Description

Technical Field

[0001] This invention relates to the field of stator core winding technology, and in particular to a stator core winding device and winding method. Background Technology

[0002] The stator core is the core of the motor's magnetic circuit and the mechanical carrier of the windings. It is made of laminated silicon steel sheets. Its core function is to provide a low magnetic resistance path for the magnetic field generated by the stator windings, constrain the magnetic flux distribution, and improve the electromagnetic conversion efficiency. The inner circle of the stator core has slots that can be embedded to form windings of metal wire cores. During motor driving, after being energized, the windings form a controllable rotating magnetic field on the stator core, thereby driving the rotor located inside the stator to rotate, realizing the electromechanical energy conversion, and thus driving the output end of the motor to rotate, generating a rotational driving force on the object.

[0003] The stator core has multiple slots on its circumference. In the existing stator core winding device, the wire core is wound around the stator tooth area between two adjacent slots. Each stator tooth area is wound with wire core to form a winding. The windings wound in several corresponding stator tooth areas use the same wire core to achieve the connection of multiple windings. When winding the wire core on the stator core, the winding device adopts a winding process with multiple stator tooth areas at intervals and drives the stator core to rotate two revolutions to complete the winding process of multiple parts of the stator core.

[0004] In existing winding devices, multiple wire core joints are generated when winding the stator core. Each wire core joint is several centimeters long. When the stator core rotates to the second revolution and winding is performed on other stator tooth areas, although two baffles are used to prevent interference between the wire core joints and the winding area, there is still a problem that the wire core joints can be entangled in the winding position when they are adjacent to the winding position, causing the stator core winding to fail. Summary of the Invention

[0005] To solve the above-mentioned technical problems, embodiments of the present invention provide a stator core winding device and winding method, which achieves the technical effect of clamping and guiding the core joints generated after winding, and preventing the core joints from interfering with each other with the winding area.

[0006] To achieve the above objectives, embodiments of the present invention provide a stator core winding device, including a winding machine tool, wherein the winding machine tool is equipped with multiple rotary winding devices, each of the rotary winding devices includes a rotation drive device for driving a support shaft seat to rotate, the stator core is sleeved on the support shaft seat, and further includes: Abutment support is provided on the upper side of each of the support shaft seats. The bottom of the abutment support is inserted into the support shaft seat. The stator core is clamped between the abutment support and the support shaft seat. The abutment support rotates with the support shaft seat. A lifting cylinder seat is elastically connected to the top of the abutment support. When the abutment support abuts against the stator core, the lifting cylinder seat can move longitudinally on the upper side of the abutment support. The winding machine tool is provided with a lifting slot frame that corresponds one-to-one with the rotating winding equipment. The lifting slot frame is provided with a lifting drive structure that drives the abutment support and the lifting cylinder seat to move longitudinally. The conductor clamps are arranged around the circumference of the abutment support, and each conductor clamp corresponds to a winding point of the stator core. A compression bracket is provided on the side of the lifting cylinder seat near the rotating winding device. The compression bracket is moved to compress and move to the wire core clamp near the rotating winding device to abut against the wire core. A wire core cutting assembly is provided on the lifting cylinder base for cutting off the clamped wire core.

[0007] In one possible implementation, the top of the support shaft seat is provided with an engagement slot, and the bottom of the abutment support is fixedly connected with an engagement rod, which engages with the engagement slot.

[0008] In one possible implementation, a telescopic rod is provided between the inner top wall of the lifting cylinder seat and the top end of the abutment support, and a compression spring is sleeved on the outer side of the telescopic rod to accommodate the distance between the lifting cylinder seat and the abutment support.

[0009] In one possible implementation, the lifting drive structure includes a screw lifting assembly, which is disposed within a lifting slot frame. A lifting slide is longitudinally slidably connected within the lifting slot frame, and the lifting slide is in a transmission engagement with the screw lifting assembly. An extension rod is disposed between the lifting slide and the lifting cylinder seat.

[0010] In one possible implementation, the abutment support is provided with a plurality of rotating shaft seats around its circumference, each rotating shaft seat corresponding to a wire core clamp. A mounting shaft is rotatably connected inside each rotating shaft seat, the bottom of the wire core clamp is connected to the mounting shaft, and a spring is provided between the mounting shaft and the rotating shaft seat.

