Description

Technical Field

[0001] This utility model relates to the technical field of battery welding devices, specifically a fixing device for battery processing. Background Technology

[0002] With the development of lithium batteries, battery structures are becoming increasingly diversified. Among them, blade batteries have been widely used due to their unique performance. Compared with VDA prismatic batteries, blade batteries are longer and mostly use side welding processes. In addition, multiple batteries can be assembled by welding to meet the requirements of increasing battery capacity and voltage. However, the existing welding equipment and the long length of blade batteries make it difficult to weld single cells. When it is necessary to weld battery combinations to increase capacity and voltage, the welding line is longer and the welding difficulty is greater. Therefore, this application reduces the welding difficulty by improving the welding positioning device. Utility Model Content

[0016] By setting two welding nozzles, the two ends of the battery can be pressed together and welded.

[0017] As a further embodiment of this utility model, both the first welding nozzle and the second welding nozzle are provided with welding through grooves.

[0018] By providing a welding groove on the welding nozzle, it is convenient to weld the battery, tabs, and cover plate below the welding nozzle.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1In this embodiment of the present invention, a fixing device for battery processing includes a base 1. A left side plate 2 and a right side plate 3 are arranged in parallel on the upper end of the base 1. Ribs 4 are provided between the outer sides of the left side plate 2 and the right side plate 3 and the base 1. In this embodiment, multiple ribs 4 are provided. By providing multiple ribs 4, the connection strength between the left side plate 2, the right side plate 3 and the base 1 can be increased. A reinforcing plate 5 is fixedly connected to the end of the left side plate 2 and the right side plate 3 away from the end limiting component. In this embodiment, the reinforcing plate 5 has a U-shaped structure. The two sides of the reinforcing plate 5 are fixedly connected to the left side plate 2 and the right side plate 3 respectively. The ends of the left side plate 2 and the right side plate 3 are reinforced and fixed by the reinforcing plate 5, thereby increasing the connection strength between the left side plate 2 and the right side plate 3.

[0029] A second working support plate 16 is fixedly connected between the left side plate 2 and the right side plate 3. A first working support plate 6 is provided above the second working support plate 16. An installation groove 19 is provided between the first working support plate 6 and the right side plate 3 for inserting the battery to be welded into the installation groove 19 so that the small faces on both sides of the battery can be welded. A welding nozzle is provided above the first working support plate 6 and is movably connected to the left side plate 2 and the right side plate 3. In this embodiment, the welding nozzle includes a first welding nozzle 7 and a second welding nozzle 8. Both the first welding nozzle 7 and the second welding nozzle 8 are provided with welding through grooves. By providing welding through grooves on the welding nozzles, it is convenient to weld the battery, the tabs, and the cover plate below the welding nozzles. The first welding nozzle 7 is movably connected to the left side plate 2 and the right side plate 3 on both sides through the first nozzle locking buckle 9. The second welding nozzle 8 is movably connected to the left side plate 2 and the right side plate 3 on both sides through the second nozzle locking buckle 10. By providing two welding nozzles, the two ends of the battery can be pressed and welded.

[0030] An end limiting assembly is provided at one end of the left side plate 2 and the right side plate 3. An end limiting plate 15 is provided between the left side plate 2 and the right side plate 3. The end limiting assembly includes a vertical plate 11 fixedly connected to the base 1. A screw 12 is threadedly connected to the vertical plate 11. An adjusting limiting plate 14 is slidably connected to the side of the left side plate 2 and the right side plate 3 near the screw 12. The screw 12 is rotatably connected to the adjusting limiting plate 14. An adjusting wheel 13 is provided at the other end of the screw 12. The adjusting limiting plate 14 is slidably connected to the end of the left side plate 2 and the right side plate 3. When the screw 12 is rotated, it will move closer to or away from the first working support plate 6. In conjunction with the end limiting plate 15, the battery to be welded placed between the adjusting limiting plate 14 and the end limiting plate 15 can be pressed and released.

[0031] like Figure 2As shown, a clamping plate 20 is provided above the second working support plate 16 and is movably connected to the left side plate 2. The left side plate 2 is provided with a through hole, and a movable rod 17 is inserted into the through hole. The left side plate 2 is provided with a wrench 18 for pushing the movable rod 17. The end of the movable rod 17 away from the wrench 18 is connected to the clamping plate 20.

[0032] By turning the wrench 18, the movable rod 17 is moved, which in turn pushes the clamping plate 20 to move horizontally on the second working support plate 16, making it convenient to clamp and release the upright battery.

[0033] In this embodiment, the battery is first placed on the first working support plate 6, and then the adjusting wheel 13 is rotated. The adjusting wheel 13 drives the screw 12 to rotate. Since the screw 12 is threadedly connected to the upright plate 11, the screw 12 will move towards the first working support plate 6, thereby pushing the adjusting limit plate 14 towards the first working support plate 6. The adjusting limit plate 14 and the end limit plate 15 limit and fix the battery placed on the first working support plate 6. Then, the tabs and / or cover plates are placed at both ends of the battery cell and the first welding nozzle 7 and the second welding nozzle 8 are pressed to the side of the battery by the first nozzle lock 9 and the second nozzle lock 10. Then, the edge of the battery surface, as well as the battery tabs and cover plates, can be welded.

[0034] Alternatively, two batteries can be placed on the first working support plate 6, stacked together, and then pressed simultaneously onto the first working support plate 6. The two batteries can then be welded together, and the electrodes of the two batteries can be connected in series or in parallel as needed to form a series or parallel battery pack.

[0035] After the horizontally placed battery is welded, it can be rotated 90° and inserted into the mounting slot 19. At this time, the bottom of the battery is located on the second working support plate 16. Then, turn the handle 18 to drive the movable rod 17 to extend and push the clamping plate 20 to press the battery. At the same time, a battery is fixed on the first working support plate 6. In this way, a horizontally arranged battery is placed on the first working support plate 6 and a vertically arranged battery is placed in the mounting slot 19. The two batteries can be welded at the same time, which increases the efficiency of the equipment.
