[0002] Stator coil winding is one of the important components of the motor. Its processing not only affects the performance of the product, but also affects the processing efficiency of the product.

[0003] The winding process of the stator coil winding requires the process steps of paper punching, winding, wire embedding and coil shaping. These process steps are processed by separate equipment respectively.

[0004] Therefore, how to provide an efficient stator winding processing system and processing method is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0005] In view of this, in order to help improve the technical problem of working efficiency of stator winding processing, the present application provides a stator winding processing system and processing method.

The winding and wire-inserting device includes a rotatable carrier platform, a plurality of wire hanging cups are arranged on the carrier platform, and a plurality of winding stations and a wire-inserting station are arranged around the carrier platform. When the wire hanging cups flow to the winding stations, they are wound on the wire hanging cups. When the wound wire hanging cups flow to the wire-inserting station, they are inserted into the stator core, thereby shaping the stator core with the embedded coil. The invention also comprises a coil shaping machine, a second conveyor for conveying the shaped stator core, and a clamping robot for transferring the stator core between various devices. The first conveyor, the paper beating machine, the winding and embedding device, the coil shaping machine and the second conveyor are arranged around the clamping robot, and the embedding station is arranged on the side of the winding and embedding device close to the clamping robot.

The two groups of clamping components are arranged on the same plane and are symmetrically arranged relative to the axis of the end joint shaft, so that the clamping components have the same reference in height and level, reducing the positioning time of the clamping components in the height and horizontal directions, and helping to shorten the time for the clamping components to clamp or place the stator core.

[0013] Optionally, the clamping assembly includes a finger cylinder and a clamping piece fixed on two clamping jaws of the finger cylinder, and the two clamping pieces have clamping openings that are arranged opposite to each other and have shapes that match the outer circumference of the stator core.

While ensuring reliable clamping, it can also help prevent the stator core from being deformed and damaged due to clamping.

[0015] Optionally, the air circuits of the two finger cylinders in the two groups of the clamping assemblies are independent of each other.

When the same wire hanging cup flows to the wire embedding station, the wire embedding mechanism embeds the three-phase winding on the wire hanging cup into the stator core. In addition to winding the three-phase winding embedded in the first stator core, when winding other three-phase windings embedded in the stator core, each time the wire hanging cup flows to a station, the first winding mechanism, the second winding mechanism, the third winding mechanism and the wire embedding mechanism all work simultaneously, thereby achieving high work efficiency.

[0054] The following combination Figures 1 to 4 This application is described in further detail.

[0055] An embodiment of the present application discloses a stator winding processing system.

[0056] A stator winding processing system. Figure 1 and Figure 2 , including a first conveyor 1, a paper punching machine 2, a wire winding and embedding device 3, a coil shaping machine 4, a second conveyor 5, a clamping robot 6 and a control device 7 for controlling the execution of processing actions.

[0057] The first conveyor 1 conveys the stator core entering the system to the discharge end of the first conveyor 1, which faces the clamping robot 6. The discharge end is provided with a first detection switch 12. When the first detection switch 12 detects the stator core, the first detection switch 12 sends a detection signal to the control device 7. The control device 7 controls the first conveyor 1 to stop running, and the stator core stops at the clamping position 11, waiting to be clamped by the clamping robot 6.

[0058] The paper punching machine 2 drives the stator core at the paper punching station 21 to rotate intermittently at a certain time period, and at the same time punches the insulating paper into the wire slots of the stator core;

[0059] The winding and inserting device 3 includes a rotatable supporting platform 31, on which a plurality of wire hanging cups 311 are arranged. A plurality of winding stations and a wire inserting station 351 are arranged around the supporting platform 31. When the wire hanging cups 311 flow to the winding stations, coils are wound on the wire hanging cups 311. When the wound wire hanging cups 311 flow to the wire inserting station 351, the stator core is inserted with wire. The stator core after insertion is removed from the wire inserting station 351, and a stator core without insertion of wire is replaced.

