Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology, and specifically relates to a wire winding device. Background Technology

[0002] Traditional winding devices are unsuitable for automated winding of large-sized spindles and thick-diameter wires, exhibiting the following limitations: insufficient fork movement range, making it difficult to cover large-sized stators; thicker wires require stronger tension control and a more stable winding path; and low multi-axis coordination precision leads to uneven winding or wire breakage. Furthermore, the fork telescopic mechanism does not integrate complete functional modules for multi-axis movement, wire cutting, and wire stranding. Summary of the Invention

[0003] To address the aforementioned problems, the primary objective of this invention is to provide a winding device that solves the technical problem that existing winding devices are not suitable for stators of different sizes and wire diameters.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] This invention provides a wire winding device, comprising:

[0006] frame;

[0007] The mold head, located on the frame, is used to mount the stator;

[0008] The telescopic mechanism of the flying fork is located on the frame and spaced apart from the die head. It moves and rotates relative to the die head to provide wire to the stator and wind the wire onto the stator.

[0009] The telescopic mechanism of the flying fork can move and rotate relative to the die head, ensuring that the wire is accurately delivered into the stator slot, improving winding accuracy and efficiency, and realizing automated winding of the stator.

[0010] Furthermore, the telescopic fork mechanism includes:

[0011] The wire guide structure is equipped with a wire guide groove;

[0012] The telescopic structure includes a first slide rail and a limiting groove, wherein the wire-passing structure is disposed within the first slide rail;

[0013] A support structure includes a support block and a limiting component. The support block is located on the side of the telescopic structure away from the wire-passing structure, and the limiting component is located at the rear end of the support block.

[0014] Pressure plate, connected to the support block;

[0015] When the telescopic mechanism of the flying fork needs to be locked, the limiting groove and the end of the limiting component away from the support block are limited and engaged.

[0016] When the telescopic mechanism of the flying fork needs to be unlocked, the pressure plate is used to press down and drive the support block to move the limiting component away from the limiting groove, so that the telescopic structure can move along the support block.

[0017] The telescopic fork mechanism uses wire guide and telescopic components to guide and adjust the wire. The support structure works with the pressure plate, and the limiting groove and limiting component work together to achieve quick locking or unlocking, ensuring the telescopic fork mechanism is stable during wire winding and flexible during adjustment. The limiting groove and limiting component work together to prevent the telescopic fork from accidentally shifting during wire winding, improving processing stability.

[0018] Furthermore, the telescopic fork mechanism also includes:

[0019] A first drive component is connected to the front end of the telescopic structure and is used to drive the telescopic structure to move back and forth relative to the mold head.

[0020] The second driving component is connected to the pressure plate and is used to drive the pressure plate to press down on the support block, so that the support block drives the limiting component to release the limiting engagement with the limiting groove.

[0021] The first drive component drives the telescopic mechanism of the fork to move along the first direction, precisely controlling the distance between the telescopic mechanism of the fork and the stator to adapt to stators of different sizes; the second drive component drives the pressure plate to press the support block downward along the third direction, causing the limit component to disengage from the limit groove, realizing the quick unlocking of the telescopic mechanism of the fork, which is convenient for adjusting or replacing wires; it can realize the automated control of the telescopic mechanism of the fork, reducing manual intervention and improving production efficiency.

[0022] Furthermore, the supporting structural member also includes:

[0023] The stop blocks are located on opposite sides of the support block and protrude from the side surface of the support block near the telescopic structure and bend and extend toward the telescopic structure.

[0024] A baffle is provided on opposite sides of the support block and located on the side of the baffle block away from the pressure plate.

[0025] Furthermore, it also includes:

[0026] A three-dimensional motion drive mechanism is connected to the frame and is used to drive the frame to move along one of the first direction, the second direction, and the third direction, respectively.

[0027] The three-dimensional motion drive mechanism allows the frame to move in three vertical directions, achieving multi-degree-of-freedom positioning, adapting to the winding requirements of stators of different specifications, improving the versatility and flexibility of the winding device, and making it suitable for complex winding processes such as multi-layer winding and oblique winding.

[0028] Furthermore, it also includes:

[0029] A support frame is provided on the three-dimensional motion drive mechanism, and the flying fork telescopic mechanism is provided on the support frame;

[0030] The first rotating shaft is spaced apart from the support frame and connected to the fork telescopic mechanism;

[0031] The third drive component is connected to the first rotating shaft and is used to drive the first rotating shaft to rotate the fork telescopic mechanism relative to the mold head.

