Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting devices, in particular to a novel focusing protection component. Background Art

[0002] With the development of social science and technology, my country's manufacturing industry is facing a transformation towards high-end and intelligentization. As a basic processing, the penetration rate of laser technology in various links of industrial production is also rising. Laser cutting is a technology that uses a high-power density fiber laser beam to irradiate the material to be cut, so that the irradiated part of the material vaporizes to form tiny holes, and as the fiber laser beam moves, the holes are continuously formed to complete the cutting of the material.

[0003] The application of laser in industry is becoming more and more mature. Common laser applications include laser cutting, laser welding, laser marking, laser rust removal, laser edge sealing and other fields. In the field of laser edge sealing, a focusing protection component is provided on the laser head, and a focusing protection drawer component is provided in the focusing protection component. The focusing protection drawer component can be pulled out in the cavity. A focusing protection lens component and a pan-seal are provided on the focusing protection drawer component. The pan-seal is provided at the front end of the focusing protection lens component. The thickness of the pan-seal plus the focusing protection lens component is greater than the thickness of the cavity. When the pan-seal is installed in the cavity, the pan-seal is squeezed. At the same time, the pan-seal elastically fits the focusing protection lens component to the inner wall of the cavity to fix the focusing protection lens. However, the existing structure makes it possible to push out the focusing protection lens component due to the effect of the pan-seal elasticity when taking out the drawer component. The focusing protection drawer component can only be pulled out by the operator holding the other side of the focusing protection lens component, but it may still cause the focusing protection lens component to fall off, and there is a risk of damage to parts, which brings inconvenience to the operator and is not conducive to improving the competitiveness of the enterprise.
