Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic film perforation, specifically a perforation forming machine for aluminum-plastic film of soft-pack batteries. Background Technology

[0002] Aluminum-plastic film is a functional thin film material with a multi-layer composite structure. Its typical structure usually includes a substrate layer, an aluminum foil layer, and a heat-sealing layer. Each layer is composited through a specific process to achieve multiple properties in synergy. In the field of soft-pack battery production, aluminum-plastic film for soft-pack batteries, which is specially adapted to the packaging requirements of soft-pack batteries, undertakes the core function of packaging battery cells. It needs to be closely fitted to the shape of the cell to provide a protective barrier for the cell to isolate it from external moisture, oxygen, and electrolyte corrosion.

[0003] Before wrapping the battery cell, the aluminum-plastic film needs to undergo a perforation forming process. This process uses external force to form a concave cavity structure in the aluminum-plastic film that matches the contour of the battery cell. This process is completed by a soft-pack battery aluminum-plastic film perforation forming machine. In the current industry practice, the operator needs to manually place the cut aluminum-plastic film into the perforation area of ​​the forming machine. To ensure that the aluminum-plastic film is accurately positioned in the perforation forming area on the perforation plate, four sets of marker posts are usually fixed on the surface of the perforation plate as positioning references. When the operator observes that the adjacent two edges of the aluminum-plastic film are in complete contact with the outer walls of the two sets of marker posts, it can be determined that the aluminum-plastic film has been accurately moved to the preset perforation forming area, and then the perforation process is started.

[0004] Although the aluminum-plastic film for soft-pack batteries has a certain degree of stiffness and can maintain its basic shape during manual operation without excessive wrinkling or deformation, in the actual production process, after the aluminum-plastic film is cut by a blade, its cut edges are prone to bending and warping due to the release of cutting stress. This edge shape defect can cause one edge of the aluminum-plastic film to cross the corresponding marker post during placement, making it unable to properly adhere to the outer wall of the marker post, directly destroying the positioning benchmark. Furthermore, the aluminum-plastic film will shift during movement, requiring constant manual adjustment by personnel. This increases the time spent on positioning adjustments before the aluminum-plastic film is punched and formed, prolongs the overall processing cycle, and thus reduces the production efficiency of the aluminum-plastic film. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a punching and forming machine for aluminum-plastic film of soft-pack batteries to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a perforation forming machine for aluminum-plastic film of soft-pack batteries, including a perforation machine. A base plate is fixed to the bottom of the perforation machine. Four sets of limiting posts are installed on the top of the base plate. A second stamping plate is fitted onto the outer wall of each limiting post. A fixing plate is connected to one side of the second stamping plate. Two sets of guide blocks are fixed to the top two sides of the fixing plate. A guide plate is provided on one side of the inner wall of each guide block. Multiple sets of rollers are installed inside the guide plate. Multiple sets of disc springs are installed at the bottom of the second stamping plate. Two sets of through slots are opened inside the second stamping plate. A mold is installed inside each through slot. A first stamping plate is provided on the top of the second stamping plate. A stamping groove is opened at the bottom of the first stamping plate. An aluminum-plastic film is placed on the top of the second stamping plate.

[0007] By adopting the above technical solution, the problem of needing multiple manual adjustments during the process of placing the aluminum-plastic film into the punching area inside the device is solved. Before placing the aluminum-plastic film into the punching area on the top of the second stamping plate, one end of the aluminum-plastic film is inserted into the two sets of guide blocks on the top of the fixed plate. The two sets of guide blocks limit the movement path of the aluminum-plastic film, thereby reducing the frequency of manual adjustment of the movement direction of the aluminum-plastic film. Furthermore, as the aluminum-plastic film passes through the guide blocks, the rollers inside the guide blocks squeeze and flatten the curved edge of the aluminum-plastic film, so that the edge of the aluminum-plastic film will not move past the first or second stop, thereby reducing the need for personnel to adjust the position of the aluminum-plastic film.

[0008] The present invention is further configured such that the inner wall of the guide block is L-shaped, and the distance between the inner walls of the two sets of guide blocks is equal to the width of the aluminum-plastic film.

[0011] Preferably, the port area of ​​the guide block is set to be relatively large, so as to facilitate personnel to insert the aluminum-plastic film into the guide block.

[0012] The present invention is further configured such that one end wall of the guide plate is arc-shaped, and the distance between the bottom wall of the guide plate and the top wall of the fixing plate is greater than the thickness of the aluminum-plastic film.

