It is worth mentioning that the pay-off device 2, the tensioning device 3 and the guiding device 4 can be manufactured using the relevant technologies of the existing fully automatic winding machine, and its specific structure is not repeated here. A clamping device 6 is installed on one side of the winding shaft 5, and the clamping device 6 can clamp or cut the wire. A first electric push rod 9 is installed at the bottom of the clamping device 6. The first electric push rod 9 controlled by the PLC drives the clamping device 6 to rise and fall. After the product winding is completed, the first electric push rod 9 drives the clamping device 6 to rise and cut the wire. At this time, the product can be removed. Similarly, the clamping device 6 rises to clamp the end of the wire and descends. After replacing the new product, the guide device 4 moves horizontally front, back, left, and right under the control of a preset program, and the wire passing through the guide device is wound around the product. Then the clamping device 6 releases the wire head and descends to reset. An automatic material collecting and unloading device 7 is installed on the machine body 1. The automatic material collecting and unloading device 7 includes a support plate 10. A track 11 is installed on the top of the support plate 10. A mounting groove 12 is slidably installed on the track 11. The mounting groove 12 can move along the track 11, thereby realizing that the mounting groove 12 is close to the winding shaft 5 or away from the winding shaft 5. A second electric push rod 13 is installed in the mounting groove 12. A plurality of product racks 14 are evenly installed on the output shaft of the second electric push rod 13.

When in use, firstly, the product rack 14 is filled with the winding rack 18 to be processed, and the fourth electric push rod 16 is automatically controlled by the PLC to start, pushing up the product rack 14, so that the center of the center hole 29 of the winding rack 18 is at the same height as the center axis surface of the winding shaft 5, and then the PLC automatically controls the second electric push rod 13 to start, pushing the product rack 14 to move left and right, so that the center of the center hole 29 of the winding rack 18 is aligned with the center of the winding shaft 5, and then the PLC automatically controls the third electric push rod 15 to start, driving the winding rack 18 to gradually approach the winding shaft 5 until the winding shaft 5 is plugged into the winding rack 18, and the fourth electric push rod 16 is started to lower the product rack 14, the winding rack 18 is separated from the product rack 14, and the product rack 14 retreats and returns to Initial position, then the winding frame 18 can be started. After the winding is completed, the product rack 14 is first moved to the bottom of the wound winding frame 18, and then raised to insert the winding frame 18 into the vacant position on the product rack 14. The product rack 14 is translated along the axial direction of the winding shaft 5 to remove the winding frame 18. Then the second electric push rod 13 is started to move the product rack 14 left and right. The unprocessed winding frame 18 on the product rack 14 is aligned with the winding shaft 5, and the winding frame 18 is connected to the winding shaft 5 through the third electric push rod 15. The following process refers to the previous winding frame 18 processing process, which will not be repeated here.

In the process of aligning the center hole 29 with the mounting tube 22 and sleeve the winding frame 18 on the mounting tube 22, the elastic component will be squeezed and deformed, so that the friction between the mounting tube 22 and the winding frame 18 is increased, so that the winding frame 18 is more stable when rotating and is not easy to slip. In addition, when it is necessary to replace the product line, it is only necessary to unscrew the nut and replace the mounting tube 22 corresponding to the product, so that the product line can be easily replaced.

In fact, it only needs to protrude 1-2mm, which will not affect the mounting tube 22 passing through the center hole 29. When in use, the inner wall of the center hole 29 is sleeved on the mounting tube 22, so that the top block 24 moves into the mounting cavity 23, thereby compressing the spring 25, thereby increasing the connection strength between the mounting tube 22 and the winding frame 18 through the compressed spring 25.

After the winding is completed, the winding shaft 5 stops rotating, and the product rack 14 first moves to the bottom of the winding frame 18 that has been wound, and then rises to insert the winding frame 18 into the vacant position on the product rack 14.
