Description

Technical Field

[0001] The utility model relates to the technical field of battery sheet preparation, in particular to a battery sheet preparation device. Background Art

[0002] The production of battery cells is mainly divided into several processes such as raw material preparation, battery cell preparation, and battery cell testing. The main raw materials of battery cells include silicon wafers, phosphocitric acid solution (used to corrode silicon wafers), purified water, etc. During the preparation process, these raw materials need to be strictly screened and tested to ensure that the quality of the raw materials meets the requirements. Then comes the battery cell preparation process. The silicon wafer is placed in the corrosion tank and corroded with phosphocitric acid solution to remove impurities on the surface of the silicon wafer. The corroded silicon wafer is then placed in the cleaning tank and cleaned with purified water to remove residual solution and impurities on the surface of the silicon wafer. This is the preparation process for the battery cell. The preparation device will be used during the preparation. The common battery cell preparation devices on the market have weak storage components that carry silicon wafer preparation, which are easily deformed after long-term use and have a limited service life. In the process of the storage component controlling the silicon wafer to move from the corrosion tank to the inside of the cleaning tank, liquid (phosphocitric acid solution) will drip and drip onto the operating desktop, which will need to be wiped laboriously later.
