Abstract
The utility model discloses a quality detection system for holographic laser stripe packaging material presswork, which is used for carrying out apparent quality testing on laser stripe presswork at an unfixed position. A light-emitting diode (LED) light source and a charge coupled device (CCD) scanning head are asymmetrically arranged at the outer side of a transfer roller of bearing holographic laser stripe paper; a laser light-preventing drive mechanism at least can carry out linear movement and autorotation around the center axis in the plane which passes through a detection point and is vertical to the axis of a transfer roller, and used for adjusting the CCD scanning head, so that the CCD scanning head can collect a clear presswork pattern through a reflected light of the LED light source and can avoid the reflected light of the laser stripe. A simple and efficient detection method is provided aiming at the product of the laser stripe with the unfixed position appearing in the presswork. The printing quality detection can be achieved by low-cost transformation of the traditional quality detection system on the fabrication production line of the presswork.
Description
Technical field
The utility model relates to high quality printing system, is the radium-shine wrappage press quality of a kind of holographic shading amount detection systems specifically.
Background technology
In high-grade packages printing; for the apparent color effect of dazzling of outstanding packaging; conventionally printing adopts radium-shine printable fabric; and be the antifalsification that further improves packaging on this basis; the random asynchronous rule Antiforge that arrange, that have Brand characteristic that plates on radium-shine printable fabric, to improve the protection of enterprise's legitimate interests.But along with the apparent effect of material is complicated, the technology of carrying also needs to improve, and at present for radium-shine class material, owing to being subject to the impact of its surperficial laser effect, image acquisition cannot obtain the more stable data that maybe can represent whole structure, cause quality testing in this respect to never have comparatively effectively detection means and technology of one, especially quality testing is caused to great difficulty as for the printable fabric with poster edge.
Printing operation due to radium-shine shading is not in the end to carry out, prior art cannot be carried out the printed matter printing quality with the radium-shine shading in fixed position not in printing semi-manufacture process, at present final end product quality is due to the not impact of the radium-shine shading of fixed position, cannot automatically complete by equipment, the final quality inspection of a large amount of high quality printing product only has by sampling and has estimated, if radium-shine shading is shielded and will destroy sample pattern in the antithetic quality testing of image, because the unfixing of position appears in radium-shine shading, also cannot get rid of the inconsistent spot in sample pattern by software.
Summary of the invention
Technical problem to be solved in the utility model is at a high speed in enormous quantities in the printed matter production run with the radium-shine shading in fixed position not or to this print product, and the radium-shine wrappage press quality of a kind of holographic shading amount detection systems is provided.
The radium-shine wrappage press quality of described holographic shading amount detection systems, be used for the not apparent mass detection of the radium-shine shading printed matter of fixed position, it is characterized in that: the arranged outside at a transhipment roller of support holographic laser shading printed sheet has LED light source and CCD scanning head, described CCD scanning head is arranged on to be kept away on laser light driving mechanism, the asymmetric both sides that are arranged at check point normal of described LED light source and CCD scanning head, this keep away laser light driving mechanism at least can be in through check point and the plane vertical with transhipment roller axis rectilinear movement and around central shaft autorotation, make CCD scanning head collect the clear pattern of printing and to avoid the reflected light of radium-shine shading by the reflected light of LED light source for adjusting CCD scanning head,
Printing surface one side at the tested paper in described transhipment roller front is equipped with position transducer, and range sensor is equipped with in the rotating shaft of described transhipment roller, for accurately obtaining the position of sample pattern;
Described detection system is provided with controller, drive the drive motor of printed sheet transmission by described controller control rotating speed, for controlling drive motor lower than rated speed half-speed operation in the time CCD scanning head being carried out to pick-up pattern and avoid catoptrical adjustments of radium-shine shading, control drive motor normal operation obtaining after the optimum position of CCD scanning head and/or angle;
The information output of described CCD scanning head is connected respectively to the input end of comparison amplifier after low-pass filter with master sample information, the output terminal of comparison amplifier connects alarm.
As prioritization scheme, described LED light source is arranged on one independently on multidimensional driving mechanism, what described CCD scanning head was installed keep away laser light driving mechanism can be carrying out position and the angular adjustment of 6 degree of freedom, for the pre-adjustment to light source irradiation position and image information collecting position; The mixed lighting light that described LED light source adopts diffused light to be combined with direct light.
