Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] In order to improve the anti-counterfeiting ability of the anti-counterfeiting element, the anti-counterfeiting element usually includes a magnetic region with the direction of the easy magnetization axis in the vertical direction (indicated by the symbol V in the drawings), and it can also include the direction of the easy magnetization axis in a non-vertical direction ( For example, a magnetic region in which the direction of the easy axis of magnetization is horizontal, the direction of the easy axis of magnetization is random, etc.) (indicated by symbol P in the drawings). The present invention provides a detection device and a detection method for su...

Abstract

The invention provides a detection method and device capable of achieving vertically oriented feature recognition with regard to the current station that in the prior art, no technology can detect an anti-counterfeiting element provided with magnetic areas of which the easy magnetization axis direction is the vertical direction. The detection device comprises a magnetic sensor and a magnetization unit. The magnetization unit comprises a horizontal magnetization unit and / or a vertical magnetization unit, wherein the vertical magnetization unit is used for making the magnetic moment direction of all magnetic areas in the anti-counterfeiting element be the vertical direction; the horizontal magnetization unit is used for only making the magnetic moment direction of the magnetic areas, of which of the easy magnetization axis direction is the non-vertical direction before the magnetization unit is magnetized, in the anti-counterfeiting element change to be the horizontal direction. The magnetic sensor is used for detecting the anti-counterfeiting element after the anti-counterfeiting element is magnetized by the magnetization unit.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to a method and device for detecting anti-counterfeiting elements. Background technique [0002] Along with the improvement of the anti-counterfeiting performance of the securities, various technologies have been adopted on the securities to improve the anti-counterfeiting capability of the security line. The combined application of two or more magnetic materials has become a new development direction. WO2011154088 proposes a method for detecting a machine-readable security thread code composed of two magnetic materials. However, this method cannot realize the detection of the magnetic region whose axis of easy magnetization is perpendicular to the direction. Contents of the invention [0003] Aiming at the current situation that there is no technology in the prior art that can detect anti-counterfeiting elements with magnetic regions whose axis of easy magnetization is vertic...
