Description

Technical Field

[0001] The utility model relates to the technical field of laser marking machines, in particular to an automatic laser marking machine. Background Art

[0002] Laser marking machine uses laser beam to mark the surface of various materials permanently. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve out exquisite patterns, trademarks and words. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines and YAG laser marking machines. Laser marking machines are mainly used in some occasions that require more sophisticated and higher precision. They are used in electronic components, integrated circuits, electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, glasses and clocks, jewelry, auto parts, plastic buttons, building materials, and PVC pipes.

[0003] The automatic laser marking machines in the prior art are mainly divided into laser marking machines with conveyor belts and laser marking machines without conveyor belts. In order to increase the marking efficiency, laser marking machines with conveyor belts are usually used for marking operations.

[0004] At present, in the laser marking machine with a conveyor belt, the conveyor belt is set on one side of the laser marking machine, so that the marker of the laser marking machine is located above the conveyor belt, which is convenient for laser marking operations on the objects on the conveyor belt. However, in actual use, in order to prevent the position of the objects from shifting during transportation and affecting the marking effect, a limiting structure is usually set on the conveyor belt to enable the objects to move better to the bottom of the marker. The object limiting structures in the prior art are usually installed on both sides of the conveyor belt. When adjusting the spacing of the limiting structures, it is usually necessary to adjust the limiting structure on one side first, and then adjust the limiting structure on the other side. The operation is relatively cumbersome. At the same time, the laser marking machine does not have a good rotating structure when marking objects. If it is necessary to mark multiple angles of the objects, the operation is relatively inconvenient.

[0005] In view of this, the present technical solution proposes an automatic laser marking machine to better solve the above-mentioned problems. Utility Model Content
