Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of permanent magnet motor processing, and particularly relates to a winding device for a permanent magnet motor. BACKGROUND

[0002] A permanent magnet motor is an electric motor that uses permanent magnets to generate a magnetic field. It generates a constant magnetic field through built-in permanent magnets, without the need for an external power source to generate a magnetic field, so its design is simpler and more compact. At the same time, since no energy is consumed to generate a magnetic field, a permanent magnet motor usually has high efficiency. The application fields of permanent magnet motors are very wide, including industrial drives, transportation, household appliances, aerospace, etc. In the manufacturing process of a permanent magnet motor, copper wire (usually referred to as enameled wire or winding wire) is wound on the stator or rotor structure of the motor. The stator winding is usually formed by winding multiple turns of copper wire (enameled wire) in the slots of the stator core according to a certain rule. These windings are connected to the power supply and will generate a rotating magnetic field when energized, which interacts with the magnetic field generated by the permanent magnets to drive the rotor to rotate.

[0003] Chinese invention CN 118413072 B discloses a winding device for a permanent magnet motor, which belongs to the technical field of permanent magnet motor processing and comprises two groups of winding drums arranged symmetrically, a plurality of groups of blocking seats are arranged on the drum walls of the two groups of winding drums, and winding slots are formed between two adjacent blocking seats; it also comprises an adjusting module and a rotating module; the adjusting module is used to adjust the distance between the two groups of winding drums; the rotating module is used to drive the two winding drums to rotate to wind the copper wire into coils; the rotating module drives the two winding drums to rotate, and the winding drums can wind the copper wire into coils when rotating; based on the selected number of turns of the coil, the rotating module rotates the corresponding number of turns; after winding a group of coils, the copper wire is cut by a shearing mechanism to wind the next group of coils; after all the winding is completed, the coils are taken out; the application adjusts the winding diameter of the coils for different models of permanent magnet motors, has a wider application range, is convenient to operate, and greatly improves the quality, safety and reliability of the winding.

[0004] However, the winding device cannot be wound according to the winding path, and the problem of winding at the same position is prone to occur. Therefore, we propose a winding device for a permanent magnet motor to solve the above problems. SUMMARY

[0005] To achieve the above technical purposes, the technical scheme adopted by the application is as follows:

[0006] The purpose of the application is to solve the problem that the current winding device for a permanent magnet motor cannot be wound according to the winding path, and the winding at the same position is prone to occur.

[0007] To achieve the above technical purposes, the technical scheme adopted by the application is as follows:

[0008] A permanent magnet motor winding device includes a base plate, an adapter seat fixedly mounted on the base plate, an adapter slot provided on the adapter seat, a rotating disk with a central hole rotatably mounted in the adapter slot, a fixed column fixedly mounted on the rotating disk, a fixed shaft fixedly mounted at the end of the fixed column, a rotating roller for winding and unwinding copper wire rotatably mounted on the fixed shaft, and a wire unwinding mechanism for winding and unwinding copper wire on the fixed column.

[0009] The outer side of the rotating disk is provided with several fixed teeth. A drive gear that meshes with the fixed teeth is rotatably installed in the adapter seat. A drive motor is fixedly installed on the back of the adapter seat. The output shaft of the drive motor is fixedly connected to the drive gear. A positioning protrusion is fixedly installed in the adapter groove of the adapter seat. An annular positioning groove that matches the positioning protrusion is opened on the back of the rotating disk. Fixed plates and movable seats are provided on the front and rear sides of the adapter seat on the base plate. A winding mechanism and a drive component that drives the winding mechanism to move back and forth are provided between the fixed plates and the movable seats. The winding mechanism and the unwinding mechanism are located on the same side of the rotating disk.

[0010] Through the above technical solution, the drive motor drives the rotating disk to rotate through the drive gear, so that when the wire feeding mechanism winds the copper wire on the rotating roller onto the winding mechanism, the winding mechanism can be moved back and forth by the drive component to adjust the position of the winding mechanism, thereby making the copper wire wind according to the winding path, avoiding the copper wire from being wound in the same position, which would affect the quality of the wound coil.

