Application of the hottest Kinco servo in winding

The application of Kinco servo in winding machine

the winding machine system is a kind of mechanical equipment with high requirements for speed and precision control, which requires the control system to provide very accurate and smooth linear speed and flexible commutation ability. The system we made is used to wind the voice coil in the headset, so the requirements of the system are higher in all aspects. The whole system is complex, with many control equipment, and requires high coordination between each motor. The system uses two sets of servo motors for control, and each set of servo motors has data exchange, and the data communication also requires strong real-time, that is, the system is required to have the ability of main line communication. In this way, the servo driver is required to have very powerful functions to meet the control requirements. Our servo driver can meet the control requirements of this kind of system. Here are some functional features of our driver:

1. Full digital speed and position control function, and provide position, speed and torque control function

2. Flexible tracking control mode provides high sensitivity tracking effect

3. Programmable digital input and output

4. It can monitor motor short circuit, voltage, temperature, encoder, position tracking and high current faults

5. Parameters can be set through RS232, RS485, PROFIBUS and can communication ports

therefore, our servo driver is fully qualified for this job. The following is a general introduction of this system:

Description: 100W servo is a winding motor, and 200W servo is a winding motor. The above figure shows the winding part cut from the winding machine, which is the main part of the mechanical equipment. Other parts are omitted, so the schematic diagram is simplified. The original servo system is a special operation of Japanese system. At the same time, it has to compete with foreign experimental machines for dynamic control system. It brings two sets of servo through the bus. Although the function is good, the cost is too high

II. Process description

the mechanical equipment is the equipment for winding the voice coil in the headset, and the thinnest metal wire to be wound is 2 wires. After the equipment is started, all cylinders are reset. At this time, the wire arrangement mechanism driven by the guide cylinder moves to the initial position of the wire arrangement through the slide rail platform, and the wire arrangement motor returns to the original point. At the same time, the wire arrangement motor rotates to the starting angle to realize the production based on sales. Thread the wire and lead it on the winding wheel and winding shaft. At this time, the winding motor starts to run continuously, and the winding motor follows the winding. After the number of windings reaches the set value, the winding motor reverses the winding until the number of layers of winding reaches the set value, and the winding and winding servo motor stops

III. process requirements

1: product winding requirements: metal wires should be close to each other. When viewed under the microscope, they should look like a mirror, and the metal wires between each circle should not be overlapped. The edge should be neat, and the position of the starting wire and the cut wire should be on the same edge

2: the system should be automatic, manual step-by-step operation, reset operation, and all cylinders should also be able to operate independently

3: all motor parameters should be set on the touch screen and the corresponding data should be displayed

IV. effective analysis of technical difficulties and key points on the fluctuation of the industrial chain

1: high winding accuracy, tight wire arrangement, no pause in reversing, no rush, neat edges

2: the logic action of the whole system should be strictly coordinated, and any error will affect the accuracy and component damage

3: good product stability and reliable action

v. Kinco solution configuration

the winding motor adopts a three-phase servo ed430 driver with CAN bus +60s-aa-4lg

the wiring motor adopts a two-phase servo ed100 driver with CAN bus +23sn7 (80000 resolution), the HMI adopts mt4300c with 5.7-inch true color display, and the PLC adopts Kinco k406cn. The PLC has a can communication interface, a 232 communication port and a 485 communication port, which is powerful and has strong communication ability, In addition, a remote bus i/o module is used to connect remote IO, reducing the complexity of equipment wiring. Depending on the complexity of the system, more such modules can be added

VI. solution principle provided by Kinco

1: when the winding motor is powered on or reset, the 32 mode is used to return to the origin. The absolute positioning mode is always used in the operation process to ensure that no error is accumulated. All process angles are based on the index signal to ensure accuracy. When winding, the first round of non winding treatment is adopted to ensure that the edge is flat. The winding motor adopts the No.5 mode to return to the original point when it is powered on or reset. The master-slave follow function with good ed servo is always used in the winding process. Follow the winding motor. When reversing in place, directly change the gear ratio to a negative number, so that it does not stop, but rush, and the edge is neat

2: the CAN bus scheme adopted by the PLC control system has fast communication speed, good anti-interference performance, high reliability, rich user parameter settings and easy maintenance

VII. Electrical block diagram of the system

VIII. Conclusion

1. The system can fully meet the requirements of customers for winding accuracy and flatness, but also reduce the comprehensive cost of the system, and can completely replace the previous Japanese control scheme

2. The internal algorithm of the servo automatically calculates its own speed. The system responds in time, follows and controls properly, and there will be no situation near the tower.

the system adopts can bus communication, which enhances the anti-interference of the system
