It has good light transmission, moisture resistance and PID resistance, etc. It can effectively protect the battery and improve the performance and durability of the module.

[0003] However, the film may arch abnormally after laying, which may cause hidden cracks in the battery before lamination and packaging, and also affect the image acquisition quality of the overlay welding machine, increase the production cost and affect the production efficiency. After lamination and packaging, the arch of the film may cause short circuit of the battery string and parallel string, affect the filling uniformity and buffering protection effect, and in severe cases, may cause edge delamination and negative impact on moisture resistance and PID resistance, reducing the service life of the module.

[0033] Please refer to Figure 1 An embodiment of the present application provides a scraping device for solving the arching of the adhesive film laying, which comprises a gantry support, a position adjusting structure 6, a connecting structure 7 and a scraper 8.

[0034] Specifically, the gantry support comprises a cross beam 1 and two support beams 2 vertically arranged at both ends of the cross beam 1, respectively.

[0035] In some embodiments, the gantry support further comprises a base 3 arranged at the bottom of the support beam 2 and a roller 4 mounted at the bottom of the base 3.

[0036] In some embodiments, the roller 4 is provided with a locking piece 5. The locking piece 5 can fix the position of the roller 4. In the present scheme, the roller 4 and the locking piece 5 are both common components in the prior art. The present scheme does not make special settings for them, but only calls for the conventional technology to realize the overall movement function. By setting the gantry support as a movable support, the angle and position of the scraper 8 relative to the adhesive film can be adjusted, thereby improving the working efficiency and scraping quality.

[0037] The position adjusting structure 6 is fixed at one end of the middle part of the cross beam 1 and can be elongated or shortened in the height direction.

[0038] In some embodiments, the position adjusting structure 6 is a telescopic air cylinder. It is a conventional structure and will not be repeated here.

[0039] The connecting structure 7 is fixed at the other end of the position adjusting structure 6.

[0040] In some embodiments, the connecting structure 7 comprises a fixed strip and a fixing member, and the scraper 8 is connected to the fixed strip through the fixing member. The fixing member is a bolt. In detail, the shape of the fixed strip is matched with the shape of the scraper 8.

[0041] In some embodiments, a reinforcing rib 9 is formed on the side edge of the scraper 8 connected to the fixed strip, and the reinforcing rib 9 extends along the length direction of the scraper 8.

[0042] In some embodiments, the fixed strip is recessed inward from the bottom to form a plug-in slot for accommodating part of the scraper 8. This further improves the structural stability of the scraper 8 after being assembled with the positioning structure 6.

[0043] The scraper 8 is detachably connected to the positioning structure 6 through the connecting structure 7, and the length direction of the scraper 8 is arranged in the horizontal direction. The scraper 8 comprises a first plate body 81 and a second plate body 82 which are independent of each other, and the length directions of the first plate body 81 and the second plate body 82 are not horizontal and not parallel.

[0044] In some embodiments, an included angle is formed between the first plate body 81 and the second plate body 82.

[0045] In some embodiments, the first plate body 81 and the second plate body 82 are arranged in an "eight" shape structure.

[0046] In detail, in the length direction of the cross beam 1, the first plate body 81 and the second plate body 82 are symmetrically arranged on both sides of the positioning structure 6. In the moving direction of the scraper 8 relative to the rubber film, the included angle between the first plate body 81 and the second plate body 82 is greater than or equal to 90 degrees and less than or equal to 270 degrees. Thus, the situation that the force directions are too consistent due to the close of the first plate body 81 and the second plate body 82 can be limited or reduced, thereby improving the stability of the leveling device. This design can make the applied force more evenly distributed on the rubber film surface, thereby further avoiding the deformation and deviation of the rubber film during movement.

[0047] By using the above technical solutions, the application has the following beneficial effects compared with the prior art:

[0048] The leveling device of the application sets the scraper into a structure of a first plate body and a second plate body which are independent of each other, the length direction of the scraper is arranged in the horizontal direction, and the length directions of the first plate body and the second plate body are not horizontal and not parallel. In this way, the first plate body and the second plate body can perform leveling operation on the rubber film from different angles, taking into account the arching of the long side and the arching of the short side of the rubber film, solving the problem that the single-direction leveling of the rubber film by a horizontal scraper in the prior art easily leads to deviation of the rubber film, and making the leveling operation on the rubber film more effective and efficient.

[0049] Finally, it should be noted that the above are only preferred embodiments of the present application and are not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
