What is the working principle of automatic winding machine

The yarn winding machine spindle mechanism assembly is composed of a spindle servo motor, a spindle assembly, and a winding workpiece fixture. Its working principle is that the control system controls the servo motor to drive the spindle assembly to rotate. A workpiece fixture is installed on each spindle to clamp the winding workpiece skeleton and drive it to rotate. Winding. The wire arranging mechanism is composed of wire nozzle, wire arbor, X, Y, Z three-axis winding drive device. The thread nozzle is installed on the spool, and the X, Y, Z three-axis winding drive device is composed of three groups of ball screw mechanisms and a servo motor. The servo motor drives the ball screw mechanism to move under the drive of the control system command, so that it is accurate Control the X, Y, and Z axis movements of the cable spool. The X, Y, Z three-axis winding drive device drives the cable winding shaft to perform three-dimensional movement, and cooperates with the spindle mechanism assembly to drive the coil workpiece skeleton to rotate, and the electromagnetic wire is accurately wound on the coil workpiece skeleton through the wire nozzle to complete the cable winding action.

The high-precision cable arranging system is the key assembly for realizing high-quality and accurate winding of the coil. During the winding process, the circular arc interpolation and linear interpolation of the CNC system are used to make the cable arranging mechanism and the spindle mechanism assembly accurate. Cooperate with the movement to achieve precise cable arrangement. Ensure that the coil winding is evenly and tightly wound, and the turns are closely arranged. Avoid defects such as cones, collapses and protrusions. At the same time, it can correctly complete the movements of head wrapping and tail wrapping. The wire clamp mechanism is composed of a wire clamp assembly, a driving cylinder and other mechanisms. The wire clamp driving cylinder completes the clamping and opening of the wire clamp head, and the up and down, front and rear driving cylinders complete the corresponding movement of the wire clamp assembly. The swing drive cylinder drives the wire clamp assembly to swing through the rack and pinion mechanism.

After the loading and unloading mechanism sends the coil workpiece skeleton to the clamp on the spindle and clamps it, it first performs a head-wound action. The wire clamp cylinder drives the wire clamp to clamp the wire end of the electromagnetic wire and moves it to a suitable position. Traction, under the driving of the X, Y, Z three-axis wire arrangement, the foot binding movement is carried out. The wire clamp mechanism loosens the wire end of the electromagnetic wire, and the wire arrangement mechanism and the spindle mechanism perform winding. At the end of the winding, the tail winding is completed. The electromagnetic wire is pulled down by the wire nozzle to the middle of the wire chuck. The wire clamp assembly closes the wire chuck under the drive of the cylinder. After the thread trimming action is completed, the wire clamp mechanism continues to clamp the electromagnetic wire, waiting for the next workpiece skeleton to be wrapped.

The entire winding process of the wire is repeated continuously without manual participation, which greatly improves production efficiency. In order to make the wound coil tight and suitable, the tightening is full and the consistency of the coil technical index is guaranteed. The electromagnetic wire should be wound with proper tension. The magnetic damping tensioner is the key component of the adjustable tension generated by the winding machine during winding. It uses a magnetic field as a medium to generate a constant resistance torque through magnetic damping to ensure constant tension during the pay-off process, and its tension control is extremely stable . The electromagnetic wire passes through the tension controller and the wire nozzle fixed on the spool mechanism. The high-precision tension controller ensures that the electromagnetic wire can be tightly wound on the workpiece skeleton.
