[0038] The utility model is described in detail below in conjunction with the accompanying drawings.

[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] During the assembly stage of the battery, materials such as auxiliary sheets need to be welded to the battery body. During welding, the materials are placed in the welding grooves, and then the welding parts are pressed down to achieve welding. In order to improve welding efficiency, multiple welding grooves are usually set in the auxiliary welding block, and materials can be placed in each welding groove. After the material in the current welding groove is welded, the material in the next welding groove is welded. However, in the actual welding process, only the material currently being welded can be fixed, while the materials in other welding grooves are not fixed, and are prone to displacement and sliding due to the vibration of welding, resulting in a decrease in welding yield and the appearance of defective products. In order to solve such problems, the technical solution of this application is produced. Figure 1 to Figure 6 To elaborate.

[0041] Example 1

[0042] like Figure 1 , Figure 4 and Figure 5 As shown, this embodiment provides a welding auxiliary device 1, including a base 10, a first pressing member 20 and a second pressing member 30. The base 10 is used to connect the welding member 2, and the welding member 2 can be a welding head of a welding device. For example, the base 10 can be connected to the welding member 2 by welding, bolting, etc. The first pressing member 20 and the second pressing member 30 are both installed on the base 10.

[0043] The welding member 2 is used to weld the material in the first welding groove 3a of the auxiliary welding block 3, the first pressing member 20 is used to press the material in the first welding groove 3a, and the second pressing member 30 is used to press the material in the second welding groove 3b of the auxiliary welding block 3. The first welding groove 3a and the second welding groove 3b are adjacent. It can be seen that the auxiliary welding block 3 is used to accommodate and pre-position the material to facilitate the subsequent welding of the material.

[0044] In this way, when the material in the first welding groove 3a is fixed during the welding process, the material to be welded in the second welding groove 3b is also fixed, and the material to be welded in the second welding groove 3b will not be displaced or slipped due to vibration in the subsequent welding process, thereby ensuring the welding yield and avoiding the occurrence of defective products.

[0045] Optionally, the base 10 has a "T"-shaped structure as a whole. Specifically, the base 10 can be provided with a main body portion and wing portions located on both sides of the main body portion. The main body portion is used for installing the first clamping member 20 and the second clamping member 30, and the wing portions are connected to the welding member 2 through tie bolts. In this way, the connection points between the base 10 and the welding member 2 can be dispersed rather than being too dense, thereby improving the connection stability.

[0046] Alternatively, if Figure 1 to Figure 3As shown, the base 10 may be provided with a mounting hole 11, a portion of the first pressing member 20 may be slidably disposed in the mounting hole 11, and another portion of the first pressing member 20 extends out of the mounting hole 11 for pressing the material. The welding auxiliary device 1 also includes an elastic member 40, such as a spring, an elastic strip, etc. The elastic member 40 is arranged in the mounting hole 11 and is located between the first clamping member 20 and the bottom of the mounting hole 11; the sliding direction of the first clamping member 20 is the downward pressing direction of the welding member 2, and the elastic member 40 can be deformed with the sliding of the first clamping member 20. Specifically, in the process of the first clamping member 20 compressing the material, it will gradually retract into the mounting hole 11, accompanied by the compression of the elastic member 40, and the compression of the elastic member 40 in turn generates a driving force to drive the first clamping member 20 to compress the material. In this way, the first clamping member 20 can achieve flexible compression of the material, so as to control and adjust the compression force generated by the material, and avoid excessive impact force generated by rigid compression, which may cause damage to the compressed material or the first clamping member 20.

[0047] In other optional embodiments, the first clamping member 20 can also be set as an elastic telescopic member, and the telescopic direction is the downward pressing direction of the welding member 2, so as to cancel the setting of the elastic member 40, and the first clamping member 20 can also achieve flexible clamping of the material.

[0048] Optionally, the welding auxiliary device 1 may further include a plugging sleeve 50 disposed at the orifice of the mounting hole 11. The first clamping member 20 may be configured as a stepped shaft mechanism, specifically, the first clamping member 20 may include a pressure head 21 and a limiting portion 22 disposed in sequence, the limiting portion 22 being located in the mounting hole 11, the first portion of the pressure head 21 being located in the mounting hole 11 to connect the limiting portion 22, and the first portion of the pressure head 21 being movably provided with a plugging sleeve 50, so that the second portion of the pressure head 21 extends out of the mounting hole 11 to compress the material, and the intersection of the limiting portion 22 and the pressure head 21 forms a step surface facing the plugging sleeve 50. In this way, the plugging sleeve 50 can limit the first clamping member 20 to prevent the first clamping member 20 from excessive movement and separation from the base 10.

