Abstract

The invention discloses a structure of an on-line appearance detector and a detection method thereof. The structure of the detector comprises a base, a complete machine frame, an upper cover plate and a side cover plate. A shading plate and a handle are installed on the side cover plate. The inner side of the base is provided with a light source, the light source is installed in a diffusion cover, a Y-axis screw rod is installed on the base, a screw rod mounting base is arranged on the Y-axis screw rod, a Z-axis rod is fixed to the screw rod mounting base and connected with a movable frame, a camera is fixed to the movable frame, and a support is further installed on the base. A method of detection by the detector comprises the steps of installing the detector above a to-be-measured workpiece; causing a computer to automatically start after electrification, and manually opening detection software; opening a light source, using a camera to take a picture, and adjusting shade of the light source and the position of the camera; taking the camera to shoot a whole picture of the to-be-measured workpiece, using software to calculate and analyze whether the to-be-measured workpiece is qualified, pointing out a defect position, and recording the pass rate. The structure of the on-line appearance detector is good in matching effect, manual errors are reduced, and product yield and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of welding detection, in particular to a structure of an online appearance detection machine and a detection method thereof. Background technique [0002] In the existing technology, plug-in components such as PCB boards for wave soldering are often manually inspected to see if the solder joints are qualified, subject to the inspection level of inspectors, product inspection is time-consuming and laborious, human errors are inevitable, and some use offline AOI (automatic optical inspection) and online AOI and on-site environment analysis, however, cannot meet the speed of the production line in terms of shooting speed and inspection time. In this regard, the designers improved the structure of the inspection machine, made the position of the camera and the light source adjustable, and greatly improved the detection effect and efficiency. Contents of the invention [0003] The purpose of the present invent...
