Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and in particular to a novel winding machine. Background Technology

[0002] A winding machine is a device that winds a wire-like object onto a specific workpiece, typically used for winding copper wire. Existing winding machines usually involve first picking up the workpiece and transferring it to the winding station. Then, the winding spindle drives the winding head to wind the workpiece, while a fork arm feeds the wire to the winding head. After winding is complete, a wire-cutting mechanism cuts the wire. The wound workpiece is then transferred to a wire-pressing device to press the Y-type or μ-type pins on the workpiece. To prevent the wire end from falling out of the hanging pin or breaking off during subsequent processes or transportation, thus causing contact failure between the wire end and the hanging pin and resulting in defects, existing winding machines typically wind the workpiece first and then press the hanging pin together. This easily leads to the wire end falling out of the hanging pin during the winding process. Furthermore, winding and pressing require two different machines, resulting in higher production costs. The size and thickness of the wire used by the winding machine vary depending on the workpiece size. During winding, it is often necessary to change the wire according to requirements. Because the working principle of a winding machine requires a fork arm to supply wire to the winding head, when the winding machine is in winding mode, the end face of the fork arm is located behind the end face of the winding head to facilitate wire supply. When the winding machine is in wire changing mode, the end face of the fork arm must be located behind the end face of the winding head to allow the winding head to cooperate with the fork arm for wire changing. Existing winding machines generally use a fork arm to fix the moving winding head. The current method involves moving the winding head backward so that its front end face is behind the front end face of the fly fork arm when a wire change is needed. After the wire change is completed, the winding head is moved back to its original position so that its front end face is in front of the front end face of the fly fork arm. Since the volume of the winding head is much larger than that of the fly fork arm, a large amount of space needs to be reserved when installing the winding head, which increases the size of the winding machine and raises the assembly and operating costs. Therefore, improvements are needed. Summary of the Invention

[0003] The main objective of this invention is to propose a novel winding machine that occupies a small area and can quickly pre-press the hanging needle.

[0004] To achieve the above objectives, this invention proposes a novel winding machine, comprising a frame and a winding mechanism and a pre-pressing mechanism disposed on the frame. The frame has a winding station. The winding mechanism includes a winding assembly and a fly fork assembly. A fly fork connector is provided at the winding assembly, and the fly fork assembly is connected to the winding assembly via the fly fork connector. The winding assembly includes a winding head, and the fly fork assembly includes a fly fork arm and a fly fork drive module. The fly fork drive module includes a fly fork telescopic component and a fly fork power component. The rear end of the fly fork arm is connected to the fly fork telescopic component, and the fly fork power component... The component is connected to the telescopic component of the fly fork and pushes the telescopic component of the fly fork to extend the end face of the front end of the fly fork arm to the front side of the end face of the front end of the winding head. When the fly fork power component is not working, the telescopic component of the fly fork pulls the fly fork arm and makes the end face of the front end of the fly fork arm return to the rear side of the end face of the front end of the winding head. The pre-pressing mechanism includes a pre-pressing drive module and a presser foot assembly. One end of the presser foot assembly is provided with a pressing hole corresponding to the workpiece hanging needle. The pre-pressing drive module is connected to the presser foot assembly and drives the pressing hole to move to the winding station to press the workpiece hanging needle.

[0005] Specifically, the winding assembly further includes a winding spindle, the fly fork connector is sleeved between the winding head and the winding spindle, the winding spindle is connected to the winding head in a driving connection, and the fly fork arm is located at the fly fork connector and at the upper end of the winding head.

[0006] Specifically, the fork telescopic component includes a fork telescopic shaft and a fork limiting seat. The fork limiting seat is fixedly disposed at the fork connector. The fork telescopic shaft is movably disposed within the fork limiting seat. The rear end of the fork arm is connected to the front end of the fork telescopic shaft. A limiting groove is provided on the outer surface of the rear end of the fork telescopic shaft. A limiting waist-shaped hole is provided at the fork limiting seat. A fork limiting pin that cooperates with the limiting waist-shaped hole is provided in the limiting groove. A limiting cavity is provided inside the fork telescopic shaft. A fork tensioning pin is movably disposed in the limiting cavity. The fork tensioning pin pushes the fork limiting pin to the outside of the limiting groove, so that the fork limiting pin engages with the limiting waist-shaped hole to achieve locking between the fork telescopic shaft and the fork limiting seat.

