Handheld laser gun head capable of adjusting light spot

Abstract

The invention provides a handheld laser gun head capable of adjusting a light spot. A collimating lens is mounted on a collimating lens base, the collimating lens base is inserted into a gun head bodythrough a through hole, and therefore, the collimating lens base can be taken out conveniently for replacing the collimating lens. The handheld laser gun head is further provided with a fixed plate and a sleeve, so that a moving spray nozzle can be fixed through the fixed plate and the sleeve in a moving process of the nozzle, and the spray nozzle cannot shake; and according to the handheld lasergun head, a first wedge lens is mounted in an inner rotor, a second wedge lens is mounted in an outer rotor, the outer rotor is adjusted to rotate relative to the inner rotor, the first wedge lens and the second wedge lens are enabled to rotate relatively, different angle differences are produced between the first wedge lens and the second wedge lens, a refraction angle of a light path is changed, movement of the light spot can be realized, then the size of the light spot is changed, and multiple welding technological requirements can be met.

Description

technical field [0001] The invention relates to the technical field of laser processing equipment, in particular to a hand-held laser gun head with adjustable light spot. Background technique [0002] At present, laser applications in the market are becoming more and more widely used, among which laser welding is particularly prominent. At present, the working principle of the existing laser gun head is that the laser beam is collimated by the collimator mirror, injected into the wedge mirror, and then passed through the focusing lens and the protective lens. Finally, the workpiece is laser processed through the nozzle. However, the collimating mirror in the current laser gun head is fixed in the laser gun head, which makes it inconvenient to replace the collimating mirror. Based on this, it is necessary to modify the existing laser gun head to improve. Contents of the invention [0003] In view of this, the present invention proposes a hand-held laser gun head with adjus...
