Description

Technical Field

[0001] This invention relates to the field of insulating tape winding technology for transformer production, and more specifically to an intermittent insulating tape winding machine for transformer production. Background Technology

[0002] In the field of transformer manufacturing, to ensure its electrical insulation performance, it is usually necessary to wrap insulating tape around the surface of components such as the core or coils. Currently, this wrapping operation is generally completed using automated or semi-automated insulating tape wrapping equipment. The existing insulating tape winding process typically follows these steps: First, the operator loads the entire roll of insulating tape onto the unwinding mechanism of the equipment, and clamps and secures its ends using grippers or similar fixing devices. Then, the operator manually pulls the free end of the insulating tape, guiding it through the tensioning device and the lower clamping device. The tensioning device provides appropriate tension to the insulating tape during winding to ensure tight winding; the lower clamping device holds the insulating tape before winding begins or when changing rolls to prevent it from retracting. Once the insulating tape path is set and secured, the winding equipment starts and begins the preset winding operation on the transformer surface. However, the existing technology described above has the following problems in the splicing and replacement of insulating tape rolls. During continuous operation of the winding equipment, when a roll of insulating tape is about to run out, there are currently two main methods of handling this: First, relying on real-time observation by the operator, who manually stops the machine immediately when the tape is visually exhausted and then performs a replacement operation; second, triggering an alarm via a sensor when the insulating tape is completely used up and breaks, followed by replacement by an operator arriving at the scene. Regardless of the method used, the entire production process must be interrupted. Therefore, the existing technology has the following drawbacks: 1. This process is highly dependent on manual intervention, which not only increases the labor intensity and working hours of operators, but also leaves the equipment idle in a non-productive state while waiting for operators to respond and perform operations, further increasing labor and time costs. 2. The inability to automatically identify and seamlessly splice insulating tape rolls restricts the upgrading of production lines towards full automation and intelligence, making it difficult to meet the urgent needs of modern intelligent manufacturing for continuous and efficient production. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intermittent winding machine for insulating tape in transformer manufacturing, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An intermittent insulating tape winding machine for transformer production includes a base plate on which an equipment base is mounted. A winding mechanism, a winding material changing mechanism, and a clamping and rotating mechanism for holding the transformer are mounted on the top surface of the equipment base. The winding mechanism includes a translational slide rail and a translational cylinder. A support plate connected to the output end of the translational cylinder is slidably connected to the translational slide rail. The winding material changing mechanism includes a support column and a height-lifting cylinder connected to the top of the support column. A reciprocating switching component is mounted on the output end of the height-lifting cylinder. The reciprocating switching component includes a square support plate fixedly connected to the output end of the height-lifting cylinder. A main sprocket and multiple driven sprockets are rotatably connected to one side of the support plate. The main sprocket is connected to the driven sprockets via a reciprocating chain. Insert cylinders are equidistantly arranged on the reciprocating chain. A reciprocating motor driving the main sprocket is also connected to the other side of the square support plate.

[0005] Compared with the prior art, the present invention has the following beneficial effects: 1. By integrating the base plate, equipment base, winding mechanism, roll changing mechanism, clamping and rotating mechanism, and auxiliary loading and unloading mechanism, an integrated equipment structure is formed, realizing the automatic replacement of insulating tape, the laying of insulating tape head, the clamping and rotating of transformer, as well as the winding of insulating tape while the transformer is rotating and the automatic loading and unloading of transformer, reducing manual operation; the multi-component integrated design of the winding mechanism provides a stable execution basis for intermittent winding, and improves the continuity and efficiency of the winding operation as a whole; the roll changing mechanism enables the removal of the used insulating tape roll from the surface of the unwinding component and the insertion of unused insulating tape into the surface of the unwinding component, realizing the rapid replacement of the insulating roll; 2. By cooperating with the unwinding component and the tape-laying component, the unopened insulating tape is opened, and the opened end of the insulating tape is pulled to the processing area, avoiding the need for workers to replace or open the insulating tape. At the same time, by cooperating with the tensioning component and the tape-laying component, when the tape-laying component needs to pick up the insulating tape, the tensioning component unfolds to facilitate the tape-laying component to pass through. After the tape-laying component picks up the tape and passes through the tensioning component, the tensioning component retracts and begins to press down and tension the insulating tape. 3. Through the cooperation of the pneumatic cutter, auxiliary bonding component, tape laying component and clamping and straightening component, one side of the insulating tape is easily bonded to the transformer surface, making the bond stronger and facilitating the winding of the transformer. After the specified number of turns are made, it is cut, thus completing the winding of the transformer's insulating tape. Attached Figure Description

