Compared with the existing galvanometer system, the double-headed laser galvanometer system of the present invention adds a group of XY galvanometer modules and corresponding Z-axis dynamic modules to realize the simultaneous operation of two XY galvanometer modules; the overall design of the double-headed laser galvanometer system is integrated and modular, and the marking or welding efficiency is doubled; a water-cooling design is adopted to improve the stability of the system.

[0004] However, the two XY galvanometer modules on the Z-axis dynamic box of a dual-head laser galvanometer system involved in the patent are not easy to replace, so a method is designed to replace any damaged XY galvanometer separately, while the undamaged XY galvanometer module is still installed on the Z-axis dynamic box. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcoming in the prior art that the XY galvanometer module is not easy to replace, and to propose a double-head laser galvanometer system.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] Preferably, a plurality of hemispherical grooves are provided on the top of the Z-axis dynamic box, and the hemispherical grooves are matched with the protrusions.

[0009] Preferably, one end of a first spring is fixedly connected to the inner walls of the two grooves on a side away from each other, and the other end of the first spring is fixedly connected to the second cross bar.

[0013] In the present invention, the double-headed laser galvanometer system drives the worm to rotate by rotating the T-shaped rod forward and backward, so that the worm wheel on the vertical rod rotates together with the worm. At this time, the second gear on the vertical rod cooperates with the two first gears in the U-shaped small hole to drive the chain to move, and then the chain will pull one of the limit rods. When the limit rod moves to the appropriate position, the second cross bar will slide into the groove under the pull of the first spring until it is no longer in contact with the disc. At this time, any damaged XY galvanometer module can be disassembled and replaced;

The two XY galvanometer modules can be disassembled in turn by rotating the T-bar in different directions, so that only the damaged XY galvanometer module is disassembled and replaced, while the other intact XY galvanometer module is still installed on the Z-axis dynamic box.
