Description

Technical Field

[0001] This invention relates to the field of automatic winding technology for transformer coils, specifically to an automated winding processing device based on transformer production. Background Technology

[0002] Currently, transformers are an indispensable and very important piece of electrical equipment in the power system, especially small and medium-sized transformers, which are widely used in the power system. When abnormalities occur during the winding process of EI / EE transformers, the wire feeding roller will continue to feed due to rotational inertia, causing the wires to become tangled and knotted. It takes a long time to sort out and restore them. Different wire diameters require the replacement of corresponding guide nozzles and guide components, making the changeover and debugging cumbersome and the production efficiency of small batches and multiple varieties low. Furthermore, during the winding process, the existing conventional tension system can only control the tension magnitude and cannot eliminate the internal stress of the coiling that the enameled wire carries when it leaves the factory. This results in uneven arrangement of conductor layers after winding, jumper bulges, loose windings, and poor accuracy in the number of turns and winding dimensions. During the production and winding of conductors, if there are particles or oil stains on the surface of the insulation layer on the outside of the conductor, they will become a hidden danger of inter-turn short circuits after being pressed into the coil by tension. The conductors released from the spool have curl memory. If not treated, they will become loose, bulge or skip turns during the winding process. In addition, static electricity generated by friction during the transportation or winding and unwinding of the conductor will attract dust and oil stains from the air. After being mixed into the winding, they will reduce the interlayer insulation strength and even cause inter-turn breakdown. The existing treatment methods rely on manual post-processing, which cannot deal with and detect problems in a timely manner. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the combined use of a winding mechanism and a guiding tensioning mechanism, can first adapt to EI / EE type iron core frames of different heights and wire feeding rollers of different sizes. Positioning is achieved through a clamping plate at the bottom and elastic clamping is achieved through a top-pressing plate, eliminating the need to replace special chucks. The inclined limiting strips around the bottom plate ensure automatic workpiece centering and coaxiality during clamping. Targeting the multi-specification and small-batch production characteristics of small and medium-sized transformers, it significantly shortens product changeover and debugging time and reduces fixture procurement costs. The symmetrical layout of active rotation on the left and passive wire feeding on the right results in a clear structure and low maintenance costs. The open loading and unloading method allows workers to directly place and quickly clamp the workpiece, lowering the operational threshold and making it suitable for semi-automatic mass production scenarios. The follower frame head, relying on a follower slide rail and multi-section electric telescopic rod, rises and falls synchronously with the winding layers. The conductor is always fed into the winding station at a stable tangential angle, and the wire entry direction always matches the wire laying direction, ensuring uniform pitch and neat alignment between layers. This reduces skipped and overlapping wire problems from a mechanical structure perspective, improving winding size consistency and appearance qualification rate. This invention employs an auxiliary mechanism to perform a four-stage progressive cleaning of the conductor before winding. First, a silicone guide sleeve at the entrance of the guide channel elastically adheres to the outer wall of the conductor, scraping away large-particle dust and debris as the conductor is inserted. This prevents hard particles from entering the internal cleaning chamber and damaging the brush bristles and insulation layer, while also providing initial centering and guidance – this is the first stage of treatment. Next, a circular brush strip thoroughly cleans the outer circumference of the conductor, removing evenly adhered oil and fine dust. Unlike fixed brush strips, this rotating brushing method avoids... The blind spot cleaning area, especially for the residual powder from wire drawing and environmental dust on the surface of the enameled wire, is treated as a secondary process. The use of a ring tube and an air jet head is used to blow away the impurities attached to the cleaning end, preventing the dust from being carried back to the wire surface by the brush strip, thus achieving a tertiary process. Finally, the exterior of the wire is treated by wiping the ring strip with a flexible, oil-absorbing, and wear-resistant material to perform a secondary fine wiping on the surface of the wire after blowing, removing residual thin oil stains and submicron-level dust, ensuring that the wire surface is clean in the final step of the process before entering the subsequent straightening and testing stations.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-2 and Figure 6 The present invention provides a technical solution: an automated winding processing device based on transformer production, including a workbench 1, a work frame 2 installed on the top of the workbench 1, the automated winding processing device also includes a winding mechanism 3, a guiding tensioning mechanism 4 and an auxiliary mechanism 5, and a control panel is installed on one side of the front end of the workbench 1, and a frame plate is installed on the front side of the work frame 2 through a hinge, and the two sides and the rear side of the work frame 2 are all detachable baffles. The winding mechanism 3 is installed on the top of the workbench 1. The inner cavity of the work frame 2 is provided with a guiding tensioning mechanism 4. The guiding tensioning mechanism 4 includes a follower frame head 402. An auxiliary mechanism 5 is installed on the right side of the inner cavity of the follower frame head 402.