[0011] In one possible implementation, the bottom of the rotating shaft seat is provided with a grooved abutment plate, and after the wire core clamp rotates along the center point of the mounting shaft, the bottom of the wire core clamp abuts against the grooved abutment plate, and abutment side plates are provided on both sides of the wire core clamp.

[0012] In one possible implementation, the extrusion bracket includes an acute-angled connecting bracket, an extrusion strip, and a fastening clamp. The acute-angled connecting bracket is disposed on the lifting cylinder seat, and the bottom of the acute-angled connecting bracket is provided with an extrusion strip that abuts against the bottom of the wire core clamp. The acute-angled connecting bracket is provided with a fastening clamp, and the inner walls on both sides of the fastening clamp abut against the abutting side plate, thereby extruding the wire core clamp towards the center.

[0013] In one possible implementation, the wire core cutting assembly includes a drive cylinder and an abutment socket. The drive cylinder is mounted on the lifting cylinder base, and the abutment socket is provided on the side of each wire core clamp. A wire cutting tool is provided on the output end of the drive cylinder, and the wire cutting tool cooperates with the abutment socket.

[0014] In one possible implementation, the abutment socket is provided with a sloping groove, which, when the wire core is cut, causes the wire core connector to bend and engage with the wire core clamp.

[0015] A method for winding a stator core includes the following steps: S1. Loading: Move the stator core onto the outside of the support shaft seat, causing the abutment support to descend, and fix the stator core between the abutment support and the support shaft seat.

[0016] S2, Wire clamping: Move the wire core port on the rotating winding device to the nearest wire core clamp, causing the lifting cylinder and acute-angle connecting bracket to descend, squeezing the wire core clamp to shift and abut against the wire core.

[0017] S3. Winding: After the wire core is clamped on one side, the rotating winding equipment winds the wire onto the corresponding stator tooth area. After completing a single winding, the stator core is rotated. The winding process is completed by using multiple stator tooth areas with spaced windings.

[0018] S4. Secondary wire clamping: When it is necessary to cut the wire core, the wire core is fixed in one of the wire core clamps, and then the winding process is carried out. After the winding is completed, the wire cutting tool is moved into the abutment socket corresponding to the wire core clamp to cut the wire core. The wire core joint is bent and hooked with the wire core clamp. When the stator iron core rotates, the wire core clamp drives the wire core joint to shift towards the lifting cylinder seat.

[0019] S5. Re-clamping: After the stator core rotates, another stator tooth area corresponds to the rotating winding equipment. At this time, the wire core clamp corresponding to the stator tooth area abuts against the wire core on the rotating winding equipment, and the rotating winding equipment performs the winding process on the stator tooth area again.

[0020] S6. Removal: After completing the winding process for all stator tooth areas on the stator core, the abutment support is raised to remove the stator core.

[0021] Compared with the prior art, the stator core winding device and winding method provided in this embodiment of the invention have the following significant technical advantages: After the stator core is placed on the support shaft seat, the lifting cylinder seat and the abutment support are lowered. After the abutment support is lowered and inserted into the support shaft seat, the stator core is clamped between the abutment support and the support shaft seat. Then, the rotating winding device performs the winding process on the stator tooth area between the two slots corresponding to the stator core. First, one side of the wire core is clamped by the corresponding wire core clamp. Then, the rotating winding device winds the wire core around the stator tooth area. After the wire core is wound, the wire core is cut off. The wire core clamp moves the cut-off part towards the lifting cylinder seat, so that the wire core end is away from the upper side of the winding area, effectively preventing the wire core end from affecting the winding area.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0031] Example 1: A stator core winding device according to one embodiment of the present invention. Please refer to [link to example]. Figure 1 and Figure 2 The system includes a winding machine tool 1, on which multiple rotary winding devices 2 are provided. Each rotary winding device 2 includes a rotary drive device 3 for driving a support shaft seat 4 to rotate. The stator core is sleeved on the support shaft seat 4. The rotary winding device 2 includes a rotating part, a wire output part, and a wire laying part. The wire output part is located at the side end of the rotating part, while the wire laying part corresponds to the axis of the rotating part. The wire output part is used to drive the wire core to wind onto the stator core, while the wire laying part is used to ensure that the wire core is evenly distributed on the stator tooth area between the two slots of the stator core. When the stator core is wound, it is necessary to make the multiple stator tooth areas on the stator core correspond to the positions of the rotary winding devices 2 in sequence. The rotary drive device 3 drives the support shaft seat 4 to rotate, thereby adjusting the circumferential position of the stator core. Both the rotary drive device 3 and the rotary winding device 2 are essential technical structures on the winding machine tool 1 in the prior art and are prior art equipment known to those skilled in the art.

