[0107] In one embodiment of the present invention, a second proximity switch 705 is provided on the lower edge of the turntable 701 , and the second proximity switch 705 is used for detecting the rotation angle of the turntable 701 .

[0108] In the embodiment of the present invention, the second proximity switch 705 is used to detect the rotation angle of the turntable 701, so as to realize the positioning of the winding assembly 600. Correspondingly, several reflection points can be set on the hollow rotating platform for the reflection of the transmitted signal. , so as to realize the detection. In the embodiment of the present invention, taking the second proximity switch 705 as an example, the proximity switch includes a proximity switch sensing block 702 , a limit block 703 for protecting the proximity switch, and a proximity switch sensing piece 704 .

[0109] In one embodiment of the present invention, four outer corners of the top surface of the second bottom plate 709 of the switching assembly 700 are provided with support columns for installation and connection of the device.

[0110] In the embodiment of the present invention, the support column can be used for the connection of the housing, and can also be used for the installation and fixation of the device, etc. This is an optional specific usage mode, which is not specifically limited in the embodiment of the present invention. The support columns include a first support column 706 .

[0111] In one embodiment of the present invention, the guiding assembly 900 includes a lifting table 901 and a lifting mechanism;

[0112] The lifting platform 901 is provided with an arc-shaped gap on one side edge facing the winding assembly 600, and the side edge away from the winding assembly 600 is rolled down;

[0113] A strut 909 is connected under the lifting platform 901, and the strut 909 passes through the screw motor fixing plate 908, and the bottom of the strut 909 is connected with the supporting plate 905; the screw motor fixing plate 908 is provided with a screw motor 904, and the screw motor The output shaft of 904 is connected with a screw mandrel, which is threadedly connected with the supporting plate 905, and the lifting table 901 is driven to move up and down by the screw mandrel motor 904.

[0114] In the embodiment of the present invention, when winding the wire, one end of the charging wire is clipped into the clamping member 620, and the charging wire is placed on the lifting platform 901. During the winding process, the lifting platform 901 moves upward at a constant speed to guide the charging wire from bottom to bottom. Winding on the arc-shaped tile 601 to form a single-layer coil. Optionally, the closer the distance between the arc-shaped notch of the lifting platform 901 and the arc-shaped tile 601 is, the more reliable the guiding effect is; the specific distance is optional, and is not specifically limited in this embodiment of the present invention.

[0115] In the embodiment of the present invention, the screw motor fixing plate 908 is connected to the support rod 909 through a linear bearing 903; the third proximity switch 907 is arranged under the screw motor fixing plate, and the third proximity switch is arranged on the proximity switch mounting piece 906 on.

[0116] The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
