Description
Technical Field
[0001] The invention belongs to the technical field of winding machines, and in particular relates to a tension compensation winding machine for a transformer. Background Art
[0002] The tension compensation winding machine is a device that can automatically adjust the tension according to the material, wire diameter and winding speed of the wire during the winding process to ensure that the tension is always kept within the appropriate range. It mainly achieves this function through the tension compensation device, which can sense and respond to changes in the wire tension, thereby automatically adjusting the tension. By maintaining a stable tension, the tension compensation winding machine can ensure that the wire is evenly and tightly arranged during the winding process, thereby improving the winding quality. The tension compensation winding machine is widely used in the winding production of transformers.
[0003] During the winding process of the transformer, the copper wire needs to pass through the conductor structure first, and then be wound onto the transformer mounted on the rotating shaft. In order to ensure that the copper wire is evenly distributed from left to right on the transformer, the conductor structure needs to reciprocate left and right. However, when the conductor structure moves left and right, the copper wire will be driven synchronously by the conductor structure. Since the part where the copper wire is connected to the conductor structure moves before the part where the copper wire is connected to the transformer, the copper wire will be tilted in the area between the conductor structure and the transformer; this tilted state will cause the tension of the copper wire to change. Specifically, when the copper wire is tilted, its tension will increase. During the reciprocating motion of the conductor structure, when the tilt angle between the conductor structure and the copper wire changes from large to small, the tension of the copper wire will decrease. This constant change in tension makes it impossible to maintain the balance of the copper wire tension during the entire winding process, thereby affecting the quality of the normal winding of the transformer. Summary of the invention
[0004] The object of the present invention is to provide a tension-compensated winding machine for a transformer, so as to solve the problem raised in the above-mentioned background technology that during the transformer winding process, the conductor moves left and right, causing the copper wire to tilt and causing the tension of the copper wire to change, thereby affecting the transformer winding quality.
[0005] To achieve the above object, the present invention provides the following technical solution: A tension compensation winding machine for a transformer, comprising a machine body and a guide mechanism with a horizontal reciprocating motion structure; the guide mechanism is placed on the wire inlet side of the machine body; It also includes a compensation mechanism; the compensation mechanism is placed between the machine body and the guide mechanism. During processing, the transformer to be wound is installed on the machine body, and then the copper wire passes through the guide mechanism, passes through the top of the compensation mechanism, and finally is wound on the transformer. The compensation mechanism is composed of a support member and a compensation component installed inside the support member, the middle area of the compensation component is inclined, and the connection between the top of one end of the compensation component and the bottom of the other end and the middle area is protruding toward the outside of the compensation component; A transmission assembly is also provided outside the guide mechanism, and the transmission assembly is sleeved on the end of the compensation assembly. A flip assembly is also fixed at the top of the compensation assembly, and the transmission assembly drives the flip assembly to flip when switching between forward and reverse rotations. When the guide mechanism moves to the far left, it will move in the opposite direction to the right. At this time, the inclination angle between the copper wire and the guide mechanism will change from large to small, that is, the copper wire that was originally tilted and stretched will be briefly relaxed. Fig. 9 The tension of the "Ⅱ" part changes. At this time, due to the reverse movement of the guide mechanism, the transmission component can flip the flip component to a certain angle, and then the flip component flips the compensation component to a certain angle, changing the inclination of the two ends of the compensation component, so that the changed compensation component can push the relaxed copper wire upward to compensate for the tension of the copper wire reduced due to relaxation, that is, Fig.10 The tension changes in the "Ⅱ" part; When the inclination angle between the guide mechanism and the copper wire changes from small to large again, that is, Fig. 9 In the "III" part, the copper wire passes through the end of the compensation component and moves toward the middle area of the compensation component. At this time, the flipped compensation component as a whole can reduce and compensate for the tension of the copper wire that increases due to the increase in the inclination angle. When the guide mechanism moves to the far right, it will continue to move in the opposite direction to the left. The same as the above principle, the subsequent tension compensation is achieved by flipping the compensation component again.
