As one of the important equipment for manufacturing motors, the six-station high-speed inner winding machine is widely used in electric fans, range hoods, purifiers, automobiles and other occupations. At present, there are single station, double station, four station and six station winding machine types, and the six-station inner winding machine launched by Xinjie can reach 1200 times/in at the earliest.
The winding machine profession has been carried out for more than ten years, and the difference in equipment performance is not in the mechanical structure, but in the electrical control system. The traditional pulse control plan can no longer meet the requirements of the high-speed inner winding machine, and the bus type motion controller is used to cooperate with the servo system, which has greatly improved the speed and control accuracy, and greatly improved the winding power.
Process principle
1. Winding
The electronic cam upper and lower shaft Z and the rotary shaft are used to carry out cam matching winding;
2. Positioning
The full closed-loop pulse positioning algorithm is used for precise positioning, or the output action of the cylinder is used to support the selection of relative form and absolute form;
3. Foot binding
X-axis, Y-axis, Z-axis three-axis linkage spiral rising interpolation, high control accuracy;
4 indexes
During the commissioning phase, the axis of rotation can be individually rotated.
5 Pause
In the winding process, the machine is paused and the winding is continued;
6. Reset
After the winding is completed, the reset command is used to quickly reset and improve the winding power.
Manipulation plan
According to the high-speed, precise and efficient machining characteristics of the internal winding machine and the rapid career development trend, Xinjie has launched a stator internal winding machine system solution plan with DS5C series EtherCAT bus servo as the drive center and high-performance customized motor as the skeleton.
XG2 series high-equipment medium-sized PLC, TG series 10-inch Ethernet touch screen, DS5C series support EtherCAT bus function servo drive, rotary axis (A, B, C, W, U, V axis) + upper and lower axis (Z1, Z2 axis) use multi-turn absolute encoder, upper and lower axis with brake motor, improve control accuracy, maintain mechanical structure.
Center Strengths
1 custom electronic cam
In the process of winding and arranging, the function of the electronic cam is used, and the rotation axis, the upper and lower axes and the X-axis are bound together with the spindle to ensure that the wires are arranged together in the process of high-speed winding, which improves the echo of the winding, and the curve is soft and over-smooth, making the cable more beautiful and neat without crossing.
2. Full closed-loop pulse positioning algorithm
The motor encoder feeds back the azimuth to the PLC, and the PLC performs high-speed operation through the full closed-loop functional block, gives the target speed to the servo, and controls the servo to carry out full closed-loop positioning, and improves the positioning accuracy together with the satisfaction of high-speed positioning.
3. Spiral rising interpolation and foot wrapping
At the beginning and end of winding, the spiral interpolation function is used, and the three-axis linkage is quickly positioned to do the ascending circle drawing action, which can fix the enameled wire at the hanging wire more quickly and accurately.
4. Open programming
The touch screen uses open programming, and the operator can freely increase the action instructions, which greatly improves the programming power and is simple and convenient to operate.
5. Humanized operation planning
Increase the function of process pause and reset, no need for manual jogging, improve power and speed; Increase the function of hand-cranked pulse, which is convenient for manual debugging.

How to properly ground the PLC - Xinjie PLC
The grounding policy is nothing more than to avoid disturbance for safety, and the policy of grounding to PLC must not be attached to the disturbance at the power supply and input and output terminals, so the accurate grounding system is one of the primary methods for the PLC control system to resist electromagnetic disturbance. There are floating and direct grounding formations.
