Description

Technical Field

[0001] This application relates to the field of lead processing technology for capacitor elements, and in particular to a lead processing apparatus for capacitor elements. Background Technology

[0002] Leads are conductors that connect capacitor plates to external circuits. In electrical terminology, the wires extending from the plates are called "electrodes" because they are the channels for charge transfer. In practical structures, leads are typically fixed to printed circuit boards (PCBs) by soldering or through-hole mounting to achieve electrical connections.

[0003] Aluminum foil is commonly used as a lead material in the industry. Aluminum foil is in strip form and needs to be folded to a specified thickness during processing. Then, the aluminum foil is cut to a specified length to complete the aluminum foil processing.

[0004] During the processing, the aluminum foil needs to go through processes such as folding, pressing and cutting. In order to improve the service life and electrochemical stability of the capacitor element, the lead end needs to be cut into an arc shape. Therefore, aluminum foil is often stamped and cut with an arc-shaped block.

[0005] During prolonged operation, due to the thinness and light weight of the aluminum foil, the front section of the aluminum foil is cut, and the rear section of the aluminum foil may stick to the cut pieces, causing obstruction when the subsequent aluminum foil is conveyed forward. This can easily lead to material jamming during the pressing process. As a result, the workers need to remove some of the jammed aluminum foil, readjust the process, and then continue the operation. This not only prolongs the processing time but also increases the amount of aluminum foil waste and reduces the processing efficiency of the lead wire processing equipment. Summary of the Invention

Simultaneously, the cooperating components drive the aluminum foil to move. During this process, the folding component folds both sides of the aluminum foil, and the pressing component compacts the foil. The foil then enters the feeding channel and passes through the gap between the limiting plate and the feeding channel. The shearing cylinder is activated, causing the shearing block to move. The shearing block, in conjunction with the shearing channel, shears the aluminum foil. Simultaneously, an external air source blows out the sheared aluminum foil through an air pipe, guiding it through a guide tube into the receiving box, thus completing the aluminum foil processing. By setting the limiting plate, the shearing block cuts the aluminum foil. If adhesion occurs, the rear end of the aluminum foil is detached from the shearing block due to the limiting plate, while the front end is blown by the air source and falls into the receiving box through the guide tube. This ensures that no aluminum foil remains in the feeding channel, allowing the rear end of the aluminum foil to move smoothly. This reduces the possibility of aluminum foil being unable to be conveyed due to adhesion to the shearing block, reduces the risk of foil jamming and waste, and improves the processing efficiency of the lead wire processing equipment.

[0027] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0028] This application discloses a lead processing apparatus for capacitor elements. (Refer to...) Figure 1 The lead processing equipment for capacitor elements includes a machine body 1. One end of the machine body 1 is provided with an unwinding roller 11 and a rotating component 12 for driving the unwinding roller 11 to rotate. The machine body 1 is provided with a folding component 2 for folding aluminum foil, a pressing component 3 for pressing aluminum foil, and a cutting component 4 for cutting aluminum foil.

[0029] The rotating component 12 drives the unwinding roller 11 to unwind the aluminum foil, which moves in conjunction with the pressing component 3. Then, the folding component 2 folds the aluminum foil on both sides during the movement and brings it closer to the center. Subsequently, the pressing component 3 presses the folded part onto the surface of the aluminum foil to form an aluminum foil of a specified width. Finally, the cutting component 4 cuts the aluminum foil to a specified length, thus realizing the processing of the aluminum foil.

[0030] Reference Figure 1 The unwinding roller 11 has a built-in clamping bar, which moves by means of a hydraulic component inside the unwinding roller 11 to press against the aluminum foil strip, thereby achieving the installation of the aluminum foil. The rotating component 12 is a motor, which is mounted on the machine body 1 and coaxially connected to the unwinding roller 11. When the rotating frame is started, it drives the unwinding roller 11 to rotate, continuously feeding aluminum foil for subsequent processes.

[0031] Reference Figure 2 The folding assembly 2 includes a pressure roller 21, a clamping roller 22, a guide plate 23, and a pressure plate 24. An adjustment assembly 5 is provided on the machine body 1, which includes an adjustment screw 51, a moving seat 52, a lifting column 53, a locking bolt 54, and an adjustment bolt 55. The adjustment screw 51 is rotatably connected to the machine body 1 and is perpendicular to the aluminum foil conveying direction. The moving seat 52 is slidably fitted onto the machine body 1 and threadedly engaged with the adjustment screw 51. The lifting column 53 is vertically slidably fitted onto the moving seat 52, and the locking bolt 54 is threadedly engaged with the moving seat 52 and abuts against the surface of the lifting column 53. The adjustment bolt 55 is vertically rotatably connected to the moving seat 52 and threadedly engaged with the top of the lifting column 53. A connecting frame 74 is bolted to the bottom end of the lifting column 53, and the pressure roller 21 is rotatably connected to the connecting frame 74. The aluminum foil moves between the pressure roller 21 and the surface of the machine body 1.

