Description

Technical Field

[0001] The present invention belongs to the technical field of permanent magnet motor processing, and particularly relates to a winding device for a permanent magnet motor. Background Art

[0002] A permanent magnet motor is a motor that uses permanent magnets to generate a magnetic field. It generates a constant magnetic field through the built-in permanent magnets without the need for an external power source to generate the magnetic field. Therefore, its design is simpler and the structure is more compact. At the same time, since there is no need to consume energy to generate the magnetic field, permanent magnet motors usually have higher efficiency. Permanent magnet motors are widely used in various fields, including industrial drives, transportation, household appliances, aerospace, etc. During the manufacturing process of a permanent magnet motor, copper wire (usually called enameled wire or winding wire) is wound around 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 a power source, and when energized, a rotating magnetic field is generated, 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 relates to the technical field of permanent magnet motor processing. It includes two groups of symmetrically arranged winding drums. A number of groups of retaining seats are arranged at intervals on the drum walls of the two groups of winding drums, and a winding groove is formed between two adjacent retaining seats; it also includes an adjustment module and a rotation module; the adjustment module is used to adjust the distance between the two groups of winding drums; the rotation module is used to drive the winding drums on both sides to rotate to wind the copper wire into a coil; the rotation module drives the winding drums on both sides to rotate, and when the winding drums rotate, the copper wire can be wound into a coil. Based on the number of turns of the selected coil, the rotation module rotates the corresponding number of revolutions. After one group of coils is wound, the copper wire is cut by a shearing mechanism to start winding the next group of coils. After all winding is completed, each coil is removed. The present invention adjusts the winding diameter of the coil according to different models of permanent magnet motors, has a wider application range, is easy to operate, and greatly improves the quality, safety and reliability of the winding.

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

[0005] To achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] The objective of the present invention is to solve the problem that the current winding device for a permanent magnet motor cannot wind according to the winding path and is prone to winding at the same position.

[0007] To achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0008] A permanent magnet motor winding device, comprising a bottom plate, a transfer seat fixedly installed on the bottom plate, a transfer slot opened on the transfer seat, a rotating disk with a circular hole in the center rotatably installed in the transfer slot, a fixed column fixedly installed on the rotating disk, a fixed shaft fixedly installed at the end of the fixed column, a rotating roller for winding and unwinding copper wire rotatably installed on the fixed shaft, and a wire releasing mechanism arranged on the fixed column for taking in and releasing the copper wire on the rotating roller;

[0009] A number of fixed teeth are arranged on the outer side of the rotating disk, a driving gear meshing with the fixed teeth is rotatably installed in the transfer seat, a driving motor is fixedly installed on the back of the transfer seat, an output shaft of the driving motor is fixedly connected with the driving gear, a positioning convex column is fixedly installed in the transfer slot of the transfer seat, an annular positioning groove adapted to the positioning convex column is opened on the back of the rotating disk, fixing plates and movable seats are arranged on the front and back sides of the transfer seat on the bottom plate, a winding mechanism and a driving component for driving the winding mechanism to move back and forth are arranged between the fixing plate and the movable seat, and the winding mechanism and the wire releasing mechanism are located on the same side of the rotating disk.

[0010] Through the above technical solution, when the driving motor drives the rotating disk to rotate and the wire releasing mechanism winds the copper wire on the rotating roller around the winding mechanism, the driving component drives the winding mechanism to move back and forth, so that the position of the winding mechanism can be adjusted, and then the copper wire can be wound according to the winding path, avoiding the copper wire being wound at the same position and affecting the quality of the wound coil.

[0011] In a possible implementation manner, the winding mechanism includes two sleeves symmetrically and fixedly installed on the front surface of the fixing plate, a movable guide rail, a limiting rod horizontally fixedly installed in the movable guide rail, two movable blocks movably installed on the limiting rod, and two winding cylinders. The ends of the two sleeves pass through the circular hole in the center of the rotating disk. Two inserting rods are fixedly installed on the back of the movable guide rail, and the two inserting rods are respectively movably inserted into the two sleeves. The two movable blocks are slidably installed in the movable guide rail, and the two winding cylinders are respectively fixedly installed at the ends of the two movable blocks.

[0012] Through the above technical solution, when the rotating disk rotates, the two winding cylinders can wind the copper wire to wind a coil of the required specification.

[0013] In a possible implementation, a fixed guide rail is fixedly installed on the back of the movable seat. A bidirectional threaded rod is horizontally rotatably installed in the fixed guide rail. Two driving blocks are threadedly connected to two opposite threads of the bidirectional threaded rod. The two driving blocks are slidably installed in the fixed guide rail. Extension rods are fixedly installed on the backs of the two driving blocks. The two extension rods respectively penetrate into the interiors of the two wire reels. A first motor is fixedly installed on the fixed guide rail. The output shaft of the first motor penetrates the fixed guide rail and is fixedly connected to one end of the bidirectional threaded rod.

