Description

Technical Field

[0002] A QR code is a black and white graphic that records data symbol information and is distributed on a plane using certain geometric shapes according to a certain pattern. A QR code is often attached to the surface of a product to facilitate the entry of the product. After the QR code is attached, the position of the QR code on the product needs to be detected, and the products without the QR code attached need to be removed using a rejection device.

[0003] After the existing QR code is labeled, it is usually moved to a detection and rejection device for detection. During the movement, dust and other impurities may adhere to the surface of the QR code, causing the QR code to be blocked during the detection process and be rejected, reducing the detection effect of the product QR code. Therefore, a high-speed QR code detection and rejection device is proposed to solve the above-mentioned problems. Utility Model Content
