Description

Technical Field

[0001] This application relates to the technical field of enameled wire production, and particularly relates to an automatic coil-changing and tail-wire leaving device for enameled wire. Background Art

[0002] Enameled wire is a wire with an insulating paint coating, which is widely used in various products such as motors and electrical appliances. During the production process of enameled wire, it is often necessary to wind it to meet the requirements of subsequent processing and use.

[0003] When changing coils in traditional enameled wire winding devices, manual operation is usually used to leave the tail wire. In this process, the operator needs to manually leave a part of the enameled wire while the take-up reel is rotating at high speed, so that downstream customers can conduct inspections. Specifically, when operating, the staff needs to judge the leaving length based on experience, and then wind and fix the enameled wire on the take-up reel to complete the winding process of the enameled wire.

[0004] In view of the above related technologies, the method of manual coil-changing and tail-wire leaving has many drawbacks. Since the take-up reel rotates at a relatively high speed, if the operator is slightly careless during manual operation, it is very easy to be cut by the high-speed rotating take-up reel, posing a serious safety hazard. Moreover, it is difficult to accurately control the length of the manually left tail wire, and the operation efficiency is low, which is difficult to meet the requirements of large-scale production. Summary of the Invention

[0005] In order to automatically and efficiently leave the tail wire during the coil-changing process, this application provides an automatic coil-changing and tail-wire leaving device for enameled wire.

[0006] An automatic coil-changing and tail-wire leaving device for enameled wire provided by this application adopts the following technical solutions:

[0007] An automatic coil-changing and tail-wire leaving device for enameled wire includes:

[0008] A frame;

[0009] A take-up assembly, two groups of which are arranged at intervals, and the take-up assembly is installed on the frame, and the take-up assembly is used for winding enameled wire;

[0010] A pay-off assembly, which is installed on the frame, and the pay-off assembly is used for evenly winding the enameled wire on the take-up assembly;

[0011] A coil-changing assembly, which is installed on the frame, and the coil-changing assembly is used for switching the take-up assembly with an empty coil when the winding is full;

[0012] Among them, the coil changing assembly includes a wire passing part, a tail wire reservation part and a wire breaking part. The wire passing part is installed on the frame and is used for moving the enameled wire. The tail wire reservation part is installed on the wire winding assembly and is used for reserving a part of the tail wire. The wire breaking part is installed on the wire winding assembly and is used for cutting off the enameled wire.

[0013] By adopting the above technical solution, during the winding process of the enameled wire, the wire paying-off assembly winds the enameled wire evenly on the wire winding assembly. When one of the wire winding discs in the wire winding assembly is fully wound, the coil changing assembly starts to work. The wire passing part can move the enameled wire to the wire winding assembly with an empty disc to ensure the continuous winding of the enameled wire. The tail wire reservation part can automatically reserve a part of the tail wire according to the setting to meet the detection requirements of downstream customers without manual operation. The wire breaking part cuts off the enameled wire at an appropriate time to complete the coil changing process, realizing the automatic tail wire reservation operation of enameled wire coil changing and avoiding the safety hazards of manual operation under high-speed wire winding discs, improving the production efficiency and meeting the requirements of large-scale production.

[0014] Optionally, the wire winding assembly includes:

[0015] A supporting disc, which is slidably installed on the frame;

[0016] A winding motor, the fixed end of which is fixedly installed on the supporting disc;

[0017] A wire winding disc, which is rotatably installed on the supporting disc. One end of the wire winding disc close to the supporting disc is coaxially and fixedly connected to the output end of the winding motor, and the wire winding disc is coaxially arranged through the supporting disc;

[0018] A winding roller, which is sleeved on the wire winding disc and is slidably connected to the wire winding disc, and the sliding direction is along the axis direction of the wire winding disc.

