Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, and more specifically, to a capacitor pin riveting device. Background Technology

[0002] A capacitor consists of two conductors placed close together, with a non-conductive insulating medium sandwiched between them. When a voltage is applied between the two plates, the capacitor stores electrical charge. The capacitor manufacturing process includes cutting, winding, impregnation, assembly, aging, sealing, printing, sheathing, measurement, packaging, and inspection. During production, the capacitor's leads need to be riveted together. This involves extending the electrodes and then riveting the leads to the positive and negative aluminum foil. The quality of this riveting directly determines the final quality of the aluminum electrolytic capacitor.

[0003] A search revealed that Chinese patent application CN202321395704.4 discloses a capacitor pin riveting device, relating to the field of capacitor production. The device includes aluminum foil, a pin, a U-shaped plate, and a riveting table. The riveting table is fixedly mounted on the lower inner wall of the U-shaped plate. A first square opening for the pin to pass through is provided on the front side of the riveting table. Second square openings for the aluminum foil to pass through are provided on the lower ends of both sides of the first square opening. A circular groove is provided in the lower center of the first square opening, and a first riveting mechanism is provided inside the groove. A circular opening vertically aligned with the groove is provided in the upper center of the first square opening, and a clamping mechanism for fixing the pin and aluminum foil is also provided on the upper inner wall of the first square opening. This utility model can simultaneously press and fix the aluminum foil and guide pin after placement, and does not require disassembly after punching, allowing for direct riveting to connect the aluminum foil and guide pin, thus improving work efficiency and preventing misalignment of the punched holes, thereby improving riveting quality. However, it still has the following drawbacks:

[0004] (1) The riveting device in the prior art requires manual fixing of aluminum foil and guide pin, resulting in low riveting efficiency. At the same time, it is difficult to align the guide pin and aluminum foil, and it is easy to deviate. In addition, during the punching process, the waste residue that falls off the punching device enters the first riveting plate, affecting the subsequent riveting operation and making it inconvenient to collect the waste generated by punching.

[0005] Existing riveting devices require manual insertion of rivets into the punch holes, which is inconvenient for automated rivet feeding, resulting in low automation and low riveting efficiency.

[0006] Therefore, we have made improvements to this by proposing a capacitor guide pin riveting device. Summary of the Invention

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] like Figures 1-9As shown, this embodiment proposes a capacitor guide pin riveting device, including a base plate 1. Four mounting posts 2 are uniformly fixedly connected to the upper end face of the base plate 1. The mounting posts 2 are detachably connected to a mounting plate 3 by screws. A riveting frame 4 is fixedly connected to the left end of the upper end face of the mounting plate 3. An aluminum foil 5 is placed inside the riveting frame 4. A clamping mechanism 6 for clamping the aluminum foil 5 is provided inside the riveting frame 4. A collecting mechanism 7 is provided on the lower side of the riveting frame 4. Two mounting seats 8 are symmetrically and fixedly connected to the upper end face of the mounting plate 3. A rotating shaft 9 is rotatably connected between the two mounting seats 8. An assembly block 10 is fixedly connected to the rotating shaft 9. A parallel cylinder 11 is fixedly connected to the assembly block 10. A clamping bracket 12 is fixedly connected to each of the two driving ends of the parallel cylinder 11. A guide pin body 13 is placed inside the clamping bracket 12. A device for clamping the guide pin body 13 is provided on the mounting plate 3. The parallel cylinder 11 is used to flip the mechanism 14. The mounting plate 3 is provided with a rivet feeding mechanism 15 on the lower side. The upper left end of the base plate 1 is rotatably connected to the support shaft 16. The top end of the support shaft 16 is fixedly connected to the top plate 17. The end of the top plate 17 away from the support shaft 16 is rotatably connected to the connecting shaft 18. The bottom end of the connecting shaft 18 is fixedly connected to the connecting plate 19. The top plate 17 is provided with a shifting mechanism 20 for driving the connecting plate 19 to shift. The riveting frame 4 and the clamping mechanism 6 facilitate the positioning and clamping of the aluminum foil 5. The parallel cylinder 11 drives the clamping frame 12 to move inward or outward at the same time, thereby clamping and contacting the guide needle body 13. There is no need for manual fixation of the aluminum foil 5 and the guide needle body 13. The degree of automation is high and the riveting efficiency is improved.

