[0015] The slag removal device 18 includes a fixed block 181, which is fixedly connected to the top of the lifting plate 10. The inner wall of the fixed block 181 is rotatably connected to a rotating rod 182 through a torsion spring. The circumferential surface of the rotating rod 182 is fixedly connected to a straight plate 183. The side of the straight plate 183 away from the fixed block 181 is fixedly connected to a rotating rod 2 184. The circumferential surface of the rotating rod 2 184 is fixedly connected to a slag pushing plate 185. During the welding process, the lifting plate 10 moves upward to drive the fixed block 181 to move upward, and the fixed block 181 moves upward to drive the rotating rod 182 to move upward.

When the roller 188 passes over the protrusion 1810, the elastic retractable plate 187 will reset and retract, and drive the roller 188 to move upward, thereby generating vibration on the conduction plate 189, and transmitting the vibration to the welding table 3 so that the welding slag attached thereto can loosen and fall off, thereby reducing the labor intensity of the workers and improving the work efficiency of the workers.

[0016] Working principle: when starting to weld the hinge, place the hinge in the welding area. After the placement is completed, the motor 5 is started, and the motor 5 starts to drive the screw rod 6 to rotate. The rotation of the screw rod 6 will contact the thread on the surface of the screw rod 6 through the slider arranged inside the sliding plate 7, so that the sliding plate 7 can move left and right. The movement of the sliding plate 7 drives the inclined plate 8 to move. During the movement of the inclined plate 8, it will contact the inclined surface of the surface of the triangular plate 20, so that an upward squeezing force can be generated on the triangular plate 20, so that the triangular plate 20 moves upward. The upward movement of the triangular plate 20 drives the lifting plate 10 to move, and then the hinge on the lifting plate 10 can be driven to move together, so that the hinge contacts the pressure plate 12, so that the hinge can be fixed, so that the hinge will not shake or shift during welding, thereby improving the quality and aesthetics of the weld. The lifting plate 10 moves upward and drives the fixing rod 14 to move upward. The movement of the fixing rod 14 drives the push plate 15 to move upward. The movement of the push plate 15 drives the U-shaped plate 2 16 to move upward. The movement of the U-shaped plate 2 16 drives the inclined plate 2 17 to move upward. In the process of the inclined plate 2 17 moving upward, the inclined plate 2 17 will contact with the inclined strip plate 13, so that the inclined strip plate 13 produces an extrusion force to move backward on the inclined plate 2 17 through the inclined surface, forcing the inclined plate 2 17 to move backward. The backward movement of the inclined plate 2 17 drives the U-shaped plate 2 16 to move backward. The backward movement of the U-shaped plate 2 16 drives the push plate 15 to move backward and drives the spring to stretch, so that the hinge can be adjusted before the hinge is fixed, and the hinge placed on the lifting plate 10 is pushed toward the middle, thereby avoiding the offset of the hinge position, so that the accuracy of the hinge welding can be improved.

[0017] During the welding process, the lifting plate 10 moves upward to drive the fixed block 181 to move upward, the fixed block 181 moves upward to drive the rotating rod 182 to move upward, the rotating rod 182 moves upward to drive the straight plate 183 to move upward, and the straight plate 183 rotates counterclockwise through the torsion spring during the upward movement, the straight plate 183 rotates to drive the rotating rod 2 184 to rotate, and the rotating rod 2 184 rotates to drive the slag pushing plate 185 to move, so that the welding slag generated during the welding process can be cleaned to avoid excessive accumulation of welding slag, which requires workers to clean it manually, making the work more cumbersome. At the same time, the sliding plate 7 moves to drive the U-shaped frame 186 to move, and the U-shaped frame 186 moves to drive the elastic telescopic plate 187 to move. The movement of the retractable plate 187 drives the roller 188 to move. The movement of the roller 188 will contact the conductive plate 189 and generate friction to make the roller 188 rotate. During the movement of the roller 188, it will contact the protrusion 1810 and generate an extrusion force on the roller 188 to make the roller 188 move downward. The downward movement of the roller 188 will stretch the elastic retractable plate 187. When the roller 188 passes over the protrusion 1810, the elastic retractable plate 187 will reset and retract, and drive the roller 188 to move upward, thereby generating vibration on the conductive plate 189, and transmitting the vibration to the welding table 3 so that the welding slag attached thereto can loosen and fall off, thereby reducing the labor intensity of the workers and improving the work efficiency of the workers.

