Problems solved by technology

[0005] Based on this, the purpose of the present invention is mainly to solve the problem that the existing AOI detection system only recognizes the device of a single attribute parameter when detecting, and expands the selection range of related devices when the PCB board is made by setting an alternative attribute parameter library

Abstract

The invention relates to an AOI device database addition method and a system thereof. The method comprises the following steps: current image information of one device on a PCB is scanned and acquired; the current image information is respectively compared with at least a set of reference image information in a parameter database of a target device corresponding to the device so as to judge whether the information match each other; if the current image information doesn't match the reference image information in the parameter database and one replaceable parameter add command is received, the current image information of the device is added and stored in the parameter database. According to the invention, an attribute parameter of the detected device can be compared with a related attribute parameter of an original standard device and also can be compared with a related attribute parameter of a substituted device which still meets requirements, and it can be judged that the detected device meets requirements if the attribute parameter accords with any one of the related attribute parameters. Selection range of related device in the PCB card manufacturing process is widened.

Description

technical field [0001] The invention relates to the field of circuit board production, in particular to an AOI device detection method and system. Background technique [0002] AOI (Automatic Optic Inspection) is called automatic optical inspection. It is a device based on optical principles to detect common defects encountered in welding production. For example, it is often used to detect PCB boards to ensure product quality. [0003] AOI is a new type of testing technology that has only emerged in recent years, but it has developed rapidly. At present, many manufacturers have launched AOI testing equipment. When performing automatic detection, the machine automatically scans the PCB board card through the camera to collect images, and compares the tested solder joints with the qualified parameters in the database. After image processing, the defects on the PCB board card are checked out, and passed The display or automatic flag will display the corresponding defects for r...
