Tracing method of glass cover plate

Abstract

The invention discloses a tracing method of a glass cover plate. The method comprises the following steps: after the printing ink screen printing of the glass cover plate is finished, when a positioning line is subjected to screen printing, carrying out screen printing on the spare part printed with the printing ink on the back surface of the glass cover plate by using white printing ink to form a white square block; putting the glass cover plate on which the white square blocks are silk-printed into a tunnel furnace, and baking for 25 minutes at the temperature of 160 DEG C; generating a two-dimensional code according to the serial number information of the glass cover plate, and laser-etching the two-dimensional code on a white square block of the baked glass cover plate by adopting a UV marking machine; cleaning and laminating the glass cover plate with the laser-etched two-dimensional code; and performing code scanning inspection on the laminated glass cover plates one by one by using a code scanning gun, comparing the read information with the information in the system to judge whether the information is correct or not, and packaging to obtain the product. Two-dimensional codes are formed on the glass cover plates through laser etching, each glass cover plate is recognized in a scanning mode, two-dimensional code information recognized through scanning is directly imported into a system, the tracing function can be achieved, and the problem that tracing is difficult is solved.

Description

technical field [0001] The invention relates to a method for tracing a glass cover plate, which belongs to the technical field of glass preparation. Background technique [0002] With the rapid development of electronic products in modern life, the production of glass cover plates is also changing rapidly with the development of electronic products, and various development needs are also added, making the manufacturing process of glass cover plates more complex and diverse. There are more and more manufacturers making and producing glass cover plates. There are multiple manufacturers producing the same product at the same time. When customers report that a product is abnormal, they can only find the corresponding supplier through the delivery note or code at that time. batch. The printing code will exist in the same batch and use one code to print. Only the batch of product printing can be found, and the specific production process cannot be identified, which is prone to id...
