濟(jì)南雙組份打膠機(jī)在日常中用到的驅(qū)動(dòng)方式有哪些？
濟(jì)南雙組份打膠機(jī)的控制和檢測(cè)系統(tǒng)是軟件和硬件的集成，是整個(gè)系統(tǒng)的核心所在，主要功能有：對(duì)被控制的各個(gè)子系統(tǒng)的運(yùn)動(dòng)性能進(jìn)行調(diào)試， 點(diǎn)膠時(shí)子系統(tǒng)初始參數(shù)的設(shè)置，協(xié)調(diào)各個(gè)子系統(tǒng)之間的工作，對(duì)子系統(tǒng)的工作狀態(tài)進(jìn)行監(jiān)測(cè)，工作氣壓和溫度數(shù)據(jù)的采集、傳送、處理等。
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.
雙組份打膠機(jī)點(diǎn)膠過(guò)程持續(xù)較短， 一般為幾十毫秒到幾秒鐘的時(shí)間， 由于電磁閥為開(kāi)關(guān)控制，因此要提高控制精度，只有縮短采樣周期進(jìn)行實(shí)時(shí)測(cè)量，以及減少電磁閥的動(dòng)作誤差的方法來(lái)具體實(shí)現(xiàn)。
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.
具體對(duì)控制系統(tǒng)的實(shí)現(xiàn)來(lái)說(shuō)，就要求系統(tǒng)定時(shí)精度誤差能夠保證在 ms 級(jí)以下。這就對(duì)控制系統(tǒng)的實(shí)時(shí)性提出了很高的要求。因而智能點(diǎn)膠控制系統(tǒng)的核心技術(shù)之一就是如何完成這一高實(shí)時(shí)性的任務(wù)。
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.
在生產(chǎn)應(yīng)用中常用到的驅(qū)動(dòng)方式有：
In the production application, the commonly used driving methods are as follows:
1、同步帶傳動(dòng)它也采用直流或交流伺服電機(jī)，通過(guò)同步帶將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)換為直線運(yùn)動(dòng)，廣泛應(yīng)用在送料機(jī)構(gòu)等場(chǎng)合。它適合長(zhǎng)距離傳動(dòng)，傳動(dòng)的速度較高；但運(yùn)動(dòng)精度比較低，可承載的轉(zhuǎn)距較小。
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、滾珠絲桿傳動(dòng) 這是目前應(yīng)用廣、也成熟的一種傳動(dòng)方式，采用直流或交流伺服電機(jī)驅(qū)動(dòng)，選用大導(dǎo)程的絲桿時(shí)可以獲得較高的傳動(dòng)速度，定位精度和重復(fù)定位精度高，高速度可達(dá) 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、氣缸傳動(dòng)這種傳動(dòng)方式具有結(jié)構(gòu)簡(jiǎn)單、控制方便的特點(diǎn)；但由于其采用壓縮氣體作為動(dòng)力，定位精度低，啟停速度慢，往復(fù)運(yùn)動(dòng)的頻率低。
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、直線電機(jī)傳動(dòng)這是目前逐漸興起的一種直線運(yùn)動(dòng)傳遞方式，具有結(jié)構(gòu)形式簡(jiǎn)潔，定位精度高，易于實(shí)現(xiàn)高速高精運(yùn)動(dòng)的控制。它直接將電能轉(zhuǎn)換成機(jī)械能，減少了滾珠絲桿、傳送帶、渦輪螺桿等中間轉(zhuǎn)換環(huán)節(jié)；但對(duì)直線電機(jī)的控制系統(tǒng)相當(dāng)復(fù)雜，目前還不是很成熟，也相當(dāng)昂貴，限制了它的廣泛使用。
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.