[0032] When adjusting the position of the pressure roller 21, rotate the adjusting screw 51 to move the moving seat 52 to the designated position, then rotate the adjusting bolt 55 to lower the lifting column 53, which in turn lowers the pressure roller 21 to the designated height. Finally, rotate the locking bolt 54 to lock the lifting column 53, thus completing the installation of the pressure roller 21.

[0033] Reference Figure 2 and Figure 3 The mounting assembly 6 includes support columns 61, connecting slide rails 62, mounting blocks 63, and securing bolts 64. Two support columns 61 are vertically fixed to the body 1. The connecting slide rails 62 are bolted between the two support columns 61 and have several threaded holes. The mounting blocks 63 slide on the connecting slide rails 62. The securing bolts 64 are threaded into the threaded holes and abut against the mounting blocks 63.

[0034] Reference Figure 3 and Figure 4 The mounting block 63 is equipped with a clamping assembly 7, which includes a connecting block 71, a clamping block 72, a top plate 73, a connecting frame 74, a moving block 75, and a clamping screw 76. The connecting block 71 is bolted to the mounting block 63. A clamping groove is formed between the mounting block 63 and the connecting block 71, and a clamping cavity is formed between them. The connecting frame 74 is a portal frame that slides vertically within the clamping cavity. The top plate 73 is fixedly connected to the end of the connecting frame 74, and two top plates 73 are provided.

[0035] Reference Figure 3 and Figure 4The clamping block 72 is a trapezoidal block, and two clamping blocks are provided. Each clamping block 72 has a waist-shaped groove, through which it is fitted onto the connecting frame 74. The clamping blocks 72 are located above the top plate 73, with the two clamping blocks 72 facing each other. The clamping groove is located between the two clamping blocks 72. The bottom walls of the mounting block 63 and the connecting block 71 are both in contact with the top wall of the clamping block 72. The clamping screw 76 is rotatably connected to the connecting block 71. The moving block 75 is slidably fitted in the clamping cavity and threadedly engaged with the clamping screw 76. The moving block 75 has a clamping inclined surface that is in contact with the connecting frame 74. The guide plate 23 is vertically positioned within the clamping groove, parallel to the aluminum foil conveying direction, and located between the clamping wheel 22 and the pressing assembly 3. The two clamping blocks 72 clamp the guide plate 23.

[0036] Reference Figure 2 Two fixing plates 221 are bolted to the machine body 1 and are arranged opposite each other. A clamping wheel 22 is vertically rotatably connected to the end of the fixing plate 221 and is located between the guide plate 23 and the pressure wheel 21. A pressure plate 24 is bolted to the machine body 1 and is located between the guide plate 23 and the pressing assembly 3, with a gap between the pressure plate 24 and the machine body 1.

[0037] During folding, the moving aluminum foil is squeezed by the pressure roller 21, causing the two sides of the aluminum foil to be initially folded and lifted. Then, it is folded into a vertical state by the influence of the two clamping rollers 22. Subsequently, it is guided and restricted by the guide plate 23. Finally, the aluminum foil passes through the gap between the pressure plate 24 and the machine body 1. The two sides of the aluminum foil overlap with the aluminum foil surface by the influence of the pressure plate 24, thus achieving the folding effect on both sides of the aluminum foil.

[0038] Reference Figure 1 and Figure 5 The pressing assembly 3 includes a pressing frame 31, a rotating roller 32, a pressure roller 33, and a rotating motor 34. The pressing frame 31 is U-shaped and fixedly connected to the machine body 1, with lifting grooves at both ends. The rotating roller 32 is rotatably connected to the pressing frame 31, and the rotating motor 34 is mounted on the pressing frame 31 and coaxially connected to the rotating roller 32. The pressure roller 33 is a rubber roller, with lifting blocks 331 rotatably connected to both ends, and the lifting blocks 331 slidingly engaging within the lifting grooves. Both ends of the pressing frame 31 are threaded with pressure bolts 311, and pressure springs 312 are installed between the pressure bolts 311 and the lifting blocks 331.

[0039] Reference Figure 5 and Figure 6The pressure frame 31 is equipped with a lifting assembly 35, which includes a rotating rod 351, a support plate 352, and a control lever 353. The rotating rod 351 is rotatably connected between two lifting blocks 331, and the control lever 353 is fixedly connected to one end of the rotating rod 351. Two support plates 352 are provided and are bolted to the side wall of the pressure frame 31. The rotating rod 351 has a notch 3511. During operation, part of the support plate 352 is located inside the notch 3511; when removing the stuck aluminum foil, the support plate 352 is located outside the notch 3511.

[0040] When pressing aluminum foil, the rotating motor 34 is started, causing the rotating roller 32 to rotate. Through friction, the pressure roller 33 rotates to press the aluminum foil and move it. If aluminum foil gets stuck, the operator rotates the control lever 353, causing the rotating rod 351 to rotate. The notch 3511 rotates and faces upward, causing the rotating rod 351 to rise due to contact with the support plate 352. The lifting block 331 rises, driving the pressure roller 33 to rise, increasing the distance between the pressure roller 33 and the rotating roller 32, thus facilitating the removal of the stuck aluminum foil.

