[0002] The pre-punched aluminum foil will form the electrodes of the capacitor during the process of making aluminum electrolytic capacitors. The positive electrode is usually made of a bent aluminum strip, while the negative electrode is made of aluminum foil. The necessary holes can be formed on the aluminum foil through the pre-punching process. These holes help the flow of electrolyte and the contact between the electrodes, so that the capacitor can work normally, while maintaining the overall strength of the capacitor, making the capacitor more stable and reliable in practical applications.

[0003] During the pre-punching process of the aluminum foil in the aluminum electrolytic capacitor, when the aluminum foil passes through the punching table, the punching die moves down to directly punch the aluminum foil on the punching table. This method cannot ensure the precise positioning of the aluminum foil during the punching process. This may cause the position, shape and size of the hole to not meet the design requirements, thereby affecting the performance and stability of the capacitor. Since the punching die directly punches the aluminum foil, this method may cause the punching force to be unevenly distributed on the aluminum foil. This may cause the aluminum foil around the hole to deform, crack, etc., affecting the overall quality and stability of the capacitor. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The following is combined with Figure 1-5 To further explain this application in detail,

[0031] The embodiment of the present application discloses an aluminum foil pre-punching positioning platform for aluminum electrolytic capacitor production, comprising a punching platform 1 and a positioning block 5, wherein the four corners of the punching platform 1 are provided with circular mounting grooves 2, wherein a guide rod 3 and a spring 4 sleeved on the outer side of the guide rod 3 are fixedly installed in the circular mounting groove 2;

[0032] The positioning block 5 is sleeved on the outer side of the guide rod 3 and a limit joint 6 is provided on the top of the positioning block 5 and is threadedly connected to the guide rod 3. The positioning block 5 is provided with a concave groove 7 which cooperates with the die head of the upper punching die for guiding and plugging;

[0033] The aluminum foil between the positioning block 5 and the punching table 1 is clamped and positioned by moving the die head of the upper punching die downward to push the positioning block 5 downward toward the punching table 1 .

[0034] The precise positioning function can be realized by combining the positioning block 5 with the circular mounting groove 2, the guide rod 3 and the spring 4 on the punching table 1. The concave groove 7 on the positioning block 5 cooperates with the die head of the upper punching die to guide and plug, ensuring the accurate positioning of the aluminum foil during the punching process and avoiding the deviation or misalignment of the hole position; by moving the die head of the upper punching die downward to push the positioning block 5 downward and approach the punching table 1, the aluminum foil between the positioning block 5 and the punching table 1 can be clamped and positioned. This clamping method ensures the stability of the aluminum foil during the punching process, prevents the change of the position of the aluminum foil, and ensures the consistency and accuracy of the holes; the positioning and clamping process of the aluminum foil is simpler and faster, and the production efficiency is improved. The worker only needs to place the aluminum foil on the positioning block 5, and the positioning and clamping operation can be completed by moving the die head of the upper punching die downward, without the need for complicated adjustment and fixing steps; through precise positioning and stable clamping, the pre-punching positioning table can ensure the accuracy and stability of the position of the aluminum foil during the punching process, thereby ensuring the quality of the final product. The location, size and shape of the holes meet the design requirements, ensuring the performance and stability of the capacitor.

[0035] The aluminum foil pre-punching positioning platform for aluminum electrolytic capacitor production also includes a support 13, which is fixedly connected to the punching platform 1 through four support rods 14 at the four corners of its top, and a slot 16 is provided on the support 13 to cooperate with the waste slot 15.

[0036] The upper end surface of the waste trough 15 contacts the bottom surface of the punching table 1 . The waste trough 15 is provided with a flange 17 resting on the support 13 . The flange 17 is provided with a hand-grip hole 18 .

[0037] The design of the waste trough 15 allows punching waste to be easily collected and processed. The support 13 is provided with a slot 16 that matches the waste trough 15, which can position the waste trough 15 and ensure the stability and reliability of the waste trough 15 during the punching process. The upper end surface of the waste trough 15 contacts the bottom surface of the punching table 1, which can effectively prevent waste from overflowing and leaking, and keep the working area clean and tidy.

