Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, and in particular to a winding device for capacitor processing. Background Technology

[0002] For example, Chinese Patent No. CN216597308U discloses a winding film capacitor manufacturing device, in which one end of the film layer wound inside the unwinding roller is wound around the outside of the inner support of the capacitor, and then the lower support plate is rotated and adjusted by the first motor, so that the film layer can be wound uniformly around the outside of the inner support of the capacitor.

[0003] However, the aforementioned winding device requires operators to manually press the first end of the film layer onto the surface of the inner support of the capacitor during the initial winding stage. This process necessitates repeated adjustments to the film tension and bonding angle. This is time-consuming and labor-intensive, reducing production efficiency. Furthermore, it is difficult to precisely control the bonding pressure and position, easily leading to air bubbles or wrinkles between the film layer and the inner support, which can become potential sources of partial discharge during capacitor operation. Secondly, the winding process lacks a dynamic pressing mechanism. Under high-speed winding conditions, fluctuations in film layer tension can cause problems such as interlayer loosening and slippage in the wound portion, especially when the film material has uneven thickness or differences in tensile properties. This loosening phenomenon is more pronounced. This defect directly affects the volume density and electrical insulation performance of the capacitor, increasing the difficulty of quality control in subsequent packaging processes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a winding device for capacitor processing, which solves the technical problems of existing technologies that rely on manual operation to press and adhere the initial film to the capacitor surface, making it difficult to accurately control the bonding pressure and position, and lacking a dynamic pressing mechanism during the winding process.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a winding device for capacitor processing, including a processing table, support frames symmetrically installed on both sides of the processing table, a capacitor body placed between the two support frames, a winding mechanism for driving the capacitor body to rotate on the support frames, a traction roller for guiding the film roll on the processing table, a bonding mechanism for pressing the film roll to adhere to the capacitor body on the processing table, and a dynamic pressing mechanism for ensuring that the film roll always adheres to the capacitor body on the support frames.

[0006] The bonding mechanism includes an electric guide rail installed in a groove on the processing table, an electric slider slidably connected to the inner wall of the groove on the electric guide rail, an electric push rod installed at the bottom of the electric slider, an installation plate installed at the free end of the electric push rod, an adsorption plate installed at the bottom of the installation plate through a connecting column, an adsorption hole arrayed at the bottom of the adsorption plate, and a vacuum tube installed on the adsorption plate.

[0007] A further improvement is that an electric lifting rod is mounted on the mounting plate, and the free end of the electric lifting rod passes through the mounting plate and is equipped with a cutting blade.

[0008] A further improvement is that the dynamic pressing mechanism includes an arc-shaped mounting base mounted on the processing table via a support rod, and the arc-shaped mounting base is located outside the capacitor body. A sliding sleeve is mounted on the arc-shaped mounting base, an electromagnetic block is mounted inside the sliding sleeve, an elastic rope is mounted on the electromagnetic block, and a permanent magnet rod sliding inside the sliding sleeve is mounted at the end of the elastic rope. A portal frame is fixedly connected to the outer end of the permanent magnet rod, and a pressing roller shaft is rotatably connected inside the portal frame.

[0009] A further improvement is that the winding mechanism includes a bidirectional electric telescopic rod installed on the processing table, and the free ends of the bidirectional electric telescopic rod are respectively connected to two support frames. A rotating shaft is rotatably connected to the support frame, and a clamping plate is installed at the end of each rotating shaft. A winding motor that drives the rotating shaft to rotate is installed on the support frame, and an automatic clamping and feeding component is provided on the processing table.

[0010] A further improvement is that T-shaped guide grooves are symmetrically provided on both sides of the processing table, and T-shaped sliders that are adapted to them slide in the T-shaped guide grooves, with the top of the T-shaped sliders connected to the support frame.

[0011] A further improvement is that the feeding assembly includes a feeding platform installed on the processing table, an electric telescopic rod installed on the processing table, and an electric slider that slides on an electric guide rail installed on the top of the electric telescopic rod. A pneumatic gripper is installed on the free end of the electric telescopic rod.

