Description

Technical Field

[0001] This utility model relates to the field of battery tab processing technology, specifically a tab bending tool for battery plates. Background Technology

[0002] A storage battery consists of multiple electrode groups connected in series. After each electrode group is cast and welded, it is pressed and inserted into the corresponding cell in the battery box. In order to achieve the best welding effect and to prevent the welded part from interfering with the battery box during the insertion process, the electrode tabs of the two outer plates in the electrode group are usually required to form an inward tilt angle during the production process. This process is called electrode tab bending.

[0003] According to Chinese Patent No. CN219561025U, a tab bending device is proposed, which includes a base device for fixing support and driving up and down movement. The bottom of the base device is provided with a support device for supporting the tab processing and telescopic completion of material discharge. It also includes a lifting device for driving the tab downward to flatten it and providing rotational power. The top of the lifting device is provided with a forming device for preheating the tab and bending it into shape.

[0004] In the above solution, the design of using a lifting platform to lower the pressure block to clamp the tabs completes the fixing of the tabs while flattening them, preventing other parts of the tabs from deforming during bending and making the bending more accurate. However, generally speaking, the bending angle is controlled within a certain range, such as between 10° and 50°, but the specific value needs to be determined according to the actual situation. In the above technology, the position of the pressure block and the angle of the forming groove are fixed, which makes it impossible to adjust the bending angle of the battery tabs, which has certain limitations.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a fixture for bending the tabs of a battery plate, including a base 1 and a mounting bracket 2. The mounting bracket 2 is fixedly mounted on the top of the base 1. An angle line 21 is provided on the surface of the mounting bracket 2. A drive motor 3 is fixedly mounted on the surface of the mounting bracket 2. A mounting shaft 31 is fixedly connected to the output end of the drive motor 3. A cam 32 is fixedly mounted on the surface of the mounting shaft 31. A placement plate 4 is provided on the inner side of the mounting bracket 2. A fixing seat 5 is fixedly connected to the top of the base 1. A guide rod 51 is fixedly mounted inside the fixing seat 5. A mounting plate 5 is fixedly connected to the outer wall of the fixing seat 5. 2. An adjusting plate 6 is slidably mounted on the surface of the guide rod 51. A cylinder 7 is fixedly mounted on the top of the adjusting plate 6. A pressure block 71 is fixedly connected to the output shaft of the cylinder 7. The mounting bracket 2 is concave. A baffle 41 is fixedly mounted on the top of the placement plate 4. A connecting shaft 42 is fixedly mounted inside the placement plate 4. The connecting shaft 42 is movably mounted on the inner side of the mounting bracket 2. One end of the connecting shaft 42 extends outward to the outer end of the mounting bracket 2. A pointer 43 is fixedly connected to the outer wall of the extended end of the connecting shaft 42. One end of the mounting shaft 31 is movably connected to the inner side of the mounting bracket 2. The top of the cam 32 is in contact with the bottom of the placement plate 4.

[0025] In this embodiment, the placement plate 4 and the mounting bracket 2 are connected by a connecting shaft 42. One bottom end of the placement plate 4 is supported by the cam 32, and the placement plate 4 is in a horizontal state. By starting the drive motor 3 to drive the mounting shaft 31 to rotate, the cam 32 can be driven to rotate, thereby gradually lifting the placement plate 4 upward, so that the placement plate 4 is in an inclined state, which facilitates the corresponding adjustment of the bending angle of the battery tab. The pointer 43 at one end of the connecting shaft 42 points to the angle line 21. When the placement plate 4 rotates, the rotation range of the placement plate 4 can be determined by observing the rotation angle of the pointer 43.

[0026] Example 2

[0027] like Figures 1-5 As shown, a limiting rod 72 is fixedly connected to the top of the pressure block 71. The limiting rod 72 moves through the interior of the adjusting plate 6. A handle 8 is provided on one side of the mounting plate 52. A screw 81 is fixedly connected to the side of the handle 8. The outer surface of the screw 81 is threadedly connected to the inner wall of the mounting plate 52. One end of the screw 81 is fixedly connected to one side of the outer wall of the adjusting plate 6.

[0028] In this embodiment, the output end of cylinder 7 is connected to the top of pressure block 71. The height of pressure block 71 can be adjusted by controlling the extension and retraction of the piston rod of cylinder 7 through an external power supply. By lowering pressure block 71, the battery folding lug is bent. When pressure block 71 moves, limit rod 72 slides vertically inside adjustment plate 6, improving the stability of pressure block 71 during movement. When the angle of placement plate 4 is adjusted, the placement position of battery folding lug will also change accordingly. Adjustment plate 6 is slidably mounted on the surface of guide rod 51, and one end is connected to screw 81. Rotating handle 8 causes screw 81 to rotate and move, thereby adjusting the position of adjustment plate 6 and pressure block 71. When placing plate 4 is adjusted, the position of pressure block 71 can be aligned with the folding end of battery.

[0029] Working principle: Place the battery panel to be processed on top of the placement plate 4, with the baffle 41 aligned and positioned. Press the battery panel by hand. Start the drive motor 3 to rotate the mounting shaft 31, which in turn rotates the cam 32, gradually lifting the placement plate 4 upwards. Observe the rotation angle of the pointer 43 to determine the rotation range of the placement plate 4, and correspondingly determine the angle after the folded ear is bent. Adjust the placement plate 4 to a suitable angle, with the folded end of the battery panel located at the top of the inclined placement plate 4 and extending to the side of the placement plate 4. Then, rotate the handle 8 to rotate and move the screw 81, adjusting the position of the adjusting plate 6 and the pressure block 71 so that the position of the pressure block 71 is aligned with the folded end of the battery. Then, use an external power source to control the extension and retraction of the piston rod of the cylinder 7, lowering the pressure block 71 to bend the battery folded ear. This allows for bending of the battery panel folded ear at different angles.
