Description

Technical Field

[0001] The present invention relates to the technical field of transformer production equipment, in particular to a transformer coil winding machine with multiple specifications. Background Art

[0002] In power systems, instrument transformers (MTs) are key devices used in measurement and protection. The performance of MTs depends largely on the quality of their coils, and winding machines are the core tool that determines this quality.

[0003] Current transformer coil winding machines on the market generally use a fixed-shape positioning method to wind the coils. This traditional positioning method has significant limitations and is only suitable for winding coils of specific shapes. For example, when working with toroidal coils, the positioning mechanism is designed based on the size and shape of the ring, making it ineffective for positioning rectangular coils. Similarly, winding machines designed for rectangular coils cannot accurately position horseshoe-shaped or semicircular coils for winding due to their different shapes.

[0004] This situation means that manufacturers often need to purchase multiple special winding machines when producing transformer coils of different shapes, which greatly increases equipment costs and the company's capital investment. At the same time, multiple different types of winding machines also increase the difficulty of equipment management and maintenance. In addition, since each winding machine can only produce coils of a single shape, the production process lacks flexibility and cannot quickly respond to the market's diverse demand for transformer coils of different shapes. Summary of the Invention

[0005] The present invention aims to solve the problems in the prior art and provides a multi-specification transformer coil winding machine, which can position coils of different shapes, thereby realizing the winding of coils of multiple different shapes and reducing the required cost.

The lifting device can be an electric cylinder when in use.

[0013] Preferably, the linear module is composed of two linear motors, one of which is arranged horizontally, and another linear motor is arranged vertically on the output component of the linear motor.

[0031] The linear module 311 is composed of two linear motors, one of which is arranged horizontally, and another linear motor is arranged vertically on the output component of the linear motor. The combination of the horizontal and vertical linear motors forms a two-dimensional mobile platform to achieve precise positioning of the placement plate 32. Especially when processing horseshoe-shaped and semi-circular coils, the current position can be adjusted to switch the working position.

[0032] The clamping member 39 includes a symmetrically arranged rotating plate 2 393 and a symmetrically arranged driving device 4 391. The two rotating plates 2 393 are both rotatably arranged on the placement plate 32 through a rotating shaft. The two driving devices 4 391 are fixed under the placement plate 32. The two driving devices 4 391 are respectively connected to the two rotating shafts through two transmission components 2 392. The ends of the two rotating plates 2 393 away from the rotating shaft are both provided with a rotating clamping shaft 394. The clamping shaft 394 is provided with a roller 395. The roller 395 is made of rubber material when in use. The clamping member 39 can clamp the two ends of the horseshoe coil and clamp the inside and outside of the semi-circular coil.

[0033] A driving device five 397 is fixed on one of the rotating plates two 393. The output shaft of the driving device five 397 is connected to the closest clamping shaft 394 through the transmission component three 396. The driving device five 397 drives the roller 395 to rotate through the transmission component three 396, and can actively send the end of the semi-annular coil to the winding mechanism 2. Its transmission component one 372, transmission component two 392 and transmission component three 396 are all transmission parts composed of multiple gears when in use, and the multiple gears are meshed and connected to transmit power.

[0034] Electrical control part: This winding machine is equipped with a controller 4, a relay module 5 and a control interface 6 (the control interface 6 can be a human-computer interaction interface when in use). The controller 4 serves as the control core of the equipment and is responsible for executing the control program, processing the feedback data and sending control instructions to each execution component. The relay module 5 receives signals from the controller 4 to realize the on-off control of the power supply 7 of each driving device, the lifting device 316 and the telescopic device 382. An encoder is installed on the drive shaft of the wrapping pulley 35 or the belt 33 to record the rotation angle and displacement information in real time. According to the preset rectangular coil size parameters (length and width), the system pre-calculates the rotation angle and displacement stroke corresponding to each side length. During the winding process of the rectangular coil, the encoder transmits the rotation angle and displacement data to the controller 4 in real time. The controller 4 calculates the coil position currently contacted by the wrapping pulley 35 based on the received encoder data. When the rotation angle reaches the stroke corresponding to the preset side length, the controller 4 triggers the corresponding motor (such as the drive device three 371) to drive the rotating plate 373 to rotate through the transmission component one 372, thereby adjusting the spacing of the wrapping pulley 35 to achieve precise adjustment; Overall control process: After the system is powered on, the controller 4 executes a self-test program, initializes each input / output port, reads the preset parameters, and controls each drive device to return to the initial position to prepare for the subsequent winding operation. The operator inputs information such as the coil type (rectangular / annular / horseshoe / semi-annular) and size parameters through the human-machine interface. According to the preset program, the controller 4 calls the corresponding control strategy based on the input parameters to determine the initial action and operating parameters of each component.