[0006] As a preferred technical solution in the present invention, the compensation component includes an inclined compensation shaft, a downwardly inclined guide part 1 is formed at the bottom of one end of the compensation shaft, and a compensation part is also formed at the bottom of the compensation shaft, the lowest point of the compensation part is connected to the lowest point of the guide part 1, and an upwardly inclined guide part 2 is formed at the top of the other end of the compensation shaft. In the initial state, the copper wire will slide downward along the direction of the compensation shaft. At this time, the slope of the copper wire and the guide mechanism component gradually increases, and the tension compensation of the copper wire can be achieved through the compensation shaft; a connecting shaft with the same inclination slope as itself is fixed at the end faces of both ends of the compensation shaft, so when the connecting shaft rotates 180°, the guide part 1 will rotate to the direction facing upward, and the guide part 2 will rotate to the direction facing downward, and the guide part 1 as a whole will present a state of being inclined upward toward the other end of the compensation shaft. At this time, the guide mechanism is in a state of moving from the leftmost side to the rightmost side, and at this time, the tension of the copper wire is gradually reduced, so that the purpose of increasing the tension compensation can be achieved through the flipped guide part 1. A connecting block is fixed on the end face of the connecting shaft at the other end of the compensation shaft, and the connecting block is fixedly connected to the flip assembly.
[0007] As a preferred technical solution in the present invention, the guide mechanism includes an outer bracket and a servo motor installed on the top side of the outer bracket, the output end of the servo motor is connected to a screw rod penetrating the outer bracket, and the screw rod is transmission-connected to a guide platform, wherein the top of the guide platform has a hole for the copper wire to pass through, and the guide platform is driven by the screw rod to perform horizontal reciprocating motion to achieve the purpose of evenly winding the copper wire on the transformer, and in order to ensure the horizontal movement of the guide platform and avoid synchronous rotation with the screw rod, a guide column penetrating the guide platform is also provided in the outer bracket. This structure is similar to the existing conventional linear guide rail, so it will not be further described here. The guide platform is located on the inner side of the outer bracket, wherein the end of the screw rod passes through the outside of the outer bracket, and the transmission assembly is connected to the end of the outer bracket in a transmission manner. When the servo motor drives the screw rod to rotate, the screw rod will drive the guide platform to rotate synchronously, and drive the transmission assembly to rotate synchronously as well. At the same time, the transmission assembly drives the flipping assembly to complete the turning of the compensation shaft. After the turning is completed, the flipping assembly no longer rotates. Only when the servo motor rotates in the opposite direction will it drive the transmission assembly to drive the flipping assembly to rotate in the opposite direction. After the reverse turning, the flipping assembly no longer rotates, and the transmission assembly idles as a whole. The entire compensation process can be achieved by only a single servo motor.
[0008] As a preferred technical solution in the present invention, the transmission assembly includes a driving gear fixed to the end of the screw rod, and a transmission gear sleeved on the outside of the connecting block. The driving gear and the transmission gear are sleeved on the outside of the driving gear and the transmission gear. The driving gear receives the rotation of the screw rod, and at the same time drives the transmission belt to drive the transmission gear to rotate. The screw rod can be reversed under the action of the servo motor. Similarly, the transmission gear can also be reversed. The forward and reverse rotation of the transmission gear is used to realize the flipping and steering of the compensation shaft.
