[0002] During the production and processing of mobile phones, the mobile phone motherboard bracket of the mobile phone needs to be welded with spring pieces, and the mobile phone motherboard bracket and the spring pieces are generally welded by spot welding, which requires the use of a mobile phone motherboard bracket spot welding fixture.

[0003] In the prior art, the authorized patent with announcement number CN216656927U discloses a mobile phone motherboard bracket spot welding jig, which has a lower bottom mold and an upper pressure plate, a bracket placement area is set on the upper surface of the lower bottom mold, and a bracket positioning column is set in the bracket placement area; the lower bottom mold is provided with a limiting profiling groove in the bracket placement area, and the lower surface of the lower bottom mold is provided with an air avoidance hole connected to the limiting profiling groove; the lower bottom mold is provided with at least two bottom mold mounting holes arranged at intervals, and each bottom mold mounting hole is respectively embedded with a bottom mold magnet; the upper pressure plate is respectively provided with a pressure plate mounting hole corresponding to each bottom mold mounting hole of the lower bottom mold, and each pressure plate mounting hole is respectively embedded with a pressure plate magnet; when the lower bottom mold and the upper pressure plate are closed, each bottom mold magnet is magnetically adsorbed with the corresponding pressure plate magnet. Through the above structural design, the utility model has the advantages of novel structural design and convenient use, and can effectively improve the spot welding efficiency of the mobile phone motherboard bracket and the spring.

[0004] However, when the above technical solution is actually used, the inventors found that there are still the following shortcomings: when the upper pressure plate and the lower bottom mold of the above-mentioned fixture are manually closed, the upper pressure plate and the lower bottom mold need to be manually aligned, and the magnetic adsorption will cause the upper pressure plate and the lower bottom mold to automatically adsorb when they are close to each other. In many cases, they are adsorbed together without being aligned, which requires them to be disassembled and then aligned and closed, which is very troublesome and affects the spot welding efficiency. In this regard, we propose a mobile phone motherboard bracket spot welding fixture to solve the above-mentioned problems. Utility Model Content