[0060] After the stator core is wire-embedded, in order to facilitate subsequent processing operations, the stator core after wire-embedded needs to be shaped on a coil shaping machine 4, and a shaping station 41 is correspondingly provided on the coil shaping machine 4;

[0061] The second conveyor 5 conveys the shaped stator core to the next workstation. The second conveyor 5 has a placement position 51 at its input end. The placement position 51 is correspondingly provided with a second detection switch 52. When the second detection switch 52 detects the stator core, the second detection switch 52 sends a detection signal to the control device 7. The control device 7 controls the second conveyor 5 to start running and convey the stator core in the placement position 51 to the next workstation. The placement position 51 is vacant, waiting for the next stator core to be placed.

[0062] The first conveyor 1, the paper punching machine 2, the winding and inserting device 3, the coil shaping machine 4 and the second conveyor 5 are arranged around the clamping robot 6. The inserting station 351 of the winding and inserting device 3 is arranged on the side of the winding and inserting device 3 close to the clamping robot 6. The clamping robot 6 clamps the stator core of the first conveyor 1 from the clamping position 11 and transfers it to the paper punching station 21 of the paper punching machine 2, and removes the stator core that has been punched at the paper punching station 21 and transfers it to the inserting station 351 of the winding and inserting device 3. The stator core with wire embedded is clamped and transferred to the shaping station 41. The stator core that has been shaped at the shaping station 41 is clamped and transferred to the placement position 51 of the second conveyor 5. The control device 7 controls the first conveyor 1, the paper punching machine 2, the winding and embedding device 3, the coil shaping machine 4, the second conveyor 5 and the clamping robot 6 to perform processing actions. The stator core is clamped by the clamping robot 6 and transferred between various devices, which shortens the turnover time of the stator core between various devices and improves the production efficiency of the stator winding processing.

[0063] Reference Figure 3 and Figure 4 The clamping robot 6 includes an industrial robot 61 and a clamp 62 for clamping the stator core, which is fixedly installed on the end joint shaft of the industrial robot 61. The clamp 62 is installed at the free end of the end joint shaft of the industrial robot 61, which is convenient for clamping or placing the stator core on the workstation of each equipment. The stator core can be transported between various equipment by rotating and extending the joint shaft of the industrial robot 61, shortening the turnover time of the stator core and helping to improve the overall production efficiency of the stator winding processing.

[0064] Reference Figure 3 and Figure 4 The clamp 62 includes a first clamping component 621 and a second clamping component 622, which are respectively arranged on the same plane and symmetrically arranged relative to the axis of the end joint axis of the industrial robot 61. When loading and unloading at each workstation, the stator core unloading material that has been completed in this process is clamped by the first clamping component 621 or the second clamping component 622, and the stator core loading material to be processed in this process is clamped by the second clamping component 622 or the first clamping component 621, which reduces the back-and-forth motion trajectory of the clamping robot 6 and shortens the time for loading and unloading the stator core. The two groups of clamping components are arranged on the same plane and symmetrically arranged relative to the axis of the end joint axis, so that the clamping components have the same reference in height and level, reducing the positioning time of the clamping components in height and horizontal directions, which helps to shorten the time for the clamping components to clamp or place the stator core.

[0065] Reference Figure 3 and Figure 4The first clamping assembly 621 includes a first finger cylinder 6211 and a first clamping piece 6212. The first clamping piece 6212 is fixed on the two clamping claws of the first finger cylinder 6211. The two first clamping pieces 6212 have first clamping openings 62121 that are oppositely arranged and whose shapes are adapted to the outer circumference of the stator core. The structure of the second clamping assembly 622 is the same as that of the first clamping assembly 621, including a second finger cylinder 6221 and a second clamping piece 6222. The second clamping piece 6222 is provided with a second clamping opening 62221. The first clamping opening 62121 and the second clamping opening 62221 are provided on the second clamping piece 6222. 221 can make the stator core be subjected to uniform force when clamping. The first finger cylinder 6211 and the second finger cylinder 6221 are connected to the power air source, and the clamping force of the first finger cylinder 6211 and the second finger cylinder 6221 can be adjusted by adjusting the air pressure; the air paths of the first finger cylinder 6211 and the second finger cylinder 6221 are independent of each other, which helps to control the movements of the first finger cylinder 6211 and the second finger cylinder 6221 separately, realize the alternating unloading and loading of the stator core, reduce the running trajectory of the clamping robot 6 to clamp the stator core back and forth, and improve the operating efficiency.