[0011] In one possible implementation, the winding mechanism includes two sleeves symmetrically fixedly mounted on the front of the fixed plate, a movable guide rail, a limiting rod laterally fixedly mounted in the movable guide rail, two movable blocks movably mounted on the limiting rod, and two winding drums. The ends of the two sleeves pass through the circular hole in the center of the rotating disk. Two insert rods are fixedly mounted on the back of the movable guide rail. The two insert rods are movably inserted into the two sleeves respectively. The two movable blocks are slidably mounted in the movable guide rail. The two winding drums are fixedly mounted on the ends of the two movable blocks respectively.

[0012] With the above technical solution, when the rotating disk rotates, the two winding drums can wind the copper wire to form a coil of the required specifications.

[0013] In one possible implementation, a fixed guide rail is fixedly installed on the back of the movable seat. A bidirectional threaded rod is rotatably installed laterally inside the fixed guide rail. Two drive blocks are threadedly connected to the two opposite threads of the bidirectional threaded rod. The two drive blocks are slidably installed inside the fixed guide rail. An extension rod is fixedly installed on the back of each of the two drive blocks. The two extension rods pass through the interior of two winding drums respectively. A first motor is fixedly installed on the fixed guide rail. The output shaft of the first motor passes through the fixed guide rail and is fixedly connected to one end of the bidirectional threaded rod.

[0014] With the above technical solution, when the first motor is working, it drives the bidirectional threaded rod to rotate, which can drive the two drive blocks to move towards or away from each other inside the fixed guide rail. Then, by adjusting the distance between the two winding drums through the extension rod, coils of different sizes can be wound.

[0015] In one possible implementation, the drive assembly includes a reciprocating lead screw, a shuttle movably mounted on the reciprocating lead screw, and a connecting rod fixedly mounted between the shuttle and the movable guide rail. A first gear is fixedly mounted at one end of the reciprocating lead screw, and an adapter is fixedly mounted at the other end. A groove adapted to the adapter is provided on the fixed plate. An mounting rod is fixedly mounted on the fixed plate, and the end of the mounting rod is rotatably connected to the end of the reciprocating lead screw. An arc-shaped rack adapted to the first gear is provided in the circular hole of the rotating disk.

[0016] With the above technical solution, when the rotating disk rotates once and the copper wire is wound once on the two winding drums, the arc-shaped rack will drive the reciprocating screw to rotate through the first gear, thereby pushing the shuttle, connecting rod and movable guide rail to move, which can adjust the position of the two winding drums, so that the copper wire wound on the next turn will naturally transition to the position adjacent to the copper wire wound on the previous turn, avoiding the problem of the copper wire being wound in the same position on the winding drum.

[0017] In one possible implementation, the wire feeding mechanism includes a fixed block with an internal mounting cavity, two wire feeding wheels rotatably mounted in the mounting cavity, two second gears respectively fixedly mounted on the two wire feeding wheels, and a second motor fixedly mounted on the fixed block. A bent rod is fixedly mounted on the fixed column, and the fixed block is fixedly mounted on the bent rod. An annular groove is formed in the middle of the two wire feeding wheels, and a plurality of first anti-slip strips are fixedly mounted evenly at intervals in the annular groove. A through groove is formed on the fixed block, and the copper wire on the rotating roller passes through the through groove and the two wire feeding wheels. The two second gears mesh with each other, and the output shaft of the second motor is fixedly connected to one of the second gears.

[0018] With the above technical solution, when the second motor is working, it will release the copper wire through the wire feeding wheel, and the two wire feeding wheels will clamp the copper wire that passes through. When winding the coil, the copper wire will be tightened, so that the wound coil is more compact.

[0019] In one possible implementation, a dovetail groove is provided on the base plate, a fixing strip is fixedly installed at the lower end of the movable seat, the fixing strip is slidably installed in the dovetail groove, a fixing rod is fixedly installed on the base plate, a rotating handle is rotatably installed on the fixing rod, a threaded rod is fixedly installed at the end of the rotating handle, and a threaded seat that is threadedly connected to the threaded rod is fixedly installed on the movable seat.

[0020] With the above technical solution, rotating the screw rod by turning the handle can generate a pushing force on the movable seat. The fixing bar at the lower end of the movable seat is limited by the dovetail groove. When the movable seat is under force, it will move along the direction of the dovetail groove, and the position of the movable seat can be adjusted.

[0021] In one possible implementation, the winding drum has multiple slots, each slot having a movably engaged positioning piece, and a compression spring is fixedly installed between the positioning piece and the slot wall.

