[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-2 , relying on the servo electronic traverse system, including server 2 and monitoring center 1, monitoring center 1 includes monitoring device 1 3, monitoring device 2 3 and monitoring device 3 3, monitoring center 1 is provided with server 2, and server 2 is connected to industrial control display screen 4 through Internet or 4G network. Industrial control display screen 4 is connected to RS-485 serial port on servo drive controller 7 through RS-485 wiring, servo drive controller 7 is provided with CN1-I / O input interface and CN1-I / O output interface respectively, servo drive controller 7 is connected to spindle encoder 5 through CN1-I / O input interface, and servo drive controller 7 is connected to host controller 6 through CN1-I / O output interface. Servo motor 8 is connected to servo drive controller 7, encoder 9 is provided on servo motor 8, and encoder 9 is reconnected to servo drive controller 7.

[0021] The spindle encoder 5 is installed on the machine spindle through a mechanical device, and the pulse signal from the spindle encoder 5 is transmitted to the servo drive controller 7 through the servo drive CN1-I / O port, and the servo drive controller 7 obtains the pulse signal and converts the signal into a 0-360° angle signal through internal calculation processing. After analyzing the signal transmitted from the spindle encoder 5, the servo drive controller 7 can control the servo motor 8 to work.

[0022] Among them, after the servo drive controller 7 receives and calculates the pulse signal sent by the spindle, it combines the pulse signal with the pre-input mechanical parameters and process parameters and inputs it into the servo motor 8. By combining and analyzing the pulse signal sent by the spindle with the pre-input mechanical parameters and process parameters, the drive data can be customized according to different equipment. After the servo driver calculates the spindle pulse signal, it calculates the required stroke and direction of the servo motor 8 in combination with the mechanical parameters and process parameters input by the host computer to control the servo motor 8 to make corresponding reciprocating movements.

[0023] The servo drive controller 7 is provided with a UVWPE interface, a power line is connected to the UVWPE interface, and the other end of the power line is connected to the servo motor 8. The servo motor 8 can be controlled to work through the power line connected to the UVWPE interface.

[0024] Among them, the encoder 9 is fixedly arranged at the rear of the servo motor 8, and the encoder 9 is an absolute encoder, and the data in the encoder 9 is transmitted to the servo drive controller 7. When the servo motor 8 is in motion, the absolute encoder 9 at the rear of the servo motor 8 feeds back the real-time position of the motor to the servo drive, and the servo drive compares the target position and the actual position of the servo motor 8 and makes corresponding corrections to achieve precise position control. When the device is powered off, the position state of the servo motor 8 at the time of power failure will be recorded. After powering on again, the servo drive can automatically restore the servo motor 8 to the state at the time of power failure.

[0025] The servo drive controller 7 is provided with an industrial control display screen 4 that can work independently, and the mechanical parameters and process parameters are input into the servo drive controller 7 through the industrial control display screen 4. By using the industrial control display screen 4 as the host computer of the servo drive controller 7, the mechanical parameters (number of needle plates, pitch, etc.) and the lateral process parameters (number of flower cakes, process points, etc.) can be written into the servo drive controller 7, and the servo drive controller 7 will save these parameters without writing them every time, and after the data is written into the servo drive controller 7, it can work independently without the host computer.

[0026] When the servo drive controller 7 fails, its fault signal is transmitted to the host controller 6 through the CN1-I / O output interface. When the host controller 6 receives the fault signal from the servo drive controller 7, the servo motor 8 stops. The servo drive I / O will send an alarm signal when the following situations occur: the servo drive fails (overvoltage, overcurrent, overload, etc.), the actual position of the servo motor 8 deviates too much from the target position, or the servo motor 8 fails.

[0027] Among them, the signal transmitted by the spindle encoder 5 has the highest priority, the signal calculated by the servo drive controller 7 for the spindle encoder 5 has the second highest priority, the signal transmitted by the servo motor 8 encoder has the third highest priority, and the input of the industrial control display screen 4 has the lowest priority.

[0028] In this embodiment, when the user uses this device, he needs to first write the relevant parameters (number of needle plates, number of flower cakes, action angle, transverse movement process, etc.) into the servo drive controller 7 through the host computer. The servo drive controller 7 will automatically plan the action process of the servo motor 8 based on these data.

[0029] When in use, the spindle encoder 5 sends out a pulse signal, and the servo drive controller 7 processes the pulse signal to obtain a spindle angle signal. When the spindle angle reaches the needle back action angle or the needle front action angle, the servo drive controller 7 controls the servo motor 8 to make corresponding actions according to the saved transverse process. And through the setting of monitoring device 1, monitoring device 2 and monitoring device 3 arranged on the equipment, the position of the servo motor 8 can be monitored in real time when the servo drive controller 7 is working, and the position can be compared with the target position. When the deviation is too large, the action will be stopped and an alarm signal will be issued.

[0030] Furthermore, the system has a monitoring center 1 and a monitoring terminal industrial control display screen 4. The monitoring center 1 and the industrial control display screen 4 are connected via the Internet or a 4G network to achieve data interaction and simple remote operation.

[0031] The industrial control display screen 4 and the servo driver are connected via the RS485 serial port to write and read data. The spindle encoder 5 collects the spindle signal and transmits it to the servo drive controller 7. After obtaining the spindle signal, the servo drive controller 7 controls the action of the servo motor 8 according to the input process parameters, etc. The servo motor 8 encoder feeds back the position of the servo motor 8 to the servo drive controller 7 in real time, realizing closed-loop control and precise control of the servo motor 8. When the servo drive controller 7 fails, it sends an alarm signal to the host controller 6 through the CN1-I / O signal to stop the host.

[0032] In the present invention, various process parameters can be written into the servo drive controller 7 through the industrial control display screen 4, the spindle signal can be transmitted to the servo drive controller 7 through the spindle encoder 5, and the servo drive controller 7 mixes the spindle encoder 5 data and the written process parameters, and finally controls the servo motor 8 through this parameter to complete the corresponding command action. This can not only ensure the safety of machine operation, but also achieve rapid process. Moreover, the peripheral control circuit is simplified, and the possibility of control circuit failure is reduced. Moreover, the necessary control units such as PLC and motion controller in the past are removed, which greatly reduces the production cost. The system is also integrated into the servo drive, which can be used in combination at will, can meet most requirements, and avoids repeated modification and writing of the control program. In addition, the system can realize remote data monitoring and operation, which is convenient for managers to grasp the operation of the machine in real time, and also convenient for technical support and troubleshooting of technicians, greatly reducing labor costs.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
