Problems solved by technology

[0004] When using AOI optical inspection equipment to detect the PCB after the components are placed, it is necessary to detect whether the components on the PCB board are missing, whether the placement is correct, the position accuracy of the placement, and the polarity of the placement. AOI optical detection equipment has high detection requirements to ensure the accuracy of the detection number, but the light source irradiation angle of the existing AOI optical detection equipment is fixed, and the angle cannot be adjusted according to the format of the patch, which reduces the accuracy of AOI optical detection equipment. The detection accuracy of the detection equipment makes it easy for unqualified PCB boards to flow into the next process, increasing the scrap rate of PCB boards

Abstract

The invention discloses light source reflection speed adjusting type AOI optical detection equipment, which belongs to the field of optical detection. The light source reflection speed adjusting type AOI optical detection equipment comprises an equipment body, a workbench and a light and shadow fixing frame located on the upper side of the workbench are installed at the upper end of the equipment body, a light and shadow detection device is installed on the light and shadow fixing frame, andthe light and shadow detection device comprises a sensor sleeve. Through mutual cooperation of an independent angle adjusting air bag, an arc section reflecting plate and a fixed-point adjusting support plate, the angle of a light beam is effectively adjusted according to the format of a patch on a PCB when the PCB is detected so as to reduce the phenomenon that the imaging of a main image camera is inaccurate due to the light refraction of the patch, the detection precision of the AOI optical detection equipment is improved, unqualified PCBs are effectively prevented from flowing into the next working procedure, the rejection rate is reduced, waste of raw materials is reduced, the unqualified PCBs can be repaired in time, and the economic benefits of PCB machining are improved.

Description

technical field [0001] The invention relates to the field of optical detection, and more specifically, relates to a light source reflection and quick adjustment type AOI optical detection equipment. Background technique [0002] The full Chinese name of AOI (Automated Optical Inspection) is automatic optical inspection, which is a device based on optical principles to detect common defects encountered in welding production. In the PCB manufacturing industry, the miniaturization and densification of components has always been a development trend. This has prompted manufacturers to install AOI equipment for their production lines. Because it is impossible to rely on manual labor to perform reliable and consistent detection of finely distributed components, and to keep accurate detection records. However, AOI can carry out repeated and accurate detection, and the storage and release of detection results can also be realized electronically. [0003] AOI optical inspection equ...
