[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1, please refer to Figures 1-5 A welding device for the rear cover of a new energy vehicle includes a welding chamber 100. A power rod 200 driven by an electric push rod is mounted on the top of the welding chamber 100. A welding head 300 is mounted on the bottom of the power rod 200. A second power rod 800 driven by an electric push rod is mounted on the side of the welding chamber 100. An elastic clamping plate 400 is mounted on the side of the second power rod 800. When the rear cover is placed inside the welding chamber 100, the second power rod 800 driven by the electric push rod is activated to move laterally. The two power rods 800 on either side move towards each other, causing the elastic clamping plate 400 mounted on the second power rod 800 to move, initially clamping the rear cover. Subsequently, the first power rod 200 driven by the electric push rod is activated, causing the welding head 300 mounted on the bottom of the first power rod 200 to move downwards for the corresponding welding operation.

[0031] A pressure rod 501 is fixedly connected to the side of the power rod 200, and a hydraulic device 502 is fixedly mounted on the side of the welding chamber 100. One end of the hydraulic device 502 is slidably connected to a force-bearing rod 503, and the other end is slidably connected to a push rod 504. A spring 505 is mounted at the bottom of the force-bearing rod 503. During the corresponding welding operation, the downward-moving power rod 200 drives the pressure rod 501 fixedly connected to it to move downward. During the downward movement of the pressure rod 501, it can squeeze the force-bearing rod 503 and cause the force-bearing rod 503 to move downward. In conjunction with the hydraulic device 502 slidably connected to the force-bearing rod 503, the pressure inside the hydraulic device 502 increases, causing the push rod 504 slidably connected to the hydraulic device 502 to move to the side.

[0032] The side of the elastic clamping plate 400 is connected to a force-bearing plate 507 via an elastic telescopic block 506. 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 elastic clamping plate 400. The rotating block 509 is located on the side of the connecting rod 508 and is hinged to the connecting rod 508. A through air pressure chamber 510 is fixedly connected inside the elastic clamping plate 400. A suction cup 511 is fitted 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 hinged to the rotating block 509. When the push rod 504 moves to the side, it presses against the force plate 507 and applies an additional force to the elastic clamping plate 400 via the elastic telescopic block 506, further clamping the back cover. Simultaneously, the force plate 507 moves to the side, causing the connecting rod 508, which is fixedly connected to the force plate 507, to move closer to the elastic clamping plate 400. Because the rotating block 509, hinged to the connecting rod 508, is restricted by the elastic clamping plate 400, which is rotatably connected to the rotating block 509, the rotating block 509 rotates. This causes the sliding rod 512, hinged to the rotating block 509, to move away from the pressure chamber 510. In conjunction with the pressure chamber 510, which is slidably connected to the sliding rod 512, residual gas between the suction cup 511 and the back cover is extracted into the pressure chamber 510, improving the adsorption effect between the suction cup 511 and the back cover. This makes the device more stable during welding, thereby improving the welding effect.

[0033] After the welding operation is completed, the power rod 200 drives the welding head 300 and the pressure rod 501 to reset, causing the force rod 503 to be unrestrained and move upward under the action of the spring 505 to reset. Then, the power rod 800 is activated again to drive the elastic clamp 400 to reset, so as to facilitate the next use of the device.

[0034] The welding chamber 100 is equipped with a cleaning component 600 for cleaning welding slag, and a cooling component 700 for heat dissipation.

[0035] In use, the back cover is placed in the welding chamber 100. The second power rod 800, driven by an electric push rod, is moved laterally. The two power rods 800 on either side move towards each other, causing the elastic clamping plate 400 mounted on the second power rod 800 to move, initially clamping the back cover. Then, the first power rod 200, driven by an electric push rod, is activated, causing the welding head 300 mounted at the bottom of the first power rod 200 to move downwards for welding operations. At this time, the downward-moving first power rod 200 causes the pressure rod 501, which is fixedly connected to it, to move downwards. During the downward movement, the pressure rod 501 compresses the force-bearing rod 503, causing it to move downwards. This, in conjunction with the hydraulic device 502 slidably connected to the force-bearing rod 503, increases the pressure within the hydraulic device 502, causing the push rod 504, slidably connected to the hydraulic device 502, to move laterally. This causes the push rod 504 to compress the force-bearing plate 507 and, through the elastic telescopic block 506, apply an additional force to the elastic clamping plate 400. The rear cover is clamped in one step; and as the force plate 507 moves to the side, it drives the connecting rod 508, which is fixedly connected to the force plate 507, to move closer to the elastic clamping plate 400. Because the rotating block 509, which is hinged to the connecting rod 508, is restricted by the elastic clamping plate 400, which is rotatably connected to the rotating block 509, the rotating block 509 rotates, causing the sliding rod 512, which is hinged to the rotating block 509, to move away from the air pressure chamber 510. This, in conjunction with the sliding rod... The air pressure chamber 510, which is slidably connected to 512, can draw the residual gas between the suction cup 511 and the back cover into the air pressure chamber 510, thereby improving the adsorption effect between the suction cup 511 and the back cover. After the welding operation is completed, the power rod 200 drives the welding head 300 and the pressure rod 501 to reset, so that the force rod 503 is unrestricted and moves upward under the action of the spring 505 to reset. Then the power rod 800 is activated to drive the elastic clamp 400 to reset.