[0018] Both sides of the top of the workbench 1 are movably mounted with placement clamps 305. The bottom end of the right placement clamp 305 is connected to the top of the workbench 1 via a bearing. Both sides of the top of the work frame 2 are equipped with telescopic mechanisms, specifically electric push rods 301. The bottom ends of the telescopic mechanisms are each mounted with a pressing top plate 302 via bearings. The top of the left placement clamp 305 is equipped with an iron core frame 303, and the top of the right placement clamp 305 is equipped with a wire feeding roller 308. A wire conductor 309 is wound around the outside of the wire feeding roller 308, and the end of the wire conductor 309 away from the wire feeding roller 308 is connected to the iron core frame. The frame 303 is externally connected and wound. The two extrusion top plates 302 are respectively contacted and extruded to fix the top of the wire feeding roller 308 and the iron core frame 303. A metal plate is installed at the bottom of the bearing at the bottom of the right-side placement clamping plate 305. The metal plate is connected to the rotating end of the bearing. A limit electromagnetic block 307 is installed at the bottom of the metal plate on the right side of the top of the worktable plate 1. An installation notch is opened at the corresponding position of the bearing and the limit electromagnetic block 307 on the right side of the top of the worktable plate 1. When an abnormal situation is detected, the limit electromagnetic block 307 is activated to generate magnetic attraction with the metal plate to achieve positioning and fixing of the wire feeding roller 308. The upper ends of both sides of the inner cavity of the working frame 2 are equipped with stabilizing slide rails 304. Sliding rods are installed on the outside of the stabilizing slide rails 304. The top of the extrusion top plate 302 is equipped with mounting ring rails 310 around the top. The mounting ring rails 310 are equipped with mounting rings 311 on one side of the outside. One end of the sliding rod is connected to one side of the mounting ring 311. Limiting strips are installed around the bottom of the extrusion top plate 302. The limiting strips are inclined on opposite sides. A single-phase motor 306 is installed on the left side of the bottom of the worktable 1. A rotating rod is installed at the output end of the single-phase motor 306. The top of the rotating rod passes through the inside of the worktable 1 and is connected to the bottom of the placement clamp 305 on the left side. The top of the working frame 2 is provided with mounting round openings on both sides. The control panel is electrically connected to the electric push rod 301 and the single-phase motor. The specific implementation method is as follows: During the winding operation, the iron core frame 303 is placed on the top of the left placement clamp 305, and the wire feeding roller 308 with the wire body 309 wound on it is placed on the top of the right placement clamp 305. Then, the electric push rods 301 on both sides are activated to drive the pressing top plate 302 to move downward, so that the bottom end of the pressing top plate 302 contacts and presses the iron core frame 303 and the top end of the wire feeding roller 308 to fix them. During the winding operation, the single-phase motor 306 is activated to drive the left placement clamp 305 to rotate, which in turn drives the iron core frame 303 to rotate and press the wire feeding roller 308 to rotate. 8. The external conductor 309 is wound. When the first layer of winding reaches the top, the next layer of winding is carried out with manual assistance. At the same time, manual inspection is carried out during the manual assistance process. When abnormalities are detected, they are dealt with in time. When the extrusion top plate 302 moves downward, it drives the sliding sleeve rod to slide outside the stabilizing slide rail 304, increasing the flexibility and stability during the movement. When the extrusion top plate 302 rotates, it drives the mounting ring rail 310 to slide inside the mounting ring sleeve 311, increasing the stability and flexibility when the extrusion top plate 302 rotates.

