Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically a novel auxiliary tube-threading machine for CNC winding machines. Background Technology

[0002] Small low-frequency transformers are indispensable components in electronic products, used in various industries such as mobile phone chargers, televisions, and DC regulated switching power supplies. The manufacturing of these transformers mainly involves the winding of the bobbin coil, which takes up a lot of time and accounts for the largest proportion of the cost. As technology advances, safety regulations have also been improved, and the safety regulations for the production of these small low-frequency transformers are becoming increasingly stringent. Isolation bushings must be installed at the beginning and end of the transformer.

[0003] Initially, transformers with bushings at both the starting and ending ends were not suitable for automatic winding machines. They had to be wound using a CNC single-axis winding machine and manual tubing. Manually inserting very small bushings took a lot of time, resulting in very low winding efficiency. Although automatic bushing machines have been developed to address this issue, they are expensive and not suitable for small-batch production. For the ever-changing transformer specifications, small-batch production still relies heavily on manual winding, and this production method accounts for a very large proportion.

[0004] All existing tube threading machines on the market have the same structure, and are developed separately for single-wire / double-wire / multi-wire applications. While single-wire machines can also thread double-wire machines, the results are unstable. Currently, most tube threading mechanisms on the market use tube threading devices invented by other companies. During threading, there is a gap between the wire nozzle and the sleeve, resulting in a success rate of only about 70-80%. Furthermore, the tube threading machine structure consists of two wheels placed horizontally to press the wire and the sleeve, meaning that the two sets of clamps are placed vertically. This means that when threading fails, the sleeve cannot fall off, and manual removal of the sleeve from between the two sets of clamps is required to continue threading. Therefore, we propose a new type of auxiliary tube threading machine using a CNC winding machine. Summary of the Invention

[0005] The purpose of this invention is to provide a new type of auxiliary tube threading machine for CNC winding machines that is efficient, has a high success rate in tube threading, and can complete single-wire and double-wire operations in one machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel auxiliary tube-threading machine for CNC winding machines, comprising a base plate, a base, and a tube threading conduit. A side plate A is fixedly installed on the right end face of the base plate, and a guide wheel A is disposed on the side surface of the side plate A near the upper position. A sleeve disc is provided near the bottom of the side surface of the base plate. A sleeve perforation is opened on the outer surface of the side plate A. A base is fixedly installed on the upper surface of the base plate. A wire guide is provided on the outer surface of the base plate, and a notch is provided near the middle of the wire guide. A wire feeding mechanism is provided at the notch of the wire guide. A tube guide is provided on the outer surface of the base plate below the wire guide, and a notch is provided near the right side of the tube guide. A tube feeding mechanism is provided at the notch of the tube guide. A moving mechanism, a tube guiding mechanism, and a tube cutting mechanism are provided on the left side of the base plate. A connecting plate is fixedly installed on the rear side of the base plate. A side plate B is fixedly installed on the left end face of the base plate. A wire cutting mechanism is provided on the outer surface of the side plate B. Two sets of baffles are fixedly installed on the left outer surface of the side plate B. A guide wheel B is provided on the left outer surface of the side plate B.

[0007] As can be seen from the above scheme, by setting up a wire feeding mechanism, the wire can be stably fed, and by changing the thrust of the first cylinder, stable feeding of both single and double wires can be achieved. By setting up a tube feeding mechanism, the bushing can be stably fed, and because the pressure is applied by the elastic force of the spring, the bushing will not deform due to excessive force. By setting up a moving mechanism, the cut bushing can be moved to the end of the wire guide and aligned, which facilitates the tube threading operation. By setting up a tube threading mechanism, the two sets of clamps can be slightly opened and fully opened. Slightly opening makes it easy to insert the bushing into the two sets of clamps, and fully opening allows the wire to be taken out after the tube threading is completed. By setting up a tube cutting mechanism, the bushing can be cut after it is inserted into the two sets of clamps. By setting up a wire cutting mechanism, the wire can be cut after the transformer winding is completed.

[0008] In this embodiment, the wire feeding mechanism includes a first motor fixedly installed on the rear side of the base, and the end of the output shaft of the first motor extends to the front side of the base. A wire feeding wheel is sleeved on the outer surface of the end of the output shaft of the first motor, and the wire feeding wheel is located at the notch of the wire guide. Two sets of first cylinders are fixedly installed on the front side of the base. The ends of the push rods of the two sets of first cylinders are fixedly installed with a base A. A wire pressing wheel is provided on the lower surface of the base A, and the wire feeding wheel and the wire pressing wheel are located on the same center line.

