Description

Technical Field

[0001] This invention relates to the field of laser cleaning technology, specifically a backpack-type laser cleaning device. Background Technology

[0002] Laser cleaning is a new technology based on the interaction between laser and matter, effectively removing contaminants and deposits from object surfaces. Compared to traditional cleaning methods, laser cleaning offers advantages such as non-contact operation, no damage to substrates, precise cleaning, environmental friendliness, and online operation. It is particularly suitable for high-speed online cleaning of designated areas. Laser cleaning uses laser as a medium, achieving the removal of contaminants through the interaction of light and matter. Conventional physical cleaning methods cannot meet the requirements for high cleanliness, and while ultrasonic cleaning has good cleaning effects, it is ineffective at removing submicron-sized contaminants. Furthermore, the size of the cleaning tank limits the range and complexity of the parts being processed. Chemical cleaning methods can easily lead to environmental pollution. Laser cleaning is an emerging surface cleaning technology that better meets the current needs for environmental protection and sustainable social development. Backpack-type laser cleaning machines combine compact size, easy operation, high-efficiency cleaning, non-contact operation, and pollution-free operation into one.

[0003] When using backpack-type laser cleaning equipment, it is usually carried manually. This can easily reduce the stability of the laser emitter head during laser cleaning of workpieces, causing deviations in the workpiece during cleaning. In addition, the backpack-type laser cleaning equipment cannot support the backpack, causing the weight of the backpack to be concentrated on the shoulders of the user, which can easily cause fatigue if the equipment is used for a long time. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a backpack-style laser cleaning device. The operator can observe the inside of a wrist-limiting ring, allowing the wrist to move freely within it. The operator can then lift the laser mount by gripping the handle. By sliding the adjusting hollow tube and the adjusting support rod, the support rod can be pulled out from the hollow tube to adjust its height. Once adjusted, a fixing rod is pushed to one side, extending through the hollow tube and into the adjusting support rod to secure it. This allows the lifting plate to support the operator's arm. The laser emitter then performs laser cleaning on the workpiece. During laser cleaning, a movable ball bearing adheres to the workpiece surface. The movement of the ball bearing against the support base allows it to roll according to the operator's arm movement, and the lifting plate further supports the operator's arm during cleaning. The device provides relatively stable cleaning. Before using the laser cleaning backpack, the movement of the first support adjustment column and connecting plate allows the movable support wheel to be moved under the backpack. Tightening the first threaded fastening bolt secures the first threaded fixing plate. The sliding of the first and second support adjustment columns allows the second column to be pulled downwards and extended from the inside of the first column, adjusting its length so the movable support wheel can contact the ground. Tightening the second threaded fastening bolt secures the second column. This design allows the first and second support adjustment columns to support the backpack when it is carried, while the movable support wheel rolls according to the worker's movement, reducing fatigue and solving the problems of poor stability and shoulder fatigue associated with carrying the backpack.
