Description

Technical Field

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

[0002] Winding machines are commonly used in the manufacture of electronic components such as transformers and inductors, winding enameled wire onto a bobbin or magnetic core. One type of winding machine, used for winding transformer bobbins, mainly includes a wire feeding device and a winding shaft that drives the bobbin to rotate, thus winding the enameled wire onto the bobbin. Another type, used for winding toroidal magnetic cores, mainly includes a wire hook and a wire-pulling mechanism, employing a cyclic wire hooking method. Neither of these winding methods is suitable for directly winding wire onto two parallel wire-receiving posts on a square magnetic core. The latter might be achievable with modifications, but the hooking method requires the wire hook and wire-pulling mechanism to continuously cycle, inevitably leading to lower winding efficiency. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a winding machine capable of rapidly winding wire onto two parallel wire-receiving posts on a magnetic core.

[0004] According to an embodiment of the present invention, a winding machine is used to wind two enameled wires onto two parallel receiving posts on a magnetic core, wherein the beginning and end of the enameled wires extend to the outside of the magnetic core. The winding machine includes a clamp, a front die, a rear die, and a wire pushing device. The clamp is configured to mount the magnetic core on which the receiving posts extend vertically. The front die and the rear die are respectively disposed on the front and rear sides of the clamp, and both the front die and the rear die are movable in the front-rear direction to approach or move away from the clamp. The front die and the rear die together form two left-right distributed limiting through holes, which are respectively used for the two receiving posts to pass through. The inner wall of each of the limiting through holes is provided with a spiral groove, and the axial direction of the two spiral grooves is extended in the vertical direction. The rear mold is provided with two wire holes that are extended in the front-back direction. The two wire holes are respectively connected to one end of the two spiral grooves. The two wire holes are respectively used for two enameled wires to pass through. The wire pushing device is configured to push the enameled wire through the wire hole and into the spiral groove. The two wire ends of the two enameled wires move along the inner wall of the two spiral grooves and extend to the other end of the two spiral grooves, so that the two enameled wires are respectively wound around the two receiving posts.

[0005] It has at least the following beneficial effects: First, the magnetic core is positioned using a clamp, then the mold is closed. Two wire receiving posts are respectively inserted into the two limiting through holes formed by the front and rear molds. The inner walls of the two limiting through holes are provided with spiral grooves. Then, a wire pushing device simultaneously drives two enameled wires to move towards the clamp. The two wire ends pass through the two wire holes and abut against the inner walls of the two spiral grooves. The inner walls of the spiral grooves force the wire ends to deform. The wire pushing device continues to drive the two enameled wires to move towards the clamp. The two wire ends move along the inner walls of the two spiral grooves and extend to the other end of the two spiral grooves, so that the middle parts of the two enameled wires are respectively wound around the two wire receiving posts. After the mold is opened, the wound magnetic core can be removed from the clamp. This method is convenient, quick, and has high winding efficiency.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0018] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0019] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 3 This invention discloses a winding machine, which is used to wind two enameled wires 1 onto two parallel receiving posts 21 on a magnetic core 2. The head 11 and tail 12 of each enameled wire 1 extend to the outside of the magnetic core 2. The receiving post 21 is the area on the magnetic core 2 where the enameled wire 1 is wound. The enameled wire 1 is a common round wire.

[0021] Reference Figure 1 The winding machine includes a clamp 3, a front mold 4, a rear mold 5, and a wire pushing device 7.

[0022] Reference Figure 3 The clamp 3 is configured to mount the magnetic core 2, which extends vertically along the wire receiving post 21. The upper surface of the clamp 3 is provided with a limiting groove 31, which is adapted to the lower end of the magnetic core 2. The lower end of the magnetic core 2 is mounted in the limiting groove 31, which limits the lower end of the magnetic core 2 in the horizontal direction, preventing the magnetic core 2 from shifting in the horizontal direction, so that the magnetic core 2 is in a vertical position, and thus the axial direction of the two wire receiving posts 21 of the magnetic core 2 extends vertically.

