Description

Technical Field

[0001] The present invention relates to the technical field of island production line detection and identification, and in particular to an automatic detection and identification device based on a working island production line. Background Art

[0002] The work island production line, also known as the island production line or modular production island, is a production mode that splits the traditional continuous production line into multiple independent small production islands. Each production island independently completes the production of a certain variety of products, has its own workers, equipment and production rhythm, and different islands are independent and non-interfering with each other, but always maintain a certain degree of coordination in product production. The work island production line is mostly used in large-scale assembly production, such as automobile production. During automobile assembly production, it is necessary to use a barcode scanner to scan the barcode on the accessories. By scanning the barcode, the workers or equipment on the production line can quickly identify the type and quantity of parts, thereby ensuring that the correct parts are installed on the car.

[0003] At present, a detection and identification device is set up on the working island production line to identify the barcode. However, the light in the factory is changing. The light change may have a significant impact on the recognition effect of the automatic detection and identification device on the working island production line, because different light will produce different effects on the surface of the barcode, which may cause the barcode to be blurred and difficult to identify quickly, and even cause serious recognition errors. Therefore, the change of light angle may lead to a decrease in recognition accuracy. However, the existing detection and identification device cannot adjust the light angle when detecting and identifying the barcode, and the recognition accuracy is low. Therefore, we propose an automatic detection and identification device based on the working island production line. Summary of the invention
