Description

Technical Field

[0001] The present invention relates to the technical field of motor coil processing, and particularly to an automatic winding device for motor coil processing. Background Art

[0002] An electric motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Among them, a coil usually refers to a wire winding in a ring shape. The most common coil applications include: motors, inductors, transformers, and loop antennas, etc. A coil in a circuit refers to an inductor, which means that wires are wound one by one, and the wires are insulated from each other. The insulating tube can be hollow or can contain an iron core or a magnetic powder core, simply referred to as an inductor. Inductors can be further divided into fixed inductors and variable inductors. A fixed inductor coil is simply referred to as an inductor or a coil. During the production process of an electric motor, it is necessary to process the coil onto the motor rotor through a winding device.

[0003] Currently, in the prior art, the coil winding device needs to wind the coil onto the fins of the motor rotor. During the processing, most winding devices drive the coil to perform a circular motion to achieve winding. Since the lengths of motor rotors are not uniform, when the length of the motor rotor is relatively long, the circular motion of the winding device will cause large vacancies on both sides of the motor rotor when the coil is wound onto the motor rotor. The coil will be wound onto the rotor fins with a delay, resulting in the phenomenon that the coil winding is not firm and loose. Moreover, it cannot be fixed according to the thickness of the motor rotor, and the winding process will generate some vibrations, affecting the winding efficiency of the motor rotor. Therefore, the present invention proposes an automatic winding device for motor coil processing. Summary of the Invention

Detailed Implementation Manner

[0018] In order to be able to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0019] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0020] In the prior art, a winding device winds a coil onto the fins of a motor rotor. Affected by the thickness and length of the motor rotor, since the winding device drives the coil to perform a circular rotation movement to wind the coil onto the fins of the motor rotor, when the length of the motor rotor is too long, there will be a large gap on both sides of the rotor during winding processing. When driving the coil to rotate and wind, the coil will be delayed in winding onto the motor rotor, resulting in the coil not being tightly wound onto the motor rotor, and then the phenomenon of the coil becoming loose occurs. Moreover, when winding and processing motor rotors of different thicknesses, the fixing method is affected by the thickness of the motor rotor, and there will be vibrations during the coil winding process, and the vibration force will be transmitted to the motor rotor. If it is not firmly fixed, the motor rotor will fall off, thus delaying the efficiency of the winding processing.

[0021] Therefore, the purpose of the present invention is at least that the stator fixing mechanism 200 drives the turntable 202 to rotate. The rotation of the turntable 202 can push the two side pressing plates 215 to move horizontally to both sides, and the pressing plates 215 can support the center of the motor rotor to achieve a fixing effect. Moreover, the rotation of the turntable 202 can also push the four clamping plates 110 towards the two outer support plates 101, thereby driving the clamping plates 110 to move along the mounting bracket 208. By adjusting the distance between the two outer support plates 101, it is possible to clamp and fix motor rotors of different thicknesses, assist in subsequent coil winding processing, and effectively prevent the problem that the vibration force generated during coil winding causes the motor rotor to fall off. Among them, the coil winding mechanism 300 can drive the second hub 321 to move along the limit bracket 322. Since the circular motion is changed into an elliptical motion, compared with circular winding, elliptical winding can make the coil wind more conformably onto the fins of the motor rotor, thereby improving the accuracy of coil processing.

[0022] Example, according to Figures 1 - 12 , as Figure 1 shown, an automatic winding device for motor coil processing provided by an embodiment of the present invention includes an outer support member 100. A stator fixing mechanism 200 is installed on the outer support member 100. The stator fixing mechanism 200 can be adjusted according to the thickness of the stator when cooperating with the outer support member 100 to fix the stator. Coil winding mechanisms 300 are arranged on both sides of the stator fixing mechanism 200. The coil winding mechanism 300 includes a second hub 321. The coil winding mechanism 300 can drive the second hub 321 to perform limit winding along the fins of the stator during coil winding; as Figure 7 shown, the stator fixing mechanism 200 includes a first motor 201. The output shaft of the first motor 201 is fixedly connected to a turntable 202. A threaded rod 209 is fixedly connected to the center of the upper surface of the turntable 202. A lifting rod 210 is meshed and connected above the threaded rod 209; Specifically, starting the first motor 201 can drive the rotating disc 202 to rotate. The rotation of the rotating disc 202 provides driving force, which can drive the stator fixing mechanism 200 to firmly fix the motor rotor through the threaded rod 209 and the lifting rod 210. At the same time, in cooperation with the outer support member 100, it can also be adjusted and fixed according to the thickness of the motor rotor. It not only realizes the fixation of the motor rotor, but also can be adjusted according to the thickness of the motor rotor, making the winding device have better versatility, realizing the winding process of motor rotors with different thicknesses, and improving the working efficiency of the winding device.

