Therefore, it cannot be understood as a limitation on the present utility model.

[0031] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0032] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0033] As mentioned in the background technology, in the manufacturing process of the battery pack, some process flows require the liquid cooling plate (for example, the liquid cooling plate includes two aluminum plates) to be welded to ensure strength and sealing. In the prior art, generally speaking, a pressing plate is used to press the two aluminum plates together manually, but there may be a gap after pressing, resulting in insufficient welding strength and unsatisfactory sealing. Although some solutions can use quick clamps on the base plate to clamp the aluminum plate, there is a situation where the laser power is too high and the aluminum plate is welded through, causing the aluminum plate and the base plate to be welded together, affecting the normal processing flow.

[0034] In view of this, please refer to Figure 1-Figure 5 The welding tooling provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0035] Please refer to Figure 1 and Figure 2 In an embodiment of the utility model, a welding tool is provided, which includes a base plate 100 and a clamping mechanism 200. The base plate 100 is used to support the liquid cooling plate 10. The base plate 100 is provided with a welding reserved groove 101. The welding reserved groove 101 is used to be covered by the welding periphery of the liquid cooling plate 10. The clamping mechanism 200 is arranged on the base plate 100, and the clamping mechanism 200 is used to press the liquid cooling plate 10 on the base plate 100.

[0036] Since the base plate 100 is provided with a welding reserved groove 101, when the welding periphery of the liquid cooling plate 10 is welded by laser welding, even if the liquid cooling plate 10 is welded through, the liquid cooling plate 10 and the base plate 100 will not be welded together, thereby avoiding the liquid cooling plate 10 and the base plate 100 from being welded together, ensuring the normal processing flow of the liquid cooling plate 10, and at the same time, a clamping mechanism 200 is used to press the liquid cooling plate 10 against the base plate 100, which can ensure the welding strength of the liquid cooling plate 10 and ensure the sealing performance meets the requirements.

[0037] It should be noted that the clamping mechanism 200 can be a quick clamp, and the number of the clamping mechanisms 200 can be multiple. Specifically, in the present embodiment, the number of the clamping mechanisms 200 can be fourteen, and the base plate 100 is a rectangular plate structure as a whole, wherein five clamping mechanisms 200 are respectively provided on the two long sides of the base plate 100, and two clamping mechanisms 200 are respectively provided on the two short sides of the base plate 100.

[0038] It should be noted that the liquid cooling plate 10 may include two stacked aluminum plates, and the welding periphery of the liquid cooling plate 10 is a rectangular periphery. Therefore, in this embodiment, the welding reserved groove 101 is an annular groove. Specifically, the welding reserved groove 101 is a rectangular groove (such as Figure 5 As shown), to correspond to the shape of the welding periphery of the liquid cooling plate 10.

[0039] In this way, during the welding process of the periphery of the liquid cooling plate 10, even if the liquid cooling plate 10 is welded through, the laser will be shot into the welding reserved groove, which will not cause the liquid cooling plate 10 and the base plate 100 to be welded together, thereby avoiding the liquid cooling plate 10 and the base plate 100 from being welded together and ensuring the normal processing flow of the liquid cooling plate 10.

[0040] In order to facilitate the pressing of the liquid cooling plate 10, the welding tool also includes a liquid cooling plate 10 pressing plate, which is used to press the liquid cooling plate 10 on the base plate 100. The pressing mechanism 200 is used to press the liquid cooling plate 10 pressing plate so that the liquid cooling plate 10 pressing plate presses the liquid cooling plate 10 onto the base plate 100.

[0041] Among them, the pressure plate of the liquid cooling plate 10 is provided with a peripheral welding seam 501, and the peripheral welding seam 501 is used to expose the welding periphery of the liquid cooling plate 10 to facilitate laser welding by welding equipment. It can be understood that the peripheral welding seam 501 is equivalent to a rectangular annular through hole.