[0009] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0010] As an embodiment of the present invention, in order to solve the technical problems in the background art, combined with Figures 1-15As shown, an intermittent winding machine for transformer production includes a base plate 100, a machine base 200 fixedly connected to the top surface of the base plate 100, a winding mechanism 300 mounted on the top surface of the machine base 200, a roll changing mechanism 400 mounted on the top surface of the machine base 200 and on one side of the winding mechanism 300, a clamping and rotating mechanism 500 mounted on the top surface of the base plate 100 and on one side of the winding mechanism 300, a transformer 600 clamped at one end of the clamping and rotating mechanism 500, and an auxiliary loading and unloading mechanism 700 mounted on the top surface of the base plate 100 and in front of the clamping and rotating mechanism 500.

[0011] In one embodiment of the present invention, such as Figure 11 As shown, the winding mechanism 300 includes a translation slide rail 301 and a translation cylinder 302. The translation slide rail 301 and the translation cylinder 302 are fixedly connected to the top surface of the equipment base 200, respectively. A support plate 303 is slidably connected inside the translation slide rail 301. The output end of the translation cylinder 302 is fixedly connected to one side of the support plate 303.

[0012] Furthermore, such as Figure 12 As shown, on the other side of the support plate 303, there are respectively an unwinding component for releasing the insulating tape, a tensioning component for providing tension to the insulating tape, a pneumatic cutter 304 for cutting the insulating tape, an auxiliary adhesive component for pressing the end of the insulating tape onto the surface of the transformer, a tape-grabbing and laying component for grabbing and pulling the end of the insulating tape, and a clamping and straightening component for straightening the insulating tape.

[0013] In practice, the pneumatic cutter is located below the auxiliary bonding component, the tensioning component is located below the pneumatic cutter, the unwinding component is located on one side of the tensioning component, the tape laying component is located below the tensioning component, and the clamping and straightening component is installed on one side of the auxiliary bonding component.

[0014] In one embodiment of the present invention, such as Figure 7 As shown, the roll material changing mechanism 400 includes a support column 401, which is fixedly connected to the top surface of the equipment base 200. A height lifting cylinder 402 is fixedly connected to the top surface of the support column 401. A reciprocating switching component is installed at the output end of the height lifting cylinder 402, and a changing component is installed on one side of the reciprocating switching component.

[0015] Furthermore, the reciprocating switching component includes a square support plate 403, which is fixedly connected to the output end of the height lifting cylinder 402, such as... Figure 8As shown, a main sprocket 404 and a driven sprocket 405 are rotatably connected to one side of the square support plate 403. Preferably, there are three sets of driven sprockets 405. The main sprocket 404 and the three sets of driven sprockets 405 are arranged in an U-shape. The surface of the main sprocket 404 is rotatably connected to the driven sprockets 405 via a reciprocating chain 406. Insert cylinders 407 are fixedly connected at equal intervals to one side of the reciprocating chain 406. A reciprocating motor 408 is fixedly connected to the other side of the square support plate 403. The output shaft end of the reciprocating motor 408 is driven to connect to the main sprocket 404 via a worm gear mechanism. Replacement components are installed on the lower part of one side of the square support plate 403.

[0016] Based on the above technical concept, it can be understood that by integrating the base plate, equipment base, winding mechanism, roll changing mechanism, clamping and rotating mechanism, and auxiliary loading and unloading mechanism, an integrated equipment structure is formed, realizing the replacement of insulating tape, the laying of the end of insulating tape, the clamping and rotating of the transformer, as well as the winding of insulating tape when the transformer is rotating and the automatic loading and unloading of the transformer, reducing manual operation; the multi-component integrated design of the winding mechanism provides a stable execution basis for intermittent winding, and improves the continuity and efficiency of the winding operation as a whole.

