Abstract

The vision testing device of the present invention is a vision testing device with enhanced image clarity for discriminating a satisfactory or a non-satisfactory testing object by shooting a testing object assembled or mounted during a component assembly process, and comparing the image taken with a previously inputted target image, and comprises: a stage part for fixing or transferring the testing object to the testing location; a lighting part located on the upper portion of the stage part, for providing lighting to the testing object; a first camera part located in the center of the lighting part, for obtaining a 2-dimensional image of the testing object; a second camera part placed in plurality on the side of the first camera part; a grid pattern irradiating part placed between the camera of the second camera part and a camera; a vision processing unit for reading the image taken in the first camera part and the second camera part, and discriminating whether the testing object is satisfactory or non-satisfactory; a control unit for controlling the stage part, the light irradiating part, and the first and the second camera parts; and a light diffusion part. The present invention enhances the uniformity of light being irradiated on the surface of the testing object. In addition, the present invention enables a more clear shooting of an image by removing a half mirror placed on the front of a camera part in the center, and enables convenient maintenance by miniaturizing the size of the device and dispersing the configuration.

Description

technical field [0001] The present invention relates to a visual inspection device. Specifically, it relates to a method of using a light diffusion plate to improve the uniformity of light irradiating an inspection object, using a variety of grid stripes to inspect the height, and removing the half mirror arranged in front of the camera for photographing the inspection object to improve image clarity. Visually inspect the device. Background technique [0002] In general, surface mount technology (SMT; Surface Mounting Technology) for assembling surface mount components such as printed circuit boards (PCBs) includes: technologies for miniaturization / integration of surface mount components (SMD; Surface Mounting Device) , The development of precision assembly equipment for the precise assembly of the above-mentioned surface mount components and the technology of using various assembly equipment. [0003] The surface mount production line consists of equipment such as surface...