[0014] Through the above technical solution, when the first motor works, it drives the bidirectional threaded rod to rotate, which can drive the two driving blocks to move towards or away from each other inside the fixed guide rail. Then, the distance between the two wire reels is adjusted through the extension rods, and coils of different sizes can be wound.

[0015] In a possible implementation, the driving assembly includes a reciprocating lead screw, a shuttle slidably installed on the reciprocating lead screw, and a connecting rod fixedly installed between the shuttle and the movable guide rail. A first gear is fixedly installed at one end of the reciprocating lead screw, and a swivel joint is fixedly installed at the other end. A groove adapted to the swivel joint is formed on the fixed plate. An installation rod is fixedly installed on the fixed plate. The end of the installation 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 disc.

[0016] Through the above technical solution, when the rotating disc rotates one circle and the copper wire winds one circle on the two wire reels, the arc-shaped rack will drive the reciprocating lead screw to rotate through the first gear, thereby pushing the shuttle, the connecting rod and the movable guide rail to move, and the positions of the two wire reels can be adjusted, so that the copper wire in the next circle can naturally transition to a position adjacent to the copper wire in the previous circle, avoiding the problem that the copper wire is wound at the same position on the wire reel.

[0017] In a possible implementation, the wire releasing mechanism includes a fixed block with an installation cavity inside, two wire releasing wheels rotatably installed in the installation cavity, two second gears respectively fixedly installed on the two wire releasing wheels, and a second motor fixedly installed on the fixed block. A bent rod is fixedly installed on the fixed column. The fixed block is fixedly installed on the bent rod. Annular grooves are formed in the middle parts of the two wire releasing wheels. A plurality of first anti-slip strips are fixedly installed at equal intervals in the annular grooves. A through groove is formed on the fixed block. The copper wire on the rotating roller passes through the through groove and between the two wire releasing wheels. The two second gears are meshed with each other. The output shaft of the second motor is fixedly connected to one of the second gears.

[0018] Through the above technical solution, when the second motor works, it will release the copper wire through the wire releasing wheels, and the two wire releasing wheels will clamp the passing copper wire. When winding the coil, the copper wire will be tightened, so that the wound coil is more compact.

[0019] In a possible implementation, a dovetail groove is formed on the bottom 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 bottom plate. A rotating handle is rotatably installed on the fixing rod. A threaded rod is fixedly installed at the end of the rotating handle. A threaded seat threadedly connected to the threaded rod is fixedly installed on the movable seat.

[0020] Through the above technical solution, by rotating the rotating handle to rotate the threaded rod, a driving force can be generated on the movable seat. The fixing strip at the lower end of the movable seat is limited by the dovetail groove. When the movable seat is stressed, the movable seat will move along the direction of the dovetail groove, and the position of the movable seat can be adjusted.

[0021] In a possible implementation, a plurality of card slots are formed on the winding cylinder. Positioning pieces are movably clamped in the plurality of card slots. A compression spring is fixedly installed between the positioning piece and the slot wall of the card slot.

[0022] Through the above technical solution, the positioning piece can limit the coil to prevent the copper wire from unwinding from the winding cylinder and affecting the coil winding process.

[0023] In a possible implementation, a plurality of second anti-slip strips are provided on the positioning piece. The plurality of second anti-slip strips are arranged at equal intervals along the length direction of the positioning piece.

[0024] Through the above technical solution, the contact area and frictional resistance are increased to prevent the copper wire from slipping out of or shifting in the card slot during the winding process.

[0025] In a possible implementation, the movable guide rail and the fixed guide rail have the same length, and the length is less than the diameter of the circular hole on the rotating disc.

[0026] Through the above technical solution, when the two winding cylinders move between the movable guide rail and the fixed guide rail, they will not hinder the movement of the rotating disc and the structures on the rotating disc.

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

[0028] Through the above technical solution, by increasing the roughness of the contact surface, it can effectively prevent the copper wire from shifting or loosening due to sliding during the winding process, and ensure the uniformity and stability of the winding.

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

[0030] 1. In the present invention, when the driving motor drives the rotating disk to rotate through the driving gear, so that the wire feeding mechanism winds the copper wire on the rotating roller around the winding mechanism, the driving assembly drives the winding mechanism to move forward and backward, and the position of the winding mechanism can be adjusted, so that the copper wire is wound according to the winding path, avoiding winding the copper wire at the same position and affecting the quality of the wound coil.

[0031] 2. In the present invention, when the first motor works, it drives the bidirectional threaded rod to rotate, which can drive the two driving blocks to move towards or away from each other inside the fixed guide rail, and then adjust the distance between the two winding cylinders through the extension rod, so that coils of different sizes can be wound.

