Problems solved by technology

[0003] With the development of industrial castings, the installation density of mounting holes and surface mount parts is higher, and the traditional detection technology cannot adapt to the new quality control of workpieces and surface mount parts in terms of technology and speed. On-line production quality control and testing has brought great challenges
[0004] At present, workpieces and surface mount components have many types, different shapes, and different colors. Due to the design limitations of existing optical detection devices, it is impossible to be completely suitable for the detection of all surface mount components. Therefore, the existing optical detection The detection of surface mount components with different shapes and colors by the device leads to many problems and difficulties. Therefore, an automatic optical inspection system (AOI) for quality control of workpieces and surface mount components is needed to realize the detection of workpieces and The automatic detection of installation defects of its surface mount parts, so as to make up for the defects of the existing technology

Abstract

The invention relates to an automatic optic detecting system and method. The system comprises a mechanical system and a control system, wherein the mechanical system is mainly composed of a support, a detecting platform, an image collecting box, a cylinder positioning assembly and a workpiece tray; and the control system is mainly composed of an image collecting assembly, a light source controller, an LED (Light Emitting Diode) light source, a singlechip, a PLC (Programmable Logic Controller) module and a computer. According to the method, template data of a to-be-detected workpiece are obtained through a part detecting module; a template database is established; the data of the template database is derived from the picture signals of a qualified workpiece; and the picture signals of the qualified workpiece are simultaneously collected by digital cameras at multiple positions and serve as a comparison standard of detecting the picture signals of the same to-be-detected workpiece. The automatic optic detecting system disclosed by the invention has the characteristics of non-contact, multidimensional detection, fastness, high efficiency, accuracy and the like and has the advantages that the workpiece and surface mounted components thereof can be effectively detected and managed and the automatic detection of installation defects of the workpiece and the surface mounted components of the workpiece is realized.

Description

technical field [0001] The invention relates to photoelectric detection technology, in particular to an automatic optical detection system and method, which are used to detect and manage workpieces and surface-mounted parts thereof, and realize automatic detection of installation defects of workpieces and surface-mounted parts thereof. Background technique [0002] In the past ten years, automatic optical inspection system (AOI) has been widely used in surface mount printed circuit board production lines. The application of the AOI system overcomes the disadvantages of manual inspection such as high labor intensity, eye fatigue, high missed inspection rate, and human factors, greatly improving the inspection speed and quality, improving production efficiency, and reducing production costs. [0003] With the development of industrial castings, the installation density of mounting holes and surface mount parts is higher, and the traditional detection technology cannot adap...
