Description

Technical Field

[0001] This utility model relates to the field of membrane length adjustment technology, and in particular to a device for adjusting the length of the demetallization layer of a metallized membrane. Background Technology

[0002] Metallized films are composite films in which a very thin metal layer (such as aluminum, nickel, or copper) is deposited on the surface of a polymer matrix (commonly porous polyimide films). The metal layer provides a conductive path, making it widely used in flexible circuits, electronic components, and capacitors. During manufacturing, especially when rolling metallized film capacitors, the metal layer needs to be locally removed at the beginning and end of the film. If the metal layer remains continuous at the cut surface, it can create a short circuit inside the cell or reduce its withstand voltage, leading to problems such as scrapping or capacity reduction in subsequent thermal spraying or charging processes. Therefore, removing these unnecessary metal coatings through processes such as arc welding can significantly improve the reliability and withstand voltage performance of the product.

[0003] In the existing technology, when clamping the two ends of the metallized film, a clamping component with a fixed position is used, which means that the clamping point position at both ends of the metallized film cannot be changed. If metallized films of different lengths need to be processed, the clamping component must be manually disassembled and reassembled. The adjustment process is cumbersome and time-consuming, which not only interrupts the production process, but also easily causes the clamping position deviation due to component disassembly and reassembly, affecting the subsequent metal removal. Therefore, we propose a metallized film metal removal length adjustment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for adjusting the length of the demetallization layer in a metallized film.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metallized film demetallization layer length adjustment device includes an L-shaped frame, a U-shaped frame fixedly embedded in the outer wall of the L-shaped frame, a lead screw rotatably connected inside the U-shaped frame, a servo motor fixedly connected to the outer wall of the U-shaped frame, one end of the output shaft of the servo motor fixedly connected to one end of the lead screw, a rectangular strip threaded onto the outer wall of the lead screw, a mounting plate fixedly connected to the outer wall of the rectangular strip, a guide rod fixedly connected inside the U-shaped frame, a first fixing rubber roller fixedly embedded in the outer wall of the mounting plate, a second fixing rubber roller fixedly embedded in the outer wall of the L-shaped frame, and a metal film clamping assembly provided on the outer wall of the L-shaped frame.

[0007] Preferably, the metal film clamping assembly includes two stepper motors. The L-shaped frame and the outer wall of the mounting plate are both fixedly connected to brackets. The tops of the two brackets are respectively fixedly connected to the outer walls of the two stepper motors. One end of the output shaft of the two stepper motors is respectively fixedly connected to a first sector plate and a second sector plate. A first pressing rubber roller is fixedly embedded in the outer wall of the first sector plate, and a second pressing rubber roller is fixedly embedded in the outer wall of the second sector plate.

[0008] Preferably, the outer wall of the U-shaped frame has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the servo motor output shaft.

[0009] Preferably, a bearing is fixedly sleeved on the other end of the lead screw, and the outer ring of the bearing is fixedly connected to the inner wall of the U-shaped frame. The bearing can reduce the frictional resistance when the lead screw rotates, avoid rotation jamming, and ensure a smooth and stable adjustment process.

[0010] Preferably, the outer wall of the mounting plate has a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the guide rod. The guide rod can provide guidance and restriction for the movement of the mounting plate, and prevent the mounting plate from deflecting when it rotates with the lead screw.

[0011] Preferably, both the L-shaped frame and the mounting plate have through holes on their outer walls, and the inner walls of the two through holes are rotatably connected to the outer walls of the output shafts of the two stepper motors, respectively.

[0012] Preferably, a laser rangefinder is fixedly connected inside the U-shaped frame, and the laser rangefinder can detect the movement distance of the mounting plate in real time.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This solution uses two stepper motors to drive the first and second sector plates to rotate, so that the extrusion pressure of the first and second pressing rubber rollers can quickly fix the two ends of the metallized film. A servo motor drives the lead screw to rotate, so that the rectangular strip drives the mounting plate to move smoothly, thereby adjusting the position of the fixed end of the metallized film and effectively adapting to the processing needs of metallized films of different lengths.

Detailed Implementation

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-3 As shown, a metallization film demetallization layer length adjustment device is disclosed, including an L-shaped frame 1. A U-shaped frame 2 is fixedly embedded in the outer wall of the L-shaped frame 1. A lead screw 3 is rotatably connected inside the U-shaped frame 2. The lead screw 3 can convert the rotational motion of the servo motor 4 into the linear motion of the rectangular bar 5, thereby driving the mounting plate 6 to move.