[0019] By adopting the above technical solution, the wire winding assembly can efficiently and stably complete the winding work of the enameled wire. The supporting disc enables the whole wire winding assembly to move flexibly according to needs to adapt to different working conditions. The winding motor makes the wire winding disc rotate evenly to ensure that the enameled wire is wound neatly and tightly on the winding roller. The winding roller provides a carrier for the enameled wire to facilitate the winding and storage of the enameled wire. When the wire winding disc rotates driven by the winding motor, the enameled wire will be wound on the winding roller orderly, which is convenient for subsequent storage, transportation and use. The wire winding assembly improves the winding efficiency and quality of the enameled wire and reduces the need for manual intervention.

[0020] Optionally, a sliding groove is formed on the frame, and the wire passing part includes:

[0021] A rewinding motor, the fixed end of the rewinding motor is fixedly installed on the frame;

[0022] A rotating frame, one end of the rotating frame is fixedly connected to the output end of the rewinding motor;

[0023] An arc-shaped rack, the arc-shaped rack is fixedly installed on the frame;

[0024] A first gear, the first gear meshes with the arc-shaped rack, and the first gear is rotatably connected to the middle section of the rotating frame;

[0025] A second gear, the second gear meshes with the first gear, and the second gear is rotatably connected to the end of the rotating frame away from the rewinding motor;

[0026] A rotating arm, one end of the rotating arm is fixedly connected to the second gear, and the rotating arm is slidably arranged in the sliding groove;

[0027] A wire guiding roller, the wire guiding roller is rotatably installed at the end of the rotating arm away from the second gear.

[0028] By adopting the above technical solutions, when the rewinding motor starts, it drives the rotating frame to rotate. The first gear rolls along the arc-shaped rack, and the first gear drives the second gear to rotate. The rotation of the second gear will drive the rotating arm to slide in the sliding groove while rotating itself. As the rotating arm slides, the wire guiding roller will also move accordingly, so that the enameled wire can be accurately moved to the take-up assembly of the empty spool under the guidance of the wire guiding roller, realizing the switching of the enameled wire between different take-up spools and improving the efficiency of enameled wire rewinding.

[0029] Optionally, a wire inlet groove is opened on the support disc, and the tail wire reservation part includes:

[0030] A cushion disc, the cushion disc is coaxially sleeved on the take-up spool and is slidably connected to the take-up spool, and the sliding direction is along the axis direction of the take-up spool. A reserved winding groove is circumferentially opened on the side wall of the cushion disc. Wire passing grooves are circumferentially spaced on the cushion disc. A placement groove is opened on the cushion disc, and the placement groove matches the winding roller;

[0031] A wire guiding block, the wire guiding block is fixedly installed on the support disc and is located at the wire inlet groove.

[0032] By adopting the above technical solutions, the wire inlet groove opened on the support disc, combined with the wire guiding block located here, can guide the enameled wire, so that the enameled wire can accurately change the spool and enter the subsequent winding process. The reserved winding groove on the side wall of the cushion disc provides a winding space for the tail wire, and the enameled wire can be wound in the reserved winding groove according to the setting, realizing the accurate reservation of the tail wire.

[0033] The wire trough facilitates the smooth entry of the enameled wire into the winding roller after leaving the reserved tail wire, avoiding jamming or chaotic winding. The placement groove on the cushion plate that matches the winding roller can ensure the relative position between the cushion plate and the winding roller, guaranteeing a smooth transition of the enameled wire from the reserved winding groove to the winding roller and accurately and efficiently completing the reservation of the enameled wire tail wire.

[0034] Optionally, the wire-breaking part includes:

[0035] Hinge blocks, two hinge blocks are symmetrically arranged, and one end of the two hinge blocks is simultaneously hinged on the wire-receiving disc, and a chute is opened on the hinge block;

[0036] Blades, the blades are fixedly installed on one side where the two hinge blocks are close to each other;

[0037] Push blocks, both ends of the push blocks are slidably installed in the chutes.

