Description

Technical Field

[0001] The invention relates to the technical field of bending processing, and in particular to a single-chip microcomputer pin bending device. Background Art

[0002] A single-chip microcomputer is an integrated circuit chip that uses very large-scale integrated circuit technology to integrate a central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, multiple I / O ports and interrupt systems, timers / counters and other functions into a small and complete microcomputer system on a silicon chip. It is widely used in the field of industrial control. The pins are connected to peripheral circuits and can detect signal input and output. In compact circuit design, pin bending can save space and make the circuit board layout more reasonable. Therefore, the pins need to be bent during the production process of the single-chip microcomputer.

[0003] In the prior art, a device for bending microcontroller pins with publication number CN112872232B solves the inconvenience of manually transmitting the microcontroller by using a conveying component, shortens the time of transporting the microcontroller, and the conveying component can continuously transport the microcontroller; through the bending mechanism, the manual bending process of the microcontroller pins is eliminated, making the processing of the microcontroller pins more precise, saving manpower while enhancing the accuracy of the product.

[0004] Although the above-mentioned device can improve the bending efficiency of the device, there are still some defects in the actual processing process. Since the discharging end of the bending device lacks a collection mechanism, the microcontroller and pins that have been bent fall directly into the collection box. The falling and collection process not only easily damages the bent pins of the microcontroller, but also makes them messy and disorderly, which is not conducive to the subsequent processing of the microcontroller.

DETAILED DESCRIPTION

[0030] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.

[0031] like Figure 1-10As shown, the present invention provides a single-chip microcomputer pin bending device, including a processing table 1, an L-shaped fixing block 2 is fixedly connected to the top of the processing table 1, and a bending mechanism 3 for bending the single-chip microcomputer pins is provided on the processing table 1 and above the L-shaped fixing block 2. The bending mechanism 3 is mainly composed of a bending head, a driving member, a shielding head and other structures, and because two lower grooves 12 are provided on the device, two bending stations are provided, and the double-row pins of the single-chip microcomputer can be bent one by one. This is a mature technology in the prior art and will not be described in detail here. A loading frame 4 connected to a vibrating loading tray is fixedly connected to the top of the processing table 1, and an L-shaped pushing block 5 is provided between the loading frame 4 and the L-shaped fixing block 2. The top of the processing table 1 and the L-shaped pushing block 5 are located An upper electric telescopic cylinder 6 is fixedly connected to the rear side, and the output end of the upper electric telescopic cylinder 6 is fixedly connected to the side wall of the L-shaped push block 5. Through the arrangement of the upper electric telescopic cylinder 6 and the L-shaped push block 5, it is convenient to push out the single-chip microcomputer in the loading frame 4. A sorting plate 7 is provided at the top of the processing table 1 and is located next to the L-shaped fixed block 2. A plurality of sorting grooves 8 are equidistantly provided at the top of the sorting plate 7. A loading plate 9 is provided on the front side of the L-shaped fixed block 2. A side plate 10 is fixedly connected to the side of the loading plate 9 close to the sorting plate 7. An upper groove 11 is provided on the rear side of the side plate 10. A pair of lower grooves 12 are provided on the rear side of the loading plate 9. A driving mechanism for driving the loading plate 9 to move along a specified route is provided on the processing table 1. A through groove is provided at the top of the processing table 1 and is located below the sorting plate 7;

[0032] A lower electric telescopic cylinder 13 is fixedly connected to the top of the processing table 1, and a pair of clamping plates 14 are provided at the top of the feeding plate 9. Clamping grooves 15 are provided on the rear sides of the clamping plates 14, and a connecting plate 16 is fixedly connected between the front sides of the clamping plates 14. The output end of the lower electric telescopic cylinder 13 is fixedly connected to the side wall of the connecting plate 16. Through the arrangement of the lower electric telescopic cylinder 13 and the clamping plate 14, it is convenient to clamp the single-chip microcomputer on the L-shaped fixed block 2 before the feeding plate 9 releases the single-chip microcomputer, ensuring that the single-chip microcomputer will not fall when the feeding plate 9 is removed;

