The number of the support seat 4, the rotating shaft 401, the swinging seat 402, the rotating rod 403 and the roller 404 is two, and they are symmetrically arranged on the left and right sides of the welding mechanism 1 respectively. A first gear 405 is fixedly connected to the front of the rotating shaft 401. The number of the first gears 405 is two, and the two first gears 405 mesh with each other. A connecting frame 406 is fixedly connected to the left side of the welding mechanism 1. The shape of the connecting frame 406 is E-shaped. A second hydraulic chamber 407 is fixedly connected to the left side of the connecting frame 406. A second hydraulic rod 408 is slidably connected to the inner surface of the second hydraulic chamber 407. The second hydraulic rod 408 and the second hydraulic chamber 407 are slidably connected through a piston. The lower end of the second hydraulic rod 408 is fixedly connected to a first rack 409. The first rack 409 meshes with the left side of the first gear 405. The first rack 409 meshes with the first gear 405 located on the left side. A spring component 5 for driving the roller 404 to rotate is assembled behind the welding mechanism 1. A cleaning component 6 for blowing and cleaning the electrode is assembled behind the spring component 5. A first hydraulic chamber 410 is fixedly connected to the left side of the welding mechanism 1. There is a liquid in the first hydraulic chamber 410. The first hydraulic chamber 410 and the second hydraulic chamber 407 are connected by a pipeline 412.

[0026] When the above-mentioned device is used, the welding rod is first placed under the welding mechanism 1, so that the welding rod is aligned with the socket under the welding mechanism 1, and then the electric push rod 2 is started to extend it. The extension of the electric push rod 2 pushes the insertion seat 3 to move to the left, so that the insertion seat 3 opens the cavity inside the welding mechanism 1 to facilitate the insertion of the welding rod. When the insertion seat 3 moves to the left, the first hydraulic rod 411 is also pulled to move to the left. When the first hydraulic rod 411 moves to the left, it extends into the first hydraulic chamber 410, thereby pushing the liquid in the first hydraulic chamber 410 to be injected into the second hydraulic chamber 407 through the pipe 412, and then pushing the second hydraulic rod 408 to extend downward from the second hydraulic chamber 407. The descent of the second hydraulic rod 408 drives the first hydraulic chamber 410 to move to the left. The rack 409 slides downward on the limit bar 413. The downward sliding of the first rack 409 will drive the first gear 405 on the left to rotate counterclockwise. The counterclockwise rotation of the first gear 405 on the left will drive the rotating shaft 401 to rotate counterclockwise. The swing seat 402 is flipped downward by the counterclockwise rotation of the rotating shaft 401, thereby driving the rotating rod 403 to move the roller 404 to the bottom of the welding mechanism 1. At the same time, the counterclockwise rotation of the first gear 405 on the left will drive another gear to rotate clockwise, thereby driving the rotating shaft 401 to make the other swing seat 402 flip downward, so that the rollers 404 on the two swing seats 402 clamp the welding rod, thereby facilitating the guidance of the welding rod when it is inserted into the welding mechanism 1.

[0027] Example 2: See Figures 4-8The clockwork assembly 5 includes a receiving groove 501. The receiving groove 501 is in the shape of a culture dish, with its opening facing the rear.

The connecting plate 502 is fixedly connected to the rear of the welding mechanism 1. A rotating column 503 is passed through the front of the receiving groove 501 and is rotatably connected. A bearing is provided between the rotating column 503 and the receiving groove 501. The rotating column 503 is rotatably connected to the rear end of the rotating shaft 401. The rotating column 503 is rotatably connected to the rear end of the rotating shaft 401 located on the left side. There is an elastic force between the rotating column 503 and the inner surface of the receiving groove 501. The spiral spring 504 is connected to the inner wall of the receiving groove 501 at one end, and the other end is connected to the outer wall of the rotating column 503. The outer surface of the rotating column 503 is fixedly connected to a rotating seat 505. The rotating seat 505 is in the shape of a culture dish. The inner surface of the rotating seat 505 is fixedly connected to a tooth 506. The tooth 506 is in the shape of a triangle. A spring telescopic rod 507 is fixedly connected to the top of the rotating shaft 401. The cross-section of the spring telescopic rod 507 is square. The upper end of the spring telescopic rod 507 is fixedly connected to a toggle block 508. The cross-section of the toggle block 508 is triangular. The spring telescopic rod 507 is fixedly connected to the upper end of the spring telescopic rod 507. The left side of the rod 507 is fixedly connected to a top block 509, and the top block 509 is provided with an inclined surface. The rear of the welding mechanism 1 is fixedly connected to a top seat 510, and the top seat 510 is L-shaped. The clockwork assembly 5 also includes a rotating rod 511, which is rotatably connected to the rear of the swing seat 402. The rotating rod 511 is arranged behind the swing seat 402 on the left side. The outer surface of the rotating rod 511 is fixedly connected to a second gear 512, and a third gear 513 is engaged above the second gear 512. The third gear 513 is fixedly connected to the outer surface of the rotating rod 403, and the third gear 513 is arranged on the left side. On the rotating rod 403, a chain 514 is connected to the outer surface of the rotating seat 505, and a sprocket for the chain 514 to transmit the transmission is provided on the rotating rod 511 and the rotating seat 505, wherein the sprocket located on the rotating seat 505 is annular, and a damping ring 7 is provided on the outer surface of the rotating column 503, and a rubber bump 8 is fixedly connected to the inner surface of the damping ring 7.