[0066] Reference Figure 3 and Figure 4 The gripping robot 6 is specifically a six-degree-of-freedom industrial robot 61. The six-degree-of-freedom industrial robot 61 includes six joint axes, each of which can move independently, allowing it to move in six directions. These six directions are: up and down (along the Z axis), forward and backward (along the Y axis), left and right (along the X axis), rotation around the X axis, rotation around the Y axis, and rotation around the Z axis. The joint axes can flexibly move in six degrees of freedom, allowing for complex movements and operations in three-dimensional space, thereby achieving more precise and efficient operations. This facilitates the first gripping assembly 621 and the second gripping assembly 622 to grip or place the stator core at various workstations, helping to improve the efficiency of unloading and loading materials.

[0067] Reference Figure 1 and Figure 2, the winding and embedding device 3 of the embodiment of the present application has three winding mechanisms, namely the first winding mechanism 32, the second winding mechanism 33 and the third winding mechanism 34. The winding and embedding device 3 of the embodiment of the present application can be a winding mechanism of other numbers, which is determined according to the number of windings of the motor matched with the stator core. A winding mechanism is set corresponding to each winding station, the first winding mechanism 32 corresponds to the first winding station 321, the second winding mechanism 33 corresponds to the second winding station 331, and the third winding mechanism 34 corresponds to the third winding station 341. It is preset that the wire hanging cup 311 flows from the first winding station 321 to the second winding station 331, and from the second winding station 331 to the third winding station The wire station 341 flows from the third winding station 341 to the wire embedding station 351. A wire embedding mechanism 35 is provided at the wire embedding station 351. The second winding mechanism 33 is arranged opposite to the wire embedding mechanism 35. The winding mechanism is arranged above the winding station. The wire embedding mechanism 35 is arranged at both ends of the wire embedding station 351. The stator core is positioned at the wire embedding station 351. The wire hanging cup 311 is wound when it flows to the winding station. When the wound wire hanging cup 311 flows to the wire embedding station 351, the wire embedding mechanism 35 embeds the coil on the wire hanging cup 311 into the stator core. The structural layout of the winding and embedding device 3 is compact, and the wire hanging cup 311 has high circulation efficiency in the winding station and the wire embedding station 351.

[0068] Reference Figure 1 and Figure 2 In the embodiment of the present application, four wire hanging cups 311 are evenly distributed on the carrier 31. Other embodiments of the present application may have other numbers of wire hanging cups 311. The number of wire hanging cups 311 is determined according to the number of motor windings matched with the stator core. The number is one more than the number of motor windings. The wire hanging cup 311 can rotate around its own axis, so that the same wire hanging cup 311 can be used to wind the winding coils of the corresponding phase at different winding stations. The first winding mechanism 32 winds the first phase winding on the same wire hanging cup 311, and the second winding mechanism 33 winds the first phase winding on the same wire hanging cup 311. The second-phase winding is wound on the upper part, and the third winding mechanism 34 winds the third-phase winding on the same wire hanging cup 311. When the same wire hanging cup 311 flows to the wire embedding station 351, the wire embedding mechanism 35 embeds the three-phase winding on the wire hanging cup 311 into the stator core. Except for the initial production of the three-phase winding embedded in the first stator core, during the winding of other three-phase windings embedded in the stator core, every time the wire hanging cup 311 flows to a station, the first winding mechanism 32, the second winding mechanism 33, the third winding mechanism 34 and the wire embedding mechanism 35 all work simultaneously, and the work efficiency is high.

[0069] The control device 7 is respectively communicated with the first conveyor 1, the paper punching machine 2, the winding and embedding device 3, the coil shaping machine 4, the second conveyor 5 and the clamping robot 6. The control device 7 can be a programmable logic controller. Through the control of each device by the control device 7, the stator core is circulated between the devices, realizing the automated production of the stator core such as loading and conveying, transportation, paper punching, winding and embedding, coil shaping, and unloading and conveying.

[0070] The embodiment of the present application also discloses a stator winding processing method.

