The control and detection system of Jinan two-component glue machine is the integration of software and hardware, which is the core of the whole system, During dispensing, it is necessary to set the initial parameters of the subsystem, coordinate the work among the subsystems, monitor the working state of the subsystem, and collect, transmit and process the working pressure and temperature data.

双组份打胶机点胶过程持续较短， 一般为几十毫秒到几秒钟的时间， 由于电磁阀为开关控制，因此要提高控制精度，只有缩短采样周期进行实时测量，以及减少电磁阀的动作误差的方法来具体实现。

The dispensing process of two-component dispenser lasts for a short time, generally from tens of milliseconds to a few seconds. Because the solenoid valve is controlled by on-off switch, the only way to improve the control accuracy is to shorten the sampling period for real-time measurement and reduce the action error of the solenoid valve.

具体对控制系统的实现来说，就要求系统定时精度误差能够保证在 ms 级以下。这就对控制系统的实时性提出了很高的要求。因而智能点胶控制系统的核心技术之一就是如何完成这一高实时性的任务。

For the realization of the control system, the timing accuracy error of the system is required to be less than Ms. This puts forward a high demand for the real-time performance of the control system. Therefore, one of the core technologies of intelligent dispensing control system is how to complete this high real-time task.

在生产应用中常用到的驱动方式有：

In the production application, the commonly used driving methods are as follows:

1、同步带传动它也采用直流或交流伺服电机，通过同步带将旋转运动转换为直线运动，广泛应用在送料机构等场合。它适合长距离传动，传动的速度较高；但运动精度比较低，可承载的转距较小。

1. Synchronous belt drive also uses DC or AC servo motor to convert rotary motion into linear motion through synchronous belt, which is widely used in feeding mechanism and other occasions. It is suitable for long-distance transmission with high transmission speed, but its motion accuracy is low and its bearing torque is small.

2、滚珠丝杆传动   这是目前应用广、也成熟的一种传动方式，采用直流或交流伺服电机驱动，选用大导程的丝杆时可以获得较高的传动速度，定位精度和重复定位精度高，高速度可达 1m/s。

2. Ball screw drive is a widely used and mature transmission mode at present. It is driven by DC or AC servo motor. When large lead screw is selected, it can obtain higher transmission speed, high positioning accuracy and repeated positioning accuracy, and the high speed can reach 1m / s.

3、气缸传动这种传动方式具有结构简单、控制方便的特点；但由于其采用压缩气体作为动力，定位精度低，启停速度慢，往复运动的频率低。

3. Cylinder drive has the characteristics of simple structure and convenient control, but because it uses compressed gas as power, it has low positioning accuracy, slow start stop speed and low reciprocating frequency.

4、直线电机传动这是目前逐渐兴起的一种直线运动传递方式，具有结构形式简洁，定位精度高，易于实现高速高精运动的控制。它直接将电能转换成机械能，减少了滚珠丝杆、传送带、涡轮螺杆等中间转换环节；但对直线电机的控制系统相当复杂，目前还不是很成熟，也相当昂贵，限制了它的广泛使用。

4. Linear motor drive is a kind of linear motion transmission mode which is gradually rising at present. It has the advantages of simple structure, high positioning accuracy and easy to realize the control of high-speed and high-precision motion. It directly converts electrical energy into mechanical energy, reducing the ball screw, conveyor belt, turbine screw and other intermediate conversion links; but the control system of linear motor is quite complex, not very mature at present, and the price is also quite expensive, which limits its wide use.
