Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a trimming device for producing acrylic plates. Background Art

[0002] Acrylic, also known as specially treated organic glass, is a replacement product for organic glass. Light boxes made of acrylic have the characteristics of good light transmission, pure color, rich color, beautiful and smooth, taking into account both day and night effects, long service life, and no impact on use. In order to meet market demand and product diversity, acrylic sheets need to be designed in shape and size during production and manufacturing, and then the excess parts are cut off through a trimming device. Traditional trimming devices use knife cutting, laser cutting and other methods, while the latter laser cutting is a new cutting method. A high-power density laser beam is used to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves over the material, the holes continuously form a very narrow slit to complete the cutting of the material. In the existing laser cutting process, burrs and rough edges are often generated after cutting due to temperature and material reasons, which require manual removal and polishing by later staff, which is cumbersome.