[0019] Please see Figures 2-4 and Figure 7The working frame 2 has a follower slide rail 401 installed on one side of the rear end of the inner cavity. The follower slide rail 401 is slidably installed on the outside of the follower slide sleeve 410. The follower slide sleeve 410 has an auxiliary telescopic mechanism installed on the front side. The auxiliary telescopic mechanism is a multi-section electric telescopic rod 407. The telescopic end of the front side of the auxiliary telescopic mechanism is connected to the rear side of the follower frame head 402. The follower frame head 402 has an upper and lower split structure. The follower frame head 402 has a guide channel 405 in its inner cavity. The guide channel 405 has two detection ends on the left side of its inner cavity. The detection ends are non-contact high voltage electric field electrodes 404. The non-contact high voltage electric field electrodes 404 are electrically connected to the external detection mechanism. The guide channel 405 has a flared structure on the right side of its inner cavity. A rubber rod is installed on the right side of the guide channel 405. The bottom end of the rubber rod is equipped with an electrostatic eliminator rod 406 through a bearing. The electrostatic eliminator rod 406 has a concave structure around its middle part. A support rod 408 is installed on the left rear end of the follower frame head 402. A movable sleeve plate 409 is installed on the left end of the support rod 408. The interface of the movable sleeve plate 409 has an inverted L-shaped structure. The side of the movable sleeve plate 409 away from the support rod 408 has an arc-shaped structure. The movable sleeve plate 409 and the support rod 408 are connected by a rubber block. Pressure sensors are installed on the support rod 408 at the corresponding positions of the rubber block. The side of the movable sleeve plate 409 away from the support rod 408 contacts and rubs against the outside of the wire body 309 during winding. The multi-section electric telescopic rod 407 is electrically connected to the control panel. The specific implementation method is as follows: During the winding process, the conductor 309 first passes through the guide channel 405. When passing through the inner cavity of the guide channel 405, it first contacts the static elimination rod 406. The movement of the conductor 309 drives the static elimination rod 406 to rotate, thereby achieving static elimination treatment with the conductor 309. When encountering a large conductor 309, the elasticity of the rubber block will push the static elimination rod 406 to one side, ensuring that there is no interference with the movement of the conductor 309. At the same time, static elimination treatment can also be performed by the static elimination rod 406. When the conductor 309 moves, the non-contact high-voltage electric field electrode 404 detects the outside of the conductor 309. When there is a pinhole in the paint film at the bottom of the conductor 309 or exposed bare copper, the detection circuit will instantly generate current. The external detection mechanism will immediately alarm and stop or mark the defect location, and activate the limit electromagnetic block 307 to magnetically limit and fix the metal plate, thus fixing the pay-off roller 308. The system has a limit setting. When the conductor 309 moves up and down during layer-by-layer winding, it drives the follower frame head 402 to move. This, in turn, drives the follower slide sleeve 410 to slide outside the follower slide rail 401 via the multi-section electric telescopic rod 407, and drives the moving sleeve plate 409 to move via the support rod 408. The moving sleeve plate 409 presses the winding section to align it. When winding to one layer and then rewinding to the next side, the multi-section electric telescopic rod 407 is activated to drive the follower frame head 402 to move, and also drives the support rod 408 and the moving sleeve plate 409 to move. When the moving sleeve plate 409 contacts and presses against the outside of the conductor 309, the pressure generated during pressing is fed back to the pressure sensor. The pressure threshold generated by the pressure sensor under pressure is set in advance. When an abnormality occurs during the winding process, the pressure threshold is triggered, and the single-phase motor 306 is shut off via the control panel to stop the winding operation. An alarm is also triggered by the external alarm on the control panel to alert the staff for timely handling.