[0036] Example 2, please refer to Figures 1-6Based on Embodiment 1, the cleaning component 600 includes a hydraulic chamber 601. A fixed seat 602 is mounted on the side of the welding chamber 100. A reciprocating screw 603 driven by a servo motor is rotatably connected inside the fixed seat 602. A sliding block 604 is threadedly connected to the outside of the reciprocating screw 603. The sliding block 604 is located inside the fixed seat 602 and is in a sliding connection with the fixed seat 602. An elastic cleaning plate 605 is mounted on the side of the sliding block 604. After the corresponding welding operation is completed, the servo motor is started, which drives the reciprocating screw 603 to rotate. Because the sliding block 604, which is threadedly mounted on the reciprocating screw 603, is restricted by the fixed seat 602, which is slidably connected to the sliding block 604, the sliding block 604 can reciprocate in the horizontal direction. The sliding block 604 can drive the elastic cleaning plate 605 mounted on its side to reciprocate, scraping off the welding slag at the bottom of the inner wall of the welding chamber 100.

[0037] A transmission rod 606 is slidably connected to one end of the hydraulic chamber 601. The transmission rod 606 is located on the side of the force-bearing rod 503 and is fixed to the force-bearing rod 503. A pressure plate 607 is slidably connected to the other end of the hydraulic chamber 601. A connecting plate 609 is connected to the top of the elastic cleaning plate 605 via an elastic telescopic rod 608. When the force-bearing rod 503 moves upward to reset, i.e., when the welding operation is completed, it drives the transmission rod 606, which is fixed to it, to move upward. This, in conjunction with the hydraulic chamber 601 slidably connected to the transmission rod 606, increases the pressure inside the hydraulic chamber 601, causing the pressure plate 607, which is slidably connected to the hydraulic chamber 601, to move downward. The pressure plate 607 then presses against the connecting plate 609 and applies an additional force to the elastic cleaning plate 605 via the elastic telescopic rod 608. This improves the cleaning effect of the elastic cleaning plate 605 on welding slag.

[0038] When the power rod 200 moves downward to restart the welding operation, the transmission rod 606 moves downward again, driving the pressure plate 607 and thus removing the restriction on the elastic cleaning plate 605. This facilitates the next use of the device.

[0039] In use, based on Embodiment 1, after completing the corresponding welding operation, the servo motor is started, driving the reciprocating screw 603 driven by the servo motor to rotate. Because the sliding block 604, which is threadedly mounted on the reciprocating screw 603, is restricted by the fixed seat 602 slidably connected to the sliding block 604, the sliding block 604 can reciprocate in the horizontal direction. The sliding block 604 can then drive the elastic cleaning plate 605 mounted on its side to reciprocate, scraping away the welding slag at the bottom of the inner wall of the welding chamber 100. When the force rod 503 moves upward to reset, This causes the transmission rod 606, which is fixedly connected to it, to move upward. In conjunction with the hydraulic chamber 601, which is slidably connected to the transmission rod 606, the pressure inside the hydraulic chamber 601 increases, causing the pressure plate 607, which is slidably connected to the hydraulic chamber 601, to move downward. The pressure plate 607 then squeezes the connecting plate 609 and applies an additional force to the elastic cleaning plate 605 through the elastic telescopic rod 608. When the power rod 200 moves downward to restart the welding operation, the transmission rod 606 moves downward again, driving the pressure plate 607, thereby removing the restriction on the elastic cleaning plate 605.

[0040] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, the cooling assembly 700 includes a fan drive shaft 701, a bevel gear 702 connected to the side of a reciprocating screw 603, a connecting block 703 rotatably connected to the side of a fixed base 602, and a bevel gear 704 fixedly connected to the side of the connecting block 703. The bevel gear 704 is located to the side of the bevel gear 702 and is meshed with it. When the reciprocating screw 603 rotates rapidly, i.e., when the welding operation is completed, the reciprocating screw 603 drives the bevel gear 702 connected to it to rotate, causing the bevel gear 702 to drive the bevel gear 704 meshing with it to rotate, and the bevel gear 704 drives the connecting block 703 fixedly connected to it to rotate.

[0041] A sprocket 705 is fixedly connected to the outer side of the connecting block 703. A chain 706 is mounted on the outer side of the sprocket 705, and a second sprocket 707 is mounted on the outer side of the fan drive shaft 701. When the connecting block 703 rotates, it drives the sprocket 705, which is fixedly connected to it, to rotate. This, in conjunction with the chain 706 mounted on the outer side of the sprocket 705, causes the second sprocket 707, which is driven by the chain 706 to rotate, to rotate. The second sprocket 707 then drives the fan drive shaft 701 to rotate, thereby activating the fan. In this way, the fan can be activated after welding to quickly cool the newly welded back cover, making the device easier to use.

[0042] In use, based on Embodiment 1 and Embodiment 2, when the reciprocating screw 603 rotates rapidly, i.e., when the welding operation is completed, the reciprocating screw 603 drives the bevel gear 702 connected to it to rotate, so that the bevel gear 702 drives the bevel gear 704 meshing with it to rotate, the bevel gear 704 drives the connecting block 703 fixedly connected to it to rotate, so that the connecting block 703 drives the sprocket 705 fixedly connected to it to rotate, and in conjunction with the chain 706 assembled on the outside of the sprocket 705, the sprocket 707 connected to the sprocket 705 via the chain 706 rotates, and the sprocket 707 then drives the fan power shaft 701 to rotate, thereby activating the fan.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
