Description

Technical Field

[0001] This utility model relates to the field of two-phase stepper motor stator winding technology, specifically an automatic winding machine for two-phase stepper motor stator windings. Background Technology

[0002] A two-phase stepper motor is a special type of electric motor consisting of a stator and a rotor. The stator of a two-phase stepper motor typically has 8 or 4 poles, each with a coil that can be energized in two directions. The rotor is composed of a ring magnet and iron cores at both ends. Small teeth are evenly distributed on the iron cores, and these teeth have a specific relative position to the teeth on the stator.

[0003] The working principle of a two-phase stepper motor is based on the interaction of magnetic fields. When the stator windings are energized in a specific sequence, a rotating magnetic field is generated, which attracts the rotor to rotate. By changing the direction and magnitude of the current in the windings, precise control of the rotor, including the direction and speed of rotation, can be achieved.

[0004] The stator is an important component of an electric motor. The rotor rotates through electromagnetic induction between the stator and the rotor. Copper wire for electromagnetic induction needs to be wound on the stator. Currently, the stators of two-phase stepper motors are mostly pre-formed. The winding equipment is located inside the stator to wind the wire. The pre-formed type is affected by the surrounding structure. During winding, the built-in winding equipment and the stator itself need to cooperate back and forth for winding displacement. The influence factors are large, the winding stability and efficiency are not high, and the winding quality is not high. Utility Model Content

[0005] The purpose of this invention is to provide an automatic winding machine for the stator winding of a two-phase stepper motor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The winding device includes a worktable, a winding assembly located on top of the worktable, and a winding auxiliary displacement guide assembly.

[0008] The winding assembly includes a lead-out assembly, a drive assembly, a winding support disk, and a winding rotating disk. The winding support disk is circular in shape and has a through hole in its center. The winding rotating disk is located inside the through hole. A placement slot for placing the stepper motor stator block is formed on one outer wall of the winding rotating disk. Slots are formed on the winding support disk on both sides of the winding rotating disk.

[0009] As a preferred embodiment of this utility model, the wire outlet assembly is located on the outer wall of the winding support disk on one side of the placement slot.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0024] Please see Figure 1-4This utility model provides a technical solution: an automatic winding machine for a two-phase stepper motor stator winding, including a stepper motor stator block 1 and a winding device 2 for winding the stepper motor stator block 1. The winding device 2 includes a worktable 21, a winding assembly 22 located on the top of the worktable 21, and a winding auxiliary displacement guide assembly 23. The winding assembly 22 includes a wire outlet assembly, a drive assembly, a winding support plate 221, and a winding rotary plate 222. The winding support plate 221 is circular in shape, with a through hole 2211 in the center. The winding rotary plate 222 is located inside the through hole 2211. A placement groove 2221 for placing the stepper motor stator block 1 is formed on one side of the outer wall of the winding rotary plate 222. The winding support plates 221 on both sides of the winding rotary plate 222 are also present. The device has a slot 2212. The wire outlet assembly is located on the outer wall of the winding support plate 221 on one side of the placement slot 2221. The wire outlet assembly includes a support plate 25 and a wire outlet guide tube 251 located on the support plate 25. The wire outlet guide tube 251 is parallel to the support plate 25. A wire outlet conical cap 252 is sleeved on the end of the wire outlet guide tube 251 near the stepper motor stator block 1. A winding copper wire is installed inside the wire outlet conical cap 252. One end of the winding copper wire is connected to the stepper motor stator block 1, and the other end passes through the wire outlet guide tube 251 and is connected to an external wire supply device. The drive assembly includes a drive motor 24. The drive motor 24 is located on the worktable 21 on the side of the winding support plate 221 away from the placement slot 2221. The output end of the drive motor 24 is connected to the middle part of the winding rotary disk 222 on the side away from the stepper motor stator block 1.

[0025] It should be noted that in this embodiment, the winding assembly 22 is located on the top of the workbench 21 and includes a wire output assembly, a drive assembly, a winding support plate 221 and a winding rotary plate 222. The wire output assembly consists of a support plate 25 and a wire output guide cylinder 251. The wire output guide cylinder 251 passes through the support plate 25 in parallel. A wire output conical cap 252 is sleeved on the end near the stepper motor stator block 1. The winding copper wire is passed through the inside. The wire output conical cap 252 guides the copper wire to prevent the copper wire from bending and ensures the uniformity and aesthetics of the winding.

[0026] The output end of the drive motor 24 is connected to the middle of the side of the winding support disk 221 away from the stepper motor stator block 1, driving the winding rotating disk 222 to rotate. The winding rotating disk 222 is located inside the through hole 2211 of the winding support disk 221. The two work together to realize the rotation and winding of the stepper motor stator block. When the winding support disk 221 rotates, it drives the stepper motor stator block 1 located inside the placement slot 2221 to rotate and wind. The structure is simple, not affected by the surrounding structure, and the stator does not need to be displaced back and forth during winding. It has high stability and high winding quality.

