a copper wire coil is arranged on a coil holder, a copper wire sequentially passes through a copper wire tension mechanism, a paint stripping mechanism, a wire guide mechanism, a wire drawing device and a wire outlet guide block, when the copper wire is stripped, two wire pressing devices press the front part and the rear part of a part of the copper wire to be stripped, then the laser paint stripping device strips paint on the surface of the copper wire, then a wire twisting frame rotary driving device drives a wire twisting frame to rotate, so that the copper wire is twisted to enable the side surface of the copper wire to face upwards, then the laser paint stripping device strips paint on the side surface of the copper wire, when the copper wire is wound, a Z-axis lifting driving device drives a winding shaft to descend to the top of a wire blocking block, a wire clamping rod, the lower end of a lifting mandrel, the bottom of a sleeve shaft and a wire guide groove of the wire blocking block form a threading channel for one end of the copper wire to insert and pass through, then the wire drawing device pulls the copper wire to enable one end of the copper wire to pass through the threading channel, the lower ends of the wire clamping rod and the lifting mandrel are matched to clamp a copper wire, then a winding shaft rotation driving device drives the winding shaft to rotate, a Z-axis lifting driving device drives the winding shaft to ascend while the winding shaft rotates, so that the copper wire is wound on the lower end of the lifting mandrel, a hot air blowing mechanism can blow hot air to a coil to enable the coil to be in a hot fixing type, after winding is completed, a wire cutting mechanism cuts off the copper wire, then an X-axis translation driving device and a Y-axis translation driving device drive a rotating shaft to move above a framework, the Z-axis lifting driving device drives the winding shaft to descend, meanwhile, a lifting block drives the lifting mandrel to ascend relative to the winding shaft, so that the lower end of the lifting mandrel withdraws from a central hole of the coil, meanwhile, a sleeve shaft pushes the coil downwards, the framework is sleeved on the coil, and therefore, winding of the copper wire and installation of the coil are completed;

the rotary workpiece transfer mechanism sequentially drives a workpiece to move to a pin cutting station, a bending upper punching station, a bending side punching station and a blanking station, when the workpiece is cut, an upper cutter and a lower cutter are matched to cut short pins of a coil, when the workpiece is bent by an upper punch, the upper die is lowered to bend the pins of the coil into a vertical shape, when the workpiece is bent by the side punching, a flat-pushing punch punches the pins of the coil from the side surface to enable the pins of the coil to be bent upwards and lean against the bottom of the framework, a jacking punch ascends and punches the tail ends of the pins of the coil from the lower part to enable the tail ends of the pins of the coil to be bent upwards and lean against the side surface of the framework, when the workpiece is blanked, a pulling device positioned at the blanking station pulls open a clamping block, and a blanking mechanism takes out a finished product for blanking.

In conclusion, the automatic copper wire stripping device is simple and novel in structure and reasonable in design, can realize a series of automatic operations of automatic copper wire stripping, automatic winding, automatic coil skeleton assembly, automatic coil pin cutting, automatic coil pin bending and the like, is high in automation degree, replaces manual operation, greatly improves production efficiency, can guarantee production quality, and can meet the large-scale production requirements of enterprises.
