DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below. Figure 1 and Figure 2 An embodiment of the utility model provides a coil reversing device, comprising a base 100 and two rotating brackets 200 arranged thereon, two sets of rotating drive mechanisms 300, two cantilevers 400, a docking drive mechanism 500 and two sets of pushing mechanisms 600. The two rotating brackets 200 are rotatably arranged on the base 100, and the two sets of rotating drive mechanisms 300 are respectively connected to the two rotating brackets 200, and are used to drive the rotating brackets 200 to rotate relative to the base 100 in a horizontal plane. The two cantilevers 400 are respectively horizontally arranged on the two rotating brackets 200, and the two cantilevers 400 have the same height. A retractable stop pin 430 is provided at the suspended end of each cantilever 400, and a retractable drive mechanism 440 is provided inside the cantilever 400. The stop pin can be extended from the circumference of the cantilever 400 to the outside of the cantilever 400 or retracted into the cantilever 400 under the drive of the retractable drive mechanism 440. The docking drive mechanism 500 is mounted on the base 100 and connected to at least one rotating bracket 200. It is used to drive the two rotating brackets 200 toward or away from each other, docking or undocking the cantilevers 400 on the two rotating brackets 200. Two sets of pusher mechanisms 600 are mounted on each cantilever 400. Each pusher mechanism 600 is located at the end where the cantilever 400 connects to the rotating bracket 200. When the two cantilevers 400 dock, the pusher mechanism 600 pushes the coil from one cantilever 400 onto the other cantilever 400, completing the coil reversal.

[0024] The coil reversing process of the coil reversing device of the embodiment of the present invention is shown in the figure: in the initial state, the directions of the two cantilevers 400 are parallel, and the pole piece coil that needs to be reversed is loaded onto one of the cantilevers 400 manually or through other equipment. After loading is completed, the stop pin 430 on the cantilever 400 extends to prevent the coil from escaping from the cantilever 400 during the turning process of the cantilever 400; after loading is completed, the two rotating brackets 200 are rotated 90 degrees under the drive of the rotating drive mechanism 300, so that the suspended ends of the two cantilevers 400 are opposite to each other, and then the docking drive mechanism 500 drives the two cantilevers 400 to rotate 90 degrees. The two cantilevers 400 approach each other so that the suspended ends of the two cantilevers 400 are docked; after docking, the stop pin 430 on the cantilever 400 retracts, and the pushing mechanism 600 on the cantilever 400 carrying the coil works to push the coil to the other cantilever 400. After the coil is in place, the stop pin 430 on the other cantilever 400 extends, and then, driven by the two rotating drive mechanisms 300, the two cantilevers 400 rotate 90 degrees to restore parallelism, completing the reversal of the coil. The coil can be moved from the cantilever 400 to the handling AGV equipment to be transported to the production line of the next process. The coil reversing device of the embodiment of the utility model can move multiple coils that need to be reversed to the cantilever 400, and complete the reversal of multiple pole piece coils at one time. There is no need for manual handling of the coils during the reversing process, which reduces the risk of the pole pieces being scratched during the reversing process, improves the reversing efficiency of the coils, and reduces the human resource consumption of the coil reversing.
