Description

Technical Field

[0001] This invention relates to stator manufacturing, specifically to a control method for an automatic winding device for stator lead wires. Background Technology

[0002] During stator production, the stator leads need to be wound, and then further wound to form three enameled wires into a single unit. In existing production processes, the fixed-point winding of the three enameled wires relies on manual operation. After positioning the three wires at the same location, a winding or stranding mechanism is used to twist them together. However, this manual, single-step operation is inefficient, labor-intensive, and requires a large workforce, making it difficult to keep up with the production frequency of assembly lines and unsuitable for fully automated production lines. Therefore, a control method for an automatic winding device for stator leads is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a control method for an automatic winding device for stator lead wires in order to solve the above problems.

[0004] To achieve the above objectives, the present invention provides a control method for an automatic winding device for stator lead wires, characterized in that the control method is as follows: a. Set the working parameters of the conveying mechanism, lifting mechanism, straightening mechanism, winding mechanism and stranding mechanism, and set the winding path of the winding mechanism for the three enameled wires and the clamping winding point of the winding mechanism for the three enameled wires respectively. b. When the sensor installed at the straightening mechanism senses that the stator has been transported to the straightening mechanism by the conveying mechanism, it sends a signal to the controller. The controller then controls the conveying mechanism to stop and starts the lifting mechanism to lift the tray containing the stator to the set position. c. The controller controls the straightening mechanism to straighten the three enameled wires of the stator in sequence; d. After the straightening work is completed, the winding mechanism sequentially winds the three enameled wires according to the set winding path. After straightening and positioning one enameled wire, the winding mechanism winds the straightened and positioned enameled wire at a fixed point. The straightening and winding work of the three enameled wires is completed in sequence. When the third enameled wire is wound, it wraps around the other two enameled wires several times to form a whole. e. After the winding is completed, the controller controls the lifting mechanism to drive the tray and stator to reset and fall onto the conveying mechanism, and then transport them to the next process.

[0005] Further preferably, the process also includes a stranding process f after step e above. When the sensor at the stranding mechanism senses that the stator has reached the stranding station, it sends a signal to the controller. The controller controls the conveying mechanism to stop operating. Then, the controller controls the lifting mechanism at the stranding mechanism to lift the tray and the stator to the set position. Then, the controller controls the stranding mechanism to strand the three enameled wires that are wound into a whole, and twists the three enameled wires together.

[0006] A further preferred embodiment includes a bending process g after the stranding process. After stranding is completed, the controller controls the bending mechanism to push the stranded enameled wire to bend it. After bending, the controller controls the lifting mechanism to drive the tray and stator to reset and fall onto the conveying mechanism, which then transports it to the next process.

[0007] In a further preferred embodiment, the winding path set in step a above is the travel trajectory and final positioning point of the winding of the three enameled wires by the winding mechanism, and the clamping winding point of the three enameled wires is at the final positioning point after winding.

[0008] More preferably, the clamping and winding points set in step a above are the clamping points where the winding mechanism drives the three enameled wires to wind. The positions of the clamping points of the two enameled wires closest to the final positioning point are set according to the distance between the enameled wire and the final positioning point. The clamping point of the third enameled wire is the distance between the enameled wire and the final positioning point plus the length of the number of turns wound on the other two enameled wires.

[0009] In a further preferred embodiment, in step a above, when winding the three enameled wires, the winding is performed sequentially from the closest to the farthest distance between the three enameled wires and the final positioning point, according to the set winding path. The travel trajectory of the first two enameled wires is that after the winding mechanism clamps the winding point, it moves the clamping winding point on the enameled wire to the final positioning point. The travel trajectory of the third enameled wire is that after the winding mechanism clamps the winding point, it moves the clamping winding point on the enameled wire to the final positioning point, and then winds the wire around the first two enameled wires a set number of times.

[0010] In a further preferred embodiment, in step c above, the straightening mechanism clamps the bottom end of the enameled wire using a clamping device, and then moves upwards through the transition between the straightening device and the enameled wire to straighten the wire.

[0011] The beneficial effects of this invention are as follows: By setting the working parameters of the conveying mechanism, lifting mechanism, straightening mechanism, winding mechanism, and stranding mechanism; and by controlling the conveying mechanism, lifting mechanism, straightening mechanism, winding mechanism, and stranding mechanism to convey the stator, straighten the enameled wire, wind the three enameled wires at fixed points, and strand the three enameled wires after fixed-point winding, the stranding work is completed, forming an automated production line, which improves efficiency and consistency of batch product processing.

