A transformer coil tension winding device, a production line having the device, and a method

Abstract

The present invention discloses a tension winding device for a transformer coil, which relates to the technical field of transformers and includes a driving table and a tension control mechanism. By arranging a tension roller that can slide up and down above the wire pay-off reel of the tension control mechanism, the wire comes out from the wire pay-off reel, passes through the tension roller, and then presses down the tension roller. After the tension roller slides down under the pressure of the wire, while compressing the tension spring, it also causes the electric sheet to contact and conduct with the conductive sheet, thereby enabling the rotary motor of the driving table to be in a powered-on state waiting to be started. In this way, on the one hand, it is beneficial for the acting force of the tension spring to resist the wire pressure, making the wire in a taut state, and the acting force of the spring is stable and limited, so it is not easy to make the wire too taut and affect the performance of the transformer; on the other hand, when the tension pressure of the wire becomes smaller (loose) or the wire breaks, the tension spring can also change accordingly, causing the electric sheet and the conductive sheet to no longer contact, disconnecting the rotary motor, and avoiding meaningless winding.

Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and particularly relates to a transformer coil tension winding device. Background Art

[0002] Since the Industrial Revolution in the UK, the development of human society has changed with each passing day. The Industrial Revolution greatly improved labor productivity. Since then, a large number of new things have emerged. Steam engines, internal combustion engines, generators, and transformers are a kind of dividing line, a dividing line of human civilization. They created the First Industrial Revolution and the Second Industrial Revolution. An indispensable part of a transformer is the coil.

[0003] With the development of the times, whether in the production field or the household field, transformers are becoming increasingly important to people's lives. When a transformer operates, it requires a coil. Currently, a power-driven winding machine is used for manufacturing coils. During the winding process, there are strict regulations on how many turns need to be wound. If the coil is not fixed, it is likely to become loose, resulting in an impact on the performance of the transformer. Therefore, when winding the coil, the wire usually needs to be tightened to avoid looseness during winding. However, for beginners, it is difficult to control the tightened state of the winding, that is, it is difficult to control the distance between the wire release coil and the coil skeleton (in the prior art, the wire release coil rotates around the coil skeleton, and the wire released from the wire release coil is wound around the coil skeleton), resulting in the winding breaking or becoming loose. Summary of the Invention

[0004] One of the purposes of the present invention is to solve the problem in the prior art that during the winding of a coil, it is difficult to control the tightened state of the winding, resulting in the winding breaking or becoming loose.

[0005] Another purpose of the present invention is to provide a production line with a transformer coil tension winding device.

[0006] A third purpose of the present invention is to provide a transformer coil tension winding method.

[0007] To achieve the above purpose, the present invention adopts the following technical solution: A transformer coil tension winding device, which includes: a driving table and a tension control mechanism.

[0008] The driving table has: a rotating motor, a fixed disk, a telescopic rod, and a clamping disk.

[0009] The fixed disk is connected to the power end of the rotating motor. The telescopic rod is installed on the fixed disk. The clamping disk is connected to the telescopic end of the telescopic rod. The clamping disk is used for clamping and fixing the coil skeleton.

[0010] The tension control mechanism is arranged above the clamping disc, and the tension control mechanism includes: a wire pay-off reel, a suspension platform, a tension roller, a chute, a slider, and a tension spring.

[0011] The wire pay-off reel is rotatably installed in the tension control mechanism. The suspension platform is arranged above or on the side above the wire pay-off reel. The tension roller is located in the wire passing opening of the suspension platform.

[0012] The chute is arranged on the side groove of the wire passing opening. The slider is slidably connected to the chute. The tension roller is rotatably connected to the slider. A conductive sheet is installed under the chute, and the conductive sheet is electrically connected to the rotating motor. A power-on sheet is installed under the slider. The conductive sheet is located at the lower end of the power-on sheet, and there is a gap between the conductive sheet and the power-on sheet. The tension spring is connected to the slider.

[0013] In the above technical solution, after the coil bobbin is fixed on the clamping disc of the driving platform in the embodiment of the present invention, the wire of the wire pay-off reel in the tension control mechanism is pulled upward, so that the wire passes through the wire passing opening of the suspension platform and is placed on the tension roller. Then, the wire passing through the tension roller is pulled downward, so that the wire is fixed on the coil bobbin. Among them, when the head end of the wire is pulled downward, the part of the wire placed on the tension roller exerts a downward pressure on the tension roller, prompting the tension roller to drive the slider to slide along the chute of the suspension platform, compress the tension spring, and at the same time make the power-on sheet under the slider contact the conductive sheet under the chute, and then make the rotating motor of the driving platform in a powered-on and standby state.

