[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, please refer to Figures 1 - 5 , A welding device for the rear cover of a new energy vehicle, including a welding chamber 100. A first power rod 200 driven by an electric push rod is assembled at the top of the welding chamber 100. A welding head 300 is assembled at the bottom of the first power rod 200. A second power rod 800 driven by an electric push rod is assembled on the side of the welding chamber 100. An elastic splint 400 is assembled on the side of the second power rod 800. Place the rear cover in the welding chamber 100, start the second power rod 800 driven by the electric push rod to move sideways. The two second power rods 800 move towards each other, driving the elastic splints 400 assembled on the second power rods 800 to move, and initially clamping the rear cover. Subsequently, start the first power rod 200 driven by the electric push rod, driving the welding head 300 assembled at the bottom of the first power rod 200 to move downward to perform corresponding welding operations; A pressure bar 501 is fixedly connected to the side of the first power rod 200, and a hydraulic device 502 is fixedly assembled on the side of the welding bin 100. One end of the hydraulic device 502 is slidably connected to a force-bearing rod 503, and the other end of the hydraulic device 502 is slidably connected to a push rod 504. A first spring 505 is assembled at the bottom of the force-bearing rod 503. When performing corresponding welding operations, the downward-moving first power rod 200 drives the pressure bar 501 fixedly connected thereto to move downward. During the downward movement of the pressure bar 501, it can squeeze the force-bearing rod 503 and cause the force-bearing rod 503 to move downward. In cooperation with the hydraulic device 502 slidably connected to the force-bearing rod 503, the pressure inside the hydraulic device 502 is increased, driving the push rod 504 slidably connected to the hydraulic device 502 to move sideways.

[0019] An elastic clamping plate 400 is connected to a force-bearing plate 507 through an elastic telescopic block 506 on the side. A connecting rod 508 is fixedly connected to the side of the force-bearing plate 507. A rotating block 509 is rotatably connected to the side of the force-bearing plate 507. The rotating block 509 is located on the side of the connecting rod 508 and is in an articulated state with the connecting rod 508. A through air pressure chamber 510 is fixedly connected inside the force-bearing plate 507. A suction cup 511 is assembled at one end of the air pressure chamber 510. A sliding rod 512 is slidably connected to the other end of the air pressure chamber 510. The sliding rod 512 is located on the side of the rotating block 509 and is in an articulated state with the rotating block 509. When the push rod 504 moves sideways, it causes the push rod 504 to squeeze the force-bearing plate 507, and through the elastic telescopic block 506, an additional force is applied to the elastic clamping plate 400 to further clamp the rear cover. And when the force-bearing plate 507 moves sideways, it can drive the connecting rod 508 fixedly connected to the force-bearing plate 507 to move toward the side close to the elastic clamping plate 400. Also, because the rotating block 509 hinged to the connecting rod 508 is restricted by the elastic clamping plate 400 rotatably connected to the rotating block 509, the rotating block 509 rotates, driving the sliding rod 512 hinged to the rotating block 509 to move away from the air pressure chamber 510. In cooperation with the air pressure chamber 510 slidably connected to the sliding rod 512, the residual gas between the suction cup 511 and the rear cover can be extracted into the air pressure chamber 510, improving the adsorption effect between the suction cup 511 and the rear cover. In this way, the device can be made more stable during welding, thereby improving the welding effect of the device.

[0020] After the welding operation is completed, the first power rod 200 drives the welding head 300 and the pressure bar 501 to reset, causing the force-bearing rod 503 to lose its restriction and move upward under the action of the first spring 505 to reset. Subsequently, the second power rod 800 is activated to drive the elastic clamping plate 400 to reset. To facilitate the next activation of the device.

[0021] The interior of the welding chamber 100 is equipped with a cleaning component 600 for cleaning welding slag, and the interior of the welding chamber 100 is equipped with a cooling component 700 for heat dissipation.

