Scanning electron microscopy (SEM) was used to carry out macro and micro detection on the samples of soft bonding failure of aerial transparent parts. Combined with the observation results, a flexible force-sensing system was used to realize 2d and 3D imaging and data acquisition of the pressure distribution in the pressure process, and the relationship between the bonding strength and pressure of J-189 polyurethane adhesive was analyzed. The results show that there is a wide range of pressure out of tolerance in the pressure clamping process widely used in domestic industrial sectors. It will cause the debonding phenomenon of block and strip, etc. Finally, according to the analysis results, a pressure application scheme of using a manipulator automation device to replace the traditional mechanical fixture is proposed, which provides an improvement idea for improving the reliability and efficiency of the soft connection.