[0032] The support frame integrates the telescopic flying fork mechanism and the first rotating shaft, enabling the telescopic flying fork mechanism to rotate around the first rotating shaft to achieve 360° winding, which is suitable for full-circumference winding requirements; the third drive component is used to drive the first rotating shaft to ensure that the rotation speed of the telescopic flying fork mechanism matches the winding process and improves the uniformity of winding.

[0033] Furthermore, it also includes:

[0034] A first guide rod is disposed on the support frame and extends along the second direction;

[0035] A wire-cutting assembly is spaced apart from the first guide rod and is correspondingly arranged to the telescopic mechanism of the flying fork, for cutting the stranded wire.

[0036] By arranging the wire-cutting components at intervals along the second direction and corresponding to the telescopic mechanism of the flying fork, the wire can be automatically cut after winding, reducing manual operation; the first guide rod can ensure accurate wire cutting position and avoid wire residue or waste.

[0037] Furthermore, it also includes:

[0038] The stranding mechanism includes a lifting bracket, a rotating bracket, a lifting cylinder, a rotary motor, a second rotating shaft, and a stranding rod. The lifting cylinder is located on the lifting bracket and connected to the rotating bracket, and is used to drive the rotating bracket to move along the third direction. The rotary motor is located on the rotating bracket and connected to the second rotating shaft, and the second rotating shaft is connected to the stranding rod. The rotary motor is used to drive the second rotating shaft to rotate the stranding rod.

[0039] The stranding mechanism is used to adjust the height of the stranding rod along a third direction via a lifting cylinder, and a rotary motor is used to drive the stranding rod to rotate. The stranding rod ensures that the wire is stranded evenly, preventing loosening or knotting. It is suitable for applications requiring high conductivity and tensile strength, such as high-power motors. Therefore, the stranding mechanism can pre-stretch thick-diameter wires, improving the mechanical strength after winding.

[0040] Furthermore, it also includes:

[0041] The system includes a wire protection mechanism, a wire protection motion mechanism, and a load-bearing mechanism for winding the workpiece wire, wherein the wire protection motion mechanism is connected to the wire protection mechanism, and the wire protection mechanism corresponds to the load-bearing mechanism; wherein...

[0042] The line protection mechanism includes two protective plates, which together form a semi-enclosed structure. The supporting mechanism is located within the semi-enclosed structure and is spaced apart from the protective plates. The line protection motion mechanism is used to drive the line protection mechanism to move so that the line protection mechanism is enclosed or separated from the supporting mechanism.

[0043] The two guard plates of the wire protection mechanism form a semi-enclosed structure, which protects the wire from external interference during winding and prevents the winding from becoming loose or falling off. The wire protection motion mechanism is used to drive the guard plates to open and close, which facilitates the loading and unloading of the stator and avoids the guard plates interfering with the winding process. This can improve the winding yield and reduce the risk of wire breakage or winding misalignment.

[0044] Furthermore, it also includes:

[0045] At least one wire clamping mechanism, wherein the wire clamping mechanism is adapted to the wire protection mechanism;

[0046] The wire clamping mechanism includes a wire clamping cylinder and a wire clamping plate. The wire clamping plate is connected to the wire clamping cylinder, and the wire clamping cylinder is used to drive the wire clamping plate to move along the first direction.

[0047] The wire clamping mechanism drives the wire clamping plate to clamp or release the wire in the first direction through the wire clamping cylinder, ensuring that the wire is firmly fixed at the beginning and end of the winding. The wire clamping mechanism works in conjunction with the wire protection mechanism to prevent the wire from loosening or shifting during high-speed winding.

[0048] Furthermore, it also includes:

[0049] A moving mechanism is connected to the wire clamping mechanism, and the moving mechanism is used to drive the wire clamping mechanism to move along the second direction.

[0050] By driving the wire clamping mechanism to move along the second direction through the moving mechanism, it can adapt to the stator or winding position requirements of different widths, improve the adaptability and automation of the winding device, and reduce manual adjustment time.

[0051] Compared with the prior art, the beneficial effects of this application are as follows: The winding device includes: a frame; a die head, mounted on the frame, for arranging the stator; and a telescopic fork mechanism, mounted on the frame and spaced apart from the die head, which moves and rotates relative to the die head to provide wire to the stator and wind the stator.

