Vision detection system and detection method

Abstract

The invention relates to a vision detection system. The vision detection system comprises a rack, a digital camera, a light source, a PLC (Programmable Logic Controller), an industrial personal computer, a steering device and a lens, as well as a support, a stepping motor, an ejecting device and an optical fiber sensor, wherein the steering device comprises a device body and a prism, and the light source and the lens are arranged on the support. The light source is a bilateral telecentric light source, and the lens is a bilateral telecentric lens. The ejecting device is arranged on a guide rail and controlled by the stepping motor, and the optical fiber sensor is arranged above the guiderail and controlled by the PLC. In addition, the invention further discloses a detection method of the vision detection system. Compared with the prior art, the vision detection system has high detection efficiency, is accurate, does not need manual intervention, effectively solves the positioning problem of products to be detected through the arrangement of the ejecting device, leads the camera to be horizontally arranged by the arrangement of the steering device, thus greatly saving the space of the device and enabling the design to be more compact.

Description

Technical field [0001] The invention relates to a detection device, specifically, a device that uses vision to detect parts, and the invention discloses its detection method. Background technique [0002] At present, the quality inspection of the appearance and shape of the well-known batch products are all detected by the human eye. Because the judgment of the human eye is not easy to quantify and execute, the human eye is prone to fatigue, people are prone to emotional, and some high temperature or toxic environments cannot be long. Time work and other factors have led to a high rate of misjudgment and misjudgment in the quality inspection of product appearance and appearance. In some places, there have been attempts to use cameras to acquire images to replace human eye detection, but they all manually place a single product directly on the workbench for photographic inspection, take it away after the inspection, and put a new one. This is repeated and automated. The detection...