[0022] The above technical solution uses a positioning plate to limit the coil, preventing the copper wire from rolling out of the winding drum and affecting the coil winding process.

[0023] In one possible implementation, the positioning piece is provided with a plurality of second anti-slip strips, which are evenly spaced along the length of the positioning piece.

[0024] The above technical solutions increase the contact area and frictional resistance, preventing the copper wire from coming out of the slot or shifting during the winding process.

[0025] In one possible implementation, the movable guide rail and the fixed guide rail are of the same length, and both are less than the diameter of the circular hole on the rotating disk.

[0026] With the above technical solution, when the two winding drums move between the movable guide rail and the fixed guide rail, they will not obstruct the movement of the rotating disk and the structure on the rotating disk.

[0027] In one possible implementation, the outer surface of the rotating roller is provided with anti-slip texture.

[0028] By increasing the roughness of the contact surface, the above technical solution effectively prevents the copper wire from shifting or loosening due to slippage during the winding process, thus ensuring the uniformity and stability of the winding.

[0029] The invention employing the above technical solution has the following advantages:

[0030] 1. In this invention, the drive motor drives the rotating disk to rotate through the drive gear, so that when the wire feeding mechanism winds the copper wire on the rotating roller onto the winding mechanism, the winding mechanism can be moved back and forth by the drive component to adjust the position of the winding mechanism, thereby making the copper wire wind according to the winding path, avoiding the copper wire from being wound in the same position, which would affect the quality of the wound coil.

[0031] 2. In this invention, when the first motor is working, it drives the bidirectional threaded rod to rotate, which can drive the two drive blocks to move towards or away from each other inside the fixed guide rail. Then, by adjusting the distance between the two winding drums through the extension rod, coils of different sizes can be wound.

[0032] 3. In this invention, when the rotating disk rotates one revolution, the arc-shaped rack drives the first gear and the reciprocating screw to rotate, and the shuttle moves on the reciprocating screw, which can drive the connecting rod and the movable guide rail to move along the sleeve direction, thereby adjusting the position of the winding drum to receive the copper wire released from the wire feeding mechanism. During this process, the shuttle moves back and forth, which can make the coil wound on the winding drum tightly attached to the previous coil for winding, and the winding is more compact.

[0033] 4. In this invention, when the second motor is working, it will release the copper wire through the wire feeding wheel, and the two wire feeding wheels will clamp the copper wire that passes through. When winding the coil, the copper wire will be tightened, thereby making the wound coil more compact. Attached Figure Description

[0064] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures, and should not be construed as limiting the present invention. In order to better illustrate the embodiments of the present invention, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product size; it is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the figures.

[0065] In the figures of this invention, the same or similar reference numerals correspond to the same or similar components. In the description of this invention, it should be understood that if terms such as "upper," "lower," "left," "right," "front," and "rear" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the figures are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0066] like Figures 1-13As shown, a permanent magnet motor winding device of the present invention includes a base plate 1, an adapter 2 fixedly mounted on the base plate 1, an adapter groove provided on the adapter 2, a rotating disk 21 with a central hole rotatably mounted in the adapter groove, a fixing post 22 fixedly mounted on the rotating disk 21, a fixing shaft 23 fixedly mounted at the end of the fixing post 22, a rotating roller 24 for winding copper wire rotatably mounted on the fixing shaft 23, the end of the fixing shaft 23 passing through the center of the rotating roller 24, and a locking bolt threadedly connected to one end of the rotating roller 24, which facilitates the disassembly and assembly of the rotating roller 24; the fixing post 22 is provided with a wire feeding mechanism for winding and unwinding the copper wire on the rotating roller 24.

[0067] The outer side of the rotating disk 21 is provided with several fixed teeth. A drive gear 25 that meshes with the fixed teeth is rotatably installed in the adapter 2. A drive motor 26 is fixedly installed on the back of the adapter 2. The output shaft of the drive motor 26 is fixedly connected to the drive gear 25. A positioning protrusion 27 is fixedly installed in the adapter groove of the adapter 2. An annular positioning groove that matches the positioning protrusion 27 is opened on the back of the rotating disk 21. The positioning protrusion 27 extends into the annular positioning groove to prevent the rotating disk 21 from disengaging from the adapter groove. A fixed plate 3 and a movable seat 4 are provided on the base plate 1 on the front and rear sides of the adapter 2. A winding mechanism and a drive component that drives the winding mechanism to move back and forth are provided between the fixed plate 3 and the movable seat 4. The winding mechanism and the unwinding mechanism are located on the same side of the rotating disk 21.

