Description

Technical Field

[0001] This utility model relates to a welding fixture for protective plates, and belongs to the field of protective plate welding technology. Background Technology

[0002] A lithium battery protection board is a key component manufactured using high-tech methods. It is primarily used to protect lithium batteries and improve their performance. The protection board effectively provides necessary protection during the charging and discharging process, preventing battery damage and ensuring the battery's stability and reliability under various conditions. The protection board is typically welded onto the battery pack, requiring the use of clamping fixtures during the welding process.

[0003] Compare this to the patent document publication number: "CN211966490U: A lithium-ion battery protection board welding fixture, including a fixture main board, the fixture main board is provided with a positioning groove for fixing the battery, the positioning groove includes a first positioning groove and a second positioning groove, a protection board fixing groove is provided between the first positioning groove and the second positioning groove, a battery clamping plate is provided on the positioning groove, and the battery clamping plate is elastically connected to the fixture main board through a locking device."

[0004] The aforementioned patent still has the following problems in practical use: Although the patent can perform routine clamping operations on the protection plate, in actual use, due to the special structural design of the currently used clamps, their width is relatively fixed and difficult to adjust flexibly; only the length of the clamp can be adjusted to a limited extent. This characteristic directly results in a narrow range of lithium battery specifications that the clamp can accommodate, only suitable for lithium battery types of specific lengths and widths that meet its fixed standards, thus limiting the use of the clamp. Furthermore, in actual production operations, because the lithium batteries to be welded are usually thin, after the welding process is completed, the lithium batteries tend to be tightly embedded in the clamp and difficult to detach automatically. Workers must manually remove them from the clamp, further complicating the ease of use of the clamp. Utility Model Content

[0026] Example 1

[0027] This utility model provides a protective plate welding and fixing clamp.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a placement rack 1, which holds a lithium battery 3 and a protection plate body 5. A first placement groove 2 is provided on one side of the placement rack 1, with the lithium battery 3 placed on its inner wall. A second placement groove 4 is provided on the other side of the placement rack 1, with the protection plate body 5 placed on its inner wall. A fixing frame 6 is fixed to the lower end of the placement rack 1. A connecting structure is provided in the middle of the fixing frame 6. The connecting structure includes a limiting rod 7, with springs 8 sleeved on both sides of the limiting rod 7. Sliding frames 9 are slidably connected to the outer surfaces of both sides of the limiting rod 7. Hinges 10 are rotatably connected to both ends of the two sliding frames 9. Stabilizers 11 are slidably connected to the disjoint ends of the two hinges 10. Stabilizer grooves 12 are provided in the middle of both stabilizers 11. A first limiting frame 13 is fixed to the middle of both stabilizers 11. A second limiting frame 14 is fixed to one end of each stabilizer 11. A connecting frame 15 is rotatably connected to the other end of each stabilizer 11. A third limiting frame 16 is rotatably connected to the other end of each connecting frame 15.

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4It is worth noting that the two ends of the limiting rod 7 are fixed to the middle of the fixed frame 6. The middle of the two sliding frames 9 is slidably connected to the outer surfaces of the two sides of the limiting rod 7. The outer surfaces of the two sliding frames 9 are slidably connected to the inner walls of the two sides of the fixed frame 6. The two sliding frames 9 are fixed to the near ends of the two springs 8 on opposite sides. The two springs 8 are fixed to the opposite ends of the fixed frame 6 on opposite sides. The near ends of the two hinge frames 10 are rotatably connected to the two ends of the two sliding frames 9. The opposite ends of the two hinge frames 10 are slidably connected to the inner walls of the two sides of the two stabilizing grooves 12. The outer surfaces of the two first limiting frames 13 are slidably connected to the inner walls of the two sides of the first placement groove 2. The cross-section of each first limiting frame 13 is T-shaped. The outer surfaces of the two second limiting frames 14 are slidably connected to the inner walls on both sides of the second placement groove 4. The cross-sections of the two second limiting frames 14 are T-shaped. The outer surface of the third limiting frame 16 is slidably connected to the inner wall of the first placement groove 2. The two connecting frames 15 are rotatably connected at opposite ends to one end of the two stabilizing frames 11. The two connecting frames 15 are rotatably connected at near ends to both ends of the third limiting frame 16. The two first limiting frames 13 pass through both sides of the placement frame 1 and are in contact with both sides of the lithium battery 3. The two second limiting frames 14 pass through both sides of the placement frame 1 and are in contact with both sides of the protective plate body 5. The third limiting frame 16 is in contact with the outer surface of the lithium battery 3 on the side away from the tab.

[0030] In use, this invention works as follows: Two stabilizing frames 11 are manually pulled apart. During this process, two hinged frames 10, slidably connected to the inner wall of the stabilizing groove 12 in the middle of the two stabilizing frames 11, are linked together. This causes two sliding frames 9 to move closer together under the limiting action of the inner wall of the fixed frame 6 and the limiting rod 7, thereby stretching the two springs 8 fixed on the separated sides and causing them to generate elasticity. Simultaneously, the first limiting frame 13 and the second limiting frame 14 fixed to the two stabilizing frames 11 also move apart. Through the rotating connecting frame 15, the third limiting frame 16 slides to a specific position on the side of the first placement groove 2, a position that does not affect the placement of the lithium battery 3. Then, the lithium battery 3 can be placed in the first placement groove 2, and the protective plate body 5 can be placed in the second placement groove 4. Then, the applied force is released, and the elastic force generated by the stretched spring 8 will take effect. On the one hand, it will drive the two first limiting frames 13 to clamp and fix the two sides of the lithium battery 3; on the other hand, it will drive the two second limiting frames 14 to clamp the two sides of the protective plate body 5. In addition, it can also drive the third limiting frame 16 to clamp the tail of the lithium battery 3. Through the above series of actions, an adaptive clamping effect is achieved, making the fixing fixture applicable to a wider range of product sizes, thereby improving the versatility of the fixing fixture.

[0031] Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, a convenient retrieval function has been added;

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that a groove 17 is provided in the middle of the placement rack 1, and a pusher rack 18 is slidably connected to the inner wall of the groove 17. A protrusion 19 is fixed at the lower end of the pusher rack 18. The outer surface of the pusher rack 18 is in contact with the lower surface of the lithium battery 3. The vertical section of the pusher rack 18 is T-shaped. The upper end of the protrusion 19 is fixed in the middle of the lower end of the pusher rack 18. The lower end of the protrusion 19 is arc-shaped. The outer surface of the protrusion 19 is in contact with the upper surfaces of the two sliding racks 9.

[0034] In use, after welding, the two stabilizing frames 11 are manually pulled apart. During this process, the two hinged frames 10, which are slidably connected to the inner wall of the stabilizing groove 12 in the middle of the two stabilizing frames 11, are linked together, causing the two sliding frames 9 to move closer together under the limiting action of the inner wall of the fixed frame 6 and the limiting rod 7. At this time, the two sliding frames 9 that are moving closer together will apply a squeezing force to the arc-shaped protrusion 19, causing the protrusion 19 to slide upward in a specific direction. The push frame 18, which is fixed to the protrusion 19, will slide upward synchronously under the limiting constraint of the sliding groove 17. In this way, an upward pushing force can be applied to the lithium battery 3 placed in the fixture, causing the lithium battery 3 to move upward a certain distance. This design effectively achieves the effect of conveniently picking up the lithium battery 3, creating convenient conditions for the operator to pick up the battery, thereby improving the ease of use of the fixing fixture.