[0038] By adopting the above technical solution, during the process of changing the disc, the enameled wire enters between the two hinge blocks under the action of the wire guiding roller, and then pushes the push blocks, causing the push blocks to move in the chutes. The movement of the push blocks will drive the two hinge blocks to rotate around the hinge points, making the two hinge blocks approach each other. As the hinge blocks rotate, the blades will gradually approach and finally cut off the enameled wire. The wire-breaking part can quickly cut off the enameled wire at the appropriate time, ensuring the smooth progress of the automatic disc-changing and tail-wire-reserving operation of the enameled wire. Compared with manually cutting the enameled wire, this wire-breaking part avoids the safety hazards of manual operation under high-speed operation, and reliably and efficiently completes the cutting work of the enameled wire.

[0039] Optionally, the wire-feeding assembly includes:

[0040] A wire-feeding motor, the fixed end of the wire-feeding motor is fixedly installed on the frame;

[0041] A reciprocating lead screw, the reciprocating lead screw is rotatably installed on the frame, and one end of the reciprocating lead screw is coaxially and fixedly connected to the output end of the wire-feeding motor;

[0042] A mounting bracket, the mounting bracket is threadedly connected to the reciprocating lead screw, and the side of the mounting bracket close to the frame abuts against the frame;

[0043] A wire-feeding disc, the wire-feeding disc is hinged on the mounting bracket, and the enameled wire is wound around the wire-feeding disc.

[0044] By adopting the above technical solution, the wire pay-off motor drives the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw can be converted into the linear motion of the mounting bracket along the axis direction of the reciprocating lead screw, thereby driving the wire pay-off reel to reciprocate on the machine frame, ensuring that the enameled wire can be evenly released from the wire pay-off reel, effectively avoiding the problems of winding or accumulation of the enameled wire during the wire pay-off process. At the same time, by controlling the rotation speed and direction of the wire pay-off motor, the moving speed and direction of the wire pay-off reel can be flexibly adjusted, and then the wire release speed and winding method of the enameled wire can be accurately controlled according to the actual production requirements, improving the automation degree and production efficiency of the enameled wire production.

[0045] Optionally, a moving component is installed on the machine frame. The moving components and the wire take-up components are in one-to-one correspondence. The moving component includes:

[0046] A cylinder, the fixed end of the cylinder is fixedly connected to the machine frame;

[0047] A lifting gripper, one end of the lifting gripper is fixedly connected to the moving end of the cylinder, and the other end of the lifting gripper abuts against the bottom of the support disk.

[0048] By adopting the above technical solution, the moving component can accurately and efficiently adjust the position of the wire take-up component. When the cylinder is started, the moving end extends or retracts, driving the lifting gripper to act, so that the support disk is lifted upward or moved downward, thereby changing the starting position of the wire arrangement, and further changing the reserved length of the tail wire during the winding process, providing strong support for the smooth operation of the tail wire operation for automatic coil change of the enameled wire, and effectively improving the operation flexibility of the equipment.

[0049] Optionally, a maintenance opening is provided on the machine frame.

[0050] By adopting the above technical solution, it is convenient to maintain and repair the internal structure of the equipment. The maintenance personnel can directly reach the key parts inside the equipment through the maintenance opening, thereby shortening the maintenance time, reducing the production loss caused by equipment shutdown, and improving the maintenance efficiency.

[0051] Optionally, the wire guiding roller is a cylindrical roller with a tapered end.

[0052] By adopting the above technical solution, when the enameled wire moves on the wire guiding roller, the tapered part can guide the enameled wire to accurately move to the appropriate position of the wire guiding roller, preventing the enameled wire from shifting, getting off the line, etc. during the movement, and helping to improve the transmission stability of the enameled wire during the coil change process.

[0053] Optionally, a control console is installed on the machine frame. The winding motor, the coil change motor, the wire pay-off motor and the cylinder are all electrically connected to the control console.

