Embodiment Construction

[0010] As shown in Figure 1, the laser beam generated by a laser generating device such as a laser tube or a semiconductor laser head is focused and adjusted through an optical system, so that the laser is accurately focused on the carrier 1 to be printed; The high temperature is generated instantaneously to ablate the carrier into a concave shape, and the laser spot is moved according to the requirements of the barcode, leaving a concave three-dimensional barcode 2 on the carrier 1 .

[0011] As shown in Figure 2, it is a convex barcode. The laser beam generated by a laser generating device such as a laser tube or a semiconductor laser head is focused and adjusted through an optical system, so that the laser is accurately focused on the carrier 1 to be printed; The place where the laser point hits will instantly generate high temperature to ablate the carrier into a concave shape. According to the requirements of the barcode, the laser point is moved on the carrier around the ...

Abstract

This invention has publicized a kind of three-dimensional bar code. It includes supporter (1) and bar code (2), the following is the characters of it: The bar code (2) is concave or convex. The bar code in this invention belongs to physical pothole rather than the common chemical ink and carbon powder used in print. So, any alter will not occur during the preservation process for it, it will not fade and the handwriting on it will not become fuzzy, when the time goes, contacting with liquid, heat, glare, and after a long preservation under adverse conditions. It is especially suitable for the preservation of file, the print of the important documents, and the bar code used under the adverse conditions.

Description

technical field [0001] The invention belongs to the technical field of barcodes, and in particular relates to three-dimensional barcodes. Background technique [0002] Existing barcodes use different printers to print flat barcodes on the carrier from ink, toner, heat transfer, etc., and are specifically divided into one-dimensional barcodes and two-dimensional barcodes; one-dimensional barcodes only have the function of storing labels , Two-dimensional barcodes can also store data. Its disadvantages are: it is only a carrier for recording information and does not have anti-counterfeiting performance; barcodes will affect the recognition of barcodes when exposed to water, heat, strong light or stored in harsh environments for a long time. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a three-dimensional barcode that does not fade and has an anti-counterfeiting function. [0004] The technical so...
