Photovoltaic glass laser drilling equipment

Abstract

The utility model discloses laser drilling equipment for photovoltaic glass, belongs to the related technical field of photovoltaic glass processing, and aims to solve the problem that in the prior art, when the photovoltaic glass is drilled, generated thermal stress may cause microcracks to the wall of a hole. The microcracks can reduce the strength of the glass and prolong the service life of the glass, and in the subsequent use process, the microcracks can be possibly expanded under the action of stress or environmental factors, and finally the glass is broken. The novel laser drilling equipment comprises a workbench, an electric telescopic rod, a lifting plate and two heating plates, and the lower end of the lifting plate is fixedly connected with the two heating plates. Through the electric telescopic rod, the heating plate and the lifting plate, due to the fact that the lifting plate is made of heat conduction materials such as copper, the temperature of the lifting plate can be increased through the heating plate, the situation that the service life of photovoltaic glass is shortened due to microcracks in the follow-up use process is avoided, and the working quality of the punching equipment is improved.
