Automatic coating and fastening robot of space solar module to solar panel substrate

摘要

Purpose This paper aims to propose an automatic coating and fastening robot (ACFR) of space solar module (SSM) to solar panel substrate. Design/methodology/approach Describes the detailed manufacturing process of space solar cell arrays (SSCA), and gives an ACFR for SSM. Designs an automatic coating and fastening mechanism and a control system. Furthermore, establishes the “zigzag”, the “umbrella” and the Voronoi‐based “ring” path models of the coating path using syringes. Findings The robot is effective for the bubble‐free manufacture of SSCA in nonvacuum environment. The robot with three coating path models can control the thickness of adhesive layer on the back of SSM, and the fastening force to the solar panel substrate with high productivity. The experimental results have proved the validity of this robot in the SSCA's manufacture. Practical implications The robot as a novel industrial equipment can improve the product quality and the reliability of SSCA to a certain extent. Originality/value The robot has potential applications in the SSCA assembly. It will change the traditional handworking status in the future.
