Embodiment 1

[0014] The overall structure of the double-sided automatic detection device for coins of this embodiment is shown in Figure 1, including: a funnel coin lowering device A, used to receive finished coins stamped in the previous process; The coins at the coin outlet are sorted and transported to the detection device; the front and back simultaneous detection part C is used for simultaneous detection of the front and back of the coins and rejecting defective coins.

[0015] Refer to Fig. 2, Fig. 3 and Fig. 5 and Fig. 6 for the specific structure. The funnel coin lowering device A and the coin conveying device B are the same as the prior art. , coin belt 5 etc. constitute. The detection part C is composed of a detection slope 6, a reverse mirror 7, a parallel light source 8, a line camera 10, a front mirror 11, a coin picking mechanism 12, and an imaging slit 13. One end of the detection surface is connected with the output end of the coin feeding belt, and the other end is output...

Abstract

The invention relates to an automatic detection device of two sides of a coin, which belongs to the technological field of detection device. The device comprises a detection surface which is used for bearing the coin, a parallel light source, and a linear array camera which is connected with an image processing system; the detection surface is arranged obliquely; the inclination is longer than the angle of friction of the coin and the detection surface; the surface is provided with an imaging slot with the length more than the diameter of the coin; a front reflecting mirror and a back reflecting mirror are respectively above and below the detection surface of the imaging slot; one side of the detection surface is provided with the parallel light source and the linear array camera; the front reflecting mirror and the back reflecting mirror reflect two parallel beams of the parallel light source respectively upwards and downwards to the imaging slot, and secondarily reflect the reflected light of the imaging slot to the position of the linear array camera. The automatic detection device has the significant advantage of high efficiency, avoids the forced transmission of the coin, and thus reduces the damage; the conveying distance of the coin is short; thus the structure is compact and the size is small.

Description

technical field [0001] The invention relates to a coin surface quality detection device, in particular to a double-sided automatic detection device for finished coin or blank cake, which belongs to the technical field of detection equipment. Background technique [0002] As far as the applicant knows, the existing automatic coin detection devices all adopt the method of detecting the front and back separately, and there is no device for simultaneous detection of the front and back so far. Therefore, the existing automatic coin detection device has low working efficiency and large outer dimensions, and often needs to be equipped with a turning mechanism, so the structure is relatively complicated and is prone to failure. Contents of the invention [0003] The object of the present invention is to: aim at the shortcomings of the prior art above, to propose a coin double-sided automatic detection device that can simultaneously complete the quality detection of the front and b...