[0009] As can be seen from the above scheme, the thrust applied by the first cylinder makes the pressure wheel and the feed wheel in close contact, and the feed wheel is driven to rotate by the first motor, thereby completing the purpose of conveying the line. Furthermore, by changing the rotation direction of the feed wheel, the purpose of feeding and pulling the line back can be achieved.

[0010] In this embodiment, the tube feeding mechanism includes a second motor fixedly installed on the rear side of the base, and the end of the output shaft of the second motor extends to the front side of the base. A tube feeding wheel is sleeved on the end of the output shaft of the second motor, and a groove is formed on the outer surface of the tube feeding wheel. An installation block is fixedly installed on the front side of the base. Two sets of guide grooves are formed inside the installation block. Guide rods are inserted into the two sets of guide grooves. A base B is fixedly installed at the bottom of the two sets of guide rods. An installation groove is formed inside the installation block. A spring is fixedly connected to the inner wall of the installation groove, and the bottom of the spring is fixedly connected to the upper surface of the base B. A tube pressing wheel is provided on the lower surface of the base B, and the tube pressing wheel and the tube feeding wheel are located on the same center line.

[0011] As can be seen from the above scheme, the guiding effect of the two sets of guide rods 305 and guide grooves 304 enables the pressing roller 309 to always be kept on the same horizontal line as the feeding roller 302. Under the action of the spring force of the spring 308, the pressing roller 309 will be in close contact with the feeding roller 302, and the feeding roller 302 will be rotated by the second motor 301 to complete the purpose of conveying the sleeve.

[0012] In this embodiment, the moving mechanism includes a fixed block fixedly installed on the rear side of the base. A second cylinder is provided on the upper side of the fixed block, and the end of the push rod of the second cylinder is fixedly connected to the upper surface of the fixed block. A vertical slide seat is fixedly installed on the outer surface of the base, and the vertical slide seat is slidably connected to the second cylinder. A fixed plate is fixedly installed on the outer surface of the second cylinder, and a third cylinder is fixedly installed on the outer surface of the fixed plate. A connecting block is fixedly installed on the end of the push rod of the third cylinder, and an mounting plate is fixedly installed on the outer surface of the connecting block. A horizontal slide seat is fixedly installed on the upper surface of the mounting plate, and the horizontal slide seat is slidably connected to the lower surface of the third cylinder.

[0013] As can be seen from the above scheme, since the end of the push rod of the second cylinder 402 is fixedly connected to the fixed block 401, when the second cylinder 402 is started, the main body of the second cylinder 402 will move upward and drive the third cylinder 405 to move. When the third cylinder 405 is started, the push rod of the third cylinder 405 will drive the mounting plate 407 to move, thereby driving the pipe threading mechanism 500 and the pipe cutting mechanism 600 mounted on the upper surface of the mounting plate 407 to move. The setting of the vertical slide base 403 and the horizontal slide base 408 can make the operation of the moving mechanism 400 more stable.

[0014] In this embodiment, the tube-passing mechanism includes a parallel finger-clamping cylinder fixedly mounted on the upper surface of the mounting plate. The outer surfaces of the two sets of clamping fingers of the parallel finger-clamping cylinder are fixedly mounted with tube-clamping claws. The opposing surfaces of the two sets of tube-clamping claws are fixedly connected with clamping blocks by bolts. A fourth cylinder is fixedly mounted on the outer surface of the left tube-clamping claw, and the end of the push rod of the fourth cylinder penetrates through the inner wall of the left tube-clamping claw and extends to the space between the two sets of tube-clamping claws. A push block is fixedly mounted on the end of the push rod of the fourth cylinder. An adjusting bolt is threaded through the inside of the right tube-clamping claw, and the end of the adjusting bolt contacts the outer surface of the push block. A tension spring is provided on the lower surface of the two sets of tube-clamping claws, and both ends of the tension spring are fixedly connected to the lower surface of the two sets of tube-clamping claws by bolts.