[0017] The purpose of the roll replacement mechanism proposed in this invention is to remove the used insulating tape roll from the surface of the unwinding component and insert the unused insulating tape into the surface of the unwinding component, thereby achieving rapid replacement of the insulating tape roll. Furthermore, it is proposed that by coordinating the unwinding component and the tape laying component, the unopened insulating tape can be opened, and the opened end of the insulating tape can be pulled to the processing area, thus avoiding the need for workers to replace and open the insulating tape.

[0018] Furthermore, it is proposed that through the cooperation of the tensioning component and the tape-laying component, when the tape-laying component needs to pick up the insulating tape, the tensioning component unfolds to facilitate the tape-laying component's passage. After the tape-laying component picks up the tape and passes through the tensioning component, the tensioning component retracts and begins to press down and tension the insulating tape. It is also proposed that through the cooperation of the pneumatic cutter, auxiliary adhesion component, tape-laying component, and clamping and straightening component, one side of the insulating tape can be easily adhered to the transformer surface, making the adhesion more secure and facilitating the winding of the transformer. After the specified number of turns is reached, it is cut, thus completing the winding of the transformer's insulating tape.

[0019] Furthermore, it is proposed that by changing the internal shape of the tape-picking and laying component, it can adapt to two situations. First, when picking up the end of the insulating tape, the end of the insulating tape can be separated and clamped and pulled for laying. Second, when the insulating tape is wrapped and stuck together, or when the insulating tape is used to the end and the insulating tape separates from the insulating cylinder, the tape-picking and laying component will clamp the insulating tape to prevent it from loosening during winding or the insulating tape from being untensioned.

[0020] In one embodiment of the present invention, such as Figures 9-10 As shown, the replacement component includes a guide groove 409 and a separation cylinder 410. A guide groove 409 is symmetrically arranged on one side of a square support plate 403, and a separation cylinder 410 is fixedly connected to the other side of the square support plate 403. An opposing slide rail 411 is fixedly connected to the output end of the separation cylinder 410. A primary clamping arm 412 is slidably connected to both ends of the surface of the opposing slide rail 411. A secondary clamping arm 413 is slidably connected to the surface of the primary clamping arm 412. A forward-pushing cylinder 414 is fixedly connected to one end of the primary clamping arm 412. The secondary clamping arm 413 is fixedly connected to the output end of the forward-pushing cylinder 414. The primary clamping arm 412 slides along the guide groove 409 to realize the gripping, transfer and installation of the insulating tape roll to the working position.

[0021] Understandably, the guide groove ensures sliding stability, the separation cylinder adjusts the overall front-to-back position, and the opposing slide rails enable the two sets of clamping rods to retract in opposite directions. The two-section clamping rods, in conjunction with the forward-pushing cylinder, flexibly adjust the clamping distance. This structure can precisely clamp insulating tape rolls at different positions, enabling automated and precise operations for removing old materials, switching to new materials, and loading materials, avoiding positioning deviations during the replacement process.

[0022] In one embodiment of the present invention, such as Figures 11-12 As shown, the unwinding component includes an unwinding driver 305 and an unwinding reel 306 driven by it. The unwinding driver 305 is fixedly connected to one side of the support plate 303. The output shaft of the unwinding driver 305 is driven to connect to the unwinding reel 306 via a worm gear mechanism. The unwinding reel 306 is rotatably connected inside the support plate 303. A sleeve clamp 307 is installed in the middle of the unwinding reel 306. It should be noted that the sleeve clamp can internally hold the insulating tape drum. The unwinding driver drives the unwinding reel to rotate through a worm gear transmission, resulting in smooth transmission and controllable speed. The purpose is to ensure that the insulating tape release process is uniform and stable, avoiding slack or pulling damage, and providing a stable material supply for subsequent tensioning and winding. When the unwinding component cooperates with the tape picking and laying component, it realizes the picking and laying of the insulating tape head.

