Method and equipment for comprehensively detecting defect of blank support rings for PET (polyethylene terephthalate) bottles

Abstract

The invention discloses equipment for comprehensively detecting defect of blank support rings for PET (polyethylene terephthalate) bottles. The equipment comprises a frame, a reflecting mirror assembly and a camera. The equipment has the advantages that notch, rolling and wire scraping defect of the blank support rings can be detected by the aid of the equipment, and the detection precision can reach 99.9% at least; systems for detecting the blank support rings are free of dead zones, simple in structure, low in cost and good in robustness, and the like.

Description

[0001] The invention relates to the technical field of industrial automation detection, in particular to an all-round defect detection device for PET bottle embryo rings. Background technique [0002] At present, food safety issues are getting more and more attention from the government and the people. In the existing production process of beer, beverages and pharmaceuticals, the filling containers are required to meet the corresponding quality standards, and strict inspections must be carried out in every link of production. Among them, the quality inspection of the bottle mouth holding embryo ring is an important part of the production quality control. Defects in the embryo holding ring will affect the subsequent production process, and the defective rate of the product will increase, which will affect the reputation of the manufacturer. At the same time, when consumers drink beverages, they will be in close contact with the embryo ring, and the defects of the embryo ring m...

AI Technical Summary

Problems solved by technology

[0004] 1. Low detection accuracy: It is difficult to detect tiny defects, there are detection dead angles, and the detection accuracy is difficult to meet the requirements, which brings safety hazards to food production;

[0005] 2. Low detection efficiency: unable to meet the needs of high-speed automatic production;

[0006] 3. The labor cost is high, and the inspection workers are prone to fatigue, so the inspection quality cannot be guaranteed

At the same time, there is also a certain impact on the health of workers;

[0007] 4. The manual method is not conducive to the requirements of today's information management

[0008] The difficulty in the detection of embryo-bearing ring defects is that the defects are usually small and difficult to detect; the manifestations of defects are various, and it is difficult to detect them with a single method

At the same time, the viewing angle range that can be obtained by a single camera is small, and multiple stations are required to achieve all-round detection, which greatly increases the complexity and cost of hardware