[0042] Specifically, the pressure plate of the liquid cooling plate 10 includes a first pressure plate 510, a second pressure plate 520, a third pressure plate 530, a fourth pressure plate 540, a fifth pressure plate 560 and a connecting plate 550. The first pressure plate 510 and the third pressure plate 530 are respectively arranged on the two long sides of the base plate 100, the second pressure plate 520 and the fourth pressure plate 540 are respectively arranged on the two short sides of the base plate 100, the fifth pressure plate 560 is located between the first pressure plate 510 and the third pressure plate 530, and both are spaced apart from the first pressure plate 510 and the third pressure plate 530. At the same time, the fifth pressure plate 560 is located between the second pressure plate 520 and the fourth pressure plate 540, and both are spaced apart from the second pressure plate 520 and the fourth pressure plate 540.

[0043] It is easy to understand that the gaps between the fifth pressure plate 560 and the first pressure plate 510 , the fifth pressure plate 560 and the second pressure plate 520 , the fifth pressure plate 560 and the third pressure plate 530 , and the fifth pressure plate 560 and the fourth pressure plate 540 together constitute the peripheral welding seam 501 .

[0044] There are two connecting plates 550 , and the connecting plates 550 can be connected to the first pressing plate 510 and the fifth pressing plate 560 at the same time, or the connecting plates 550 can also be connected to the third pressing plate 530 and the fifth pressing plate 560 at the same time.

[0045] For example, when welding the welding periphery of the liquid cooling plate 10 , when the laser device welds part of the welding periphery of the liquid cooling plate 10 through the gap between the first pressure plate 510 and the fifth pressure plate 560 , the connecting plate 550 may also choose to connect the third pressure plate 530 and the fifth pressure plate 560 at the same time.

[0046] Among them, two clamping mechanisms 200 located on one of the short sides of the base plate 100 clamp the second clamping plate 520, and two clamping mechanisms 200 located on the other short side of the base plate 100 clamp the fourth clamping plate 540. The clamping mechanism 200 has a clamping rod 210. Among the five clamping mechanisms 200 located on one of the long sides (which can be understood as the first long side) of the base plate 100, the lengths of the clamping rods 210 of the five clamping mechanisms 200 are not the same. The clamping mechanism 200 with three long clamping rods 210 clamps the fifth clamping plate 560, and the clamping mechanism 200 with two short clamping rods 210 clamps the third clamping plate 530.

[0047] Among the five clamping mechanisms 200 located on the other long side (which can be understood as the second long side) of the base plate 100, the lengths of the clamping rods 210 of the five clamping mechanisms 200 are also not the same. The clamping mechanism 200 with only two short clamping rods 210 presses the first pressure plate 510, while the clamping mechanism 200 with three long clamping rods 210 does not press on the fifth pressure plate 560.

[0048] Alternatively, when the laser device welds a portion of the welding periphery of the liquid cooling plate 10 through the gap between the third pressing plate 530 and the fifth pressing plate 560 , the connecting plate 550 may also selectively connect the first pressing plate 510 and the fifth pressing plate 560 at the same time.

[0049] Among them, the two clamping mechanisms 200 located on one of the short sides of the base plate 100 clamp the second clamping plate 520, the two clamping mechanisms 200 located on the other short side of the base plate 100 clamp the fourth clamping plate 540, and among the five clamping mechanisms 200 located on the first long side of the base plate 100, the clamping mechanism 200 with three long clamping rods 210 does not press on the fifth clamping plate 560, and the clamping mechanism 200 with two short clamping rods 210 clamps the third clamping plate 530.

[0050] Among the five clamping mechanisms 200 located on the second long side of the base plate 100 , the lengths of the clamping rods 210 of the five clamping mechanisms 200 are also different. The clamping mechanism 200 with two short clamping rods 210 clamps the first clamping plate 510 , and the clamping mechanism 200 with three long clamping rods 210 clamps the fifth clamping plate 560 .

