A first motor 9 is fixedly installed inside the installation groove, and a first threaded rod 10 is transmission-connected to the output end of the first motor 9. One end of the first threaded rod 10 is rotatably connected to a connecting plate, and the other end of the first threaded rod 10 is threadedly connected to a first threaded block 11. The bottom of the first threaded block 11 is slidably connected to the bottom inner wall of the installation groove, and rotating rods 12 are hinged on both sides of the first threaded block 11. A moving block 13 is hinged on one end of the rotating rod 12, and a fixed plate 14 is fixedly installed on one side of the moving block 13. Two clamping blocks 15 are arranged at the bottom of the fixed plate 14, a fixing groove is opened inside the fixed plate 14, and a clamping structure is arranged inside the fixing groove.

[0028] The battery is fixed on the welding platform, and the composite board is placed at the position of the battery that needs to be welded. The angle and position of the welding head 3 are adjusted by rotating the rotating frame 2, so that the welding head 3 and the pressing block 7 are moved to the top of the composite board and the battery. According to the length of the composite board, the first motor 9 is controlled by the control panel to drive the first threaded rod 10 to rotate. The first threaded block 11 is slidably connected to the inner wall of the mounting groove and moves toward the connecting plate along the first threaded rod 10. When the first threaded block 11 moves, the rotating rod 12 rotates, thereby pushing the moving block 13 to move along the inner wall of the mounting groove toward the outside of the mounting block 8. When the moving block 13 moves, it drives the fixed plate 14 and the clamping block 15 to move to both sides of the mounting block 8 at the same time. When the fixed plate 14 is adjusted, the support rod 6 and the mounting block 8 are moved downward, so that the fixed plate 14 moves to the top of both ends of the composite board. The two ends of the composite plate are fixed, the clamping blocks 15 are located on both sides of the composite plate, and the pressing block 7 is located at the position where the composite plate and the battery need to be welded, and then the clamping structure inside the fixing groove is adjusted according to the width of the composite plate, so that the clamping structure drives the clamping block 15 to move, and the two sides of the composite plate are fixed by the clamping block 15, so as to further improve the stability of the composite plate and the battery during welding, and at the same time, the composite plate can be fitted with the pole ear to prevent one end of the composite plate from tilting during welding, which affects the quality of welding, facilitates to improve the welding effect, and improves safety. After the fixation is completed, according to the workpiece material, the shape of the welding joint and the process requirements, the laser power, pulse width, frequency and other parameters are set, and the scanning path and welding speed are set according to the process instruction manual, and the welding head 3 is started so that the laser passes through the through hole to weld the pressing position of the pressing block 7.

[0029] like Figure 2 , Figure 3 , Figure 5 As shown, limiting rods 16 are arranged on both sides of the support rod 6, one end of the limiting rod 16 is fixedly installed on the bottom of the mounting plate 5, and the other end is fixedly installed on the top of the mounting block 8. A mounting opening is opened in the middle of the mounting block 8, and one end of the support rod 6 extends through the mounting opening to the bottom of the mounting block 8, and the through hole is coaxial with the laser head and one end of the pressing block 7.

[0030] The support rod 6 facilitates the installation of the pressing block 7, and the pressing block 7 presses the welding position to improve the accuracy of the welding position between the composite plate and the battery. The limiting rod 16 facilitates the fixing of the mounting block 8 on the support rod 6 to improve the stability of the mounting block 8 during installation. The through hole and the laser head and one end of the pressing block 7 are coaxial, so that when the welding head 3 is welding, the laser passes through the through hole to the position pressed by the pressing block 7, which facilitates the determination of the welding position, prevents the welding position from being offset, and improves the stability and accuracy of the welding position.

[0031] like Figures 4 to 5As shown, the connecting plate is located at one side of the mounting opening, and its bottom is fixedly mounted on the inner wall of the bottom of the mounting groove, the bottom of the moving block 13 is slidably connected to the inner wall of the bottom of the mounting groove, the moving block 13 is located on both sides of the support rod 6, and a slider 17 is fixedly connected to one side of the moving block 13. Two sliding grooves are provided on the inner wall of the mounting groove close to the through hole, and the slider 17 is slidably connected to the two sliding grooves respectively. One end of the moving block 13 passes through the mounting groove and extends to the outside of the mounting block 8. The moving block 13 and the fixed plate 14 are symmetrically arranged with the mounting block 8 as the center.

[0032] The connecting plate facilitates the first threaded rod 10 to remain stable during rotation. When the first motor 9 drives the first threaded rod 10 to rotate, so that the first threaded block 11 moves to push the rotating rod 12 to deflect, the moving block 13 moves along the inner wall of the mounting groove, and at the same time drives the slider 17 to move inside the slide groove. The moving block 13 is limited by the slider 17 to prevent the moving block 13 from completely moving to the outside of the mounting block 8, thereby making it inconvenient to move back to the inside of the mounting block 8. Adjustment is performed by moving the moving block 13 and the fixed plate 14. The symmetrically arranged moving block 13 and the fixed plate 14 facilitate fixing the two ends of the composite plate, thereby improving the stability of the composite plate and the battery during welding.

