[0003] The existing coating equipment will have a pre-coating module at one end, and will pre-coat on the pre-coating platform before coating the battery cell. The pre-coating allows the coating knife to better control the coating quality during subsequent coating. However, the existing technical solution requires cleaning the pre-coating platform after coating. The existing cleaning method uses manual wiping of the coating platform, and the coating knife is cleaned by another independent device. The pre-coating module and the coating knife cleaning module are separately arranged, and the two modules need to be cleaned separately, which makes the equipment occupy a large space and has a low integration.

[0004] Therefore, it is necessary to design an integrated pre-coating and cleaning device to solve the problems of large space occupied by existing coating knives and pre-coating platforms, low integration and low automation. Utility Model Content

[0031] In some embodiments, before coating the glass substrate, the coating knife is first moved to the pre-coating platform 1 for pre-coating. After the pre-coating is completed, the coating knife and the pre-coating platform 1 need to be cleaned.

After one reciprocating movement, it returns to the starting point, and then the nozzle 3 rinses the first scraper assembly 21 and the second scraper assembly 22; wherein, the pre-coating platform 1, the cleaning device 2 and the nozzle 3 are integrated in one main body, which reduces the space occupied compared to the split design, and at the same time, it is more efficient than manual wiping and rinsing.

[0032] like Figure 2As shown, in some embodiments, the pre-coating and cleaning integrated equipment also includes: a liquid holding tank 5; the pre-coating platform 1 is arranged in the liquid holding tank 5; the liquid holding tank 5 is provided with a waste liquid tank 51 and a coating knife immersion tank 52; wherein the width of the waste liquid tank 51 is greater than the sum of the lengths of the first scraper assembly 21 and the second scraper assembly 22; specifically, the pre-coating platform 1 is located in the middle of the waste liquid tank 51, and a distance is left between the four sides of the pre-coating platform 1 and the inner wall of the waste liquid tank 51, so that the first scraper assembly 21 and the second scraper assembly 22 can scrape the waste liquid into the waste liquid tank 51 during operation to prevent the waste liquid from flowing onto the coating platform and contaminating the table top.

[0042] In some embodiments, the process of wiping the coating knife and the pre-coating platform 1 is as follows: the cylinder 2321 first drives the lateral rod 24 to move out of the scraper accommodating position 53, and then the driver 2314 drives the screw rod 2311 to rotate, so that the slider 2312 drives the cylinder 2321 to move.

[0043] In summary, before coating the glass substrate with the pre-coating and cleaning integrated equipment, the coating knife is first moved to the pre-coating platform 1 for pre-coating. After the pre-coating is completed, the coating knife and the pre-coating platform 1 need to be cleaned. At this time, the driving mechanism 23 drives the transverse rod 24 to move transversely between the coating knife and the pre-coating platform 1, so that the second scraper assembly 22 set downward wipes the pre-coating platform 1, and the first scraper assembly 21 set upward wipes the coating knife. After one reciprocating movement, it returns to the starting point, and then the nozzle 3 rinses the first scraper assembly 21 and the second scraper assembly 22; the pre-coating platform 1 and the cleaning device 2 are integrated in one main body, which reduces the space occupied compared to the split design; in addition, the pre-coating platform 1, the cleaning device 2 and the nozzle 3 are integrated in one main body, which is more efficient than manual wiping and flushing.
