Description

Technical Field

[0001] This application relates to the field of transformer manufacturing, and in particular to a transformer tape wrapping device. Background Technology

[0002] A transformer tape wrapping device is a key piece of equipment used for automated winding of insulating tape in the transformer production process. This type of machine typically includes a workbench and core components such as a tape storage rack, a rotary table, a rotating motor, a cutter, a reciprocating device, and a control panel. The tape storage rack is used to hold tape rolls. Multiple workstations are symmetrically arranged on the rotary table. Each workstation is equipped with a rotating motor and a fixed insertion frame. The reciprocating device drives the cutter to perform the tape cutting action. The control panel is used to set parameters and coordinate the operation of various components to realize the automatic feeding, winding, and cutting of the tape.

[0003] A typical workflow of a transformer tape wrapping device is as follows: The operator places the transformer in a fixed frame, manually attaches the starting section of tape to the surface of the transformer, then starts the equipment, the rotary table rotates, sending the workpiece to the winding station, the self-rotating motor drives the transformer to rotate, so that the tape is wrapped around its outer perimeter layer by layer. After the wrapping is completed, the rotary table switches stations, the reciprocating device drives the cutter to cut the tape, the operator removes the wrapped workpiece and reloads the material.

[0004] The existing method of fixing the transformer during rotation and winding involves inserting it into the plug-in frame of the self-rotating motor. Due to the lack of radial and axial constraints, the free end is easily affected by factors such as rotational centrifugal force and tape tension, which can cause it to sway or move axially. This instability can lead to deviations in the tape winding position, resulting in quality defects such as interlayer wrinkles, uneven overlap, or uneven gaps in the tape. This not only affects the insulation performance and appearance consistency of the product, but also requires manual rework, reducing production efficiency and product qualification rate. Summary of the Invention

[0005] The purpose of this application is to address the problem that the existing fixing method mentioned in the background art involves inserting the transformer into the plug-in frame of the self-rotating motor. The free end of the transformer, lacking radial and axial constraints, is easily affected by factors such as centrifugal force and tape tension, causing it to sway or move axially. This instability leads to deviations in the tape winding position, resulting in quality defects such as tape layer wrinkles, uneven overlap, or uneven gaps. This not only affects the insulation performance and appearance consistency of the product but also requires manual rework, reducing production efficiency and product qualification rate. This application provides a transformer tape wrapping device.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A transformer tape wrapping device includes a workbench with a tape storage rack for supplying tape. Tape rolls are mounted on the tape storage rack. A turntable is mounted on the workbench with two symmetrically arranged workstations. Each workstation has a fixed self-rotating motor, the output end of which is connected to a clamping and fixing mechanism for gripping and driving the transformer to rotate. An auxiliary positioning mechanism is provided on the workbench corresponding to the winding workstation on the turntable, used to press against the free end of the transformer during winding to limit axial movement and radial sway of the transformer during rotation. A reciprocating device is also mounted on the workbench, with a cutter fixed to its reciprocating end for cutting the tape after winding. A control panel is mounted on the workbench for controlling the turntable's workstation switching, the start / stop and speed of the self-rotating motor, the cutting action of the reciprocating device, and the positioning action of the auxiliary positioning mechanism.

[0007] By adopting the above technical solution, the self-rotating motor holding the transformer is rotated to the working position, facing the auxiliary positioning mechanism. Subsequently, the auxiliary positioning mechanism is activated, and its positioning end stably abuts against the free end of the transformer. The self-rotating motor starts, which can effectively prevent the shaking and axial movement of the transformer when it rotates at high speed. This fundamentally avoids the problems of uneven tape winding, wrinkles, or gaps caused by transformer displacement.

[0008] Furthermore, the auxiliary positioning mechanism includes a support base fixed on the worktable, a positioning rod provided on the support base, the positioning rod being U-shaped, a positioning ball sliding and rotating at one end of the positioning rod, an abutting support assembly provided between the positioning ball and the positioning rod, and an adjustment assembly provided between the positioning rod and the support base.

[0009] By adopting the above technical solution, the transformer squeezes the positioning ball, which is pressed tightly against the transformer end face under the thrust of the support component. Since the positioning ball can rotate, it forms rolling friction with the rotating transformer surface, thereby providing good stable support for the transformer, reducing the possibility of shaking or deviation when the transformer rotates, reducing wear and heat accumulation between the transformer and the rotating transformer, protecting the integrity of the transformer surface, and at the same time, the adjustment component can drive the positioning rod to move laterally, thus adapting to multi-variety production.