[0013] Preferably, the guide plate with an arc-shaped end wall can guide the end into which the aluminum-plastic film is inserted to move downwards towards the position below the roller.

[0014] The present invention is further configured such that multiple sets of rollers are installed on one side of the guide plate, and the two ends of the rollers are fixedly installed in the inner wall of the guide plate and the guide block by miniature bearings.

[0015] Preferably, the rollers press and flatten the two sides of the aluminum-plastic film, thereby reducing the curvature of the aluminum-plastic film edges.

[0016] The present invention is further provided that a scratch-resistant plate is installed on the outer wall of one end of the guide block, and the scratch-resistant plate is made of rubber.

[0017] Preferably, during the process of inserting the end of the aluminum-plastic film into the guide block, the operator's hand is very likely to touch the corner of the guide block, and the anti-scratch plate is wrapped around the corner of the guide block to protect the operator's hand.

[0018] The present invention is further configured such that two sets of mounting plates are fixed to the bottom of the fixing plate, the top wall of the fixing plate and the top wall of the second stamping plate are on the same horizontal line, and the height between the bottom wall of the roller and the top wall of the fixing plate is set to 3mm.

[0019] Preferably, the thickness of the aluminum-plastic film is usually around 0.15mm. When the edge of the aluminum-plastic film moves at the bottom of the roller, the roller can squeeze and flatten the curved edge of the aluminum-plastic film.

[0020] The present invention is further configured such that the top of the second stamping plate is provided with two sets of first stop rods and second stop rods, the second stop rods being located at the edge of the top punching area of ​​the second stamping plate, and the bottom of the first stamping plate having multiple sets of through holes and limiting holes.

[0023] Preferably, the guide post limits the lifting direction of the lifting plate and the first stamping plate through the guide sleeve, so that the first stamping plate can be lifted vertically.

[0024] The present invention is further configured such that the inner wall dimension of the stamping groove is larger than the outer wall dimension of the mold, and the top wall surface of the through groove is higher than the top wall surface of the mold.

[0025] Preferably, when the first stamping plate moves upward, the disc spring connected to the bottom of the second stamping plate pushes the second stamping plate upward to return it to its original position, so that the aluminum-plastic film can be separated from the mold.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model solves the problem of multiple manual adjustments required when placing aluminum-plastic film into the punching area inside the device by setting a second stamping plate, a fixed plate, guide blocks, a first stop post, a second stop post, and rollers. Before placing the aluminum-plastic film into the punching area at the top of the second stamping plate, one end of the aluminum-plastic film is inserted into the two sets of guide blocks at the top of the fixed plate. The two sets of guide blocks limit the movement path of the aluminum-plastic film, thereby reducing the frequency of manual adjustment of the movement direction of the aluminum-plastic film. Furthermore, as the aluminum-plastic film passes through the guide blocks, the rollers inside the guide blocks press and flatten the curved edge of the aluminum-plastic film, so that the edge of the aluminum-plastic film will not move beyond the first or second stop post, thereby reducing the need for manual adjustment of the position of the aluminum-plastic film.

[0028] 2. This utility model, by setting a fixing plate and an mounting plate, fixes the fixing plate to one side of the second stamping plate through the mounting plate, and the fixing plate and the top wall of the second stamping plate are on the same horizontal line, so that when the aluminum-plastic film moves on the top of the fixing plate, the aluminum-plastic film can slide along the top of the fixing plate to the top of the second stamping plate. Furthermore, since the first stamping plate and the second stamping plate have the same area, and the fixing plate is set on one side of the second stamping plate, the first stamping plate will not contact the fixing plate and the guide component installed on the top of the fixing plate during the descent process.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The embodiments of this utility model will be described below based on its overall structure.

