Embodiment
In order to solve the problem of prior art, the invention provides a kind of test macro of measuring board, measuring system and vehicle glass, a positioning table wherein is set, described positioning table comprises back up pad and support column; Be provided with in the supporting surface of described back up pad and be the point of fixity that matrix form is arranged; Described support column is arranged on the point of fixity of described back up pad, realizes the fixing of determinand and supports by the feature on the fixing determinand.
Among the present invention, fixing point of fixity position (position in matrix), the fixing support column (highly) of realization character parts of realization character parts all is known on the positioning table, can assemble positioning table digital-to-analogue and determinand digital-to-analogue based on fixed relationship, the fixed position of positioning table and determinand, obtain the assembling digital-to-analogue, like this, make that relative position relation and actual determinand the relative position relation in positioning table of determinand in positioning table is consistent in the assembling digital-to-analogue, and then can determine the one-to-one relationship of each unique point on each unique point of determinand and the digital-to-analogue.This shows that the present invention measures board and need not to calibrate again when measuring, can reduce the time that spends when measuring.
Below in conjunction with specific embodiment, the invention technical scheme is elaborated.
With reference to figure 1, show the synoptic diagram that the present invention measures board one embodiment.Present embodiment describes as an example of the measurement board of vehicle glass example, but the present invention does not limit this, and determinand can also be other objects with three-dimensional structure, measures board and can realize measurement to other three-dimensional structure objects.Present embodiment is measured board and is comprised: positioning table 100 and detector 110.
Wherein, positioning table 100 comprises back up pad 101 and support column 103.
Be provided with in the supporting surface of described back up pad 101 and be the point of fixity 102 that matrix form is arranged.Described point of fixity 102 is used for realizing the location of measuring position.If the spacing of point of fixity 102 is excessive, can reduce to measure the measuring accuracy of board; If the spacing of point of fixity 102 is too small, then increase the manufacture difficulty of back up pad 101, therefore preferably, the spacing between the described point of fixity is positioned at the scope of 5cm * 5cm ~ 15cm * 15cm.
Tester table is used for vehicle glass is measured in the present embodiment, and described back up pad 101 is a square plate, and particularly, described back up pad 101 is of a size of 1m * 1m.The upper surface of described back up pad 101 is supporting surface, is provided with a plurality of point of fixity 102 of arranging according to 15 * 15 matrix in the described supporting surface.
Described support column 103 is arranged on the point of fixity 102 of described back up pad 101, particularly, the bottom of described support column 103 can be provided with the protuberance that the shape and size with described point of fixity 102 are complementary, described support column 103 can by described protuberance be sheathed on realize in the described point of fixity 102 fixing.Because point of fixity 102 is matrix form and arranges, and the position of point of fixity 102 in back up pad 101 fix, so support column 103 can be determined in the position on plane, back up pad 101 place.
Described support column 103 also is used for realizing fixing and support to determinand 104 by the feature on the fixing determinand 104.Need to prove that feature is on the determinand 104, can realizes any parts that determinand 104 is fixed herein.
In the present embodiment, described feature is the fixedly buckle that is positioned at vehicle glass one side, particularly, the top of described support column 103 can be provided with the draw-in groove that the shape and size with described fixedly buckle are complementary, the top of described support column 103 is fixed together by described draw-in groove and described fixedly buckle, because the upper surface of described support column 103 has certain area, can play the effect of supporting described vehicle glass simultaneously.
In the present embodiment, a side of described vehicle glass has three fixedly buckles, correspondingly, is provided with three support columns 103 and is respectively applied to fix with different fixedly buckles, and the realization that three support columns 103 can be comparatively stable is to the support of vehicle glass.But the present invention is not restricted this, as long as support column 103 can be realized the stable support to determinand 104, does not limit the quantity of support column 103.For example: for undersized determinand 104, if support column 103 can be realized the stable support to described determinand 104, measure board a support column 103 can only be set.
As mentioned above, because support column 103 can be determined in the position on plane, back up pad 101 place, thereby the feature that is positioned at the determinand 104 of described support column 103 tops can be determined in the position on plane, back up pad 101 place, simultaneously, because the height of support column 103 also is known, therefore the relative position relation of feature in positioning table 100 of determinand 104 can be known, because feature is a part fixing in the determinand 104, therefore, the relative position relation of determinand 104 in positioning table 100 also can be known.
Because positioning table 100, determinand 104 are the in advance device of design, can be based on the assembling of feature in position, support column 103 and the determinand 104 of support column 103 place point of fixity in matrix, realization is to the assembling of positioning table digital-to-analogue and determinand digital-to-analogue, form the assembling digital-to-analogue, and then can set up and be assemblied in determinand digital-to-analogue in the positioning table digital-to-analogue and the corresponding relation between the actual determinand 104 that is fixed in the positioning table 100 in the assembling digital-to-analogue.
