In describing the invention, it is to be understood that term " first ", " second " etc. only for descriptive purposes, and it is not intended that instruction or hint relative importance.In describing the invention, it is necessary to explanation, unless otherwise clearly defined and limited, term " being connected ", " connection " should be interpreted broadly, for instance, it is possible to it is fixing connection, it is also possible to be removably connect, or connect integratedly；Can be mechanically connected, it is also possible to be electrical connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary.For the ordinary skill in the art, it is possible to concrete condition understands above-mentioned term concrete meaning in the present invention.Additionally, it will be appreciated that, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.

As shown in Figure 1, it is shown that the alignment method first embodiment of a kind of product to be measured of the present invention.The alignment method of the product to be measured of this embodiment includes:

Step S10, obtain the marker location information on product to be measured and marker location information preset on crimping jig respectively by single or two cameras；

In the para-position scheme of product to be measured provided by the invention, the type of product to be measured can be configured according to actual needs, for instance, product to be measured can be touch screen product.When the electrical property of touch screen is tested, it is necessary to realize test instrunment and the electrical connection of touch screen product to be measured, accordingly, it would be desirable to product to be measured is carried out para-position.Electrical connection between test instrunment and product to be measured needs to use crimping jig, and crimping jig is fixing relative to product place to be measured after mounting to bit platform, can move up and down along to the Z axis of bit platform place coordinate system.Crimping jig can use probe, it is possible to use FPC (FlexiblePrintedCircuit, FPC), also known as flexible printed circuit board or flex circuit application.

It should be noted that, crimping jig is provided with labelling, mark position on crimping jig is completely the same with the mark position on product to be measured, and namely the mark position on crimping jig is consistent with the distance of the mark position on product to be measured to pin, mark size and shape.Position and the number of the labelling on crimping jig and the labelling on product to be measured can be arranged as the case may be and flexibly, alternatively, product to be measured each side arrange a labelling, and the left and right sides on crimping jig also respectively arranges a labelling.In order to improve aligning accuracy, the mark part on crimping jig and the mark part on product to be measured can use alternatively non-transparent material, and mark part near zone uses light transmissive material.

In the process that product to be measured is carried out para-position, hardware components except include for drive product to be measured to move or rotate to bit platform with for except crimping jig that test instrunment and test product are electrically connected, also need to use the camera for obtaining marker location information, the hardware such as light source for polishing, as shown in Figure 2.In the present embodiment, camera is arranged on above product to be measured and crimping jig, the labelling that can simultaneously view on product to be measured and crimping jig in camera fields of view need to be ensured, by collected by camera image is processed, the marker location information on product to be measured and crimping jig can be obtained respectively.This marker location information can be marked at pixel coordinate point on image (x, y).Light source is arranged on below camera, in order to improve aligning accuracy, the physical length in kind of light source should select the strip source of the maximum mark spacing that length is slightly longer than between two labellings of product to be measured, light source colour can determine according to actual product to be measured, it is ensured that the labelling on product to be measured and crimping jig clearly can show in viewing field of camera.

Specifically, when marker location information preset in the marker location information obtained by single camera on product to be measured and crimping jig, need to add a camera shifting axle, camera shifting axle should ensure that parallel with to the X-axis of bit platform place coordinate system when installing, the direction being driven two the labelling place lines in single camera left and right along product to be measured by preset shifting axle is moved, so that this single camera can get the marker location information on product to be measured and marker location information preset on crimping jig.When marker location information preset in the marker location information obtained by two cameras on product to be measured and crimping jig, the two camera installing space should meet camera it can be seen that labelling on corresponding product to be measured, and namely two viewing field of camera angles to ensure unanimously as far as possible.