[0032] Also includes the abutment support 5, please refer to Figure 3 and Figure 7Each support shaft seat 4 has an abutment support 5 on its upper side. The bottom of the abutment support 5 is inserted into the support shaft seat 4. The stator core is clamped between the abutment support 5 and the support shaft seat 4. The abutment support 5 rotates with the support shaft seat 4. The top of the support shaft seat 4 has an engagement slot 9. The bottom of the abutment support 5 is fixedly connected to an engagement rod 10. The engagement rod 10 engages with the engagement slot 9. After the stator core is placed on the support shaft seat 4, the abutment support 5 and the lifting cylinder seat 6 are driven to descend, so that the bottom end of the abutment support 5 abuts with the top end of the stator core. After the abutment support 5 is in contact with the top end of the stator core, the engagement rod 10 at the bottom of the abutment support 5 is inserted into the engagement slot 9. The engagement rod 10 engages with the engagement slot 9. When the support shaft seat 4 rotates, the abutment support 5 rotates synchronously.

[0033] The top of the lifting cylinder seat 6 is elastically connected to the abutment support 5. Please refer to [link / reference]. Figure 3 When the abutment support 5 abuts against the stator core, the lifting cylinder seat 6 can move longitudinally on the upper side of the abutment support 5. A telescopic rod 11 is provided between the inner top wall of the lifting cylinder seat 6 and the top of the abutment support 5. A compression spring 12 is sleeved on the outer side of the telescopic rod 11 to adapt to the distance between the lifting cylinder seat 6 and the abutment support 5. The bottom of the telescopic rod 11 is rotatably connected to the abutment support 5, and the abutment support 5 can rotate at the bottom of the telescopic rod 11. After the abutment support 5 and the support shaft seat 4 are inserted, one of the wire core clamps 8 needs to be adjusted. When the position is reached, the lifting cylinder seat 6 continues to move towards the abutment support 5, causing the telescopic rod 11 and the compression spring 12 to compress. At this time, because the engaging rod 10 abuts and engages with the engaging slot 9, the abutment support 5 will not excessively squeeze the stator core. After the lifting cylinder seat 6 rises from the upper side of the abutment support 5, the telescopic rod 11 and the compression spring 12 expand between the lifting cylinder seat 6 and the abutment support 5 to adapt to the position changes of the lifting cylinder seat 6 and the abutment support 5 while ensuring that the position of the abutment support 5 remains unchanged.

[0034] The winding machine tool 1 is equipped with lifting slots 7 that correspond one-to-one with the rotating winding equipment 2. Please refer to [link / reference]. Figure 3The lifting frame 7 is equipped with a lifting drive structure that drives the abutment support 5 and the lifting cylinder seat 6 to move longitudinally. The lifting drive structure includes a screw lifting assembly. The lifting frame 7 is equipped with a screw lifting assembly. A lifting slide 101 is longitudinally slidably connected in the lifting frame 7. The lifting slide 101 is in transmission cooperation with the screw lifting assembly. An extension rod 102 is provided between the lifting slide 101 and the lifting cylinder seat 6. The screw lifting assembly includes a lifting screw 103. The lifting screw 103 is rotatably connected in the lifting frame 7. A motor drive device 104 is provided on the top of the lifting frame 7. The output end of the motor drive device 104 is connected to the lifting screw 103. When the motor drive device 104 is started, the lifting screw 103 is driven to rotate. The lifting slide 101 is in transmission cooperation with the lifting screw 103 through a transmission nut group, so as to realize the longitudinal movement of the lifting slide 101 and the extension rod 102. In this way, by moving the position of the lifting cylinder seat 6, the position of the abutment support 5 can be adjusted, and the drive can be realized for one of the wire core clamps 8.