[0033] like Figure 6 to Figure 7 As shown, the clamping structure includes a second motor 18, and the output end of the second motor 18 is transmission-connected with a second threaded rod 19, one end of the second threaded rod 19 is threadedly connected with a second threaded block 20, both ends of the second threaded block 20 are hinged with a pushing rod 21, one end of the pushing rod 21 is hinged to the top of the clamping block 15, both ends of the second threaded block 20 are fixedly connected with a limiting rod, both ends of the limiting rod are fixedly installed with the inner wall of the fixed groove, the bottom of the fixed plate 14 is flush with the bottom of the pressing block 7, two moving openings are opened at the bottom of the fixed plate 14, a first connecting block 22 is arranged between the two moving openings, the first connecting block 22 is fixedly installed with the inner wall of the fixed groove, the second motor 18 is fixedly installed with the top of the first connecting block 22, the second threaded rod 19 is rotatably connected with the top inner wall of the fixed groove, and one end of the pushing rod 21 extends to the bottom of the fixed plate 14 through the moving opening.

[0034] The second motor 18 is installed through the first connecting block 22, and the second motor 18 is started to drive the second threaded rod 19 to rotate. Through the limiting effect of the limit rod, the second threaded block 20 moves upward along the second threaded rod 19, so that the push rod 21 is deflected, and one end of the push rod 21 passes through the moving opening to drive the clamping blocks 15 to move closer to each other, so that the clamping blocks 15 limit the two sides of the composite plate, further improving the stability of the composite plate and the battery during welding.

[0035] like Figure 3 , Figure 4 , Figure 8 , Fig. 9As shown, two connecting rods 23 are fixedly installed on the top of the opposite side of the fixed plate 14, and the two connecting rods 23 are slidably connected to the inner wall of one end away from the fixed plate 14, and a second connecting block 25 is fixedly connected to the middle of the fixed rod 24, and the top of the second connecting block 25 is fixedly installed with the bottom of the mounting block 8, and a weighting block 26 is fixedly installed on the right connecting rod 23 close to one end of the fixed plate 14, and two fixing rings 27 are fixedly installed on one end of the left connecting rod 23, and a protective block 28 is fixedly connected to the bottom of the two fixing rings 27, and a collecting box 29 is fixedly installed inside the protective block 28, and a connecting pipe 30 is fixedly connected to the bottom of the collecting box 29, and a suction pump 31 is fixedly installed on one end of the connecting pipe 30, an elastic telescopic tube 32 is fixedly installed on the bottom of the suction pump 31, and a suction head 33 is fixedly installed on the bottom of the elastic telescopic tube 32.

[0036] The fixing rod 24 is fixed by the second connecting block 25. When the moving block 13 drives the fixing plate 14 to move toward the two sides of the mounting block 8, the fixing plate 14 drives the connecting rod 23 to move along the fixing rod 24 in the direction away from the second connecting block 25, so as to improve the stability of the movement of the fixing plate 14. At the same time, the fixing ring 27 is fixed by the left connecting rod 23, and the connecting protection block 28 is fixed by the fixing ring 27. The weighting block 26 is fixed by the right connecting rod 23, so as to keep the connecting rods 23 on the left and right sides balanced, and prevent one end of the connecting rod 23 from being too heavy, resulting in imbalance of the fixing plates 14 on both sides, so that the fixing plate 14 is unstable when fixing the two ends of the composite plate, affecting the welding effect. By starting the suction pump 31, the suction head 33 absorbs the dust and impurities on the composite plate, and absorbs them into the collection box 29 through the elastic telescopic tube 32 and the connecting tube 30 for collection. Before the composite plate is welded, the composite plate is cleaned again, so as to prevent dust and impurities from affecting the effect of welding the composite plate and the battery.

[0037] like Figures 8 to 9 As shown, one side of the protective block 28 is fitted with one side of the fixed plate 14 close to the fixed ring 27, a movable plate 34 is fixedly installed in the middle of the elastic telescopic tube 32, an electric telescopic rod 35 is fixedly installed on the top of one end of the movable plate 34, the top of the electric telescopic rod 35 is fixedly installed on the bottom of the collecting box 29, a movable opening is opened at the bottom of the protective block 28, a rotating plate 36 is arranged at the bottom of the movable opening, one end of the rotating plate 36 is hinged to the bottom of the protective block 28, a connecting spring 37 is fixedly connected to the bottom of the rotating plate 36, and one end of the connecting spring 37 is fixedly installed on the bottom of the protective block 28.

