Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery cell production equipment, and in particular to a device for removing the insulating protective film from lithium battery cells. Background Technology

[0002] In the production process of lithium-ion battery cells, to ensure their safety, an insulating protective film is usually wrapped around the surface of the cell to prevent short circuits caused by direct contact between the cell and the aluminum casing. The surface of a lithium-ion battery cell generally has six sides, with different materials and coverage of the insulating protective film on each side. For example, the top and bottom sides, left and right sides, and front and back sides of the cell are opposite each other. The top side has raised electrodes. The top, bottom, and back sides are usually completely covered by an insulating protective film made of PET or acrylic material, while the left and right sides are partially covered by an insulating protective film made of structural adhesive. The front side is also partially covered by an insulating protective film. Due to the strong adhesion of the insulating protective film, it is very difficult to remove it completely and quickly. Currently, direct contact removal methods such as manual or mechanical scraping are not only inefficient but also result in a lot of residue on the cell surface, which can easily damage the aluminum material on the cell surface, affecting the quality and performance of the cell and making it difficult to meet the needs of large-scale, high-efficiency production. Therefore, developing an efficient and reliable device for removing the insulating protective film from lithium-ion battery cells is of significant practical importance.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when it is necessary to change the flow rate of the film-removing agent, it cannot be adjusted; if the film-removing agent dosage is too large, it will waste the film-removing agent and cause unnecessary losses; if the film-removing agent dosage is too small, the film-removing gun will not be able to completely remove the protective film on the surface of the battery cell, which will be detrimental to subsequent processing. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that when it is necessary to change the flow rate of the film removal agent, it cannot be adjusted. If the film removal agent dosage is too large, it will waste the film removal agent and cause unnecessary losses. If the film removal agent dosage is too small, the film removal gun will not be able to completely remove the protective film on the surface of the battery cell, which will be detrimental to subsequent processing. To this end, we propose a film removal device for the insulating protective film of lithium battery cells.

[0005] To achieve the above objectives, this application adopts the following technical solution: a film removal device for insulating protective film of lithium battery cells, comprising a processing table, a lithium battery cell body slidably connected to one side of the processing table, a film removal gun installed on one side of the processing table, an adjustment device provided at one end of the film removal gun, the adjustment device comprising a fixing tube, the fixing tube being fixedly connected to one end of the film removal gun, four fixing blocks being fixedly connected to one end of the film removal gun, a round rod being fixedly connected to the side of two of the fixing blocks that are close to each other, a rotating block being rotatably connected to the arc surface of the round rod, a conical sleeve being fixedly connected to one side of the rotating block, two setting blocks being fixedly connected to the surface of the conical sleeve, and a setting rod being fixedly connected to the side of the two setting blocks that are close to each other.

[0006] Preferably, the arc surface of the setting rod is rotatably connected to a square frame, and the arc surface of the film removal gun is fixedly connected to two U-shaped frames, with a plug inserted slidably on the inner surface of the U-shaped frame.

[0007] Preferably, the arc surface of the insertion rod is fitted with a first spring, and the two ends of the first spring are fixedly connected to the surface of the spiral frame and one end of the insertion rod, respectively.

[0008] Preferably, the arc surface of the round rod is fitted with two torsion springs, and the two ends of the torsion springs are respectively fixedly connected to one side of the fixed block and one side of the rotating block.

[0009] Preferably, the surface of the processing table is provided with a clamping device, which includes three fixed frames. All three fixed frames are fixedly connected to the surface of the processing table. A rotating rod is rotatably connected to the inner surface of the three fixed frames. A gear is fixedly connected to the arc surface of the rotating rod. A toothed plate meshes with the surface of the gear. A moving block is fixedly connected to one side of the toothed plate. A side plate is fixedly connected to the surface of the processing table.

[0010] Preferably, a first anti-slip plate is fixedly connected to one side of the side plate, and a second anti-slip plate is fixedly connected to one side of the movable block.

[0011] Preferably, two guide frames are fixedly connected to the surface of the processing table, and guide rods are slidably connected to the inner surface of the guide frames, with one end of the guide rods fixedly connected to the moving block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting an adjustment device, the flow rate of the film-removing agent can be adjusted, avoiding the problem that the operator needs to change the flow rate of the film-removing agent but cannot adjust it. Excessive film-removing agent dosage will waste film-removing agent and cause unnecessary losses, while insufficient film-removing agent dosage will prevent the film-removing gun from completely removing the protective film on the surface of the battery cell, which will be detrimental to subsequent processing. The design of the adjustment mechanism enhances the flexibility of the device, saves film-removing agent, and improves the efficiency of the device.

[0014] In this invention, a clamping device is provided to achieve the effect of clamping the lithium battery cell body, avoiding the problem of shaking when removing the film from the lithium battery cell body. Usually, the clamping device for the lithium battery cell body is relatively complex and not conducive to the operation of the operator. The improved clamping structure can flexibly clamp the lithium battery cell body, making it convenient to place or remove the lithium battery cell body from the surface of the processing table.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: a film removal device for the insulating protective film of lithium battery cells, including a processing table 1, a lithium battery cell body 2 slidably connected to one side of the processing table 1, a film removal gun 3 installed on one side of the processing table 1, and an adjustment device 4 at one end of the film removal gun 3. By setting the adjustment device 4, the flow rate of the film removal agent can be adjusted, avoiding the problem that the operator needs to change the flow rate of the film removal agent but cannot adjust it. If the film removal agent dosage is too large, it will waste the film removal agent and cause unnecessary losses. If the film removal agent dosage is too small, the film removal gun 3 will not be able to completely remove the protective film on the surface of the battery cell, which will be detrimental to subsequent processing. The design of the adjustment mechanism enhances the flexibility of the device, saves the film removal agent, and improves the efficiency of the device. The surface of the processing table 1 is equipped with a clamping device 5. By setting the clamping device 5, the lithium battery cell body 2 is clamped, avoiding the problem of shaking when removing the film from the lithium battery cell body 2. Usually, the clamping device for the lithium battery cell body 2 is relatively complex and not conducive to the operation of the operator. The improved clamping structure can flexibly clamp the lithium battery cell body 2, making it convenient to place or remove the lithium battery cell body 2 from the surface of the processing table 1.