[0064] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0065] To achieve the above objectives, the technical solution of the present invention is as follows:

[0066] See Figures 1-11 As shown, the present invention provides a wire winding device, including: a die head 10, disposed on a frame 1, for configuring a stator; and a fork telescopic mechanism 20, spaced apart from the die head 10, which moves and rotates relative to the die head 10 to provide wire to the stator and wind the stator.

[0067] By moving and rotating the telescopic mechanism 20 relative to the die head 10, the wire is accurately fed into the stator slot, improving winding accuracy and efficiency, and realizing automated winding of the stator.

[0068] Furthermore, the telescopic fork mechanism 20 includes: a wire-passing structure 21 with a wire-passing groove 211; a telescopic structure 22 including a first slide rail 221 and a limiting groove, with the wire-passing structure 21 disposed within the first slide rail 221; a support structure 23 including a support block 231 and a limiting component 232, with the support block 231 disposed on the side of the telescopic structure 22 away from the wire-passing structure 21 and the limiting component 232 disposed at the rear end of the support block 231; and a pressure plate 24 connected to the support block 231. When the telescopic fork mechanism 20 needs to be locked, the limiting groove and the end of the limiting component 232 away from the support block 231 engage in a limiting fit. When the telescopic fork mechanism 20 needs to be unlocked, the pressure plate 24 is used to press down and drive the support block 231 to disengage the limiting component 232 from the limiting groove, allowing the telescopic structure 22 to move along the support block 231.

[0069] Furthermore, the support block 231 is provided with a mounting groove 29, and the limiting component 232 includes a movable part 234 and a positioning part 233. One end of the movable part 234 is disposed in the mounting groove 29, and the other end is connected to the positioning part 233. The movable part 234 is installed in the mounting groove 29 and fixed to the support block 231 through the mounting groove 29, which facilitates the quick replacement or maintenance of the limiting component 232. The positioning part 233 is separately connected to the movable part 234 and can be replaced individually according to the wear condition, reducing maintenance costs. The mounting groove 29 is used to guide and ensure that the movable part 234 is perpendicularly aligned with the limiting groove after installation, avoiding jamming caused by off-center loading.

[0070] Furthermore, the positioning element 233 of the limiting component 232 is a pin, and the limiting groove is a recess. A limiting groove is formed by recessing the surface of the telescopic structure 22 towards the support block 231. The positioning element 233 engages with the limiting groove, achieving a limiting fit between the telescopic structure 22 and the support block 231. The engagement of the pin with the limiting groove ensures horizontal limiting between the support structure 23 and the telescopic structure 22, preventing the telescopic structure 22 from moving back and forth and ensuring no relative displacement of the telescopic fork mechanism 20 in the locked state.

[0071] By dividing the telescopic fork mechanism 20 into a wire-passing structure 21 and a telescopic structure 22, wire guiding and telescopic adjustment are achieved. The support structure 23 cooperates with the pressure plate 24, and the limiting groove and the limiting component 232 can achieve quick locking or unlocking, ensuring that the telescopic fork mechanism 20 is stable during wire winding and flexible during adjustment. The limiting groove and the limiting component 232 cooperate to prevent the telescopic fork mechanism 20 from accidentally shifting during wire winding, thus improving processing stability.

[0072] Furthermore, the telescopic mechanism 20 also includes: a first drive assembly 25 connected to the front end of the telescopic structure 22, used to drive the telescopic structure 22 to move back and forth relative to the die head 10; and a second drive assembly 26 connected to the pressure plate 24, used to drive the pressure plate 24 to press down the support block 231, so that the support block 231 drives the limiting assembly 232 to release the limiting engagement with the limiting groove.

[0073] Furthermore, the support structure 23 also includes a stop 27, which is disposed on opposite sides of the support block 231 and protrudes from the side surface of the support block 231 near the telescopic structure 22 and bends and extends toward the telescopic structure 22.

[0074] Furthermore, the support structure 23 also includes a baffle 28, which is disposed on the support block 231 and located on the side of the block 27 away from the pressure plate 24.

[0075] Furthermore, sliding grooves 222 are provided on opposite sides of the telescopic structure 22. One end of the sliding groove 222 extends through the front end of the telescopic structure 22, and the other end extends to the rear end of the telescopic structure 22 and forms a retaining wall. The end of the stop block 27 away from the support block 231 is slidably engaged with the sliding groove 222. The baffle 28 is used to limit the telescopic structure 22 to be in a first extreme position, which is the relative support of the telescopic structure 22.