[0007] Specifically, the fork tensioning pin includes an integrally formed locking part and a transmission part. The locking part is located at the front end of the transmission part and is located inside the limiting cavity. The rear end of the fork telescopic shaft is provided with an unlocking hole, which communicates with the limiting cavity. The transmission part extends to the outside of the limiting cavity through the unlocking hole. A first return spring is also provided inside the limiting cavity. One end of the first return spring abuts against the inner wall of the front end of the limiting cavity, and the other end of the first return spring abuts against the front end of the locking part.

[0008] Specifically, the telescopic component of the fork also includes a first reset spring, the fork limiting seat is provided with a first spring fixing hole, the front end of the telescopic shaft of the fork is provided with a second spring fixing hole, and the two ends of the first reset spring are respectively fixed to the first spring fixing hole and the second spring fixing hole by fixing screws.

[0009] Specifically, the flying fork power component includes a flying fork push cylinder, the piston rod end of the flying fork push cylinder is arranged towards the flying fork telescopic shaft, a flying fork push plate is provided at the piston rod end of the flying fork push cylinder, and a flying fork push shaft is provided on the side of the flying fork push plate facing the flying fork telescopic shaft. The flying fork push shaft is used to push the flying fork telescopic shaft and the flying fork tensioning pin.

[0010] Specifically, the pre-pressure drive module includes a pre-pressure mounting plate, a vertical pre-pressure drive cylinder, a rotary motor, and a rotary mounting base. The vertical pre-pressure drive cylinder and the rotary motor are both located on the frame. The pre-pressure mounting plate is located above the winding station. The piston rod end of the vertical pre-pressure drive cylinder is connected to the pre-pressure mounting plate and drives the pre-pressure mounting plate to move vertically. The rotary mounting base is rotatably mounted on the lower surface of the pre-pressure mounting plate. The rotary motor is connected to the rotary mounting base. The pressure foot assembly is connected to the lower surface of the rotary mounting base.

[0011] Specifically, the presser foot assembly includes a first presser arm, a second presser arm, a presser foot sleeve, and a presser foot swing arm. The first presser arm has a movable cavity, and its lower end has a connecting hole communicating with the movable cavity. The upper end of the second presser arm is movably disposed within the movable cavity through the connecting hole. A second return spring is disposed within the movable cavity; one end of the second return spring abuts against the inner wall of the upper end of the movable cavity, and the other end abuts against the upper end of the second presser arm. The lower end of the second presser arm is connected to the upper end of the presser foot sleeve. The pressing hole is located at the presser foot sleeve and extends to its lower end. The foot cover is provided with a first pivot hole, and the lower end of the presser foot swing arm is provided with a second pivot hole corresponding to the first pivot hole. A connection port is provided on one side of the presser foot cover, which communicates with the press hole. The lower end of the presser foot swing arm enters the press hole through the connection port and forms a press head that mates with the press hole. A pivot shaft is provided on the outside of the presser foot cover. The pivot shaft passes through the first pivot hole and the second pivot hole in sequence to realize the connection between the presser foot cover and the presser foot swing arm. A second return spring is connected between the outer side of the first press arm and the outer side of the presser foot swing arm. The second return spring ensures that the presser foot swing arm is always close to the first press arm.

[0012] Specifically, the middle part of the presser foot swing arm is provided with a push part, the height of which is less than the height of the first presser arm. The upper end of the push part is provided with a push surface, and the lower end of the first presser arm is provided with a force-bearing surface corresponding to the push surface. Pushing the first presser arm downward causes the force-bearing surface and the push surface to interact and move the presser foot swing arm outward, while simultaneously moving the press head in the press hole and squeezing the space at the press hole to press the external hanging needle. The push part is set on one side facing the second presser arm, and the second presser arm is provided with a clearance hole corresponding to the push part. The push surface and the force-bearing surface are both inclined at the same angle.