[0028] When the above device is used, when the counterclockwise rotation of the first gear 405 on the left drives the rotating shaft 401 to rotate counterclockwise, the counterclockwise rotation of the rotating shaft 401 drives the spring telescopic rod 507 to make the toggle block 508 rotate counterclockwise around the rotating shaft 401, and the counterclockwise rotation of the toggle block 508 drives the teeth 506 in the rotating seat 505 to make the rotating seat 505 rotate counterclockwise, and the counterclockwise rotation of the rotating seat 505 drives the rotating column 503 to rotate counterclockwise. The counterclockwise rotation of the rotating column 503 will tighten the volute spring 504 in the receiving groove 501, thereby storing force in the volute spring 504. When the rotating shaft 401 rotates counterclockwise, the swing seat 402 will flip downward, and then the rotating rod 403 will be driven to move the roller 404 to the bottom of the welding mechanism 1 so that the two rollers 404 clamp the welding rod. The counterclockwise rotation of the rotating shaft 401 will drive the spring telescopic rod 507 and the toggle block 508 to move downward. At this time, the push block 509 on the spring telescopic rod 507 The top seat 510 will push the spring telescopic rod 507 to shrink, and the shrinkage of the spring telescopic rod 507 will pull the toggle block 508 to disengage it from the teeth 506 in the rotating seat 505. At this time, the teeth 506 in the rotating seat 505 lose their support, and the spiral spring 504 will release the torsion force to make the rotating column 503 rotate clockwise. The rotating column 503 will rotate slowly under the action of the rubber protrusion 8 in the damping ring 7, and the clockwise rotation of the rotating column 503 will drive the rotating seat 505 to rotate clockwise. The clockwise rotation of the rotating seat 505 drives the chain 514 to rotate the rotating rod 511 clockwise, and the clockwise rotation of the rotating rod 511 drives the second gear 512 to rotate clockwise. The clockwise rotation of the second gear 512 drives the third gear 513 to rotate counterclockwise. The counterclockwise rotation of the third gear 513 drives the rotating rod 403 to rotate the roller 404 on the left counterclockwise, thereby cooperating with the other roller 404 to transport the clamped welding rod upward into the welding mechanism 1.

[0029] Example 3: See Figures 5-8, the cleaning component 6 includes a support plate 601, the support plate 601 is fixedly connected to the rear of the accommodation groove 501, a limiting telescopic rod 602 is fixedly connected above the support plate 601, the number of the limiting telescopic rods 602 is two, the upper ends of the limiting telescopic rods 602 are fixedly connected with a lifting plate 603, the shape of the lifting plate 603 is convex, and two tension springs 604 are elastically connected between the lifting plate 603 and the support plate 601. The upper ends of the tension springs 604 are connected to the lower side of the lifting plate 603, and the lower ends are connected to the upper side of the support plate 601. The tension springs 604 will apply a pulling force to pull the lifting plate 603 downward in the normal state. An elastic airbag 605 is fixedly connected between the lifting plate 603 and the support plate 601. A jet pipe 606 is fixedly connected to the lower side of the support plate 601. The jet pipe 606 is aligned with the electrode insertion position below the welding mechanism 1. The jet pipe 606 is communicated with the inner surface of the elastic airbag 605. A through hole is provided in the support plate 601 for communication between the jet pipe 606 and the elastic airbag 605. The cleaning component 6 further includes a fourth gear 607. The fourth gear 607 is arranged behind the damping ring 7. The fourth gear 607 is fixedly connected to the outer surface of the rotating column 503. A second rack 608 is meshed with the right side of the fourth gear 607. The second rack 608 is fixedly connected to the left side of the lifting plate 603.

[0030] When the above-mentioned device is in specific use, when the rotating column 503 rotates counterclockwise, it will drive the fourth gear 607 to rotate counterclockwise. By the counterclockwise rotation of the fourth gear 607, the second rack 608 will be pushed up. By the rising of the second rack 608, the lifting plate 603 will be driven to rise, making it away from the support plate 601. At the same time, the tension spring 604 will be stretched, and the limiting telescopic rod 602 will extend. By the lifting plate 603 moving away from the support plate 601, the elastic airbag 605 will be stretched to inhale gas. When the torsion spring 504 releases torque and the rotating column 503 rotates clockwise, the clockwise rotation of the rotating column 503 will drive the fourth gear 607 to rotate clockwise to push the second rack 608 downward, and then drive the lifting plate 603 to move towards the support plate 601 with the assistance of the tension spring 604, thereby squeezing the elastic airbag 605. The gas in the elastic airbag 605 will be blown towards the electrode below the welding mechanism 1 through the jet pipe 606, so as to blow off the dust on the electrode when installing the electrode and keep the electrode clean.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
