Article identification and sorting device and method thereof

Abstract

The invention discloses an article identification and sorting device and a method thereof. The article identification and sorting device comprises a main transmission belt, a disqualification article transmission belt, a robot system and a computer. The robot system comprises a robot controller, a Y-axis sliding groove and an X-axis sliding groove. A sliding block is arranged on the Y-axis sliding groove, and an optical camera and a mechanical arm are fixed on the sliding block. The invention further discloses a method of the article identification and sorting device. Disqualification articles can be identified by analyzing X-ray images and visible images, the disqualification articles are gradually moved to the disqualification article transmission belt through the mechanical arm. The article identification and sorting device and the method can automatically indentify and sort articles on a production line and have the advantages of being accurate, reliable and high in efficiency.

Description

technical field [0001] The invention relates to the field of automatic non-destructive testing, in particular to an X-ray image-based object identification and sorting device and method thereof. Background technique [0002] During the production, processing and packaging of products, the interior often does not meet the quality requirements or is mixed with foreign matter, resulting in unqualified products. The typical ones are: 1. In the process of processing and packaging food in food production and processing enterprises, some foreign matter is often mixed into the food, mainly including foreign matter such as metal, glass, stone, plastic and rubber. These foreign matters not only affect the The quality of food, and some foreign matter is difficult to detect with the naked eye, and it is easy to be eaten by consumers by mistake, causing food safety accidents. 2. Parts processing and casting enterprises, during the processing or casting process of the product, air, impur...

[0002] During the production, processing and packaging of products, the interior often does not meet the quality requirements or is mixed with foreign matter, resulting in unqualified products

The typical ones are: 1. In the process of processing and packaging food in food production and processing enterprises, some foreign matter is often mixed into the food, mainly including foreign matter such as metal, glass, stone, plastic and rubber. These foreign matters not only affect the The quality of food, and some foreign matter is difficult to detect with the naked eye, and it is easy to be eaten by consumers by mistake, causing food safety accidents

2. Parts processing and casting enterprises, during the processing or casting process of the product, air, impurities, etc. may be mixed inside, or the installation position of the internal parts is wrong or missing, which will lead to unqualified products, so it must be tested before leaving the factory

[0003] At present, the X-ray inspection system widely used in the production line is still based on visual inspection. Workers use the naked eye to judge product quality. Generally, there are the following problems: (1) The number of products inspected on the production line is very large, and the operators perform single and boring work for a long time , It is easy to cause visual fatigue, missed detection, false detection, etc.; (2) The foreign matter in some products is very small, and it is not easy to be noticed by the human eye on the fast scrolling screen; (3) It is difficult for the operator to handle the detection that needs to be quantified , for example, when inspecting the installation position of the internal parts of the product, the subjective factors of the operator account for a large proportion, which affects the consistency of the product; (4) when inspecting bulk materials, it is difficult to manually detect unqualified products The method only sorts out the unqualified product, but all the bulk materials in a range are classified as unqualified products and pushed out of the assembly line, resulting in waste