[0076] Physical positioning is achieved by the collision between the stop 27 and the retaining wall at the rear end of the sliding groove 222, limiting the first extreme position of the telescopic structure 22 and ensuring high positioning accuracy. When the stop 27 moves within the sliding groove 222, it provides lateral guidance to prevent the telescopic structure 22 from swaying. The retaining wall prevents the stop 27 from disengaging from the sliding groove 222, so that even if the drive component fails, the telescopic structure 22 will not completely detach.

[0077] Furthermore, the telescopic mechanism of the flying fork proposed in this application also includes an elastic element (not shown), which is disposed in the sliding groove 222, with one end abutting against the baffle 28 and the other end abutting against the retaining wall.

[0078] By providing an elastic element in the sliding groove 222 of the telescopic structure 22, and having the elastic element abut against the stop block 27 and the retaining wall, the telescopic structure 22 achieves progressive braking relative to the supporting structure 23.

[0079] The first drive assembly 25 drives the telescopic fork mechanism 20 to move along a first direction, precisely controlling the distance between the telescopic fork mechanism 20 and the stator to adapt to stators of different sizes. The second drive assembly 26 drives the pressure plate 24 to press the support block 231 downward along a third direction, causing the limiting assembly 232 to disengage from the limiting groove, thus quickly unlocking the telescopic fork mechanism 20 for easy adjustment or replacement of wire. This allows for automated control of the telescopic fork mechanism 20's extension and locking, reducing manual intervention and improving production efficiency. Therefore, the telescopic fork mechanism 20 integrates extension, locking, and automatic unlocking functions. The first drive assembly 25 enables axial movement of the telescopic fork mechanism 20 relative to the die head 10, while the second drive assembly 26, in conjunction with the pressure plate 24, enables rapid unlocking.

[0080] Furthermore, the winding device of this application also includes a three-dimensional motion drive mechanism 30, used to drive the winding device to move along a first direction, a second direction, and a third direction respectively. Any two of the first direction, the second direction, and the third direction intersect perpendicularly. The first direction is the direction in which the telescopic mechanism 20 points towards the die head 10, that is, the forward and backward movement direction of the winding device is the first direction; the third direction is the vertical direction of the pressure plate 24 relative to the support block 231, that is, the vertical movement direction of the winding device is the third direction; and the second direction is the left and right movement direction of the winding device.

[0081] The frame 1 can move in three vertical directions through the three-dimensional motion drive mechanism 30, realizing multi-degree-of-freedom positioning, adapting to the winding requirements of stators of different specifications, improving the versatility and flexibility of the winding device, and is suitable for complex winding processes such as multi-layer winding and oblique winding.

[0082] Furthermore, the winding device of this application also includes: a support frame 31, disposed on the side of the three-dimensional motion drive mechanism 30 away from the frame 1, and a fork telescopic mechanism 20 disposed on the support frame 31; a first rotating shaft 32, spaced apart from the support frame 31, and connected to the fork telescopic mechanism 20; and a third drive assembly (not shown), connected to the first rotating shaft 32, for driving the first rotating shaft 32 to drive the fork telescopic mechanism 20 to rotate relative to the die head 10.

[0083] The fly fork telescopic mechanism 20 and the first rotating shaft 32 are integrated through the support frame 31, allowing the fly fork telescopic mechanism 20 to rotate around the first rotating shaft 32, achieving 360° winding and suitable for full-circumference winding requirements. The third drive component drives the first rotating shaft 32, ensuring that the rotation speed of the fly fork telescopic mechanism 20 matches the winding process and improving winding uniformity. Thus, through the linkage between the three-dimensional motion drive mechanism 30 and the first rotating shaft 32, multi-degree-of-freedom precise positioning of the fly fork telescopic mechanism 20 can be achieved, that is, one of the following positioning relative to the die head 10: front-back positioning, left-right positioning, and up-down positioning, adapting to the winding requirements of stators of different sizes.

[0084] Furthermore, the winding device of this application also includes: a winding mechanism 40, comprising a lifting bracket 41, a rotating bracket 42, a lifting cylinder 43, a rotary motor 44, a second rotating shaft 45, and a winding rod 46. The lifting cylinder 43 is located on the lifting bracket 41 and connected to the rotating bracket 42, and is used to drive the rotating bracket 42 to move in a third direction. The rotary motor 44 is located on the rotating bracket 42 and connected to the second rotating shaft 45, which is connected to the winding rod 46. The rotary motor 44 is used to drive the second rotating shaft 45 to rotate the winding rod 46. This winding rod 46 is more efficient during production and assembly; whether the winding rod 46 rotates clockwise or counterclockwise, it can meet more usage requirements and is more convenient to use. Therefore, the winding mechanism 40 can pre-twist thicker wires, which can improve the winding strength.