[0020] The inner cavity of the guide channel 405 is provided with a first parallel structure, which includes, but is not limited to, the following specific embodiments: Please see Figures 3-8Method 1: The first parallel structure is configured as a stress treatment mechanism 403. An annular connecting groove is provided on one side of the annular tube 514 within the inner cavity of the guide channel 405. An installation ring frame 4031 is installed at the corresponding position of the annular connecting groove within the inner cavity of the guide channel 405. Several fixed sleeves 4035 are equidistantly installed around the inner cavity of the installation ring frame 4031, and these fixed sleeves 4035 are staggered. The fixed sleeves 4035 are arranged in a ring shape when viewed from the side. A movable push rod 4033 is movably installed within the inner cavity of each fixed sleeve 4035. A guide wheel 4032 is installed at the end of the fixed sleeve 4035 away from the fixed sleeve 4035. A compression spring 4034 is installed at the bottom end of the movable push rod 4033. The end of the fixed sleeve 4035 away from the guide wheel 4032 is unobstructed. The inner wall of the fixed sleeve 4035 is provided with a threaded layer around its perimeter. A compression block 4036 is movably installed in the inner cavity of the fixed sleeve 4035. The compression block 4036 is provided with a thread on its exterior and engages with the threaded layer. The side of the compression block 4036 away from the mounting ring frame 4031 is connected to the compression spring 4034. The specific implementation method is as follows: When the conductor 309 passes through the inside of the mounting ring frame 4031, it will contact the guide wheels 4032 at different positions. Since they are staggered, the guide wheels 4032 will push the movable push rod 4033 to move further into the fixed sleeve 4035, compressing the compression spring 4034. The reaction force generated by the compression spring 4034 is transmitted through the movable push rod 4033 and the guide wheels 4032 to the conductor 309 through multi-directional compression, eliminating the stress of the conductor 309 and performing correction treatment. When adjusting the reaction force, the rotating compression block 4036 moves inside the fixed sleeve 4035, thereby compressing the compression spring 4034 and making the movable push rod 4033 have greater resistance when moving. Through the annular staggered distribution of several fixed sleeves 4035, the conductor 309 continuously contacts the surrounding guide wheels 4032 during its passage, generating alternating micro-bending deformation in multiple radial directions. This breaks the single-direction curling memory brought by the coil. Compared with the planar straightening of the upper and lower rows of rollers, the conductor 309 has better straightness and suppresses serpentine movement. Furthermore, a compression spring 4034 is set at the rear end of the movable top rod 4033, and the guide wheels 4032 are floating structures. When the conductor 309 is too large, it can move back automatically, avoiding rigid compression that flattens the copper conductor and scratches the external insulating varnish. When the winding tension fluctuates instantaneously, it can absorb the impact load and maintain the stability of the conductor body 309 under force. The rotating extrusion block 4036 moves in and out along the thread of the fixed sleeve 4035, pre-compresses the extrusion spring 4034, changes the initial elastic force of the guide wheel 4032 pushing outward, and the production personnel can set the straightening force according to the diameter of the conductor body 309 and the conductor material (soft enameled round wire / thickened insulated wire). The pre-tightening force is reduced for thin wire and increased for thick wire, which is suitable for the production of various specifications of enameled wire for small and medium-sized EI / EE transformers. Meanwhile, the conductor 309 first passes through an auxiliary mechanism to remove surface dust before entering the stress treatment mechanism 403. This prevents hard particles from getting stuck between the guide wheel 4032 and the conductor 309, thus avoiding particles pressing into the insulation layer and forming hidden defects. After straightening, the conductor 309 has a straight posture and minimal sway. When it subsequently passes through the non-contact high-voltage electric field electrode 404, the distance is stable, greatly reducing false alarms caused by impurities and conductor sway.

[0021] Please see Figures 9-10 Method Two: The first parallel structure is configured as an elimination mechanism 6. Guide bodies 601 are movably installed at corresponding positions within the annular docking groove of the guide channel 405. A guide opening 604 with a flared shape is provided on the right side of each guide body 601. A guide channel 602 with a spiral structure is provided inside the guide body 601. The right end of the guide channel 602 is connected to the inner cavity of the guide opening 604. An installation annular groove is provided around the outer periphery of the guide body 601 at corresponding positions within the guide channel 602. An installation strip 605, made of rubber, is installed within the inner cavity of each installation annular groove. Both the installation strip 605 and the installation annular groove have a spiral structure. A flexible smooth layer 603 is installed in the inner cavity of the guide channel 602 and on the side of the mounting strip 605 near the guide channel 602. Mounting recesses 606 are provided around the inner cavity of the guide channel 602 and on one side of the