Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a PCB and wire harness welding jig used for hot pressing welding. Background Art

[0002] Hot compression welding is a welding process for connecting flexible circuit boards and rigid circuit boards. Hot compression welding uses heat and pressure to cause plastic deformation of the metal in the welding area, thereby pressing the metal wire and the metal welding area together, while destroying the oxide layer on the pressure welding interface, so that the atomic gravitational force range is reached between the pressure welded metal wire and the metal contact surface, thereby generating attraction between atoms and achieving the purpose of bonding; welding jigs are common in the electronics industry and are widely used in PCB welding. Their main function is to position and fix the integrated circuit board, thereby welding the components or wiring on the integrated circuit board.

[0003] In the prior art, when the wire harness and PCB are welded using a hot pressure welding solution, the hot pressure welding jig is placed on the track of the automated equipment, and the wire harness is positioned and fixed on the jig position corresponding to the PCB pad by a pressure strip; when the wire harness is too long and the jig is fixed on the automatic assembly equipment, employees can only operate on the track of the automated equipment when replacing the wire harness, which increases the difficulty of replacing the wire harness and easily causes the wire harness to be placed improperly, ultimately leading to abnormal welding. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a PCB and wiring harness welding jig for hot pressing welding, comprising: a welding jig and a fixing jig; the welding jig is detachably connected to the fixing jig;

[0006] The welding fixture comprises: a base and a connecting seat; the base is fixedly connected to the connecting seat, the bottom end surface of the base and the bottom end surface of the connecting seat are located in the same horizontal plane, and the height of the base is greater than the height of the connecting seat;

[0007] A plurality of first magnets are fixedly arranged inside the connecting seat; a plurality of second magnets and a plurality of third magnets are fixedly arranged inside the fixing fixture; the fixing fixture is placed on the connecting seat, and the axes of the plurality of first magnets are collinear with the axes of the plurality of second magnets, and the axes of the plurality of second magnets are collinear with the axes of the third magnets.

[0008] Furthermore, the fixing fixture includes: an upper cover and a lower cover; the upper cover and the lower cover are detachably connected.

[0009] Furthermore, the second magnets are fixedly provided at both ends of the upper cover in a vertical direction; and a plurality of first semicircular holes are provided in a horizontal direction at the middle portion of the upper cover.
