[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0020] Reference Figure 1 , discloses the structure of a skeleton, the skeleton includes a top plate and a winding post arranged on the lower surface of the top plate, the structure of the top plate is stacked left and right and front and back, and two symmetrical notches are arranged on the top plate, the winding post is used for winding the wire, and the wire head and wire tail can be inserted into the notch.

[0021] Reference Figures 2 to 5 The present invention discloses a winding device of a winding machine, comprising: a frame 100, a winding group 300, a skeleton clamp, a wire fixing head device 400, a wire cutting device 500 and a hot air device 600.

[0022] A driving device 110 is provided on the frame 100 , and a bracket 200 is provided on the output end of the driving device 110 . The driving device 110 is used to drive the bracket 200 to move in the front-back, left-right and up-down directions. The driving device 110 drives the bracket 200 to move in three-dimensional space.

[0023] Reference Figure 5 and Figure 6 The winding assembly 300 includes a rotating shaft 310, a wire outlet needle 320 and a first thread end clamp 330. The rotating shaft 310 is rotatably arranged on the bracket 200. The wire outlet needle 320 is arranged on the rotating shaft 310. The wire outlet needle 320 is provided with a wire hole for the wire to pass through. The wire hole is eccentrically arranged with the rotation axis of the rotating shaft 310. The first thread end clamp 330 is arranged on the rotating shaft 310 so as to be able to be raised and lowered. The first thread end clamp 330 is used to clamp or release the thread end of the wire. The bracket 200 is provided with a first rotating drive mechanism. The output end of the first rotating drive mechanism is transmission-connected with the rotating shaft 310. The first rotating drive mechanism drives the rotating shaft 310 to rotate on the bracket 200. The rotating shaft 310 realizes self-rotation. The rotating shaft 310 carries the wire outlet needle 320 and the first thread end clamp 330 to rotate. The wire outlet needle 320 and the first thread end clamp 330 both rotate around the rotation axis of the rotating shaft 310.

[0024] The skeleton clamp is arranged below the winding group 300 and is used to clamp the skeleton. The rotating shaft 310 is vertically arranged on the bracket 200, and the rotating shaft 310 has the up-down direction as the rotating axis. The skeleton clamp is a common component on the market. The winding column of the skeleton extends into the opened skeleton clamp, and then the skeleton clamp is closed to clamp the skeleton. The skeleton clamp can be opened again to remove the skeleton from the skeleton clamp.

[0025] Reference Figure 2 and Figure 8The thread end fixing device 400 includes a second thread end clamp 410 that can move in the front-back and up-down directions. The second thread end clamp 410 is close to the winding group 300 and takes over the thread end from the first thread end clamp 330. The second thread end clamp 410 clamps and positions the thread end. The rotating shaft 310 drives the thread outlet needle 320 to rotate so that the wire is wound around the frame. The first thread end clamp 330 takes back the thread end from the second thread end clamp 410. The first thread end clamp 330 moves up and releases the thread end so that the thread end faces upward, and the first thread end clamp 330 pulls up the wire between the thread outlet needle 320 and the frame.

[0026] Reference Figure 2 and Fig. 9 The wire cutting device 500 includes a cutter 510 that can move in the front-back and up-down directions. The cutter 510 cuts the wire between the frame and the first wire end clamp 330 so that an upward wire tail is formed on the frame.

[0027] The hot air device 600 is used to deliver hot air to the wire on the frame so that the wire is shaped on the frame. The wire is a hot-melt wire. The wire can be softened by heating the wire with hot air or other means, so that it is easy to shape the wire. After shaping, the wire can maintain a good shape, that is, it is fixed. Hot-melt wires are common components on the market.

[0028] It can be understood that the wire fixing head device 400 and the hot air device 600 are both arranged in front of the winding group 300 , and the wire cutting device 500 is arranged behind the winding group 300 .