[0054] By adopting the above technical solution, operators can centrally control each motor and cylinder through the console, achieving precise setting and real-time adjustment of the equipment operation parameters, greatly improving the operation convenience, operation stability, and production process controllability.

[0055] In summary, the present application includes at least one of the following beneficial technical effects:

[0067] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0068] The following Figures 1-6 will further elaborate on the present application in detail.

[0069] The embodiment of the present application discloses an automatic wire reel changing and tail wire leaving device for enameled wires.

[0070] Referring to Figure 1 , the automatic wire reel changing and tail wire leaving device for enameled wires includes a frame 1, a wire winding assembly 2, a wire feeding assembly 3, a reel changing assembly 4, and a moving assembly 5. There are two groups of wire winding assemblies 2 arranged at intervals. The wire winding assembly 2 is installed on the frame 1, and the wire winding assembly 2 is used for winding enameled wires. The wire feeding assembly 3 is installed on the frame 1, and the wire feeding assembly 3 is used for evenly winding the enameled wires on the wire winding assembly 2. The reel changing assembly 4 is installed on the frame 1, and the reel changing assembly 4 is used for switching the wire winding assembly 2 with an empty reel when the winding is full. The moving assembly 5 is installed on the frame 1, and the moving assembly 5 is used for adjusting the position of the wire winding assembly 2.

[0071] When using the automatic wire reel changing and tail wire leaving device for enameled wires, first, the enameled wires are evenly released through the wire feeding assembly 3 and wound on a group of wire winding assemblies 2. When the winding disc 23 of the wire winding assembly 2 is full, the reel changing assembly 4 works to switch the enameled wires to another group of wire winding assemblies 2 with empty reels to ensure the continuous winding of the enameled wires. During this process, the position of the wire winding assembly 2 can be adjusted through the moving assembly 5 to change the starting position of wire laying and the reserved length of the tail wire. In this way, the automatic wire reel changing and tail wire leaving operation of the enameled wires is continuously cycled, improving the production efficiency and the stability of the production process.

[0072] Referring to Figure 1, the frame 1 is composed of a bottom plate and side plates. The bottom plate is horizontally arranged, and the side plates are vertically arranged. The cross-section of the frame 1 is L-shaped. The interior of the bottom plate is a cavity, and a maintenance opening 12 is provided on the upper surface of the bottom plate.

[0073] Referring to Figure 2 and Figure 5 , each wire winding assembly 2 includes a support disk 21, a winding motor 22, a wire winding disk 23, and a winding roller 24. The support disk 21 is in a disk-shaped structure and is horizontally arranged. The support disk 21 is slidably installed on the bottom plate of the frame 1. The winding motor 22 is arranged in the cavity of the frame 1, and the fixed end of the winding motor 22 is fixedly installed on the support disk 21. The wire winding disk 23 is rotatably installed on the support disk 21. In the embodiment of the present application, a bearing 25 is provided between the wire winding disk 23 and the support disk 21. One end of the wire winding disk 23 close to the support disk 21 is coaxially and fixedly connected to the output end of the winding motor 22. The wire winding disk 23 is coaxially inserted through the support disk 21. The winding roller 24 has an I-shaped cross-section and is provided with a hole along the axial direction. The winding roller 24 is coaxially sleeved on the wire winding disk 23, and the winding roller 24 is slidably connected to the wire winding disk 23, and the sliding direction is along the axial direction of the wire winding disk 23.

[0074] When using the automatic wire changing and tail wire leaving device for enameled wires, the winding motor 22 is started. The torque generated by the winding motor 22 drives the wire winding disk 23 to start rotating around its axis. The wire winding disk 23 realizes flexible rotation through the bearing 25 provided between it and the support disk 21, ensuring the smoothness of the rotation process. The rotation of the wire winding disk 23 drives the winding roller 24 to rotate synchronously. After the enameled wire is led out from the wire releasing assembly 3, it is wound around the winding roller 24. As the wire winding disk 23 continues to rotate, the enameled wire is continuously wound onto the winding roller 24 until the winding roller 24 is fully wound with enameled wire. In the embodiment of the present application, the rotation directions of the two winding rollers 24 are opposite.