[0038] The protective block 28 is convenient for protecting the suction head 33, the elastic telescopic tube 32, the suction pump 31 and the connecting tube 30 to prevent sparks from flying during welding and affecting the use. The movable plate 34 is pushed downward by the electric telescopic rod 35 to extend the elastic telescopic tube 32, thereby driving the suction head 33 to move downward, pushing the rotating plate 36 to rotate, and the connecting spring 37 contracts, so that the rotating plate 36 exposes the movable opening. When the suction head 33 moves to the bottom of the protective block 28, it is convenient to absorb dust and impurities on the composite board, so as to improve the cleanliness of the composite board. When the suction head 33 is located at the bottom of the protective block 28 , the movable plate 34 moves to the movable opening to resist the rotating plate 36, so that the rotating position of the rotating plate 36 is limited. When the composite plate is cleaned, the movable plate 34 is driven to move upward by the electric telescopic rod 35, and the suction head 33 is driven to move upward by the elastic telescopic tube 32. The movable plate 34 no longer resists the rotating plate 36. When one end of the suction head 33 reaches the inside of the protective block 28, the rotating plate 36 is connected to the spring 37 and rotates to the bottom of the movable opening to block the movable opening, thereby preventing sparks generated during welding from splashing into the inside of the protective block 28, affecting the suction head 33 and affecting the suction effect.

[0039] Working principle: When in use, check the status of the laser and optical path system, ensure that the gas source and cooling system are working properly, clean the welding work area, fix the battery on the welding platform, place the composite board on the part of the battery that needs to be welded, adjust the angle and position of the welding head 3 by rotating the rotating frame 2, so that the welding head 3 and the pressing block 7 move to the top of the composite board and the battery, and control the first motor 9 to rotate the first threaded rod 10 through the control panel according to the length of the composite board. The first threaded block 11 is slidably connected to the inner wall of the mounting groove and moves toward the connecting plate along the first threaded rod 10 at the same time. When the first threaded block 11 moves, the rotating rod 12 rotates, thereby pushing the moving block 13 to move along the inner wall of the mounting groove toward the outside of the mounting block 8, and the slider 17 on one side of the moving block 13 moves inside the slide groove. When the moving block 13 moves, it drives the fixed plate 14 and the clamping block 15 to move simultaneously to both sides of the mounting block 8. The movement of the fixed plate 14 drives the connecting rod 23 to move along the fixed rod 24 away from the second connecting block 25. When After the adjustment of the fixing plate 14 is completed, the support rod 6 and the mounting block 8 are moved downward so that the fixing plate 14 moves to the top of both ends of the composite plate to fix the two ends of the composite plate. The clamping blocks 15 are located on both sides of the composite plate, and the pressing blocks 7 are located at the positions where the composite plate and the battery need to be welded. Then, the position of the clamping block 15 is adjusted according to the width of the composite plate, and the second threaded rod 19 is driven to rotate by starting the second motor 18. Through the limiting effect of the limit rod, the second threaded block 20 moves upward along the second threaded rod 19, so that the push rod 21 is deflected, and one end of the push rod 21 passes through the moving port to drive the clamping blocks 15 to move closer to each other, so that the clamping blocks 15 limit the two sides of the composite plate. When the composite plate and the battery are fitted and fixed, according to the workpiece material, the shape of the welding joint and the process requirements, the laser power, pulse width, frequency and other parameters are set, and the scanning path and welding speed are set according to the process instruction book. By starting the welding head 3, the laser passes through the through hole to weld the pressing position of the pressing block 7.

[0040] When the fixed plate 14 and the clamping block 15 are located at the top of the composite plate, and the distance between the two fixed plates 14 is adjusted according to the size of the composite plate, the electric telescopic rod 35 is started to push the movable plate 34 to move downward, so that the elastic telescopic tube 32 is extended, the suction head 33 moves downward, and the rotating plate 36 is pushed to rotate, so that the connecting spring 37 is compressed. When the suction head 33 is completely moved to the bottom of the protective block 28 through the movable opening, the movable plate 34 moves to the movable opening and presses against the rotating plate 36, and then the suction pump 31 is started to move the support rod 6 and the mounting block 8 left and right, so that the suction head 33 is on the composite plate. The top moves back and forth to absorb impurities and dust on the composite plate. The absorbed impurities and dust are absorbed into the collection box 29 through the elastic telescopic tube 32 and the connecting tube 30 for collection. After the collection is completed, the electric telescopic rod 35 is started to drive the movable plate 34 to move upward, and the suction head 33 is driven to move upward by the contraction of the elastic telescopic tube 32. When the suction head 33 and the movable plate 34 move to the inside of the protective block 28, the rotating plate 36 is no longer subject to resistance. Under the elastic action of the connecting spring 37, the rotating plate 36 is rotated to the movable opening to cover the bottom of the protective block 28.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
