Laser cleaning equipment lens and laser cleaning equipment

Abstract

The invention belongs to the field of laser cleaning, and particularly relates to a laser cleaning device lens and a laser cleaning device. The laser cleaning device lens can zoom and accurately forman image within the large size, and is compact in structure, small and portable. A lens outer shell is provided with a hole allowing laser to pass through and is fixedly connected to the upper end ofthe outer side of a base; a chute is formed in the upper surface of the baser and penetrates through the upper surface of the base; the length of the chute is smaller than that of the base; a convex lens base is in sliding connection with the chute; the lower end of the convex lens base is located on the inner side of the base and is fixedly connected to a lens focusing device; the lens focusing device is fixedly connected to the inner side of the base; a galvanometer base is fixedly connected to the upper end of the outer side of the base; a laser sensor is fixedly connected to the base; thegalvanometer base is fixedly provided with a galvanometer; a convex lens is fixed to the convex lens base; and the convex lens base is located at the output end of the galvanometer base, so that the laser passes through the galvanometer firstly and then passes through the convex lens.

Description

technical field [0001] The invention belongs to the field of laser cleaning, and more specifically relates to a lens of laser cleaning equipment and laser cleaning equipment. Background technique [0002] The precision of laser cleaning is high, and the corresponding problem is that the ideal cleaning effect can only be obtained in a very narrow range near the focus of the output laser. The existing laser cleaning equipment has good adaptability to some flat surfaces, but for uneven The metal surface cleaning effect is not good. [0003] For such defects, there are currently two solutions as follows: 1. Add a variable-focus liquid zoom lens to the optical path to achieve zooming; 2. Change the height of the cleaning platform to adjust the distance between the workpiece to be cleaned and the lens. A Chinese invention patent for an automatic zoom laser cleaning head device and its cleaning method, patent number 201710744791.2, discloses a device that adds a zoomable liquid zo...

AI Technical Summary

Problems solved by technology

[0004] If the distance of the cleaning platform is adjusted, it is not suitable for small portable equipment. Small equipment may not be equipped with too large or even no cleaning platform. For the cleaning of parts of large non-detachable equipment, the laser cleaning equipment is often fixed at a specific position for cleaning. The cleaning platform cannot be moved

For liquid zoom lenses, the requirements for the lens are too high, and the conditions of use are limited