[0023] Reference Figure 1 and Figure 2 The front mold 4 and the rear mold 5 are respectively located on the front and rear sides of the fixture 3. Both the front mold 4 and the rear mold 5 can move in the front-back direction, allowing them to approach or move away from the fixture 3. When the front mold 4 and the rear mold 5 abut against each other, they both approach the fixture 3, completing the mold closing. The front mold 4 and the rear mold 5 together form two left-right distributed limiting through holes, which are used for the two wire receiving posts 21 to pass through. The front mold 4 and the rear mold 5 are in a state of surrounding the two wire receiving posts 21. The inner walls of the two limiting through holes are provided with spiral grooves 6, and the axial direction of the two spiral grooves 6 is extended in the vertical direction. Figure 4 and Figure 5 The rear mold 5 is provided with two wire holes 51 that extend axially in the front-back direction. The two wire holes 51 are respectively connected to one end of the two spiral grooves 6, and the two wire holes 51 are respectively used for two enameled wires 1 to pass through.

[0024] The wire pushing device 7 is configured to push the enameled wire 1 through the wire hole 51 and into the spiral groove 6. The two ends 11 of the two enameled wires 1 move along the inner walls of the two spiral grooves 6 and extend to the other end of the two spiral grooves 6, so that the two enameled wires 1 are respectively wound around the two receiving posts 21.

[0025] Initially, the front mold 4 and the rear mold 5 are in the open state, and the clamp 3 is located between the front mold 4 and the rear mold 5. The front mold 4 and the rear mold 5 are both far away from the clamp 3, which facilitates the installation of the lower end of the magnetic core 2 onto the clamp 3. Then, the molds are closed, driving the front mold 4 and the rear mold 5 to move closer to each other. The front mold 4 and the rear mold 5 are close to the clamp 3 and abut against each other. The front mold 4 and the rear mold 5 form two limiting through holes in the corresponding area of ​​the clamp 3. At this time, the two wire receiving posts 21 are respectively located in the two limiting through holes, and the two wire holes 51 are respectively connected to one end of the two spiral grooves 6. Then, the wire pushing device 7 moves towards the clamp 3. The wire pushing device 7 abuts against the two wire ends 12 of the two enameled wires 1. The wire pushing device 7 pushes the two wire ends 11 of the two enameled wires 1 into the two wire holes 51 respectively. Under the guidance of 1, the two wire ends 11 will respectively abut against the inner wall of one end of the two spiral grooves 6. Under the continuous pushing of the wire pushing device 7 and the guidance of the inner wall of the spiral groove 6, the wire ends 11 of the enameled wire 1 move along the inner wall of the spiral groove 6 toward the other end of the spiral groove 6 until the two wire ends 11 of the two enameled wires 1 extend to the other end of the two spiral grooves 6 respectively. During this process, the two enameled wires 1 are deformed into a spiral shape and the two enameled wires 1 are wound on the two wire receiving posts 21 to complete the winding of the magnetic core 2 and obtain the required electronic components or products. Finally, the front mold 4 and the rear mold 5 move away from each other again, that is, the front mold 4 and the rear mold 5 move away from the fixture 3. The mold is opened again, and the electronic components can be removed from the fixture 3, and the lower end of the other magnetic core 2 can be installed on the fixture 3.

[0026] First, the magnetic core 2 is positioned using clamp 3, then the mold is closed. Two wire receiving posts 21 are respectively inserted into the two limiting through holes formed by the front mold 4 and the rear mold 5. The inner walls of the two limiting through holes are provided with spiral grooves 6. Then, the wire pushing device 7 simultaneously drives the two enameled wires 1 to move towards the clamp 3. The two wire ends 11 pass through the two wire holes 51 and abut against the inner walls of the two spiral grooves 6. The inner walls of the spiral grooves 6 force the wire ends 11 to deform. The wire pushing device 7 continues to drive the two enameled wires 1 to move towards the clamp 3. The two wire ends 11 move along the inner walls of the two spiral grooves 6 and extend to the other end of the two spiral grooves 6, so that the middle parts of the two enameled wires 1 are respectively wound on the two wire receiving posts 21. After the mold is opened, the wound magnetic core 2 can be removed from the clamp 3. This is convenient, quick, and has high winding efficiency. The winding method of the winding machine is different from the working methods of the two existing types of winding machines.