[0009] As a preferred technical solution in the present invention, the flip assembly includes a collar, which is provided with a mounting hole sleeved on the end of the connecting block. In order to ensure the tight connection between the two, a pin or other structure can be used to penetrate and lock the connection between the two. The outer surface of the collar is provided with two placement grooves at equal angles, that is, the angle between the two placement grooves is 180°. A forward dial plate and a reverse dial plate are respectively provided at the same side wall position inside the two placement grooves. The forward dial plate and the reverse dial plate are both rotatably connected to the bottom end surface of the placement groove; a single toggle block is fixed on the inner wall of the transmission gear, and the toggle block pushes the reverse dial plate when it rotates clockwise, and pushes the forward dial plate when it rotates counterclockwise; The outer part of the collar is also provided with a lifting block, the thickness of which increases from top to bottom, and a moving groove for the toggle block to pass through is provided on the lower outer surface of the lifting block, the depth of the middle position of the moving groove is greater than the depth of the positions on both sides of the moving groove, and the thickness of the toggle block is less than the depth of the middle position of the moving groove, Figure 1 and Figure 5 When the transmission gear rotates clockwise, the guide platform will be moved to the left by the screw rod. At this time, the toggle block will also push the reversing plate in a clockwise direction. At this time, the side of the reversing plate is against the inner wall of the placement groove, thereby pushing the collar to rotate. When the collar rotates, it will synchronously drive the connecting block to rotate, and the connecting block will drive the connecting shaft and the compensation shaft to rotate. During the rotation of the reversing plate and the collar, the reversing plate will be lifted by the lifting block until the reversing plate is lifted and moved to the middle position of the lifting block, that is, Figure 5 In the position of the forward dial plate, since the height of the toggle block is lower than the middle depth of the lifting block, the reverse dial plate is separated from the toggle block. At this time, the collar and the connecting block rotate 180 degrees. At this time, the subsequent rotation of the toggle block no longer contacts the forward dial plate, that is, the transmission gear is driven by the transmission belt to rotate normally, but the entire compensation assembly no longer rotates, and the original forward dial plate will move to the position under the rotation of the collar. Figure 5 The position of the reverse dial plate in the middle is realized to interchange the positions of the forward dial plate and the reverse dial plate, and under the continuous rotation of the toggle block, the toggle block will contact the forward dial plate and squeeze the forward dial plate. At this time, the forward dial plate rotates toward the other side wall of the placement slot until the forward dial plate is no longer in contact with the transmission gear, and the rotating forward dial plate does not press against the placement slot, thereby not pushing the collar, thereby ensuring that after the transmission gear rotates the collar 180°, it will not continue to drive the collar to rotate; when the guide platform moves to the right, the servo motor needs to reverse, and at this time the lead screw, drive gear, and transmission gear also reverse, and drive the transmission gear to reverse, and when the transmission gear reverses, it will push the forward dial plate, and the forward dial plate will press against one side inner wall of the placement slot, thereby driving the collar to rotate, and when the collar rotates, it drives the connecting block to reverse again, and the reverse dial plate that was previously in the middle position below the lifting block is brought back again Figure 5 The positive rotation dial plate is pushed by the dial block to the middle position below the lifting block, that is, Figure 5 After the gear reaches the middle position, it no longer contacts the toggle block, and the transmission gear will contact the reversing paddle during continuous reversal. At this time, the reversing paddle will also rotate when squeezed by the toggle block until it no longer contacts the toggle block, thereby adjusting the steering direction of the compensation shaft according to the change in the lateral movement direction of the guide mechanism.
[0010] As a preferred technical solution in the present invention, a connecting column is fixedly provided on the inner bottom end surface of each of the placement grooves, and the two connecting columns are respectively movably connected to the forward rotation dial plate and the reverse rotation dial plate. Therefore, when the forward rotation dial plate and the reverse rotation dial plate are pushed by the toggle block, they can adapt to the thickness change of the lifting block along the lifting and lowering of the connecting column. The bottom of the forward rotation dial plate and the reverse rotation dial plate are both provided with a tension spring sleeved on the connecting column, wherein the setting of the tension spring can automatically rebound when the forward rotation dial plate or the reverse rotation dial plate is pushed from the thickest position of the lifting block to the thinnest position, thereby ensuring that the forward rotation dial plate and the reverse rotation dial plate are always in contact with the lifting block.
[0011] As a preferred technical solution in the present invention, a retaining spring is also installed on the top of the connecting column. The setting of the retaining spring can avoid the separation of the forward rotation plate and the reverse rotation plate. The retaining spring and the connecting column are both metal components.
[0012] As a preferred technical solution in the present invention, the horizontal plane at the bottom of the movable groove and the bottom of the toggle block are on the same horizontal plane, thereby ensuring that the toggle block will not be blocked by the lifting block during rotation. The support member is two symmetrically arranged mounting brackets, and the top of the mounting bracket is inclined toward the guide mechanism. The movable groove is fixedly connected to the surface of the mounting bracket, and can be installed by spot welding, bolts, etc.
