Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein in figure: 1. firm banking, 2. cross left and right guiding fixed support rectangular, 3. lead up and down fixed mount, 4. for short of the guide support in cross up and down, 5.CCD camera vertical hanging fixed sturcture, 6. support fixed coupling unit, 7. tight joint spare, 8. top disk, 9. rotation light source fixing structure, 10. fixedly arc groove bearing, 12. guide-track grooves of channel-section steel, 11. of die sleeve formula.
Embodiment
As shown in Figure 1, the necessary maintenance level of firm banking 1, about two long crosses, guiding fixed support rectangular 2 is perpendicular with the firm banking 1 of both sides, and will be parallel to each other, and plays main support and load capacity effect on same straight line.Shorter support connector 6 is parallel to each other, and whole mechanism platform is played a supporting role.Whole mechanism platform is realized moving left and right by both sides guide-track groove 12, and distance between adjustable mechanism.
Article two, long rectangular 2 structures of cross left and right guiding fixed support are identical, are all cross spigot nut grooves, are convenient to lay bolt and nut, install and setscrew nut, but can not slide out.Two ends fixedly prevent long cross frame left and right play, bob with top disk 8.Can control the distance of horizontal direction by the fixed mount 3 that leads up and down, guarantee between camera equidistant, and guarantee that the viewing field of camera size makes the phase function capture the width of platform complementaryly, the position of support short the up and down of regulating simultaneously that cross leads up and down makes the focal length between camera and printed matter suitable.Article two, long cross guiding fixed support chute and platform level, firm banking 1 is vertical with platform.
CCD camera vertical hanging fixed sturcture 5 is the self structure designs according to camera, and both sides also have aperture, are convenient to threading, also have clamp device, adopts the bolt of unified standard to fix, and physical dimension is little, low cost of manufacture, and mechanical precision is less demanding.
The rotation light source fixing structure 9 of two die sleeve formulas makes light source control can rotate in certain angle by fixing arc groove bearing 11, between the adjustment light source, distance is optimum distance, utilize the complementation stack of light, guarantee that two light source intersection do not have flickering situation, it is the brightest must making center section, all the other have faint light, but it is enough bright to incide CCD camera light.
The present invention by two bases fix, two microscler cross supporting frames, shorter support connector, both sides guide-track groove etc. form, wherein two microscler cross supporting frames play main support and load capacity effect.Shorter support connector is parallel to each other, and whole mechanism platform is played a supporting role, and for mechanism provides enough rigidity, load capacity makes mechanism of the present invention have the advantages such as high stability, rigidity is large, adjustability is strong.External form according to CCD camera self adopts suspension type to fix, and at motion detection platform at a high speed, guarantees extraneous disturbing factor, its vibration error is reduced as far as possible, and adopt arranging of linear array, allow shooting and light occupy the zone of platform, there is not dash area, do not affect image acquisition.adopt the slip of cross grooved to control corresponding distance, be convenient to guiding movement and fixing, can guarantee that the distance of camera and detection platform is at zone of reasonableness, be kept at an angle and so on light illumination, light source provides illumination for printed matter detects, light incides CCD camera catching range and so on, there is not the shadow region, and guarantee that simultaneously the image frame that obtains is clear, feature is obvious, guarantee that image acquisition is effective, make detection speed be further enhanced, thereby make the color detection accuracy rate, detection speed and minimum detectable defect area all are not less than the requirement of function institute, the detection platform that can be used for high-speed image sampling, expecting to solve high-speed motion provides screen resolution not high situation.Such as the quality problems at the high speed detection printed matter, comprise the defective of point-line-surface, in order in time control rejection rate, improve the yield rate of product.Speed and vibration are maximum to the seizure influence factor of image, can not get the image of high resolution, can't compare with the image of standard, affect the quality testing of printed matter.The present invention can suppress speed and vibrate the impact of the dynamic error of bringing, and guarantees the high stability of mechanism, good mechanical property.
