The piston rod end of the first cylinder passes through the bracket and is fixedly mounted on a mounting plate; this fixing connection can also be replaced by bolts or welding. A folding blade is fixedly mounted on the bottom of the mounting plate. This invention, by providing a fixing mechanism, facilitates the clamping and fixing of the aluminum electrolytic capacitor, making it easier to fold the capacitor. The lifting mechanism facilitates the lifting of one end of the aluminum electrolytic capacitor, and the folding blade, together with the fixture, facilitates the folding of the capacitor.

[0004] The aforementioned patent has the following drawbacks: during the folding operation, a large amount of debris is generated due to the material of the aluminum electrolytic capacitor shell and the movement of the folding knife. The debris will fly around at a high speed, posing a threat to the personal safety of the operator. Therefore, a new type of aluminum electrolytic capacitor folding fixture is proposed.

[0030] Example

[0031] Please see Figure 1-6 This utility model provides a technical solution: a novel aluminum electrolytic capacitor folding fixture, including an operating table 1. The top of the operating table 1 is respectively fixed with a knife holder 4, a horizontal plate 6, a first support frame 7 and a second support frame 8. The top of the first support frame 7 is fixed with a second electric push rod 5. The push rod end of the second electric push rod 5 is fixed with a folding knife 11 located on the top of the knife holder 4. The push rod end of the first electric push rod 3 is provided with a pressure plate 9. The bottom of the pressure plate 9 is glued with a rubber plate 10. The top of the horizontal plate 6 is placed with the aluminum electrolytic capacitor shell to be folded. The bottom of the pressure plate 9 is glued with the rubber plate 10. The rubber plate 10 is in contact with the capacitor shell and plays a buffering role during the pressing process to avoid damaging the capacitor shell due to excessive pressure or hard contact. The top of the second support frame 8 is fixed with a first electric push rod 3. The first electric push rod 3 is provided with a protective component 2 for safety protection on one side.

[0032] The protective component 2 includes a ring frame 22 and a disassembly mechanism. A transparent protective cover 21 is fixed on the outside of the ring frame 22, located outside the knife holder 4, the horizontal plate 6 and the folding knife 11. The transparent protective cover 21 moves downward and covers the outside of the knife holder 4, the horizontal plate 6 and the folding knife 11, effectively blocking the flying debris generated during folding, providing reliable safety protection for operators and reducing the probability of workplace accidents.

[0033] The disassembly mechanism includes a fixed frame 23 and a connecting rod 24. A locking groove 28 is provided on one side of the connecting rod 24. A limit groove 29 and a sliding groove 211 are respectively provided inside the fixed frame 23. A limit rod 213 is fixed at the push rod end of the first electric push rod 3. The bottom of the limit rod 213 is fixed to the top of the pressure plate 9. The fixed frame 23 and the connecting rod 24 are made of metal.

[0034] A sliding plate 210 is slidably connected to the inner side of the slide groove 211. A locking rod 27 and a pull rod 212 are fixed to both sides of the sliding plate 210, respectively. The locking rod 27 is cylindrical. When the locking rod 27 is inserted into the inner side of the locking groove 28, the transparent protective cover 21 is in the installed state; when the locking rod 27 is removed from the inner side of the locking groove 28, the transparent protective cover 21 is in the disassembled state. The locking rod 27 and the locking groove 28 are engaged with an H7 / g6 fit. The movement of the locking rod 27 is controlled by pulling the pull rod 212 to slide the sliding plate 210, thus realizing the movement of the transparent protective cover 21. For disassembly and installation, a sliding rod 25 is fixed to the inner wall of the slide 211 and extends through one side of the slide plate 210. A spring 26 is sleeved on the outer side of the sliding rod 25. The two sides of the spring 26 are respectively connected to one side of the slide plate 210 and the slide 211. One side of the fixing frame 23 is fixed to one side of the ring frame 22. The outer side of the pull rod 212 extends through one side of the fixing frame 23. The movement of the locking rod 27 is controlled by the sliding of the slide plate 210 driven by the movable pull rod 212, so as to realize the disassembly and installation of the transparent protective cover 21. The operation is simple and direct.

