Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] The invention provides a method for detecting a bottle mouth defect, comprising:

[0022] S1. Divide the detection area of ​​the bottle mouth, and use the parallel computer mechanism to simultaneously detect the first inner ring, the second inner ring, the evaluation ring, the sealing ring and the inner sealing ring;

[0023] S2. Summarize the test results, and finally output the comprehensive test result for the bottle mouth. If there is no less than one test item with abnormal output, the test result is abnormal, otherwise the test result is normal.

[0024] Wherein, in the step S1, the first inner ring, the second inner ring, the evaluation ring, the sealing rin...

Abstract

The invention discloses a bottle mouth defect detection method which comprises the steps as follows: S1, a bottle mouth is subjected to detection area division and is divided into a first inner ring, a second inner ring, an evaluation ring, a sealing ring and an inner sealing ring area, and all areas are detected; and S2, all detection results are collected, a comprehensive detection result is output, if all the detection results are normal, that the bottle mouth detection is normal is output, and otherwise, that the bottle mouth detection is abnormal is output. According to the bottle mouth defect detection method, the detection speed and the detection accuracy are high, the performance is stable, the debugging is convenient, and the method is suitable for long-time and real-time continuous detection on bottle mouth defects on a high-speed automated assembly line.

Description

technical field [0001] The invention relates to the technical field of industrial automatic detection, in particular to a method for detecting a defect in a bottle mouth. Background technique [0002] At present, my country's food safety management system is advancing rapidly, and people are paying more and more attention to food safety. The European HACCP standard and my country's GB4927-91 standard both put forward strict requirements for the detection of empty beer bottles. In the existing production process of beer, beverages and pharmaceuticals, the filling containers are required to meet the corresponding quality standards. Every step of production needs to be inspected. When unqualified bottles enter the market, not only consumers may be harmed, but also for the products. The manufacturer's economy and reputation will also be damaged. At present, the detection of empty beer bottles mainly relies on manual detection, but manual detection has the following disadvantage...