[0032] 3. In the present invention, when the rotating disk rotates one circle, the arc-shaped rack drives the first gear and the reciprocating lead screw to rotate, and the shuttle moves on the reciprocating lead 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 cylinder and receiving the copper wire released from the wire feeding mechanism. During this process, the shuttle moves reciprocally, so that the wound coil on the winding cylinder can be wound closely on the previous coil, and the winding is more compact.

[0033] 4. In the present invention, when the second motor works, it will release the copper wire through the wire feeding wheel, and the two wire feeding wheels will clamp the passing copper wire. When winding the coil, the copper wire will be tightened, so that the wound coil is more compact. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and should not be construed as a limitation to the present invention. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0066] Such as Figures 1 to 13As shown in the figure, a winding device for a permanent magnet motor of the present invention includes a bottom plate 1. A transfer seat 2 is fixedly installed on the bottom plate 1. A transfer groove is provided on the transfer seat 2. A rotating disk 21 with a circular hole in the center is rotatably installed in the transfer groove. A fixed column 22 is fixedly installed on the rotating disk 21. A fixed shaft 23 is fixedly installed at the end of the fixed column 22. A rotating roller 24 for winding and unwinding copper wire is rotatably installed on the fixed shaft 23. The end of the fixed shaft 23 passes through the center of the rotating roller 24, and a locking bolt is threadedly connected to the end protruding from the rotating roller 24. It is convenient to disassemble and assemble the rotating roller 24 through the locking bolt. A wire releasing mechanism is provided on the fixed column 22 to wind and unwind the copper wire on the rotating roller 24.

[0067] A number of fixed teeth are provided on the outer side of the rotating disk 21. A driving gear 25 meshing with the fixed teeth is rotatably installed in the transfer seat 2. A driving motor 26 is fixedly installed on the back of the transfer seat 2. The output shaft of the driving motor 26 is fixedly connected to the driving gear 25. A positioning convex column 27 is fixedly installed in the transfer groove of the transfer seat 2. An annular positioning groove adapted to the positioning convex column 27 is provided on the back of the rotating disk 21. The positioning convex column 27 extending into the annular positioning groove can prevent the rotating disk 21 from disengaging from the transfer groove. Fixing plates 3 and movable seats 4 are provided on the front and rear sides of the transfer seat 2 on the bottom plate 1. A winding mechanism and a driving component for driving the winding mechanism to move back and forth are provided between the fixing plate 3 and the movable seat 4. The winding mechanism and the wire releasing mechanism are located on the same side of the rotating disk 21.

[0068] Through the above technical solution, when the driving motor 26 drives the rotating disk 21 to rotate through the driving gear 25, and the wire releasing mechanism winds the copper wire on the rotating roller 24 around the winding mechanism, the driving component drives the winding mechanism to move back and forth, so that the position of the winding mechanism can be adjusted, and then the copper wire can be wound according to the winding path, avoiding winding the copper wire at the same position and affecting the quality of the wound coil.

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

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

[0071] In a possible embodiment, the wire winding mechanism includes two sleeves 31 symmetrically and fixedly mounted on the front surface of the fixing plate 3, a movable guide rail 32, a limiting rod 33 horizontally and fixedly mounted inside the movable guide rail 32, two movable blocks 34 movably mounted on the limiting rod 33, and two wire winding cylinders 35. When the first motor 45 operates, 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, and then adjust the distance between the two wire winding cylinders 35 through the extension rods 44, so as to wind coils of different sizes. The ends of the two sleeves 31 pass through the circular holes at the center of the rotating disc 21. Two inserting rods 321 are fixedly mounted on the back surface of the movable guide rail 32, and the two inserting rods 321 are respectively movably inserted into the two sleeves 31. The two movable blocks 34 are slidably mounted inside the movable guide rail 32, and the two wire winding cylinders 35 are respectively fixedly mounted at the ends of the two movable blocks 34.

[0072] Through the above technical solution, when the rotating disc 21 rotates, the two wire winding cylinders 35 can wind the copper wire to wind a coil of the required specification.

[0073] A fixed guide rail 41 is fixedly mounted on the back surface of the movable seat 4. A bidirectional threaded rod 42 is horizontally rotatably mounted inside the fixed guide rail 41. Two driving blocks 43 are threadedly connected to the two opposite threads of the bidirectional threaded rod 42. The two driving blocks 43 are slidably mounted inside the fixed guide rail 41. Extension rods 44 are fixedly mounted on the back surfaces of the two driving blocks 43. The two extension rods 44 respectively penetrate into the interiors of the two wire winding cylinders 35. A first motor 45 is fixedly mounted on the fixed guide rail 41. The output shaft of the first motor 45 penetrates the fixed guide rail 41 and is fixedly connected to one end of the bidirectional threaded rod 42. The lengths of the movable guide rail 32 and the fixed guide rail 41 are the same, and both lengths are smaller than the diameter of the circular hole on the rotating disc 21.

