Description

Technical Field

[0001] The utility model relates to the field of coil production jigs, in particular to a hollow coil positioning and assembly jig. Background Art

[0002] During the coil production process, the PCB board and the air-core coil need to be assembled and bonded together. The traditional method is to manually place the prepared air-core coil and the PCB board with the permanent magnet soldered on it tightly together, squeezing and bonding them one by one. However, assembling the air-core coil and PCB board using this method is not only inefficient but also very difficult. The manual assembly process not only causes the connected air-core coil and PCB board to be misaligned, but also damages the air-core coil, resulting in a high defective rate. Furthermore, the labor intensity is high and the labor cost is high. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a hollow coil positioning and assembly jig.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A hollow coil positioning and assembly jig includes a jig base and a jig pressure plate that cooperates with the jig base to extrude the hollow coil. The jig base includes a base body, an hollow coil pressure platform located inside the base body and integrally formed with the base body, wire foot reserved grooves located on both sides of the hollow coil pressure platform and running through the base body, a plurality of grooves arranged on the hollow coil pressure platform for placing coil gaskets, and a plurality of pressure plate pin slots opened on both sides of the base body and connected to the wire foot reserved grooves.

[0006] Preferably, positioning holes are provided at both ends and the middle portion of the base body.

[0007] Preferably, there are four grooves on the air-core coil pressure platform for placing coil gaskets, which are equidistantly arranged and have the same depth.

[0008] Preferably, four pressure plate pin slots connected to the line foot reserved slots are equidistantly arranged on both sides of the base body.

[0009] Preferably, the jig pressure plate includes a pressure plate body, a plurality of positioning pins integrally formed below both sides of the pressure plate body and corresponding to the pressure plate pin grooves, and an arc groove provided on the lower end surface of the pressure plate body and in full contact with the air-core coil.

[0010] The beneficial effects of the present invention are as follows: the jig significantly improves assembly efficiency, precision and stability through the design of precise positioning holes, equidistant grooves, pressure plate pin slots and arc-shaped slots. In addition, the jig can process multiple air-core coils at the same time and ensure high consistency and low offset during the assembly process, thereby enhancing the compatibility and flexibility of the jig and improving the overall production quality.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0016] Example

[0017] A hollow coil positioning assembly fixture, such as Figure 1-4 As shown, it includes a jig base 1 and a jig pressing plate 2 that cooperates with the jig base 1 to extrude the air-core coil.

[0018] The jig base 1 includes a base body 11, an air-core coil pressure platform 12 located inside the base body 11 and integrally formed with the base body 11, wire foot reserved grooves 13 located on both sides of the air-core coil pressure platform 12 and passing through the base body 11, a plurality of grooves 14 arranged on the air-core coil pressure platform 12 for placing coil gaskets, and a plurality of pressure plate pin grooves 15 opened on both sides of the base body 11 and connected to the wire foot reserved grooves 13.

[0019] Positioning holes 11 are provided at both ends and the middle of the base body 11. Specifically, after the base body 11 is placed, it can be fixed in place through the positioning holes 11 in conjunction with positioning columns or bolts, which can improve the assembly efficiency and assembly quality of the air-core coil.

[0020] The jig pressing plate 2 includes a pressing plate body 21, a plurality of positioning pins 22 integrally formed on the lower sides of the pressing plate body 21 and corresponding to the pressing plate pin grooves 15, and an arc groove 23 provided on the lower end surface of the pressing plate body 21 and in full contact with the air-core coil. Specifically, the jig pressing plate 2 utilizes the arc groove 23 to cover the upper end of the air-core coil, which is beneficial to improving the positioning of the air-core coil and preventing it from deviating during assembly.

[0021] In this embodiment, four grooves 14 for placing coil gaskets are equidistantly arranged on the air-core coil pressure platform 12 , and the depths of the four grooves 14 are consistent, so as to facilitate the extrusion assembly of four air-core coils at the same time.

[0022] In this embodiment, there are four pressure plate pin slots 15 equidistantly arranged on both sides of the base body 11 that are connected to the wire pin reserved slots 13. Specifically, the pressure plate pin slots 15 are assembled with the positioning pins 22 of the jig pressure plate 2, which is beneficial for positioning the jig pressure plate 2 and aligning it to extrude the air-core coil for assembly.