[0075] Referring to Figure 2 , the wire releasing assembly 3 includes a wire releasing motor 31, a reciprocating lead screw 32, a mounting bracket 33, and a wire releasing disk 34. The fixed end of the wire releasing motor 31 is fixedly installed on the side plate of the frame 1. The reciprocating lead screw 32 is vertically arranged and is rotatably installed on the frame 1. One end of the reciprocating lead screw 32 is coaxially and fixedly connected to the output end of the wire releasing motor 31. The mounting bracket 33 is threadedly connected to the reciprocating lead screw 32. The side of the mounting bracket 33 close to the frame 1 abuts against the frame 1. The wire releasing disk 34 is vertically arranged and is hinged to the mounting bracket 33. The enameled wire is wound around the wire releasing disk 34.

[0076] When using the automatic coil-changing and tail-wire-retaining device for enameled wire, the enameled wire produced from the previous processing station is wound around the wire-releasing reel 34. The wire-releasing motor 31 is started, and the rotation of the wire-releasing motor 31 drives the reciprocating lead screw 32 to rotate synchronously. The reciprocating lead screw 32 is in close threaded fit with the mounting frame 33, and the side of the mounting frame 33 close to the machine frame 1 is always in contact with the machine frame 1, so that the rotational motion of the reciprocating lead screw 32 is converted into a uniform linear reciprocating motion of the mounting frame 33 along the axis direction of the reciprocating lead screw 32, guiding the enameled wire to be evenly wound around the winding roller 24.

[0077] As the winding of the winding roller 24 varies, the wire-releasing reel 34 hinged on the mounting frame 33 also moves adaptively. The enameled wire wound around the wire-releasing reel 34 is guided to be evenly and neatly wound around the winding roller 24. The operator can flexibly adjust the rotation speed and direction of the wire-releasing motor 31 to precisely control the rotation speed of the reciprocating lead screw 32, and then accurately regulate the moving speed and stroke of the mounting frame 33 and the wire-releasing reel 34, ensuring that the enameled wire is evenly and accurately released from the wire-releasing reel 34 at a stable and appropriate speed, avoiding situations such as winding, knotting or loosening, and effectively guaranteeing the efficient and stable operation of the automatic coil-changing and tail-wire-retaining operation of the enameled wire.

[0078] Refer to Figure 3 、 Figure 4 and Figure 5 As shown in, the coil-changing assembly 4 includes a wire-passing part 41, a tail-wire-reserving part 42 and a wire-breaking part 43. The wire-passing part 41 is installed on the machine frame 1 and is used to make the enameled wire move between the two wire-receiving assemblies 2. There are two groups of tail-wire-reserving parts 42 corresponding to the wire-receiving assemblies 2. The tail-wire-reserving part 42 is installed on the wire-receiving assembly 2 and is used to reserve a part of the tail wire. There are two groups of wire-breaking parts 43 corresponding to the wire-receiving assemblies 2. The wire-breaking part 43 is installed on the wire-receiving assembly 2 and is used to cut off the enameled wire.