Step S20, according to the marker location information on described product to be measured and marker location information preset on described crimping jig, obtain the labelling on described product to be measured and the offset angle between labelling preset on described crimping jig and the relative position deviation in X direction and y direction；

After marker location information preset in the above-mentioned marker location information acquired on product to be measured and crimping jig, the labelling on product to be measured and the offset angle between labelling preset on crimping jig and the relative position deviation in X direction and y direction is calculated according to the marker location information obtained.Specifically, the labelling on product to be measured and the drift angle between labelling preset on crimping jig are first calculated according to the marker location information on product to be measured and marker location information preset on crimping jig, as to the offset angle rotated needed for bit platform.This offset angle is for controlling along center of rotation, bit platform is rotated this offset angle so that labelling place line on the product to be measured labelling place line preset with on crimping jig is parallel.Then the new marker location information on product to be measured is calculated according to offset angle, the middle point coordinates of labelling place line new on product to be measured is calculated further according to the marker location information that marker location information new on product to be measured is preset with on described crimping jig, and the middle point coordinates of labelling place line preset on crimping jig is calculated according to marker location information preset on crimping jig, middle point coordinates according to both calculates the labelling on product to be measured and the relative position deviation in X direction and y direction between labelling preset on crimping jig, following example will be described in more detail.

It should be noted that, due to camera leading screw be not same system to bit platform, therefore the visual field coordinate system at camera place is likely to the platform coordinate system at bit platform place or there is deviation, produces error when angular deviation between the two can cause bit platform is moved.Such as, causing bit platform center of rotation grid deviation rotating calculating error, when carrying out motion compensation, this deviation is taken into account by needs.In order to improve aligning accuracy, before in the marker location information obtained on product to be measured and described crimping jig, preset marker location information carries out calculating accordingly, it is necessary to carry out error analysis process to camera with to the angle between bit platform.Specifically, carry out obtaining image with two cameras, product to be measured is provided with around each one be labeled as example, as shown in Figure 3, for the structural representation that angular deviation between visual field coordinate system and the platform coordinate system to bit platform of viewing field of camera processes, with visual field coordinate system for benchmark, need when there is angle between visual field coordinate system and platform coordinate system to be corrected.The labelling first passing through image shot by camera acquisition upper left the right of crimping jig obtains left labelling coordinate points Z₀(X_z0, Y_z0), right labelling coordinate points Z₁(X_z1, Y_z1), the vector of Z0 Z1 place line should be parallel to the X-axis of visual field coordinate system in theory, by left labelling coordinate points Z₀, right labelling coordinate points Z₁The two coordinate can calculate the angle theta=arctan [(Yz1-Yz0)/(Xz1-Xz0)] between vector and the X-axis of visual field coordinate system of Z0 Z1 place line, it is assumed that Z is left labelling coordinate points Z₀To the distance of initial point, then left labelling coordinate points Z₀Actual parameter for visual field coordinate system isYzz0=Z*sin (Φ-θ).Camera can be found out and to bit platform the two system motion axle angular deviation by correcting, camera or to bit platform synchronous translational, measurement markers point Y coordinate offsets, thus skew can calculate camera and to the angular deviation a=arctan [(Ym1-Ym0)/(Xm1-Xm0)] of kinematic axis between bit platform, existence due to a drift angle, have to through transfer algorithm to reduce bit errors between theoretical coordinate and the platform coordinates of motion, move especially for the platform initial stage, scope is relatively big, and the impact that offset error is brought is also big.

It addition, in order to improve aligning accuracy further, in addition it is also necessary to compensate process to bit platform deflection angle error, as shown in Figure 4, for the present invention structural representation to bit platform deflection angle error compensation.Specifically, in Fig. 4, XOY is para-position platform coordinate system, and XmOmYm is theoretical coordinate system, it is assumed that be (Omx, Omy) to bit platform initial point Om theoretical coordinate, and this initial point Om is the coordinate that design and installation is determined.To bit platform coordinates of motion point K1 (Xmk, Ymk), this is the K1 point coordinate relative to para-position platform coordinate system, now needs unified for K1 point to theoretical coordinate K2 (Xk, Yk).K1 (Xmk, Ymk) it is r for the angle of para-position platform coordinate, Om K1 vector length is K, r=arctan (Ymk/Xmk) can be obtained, K=sqrt (Xmk^2+Ymk^2), known para-position platform coordinate system and theoretical coordinate system angle are a, therefore dXmk=K*cos (r-a) can be obtained, dYmk=K*sin (r-a), adds Om (Omx, Omy) offset coordinates, K (Xk can be obtained, Yk), calculating process should be noted that the sign symbol of r and a, and the sign symbol of r and a is relevant with the definition direction of two coordinate systems.