[0035] Rectangular / annular coil: Controller 4 controls driving device 3 371 to start, driving transmission pulley 34 to rotate, thereby causing belt 33 to operate, and starting to drive the rectangular or annular coil to rotate. When the rectangular coil rotates, the encoder feeds back the value to controller 4 in real time. Based on the feedback signal, controller 4 controls the telescopic device 382 of adjustment member 38 through relay module 5, and adjusts the position of adjustment wheel 384 in real time. It can more accurately adjust the position of wrapping pulley 35 according to the change in the side length of the rectangular coil, ensuring that the belt 33 and the rectangular coil always maintain a good fit, further improving the uniformity and stability of the winding; Horseshoe coil: The controller 4 first controls the horizontal linear motor in the linear module 311 to start, driving the placement plate 32 to move away from the winding mechanism 2 to the specified position, and then controls the lifting device 316 and the driving device four 391 to start. The lifting device 316 drives the placement plate 32 to move down a certain distance, and then the driving device four 391 drives the rotating plate two 393 to rotate toward the winding mechanism 2 through the transmission component two 392, so that the two rollers 395 can accurately clamp the two ends of the horseshoe coil. When the winding mechanism 2 winds the horseshoe coil, it can move and wind the clamped horseshoe coil through the linear module 311.

[0036] Semi-annular coil: The controller 4 controls the horizontal linear motor, the driving device 1 314, the longitudinal linear motor and the driving device 4 391 in sequence to work together. First, the placement plate 32 is moved away from the winding mechanism 2 by the horizontal linear motor to avoid interference when the placement plate 32 is rotated. Then the driving device 1 314 is started to drive the rotating plate 1 315 to rotate. At the same time, the driving device 4 391 and the lifting device 316 are also started, so that the rotating plate 2 393 moves down and rotates. When the driving device 1 314 drives the rotating plate 1 315 to rotate, it can drive the placement plate 32 to rotate. After the placement plate 32 rotates, the longitudinal linear motor moves again, so that the roller 395 moves to one side of the winding mechanism 2. Finally, the horizontal linear motor moves the placement plate 32 toward the winding mechanism 2, so that the clamping roller is close to the side of the winding part, thereby clamping the semi-annular coil.

[0037] The linear motor, drive device 1 314 , drive device 2 36 , drive device 3 371 , drive device 4 391 , drive device 5 397 , lifting device 316 and telescopic device 382 in the linear module 311 are all connected to the external power supply 7 through the relay module 5 , and the current is controlled by the relay module 5 .

[0038] When the transformer coil winding machine is in operation, the transformer coil to be wound is first placed on the placement plate 32 of the fixing member 3. Then, the operator inputs the type and relevant size parameters of the coil through the human-machine interface. The controller 4 calls the corresponding control program based on the input information. Then, according to the shape of the coil, the position and posture of the placement plate 32 are adjusted through the switching component 31. At the same time, the coil is clamped and fixed by the clamping member 39 (for rectangular and annular coils, the rotation is mainly driven by the belt 33; for horseshoe-shaped and semi-annular coils, the clamping member 39 is used for clamping). After that, the driving device 3 371 is started. The transmission pulley 34 is driven to rotate, causing the belt 33 to run, thereby driving the coil to move, and the winding mechanism 2 begins to wind the coil. During the winding process, for rectangular coils, according to the change in its side length, the driving device three 371 controls the movement of the wrapping pulley 35, and the adjustment part 38 adjusts the tension of the belt 33 in real time; for horseshoe-shaped and semi-annular coils, through the further coordinated action of the switching component 31 and the clamping part 39, the stable and accurate position of the coil during the winding process is ensured. At the same time, the controller 4 monitors the feedback data in real time, adjusts and optimizes the operating status of each component of the equipment, so as to ensure the smooth progress of the winding work.