[0027] Please see Figure 2 , 34. The winding auxiliary displacement guide assembly 23 includes an electric telescopic rod 231, a bushing 232, and a guide frame 233. The bushing 232 is sleeved on the outer circumferential wall of the winding rotating disk 222 located inside the through hole 2211. When the winding support disk 221 rotates, the bushing 232 can slide on it. Limiting blocks 2321 are provided in the slots 2212 on both sides of the outer wall of the bushing 232. The guide frame 233 is symmetrically installed on the limiting blocks 2321 and is set in an inclined structure. Each guide frame 233 has a guide plate 2331 connected to the inner wall of one end near the stepper motor stator block 1. The inner wall of each guide plate abuts against the outer wall of the winding of the stepper motor stator block 1. The electric telescopic rod 231 is located on the workbench 21 on one side of the drive motor 24. The output end of the electric telescopic rod 231 is connected to the outer wall of one of the limit blocks 2321. The bottom of the output end of the electric telescopic rod 231 is connected to a connecting crossbar 2311. The connecting crossbar 2311 is connected to the outer wall of another limit block 2321.

[0028] It should be noted that in this embodiment, the design of the line-assisted displacement guide component 23 is very ingenious. Through the coordinated work of the electric telescopic rod 231, the bushing 232 and the guide frame 233, it achieves precise displacement and stable guidance during the winding process.

[0029] The electric telescopic rod 231 is located on the workbench 21 on one side of the drive motor 24, providing a power source for adjusting the position of the limit block 2321, thereby affecting the position of the guide frame 233 and the guide plate 2331. The output end of the electric telescopic rod is connected to the outer wall of one of the limit blocks 2321, and at the same time, the bottom of its output end is also connected to a connecting crossbar 2311, which is connected to the outer wall of the other limit block 2321, forming a stable support structure.

[0030] The bushing 232 is fitted on the outer circumferential wall of the winding rotary disk 222 inside the through hole 2211, allowing the bushing 232 to slide and move on the winding support disk 221 when it rotates, thereby adapting to various dynamic changes during the winding process. Limiting blocks 2321 are provided in the slots 2212 on both sides of the outer wall of the bushing 232. The limiting blocks 2321 are used to install and fix the guide frame 233.

[0031] Two guide frames 233 are symmetrically mounted on the limiting block 2321 and arranged in an inclined structure. Each guide frame 233 has a guide plate 2331 connected to its inner wall near the end of the stepper motor stator block 1. The guide plate 2331 abuts against the outer wall of the winding of the stepper motor stator block 1, providing stable winding guidance.

[0032] The 233 guide frame is connected to the bushing 232 and the electric telescopic rod 231 through the limit block 2321 to form an integral structure, which ensures that the winding copper wire can be stably and accurately guided during the winding process, and ensures that the copper wire is evenly wound on the stepper motor stator block 1. It realizes precise control and stable guidance during the winding process, which not only improves the winding efficiency and quality, but also reduces the operation difficulty and cost. It is an important technological innovation in the motor manufacturing industry.

[0033] The working process of this utility model:

[0034] In use, place the stepper motor stator block 1 in the placement slot 2221 of the winding rotary disk 222 and ensure it is fixed and stable. Turn on the power, start the control system, and set the winding parameters, such as winding speed, tension, and number of turns, through the control system. Ensure that the lead-out assembly, drive assembly, and winding auxiliary displacement guide assembly 23 are in their initial positions, ready to start winding. Start the drive motor 24, which drives the winding rotary disk 222 and the stepper motor stator block 1 to rotate. The lead-out assembly starts working, and the winding copper wire is led out from the external wire supply device through the lead-out guide cylinder 251, and guided to the stepper motor stator block 1 through the lead-out conical cap 252. The winding auxiliary displacement guide assembly 23... The electric telescopic rod 231 in section 3 adjusts the position of the limit block 2321 as needed. The guide frame 233 and the guide plate 2331 provide stable winding guidance. The guide plate 2331 slides on the stepper motor stator block 1 to ensure that the copper wire is uniformly displaced and wound on the stepper motor stator block. The bushing 232 can slide on the winding support disk 221 when it rotates to adapt to various dynamic changes during the winding process. When the preset number of winding turns or other stopping conditions are reached, the drive motor 24 stops rotating, and the winding rotary disk 222 gradually decelerates to stop. After the winding is completed, the stepper motor stator block 1 is taken out from the placement slot 2221 and is ready for the next step of production or testing.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