[0027] It should be understood that, in order to facilitate the connection of the enameled wire 1 with other components, refer to... Figure 3Both the wire head 11 and the wire tail 12 extend beyond the receiving post 21 and have a certain length. The wire head 11, which extends beyond the other end of the spiral groove 6, will not interfere with the clamp 3, the front mold 4, or the rear mold 5. When the mold is opened again, since the enameled wire 1 is already wound on the receiving post 21 and the magnetic core 2 is limited on the clamp 3, the rear mold 5 moves backward to move away from the clamp 3. The clamp 3, the magnetic core 2, and the enameled wire 1 will not move with the rear mold 5, so the wire tail 12 will completely pass through the wire hole 51 and detach from the rear mold 5.

[0028] The axial direction of the wire hole 51 extends in the front-back direction. The axial direction of the wire hole 51 is perpendicular to the axial direction of the spiral groove 6. When the wire pushing device 7 pushes the end 11 of the enameled wire 1 into the spiral groove 6 and extends it to the other end of the spiral groove 6, the wire pushing device 7 stops driving the enameled wire 1. The end 12 of the enameled wire 1 is in the wire hole 51. The wire hole 51 shapes the end 12. After the rear mold 5 moves backward and away from the fixture 3, the end 12 exits the wire hole 51, so that the end 12 continues to extend in the front-back direction and the axial direction of the end 12 is perpendicular to the axial direction of the wire receiving post 21.

[0029] Reference Figure 5 The inner wall of the wire hole 51 and the inner wall of one end of the spiral groove 6 intersect at a point. The tangent direction of the inner wall of the spiral groove 6 at the intersection point is parallel to the axis of the wire hole 51, so that when the wire end 11 of the enameled wire 1 passes through the wire hole 51, it just touches the inner wall of one end of the spiral groove 6. The wire end 11 can be deformed or deformed from the moment it enters the spiral groove 6, so that the wire end 11 and the middle part of the enameled wire 1 move along the spiral trajectory of the spiral groove 6, and finally the middle part of the enameled wire 1 is wound around the receiving post 21.

[0030] In this embodiment, one end of the spiral groove 6 refers to the lower end of the spiral groove 6, and the other end of the spiral groove 6 refers to the upper end of the spiral groove 6. The two wire holes 51 are arranged symmetrically from left to right, and the two limiting through holes are also arranged symmetrically from left to right.

[0031] Reference Figures 4 to 6 It is understood that the rear side of the front mold 4 has two first semi-spiral grooves distributed left and right, and the front side of the rear mold 5 has two second semi-spiral grooves distributed left and right. The cross-sections of the first and second semi-spiral grooves are both semi-circular. One first semi-spiral groove and one second semi-spiral groove combine to form a complete spiral groove 6, which spirals upward from bottom to top. A spiral channel is formed between the front mold 4, the rear mold 5, and the wire receiving post 21 located in the limiting through hole. The spiral channel spirals upward from bottom to top and allows the enameled wire 1 to pass through. The width of the spiral channel is adapted to the diameter of the enameled wire 1.

[0032] Reference Figure 1 In some embodiments, the winding machine further includes a conductor block 8, see reference to Figure 7 and Figure 8The conductor block 8 is provided with two conductor grooves 81, which are connected to two conductor holes 51 respectively. The two conductor grooves 81 are coaxially arranged with the two conductor holes 51 respectively. Both the conductor grooves 81 and the conductor holes 51 extend in the front-back direction. The conductor grooves 81 are configured to limit and guide the enameled wire 1, and guide the enameled wire 1 to the conductor holes 51 through the conductor grooves 81.