[0023] In one embodiment of the present invention, such as Figure 14As shown, the tensioning component includes a vertical slide rail 308, a side support rod 309, and a screw slide rail 310. The vertical slide rail 308, the side support rod 309, and the screw slide rail 310 are fixedly connected to one side of the support plate 303. There are two sets of vertical slide rails 308. A lower tensioning roller 311 is rotatably connected to one side of the side support rod 309. A vertical slider 312 is slidably connected inside the vertical slide rail 308. An upper tensioning roller 313 is rotatably connected to one side of the vertical slider 312. A lifting rod 314 is slidably connected to the surface of the screw slide rail 310. One side of the lifting rod 314 is in contact with the bottom surface of the vertical slider 312.

[0024] Understandably, the screw-driven lifting rod controls the vertical slider's rise and fall, thereby adjusting the distance between the upper and lower tension rollers. When the upper tension roller is far from the lower tension roller, it facilitates the tape-laying component passing through the middle. When the upper and lower tension rollers are close together, the upper tension roller, relying on gravity, works in conjunction with the lower tension roller to form a tension adjustment mechanism. The tension can be flexibly adjusted according to the insulation tape material and winding requirements, ensuring uniform tension of the insulation tape during winding, thus improving winding density and consistency.

[0025] In one embodiment of the present invention, such as Figure 12 , Figure 15 As shown, the tape laying component includes a laying track 315, which is fixedly connected to one side of the support plate 303. A laying slider 316 is slidably connected to one side of the laying track 315. A lifting cylinder 317 is fixedly connected to the top surface of the laying slider 316. An angle adjustment plate 318 is fixedly connected to the output end of the lifting cylinder 317. An angle driver 319 is fixedly connected to one side of the angle adjustment plate 318. An angle shaft 320 is driven to the output shaft end of the angle driver 319 through a worm gear mechanism. A conversion component is installed at one end of the angle shaft 320.

[0026] Understandably, the height of the changing component is adjusted by a lifting cylinder, the angle actuator controls the steering of the changing component, and the laid track drives the entire structure to move back and forth. This structure can precisely align with the unwinding component to grasp the rubber head, and through multi-dimensional adjustments, achieve directional traction of the insulating tape, quickly guiding the insulating tape to the tensioning component and the clamping and straightening component, connecting to the subsequent winding process.

[0027] In one embodiment of the present invention, such as Figure 15 As shown, the transformation component includes a transformation bracket 321. One end of the angle shaft 320 is fixedly connected to the transformation bracket 321. Two ends of one side of the transformation bracket 321 are respectively fixedly connected to deflection drivers 322. The output shaft end of the deflection driver 322 independently drives a clamping arm 323 to deflect through a worm gear mechanism. One end of the clamping arm 323 is fixedly connected to a guide roller 324.

[0028] Understandably, when the deflection driver drives the two sets of clamping arms to form an upward-opening V-shaped clamping structure, it can precisely clamp the adhesive head. This clamping also facilitates the subsequent insertion of the clamping and straightening components between the two sets of clamping arms to clamp the end of the insulating tape. When the two sets of clamping arms form a downward-opening V-shaped clamping structure, the two sets of guide rollers will adhere to the surface of the insulating tape and create compression, preventing the tape from losing traction when the tail of the insulating tape detaches from the tape roll, thus avoiding loosening of the tape during winding. This structure ensures stable gripping of the adhesive head and keeps the insulating tape straight during traction, guaranteeing precise adhesion at the beginning of winding.

[0029] In one embodiment of the present invention, such as Figure 7 , Figure 13 As shown, the auxiliary bonding component includes a propulsion cylinder 325, which is fixedly connected to one side of the support plate 303. A buffer damper 326 is fixedly connected to the output of the propulsion cylinder 325. A U-shaped frame 327 is fixedly connected to one end of the buffer damper 326. A switching motor 328 is fixedly connected to one side of the U-shaped frame 327. A semi-circular pressure roller 329 is driven to the output shaft end of the switching motor 328 through a worm gear mechanism. A brush 330 is fixedly connected to one side of the semi-circular pressure roller 329. Driven by the switching motor 328, either the semi-circular pressure roller 329 or the brush 330 can be selectively applied to the surface of the insulating tape to achieve a pressing or initial bonding effect.