[0023] As Figure 3 , Figure 5 , Figure 6 and Figure 8 shown, the outer support member 100 includes a bottom plate 102. Both ends of the upper surface of the bottom plate 102 are fixedly connected with outer support plates 101. One fixed rod 103 is fixedly connected to the outer surface of each of the two outer support plates 101. The upper ends of the two fixed rods 103 are fixedly connected with a connecting rod 104. A first hub 105 is installed in the middle of the connecting rod 104. Two mounting seats 106 are fixedly connected to the inner surface of each of the two outer support plates 101. There are four mounting seats 106 in total. A connecting plate 107 is rotatably installed in each mounting seat 106. One end of each connecting plate 107 is rotatably installed with a fixed seat 108. One side of each fixed seat 108 is fixedly connected with a first slider 109. A first limiting groove 111 is formed above and below each first slider 109. A clamping plate 110 is fixedly connected to the inner surface of each first slider 109. Transmission rods 225 are rotatably installed on both sides of the lower surface of the rotating disc 202. One end of the lower surface of each of the two transmission rods 225 is fixedly connected with a mounting rod 226. A limiting member 203 is rotatably installed on each mounting rod 226. A side movable plate 205 is fixedly connected to the outside of each limiting member 203. Mounting brackets 208 are fixedly connected to the inner sides of the two side movable plates 205. The first slider 109 is installed on the mounting bracket 208 through the first limiting groove 111. Four uniformly distributed limiting side plates 207 are fixedly connected to the surfaces of the two side movable plates 205. The limiting side plates 207 are located on both sides between the clamping plates 110. Expansion rods 204 are fixedly connected to the surfaces of the two side movable plates 205. Each expansion rod 204 is fixedly connected to the inner wall of the outer support plate 101; Specifically, when the turntable 202 rotates, since the transmission rods 225 are rotatably installed on both sides of the lower surface of the turntable 202, the mounting rods 226 at one end of the transmission rods 225 are installed in the limiting member 203, one side of the limiting member 203 is connected to the side movable plate 205, and the telescopic rods 204 are fixedly connected between the side movable plates 205 and the outer support plate 101. And since the mounting bracket 208 is fixedly connected to one side of the side movable plate 205, the side movable plate 205 and the mounting bracket 208 can be pushed to horizontally move along the telescopic rods 204 on both sides of the turntable 202. Since two first sliders 109 are installed on the mounting bracket 208, and the clamping plates 110 are fixedly connected to the inner surfaces of the first sliders 109, a fixed seat 108 is fixedly connected to one side of each first slider 109, a connecting plate 107 is rotatably installed in the fixed seat 108, one end of the connecting plate 107 is rotatably installed with a mounting seat 106, and the mounting seat 106 is fixedly connected to the inner wall of the outer support plate 101. When the mounting bracket 208 moves to both sides, it will also drive the first sliders 109 and the clamping plates 110 to move synchronously. And through the support of the connecting plate 107, the first sliders 109 and the clamping plates 110 can be pushed to move along the mounting bracket 208, so as to adjust the distance between the two clamping plates 110. Since the clamping plates 110 are arranged as arc-shaped pieces, the distance can be changed to clamp and fix motor rotors of different thicknesses. And since the limiting side plates 207 are fixedly connected to both ends of the two mounting brackets 208, the turntable 202 can also adjust the distance between the two limiting side plates 207. The coil can be limited through the limiting side plates 207, which is convenient for the coil to be wound around the motor rotor more quickly.

[0024] Such as Figure 7As shown, a barrel shaft 220 is arranged on the outer side of the lifting rod 220. Extension rods 222 are fixedly connected to both sides of the lower end of the barrel shaft 220. A second fixing rod 223 is fixedly connected to the lower end of each extension rod 222. Second limiting grooves 224 are arranged on both sides of the turntable 202. The second fixing rods 223 are located in the second limiting grooves 224. The second fixing rods 223 and the first motor 201 are fixedly connected to the upper surface of the bottom plate 102. Installation holes 206 are formed in both sides of the upper end of the barrel shaft 220. A first central shaft 213 is rotatably installed in each installation hole 206.

Connecting seats 214 are rotatably installed at the upper ends of the two L-shaped support sheet metals 212. A pressing plate 215 is fixedly connected to one side of each of the two connecting seats 214. The two pressing plates 215 are located on both sides of the barrel shaft 220. First sliding grooves 216 are arranged on the inner side surfaces of the two pressing plates 215. A first limiting block 217 is movably installed in the first sliding groove 216.

A rubber wheel 221 is fixedly connected to the output shaft of the second motor 219; Specifically, when the turntable 202 rotates, the threaded rod 209 on the upper surface of the turntable 202 will be driven to rotate. The threaded rod 209 is meshed with a lifting rod 210. The lifting rod 210 is located inside the cylinder shaft 220, and the lifting rod 210 can be driven to move up and down along the threaded rod 209 inside the cylinder shaft 220. Since an L-shaped support sheet metal 212 is rotatably installed in the first mounting groove 211 at the upper end of the lifting rod 210, the L-shaped support sheet metal 212 is installed in the mounting hole 206 of the cylinder shaft 220 through the first central shaft 213. The other end of the L-shaped support sheet metal 212 is rotatably installed with a connecting seat 214, and a pressing plate 215 is fixedly connected to one side of the connecting seat 214. When the lifting rod 210 rises, the pressing plate 215 can be pushed to both sides through the L-shaped support sheet metal 212. Moreover, since a first sliding groove 216 is provided on the inner side of the pressing plate 215, a first limiting block 217 is movably installed in the first sliding groove 216. One side of the first limiting block 217 is fixedly connected to a T-shaped telescopic rod 218, and the T-shaped telescopic rod 218 is fixedly connected to the upper part of the inner wall of the cylinder shaft 220. The pressing plate 215 can be pushed to move horizontally along the T-shaped telescopic rod 218 to both sides to support both sides of the motor rotor, realizing the fixation of the motor rotor. At the same time, since the central holes of the motor rotor have the same diameter, the rubber wheel 221 driven by the second motor 219 can drive the motor rotor to rotate. The rubber wheel 221 can be inserted into the central hole of the motor rotor and drive the motor rotor to rotate. And since two coil winding mechanisms 300 are provided, the winding process on both sides of the motor rotor can be carried out simultaneously, improving the winding efficiency.
