DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Please refer to Figure 1 - Figure 3 The utility model provides a technical scheme: a double-motor synchronous rotation winding mechanism, comprising the following steps:

[0021] In the electronic device production workshop, the staff will be wound around the end of the wire fixed on the reel 1005, and use the pressure plate 1006 to tighten, to ensure that the wire will not fall off. According to the coil specifications, by controlling the system to set the speed of a pair of servo motor 1007, the direction of rotation and the number of turns and other parameters, while adjusting the operation parameters of brushless motor, to determine the lifting speed and stroke of the vertical plate 1003.

[0022] Turn on the electric telescopic rod 2002, according to the initial position of the wire and the required tension, adjust the telescopic length of the electric telescopic rod 2002. The telescopic end of the electric telescopic rod 2002 pushes the connecting frame 2003, so that the turntable 2004 installed at the bottom of the connecting frame 2003 moves horizontally. The turntable 2004 pushes the wire to adjust it to the appropriate position and give it a certain tension. Two pairs of limit rods 1002 limit the wire to ensure that the wire remains straight in the horizontal direction, preparing for winding.

[0023] Start the servo motor 1007, two servo motors 1007 operate synchronously under the monitoring of the encoder and the adjustment of the control system, drive the reel 1005 to rotate at high speed. At the same time, the brushless motor starts to drive the threaded rod to rotate, and the threaded rod drives the sliding plate 1009 to slide upward in the sliding groove 1010, and then makes the vertical plate 1003, the fixed plate 1004 and the reel 1005 slowly rise. In this process, the wire is uniformly and tightly wound on the reel 1005 under the action of rotation and upward movement of the reel 1005. Because of the good synchronization of the servo motor 1007, the tension of the wire during winding is stable, and there is no loose or broken wire. During winding, the tension of the two wires is measured by the tension measuring instrument, and the tension is adjusted in real time by the adjusting mechanism.

[0024] When the winding reaches the predetermined number of turns, the servo motor 1007 and the brushless motor stop working, and the cutter cuts off the wire. The staff closes the electric telescopic rod 2002, takes off the reel 1005 with the wound coil from the equipment, and carries out subsequent processing, such as insulation treatment, detection, etc. During the whole winding process, the heat dissipation groove 1008 continuously dissipates the heat generated by the brushless motor and other devices, ensuring the stable operation of the equipment.

[0025] Specifically, the working principle of the double-motor synchronous rotating winding mechanism is as follows: when in use, the winding mechanism 100 is first started. A pair of servo motors 1007 are used as the first driving element and are started. The internal encoder can monitor the rotation speed and position in real time, and the control system can control the highly synchronous operation. The output end of the servo motor 1007 drives the reel 1005 to rotate at high speed, and the wire is wound on the reel 1005. At the same time, the brushless motor in the workbench 1001 operates, and the output end drives the threaded rod to rotate. The sliding plate 1009 drives the vertical plate 1003 to rise with the rotation of the threaded rod. The vertical plate 1003 drives the fixed plate 1004 and the reel 1005 to rise, so that the wire is arranged in order on the reel 1005, and multi-layer winding is realized. The adjusting mechanism 200 is used to accurately control the position and tension of the wire. During the winding process, the tension of the two wires is measured by the tension measuring instrument, and the tension is adjusted in real time by the adjusting mechanism, and the electric telescopic rod 2002 is started. The telescopic end of the electric telescopic rod 2002 pushes the connecting frame 2003, and the connecting frame 2003 drives the turntable 2004 installed on the bottom surface to move horizontally. The turntable 2004 contacts and pushes the wire, changes the position and tension of the wire, and adjusts the uniformity of the subsequent winding. The turntable 2004 has the ability to rotate, so it will not hinder the movement of the wire.