[0041] First embodiment:

[0042] Please see Figure 1 — Figure 7The system includes a hole flushing machine 1, with a base plate 3 fixed to the bottom of the machine. Four sets of limiting posts 303 are installed on the top of the base plate 3. A second stamping plate 304 is fitted onto the outer wall of each limiting post 303. A fixing plate 4 is connected to one side of the second stamping plate 304. Two sets of guide blocks 402 are fixed to the top two sides of the fixing plate 4. A guide plate 404 is provided on one side of the inner wall of each guide block 402. Multiple sets of rollers 405 are installed inside the guide plate 404. Multiple sets of disc springs 301 are installed at the bottom of the second stamping plate 304. Two sets of through slots 302 are opened inside the second stamping plate 304. A mold 305 is installed inside the through slots 302. A first stamping plate 204 is provided on the top of the second stamping plate 304. A stamping groove 205 is opened at the bottom of the first stamping plate 204. An aluminum-plastic film 5 is placed on top, which solves the problem of multiple manual adjustments required when placing the aluminum-plastic film into the punching area inside the device. Before placing the aluminum-plastic film 5 into the punching area on top of the second punching plate 304, one end of the aluminum-plastic film 5 is inserted into the two sets of guide blocks 402 on the top of the fixed plate 4. The two sets of guide blocks 402 limit the movement path of the aluminum-plastic film 5, thereby reducing the frequency of manual adjustment of the movement direction of the aluminum-plastic film 5. Furthermore, as the aluminum-plastic film 5 passes through the guide blocks 402, the rollers 405 inside the guide blocks 402 squeeze and flatten the curved edge of the aluminum-plastic film 5, so that the edge of the aluminum-plastic film 5 will not move beyond the first stop bar 306 or the second stop bar 307, thereby reducing the need for personnel to adjust the position of the aluminum-plastic film 5.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The inner wall of the guide block 402 is set in an L-shape, and the distance between the inner walls of the two sets of guide blocks 402 is equal to the width of the aluminum-plastic film 5. When the personnel push the aluminum-plastic film 5 inside the two sets of guide blocks 402, the two sets of guide blocks 402 limit the movement direction of the aluminum-plastic film 5.

[0044] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 The height of the inner wall of the port of the guide block 402 is greater than the height of the inner wall of the deep part of the guide block 402, and the port area of ​​the guide block 402 is set to be large, so as to facilitate personnel to insert the aluminum-plastic film 5 into the interior of the guide block 402.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 One end wall of the guide plate 404 is arc-shaped, and the distance between the bottom wall of the guide plate 404 and the top wall of the fixing plate 4 is greater than the thickness of the aluminum-plastic film 5. The guide plate 404 with the arc-shaped end wall can guide the end of the aluminum-plastic film 5 inserted to move downwards towards the position below the roller 405.

[0046] For details regarding the above embodiments, please refer to [link / reference]. Figure 7Multiple sets of rollers 405 are installed on one side of the guide plate 404, and the two ends of the rollers 405 are fixedly installed in the inner wall of the guide plate 404 and the guide block 402 through miniature bearings. The rollers 405 press and flatten the two side edges of the aluminum-plastic film 5, thereby reducing the curvature of the edge bending of the aluminum-plastic film 405.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 7 A scratch-resistant plate 403 is installed on the outer wall of one end of the guide block 402. The scratch-resistant plate 403 is made of rubber. When personnel insert the end of the aluminum-plastic film 5 into the guide block 402, their hands are very likely to touch the corners of the guide block 402. The scratch-resistant plate 403 wraps around the corners of the guide block 402, thereby protecting the personnel's hands.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 6 Two sets of mounting plates 401 are fixed to the bottom of the fixing plate 4. The top wall of the fixing plate 4 is on the same horizontal line as the top wall of the second stamping plate 304. The height between the bottom wall of the roller 405 and the top wall of the fixing plate 4 is set to 3mm. The thickness of the aluminum-plastic film 5 is usually about 0.15mm. When the edge of the aluminum-plastic film 5 moves at the bottom of the roller 405, the roller 405 can squeeze and flatten the curved edge of the aluminum-plastic film 5.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The top of the second stamping plate 304 is provided with two sets of first stop rods 306 and second stop rods 307. The second stop rods 307 are located at the edge of the punching area on the top of the second stamping plate 304. The bottom of the first stamping plate 204 is provided with multiple sets of through holes 206 and limiting holes 207. The first stop rods 306 and second stop rods 307 are both located at the edge of the punching area, serving as the boundary line of the punching area.

[0050] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The top of the first stamping plate 204 is connected to a lifting plate 2, and a booster rod 201 is fixed to the top of the lifting plate 2. Guide sleeves 202 are installed at the four corners of the lifting plate 2. Guide columns 203 are provided inside the guide sleeves 202. The guide columns 203 limit the lifting direction of the lifting plate 2 and the first stamping plate 204 through the guide sleeves 202, so that the first stamping plate 204 can be lifted vertically.

