[0021] When using the dual-galvanometer-based precision laser cutting device, Figure 1-Figure 4As shown, first, the whole device is placed and powered by an external power supply. When cutting the workpiece, the workpiece is placed on the support plate 3. The support function of the workpiece can be achieved through multiple groups of support plates 3. When cutting, the bottom plate 5 is driven to move by the transverse driving mechanism, which can drive the gantry 4 and the laser cutting head 13 to move forward and backward, thereby realizing the front and rear position adjustment. With the guiding effect of the guide wheel 401, the stability of the movement of the gantry 4 can be guaranteed. With the longitudinal driving mechanism, the movable frame 9 is driven to move, and the left and right position adjustment of the laser cutting head 13 can be realized to facilitate the cutting process. During the cutting process, when it is necessary to adjust the inclination angle of the laser cutting head 13, it is only necessary to control the four second electric telescopic rods 1101 to extend and retract. With the function of the first universal ball joint 1102 and the second universal ball joint 1201, the multi-directional adjustment function of the movable disk 12 and the laser cutting head 13 can be realized, so as to better meet the cutting requirements of different workpieces.

[0023] During the processing, Figure 1-Figure 4 As shown, when cutting, the cooling fan 1302 is started at the same time. The cooling fan 1302 can quickly dissipate the heat on the surface of the cut workpiece, thereby achieving rapid cooling of the workpiece and avoiding burns to workers due to excessive temperature, thereby ensuring the safety of the device. When the longitudinal mechanism drives the bottom plate 5 to move forward and backward, the vertical plate 6 is forced to move synchronously, and the spring 701 provides a force for the scraper 7, so that the scraper 7 generates pressure on the support plate 3.

In the cleaning process, the scraper 7 can be kept in a flexible state through the action of the connecting rod 8 to avoid damage to the scraper 7 and the support plate 3 due to contact and collision with foreign objects, thereby ensuring the service life of the device. This is the working principle of the precision laser cutting device based on dual galvanometers.