[0029] When the winding device winds the wire around the skeleton, initially, the wire end of the wire passes through the wire hole from top to bottom and is placed on the first wire end clamp 330. The first wire end clamp 330 clamps the wire end, and the second wire end clamp 410 and the wire cutting device 500 are both away from the winding group 300 and the skeleton clamp. The skeleton is placed on the skeleton clamp. At this time, the skeleton is below the winding group 300; then the second wire end clamp 410 moves in the front-to-back and up-and-down directions so that the second wire end clamp 410 clamps the wire between the outlet needle 320 and the first wire end clamp 330, and the first wire end clamp 330 releases the wire end. At this time, the second wire end clamp 41 0 can complete the positioning of the thread end; then the driving device 110 drives the bracket 200 and the rotating shaft 310 to move in the front-to-back, left-to-right and up-to-down directions, the rotating shaft 310 carries the wire outlet needle 320 to move, the wire outlet needle 320 pulls the wire across the winding column of the frame, and then the rotating shaft 310 rotates, so that the wire outlet needle 320 rotates around the frame, so that multiple turns of wire are wound around the frame, so that a winding is formed on the frame; the rotating shaft 310 moves in the front-to-back, left-to-right and up-to-down directions again, so that the first thread end clamp 330 returns to the initial position, and the first thread end clamp 330 is connected back from the second thread end clamp 410 The first thread end clamp 330 is reset, and then the rotating shaft 310 carries the first thread end clamp 330 to move upward, the first thread end clamp 330 pulls the thread end upward, and then the first thread end clamp 330 releases the thread end so that the thread end faces upward. After the first thread end clamp 330 releases the thread end, the rotating shaft 310 drives the first thread end clamp 330 to rotate so that the first thread end clamp 330 clamps the tail end of the wire, that is, the first thread end clamp 330 is in a state of clamping the wire between the outlet needle 320 and the frame, and then the rotating shaft 310 drives the first thread end clamp 330 to move upward, the first thread end clamp 330 straightens the wire and makes the first thread end clamp 33 0 and the frame gradually stand up; then, the cutter 510 moves in the front-back and up-down directions. When the cutter 510 is in the lower projection area of ​​the wire between the first wire end clamp 330 and the frame, the cutter 510 moves upward from the area between the first wire end clamp 330 and the frame. When the cutter 510 rises to a height close to the first wire end clamp 330, the wire is cut off. The wire is at the port of the area close to the first wire end clamp 330, and the wire between the first wire end clamp 330 and the frame is cut off, so that the wire on the frame forms an upward wire tail, and the wire clamped by the first wire end clamp 330 forms a new wire end. In the process of the winding device winding the wire on the frame, the hot air device 600 delivers hot air to the wire on the frame to shape the wire on the frame.

[0030] It is understandable that the first thread end clamp 330 can clamp the thread end fixedly. When the first thread end clamp 330 clamps the wire between the thread outlet needle 320 and the frame, the clamping force of the first thread end clamp 330 is small, so that the wire can slide on the first thread end clamp 330, and the first thread end clamp 330 plays the role of hooking the wire between the thread outlet needle 320 and the frame, so that the wire between the first thread end clamp 330 and the frame gradually grows and gradually becomes upright.

[0031] Through the cooperation of the winding group 300, the wire fixing head device 400 and the wire cutting device 500, not only the winding of the skeleton can be completed, but also the wire heads and tails of the wires on the skeleton can be made to face upwards, without the need to set up a wire management mechanism, and the structure of the wire cutting device 500 is relatively simple, the structure of the winding device is relatively simple and compact, the winding steps are relatively few and simple, and the winding efficiency can be effectively improved.

[0032] Since the wire outlet needle 320 and the first thread end clamp 330 are both arranged on the rotating shaft 310, when the first thread end clamp 330 clamps and releases the thread end, the wire outlet needle 320 may interfere with the skeleton clamp, the thread head fixing device 400 and the hot air device 600, and when the wire outlet needle 320 rotates around the central axis of the winding group 300, the first thread end clamp 330 may interfere with the skeleton clamp, the thread head fixing device 400 and the hot air device 600, so it is necessary to be able to adjust the height of the first thread end clamp 330 so that the wire outlet needle 320 and the first thread end clamp 330 are staggered in the up and down directions, thereby causing the first thread end clamp 330 to interfere with other components.

[0033] The first thread clamp 330 can be raised and lowered on the rotating shaft 310. The height of the first thread clamp 330 can be changed according to actual conditions, and the relative height between the thread outlet needle 320 and the first thread clamp 330 can be changed. The height of the first thread clamp 330 is adjusted so that the first thread clamp 330 is at a suitable height position to avoid interference between the thread outlet needle 320 and other components when the first thread clamp 330 is working.

[0034] Specifically, when the first thread end clamp 330 clamps the thread end, the first thread end clamp 330 can be lowered to a low position, that is, the wire outlet needle 320 is in a higher position, avoiding interference between the wire outlet needle 320 and the skeleton and the skeleton clamp; when the rotating shaft 310 drives the wire outlet needle 320 to rotate to wind the wire around the skeleton, the first thread end clamp 330 rises to a high position, avoiding interference between the first thread end clamp 330 and the skeleton, the skeleton clamp and the second thread end clamp 410.