[0015] As can be seen from the above scheme, when the parallel clamping finger cylinder 501 is started, the two clamping fingers of the parallel clamping finger cylinder 501 will open the two sets of tube clamping jaws 502 significantly, making it easy to remove the wire with the sleeve inserted. If the insertion fails, the sleeve will fall off directly without manual removal, and the insertion operation can continue. When the fourth cylinder 504 is started, the push rod of the fourth cylinder 504 will push the push block 505 to move. Through the connection between the push block 505 and the adjusting bolt 506, the right-side tube clamping jaw 502 will move, making the two sets of tube clamping jaws 502 slightly open, making it easier to insert the sleeve between the two sets of clamping blocks 503. The two sets of clamping blocks 503 are connected by bolts, which makes them easy to disassemble and replace. Different clamping blocks 503 can be replaced according to the size of the sleeve to be inserted. The opening distance between the two sets of tube clamping jaws 502 when the fourth cylinder is started can be adjusted by turning the adjusting bolt 506, which facilitates the insertion of the sleeve.

[0016] In this embodiment, the pipe cutting mechanism includes a fifth cylinder disposed on the upper surface of the right pipe clamping jaw, and the end of the push rod of the fifth cylinder is fixedly connected to the upper surface of the right pipe clamping jaw. A vertical plate is fixedly connected to the lower surface of the fifth cylinder, and the end of the vertical plate extends through the outer surface of the right pipe clamping jaw to the space between the two sets of pipe clamping jaws. A pipe cutting blade is fixedly installed on the outer surface of the vertical plate, and the pipe cutting blade is disposed on the outside of the two sets of pipe clamping jaws.

[0017] As can be seen from the above scheme, when the fifth cylinder 601 is started, the main body of the fifth cylinder 601 will move upward, and drive the vertical plate 602 to move upward, so that the pipe cutting blade 603 can cut the sleeve and complete the operation of cutting the sleeve.

[0018] In this embodiment, the tangent mechanism includes an L-shaped plate fixedly installed on the inner wall of the left side of the side plate B. A Y-shaped finger-clamping cylinder is fixedly installed on the upper surface of the L-shaped plate. The ends of the two sets of fingers of the Y-shaped finger-clamping cylinder are fixedly installed with tangent clamping claws.

[0019] As can be seen from the above scheme, when the Y-type finger-clamping cylinder 702 is started, the two fingers of the Y-type finger-clamping cylinder 702 will retract inward and drive the two sets of wire-cutting jaws 703 to cut the wire, thus completing the wire-cutting operation.

[0020] In this embodiment, a protective cover is fixedly installed on the outer surface of the Y-shaped finger-clamping cylinder, and the upper surface of the protective cover is located on the upper side of the two sets of tangential grippers.

[0021] As can be seen from the above solutions, setting up a protective cover can provide protection and prevent workers from being injured due to accidental contact during operation.

[0022] In this embodiment, both the threading conduit and the tube conduit are fixedly equipped with wire nozzles on their left ends, and the left ends of both sets of wire nozzles are located on the outside of the base, and the left ends of both sets of wire nozzles are located on the same center line.

[0023] As can be seen from the above scheme, when the lead nozzle at the end of the conduit 106 comes into contact with the end of the sleeve, the end of the lead nozzle can slightly enter the interior of the sleeve, thereby improving the success rate of tube insertion.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In this invention, during pipe threading, the fourth cylinder is activated, causing the two sets of pipe clamping jaws to open slightly. Then, the pipe feeding wheel drives the sleeve into the space between the two sets of clamping blocks. The fifth cylinder drives the pipe cutting blade to cut the sleeve. Then, the two sets of pipe clamping jaws are moved so that the front end face of the sleeve is in contact with the end face of the threading conduit, so that there is no gap between the wire nozzle at the end of the threading conduit and the sleeve. At this time, the fourth cylinder is closed, and the two sets of pipe clamping jaws are pulled inward by the tension of the tension spring, causing the two sets of clamping blocks to hold the sleeve tightly and prevent it from loosening. This facilitates smooth threading and can perform single-wire and double-wire threading operations with stable efficiency and high success rate.

[0026] 2. In the wire feeding process, the first motor serves as the conveying power. By adjusting the pressure of the first cylinder, regardless of the wire diameter or whether it is a single or double wire, the center line connecting the wire feeding wheel and the pressure wheel is always orthogonal to the center line of the wire feeding wheel, thus achieving stable feeding. When feeding the sleeve, the pressure of the pressure wheel is maintained by a spring. Regardless of the size of the sleeve, the center line connecting the two conveying wheels is always orthogonal to the center line of the sleeve, ensuring stable and reliable tube feeding. This lays the foundation for the smooth threading of the sleeve and improves the success rate of sleeve feeding.

