A Space Solar Cell Bonding Robot

研究了一种用于空间太阳电池封装的机器人系统.它包括三自由度直角坐标机器人、滴胶机构、封装机构、电池片及玻璃盖片的定位托盘、控制系统等.提出了控制电池片胶层厚度的连续滴胶方法与机构,以及一种能实现薄形抗辐照玻璃盖片和空间太阳电池的自动封装方法与机构.在无真空的环境条件下,使封装胶层内无气泡产生,并保证了封装边缘错位不大于0.1mm.与原有人工封装方法相比,没有碎片现象出现,盖片胶也不外溢、不污染玻璃盖片和电池片.

A space solar cell bonding robot was studied, which consists of a three-axis Cartesian coordinates robot, coating device, bonding device, orientation plate and control subsystem. 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 cover-glass and the space solar cell was studied and realized. It produces no air bubble in the adhesives layer under the condition of without vacuum environment and ensures the assembly dislocation ≤ 0.1 mm. Compared with the conventional method,it has such advantages that there is no fragment exists, and no adhesives outflows onto the cover-glass and (solar) cells.
