[0044] In the related art, the screen plate assembly in the battery film pasting equipment is used to adsorb film patch accessories and facilitate film pasting and rolling. Bubbles are easily generated during the rolling and pasting process of the battery, which affects the film pasting quality.

[0045] In order to solve the above technical problems, with reference to Figure 1 The embodiment of the application provides a screen plate assembly 100, which comprises a first screen plate 110, a second screen plate 120, a first elastic sheet 130 and a second screen mesh 140.

[0046] Specifically, combined with Figure 2 and Figure 3As shown, the first mesh plate 110 is provided with a first opening 111 and a plurality of air holes 112, the number of air holes 112 can be one or more, not specifically limited here. One side of the second mesh plate 120 is connected with the first mesh plate 110, and the second mesh plate 120 is provided with a second opening 121 corresponding to the first opening 111; the first elastic sheet 130 is arranged between the first mesh plate 110 and the second mesh plate 120; the second mesh screen 140 is connected with the side of the second mesh plate 120 away from the first elastic sheet 130, and a gap is formed between the second mesh screen 140 and the first elastic sheet 130; the second mesh screen 140, the first elastic sheet 130 and the second mesh plate 120 together form a negative pressure space 150, any air hole 112 is in communication with the negative pressure space 150, the air hole 112 of the first mesh plate 110 is used to connect the air extraction device, the second mesh plate 120 is connected and installed through the first elastic sheet 130 and the first mesh plate 110, the second mesh screen 140 is connected with the side of the second mesh plate 120 away from the first elastic sheet 130, and there is a gap between the second mesh screen 140 and the first elastic sheet 130, the second mesh screen 140, the first elastic sheet 130 and the second mesh plate 120 form a negative pressure space 150 to generate negative pressure for adsorbing the film patch auxiliary material, the film patch auxiliary material is attached to the side of the second mesh screen 140 away from the second mesh plate 120, the second opening 121 corresponds to the position of the battery, the film patch auxiliary material is placed close to the battery, the glue rolling part 324 rolls and presses the first elastic sheet 130 through the position of the first opening 111, extrudes the negative pressure space 150 to make the first elastic sheet 130 abut against the second mesh screen 140, so that the film patch auxiliary material of the second mesh screen 140 is pasted on the surface of the battery in the form of rolling and pressing, preventing the film patch auxiliary material from being attached to the battery to generate bubbles.

[0047] In this embodiment, the negative pressure space 150 is used to form a vacuum environment by air extraction, the negative pressure space 150 can be realized by an air extraction device, the air extraction device extracts air through the air hole 112, the pressure inside the negative pressure space 150 is lower than the external pressure, the air pressure in the vacuum environment is much lower than the standard atmospheric pressure, and the interference of gas molecules in the vacuum environment is reduced, preventing bubbles from being generated during the battery film pasting process.

[0048] When the battery film pasting operation is performed by the screen assembly 100, the suction device is connected to the screen assembly 100 through the air hole 112, the screen assembly 100 is moved to the film auxiliary material, and the film auxiliary material is adsorbed by the second screen 140. The screen assembly 100 moves the film auxiliary material to the position on the surface of the battery. Since the negative pressure space 150 is formed between the first elastic sheet 130 and the second screen 140, when the first elastic sheet 130 is rolled by the rolling glue piece 324, the first elastic sheet 130 can be deformed towards the second screen 140, so that the first elastic sheet 130 abuts against the second screen 140, and the film auxiliary material is attached to the surface of the battery by compressing the negative pressure space 150.

[0049] Further, the first elastic sheet 130 is a first screen, and the first screen is coated with optical glue, so as to form a sealing structure, so that the second screen 140, the first elastic sheet 130 and the second screen 120 can constitute the negative pressure space 150, and the negative pressure space 150 can adsorb the film auxiliary material through the air holes of the second screen 140. Illustratively, the second screen 140 includes an adsorption part and a sealing part. The adsorption part is used to adsorb the film auxiliary material, and the sealing part is coated with optical glue to seal. When the adsorption part adsorbs the film auxiliary material, the sealing part is in a sealing state to avoid the negative pressure space 150 from leaking or deflating.

[0050] It can be understood that the battery film pasting refers to the process of attaching a layer of film auxiliary material to the surface of the battery. The film auxiliary material can be an insulating film or a protective film, etc. The screen assembly 100 is used to more accurately control the position of the film and improve the pasting quality. The screen assembly 100 applies a vacuum suction force to form a negative pressure to adsorb the film auxiliary material, and accurately places the film auxiliary material on the surface of the battery. The vacuum environment helps to remove the air between the film and the battery, reduces the generation of air bubbles, and ensures the accuracy and consistency of the film auxiliary material in the pasting process.

Correspondingly, the first mounting hole 113 and the second mounting hole 122 are correspondingly arranged to connect the first screen plate 110 and the second screen plate 120. For example, the first mounting hole 113 and the second mounting hole 122 can fix the position of the first elastic sheet 130. The first elastic sheet 130 is located between the first screen plate 110 and the second screen plate 120. When the glue rolling part 324 rolls the first elastic sheet 130, the offset or sliding of the first elastic sheet 130 is reduced.

[0053] Optionally, in combination with Figure 2 and Figure 3 As shown, the number of the air holes 112 is multiple, and the multiple air holes 112 are arranged around the first elastic sheet 130 on the first screen plate 110. Further, the air holes 112 are arranged through the first screen plate 110, that is, the air holes 112 can extend to the position of the first elastic sheet 130, so as to facilitate the air extraction of the negative pressure space 150 by the first elastic sheet 130.

[0054] In an embodiment, the screen plate assembly 100 further comprises a sealing member 160, which abuts between the first elastic sheet 130 and the second screen plate 120. When the second screen cloth 140, the first elastic sheet 130 and the second screen plate 120 form the negative pressure space 150, the air leakage or air leakage from the position of the first elastic sheet 130 during air extraction is reduced, and the sealing performance of the screen plate assembly 100 is improved. Further, the sealing member 160 is enclosed on the side of the first elastic sheet 130. For example, the material of the sealing member 160 can be elastic rubber, such as nitrile rubber, silicone rubber, ethylene-propylene rubber or natural rubber, etc., which has better sealing performance and durability, and will not be described here.