[0030] Understandably, the propulsion cylinder drives the brush to contact the surface of the insulating tape, enhancing the initial adhesion and preventing the insulating tape from detaching from the transformer due to traction during subsequent winding. The buffer damper prevents excessive contact force from damaging the insulating tape and ensures that the semi-circular pressure roller remains in contact with the transformer while it rotates. The switching motor controls the switching between the semi-circular pressure roller and the brush. This structure ensures a tight fit of the insulating tape from initial adhesion to winding, preventing loosening or detachment and improving winding quality.

[0031] In one embodiment of the present invention, such as Figure 7 , Figure 12 As shown, the clamping and straightening component includes a material-picking track 331, which is fixedly connected to one side of the support plate 303. A material-picking plate 332 is slidably connected inside the material-picking track 331, and a material-picking claw 333 is installed on the bottom surface of the material-picking plate 332. In practice, the material-picking claw clamps one end of the insulating tape, and the material-picking plate moves up and down along the material-picking track to pull it, ensuring that the insulating tape is straightened without bending. After winding, the remaining rubber head can be quickly clamped and pulled back, saving preparation time for the next transformer winding and improving the efficiency of intermittent operation.

[0032] In one embodiment of the present invention, such as Figure 1 , Figure 3As shown, the clamping and rotating mechanism 500 includes a vertical support column 501. The vertical support column 501 is fixedly connected to the top surface of the base plate 100. The top surface of the vertical support column 501 is fixedly connected to a forward slide rail 502. A forward slide plate 503 is slidably connected inside the forward slide rail 502. A motor mounting plate 504 and a forward support 505 are fixedly connected to one end of the top surface of the forward slide plate 503. An inner gripper 506 is rotatably connected inside the forward support 505. A winding motor 507 is fixedly connected to one side of the motor mounting plate 504. The output shaft end of the winding motor 507 is rotatably connected to the inner gripper 506 through a gear set.

[0033] Understandably, the inner grippers precisely hold the inside of the transformer, and the forward slide rail adjusts the gripping position to facilitate the inner grippers' cooperation with the auxiliary loading and unloading mechanism for loading and unloading the transformer. Meanwhile, the winding motor drives the transformer to rotate smoothly in both directions via a gear set, ensuring the adhesion and tightness of the insulation tape to the transformer during winding, while also facilitating the switching of the transformer in coordination with the loading and unloading components.

[0034] In one embodiment of the present invention, such as Figure 1 , Figures 4-6 As shown, the auxiliary loading and unloading mechanism 700 includes a loading conveyor belt 701, a unloading conveyor belt 702, and a lifting cylinder 703. The loading conveyor belt 701, the unloading conveyor belt 702, and the lifting cylinder 703 are fixedly connected to the top surface of the base plate 100. An avoidance damping rod 704 is fixedly connected to the bottom surface of the output end of the loading conveyor belt 701. A barrier plate 705 is fixedly connected to one end of the avoidance damping rod 704. A long plate 706 is fixedly connected to the output end of the lifting cylinder 703. An L-shaped plate 707 is fixedly connected to the upper part of one side of the long plate 706. A bending connecting rod 708 is fixedly connected to one side of the L-shaped plate 707. A discharge cylinder 709 is fixedly connected inside the bending connecting rod 708. A unloading plate 710 is fixedly connected to the output end of the discharge cylinder 709. A receiving seat 711 is fixedly connected to the lower part of one side of the long plate 706. A receiving groove 712 is provided on the top surface of the receiving seat 711.

[0035] It should be noted that the feeding conveyor belt is used to continuously transport the transformers to be processed. The receiving seat 711 and the baffle plate 705 control the conveying rhythm. Simultaneously, when the baffle plate does not require feeding, it intercepts the transformer 600 to prevent it from falling off the feeding conveyor belt. The lifting cylinder is used to adjust the height, working with the inner gripper 506 to complete material handling and unloading. The unloading cylinder moves the finished product to the unloading conveyor belt, achieving automated loading and unloading. This structure reduces manual intervention, prevents damage to the transformer 600, achieves continuous connection between belt winding and loading / unloading, and improves overall production efficiency.