[0038] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the clamping mechanism 6 further includes two movable openings 601 symmetrically opened on the rear side wall of the riveting frame 4. A slider 602 is slidably connected to each of the two movable openings 601. A clamping plate 603 is fixedly connected to the inner end of the slider 602, and a connecting rod 604 is rotatably connected to the outer end of the slider 602. A connector 605 is rotatably connected between the outer ends of the connecting rods 604. A support 606 is fixedly connected to the mounting plate 3, and a first cylinder 607 is fixedly connected to the support 606. The driving end of the first cylinder 607 is fixedly connected to the support 606. The first cylinder 607 drives the connector 605 to move, and the connector 605 pulls the slider 602 to slide within the movable opening 601 via the connecting rod 604, thereby driving the clamping plate 603 to move within the riveting frame 4, realizing the clamping or releasing of the aluminum foil 5, facilitating automated clamping and fixing of the aluminum foil 5.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, in a preferred embodiment, based on the above method, the collecting mechanism 7 further includes a collecting box 701 disposed within the riveting frame 4. Two connecting pieces 702 are symmetrically and fixedly connected to the lower front end of the collecting box 701. A moving opening matching the connecting pieces 702 is provided on the mounting plate 3. Two fixing pieces 703 are symmetrically and fixedly connected to the lower end of the mounting plate 3. A second cylinder 704 is fixedly connected to each of the two fixing pieces 703. The driving end of the second cylinder 704 is fixedly connected to the connecting piece 702. The collecting box 701 can collect waste material during the punching process. The second cylinder 704 drives the collecting box 701 to move on the mounting plate 3, thereby removing the collecting box 701 and avoiding interference with the feeding and riveting of the rivets.

[0040] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the flipping mechanism 14 further includes a first gear 1401 fixed to the rear end of the rotating shaft 9. A guide rail 1402 is provided on the lower side of the first gear 1401. The guide rail 1402 is fixedly connected to the mounting plate 3. A slide bar 1403 is slidably connected inside the guide rail 1402. A rack 1404, meshing with the first gear 1401, is fixedly connected to the upper end face of the slide bar 1403. A support plate 1405 is fixedly connected to one end of the rack 1404. The mounting plate 3... A telescopic cylinder 1406 is fixedly connected to the upper end face of the device. The driving end of the telescopic cylinder 1406 is fixedly connected to the support plate 1405. The telescopic cylinder 1406 drives the support plate 1405 to move, which in turn drives the rack 1404 to slide in the guide rail 1402. Since the rack 1404 is meshed with the first gear 1401, the movement of the rack 1404 drives the first gear 1401 to rotate, thereby rotating the rotating shaft 9 and realizing the flipping of the parallel cylinder 11, which facilitates the feeding of the guide needle and ensures that the guide needle and the aluminum foil 5 are accurately aligned.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, the rivet feeding mechanism 15 further includes a rivet vibratory feeder 1501 fixed on the base plate 1. A guide frame 1502 is installed at the output port of the rivet vibratory feeder 1501. A bearing frame 1503 is provided at the output port of the guide frame 1502. The bearing frame 1503 is fixedly connected to the base plate 1 via a fixing post 1504. A push plate 1505 is slidably connected inside the bearing frame 1503. A first connecting part 1506 is fixedly connected to one end of the bearing frame 1503. A third cylinder 150 is fixedly connected to the first connecting part 1506. 7. A connecting strip 1508 is fixedly connected to the drive end of the third cylinder 1507. The connecting strip 1508 is fixedly connected to the push plate 1505. A round opening is provided at the other end of the bearing frame 1503, and a lifting seat 1509 is provided inside the round opening. A second connecting part 1510 is fixedly connected to the lower end face of the bearing frame 1503 near the lifting seat 1509. A fourth cylinder 1511 is fixedly connected to the second connecting part 1510. The drive end of the fourth cylinder 1511 is fixedly connected to the lifting seat 1509. An avoidance opening 1512 is provided on the bearing frame 1503, and an opening is provided on the push plate 1505. The lifting seat 1509 has a mating part 1513 that matches the rivet, and a groove that mates with the mating part 1513 is provided on the upper end face of the lifting seat 1509. The rivet vibratory feeder 1501 transports the rivets in an orderly manner to the guide frame 1502, then into the bearing frame 1503, and then into the opening space of the push plate 1505. The third cylinder 1507 drives the connecting bar 1508 to move the push plate 1505 to slide within the bearing frame 1503, pushing the rivet into the lifting seat 1509. Then, the third cylinder 1507 retracts to reset the push plate 1505, and the fourth cylinder 1511 drives the lifting seat 1509 to rise. The rivet is fed into the punch holes of the aluminum foil 5 and the guide pin body 13, realizing automated rivet feeding. This enables continuous and stable rivet supply, improves riveting efficiency, reduces manual intervention, and lowers labor intensity. The clearance opening 1512 facilitates the rivet entering the bearing frame 1503. The mating part 1513 is used to accommodate the rivet and ensures the stability of the rivet during the push of the push plate 1505. The groove on the lifting seat 1509 causes the rivet pushed into it to sink, thereby separating the top of the rivet from the mating part 1513, which in turn facilitates the reset of the push plate 1505.

[0042] like Figure 6 and Figure 7As shown, in a preferred embodiment, based on the above method, a punching cylinder 21 is fixedly connected to the front end of the lower end face of the connecting plate 19, a punching head 22 is fixedly connected to the driving end of the punching cylinder 21, a riveting cylinder 23 is fixedly connected to the rear end of the lower end face of the connecting plate 19, and a riveting plate 24 is fixedly connected to the driving end of the riveting cylinder 23. The punching cylinder 21 and the punching head 22 facilitate punching of the aluminum foil 5 and the guide needle body 13, and the riveting cylinder 23 and the riveting plate 24 facilitate riveting of the aluminum foil 5 and the guide needle body 13.