[0051] Please refer to Figure 3 and Figure 4In order to facilitate welding the faucet 20 to the aluminum plate, the welding tool also includes a limiting column 300. The limiting column 300 is arranged on the base plate 100. The limiting column 300 is used to cooperate in the faucet 20 to limit the faucet 20. In addition, in order to facilitate the removal of the limiting column 300, in this embodiment, the limiting column 300 and the base plate 100 are threadedly matched.

[0052] It can be understood that the limiting column 300 can be a cylindrical structure.

[0053] In addition, the welding tool also includes a faucet pressure plate 400, which is provided with a welding through hole 401, and the limiting column 300 is passed through the welding through hole 401. The faucet pressure plate 400 is used to press the faucet 20 to the welding plate 30 (which can be understood as an aluminum plate).

[0054] Specifically, the faucet pressing plate 400 is a square plate, the welding through hole 401 is a circular through hole, and the welding through hole 401 is located in the middle of the faucet pressing plate 400 .

[0055] Among them, it is easy to understand that the faucet 20 includes a cylindrical structure 21 and a faucet welding plate body 22 connected to one end of the cylindrical structure 21, and the faucet welding plate body 22 is provided with a through hole connected to the cylindrical structure 21, and the faucet pressure plate 400 can press the faucet welding plate body 22 on the aluminum plate, and the welding is performed by exposing part of the structure of the faucet welding plate body 22, partially quickly clamping the faucet pressure plate 400, and partially quickly pressing the aluminum plate set on the base plate 100. The welding equipment welds the faucet welding plate body 22 and the aluminum plate through the welding through hole 401 to complete the welding process of the faucet 20.

[0056] It should be noted that the process of welding the water nozzle 20 can be completed first, and then the welding of the two layers of aluminum plates can be carried out. Among them, the base plate 100 is provided with an avoidance through hole 102, and the welding reserved groove 101 surrounds the annular groove. In this way, after the aluminum plate with the water nozzle 20 is welded is flipped one hundred and eighty degrees, the water nozzle 20 can be inserted into the avoidance through hole 102. At the same time, the limit column 300 is removed, and then another layer of aluminum plate is added, and then the liquid cooling plate 10 pressure plate is added, and the liquid cooling pressure plate 500 is quickly clamped to perform laser welding of the double-layer aluminum plate (i.e., welding the welding periphery of the liquid cooling plate 10).

[0057] To summarize, the welding tool includes a base plate 100 and a clamping mechanism 200. The base plate 100 is used to support the liquid cooling plate 10. The base plate 100 is provided with a welding reserved groove 101. The welding reserved groove 101 is used to be covered by the welding periphery of the liquid cooling plate 10. The clamping mechanism 200 is arranged on the base plate 100. The clamping mechanism 200 is used to press the liquid cooling plate 10 on the base plate 100.

[0058] Since the base plate 100 is provided with a welding reserved groove 101, when the welding periphery of the liquid cooling plate 10 is welded by laser welding, even if the liquid cooling plate 10 is welded through, the liquid cooling plate 10 and the base plate 100 will not be welded together, thereby avoiding the liquid cooling plate 10 and the base plate 100 from being welded together, ensuring the normal processing flow of the liquid cooling plate 10, and ensuring the welding penetration and product quality. At the same time, the clamping mechanism 200 is used to press the liquid cooling plate 10 on the base plate 100, which can ensure the welding strength of the liquid cooling plate 10 and ensure the sealing performance meets the requirements.

[0059] The clamping mechanism 200 uses a quick clamp to replace the manual pressing method to ensure the pressing strength. On the basis of the welding equipment remaining unchanged, the strength and airtightness of the product (such as the liquid cooling plate 10) after welding meet the requirements.

[0060] The welding tool is easy to operate and can quickly and effectively achieve the welding strength of the liquid cooling plate 10 . The welding tool can not only achieve the welding of the periphery of the liquid cooling plate 10 , but can also be used for the welding of the liquid cooling plate 10 and the water nozzle 20 at the same time.

[0061] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
