A space solar cell bonding robot

Abstract

A space solar cell bonding robot system which consists of a three-axis Cartesian coordinate's robot, coating device, bonding device, orientation plate, and control subsystem was studied. A method, which can control the thickness of adhesive layer on the solar cell, was put forward and the mechanism was designed. Another method which can achieve the auto-bonding between thin coverglass and the space solar cell was studied and realized. It produced no air bubble in the adhesives layer under the condition of no vacuum environment, and ensures the assembly dislocation ≤0. 1 mm. Compared to the conventional method, it has advantages such as no fragment exists, and no adhesives outflow onto the cover-glass and solar cells.
