Abstract
For the digital image acquisition workbench to realize automatic control in the X-Y direction, to complete the accurate positioning of the tested parts, and to realize the accurate focusing of the camera. According to the actual demand of industrial production, this paper describes how to design mechanical system, component selection and visual system. The design of mechanical system is mainly for the design and selection of X-Y NC workbench, including transmission parts, control system and step motor. Visual system design mainly includes industrial camera selection and visual software statement writing.
The digital image acquisition table can realize automatic control in the X-Y direction, complete the accurate positioning of the tested parts, and move up and down in the Z axis direction to realize the accurate focusing of the camera. In order to improve the positioning accuracy of the camera in the machine vision detection system and realize the automatic adjustment of the camera, this paper describes in detail how to design the mechanical mechanism, select the hardware and connect the hardware, and calculate the precision according to the actual industrial production requirements. The hardware design includes an important part of the automatic control system of machine vision detector, such as how to select the appropriate controller, control technology, driving equipment, upper monitoring software and network communication mode, etc. The precision calculation design mainly refers to the accurate location of the camera moving position by calculating the relationship between the step distance angle of stepping motor and its high speed pulse frequency.
