Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] At present, when welding the explosion-proof sheet to the battery cover, the battery cover is usually placed on a welding platform, the explosion-proof sheet is inserted into the explosion-proof sheet mounting hole on the battery cover, and then the explosion-proof sheet and the battery cover are welded by welding equipment to complete the assembly of the two.

[0034] However, during welding, high temperatures are generated, causing the battery cover to deform due to heat, resulting in positional displacement of the battery cover, which can easily lead to poor welding problems, resulting in reduced welding quality and low product yield after welding.

[0035] Therefore, in order to improve the welding quality and increase the product yield after welding, this embodiment provides an explosion-proof plate welding tool for welding the explosion-proof plate and the battery cover plate, and the battery cover plate is provided with an installation through hole for placing the explosion-proof plate.

[0036] like Figures 1 to 4 As shown, the explosion-proof plate welding tooling includes a carrying platform 1 and a pressing assembly 2. The carrying platform 1 is provided with a placement groove 11 and an avoidance gap 12 connected to the placement groove 11. The battery cover 200 is accommodated in the placement groove 11. The pressing assembly 2 includes a pressing member 21 and a driving member 22. The pressing member 21 is arranged above the carrying platform 1 and is connected to the driving member 22. The driving member 22 is used to drive the pressing member 21 to move closer to or away from the carrying platform 1. The pressing member 21 is also provided with a welding through hole 211 corresponding to the explosion-proof plate 100.

[0037] By providing a placement groove 11 on the carrying platform 1, after the battery cover 200 is placed in the placement groove 11, the placement groove 11 can limit and fix the battery cover 200 to avoid the battery cover 200 from being displaced and causing inaccurate position, and by providing a pressing member 21 above the carrying platform 1 that can approach or move away from the carrying platform 1 under the action of a driving member 22, when the explosion-proof plate 100 and the battery cover 200 are welded through the welding through hole 211 of the pressing member 21, the driving member 22 can be used to drive the pressing member 21 to press the battery cover 200. On the one hand, the fixation of the battery cover 200 is further improved to avoid position deviation. On the other hand, by applying pressure to the battery cover 200, the stress generated in the battery cover 200 due to high temperature during welding is offset to prevent the battery cover 200 from being deformed, thereby improving the welding quality and the product yield after welding.

[0038] The driving member 22 can be freely selected according to the on-site environment and cost budget, for example, a hydraulic cylinder, an electric cylinder or a pneumatic cylinder, etc. In this embodiment, a pneumatic cylinder is used as the driving member 22 to drive the pressing member 21 to move closer to or away from the supporting platform 1. It has a simple structure, easy installation and maintenance, fast response speed, low cost, and relatively small output, which avoids large pressure from damaging the battery cover 200.

[0039] Alternatively, if Figure 3 As shown, a vent hole 13 is provided in the placement groove 11 and is arranged opposite to the installation through hole and passes through the carrying platform 1. By providing the vent hole 13 passing through the carrying platform 1 in the avoidance sink 14, air circulation during welding is ensured, thereby improving welding quality.

[0040] Optionally, the placement groove 11 is further provided with an avoidance sink 14 arranged opposite to the installation through hole, and the vent 13 is opened in the avoidance sink 14. By opening the avoidance sink 14 arranged opposite to the installation through hole on the battery cover 200 on the placement groove 11, and opening the vent 13 in the avoidance sink 14, the vent 13 is prevented from being blocked when the battery cover 200 is placed in the placement groove 11, and ventilation space is reserved for the vent 13.

[0041] Alternatively, if Figure 4As shown, the pressing member 21 includes an abutting portion 212 and a connecting portion 213. The abutting portion 212 is used to abut against the battery cover 200 and is provided with a welding through hole 211. The connecting portion 213 is connected to the output end of the driving member 22, and the thickness of the connecting portion 213 is greater than the thickness of the abutting portion 212. By using a portion with a larger thickness as the connecting portion 213, the structural stability of the connection between the driving member 22 and the connecting portion 213 is better, and by using a portion with a smaller thickness as the abutting portion 212, it is ensured that the abutting portion 212 will not apply excessive pressure to the battery cover 200, resulting in damage to the battery cover 200.

[0042] Alternatively, if Figure 4 As shown, the pressing assembly 2 further includes a connecting member 23, which is used to connect the connecting portion 213 and the driving member 22. By using the connecting member 23 to connect the connecting portion 213 and the driving member 22, the two are detachably connected, so that when pressing battery covers 200 of different specifications and models, different pressing members 21 can be connected to the driving member 22.

[0043] Specifically, the connecting member 23 is a bolt, a connecting through hole is provided on the connecting portion 213, a connecting threaded hole corresponding to the connecting through hole is provided on the driving member 22, and one end of the connecting member 23 passes through the connecting through hole and is threadedly connected to the connecting threaded hole. The connecting portion 213 and the driving member 22 are connected by bolts, and the structure is simple and easy to disassemble and assemble.

[0044] Optionally, the connecting portion 213 and the abutting portion 212 are integrally formed. By adopting the integral forming, it is ensured that the pressing member 21 formed by the connecting portion 213 and the abutting portion 212 has a high structural strength.

[0045] Optionally, the area of ​​the bursting disk 100 is smaller than two-thirds of the area of ​​the welding through hole 211. By making the area of ​​the bursting disk 100 smaller than two-thirds of the area of ​​the welding through hole 211, the welding through hole 211 provides sufficient operating space for welding operations to avoid interference.

[0046] Optionally, the welding through hole 211 is polygonal, circular or elliptical. The shape of the welding through hole 211 can be freely set according to demand, as long as the area of ​​the welding through hole 211 is sufficient. In this embodiment, the welding through hole 211 is elliptical.

[0047] Alternatively, if Figure 3 As shown, the carrying platform 1 is provided with a plurality of avoidance notches 12 connected to the placement groove 11. By providing a plurality of avoidance notches 12 on the carrying platform 1, it is convenient to store and retrieve the battery cover 200 on the carrying platform 1, wherein the number of avoidance notches 12 can be freely set according to demand. In this embodiment, two avoidance notches 12 are provided on both sides of the carrying platform 1 along the width direction.

[0048] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