[0013] The technical solution of this invention sets up a winding mechanism and a pre-pressing mechanism at the frame. The winding mechanism winds the workpiece located at the winding station. During winding, the pre-pressing mechanism pre-presses the hanging pin of the workpiece at the winding station, ensuring that the wire end is stably reserved at the hanging pin, effectively preventing the wire end from falling out of the hanging pin. At the same time, the flying fork drive module drives the flying fork arm to move back and forth, allowing the end face of the front end of the flying fork arm to more flexibly move relative to the end face of the front end of the winding assembly. This enables the flying fork arm to better cooperate with the winding assembly and quickly switch between the feeding state and the changing state, thereby greatly improving the wire changing efficiency of the winding assembly and greatly reducing the footprint of the winding machine, effectively reducing the operating cost of the winding machine.

[0034] like Figures 1 to 16As shown, a novel winding machine includes a frame 100 and a winding mechanism 200 and a pre-pressing mechanism 300 disposed on the frame 100. The frame 100 has a winding station. The winding mechanism 200 includes a winding assembly 210 and a fly fork assembly 220. The winding assembly 210 has a fly fork connector 230. The fly fork assembly 220 is connected to the winding assembly 210 through the fly fork connector 230. The fly fork assembly 220 includes a fly fork arm 221 and a fly fork drive module. The fly fork drive module is hygienically connected to the fly fork arm 221 and drives the fly fork arm 221 to move back and forth in the horizontal direction toward the winding station. The pre-pressing mechanism 300 includes a pre-pressing drive module and a presser foot assembly. One end of the presser foot assembly has a pressing hole 321 corresponding to the workpiece 900 hanging needle 910. The pre-pressing drive module is hygienically connected to the presser foot assembly and drives the pressing hole 321 to move to the winding station to press the workpiece 900 hanging needle 910. When winding workpiece 900, the workpiece 900 to be wound is first placed at the winding station. The winding assembly 210 places the wire end at the hanging pin 910 of workpiece 900. The pre-pressing mechanism 300 pre-presses the hanging pin 910 of workpiece 900 to stabilize the wire end at the hanging pin 910. Then, the winding assembly 210 continues to wind workpiece 900. During the winding process, the pressing hole 321 can always press the hanging pin 910, further improving the stability of the wire end. After completing the winding of one part of workpiece 900, the pressing foot assembly can rotate with workpiece 900 through cooperation with the pre-pressing drive module. When workpiece 900 has completed rotation and needs to be wound to the next part, the pressing foot assembly again cooperates with the pre-pressing drive module to press the workpiece. The next thread-holding pin 910 of 900 is pressed together. In addition, when the winding assembly 210 needs to change the wire, the flying fork drive module drives the flying fork arm 221 to extend forward, so that the end face of the front end of the flying fork arm 221 is located in front of the end face of the front end of the winding assembly 210, which facilitates the wire change of the winding assembly 210 and greatly improves the wire change efficiency. There is no need to move the large winding assembly 210 backward, which greatly reduces the size and floor space of the winding machine and greatly saves the production and use cost of the winding machine. After the wire change is completed, the flying fork drive module drives the flying fork arm 221 to reset backward, so that the end face of the front end of the flying fork arm 221 is located in rear of the end face of the front end of the winding assembly 210, so that the flying fork arm 221 can supply wire to the winding assembly 210.

[0035] The winding assembly 210 includes a winding head 211 and a winding spindle 212. A fly fork connector 230 is sleeved between the winding head 211 and the winding spindle 212. The winding spindle 212 is connected to the winding head 211 via a drive mechanism. A fly fork arm 221 is located at the fly fork connector 230 and at the upper end of the winding head 211. The winding head 211 is driven to rotate by the winding spindle 212, thereby achieving winding of the workpiece 900. At the same time, the fly fork arm 221 supplies wire to the winding spindle 212, thereby improving the winding efficiency of the workpiece 900.

