[0002] The existing battery cell pressing tool structure is a hollow circular disk fixed at two points. When fixing the welding wire of the battery cell with glue brushing, the glue can only be partially removed, and it cannot be guaranteed that the welding wire is completely pressed to remove the glue, resulting in the welding wire not being completely immersed in the welding glue. This in turn affects the heating of the battery cell in the curing furnace. The glue and welding wire on the battery cell will be heated unevenly, resulting in poor welding.

[0003] Furthermore, the through-length pressure strips used in the existing press structure need to be installed on the connecting column first and then connected to the press seat through the connecting column, which adds a lot of unnecessary connecting parts and wastes a lot of cost and assembly time.

[0006] Furthermore, in the present invention, the spacing between two adjacent rows of pressing tool units is the same, and the spacing between two adjacent pressing blocks in the same column is the same.

[0007] Furthermore, the anti-rotation mechanism described in the utility model includes a guide groove opened on the press seat, and a protrusion that cooperates with the guide groove is provided on the cylindrical part. The cylindrical part can be slidably installed in the guide groove through a spring, and the two ends of the spring are respectively against the guide groove and the protrusion, and the end of the cylindrical part passes through the press seat and is fixed by a retaining ring.

[0008] Furthermore, the magnetic fixing seat in the utility model is provided with a knurled pattern.

[0009] Furthermore, the anti-slip pad in the utility model is a rubber pad.

[0010] Furthermore, the anti-slip pad in the utility model protrudes from the bottom surface of the press seat by 0.5 mm.

[0011] Compared with the prior art, the utility model has the following advantages: the press of the utility model adopts an integrated press block combination installation, which can save a lot of unnecessary connecting parts and make assembly simpler. The press block is specially designed. After it is inserted into the press seat and abutted against the spring, it can be fixed with a retaining ring to complete the assembly. The spring plays a certain buffering role to prevent the battery cell from being cracked when pressed down.

[0019] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0020] Example:

[0021] The accompanying drawings show a specific embodiment of an integrated press block assembly press for fixing welding wires on a battery cell according to the present invention. Figure 1 It mainly includes a press seat 1, on which 24 rows of press units 2 are evenly spaced. Each press unit 2 includes 6 pressing blocks 3 arranged in a row for cooperating in segmented pressing of the same welding wire b, and the distance between two adjacent pressing blocks 3 in the same row is the same.

[0022] In this embodiment, combined with Figure 3 , Figure 4 The pressing block 3 includes an integrally formed cylindrical portion 31 and a block portion 32. The cylindrical portion 31 is elastically mounted on the press seat 1, and an anti-rotation mechanism is provided between the cylindrical portion 31 and the press seat 1. Specifically, the anti-rotation mechanism includes a guide slot 1a provided on the press seat 1, and a protrusion 31a matching the guide slot 1a is provided on the cylindrical portion 31. The cylindrical portion 31 is slidably mounted in the guide slot 1a through a spring 6, and the two ends of the spring 6 are respectively against the guide slot 1a and the protrusion 31a, and the end of the cylindrical portion 31 passes through the press seat 1 and is fixed by a retaining ring 7. The block portion 32 is connected below the cylindrical portion 31 and is used to press down the welding wire b.

[0023] The design of the integrated pressure block 3 can save a lot of unnecessary connectors, making assembly easier. When installing it, it only needs to be inserted into the guide slot 1a of the press seat 1 and fixed with the retaining ring 7 after it abuts against the spring 6. The spring 6 plays a certain buffering role, which can prevent the battery cell from cracking due to excessive downward pressure. Through the cooperation of the protrusion 31a and the guide slot 1a, the pressure block 3 will not rotate, thereby avoiding rotation during the process of pressing the welding wire, causing the press to deflect the welding wire. The problem of the pressure block 3 getting stuck can also be solved well by sliding up and down.

[0024] A magnetic fixing seat 4 is provided on both sides of the press seat 1, and a knurled pattern 41 is provided on the magnetic fixing seat 4. Figure 1 As shown. The magnetic fixing seat 4 can be used for synchronous transportation of the press and the battery cell, which is convenient for the transportation mechanism to simultaneously adsorb the press (magnetic attraction) and the battery cell (vacuum attraction). The knurled pattern 41 on the magnetic fixing seat 4 can reduce the magnetic contact area and prevent the pressure tool from being slightly driven by the electromagnet when the pressure tool is placed when it is taken or placed, causing damage to the electromagnetic sheet or displacement of the welding wire fixing position.

[0025] The bottom of the press seat 1 is provided with an anti-skid pad 5, which is a rubber pad. Figure 2As shown, the anti-skid pad 5 protrudes 0.5 mm from the bottom surface of the press seat 1. In this embodiment, a total of four rubber pads 5 are installed at the bottom of the press seat 1 to increase friction and prevent slipping on the curing line, thereby causing damage to the battery cell and displacement of the welding wire position.

[0026] The pressing state of the press of the utility model is as follows Figure 5 As shown, combined with Figure 6 The pressing block 3 of the pressing tool is pressed down on the welding wire b. Through the cooperation of the magnetic fixing seats 4 on both sides and the magnets on the curing line bottom plate 8 (magnets are not shown), they attract each other to generate a certain suction force. The pressing block 3 exerts downward pressure on the welding wire b, making the welding wire b easy to sink into the welding glue a. 0 To ensure good curing effect.

[0027] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