[0035] Multiple wire core clips 8 are arranged circumferentially on the abutment support 5. Please refer to [link / reference]. Figure 4 , Figure 5 and Figure 6 Each wire core clamp 8 corresponds to a stator core winding point. Multiple rotating shaft seats 13 are arranged on the circumference of the support 5, each corresponding to a wire core clamp 8. A mounting shaft 14 is rotatably connected inside the rotating shaft seat 13. The bottom of the wire core clamp 8 is connected to the mounting shaft 14. A spring 15 is provided between the mounting shaft 14 and the rotating shaft seat 13. During the descent of the lifting cylinder seat 6, when the pressing bracket presses and pushes one of the wire core clamps 8, the wire core clamp 8 and the mounting shaft 14 rotate together along the center point of the mounting shaft 14. The wire core clamp 8 flips towards the rotating winding device 2. During the rotation of the mounting shaft 14, the spring 15 tightens. When the pressing bracket rises, the torque of the spring 15 drives the mounting shaft 14 and the wire core clamp 8 to flip towards the lifting cylinder seat 6, keeping the wire core joint vertical and away from the rotating winding device 2.

[0036] The bottom of the pivot seat 13 is provided with a grooved abutment plate 16, please refer to [reference needed]. Figure 6 After the wire core clamp 8 rotates along the center point of the mounting shaft 14, the bottom of the wire core clamp 8 abuts against the grooved abutment plate 16. Both sides of the wire core clamp 8 are provided with abutment side plates. When the compression bracket pushes the wire core clamp 8 to deflect, the bottom of the wire core clamp 8 will abut against the inner wall of the grooved abutment plate 16, so that the wire core clamp 8 stops deflecting. The abutment side plate has a vertical end face. When the compression bracket squeezes the wire core clamp 8 to deflect, after abutting against the abutment side plate, the wire core clamp 8 will retract to the center and abut against the wire core.

[0037] A compression bracket is provided on the side of the lifting drum base 6 near the rotating winding device 2. Please refer to [link / reference]. Figure 5The extrusion bracket moves to press and move closer to the wire core clamp 8 near the rotating winding device 2, abutting against the wire core. The extrusion bracket includes an acute-angled connecting bracket 201, an extrusion bar 202, and a fastening clamp 203. The acute-angled connecting bracket 201 is mounted on the lifting cylinder seat 6. The extrusion bar 202 is located at the bottom of the acute-angled connecting bracket 201 and abuts against the bottom of the wire core clamp 8. The fastening clamp 203 is located on the acute-angled connecting bracket 201, and both inner walls of the fastening clamp 203 abut against the abutting side plate. The extruded wire core clamp 8 retracts towards the center. During the descent of the lifting cylinder seat 6, the acute-angled connecting bracket 201, the extrusion bar 202, and the fastening clamp are moved together. Simultaneously descending, as the extrusion bar 202 abuts against the bottom of the wire core clamp 8 and causes the wire core clamp 8 to shift, the inner walls on both sides of the fastening clamp 203 also abut against the abutting side plate. The side walls of the fastening clamp 203 are inclined, and the distance between the inner walls on both sides of the fastening clamp 203 is slightly smaller than the distance between the side walls of the opposite ends of the two abutting side plates. Both the fastening clamp 203 and the wire core clamp 8 have a certain degree of elasticity. After the fastening clamp 203 moves to the outside of the two abutting side plates, the clamping force of the fastening clamp 203 towards the center causes the middle of the wire core clamp 8 to close up and abut against the wire core. After the wire core is cut off, the wire core connector is driven to shift towards the lifting cylinder seat 6.

[0038] The lifting cylinder base 6 is equipped with a wire core cutting assembly for cutting off the clamped wire core. Please refer to [link / reference]. Figure 5 The wire core cutting assembly includes a drive cylinder 301 and an abutment socket 302. The drive cylinder 301 is mounted on the lifting cylinder base 6. The abutment socket 302 is provided on the side of each wire core clamp 8. A wire cutting tool 303 is provided on the output end of the drive cylinder 301. The wire cutting tool 303 cooperates with the abutment socket 302. After the wire core clamp 8 abuts against the wire core, the drive cylinder 301 is activated to drive the wire cutting tool 303 to move into the abutment socket 302. After the wire cutting tool 303 contacts the wire core, it enters the abutment socket 302 and cuts the wire core in the sloping groove 304.