[0013] As a preferred technical solution in the present invention, the body includes a base and a chassis installed at one end of the top of the base. A motor is arranged in the chassis, and a rotating shaft is installed on the output shaft of the motor. During processing, the transformer to be wound is sleeved on the rotating shaft, and the transformer is fixed on the rotating shaft with the help of a dedicated tool. A thimble part is installed at the other end of the top of the base, and the thimble part presses the end of the rotating shaft to ensure the normal rotation of the rotating shaft, wherein the thimble part consists of a mounting seat and a thimble with a thread passing through the top of the mounting seat. When the winding of the transformer is completed, the thimble is unscrewed to realize the disassembly of the transformer. Since this structure is an existing product, it will not be further described here. The mounting bracket is installed on the outside of the rotating shaft and a distance is left between it and the rotating shaft to avoid affecting the normal disassembly and assembly of the transformer.
[0014] As a preferred technical solution in the present invention, the height of the guide platform is equal to the height of the compensation shaft, so that the copper wire passing through the guide platform can be compensated for the tension of the compensation shaft, and the lateral movement distance of the guide platform does not exceed the horizontal projection length of the compensation shaft.
[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, a compensation component is added, which has the function of automatically adjusting according to the change of the copper wire tension. Specifically, the compensation component can make corresponding compensation actions according to the tension fluctuation caused by the change of the inclination angle of the copper wire during the winding process; When the tension of the copper wire increases due to the increase of the inclination angle, the compensation component can effectively reduce the tension of the copper wire, thereby avoiding problems such as copper wire breakage or uneven winding caused by excessive tension; on the contrary, when the inclination angle of the copper wire decreases from large to small, the compensation component can also increase the tension of the copper wire by adjusting its working state, ensuring that the copper wire always maintains an appropriate tension level during the winding process; In the above manner, the compensation component can ensure that the tension of the copper wire during the winding process is always at a constant value, which not only improves the quality and efficiency of the winding, but also significantly enhances the stability and reliability of the entire winding process; this innovative design has brought significant improvements and enhancements to the copper wire winding technology.

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] See also Figures 1 to 10 The present invention provides a technical solution: a tension compensation winding machine for a transformer, comprising body, and A guide mechanism with a horizontal reciprocating motion structure; the guide mechanism is placed on the side of the machine body where the line enters; It also includes a compensation mechanism; the compensation mechanism is placed between the machine body and the guide mechanism. During processing, the transformer to be wound is installed on the machine body, and then the copper wire passes through the guide mechanism, passes through the top of the compensation mechanism, and finally is wound on the transformer. The compensation mechanism is composed of a support and a compensation component 200 installed inside the support. The middle area of the compensation component 200 is inclined, and the connection between the top of one end of the compensation component 200 and the bottom of the other end and the middle area is protruding toward the outside of the compensation component 200. A transmission assembly 300 is also provided outside the guide mechanism. The transmission assembly 300 is sleeved on the end of the compensation assembly 200. A flip assembly 400 is fixed at the top of the compensation assembly 200. The transmission assembly 300 drives the flip assembly 400 to flip when switching between forward and reverse directions. Fig. 9 When the guide mechanism moves from the initial position to the left, that is, from "0", the guide mechanism moves first, and then drives the copper wire to move. One end of the copper wire is wound with the transformer, and the other end is connected to the guide mechanism. Therefore, the moving speed of one end of the copper wire is less than that of the other end, and the copper wire will tilt. At this time, the copper wire is stretched and the tension in the tilted area becomes larger, that is, Fig. 9 The movement of the "Ⅰ" part is the change of tension, refer to Fig.10 When the tension of the copper wire increases, the tension of the copper wire is reduced by the compensation component 200, that is, Fig.10 The tension changes in the "Ⅰ" part; When the guide mechanism moves to the far left, it will move in the opposite direction to the right. At this time, the inclination angle between the copper wire and the guide mechanism will change from large to small, that is, the copper wire that was originally tilted and stretched will be briefly relaxed. Fig. 9The tension of the "Ⅱ" part changes. At this time, due to the reverse movement of the guide mechanism, the transmission component 300 can flip the flip component 400 to a certain angle, and then the flip component 400 can flip the compensation component 200 to a certain angle, changing the inclination of the two ends of the compensation component 200, so that the changed compensation component 200 can push the relaxed copper wire upward to compensate for the tension of the copper wire reduced due to relaxation, that is, Fig.10 The tension changes in the "Ⅱ" part; When the inclination angle between the guide mechanism and the copper wire changes from small to large again, that is, Fig. 9 In the middle "III" part, the copper wire passes through the end of the compensation component 200 and moves toward the middle area of the compensation component 200. At this time, the flipped compensation component 200 as a whole can reduce and compensate for the tension of the copper wire that increases due to the increase in the inclination angle. When the guide mechanism moves to the far right, it will continue to move in the opposite direction to the left. The same as the above principle, the subsequent tension compensation is achieved by flipping the compensation component 200 again.