[0043] like Figure 1 and Figure 8 As shown, in a preferred embodiment, based on the above method, the shifting mechanism 20 further includes a second gear 2001 fixed on the connecting shaft 18, a first motor 2002 fixedly connected to the upper end surface of the top plate 17, and a third gear 2003 meshing with the second gear 2001 through the driving end of the first motor 2002. The first motor 2002 drives the third gear 2003 to rotate. Since the third gear 2003 meshes with the second gear 2001, the rotation of the third gear 2003 drives the second gear 2001 to rotate, thereby rotating the connecting shaft 18 and realizing the shifting of the connecting plate 19. This allows the punching cylinder 21 and the riveting cylinder 23 to be shifted, thus facilitating punching and riveting operations.

[0044] like Figure 2 As shown, in a preferred embodiment, based on the above method, a worm gear 25 is fixedly connected to the bottom of the support shaft 16, a mating plate 26 is fixedly connected to the base plate 1, a second motor 27 is fixedly connected to the mating plate 26, and the driving end of the second motor 27 passes through the mating plate 26 and is fixedly connected to a worm 28 that meshes with the worm gear 25; the second motor 27 drives the worm 28 to rotate, and the rotation of the worm 28 drives the worm gear 25 to rotate, thereby rotating the support shaft 16 and realizing the rotation of the top plate 17, further adjusting the position of the punching cylinder 21 and the riveting cylinder 23 to avoid interference with the placement of the guide pin.

[0045] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a placement frame 29 matching the clamp 12 is fixedly connected to the right end of the upper surface of the mounting plate 3, and a limiting block 30 is fixedly connected to the left end of the upper surface of the placement frame 29; the placement frame 29 facilitates the placement of the guide needle, thereby facilitating the clamp 12 to clamp the guide needle, and the limiting block 30 facilitates limiting the position of the guide needle.

[0046] like Figure 4 and Figure 9As shown, in a preferred embodiment, based on the above method, the bottom of the riveting frame 4 is provided with a first through hole 31 corresponding to the lifting seat 1509, and the mounting plate 3 is provided with a second through hole 32 corresponding to the first through hole 31; when the lifting seat 1509 rises, the rivet can reach the designated position through the first through hole 31 and the second through hole 32, which facilitates the riveting operation.

[0047] Specifically, in use, this capacitor pin riveting device works as follows: First, the second motor 27 drives the worm gear 28 to rotate. The rotation of the worm gear 28 drives the worm wheel 25 to rotate, thereby rotating the support shaft 16 and realizing the rotation of the top plate 17. This rotates the punching cylinder 21 and the riveting cylinder 23 to the upper side away from the riveting frame 4. Then, the parallel cylinder 11 is flipped onto the placement frame 29. Next, the aluminum foil 5 is placed in the riveting frame 4. The first cylinder 607 drives the connector 605 to move. The connector 605 pulls the slider 602 to slide within the moving opening 601 via the connecting rod 604. The clamping plate 603 moves within the riveting frame 4 to clamp the aluminum foil 5, placing the guide needle body 13 on the placement frame 29. Then, the parallel cylinder 11 drives the clamping frame 12 to clamp the guide needle body 13. The telescopic cylinder 1406 then moves the support plate 1405, causing the rack 1404 to slide within the guide rail 1402. Since the rack 1404 is meshed with the first gear 1401, the movement of the rack 1404 causes the first gear 1401 to rotate, thus rotating the rotating shaft 9. This causes the parallel cylinder 11 to flip, transferring the guide needle body 13 to its new position. Figure 1 The position is then adjusted, and the second motor 27 is driven to rotate the support shaft 16 and the top plate 17 to the desired position. Figure 1 The punching cylinder 21 drives the punching head 22 to descend and punch the aluminum foil 5 and the guide needle body 13. During punching, the waste falls into the collection box 701. Then, the second cylinder 704 drives the collection box 701 to move forward, thus exposing the first through hole 31 and the second through hole 32. At the same time, the first motor 2002 drives the third gear 2003 to rotate. Since the third gear 2003 is meshed with the second gear 2001, the rotation of the third gear 2003 drives the second gear 2001 to rotate, thereby rotating the connecting shaft 18, realizing the repositioning of the connecting plate 19, and causing the punching cylinder 21 and the riveting cylinder 23 to reposition. The rivet vibratory feeder 1501 transports the rivets in an orderly manner to the guide frame 1502, then into the bearing frame 1503, and then into the opening space of the push plate 1505. The third cylinder 1507 drives the connecting bar 1508 to move the push plate 1505 within the bearing frame 1503, pushing the rivets into the lifting seat 1509. Then the third cylinder 1507 retracts to reset the push plate 1505. The fourth cylinder 1511 drives the lifting seat 1509 to rise, sending the rivets into the punch holes of the aluminum foil 5 and the guide needle body 13. Then the riveting cylinder 23 drives the riveting plate 24 to descend, thereby riveting the rivets and completing the riveting operation.

[0048] All technical features in this embodiment can be freely combined according to actual needs.

[0049] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