[0038] The waste trough 15 is provided with a flange 17 resting on the support 13, and a hand-grip hole 18 is provided on the flange 17, which makes it more convenient to install, disassemble and handle the waste trough 15. Workers can easily grasp the flange 17 through the hand-grip hole 18 to install and disassemble the waste trough 15, thereby improving the convenience of operation.

[0039] The waste trough 15 can collect and centrally process wastes, prevent the wastes from damaging the punching table 1 and the equipment, and reduce the scattering and splashing of wastes, thereby protecting the surrounding environment and the cleanliness of the equipment.

[0040] Two symmetrical guide rails 8 are provided on both sides of the punching station 1, and a guide groove 9 for guiding the feeding of aluminum foil is formed between the two guide rails 8. The bottom of the positioning block 5 is provided with an open groove 10 for the guide rail 8 to penetrate and extend into.

[0041] The guide rail 8 can accurately guide and position the aluminum foil, ensuring the stability, accuracy and guidance of the aluminum foil feeding during the punching process. The guide groove 9 can feed the aluminum foil in an orderly manner, avoiding confusion and blockage of the aluminum foil and improving production efficiency.

[0042] The use of the opening groove 10 and the guide rail 8 can further improve the alignment accuracy between the positioning block 5 and the punching station 1. This can ensure that the position of the aluminum foil during the punching process is very accurate, thereby improving the quality and performance of the capacitor. Through precise positioning, the adjustment time during the punching process can be reduced, the production speed can be accelerated, and the overall production efficiency can be improved.

[0043] When the positioning block 5 cooperates with the punching table 1 to clamp and position the aluminum foil, the spring 4 is compressed and hidden inside the circular mounting groove 2 .

[0044] By hiding the spring 4 inside the circular mounting groove 2, the positioning block 5 is conveniently moved down to cooperate with the punching table 1 to clamp and position the aluminum foil, so that the aluminum foil can be stably clamped. The elasticity of the spring 4 can provide appropriate pressure to ensure that the clamping force is evenly distributed and prevent the position of the aluminum foil from changing during the punching process. The hidden spring 4 can reduce the mechanical friction and pressure on the aluminum foil, avoid unnecessary damage to the aluminum foil, and maintain the integrity and quality of the aluminum foil.

[0045] The concave groove 7 is provided with a punching position A11 which passes through the positioning block 5 and cooperates with the punching head on the die head, and the punching platform 1 is provided with a punching position B12 which passes through the positioning block 5 and cooperates with the punching head on the die head.

[0046] The design of the punching position A11 and the punching position B12 can ensure that the punching head corresponds to the hole position on the punching station 1 very accurately. This can ensure that the position, shape and size of the holes in the aluminum foil during the punching process meet the design requirements, improve the quality and performance of the capacitor, and due to the matching design between the punching position A11 and the punching position B12, a stable connection is formed between the punching head and the punching station 1. This can ensure that the punching force is evenly distributed on the aluminum foil, avoiding deformation and rupture of the aluminum foil. Similarly, this also helps to improve the overall quality and stability of the capacitor.

[0047] Through accurate punching position and stable punching force, the adjustment time in the punching process can be reduced, thereby increasing production speed and improving overall production efficiency. The combination of punching position A11 and punching position B12 can also reduce the wear of the punching head and extend its service life.

[0048] The aluminum foil pre-punching positioning table for aluminum electrolytic capacitor production can cooperate with the aluminum foil reeling and unwinding mechanism. The aluminum foil is fed in and out along the guide groove 9 surrounded by the guide rails 8 on both sides. The die head of the upper punching die moves downward, pushing the positioning block 5 to move downward, so that the concave groove 7 of the positioning block 5 and the die head of the upper punching die are matched and guided and plugged, ensuring the accurate positioning of the aluminum foil during the punching process. The spring 4 is compressed and hidden to the inner side of the circular installation groove 2, and the aluminum foil is clamped between the positioning block 5 and the punching table 1 to maintain the stability of the aluminum foil during the punching process.

[0049] The aluminum foil is guided and fed in an orderly manner through the guide rail 8 and the guide groove 9 to avoid confusion and blockage of the aluminum foil. The punching die head impacts the aluminum foil through impact force. The position, shape and size of the holes correspond to the punching position A11 and the punching position B12 to ensure the quality and performance of the capacitor. In addition, the waste trough 15 can collect and process the punching waste to prevent the waste from damaging the punching table 1 and the equipment and keep the working area clean.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