[0036] The working principle of this invention is as follows: S1. Steps for applying insulating tape: S1-1. Replacement of insulating tape rolls: The worker removes the used insulating tape rolls from the surface of the insert roll 407 and inserts the unopened insulating tape into the insert roll 407.

[0037] S1-2. Unwinding component loading (including material handling, switching, and feeding): If there is residual used insulating tape on the surface of the unwinding component, it must be removed before inserting the unopened insulating tape. Material handling operation: The height lifting cylinder 402 drives the reciprocating switching component and the replacement component to move downwards, and stops working after moving to the side of the unwinding component; the separation cylinder 410 is started, and when it retracts, it drives the opposing slide rail 411, the first-stage clamping arm 412, the front telescopic pneumatic rod 414 and the second-stage clamping arm 413 to move forward. The first-stage clamping arm 412 slides along the guide rail 409, so that the end of the second-stage clamping arm 413 moves to the end of the insulating tape tube to be clamped; At this time, the front telescopic pneumatic rod 414 works, driving the secondary clamping arm 413 to slide along the primary clamping arm 412 to the surface of the insulating tape tube. The opposing slide rail 411 drives the two sets of clamping rods to retract in opposite directions, completing the clamping of the insulating tape tube.

[0038] The cylinder 410 and the front telescopic pneumatic rod 414 are reset, and the old insulating tape tube on the surface of the sleeve clamp 307 is removed and placed on the empty cartridge 407. Loading operation: Start the reciprocating motor 408, which drives the reciprocating chain 406 to rotate with the cooperation of three sets of driven sprockets 405, thereby driving the four sets of insert cylinders 407 to switch positions, conveying the unopened insulating tape to the replacement part, and at the same time conveying the old insulating tape cylinder out; after the unopened insulating tape is in place, the opposing slide rail 411 drives the two sets of clamping rods to retract, the separation cylinder 410 is activated, and one end of the secondary clamping arm 413 abuts against the end of the insulating tape and pushes the insulating tape, so that it slides along the insert cylinder 407 to the surface of the sleeve clamp 307 and is clamped, completing the loading; it should be noted that if there is no unused insulating tape cylinder on the surface of the sleeve clamp 307, the material picking step can be omitted and loading can be carried out directly.

[0039] S1-3. Preparation for tape pickup (adjustment of tensioning components + pickup of rubber head) Tensioning component adjustment: The screw slide rail 310 starts, driving the lifting rod 314 to move upward. When one side of the lifting rod 314 contacts the vertical slider 312, it continues to move upward, driving the vertical slider 312 and the upper tensioning roller 313 to rise synchronously. When the upper tensioning roller 313 moves to the highest position, the lifting rod 314 stops moving. Insulating tape end pickup: The lifting cylinder 317 is activated, driving the angle adjusting plate 318, the changing bracket 321, the guide roller 324, and the clamping arm 323 to move down to a suitable position and then stop; the laying track 315 drives the angle adjusting plate 318, the angle driver 319, the deflection driver 322, and the clamping arm 323 through the tensioning component and move to the unwinding component and stop; the angle driver 319 drives the angle shaft 320 to rotate, driving the changing bracket 321 and the clamping arm 323 to rotate to a suitable angle and then stop. At this time, the end of one set of clamping arms 323 contacts the surface of the insulating tape; the unwinding driver 305 is activated, driving the unwinding disc 306 and the sleeve gripper 307 to rotate, driving the insulating tape to rotate synchronously, and scraping off the tape end under the action of the clamping arm 323; another set of clamping arms 323 rotates, and the two sets of clamping arms form a V-shaped structure to clamp the scraped-off insulating tape end. Tape traction and tension reset: The laying track 315 is restarted, driving the clamping arm 323 to move, pulling the insulating tape through the upper tensioning roller 313 and the lower tensioning roller 311 in sequence, and then pulling it to the bottom of the clamping and straightening component; the angle of the two sets of clamping arms 323 is adjusted by the deflection driver 322, turning the V-shaped opening that was originally pointing to the right to pointing upward; the lifting rod 314 moves down along the screw slide rail 310, and the upper tensioning roller 313 slides down along the vertical slide rail 308 under the action of gravity and presses on the surface of the insulating tape, which, together with the lower tensioning roller 311, achieves the tensioning of the insulating tape.