[0014] After the wire is fixed to the coil bobbin, the rotating motor is started, so that the rotating motor drives the fixed disc and the clamping disc to rotate, and then drives the coil bobbin to rotate. At the same time, the telescopic rod drives the clamping disc to slowly move left and right, so that the wire is evenly wound on the coil bobbin.

[0015] Further, in the embodiment of the present invention, the driving platform is installed on the base, and a bracket is also installed on the base. The tension control mechanism is fixed on the bracket.

[0016] Further, in the embodiment of the present invention, the power-on sheet is connected to the power supply through a wire, and the contact surface of the power-on sheet and the conductive sheet is an end surface with raised particles or concave notches. Through the rough contact surface of the power-on sheet and the conductive sheet, on the one hand, good electrical conductivity is achieved when the power-on sheet and the conductive sheet are in contact, and on the other hand, when the tension roller shakes, through the damping of the contact end surface of the power-on sheet and the conductive sheet, it is not easy for the contact surface of the power-on sheet and the conductive sheet to have poor contact.

[0017] Further, in the embodiment of the present invention, the two sides of the tension roller have outwardly protruding edges, and the tension roller has a double-cone structure with diameters decreasing from both sides towards the middle. With this structure, the wire placed on the tension roller is not prone to deviation, which may affect the winding of the coil skeleton and cause uneven winding.

[0018] Furthermore, in the embodiment of the present invention, a cutting mechanism with a telescopic function is also fixed on the bracket, and a cutting knife is connected to the telescopic end of the cutting mechanism.

[0019] Further, in the embodiment of the present invention, a limiting member is connected under the clamping disc. The limiting member has a telescopic head, a limiting plate is installed on the telescopic head, arc-shaped guiding grooves are provided on the limiting plate, the guiding grooves are arc-shaped, and a telescopic spring is installed between the limiting plate and the limiting member.

[0020] When the wire is evenly wound on the coil skeleton, under the action of the telescopic pressure of the telescopic spring of the limiting member, the limiting plate dynamically presses the wire on the coil skeleton. At the same time, through the arc-shaped guiding grooves of the limiting plate, the wire wound on the coil skeleton is restricted from slipping left and right, avoiding uneven distribution of the wire and affecting the performance of the transformer.

[0021] The beneficial effects of the present invention are as follows:

[0022] In the present invention, a tension roller that can slide up and down is arranged above the wire pay-off reel of the tension control mechanism, so that the wire comes out of the wire pay-off reel, passes through the tension roller, and then presses down the tension roller. After the tension roller slides down under the pressure of the wire, while compressing the tension spring, it also causes the electric piece to contact and conduct with the conductive piece, and then the rotating motor of the driving table is in a powered-on standby state. In this way, on the one hand, it is beneficial for the acting force of the tension spring to resist the wire pressure, making the wire in a taut state, and the acting force of the spring is stable and limited, and it is not easy to make the wire too taut and affect the performance of the transformer; on the other hand, when the tension of the wire becomes smaller (loose) or the wire breaks, the tension spring can also change accordingly, so that the electric piece and the conductive piece no longer contact, disconnecting the rotating motor and avoiding meaningless winding. It solves the problem in the prior art that it is difficult to control the taut state of the winding during the winding of the coil, resulting in the occurrence of broken or loose winding.

[0023] To achieve the second above-mentioned purpose, the present invention adopts the following technical solution: A production line, which has the transformer coil tension winding device described in the first above-mentioned object of the invention.

[0024] Further, in the embodiment of the present invention, the production line also has a cleaning tank and a cleaning box.

[0025] Furthermore, in an embodiment of the present invention, the cleaning box has a guide wheel, which is used to guide the wire into the cleaning box. The cleaning box has a fixed table, and the fixed table has a through hole for the wire to pass through. The fixed table is rotatably connected to a rotating sleeve, and the through hole of the rotating sleeve is communicated with the through hole. A brush is installed on the through hole wall of the rotating sleeve. When the wire passes through the through hole of the rotating sleeve, the brush is driven to clean the wire by rotating the rotating sleeve.

