Abstract

The invention relates to a rapid detection method and device for stamping valve plate parts, which comprises an intelligent camera, a lens is installed below the intelligent camera, the intelligent camera and the lens are assembled together, the intelligent camera is connected with an image detection algorithm module, the lens is arranged above a conveying belt, the voltage-stabilizing direct-current cold light source is arranged below the conveyor belt, an inductive sensor is arranged beside the direct-current cold light source, a drainage plate is arranged on one side of the conveyor belt, an opening of the drainage plate is gradually reduced so as to guide a sample to move to the position near the center line of the conveyor belt, and the inductive sensor is used for detecting the arrival position of the sample. The PLC module performs delay control to trigger photographing, and the telescopic air cylinder is arranged on the side, away from the drainage plate, of the conveying belt.

Description

technical field [0001] The invention belongs to the technical field of instruments and devices, and in particular relates to a rapid detection method and device for stamping valve parts. Background technique [0002] Spare parts such as valves and gaskets are used in large quantities on some special machinery and equipment and play a very important role. For example, gas compressors are used for special gas compression. The quality of the compressor valves and the accuracy of the valves are directly related. It affects the life and cooling effect of the compressor. The valve plate is the most impacted part in the compressor. It must be precision stamped. The stamping processing speed is fast, and the corresponding part detection cycle is required to feedback and control the stamping process. From the actual According to the inspection of the production line, the increase in production speed will also lead to an increase in the defect rate of parts. It is necessary to remove ...