[0018] See also Figure 1-Figure 8On the basis of the above embodiment, in another embodiment of the present invention, the anti-stuck device 19 includes a collection box 191, which is slidably connected to the inner wall of the workbench 1, and the inner wall of the collection box 191 is rotatably connected to a rotating plate 192 through a torsion spring, and the rear part of the U-shaped frame 186 is fixedly connected to an H-shaped frame 193, and the bottom of the H-shaped frame 193 is fixedly connected to a connecting plate 194, and the inner wall of the connecting plate 194 is fixedly connected to a push plate 195. In the process of cleaning the welding slag, the movement of the U-shaped frame 186 drives the H-shaped frame 193 to move, and the movement of the H-shaped frame 193 drives the connecting plate 194 to move, and the movement of the connecting plate 194 drives the push plate 195 to move, so that the welding slag dropped into the collection box 191 can be pushed and dispersed, so as to avoid the accumulation of welding slag in the same place of the collection box 191, resulting in a waste of space inside the collection box 191. If the welding slag accumulates too high in the same place, it will cause the welding slag to contact with the running parts of the device, which is very likely to cause problems such as device jamming, thereby affecting normal welding. When the welding slag in the collection box 191 is poured out, the movement of the collection box 191 drives the rotating plate 192 to move, and the movement of the rotating plate 192 will contact the rear part of the push plate 195, thereby generating an extrusion force on the push plate 195 to make the rotating plate 192 rotate. Only then can the collection box 191 be normally drawn out, and the front part of the connecting plate 194 is fixedly connected to the connecting block 196, and the front part of the connecting block 196 is fixedly connected to the slag removal ring 197. The surface of the collection box 191 and the inner wall of the push plate 195 are mutually The front part of the rotating plate 192 contacts with the rear part of the pushing plate 195, and the circumferential surface of the screw rod 6 contacts with the inner wall of the slag removing ring 197. At the same time, the movement of the connecting plate 194 drives the connecting block 196 to move, and the movement of the connecting block 196 drives the slag removing ring 197 to move, so that the welding slag dropped on the surface of the screw rod 6 can be scraped off to avoid excessive accumulation of welding slag on the surface of the screw rod 6, which affects the normal operation of the device and causes the welding to fail to proceed normally, which will waste time and resources and cause unnecessary losses.

[0019] Working principle: In the process of cleaning welding slag, the movement of U-shaped frame 186 drives the movement of H-shaped frame 193, the movement of H-shaped frame 193 drives the movement of connecting plate 194, and the movement of connecting plate 194 drives the movement of push plate 195, so that the welding slag dropped into the collection box 191 can be pushed and scattered to avoid the accumulation of welding slag in the same place of collection box 191, resulting in waste of space inside collection box 191. If welding slag accumulates too high in the same place, it will cause the welding slag to contact with the running parts of the device, which is very likely to cause problems such as device jamming, thereby affecting normal welding. When pouring out the welding slag in the collection box 191 The movement of the collecting box 191 drives the rotating plate 192 to move. The movement of the rotating plate 192 will contact the rear part of the pushing plate 195, thereby generating an extruding force on the pushing plate 195 to cause the rotating plate 192 to rotate. Only then can the collecting box 191 be pulled out normally. At the same time, the movement of the connecting plate 194 drives the connecting block 196 to move. The movement of the connecting block 196 drives the slag removing ring 197 to move, so that the welding slag dropped on the surface of the screw rod 6 can be scraped off, avoiding excessive accumulation of welding slag on the surface of the screw rod 6 to affect the normal operation of the device, and then causing the welding to fail to proceed normally, which will waste time and resources and cause unnecessary losses.