[0039] Fixing 3: The placement plate 32 serves as a support platform for the coil. Drive pulleys 34 and wrapping pulleys 35 on either side of the plate cooperate with belt 33. Driven by drive device 371, belt 33 rotates, thereby moving the coil. The symmetrical arrangement of drive pulleys 34 and wrapping pulleys 35 ensures the stability and uniformity of belt 33's transmission. Driving member 37: When a rectangular coil is being wound and the position of the wrapping pulley 35 needs to be adjusted, driving device three 371 drives the rotating plate 373 to rotate via transmission assembly one 372. The guide hole 374 on the rotating plate 373 interacts with the connecting member (driving rod 375 and connecting rod two 377 are connected by connecting rod one 376). The driving rod 375 moves along the limiting slot 321, driving connecting rod two 377 to move via connecting rod one 376, thereby moving the wrapping pulley 35 on the placement plate 32 to adapt to the different side lengths of the rectangular coil. During this process, the adjusting member 38 automatically adjusts according to the changes in the tension of the belt 33. Adjusting member 38: During the movement of the wrapping pulley 35, the tension of the belt 33 will change. When the wrapping pulley 35 moves away from the transmission pulley 34 to tighten the belt 33, the telescopic device 382 receives a control signal, controls the output shaft to retract, and drives the moving block 383 and the adjusting wheel 384 to move away from the belt 33, thereby reducing the tension of the belt 33; conversely, when the wrapping pulley 35 approaches the transmission pulley 34 to loosen the belt 33, the telescopic device 382 controls the output shaft to shorten, and drives the adjusting wheel 384 to move toward the belt 33, thereby increasing the tension of the belt 33. Through this real-time adjustment, the belt 33 is ensured to always maintain appropriate tension during the winding process.

[0040] Switch component 31: Linear module 311: The linear module 311 enables precise adjustment of the position of the movable plate 312. When winding horseshoe-shaped and semi-annular coils, the transverse linear motor first moves the placement plate 32 away from the winding mechanism 2 to provide space for subsequent rotation operations. When precise position adjustment is required, the longitudinal linear motor is activated to achieve more accurate positioning. Driving device 314 and rotating plate 315: Driving device 314 can drive rotating plate 315 to rotate. When winding a semi-annular coil, the rotation of rotating plate 315 can drive the placement plate 32 to rotate, so that the roller 395 and other components on the placement plate 32 are adjusted to a suitable angle, which facilitates the clamping and winding operations of the semi-annular coil. Lifting device 316: When winding horseshoe-shaped and semi-toroidal coils, lifting device 316 drives the placement plate 32 up and down according to control signals, adjusting the height of the coil and ensuring the coil's accurate position during the winding process. For example, when winding a horseshoe-shaped coil, lifting device 316 moves the placement plate 32 downward a certain distance, allowing roller 395 to better grip the coil ends.

[0041] Clamping piece 39: Driving device four 391 and transmission component two 392: When winding horseshoe-shaped and semi-circular coils, driving device four 391 is started, and the turn plate two 393 is driven to rotate through the transmission component two 392. The rotation of the turn plate two 393 moves the clamping shaft 394 and the roller 395 to the appropriate position to clamp the coil. For example, when winding a horseshoe-shaped coil, the turn plate two 393 rotates toward the winding mechanism 2, so that the two rollers 395 can clamp the two ends of the horseshoe-shaped coil.

[0042] Driving device five 397 and transmission component three 396: When winding a semi-annular coil, driving device five 397 is started, and the clamping shaft 394 connected to it is driven to rotate through transmission component three 396, and then the roller 395 is driven to rotate. The rotation of the roller 395 can send the end of the semi-annular coil toward the winding mechanism 2, thereby facilitating the winding operation of the winding mechanism 2.