[0026] Furthermore, in an embodiment of the present invention, a tooth groove is provided on the outer surface of the rotating sleeve, and a driving gear is meshed with the tooth groove, and the driving gear is connected to the power end of the driving motor.

[0027] In the current prior art, an electrically driven winding machine is used for the manufacture of the coil, but its operation is relatively cumbersome, and it is not convenient to install and disassemble the coil barrel. In addition, due to the long-term use of the winding machine, impurities are easily accumulated, and the impurities will be mixed on the wire, resulting in a decrease in its quality in later use. Therefore, it is necessary to clean the wire. The present invention uses a guide wheel to guide the wire into a cleaning box, soak it in the liquid in the cleaning box, and then start the driving motor to drive the rotating sleeve to rotate, thereby driving the brush to rotate, and brushing the circumference of the wire to avoid impurity accumulation during winding, which affects the quality of the transformer.

[0028] Furthermore, in an embodiment of the present invention, the cleaning box has a channel for the wire to pass through, and the upper and lower ends of the channel are provided with cleaning blocks, and the cleaning blocks are used to wipe off water stains on the wire.

[0029] The left side of the cleaning block is connected to a first sliding plate, the right side of the first sliding plate has an elastic notch, and the first sliding plate is connected to a pressure spring. The right side of the cleaning block is connected to a second sliding plate, the left side of the second sliding plate has an engagement rod, the engagement rod has a ball that matches the elastic notch, and the right side of the second sliding plate is connected to a telescopic motor.

[0030] After the lines are cleaned in the cleaning box, there will be water stains, so they need to be wiped off. The present invention allows the lines to pass slowly through the channel of the cleaning box. When the lines pass through, the lines contact the cleaning block, and the cleaning block and the water stains on the lines are wiped off.

[0031] After the cleaning block is wiped for a long time, the water absorbed by the cleaning block will be saturated, affecting the erasing effect. For this reason, the present invention starts the telescopic motor to push the second sliding plate close to the first sliding plate, squeeze the cleaning block, and make the water of the cleaning block flow into the water tank in the channel of the cleaning box. After the cleaning block is squeezed, the ball of the engagement rod is stuck in the elastic notch of the first sliding plate. After the telescopic motor is reset, the second sliding plate drives the first sliding plate to retreat. At this time, the cleaning block wipes the lines. After that, when the second sliding plate drives the first sliding plate to retreat to the set position, the pressure spring affected by the first sliding plate pulls the first sliding plate, so that the ball of the engagement rod is separated from the elastic notch, driving the first sliding plate to reset quickly, thereby making the relatively dry cleaning block quickly wipe the lines. Because the cleaning block is squeezed out of water, the slowly moving lines will inevitably be wet, and the clamped cleaning block is actually limited in dryness, and it is difficult to wipe the water of the lines at one time. Therefore, when the cleaning block is reset by pulling the pressure spring, the cleaning block is unfolded and relatively dry, and the water of the lines can be effectively wiped. Creates a self-drying wipe effect.

[0032] To achieve the third of the above-mentioned objectives, the present invention adopts the following technical solution: a transformer coil tension winding method, applied to the transformer coil tension winding device described in one of the above-mentioned invention objectives or the production line described in the second of the above-mentioned invention objectives, wherein the method comprises the following steps:

[0033] After the coil frame is fixed on the clamping plate of the driving platform, the wire of the unwinding coil in the tension control mechanism is pulled upward, so that the wire passes through the wire passing port of the hanging platform and rests on the tension roller, and then the wire passing through the tension roller is pulled downward to fix the wire on the coil frame;

[0034] When the head end of the wire is pulled downward, the wire part resting on the tension roller exerts downward pressure on the tension roller, prompting the tension roller to drive the slider to slide along the slide slot of the hanging platform, compressing the tension spring, and at the same time making the power sheet under the slider contact with the conductive sheet under the slide slot, thereby putting the rotating motor of the driving platform in a power-on waiting to start state;

[0035] After the wire is fixed to the coil frame, the rotating motor is started, so that the rotating motor drives the fixed disk and the clamping disk to rotate, and then drives the coil frame to rotate. At the same time, the telescopic rod drives the clamping disk to move slowly left and right, so that the wire is evenly wound on the coil frame.

