Therefore, a soldering positioning fixture was designed to ensure the soldering quality and consistency of the SMD antenna.
[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a welding positioning fixture.
[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a welding positioning fixture for welding and positioning a patch antenna. The patch antenna includes a body, one end of which has a chamfer, and the other end of which has two welding positions. The fixture includes a mounting base plate, on which a positioning seat that can move left and right is provided. The upper end of the positioning seat has a slot along the front-back direction for placing the patch antenna. A fixing block is provided at the front end of the slot, and a top block that can move back and forth is provided at the rear end of the slot. In this solution, the slot is used to place the patch antenna, the fixing block is used to hold one end of the patch antenna, and the top block is used to hold the other end of the patch antenna, thereby achieving clamping and positioning.
[0006] Furthermore, the fixing block consists of a card plate and a card holder, which are arranged perpendicularly. The card plate is engaged with the front end slot of the card groove, and the contact surface between the card plate and the patch antenna has an inward folding structure corresponding to the chamfer. The card holder is located on the front side of the positioning seat. In this solution, the inward folding structure can better position the product and improve positioning accuracy.
[0007] Furthermore, the top block consists of a top plate and a connecting plate, which are arranged perpendicularly. The top plate is engaged with the rear end slot of the card slot, and the connecting plate is located behind the positioning seat. In this design, the top plate is used to hold the patch antenna in place, and the connecting plate is used to connect with the transmission component, facilitating the adjustment of the front and rear position of the top plate by the transmission component via the connecting plate, thus simplifying operation.
[0008] Furthermore, the top block is fixedly connected to a pull rod, which is horizontally movable back and forth on the positioning seat in the front-to-back direction. In this design, the top block clamps and releases the patch antenna by moving the pull rod back and forth in the front-to-back direction.
[0009] Furthermore, a mounting plate is provided at the front end of the positioning seat, and the pull rod passes through the body of the positioning seat and the mounting plate. A baffle is fixed at the front end of the pull rod, and a compression spring is provided between the baffle and the mounting plate.

[0012] Furthermore, both the first and second mounting bases are provided with threaded holes, and the outer surfaces of both the first and second limiting members are provided with external threads corresponding to the threaded holes. The first limiting member and the first mounting base are connected in an adjustable threaded manner, and the second limiting member and the second mounting base are connected in an adjustable threaded manner. In this solution, the adjustable connection between the limiting member and the mounting base facilitates the setting of different endpoints of the positioning seat in the left-right direction, meeting more welding position requirements.
[0013] Furthermore, a groove is formed downwards in the middle of the slot, and the groove is perpendicular to the slot. In this design, the groove facilitates product removal and can also collect impurities generated during welding.
[0014] Furthermore, the card holder is detachably fixed to the positioning seat by bolts. In this design, fasteners are used for connection, ensuring a secure installation and facilitating disassembly.
[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:
