Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and specifically to a quick-assembly laser engraving device. Background Technology

[0002] Laser engraving machines are high-tech products with a high level of integration of optics, mechanics, and electronics. In the mid-to-late 1990s, with the successful development of laser engraving technology, the engraving industry began to develop rapidly.

[0003] Laser engraving machines use a laser to generate laser light, which is then evenly and delicately irradiated onto the surface of materials such as fabric and leather. The intense light vaporizes the material at high temperatures, creating the base color or carving out arbitrary shapes. The light is transmitted through a emitting mirror and focused onto the material, causing it to rapidly melt and vaporize at high temperatures. Moving the laser head achieves the cutting effect. Compared to traditional hand engraving methods, laser engraving can achieve very fine engraving results, rivaling the level of craftsmanship of hand engraving, and is used in many industries.

[0004] Most laser engraving machines on the market currently adopt an integrated design. For example, utility model patent application CN218555941U discloses an integrated laser engraving machine, which includes: a laser engraving machine body, a worktable on the top of the laser engraving machine body, a laser head mounted on the top surface of the worktable, a laser tube located at the rear of the top surface of the worktable, a waste material recycling device located below the hopper, a water tank fixedly installed on one side of the bottom inner wall of the laser engraving machine body, a water pump fixedly installed on the bottom inner wall of the laser engraving machine body, and a compressed air pump fixedly installed on the other side of the bottom inner wall of the laser engraving machine body. This device adopts a structure with an internal water tank, water pump, and compressed air pump, which greatly reduces the footprint of the device during use.

[0005] However, due to its inherent design features, this existing integrated automated laser engraving machine has the following shortcomings:

[0006] In this technical solution, the water tank, water pump, compressed air pump, and other structures are all located inside the main body of the laser engraving machine. As a result, the number of parts inside the main body of the laser engraving machine increases, making disassembly more cumbersome and unable to meet the requirements of quick assembly and disassembly. Moreover, the overall weight of the main body of the laser engraving machine is greatly increased, causing trouble for operators in handling and disassembly. In addition, even after the water tank, compressed air pump, and water pump are removed from the main body of the laser engraving machine, they are still large in size, making transportation inconvenient and detrimental to transportation management.