For example: measure in the board, three of vehicle glass fixedly buckle comprise the first fixing fixing fixing buckle of buckle, the 3rd of buckle, second.Three fixed card deduction of points are not fixed on the back up pad 101 by the point of fixity of [10,10] in the matrix on the back up pad, [5,15], [14,3].The height that is used for the support column 103 of fixed vehicle glass is 0.5m.
Correspondingly, in digital-to-analogue, in the back up pad digital-to-analogue [10,10], the support column digital-to-analogue of [5,15], [14,3] point of fixity position assembling 0.5m, afterwards with the vehicle glass digital-to-analogue first fixedly buckle, second fixedly the deduction of points of buckle, the 3rd fixed card be not assemblied in back up pad [10,10], on the point of fixity of [5,15], [14,3].
Take first fixedly buckle, second fixedly buckle, the 3rd fixedly the buckle position as unique point as example, design size is on the back up pad digital-to-analogue [10,10], each fixing size of buckle of the vehicle glass digital-to-analogue on [5,15], [14,3] the fixed point back up pad digital-to-analogue.Physical size is each fixing size of buckle of vehicle glass on [10,10], [5,15], [14,3] fixed point support column 103 on the back up pad 101 that detects of detector 110, this shows, determinand is corresponding one by one in having realized digital-to-analogue and having measured board.
If the measuring accuracy of laser displacement sensor is too high, can increase the cost of measuring board, and if the measuring accuracy of laser displacement sensor is excessively low, then be difficult to reach the measuring accuracy of determinand 104.Because the design accuracy of vehicle glass is generally 0.1mm, in the present embodiment, the measuring accuracy of described laser displacement sensor is positioned at the scope of 0.02mm ~ 0.2mm.
Described laser displacement sensor is with a specific top of highly being fixed in determinand 104, and laser displacement sensor can be measured the spacing between determinand 104 and the laser displacement sensor.Because laser displacement sensor is fixed in the positioning table 100, therefore, can know the position of determinand 104 in positioning table 100 based on described spacing.In the practical application, laser displacement sensor is measured a plurality of unique points on the determinand 104 (characterizing the key measurement point of determinand size), to obtain the physical size of determinand 104.
Below in conjunction with the measurement result of laser displacement sensor, the principle that laser displacement sensor is measured determinand 104 physical sizes describes.With reference to figure 2, show the synoptic diagram of detector measurement result one embodiment of the present invention.This sentences the data instance that determinand 104 shown in Figure 1 is measured along OO ' hatching line.
A, B, C, D, E, F are that determinand 104 is along the unique point of OO ' hatching line among Fig. 2.In the coordinate system shown in Figure 2, the measuring position of horizontal ordinate when to be detector 110 move in the height of distance back up pad 101 is the plane of H, particularly, can obtain by time (time can be obtained by the pulse that driver drives detector 110 moves) and the product of detector 110 translational speeds that detector 110 is measured, but the present invention is not restricted the mode that obtains the measuring position.The ordinate of coordinate system is that unique point is with respect to the height of back up pad 101, spacing h between detector 110 and the unique point because laser displacement sensor is measured, the height (namely obtaining the value of ordinate in the coordinate system) of the relative back up pad 101 of poor H-h acquisition unique point of the spacing h that therefore can be measured by the height H (described height H is certain value) of detector distance back up pad 101 and laser displacement sensor.
As shown in Figure 2, in the scope of 0-A, the laser that laser displacement sensor sends does not also begin to detect determinand 104, and laser displacement sensor is measured is height H between detector 110 and the back up pad 101, so ordinate is 0 on coordinate system.When laser displacement sensor detects the marginal point A of determinand 104, begin to measure the spacing h of determinand 104 between each unique point on the OO ' hatching line and detector 110, for example: with respect to the B point, the spacing h of A point and detector 110 is larger, but because ordinate is H-h in the coordinate system, therefore correspondingly, the ordinate that the ordinate that A is ordered in coordinate system is ordered less than B.Similarly, detector 110 is measured C, D, spacing h corresponding to the several unique points of E, F successively, based on the difference of H and h, and then obtains successively corresponding each unique point of ordinate of unique point of C in the coordinate system, D, E, F and the relative height of back up pad 101.As shown in right in Figure 2, can simulate well the profile of determinand 104 on OO ' hatching line by measuring the data that obtain A, B, C, D, E, F.
Particularly, after measuring the data that obtain A, B, C, D, the several points of E, F, whether the data that corresponding A, B, C, D, E, F are ordered in the described data that can measure by comparator probe 110 and the digital-to-analogue are consistent, judge whether determinand 104 meets design specification.
To sum up, measuring position when moving in the height of distance back up pad 101 is the plane of H based on detector 110, the position of unique point in the XY plane can be obtained, and based on the data that laser displacement sensor measures, unique point can be obtained in the position of Z direction.Thereby realized the three-dimensional measurement to the determinand 104 with spatial structure.
This shows, need only in the plane of certain height mobile to arrive position corresponding to unique point on the determinand 104 based on contactless detector 110, need not to move on the determinand 104 and measure, reduced the measurement distance of detector 110, can further reduce Measuring Time.
