Below with reference to Fig. 1 and Fig. 2, steel slab surface sags and crests pick-up unit provided by the invention and method are described in detail, it is the present invention one optional embodiment, can think that those skilled in the art is in the scope not changing the present invention's spirit and content, can modify to it and polish.
Please refer to Fig. 1, and composition graphs 2, present embodiments provide a kind of steel slab surface sags and crests detection method, in order to detect the slab 4 after flame cleaning, provide laser line generator 1, CCD probe 2 and data handling machine 3;
First, the laser vertical that described laser line generator 1 is penetrated is mapped to described slab 4 surface, forms laser rays on slab 4 surface; Under desirable state, described laser rays should be linearity;
Then, utilize described CCD probe 2 from the photo of the described laser rays of the oblique shooting in the side of described laser rays and near zone thereof, and by this picture transmission in described data handling machine 3; Described CCD probe 2 can be arranged at any side in described laser rays both sides, or multiple CCD probe 2 be placed in described laser rays both sides also can, but not the position at described laser rays two ends;
Finally, described data handling machine 3 judges the sags and crests situation of described steel slab surface according to the bending situation of laser rays in photo.
In the present embodiment, laser line generator device irradiating angle is vertical with steel slab surface, for ensureing the accuracy calculated, wants machinery to ensure when installing laser instrument.
CCD probe 2 and laser line generator 1 combinationally use by the present embodiment, make use of the laser rays that CCD probe 2 pairs of slabs 4 are formed to take, thus the sags and crests situation on described slab 4 surface can be judged by the bending change of laser rays on slab 4, simultaneously, after the concavo-convex vestige formed on slab after considering flame cleaning, its shape is comparatively fixing, only need the simple combination of the CCD probe 2 of the laser line generator 1 and oblique shooting vertically injected just can realize the detection of slab 4 concave-convex surface point, and without using the arrangement of numerous and diverse device, just can achieve and the sags and crests on slab after flame cleaning 4 surface is detected.
When slab 4 surfacing, laser rays is straight line, when surface presentation is uneven, inherently bring bending, corresponding geometric relationship is there is in degree of crook with the situation of slab 4 concave-convex surface, by identifying the information such as the position of the laser rays on slab 4 and shape, the position of steel slab surface can be converted out.In the present embodiment, please refer to Fig. 2, described data handling machine 3 is when judging the sags and crests situation on described slab 4 surface, described photo is provided with a datum line, described datum line overlaps with the ideal laser line of no concave-convex point situation, or be parallel to this theoretical laser rays setting, this datum line can be located at the relevant position of CCD probe, when making photo imaging, described datum line Lock-in is on described photo, also can simulate setting in data handling machine 3, the sags and crests situation of described slab 4 can be obtained by following formula:

2represent the distance of the point on no concave-convex point situation part line to described datum line, and be not 0, so, by 2 distance difference to datum line at (x
1-x
2) sags and crests situation can be calculated equally, that is calculate the relatively protruding or recessed amplitude of this point-to-point transmission.Specifically, in the present embodiment, datum line is as shown in Figure 2 parallel to ideal laser line and arranges, now x
2non-vanishing, with reference to this figure, if when datum line overlaps with ideal laser line, x
2data will be 0, also by the datum line position in figure moved to the right the position of practical laser line situation about obtaining.
In another optional embodiment of the present invention, please refer to Fig. 3,2 on described slab 4 when all existing protruding or recessed, if these 2 distances that are that finally record and described datum line are respectively x
1with x
2, then relatively protruding the or recessed amplitude of 2 also can by this formula h=(x
1-x
2) * tg θ determines.
So, the present embodiment not only determines sags and crests on corresponding slab 4 by the sweep found out on laser rays, on microcosmic, clearly the relative concavo-convex situation between each point and other points clearly can be calculated by the measurement of the range data application with collection and formula, namely by these 2 distance x with corresponding its edges
1with x
2process through quantizing obtains the concrete quantification situation of slab 4 sags and crests, once obtain this quantification situation, just can carry out the process of careful quantification accordingly to slab 4.
The present embodiment additionally provides a kind of sags and crests disposal route of steel slab surface, have employed the steel slab surface sags and crests detection method that the present embodiment provides, and according to point-to-point transmissions different on described slab, relatively protruding or recessed amplitude h carries out corresponding process, described steel slab surface is realized smooth.Method those skilled in the art smooth as specific implementation can obtain some technical schemes apparently; the present embodiment is without the need to carrying out detailed restriction to it; as long as meeting utilizes amplitude h to achieve smooth effect, namely can think that it does not depart from the scope of protection of the invention.