[0033] Reference Figure 1 , Figure 7 , Figure 8 and Figure 9 The wire pushing device 7 includes a pushing block 71, on which two wire pushing parts 711 are provided. The two wire pushing parts 711 can be respectively inserted into two wire grooves 81. Initially, the two wire pushing parts 711 are respectively outside the two wire grooves 81. The two ends 11 of the two enameled wires 1 are placed in the two wire grooves 81. Then, the two wire pushing parts 711 are respectively aligned with the two wire grooves 81. The two wire pushing parts 711 move towards the clamp 3 and abut against the two ends 12 of the two enameled wires 1. By pushing the ends 12 through the wire pushing parts 711, the enameled wires 1 are pushed into the wire grooves 81 and move towards the wire hole 51 in the wire grooves 81. The ends 11 of the enameled wires 1 pass through the wire hole 51 and abut against the inner wall of the spiral groove 6. Since the wire grooves 81 are configured to limit and guide the enameled wires 1, the enameled wires 1 in the wire grooves 81 can only move towards the wire hole 51 without bending, ensuring that the enameled wires 1 can smoothly enter the wire hole 51. Alternatively, initially, the two pusher parts 711 are positioned outside the two wire grooves 81, and the two enameled wires 1 are completely placed inside the two wire grooves 81. Then, the two pusher parts 711 are aligned with the two wire grooves 81, and the two pusher parts 711 move towards the clamp 3 and abut against the two ends 12 of the two enameled wires 1. By pushing the ends 12 through the pusher parts 711, the enameled wires 1 are driven to move towards the wire hole 51 inside the wire groove 81. The wire ends 11 of the enameled wires 1 pass through the wire hole 51 and abut against the inner wall of the spiral groove 6.

[0034] Reference Figure 8 In some embodiments, the wire groove 81 includes a clearance area 811 and a limiting area 812 distributed vertically. The width of the clearance area 811 is smaller than the width of the limiting area 812. The width of the limiting area 812 is adapted to the diameter of the enameled wire 1. The push block 71 is connected to the push part 711 through the connecting part 712. The connecting part 712 and the push part 711 can pass through the clearance area 811 and the limiting area 812 respectively, so that when the enameled wire 1 is pushed by the push part 711 in the limiting area 812, the enameled wire 1 is limited by the inner wall of the limiting area 812 and cannot be bent. The enameled wire 1 can only move along the length direction of the wire groove 81, so that the enameled wire 1 enters the wire hole 51 in a straight state.

[0035] The connecting part 712 strengthens the structural strength of the pusher part 711, ensuring that the pusher part 711 has greater structural strength, thereby ensuring that the pusher part 711 can push the enameled wire 1 to move within the conductor groove 81. The length direction of the pusher block 71, the connecting part 712, and the pusher part 711 is all in the front-to-back direction. The pusher block 71, the connecting part 712, and the pusher part 711 are distributed from top to bottom, and the pusher block 71, the connecting part 712, and the pusher part 711 are an integral structure.

[0036] In another embodiment, the wire pushing device 7 includes a push rod that can extend from back to front into the wire groove 81. The push rod can abut against the end of the wire 12. The push rod drives the enameled wire 1 to move in the wire groove 81 toward the wire hole 51. The end of the enameled wire 1 1 passes through the wire hole 51 and abuts against the inner wall of the spiral groove 6.

[0037] Reference Figure 1 , Figure 10 and Figure 11 In some embodiments, the winding machine also includes a wire receiving block 9. The upper surface of the wire receiving block 9 is provided with two wire receiving grooves 91. The two wire receiving grooves 91 are respectively connected to two wire guide grooves 81. The two wire receiving grooves 91 are coaxially arranged with the two wire guide grooves 81. The longitudinal section of the two wire receiving grooves 91 is U-shaped. The wire receiving grooves 91 are configured to install enameled wire 1 from top to bottom. The enameled wire 1 can fall into the wire receiving groove 91 conveniently and quickly from top to bottom. At this time, the enameled wire 1 is facing the wire guide groove 81.