[0010] Furthermore, the abutment support assembly includes an adjusting bolt threaded onto the positioning rod, an adjusting hole extending through the positioning rod, and an abutment spring disposed within the adjusting hole on the positioning rod, with both ends of the abutment spring abutting against the adjusting bolt and the positioning ball, respectively.

[0011] By adopting the above technical solution, the operator can use tools to rotate the adjusting bolt to change the compression of the anti-spring according to the weight of the transformer and the expected winding speed, thereby achieving the best support effect. At the same time, the introduction of the anti-spring makes the support elastic rather than rigid, which can absorb the small vibrations generated when the transformer rotates, further stabilize the winding process, and improve the winding quality.

[0012] Furthermore, the adjustment assembly includes a sliding seat slidably connected to a support base, an adjustment threaded rod rotatably connected to the support base, the adjustment threaded rod passing through the sliding seat and threadedly connected to the sliding seat, and an adjustment motor fixedly mounted on the support base, the output end of the adjustment motor being fixedly connected to the adjustment threaded rod.

[0013] By adopting the above technical solution, the motor can be adjusted to rotate forward or backward, driving the adjusting screw rod to rotate, thereby causing the sliding seat and the entire positioning mechanism to move forward or backward precisely along the guide rail. This enables the automated and precise control of the positioning ball, with an accuracy far exceeding that of manual adjustment. Furthermore, it can be linked with the equipment control system to achieve rapid recall of different product parameters.

[0014] Furthermore, the clamping and fixing mechanism includes a support plate fixed to the output end of the self-rotating motor. Two symmetrical clamping plates are provided on the side of the support plate away from the self-rotating motor. A connecting rod is provided on each of the two clamping plates. A movable block is provided on the support plate. One end of the connecting rod is rotatably connected to the movable block. A pushing rod is fixed on the movable block. An abutting rod is fixed on the pushing rod. A sliding support assembly is provided between the movable block and the support plate. A spacing assembly is provided between the clamping plate and the support plate.

[0015] By adopting the above technical solution, the transformer pushes the contact plate, the contact rod drives the push rod, and the push rod drives the moving block. The moving block moves on the support plate under the support of the sliding support assembly. The moving block pulls the connecting rod, which drives the two spacing components. The two spacing components drive the clamping plate to clamp the transformer, thereby further fixing the transformer and reducing the possibility of movement or displacement when the transformer rotates. It also has a spacing adjustment function. One set of clamps can adapt to various transformers within a certain size range, and has strong versatility.

[0016] Furthermore, the sliding support assembly includes two connecting blocks 1 symmetrically fixed on the support plate, and a support slide rod is fixed between the two connecting blocks 1. The support slide rod passes through the moving block and is slidably connected to the moving block. A return spring is sleeved on the support slide rod, and the two ends of the return spring abut against the connecting block 1 and the moving block respectively. A fixing member is provided on the moving block.

[0017] By adopting the above technical solution, the external force pushes the moving block to compress the return spring and slide along the support slide rod to achieve clamping. When the clamping is in place, the fixing part moves to lock the moving block in that position, thereby ensuring the smoothness and coaxiality of the clamping action. The return spring ensures that the clamp can open automatically and quickly when the external force is lost, improving safety and work efficiency.

[0018] Furthermore, the fixing component includes two connecting blocks two symmetrically fixed on the support plate, a fixing rod fixed between the two connecting blocks two, a plurality of evenly distributed fixing grooves one on the fixing rod, a plug-in rod slidably connected to the moving block, the plug-in rod having fixing grooves two corresponding to the fixing grooves, the fixing grooves one and two facing opposite directions, a limiting spring sleeved on the plug-in rod, the two ends of the limiting spring being fixedly connected to the moving block and the plug-in rod.

[0019] By adopting the above technical solution, the ratchet-type plug rod and fixing rod allow the moving block to move forward in one direction and lock in multiple positions, thereby providing stable locking for the transformer, with strong vibration resistance and high reliability. The uniform distribution of the teeth means that the moving block can be locked in multiple stroke positions, increasing the flexibility of clamping range adjustment.

