Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production equipment, and in particular to an automatic glue-tearing device for a square aluminum shell of a lithium battery. Background Art

[0002] The square lithium battery is composed of several cells connected in series and parallel, and the square aluminum shell is a part of the square cell. The square cell is wrapped with a layer of protective film before drying, which is used to separate the square cells and block the impact of various faults of a single square cell on other cells to prevent "one failure leads to all failures". It can also be used to bundle the cell group to protect the appearance and provide insulation. This is an indispensable part of the production process of square lithium batteries.

[0003] During the production process, a layer of coating needs to be sprayed on the surface of the square aluminum shell to replace the traditional blue film process. The process of spraying the coating is to clean the outer surface of the square aluminum shell, spray the coating and dry it to form a protective film. The square aluminum shell is in a 'U' shape. In order to prevent impurities from penetrating into the interior of the square aluminum shell during the cleaning and spraying process, the outer surface of the square aluminum shell needs to be sealed. Usually, a fixture matching the shape of the square aluminum shell is used to seal the gap, and then a waterproof tape is applied for sealing. The waterproof tape is torn off after the spraying is completed.

[0004] Traditionally, the waterproof tape of a square aluminum shell is peeled off manually. Since the waterproof tape is cured at high temperature after spraying, it is not easy to peel off. Manual peeling can easily damage the coating, which has the disadvantages of high risk, high labor intensity, high labor cost, and low output.

[0005] Therefore, how to provide an automatic glue peeling device for lithium battery square aluminum shells to improve the quality and efficiency of square aluminum shell peeling and reduce the cost of peeling has become a technical problem that needs to be solved urgently.

[0142] Working principle of the present invention:

[0143] The PLC8 controls the incoming material conveying module 2 to convey the square aluminum shell 91 fixed with the jig 92 by the waterproof tape 93. When the in-place detection sensor group 7 senses that the conveyance is in place, the transplanting module 4 is controlled to transplant the square aluminum shell 91 to the centering and clamping part 34 of the rotating material distribution module 3. During the transplanting process, the jig 92 faces downward and is positioned by the positioning pin 3421.

[0144] The PLC8 controls the rotating disk 32 of the rotating material distribution module 3 to rotate so that the square aluminum shell 91 rotates to the working position of the glue tearing module 5, and limits the self-rotation of the square aluminum shell 91 through the latch anti-rotation part 36; the PLC8 controls the glue tearing part 54 to press on the waterproof tape 93 of the square aluminum shell 91 to perform the glue-removing action, and after shoveling out the waterproof tape 93, it is clamped by the elastic clamping claw 543 of the glue tearing part 54, and then the restriction on the square aluminum shell 91 is released by the latch anti-rotation part 36, and the square aluminum shell 91 is controlled to rotate by itself through the aluminum shell rotating part 35 to release the waterproof tape 93, and the released waterproof tape 93 is wound around the glue tearing and wrapping disk through the glue tearing part 54.

[0145] After the glue peeling is completed, the square aluminum shell 91 is controlled to rotate to the initial position through the aluminum shell rotating part 35, and the rotation of the square aluminum shell 91 is limited by the latch anti-rotation part 36. The square aluminum shell 91 with glue peeling is transplanted to the incoming material conveying module 2 for discharging through the transplanting module 4, and the remaining jig 92 is transplanted to the jig reflux module 6 for reflux.

[0146] In summary, the advantages of the present invention are:

Compared with the traditional manual glue peeling, the quality and efficiency of the square aluminum shell glue peeling are greatly improved, and the glue peeling cost is greatly reduced.

[0148] 2. The material conveying module includes four material conveying lines for feeding and discharging the square aluminum shell, which greatly improves the transmission efficiency of the square aluminum shell and thus greatly improves the glue tearing efficiency of the square aluminum shell.

[0149] 3. By setting a rotating material distribution module including a first rotating motor, a rotating disk, an anti-dumping device, a centering and clamping device, an aluminum shell rotating device and a latch anti-rotation device, the centering and clamping device is used to place a square aluminum shell. The rotating disk is driven to rotate by the first rotating motor, so that the square aluminum shell placed on the centering and clamping device can be linked to rotate. The placement angle of the square aluminum shell can be adjusted as needed through the aluminum shell rotating device, so that the square aluminum shell can complete the glue peeling operation during the rotation process. The latch anti-rotation device is set to limit the centering and clamping device, which can prevent the square aluminum shell from rotating during the rotation of the rotating disk. Combined with the anti-dumping device, the square aluminum shell can be prevented from tipping over, thereby ensuring the stability of the glue peeling process, thereby greatly improving the glue peeling quality.

[0150] 4. By setting up the anti-dumping device including a clamping motor, a suction cup, and a vacuum generator, the clamping motor drives the suction cup to clamp the square aluminum shell, and then the vacuum generator is used to evacuate the suction cup, which greatly improves the stability of the square aluminum shell suction and effectively prevents the dumping of the square aluminum shell.

[0152] 6. By setting up the glue peeling module including the X-axis transplanting unit, the Y-axis transplanting unit, the rotating unit and the glue peeling unit, the position and angle of the glue peeling unit can be flexibly adjusted through the X-axis transplanting unit, the Y-axis transplanting unit and the rotating unit, which greatly improves the flexibility of the glue peeling.

[0153] 7. By setting up the glue tearing device including the mounting seat, the clamping claw cylinder, the elastic clamping claw, the shrinking cylinder, the rubber wrapping plate, the push plate cylinder and the push plate, the clamping claw cylinder can clamp the waterproof tape through the elastic clamping claw, the shrinking cylinder can wrap the waterproof tape through the rubber wrapping plate, and the push plate cylinder can remove excess glue through the push plate, which greatly guarantees the glue tearing quality.

[0154] 8. By setting the elastic clamp including the fixing part, the length adjustment nut, the bushing, the telescopic rod, the rubber scraper head and the spring, the rubber scraper head will compress the telescopic rod when contacting the square aluminum shell and reset under the elastic force of the spring, that is, the rubber scraper head will flexibly contact with the square aluminum shell, thus avoiding damage to the square aluminum shell during the rubber peeling process, and greatly ensuring the quality of the rubber peeling.
