Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a transformer coil tape winding machine and transformer coil tape winding equipment. Background Technology
[0002] High-frequency transformers are widely used in switching power supplies, electronic ballasts, high-frequency inverter welding machines, and other fields. They operate based on the principle of electromagnetic induction. When high-frequency alternating current is applied to the primary winding, an alternating magnetic field is generated. This alternating magnetic field is coupled to the secondary winding through the magnetic core, inducing an electromotive force in the secondary winding, thereby realizing the transfer of electrical energy from the primary to the secondary winding.
[0003] When a high-frequency transformer is operating, a significant voltage difference exists between the primary and secondary windings, which can easily lead to electrical breakdowns and short circuits, resulting in frequent transformer failures and compromising safety. As is widely accepted in the industry, wrapping insulating tape between the primary and secondary windings effectively solves these problems. Therefore, our company has recently developed a transformer coil tape wrapping device. Summary of the Invention
[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of this utility model collected relevant information, conducted multiple evaluations and considerations, and carried out continuous experiments and modifications by technical personnel with many years of R&D experience in this industry, which ultimately led to the emergence of the transformer coil tape winding machine.
[0005] This utility model relates to a transformer coil tape winding machine, in which the primary and secondary windings are isolated by means of multi-layered overlapping rolled tape. The transformer coil tape winding machine includes a tape release device, a tape guiding unit, a tape winding mechanism, and a transformer unloading mechanism arranged sequentially along the upstream and downstream directions. The tape winding mechanism includes a clamping fixture, a rotating shaft, and a first power unit. The clamping fixture is used to load and clamp the transformer, and it is assembled integrally with the rotating shaft. The first power unit serves as the power source for the rotating shaft. The tape to be wound is released via the tape release device, and it winds through the tape winding mechanism until the transformer is completely wrapped with tape. Subsequently, the transformer unloading mechanism actuates to remove the transformer from the clamping fixture. During the process of the transformer being rolled by the tape, the rotating shaft performs circumferential rotation due to the rotational torque from the first power unit. At the same time, the rotating shaft performs reciprocating translational motion due to the driving force from the first power unit, so that the tape can be rolled layer by layer on the circumferential sidewall of the transformer.
[0006] As a further improvement to the technical solution disclosed in this utility model, the first power unit includes a support frame, a sliding frame, a translational power output subunit, and a torque output subunit. The translational power output subunit serves as a connecting transition between the support frame and the sliding frame. During the operation of the translational power output subunit, the sliding frame is subjected to a driving force and thus performs a reciprocating translational motion relative to the support frame. The rotational shaft traverses the sliding frame and uses the sliding frame as its mounting base. The torque output subunit applies torque to the rotational shaft and also uses the sliding frame as its mounting base.
[0007] As a further improvement to the technical solution disclosed in this utility model, the translational force output subunit is a rodless cylinder. The rodless cylinder includes a left fixed stop, a right fixed stop, a movable slider, a cylinder barrel, and a guide rod. The left and right fixed stops are positioned opposite each other and are both detachably fixed to the support frame. The movable slider is detachably fixed to the sliding frame. During the operation of the rodless cylinder, the movable slider performs a reciprocating sliding motion along the guide rod due to the aerodynamic force from the cylinder barrel. Simultaneously, the sliding frame performs a reciprocating translational motion due to the drag force from the movable slider.
[0008] As a further improvement to the technical solution disclosed in this utility model, the torque output subunit includes a rotary motor and a synchronous belt force transmission mechanism. The rotary motor uses a sliding frame as its mounting base and outputs torque toward the rotation axis by means of the synchronous belt force transmission mechanism.
[0009] As a further improvement to the technical solution disclosed in this utility model, the transformer coil tape winding machine also includes a tape pressing and shaping mechanism. The tape pressing and shaping mechanism is matched with the tape winding mechanism. During the process of the transformer being wound with tape, at the instant the clamping fixture is moved to its left limit position, the posture of the tape pressing and shaping mechanism changes, and the wound and shaped tape layer is compacted by the pressing force from the tape pressing and shaping mechanism.
[0010] As a further improvement to the technical solution disclosed in this utility model, the tape pressing and shaping mechanism includes a pressure roller, a swing arm assembly, and a second power unit. The pressure roller is detachably fixed to the swing arm assembly and has a circumferential rotational degree of freedom. The second power unit serves as the power source for the swing arm assembly, enabling the swing arm assembly to perform a circumferential oscillating motion until the tape is pressed against the pressure roller.