[0027] 3. This device adopts a double-wheel vertical pressing and pressing method for pipe pressing. The pipe-threading structure is completely different from other companies' pipe-threading devices. The two sets of clamping blocks are placed in parallel left and right, so that in the event of pipe-threading failure, the two sets of clamping claws open and the sleeve can fall off automatically. The pipe-threading operation can continue without manual removal, thus improving work efficiency. Attached Figure Description

[0042] Please see Figure 1-10 One embodiment provided by the present invention:

[0043] A new type of auxiliary sleeve threading machine for CNC winding machines includes a base plate 100, a base 105, and a threading conduit 106.

A sleeve through hole 104 is opened on the outer surface of the side plate A101. The base 105 is fixedly mounted on the upper surface of the base plate 100. The threading conduit 106 is provided on the outer surface of the base 105, and a notch is provided near the middle of the threading conduit 106. A wire feeding mechanism 20 is provided at the notch of the threading conduit 106. 0. A conduit 107 is provided on the outer surface of the base 105 below the conduit 106, and a notch is provided near the right side of the conduit 107. A tube feeding mechanism 300 is provided at the notch of the conduit 107. A moving mechanism 400, a tube feeding mechanism 500 and a tube cutting mechanism 600 are provided on the left side of the base 105. A connecting plate 108 is fixedly installed on the rear side of the base 105. A side plate B109 is fixedly installed on the left end face of the base plate 100.

A guide wheel B111 is provided on the left outer surface of the side plate B109.

[0044] Specifically, the wire feeding mechanism 200 includes a first motor 201 fixedly installed on the rear side of the base 105, and the end of the output shaft of the first motor 201 extends to the front side of the base 105. A wire feeding wheel 202 is sleeved on the outer surface of the end of the output shaft of the first motor 201, and the wire feeding wheel 202 is located at the notch of the wire guide tube 106. Two sets of first cylinders 203 are fixedly installed on the front side of the base 105. The ends of the push rods of the two sets of first cylinders 203 are fixedly installed on the base A204. A pressure wheel 205 is provided on the lower surface of the base A204, and the wire feeding wheel 202 and the pressure wheel 205 are located on the same center line. The thrust applied by the first cylinder 203 makes the pressure wheel 205 and the wire feeding wheel 202 in close contact, and drives the wire feeding wheel 202 to rotate through the first motor 201, thereby completing the purpose of feeding the wire. By changing the rotation direction of the wire feeding wheel 202, the purpose of feeding and pulling back the wire can be achieved.

[0045] Specifically, the tube feeding mechanism 300 includes a second motor 301 fixedly installed on the rear side of the base 105, with the end of the output shaft of the second motor 301 extending to the front side of the base 105. A tube feeding wheel 302 is sleeved on the end of the output shaft of the second motor 301, and a groove is formed on the outer surface of the tube feeding wheel 302. A mounting block 303 is fixedly installed on the front side of the base 105. Two sets of guide grooves 304 are formed inside the mounting block 303, and guide rods 305 are inserted into the two sets of guide grooves 304. A base B306 is fixedly installed at the bottom of the two sets of guide rods 305. A mounting groove 307 is formed inside the mounting block 303, and a spring 308 is fixedly connected to the inner wall of the mounting groove 307. The bottom of the spring 308 is fixedly connected to the upper surface of the base B306. The lower surface is provided with a pressing roller 309, and the pressing roller 309 and the feeding roller 302 are located on the same center line. The guiding effect of the two sets of guide rods 305 and guide grooves 304 ensures that the pressing roller 309 can always be kept on the same horizontal line as the feeding roller 302. When the pressing roller 309 is subjected to the elastic force of the spring 308, it will be in close contact with the feeding roller 302, and the second motor 301 drives the feeding roller 302 to rotate to complete the purpose of conveying the sleeve.

