[0002] In electronic devices, such as speakers, inductors, transformers, etc., coil winding is a key manufacturing process. The wire is wound through a wire rack, which serves to connect the coil to an external power source, similar to the positive and negative poles of a battery. Through the rotation of the shaft and the assistance of rollers, the wire can be wound in a predetermined direction and density to form the desired coil shape.

[0003] The patent application number 201210186057.6 discloses a coil winding machine, which can realize vertical winding of various flat copper wires with good tightness and no damage to the insulation layer. The size can also be adjusted according to different needs to meet the process requirements, with small fixed investment, short production time and reduced production costs. In combination with the above application and in comparison with the prior art, during the use of the lead frame, when the diameter of the wound wire is different, the wire is prone to shaking and deviating during the winding process using the lead frame, which affects the winding effect and the density of the wire after winding, thereby affecting the practicability of the existing lead frame. For this reason, we propose a lead frame for coil winding. Utility Model Content

[0004] The purpose of the utility model is to provide a wire rack for coil winding, so as to solve the problem that in the use of the existing wire rack proposed in the above background technology, when the diameters of the wound wires are different, the wires are easy to shake and deviate during the winding process using the wire rack, which not only affects the winding effect, but also affects the density of the wire after winding, thereby affecting the practicality of the existing wire rack.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire rack for coil winding, comprising a wire conveying rack, the wire conveying rack is provided with a wire passing rack, the wire passing rack comprises an incoming wire limiting assembly, a wire passing limiting assembly and an outgoing wire limiting assembly, tensioning shafts are symmetrically installed at both ends of the inner side of the wire conveying rack, a rotating sleeve is installed on the tensioning shaft, a wire wheel group is installed on the rotating sleeve, a ring fixing seat is installed on one side of the wire wheel group, and a hexagon socket bolt is installed on the ring fixing seat.

[0006] Preferably, the guide wheel assembly and the ring fixing seat are slidably mounted on the rotating shaft sleeve, and the guide wheel assembly and the rotating shaft sleeve are fixed by means of hexagon socket bolts.

[0007] Preferably, the wire-crossing limit assembly is installed at the inner center of the wire conveying frame, the wire-in limit assembly is installed at one inner end of the wire conveying frame, and the wire-out limit assembly is installed at the other inner end of the wire conveying frame.

[0008] Preferably, the in-line limiting assembly, the over-line limiting assembly and the out-line limiting assembly are each provided with two symmetrical vertical poles, and stop rings are installed at the ends of the two vertical poles.

[0009] Preferably, tensioning rings are installed at both ends of the tensioning shaft, and tensioning limit grooves are opened on both sides of the wire conveying frame, a lifting sleeve is installed on the outer side of the tensioning limit groove and the wire conveying frame, a lifting limit rod is arranged on the inner side of the lifting sleeve, and a tensioning spring is installed on the lifting limit rod.

[0010] Preferably, both ends of the tensioning shaft rod pass through the tensioning limit grooves and are installed through the tensioning ring sleeve and the lifting limit rod sleeve, and the tensioning spring is arranged at the bottom of the tensioning ring sleeve.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) By setting the wire wheel group, when the device is used to wind the wire, the wire wheel group is set to be movable and adjustable. When winding, if wires of different sizes are wound, the distance between the two wire wheel groups can be adjusted according to the diameter of the wire, so that the wire is always kept at the center of the guide wheel during winding, avoiding the density being affected during the winding process, thereby better winding and use. At the same time, the wire is limited by the set limit component during winding, avoiding the wire from running off during winding, further improving the practicality of the device;

[0013] (2) In addition, during the winding process, since the wire is pulled, if the tension changes or the tightness of the wire is different, the winding effect will be affected. By setting a tension structure at both ends of the tensioning shaft rod for installing the wire wheel assembly in the device, during the winding process, if the tension of the wire changes, the two ends of the tensioning shaft rod will perform corresponding limit compensation in the tensioning limit groove, so as to better ensure the tension of the wire during the winding process and avoid affecting the winding density, thereby improving the practicality of the device.