[0012] By means of the above technical solution, this utility model provides a winding device for capacitor processing, which has at least the following beneficial effects: 1. This utility model uses an electric slider to move to the right along an electric guide rail until the adsorption plate is above the film roll. Then, the electric push rod is activated to move the adsorption plate down to contact the film roll. A negative pressure is generated through a vacuum tube to adsorb the film roll onto the adsorption plate. Then, the electric slider is driven to reset the adsorption plate and push it down again to fit against the surface of the capacitor body. No manual pressing is required for bonding, which improves bonding efficiency and accuracy.

[0013] 2. This utility model generates a repulsive force between the electromagnetic block and the permanent magnet rod by energizing the electromagnetic block, which pushes the permanent magnet rod to slide outward along the inner wall of the sliding sleeve. This, in turn, pushes the pressing roller shaft on the gantry frame to adhere to the surface of the capacitor body. Thus, during the winding process, the rotating pressing roller shaft dynamically presses the film roll onto the capacitor body, avoiding the problems of interlayer loosening and slippage during winding.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Currently available technologies rely on manual pressing and bonding of the initial film to the capacitor surface, which suffers from difficulties in precisely controlling the bonding pressure and position, and lacks a dynamic pressing mechanism during winding. This embodiment provides a capacitor winding device that automatically presses the film roll onto the capacitor surface without manual operation, improving processing efficiency and winding accuracy. Furthermore, it dynamically presses the film roll during winding, ensuring a tight fit to the capacitor surface and preventing loosening. Please refer to... Figures 1-6 The capacitor winding equipment includes a processing table 1, with support frames 2 symmetrically mounted on both sides of the processing table 1. A capacitor body 3 is placed between the two support frames 2. A winding mechanism 4 is provided on the support frames 2 to drive the capacitor body 3 to rotate. A traction roller 5 is provided on the processing table 1 to guide the film roll. A bonding mechanism 6 is provided on the processing table 1 to press the film roll onto the capacitor body 3. A dynamic pressing mechanism 7 is provided on the support frames 2 to keep the film roll always in contact with the capacitor body 3. The capacitor body 3 is clamped and placed between the two support frames 2 by the feeding assembly 45. Then, the winding mechanism 4 clamps and fixes the capacitor body 3 and drives it to rotate. Before this, the bonding mechanism 6 adsorbs and presses the film roll pulled by the traction roller 5 onto the surface of the capacitor body 3. Since the film roll has a certain degree of stickiness, when the capacitor body 3 rotates, it drives the film roll to rotate synchronously and wrap around its surface. With the help of the dynamic pressing mechanism 7, the film roll is always pressed onto the capacitor body 3 during the winding process, thereby preventing the winding from becoming loose.

[0019] Because existing technologies involve manually pressing and bonding the initial film to the capacitor surface, it is difficult to precisely control the bonding pressure and position. Therefore, this device is equipped with a bonding mechanism 6. The bonding mechanism 6 includes an electric guide rail 61 installed in a groove on the processing table 1. An electric slider 62 is slidably connected to the inner wall of the groove on the electric guide rail 61. An electric push rod 63 is installed at the bottom of the electric slider 62. A mounting plate 64 is installed at the free end of the electric push rod 63. An adsorption plate 65 is installed at the bottom of the mounting plate 64 through a connecting post. Adsorption holes 66 are arrayed at the bottom of the adsorption plate 65. A vacuum tube 67 is installed on the top. The electric slider 62 is driven to move to the right along the electric guide rail 61 until the adsorption plate 65 is above the traction film roll. Then, the electric push rod 63 is activated to move the adsorption plate 65 down to contact the film roll. The vacuum tube 67 generates negative pressure, and the film roll is adsorbed onto the adsorption plate 65 through the adsorption hole 66 at the bottom of the adsorption plate 65. Then, the electric slider 62 is driven to move the adsorption plate 65 back to its original position. The adsorption plate 65 is then pushed down again to fit against the surface of the capacitor body 3. No manual pressing is required for bonding, which improves bonding efficiency and bonding accuracy.

