Description

Technical Field

[0001] The utility model relates to a scraper device for cleaning rollers in the rolling process of lithium-ion batteries, belonging to the technical field of battery production. Background Technique

[0002] During the rolling process of lithium-ion battery production, a certain amount of dust and impurities often adhere to the surface of the rollers. If not cleaned in time, it will seriously affect the rolling quality of the electrode sheets, resulting in problems such as uneven surface and thickness of the electrode sheets, and further affecting the overall performance of the battery.

[0003] Currently, the commonly used method for cleaning rollers in the industry is to install a scraper device on the rollers. However, the existing scraper devices have the following problems in the use process:

[0004] 1. When the scraper is worn or needs to be replaced, it usually requires manual operation in a fixed fixture. This process not only takes a long time, increasing the downtime of the production line, but also manual operation is accompanied by certain safety risks. For example, improper operation may cause injuries to personnel.

[0005] 2. When installing the scraper device, due to the lack of an accurate positioning mechanism, it often relies on manual experience and repeated debugging to determine the appropriate installation position. This method is not only inefficient but also prone to tight or loose gaps between the scraper and the roller due to human errors.

[0006] A too-tight gap may scratch the surface of the roller, causing permanent damage. The scratching of the roller by the scraper not only directly damages the service life of the roller but also may cause the scratched area to become the starting point of sticking to the roller, further exacerbating the sticking phenomenon. Sticking to the roller not only reduces the product quality but also may affect the normal progress of subsequent production processes.

[0007] 3. A too-loose gap cannot effectively remove the dust on the roller, affecting the rolling effect. If the left and right positions are uneven when it is too loose, it will directly lead to problems such as sticking to the roller or inconsistent left and right thicknesses of the rolled electrode sheets, which will directly affect the uniformity and consistency of the battery. Content of the Utility Model

[0008] To solve the problems in the background technique, the utility model provides a scraper device for cleaning rollers in the rolling process of lithium-ion batteries.

[0010] A distance measuring sensor is provided on each synchronous motor, and the distance measuring sensor is signal-transmission connected to the controller.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model realizes the rapid and safe replacement of the scraping blade through automatic operation, shortens the replacement time, reduces the risk of manual operation, reduces the production cost, and improves the product yield.

[0013] 2. The utility model ensures accurate positioning when the blade is installed and automatically adjusts the gap with the roller through the linkage of the distance measuring sensor and the synchronous motor, avoiding problems such as roller scratches or incomplete cleaning caused by improper manual adjustment.