[0011] As a further improvement to the technical solution disclosed in this utility model, the tape release device is arranged above the tape winding mechanism, and includes a support frame, a mandrel, and a tray. The mandrel supports the tray and is assembled with the support frame by a mating method. During the process of the tape being stretched and released due to the dragging force, the tray and the mandrel synchronously perform circumferential rotation.
[0012] As a further improvement to the technical solution disclosed in this utility model, the belt guiding unit includes a first guide roller and a second guide roller arranged sequentially along the upstream and downstream directions. During the process of the transformer being wound by the belt, the belt to be wound is sequentially wound around the first guide roller and the second guide roller and thus directionally guided to the belt winding mechanism.
[0013] As a further improvement to the technical solution disclosed in this utility model, the transformer unloading mechanism includes a parallel-opening and closing pneumatic finger cylinder and a third power unit. The parallel-opening and closing pneumatic finger cylinder is located below the tape winding mechanism and is aligned with the clamping fixture. Driven by the third power unit, the parallel-opening and closing pneumatic finger cylinder performs translational motion in the front-to-back direction and / or lifting motion in the up-down direction. Assisted by the opening and closing motion of the two opposite fingers of the parallel-opening and closing pneumatic finger cylinder, the transformer can be removed from the clamping fixture.
[0014] In addition, the present invention also discloses a transformer coil tape winding device, which includes the above-mentioned transformer coil tape winding machine, and thus has two tape winding stations at the same time.
[0015] In practical applications, the transformer coil tape winding machine disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:
[0016] 1) During the process of the transformer being wound with conveyor tape, the rotating shaft used to load the transformer performs a compound motion (including circumferential rotation and reciprocating translational motion). The reciprocating translational motion helps the conveyor tape to form a tighter and neater structure during the winding process, reducing the generation of gaps and wrinkles, making the tape winding more secure and less prone to loosening or falling off. Especially when the transformer is subjected to vibration or external forces, the conveyor tape can better maintain its fixing and insulation functions.
[0017] 2) Similarly, thanks to the composite motion performed by the transformer, the tape can be wound more evenly on the transformer surface, avoiding the tape from being concentrated in certain areas. The transformer surface can be completely covered, eliminating weak points in insulation, reducing the risk of partial discharge or leakage, thereby enhancing the insulation and protection performance of the transformer, extending the service life of the transformer, and improving its operational safety and reliability.
[0018] 3) Also benefiting from the composite motion performed by the transformer, a larger transformer surface area is covered in the same amount of time, reducing the time and number of windings required, which can improve the winding efficiency of the tape to a certain extent.
[0019] 4) No manual intervention is required during the transformer tape winding process, which can ensure the accuracy and consistency of the winding operation, improve the stability of transformer product quality, and reduce the labor intensity of workers to a certain extent.

Detailed Implementation
[0035] In the description of this utility model, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0036] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 , Figure 3 The diagram shows the structure of the transformer coil tape winding equipment disclosed in this utility model. It is mainly assembled from several parts, including a frame 1, a left-mounted transformer coil tape winding machine 2, and a right-mounted transformer coil tape winding machine 3. The frame 1 is placed horizontally and lies horizontally, serving as the mounting base for the left-mounted and right-mounted transformer coil tape winding machines 2 and 3. Each of the left-mounted and right-mounted transformer coil tape winding machines 2 and 3 independently occupies a tape winding station. In practical applications, one worker can simultaneously manage both tape winding stations, meaning that two transformers can undergo tape winding operations synchronously, significantly improving work efficiency.
[0037] Depend on Figure 2 , Figure 3 As can also be clearly seen in the diagram, the left-side transformer coil tape winding machine 2 and the right-side transformer coil tape winding machine 3 share a power source (i.e., the first power unit 233 described below), and the output torque is proportionally distributed by means of a force transmission mechanism to ensure the consistency of the winding process of the two independent tape winding stations.