[0036] The fly fork drive module includes a fly fork telescopic component and a fly fork power component. The rear end of the fly fork arm 221 is connected to the fly fork telescopic component. The fly fork power component is connected to the fly fork telescopic component and drives the fly fork telescopic component to extend the end face of the front end of the fly fork arm 221 to the front side of the end face of the front end of the winding head 211. When the fly fork power component is not working, the fly fork telescopic component pulls the fly fork arm 221 and causes the end face of the front end of the fly fork arm 221 to return to the rear side of the end face of the front end of the winding head 211. When driving the fly fork arm 221, the fly fork power component cooperates with the fly fork telescopic component. The fly fork power component provides power to the fly fork telescopic component, causing the fly fork telescopic component to extend forward so that the fly fork arm 221 can cooperate with the winding head 211 to change the wire. After the wire changing operation is completed, the fly fork power component returns to its original position. At this time, the fly fork telescopic component loses the force from the fly fork power component and resets itself. At the same time, it drives the fly fork arm 221 to move backward so that the fly fork arm 221 can cooperate with the winding head 211 to supply wire.

[0037] The telescopic fork assembly includes a telescopic fork shaft 222 and a telescopic fork limiting seat 223. The telescopic fork limiting seat 223 is fixedly mounted on the telescopic fork connector 230. The telescopic fork shaft 222 is movably mounted within the telescopic fork limiting seat 223. The rear end of the telescopic fork arm 221 is connected to the front end of the telescopic fork shaft 222. A limiting groove 2221 is provided on the outer surface of the rear end of the telescopic fork shaft 222. A limiting oblong hole 2231 is provided at the telescopic fork limiting seat 223. The limiting groove 2221 contains a... The fork limiting pin 224 is engaged with the limiting waist-shaped hole 2231. The fork telescopic shaft 222 has a limiting cavity 2222. The fork tensioning pin 225 is movably disposed in the limiting cavity 2222. The fork tensioning pin 225 pushes the fork limiting pin 224 against the outside of the limiting groove 2221, so that the fork limiting pin 224 engages with the limiting waist-shaped hole 2231 to achieve locking between the fork telescopic shaft 222 and the fork limiting seat 223. The fork tensioning pin 225 includes an integrally formed The device comprises a locking part 2251 and a transmission part 2252. The locking part 2251 is located at the front end of the transmission part 2252 and is situated within a limiting cavity 2222. An unlocking hole 2223 is provided at the rear end of the telescopic shaft 222, communicating with the limiting cavity 2222. The transmission part 2252 extends out of the limiting cavity 2222 through the unlocking hole 2223. A first return spring 226 is also provided within the limiting cavity 2222. One end of the 6 abuts against the inner wall of the front end of the limiting cavity 2222, and the other end of the first return spring 226 abuts against the front end of the locking part 2251; the flying fork telescopic component also includes a first return tension spring 227, a first tension spring fixing hole is provided at the flying fork limiting seat 223, a second tension spring fixing hole 2224 is provided at the front end of the flying fork telescopic shaft 222, and the two ends of the first return tension spring 227 are fixed to the first tension spring fixing hole and the second tension spring fixing hole 2224 respectively by fixing screws.When the fork arm 221 needs to move forward, the fork power component pushes the fork telescopic shaft 222. The fork power component first contacts the transmission part 2252 of the fork tensioning pin 225 and pushes the fork tensioning pin 225, causing it to move forward within the limiting cavity 2222. As the fork tensioning pin 225 moves forward, the gap between the locking part 2251 and the fork limiting pin 224 increases, unlocking the fork telescopic shaft 222 and the fork limiting seat 223. Simultaneously, as the fork tensioning pin... The forward movement of 225 compresses the first return spring 226, causing it to store force. After the fork tension pin 225 moves forward to one position, the transmission part 2252 enters the limiting cavity 2222 through the unlocking hole 2223. At this time, the fork power component contacts the fork telescopic shaft 222. Since the fork telescopic shaft 222 has been unlocked from the fork limiting seat 223, it can be pushed. When the fork telescopic shaft 222 moves forward, it stores force in the first return spring 227. The fork extension shaft 222 drives the fork arm 221 to move forward. When the fork arm 221 needs to move backward, the fork power component automatically resets. At this time, the first reset spring 227 located between the fork limit seat 223 and the fork extension shaft 222 will exert a pulling force on the fork extension shaft 222, causing the fork extension shaft 222 to move towards the fork limit seat 223 and eventually return to its original position. At the same time, the first reset spring 226 will also exert a pushing force on the fork tension pin 225, causing the fork tension pin 225 to move backward and move the transmission part... 2252 is pushed along the unlocking hole 2223 to the outside of the limiting cavity 2222. At the same time, the backward movement of the locking part 2251 will squeeze the fly fork limiting pin 224, causing the fly fork limiting pin 224 to be slightly pushed upward. It cooperates with the limiting waist-shaped hole 2231 provided at the fly fork limiting seat 223 to limit the fly fork telescopic shaft 222, thereby making the fly fork telescopic shaft 222 and the fly fork limiting seat 223 fixedly connected, so as to fix the fly fork arm 221, and thus make the fly fork arm 221 stably follow the winding assembly 210 to move synchronously.