[0038] Two pusher sections 711 can be respectively inserted into two receiving grooves 91. After the enameled wire 1 is placed in the receiving groove 91, the pusher section 711 moves towards the clamp 3. The pusher section 711 can abut against the end 12 of the enameled wire 1 in the receiving groove 91 and move the enameled wire 1 towards the conductor groove 81. The enameled wire 1 enters the conductor groove 81 from the receiving groove 91. The pusher section 711 continues to move towards the clamp 3, so that the enameled wire 1 moves towards the clamp 3 in the conductor groove 81. The end 11 of the enameled wire 1 passes through the conductor hole 51 and abuts against the inner wall of one end of the spiral groove 6. The enameled wire 1 deforms and moves along the inner wall of one end of the spiral groove 6 towards the other end of the spiral groove 6 until the end 11 of the enameled wire 1 extends to the other end of the spiral groove 6, completing the winding of the magnetic core 2.

[0039] It is conceivable that the rear mold 5, the wire guide block 8, and the wire receiving block 9 are arranged side by side from front to back, so that a wire guide hole 51, a wire guide groove 81, and a wire receiving groove 91 are coaxial and connected in sequence. Initially, the wire pusher 711 is located at the rear end of the wire receiving groove 91 or behind the wire receiving block 9. The wire pusher 711 is coaxial with the wire receiving groove 91, and the movement trajectory of the wire pusher 711 is in the front-back direction.

[0040] Reference Figure 10In some embodiments, a third clearance groove 92 is provided in the middle of the upper surface of the wire receiving block 9. The third clearance groove 92 is perpendicular to and connected to the two wire receiving grooves 91. The depth of the third clearance groove 92 is greater than or equal to the depth of the wire receiving groove 91. The third clearance groove 92 allows the grippers or fingers of the feeding enameled wire 1 to be inserted so that the grippers or fingers can accurately insert the enameled wire 1 from top to bottom into the wire receiving groove 91.

[0041] Reference Figure 1 In some embodiments, the winding machine further includes a base 10, a guide rail 103 on the base 10, a clamp 3 above the guide rail 103, and a front mold 4 and a rear mold 5 slidably disposed at the front and rear ends of the guide rail 103, respectively. Both the front mold 4 and the rear mold 5 can slide on the guide rail 103. The arrangement of the guide rail 103 can reduce the resistance encountered by the front mold 4 and the rear mold 5 when they move in the front-rear direction.

[0042] In some embodiments, the winding machine further includes a first linear drive mechanism 101 and a second linear drive mechanism 102, both disposed on the base 10. The output end of the first linear drive mechanism 101 is connected to the front mold 4 and is used to drive the front mold 4 to move closer to or away from the clamp 3. The output end of the second linear drive mechanism 102 is connected to the rear mold 5 and is used to drive the rear mold 5 to move closer to or away from the clamp 3.

[0043] In this embodiment, the guide rail 103 extends along the front-to-back direction in its length direction. The moving directions of the output ends of the first linear drive mechanism 101 and the second linear drive mechanism 102 both extend along the front-to-back direction. The output end of the first linear drive mechanism 101 is connected to a first sliding plate, and the output end of the first linear drive mechanism 101 is connected to the front mold 4 through the first sliding plate. The first sliding plate is mounted on the guide rail 103 through a first guide block. The output end of the second linear drive mechanism 102 is connected to the rear mold 5 through a second sliding plate, and the second sliding plate is mounted on the guide rail 103 through a second guide block.