[0046] Specifically, the moving mechanism 400 includes a fixed block 401 fixedly installed on the rear side of the base 105. A second cylinder 402 is provided on the upper side of the fixed block 401, and the end of the push rod of the second cylinder 402 is fixedly connected to the upper surface of the fixed block 401. A vertical slide 403 is fixedly installed on the outer surface of the base 105, and the vertical slide 403 is slidably connected to the second cylinder 402. A fixed plate 404 is fixedly installed on the outer surface of the second cylinder 402. A third cylinder 405 is fixedly installed on the outer surface of the fixed plate 404. A connecting block 406 is fixedly installed on the end of the push rod of the third cylinder 405. An mounting plate 407 is fixedly installed on the outer surface of the connecting block 406. A horizontal slide 408 is fixedly installed on the upper surface of the mounting plate 407, and the horizontal slide 408 is slidably connected to the lower surface of the third cylinder 405. Because the end of the push rod of the second cylinder 402 is fixedly connected to the fixed block 401... The fixed connection means that when the second cylinder 402 is started, the main body of the second cylinder 402 will move upward and drive the third cylinder 405 to move. When the third cylinder 405 is started, the push rod of the third cylinder 405 will drive the mounting plate 407 to move, which in turn drives the pipe-passing mechanism 500 and the pipe-cutting mechanism 600 mounted on the upper surface of the mounting plate 407 to move. The setting of the vertical slide base 403 and the horizontal slide base 408 can make the operation of the moving mechanism 400 more stable.

[0047] Specifically, the pipe-penetrating mechanism 500 includes a parallel gripping finger cylinder 501 fixedly mounted on the upper surface of the mounting plate 407. Both sets of gripping fingers of the parallel gripping finger cylinder 501 are fixedly mounted with pipe-gripping jaws 502. The opposing surfaces of the two sets of pipe-gripping jaws 502 are fixedly connected with clamping blocks 503 by bolts. A fourth cylinder 504 is fixedly mounted on the outer surface of the left pipe-gripping jaw 502, and the end of the push rod of the fourth cylinder 504 penetrates through the inner wall of the left pipe-gripping jaw 502 and extends between the two sets of pipe-gripping jaws 502. A push block 505 is fixedly mounted on the end of the push rod of the fourth cylinder 504. The right pipe-gripping jaw 502 is penetrated internally and... The threaded connection includes an adjusting bolt 506, the end of which contacts the outer surface of the push block 505. A tension spring 507 is provided on the lower surface of the two sets of clamping jaws 502, and both ends of the tension spring 507 are fixedly connected to the lower surface of the two sets of clamping jaws 502 by bolts. When the parallel clamping finger cylinder 501 is activated, its two fingers will significantly open the two sets of clamping jaws 502, facilitating the removal of the threaded wire. If threading fails, the sleeve will fall off directly, eliminating the need for manual removal and allowing the threading operation to continue. When the fourth cylinder 504 is activated... The push rod will push the push block 505 to move, and through the connection between the push block 505 and the adjusting bolt 506, it will drive the right-side clamping jaw 502 to move, so that the two sets of clamping jaws 502 are slightly opened, making it easier to insert the sleeve between the two sets of clamping blocks 503. The two sets of clamping blocks 503 are connected by bolts, which makes it easy to disassemble and replace them. Different clamping blocks 503 can be replaced according to the size of the sleeve to be inserted. The opening distance between the two sets of clamping jaws 502 can be adjusted by turning the adjusting bolt 506 when the fourth cylinder is started, which makes it easier to insert the sleeve.

[0048] Specifically, the pipe cutting mechanism 600 includes a fifth cylinder 601 disposed on the upper surface of the right-side pipe clamping jaw 502, and the end of the push rod of the fifth cylinder 601 is fixedly connected to the upper surface of the right-side pipe clamping jaw 502. A vertical plate 602 is fixedly connected to the lower surface of the fifth cylinder 601, and the end of the vertical plate 602 extends through the outer surface of the right-side pipe clamping jaw 502 to the space between the two sets of pipe clamping jaws 502. A pipe cutting blade 603 is fixedly installed on the outer surface of the vertical plate 602, and the pipe cutting blade 603 is disposed on the outside of the two sets of pipe clamping jaws 502. When the fifth cylinder 601 is activated, the main body of the fifth cylinder 601 moves upward and drives the vertical plate 602 to move upward, so that the pipe cutting blade 603 can cut the sleeve and complete the operation of cutting the sleeve.