[0020] In this embodiment, the compensation component 200 includes an inclined compensation shaft 201, a downwardly inclined guide portion 202 is formed at the bottom of one end of the compensation shaft 201, and a compensation portion 201a is also formed at the bottom of the compensation shaft 201. The lowest point of the compensation portion 201a is connected to the lowest point of the guide portion 202, and an upwardly inclined guide portion 203 is formed at the top of the other end of the compensation shaft 201. In the initial state, the copper wire will slide downward along the direction of the compensation shaft 201. At this time, the slope of the copper wire and the guide mechanism component gradually increases, and the tension compensation of the copper wire can be achieved through the compensation shaft 201; the end surfaces of both ends of the compensation shaft 201 are fixed with The connecting shaft 204 has a slope equal to its own, so when the connecting shaft 204 rotates 180°, the guide part 1 202 will rotate to face upward, and the guide part 203 will rotate to face downward, and the guide part 1 202 as a whole will be in a state of being tilted upward toward the other end of the compensation shaft 201. At this time, the guide mechanism is moving from the leftmost side to the rightmost side, and the tension of the copper wire is gradually reduced, so that the purpose of increasing the tension compensation can be achieved by turning the guide part 1 202. Subsequently, when the copper wire and the guide mechanism are separated again, the inclination angle between the two increases, and the tension of the copper wire increases again. At this time, refer to Figure 4 The tension of the copper wire can be reduced by tilting the compensation part 201a downward to achieve balanced compensation of the tension of the copper wire. A connecting block 205 is fixedly provided on the end surface of the connecting shaft 204 at the other end of the compensation shaft 201, and the connecting block 205 is fixedly connected to the flip assembly 400.
[0021] In this embodiment, the guide mechanism includes an outer bracket 107, and a servo motor 108 installed on the top side of the outer bracket 107. The output end of the servo motor 108 is connected to a screw rod 106 that passes through the outer bracket 107. The screw rod 106 is connected to a guide platform 105 in a transmission manner. The top of the guide platform 105 has a hole for the copper wire to pass through. The guide platform 105 is driven by the screw rod 106 to perform horizontal reciprocating motion to achieve the purpose of evenly winding the copper wire on the transformer. In order to ensure the horizontal movement of the guide platform 105 and avoid synchronous rotation with the screw rod 106, a guide column that passes through the guide platform 105 is also provided in the outer bracket 107. This structure is similar to the existing conventional linear guide rail, so it will not be further described here. The guide platform 105 is located in the outer bracket 107. , wherein the end of the screw rod 106 passes through the outside of the outer bracket 107, and the transmission assembly 300 is connected to the end of the outer bracket 107. When the servo motor 108 drives the screw rod 106 to rotate, the screw rod 106 will drive the guide platform 105 to rotate synchronously, and drive the transmission assembly 300 to rotate synchronously. At the same time, the transmission assembly 300 drives the flip assembly 400 to complete the steering of the compensation shaft 201. After the steering is completed, the flip assembly 400 no longer rotates. Only when the servo motor 108 rotates in the opposite direction, it will drive the transmission assembly 300 to drive the flip assembly 400 to rotate in the opposite direction. After the reverse steering, the flip assembly 400 no longer rotates, and the transmission assembly 300 is idle as a whole. The entire compensation process can be achieved by only a single servo motor 108.