[0036] Furthermore, in an embodiment of the present invention, in the above steps, when the lines are evenly wound on the coil frame, the telescopic pressure of the telescopic spring of the limiting member causes the limiting plate to dynamically squeeze the lines on the coil frame. At the same time, the arc-shaped guide groove of the limiting plate limits the left and right sliding of the lines wound on the coil frame, thereby avoiding uneven distribution of the lines and affecting the performance of the transformer.

[0065] For the purposes of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are set forth in order to provide a thorough understanding of the embodiments. However, it is obvious that, for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known transformer coil tension winding methods and structures are not described in detail so as not to unnecessarily obscure these embodiments. Additionally, all embodiments can be used in combination with each other.

[0066] Embodiment 1:

[0067] A transformer coil tension winding device, wherein, as Figure 1 shown, includes: a driving table 10 and a tension control mechanism 20.

[0068] The driving table 10 has: a rotating motor 11, a fixed disk 12, a telescopic rod 13, and a clamping disk 14.

[0069] The fixed disk 12 is connected to the power end of the rotating motor 11. The telescopic rod 13 is installed on the fixed disk 12. The clamping disk 14 is connected to the telescopic end of the telescopic rod 13. The clamping disk 14 is used to clamp and fix the coil skeleton 100.

[0070] As Figure 2 , 3 shown, the tension control mechanism 20 is arranged above the clamping disk 14. The tension control mechanism 20 has: a wire pay-off reel 21, a hanging table 22, a tension roller 23, a chute 24, a slider 25, and a tension spring 26.

[0071] The wire pay-off reel 21 is rotatably installed in the tension control mechanism 20. The hanging table 22 is arranged above or at the upper side of the wire pay-off reel 21. The tension roller 23 is located in the wire passing opening of the hanging table 22.

[0072] The chute 24 is arranged on the side groove of the wire passing opening. The slider 25 is slidably connected to the chute 24. The tension roller 23 is rotatably connected to the slider 25. A conductive sheet 241 is installed under the chute 24. The conductive sheet 241 is electrically connected to the rotating motor 11. A power receiving sheet 251 is installed under the slider 25. The conductive sheet 241 is located at the lower end of the power receiving sheet 251. There is a gap between the conductive sheet 241 and the power receiving sheet 251. The tension spring 26 is connected to the slider 25.

[0073] Implementation steps:

[0074] When in use, fix the coil skeleton 100 on the clamping disk 14 of the driving table 10. Then, pull up the wire of the wire pay-off reel 21 in the tension control mechanism 20 so that the wire passes through the wire passing opening of the hanging table 22 and rests on the tension roller 23. Then, pull down the wire passing through the tension roller 23 so that the wire is fixed on the coil skeleton 100. Among them, as Figure 4As shown, when the head end of the wire is pulled downward, the part of the wire resting on the tension roller 23 exerts a downward pressure on the tension roller 23, causing the tension roller 23 to drive the slider 25 to slide along the chute 24 of the suspension platform 22, compressing the tension spring 26. At the same time, the energized piece 251 under the slider 25 comes into contact with the conductive piece 241 under the chute 24, and then the rotary motor 11 of the driving platform 10 is in a powered-on and standby state.

[0075] After the wire is fixed to the coil bobbin 100, the rotary motor 11 is started, causing the rotary motor 11 to drive the fixed disk 12 and the clamping disk 14 to rotate, and then driving the coil bobbin 100 to rotate. At the same time, the telescopic rod 13 drives the clamping disk 14 to move slowly left and right, so that the wire is evenly wound around the coil bobbin 100.

[0076] In the present invention, a vertically slidable tension roller 23 is provided above the wire pay-off reel 21 of the tension control mechanism 20, so that the wire coming out of the wire pay-off reel 21 passes through the tension roller 23 and presses down on the tension roller 23. After the tension roller 23 slides down under the pressure of the wire, while compressing the tension spring 26, it also causes the energized piece 251 to come into contact and conduct with the conductive piece 241, and then the rotary motor 11 of the driving platform 10 is in a powered-on and standby state. In this way, on the one hand, it is beneficial for the acting force of the tension spring 26 to resist the wire pressure, so that the wire is in a taut state, and the spring acting force is stable and limited, and it is not easy to make the wire too taut and affect the performance of the transformer; on the other hand, when the tension pressure of the wire becomes smaller (looser) or the wire breaks, the tension spring 26 can also change accordingly, so that the energized piece 251 and the conductive piece 241 no longer contact, disconnecting the rotary motor 11 and avoiding meaningless winding. It solves the problem in the prior art that it is difficult to control the taut state of the winding during coil winding, resulting in the winding breaking or loosening.