[0038] Furthermore, similarly Figure 1 , Figure 2 , Figure 3 As shown, the left-side transformer coil wrapping machine 2 and the right-side transformer coil wrapping machine 3 have exactly the same design structure and assembly method. For the sake of brevity, this embodiment will only use the left-side transformer coil wrapping machine 2 as an example for detailed explanation, as follows:
[0039] Figure 4 , Figure 5 , Figure 6 The diagram shows the structure of the left-side transformer coil tape winding machine disclosed in this utility model. It can be seen that it mainly consists of several parts, including a tape release device 21, a tape guiding unit 22, a tape winding mechanism 23, and a transformer unloading mechanism 24, arranged sequentially along the upstream and downstream directions. Figure 8 , 9 As shown, the tape winding mechanism 23 includes a clamping fixture 231, a rotating shaft 232, and a first power unit 233. The clamping fixture 231 is used to load and clamp the transformer, and it is assembled with the rotating shaft 232 as a whole. The first power unit 233 is used as the power source for the rotating shaft 232.
[0040] In practical applications, the tape to be wound is released via tape release device 21, and under the guiding force of tape guide unit 22, it winds around tape winding mechanism 23 until the transformer is completely wound with tape. Subsequently, transformer unloading mechanism 24 actuates to remove the transformer from clamping fixture 231. During the process of the transformer being wound with tape, rotating shaft 232 performs circumferential rotation due to the rotational torque from first power unit 233. At the same time, rotating shaft 232 performs reciprocating translational motion due to the driving force from first power unit 233, allowing the tape to be wound layer by layer on the circumferential sidewall of the transformer.
[0041] In practical applications, the transformer coil tape winding machine disclosed in this utility model has achieved at least the following beneficial technical effects, specifically:
[0042] 1) During the process of the transformer being wound with the conveyor belt, the rotating shaft 232 used to load the transformer performs a compound motion (including circumferential rotation and reciprocating translation). The reciprocating translation helps the conveyor belt form a tighter and neater structure during the winding process, reducing gaps and wrinkles, making the conveyor belt more secure and less prone to loosening or falling off. Especially when the transformer is subjected to vibration or external force, the conveyor belt can better maintain its fixing and insulation functions.
[0043] 2) Similarly, thanks to the composite motion performed by the transformer during the tape winding process, the tape can be wound more evenly on the transformer surface, avoiding the tape from being concentrated in certain areas. The transformer surface can be completely covered, eliminating weak points in insulation, reducing the risk of partial discharge or leakage, thereby enhancing the insulation and protection performance of the transformer, extending the service life of the transformer, and improving its operational safety and reliability.
[0044] 3) Similarly, thanks to the composite motion performed by the transformer, a larger transformer surface area is covered in the same amount of time, reducing the time and number of winding operations required, which can improve the winding efficiency of the tape to a certain extent.
[0045] It is particularly important to note that no manual intervention is required throughout the entire process of the transformer being wrapped with tape. This not only effectively ensures the accuracy and consistency of the wrapping operation, which helps to improve the stability of transformer product quality, but also reduces the labor intensity of workers to a certain extent.
[0046] Based on design common sense, the first power unit 233 can adopt various design structures to drive the winding action of the left-side transformer coil tape winding machine 2. However, here we recommend an implementation scheme that is simple in design, easy to manufacture and implement, and conducive to achieving a high degree of consistency in the winding actions of the left-side transformer coil tape winding machine 2 and the right-side transformer coil tape winding machine 3. Specifically: Figure 8 , Figure 9 As shown, the first power unit 233 mainly consists of a support frame 2331, a sliding frame 2332, a translational power output subunit 2333, and a torque output subunit 2334. The translational power output subunit 2333 serves as a connecting transition between the support frame 2331 and the sliding frame 2332. During the operation of the translational power output subunit 2333, the sliding frame 2332 is subjected to a driving force and performs a reciprocating translational motion relative to the support frame 2331. The rotation shaft 232 traverses the sliding frame 2332 and uses the sliding frame 2332 as its mounting base. The torque output subunit 2334 applies torque to the rotation shaft 232 and also uses the sliding frame 2332 as its mounting base.
[0047] It should be noted here that, similarly... Figure 2 , Figure 3 As shown, the first power unit 233 is used as the winding power source for the left transformer coil tape winding machine 2 and the right transformer coil tape winding machine 3. In practical applications, during the operation of the translational power output subunit 2333, the sliding frame 2332 performs translational motion due to the lateral thrust. At the same time, the tape winding mechanism 23 belonging to the left transformer coil tape winding machine 2 and the right transformer coil tape winding machine 3 respectively performs displacement motion synchronously. During the operation of the torque output subunit 2334, the rotating shaft 232 belonging to the left transformer coil tape winding machine 2 and the right transformer coil tape winding machine 3 respectively performs circumferential rotational motion synchronously due to the equivalent torque, so that the tape can be wound and formed layer by layer on the circumferential sidewalls of the two transformers.
