[0014] S2. Setting parameters: Set the basic parameters of winding through the human-computer interaction interface, including the number of winding turns, winding speed and tension parameters; the setting of winding speed should take into account the material, width, thickness of the strip and the performance of the equipment.

[0030] Specifically,

[0031] The unloading tray is connected to the arc transition wheel through the superconducting tape. The arc transition wheel is installed on the table to ensure that the tape can enter the winding system in the correct direction. The unloading tray is a flat disc structure. There is a round hole in the center of the disc body for installing the shaft to achieve rotation. The small round hole is used to install the fixing bolt to ensure stable installation. The main function of the unloading tray is to store the superconducting tape and release it smoothly. During the release process, the tension of the tape can be evenly controlled by controlling the rotation speed and resistance. At the same time, it provides a support point for the superconducting tape to prevent it from sagging or contacting other components, and plays a certain guiding role to ensure that the tape enters the next process in the correct direction.

[0032] The table is installed on the frame of the winding machine to provide support for other components. The magnetic powder brake is associated with the unwinding plate to control the unwinding. The force sensor is connected to the arc transition wheel to measure the tension parameters.

[0033] The arc transition wheel is circular and axially symmetrical in shape, with evenly distributed circular weight-reducing holes and a circular center hole with a connecting structure. The arc transition wheel mainly guides the superconducting tape to be smoothly led out from the unloading tray and enter the winding system in the correct direction, adjusts the tape tension through friction with the tape to ensure winding stability and tape quality, and provides a support point for the tape to prevent it from contacting other components.

[0034] The main function of the magnetic powder brake is to control the state of the internal magnetic powder through the electromagnetic principle, thereby generating a braking torque, which can be used to adjust and control the speed and torque of rotating parts, stabilize the speed and accurately control the torque in the equipment, and ensure the smoothness and reliability of the system operation.

[0035] There is a protruding rod-like structure at one end of the force sensor, which is used to connect or support the components. The force sensor is mainly used to measure the tension or pressure of high-temperature superconducting tapes during production or use. Through the internal strain gauges and other sensing elements, it can convert mechanical stress into electrical signals, thereby achieving accurate monitoring and control of the force conditions of the tape, ensuring the stability of the production process and the quality of the tape.

[0036] The tension control device is composed of a force sensor and a magnetic powder brake. The force sensor can monitor the tension of the strip in real time and feed back the signal to the control system. The tension control device controls the pay-off speed of the strip by adjusting the speed of the pay-off motor according to the feedback signal, so that the tension of the strip is kept within the set range, and the tension can be evenly and stably controlled.

[0037] See also Figure 1 The first pay-off assembly 3, the second pay-off assembly 4 and the third pay-off assembly 5 are each equipped with a power amplifier 8. The power amplifier 8 is composed of multiple electronic components and a heat dissipation structure; its main function is to amplify the input signal, provide sufficient power drive for the parallel winding device, and ensure that the device can stably control the winding operation of the superconducting tape during operation. The power amplifier also has the function of adjusting and stabilizing the output power to meet the winding requirements under different working conditions, and its heat dissipation structure ensures its own stability and reliability during high-power operation.

[0038] See also Figure 1 , a counterweight block 9 is arranged inside the frame 1. The counterweight block 9 is used to ensure the stability of the equipment operation.

[0039] In this embodiment, the control system 6 is a human-machine interface. The human-machine interface is composed of a rectangular panel, on which there are a display screen and operation buttons for user input and system feedback, and the panel works in conjunction with the indicator light 7; the indicator light 7 is a three-color indicator light, the red indicator light is usually used to indicate a fault or warning state, reminding the operator that there is a problem with the equipment and needs to be dealt with; the green indicator light is used to indicate the normal operation of the equipment or the successful operation; the yellow indicator light may be used to indicate the intermediate state of standby, preparation or attention, reminding the operator that the equipment is undergoing a certain operation or is about to change its state.

[0040] In this embodiment, the high temperature superconducting tape multi-wire parallel winding machine is used in conjunction with the winding machine.

[0042] A working principle of a high-temperature superconducting tape multi-wire parallel winding machine includes the following steps:

[0043] S1. Prepare materials: Select appropriate tape according to the specific specifications of the winding task, check the quality of the tape, and ensure that there are no obvious flaws, damage or oxidation on its surface; install the high-temperature superconducting tape on the unwinding tray of each pay-off assembly; during the installation process, pay attention to the starting end of the tape should be smoothly led out of the unwinding tray and pass through the respective arc transition wheels; the tape should be firmly installed on the unwinding tray to prevent it from loosening or slipping during the winding process;

[0044] S2. Setting parameters: Set the basic parameters of winding through the human-computer interaction interface, including the number of winding turns, winding speed and tension parameters; the setting of winding speed should take into account the material, width, thickness of the strip and the performance of the equipment. The tension value should be initially set according to the specifications of the strip and previous experience data, and fine-tuned according to the actual situation during the winding process;

[0045] S3. Start the equipment: After completing the parameter setting, first turn on the main power of the equipment to ensure that all electrical components can be powered normally, and then start the device and the winding machine in sequence; after the equipment is started, pay close attention to the unwinding of the strip to ensure that the strip can be unwinded smoothly from the unwinding disk, and observe the rotation of the winding machine to confirm that the winding speed meets the set value; during the winding process, continuously monitor the tension of the strip; use the control system to check in real time whether the tension of the strip is stable within the set range; if the tension fluctuates, such as a sudden increase or decrease in tension, it needs to be adjusted in time; if the tension fluctuates within a small range, the built-in tension program of the winding machine can be used to adjust the tension back to the set value; if the tension changes drastically, it is necessary to check whether the unwinding speed and the winding speed are coordinated with the winding speed, or check whether other devices have malfunctions to protect the wound coils and remaining strips;

[0046] S4.

[0047] In summary, the present invention can realize the automatic winding of multiple high-temperature superconducting tapes. Through the coordinated work between various systems, the operations of paying out, arranging and winding multiple tapes can be automatically completed, effectively improving the winding efficiency. The tension control device in the pay-out system is a key part. The force sensor monitors the tension of the tape in real time and feeds back the signal. The tension control device adjusts the pay-out speed according to the feedback to ensure that the tension of the tape is uniform and stable during the winding process. This is crucial to ensure the quality of high-temperature superconducting tapes, because superconducting tapes are more sensitive to tension changes, and uneven tension may cause the performance of the tape to deteriorate or be damaged.