[0077] As Figure 1 shown, the driving platform 10 is installed on a base (not shown), and a bracket is also installed on the base. The tension control mechanism 20 is fixed on the bracket.

[0078] The energized piece 251 is connected to the power supply through a wire. The contact surface between the energized piece 251 and the conductive piece 241 is an end face with raised particles or a concave notch. Through the rough contact surface between the energized piece 251 and the conductive piece 241, on the one hand, good conductivity is achieved when the energized piece 251 contacts the conductive piece 241; on the other hand, when the tension roller 23 shakes, through the damping of the contact end face between the energized piece 251 and the conductive piece 241, it is not easy for the contact surface between the energized piece 251 and the conductive piece 241 to have poor contact.

[0079] As Figure 3As shown, both sides of the tension roller 23 have outwardly protruding edges, and the tension roller 23 has a double-cone structure with the diameters on both sides decreasing towards the middle. With this structure, the wire placed on the tension roller 23 is not likely to shift, which affects the winding of the coil skeleton 100 and causes uneven winding.

[0080] As Figure 1 shown, a cutting mechanism 30 with a telescopic function is also fixed on the bracket, and a cutting knife 31 is connected to the telescopic end of the cutting mechanism 30.

[0081] As Figure 1 、 5 shown, a limiting member 40 is connected under the clamping disc 14. The limiting member 40 has a telescopic head 41, a limiting plate 42 is installed on the telescopic head 41, undulating guide grooves 421 are provided on the limiting plate 42, the guide grooves 421 are arc-shaped, and a telescopic spring 43 is installed between the limiting plate 42 and the limiting member 40.

[0082] When the wire is evenly wound on the coil skeleton 100, under the action of the telescopic pressure of the telescopic spring 43 of the limiting member 40, the limiting plate 42 dynamically presses the wire on the coil skeleton 100. At the same time, through the arc-shaped guide grooves 421 of the limiting plate 42, the left and right sideslip of the wire wound on the coil skeleton 100 is restricted, avoiding uneven distribution of the wire and affecting the performance of the transformer.

[0083] Embodiment 2:

[0084] A production line, in which, as Figure 6 shown, it has the transformer coil tension winding device in the first embodiment above.

[0085] As Figure 6 、 7 shown, the production line also has a cleaning tank 50 and a cleaning box 60. The cleaning tank 50 has guide wheels, which are used to guide the wire into the cleaning tank 50. There is a fixed table 51 in the cleaning tank 50. The fixed table 51 has a through hole for the wire to pass through. The fixed table 51 is rotatably connected with a rotating sleeve 52. The through port of the rotating sleeve 52 communicates with the through hole. A brush 53 is installed on the wall surface of the through port of the rotating sleeve 52. When the wire passes through the through port of the rotating sleeve 52, the brush 53 is driven to clean the wire by rotating the rotating sleeve 52.

[0086] Tooth grooves are provided on the outer surface of the rotating sleeve 52, a driving gear 54 meshes with the tooth grooves, and the driving gear 54 is connected to the power end of a driving motor 55.

[0087] In the current prior art, a power-driven wire winder is used for manufacturing coils. However, its operation is rather troublesome, and it is not convenient to install and disassemble the coil bobbin. Moreover, due to the long-term use of the wire winder, impurities are likely to accumulate, and the impurities will be doped on the wire, resulting in a reduction in the quality of its later use. Therefore, it is necessary to clean the wire. In the present invention, a guide wheel is used to guide the wire into the cleaning tank 50, soak it in the liquid in the cleaning tank 50, and then start the drive motor 55 to drive the rotating sleeve 52 to rotate, thereby driving the brush 53 to rotate and brush the circumferential surface of the wire to avoid the accumulation of impurities during winding and affect the quality of the transformer.

[0088] Embodiment Three:

[0089] An assembly line, which has the same characteristic structure and its technical effects as those in Embodiment Two above. Among them, as Figure 6 、 8 shown, the cleaning tank 60 has a passage for the wire to pass through, and cleaning blocks 61 are provided at the upper and lower ends of the passage. The cleaning blocks 61 are used to dry the water stains on the wire.

