Description

Technical Field

[0001] The invention relates to the technical field of laser cladding, and in particular to a cladding head protective mirror drawer device with temperature display. Background Art

[0002] Corrosion of parts is the main cause of damage to mechanical equipment. The quality of the corrosion resistance of parts is directly related to the safe operation of mechanical equipment. Using laser to clad alloy powder on the surface of the workpiece is a recently developed anti-corrosion technology. The laser cladding head is one of the components of laser cladding and is the output unit of high-power laser. The protective lens is the last layer of protection for laser output and is also the most susceptible to dust and smoke pollution and burning. Under normal circumstances, the protective lens can still maintain room temperature after passing through the laser. After the light transmission capacity of the lens decreases, it will absorb part of the laser and reduce the laser pass rate. This part of the absorbed laser will cause the lens temperature to rise sharply and cause the lens to be damaged. If it is not discovered in time, it will cause greater losses and dangers. The focusing lens, collimating lens, and even optical fiber and laser will be damaged. However, the current laser cladding head has no effective method to detect the abnormality of the protective lens in time or there is no reasonable and consistent time to replace the protective lens, which hinders the development of laser cladding technology.

By innovatively setting the cladding head protective mirror drawer device with temperature display, the working condition of the protective mirror is monitored in real time and updated in real time on the display.
