Embodiment 1

[0018] figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention, which includes a total reflection mirror 1, an acousto-optic Q-switching switch 2, a semiconductor pump module 3, an output mirror 4, a beam expander mirror 5 and a 45° total reflection mirror arranged in sequence on the main optical path Mirror 6 is provided with a scanning vibrating mirror 7 on the reflection optical path of the 45 ° total reflection mirror 6, and a focusing lens 8 is provided on the reflection optical path of the scanning vibration mirror 7. The 45 ° total reflection mirror 6 is placed at an angle of 45 ° with the main optical path, The scanning galvanometer 7 is placed at an angle of 45° to the main optical path. The acousto-optic Q-switching switch 2 is a single-head acousto-optic Q-switching switch or a double-head acousto-optic Q-switching switch.

[0019] In this embodiment, the acousto-optic Q-switching switch is preferably a British Gucci double-head Q swi...

Embodiment 2

[0021] figure 2 It is a structural schematic diagram of Embodiment 2 of the present invention. The structure and principle of this embodiment are basically the same as Embodiment 1. The difference is that the main optical path between the semiconductor pump module 3 and the output mirror 4 is also provided with a second acousto-optic Q switch 9. In this embodiment, both the acousto-optic Q-switch and the second acousto-optic Q-switch use a British Gucci single-head Q switch. The GTPC-200 semiconductor pump module of Beijing Jitai Jiye is used, and the pump output power is 200 watts. Use an output mirror with a transmittance of 40% and double the beam expander. It adopts a high-speed laser scanning galvanometer for 1064nm wavelength and a 45° total reflection mirror with high reflection for 1064nm wavelength laser. The cavity length of the acousto-optic Q-switched solid-state laser composed of the total reflection mirror 1, the acousto-optic Q-switched switch 2, the semicon...

Abstract

The invention provides a portable-type laser cleaning head comprising a total reflector, an acousto-optic Q-switch, a semiconductor pumping module, an output mirror and a beam expander which are sequentially arranged on a main light path, wherein a scanning galvanometer is arranged in the output light direction of the beam expander, and a focusing lens is arranged on the reflecting light path of the scanning galvanometer. The laser output by the acousto-optic Q-switching solid laser device which is composed of the total reflector, the acousto-optic Q-switch, the semiconductor pumping module and the output mirror is expanded and shaped via the beam expander and then being incident on the scanning galvanometer; and the laser passing through the scanning galvanometer is focused on pollutants via the focusing lens to perform laser cleaning. According to the invention, the output power of laser is increased by means of acousto-optic Q-switching; and the main body of the laser device is placed in the laser cleaning head without a need of optical fibre transmission, so that the problems of low power, low monopulse energy, possibility of generating coupling loss during a transmission process, and easiness to damage transmission optical fibres of the present portable-type laser cleaner are solved.

Description

technical field [0001] The invention relates to a portable laser cleaning head, which is suitable for various types of portable laser cleaning machines. Background technique [0002] Laser cleaning is a new type of laser surface treatment technology. It uses a high-energy laser beam to irradiate the surface of the workpiece, so that the dirt, rust or coating on the surface evaporates or peels off instantly, and effectively removes the attachment or surface coating on the surface of the object at high speed, so as to achieve the process of cleaning the surface of the material. It does not require cleaning liquid or other chemical solutions, and has a wide range of dirt removal and applicable substrates. The cleaning process does not damage the surface of the substrate. Therefore, it is different from traditional chemical cleaning, mechanical brushing, fluid particle scouring, and ultrasonic cleaning. Compared with others, it has unique advantages, so it has become an irrepla...