[0079] Refer to Figure 3, the wire passing part 41 includes a rewinding motor 411, a rotating frame 412, an arc-shaped rack 413, a first gear 414, a second gear 415, a rotating arm 416 and a wire passing roller 417. The fixed end of the rewinding motor 411 is fixedly installed in the cavity of the frame 1. The rotating frame 412 is horizontally arranged. One end of the rotating frame 412 is fixedly connected to the output end of the rewinding motor 411. The arc-shaped rack 413 is fixedly installed on the frame 1. The axis of the arc-shaped rack 413 coincides with the axis of the output shaft of the rewinding motor 411. The first gear 414 meshes with the arc-shaped rack 413. The rotating frame 412 is arranged in the cavity of the frame 1. The first gear 414 is rotationally connected to the middle section of the rotating frame 412. The second gear 415 meshes with the first gear 414. The second gear 415 is rotationally connected to the end of the rotating frame 412 away from the rewinding motor 411. An arc-shaped sliding groove 11 is formed on the frame 1. The shape of the sliding groove 11 matches the movement path of the second gear 415. The rotating arm 416 is horizontally arranged and located on the surface of the frame 1. One end of the rotating arm 416 is fixedly connected to the second gear 415. The rotating arm 416 is slidably arranged in the sliding groove 11. The wire passing roller 417 is rotatably installed at the end of the rotating arm 416 away from the second gear 415. The wire passing roller 417 is a cylindrical roller with tapered ends.

[0080] When using the automatic wire changing and tail wire leaving device for enameled wire, when a wire winding disc 23 is about to be fully wound with enameled wire, the wire passing part 41 of the wire changing assembly 4 starts to operate. First, the rewinding motor 411 is started. The rotation of the output shaft of the rewinding motor 411 drives the rotating frame 412 to make a circular motion around its axis. As the rotating frame 412 rotates, the first gear 414 rolls along the arc-shaped rack 413. The rolling of the first gear 414 drives the second gear 415 meshing with it to rotate at the same time. The rotation of the second gear 415 drives the rotating arm 416 to slide along a specific arc track in the sliding groove 11. At the same time, the rotating arm 416 also rotates around its own axis as the second gear 415 rotates, so that the wire passing roller 417 moves as the rotating arm 416 moves. At this time, the wire passing roller 417 can guide the enameled wire from the wire winding assembly 2 that is about to be full to the wire winding assembly 2 of the empty disc. The shape of the wire passing roller 417 makes it difficult for the enameled wire to come off the wire passing roller 417 during the process of moving the enameled wire, realizing the smooth transfer of the enameled wire between the two wire winding assemblies 2 and ensuring the continuity of the enameled wire winding work.

[0081] Refer to Figure 1 , Figure 4 and Figure 6, the tail wire reservation part 42 includes a cushion plate 421 and a wire guiding block 425. The cushion plate 421 is horizontally arranged, coaxially sleeved on the wire winding disc 23, and is slidably connected to the wire winding disc 23. The sliding direction is along the axial direction of the wire winding disc 23. The lower surface of the cushion plate 421 abuts against the wire winding disc 23. A reserved winding groove 422 is circumferentially formed on the side wall of the cushion plate 421. Four wire passing grooves 423 are circumferentially spaced on the cushion plate 421. The number of the wire passing grooves 423 can be adjusted according to the rotation speed of the wire winding disc 23 during actual use. A placement groove 424 is formed on the cushion plate 421. The shape of the placement groove 424 matches that of the winding roller 24, so that the winding roller 24 is embedded in the placement groove 424, and the upper surface of the contact part between the winding roller 24 and the cushion plate 421 is flush with the upper surface of the cushion plate 421. A wire inlet groove 211 is formed on the support plate 21. The position of the wire inlet groove 211 matches the position where the enameled wire is moved by the wire passing roller 417. The wire guiding block 425 is fixedly installed on the support plate 21 and is located at the wire inlet groove 211. The upper surface of the wire guiding block 425 should be higher than the upper surface of the support plate 21.

[0082] When the enameled wire is continuously wound on the winding roller 24 of the wire winding assembly 2 until the near full disc requires a disc change operation, the wire passing part 41 guides the enameled wire to be close to another winding roller 24. At this time, the enameled wire is guided from the wire passing roller 417 to the wire inlet groove 211 of the support plate 21. Under the guiding action of the wire guiding block 425, the enameled wire accurately enters the wire inlet groove 211, contacts the wire breaking part 43 and is clamped into the wire breaking part 43.