[0044] Reference Figure 1In some embodiments, the wire pushing device 7 further includes a third linear drive mechanism 72. The output end of the second linear drive mechanism 102 is connected to the third linear drive mechanism 72, and the output end of the third linear drive mechanism 72 is connected to the push block 71. When the second linear drive mechanism 102 drives the rear mold 5 to approach or move away from the clamp 3, the third linear drive mechanism 72, the push block 71, and the rear mold 5 simultaneously approach or move away from the clamp 3. The third linear drive mechanism 72 is used to drive the push block 71 to approach or move away from the clamp 3. When the drive block 71 approaches the clamp 3, the two push parts 711 can abut against the two ends 12 of the two enameled wires 1. The two push parts 711 push the two ends 11 of the two enameled wires 1 into the two wire holes 51 and abut against the inner wall of one end of the two spiral grooves 6, so that the enameled wires 1 are deformed and move along the inner wall of one end of the spiral grooves 6 toward the other end of the spiral grooves 6 until the two ends 11 of the two enameled wires 1 extend to the other end of the two spiral grooves 6, so that the enameled wires 1 are spirally wound on the receiving post 21, and the winding of the magnetic core 2 is completed.

[0045] The rear mold 5, the wire guide block 8, and the wire receiving block 9 are arranged sequentially from front to back. The rear mold 5, the wire guide block 8, the wire receiving block 9, and the third linear drive mechanism 72 are all connected to the output end of the second linear drive mechanism 102. The second linear drive mechanism 102 synchronously drives the rear mold 5, the wire guide block 8, the wire receiving block 9, and the third linear drive mechanism 72 to move. The rear mold 5, the wire guide block 8, the wire receiving block 9, and the third linear drive mechanism 72 always maintain a constant relative position.

[0046] When the enameled wire 1 moves along the inner wall of one end of the spiral groove 6 toward the other end of the spiral groove 6, the enameled wire 1 will apply a forward force to the front mold 4 and a backward force to the rear mold 5, causing the front mold 4 and the rear mold 5 to move away from each other.

[0047] The front mold 4 and the rear mold 5 are slidably disposed at the front and rear ends of the guide rail 103, respectively. The front mold 4 and the rear mold 5 are disposed on the front and rear sides of the fixture 3. The driving force of the first linear drive mechanism 101 is greater than that of the second linear drive mechanism 102. When the front mold 4 and the rear mold 5 are close to the fixture 3, the front mold 4 and the rear mold 5 abut against each other. Because the driving force of the first linear drive mechanism 101 is greater than that of the second linear drive mechanism 102, the front mold 4 and the rear mold 5 can be prevented from moving away from each other due to the force of the enameled wire 1, ensuring that the front mold 4 and the rear mold 5 can fit tightly together, thereby ensuring the integrity of the spiral groove 6.

[0048] In another embodiment, refer to Figure 4 and Figure 6The lower end of the rear side of the front mold 4 is provided with a first clearance groove, and the lower end of the front side of the rear mold 5 is provided with a second clearance groove. The fixture 3 is provided with a boss, and the upper surface of the boss is provided with a limiting groove 31. The upper end of the rear side of the front mold 4 is provided with two first half limiting through holes, and the inner wall of each of the two first half limiting through holes is provided with a first half spiral groove. The two first half limiting through holes are distributed left and right and are both located above the first clearance groove. The upper end of the front side of the rear mold 5 is provided with two second half limiting through holes, and the inner wall of each of the two second half limiting through holes is provided with a second half spiral groove. The two second half spiral grooves are distributed left and right and are both located above the second clearance groove. One first half limiting through hole and one second half limiting through hole form a complete limiting through hole. One first half spiral groove and one second half spiral groove form a complete spiral groove 6. The spiral groove 6 spirals upward from bottom to top. When the front mold 4 and the rear mold 5 approach and abut each other, the boss extends into the first clearance groove and the second clearance groove. At this time, the two wire receiving posts 21 of the magnetic core 2 on the boss are exactly in the two limiting through holes, and the relative position of the magnetic core 2 and the two limiting through holes is fixed, ensuring that the enameled wire 1 can move along one end of the spiral groove 6 to the other end of the spiral groove 6, and the enameled wire 1 is smoothly wound on the wire receiving post 21.