[0068] Through the above technical solution, the drive motor 26 drives the rotating disk 21 to rotate through the drive gear 25. When the wire feeding mechanism winds the copper wire on the rotating roller 24 onto the winding mechanism, the winding mechanism can be moved back and forth by the drive component to adjust the position of the winding mechanism, so that the copper wire is wound according to the winding path, avoiding the copper wire from being wound in the same position, which would affect the quality of the wound coil.

[0069] The outer surface of the rotating roller 24 is provided with anti-slip texture (not shown in the figure).

[0070] By increasing the roughness of the contact surface, the above technical solution effectively prevents the copper wire from shifting or loosening due to slippage during the winding process, thus ensuring the uniformity and stability of the winding.

[0071] In one possible embodiment, the winding mechanism includes two sleeves 31 symmetrically fixedly mounted on the front of the fixed plate 3, a movable guide rail 32, a limiting rod 33 laterally fixedly mounted in the movable guide rail 32, two movable blocks 34 movably mounted on the limiting rod 33, and two winding drums 35. When the first motor 45 is working, it drives the bidirectional threaded rod 42 to rotate, which can drive the two driving blocks 43 to move towards or away from each other inside the fixed guide rail 41. Then, the distance between the two winding drums 35 can be adjusted by the extension rod 44, so that coils of different sizes can be wound. The ends of the two sleeves 31 pass through the circular hole in the center of the rotating disk 21. Two insert rods 321 are fixedly mounted on the back of the movable guide rail 32. The two insert rods 321 are movably inserted into the two sleeves 31 respectively. The two movable blocks 34 are slidably mounted in the movable guide rail 32. The two winding drums 35 are fixedly mounted on the ends of the two movable blocks 34 respectively.

[0072] With the above technical solution, when the rotating disk 21 rotates, the two winding drums 35 can wind the copper wire to form a coil of the required specifications.

[0073] A fixed guide rail 41 is fixedly installed on the back of the movable seat 4. A bidirectional threaded rod 42 is rotatably installed in the fixed guide rail 41. Two drive blocks 43 are threadedly connected to the two opposite threads of the bidirectional threaded rod 42. The two drive blocks 43 are slidably installed in the fixed guide rail 41. An extension rod 44 is fixedly installed on the back of each of the two drive blocks 43. The two extension rods 44 pass through the interior of the two winding drums 35 respectively. A first motor 45 is fixedly installed on the fixed guide rail 41. The output shaft of the first motor 45 passes through the fixed guide rail 41 and is fixedly connected to one end of the bidirectional threaded rod 42. The movable guide rail 32 and the fixed guide rail 41 have the same length, and the length of each is smaller than the diameter of the circular hole on the rotating disk 21.

[0074] With the above technical solution, when the first motor 45 is working, it drives the bidirectional threaded rod 42 to rotate, which can drive the two drive blocks 43 to move towards or away from each other inside the fixed guide rail 41. Then, by adjusting the distance between the two winding drums 35 through the extension rod 44, coils of different sizes can be wound.

[0075] In one possible embodiment, the drive assembly includes a reciprocating lead screw 5, a shuttle 51 movably mounted on the reciprocating lead screw 5, and a connecting rod 52 fixedly mounted between the shuttle 51 and the movable guide rail 32. A first gear 53 is fixedly mounted at one end of the reciprocating lead screw 5, and an adapter is fixedly mounted at the other end. A groove adapted to the adapter is provided on the fixing plate 3. An mounting rod 36 is fixedly mounted on the fixing plate 3. The end of the mounting rod 36 is rotatably connected to the end of the reciprocating lead screw 5. An arc-shaped rack 211 adapted to the first gear 53 is provided in the circular hole of the rotating disk 21. The arc-shaped rack 211 is fixed to the inner side of the rotating disk 21 by bolts. Arc-shaped racks 211 of different lengths can be selected to adjust the distance that the movable guide rail 32 and the winding drum 35 are pushed each time, which is suitable for winding coils of different specifications.