[0083] As the wire winding disc 23 continues to rotate, the enameled wire is wound into the reserved winding groove 422 and is wound in the reserved winding groove 422 according to the set length. As the number of winding times increases, the wire pay-off disc 34 continuously moves upward under the action of the reciprocating lead screw 32. When the winding length reaches the preset length, the enameled wire enters the winding roller 24 through the wire passing groove 423 on the cushion plate 421. Since the winding roller 24 is embedded in the placement groove 424 of the cushion plate 421 and the upper surfaces of the contact parts are flush, it ensures the smoothness of the enameled wire when transitioning from the reserved winding groove 422 to the winding roller 24. After the enameled wire transitions to the winding roller 24, it enters the normal winding state.

[0084] Refer to Figure 1 and Figure 4, the wire breakage part 43 includes a hinge block 431, a blade 433 and a push block 434. There are two symmetrically arranged hinge blocks 431. One ends of the two hinge blocks 431 are both hinged on the outer peripheral side of the wire reel 23. The opening directions of the two hinge blocks 431 are opposite to the direction of the enameled wire entering. A chute 432 is provided on the hinge block 431. The number of blades 433 corresponds to the number of hinge blocks 431 one by one. The two blades 433 are respectively fixedly installed on one sides of the two hinge blocks 431 close to each other. Both ends of the push block 434 are respectively slidably installed in the corresponding chutes 432 of the two hinge blocks 431. The shape of the chute 432 is such that when the push block 434 is pushed towards the hinge, the two hinge blocks 431 approach each other under the action of the push block 434.

[0085] During the process of changing the reel, when the wire guiding part 41 guides the enameled wire to the new wire winding assembly 2, under the action of the wire guiding block 425, the enameled wire enters from the openings of the two hinge blocks 431. As the wire reel 23 continues to move, the enameled wire will push the push block 434. The shape of the chute 432 is such that when the push block 434 is pushed towards the hinge of the hinge block 431, the two hinge blocks 431 will rotate around their hinge points with the wire reel 23 and gradually approach each other. As the hinge blocks 431 rotate, the two blades 433 will also gradually approach the enameled wire. When the hinge blocks 431 rotate to a certain extent, the two blades 433 will contact and cut off the enameled wire, thus completing the cutting operation of the enameled wire, realizing the smooth change of the wire reel 23, and ensuring the continuous progress of the automatic wire winding operation with a tail wire left during the change of the enameled wire reel.

[0086] Refer to Figure 3 , the number of the moving assemblies 5 corresponds to the number of the wire winding assemblies 2 one by one. The moving assembly 5 includes a cylinder 51 and a lifting gripper 52. The fixed end of the cylinder 51 is fixedly connected to the side plate. The lifting gripper 52 is horizontally arranged and has a Y-shaped structure. One end of the lifting gripper 52 is fixedly connected to the moving end of the cylinder 51, and the other end of the lifting gripper 52 abuts against the lower surface of the support disk 21.

[0087] When it is necessary to adjust the position of the wire winding assembly 2, for example, when it is necessary to change the starting position of the wire arrangement before and after changing the reel to adjust the length of the tail wire reserved, the moving assembly 5 starts to work. After the cylinder 51 fixedly connected to the side plate receives the control instruction, the piston inside the cylinder 51 starts to move. If the instruction is to lift the wire winding assembly 2, the moving end of the cylinder 51 retracts inward; if the instruction is to lower the wire winding assembly 2, the moving end of the cylinder 51 extends outward. When the moving end of the cylinder 51 moves, it will drive the lifting gripper 52 to move synchronously. When the moving end of the cylinder 51 retracts, the lifting gripper 52 lifts upward, and then jacks up the support disk 21, so that the whole wire winding assembly 2 rises; when the moving end of the cylinder 51 extends, the lifting gripper 52 descends, and the support disk 21 descends under the action of its own gravity, and the overall position of the wire winding assembly 2 decreases.

