Abstract

The invention relates to the anti-fake field and discloses an apparatus used for detecting an anti-fake component and a method thereof. The anti-fake component possesses a magnetic area whose easy magnetization axis direction is a vertical direction. The apparatus used for detecting the anti-fake component comprises a magnetic sensor and a magnetization unit. The magnetization unit comprises a vertical magnetization unit and / or a horizontal magnetization unit. The vertical magnetization unit is used for making magnetic moment directions of all the magnetic areas in the anti-fake component be a vertical direction. The horizontal magnetization unit is used for making the magnetic moment directions of all the magnetic areas in the anti-fake component become a horizontal direction. The magnetic sensor is used for detecting the anti-fake component which is magnetized by the vertical magnetization unit and the anti-fake component which is magnetized by the horizontal magnetization unit respectively. In the invention, all the magnetic areas in the anti-fake component become the vertical direction and the horizontal direction successively; and through obvious difference of wave forms of the magnetic areas before and after being changed, distinguishing detection of the magnetic area whose easy magnetization axis direction is the vertical direction is realized.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to a device and method for detecting anti-counterfeiting elements. Background technique [0002] With the improvement of anti-counterfeiting performance of securities, various technologies have been adopted in securities to improve the anti-counterfeiting capability of security threads, for example, vertically oriented magnetic coding technology is used to improve the anti-counterfeiting ability of anti-counterfeiting components. In this regard, a scheme for detecting the above-mentioned vertically oriented magnetic encoding is proposed in the prior art. This scheme can realize the detection of the vertically oriented magnetic encoding. The magnetic moment direction of the magnetic region is a vertical direction, and then the horizontal magnetization unit of a specific size is used to make the magnetic moment direction of the magnetic region whose easy magnetization axis direction...
