Step-by-step computer vision inspection device carrying movable darkroom

Abstract

The invention discloses a step-by-step computer vision inspection device carrying a movable darkroom, and belongs to the technical field of mechatronics. The step-by-step computer visual inspection system comprises a visual inspection computer, a single-chip microcomputer, a stepping motor, a lead screw, a display, a darkroom and an auxiliary illuminating lamp, wherein the darkroom, the camera andthe auxiliary lighting lamp are installed on a sliding table of the lead screw through a cantilever structure, the stepping motor provides power for the lead screw and is controlled through the single-chip microcomputer, the single-chip microcomputer and the visual inspection computer are in two-way communication through a serial port, and the result output of the visual inspection computer is displayed through using a display. The single-chip microcomputer and the visual inspection computer are in two-way communication through the serial port, response is quick, and accurate control can be achieved. The transverse movement of the darkroom adopts a structure that the stepping motor drives a screw rod sliding table and is controlled by programming of the single-chip microcomputer, and compared with traditional PLC control, the single-chip microcomputer can achieve miniaturization and low cost.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and in particular relates to a computer vision detection device for component assembly detection in manufacturing industry. Background technique [0002] As the country puts quality at a strategic level, it puts forward the requirements of enterprises to improve quality management level and speed up enterprise quality technology innovation, and people's increasing pursuit of high-quality living standards, manufacturing enterprises improve quality management level and reduce product defect rate It has become an important means to improve their own competitiveness and the foundation of survival. In the traditional manufacturing industry, especially the old production lines, workers are still mainly relied on for assembly and inspection, and human operation is a very large unreliable factor for quality management, and it is easy to cause errors and omissions. With the rapid development of comp...

AI Technical Summary

Problems solved by technology

However, the traditional visual inspection technology is mainly mastered by well-known foreign equipment manufacturers. The purchase cost of equipment and software is very high, and the inspection program has been highly integrated, and users cannot change it independently. It needs to be equipped with a large darkroom to cover the entire detection part, which is often impossible to arrange for a production line with a compact layout