[0020] Furthermore, an electric lifting rod 68 is installed on the mounting plate 64. The free end of the electric lifting rod 68 passes through the mounting plate 64 and is equipped with a cutting blade 69. After the winding is completed, the electric lifting rod 68 is activated to push the cutting blade 69 down to cut the film roll.

[0021] To improve the feeding and winding efficiency, the device is also equipped with a winding mechanism 4. The winding mechanism 4 includes a bidirectional electric telescopic rod 41 installed on the processing table 1, and the free ends of the bidirectional electric telescopic rod 41 are respectively connected to two support frames 2. A rotating shaft 42 is rotatably connected to the support frame 2, and a clamping plate 43 is installed at the end of each rotating shaft 42. A winding motor 44 that drives the rotating shaft 42 to rotate is installed on the support frame 2. An automatic clamping and feeding assembly 45 is provided on the processing table 1. The capacitor body 3 is clamped and placed between the two support frames 2 by the feeding assembly 45. Then, the bidirectional electric telescopic rod 41 is started to pull the two support frames 2 to move relative to each other until the two clamping plates 43 clamp and fix the capacitor body 3 from both sides. Then, the winding motor 44 is started to drive the capacitor body 3 to rotate for winding. After winding is completed, the capacitor body 3 is released and rolls down the ramps set on the two support frames 2. The whole process is automated, which improves the winding efficiency.

[0022] To improve the stability of the sliding of the support frame 2, T-shaped guide grooves are symmetrically opened on both sides of the processing table 1 in the device. T-shaped sliders 46 that are adapted to the T-shaped guide grooves slide in the T-shaped guide grooves, and the top of the T-shaped sliders 46 are connected to the support frame 2. As the two support frames 2 are pulled and slid, the T-shaped sliders 46 at their bottoms move relative to each other along the T-shaped sliding grooves opened on the processing table 1, thereby improving the stability of the sliding of the support frame 2.

[0023] The loading assembly 45 includes a loading platform 451 mounted on the processing table 1. An electric telescopic rod 452 is mounted on the processing table 1, and an electric slider 62 that slides on the electric guide rail 61 is also mounted on the top of the electric telescopic rod 452. A pneumatic gripper 453 is mounted on the free end of the electric telescopic rod 452. When the electric telescopic rod 452 is activated, the pneumatic gripper 453 at its bottom moves down to above the capacitor body 3 placed on the loading platform 451. Then, the pneumatic gripper 453 picks up the capacitor body 3 and activates the electric slider 62 on the electric telescopic rod 452 to slide it between the two support frames 2 for clamping and fixing. At the same time as the electric telescopic rod 452 moves, the fitting mechanism 6 moves synchronously to make room for the electric telescopic rod 452.

[0024] Example 2 Based on Example 1, such as Figures 1-6As shown, under high-speed winding conditions, tension fluctuations in the thin film layer can cause problems such as interlayer loosening and slippage in the wound portion. Therefore, the device is also equipped with a dynamic pressing mechanism 7. The dynamic pressing mechanism 7 includes an arc-shaped mounting base 71 mounted on the processing table 1 via a support rod. The arc-shaped mounting base 71 is located outside the capacitor body 3. A sliding sleeve 72 is mounted on the arc-shaped mounting base 71. An electromagnetic block 73 is mounted inside the sliding sleeve 72. An elastic rope 74 is mounted on the electromagnetic block 73. The end of the elastic rope 74 is fitted with a sliding part that slides inside the sliding sleeve 72. A permanent magnet rod 75 is fixed to the outer end of a portal frame 76. A pressing roller shaft 77 is rotatably connected inside the portal frame 76. During the winding process, the electromagnetic block 73 is energized, thereby generating a repulsive force between it and the permanent magnet rod 75. This pushes the permanent magnet rod 75 to slide outward along the inner wall of the sliding sleeve 72, which in turn pushes the pressing roller shaft 77 on the portal frame 76 to adhere to the surface of the capacitor body 3. Thus, during the winding process, the rotating pressing roller shaft 77 dynamically presses the film roll onto the capacitor body 3, avoiding the problems of interlayer loosening and slippage during winding.