[0076] The wire feeding mechanism includes a fixed block 6 with an internal mounting cavity, two wire feeding wheels 61 rotatably mounted in the mounting cavity, two second gears 62 respectively fixedly mounted on the two wire feeding wheels 61, and a second motor 63 fixedly mounted on the fixed block 6. A bent rod 221 is fixedly mounted on the fixed column 22, and the fixed block 6 is fixedly mounted on the bent rod 221. An annular groove 611 is opened in the middle of the two wire feeding wheels 61. Several first anti-slip strips 612 are evenly fixedly installed in the annular groove 611. The first anti-slip strips 612 can increase the friction between the wire feeding wheel 61 and the copper wire, and can tighten the copper wire during the winding process to make the wound coil tighter. A through groove is opened on the upper part of the fixed block 6. The copper wire on the rotating roller 24 passes through the through groove and the two wire feeding wheels 61. The two second gears 62 mesh with each other, and the output shaft of the second motor 63 is fixedly connected to one of the second gears 62.

[0077] With the above technical solution, when the second motor 63 is working, it will release the copper wire through the wire feeding wheel 61, and the two wire feeding wheels 61 will clamp the copper wire that passes through. When winding the coil, the copper wire will be tightened, so that the wound coil is more compact.

[0078] In one possible embodiment, a dovetail groove 11 is formed on the base plate 1, and a fixing strip 46 is fixedly installed at the lower end of the movable seat 4. The fixing strip 46 is slidably installed in the dovetail groove 11. A fixing rod 12 is fixedly installed on the base plate 1, and a rotating handle 13 is rotatably installed on the fixing rod 12. A threaded rod 14 is fixedly installed at the end of the rotating handle 13. A threaded seat 47 that is threadedly connected to the threaded rod 14 is fixedly installed on the movable seat 4. By rotating the handle 13, the threaded rod 14 can be driven to rotate, thereby driving... The movable seat 4 moves along the direction of the dovetail groove 11. The winding drum 35 has multiple slots 351, and each slot 351 is movably engaged with a positioning piece 352. A compression spring 353 is fixedly installed between the positioning piece 352 and the groove wall of the slot 351. When the coil is wound, the movable seat 4 is moved away from the adapter seat 2, so that the insertion rod 321 is disengaged from the winding drum 35. At this time, the winding drum 35 is in a movable state and can move freely on the movable guide rail 32, which makes it easy to remove the coil from the winding drum 35.

[0079] The contact surface of the positioning piece 352 is provided with a number of second anti-slip strips (not shown in the figure). The second anti-slip strips are made of rubber and are arranged at equal intervals along the length of the positioning piece 352.

[0080] The above technical solution increases the contact area and frictional resistance, preventing the copper wire from coming out of or shifting from the slot 351 during the winding process.

[0081] The method of using this invention is as follows:

[0082] In use, the end of the copper wire is passed through the through slot and between the two wire feeding wheels 61, and then fixed on one of the winding drums 35. The drive motor 26 works and drives the rotating disk 21 to rotate through the drive gear 25. The fixed column 22, the rotating roller 24 and the wire feeding mechanism move in a circle with the rotating disk 21. At this time, the second motor 63 works and drives the two wire feeding wheels 61 to rotate in opposite directions through the two second gears 62, which can slowly release the copper wire on the rotating roller 24.

[0083] When the wire feeding mechanism makes a circular motion, it can wind the copper wire to the outside of the two winding drums 35. When the rotating disk 21 rotates once and the coils on the two winding drums 35 are wound once, the arc-shaped rack 211 drives the first gear 53 to rotate, and the reciprocating screw 5 rotates accordingly, driving the sliding shuttle 51, connecting rod 52 and movable guide rail 32 to move along the sleeve 31. The position of the two winding drums 35 can be adjusted. During subsequent winding, the copper wire will be wrapped tightly against the previous coil on the two winding drums 35, so that the copper wire is wound according to the winding path, so as to avoid the problem of the copper wire being wrapped in the same position, which would affect the coil winding.

[0084] After the coil is wound, the threaded rod 14 can be driven to rotate by turning the handle 13, thereby driving the movable seat 4 to move outward along the direction of the dovetail groove 11 and away from the adapter seat 2. The insertion rod 321 will disengage from the winding drum 35, so that the movable block 34 on the limit rod 33 is in an active state. The winding drum 35 can move freely on the movable guide rail 32, making it easier to remove the coil from the winding drum 35 and making it more convenient to use.
