Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a laser automatic repair welding device, comprising a base 4, an X-axis guide rail 5 is fixedly connected to the rear side of the top of the base 4, a first bracket 6 is arranged at the top of the X-axis guide rail 5, a Z-axis guide rail 7 is arranged at the front side of the first bracket 6, a second bracket 8 is fixedly connected to the front side of the Z-axis guide rail 7, a laser collimator 10 is arranged at the front side of the second bracket 8, a camera module 12 is arranged on the left side of the laser collimator 10, positioning blocks 3 are fixedly connected to the left and right sides of the top of the base 4, a workpiece 14 is arranged on the top of the base 4; a weld bead 15 is opened in the middle of the top of the base 4;

[0029] Specifically, the positioning block 3 is used to firmly fix the workpiece 14 on the top of the base 4. Subsequently, the camera module 12 is activated to take photos of the weld of the workpiece 14 for comparison. If the photographed result does not match the system standard part, the system will start the X-axis guide 5 and the Z-axis guide 7 to move the laser collimator 10, and start the laser collimator 10 to perform repair welding on the defective position. In this way, the system can compare the welding part with the standard part and automatically perform the repair welding operation.

[0030] Reference Figure 1 , an optical fiber 9 is arranged on the top of the laser collimator 10; a laser lens 11 is fixedly connected to the front side of the Z-axis guide rail 7; a transmission line 2 is arranged on the top of the first bracket 6, and the other end of the transmission line 2 is connected to the industrial computer 1;

[0033] Specifically, through the guidance of the laser 13, timely adjustments can be made when the workpiece 14 is offset during the repair welding process. The multiple areas 17 can assist in fixing the workpiece 14 and observing its repair welding position. The pores 16 are the defects required for welding. After taking pictures for comparison, the device can automatically move to repair the welding position.

[0034] Working principle: Before using the device, first fix the workpiece 14 on the top of the base 4 through the positioning block 3, then start the camera module 12 to take pictures and compare the weld of the workpiece 14. If the comparison result is inconsistent with the system standard parts, the system will start the X-axis guide 5 and the Z-axis guide 7 to move the laser collimator 10, and start the laser collimator 10 to perform repair welding on the defective position. In this way, the welding part can be compared with the standard parts and the automatic repair welding operation can be realized, thereby improving the practicality of the device.
