Description
Technical field
The present invention relates to a kind of image acquisition device that can simultaneously gather bilateral image, particularly a kind of penetration type image acquisition device for the accurate contraposition of two objects.
Background technology
Biconjugate resemble or the range of application of doubling plate technique of counterpoint very extensive, the fields such as such as semiconductor, flat-panel screens, printed circuit board (PCB) all need to implement that biconjugate resembles or doubling plate technique of counterpoint, therefore, each large industry one after another this biconjugate is resembled or doubling plate technique of counterpoint improves, to expect that this biconjugate of raising resembles or the precision of doubling plate technique of counterpoint, thereby shorten the time of accurate contraposition, to reduce manufacturing cost.
At present, the application of doubling plate technique of counterpoint is as described below:
Please refer to shown in Fig. 1, specifically disclose a kind of technology of the auxiliary automatic aligning of image collection that utilizes video vision device, this image collection alignment device 9 includes an image collection assembly 91, one alignment device 92 and a clamp tool 93, this positioning table 92 is in order to carry lower floor's object 94, and this clamp tool 93 utilizes a folder to control end 931 and grasps a upper strata object 95 in negative-pressure adsorption mode, and this parent object 95 is positioned at the top of this lower floor's object 94, again, on this, lower floor's object 95, 94 surface has respectively one group of corresponding alignment mark 951, 941, and this image collection assembly 91 is respectively towards this alignment mark 951, 941.Please refer to shown in Fig. 2 a and 2b, in the time that this image collection alignment device 9 is carried out contraposition, utilize this image collection assembly 91 to gather respectively on this, lower floor's object 95, 94 alignment mark 951, 941 image, the method of coupled computer auxiliary judgment is to judge on this again, lower floor's object 95, the anglec of rotation of 94, horizontal direction and perpendicular to the error of the lengthwise position of horizontal direction, adjust on this by this alignment device 92 and/or clamp tool 93 accordingly, lower floor's object 95, 94 relative position, to utilize this alignment mark 951, 941 make on this, lower floor's object 95, 94 carry out superimposed contraposition and reach the needed precision of manufacturing process.
But, due to this image collection alignment device 9 be directly with this image collection assembly 91 towards this alignment mark 951,941, therefore only having at this upper strata object 95 fully when printing opacity, could utilize the image collection assembly 91 of this image collection alignment device 9 to complete the capture action of this alignment mark 951,941 in the visible area of image collection assembly 91.Therefore, due to the particular restriction of this upper strata object 95 in material, cause this image collection alignment device 9 cannot be widely used in providing the nontransparent material of enough photic zones but still to need to carry out the object (for example: wafer, Printing screen, flexible circuit board etc.) of accurate technique of counterpoint.
Moreover, because industry now develops towards miniature precisionization mostly, also small becoming more meticulous thereupon of the object size that makes to want to carry out contraposition, therefore when the folder that is only slightly larger than this clamp tool 93 when the size of this upper strata object 95 is controlled end 931, not only be difficult to exceed this folder at this upper strata object 95 and control this alignment mark 951 of location mark of end 931, and also cannot set up this image collection assembly 91 to gather the image of this alignment mark 951 in the surrounding of this upper strata object 95.Therefore, this existing image collection alignment device 9 cannot be carried out capture contraposition accurately to the less object of size.
In order further to improve above-mentioned shortcoming, in prior art, also disclose that another kind of biconjugate resembles or doubling plate technique of counterpoint, please refer to shown in Fig. 3 a, another kind of image collection alignment device 8 is disclosed, include several image collection assemblies 81, a pair of bit platform 82 and a universal stage 83, this to bit platform 82 in order to carry lower floor's object 84, these universal stage 83 use are fixing for this upper strata object 85, and this parent object 85 is to being positioned at the top of this lower floor's object 84, on this, lower floor's object 85, 84 surface has respectively the alignment mark 851 of several correspondences, 841, and count image collection assembly 81 respectively towards this alignment mark 851 by this, 841.
Shown in Fig. 3 a, in the time that this image collection alignment device 8 is carried out contraposition, utilize this image collection assembly 81 to gather separately the alignment mark 851,841 of this upper and lower layer object 85,84, carry out the auxiliary operation of image processing and mark coordinate to be sent to computing machine, obtain the existing space potential difference of this upper and lower layer object 85,84 by computing.Please refer to shown in Fig. 3 b, after finishing, auxiliary operation obtains the numerical value of space error compensation, accordingly, to adjust on this by this positioning table 82 and/or universal stage 83, lower floor's object 85, 84 relative position, after accurately adjusting, utilize this universal stage 83 upper strata object 85 to be done to the rotation of 180 degree, make the alignment mark 851 of this upper strata object 85 turn to corresponding with the alignment mark 841 of this lower floor's object 84, then, with this upper strata object 85, this lower floor's object 84 is made to relevant action again, wherein, the compensation of this space error includes horizontal direction, perpendicular to horizontal direction longitudinally and three directions such as rotation.
But, due to this image collection alignment device 8 be treat the space error compensation adjustment of this upper and lower layer object 85,84 after, again this upper strata object 85 is carried out to the rotation of 180 degree, therefore, often easily make this upper and lower layer object 85,84 additionally produce rotation error in the process of rotating, and reduce contraposition precision.
Moreover, the accurate relative position of the several image collection assemblies 81 that set up due to this image collection alignment device 8 is very huge for final aligning accuracy impact, if proofread and correct not good or produce the lax and collision of locking part, cause the 81 position skews of image collection assembly, respectively between this image collection assembly 81, produce the error of relativity by making and affect whole image collection alignment device 8, cause the space error between this upper and lower layer object 85,84 cannot obtain due compensation, and reduce the contraposition precision of 85,84 of this upper and lower layer objects.