In Fig. 4, para-position flattened disk parameter is converted the processing method to bit platform kinematic parameter and can is: if above-mentioned deflection angle a is sufficiently small, when motion compensation displacement is little, it is possible to need not convert.But when deflection angle a reaches 1 degree, when motion compensation displacement reaches 5mm, in order to improve the reliability of calculating, it is necessary to adopt conversion to process.Reversely conversion is known for dXmk, dYmk, need to obtain the situation of Xmk, Ymk, it is assumed that the drift angle that dXmk, dYmk are formed is w, then have Xmk=K*cos (w+a), Ymk=K*sin (w+a), Xmk and Ymk are namely actual in bit platform kinematic parameter.Certainly, it is necessary to the concrete value carrying out the set deflection angle of conversion process and motion compensation displacement can be configured according to actual needs.

Step S30, according to described offset angle, and on described X direction and y direction, described product to be measured is carried out para-position by relative position deviation.

The offset angle between labelling preset on the above-mentioned labelling obtained on product to be measured and crimping jig, and after the relative position deviation in X direction and y direction, what control product place to be measured rotates this offset angle to bit platform along center of rotation, the labelling place line making the labelling place line on product to be measured preset with on crimping jig is parallel, and control bit platform drives product to be measured mobile corresponding position in X direction, and/or on y direction, move corresponding relative position deviation, labelling on product to be measured and labelling preset on crimping jig are overlapped, complete this product to be measured is carried out para-position, to carry out next step test job.This X direction and y direction are the X-axis corresponding to para-position platform coordinate system difference and Y-axis set up.

The present embodiment can be applicable to the automatic optics inspection (AutomaticOpticInspection based on capacitive touch screen clear mark, AOI) alignment system, can according to the marker location information on the Image Acquisition touch screen product of collected by camera and marker location information preset on crimping jig, calculate the labelling on touch screen product and deviation in angle between labelling, X-direction and in Y direction on crimping jig, and the system that is supplied to carries out automatic aligning, solve manual and that tool is slow to bit rate, precision is low problem.One camera can be used to add the mode of camera shifting axle, relative to other four orders AOI automatic decimal alignment systems, system constructing is simple, it is easy to mechanical engineering personnel design, install, debugging operations simple, being used as double camera and gather image, save 2 or 3 set camera, camera lens, light sources, hardware cost is substantially reduced.

The embodiment of the present invention obtains the marker location information on product to be measured and marker location information preset on crimping jig respectively by single or two cameras, then the labelling on product to be measured and the offset angle between labelling preset on crimping jig is obtained according to the marker location information obtained, and the relative position deviation in X direction and y direction, product to be measured is carried out para-position.Make to achieve that use is single or two cameras obtain marker location information and product to be measured is carried out para-position, para-position does not need manual operation, automaticity is high, reduce hardware cost and simplify debugging operations process, simultaneously relative to other by tool or visual Manual-alignment, improve product to be measured is carried out automatic aligning efficiency and precision.