[0022] In this embodiment, the transmission assembly 300 includes a driving gear 301 fixed to the end of the screw rod 106, and a transmission gear 303 sleeved on the outside of the connecting block 205. The driving gear 301 and the transmission gear 303 are sleeved on the outside with a transmission belt 302. The driving gear 301 receives the rotation of the screw rod 106, and at the same time drives the transmission belt 302 to drive the transmission gear 303 to rotate. The screw rod 106 can be reversed under the action of the servo motor 108. Similarly, the transmission gear 303 can also achieve forward and reverse rotation. The forward and reverse rotation of the transmission gear 303 realizes the flipping and steering of the compensation shaft 201.
[0023] In this embodiment, the flip assembly 400 includes a collar 401, which is provided with a mounting hole 401a that is sleeved on the end of the connecting block 205. In order to ensure the tight connection between the two, a pin or other structure can be used to penetrate and lock the connection between the two. The outer surface of the collar 401 is provided with two placement grooves 401b at equal angles, that is, the angle between the two placement grooves 401b is 180°, and a forward dial plate 403 and a reverse dial plate 404 are respectively provided at the same side wall position inside the two placement grooves 401b. The forward dial plate 403 and the reverse dial plate 404 are both rotatably connected to the bottom end surface of the placement groove 401b; a single toggle block 303a is fixed on the inner wall of the transmission gear 303, and the toggle block 303a pushes the reverse dial plate 404 when it is turned clockwise, and pushes the forward dial plate 403 when it is turned counterclockwise; The outer part of the collar 401 is also provided with a lifting block 402, the thickness of which increases from top to bottom, and a moving groove 402a for the toggle block 303a to pass through is provided on the lower outer surface of the lifting block 402, the depth of the middle position of the moving groove 402a is greater than the depth of the positions on both sides of the moving groove 402a, and the thickness of the toggle block 303a is less than the depth of the middle position of the moving groove 402a, referring to Figure 1 and Figure 5 When the transmission gear 303 rotates clockwise, the guide platform 105 is moved to the left by the screw rod 106. At this time, the toggle block 303a will also push the reversing dial plate 404 in the clockwise direction. At this time, the side of the reversing dial plate 404 is against the inner wall position of the placement groove 401b, thereby pushing the collar 401 to rotate. When the collar 401 rotates, it will synchronously drive the connecting block 205 to rotate, and the connecting block 205 will drive the connecting shaft 204 and the compensation shaft 201 to rotate. During the rotation of the reversing dial plate 404 and the collar 401, the reversing dial plate 404 will be lifted by the lifting block 402 until the reversing dial plate 404 is lifted and moved to the middle position of the lifting block 402, that is, Figure 5 In the position of the middle forward dial plate 403, since the height of the toggle block 303a is lower than the middle depth of the lifting block 402, the reverse dial plate 404 is separated from the toggle block 303a. At this time, the ring 401 and the connecting block 205 rotate 180 degrees. At this time, the subsequent rotation of the toggle block 303a no longer contacts the forward dial plate 403, that is, the transmission gear 303 is normally driven by the transmission belt 302 to rotate, but the entire compensation assembly 200 no longer rotates, and the original forward dial plate 403 will move to the position under the rotation of the ring 401. Figure 5The position of the reverse dial plate 404 is changed to realize the interchange of the positions of the forward dial plate 403 and the reverse dial plate 404. Under the continuous rotation of the toggle block 303a, the toggle block 303a will contact with the forward dial plate 403 and squeeze the forward dial plate 403. At this time, the forward dial plate 403 rotates toward the other side wall of the placement groove 401b until the forward dial plate 403 and the transmission gear 303 are no longer in contact. The rotating forward dial plate 403 does not press against the placement groove 401b, and thus does not push the ring 401. This ensures that after the transmission gear 303 rotates the ring 401 180°, it will not It will continue to drive the collar 401 to rotate; when the guide platform 105 moves to the right, the servo motor 108 needs to reverse, and at this time the screw rod 106, the driving gear 301, and the transmission gear 303 also reverse, and drive the transmission gear 303 to reverse, and when the transmission gear 303 reverses, it will push the forward dial plate 403, and the forward dial plate 403 will abut against the inner wall of one side of the placement groove 401b, thereby driving the collar 401 to rotate, and when the collar 401 rotates, it drives the connecting block 205 to reverse again, and the reverse dial plate 404 that was previously in the middle position below the lifting block 402 is brought back again Figure 5 The positive rotation dial plate 403 is pushed by the dial block 303a to the middle position below the lifting block 402, that is, Figure 5 After reaching the middle position, it no longer contacts the toggle block 303a, and the transmission gear 303 contacts the reversing dial plate 404 during continuous reversal. At this time, the reversing dial plate 404 also rotates when being squeezed by the toggle block 303a until it no longer contacts the toggle block 303a, thereby adjusting the direction of the compensation shaft 201 according to the change in the lateral movement direction of the guide mechanism.
