Device and method for 360-degree bottle body production line front-light vision inspection

Abstract

The invention provides a device and method for 360-degree bottle body production line front-light vision inspection. The device comprises a front inspection station and a back inspection station which are arranged on a conveyor belt of a production line, a first inspection unit and a fourth inspection unit which are arranged on one side of the conveyor belt of the production line and a second inspection unit and a third inspection unit which are arranged on the other side of the conveyor belt of the production line; each inspection unit is composed of a set of cameras and a set of light sources. According to the device and method, the high-speed exposure characteristics of the industrial cameras and the light sources and light path crossing imaging are utilized, vision imaging covering the side face of a bottle body is achieved, industrial defects, such as dirty spots, loss, flashing, deformations and uneven thickness, of the bottle body are highlighted, the two closer inspection stations are adopted, the space utilization rate is improved, and the structure is compact and reasonable; in addition, through the set photographing order, camera imaging is non-interfering, the device and the method are very suitable for a high-speed integrated machine vision inspection system, and therefore the purpose of efficient inspecting and selecting of the bottle body production line is achieved.

Description

Technical field [0001] The invention relates to the technical field of fully automatic machine vision detection, in particular to a 360-degree bottle body assembly line front light vision detection device and method. Background technique [0002] The optical vision inspection system of plastic bottles generally adopts a multi-light source and multi-camera collaborative photographing mode, that is, the camera and the light source are placed on the same side of the bottle body, and the process defects on the bottle body are identified by the light and shade of the pattern. At present, the common inspection devices on the market use four inspection stations, which have low space utilization and loose structure, which cannot meet the needs of today's high-speed integrated machine vision inspection systems. Summary of the invention [0003] The purpose of the present invention is to provide a 360-degree bottle assembly line front light visual inspection device and method with compact...
