft 441 about the rotation rod shaft 442b to move upward. The subsequent operation is the same as the operation of the reset cylinder 443 pushing the rotation lever 441, and will not be described again. Thus, depressing the reset button 444 may also cause the follower 426 to release the extension 422b of the pusher bar 422, thereby allowing the pusher bar 422 to reset.

The first starting detection element is a first infrared sensor, and the second starting detection element is a second infrared sensor.

The first infrared sensor is disposed between the driving wheel 425 and the positioning unit 431, near the extension portion 422b of the push strip 422, for sensing whether the push strip 422 is at the start position and transmitting a corresponding signal to the feeding control device 20. The second infrared sensor is disposed between the fixed seat 421 and the limiting unit 432, and is close to the extending portion 422b of the push strip 422, and is used for sensing whether the push strip 422 is at the end position and sending a corresponding signal to the feeding control device 20.

In this embodiment, a first through hole matched with the first infrared sensor and a second through hole matched with the second infrared sensor are disposed at the corresponding position of the push strip 422.

When the operator presses the parameter setting selection button 642d, the input display unit 65 displays the parameter setting screen 643, when the operator presses the teaching selection button 642e, the input display unit 65 displays the teaching screen 644, and when the operator presses the event recording selection button 642f, the input display unit 65 displays the event recording screen 646.

Fig. 11 is a schematic diagram of a parameter setting screen according to an embodiment of the invention.

As shown in fig. 11, the input display section 65 displays a parameter setting screen 643 for an operator to set the moving speed of the drive motor, that is, the moving speed of the pusher bar pushing the chip socket.

Once the operator confirms the inputted parameters, the predetermined speed storage 62 stores the movement speed inputted by the operator as a new predetermined speed. In this embodiment, the set pusher bar moving speed was 15mm/s.

The start position determination unit 67 determines whether the push bar 422 is at the start position based on the corresponding signal transmitted from the first start detection element, and the end position determination unit 68 determines whether the push bar 422 is at the end position based on the corresponding signal transmitted from the second start detection element. The start position of the pusher 422 is the position of the pusher 422 when the pusher 422c is not extended into the feed tube 32, and the end position is the position of the pusher 422c when the pusher 422c is feeding the last chip socket in the feed tube 32 to the feed end 5.

The input display unit 65 displays a status display control screen 642 for the operator to confirm the start of feeding, that is, to press the start button 642a, and once the operator presses the start button 642a, the start position determination unit 67 determines whether the pusher 422 is at the start position, and if so, the start position determination unit 67 determines that the pusher 422 is at the start position for the first time, and the control unit 71 controls the lifting mechanism 2 to move to a position corresponding to the 1 st position coordinate stored in the position information storage unit 63 such that the bottommost tube 32 in the magazine 3 is opposed to the pusher 422c of the pusher 422, and simultaneously displays the position coordinate corresponding to the position of the lifting mechanism 2 at that time in the coordinate display area 642f of the status display control screen 642.

Once the elevating mechanism 2 moves to a position corresponding to the position coordinates, the control part 77 starts and controls the driving motor to operate according to the predetermined speed stored in the predetermined speed storage part 62, so that the push strip 422 pushes the chip socket at the predetermined speed of 15mm/s, and feeding of the single material tube is achieved.

When the end position determining portion 68 determines that the push bar 422 is at the end position, the control portion 77 controls the driving motor to stop, that is, controls the advancing unit to stop, and the control portion 70 further activates the reset cylinder 443 to push the push rod 442 to rotate, so that the driven wheel 426 releases the push bar 422. Further, the pusher strip 422 is retracted away from the loading end 5 by the scroll spring. When the start position determining unit 67 determines that the push bar 422 is at the start position during the push bar retraction, the control unit 70 controls the reset cylinder 443 to release the push rod 442, so that the driven wheel 426 again presses the push bar 422, and the push bar 422 is prevented from moving further.

Then, the control section 71 controls the elevating mechanism 2 to move to a position corresponding to the N (N e 2, 5) th position coordinate such that the N-th material pipe 32 is opposed to the pusher 422c of the pusher bar 422 from the bottom up in the magazine 3, and at the same time, displays the position coordinate corresponding to the position of the elevating mechanism 2 at this time in the coordinate display area 642f of the status display control screen 642, and then repeats the above-described single-material pipe feeding and resetting process until the start position judgment section 67 n+1th (6 th in this embodiment) judges that the pusher bar 422 is at the start position, the event record storage section 72 stores the current time as the shortage information, while the control section 71 controls the elevating mechanism 2 to move to a position corresponding to the 1 st position coordinate, that is, to the origin position, such that the operator can take the magazine 3 on the elevating mechanism 2 off, and replace the magazine 3 with a new one in which the chip socket is stored.

When the operator presses the stop button 642b to determine that the loading is stopped, the control unit 77 immediately controls the drive motor to stop operating, and further, the control unit 70 also controls the reset cylinder 443 to stop operating immediately, and at this time, when the lifting mechanism 2 is lifting, the control unit 71 controls the lifting mechanism 2 to stop moving.

When the operator presses the stop button 642b and then presses the reset button 642c, the control unit 70 controls the reset cylinder 443 to retract the push rod 422.

The timeout period storage section 73 stores a predetermined time for determining the occurrence of the feeding of the card stock when the pusher 422 pushes the chip socket.