[0051] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3The inner wall dimension of the stamping groove 205 is larger than the outer wall dimension of the mold 305, and the top wall of the through groove 302 is higher than the top wall of the mold 305. When the first stamping plate 204 moves upward, the disc spring 301 connected to the bottom of the second stamping plate 304 pushes the second stamping plate 304 upward to return it to its original position, so that the aluminum-plastic film 5 can be separated from the mold 305.

[0052] Second embodiment:

[0053] Please see Figure 8 The inner sidewalls of the guide block 402 are inclined, the distance between the inner walls at the ports of the two sets of guide blocks 402 is greater than the width of the aluminum-plastic film 5, and the distance between the inner walls of the two sets of guide blocks 402 in the area of ​​the roller 405 is equal to the width of the aluminum-plastic film 5. This allows the inclined inner walls of the guide block 402 to guide the insertion end of the aluminum-plastic film 5 when one end of the aluminum-plastic film 5 is inserted into the guide block 402. This means that the aluminum-plastic film 5 does not need to be carefully manipulated by the personnel when it is inserted into the guide block 402, thereby reducing the time required for the personnel to insert the aluminum-plastic film 5 into the guide block 402.

[0054] In practical operation, before placing the aluminum-plastic film 5 into the punching area on top of the second stamping plate 304, one end of the aluminum-plastic film 5 is first inserted into the guide block 402 from one side of the second stamping plate 304. If the end of the aluminum-plastic film 5 is bent upwards, as the operator manually pushes the aluminum-plastic film 5 into the guide block 402, the arc-shaped guide plate 404 inside the guide block 402 guides the inserted end of the aluminum-plastic film 5 towards the position below the roller 405. The guide blocks 402 on both sides of the top of the fixed plate 4, through multiple sets of rollers 405 installed inside, respectively press and flatten both sides of the aluminum-plastic film 5. When the two sides of the inserted end of the aluminum-plastic film 5 are pressed and flattened, the overall bending arc of the inserted end of the aluminum-plastic film 5 will be reduced. Furthermore, as the aluminum-plastic film 5 moves towards the punching area on top of the second stamping plate 304 through the guide block 402, the rollers 405 press and flatten the two edge parts of the aluminum-plastic film 5, thereby making the aluminum-plastic film 405... 5. The curvature of the edge bending is reduced. When the edge of the aluminum-plastic film 5 contacts the first stop bar 306 and the second stop bar 307, the edge of the aluminum-plastic film 5 after shaping will not bend beyond the first stop bar 306 and the second stop bar 307. If the end of the aluminum-plastic film 5 bends downward, the personnel can manually press the inserted end of the aluminum-plastic film 5 downward when one end of the aluminum-plastic film 5 is inserted into the guide block 402 to reduce the degree of bending of the aluminum-plastic film 5, so that the aluminum-plastic film 5 can move to the bottom position of the roller 405 inside the guide block 402. Thus, the two sets of guide blocks 402 at the top of the fixed plate 4 limit the movement of the aluminum-plastic film 5, thereby reducing the frequency of manual adjustment of the aluminum-plastic film 5 when the personnel manually push the aluminum-plastic film 5 to the top of the second stamping plate 304 punching area. When the edge of the aluminum-plastic film 5 contacts the two sets of first stop bars 306 and second stop bars 307 at the top of the second stamping plate 304, the punching machine 1 can be started to operate.

[0055] When the hole flushing machine 1 is in operation, the booster pump inside the machine pushes the lifting plate 2 downward via the booster rod 201 installed at its end. This causes the lifting plate 2 to slowly move the first pressing plate 204 vertically downward. When the first pressing plate 204 contacts the wall of the second pressing plate 304, the first pressing plate 204 and the second pressing plate 304 compress and fix the aluminum-plastic film 5. As the lifting plate 2 moves downward, the second pressing plate 304 moves downward, and as the second pressing plate 304 moves downward, the film is fixed. The two sets of molds 305 on the top of the base plate 3 are relative to the first stamping plate 204. The molds 305 move into the stamping grooves 205 inside the first stamping plate 204, so that the molds 305 perform a punching and forming process on the aluminum-plastic film 5 that is extruded and fixed between the first stamping plate 204 and the second extrusion plate 304. When the first stamping plate 204 moves upward, the disc spring 301 connected to the bottom of the second stamping plate 304 pushes the second stamping plate 304 upward to return it to its original position, so that the aluminum-plastic film 5 separates from the molds 305.
