[0002] Laser welding technology has been widely used in industrial manufacturing. Its precision and efficiency make it the preferred method for joining metals, plastics and other materials. In the laser welding process, the laser galvanometer plays a vital role. It is responsible for guiding the laser beam to the welding position quickly and accurately. Therefore, the design and optimization of the clamping and adjustment device of the laser galvanometer becomes particularly important.

Drive the sliding rod and the laser galvanometer clamping block to move to both sides, and the staff can catch the laser galvanometer body under the laser galvanometer body. However, the laser galvanometer clamping and adjusting device of the existing laser welder still has many shortcomings in actual use. For example, the angle of the galvanometer cannot be deflected during use, so the route of the laser will not be changed, and the laser cannot be used to achieve multi-angle welding of the object. The position of the processed object needs to be moved manually, which affects the welding efficiency. Adjusting the angle of the laser galvanometer can optimize the energy distribution of the laser, improve the energy utilization rate of the laser, and ensure that the laser is more effective during the processing process. Therefore, it is necessary to design a laser galvanometer clamping and adjusting device for a laser welder. Summary of the invention

The two connected pushing columns approach each other, and the pushing columns push the second clamping plate connected to the first clamping plate towards each other to achieve the clamping of the galvanometer.

The left side of the front second clamping plate 302 is fixedly connected to an L-shaped support plate 304, and the bottom end of the L-shaped support plate 304 is slidably connected to a pull rod 305, and a sliding column 306 is provided at a right angle to the L-shaped support plate 304.

Rapid replacement of the laser galvanometer 5 can significantly reduce downtime. Since laser processing is usually an assembly line operation, the ability to quickly replace the galvanometer 5 means that production can be resumed as soon as possible, thereby improving overall production efficiency.

[0025] The cleaning mechanism 4 includes a cleaning bracket 401, which is fixedly connected to the upper surface of the frame 220. A compression rod 403 is fixedly connected to the right side of the cleaning bracket 401. The end of the compression rod 403 away from the cleaning bracket 401 is rotatably connected to a rotating rod 405. The outer surface of the rotating rod 405 is fixedly connected to a cleaning plate 402. Two cleaning springs 404 are arranged between the cleaning bracket 401 and the cleaning plate 402, and the two ends of each cleaning spring 404 are respectively fixedly connected to the cleaning bracket 401 and the cleaning plate 402.

The cleaned surface of the galvanometer 5 can improve the quality of the laser beam, ensure that the laser spot is more uniform, and can improve the processing effect and the surface quality of the final product.

[0026] Working principle: When in use, the entire device is fixedly installed on the laser welding machine, and the external motor is started to rotate the semi-threaded rod 205 clockwise. At this time, the guide plate 222 moves downward along the guide column 216 under the rotation of the semi-threaded rod 205. Under the action of the first hinge rod 208 and the second hinge rod 209, the two push plates 210 on the support frame 207 are moved closer to each other. Similarly, the two push columns 212 connected to the push plate 210 through the push block 211 can be moved closer to each other. The push column 212 pushes the second clamping plate 302 connected to the first clamping plate 301 to move closer to each other. At the same time, the connecting rod 217 is also extended, so as to achieve the clamping of the galvanometer 5.

[0027] When the semi-threaded rod 205 rotates, the crown gear 204 meshing with the flat gear 206 drives the driving wheel 203 on the screw rod 201 to rotate. At this time, the driven wheel 221 connected by the transmission belt moves synchronously. The rotation of the driven wheel 221 drives the rotating drum 218 on the connecting rod 217 to rotate. The above process can clamp the galvanometer 5 and adjust the angle of the galvanometer 5. Adjusting the angle of the laser galvanometer 5 can change the route of the laser, so that the laser can achieve multi-angle welding of the object without repeatedly moving the position of the processed object, thereby improving the welding efficiency. In addition, adjusting the angle of the galvanometer can optimize the energy distribution of the laser, improve the energy utilization rate of the laser, and ensure that the laser is more effective in the processing process, which is conducive to reducing energy consumption and improving environmental protection.

[0028] When the galvanometer 5 needs to be replaced, the pull rod 305 can be pulled outward to disengage the pull rod 305 from the first clamping plate 301, and the L-shaped support plate 304 can be pushed forward at the same time, so that the sliding column 306 on the L-shaped support plate 304 moves in the displacement groove while pulling the second clamping plate 302. The second clamping plate 302 squeezes the telescopic column 303 and increases the gap between the two second clamping plates 302. The galvanometer 5 will fall downward under the action of gravity, and then the galvanometer 5 can be caught by hand. This process can quickly replace the galvanometer 5. Rapid replacement of the laser galvanometer 5 can significantly reduce downtime. Since laser processing is usually an assembly line operation, being able to quickly replace the galvanometer 5 means that production can be resumed as soon as possible, thereby improving overall production efficiency.

[0029] When the galvanometer 5 rotates, it will press the cleaning plate 402, so that the cleaning plate 402 fits and rubs against the surface of the galvanometer 5. When the galvanometer 5 presses the cleaning plate 402, under the action of the rotating rod 405, the cleaning plate 402 and the surface of the galvanometer 5 will always be in the same horizontal plane. Under the joint action of the compression rod 403 and the cleaning spring 404, the cleaning cotton on the cleaning plate 402 will always be in close contact with the surface of the galvanometer 5. The cleaning cotton and the surface of the galvanometer 5 will be in close contact and friction to remove dust and dirt attached to the surface of the galvanometer 5. Cleaning the galvanometer 5 can ensure that the light beam maintains the correct direction and improves the processing accuracy. The clean surface of the galvanometer 5 can improve the quality of the laser beam, ensure that the laser spot is more uniform, and can improve the processing effect and the surface quality of the final product.