[0022] During use, place the rear cover inside the welding chamber 100, start the power rod two 800 driven by an electric push rod to move laterally, the power rods two 800 on both sides move towards each other, drive the elastic clamping plates 400 assembled on the power rod two 800 to move, and initially clamp the rear cover. Subsequently, start the power rod one 200 driven by an electric push rod, drive the welding head 300 assembled at the bottom of the power rod one 200 to move downward, and perform corresponding welding operations; at this time, the downward moving power rod one 200 drives the pressure rod 501 fixedly connected thereto to move downward. During the downward movement of the pressure rod 501, it can squeeze the force receiving rod 503 and cause the force receiving rod 503 to move downward. In cooperation with the hydraulic device 502 slidably connected to the force receiving rod 503, the pressure inside the hydraulic device 502 increases, drives the push rod 504 slidably connected to the hydraulic device 502 to move laterally, causes the push rod 504 to squeeze the force receiving plate 507, and applies an additional force to the elastic clamping plate 400 through the elastic telescopic block 506 to further clamp the rear cover; and when the force receiving plate 507 moves laterally, it can drive the connecting rod 508 fixedly connected to the force receiving plate 507 to move towards the side close to the elastic clamping plate 400. Also, because the rotating block 509 hinged to the connecting rod 508 is restricted by the elastic clamping plate 400 rotatably connected to the rotating block 509, the rotating block 509 rotates, drives the sliding rod 512 hinged to the rotating block 509 to move away from the air pressure chamber 510, and in cooperation with the air pressure chamber 510 slidably connected to the sliding rod 512, the residual gas between the suction cup 511 and the rear cover can be extracted into the air pressure chamber 510 through the air pressure chamber 510, improving the adsorption effect between the suction cup 511 and the rear cover; after the welding operation is completed, the power rod one 200 drives the welding head 300 and the pressure rod 501 to reset, causing the force receiving rod 503 to lose its restriction and move upward under the action of the first spring 505 to reset. Subsequently, enable the power rod two 800 again to drive the elastic clamping plate 400 to reset.

[0023] Example two, please refer to Figures 1 - 6, on the basis of the first embodiment, the cleaning component 600 includes a hydraulic chamber 601. A fixed seat 602 is assembled on the side of the welding chamber 100. A reciprocating lead screw 603 driven by a servo motor is rotatably connected inside the fixed seat 602. A sliding block 604 is connected to the outside of the reciprocating lead screw 603 by threading. The sliding block 604 is located inside the fixed seat 602 and is in a sliding connection state with the fixed seat 602. An elastic cleaning plate 605 is assembled on the side of the sliding block 604. After the corresponding welding operation is completed, the servo motor is started to drive the reciprocating lead screw 603 driven by the servo motor to rotate. Since the sliding block 604 assembled on the reciprocating lead screw 603 by threading is restricted by the fixed seat 602 that is slidably connected to the sliding block 604, the sliding block 604 can reciprocate horizontally. The sliding block 604 can drive the elastic cleaning plate 605 assembled on its side to reciprocate, and scrape the welding slag at the bottom of the inner wall of the welding chamber 100.

[0024] One end of the hydraulic chamber 601 is slidably connected to a transmission rod 606. The transmission rod 606 is located on the side of the force-receiving rod 503 and is in a fixed state with the force-receiving rod 503. The other end of the hydraulic chamber 601 is slidably connected to a pressing plate 607. The top of the elastic cleaning plate 605 is connected to a connecting plate 609 through an elastic telescopic rod 608. When the force-receiving rod 503 moves upward for reset, that is, when the welding operation is completed, it can drive the transmission rod 606 fixedly connected to it to move upward. Cooperating with the hydraulic chamber 601 slidably connected to the transmission rod 606, the pressure in the hydraulic chamber 601 increases, driving the pressing plate 607 slidably connected to the hydraulic chamber 601 to move downward. The pressing plate 607 then presses the connecting plate 609 and applies an additional force to the elastic cleaning plate 605 through the elastic telescopic rod 608. The cleaning effect of the elastic cleaning plate 605 on the welding slag is improved.