[0020] Furthermore, the spacing assembly includes an adjusting plate disposed on the clamping plate, the end of the connecting rod away from the moving block is rotatably connected to the adjusting plate, a spacing bolt is threadedly connected to the adjusting plate, the spacing bolt passes through the adjusting plate and is rotatably connected to the clamping plate, a limit rod is fixed on the clamping plate, the limit rod passes through the adjusting plate and is slidably connected to the adjusting plate.

[0021] By adopting the above technical solution, the clamping plate is forced to move forward or backward in a straight line relative to the adjusting plate by rotating the clamping bolt with a tool, since the limit rod restricts the rotation of the clamping plate. This allows for precise control of the center symmetry and opening size of the clamp, adapting to asymmetrical transformers or achieving precise centering.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, during transformer replacement or initial setup, the operator drives the entire positioning rod and its front-end positioning ball to move horizontally via the adjustment component, roughly aligning it with the transformer's central axis. When the equipment is running, after the clamping and fixing mechanism drives the transformer to rotate and approach, the transformer squeezes the positioning ball. Under the thrust of the resistance support component, the positioning ball presses tightly against the transformer end face. Because the positioning ball is rotatable, it forms rolling friction with the rotating transformer surface, providing stable axial and radial limits while avoiding scratches on the transformer surface. This achieves good stable support for the transformer, reducing the possibility of swaying or shifting during transformer rotation, which could cause wrinkles and shifts in the conveyor belt. The rotatable positioning ball design transforms sliding friction into rolling friction, reducing wear and heat accumulation between the rotating transformer and the transformer, protecting the integrity of the transformer surface. At the same time, the adjustment component can drive the positioning rod to move laterally, thereby adapting to multi-variety production and improving the production qualification rate.

[0023] 2. In this application, by pre-adjusting the initial distance between the two clamping plates according to the thickness of the transformer and the spacing components, when the transformer is placed between the two clamping plates, the transformer pushes the contact plate, the contact rod drives the push rod, and the push rod drives the moving block. The moving block moves on the support plate under the support of the sliding support component. The moving block pulls the connecting rod, which drives the two spacing components. The two spacing components drive the clamping plates to clamp the transformer. The self-rotating motor drives the entire clamping and fixing mechanism and the clamped transformer to rotate, which achieves further fixing of the transformer and reduces the possibility of movement or displacement when the transformer rotates. At the same time, it has the function of spacing adjustment. One set of clamps can adapt to various transformers within a certain size range, which is highly versatile.

[0024] 3. In this application, when the moving block is pushed toward the fixed rod, the plug rod is in a retracted state under the action of the limit spring. After moving to the desired position, the plug rod can be pushed manually or by a small cylinder to make the second fixed tooth groove on it mesh with the first fixed tooth groove on the fixed rod. Since the teeth are opposite, the moving block cannot move in the opposite direction and is reliably locked. When it is necessary to release, the plug rod is pulled outward again to overcome the force of the limit spring and make the teeth groove separate. The moving block then retracts under the action of the return spring. This achieves the purpose of providing stable locking for the transformer, strong anti-vibration ability, and high reliability. The uniform distribution of the teeth grooves means that the moving block can be locked at multiple stroke positions, increasing the flexibility of clamping range adjustment.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses a transformer tape wrapping device.

[0029] Reference Figure 1 , Figure 2 and Figure 3A transformer tape wrapping device includes a tape storage rack 2 for supplying tape on a workbench 1, on which tape rolls 10 are mounted. A turntable 3 is mounted on the workbench 1, with two symmetrical workstations on the turntable 3. Each workstation is equipped with a self-rotating motor 4, the output end of which is connected to a clamping and fixing mechanism 7 for clamping and driving the transformer to rotate. An auxiliary positioning mechanism 6 is provided on the workbench 1 corresponding to the winding workstation of the turntable 3, which is used to press the free end of the transformer during the winding process to limit the axial movement and radial sway of the transformer during rotation. A reciprocating device 8 is also mounted on the workbench 1, with a cutter 5 fixed to the reciprocating end of the reciprocating device 8, which is used to cut the tape after winding. A control panel 9 is mounted on the workbench 1, which is used to control the workstation switching of the turntable 3, the start / stop and speed of the self-rotating motor 4, the cutting action of the reciprocating device 8, and the positioning action of the auxiliary positioning mechanism 6.