[0038] The fork drive unit includes a fork push cylinder 228. The piston rod end of the fork push cylinder 228 is positioned towards the fork telescopic shaft 222. A fork push plate 2281 is provided at the piston rod end of the fork push cylinder 228. A fork push shaft 229 is provided on the side of the fork push plate 2281 facing the fork telescopic shaft 222. The fork push shaft 229 is used to push the fork telescopic shaft 222 and the fork tensioning pin 225. In this embodiment, the piston rod of the fork push cylinder 228 controls the fork push plate 2281, which in turn drives the fork push shaft 229 to push the fork telescopic shaft 222. Furthermore, the radius of the fork push shaft 229 is larger than the radius of the transmission part 2252 but smaller than the radius of the fork telescopic shaft 222.

[0039] The pre-pressure drive module includes a pre-pressure mounting plate, a vertical pre-pressure drive cylinder, a rotary motor, and a rotary mounting base. Both the vertical pre-pressure drive cylinder and the rotary motor are located at the frame 100. The pre-pressure mounting plate is positioned above the winding station. The piston rod end of the vertical pre-pressure drive cylinder is connected to the pre-pressure mounting plate and drives the pre-pressure mounting plate to move vertically. The rotary mounting base is rotatably mounted on the lower surface of the pre-pressure mounting plate. The rotary motor is connected to the rotary mounting base, and the pressure foot assembly is connected to the lower surface of the rotary mounting base. In this embodiment, the vertical pre-pressure cylinder drives the pre-pressure mounting plate to move vertically, thereby moving the pressure foot assembly vertically so that the pressure hole 321 can be fitted onto the hanging pin 910 of the workpiece 900, achieving pressure on the hanging pin 910. Simultaneously, the rotary motor drives the rotary mounting base to rotate 360°, facilitating adjustment of the pressure foot assembly and driving it to the next hanging pin 910 on the workpiece 900.

