Multi-axis Control: Precision winding machines may contain multiple independently controlled axes for winding multiple coils at the same time or winding complex coil structures.

Tension Control: The tension of the wire during the winding process needs to be accurately controlled to ensure the tightness and uniformity of the coil and avoid affecting its electrical performance.

Programmability: Precision winding machines usually allow operators to adjust winding parameters according to different coil design requirements.

Quality Inspection: After winding is completed, the coil will undergo a series of quality inspections, including electrical performance testing and physical size inspection, to ensure that it meets the standards for precision winding.

Safe Operation: Precision winding machine designs usually include safety features, such as emergency stop buttons, safety door interlocks, and so on, to ensure the safety of operators.

Easy Maintenance: The design of the precision winding machine focuses on the convenience of maintenance to reduce downtime and improve production efficiency.

Wide Range of Applications: Precision winding technology is suitable for electronic and electrical product manufacturing of all sizes, from small smart electronic equipment to large industrial transformers.


2. The Technical Principles of Precision Winding

Precision Wiring: Precision winding technology requires that the number of turns and feed amount of each layer of the coil can be accurately set to meet the requirements of high-density wiring. It is usually suitable for coils with thicker wire diameters and fewer turns.

Electronic Cam Control: The inner winding machine uses electronic cams to control the movement of the three axes of the upper and lower axes, indexing axes, and wire arrangement axes to achieve precise winding movements.

Linear Interpolation: During the winding process, the positioning and synchronous movement of each axis can be accurately controlled through the linear interpolation algorithm.

Foot-binding Process: A specific algorithm is used to realize the foot-binding action of the winding machine during the winding process, which usually involves the arc motion of two axes and linear positioning of the other axis.

Cylinder Control: The swing rod flipping, stator clamping, wire trimming, and other actions required during the winding process can be realized through the cylinder control algorithm, which increases the flexibility of the process.

Stop Angle Setting: The winding command can set multiple stop angles to facilitate subsequent process operations after the winding is completed.

Program Management and Editing: Precision winding machine users can edit and store winding programs as needed to adapt to different process requirements.

High Speed and responsiveness: The precision winding machine can operate at high speed, ensuring the stability and control accuracy of the winding machine during operation.

Performance Stability: The use of high-performance controllers and drivers ensures the stability and control accuracy of the winding machine during operation.