[0040] S2, Steps for wrapping insulating tape S2-1. Tape Traction and Positioning: The picking plate 332 moves downward along the picking track 331, and the end of the picking claw 333 inserts between the two sets of clamping arms 323 to clamp one end of the insulating tape. After clamping, the two sets of clamping arms 323 deflect under the drive of the deflection driver 322, turning the originally upward V-shaped opening downward. The two sets of guide rollers 324 lightly clamp the surface of the insulating tape to ensure that it remains straight during stretching. After the picking claw 333 clamps one end of the tape, the picking plate 332 moves upward along the picking track 331, pulling the insulating tape... Pulled out from between two sets of guide rollers 324; the translation cylinder 302 is activated, driving the support plate 303 to move, adhering the insulating tape between the picking claw 333 and the guide roller 324 to the surface of the transformer; the propulsion cylinder 325 is activated, driving the semi-circular pressure roller 329 and the brush 330 to move forward, the brush 330 presses against the surface of the insulating tape to make it fit more tightly with the transformer, after multiple contact, the switching motor 328 drives the semi-circular pressure roller 329 to rotate and collect the brush 330, and the surface of the semi-circular pressure roller 329 contacts the transformer 600.

[0041] S2-2, Winding and Cutting: The winding motor 507 first drives the inner gripper 506 to rotate, so that the end of the insulating tape adheres to the transformer 600. Then, it drives the inner gripper 506 to rotate forward to start winding. During the winding process, the semi-circular pressure roller 329 is always in contact with the transformer surface to prevent the winding from loosening. When the winding is about to be completed, the pneumatic cutter 304 starts and cuts the insulating tape from above the guide roller 324. The inner gripper 506 continues to rotate to finish winding the remaining insulating tape. After the winding is completed, the material picking gripper 333 moves down again to pick up and pull the insulating tape in the area held by the guide roller 324, preparing for the next transformer winding.

[0042] S3, Transformer loading and unloading procedures S3-1, Material queuing: Transformers without insulating tape are conveyed by the material conveyor belt 701. When one transformer is conveyed to the receiving trough 712, the remaining transformers queue up in sequence.

[0043] S3-2, Transformer replacement (finished product unloading + raw material loading): The forward slide rail 502 drives the forward slide plate 503, forward bracket 505, inner gripper 506 and winding motor 507 to move forward, moving the processed transformer to the front end. The lifting cylinder 703 is activated, causing the long plate 706, L-shaped plate 707, receiving seat 711, and unloading cylinder 709 to move upwards as a whole. The receiving seat 711 drives the unprocessed transformer to rise synchronously, and at the same time, it no longer opposes the blocking plate 705. The blocking plate 705 moves upwards under the action of the avoidance damping rod 704, blocking the subsequent loading of transformers. The L-shaped plate 707 and the unloading plate 710 move to below the inner clamp 506. The L-shaped plate 707 lifts the transformer 600, while the unloading plate 710 supports the transformer. One side of the transformer 600 is limited to prevent the finished transformer from falling off the L-shaped plate 707 when the inner clamp 506 releases it. When the inner clamp 506 is released, the forward slide rail 502 retracts and the finished transformer falls onto the L-shaped plate 707. At the same time, the lifting cylinder 703 rises again, raising the receiving seat 711 to a position flush with the inner clamp 506. The inner clamp 506 moves forward, inserts into the middle of the unprocessed transformer, and clamps it. Then it retracts and resets, ready for the winding operation. Material unloading operation: During the transformer winding process, the lifting cylinder 703 is reset, the receiving seat 711 presses down on the blocking plate 705 and returns to the side of the feeding conveyor belt 701 to prepare for material removal; the L-shaped plate 707 moves to the side of the unloading conveyor belt 702, the unloading cylinder 709 is started, and the unloading plate 710 pushes the finished transformer to the unloading conveyor belt 702 to complete the unloading.