[0030] When using this transformer tape wrapping device, the operator places the transformer into one of the clamping and fixing mechanisms 7 and clamps it. The tape is then pulled from the tape roll 10 and manually applied to the transformer's starting position. The device is started via the control panel 9. The turntable 3 rotates first, rotating the self-rotating motor 4 holding the transformer to its working position, directly facing the auxiliary positioning mechanism 6. Subsequently, the auxiliary positioning mechanism 6 activates, its positioning end stably contacting the free end of the transformer. The self-rotating motor 4 starts, driving the transformer to rotate at a uniform speed, wrapping the tape around the transformer. Simultaneously, the operator places another transformer into the clamping and fixing mechanism 7 at the front end of another self-rotating motor 4. After the preset number of turns is reached, the self-rotating motor 4 stops. After the tape wrapping is complete, the turntable 3 rotates again to complete the tape wrapping process. The transformer and the transformer without tape are swapped. At the same time, the auxiliary positioning mechanism 6 continues to assist in positioning the transformer. Driven by the transformer with tape, the tape comes into contact with the transformer without tape. The reciprocating device 8 drives the cutter 5 forward to cut the tape. Then, the self-rotating motor 4 drives the corresponding transformer to start wrapping the tape. The operator removes the transformer that has been wrapped and replaces it with a new transformer to prepare for the next operation. By setting the auxiliary positioning mechanism 6 at the station where the transformer rotates and wraps the tape, the auxiliary positioning mechanism 6 provides stable support for the free end of the transformer, which can effectively prevent the shaking and axial movement of the transformer when it rotates at high speed. This fundamentally avoids the problem of uneven tape wrapping, wrinkles or gaps caused by transformer displacement.

[0031] Reference Figure 2 , Figure 3 and Figure 4The auxiliary positioning mechanism 6 includes a support base 61 fixed on the worktable 1, a positioning rod 62 provided on the support base 61, the positioning rod 62 is U-shaped, a positioning ball 63 slides and rotates at one end of the positioning rod 62, an abutting support component 64 is provided between the positioning ball 63 and the positioning rod 62, and an adjustment component 65 is provided between the positioning rod 62 and the support base 61.

[0032] During transformer replacement or initial setup, the operator uses the adjusting component 65 to drive the entire positioning rod 62 and its front-end positioning ball 63 horizontally, roughly aligning it with the transformer's central axis. When the equipment is running, after the clamping and fixing mechanism 7 drives the transformer to rotate and approach, the transformer presses against the positioning ball 63. Under the thrust of the abutting support component 64, the positioning ball 63 presses tightly against the transformer end face. Since the positioning ball 63 is rotatable, it forms rolling friction with the rotating transformer surface, providing stable axial and radial limits while avoiding scratching the transformer surface. By setting the positioning rod 62, the positioning ball 63 on the positioning rod 62 corresponds to the transformer's tape winding position. When the transformer rotates to the position of the positioning ball 63, the positioning ball 63 abuts against the transformer's free end, thus providing good stable support for the transformer and reducing the possibility of shaking or offset when the transformer rotates. The rotatable positioning ball 63 design changes sliding friction into rolling friction, reducing wear and heat accumulation between the rotating transformer and the transformer, protecting the integrity of the transformer surface. At the same time, the adjusting component 65 can drive the positioning rod 62 to move laterally, thus adapting to multi-variety production.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The abutment support assembly 64 includes an adjusting bolt 642 threadedly connected to the positioning rod 62. The positioning rod 62 has an adjusting hole that passes through the positioning rod 62. An abutment spring 641 is installed in the adjusting hole on the positioning rod 62. The two ends of the abutment spring 641 abut against the adjusting bolt 642 and the positioning ball 63, respectively.

[0034] Based on the transformer's weight and the expected winding speed, the operator uses a tool to rotate the adjusting bolt 642. Tightening the bolt increases the compression of the abutment spring 641 and the tightening force of the positioning ball 63 on the transformer, which is suitable for heavier or higher-speed transformers. Unscrewing the bolt reduces the tightening force, which is suitable for lighter or more fragile transformers. During operation, the elastic force of the abutment spring 641 continuously acts on the transformer through the positioning ball 63, forming a flexible and buffered support. The support force can be changed by simple bolt adjustment, allowing the equipment to flexibly cope with different operating conditions and transformers to achieve the best support effect. At the same time, the introduction of the abutment spring 641 makes the support elastic rather than rigid, which can absorb the small vibrations generated when the transformer rotates, further stabilizing the winding process and improving the winding quality.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The adjustment component 65 includes a sliding seat 651 slidably connected to a support 61, an adjustment threaded rod 653 rotatably connected to the support 61, the adjustment threaded rod 653 passing through the sliding seat 651 and threadedly connected to the sliding seat 651, and an adjustment motor 652 fixed on the support 61, the output end of the adjustment motor 652 being fixedly connected to the adjustment threaded rod 653.