When the control section 77 starts the driving motor to drive the pusher bar pushing chip receptacle, the single pushing timer section 74 counts time and acquires the corresponding time as the current pushing time, the timeout judgment section 75 continuously judges whether the current pushing time is greater than the feeding scheduled time stored in the timeout time storage section 73, and once judged yes, the control section 77 controls the driving motor to stop working, and at the same time, the alarm section 76 gives an alarm, and the input display section 65 displays an alarm screen 644, and the event record storage section 72 stores the current time as alarm information.

The alarm portion 76 is a warning light provided on the housing, and in this embodiment, when the timeout determining portion 75 determines that the current push time is longer than the predetermined feeding time, the warning light is turned on to remind the operator that the feeding device 10 is stuck.

Once the end position determination unit 68 determines that the push bar 422 is at the end position, the single push timer unit 74 clears the current push time.

Example operation and Effect

According to the feeding system for the chip socket, as the pushing mechanism is provided with the pushing strip and the advancing unit for pushing the pushing strip, the chip socket is stored in the material pipe, when an operator selects to start through the state display control picture, the control part starts the advancing unit to drive the pushing strip to push the chip socket to feed, so that the chip socket only moves linearly along the length direction of the material pipe, and the situations of side turning and material clamping of the chip socket caused by vibration feeding of the vibration feeding table can be effectively avoided.

According to the feeding system for the chip socket, since the feeding control device is provided with the starting position judging part and the ending position judging part, the control part controls the advancing unit to push the chip socket, when the ending position judging part judges that the pushing strip is positioned at the ending position, namely, when all the chip sockets in the front material pipe are pushed to the feeding end, the control part controls the advancing unit to stop working, meanwhile, the control part controls the reset cylinder to push the push rod to retract the pushing strip, and when the starting position judging part judges that the pushing strip is positioned at the starting position, the control part controls the reset cylinder to release the push rod, so that the pushing strip is kept at the starting position. The chip socket is pushed to move in the material pipe in a pushing mode, the situations of rollover and clamping of the chip socket caused by vibration feeding of the vibration feeding table can be effectively avoided, and meanwhile automatic pushing of the chip socket is realized through the starting position judging part and the ending position judging part.

According to the feeding system for the chip sockets, the N material pipes are arranged in the magazine, after the pushing strip completes pushing of the chip sockets in one material pipe, the starting position judging part judges that the pushing strip returns to the starting position, the control part controls the lifting mechanism to move so that the next material pipe is aligned with the pushing strip, and accordingly switching of the material pipes is achieved, and after switching is completed, the control part controls the pushing strip to continue pushing of the chip sockets until all the chip sockets in the material pipes are pushed to the feeding end. Therefore, the chip socket loading can be carried out for a long time by installing the magazine once without frequently replacing the magazine, and the loading speed is improved.

In addition, after the starting position judging part judges that the pushing strip is positioned at the starting position for the (n+1) th time, namely the feeding device finishes pushing the chip sockets in all the feeding pipes, the event record storing part stores the current time as the material shortage information, so that an operator can conveniently confirm the material shortage time. Meanwhile, the control part also controls the lifting mechanism to move to a position corresponding to the first position coordinate, namely to return to the initial position, so that an operator can conveniently replace the magazine, take off the empty magazine, and replace the magazine with a new magazine stored with the chip socket, thereby continuing to feed.

According to the feeding system for the chip socket, the single pushing timing part is arranged, so that the current pushing time is obtained by starting timing when the starting position judging part judges that the pushing strip is positioned at the starting position, the timing is stopped when the ending position judging part judges that the pushing strip is positioned at the ending position, the overtime judging part judges whether the current pushing time is larger than the feeding preset time, and when the judgment is yes, the control part controls the advancing unit to stop working when the material is blocked, so that the feeding can be effectively stopped when the material is blocked, damage to the advancing unit due to the blocked material is avoided, and the feeding safety is improved.

In addition, when the material is blocked, the alarm part gives an alarm, and the input display part displays an alarm picture to prompt an operator to block the material, so that the operator can immediately obtain the material blocking information of the feeding device and immediately process the material blocking information, and the production efficiency is improved.

In addition, when the card material occurs, the event record storage part also stores the time of the card material as alarm information, and when an operator selects an event record picture to check the stored record, all alarm information that the feeding device has occurred can be obtained, so that the operator can check and maintain the feeding device conveniently.

According to the feeding system for the chip socket, an operator can set the moving speed of the pushing strip on the parameter setting picture, so that the feeding speed of the feeding device can be considered to be regulated and controlled, and the feeding system is suitable for chip inserting machines or chip attaching machines with different specifications.

The above examples are only for illustrating the specific embodiments of the present invention, and the present invention is not limited to the description scope of the above examples.

In the above embodiment, the alarm portion may be provided in a speaker, and when the timeout determination portion determines that the current push time is longer than the predetermined feeding time, the speaker may give a buzzer to prompt the operator to cause jamming.

In addition, when the alarm portion is an indicator lamp, the indicator lamp may include a plurality of indicator lamps of different colors, for example, in a normal operation state, a green indicator lamp is normally on, when the timeout judging portion judges that the current push time is longer than the feeding predetermined time, that is, when the jam occurs, the green indicator lamp is off, a red indicator lamp is on, when the event record storing portion 72 stores the material shortage information, the green indicator lamp is off, and an orange indicator lamp is on.

In the above embodiment, the number of the tubes in the magazine may be set according to actual needs, for example, considering the overall size and weight of the feeding device, the size and weight of the magazine, and the speed of pushing the chip socket, a tube number is selected that can ensure that the chip socket is continuously pushed and the overall weight is not excessively heavy.
