Description

Technical Field

[0001] The utility model belongs to the technical field of solar cell manufacturing, and in particular relates to a coating machine. Background Art

[0002] In the slit coating equipment used to manufacture solar cells, different thin films need to be formed on the surface of the cell substrate to achieve specific functions. At this time, a coating machine is required to coat the surface of the cell substrate and then crystallize the cell substrate to form a surface thin film. The existing coating machine is usually composed of a coating platform and a gantry. The cell substrate is placed on the coating platform, and the gantry sprays the coating liquid. When the coating platform moves, the liquid is applied to the cell substrate to complete the coating. However, when the existing coating platform moves, the cell substrate moves, which will cause the cell substrate to shake, so that the liquid cannot be evenly applied on the cell substrate, resulting in poor coating effect. In addition, the height of the coating platform is not adjustable, and the uneven surface of the coating platform affects the coating effect. In order to achieve the best coating effect, the coating machine equipment often needs to be replaced, resulting in reduced coating efficiency and quality.

[0003] Therefore, it is necessary to provide a coating machine with stable and efficient coating effect. Utility Model Content