[0024] The specific settings and functions of the adjustment device 4 and the clamping device 5 will be explained in detail below.

[0025] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting device 4 includes a fixed tube 401, which is fixedly connected to one end of the film removal gun 3. Four fixed blocks 403 are fixedly connected to one end of the film removal gun 3. A round rod 404 is fixedly connected to the side of two fixed blocks 403 that are close to each other. A rotating block 405 is rotatably connected to the arc surface of the round rod 404. A conical sleeve 402 is fixedly connected to one side of the rotating block 405. Two setting blocks 406 are fixedly connected to the surface of the conical sleeve 402. A setting rod 407 is fixedly connected to the side of two setting blocks 406 that are close to each other. A square frame 408 is rotatably connected to the arc surface of the setting rod 407. Two U-shaped frames 409 are fixedly connected to the arc surface of the film removal gun 3. An insert rod 410 is slidably inserted into the inner surface of the U-shaped frame 409. Adjusting the position of the square frame 408 within the U-shaped frame 409 adjusts the distance between the two conical sleeves 402, thereby changing the flow rate. A first spring 411 is fitted onto the arc surface of the insertion rod 410. The two ends of the first spring 411 are fixedly connected to the surface of the retaining frame 409 and one end of the insertion rod 410, respectively. The first spring 411 confines the insertion rod 410 within a certain range, preventing it from falling off during use. Two torsion springs 412 are fitted onto the arc surface of the round rod 404. The two ends of the torsion springs 412 are fixedly connected to one side of the fixed block 403 and one side of the rotating block 405, respectively. The torque of the torsion springs 412 torsionals the distance between the two conical sleeves 402 to a commonly used range, simplifying operation.

[0026] Reference Figure 4 and Figure 5 As shown, specifically, the clamping device 5 includes three fixed frames 501, all of which are fixedly connected to the surface of the processing table 1. A rotating rod 502 is rotatably connected to the inner surface of each fixed frame 501. A gear 503 is fixedly connected to the arc surface of the rotating rod 502. A toothed plate 504 meshes with the surface of the gear 503. A moving block 505 is fixedly connected to one side of the toothed plate 504. A side plate 506 is fixedly connected to the surface of the processing table 1. A first anti-slip plate 507 is fixedly connected to one side of the side plate 506, and a second anti-slip plate 508 is fixedly connected to one side of the moving block 505. This increases friction and enhances the clamping force of the moving block 505 on the lithium battery cell body 2. Two guide frames 509 are fixedly connected to the surface of the processing table 1. A guide rod 510 is slidably connected to the inner surface of each guide frame 509, and one end of the guide rod 510 is fixedly connected to the moving block 505. The guide rod 510 positions the moving trajectory of the moving block 505, preventing it from shaking during movement.

[0027] Working principle: When the operator needs to adjust the dosage in the film removal gun 3 using the adjustment device 4, firstly, the insertion rod 410 is pulled to slide on the inner surface of the circular frame 409, and the first spring 411 is stretched. When the insertion rod 410 slides out of the inner surface of the circular groove of the square frame 408, the sliding square frame 408 slides on the inner surface of the circular frame 409. Under the support of the two setting blocks 406, the square frame 408 rotates on the arc surface of the setting rod 407. Under the support of the fixing block 403, the rotation... The moving block 405 begins to rotate on the arc surface of the round rod 404, the two conical sleeves 402 begin to rotate, the torsion spring 412 is compressed, and when the distance between the two conical sleeves 402 is adjusted to a suitable size, the insert rod 410 is released and slides on the inner surface of the circular frame 409. The insert rod 410 slides into the inner surface of the circular groove of the square frame 408, the first spring 411 rebounds, and the demeabilizing agent begins to flow out from the demeabilizing gun 3, flows through the fixed tube 401 to the surface of the lithium battery cell body 2, and demeabilizes it.

[0028] When the operator needs to use the clamping device 5 to clamp the lithium battery cell body 2, first place the lithium battery cell body 2 on the surface of the processing table 1 and place it on one side of the side plate 506 to abut against the first anti-slip plate 507. Then, rotate the rotating rod 502 to drive the gear 503 to rotate on the inner surface of the three fixed frames 501. The gear 503 meshes with the toothed plate 504, thereby driving the toothed plate 504 to move forward. Under the support of the guide frame 510 and the guidance of the guide rod 509, the moving block 505 is pushed forward to slide, thereby pushing the second anti-slip plate 508 to abut against the lithium battery cell body 2 tightly, and the surface of the lithium battery cell body 2 is removed. After the film removal is completed, rotate the rotating rod 502 to drive the gear 503 to rotate on the inner surface of the three fixed frames 501, and drive the toothed plate 504 to move backward. When the distance between the second anti-slip plate 508 and the first anti-slip plate 507 is easy to remove the lithium battery cell body 2, the rotating rod 502 can be stopped.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