[0074] Through the above technical solution, when the first motor 45 operates, 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, and then adjust the distance between the two wire winding cylinders 35 through the extension rods 44, so as to wind coils of different sizes.

[0075] In a possible embodiment, the driving component 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. One end of the reciprocating lead screw 5 is fixedly provided with a first gear 53, and the other end is fixedly provided with a swivel joint. A groove adapted to the swivel joint is formed on the fixing plate 3. An installation rod 36 is fixedly mounted on the fixing plate 3, and the end of the installation 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 bobbin 35 are pushed each time, which is suitable for winding coils of different specifications.

[0076] The wire pay-off mechanism includes a fixed block 6 with an installation cavity inside, two wire pay-off wheels 61 rotatably mounted in the installation cavity, two second gears 62 respectively fixedly mounted on the two wire pay-off 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. Annular grooves 611 are formed in the middle of the two wire pay-off wheels 61, and a number of first anti-slip strips 612 are fixedly mounted at equal intervals in the annular grooves 611. The first anti-slip strips 612 can increase the friction between the wire pay-off wheels 61 and the copper wire, and can tighten the copper wire during the winding process, so that the wound coil is more compact. A through groove is formed in the upper part of the fixed block 6, and the copper wire on the rotating roller 24 passes through the through groove and between the two wire pay-off wheels 61. The two second gears 62 are meshed with each other, and the output shaft of the second motor 63 is fixedly connected to one of the second gears 62.

[0077] Through the above technical solution, when the second motor 63 works, the copper wire will be released through the wire pay-off wheels 61, and the two wire pay-off wheels 61 will clamp the passing copper wire. When winding the coil, the copper wire will be tightened, so that the wound coil is more compact.

[0078] In a possible embodiment, a dovetail groove 11 is formed in the bottom plate 1. 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 bottom plate 1. 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 threadedly connected to the threaded rod 14 is fixedly installed on the movable seat 4. By rotating the rotating handle 13, the threaded rod 14 can be driven to rotate, thereby driving the movable seat 4 to move along the direction of the dovetail groove 11. A plurality of card slots 351 are formed in the winding cylinder 35. A positioning piece 352 is movably clamped in each of the plurality of card slots 351. A compression spring 353 is fixedly installed between the positioning piece 352 and the wall of the card slot 351. After the coil winding is completed, the movable seat 4 is controlled to move away from the adapter seat 2, so that the insertion rod 321 is disengaged from the winding cylinder 35. At this time, the winding cylinder 35 is in a movable state and can freely move on the movable guide rail 32, which is convenient for removing the coil on the winding cylinder 35.

[0079] A plurality of second anti-slip strips (not shown in the figure) are provided on the contact surface of the positioning piece 352. The second anti-slip strips are made of rubber material. The plurality of second anti-slip strips are arranged at equal intervals along the length direction of the positioning piece 352.

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

[0081] The usage method of the present invention is as follows:

[0082] During use, the end of the copper wire is passed through the through groove and between the two wire releasing wheels 61, and then fixed on one of the winding cylinders 35. The driving motor 26 works, and the rotating disk 21 is driven to rotate through the driving gear 25. The fixing column 22, the rotating roller 24 and the wire releasing mechanism move in a circular motion along with the rotating disk 21. At this time, the second motor 63 works, and the two wire releasing wheels 61 are driven to rotate towards each other through the two second gears 62, and the copper wire on the rotating roller 24 can be slowly released;

[0083] When the wire releasing mechanism moves in a circular motion, the copper wire can be wound around the outer sides of the two winding cylinders 35. When the rotating disk 21 rotates one week and the coils on the two winding cylinders 35 are wound one week, the arc-shaped rack 211 drives the first gear 53 to rotate, and the reciprocating lead screw 5 rotates accordingly, driving the shuttle 51, the connecting rod 52 and the movable guide rail 32 to move along the direction of the sleeve 31, so as to adjust the positions of the two winding cylinders 35. During subsequent winding, the copper wire will be wound closely against the previous coil on the two winding cylinders 35, so that the copper wire is wound according to the winding path, avoiding the problem that the copper wire is wound at the same position and affecting the coil winding.

[0084] After the coil winding is completed, turning the handle 13 can drive the threaded rod 14 to rotate, thereby driving the movable seat 4 to move outward along the direction of the dovetail groove 11, away from the adapter seat 2. The insertion rod 321 will disengage from the winding cylinder 35, making the movable block 34 on the limiting rod 33 in an active state. The winding cylinder 35 can move freely on the movable guide rail 32, facilitating the removal of the coil on the winding cylinder 35 and making it more convenient to use.
