Title  the Controller Design of Non-contact Handling System Based on Single Chip Microcomputer

Abstract

With the speeding-up of the industrial automation process, increasingly higher requirements for the handling device are put forward in the activities of producing and manufacturing high-tech productions. Among the devices, the one which adopts the technique of non-contact has a broad market prospect, for the reason of that the shortcoming of traditional handling, which is easy to result in product quality problems, can be well overcome by it. So, researching on the non-contact handling system and designing its stable, efficient controller make important practical significance.

In this paper, the composition of existing execution system is analyzed, and control modes of the main controlled-components are introduced after consulting related materials. A controller for the handling system is designed based on AVR chip after establishing the system’s overall function structure. The main works are to design hardware circuit of the control system, complete the programming of AVR chip and build the control platform on PC. The controller can realize dual functions both of controlling with the operation panel and controlling on the remote terminal of upper-computer. With the tool of computer, it can complete online programming for the sucker’s action sequence on the human-computer interaction interface. Finally, by debugging system’s hardware and software after the test platform is built and the controlling experiment, the feasibility of control system is verified.