[0041] Reference Figure 1 , Figure 7 and Figure 8 The cutting component 4 includes a fixed base 41, a shearing cylinder 42, and a shearing block 43. A vibration component 44 is provided on the machine body 1, which includes a drive cylinder 441, a sliding rail 442, a connecting spring 443, and rubber blocks 444. The sliding rail 442 is fixedly connected to the machine body 1, and the fixed base 41 is slidably fitted onto the sliding rail 442. The drive cylinder 441 is mounted on the machine body 1, and a retaining ring 4411 is fixedly connected to the output shaft of the drive cylinder 441. A connecting sleeve 411 is fixedly connected to the fixed base 41, and the output shaft of the drive cylinder 441 passes through the connecting sleeve 411. The connecting spring 443 is disposed between the connecting sleeve 411 and the retaining ring 4411. Two rubber blocks 444 are provided, one fixedly connected to the output shaft of the drive cylinder 441, and the other fixedly connected to the machine body 1. The fixed base 41 is located between the two rubber blocks 444.

[0042] Reference Figure 7 and Figure 9 The fixed base 41 has a feeding channel 412 and a shearing channel. The feeding channel 412 is horizontally positioned and aligned with the discharge card of the pressing assembly 3. The shearing channel is vertically positioned and is connected to the feeding channel 412. The shearing cylinder 42 is vertically mounted on the top of the fixed base 41. The shearing block 43 is fixedly connected to the output shaft of the shearing cylinder 42 and slides within the shearing channel.

[0043] Reference Figure 9 and Figure 10A feeding assembly 8 is provided on the fixed base 41. The feeding assembly 8 includes a limiting plate 81, an air blowing pipe 82, and a guide pipe 83. The limiting plate 81 is L-shaped and is bolted to the fixed base 41. A gap is left between the limiting plate 81 and the bottom wall of the feeding channel 412, through which the pressed aluminum foil passes. One end of the guide pipe 83 is fixedly connected to the fixed base 41. The air blowing pipe 82 is located on the fixed base 41, with its air outlet facing the guide pipe 83. The air blowing pipe 82 is connected to an external air source. A receiving box 13 is placed on the machine body 1, and the other end of the guide pipe 83 is located directly above the receiving box 13.

[0044] Reference Figure 1 and Figure 10 The bottom of the fixed base 41 is fixedly connected to the discharge pipe 413, which is aligned with the shearing channel. The machine body 1 is also equipped with a waste box 14, and the outlet end of the discharge pipe 413 faces the waste box 14.

[0045] During shearing, the pressed aluminum foil passes through the gap between the pressure plate 24 and the feeding channel 412. The shearing cylinder 42 is activated, and the shearing block 43 descends to press and shear the end of the aluminum foil. The waste material passes through the shearing channel and the discharge pipe 413 and falls into the waste box 14. The aluminum foil that has been sheared at the front is affected by the gas sprayed from the air pipe 82 and enters the guide pipe 83, finally falling into the receiving box 13. During this process, each time the aluminum foil is sheared, the drive cylinder 441 is activated, causing one of the rubber blocks 444 to strike the fixed seat 41. The fixed seat 41 moves and stops moving when it contacts another rubber block 444. The waste material adhering to the shearing block 43 is shaken off. During reset, the fixed seat 41 is moved by the connecting spring 443. The shaking component 44 is used to assist in shaking off the aluminum foil adhering to the shearing block 43.

[0046] The implementation principle of the lead wire processing equipment for capacitor elements in this application embodiment is as follows: During processing, the rotating component 12 drives the unwinding roller 11 to rotate to unwind aluminum foil. The aluminum foil is affected by the pressure roller 21, causing the two sides to be initially folded. Then, it is further folded into a vertical state by the pressing roller 22. Subsequently, it is restricted by the guide plate 23 and finally passes through the gap between the pressure plate 24 and the machine body 1, so that the two sides of the aluminum foil are in contact with the surface. During this process, the rotating motor 34 is started, the rotating roller 32 rotates and drives the pressure roller 33 to rotate. The aluminum foil is pressed by the pressure between the rotating roller 32 and the pressure roller 33 and moves into the feeding channel 412. The aluminum foil passes through the gap between the limiting plate 81 and the bottom wall of the feeding channel 412. The shearing cylinder 42 is started, the shearing block 43 moves and shears the aluminum foil. The waste falls into the waste box 14. The air blowing pipe 82 blows air and blows the front section of the aluminum foil into the guide pipe 83, and finally falls into the receiving box 13, realizing the automatic processing of aluminum foil.

[0047] By setting a limiting plate 81, the shearing block 43 cuts the aluminum foil. If adhesion occurs, the end of the aluminum foil in the rear section will be detached from the shearing block 43 due to the influence of the limiting plate 81. The aluminum foil in the front section will be blown by the air source and fall into the receiving box 13 through the guide tube 83. This ensures that there is no aluminum foil stuck in the feeding channel 412 and that the aluminum foil in the rear section can move smoothly. It reduces the possibility that the aluminum foil cannot be conveyed due to adhesion to the shearing block 43, reduces the risk of aluminum foil jamming and waste, and improves the processing efficiency of the lead wire processing equipment.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