[0033] The driving mechanism includes a feeding electric telescopic cylinder 17, a groove 18 is provided at the top of the processing table 1, and a pair of transverse grooves 19 and a pair of vertical grooves 20 are provided at the bottom of the groove 18. It should be noted that the length of the transverse groove 19 is the same as the spacing between the lower grooves 12, and the spacing between the upper groove 11 and the lower groove 12 is the same as the spacing between the lower grooves 12, and the vertical grooves 20 are respectively arranged at both ends of the transverse groove 19 and are connected thereto. A sliding frame 21 is slidably connected to the top of the processing table 1, and a slide plate 22 is slidably connected to the inner side of the sliding frame 21. The slide plate 22 is fixedly connected to the bottom end of the feeding plate 9, and a circular groove is provided at the bottom of the slide plate 22. A round rod 23 is slidably connected to the inner side of the circular groove, and the bottom of the round rod 23 is inserted into the inner side of one of the transverse grooves 19. The feeding electric telescopic cylinder 17 is fixedly connected to the inner side of the through groove, and the output end of the feeding electric telescopic cylinder 17 is fixedly connected to a right-angle block 24 with an inclined surface through the groove 18. A plurality of pulling springs 25 are fixedly connected between the inner side of the sliding frame 21 and the slide plate 22. An upper clamping groove 26 is provided at the bottom end of the transverse groove 19 near the side of the L-shaped fixed block 2, and the upper clamping groove 26 is arranged on the side near the feeding frame 4. Through the arrangement of the upper clamping groove 26, the sliding of the round rod 23 in the transverse groove 19 can be limited.

[0034] An upper spring 27 is fixedly connected between the inner side of the circular groove and the top of the round rod 23, and the upper spring 27 facilitates the round rod 23 to be pushed into the upper clamping groove 26 and the lower clamping groove 30, ensuring that the loading plate 9 runs stably along the set route. A moving plate 28 is fixedly connected to the bottom of the sliding frame 21, and the moving plate 28 is slidably connected to the inner side of the groove 18. A pair of lower springs 29 are fixedly connected between the side wall of the groove 18 and the side wall of the moving plate 28, and the lower spring 29 facilitates the loading plate 9 to be pushed to reset. The bottom end of the round rod 23 is set to a smooth arc surface, which makes it easier for the round rod 23 to slide out from the inclined surface of the upper clamping groove 26 more smoothly, and the outer wall of the round rod 23 contacts the inclined surface of the right-angle block 24, and the connection between the upper clamping groove 26 and the transverse groove 19 is inclined.

[0035] In the process of bending the pins of the single-chip microcomputer, the single-chip microcomputer is first poured into the vibrating loading tray. Under the arrangement of the vibrating loading tray, the single-chip microcomputer will be neatly discharged from the loading frame 4, and then gradually moved to the L-shaped push block 5, and then the upper electric telescopic cylinder 6 is controlled to start pushing the L-shaped push block 5 to move, and then the single-chip microcomputer is pushed into one of the lower grooves 12 of the loading plate 9, and then the control 17 can be started to drive the right-angle block 24 to move (the round rod 23 in the initial position is located on the inner side of the upper card slot 26). Since there is a step between the upper card slot 26 and the vertical slot 20, it is restricted. Therefore, when the right-angle block 24 is moved away, the sliding frame 21 will be on the lower spring 29. The elastic force pushes down to reset, and drives the feeding plate 9 to move, pushing the single-chip microcomputer from the L-shaped push block 5 to the L-shaped fixed block 2. At the same time, it drives the round rod 23 to slide out from the inclined surface on the upper clamping groove 26 and into the transverse groove 19, and gradually compresses the upper spring 27, thereby pushing the single-chip microcomputer to the bottom of the bending mechanism 3. After reaching the specified position, the round rod 23 also moves to the other end of the transverse groove 19. At this time, the round rod 23 will touch the upper touch sensor 33, and then the upper electric telescopic cylinder 6 can be controlled to start and drive the L-shaped push block 5 to reset. At this time, under the output of the vibrating feeding tray, the single-chip microcomputer on the feeding frame 4 will continue to move to the L-shaped push block 5;