The coil is widely used in various electronic devices. , such as generators, transformers, electromagnets, inductors, etc. The design of the wire rack makes the winding process simpler. The operator only needs to control the rotation of the shaft to realize the winding of the wire. By accurately controlling the rotation of the shaft and the position of the roller, high-precision winding can be achieved to ensure that the number of turns and shape of the coil meet the requirements. When the wire rack in the application is used to wind the coil, before the winding work, the wire is passed through one end of the wire conveying frame 100, the wire first passes through the outgoing wire limiting component 103, then passes through the wire wheel group 200 at one end, and continues to pass through the wire limiting component 102, and then passes through the wire wheel group 200 at the other end, and finally the wire passes through the incoming wire limiting component 101.

[0021] Specifically, the wire wheel assembly 200 and the ring fixing seat 202 are slidably installed on the rotating shaft sleeve 204, and the wire wheel assembly 200 and the rotating shaft sleeve 204 are fixed by the hexagon socket bolt 203 to ensure the stable installation of the wire wheel assembly 200, the wire-passing limit assembly 102 is installed at the inner center of the wire conveying frame 100, the incoming wire limit assembly 101 is installed at one end of the inner side of the wire conveying frame 100, and the outgoing wire limit assembly 103 is installed at the other end of the inner side of the wire conveying frame 100. Two symmetrical vertical poles are arranged on the incoming wire limit assembly 101, the over-the-wire limit assembly 102 and the outgoing wire limit assembly 103. The symmetrical vertical poles are used to prevent the wire from running off when winding the wire, and the ends of the two vertical poles are installed with stop rings 121, which is better After guiding the wire and passing through the wire, before the winding work, the distance between the two wire wheel assemblies 200 installed on the tensioning shaft 205 can be adjusted according to the diameter of the wire. When adjusting, loosen the hexagon socket bolt 203 on the ring fixing seat 202, and then slide the wire wheel assembly 200 on the rotating sleeve 204.

During winding, the wire wheel assembly 200 and the rotating sleeve 204 rotate on the tensioning shaft 205. The wire wheel assembly 200 is adapted to the winding of wires of different sizes, which can achieve better winding, avoid wire deviation during the winding process, and ensure the winding density.

[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a wire rack for coil winding, a tensioning ring 206 is installed at both ends of the tensioning shaft 205, and a through tensioning limit groove 201 is opened on both sides of the wire conveying frame 100, the outer side of the tensioning limit groove 201 is fixedly installed with a lifting sleeve 300 on the wire conveying frame 100, and the inner side of the lifting sleeve 300 is fixedly installed with a lifting limit rod 302, and a tensioning spring 301 is sleeved on the lifting limit rod 302. When the wire tension changes during winding, the tension structure set at both ends of the tensioning shaft 205 can be used to adjust the tension of the wire. When the wire is passed, both ends of the tensioning shaft 205 pass through the tensioning limit groove 201 and are installed on the lifting limit rod 302 through the tensioning ring sleeve 206. When the wire is passed, the tensioning ring sleeve 206 will generate a certain pressure to squeeze the tensioning spring 301 on the lifting limit rod 302. When the wire is wound, the tension changes, and the tensioning spring 301 is deformed at the same time and the force of the tensioning ring sleeve 206 changes, so that the tensioning ring sleeve 206 moves up and down on the lifting limit rod 302, providing a certain tension deformation, so as to better use the winding coil and avoid the loosening or breaking of the wire during winding, thereby improving the practicability of the device.

[0024] Specifically, the two ends of the tensioning shaft 205 pass through the tensioning limit groove 201, and are installed through the tensioning ring sleeve 206 and the lifting limit rod 302, so that the two ends of the tensioning shaft 205 can slide and rise and fall on the lifting limit rod 302. At the same time, the tensioning spring 301 is arranged at the bottom of the tensioning ring sleeve 206, so that the tension is better provided by the tensioning spring 301.