[0035] Reference Figures 5 to 7In some embodiments, the winding group 300 also includes a first lifting drive mechanism 350 and a second lifting drive mechanism 340, and the first wire end clamp 330 includes a first elastic member 332, a second elastic member 331, a first clamping arm 333 and a second clamping arm 334.

[0036] The first clamping arm 333 includes a first sliding portion 333a and a first clamping portion 333b provided at the lower end of the first sliding portion 333a, the first sliding portion 333a is slidably provided on the rotating shaft 310 up and down, the second clamping arm 334 includes a second sliding portion 334a and a second clamping portion 334b ​​provided at the lower end of the second sliding portion 334a, the second sliding portion 334a is slidably provided on the first sliding portion 333a up and down, the second clamping portion 334b ​​is located below the first clamping portion 333b, the second elastic member 331 is used to force the second sliding portion 334a to move up, so that the first clamping portion 333b and the second clamping portion 334b ​​clamp the thread end or the wire between the thread outlet needle 320 and the frame, and the output end of the second lifting drive mechanism 340 is used to drive the second sliding portion 334a to move down, so that the first clamping portion 333b and the second clamping portion 334b ​​release the thread end. In the natural state, the second elastic member 331 forces the second sliding portion 334a to move upward, so that the second clamping portion 334b ​​is close to the first clamping portion 333b, and then the second clamping portion 334b ​​and the first clamping portion 333b are kept in a clamping state, and the second clamping portion 334b ​​and the first clamping portion 333b can clamp the thread end or the wire between the outlet needle 320 and the frame. When the second lifting drive mechanism 340 drives the second sliding portion 334a to move downward, the second clamping portion 334b ​​moves downward to move away from the first clamping portion 333b, and the thread end can be released.

[0037] It can be understood that the first thread end clamp 330 is used to position the thread end and does not need to clamp the wire end / conducting wire, so the second elastic member 331 only needs to maintain a moderate elastic force, so that the second clamping portion 334b ​​and the first clamping portion 333b clamp and stabilize the thread end / conducting wire, and enable the wire to pass between the second clamping portion 334b ​​and the first clamping portion 333b, that is, hook up the tail end of the wire.

[0038] The first elastic member 332 is used to force the first sliding portion 333a and the second sliding portion 334a to move upward, and the output end of the first lifting drive mechanism 350 is used to drive the first sliding portion 333a to move downward, so as to achieve the descent and ascent of the first thread clamp 330. In a natural state, the first elastic member 332 forces the first sliding portion 333a to move upward and be in a high position, and the first clamping arm 333 drives the second clamping arm 334 to move upward synchronously, so that the first clamping arm 333 and the second clamping arm 334 are in a high position; and when the first lifting drive mechanism 350 drives the first sliding portion 333a to move downward, the first clamping arm 333 and the second clamping arm 334 move downward synchronously, thereby achieving the adjustment of the height of the first thread clamp 330.

[0040] The first sliding portion 333a is penetrated by a second guide hole, the second sliding portion 334a is penetrated by the second guide hole, the upper end of the second sliding portion 334a extends to the top of the second guide hole and is located above the first sliding portion 333a, the output end of the second lifting drive mechanism 340 is located above the second sliding portion 334a, the lower end of the second sliding portion 334a extends to the bottom of the first sliding portion 333a and is connected to the second clamping portion 334b, the second guide hole serves to guide the sliding direction of the second clamping portion 334b, so that the second clamping arm 334 can slide on the first clamping arm 333, and the output end of the second lifting drive mechanism 340 can be against the upper end of the second sliding portion 334a.

[0041] The axial directions of the first guide hole 311 and the second guide hole are both in the up-down direction. The first sliding portion 333a and the first clamping portion 333b as well as the second sliding portion 334a and the second clamping portion 334b ​​are perpendicular to each other, and the first clamping portion 333b and the second clamping portion 334b ​​are both arranged horizontally.

Two ends of the first guide hole 311 are respectively opened at the lower end surface of the rotating shaft 310 and the lower side wall of the through hole 312. The first sliding portion 333a is penetrated through the first guide hole 311, and the second sliding portion 334a is penetrated through the second guide hole, so that the main structures of the first clamping arm 333 and the second clamping arm 334 are both within the lower projection range of the rotating shaft 310, so that the structure of the winding group 300 is more compact, and the outer side of the rotating shaft 310 has a larger free space, so that multiple winding groups 300 can be arranged side by side.

[0043] The upper end of the second sliding portion 334a is connected to the second pressing portion 334c extending to the outside of the rotating shaft 310.
