[0002] With the rapid development of new energy vehicles, power batteries, as the power source of new energy vehicles, are one of the key components of new energy vehicles.

[0003] Existing power batteries include a battery cover with an explosion-proof valve and a terminal pin assembly. The terminal pin assembly consists of pins, a plastic cover, a terminal, and a sealing ring. During assembly, the pins and the terminal are first welded together, followed by a sealing ring fitted over the free end of the terminal. Finally, the plastic cover is crimped together to form the terminal pin assembly. However, currently, only one set of terminals and pins can be welded at a time, and the welding cavity is single, resulting in high welding temperatures. This can easily cause deformation of the terminals and pins after welding, reducing efficiency and yield.

[0004] Therefore, there is an urgent need for a welding jig and a welding device to solve the above technical problems. Utility Model Content

[0033] Please refer to the attached Figure 1 To the attached Figure 3 The invention introduces a welding jig and a welding device provided by the utility model.

[0034] It should be noted that the welding jig in this embodiment is used to weld the pole 610 and the pin 620. That is, the pole 610 and the pin 620 are combined to form the assembly to be welded 600 in this embodiment. Of course, in other embodiments, other similar structures can also be welded, which is not specifically limited here.

[0035] Please refer to Figures 1 to 3 This embodiment provides a welding jig, which is used to weld the component to be welded 600. The component to be welded 600 includes a pole 610 and a pin 620 that are limitedly connected. The welding jig includes a base 100 and a clamping member 200, wherein the working plane 110 of the base 100 is provided with a plurality of grooves 101 arranged at intervals, and the grooves 101 are used to load the component to be welded 600 to limit the position of the component to be welded 600; the clamping member 200 is movably arranged on the top of the base 100, and the clamping member 200 can press the component to be welded 600 into the groove 101.

[0036] In the welding jig of this embodiment, when welding the pole 610 and the pin 620, the assembled pole 610 and the pin 620 are placed in the groove 101. The groove wall of the groove 101 will be limited by the outer periphery of the component to be welded 600. Then, the component to be welded 600 is pressed by the clamping member 200, so that the component to be welded 600 is limited in all directions, thereby preventing the problem of shaking or welding failure during welding, thereby improving the yield rate. In addition, multiple grooves 101 are set at intervals on the base 100, so that the welding jig can simultaneously weld the component to be welded 600 composed of multiple poles 610 and multiple pins 620, thereby improving welding efficiency. At the same time, the spacing between the grooves 101 also ensures that the components to be welded 600 do not contact each other, so that they will not affect each other.

[0037] Please refer to Figure 1 and Figure 2Specifically, a mounting hole 102 is provided at the bottom of the groove 101, and the mounting hole 102 is used to accommodate at least part of the pole 610, and the groove 101 is used to accommodate the pin 620 and other parts of the pole 610, so as to achieve double limitation of the pin 620 and the pole 610 to ensure their accurate positioning and avoid large deviations in the welding position and cause poor welding problems.

[0038] Optionally, the shape of the groove 101 is at least the same as the shape of the portion of the pin 620 to be welded, so as to accommodate the pin 620 and limit the pin 620 .

[0039] Optionally, the shape of the groove 101 is square, which is adapted to the shapes of the parts to be welded of various pins 620, thereby improving the adaptability of the welding jig.

[0040] Specifically, the working plane 110 of the base body 100 is also provided with an air avoidance groove 103, which passes through a side wall of the base body 100. The air avoidance groove 103 is connected to the groove 101, that is, a step groove is formed, so that one end of the component to be welded 600 placed in the groove 101 extends out of the groove 101 and is located on the step groove, so that after the welding of the pole 610 and the pin 620 is completed, the operator can remove the component to be welded 600 through the air avoidance groove 103, which is more convenient for taking the component to be welded 600.

[0041] In some embodiments, the clamping member 200 is provided with a plurality of avoidance holes 210 , which are arranged one-to-one corresponding to the grooves 101 , so that when an external welding part welds the assembly to be welded 600 , it can pass through the clamping member 200 to avoid being blocked by the clamping member 200 .

[0042] Optionally, the coverage area of the avoidance hole 210 is larger than the area of the welding area of the component to be welded 600, so as to avoid the welding area of the component to be welded 600, effectively exposing the welding area of the component to be welded 600, thereby facilitating welding of the welding area by external welding parts.

[0043] Optionally, the shape of the avoidance hole 210 is the same as the shape of the welding area of the component to be welded 600, so that the avoidance hole 210 is more suitable for avoiding the welding area. For example, in this embodiment, the welding area formed by the terminal 610 and the pin 620 is circular, so the shape of the avoidance hole 210 is circular.

[0044] Optionally, the diameter of the avoidance hole 210 gradually decreases from the side away from the base body 100 to the side toward the base body 100 , thereby making it easier for the welding head of the welding part to extend into the welding part.

[0045] Please refer to Figure 1 and Figure 3In some embodiments, one side of the clamping member 200 is connected to a driving member 300, and the driving member 300 is arranged on one side of the base body 100. The driving member 300 is used to drive the clamping member 200 to move in a vertical direction to clamp or loosen the component to be welded 600, thereby realizing the driving of the movement of the clamping member 200, so that the operator can quickly load the component to be welded 600.

[0046] Optionally, the driving member 300 is a cylinder or a linear motor, both of which can drive the pressing member 200 .

[0047] In some embodiments, the pressing member 200 further includes a mounting seat, which is disposed on one side of the base body 100 and is used to mount the driving member 300 .

[0048] In some embodiments, the welding jig also includes a base 400, and the base body 100 is spaced apart on the base 400. The base 400 is used to connect to an external structure, that is, the entire welding jig is installed on an external welding part to facilitate welding of the component to be welded 600 on the welding jig. The base body 100 and the base 400 are spaced apart, so that vibration or other problems of the external welding part itself will not be transmitted to the component to be welded 600, thereby improving the effectiveness of welding.

[0049] It is understandable that the mounting seat is provided on the base 400 so that the mounting seat is fixed and stable, thereby improving the installation stability of the driving member 300 and the pressing member 200 .

[0050] In some embodiments, a support member 500 is further provided between the seat body 100 and the base 400 so that the seat body 100 and the base 400 are spaced apart.

[0051] It can be understood that corresponding assembly holes are provided on the base 400, the support member 500, the mounting seat and the base body 100, which are assembled by bolts to realize the external connection of the base 400, the connection between the base 400 and the support member 500, the connection between the base 400 and the mounting seat, and the connection between the support member 500 and the base body 100, thereby improving the stability of the welding jig.

[0052] This embodiment also provides a welding device, which includes the welding jig described in any of the above solutions. By adopting the above welding jig, the yield rate and welding efficiency of the welding device when welding the pole 610 and the pin 620 can be improved.

[0053] In some embodiments, the welding device further includes a welding part, and the welding jig is detachably connected to the working surface of the welding part, thereby enabling the welding of the welding part to the assembly 600 to be welded.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