[0085] The stranding mechanism 40 is used to adjust the height of the stranding rod 46 along a third direction via the lifting cylinder 43, and the rotary motor 44 is used to drive the stranding rod 46 to rotate. The stranding rod 46 is used to ensure that the wire is stranded evenly and to avoid loosening or knotting. It is suitable for applications requiring high conductivity and tensile strength, such as high-power motors. Therefore, the stranding mechanism 40 can pre-stretch thick-diameter wires to improve the mechanical strength after winding.

[0086] Furthermore, the winding device of this application also includes: a wire protection mechanism 50 and a carrying mechanism for winding the workpiece wire, wherein the wire protection mechanism 50 and the carrying mechanism are correspondingly arranged; wherein, the wire protection mechanism 50 includes two guard plates 51, the two guard plates 51 enclosing to form a semi-enclosed structure, the carrying mechanism is disposed within the semi-enclosed structure, and the carrying mechanism and the guard plates 51 are spaced apart from each other. The wire protection mechanism 50 includes a guard plate front-to-back drive mechanism 52, a guard plate up-and-down drive mechanism (not shown), and a wire protection up-and-down drive mechanism (not shown), the guard plate front-to-back drive mechanism 52 is used to drive the guard plates 51 to move back and forth, the guard plate up-and-down drive mechanism is used to drive the guard plates 51 to move up and down, and the wire protection up-and-down drive mechanism is used to drive the entire wire protection mechanism 50 to move up and down, so that the wire protection mechanism 50 is enclosed or separated from the carrying mechanism.

[0087] Furthermore, the wire winding device of this application also includes: at least one set of wire clamping mechanisms 60, which are adapted to the wire protection mechanism 50; the wire clamping mechanism 60 includes a wire clamping cylinder 61 and a wire clamping plate 62, the wire clamping plate 62 is connected to the wire clamping cylinder 61, and the wire clamping cylinder 61 is used to drive the wire clamping plate 62 to move along a first direction, that is, the wire clamping cylinder 61 is used to drive the wire clamping plate 62 to move back and forth.

[0088] The wire clamping mechanism 60 drives the wire clamping plate 62 to clamp or release the wire in the first direction through the wire clamping cylinder 61, ensuring that the wire is firmly fixed at the beginning and end of the winding. The wire clamping mechanism 60 works in conjunction with the wire protection mechanism 50 to prevent the wire from loosening or shifting during high-speed winding.

[0089] Furthermore, the winding device of this application also includes: a moving mechanism 70, which is connected to the wire clamping mechanism 60. The moving mechanism 70 is used to drive the wire clamping mechanism 60 to move in the second direction, that is, the moving mechanism 70 is used to drive the wire clamping mechanism 60 to move left and right.

[0090] By driving the wire clamping mechanism 60 to move along the second direction through the moving mechanism 70, it can adapt to the stator or winding position requirements of different widths, improve the adaptability and automation of the winding device, and reduce manual adjustment time.

[0091] Furthermore, the winding device of this application also includes: a first guide rod 81, disposed on the support frame 31 and extending along the second direction; and a wire cutting assembly 8, spaced apart from the first guide rod 81 and correspondingly disposed to the fork telescopic mechanism 20, for cutting the wire after winding.

[0092] The wire cutting components 8 are arranged at intervals along the second direction and are correspondingly set with the telescopic mechanism 20 of the flying fork. The wire can be automatically cut after the wire is wound, reducing manual operation. The first guide rod 81 can ensure that the wire cutting position is accurate and avoid wire residue or waste.

[0093] Therefore, this winding device uses a die head 10 mounted on the frame 1 to accommodate stators of different specifications. A telescopic fork mechanism 20 is spaced apart from the die head 10, moving and rotating relative to the die head 10 to supply wire to the stator and wind it. This winding device solves the positioning problem of stator winding and forms a complete winding system suitable for winding large stators such as motor rotors and transformer coils with thick wire diameters. The telescopic fork mechanism 20 can move and rotate relative to the die head, ensuring accurate wire delivery to the stator slots, improving winding accuracy and efficiency, and achieving automated stator winding. The telescopic fork mechanism 20 and the die head 10 are relatively adjustable, adapting to stators of different sizes and wire diameters. Through a multi-axis drive system and functional module integration, the automated winding problem for large stators and thick wire diameter products is solved.

[0094] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