[0049] Optionally, an interference fit may be provided between the plug sleeve 50 and the mounting hole 11 to ensure the installation stability of the plug sleeve 50. An internal thread may also be provided at the opening of the mounting hole 11, and an external thread may be provided on the surface of the plug sleeve 50, and the plug sleeve 50 is threadedly connected to the mounting hole 11, so that the installation stability of the plug sleeve 50 is better and the disassembly, assembly, maintenance and replacement of the plug sleeve 50 are easier to achieve.

[0050] Optionally, a first guide hole 201 is provided on one side of the first pressing member 20 facing the bottom of the mounting hole 11, and at least a portion of the elastic member 40 is accommodated in the first guide hole 201. This facilitates the installation of the elastic member 40 and enables the elastic member 40 to be guided, thereby preventing the elastic member 40 from being skewed or other abnormalities during the expansion and contraction process.

[0051] Similarly, the base 10 may be provided with a second guide hole 111, which is connected to the bottom of the mounting hole 11 to be arranged opposite to the first guide hole 201, and at least part of the elastic member 40 is arranged in the second guide hole 111 to improve the guiding effect on the elastic member 40.

[0052] Example 2

[0053] Based on the first embodiment, the present embodiment further describes the structure of the welding auxiliary device 1 as follows:

[0054] like Figure 2 , Figure 3 and Figure 6 As shown, the second clamping member 30 may include a mounting portion 31 and a clamping portion 32. The mounting portion 31 is connected to the base 10 by bonding, welding, bolting, etc., and the clamping portion 32 is connected to the mounting portion 31 and is used to clamp the material. In this embodiment, the welding member 2 is directly opposite to the middle position of the first welding groove 3a, and the first clamping member 20 is used to be arranged close to the side edge of the first welding groove 3a, so as to avoid the welding member 2 while fixing the material, to prevent the welding member 2 from being blocked, so that the welding member 2 can more conveniently weld the material clamped by the first clamping member 20. The clamping portion 32 is used to be accommodated in the middle position of the second welding groove 3b. As mentioned above, the material clamped by the second clamping member 30 is located in the second welding groove 3b, which is the material waiting to be welded, so the clamping position of the second clamping member 30 is adjusted to the middle position to better ensure the clamping effect.

[0055] Optionally, the pressing portion 32 may be configured as a cubic column structure, and the end surface of the pressing portion 32 used to press the material is a rectangular surface to ensure the contact area with the material and improve the pressing effect.

[0056] Optionally, the second clamping member 30 can be set to be an elastomer, for example, it can be made of PU, which is also called polyurethane elastomer. It is a new type of material with good strength, small compression deformation, and is between plastic and rubber. It has the rigidity of plastic and the elasticity of rubber. In this way, it can not only ensure the clamping effect on the material, but also achieve buffering during clamping to a certain extent, preventing the rigid structure from causing excessive impact force when the second clamping member 30 contacts the material, resulting in abnormalities such as excessive squeezing and damage of the material.

[0057] Alternatively, if Figure 6As shown, a relief slope 321 is provided on one side of the clamping portion 32 toward the mounting portion 31 . The relief slope 321 is used to be provided toward the welding part 2 . The relief slope 321 can avoid the welding part 2 to prevent installation interference such as mutual extrusion between the welding auxiliary device 1 and the welding part 2 .

[0058] Optionally, a reinforcing rib 322 can be provided on the side of the clamping portion 32 close to the mounting portion 31, and the cross-sectional area of ​​the portion of the clamping portion 32 provided with the reinforcing rib 322 is greater than the cross-sectional area of ​​the portion of the clamping portion 32 without the reinforcing rib 322. In this way, the overall strength of the connection between the clamping portion 32 and the mounting portion 31 can be improved, preventing the second clamping member 30 from breaking or other abnormalities.

[0059] Example 3

[0060] like Figures 4 to 6 As shown, this embodiment discloses a welding device, including: a welding piece 2, an auxiliary welding block 3 and the above-mentioned welding auxiliary device 1. The welding auxiliary device 1 is connected to the welding piece 2, and the auxiliary welding block 3 is arranged opposite to the welding piece 2. The auxiliary welding block 3 is provided with a first welding groove 3a and a second welding groove 3b, respectively used to place materials. During welding, the welding piece 2 drives the welding auxiliary device 1 to move downward, so that the first clamping member 20 clamps the material in the first welding groove 3a, and the second clamping member 30 clamps the material in the second welding groove 3b. Each material is in a fixed state, thereby avoiding displacement and sliding of the material due to the vibration of welding, thereby avoiding the occurrence of defective products and improving the welding yield.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