[0039] The abutment socket 302 is provided with a sloping groove 304. When cutting the wire core, the wire core connector is bent and hooked with the wire core clamp 8. In order to keep the wire core connector connected to the wire core clamp 8, and to make it easy to remove the wire core connector from the wire core clamp 8 later, when the cutting blade 303 squeezes the wire core into the sloping groove 304, firstly, because the abutment socket 302 is located on one side of the wire core clamp 8, the wire core will shift towards the abutment socket 302 during the cutting process. Secondly, the wire core is cut in the sloping groove 304, and the part of the wire core connector fits against the inner wall of the sloping groove, increasing the degree of bending of the wire core and ensuring that the wire core clamp 8 stably hooks the wire core connector.

[0040] Example 2, please refer to Figures 1 to 7On the other hand, according to the stator core winding device disclosed in this embodiment, the present invention also provides a stator core winding method, which specifically includes the following steps: Step 1, Loading: Move the stator core onto the outside of the support shaft seat 4, causing the abutment support 5 to descend, and fix the stator core between the abutment support 5 and the support shaft seat 4.

[0041] Step 2, clamping the wire: Move the wire core end on the rotating winding device 2 to the nearest wire core clamp 8, causing the lifting cylinder seat 6 and the acute-angle connecting bracket 201 to descend, squeezing the wire core clamp 8 to shift and abut against the wire core.

[0042] Step 3, winding: After the wire core is clamped on one side, the rotating winding device 2 winds the wire onto the corresponding stator tooth area. After completing a single winding, it drives the stator core to rotate. The winding process is completed by using multiple stator tooth areas with interval winding.

[0043] Step 4, Secondary wire clamping: When it is necessary to cut the wire core, fix the wire core in one of the wire core clamps 8, and then perform the winding process. After the winding is completed, drive the wire cutting cutter 303 to move into the abutment socket 302 corresponding to the wire core clamp 8 to cut the wire core. The wire core joint is bent and hooked with the wire core clamp 8. When the stator iron core rotates, the wire core clamp 8 drives the wire core joint to shift towards the lifting cylinder seat 6.

[0044] Step 5, Re-clamping: After the stator core rotates, another stator tooth area corresponds to the rotating winding device 2. At this time, the wire core clamp 8 corresponding to the stator tooth area abuts against the wire core on the rotating winding device 2, and the rotating winding device 2 performs the winding process on the stator tooth area again.

[0045] Step 6, Material Removal: After completing the winding process for all stator tooth areas on the stator core, the abutment support 5 is lifted to remove the stator core.

The wire cutting knife (303) cooperates with the abutment socket (302).

9. A stator core winding device according to claim 8, characterized in that, The abutment socket (302) is provided with a sloping groove (304) so ​​that when the wire core is cut, the wire core joint is bent and hooked with the wire core clamp (8).

10. A method for winding a stator core, using the stator core winding device according to claim 9, characterized in that, Includes the following steps: S1, Loading: Move the stator core onto the outside of the support shaft seat (4), drive the abutment support (5) to descend, and fix the stator core between the abutment support (5) and the support shaft seat (4); S2, clamping wire: move the wire core port on the rotating winding device (2) to the nearest wire core clamp (8), drive the lifting cylinder seat (6) and the acute angle connecting bracket (201) to descend, squeeze the wire core clamp (8) to shift and abut against the wire core; S3, winding: After the wire core is clamped on one side, the rotating winding device (2) winds the wire onto the corresponding stator tooth area, and after completing a single winding, it drives the stator core to rotate, and adopts a winding method with multiple stator tooth areas spaced apart to complete the winding process. S4, Secondary wire clamping: When it is necessary to cut the wire core, the wire core is fixed in one of the wire core clamps (8), and then the winding process is carried out. After the winding is completed, the wire cutting tool (303) is driven to move into the abutment socket (302) corresponding to the wire core clamp (8) to cut the wire core. The wire core joint is bent and hooked with the wire core clamp (8). When the stator iron core rotates, the wire core clamp (8) drives the wire core joint to shift towards the lifting cylinder seat (6). S5. Re-clamping: After the stator core rotates, another stator tooth area corresponds to the rotating winding device (2). At this time, the wire core on the rotating winding device (2) is contacted by the wire core clamp (8) corresponding to the stator tooth area, and the rotating winding device (2) performs the winding process on the stator tooth area again. S6. Removal: After completing the winding process of all stator tooth areas on the stator core, the abutment support (5) is raised to remove the stator core.
