Abstract

The invention relates to a control system of an AOI (automatic optic inspection) detection device. The control system comprises an industrial personal computer and a processor, and is also provided with a touch screen for inputting an instruction and parameters and displaying an image and a detection result; an image processing software system runs in the processor; the industrial personal computer respectively controls the processor and a visual system responsible for acquiring the image and a mechanical system of the AOI device; the touch screen and the processor respectively perform bi-directional information interaction with the industrial personal computer. The touch screen is used as a human-computer interaction interface, not only has a display output function, but also has a function of inputting the instruction and setting the parameters and can completely substitute conventional mouse, keyboard and a conventional monitor, so that the space occupation rate of the AOI device is reduced, and the AOI device is simpler in structure and more convenient to operate. The processing system simultaneously contains a rule inspection method and a figure identification inspection method, which can be optionally used or simultaneously used, and the detection capacity is improved.

Description

technical field [0001] The invention relates to an AOI detection device for a printed circuit board, in particular to a control system for the AOI detection device. Background technique [0002] The full name of AOI (Automatic Optic Inspection) is automatic optical inspection, which is a device based on optical principles to detect common defects encountered in welding production. AOI is a new type of testing technology emerging, but it is developing rapidly, and many manufacturers have launched AOI testing equipment. During automatic detection, the machine automatically scans the PCB through the camera, collects images, compares the tested solder joints with the qualified parameters in the database, and after image processing, checks out the defects on the PCB, and displays / labels the defects through the display or automatic signs out for repair by the maintenance crew. [0003] The basic structure of current AOI equipment is generally composed of three main parts: vision...
