Description

Technical Field

[0001] The present invention relates to the technical field of hockey stick cleaning, and in particular to a high-efficiency cleaning device for the surface of a hockey stick. Background Art

[0002] During the production of a hockey stick, the skeleton is first formed through molding. The surface is then coated with resin for reinforcement and strength. The surface is then roughened and painted for a smoother finish. Finally, a pattern is printed on the surface using water transfer technology. The hockey stick should be smooth overall, without any other forms of roughness or protrusions. However, during manufacturing, the surface roughness may be adjusted through specific processes to meet usage requirements, such as increasing friction and improving ball control. If the surface of the stick becomes sticky or astringent, it can be treated through grinding and polishing to improve its surface smoothness. Currently, the surface roughening process is generally performed manually. Some companies have also tried using automated equipment, but due to the severe surface scratches after automated grinding, it has not been widely adopted. Due to the high hardness of resin, manual grinding is labor-intensive and inefficient. It is difficult to ensure consistency over time, and the dust generated during grinding is harmful to the operator's health.

[0003] Therefore, there is an urgent need for an efficient cleaning device that uses laser cleaning technology to improve efficiency and reduce manual involvement. Summary of the Invention
