How does computer controlled sewing machine operate?

Now I will talk more about the computer controlled sewing machine. It can complete the functions that traditional sewing machine can not complete. Computer controlled sewing machine has more functions. Such as, automatic cutting, automatic dialing, automatic counting and so on. Advanced computer controlled sewing machine can change that accordance with conditions in the sewing process . It has a high degree of automation and can greatly reduce the operation of workers.  

People have begun to understand more and more the computer controlled sewing machine deeply. Its performances such as needle cloth, thread pick-up, thread hooking and feeding still use the original mechanical mechanism, while the control aspect adopts the electronic or micro-computer system. The general distinction between electronic and micro-computer systems is that control systems with programming and CPU processing are called micro-computer control or computer control systems.

1. Composition of Electronic Control System

Control system is the key part of sewing machine with electrically controlled device. It is generally composed of control body, control object and sensing parts, including control box (controller, driver), motor and electromagnet, sensor and some auxiliary components. The cooperation and linkage between these parts and the computer controlled parts of sewing machine have contributed to the automatic operation of sewing machine. It can enhance the automation ability of machinery. The control part of the electronic control system mainly controls the driving operation of the motor and electromagnet.

First, look at the controller. Its function is to control the sewing machine to complete different stitches. Its function varies with the type of sewing machine. It can be divided into two categories: one is to control the movement of single motor, i.e. the main drive motor, and the other is to complete other auxiliary functions by means of electromagnets, such as cutting and loosening thread. The corresponding sewing machine has single needle, double needle flat sewing machine, sewing machine and bandage machine; the other is to control the coordination of multiple motors. Adjust movement, such as nailing machine, keyhole machine, pattern machine, as well as bending sewing machine to control the swing of needle rod.

Driver is the core of electronic control system. Its hardware consists of power electronic devices and integrated circuits. It transforms the control signal into the driving signal of the actuator and plays a bridge role. The main task of the driver is to receive the signal from the main control box, then process the signal and transfer it to the motor and the inductor related to the motor, and feedback the motor to the main control box.

The software of the driver depends on different kinds of motors. That is similar to the controller, the hardware of the driver is portable, and different kinds of motors with the same power can be used simultaneously.

2. Motor Characteristics in Electronic Control System

Servo motor is an engine that controls the operation of mechanical components in the servo system. It is an indirect transmission device of auxiliary motor. It can accurately control speed, position and accuracy.