[0036] Then, the controller controls the lower electric telescopic cylinder 13 to start and drive the connecting plate 16 and the clamping plate 14 to move, and the single-chip microcomputer is quickly clamped by the clamping groove 15. At the same time, the feeding electric telescopic cylinder 17 continues to move, and the right-angle block 24 is driven to move away from the round rod 23, thereby gradually releasing the squeezing of the round rod 23. At the same time, the round rod 23 moves to the side of the vertical groove 20, so that the slide plate 22 is pulled to reset under the elastic force of the pulling spring 25, and the round rod 23 is driven to slide in the vertical groove 20, so that the round rod 23 slides into another horizontal groove 19. At the same time, the feeding plate 9 is removed from the single-chip microcomputer. At this time, the round rod 23 is located above the positioning groove 43, and then the round rod 23 is pushed into the positioning groove 43 under the elastic force of the upper spring 27.

[0037] Then the bending mechanism 3 can be controlled to start, the microcontroller pins can be bent, and the feeding electric telescopic cylinder 17 can be controlled to move in the opposite direction for resetting. Since there is a step between the positioning groove 43 and the vertical groove 20 and it is restricted, the rectangular block 31 on the right-angle block 24 will be driven to move to the side of the round rod 23, and then the round rod 23 will be squeezed by the rectangular block 31 to move, so that the round rod 23 slides out of the positioning groove 43, and the feeding plate 9 is driven to move at the same time, and then the round rod 23 slides to the other end of the horizontal groove 19, and the lower spring 29 is compressed, and it is located above the lower card slot 30, so that it is pushed in under the elastic force of the upper spring 27, and at the same time the rectangular block 31 moves to the moving groove 32, and through the continued movement of the right-angle block 24, the round rod 23 will be gradually squeezed by the inclined surface of the right-angle block 24 to slide along the vertical groove 20, and then slide out of the lower card slot. 30 slides into the upper slot 26 and stretches the pulling spring 25, thereby resetting the feeding plate 9. At the same time, another lower slot 12 on the feeding plate 9 is inserted into the single-chip microcomputer pushed to the specified position below the bending mechanism 3. Then, the upper electric telescopic cylinder 6 is controlled to start by the upper touch sensor 33. This is repeated to achieve automatic feeding and bending of the single-chip microcomputer. After the single-chip microcomputer is bent twice, the single-chip microcomputer will continue to be pushed to the side close to the sorting plate 7 under the continued driving of the feeding plate 9. Then, the single-chip microcomputer that has been bent will be inserted into the upper slot 11 on the side plate 10 under the repeated driving of the feeding plate 9. Therefore, under the push of the feeding plate 9, the single-chip microcomputer will be moved out from the L-shaped fixing block 2 and pushed into the sorting slot 8 on the sorting plate 7. This can be repeated to arrange the single-chip microcomputer in the sorting slot 8 for subsequent production and processing.

[0038] The upper end of the right-angle block 24 is fixedly connected to the rectangular block 31, and the outer wall of the round rod 23 is provided with a movable groove 32 located above the rectangular block 31, so that when the round rod 23 moves into the horizontal groove 19 away from the side of the L-shaped fixed block 2, the round rod 23 is pushed to move, thereby avoiding the inclined surface of the right-angle block 24 from squeezing the round rod 23 to slide, making the process of pushing the round rod 23 to slide more smoothly, and when the round rod 23 slides above the lower groove 30 and is pushed in by the elastic force of the upper spring 27, the movable groove 32 on the outer wall of the round rod 23 will move to the side of the rectangular block 31, and the inclined surface of the right-angle block 24 will move to the side of the round rod 23, so that the round rod 23 is squeezed to slide downward by the continued movement of the right-angle block 24, and the rectangular block 31 is inserted in the movable groove 32, which will not affect the normal sliding of the round rod 23;

[0039] A positioning groove 43 is provided at the bottom of the transverse groove 19 on the side away from the L-shaped fixed block 2, and the positioning groove 43 is arranged on the side away from the loading frame 4. The connection between the positioning groove 43 and the transverse groove 19 is inclined. Through the setting of the positioning groove 43, the sliding of the round rod 23 can be limited. It should be noted here that the depth of the lower groove 30 is deeper than the depth of the positioning groove 43, and the depth of the upper groove 26 is deeper than the depth of the lower groove 30. When the round rod 23 moves into the positioning groove 43, the rectangular block 31 will not be inserted into the movable groove 32, and will squeeze the outer wall of the round rod 23 to drive it to slide.