[0040] The presser foot assembly includes a first presser arm 311, a second presser arm 312, a presser foot sleeve 320, and a presser foot swing arm 322. The first presser arm 311 has a movable cavity 315. The lower end of the first presser arm 311 has a connecting hole communicating with the movable cavity 315. The upper end of the second presser arm 312 is movably disposed within the movable cavity 315 through the connecting hole. A second return spring 316 is disposed within the movable cavity 315. One end of the second return spring 316 abuts against the inner wall of the upper end of the movable cavity 315, and the other end of the second return spring 316 abuts against the inner wall of the second presser arm 312. The upper ends abut against each other, and the lower end of the second pressure arm 312 is connected to the upper end of the pressure foot sleeve 320. The pressure hole 321 is provided at the pressure foot sleeve 320 and extends to the lower end of the pressure foot sleeve 320. The pressure foot sleeve 320 is provided with a first pivot hole, and the lower end of the pressure foot swing arm 322 is provided with a second pivot hole corresponding to the first pivot hole. A connecting port is provided on one side of the pressure foot sleeve 320, which communicates with the pressure hole 321. The lower end of the pressure foot swing arm 322 enters the pressure hole 321 through the connecting port and forms a pressure head 323 that mates with the pressure hole 321. A pivot shaft 32 is provided outside the pressure foot sleeve 320. 6. The pivot shaft 326 passes through the first pivot hole and the second pivot hole in sequence to connect the presser foot sleeve 320 and the presser foot swing arm 322. A second return spring is connected between the outer side of the first presser arm 311 and the outer side of the presser foot swing arm 322. The second return spring ensures that the presser foot swing arm 322 is always close to the first presser arm 311. A push part 324 is provided in the middle of the presser foot swing arm 322. The height of the push part 324 is less than the height of the first presser arm 311. A push surface 325 is provided at the upper end of the push part 324. The lower end of the first presser arm 311 is provided with a push surface 325. The force-bearing surface 313 corresponding to the push surface 325 pushes the first pressure arm 311 to move downward, causing the force-bearing surface 313 to interact with the push surface 325 and causing the pressure foot swing arm 322 to move outward. At the same time, it causes the pressure head 323 to move in the pressure hole 321 and squeeze the space at the pressure hole 321 to press the external hanging needle 910. The push part 324 is set on one side facing the second pressure arm 312. The second pressure arm 312 is provided with a clearance hole 314 corresponding to the push part 324. The push surface 325 and the force-bearing surface 313 are both inclined at the same angle.In this embodiment, a pressure rod 310 is formed by combining a first pressure arm 311 and a second pressure arm 312 sleeved on the first pressure arm 311. During the downward pressing process of the pressure rod 310, the pressure hole 321 at the pressure foot sleeve 320 inserts the hanging needle 910 into the pressure hole 321. After the lower end of the pressure foot sleeve 320 abuts against the workpiece 900, as the pressure rod 310 continues to press down, the first pressure arm 311 moves toward the direction closer to the second pressure arm 312. At the same time, the force-bearing surface 313 at the lower end of the first pressure arm 311 is positioned at the pressure foot swing arm 322. The push surface 325 gradually approaches and eventually presses against the second pressure arm 312. As the first pressure arm 311 continues to approach the second pressure arm 312, the force-bearing surface 313 exerts a pushing force on the push surface 325, pushing the pressure foot swing arm 322 outward. At the same time, the pressure head 323 formed by the end of the pressure foot swing arm 322 located in the pressure hole 321 also compresses the space at the pressure hole 321 according to the lever principle, thereby pressing the opening of the hanging needle 910. By setting the clearance hole 314 at the second pressure arm 312, it is possible to facilitate the pressure foot swing arm 322 in its original position. After initial position or reset, the push part 324 is accommodated. By setting the push surface 325 and the force-receiving surface 313 as inclined surfaces at the same angle, the force-receiving surface 313 generates a strong pushing force on the push surface 325, thereby improving the outward pushing effect on the push part 324. By setting a second reset spring 316 in the movable cavity 315, the first pressure arm 311 is quickly reset after the first pressure arm 311 approaches the second pressure arm 312 and completes the pressing of the opening of the hanging needle 910, so as to facilitate the next pressing. In addition, To prevent the first pressure arm 311 from separating from the second pressure arm 312, a positioning pin is provided at the first pressure arm 311, and a positioning waist-shaped hole corresponding to the positioning pin is provided at the second pressure arm 312. The connection is achieved by the positioning pin cooperating with the positioning waist-shaped hole. The pressure foot sleeve 320 and the pressure foot swing arm 322 are pivotally connected by the pivot shaft 326 to facilitate the pressing of the opening of the external hanging needle 910. The pressure foot swing arm 322 is reset by the second reset spring to facilitate the next pressing, thereby improving the pressing efficiency.

[0041] In addition, to achieve more automated operation, the machine is equipped with multiple mechanisms such as a wire cutting mechanism 400, a position adjustment mechanism 500, a flipping mechanism 600, a guard plate mechanism 700, and a core locking mechanism 800. The automation rate of the winding machine is improved by the cooperation of multiple mechanisms, thereby improving the processing efficiency.

