Description

Technical Field

[0001] The utility model relates to the field of solar cell manufacturing, in particular to a mechanical arm and a texturing and cleaning device. Background Art

[0002] The first process equipment used in solar cell manufacturing is the texturing and cleaning equipment, which is mainly used to remove impurities, form a velvet surface through acid and alkali corrosion, and clean silicon wafers, thereby reducing the reflectivity and increasing the light absorption rate of solar cells. Since the corresponding texturing and cleaning process is corrosive, engineering plastics (such as polyetheretherketone PEEK or polypropylene PP) are generally used to manufacture the main components of the texturing and cleaning equipment. The robotic arm of the texturing and cleaning equipment is responsible for transferring the silicon wafer carrier frame or flower basket between different medium slots. The materials of the main mounting components and fasteners are mainly engineering plastics.

[0003] Since the mechanical arm of the texturing and cleaning machine operates at a high frequency, the fasteners (such as bolts) made of engineering plastics may become loose, causing the hanging plate to deviate from its original position, thus affecting the mechanical arm's accurate lifting of the silicon wafer basket.

[0004] Therefore, how to provide a robotic arm and a velvet cleaning device to improve the stability of the robotic arm's hanging plate and the accuracy of the robotic arm's transportation has become a technical problem that needs to be solved urgently in the industry. Utility Model Content
