For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the utility model can be understood according to the specific circumstances.

[0036] In an embodiment of the utility model, as shown in Figures 1-7 A cable 600 winding device is provided, which comprises an external cable feeding mechanism and a tension monitoring mechanism, the tension monitoring mechanism comprises a mounting seat 100, a buffer assembly 200 and a roller assembly 300, the mounting seat 100 is provided with a wire passing hole 500; the buffer assembly 200 is arranged on the mounting seat 100 and located at one end of the wire passing hole 500; the roller assembly 300 is rotatably connected to the end of the buffer assembly 200; wherein the mounting seat 100 is provided with a distance detection unit 400, the output end of the distance detection unit 400 is located at the end of the wire passing hole 500 away from the roller assembly 300, and the distance detection unit 400 is used for detecting the position of the cable 600 rotatably connected to the roller assembly 300.
