Design and Analysis Ofautomatic Inspection Device

The need for good quality products is felt by the industries to survive in today’s competitive market. To achieve 100% good quality, 100% inspection is necessary. Automatic inspection is the only possibility to attain this goal. Hence our project deals with developing an automated inspection system. This paper brings out the cost effective designs and fabrication of robot arm for inspection using machine vision technique. In this system, machine vision technology is used. It constitutes the image acquisition, image processing and image interpretation. Image acquisition is done using a digital camera and rest of the process is done by using an image processing tool from MATLAB software bundle. The digital camera which obtains the image of the object to be inspected is connected to the system where required software is loaded and the necessary programs are developed. The image is processed and the result is interpreted. To further automate the system and to reduce the part handling time a robot arm was designed and fabricated to satisfy the objective i.e. to move near the object to be inspected on the inspection table. Robot arm of required work volume and payloads was designed and fabricated. This robot arm is interfaced through a D.C motor device system to a microcontroller and its motion is controlled. Actuating the robot motion is achieved by interfacing the D.C motor which is used to move the robot arms with microcontroller kit and required circuits. The delays and required programs were generated in the microcontroller program written in it. This program controls the motion of the robot arms. This system involves in reducing the total inspection time and cost involved.
