[0035] There are two sets of switching limit assemblies 17, both mounted on the base plate 32 and distributed on the front and rear sides of the lower spindle switching device 16, and the two sets of switching limit assemblies 17 are in the same straight line with the lower spindle seat 20. The upper end of the switching limit assembly 17 is coated with urethane foam, which can provide a certain buffering effect.

When the double-station winding device 18 is switched in place, the limit column 24 collides with the switching limit assembly 17 under the action of inertia to slow down the inertia, so as to achieve fast and accurate positioning and extend the life of the equipment. Finally, the coil winding cycle starts and the next station is connected.

[0043] Therefore, the present invention adopts the above-mentioned copper wire voice coil double-station winding device, which can effectively reduce the waiting time of the station and greatly improve the production efficiency of the equipment.