[0042] A mounting platform is provided at the winding mechanism 200. The wire cutting mechanism 400 includes a wire cutting blade 410 and a wire cutting drive 420. The moving end of the wire cutting drive 420 is set towards the winding station. The wire cutting blade 410 is connected to the moving end of the wire cutting drive 420. The wire cutting blade 410 is set at an angle. The wire cutting drive 420 drives the wire cutting blade 410 to move towards the winding station and cuts the wire with the wire cutting blade 410 so that the workpiece 900 can be taken out after the winding is completed.

[0043] The position adjustment mechanism 500 includes a vertical position adjustment component, a horizontal position adjustment component, and a front-back position adjustment component. The vertical position adjustment component is driven by the horizontal position adjustment component and drives the horizontal position adjustment component to move vertically. The horizontal position adjustment component is driven by the front-back position adjustment component and drives the front-back position adjustment component to move horizontally. The front-back position adjustment component is driven by the winding mechanism 200 and drives the winding mechanism 200 to move back and forth. The position adjustment mechanism 500 can adjust the position of the winding mechanism 200, thereby improving the compatibility of the winding machine and facilitating the winding processing of workpieces 900 of different specifications.

[0044] To facilitate the loading and unloading of workpiece 900, a flipping mechanism 600 is used. A material inlet 110 is provided at one end of the frame 100. The flipping mechanism 600 includes a flipping material plate 610 and a flipping motor. The motor shaft of the flipping motor is connected to the flipping material plate 610. Multiple material racks 611 are provided at the flipping material plate 610. The workpiece 900 to be processed is manually placed on the material rack 611. The flipping motor drives the flipping material plate 610 to rotate, so that the material rack 611 with the workpiece 900 is moved to the winding station. At the same time, the wound workpiece 900 is moved to the material inlet 110, which makes it easier for the operator to unload the wound workpiece 900.

[0045] The guard plate mechanism 700 includes a guard plate mounting frame 710, a guard plate connecting plate 720, a left guard plate 730, and a right guard plate 740. The upper end of the guard plate mounting frame 710 is connected to the pre-pressing mounting plate. The guard plate connecting plate 720 is located at the lower end of one side of the guard plate mounting frame 710. The left guard plate 730 and the right guard plate 740 are respectively provided with the left and right ends of the guard plate connecting plate 720. Both the left guard plate 730 and the right guard plate 740 are arc-shaped. The front ends of the left guard plate 730 and the right guard plate 740 are close to each other and form a winding opening 750. The winding opening 750 only allows one side of the workpiece 900 to be wound to be exposed. At the same time, the left guard plate 730... The upper and lower ends of the front end of the left guard plate 730 and the upper and lower ends of the front end of the right guard plate 740 are all provided with arc-shaped chamfers. The left guard plate 730 and the right guard plate 740 cooperate with each other to protect the workpiece 900 during winding, so that the winding assembly 210 can only wind each part of the workpiece 900 gradually through the winding port 750, thereby preventing miswinding and improving the yield of the workpiece 900. At the same time, by providing arc-shaped chamfers at the upper and lower ends of the front end of the left guard plate 730 and the upper and lower ends of the front end of the right guard plate 740, the wire is effectively prevented from being broken during the winding process, effectively protecting the wire and ensuring the complete winding of that part of the workpiece 900.

[0046] The core locking mechanism 800 includes a top claw 810 and a top claw drive 820. The top claw drive 820 is located on the other side of the guard plate mounting bracket 710. The top claw drive 820 drives the top claw 810 to approach or move away from the workpiece 900 located at the winding station. When the workpiece 900 is being wound, the top claw drive 820 drives the top claw 810 to approach the workpiece 900 and engage the workpiece 900, so that the workpiece 900 cannot rotate during winding, thereby improving winding accuracy. When the workpiece 900 has completed this part of winding and needs to proceed to the next part of winding, the top claw drive 820 drives the top claw 810 to separate from the workpiece 900, so that the workpiece 900 can rotate, so that the next part of the workpiece 900 can be wound. This process is repeated, greatly improving winding efficiency.