The stator core is connected to the wire groove of the core, the clamping robot 6 rotates to the direction of the first conveyor 1, the first clamping component 621 clamps the stator core again from the clamping position 11 on the first conveyor 1 and leaves the first conveyor 1, the first conveyor 1 conveys the stator core again and stops at the clamping position 11, the clamping robot 6 rotates to the paper punching machine 2 position, the second clamping component 622 clamps the stator core after paper punching and leaves the paper punching station 21, and then the first clamping component 621 places the stator core that has not been punched into the paper punching station 21 of the paper punching machine 2, waiting for paper punching;

[0073] The clamping robot 6 is controlled to rotate to the wire-inserting station 351 of the winding and wire-inserting device 3. When it is detected that there is no stator core in the wire-inserting station 351, the second clamping assembly 622 of the clamping robot 6 places the stator core after paper punching into the wire-inserting station 351. When it is detected that there is a stator core with coils embedded in the wire-inserting station 351, the first clamping assembly 621 of the clamping robot 6 clamps the stator core with coils embedded and leaves the wire-inserting station 351. The second clamping assembly 622 places the stator core after paper punching into the wire-inserting station 351.

When there is no stator core at the shaping station 41, the first clamping assembly 621 of the clamping robot 6 places the stator core with the coil embedded therein to the shaping station 41. When there is a shaped stator core at the shaping station 41, the second clamping assembly 622 of the clamping robot 6 clamps the shaped stator core and leaves the shaping station 41. Then, the first clamping assembly 621 places the stator core to be shaped at the shaping station 41 of the coil shaping machine 4.

[0076] The clamping robot 6 is controlled to rotate to the second conveyor 5. The second clamping component 622 of the clamping robot 6 places the shaped stator core on the placement position 51 of the second conveyor 5. After the second detection switch 52 detects the stator core at the placement position 51, it starts the second conveyor 5 to transport the shaped stator core to the next workstation.

[0077] The stator core performs different processing steps on various devices in the system. The stator core is clamped and transported by the clamping robot 6, which greatly improves the efficiency of processing and production.

[0078] The winding and embedding device 3 winds the wire hanging cup 311 and embeds the coil into the stator core, and further comprises the following steps:

[0079] When initially winding the three-phase winding of the first stator core, the first winding mechanism 32 is controlled to work and the first phase winding is wound on the wire hanging cup 311 located at the first winding station 321;

[0082] Control four wire hanging cups 311 to simultaneously flow through one workstation, and at the same time, the four wire hanging cups 311 rotate through one winding position;

[0083] Control the first winding mechanism 32 to wind the first phase winding on the wire hanging cup 311 located at the first winding station 321; control the second winding mechanism 33 to wind the second phase winding on the wire hanging cup 311 located at the second winding station 331; control the third winding mechanism 34 to wind the third phase winding on the wire hanging cup 311 located at the third winding station 341;

[0084] Control four wire hanging cups 311 to simultaneously flow through one workstation, and at the same time, the four wire hanging cups 311 rotate through one winding position;

[0086] By controlling the four wire hanging cups 311 to flow through one workstation at a time, and the wire hanging cup 311 rotates one winding position, when winding the three-phase winding of the first stator core, the wire hanging cup 311 corresponding to the first stator core is in the first winding workstation 321, and the first winding mechanism 32 works to wind the first phase winding. When the wire hanging cup 311 corresponding to the first stator core flows to the second winding workstation 331, the second winding mechanism 33 works to wind the second phase winding, and the wire hanging cup 311 corresponding to the first stator core flows to the third winding workstation At 341, the third winding mechanism 34 works to wind the third phase winding. When the wire hanging cup 311 corresponding to the first stator core flows to the wire embedding station 351, the wire embedding mechanism 35 works to embed the first phase winding, the second phase winding and the third phase winding into the wire slots of the stator core at the same time. Starting from the production of the second stator core, each time the wire hanging cup 311 flows to a station, the first winding mechanism 32, the second winding mechanism 33, the third winding mechanism 34 and the wire embedding mechanism 35 can work simultaneously, which greatly improves the work efficiency of winding and embedding.