[0024] In this embodiment, a connecting column 405 is fixedly provided on the inner bottom end surface of each placement groove 401b, and the two connecting columns 405 are respectively movably connected to the forward rotation dial plate 403 and the reverse rotation dial plate 404. Therefore, when the forward rotation dial plate 403 and the reverse rotation dial plate 404 are pushed by the toggle block 303a, they can adapt to the thickness change of the lifting block 402 along the lifting and lowering of the connecting column 405. The bottom of the forward rotation dial plate 403 and the reverse rotation dial plate 404 are both provided with a tension spring 407 sleeved on the connecting column 405. The setting of the tension spring 407 can automatically rebound when the forward rotation dial plate 403 or the reverse rotation dial plate 404 is pushed from the thickest position of the lifting block 402 to the thinnest position, thereby ensuring that the forward rotation dial plate 403 and the reverse rotation dial plate 404 are always in contact with the lifting block 402.
[0025] In this embodiment, a retaining spring 406 is also installed at the top of the connecting column 405. The setting of the retaining spring 406 can prevent the forward rotation plate 403 and the reverse rotation plate 404 from being separated. The retaining spring 406 and the connecting column 405 are both made of metal.
[0026] In this embodiment, the bottom horizontal plane of the movable groove 402a and the bottom of the toggle block 303a are on the same horizontal plane, thereby ensuring that the toggle block 303a will not be blocked by the lifting block 402 during rotation. The support member is two symmetrically arranged mounting brackets 104, and the top of the mounting bracket 104 is inclined toward the guide mechanism. The movable groove 402a is fixedly connected to the surface of the mounting bracket 104, and can be installed by spot welding, bolts, etc.
[0027] In this embodiment, the machine body includes a base 100 and a chassis 101 installed at one end of the top of the base 100. A motor is arranged in the chassis 101, and a rotating shaft 102 is installed on the output shaft of the motor. During processing, the transformer to be wound is sleeved on the rotating shaft 102, and then the transformer is fixed on the rotating shaft 102 with the help of a dedicated tool. A thimble part 103 is installed at the other end of the top of the base 100. The thimble part 103 presses the end of the rotating shaft 102 tightly to ensure the normal rotation of the rotating shaft 102, wherein the thimble part 103 is composed of a mounting seat and a thimble with a thread passing through the top of the mounting seat. When the transformer winding is completed, the thimble is unscrewed to realize the disassembly of the transformer. Since this structure is an existing product, it will not be further described here. The mounting bracket 104 is installed on the outside of the rotating shaft 102, and a distance is left between it and the rotating shaft 102 to avoid affecting the normal disassembly and assembly of the transformer.
[0028] In this embodiment, the height of the guide platform 105 is equal to the height of the compensation shaft 201 , so the copper wire passing through the guide platform 105 can be compensated by the tension of the compensation shaft 201 , and the lateral movement distance of the guide platform 105 does not exceed the horizontal projection length of the compensation shaft 201 .
[0029] in Fig. 9 The Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ in the figure are the order of the change of the copper wire tension. Fig.10 Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ are the sequential numbers for compensating for the tension changes of the components.
