Description

TECHNICAL FIELD

[0001] The utility model relates to battery production equipment technical field especially relates to a vacuum dust absorption adsorption roller. BACKGROUND

[0002] The production process of composite current collector, pole piece and the like will produce waste scraps attached on the film surface, which not only affects the appearance, but also affects the subsequent processing. The traditional method for removing waste scraps includes mechanical scraping and electrostatic adsorption. The mechanical scraping method usually uses a metal brush or a scraper to remove the waste scraps on the film surface, which is simple to operate, but the contact mode of operation is easy to damage the film surface, and the removal of small particles is not complete. The electrostatic adsorption method uses a high-voltage power supply to generate an electrostatic field to attract waste scraps, so as to remove the waste scraps without damaging the film surface. However, the strength of the electrostatic field is difficult to control, and the energy consumption is high.

[0003] Based on the defects of the above two methods, the waste edge adsorption device disclosed in publication No. CN209831083U discloses an adsorption roller mechanism, which includes a fixed roller and a rotating roller. The rotating roller is sleeved on the fixed roller. The fixed roller has an adsorption end. The rotating roller has a through hole. The area corresponding to the adsorption end of the through hole is an adsorption area. When the adsorption area is away from the adsorption end, it is converted into a material removal area. In this way, the adsorption area is used to adsorb the waste scraps, and the waste scraps are continuously rotated to the material removal area by the rotating roller. The waste scraps are removed under their own gravity, which hardly damages the film surface and has the characteristics of low energy consumption. However, the material removal is realized by the self-weight of the waste scraps, which is easy to cause the situation that the waste scraps do not successfully remove the material and continue to rotate with the rotating roller to the corresponding adsorption end, thereby damaging the film surface, and the waste scrap removal efficiency is low.

[0035] In this way, one end of the film with debris is wound on adsorption roller 2, adsorption roller 2 rotates, and both dust absorption area 321 and adsorption area 311 are vacuumized, so that through hole 21 corresponding to adsorption area 311 can adsorb the film flat on the surface of adsorption roller 2, so that dust absorption area 321 on the front side can suck and collect the debris on the film surface through the corresponding through hole 21, so that efficient and complete removal of debris can be realized in the case of adsorption and dust absorption function in a small area with the rotation of adsorption roller 2, without damaging the film surface, and with the characteristics of low energy consumption and low cost.

[0036] It should be noted that the position, size of adsorption area 311 and dust absorption area 321 and the number and position of corresponding through hole 21 are set according to the adsorption and dust absorption requirements, and they are adjustable structures, not limited to only one.