[0040] In order to improve the automation degree of the device, upper touch sensors 33 are fixedly connected to both sides of the bottom of the horizontal groove 19 near the side of the L-shaped fixed block 2, and the upper touch sensor 33 near the side of the sorting plate 7 is electrically connected to the lower electric telescopic cylinder 13 through the controller. When the loading plate 9 drives the single-chip microcomputer to move into place, the round rod 23 will touch the corresponding upper touch sensor 33, and then transmit the signal to the controller. The controller controls the lower electric telescopic cylinder 13 to start, drive the connecting plate 16 and the clamping plate 14 to clamp the single-chip microcomputer, and then continue to drive the loading electric telescopic cylinder 17 to release the squeeze on the round rod 23, and the loading plate 9 will be pulled out under the elastic force of the pulling spring 25;

[0041] At the same time, the upper touch sensor 33 close to one side of the loading frame 4 is electrically connected to the upper electric telescopic cylinder 6 through the controller. When the loading plate 9 moves to the corresponding position, the round rod 23 will touch the corresponding upper touch sensor 33, and then transmit the signal to the controller. The controller controls the upper electric telescopic cylinder 6 to start and drive the L-shaped push block 5 to move out, and then push the single-chip microcomputer on the loading frame 4 into the lower groove 12, thereby realizing the automatic operation of the device.

[0042] In order to ensure that the side panel 10 pushes the single chip microcomputer into the sorting slot 8, a notch 34 is provided on the side of the sorting plate 7 close to the L-shaped fixing block 2, and the bottom of the notch 34 is flush with the bottom of the side panel 10. The notch 34 is provided to avoid obstruction to the normal operation of the side panel 10.

[0043] In order to automatically drive the sorting plate 7 to move when the sorting slots 8 on the sorting plate 7 are full, a lower plate 35 is fixedly connected to the top of the processing table 1 and located next to the through slot, a pair of transmission rollers 36 are rotatably connected between the lower plate 35 and the inner side of the processing table 1, and a conveyor belt 37 is transmission-connected between the transmission rollers 36, a driving motor 38 is fixedly connected to the side wall of the lower plate 35, and the output end of the driving motor 38 passes through the lower plate 35 and is fixedly connected to the side wall of one of the transmission rollers 36, a pair of plug blocks 39 are equidistantly fixedly connected to the outer wall of the conveyor belt 37, and a slot 40 adapted to the plug block 39 is provided at the bottom of the sorting plate 7;

[0044] The side wall of the processing table 1 is fixedly connected with a baffle 41, and the side wall of the baffle 41 is penetrated and fixedly connected with a lower touch sensor 42, and the lower touch sensor 42 is electrically connected to the driving motor 38 through the controller. It should be noted that the lower touch sensor 42 is a press-type touch sensor. When the single-chip microcomputer touches it, the protruding part will be squeezed in, so as not to affect the normal movement of the finishing plate 7;

[0045] With the continuous operation of the feeding mechanism, the side wall of the side plate 10 will continuously push the single-chip microcomputer into the sorting groove 8. When the single-chip microcomputer in the sorting groove 8 is fully collected, the single-chip microcomputer in the sorting groove 8 will touch the lower touch sensor 42, and then the lower touch sensor 42 will transmit the signal to the controller. The controller controls the drive motor 38 to start and drive one of the transmission rollers 36 to rotate, and then the transmission conveyor belt 37 is transported between the two transmission rollers 36, and at the same time drives the other transmission roller 36 to rotate. Since the insert block 39 is inserted in the slot 40 under the sorting plate 7, it will push the sorting plate 7 to move at the same time (it should be noted here that the running time of the drive motor 38 each time can be set by the program to ensure that the next sorting groove 8 is accurately pushed to the position corresponding to the side plate 10), thereby realizing automatic position change of the device and further improving the convenience of the device.

[0046] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention.