[0049] Specifically, the wire cutting mechanism 700 includes an L-shaped plate 701 fixedly installed on the inner left side wall of the side plate B109. A Y-shaped finger-clamping cylinder 702 is fixedly installed on the upper surface of the L-shaped plate 701. The ends of the two sets of fingers of the Y-shaped finger-clamping cylinder 702 are fixedly installed with wire cutting claws 703. When the Y-shaped finger-clamping cylinder 702 is activated, the two fingers of the Y-shaped finger-clamping cylinder 702 will retract inward and drive the two sets of wire cutting claws 703 to cut the wire, thus completing the wire cutting operation.

[0050] Specifically, a protective cover 704 is fixedly installed on the outer surface of the Y-type gripper cylinder 702, and the upper surface of the protective cover 704 is set on the upper side of the two sets of tangential grippers 703. By setting the protective cover 704, a protective function can be achieved to prevent workers from being injured due to accidental contact during operation.

[0051] Specifically, both the left end of the threading conduit 106 and the tube threading conduit 107 are fixedly equipped with wire nozzles, and the left ends of both sets of wire nozzles are located outside the base 105. Furthermore, the left ends of the two sets of wire nozzles are located on the same center line. When the wire nozzle at the end of the threading conduit 106 contacts the end of the sleeve, the end of the wire nozzle can slightly enter the interior of the sleeve, thereby improving the success rate of tube threading.

[0052] Working principle: When using this device, the wire is passed through the guide wheel A102 and into the wire guide tube 106, passing between the wire feeding wheel 202 and the wire pressing wheel 205. The sleeve is then passed through the sleeve through hole 104 into the tube guide tube 107, and then between the tube feeding wheel 302 and the tube pressing wheel 309. Subsequently, the second motor 301 is started to transport the sleeve forward. At the same time, the fourth cylinder 504 is started. The push rod of the fourth cylinder 504 pushes the push block 505 to move, which in turn moves the right-side tube clamping jaws 502, causing the two sets of tube clamping jaws 502 to open slightly and allow the sleeve to pass through. Positioned between the two sets of clamping blocks 503, the fourth cylinder 504 is then closed. The two sets of clamping jaws 502, under the tension of the tension spring 507, cause the two sets of clamping blocks 503 to retract inward, clamping the sleeve. The fifth cylinder 601 is then activated, driving the cutting blade 603 to cut the sleeve. The fourth cylinder 504 is then activated again, opening the two sets of clamping blocks 503, and the feeding wheel 302 is activated, again driving the sleeve between the two sets of clamping blocks 503 and pushing the previously cut sleeve forward. The fourth cylinder 504 is then closed again, clamping the sleeve, and the fifth cylinder 601 again drives the cutting blade 603. The sleeve is cut off, leaving two sleeves of equal length between the two sets of clamping blocks 503. Then, the third cylinder 405 first moves the clamping jaws 502 to the left, followed by the second cylinder 402 moving them upwards, positioning the sleeve between the two sets of clamping blocks 503 at the front end of the threading conduit 106. Then, cylinder 504 is activated again to slightly open the two sets of clamping blocks 503. Next, the third cylinder 405 moves the clamping jaws 502 to the right, inserting the threading conduit 106 into the two sets of clamping blocks 503 and pushing the sleeve inwards. At this point, the front end of the sleeve is in contact with the wire tip on the end face of the threading conduit 106. Then, the fourth cylinder 504 closes, and the two sets of clamping jaws 502 contract inwards under the tension of the tension spring 507, clamping the sleeve between the two sets of clamping blocks 503. At this point, the first motor 201 is activated, driving the wire feeding wheel 202. The machine rotates to feed the wire forward and through the sleeve, completing the wire threading action. Then, the parallel finger-clamping cylinder 501 is activated, driving the two sets of sleeve-clamping claws 502 to open, allowing the operator to hold the threaded end. Subsequently, the first motor 201 is activated to continue feeding the wire forward. The operator holds one end of the wire and passes it between the two sets of cutting claws 703, wrapping the sleeve on the front side around the transformer pin, and passing the wire at the rear end between the two sets of baffles 110. Since the distance between the two sets of baffles 110 is too great for the sleeve to pass through, the rear sleeve is stuck behind the two sets of baffles 110. After the CNC winding machine completes the winding of the transformer, the Y-type finger-clamping cylinder 702 is activated to drive the two sets of cutting claws 703 to cut the wire. The operator then wraps the remaining wire and sleeve around the transformer pin. Subsequently, the first motor 201 drives the wire feeding wheel 202 to reverse, pulling the wire into the threading guide tube 106 for the next sleeve operation.
