[0042] The utility model discloses still a kind of stator winding machine, including frame and the winding device of mounting in the inboard of the frame, adopt any one of the above-mentioned winding tension mechanism.Winding device is prior art, here no longer repeat.

[0043] First, the tensioning fixed plate is firmly installed on the winding device side of the stator winding machine, ensuring that its installation position is accurate and that the relative position with the winding device meets the design requirements. Next, the shaft of the first driving source is rotatably inserted into the corresponding installation hole on the tensioning fixed plate, and the resistance wheel and the thin brake are installed, ensuring that the resistance wheel can rotate freely and is firmly connected with the shaft, and the thin brake is installed in place and can work normally. Then, the detection assembly is installed. The detection swing seat is installed at a swingable position on the tensioning fixed plate, ensuring that it swings flexibly. The fishing rod element and the fixed spring shaft are inserted into the detection swing seat at the designed angle, and then the adjusting seat is installed on the fixed spring shaft. After adjusting the position with the adjusting screw, the spring is installed, so that the adjusting seat is connected with the tensioning fixed plate through the spring. The detection sheet is detachably installed on the detection swing seat and can normally swing on the U-shaped detection seat (K-type sensor). Finally, the auxiliary guide wheel is installed.

[0044] After installation is completed, the winding tensioning mechanism needs to be debugged. First, start the winding device of the stator winding machine and let the winding start running. Observe the winding on the first driving source and the auxiliary guide wheel, check whether there is a phenomenon of winding jamming or disengagement. If there is a problem, the installation position and rotation flexibility of the guide wheel need to be checked and adjusted. Next, the detection assembly is debugged. By rotating the adjusting screw on the adjusting seat, the pre-tightening force of the spring is adjusted, and the sensitivity of the detection assembly is changed. During winding, observe the swing of the detection sheet in the U-shaped detection seat (K-type sensor), check whether the detection assembly can accurately detect the change and transmit the signal to the first driving source according to the change of the winding tension. The accuracy of the detection assembly can be tested and adjusted by artificially changing the tension of the winding to simulate the actual working condition. At the same time, the thin brake and the resistance wheel of the first driving source are debugged. Check whether the braking effect of the thin brake meets the requirements, and adjust its parameters to change the resistance of the shaft. For the resistance wheel, check the winding in the wire drawing groove to ensure that the sealing ring can provide appropriate friction force so that the winding will not slide on the resistance wheel.

[0045] After the debugging of the winding tensioning mechanism is completed, the stator is installed on the corresponding position of the stator winding machine, and the starting end of the winding is fixed on the stator.

The winding is guided by the auxiliary guide wheel and gradually wound on the resistance wheel of the first driving source. The tension control during winding, when the winding tension is normal during winding, the detection assembly remains in the initial state, and the first driving source rotates at a normal speed to push the winding. When the winding tension increases, the winding will push the detection piece, and the detection swing seat will swing clockwise. After the U-shaped detection seat (K-type sensor) detects the swing of the detection piece, it transmits a signal to the control system, and the control system controls the first driving source to rotate faster. After the rotation speed of the first driving source increases, the winding supply speed increases, the winding tension decreases, and the detection assembly returns to the original state under the action of the spring, so as to realize the automatic adjustment of the winding tension. Conversely, when the winding tension decreases, the detection assembly swings counterclockwise under the action of the spring (if there is such detection and control logic), the control system controls the first driving source to rotate slower, reduces the winding supply speed, and increases the winding tension, and returns to the balance state again. When the stator winding is completed, the stator winding machine is turned off, and the end of the winding is fixed on the stator. Then, the stator is taken off from the winding machine, and the stator winding operation is completed.
