Description

Positioning jig for chip inductance welding mold Technical Field The utility model relates to the technical field of positioning of inductance coils, in particular to a positioning jig of a patch inductance welding die. Background An inductor is a component that can convert electric energy into magnetic energy and store it. In the working process, different magnetic fields can interfere with the magnetic field generated by the inductor and influence the function of the inductor, so that the inductor is magnetically shielded. The coil after winding can generate pins, the coil and the lead frame are welded later, so that the coil and the lead frame are integrated, powder pressing is carried out later, and when the existing welding work of the coil and the lead frame is carried out, the pins can shift, so that the contact points of the lead frame and the pins of the coil deviate. Disclosure of utility model The utility model aims to provide a positioning jig for a chip inductor welding die, aiming at overcoming the defects of the prior art. In order to achieve the above purpose, the technical scheme of the utility model is as follows: The utility model provides a paster inductance welding mould's location tool, includes the locating plate, and the locating plate is provided with a plurality of location stations, and the location station is including the reference column that supplies the coil snare to establish, and the locating seat has been arranged to the reference column periphery, and the locating seat shaping has the indent, to the lead wire groove of the pin location of coil, is provided with the welding hole of penetration shaping at the locating plate between locating seat and the reference column. Further, the number of the positioning seats is two, the two positioning seats are symmetrically arranged by taking the positioning column as a center, and the two positioning seats are arranged at intervals. Further, a gap between the positioning seat and the positioning seat is used for embedding a welding plate of the lead frame. Further, the positioning seat is provided with an adjusting structure for adjusting the position of the lead groove. Further, the adjusting structure comprises a transverse groove transversely formed in the positioning seat, the transverse groove is slidably provided with a sliding seat, the lead groove is formed in the sliding seat, and the sliding seat can transversely move in the transverse groove. Further, a first adjusting rod is arranged on one side of the sliding seat, a first adjusting hole for the first adjusting rod to pass through is transversely formed in the positioning seat, and the first adjusting rod is in transmission fit with the first adjusting hole. Further, a second adjusting rod is arranged on the other side of the sliding seat, a second adjusting hole for the second adjusting rod to pass through is transversely formed in the positioning seat, and the second adjusting rod is in transmission fit with the second adjusting hole.