mounting strip 605. An arc-shaped opening is provided in the corresponding position of the flexible smooth layer 603 at each mounting recess 606. A mounting silicone block 607 is installed in the inner cavity of each mounting recess 606. An arc-shaped top block 608 is installed on the side of the mounting silicone block 607 away from the mounting recess 606. The side of the arc-shaped top block 608 away from the mounting silicone block 607 has an arc-shaped structure. Guide balls 609 are movably installed in the inner cavity of each mounting recess 606. The arc-shaped contact area of ​​the arc-shaped top block 608 is polished. The specific implementation method is as follows: When the wire body 309 is wound, one end of the wire body 309 is guided by the guide port 604, so that the wire body 309 passes through the guide channel 602. When the wire body 309 moves inside the spiral structure of the guide channel 602, it will contact the guide ball 609 and drive the guide ball 609 to rotate, reducing the friction during movement and improving the flexibility during movement. When the guide ball 609 is squeezed, it will push the arc-shaped top block 608 to move and squeeze the silicone block 607. The elasticity of the silicone block itself will help to compress the silicone block 607. The nature of the guide ball 609 causes it to exert a reaction force on the conductor 309 to compress it. When encountering conductors 309 of different sizes, the guide ball 609 also compresses the arc-shaped top block 608 and the silicone block 607. It adaptively adjusts according to the size of the conductor 309. When the conductor 309 travels along the spiral trajectory formed by the envelopment of the guide ball 609, it can withstand continuous and alternating reverse bending, eliminating the plastic deformation mechanism of curling stress, and realizing the correction treatment of the conductor 309 before winding. The conductor 309 travels along the spiral guide channel 602, continuously enduring periodic alternating bending. This utilizes plastic deformation to eliminate the coiling memory stored in the conductor 309's winding. The spiral trajectory synchronously corrects the torsional tendency caused by the unwinding of the conductor 309, suppressing its own rotation. The guide ball 609, supported by the silicone block 607, provides elastic support. When the diameter of the conductor 309 changes, the guide ball 609 can autonomously retract, automatically adapting to different specifications of enameled wire within a certain range. This is particularly useful in multi-specification flexible EI / EE transformers for small and medium-sized EI / EE transformers. In production scenarios, product specifications can be changed without disassembling the machine to adjust the mechanism, shortening the changeover and debugging time. The flexible silicone base provides cushioning, preventing stress concentration and avoiding insulation damage and deformation of the conductor 309. After spiral straightening, the conductor 309 is straight and without twisting. When moving later, the conductor 309 will not twist, ensuring that the moving sleeve 409 can evenly squeeze the conductor 309 to achieve wire alignment and improve the neatness of the winding arrangement. At the same time, the conductor 309 has a stable posture, ensuring that the pressure sensor and the non-contact high-voltage electric field electrode 404 can continuously and stably collect signals. Avoiding planar straightening can only eliminate planar curling. The conductor 309 still has helical torsional stress (torsional deformation caused by wire release from the coil). The conductor rotates during winding, causing wire routing disorder. The thin-diameter enameled wire has poor compressive strength. Rigid roller straightening can easily damage the insulation. In addition, avoiding frequent changes in wire diameter requires disassembling and adjusting the roller, resulting in low changeover efficiency. To prevent the conductor 309 from easily rotating and twisting during its movement, the torsional stress is superimposed with the curling stress, resulting in loose winding after winding.

A sealing ring is installed at the connection of the annular air passage 506. A connection port is opened between the top of the inner cavity of the annular air passage 506 and the bottom right side of the inner cavity of the pre-installed groove 502. The bottom of the inner cavity of the mounting slot 502 is provided with a mating interface at the corresponding position of the cleaning ring 508. A servo motor 510 is installed on the right side of the inner cavity of the mounting slot 502. A rotating rod 504 is installed on the output end of the servo motor 510 on the left side. A rotating ring block 518 is installed on the rotating rod 504 at the corresponding position of the mating interface. The rotating ring block 518 has a hollowed-out design at equal intervals around its center. An annular mounting opening is provided around the rotating ring block 518. Several adsorption electromagnetic blocks 519 are installed at equal intervals around the inner cavity of the annular mounting opening. An annular guide layer is installed around the outer perimeter of the annular mounting opening. A turbo fan head 505 is installed on the middle and left side of the rotating rod 504. A rubber strip is installed inside the mating interface. A fiber layer is provided on the outside of the rubber strip. The outer side of the rotating ring block 518 is in contact with the rubber strip. A working filter plate 516 is installed on the left side of the inner cavity of the mounting slot 502. A long brush strip 517 is installed on the left end of the rotating rod 504.

