Abstract
Precision detection technology as the key to promoting industrial development and the efficiency of detection to some extent reflects the development of the manufacturing sector; for machine vision inspection system has the advantage of high precision, on-line, real-time, non-contact, etc., with industrial production field of automation requirements continue to increase, machine vision inspection applications in various fields more widely, such as assembly line parts recognition positioning, size and location of the measurement of mechanical components, parts flaw detection, mechanical parts assembly Appearance inspection and product testing completely.
In order to improve the positioning accuracy of the machine vision inspection system in the camera and the camera's automatic adjustment realization, this paper actual industrial production requirements described in detail how mechanical structure design, hardware selection and the hardware wiring and accuracy of the calculation and design work. The hardware design includes how to choose the right controller to control the process, drives, PC and network monitoring software, communications and other machine vision inspection station automatic control system, an important part; precision computing design of the main means by calculating the stepper motor step Relationship angle from its high-speed pulse frequency to achieve precise positioning camera movement position.
Keywords: Automatically Detecting System, PLC, Stepper Motor.
