In the arc wind tunnel test process, in order to check the heat resistance of the experimental material, a temperature sensor needs to be arranged on a model to obtain effective temperature and heat flow test data. The most common of these temperature sensors are thermocouples of relatively small diameter, typically less than 0.3mm in diameter. The thermocouples of each model are double-wire, and the lengths of the thermocouples needed in practical experiments are different, so that the winding of the thermocouples into finished coils is a practical operation which is frequently carried out in the stage of experiment temperature measurement preparation. Therefore, in the arc wind tunnel experiment, the preparation work of the experiment of making the thermocouple double wire with the extremely small diameter into the finished coil with a certain length is simplified, and the method has important significance in the arc wind tunnel experiment.
In the existing winding method, the thermocouples of the two bobbins are firstly released and gathered, and then the finished wire coil with the required length is wound.

Not only is the tedious operation of the work of the tester increased, but also the waste of expensive thermocouples is caused easily, so that the test progress is influenced, and the test cost is increased.