[0036] When the position of the positioning ball 63 on the positioning rod 62 needs to be adjusted, the operator sends a command to the adjusting motor 652 through the control panel 9. The adjusting motor 652 rotates forward or backward, driving the adjusting threaded rod 653 to rotate, thereby driving the sliding seat 651 and the entire positioning mechanism to move forward or backward precisely along the guide rail until the positioning ball 63 reaches the preset working position. By using the adjusting motor 652 to drive the adjusting threaded rod 653 to drive the sliding seat 651, and the sliding seat 651 to drive the positioning rod 62, the positioning ball 63 can be automatically and precisely controlled. The accuracy is much higher than that of manual adjustment, and it can be linked with the equipment control system to realize the rapid call of different product parameters.

[0037] Reference Figure 2 , Figure 5 and Figure 6 The clamping and fixing mechanism 7 includes a support plate 71 fixed to the output end of the self-rotating motor 4. Two symmetrical clamping plates 72 are provided on the side of the support plate 71 away from the self-rotating motor 4. Each clamping plate 72 is provided with a connecting rod 73. A moving block 74 is provided on the support plate 71. One end of the connecting rod 73 is rotatably connected to the moving block 74. A push rod 77 is fixed on the moving block 74. An abutting rod 78 is fixed on the push rod 77. A sliding support assembly 75 is provided between the moving block 74 and the support plate 71. A spacing assembly 76 is provided between the clamping plate 72 and the support plate 71.

[0038] Based on the thickness of the transformer, the initial distance between the two clamping plates 72 is pre-adjusted using the spacing component 76. When the transformer is placed between the two clamping plates 72, the transformer pushes the contact plate, and the contact rod 78 drives the push rod 77, which in turn drives the moving block 74. The moving block 74 moves on the support plate 71 under the support of the sliding support component 75. The moving block 74 pulls the connecting rod 73, which in turn drives the two spacing components 76. The two spacing components 76 then clamp the clamping plate 72 onto the transformer. The self-rotating motor 4 drives the entire clamping and fixing mechanism 7 and the clamped transformer to rotate. By using symmetrical connecting rods 73 to drive the clamping plate 72, when the transformer pushes the moving block 74, the moving block 74 drives the connecting rod 73, which in turn clamps the transformer onto the clamping plate 72. This further secures the transformer and reduces the possibility of movement or displacement during rotation. It also has a spacing adjustment function, and one set of clamps can adapt to various transformers within a certain size range, making it highly versatile.

[0039] Reference Figure 2 , Figure 5 and Figure 6 The sliding support assembly 75 includes two connecting blocks 751 symmetrically fixed on the support plate 71. A support slide rod 752 is fixed between the two connecting blocks 751. The support slide rod 752 passes through the moving block 74 and is slidably connected to the moving block 74. A return spring 753 is sleeved on the support slide rod 752. The two ends of the return spring 753 abut against the connecting block 751 and the moving block 74 respectively. A fixing member 754 is provided on the moving block 74.

[0040] When clamping is required, external force pushes the moving block 74 to compress the return spring 753 and slide it along the support slide rod 752 to achieve clamping. Once clamped in place, the fixing member 754 moves to lock the moving block 74 in that position. When it is necessary to release, first release the locking of the fixing member 754. The elastic force of the return spring 753 will push the moving block 74 to return to its original position, thereby causing the clamping plate 72 to open. By allowing the support slide rod 752 to provide precise linear guidance for the moving block 74, and at the same time using the return spring 753 to support the moving block 74, the smoothness and coaxiality of the clamping action can be ensured. The return spring 753 ensures that the clamp can open automatically and quickly when the external force is lost, improving safety and work efficiency.