[0035] Working principle: Place the aluminum electrolytic capacitor shell to be folded on the horizontal plate 6 at the top of the operating table 1. At this time, the capacitor shell is in the processing position. Start the first electric push rod 3 fixed at the top of the second support frame 8. The push rod end of the first electric push rod 3 moves downward, driving the limit rod 213 and the pressure plate 9 fixed at its push rod end to move downward. Since the bottom of the pressure plate 9 is bonded with a rubber plate 10, after the rubber plate 10 contacts the capacitor shell, under the action of the first electric push rod 3, the capacitor shell is pressed on the horizontal plate 6 to prevent displacement during the subsequent folding process. The rubber plate 10 also plays a buffering role to avoid damaging the capacitor shell.

[0036] The second electric push rod 5, fixed at the top of the first support frame 7, is activated. The push rod end of the second electric push rod 5 moves downward, causing the folding blade 11, fixed at its push rod end, to move downward. The folding blade 11 moves above the blade holder 4. When the folding blade 11 contacts the edge of the capacitor shell, it performs folding processing on the edge of the capacitor shell. During the folding operation, the push rod end of the second support frame 8 extends, causing the pressure plate 9 and the transparent protective cover 21 to move downward and cover the outside of the blade holder 4, the horizontal plate 6, and the folding blade 11. The transparent protective cover 21 serves as a safety protection to prevent debris generated during the folding process from flying and injuring people. At the same time, the operator can observe the folding process through the transparent protective cover 21.

[0037] When the transparent protective cover 21 needs to be disassembled for maintenance or cleaning, the operator pulls the lever 212. The lever 212 causes the slide plate 210 to slide in the slide groove 211. Since the inner wall of the slide groove 211 is fixed with a slide rod 25 that moves through one side of the slide plate 210, the slide plate 210 slides on the slide rod 25. At the same time, the spring 26 sleeved on the outside of the slide rod 25 is compressed. The slide plate 210 slides and drives the locking rod 27 to move, so that the locking rod 27 leaves the inside of the locking groove 28 opened on one side of the connecting rod 24. At this time, the transparent protective cover 21 is in a detachable state, and the operator can remove the ring frame 22 and the transparent protective cover 21 from the fixture.

[0038] When the transparent protective cover 21 needs to be installed, place the ring frame 22 in a suitable position so that the connecting rod 24 corresponds to the position of the limiting groove 29. Move the transparent protective cover 21 so that the connecting rod 24 is inserted into the limiting groove 29. Then pull the pull rod 212 and release it. Under the elastic force of the spring 26, the spring 26 pushes the slide plate 210 to slide in the slide groove 211. The slide plate 210 drives the locking rod 27 to insert into the inside of the locking groove 28. At this time, the transparent protective cover 21 is in the installation state, which ensures the stability of the installation of the protective component 2.

[0039] In summary, by pushing the limit rod 213 and the pressure plate 9 downward by the first electric push rod 3, the capacitor shell is pressed onto the horizontal plate 6. The bottom of the pressure plate 9 is bonded with a rubber plate 10, which contacts the capacitor shell and plays a buffering role during the pressing process, avoiding damage to the capacitor shell due to excessive pressure or hard contact, reducing the product damage rate, and reducing material waste and cost losses in the production process.

[0040] During the folding operation, the push rod end of the second support frame 8 extends and drives the transparent protective cover 21 to move downward and cover the outside of the knife holder 4, the horizontal plate 6 and the folding knife 11, effectively blocking the flying debris generated during folding, providing reliable safety protection for operators, reducing the probability of work-related accidents. The transparent protective cover 21 allows operators to observe the folding process during processing, without affecting the monitoring of the processing status, and ensures that operators can operate in a safe environment, making it easier to detect and deal with problems that occur during processing in a timely manner, and improving the safety and controllability of production.

[0041] The movement of the locking rod 27 is controlled by pulling the lever 212 to slide the slide plate 210, thereby realizing the disassembly and installation of the transparent protective cover 21. The operation method is simple and direct, and the operator can quickly master the operation method, which reduces the operation difficulty, improves the work efficiency, and allows maintenance personnel to clean and inspect the transparent protective cover 21 more comprehensively and thoroughly, promptly discover and deal with potential problems, and extend the service life of the transparent protective cover 21.
