Application of EtherCAT protocol in glue coating robot control system

Industry Background

The glue coating machine is an important part of the photolithography process in the front-end process of wafer manufacturing. In the back-end process, it mainly applies the glue coating process of packaging technology. The control system on the glue coating machine generally has the characteristics of nonlinearity and multi-input and multi-output, and the requirements for system response are also relatively high. The servo units of a glue coating machine must have the functions of linkage and independent movement at the same time.

Through the combination of EtherCAT technology and Hongke KPA Automation soft technology, the problem of strong glue application of each robot can be solved. At the same time, modern advanced industrial computer technology can be used to solve the problem that high-precision complex algorithms are difficult to achieve high real-time performance on motion control cards.

Control system based on Hongke EtherCAT soft PLC and IO module

The control system in this article is based on Hongke's HK-EX device and Automationsoft PLC under the EtherCAT system. Different from Mitsubishi and PLC used in traditional industrial sites, Hongke KPA Automationsoft PLC has higher flexibility and stronger compatibility with complex movements, making it more suitable for gluing and robot applications.

The control method used in the above cases revolves around PLC. PLC control system is a new type of industrial control device formed by introducing microelectronics technology, computer technology, automatic control technology, and communication technology. PLC control has high reliability and fast operation speed. It has been widely used in industrial industries such as semiconductor manufacturing, but it also has problems such as high cost and the need for users to have professional knowledge of PLC.

In addition to PLC control, relay control systems can also be used to achieve accurate and reliable control. Relay control systems are connected by devices and wires, and have the advantages of simple structure and low cost. At the same time, due to the simple principle, it is easy for engineering and technical personnel to master.
