Abstract

The present invention relates to a visual inspection apparatus. The visual inspection apparatus is an apparatus which photographs an inspection object using a camera to determine whether the inspection object is defective or not. The vision inspection apparatus comprises: a stage part on which an inspection object is seated; a camera part including a lens and an image detection part, wherein the camera part photographs an image of the inspection object; an illumination part for illuminating the inspection object; and a visual processing part that reads the image photographed by the camera part to determine whether the inspection object is defective or not. Within a lateral camera of the camera part, which is slopingly installed with respect to a line perpendicular to a plane on which the inspection object is seated, a surface of the image detection part is slopingly installed at a predetermined angle with respect to a plane perpendicular to a line of connecting a center of the inspection object to a center of the camera lens of the lateral camera. Thus, since resolution may be improved and the optical path difference is compensated for, the image of the inspection object may be precisely read. Also, a lateral image of the inspection object may be clearly photographed without changing the size of the apparatus.

Description

technical field [0001] The present invention relates to a visual inspection device, in particular, to a visual inspection that can correct the optical path difference of the inspection object by setting the photosensitive device in the side camera disposed in the visual inspection device at an incline. 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) and the development of precision assembly equipment for precise assembly of the above-mentioned surface mount components and the technology to utilize various assembly equipment. [0003] Typically, a surface mount production line consists of equipment such as surface mount machines and visual inspection devices. [0004] The above-mentioned surface mount machine is used as a de...