[0041] Reference Figure 2 , Figure 5 and Figure 6The fixing component 754 includes two connecting blocks 7541 symmetrically fixed on the support plate 71. A fixing rod 7542 is fixed between the two connecting blocks 7541. The fixing rod 7542 has several evenly distributed fixing grooves. A plug-in rod 7543 is slidably connected to the moving block 74. The plug-in rod 7543 has fixing grooves corresponding to the fixing grooves. The fixing grooves 1 and 2 face opposite directions. A limiting spring 7544 is sleeved on the plug-in rod 7543. Both ends of the limiting spring 7544 are fixedly connected to the moving block 74 and the plug-in rod 7543.

[0042] When the movable block 74 is pushed toward the fixed rod 7542, the plug rod 7543 is in a retracted state under the action of the limit spring 7544. After moving to the desired position, the plug rod 7543 is pushed manually or by a small cylinder so that the second fixed tooth groove on it meshes with the first fixed tooth groove on the fixed rod 7542. Since the teeth are opposite, the movable block 74 cannot move in the opposite direction and is reliably locked. When it needs to be released, the plug rod 7543 is pulled outward again to overcome the force of the limit spring 7544 and separate the teeth. The movable block 74 then retracts under the action of the return spring 753. Through the ratchet plug rod 7543 and the fixed rod 7542, the movable block 74 is allowed to move forward in one direction and can be locked in multiple positions, thus providing stable locking for the transformer. It has strong anti-vibration ability and is very reliable. The uniform distribution of the teeth means that the movable block 74 can be locked in multiple stroke positions, increasing the flexibility of clamping range adjustment.

[0043] Reference Figure 2 and Figure 5 The spacing assembly 76 includes an adjusting plate 763 disposed on the clamping plate 72. The end of the connecting rod 73 away from the moving block 74 is rotatably connected to the adjusting plate 763. A spacing bolt 761 is threadedly connected to the adjusting plate 763. The spacing bolt 761 passes through the adjusting plate 763 and is rotatably connected to the clamping plate 72. A limit rod 762 is fixed on the clamping plate 72. The limit rod 762 passes through the adjusting plate 763 and is slidably connected to the adjusting plate 763.

[0044] When it is necessary to adjust the initial spacing between the two clamping plates 72, use a tool to rotate the spacing bolt 761. Since the limit rod 762 restricts the rotation of the clamping plate 72, rotating the bolt will force the clamping plate 72 to move forward or backward in a straight line relative to the adjusting plate 763, changing the position of the clamping plate 72 relative to the center of the support plate 71. After adjusting one side, adjust the other side in the same way to set the initial opening of the fixture. By allowing the clamping plates 72 to be finely adjusted independently, the central symmetry and opening size of the fixture can be precisely controlled, adapting to asymmetrical transformers or achieving precise centering.

[0045] Working principle: The operator places the transformer between the two clamping plates 72 at one workstation. The placement of the transformer will push the abutment rod 78. The abutment rod 78 drives the push rod 77 and the moving block 74 to slide on the support slide rod 752 and compress the return spring 753. The movement of the moving block 74 pulls the two adjusting plates 763 through the two connecting rods 73, forcing the two clamping plates 72 to move towards each other, thereby clamping the transformer. Then, the operator pulls out the tape from the tape roll 10 and manually sticks it on the transformer.

[0046] After the equipment is started, the turntable 3 rotates, moving the station holding the transformer to the working position, directly facing the positioning rod 62. At this time, the adjusting motor 652 can drive the adjusting threaded rod 653 to rotate, causing the sliding seat 651 and the positioning rod 62 to move, so that the positioning ball 63 at the front end of the positioning rod 62 is aligned with the center of the transformer. Under the thrust of the contact spring 641, the positioning ball 63 is tightly pressed against the free end of the transformer. Then, the self-rotating motor 4 of this station starts, driving the clamped transformer to rotate at a constant speed through the support plate 71, and the tape is wound.

[0047] While the winding is in progress, the operator can load the next material at the opposite workstation. When the winding is completed, the turntable 3 rotates again, exchanging the two workstations. The newly rotated transformer is held in place by the positioning ball 63, and the tape on its surface is connected to the tape on the already wound transformer under the rotational traction. At this time, the reciprocating device 8 drives the cutting blade 5 at its front end to move forward and cut the tape. Immediately afterwards, the self-rotating motor 4 of the new workstation starts immediately to start a new round of winding, while the operator can remove the finished transformer from the workstation it left. The cycle continues in this way.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