[0090] A first sliding plate 62 is connected to the left side of the cleaning block 61. An elastic notch 63 is provided on the right side of the first sliding plate 62, and a compression spring 64 is connected to the first sliding plate 62. A second sliding plate 65 is connected to the right side of the cleaning block 61. An engaging rod 66 is provided on the left side of the second sliding plate 65, and a sphere that cooperates with the elastic notch 63 is provided on the engaging rod 66. A telescopic motor 67 is connected to the right side of the second sliding plate 65.

[0091] After the wire is cleaned in the cleaning tank 50, there will be water stains, so it is necessary to wipe them off. In the present invention, the wire slowly passes through the passage of the cleaning tank 60. When the wire passes through, the wire contacts the cleaning block 61, and the cleaning block 61 wipes off the water stains on the wire.

[0092] After the cleaning block 61 has been wiped for a long time, the water absorbed by the cleaning block 61 will be saturated, affecting the wiping effect. For this reason, as Figure 9 、 10As shown in the figure, the present invention starts the telescopic motor 67, pushes the second sliding plate 65 closer to the first sliding plate 62, squeezes the cleaning block 61, so that the water in the cleaning block 61 flows into the water tank in the channel of the cleaning box 60. After the cleaning block 61 is squeezed, the sphere of the engaging rod 66 is simultaneously caught in the elastic notch 63 of the first sliding plate 62. After the telescopic motor 67 resets, the second sliding plate 65 drives the first sliding plate 62 to retreat. At this time, the cleaning block 61 wipes the line. After that, when the second sliding plate 65 drives the first sliding plate 62 to retreat to the set position, the pressure spring 64 affected by the first sliding plate 62 pulls the first sliding plate 62, so that the sphere of the engaging rod 66 disengages from the elastic notch 63, driving the first sliding plate 62 to quickly reset, and then enabling the relatively dry cleaning block 61 to quickly wipe the line. Because after the cleaning block 61 is squeezed out of water, the slowly moving line will inevitably get wet, and the clamped cleaning block 61 is actually limited in dryness and it is difficult to wipe the water on the line at one time. Therefore, when the cleaning block 61 is pulled back by the pressure spring 64, the cleaning block 61 unfolds and is relatively dry, and can effectively wipe the water on the line, forming a self-drying wiping effect.

[0093] Embodiment 4:

[0094] A method for tension winding of a transformer coil, which is applied to the transformer coil tension winding device in the above-mentioned Embodiment 1 or the production line in Embodiment 2 or 3, and includes the following steps:

[0095] After fixing the coil skeleton 100 on the clamping disc 14 of the driving table 10, pull up the line of the wire reel 21 in the tension control mechanism 20, so that the line passes through the wire passing port of the hanging table 22 and rests on the tension roller 23. Then pull down the line passing through the tension roller 23 so that the line is fixed on the coil skeleton 100.

[0096] Among them, when the head end of the line is pulled down, the part of the line resting on the tension roller 23 exerts a downward pressure on the tension roller 23, prompting the tension roller 23 to drive the slider 25 to slide along the chute 24 of the hanging table 22, compressing the tension spring 26, and at the same time making the power-on piece 251 under the slider 25 contact the conductive piece 241 under the chute 24, and then making the rotation motor 11 of the driving table 10 in the power-on and waiting-to-start state.

[0097] After the line is fixed to the coil skeleton 100, start the rotation motor 11, so that the rotation motor 11 drives the fixed disc 12 and the clamping disc 14 to rotate, and then drives the coil skeleton 100 to rotate. At the same time, the telescopic rod 13 drives the clamping disc 14 to slowly move left and right, so that the line is evenly wound on the coil skeleton 100.

[0098] In the above steps, when the wire is evenly wound around the coil bobbin 100, under the action of the expansion and contraction pressure of the expansion and contraction spring 43 of the limiting member 40, the limiting plate 42 dynamically presses the wire on the coil bobbin 100. At the same time, through the arc-shaped guide groove 421 of the limiting plate 42, the left and right sidesliding of the wire wound around the coil bobbin 100 is restricted, avoiding uneven distribution of the wire and affecting the performance of the transformer.

[0099] Although the above-described illustrative specific embodiments of the present invention have been described to enable those skilled in the art to understand the present invention, the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, all inventions made using the concept of the present invention are within the scope of protection.
