Laser weakening machining equipment

Abstract

The invention belongs to the technical field of automobile industrial laser machining and provides laser weakening machining equipment. The laser weakening machining equipment comprises a technological control system, a laser device, a reflection focusing module, a sensor system and a workpiece fixing device. The technological control system is in control connection with the laser device, the sensor system and the workpiece fixing device. The workpiece fixing device is used for fixing and positioning a workpiece. The reflection focusing module is located on the horizontal side of a laser outlet of the laser device. The workpiece and the sensor system are sequentially located below the reflection focusing module. Lasers emitted by the laser device in the horizontal direction are reflected and focused through the reflection focusing module to be downward so as to machine the workpiece. The sensor system below the workpiece comprises a focus lens and a sensor. Due to the fact that the sensor is arranged below the workpiece, laser signals penetrating the workpiece are detected when the workpiece is machined, the system can monitor and store machining data of each hole on a weakening line in an on-line manner, and judge whether each hole is qualified or not, and the residual thickness precision of the weakening line is improved.

Description

technical field [0001] The invention belongs to the technical field of laser processing in the automobile industry, and in particular relates to laser weakening processing equipment. Background technique [0002] With the continuous development of the automobile industry and consumers' emphasis on safety, pursuit of comfort and desire for aesthetics, the application of integral airbag dashboards is becoming more and more extensive. [0003] The integral instrument panel needs to process a seamless airbag weakening line in the area where the passenger airbag explodes. The laser weakening process is to use the high energy of the laser to process the seamless airbag line. The laser generator focuses the generated laser in the range of about 0.2mm in diameter to form a high-energy laser beam. The laser beam passes through the The laser head hits the instrument panel in the form of fixed-frequency pulses, and the material at the focal point vaporizes rapidly after absorbing the ...