[0014] The control method of the automatic winding device for stator lead wires according to the present invention will be further described below with reference to the accompanying drawings.

[0015] See Figure 1-5 The control method of the automatic winding device for stator lead wires shown in the figure is characterized by the following control method: The final positioning point is set as Y, the clamping winding point as D, and the winding length of the third enameled wire is N. The working parameters of the conveying mechanism 1, lifting mechanism 2, straightening mechanism 3, winding mechanism 4, and stranding mechanism 5 are set respectively. The winding path of the winding mechanism 4 for the three enameled wires and the clamping winding point D of the winding mechanism 4 for the three enameled wires are set respectively. The winding path is the travel trajectory of the winding mechanism 4 driving the three enameled wires to wind and the final positioning point Y. The clamping winding point D is the clamping point of the winding mechanism 4 driving the three enameled wires to wind. The position of the clamping point of the two enameled wires closest to the final positioning point Y is set according to the distance between the enameled wire and the final positioning point Y. The clamping point of the third enameled wire is the distance between the enameled wire and the final positioning point Y plus the length N of the number of turns wound on the other two enameled wires. When the sensor located at the straightening mechanism 3 detects that the stator has been conveyed to the straightening mechanism 3 by the conveying mechanism 1, it sends a signal to the controller. The controller then controls the conveying mechanism 1 to stop and controls the lifting mechanism 2 to start, lifting the tray containing the stator to the set position. The lifting mechanism 2 is designed to remove the tray and stator from the straightening mechanism and lift them to the set position. The controller controls the straightening mechanism 3 to straighten the three enameled wires of the stator in sequence. When straightening the enameled wires, the straightening mechanism 3 clamps the bottom end of the enameled wire through the clamping device 7, and then moves upward through the straightening device 8 to straighten the enameled wire. The straightening mechanism 3 straightens the enameled wires to position them and ensures that the clamping points on the enameled wires are consistent when the winding mechanism 4 winds the enameled wires at the correct points. This prevents the winding mechanism 4 from failing to wind the enameled wires due to a misalignment between the position of the enameled wires and the position of the clamping device. After straightening is completed, the winding mechanism 4 sequentially winds three enameled wires according to the set winding path. During winding, the three enameled wires are wound from closest to farthest from the final positioning point Y, following the set winding path. The travel trajectory of the first two enameled wires is as follows: after the winding mechanism clamps the wire at the clamping winding point D, it moves the clamping winding point D on the enameled wire to the final positioning point Y. The travel trajectory of the third enameled wire is as follows: after the winding mechanism clamps the wire at the clamping winding point D, it moves the clamping winding point D on the enameled wire to the final positioning point Y, and then winds the wire around the first two enameled wires for a set number of turns N. Each straightening... After positioning one enameled wire, the winding mechanism 4 straightens and positions the enameled wire and winds it at a fixed point. The straightening and winding of three enameled wires is completed in one go from near to far. The third enameled wire is wrapped around the other two enameled wires several times during the winding process to form a whole. The winding mechanism 4 positions the three enameled wires at a fixed point to form a whole, which makes it easier for the subsequent stranding mechanism 5 to accurately pick up the three enameled wires and perform the stranding work. This avoids the situation where the three enameled wires are loose and in different positions, which would make it impossible to ensure that all three enameled wires are picked up together before stranding. After the winding is completed, the controller controls the lifting mechanism 2 to drive the tray and stator to reset and fall onto the conveying mechanism 1; The controller controls the conveyor mechanism 1 to drive the pallet and stator for conveying; When the sensor at stranding mechanism 5 senses that the stator has reached the stranding station, it sends a signal to the controller. The controller then controls the conveying mechanism 1 to stop. The controller then controls the lifting mechanism 2 at stranding mechanism 5 to lift the tray and stator to the set position. Then the controller controls the twisting mechanism 5 to twist the three enameled wires that are wound into a whole together. After stranding is completed, stranding mechanism 5 is reset; then the controller controls the bending mechanism to push the stranded enameled wire and bend it. Then the controller controls the lifting mechanism 2 to drive the tray and stator to reset, and after falling onto the conveying mechanism 1, they are output through the conveying mechanism 1.
