[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-4 The utility model provides a technical scheme that:

[0020] Referring to Figures 1-4 As shown, the resistance welding jig includes an electrode body 1, a product TO body 3, a product BASE 5, a positioning block body 4 mounted on the top of the electrode body 1, a product BASE 5 arranged on the positioning block body 4, a TO limiting sheet body 2 arranged between the electrode body 1 and the positioning block body 4, and a product TO body 3 arranged on the TO limiting sheet body 2. The top of the positioning block body 4 is fixedly mounted with the product BASE 5 and a BASE stopper 6.

[0021] The TO limiting sheet body 2 is put into the positioning block body 4, and the TO limiting sheet and the positioning block positioning point 12 are aligned and positioned with the TO limiting sheet clamping groove 9. Then, the positioning block body 4 is mounted on the electrode body 1 and fixed by the positioning block and electrode fixing hole 10. Nitrogen is connected to the nitrogen protection hole 8, and the BASE stopper 6 is fixed to the product switching positioning pin hole 7 product switching fixed pin. The jig assembly is completed, and during operation, only the product TO body 3 needs to be placed into the TO limiting sheet body 2 from above and contact the TO limiting sheet and product TO positioning point 11. Then, the product BASE 5 is placed into the BASE stopper 6 from above, and welding can be performed without thinking. The key points of resistance welding are compatible, foolproof, and improve operation efficiency and good products.

[0022] Referring to Figure 4 The inner wall of the TO limiting sheet body 2 is fixedly mounted with the TO limiting sheet and the product TO positioning point 11, and the circumferential outer wall of the TO limiting sheet body 2 is fixedly mounted with the TO limiting sheet and the positioning block positioning point 12.

[0023] By arranging the TO limiting sheet and the product TO positioning point 11 on the inner wall of the TO limiting sheet body 2, accurate positioning reference can be provided for the product. During resistance welding, it is ensured that the product is always in the correct position, avoiding poor welding due to position deviation. For example, in electronic component welding, accurate positioning can make the welding point accurately fall on the predetermined position, improving the stability of welding quality and circuit performance.

[0024] Referring to Figure 3 The top of the positioning block body 4 is provided with a TO limiting sheet clamping groove 9, and the two sides of the positioning block body 4 are respectively provided with a nitrogen protection hole 8 and a positioning block and electrode fixing hole 10.

[0025] The TO limiting sheet clamping groove 9 can accurately accommodate and fix the TO limiting sheet body 2, ensuring the position accuracy during resistance welding, which helps to realize accurate positioning of the welded product, improve the stability and consistency of the welding quality, for example, in electronic component welding, accurate positioning can ensure the accuracy of the welding point, avoiding problems such as virtual welding and short circuit.

[0026] Referring to Figure 3, a plurality of product switching positioning pin holes 7 are evenly opened on the positioning block body 4, which are matched with the BASE block 6. The plurality of product switching positioning pin holes 7 are arranged in a W shape.

[0027] The product switching positioning pin hole 7 is matched with the BASE block 6, which can provide accurate installation position for the BASE block 6, ensuring the position accuracy in the resistance welding jig. This helps to realize accurate positioning of the welded product, improve the stability and consistency of the welding quality. For example, in electronic component welding, accurate positioning can ensure the accuracy of the welding point, avoid problems such as virtual welding and short circuit.

[0028] Referring to Figures 1-2 , the BASE block 6 is L-shaped.

[0029] The L-shaped BASE block 6 can limit the product from two different directions. In the resistance welding process, it can effectively prevent the product from moving in the horizontal and vertical directions, ensuring that the product always stays in the correct welding position; for example, in electronic component welding, the L-shaped block can tightly hold the component to avoid displacement under the action of welding pressure.
