Description

Technical Field

[0001] The utility model relates to the technical field of engraving, and particularly relates to a support frame for laser engraving and an automatic engraving machine. Background Art

[0002] Engraving, in terms of processing principle, is a combined drilling and milling process, and various data input modes of the engraving machine can be handled with ease according to requirements. Computer engraving machines are divided into two categories: laser engraving machines and mechanical engraving machines. Among them, a laser engraving machine is an advanced device that uses a laser to engrave the material to be engraved.

[0003] A laser engraving machine is different from a mechanical engraving machine and other traditional manual engraving methods. A mechanical engraving machine uses mechanical means, such as materials with extremely high hardness like diamond, to engrave other things. While a laser engraving machine uses the thermal energy of the laser to engrave the material, and the laser in the laser engraving machine is the core. Generally speaking, the application range of a laser engraving machine is wider, the engraving accuracy is higher, and the engraving speed is faster, which can improve the engraving efficiency. Moreover, compared with the traditional manual engraving method, laser engraving can also make the engraving effect very delicate, make the surface of the engraved part smooth and round, quickly reduce the temperature of the non-metallic material to be engraved, and reduce the deformation and internal stress of the engraved object. It is no less than the craftsmanship level of manual engraving. Because of the many advantages of the laser engraving machine, the application of the laser engraving machine has gradually replaced the traditional engraving equipment and methods and become the main engraving equipment.

[0004] A laser engraving machine generally places the plate to be engraved on the single surface of the engraving table and engraves by controlling the engraving mechanism or device. Existing engraving machines generally engrave plates to be engraved with the same size. However, in actual applications, the sizes of the plates to be engraved vary, and during the engraving process of the plate to be engraved, it is necessary to firmly hold the plate to be engraved and keep it stable to ensure the engraving quality, effect, and efficiency.