A movable brush strip 507 is installed on the upper right side of the cleaning ring 508, and the right end of the movable brush strip 507 contacts the bottom end of the top filter plate. The inner cavity of the guide channel 405 is provided with a wiping ring 501 on the left side of the annular tube 514. The top end of the wiping ring 501 is connected to the top end of the inner cavity of the guide channel 405. The bottom end of the inner cavity of the guide channel 405 is provided with a mating notch at the corresponding position of the wiping ring 501, and a mating protrusion is installed at the bottom end of the wiping ring 501. A guide sleeve 503 is installed on the right side of the inner cavity of the guide channel 405. The guide sleeve 503 is made of silicone material, and the pressure sensor and servo motor 510 are electrically connected to the external control panel. The implementation method is as follows: When the wire body 309 passes through the guide channel 405 inside the follower frame head 402, the wire body 309 first passes through the middle of the guide sleeve 503. Due to the material of the guide sleeve 503 itself, the guide sleeve 503 is stretched open, and the inner side of the guide sleeve 503 rubs against the outside of the wire body 309. As the wire body 309 continues to move, it passes through the cleaning ring 508 and the wiping ring 501 in sequence. When the wire body 309 moves, the servo motor 510 is activated to drive the rotating rod 504 to rotate, and the adsorption electromagnetic block 519 is activated to generate magnetism. The annular guide layer generates magnetism and forms a magnetic attraction with the annular magnetic ring 509. Through the rotating rod 50... 4. When the rotating ring block 518 rotates, the cleaning ring 508 rotates through magnetic attraction. The cleaning ring 508 drives the annular airbag 511 and the annular brush 512 to rotate. The rotating annular brush 512 cleans the outside of the conductor 309. After cleaning, it passes through the middle of the wiping ring 501 to clean the conductor 309 again. When the cleaning ring 508 rotates, it drives the ball to rotate, reducing the friction when the cleaning ring 508 rotates. When the cleaning ring 508 rotates, it drives the moving brush 507 to move. When the moving brush 507 moves to the position of the filter plate, it will rub against the outside of the filter plate to clean it, so as to prevent impurities attached to the outside of the filter plate from affecting the flow of air. When the rotating rod 504 rotates, it drives the two turbine heads 505 to rotate inside the mounting slot 502, causing the airflow to move to the left. This airflow passes through the working filter plate 516 and is delivered through the conveying port and connecting pipe to the inside of the annular pipe 514. Finally, it is ejected through the jet nozzle 515, causing the ejected airflow to contact the annular brush strip 512. This blows away the dirt adhering to the annular brush strip 512 during cleaning, moving it to the right. Because the guide sleeve 503 forms a relatively sealed state on the right side of the guide channel 405, the cleaned dirt will not escape. When airflow is delivered to the conveying port side, and the mounting slot 502... 2. The right side of the inner cavity is under negative pressure, and the inner cavity of the annular air passage 506 is in a suction state. The cleaned dirt is sucked into the inner cavity of the mounting slot 502 through the suction port. The impurities are blocked by the filter cover and the working filter plate 516 to prevent the dirt from coming into contact with the annular brush strip 512 and re-attaching to the outside of the wire body 309 after subsequent air blowing, which would not achieve the cleaning effect. When encountering wire bodies 309 of different sizes, the annular air bag 511 will be squeezed and deformed. The reaction force of the annular air bag 511 increases the adhesion between the annular brush strip 512 and the outside of the wire body 309. Furthermore, the annular brush bar 512 is installed inside the cleaning ring bar 508 via an annular airbag 511. The elastic deformation of the annular airbag 511 provides the brush bristle adhesion pressure, rather than rigid fixation. When there are slight dimensional fluctuations in the conductor or radial displacement caused by the movement of the moving frame head, the annular airbag 511 can automatically buffer, preventing the brush bristles from scraping hard and causing thinning and scratching of the insulation layer, thus eliminating the hidden insulation damage introduced during the cleaning process. The surface of the cleaned conductor is free of dust and oil. When used in conjunction with the non-contact high-voltage electric field electrode 404 for insulation defect detection, it can significantly reduce false alarms and missed detections caused by surface impurities, improve the accuracy of insulation quality control, and prevent defective conductors from flowing into the winding process. A directional airflow field is formed inside the clean area, so that dirt will not escape into the external workshop environment, nor will it fall onto the iron core frame and winding station to cause winding contamination. This avoids the dust from flowing turbulently in the cavity and re-adhering to the cleaned wires that is easily caused by open air blowing cleaning.
