The connection between the battery connecting plate and the lithium batteries is achieved by welding using a welding galvanometer.

[0003] Existing welding methods make it difficult to rotate the battery, limiting welding to one side only and hindering welding to the other side. Welding the other side requires manual operation, which is inconvenient and affects welding efficiency. Therefore, a multi-station rotary battery module welding fixture is proposed. Utility Model Content

[0004] This utility model proposes a multi-station rotary battery module welding fixture, which solves the problem in the existing related technologies that it is difficult to rotate the battery during welding, thus only one side of the battery can be welded, making it inconvenient to weld the other side of the battery. Welding the other side of the battery also requires manual operation, which is more troublesome and affects the welding efficiency.

[0005] The technical solution of this utility model is as follows: A multi-station rotary battery module welding fixture, comprising: a fixture table;

[0006] Two hydraulic rods are fixedly installed at the bottom of the fixture table. The output ends of the two hydraulic rods are movably connected to a U-shaped plate through the fixture table. Two rotating rods are rotatably connected to the inner wall of the U-shaped plate. A rectangular frame is fixedly connected to one end of the two rotating rods. A first synchronous wheel is fixedly installed on the outer wall of the two rotating rods.

[0007] A connecting rod is rotatably connected to two fixed plates that are relatively fixedly installed on the top of the U-shaped plate. Both ends of the outer wall of the connecting rod are fixedly connected to a second synchronous pulley. The second synchronous pulley and the first synchronous pulley are tensioned together by a synchronous belt.

[0008] A first gear is fixedly installed at the center of the outer side wall of the connecting rod, a motor is fixedly installed on the rear side of the U-shaped plate, and a second gear is fixedly connected to the output end of the motor;

[0010] Preferably, the clamping mechanism includes multiple electric push rods fixedly installed on both sides of the rectangular frame, and the output ends of the multiple electric push rods movably pass through the rectangular frame and are fixedly connected to a clamping plate.

[0011] Preferably, two sliding grooves are provided through the front side of the U-shaped plate, and multiple trapezoidal grooves are provided on both sides of the U-shaped plate from top to bottom, with the multiple trapezoidal grooves connected to the two sliding grooves.

[0012] Preferably, two V-shaped plates are fixedly installed on the top of the fixture table, and the two V-shaped plates are slidably connected to the two slide grooves.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] By placing the battery module to be welded on the fixture table, and then activating the hydraulic rod, the hydraulic rod retracts, causing the clamping mechanism to move downwards and clamp the battery module. After clamping, activating the hydraulic rod again pushes the U-shaped plate upwards, moving the rectangular frame away from the fixture table. Then, activating the motor drives the second gear to rotate, which in turn meshes with the first gear connected to the second gear, causing the connecting rod to rotate on the two fixed plates. This, in turn, drives the second synchronous pulley to rotate, which in turn drives the synchronous belt to rotate, and the synchronous belt drives the first synchronous pulley to rotate. This achieves the purpose of rotating the battery to be welded, facilitating the welding process without the need for manual operation, effectively improving work efficiency.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] Please see Figure 1 - Figure 4 A multi-station rotary battery module welding fixture, comprising: fixture table 1;

[0026] Two hydraulic rods 19 are fixedly installed at the bottom of the fixture table 1. The output ends of the two hydraulic rods 19 are movably connected to a U-shaped plate 2 through the fixture table 1. Two rotating rods 3 are rotatably connected to the inner wall of the U-shaped plate 2. A rectangular frame 4 is fixedly connected to one end of the two rotating rods 3. A first synchronous wheel 5 is fixedly installed on the outer wall of the two rotating rods 3.

[0027] A connecting rod 6 is rotatably connected to two fixed plates that are relatively fixedly installed on the top of the U-shaped plate 2. The two ends of the outer side wall of the connecting rod 6 are fixedly connected to the second synchronous pulley 7. The second synchronous pulley 7 and the first synchronous pulley 5 are tensioned together by a synchronous belt 8.

[0028] The first gear 9 is fixedly installed at the center of the outer side wall of the connecting rod 6, and the motor 10 is fixedly installed on the rear side of the U-shaped plate 2. The output end of the motor 10 is fixedly connected to the second gear 11.

[0029] Clamping mechanisms 12 are set on both sides of the rectangular frame 4.

[0030] The technical solution provided by this utility model is as follows: The battery module to be welded is placed on the fixture table 1. Then, by activating the hydraulic rod 19, the hydraulic rod 19 retracts, causing the clamping mechanism 12 to move downwards and clamp the battery module. After clamping, by activating the hydraulic rod 19 again, the hydraulic rod 19 pushes the U-shaped plate 2 upwards, moving the rectangular frame 4 away from the fixture table 1. Then, by activating the motor 10, the motor 10 drives the second gear 11 to rotate, and in conjunction with the first gear 9 connected to the second gear 11, the first gear 9 rotates, causing the connecting rod 6 to rotate on the two fixed plates. This, in turn, drives the second synchronous wheel 7 to rotate, which in turn drives the synchronous belt 8 to rotate, and the synchronous belt 8 drives the first synchronous wheel 5 to rotate. This achieves the purpose of rotating the battery to be welded, facilitating welding without the need for manual operation, effectively improving work efficiency.

[0031] Furthermore, two sliding grooves 13 are opened through the front side of the U-shaped plate 2. Multiple trapezoidal grooves 14 are opened from top to bottom on both sides of the U-shaped plate 2. The multiple trapezoidal grooves 14 are connected to the two sliding grooves 13. Two V-shaped plates 15 are fixedly installed on both sides of the top of the fixture table 1. The two V-shaped plates 15 are slidably connected to the two sliding grooves 13. An installation groove 16 is opened on one side of the two V-shaped plates 15. Multiple springs 17 are fixedly installed on the inner wall of the installation groove 16. One end of the multiple springs 17 is fixedly connected to a trapezoidal block 18. The trapezoidal block 18 is inserted into one of the multiple trapezoidal grooves 14.

[0032] Specifically, when the U-shaped plate 2 moves upward, the trapezoidal groove 14 squeezes the trapezoidal block 18 using the upward force, causing the spring 17 to contract. At this time, the trapezoidal block 18 disengages from the trapezoidal groove 14. When the U-shaped plate 2 moves to the required height, the spring 17 drives the trapezoidal block 18 to return to its original position. The trapezoidal block 18 is then inserted into the trapezoidal groove 14 for limiting and fixing, thereby achieving the purpose of supporting the U-shaped plate 2 through the V-shaped plate 15, effectively improving the stability of the U-shaped plate 2.

[0033] Example 2

[0034] Based on Embodiment 1, in this embodiment: the clamping mechanism 12 includes multiple electric push rods 120 fixedly installed on both sides of the rectangular frame 4, and the output ends of the multiple electric push rods 120 movably pass through the rectangular frame 4 and are fixedly connected to the clamping plate 121.

[0035] The technical solution provided in this embodiment is as follows: by activating the electric push rod 120, the electric push rod 120 pushes the clamping plate 121 to clamp the battery module. At the same time, multiple clamping plates 121 can clamp multiple battery modules, thereby realizing multi-station welding of battery modules and effectively improving work efficiency.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
