To promote the bonding quality and the automatic level of the solar cell assembly, according to the characteristic of the space solar cell bonding operation's process, an adhesive dispensing robot used for the bonding operation is studied in this article. And we put forward a way to continuously dispense adhesives, which can control the thickness of the adhesive layer on solar cell and even the position and volume of adhesives. It makes the thickness confined within 0.1 mm. This article also shows another approach which can achieve the auto-bonding between thin cover-glass and the space solar cell. It not only no longer produces air bubbles in the adhesives layer under the condition of non-vacuum environment, but also make sure the assembly dislocation is in the range of 0.1 mm. Compared with the conventional way, there is no fragment existing, and the adhesives no longer outflow onto the cover-glass and the solar cells.
