Description
Technical Field
[0001] The utility model relates to the technical field of battery cell purge devices, in particular to a battery cell purge device. Background Art
[0002] Screen printing is a core process in the manufacturing process of solar cells. Screen printing is mainly used for forming battery electrodes. It uses the basic principle that the mesh of the graphic part of the screen is transparent to the slurry, while the mesh of the non-graphic part is not transparent to the slurry. When printing, pour the slurry at one end of the screen, and use a scraper to apply a certain pressure on the slurry part of the screen while moving toward the other end of the screen. The slurry is squeezed from the mesh of the graphic part by the scraper to the substrate to form the required pattern.
[0003] During the production process of solar cells, foreign matter such as dust and debris may fall on the surface of the cell. These foreign matter stick to the surface of the cell and are extremely destructive to the stencil during printing. At the very least, it may block the stencil or even cause the stencil to explode, seriously affecting the service life of the stencil, product yield and output per unit time, and increasing production costs.

The wind knife device can generate high-speed airflow to clean foreign matter on the surface of the cell, thereby ensuring the cleanliness of the surface of the cell. Through the combination of the brush device and the wind knife device, foreign matter, debris and dust on the surface of the cell can be effectively removed, which helps to reduce the risk of screen exposure in the photovoltaic cell system.
[0021] The angle of the purge air knife can be adjusted by setting the rotating device. The operator can adjust the direction of the airflow from the air nozzle as needed to ensure that the purge airflow covers the entire surface of the battery cell, thereby improving the cleaning efficiency.