Further, as it is shown in figure 5, based on the alignment method first embodiment of above-mentioned product to be measured, it is proposed that alignment method second embodiment of present invention product to be measured, in this embodiment, above-mentioned steps S20 comprises the steps that

Step S21, according to the marker location information on described product to be measured and marker location information preset on described crimping jig, obtain the labelling on described product to be measured and the offset angle between labelling preset on described crimping jig；

In the present embodiment, after marker location information preset in the marker location information obtained on product to be measured and crimping jig, the angle 1 between labelling place line and the viewing field of camera transverse axis on product to be measured is calculated according to the marker location information on product to be measured, and calculate on crimping jig the angle 2 between preset labelling place line and viewing field of camera transverse axis according to marker location information preset on crimping jig, compare by angle 1 and angle 2 being carried out work difference, obtain the labelling on product to be measured and the drift angle between labelling preset on crimping jig, as the labelling on product to be measured and the offset angle between labelling preset on crimping jig.

In the present embodiment, in advance controlling bit platform respectively to the right, the direction such as downward, left-handed, dextrorotation is moved, and after moving into place, obtain labelling initial point, move right after right labelling point, move down after lower labelling point, left-handed after hook marker point, five mark positions such as slice marker point after dextrorotation.By the displacement of bit platform and camera are shot obtain mobile before and mobile after be marked on image location of pixels poor, calculate the image pixel positions of labelling poor and to the ratio between bit platform displacement, as the ratio of the physical distance of movement.Such that it is able to by mark position in the angle rotated and image, calculate the position coordinates to bit platform center of rotation, using calculated center of rotation as default center of rotation.

After being compensated angle, calculate the new marker location information on product to be measured according to this offset angle.Specifically, carry out obtaining image with two cameras, product to be measured is provided with around each one be labeled as example and be described in detail, first carry out coordinate definition, it is assumed that to be positioned at the camera C on the left side₀Position light shaft core position is that zero O sets up two-dimensional direct angle coordinate system, and on crimping jig, the coordinate of left side labelling is F₀(X_f0, Y_f0), on product to be measured, the coordinate of left side labelling is T₀(X_t0, Y_t0), light axle center, the camera C1 position position coordinates being positioned at the right is O', and on crimping jig, the coordinate of right indicia is F₁(X_f1, Y_f1), on product to be measured, the coordinate of right indicia is T₁(X_t1, Y_t1), with the O O' X-axis being coordinate system, at a distance of D between zero O and coordinate O', on crimping jig, the vector of left side labelling and right indicia place line is FM [(X_f0, Y_f0), (D+X_f1, Y_f1)], on product to be measured, the vector of left side labelling and right indicia place line is TM [(X_t0, Y_t0), (D+X_t1, Y_t1)].As shown in Figure 6, definition vector TM center of rotation coordinate S (Xs, Ys), and calculate T respectively₀With S line, T₁With the S line angle for X-axis, center of rotation S (Xs, Ys) coordinate can by above-mentioned to bit platform original coordinates and mobile after coordinate calculate.Fig. 6 can obtain, T₀With S line angle RT0=arctan [(Ys-Yt0)/(Xs-Xt0)], T for X-axis₁With the S line angle RT1=arctan [(Ys-Yt1)/(Xs-Xt1d)] for X-axis, it is noted that Xt1d now should be plus Xt1 coordinate later for D.

Then carrying out the calculating of new marker location information (i.e. new coordinate) on product to be measured, in Fig. 6, the length L of vector T0 TR0 can be expressed as: L=2*L_(S-T0)* sin (DR/2), L_(S-T0)=sqrt [(Xs-Xt0) ^2+ (Ys-Yt0) ^2], vector T0 TR0 can be expressed as the angle of X-axis: RM=pi/2-RT0-DR/2, therefore, dX and dY is respectively as follows: dX=L*cosRM, dY=L*sinRM, it is hereby achieved that TR0 coordinate, after namely rotating, on product to be measured, the coordinate of new left labelling is (X_t0+ dX, Y_t0+ dY), in like manner, it is possible to obtain TR1 coordinate (coordinate of new right labelling), note the sign symbol of dX and dY.

Step S23, according to marker location information preset on the new marker location information on described product to be measured and described crimping jig, calculate the labelling on described product to be measured and the relative position deviation in X direction and y direction between labelling preset on described crimping jig.
