Abstract
The utility model discloses a quality detecting device for embossing printed matter, which comprises a camera group, a closed lamp box and a camera clamping mechanism, wherein the camera group is mounted above a printed matter to be detected via the camera clamping mechanism; the closed lamp box locates between the camera group and the printed matter to be detected, and has a slot in the middle; and the camera group shoots a printed matter image via the slot. The utility model is characterized in that the camera group includes two left-right symmetrical cameras, the cameras can arbitrarily adjust the shooting angles by the adjusting mechanism on the camera clamping mechanism. Since the technical solution is employed, the shot image has good embossing effect; since the cameras are left-right symmetrical, an image having complementary embossing effects is obtained, thus solving the problem of embossing flaw.
Description
Technical field
The utility model relates to a kind of quality detection device of printed matter, relates in particular to a kind of quality detection device of concave-convex printed product.
Background technology
The quality detection device of existing printed matter, mainly comprise a camera, lamp box and camera clamping mechanism, camera is fixedly installed in the top of detected printed matter by the camera clamping mechanism, and lamp box is provided with slit in the middle of the lamp box between photograph unit and detected printed matter; Camera carries out shooting, collecting by this slit to the printed matter image.
Along with the development of print utility, people have higher requirement to packaging, on color, require bright-coloured, on level, not only need can reflection planes the shade of grey, and need relief level, embossing can make product increase relief level.
But adopt diffusion type light source and only adopt vertical angle to carry out image acquisition because existing pick-up unit is most, therefore for concave-convex printed product, shooting effect is undesirable always, so cause existing quality detection device can't detect the concavo-convex defective of no concave-convex, concavo-convex off normal etc. effectively always.
Summary of the invention
The purpose of this utility model is to provide a kind of quality detection device of concave-convex printed product, the solution that this pick-up unit is practical the problem of concavo-convex imaging, make detecting concavo-convex defective becomes possibility.
The purpose of this utility model is achieved in that
The utility model discloses a kind of quality detection device of concave-convex printed product, comprise photograph unit, closed lamp box and camera clamping mechanism, the photograph unit is installed on the top of detected printed matter by the camera clamping mechanism; Closed lamp box is between photograph unit and printed matter, be provided with slit in the middle of the lamp box, the photograph unit carries out shooting, collecting by this slit to the printed matter image, described photograph unit comprises the camera that two left-right symmetric distribute, the camera clamping mechanism is provided with regulating device, this device of described camera can be adjusted shooting angle arbitrarily, and described regulating device comprises slotted hole that is positioned at camera clamping mechanism both sides and the screw that passes slotted hole, and camera is fixed by screw.
Left-right symmetric is distributed with fluorescent tube and reflecting plate in the described closed lamp box, and the reflecting plate top and bottom all join with lamp box, and the fluorescent tube direct irradiation also shines printed matter surface through baffle reflection simultaneously in printed matter surface.
The utility model is taken the image that obtains and is had extraordinary concave-convex effect owing to adopted above technical scheme, adopts mode of left and right symmetry, takes with two cameras, has obtained complementary concave-convex effect image, and then has solved the problem of concavo-convex defective.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
Referring to Fig. 1, the utility model discloses a kind of quality detection device of concave-convex printed product, comprise the photograph unit, closed lamp box 2 and camera clamping mechanism 6, the photograph unit is installed on the top of detected printed matter 5 by camera clamping mechanism 6, camera 1 in the described photograph unit can be adjusted shooting angle arbitrarily by the regulating device on the camera clamping mechanism 67, regulating device comprises slotted hole that is positioned at camera clamping mechanism both sides and the screw that passes slotted hole, camera is regulated by screw and is fixed, closed lamp box 6 is between photograph unit and printed matter 5, be provided with slit 8 in the middle of the lamp box 2, camera 1 carries out shooting, collecting by 8 pairs of printed matter images of this slit;
Left-right symmetric is distributed with the reflecting plate 3 of fluorescent tube 4 and arc in the closed lamp box 2, reflecting plate 3 top and bottom all join with lamp box 2, fluorescent tube 4 forms the low angle direct light facing to the direction of printed matter 5, the reflected light that direct light is played the jog formation on printed matter 5 is collected by digital camera, fluorescent tube 4 also reflects to form diffused light through reflecting plate 3 simultaneously, shine the surface of printed matter 5, have extraordinary concave-convex effect thereby take the image that obtains; In order to take comprehensive concave-convex effect, the utility model adopts mode of left and right symmetry, takes with two digital cameras 1, has obtained complementary concave-convex effect image, and then has solved the problem that can't detect concavo-convex defective.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (4)
