Technology for effectively removing QR code printed on products realizing information traceability

Abstract

The invention relates to a technology for effectively removing a QR code printed on products realizing information traceability. According to the invention, QR code printed on the products is irradiated with ultraviolet light, and then is sprayed with glass water, after 10 minutes, the powder is sprinkled, the powder is irradiated at the high temperature of 60 to 70 DEG C, and finally the surfaceof the product is washed with deionized water. The ultraviolet light is used for irradiation to remove the bacteria on the surface of the product, the effect destroying of bacteria on the glass watercan be avoided, the glass water does not damage the glass and does not immediately remove the ink on the glass, the fading tendency of the ink on the glass is reduced with time, thereby covering and hiding functions are achieved, and a film is formed when the glass water is sprayed on the glass, the powder is used, the quicklime contained in the powder encounters water, the high temperature is used, the firm is quickly adsorbed, the glass with the ink is adsorbed cleanly, after drying, the secondary coverage is avoided, the surface is cleaned, and the ink is removed without wiping.

Description

technical field [0001] The invention relates to the technical field of information traceability, in particular to a technology for effectively removing two-dimensional codes printed on products that realize information traceability. Background technique [0002] In the daily production process of the factory, there is a problem that a single product cannot be effectively and quickly identified. When a product or a batch of products is abnormal, the process point and equipment where the product problem occurs cannot be quickly located, so that take targeted measures; [0003] When the product starts to be produced, a unique identification and confirmation QR code is printed on the product, and the information is collected and stored by the SCADA system; [0004] In all subsequent production processes, the equipment will read and identify the unique two-dimensional code imprint, and then the SCADA system will collect and read the information and store it; [0005] In some se...
