The printing component 4 is installed at one end of the upper part of the printing workbench 1. A printing base plate 5 is provided at the bottom of the printing component 4. After a laser film is placed on the printing base plate 5, printing is performed through the printing component 4. One side of the printing base plate 5 is connected to a pick-and-place mechanism 6 installed at the other end of the upper part of the printing workbench 1. The printing base plate 5 can be pulled out from the bottom of the printing component 4 through the pick-and-place mechanism 6, and turned to one side to facilitate the pick-and-place of the laser film, and then the printing base plate 5 is extended into the bottom of the printing component 4 for printing.

The first frame plate 41 and the second frame plate 42 are symmetrically installed on both sides of one end of the printing workbench 1, and a raw material attachment block 43 is installed between the first frame plate 41 and the second frame plate 42. The two ends of the raw material attachment block 43 are connected and fixed to the first frame plate 41 and the second frame plate 42, and the bottom is supported by the bottom support plate 401 to ensure the stable installation of the raw material attachment block 43. It should be noted that the raw material attachment block 43 can be a material such as sponge that can absorb printing materials.