[0049] Reference Figure 6 In some embodiments, the rear mold 5 has an outlet 53 in the area above the two spiral grooves 6, see reference. Figure 4 and Figure 5 The rear mold 5 has straightening grooves 52 on both sides of the two spiral grooves 6. The two straightening grooves 52 extend in the left and right direction. The two guide parts 53 are used to guide the two left and right distributed wire ends 11 to extend to the left and right respectively.

[0050] Reference Figure 1 and Figure 2 The winding machine also includes a fourth linear drive mechanism 104 and a straightening block 105. The fourth linear drive mechanism 104 drives the straightening block 105 to move closer to or further away from the straightening groove 52. The straightening block 105 presses the wire end 11 against the inner wall of the straightening groove 52 to straighten the wire end 11. When the wire end 11 extends out of the spiral groove 6 and abuts against the guide part 53, the guide part 53 guides the wire end 11 to the straightening groove 52. Then the wire end 11 continues to extend into the straightening groove 52. During this process, the fourth linear drive mechanism 104 drives the straightening block 105 to reciprocate at a certain frequency. The straightening block 105 can thus extend into and out of the straightening groove 52 at a certain frequency. The straightening block 105 presses the wire end 11 against the inner wall of the straightening groove 52, thereby keeping the wire end 11 in a state of extending in the left and right direction, thus straightening the wire end 11 extending outside the magnetic core 2.

[0051] It is conceivable that the straightening groove 52 has two flat surfaces and an arc surface connecting the two flat surfaces. The arc surface and the two flat surfaces are parallel to each other in the left-right direction, and the radius corresponding to the arc surface is equal to the radius of the enameled wire 1. The two flat surfaces form an angle, and this angle is offset in a forward and upward direction. This angle direction is parallel to the driving direction of the fourth linear drive mechanism 104. The straightening block 105 is provided with a straightening part 1051, which can extend into the straightening groove 52. When the fourth linear drive mechanism 104 drives the straightening block 105 to move in the direction of the straightening groove 52, the straightening part 1051 extends into the straightening groove 52, and the straightening part 1051 can press the wire end 11 onto the arc surface, thereby straightening the length direction of the wire end 11 to the left-right direction.

[0052] Reference Figure 1 In some embodiments, there are two fourth linear drive mechanisms 104 and two straightening blocks 105. Both fourth linear drive mechanisms 104 are connected to the front mold 4, and the output ends of the two fourth linear drive mechanisms 104 are respectively connected to the two straightening blocks 105. When the front mold 4 moves, the movement of the front mold 4 carries the two fourth linear drive mechanisms 104 and the two straightening blocks 105, thereby bringing the two fourth linear drive mechanisms 104 and the two straightening blocks 105 closer to the rear mold 5. The two straightening blocks 105 are driven by the two fourth linear drive mechanisms 104 respectively, so that the movement between the two straightening blocks 105 does not interfere with each other, ensuring the effect of the straightening blocks 105 pressing the wire ends 11.

[0053] The first linear drive mechanism 101, the second linear drive mechanism 102, the third linear drive mechanism 72, and the fourth linear drive mechanism 104 can all be cylinders, hydraulic cylinders, or lead screw pairs. In this embodiment, the third linear drive mechanism 72 is a lead screw pair. The output end of the lead screw pair is connected to a connecting plate 721 with a square cross-section. The axial direction of the connecting plate 721 extends in the left-right direction. The push block 71 is provided with a connecting hole, which extends in the left-right direction. The size of the connecting hole is adapted to the outer dimensions of the connecting plate 721. The connecting plate 721 is inserted into the connecting hole of the pusher device 7, so that the connecting plate 721 and the push block 71 can move forward and backward synchronously.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