[0025] When the first power rod 200 moves downward to perform the welding operation again, the transmission rod 606 moves downward again, driving the pressing plate 607, thereby canceling the restriction on the elastic cleaning plate 605. Facilitating the next activation of the device.

[0026] During use, based on the first embodiment, after completing the corresponding welding operation, start the servo motor to drive the reciprocating lead screw 603 driven by the servo motor to rotate. Since the slider 604 assembled on the reciprocating lead screw 603 through threads is restricted by the fixed seat 602 slidably connected to the slider 604, the slider 604 can reciprocate horizontally. The slider 604 can drive the elastic cleaning plate 605 assembled on its side to reciprocate, scraping the welding slag at the bottom of the inner wall of the welding chamber 100. When the force rod 503 moves upward for reset, it can drive the transmission rod 606 fixedly connected thereto to move upward. In cooperation with the hydraulic chamber 601 slidably connected to the transmission rod 606, the pressure in the hydraulic chamber 601 increases, driving the pressing plate 607 slidably connected to the hydraulic chamber 601 to move downward. The pressing plate 607 then presses the connecting plate 609 and applies an additional force to the elastic cleaning plate 605 through the elastic telescopic rod 608. When the first power rod 200 moves downward to resume the welding operation, the transmission rod 606 moves downward again, driving the pressing plate 607, thereby canceling the restriction on the elastic cleaning plate 605.

[0027] Embodiment Three. Please refer to Figures 1 - 8 , based on the first and second embodiments, the cooling assembly 700 includes a fan power shaft 701. A first bevel gear 702 is drivingly connected to the side of the reciprocating lead screw 603. A connecting block 703 is rotatably connected to the side of the fixed seat 602. A second bevel gear 704 is fixedly connected to the side of the connecting block 703. The second bevel gear 704 is located on the side of the first bevel gear 702 and is in a meshing state with the first bevel gear 702. When the reciprocating lead screw 603 rotates rapidly, that is, when the welding operation is completed, the reciprocating lead screw 603 drives the first bevel gear 702 drivingly connected thereto to rotate, causing the first bevel gear 702 to drive the second bevel gear 704 meshing therewith to rotate. The second bevel gear 704 drives the connecting block 703 fixedly connected thereto to rotate.

[0028] A first sprocket 705 is fixedly connected to the outside of the connecting block 703. A chain 706 is assembled on the outside of the first sprocket 705. A second sprocket 707 is assembled on the outside of the fan power shaft 701. When the connecting block 703 rotates, it causes the first sprocket 705 fixedly connected thereto to rotate. In cooperation with the chain 706 assembled on the outside of the first sprocket 705, the second sprocket 707 drivingly connected to the first sprocket 705 through the chain 706 rotates. The second sprocket 707 then drives the fan power shaft 701 to rotate, thereby enabling the fan. In this way, the fan can be enabled after the welding operation is completed to perform corresponding rapid cooling operations on the rear cover that has just completed the welding operation, making the device easier to use.

[0029] In use, based on the first and second embodiments, when the reciprocating lead screw 603 rotates rapidly, i.e., when the welding operation is completed, the reciprocating lead screw 603 drives the first bevel gear 702 connected to it in transmission to rotate, causing the first bevel gear 702 to drive the second bevel gear 704 meshing with it to rotate. The second bevel gear 704 drives the connecting block 703 fixedly connected to it to rotate, causing the connecting block 703 to drive the first sprocket 705 fixedly connected to it to rotate. Cooperating with the chain 706 assembled outside the first sprocket 705, the second sprocket 707 connected to the first sprocket 705 in transmission through the chain 706 rotates. The second sprocket 707 then drives the fan power shaft 701 to rotate, thereby enabling the fan.