[0022] The other end of the lead screw 3 is fixedly fitted with a bearing. The outer ring of the bearing is fixedly connected to the inner wall of the U-shaped frame 2. The bearing can reduce the frictional resistance when the lead screw 3 rotates, avoid rotation jamming, and ensure a smooth and stable adjustment process.

[0023] A servo motor 4 is fixedly connected to the outer wall of the U-shaped frame 2. A circular hole is opened on the outer wall of the U-shaped frame 2. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the servo motor 4. One end of the output shaft of the servo motor 4 is fixedly connected to one end of the lead screw 3. A rectangular strip 5 is threaded on the outer wall of the lead screw 3. A mounting plate 6 is fixedly connected to the outer wall of the rectangular strip 5. A guide rod 7 is fixedly connected inside the U-shaped frame 2. A through hole is opened on the outer wall of the mounting plate 6. The inner wall of the through hole is slidably connected to the outer wall of the guide rod 7. The guide rod 7 can provide guidance and restriction for the movement of the mounting plate 6, avoid the mounting plate 6 from deflecting when it rotates with the lead screw 3, and ensure that the mounting plate 6 always moves smoothly along a straight line.

[0024] The outer wall of the mounting plate 6 is fixedly inlaid with a first fixing rubber roller 8. The first fixing rubber roller 8 works in conjunction with the second pressing rubber roller 14. The rubber material has a certain elasticity, which can fix the film material by squeezing force when clamping the metallized film, while avoiding damage to the surface of the metallized film by excessively hard materials.

[0025] The outer wall of the L-shaped frame 1 is fixedly inlaid with a second fixed rubber roller 9. The second fixed rubber roller 9 is compatible with the first pressing rubber roller 13 and is also made of rubber. Together with the first pressing rubber roller 13, it can form a stable clamping force on one end of the metallized film.

[0026] The outer wall of the L-shaped frame 1 is provided with a metal film clamping assembly, which includes two stepper motors 10. The outer walls of the L-shaped frame 1 and the mounting plate 6 are both fixedly connected with brackets. The tops of the two brackets are respectively fixedly connected to the outer walls of the two stepper motors 10. The outer walls of the L-shaped frame 1 and the mounting plate 6 are both provided with through holes. The inner walls of the two through holes are respectively rotatably connected to the outer walls of the output shafts of the two stepper motors 10. One end of the output shafts of the two stepper motors 10 is respectively fixedly connected to a first sector plate 11 and a second sector plate 12. The outer wall of the first sector plate 11 is fixedly inlaid with a first pressing rubber roller 13, and the outer wall of the second sector plate 12 is fixedly inlaid with a second pressing rubber roller 14.

[0027] A laser rangefinder 15 (LDM301) is fixedly connected inside the U-shaped frame 2. The laser rangefinder 15 can detect the moving distance of the mounting plate 6 in real time. After the laser beam emitted by the laser rangefinder 15 shines on the transmitter plate installed on the surface of the mounting plate 6, it will be reflected. The reflected laser signal is captured by the photosensitive receiver element built into the laser rangefinder 15, and the distance is detected by the round-trip time difference.

[0028] Working principle: One end of the metallized film is placed between the first fixed rubber roller 8 and the first pressing rubber roller 13, and the other end is placed between the second fixed rubber roller 9 and the second pressing rubber roller 14. As the two stepper motors 10 operate, they drive the first sector plate 11 and the second sector plate 12 to rotate, respectively, causing the first sector plate 11 and the second sector plate 12 to rotate in opposite directions. The rotational motion is converted into an arc-shaped pressing trajectory. The first pressing rubber roller 13 and the second pressing rubber roller 14 fix both ends of the metallized film with extrusion force. As the servo motor 4 operates, it drives the lead screw 3 to rotate. The rotation of the lead screw 3 causes the rectangular bar 5 to move to the right. The rightward movement of the rectangular bar 5 causes the mounting plate 6 to move to the right. The rightward movement of the mounting plate 6 causes the fixed end of the metallized film to move to the right. According to the length of the metallized film, it moves to a corresponding distance. This distance is detected by the laser rangefinder 15. When the mounting plate 6 moves, the guide rod 7 slides along the through hole, which guides the mounting plate 6.

[0029] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the servo motor 4, the stepper motor 10, and the laser rangefinder 15 to facilitate the control of the overall operation.
