[0035] The technical solutions of the present application will be further described below in conjunction with the examples and drawings.

[0036] As shown in the drawings, the transformer coil winding device of the embodiment of the present application comprises: Figures 1-4 The base 1 is provided with a wire passing opening 1031 for the coil to pass through along the first direction X;

[0040] The second driving member 4 is installed on the transmission assembly 3, and the power output end of the second driving member 4 is provided with an installation shaft 401 extending in the second direction Y for driving the installation shaft 401 to rotate.

[0041] The guide assembly 5 includes a broken line sensor 501 arranged at the wire passing port 1031 of the base 1 for detecting whether the coil passing through the wire passing port 1031 is broken.

[0042] The control assembly is electrically connected with the first driving member 2, the second driving member 4 and the broken line sensor 501.

[0043] The first direction X is perpendicular to the second direction Y.

[0044] Specifically, the second driving member 4 is an electric motor.

[0045] According to the above technical scheme, the winding roller is installed on the installation shaft 401, the coil is wound on the winding roller after passing through the detection end of the broken line sensor 501 and then passing through the wire passing port 1031, at this time, the first driving member 2 drives the transmission assembly 3 to slide in the second direction Y, the second driving member 4 drives the installation shaft 401 to rotate to drive the winding roller to rotate, and the control assembly controls the sliding speed of the transmission assembly 3 to match the rotating speed of the installation shaft 401, so that the coil can be wound on the winding roller in sequence, when the broken line sensor 501 detects that the coil is broken, the control assembly immediately sends a stop command to the first driving member 2 and the second driving member 4 to pause the equipment operation, preventing the material waste or winding error caused by broken line (the control assembly is not shown in the drawings).

[0046] The broken line sensor 501 is arranged at the wire passing port 1031 and can accurately monitor the state of the coil, and once the broken line is detected, a signal is triggered immediately. After receiving the signal of the broken line sensor 501, the control assembly can stop the operation of the first driving member 2 and the second driving member 4 in real time, avoiding the situation that the material is wasted or the equipment is damaged due to the continuous operation after the coil is broken.

Through the cooperative work of the broken wire sensors 501, the influence of environmental interference on detection accuracy is reduced, and the stability of broken wire monitoring during winding is ensured; the detection cylinder 502 structure is suitable for coils of different diameters and materials, ensuring the detection effect of the coil in various specifications of winding tasks. The circumferentially distributed plurality of broken wire sensors 501 can adapt to the slight deviation or swing of the coil during winding, ensuring that the broken wire can be effectively detected even if the material is not completely in the center position.
