Background

Laser radar detection technology has been widely used in the fields of unmanned driving, robots, mechanical ranging and the like. The laser radar window is generally a protection window of a solid laser radar or a semisolid laser radar, most of the laser radar window is of a sheet arc structure, the material is basically formed by injection molding of black polycarbonate (PC material) which only transmits infrared light, and in order to obtain better window surface hardness and better optical characteristics, the surface hardening treatment and the reflection reduction coating of the radar window after injection molding are basically increased. Most of the time when the laser radar window is assembled is combined with the hardware support by adhesive. The laser radar component has higher requirements on the bonding strength and the air tightness of the bonding process. But the surface energy of the radar window is greatly reduced by the hardening process and the coating process of the radar window. The bonding force of the viscose is seriously affected. Therefore, in the industry, the viscose groove of the radar window is filled in advance when injection molding is adopted, and the glue groove is processed by adopting a CNC (computer numerical control) processing technology after hardening and coating, so that a hardening film layer and an antireflection film layer are not formed on the glue groove, and the surface of the glue groove and glue can be ensured to have enough adhesive force.

But the specification of gluing the groove needs strict control, it is too shallow too deeply in gluey groove all can lead to the viscose bad, intensity and airtight after the bonding all probably receive the influence, so need detect gluing the groove, current radar window is according to complete machine and optical design demand, the molding is heterotypic cambered surface almost, the degree of depth and the test of tank bottom thickness of gluing the groove on the heterotypic cambered surface of CNC processing are very difficult, detection efficiency is very low, be difficult to realize the short-term test of production, the control of giving batch production brings very big puzzlement.