[0088] The moving component 5 can accurately and efficiently adjust the position of the wire take-up component 2, meet the requirements for the position of the wire take-up component 2 in different production processes, provide a strong guarantee for the smooth operation of the automatic wire-changing and tail-wire-leaving operation of the enameled wire, and improve the flexibility of the device operation.

[0089] Referring to Figure 1 and Figure 3 , a control console 6 is installed on the frame 1, and the winding motor 22, the disk-changing motor 411, the wire-releasing motor 31, and the cylinder 51 are all electrically connected to the control console 6.

[0090] During the operation of the automatic wire-changing and tail-wire-leaving device for the enameled wire, the control console 6 plays a core control hub role. Before the equipment starts, the operator sets the operation parameters of the device on the control console 6 according to the winding requirements of the enameled wire. For example, a suitable rotation speed is set for the winding motor 22 to ensure that the enameled wire can be wound tightly and evenly on the winding roller 24 of the wire take-up reel 23; for the wire-releasing motor 31, a corresponding rotation speed is set to accurately control the releasing speed of the enameled wire so that it matches the winding speed and avoid the enameled wire from being too tight or too loose.

[0091] During the disk-changing process, the operator issues an instruction through the control console 6 to start the disk-changing motor 411, driving the relevant components of the wire-passing part 41 to move, realizing the accurate movement of the enameled wire between the two wire take-up components 2. At the same time, the control console 6 can control the telescoping of the cylinder 51 according to parameters such as the preset tail-wire reserved length, and adjust the position of the wire take-up component 2.

[0092] During the entire winding process, the control console 6 monitors the operation states of the winding motor 22, the disk-changing motor 411, the wire-releasing motor 31, and the cylinder 51 in real time. Once an abnormal operation is detected, corresponding measures are taken to ensure the safe and stable operation of the equipment and the winding quality of the enameled wire.

[0093] The implementation principle of an automatic wire-changing and tail-wire-leaving device for enameled wire in an embodiment of this application is: during the operation of the automatic wire-changing and tail-wire-leaving device for enameled wire, with the frame 1 as the basic support platform, the wire-releasing component 3 is started under the control of the control console 6, and the wire-releasing motor 31 drives the reciprocating lead screw 32 to rotate, so that the wire-releasing reel 34 on the mounting bracket 33 moves along the axis of the reciprocating lead screw 32, and the enameled wire is evenly released. At the same time, the wire take-up component 2 is started synchronously, and the winding motor 22 drives the wire take-up reel 23 to rotate, winding the enameled wire on the winding roller 24.

[0094] When the winding roller 24 is about to be full, the disk-changing operation is started. The disk-changing motor 411 operates under the instruction of the control console 6, driving the rotating frame 412 to rotate, so that the first gear 414 rolls along the arc-shaped rack 413. The first gear 414 drives the second gear 415 to rotate, and then drives the rotating arm 416 to act. The wire-passing roller 417 transfers the enameled wire from the full-disk winding assembly 2 to the empty-disk winding assembly 2. The tail-wire reservation part 42 works synchronously. The enameled wire is guided by the wire guide block 425, passes through the wire groove 423 of the cushion plate 421, and completes the tail-wire winding in the reserved winding wire groove 422 according to the preset length. Under the push of the enameled wire, the breaking part 43 makes the pushing block 434 drive the hinged block 431 to rotate, so that the blade 433 cuts off the enameled wire, completing the disk-changing and tail-wire reservation.

[0095] The moving assembly 5 can, according to the instruction of the control console 6, drive the lifting gripper 52 through the cylinder 51 to adjust the position of the winding assembly 2, meet different production requirements, realize automatic disk-changing of the enameled wire while reserving the tail wire, improve the production efficiency and quality, and avoid the safety hazards of manual operation.

[0096] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
