Portable laser cleaning machine facilitating automatic focusing

Abstract

The portable laser cleaning machine comprises a cabinet body, a field lens is arranged at one end of a cleaning head shell and communicates with the interior of the cleaning head shell, a fixing base is arranged at the bottom of the inner surface of the cleaning head shell, and a laser gun head is arranged at the top of the fixing base; a movable base is slidably connected to the position, between the field lens and the fixed base, of the bottom of the inner surface of the cleaning head shell, a focus lens is arranged at the top of the movable base, and a fixed block is arranged at the position, on one side of the field lens, of the bottom of the inner surface of the cleaning head shell. A distance sensor is arranged at one end of the field lens on the outer surface of the cleaning head shell. The device has the beneficial effects that the device is reasonable in design, simple and stable in structure and high in practicability; the problems that the focal length of an existing laser cleaning machine is fixed, when the laser cleaning machine is held by hand, the shaking range of an arm exceeds the laser focusing range, laser energy is not focused, and the laser cleaning efficiency and the cleaning smoothness are greatly reduced are solved.

Description

technical field [0001] The invention relates to the technical field of laser cleaning machine equipment, in particular to a portable laser cleaning machine for automatic focusing. Background technique [0002] There are various cleaning methods in the traditional cleaning industry, most of which use chemical agents and mechanical methods for cleaning. Today, as my country's environmental protection laws and regulations are becoming more and more stringent, and people's awareness of environmental protection and safety is increasing, the types of chemicals that can be used in industrial production cleaning will become less and less. Laser cleaning has the characteristics of non-grinding, non-contact, non-thermal effect and applicable to objects of various materials, and is considered to be the most reliable and effective solution. At the same time, laser cleaning can solve problems that cannot be solved by traditional cleaning methods. The focal length of the existing laser ...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the focal length of the existing laser cleaning machine is fixed, and when the hand-held laser cleaning is performed, the shaking range of the arm will exceed the laser focusing range, causing the laser energy to be out of focus, greatly reducing the laser cleaning efficiency and cleaning smoothness. And provide a portable laser cleaning machine for auto focus