[0048] As a further refinement of the above technical solution, such as Figure 8 , Figure 9 , Figure 10As shown, the translational force output subunit 2333 is preferably a rodless cylinder 23331. The rodless cylinder 23331 mainly consists of a left fixed stop 233311, a right fixed stop 233312, a movable slider 233313, a cylinder barrel 233314, and a guide rod 233315. The left fixed stop 233311 and the right fixed stop 233312 are positioned opposite each other and are both detachable for fixing to the support frame 2331. The movable slider 233313 is detachable for fixing to the sliding frame 2332. During the operation of the rodless cylinder 23331, the movable slider 233313 performs a reciprocating sliding motion along the two opposing guide rods 233315 due to the aerodynamic force from the cylinder 233314. Simultaneously, the sliding frame 2332 performs a reciprocating translational motion due to the drag force from the movable slider 233313.
[0049] It is known that synchronous belt force transmission mechanisms are meshing transmissions, where the belt teeth and pulley teeth mesh correctly without missing steps, achieving slip-free synchronous transmission. They possess advantages such as accurate transmission ratio, smooth transmission, and compact structure. Therefore, as a further optimization of the aforementioned technology, such as... Figure 8 , Figure 9 As shown, the torque output subunit 2334 includes a rotary motor 23341 and a synchronous belt force transmission mechanism 23342. The rotary motor 23341 uses the sliding frame 2332 as a mounting base and outputs torque toward the rotating shaft 232 by means of the synchronous belt force transmission mechanism 23342.
[0050] Furthermore, by Figure 1 , Figure 2 , Figure 3 As can be clearly seen from the diagram, the left-side transformer coil tape winding machine 2 is also equipped with a tape pressing and shaping mechanism 25. The tape pressing and shaping mechanism 25 is matched with the tape winding mechanism 23. As... Figure 12 , Figure 13As shown, the tape pressing and shaping mechanism 25 mainly consists of several parts, including a pressure roller 251, a swing arm assembly 252, and a second power unit 253. The pressure roller 251 is detachably fixed to the swing arm assembly 252 and has a circumferential rotational freedom. The second power unit 253 (preferably a cylinder) serves as the power source for the swing arm assembly 252, enabling it to perform a circumferential oscillating motion until the tape is pressed against the pressure roller 251. During the process of the transformer being wound with tape, the second power unit 253 is activated the instant the transformer is displaced to the left limit position. The swing arm assembly 252 performs a circumferential oscillating motion due to the rotational torque. The wound tape layer is compacted by the pressing force from the pressure roller 251, further contributing to a tighter and neater structure of the tape during the winding process, and making the tape winding more secure and less prone to loosening or falling off.
[0051] As Figure 1 , Figure 2 , Figure 3 As shown, the tape release device 21 is arranged above the tape winding mechanism 23, and is mounted on the frame 1. Figure 7 As shown, the tape release device 21 includes a support frame 211, a spindle 212, and a tray 213. The spindle 212 supports the tray 213 and is assembled with the support frame 211 by a plug-in method. During the process of the tape being stretched and released due to the drag force, the tray 213 and the spindle 212 synchronously perform circumferential rotation.
[0052] Furthermore, similarly Figure 7 As shown, the tape guiding unit 22 includes a first guide roller 221 and a second guide roller 222. Both the first guide roller 221 and the second guide roller 222 are mounted and fixed on a support frame 211, and are arranged sequentially from top to bottom. During the process of the transformer being wound with tape, the tape to be wound sequentially passes through the first guide roller 221 and the second guide roller 222, thus being directionally guided to the tape winding mechanism 23.
[0053] like Figure 11 As shown, the transformer unloading mechanism 24 includes a parallel-opening and closing pneumatic finger cylinder 241 and a third power unit 242. The parallel-opening and closing pneumatic finger cylinder 241 is located below the tape winding mechanism 23 and is aligned with the clamping fixture 231. In practical applications, the parallel-opening and closing pneumatic finger cylinder 241 performs translational movement in the front-to-back direction and / or lifting movement in the up-down direction due to the driving force from the third power unit 242. With the assistance of the opening and closing movement of the two opposite fingers of the parallel-opening and closing pneumatic finger cylinder 241, the transformer can be removed from the clamping fixture 231.
