Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning equipment, in particular to a protective device. Background Art

[0002] Laser cleaning is a process that uses a high-energy-density laser beam to irradiate the surface of the workpiece to be cleaned, causing the dirt, rust or coating on the surface to evaporate or peel off instantly, thereby quickly and effectively removing the surface attachments or surface coatings of the cleaning object. Laser cleaning is a green cleaning method that does not require the use of any chemicals or cleaning fluids. The waste cleaned is basically solid powder. Laser cleaning can remove various types of contaminants on the surface without damaging the material surface, achieving a cleanliness level that cannot be achieved by conventional cleaning.

[0003] A laser cleaning protection device with patent application number 202320065748.4 cleans the workpiece on a rail-type laser cleaning machine and a light-transmitting plate, and weakens the reflected laser through the shielding of a protective cover, thereby greatly reducing the damage of the laser to people's eyes and effectively improving the protection effect. However, when in use, the protective cover is fixedly installed by a positioning slot frame. When taking and placing the workpiece, the light-transmitting plate needs to be disassembled as a whole, which is cumbersome to operate. At the same time, it is not convenient to clean and centrally store the waste residue powder remaining after cleaning inside the protective cover.

[0004] In the existing system, when laser cleaning is performed on workpieces, manual hands are inserted into the protective cover to pick up and place the workpieces. It is easy for the laser equipment to be not turned off during the pick-up and placement operations, which may cause direct contact between the operator and the laser beam, resulting in serious personal injury, and there are certain safety hazards.

[0005] Therefore, it is necessary to provide a new protective equipment to solve the above-mentioned technical problems. Utility Model Content
