This invention discloses an apparatus and method for preparing composite thin films for solar cells. The apparatus includes a lower conveying mechanism, a middle coating mechanism, and an upper adsorption mechanism. A friction mechanism generates static electricity on the surface of a lifting slide to adsorb the thin film. A cutting blade cuts the film to be processed, which is then transferred to the lifting slide surface by a film suction cup. An internal electric cylinder pushes the film off and onto a conveyor belt for automatic unloading. The method includes: electrostatic preparation, lifting slide resetting, film cutting, film adsorption and transfer, film unloading and conveying, and end clamping preparation. This invention achieves automatic cutting, electrostatic adsorption, transfer and bonding, and continuous conveying of the thin film through an integrated design, improving the efficiency and positioning accuracy of thin film composite preparation, and is suitable for the automated production of solar cell materials.

This invention discloses an automatic planning method and system for spraying paths of 3D workpieces based on visual point clouds, specifically relating to the field of automatic spraying path planning technology. By constructing a spraying space coupling description set and a spraying deployment constraint index, the method achieves a quantitative characterization of the degree of restriction of spraying space in different surface areas. Combined with the safety margin of spraying distance and the adjustable range of spray gun posture, a physical accessibility assessment quantity for spraying is formed, which automatically divides the spraying area into a stable spraying area, a restricted spraying area, and a physically unsprayable area. Thus, in the path generation stage, differentiated strategies such as continuous spraying, segmented compensation, and path reconstruction are adopted for different areas, which significantly improves the coating coverage integrity, thickness consistency, and process reliability of complex 3D workpieces in the actual spraying process. It also enhances the system's adaptability to structural complexity and working condition changes in real coal mining machinery spraying sites and reduces the risk of manual repair and rework.

First, the raw material variety is diversified. Second, most of the impurities on the surface of the raw material can be removed. Third, inert gas is introduced into the inner cavity of the extrusion cylinder, and the air in the inner cavity of the extrusion cylinder and the inner cavity of the forming die is discharged to prevent the metal from being oxidized. Fourth, the raw material is softened first and then extruded, and the pressure of each extrusion is reduced through multiple extrusions, thereby improving the processing reliability. Fifth, multi-stage feeding is realized, the technical problems of uneven feeding and insufficient feeding are solved, and the yield is increased. Sixth, the piston body extrudes the material to be formed in the extrusion direction L2, and the cutting edge of the scraper cuts off the softened raw material entering the material bin section from the discharge port of the feeding structure, thereby reducing the resistance received by the extrusion device. Seventh, the forming die is replaceable.
