Description
Affiliated technical field
The utility model relates to a kind of image collecting device, particularly relate to a kind of be used for light path coaxial but the device of IMAQ is carried out in two opposite zones of direction, specifically be meant and be used for such as the reference measurement of full-automatic steel reticulated printing machine steel mesh and circuit board and the image collecting device of printing quality inspection, but its scope of application is not limited to stencil printer, can also be used for element and paste on place system, semiconductor manufacturing, the paper ink printing etc. other need adopt imageing sensor to realize the device of benchmark contraposition or use.
Technical background
In the full-automatic steel reticulated printing machine that adopts the steel mesh typography, tin cream accurately is printed onto on the circuit board, the position that will print on the circuit board accurately need be aimed at the perforate on the steel mesh.The method that the aligning of steel mesh and circuit board generally adopts benchmark to aim at is being done mark in other words on steel mesh and the circuit board, the mark that guarantees to work as both correspondences in processing is on time, and the position that will print on circuit board and the steel mesh is promptly aimed at the perforate on the steel mesh.The simplest benchmark alignment methods is the machinery location, the benchmark of this method is the locating hole of special processing on the circuit board, use one or several cylinder piston mechanism on the printing machine, during the location lance of piston is inserted in the locating hole of PCB to reach the purpose of location.Its shortcoming is that positioning accuracy is poor, and speed is slow, because aperture, the location difference of different PCB, that have even do not have a locating hole, therefore this method adaptation is poor, is difficult to adapt to high density, high production and the high-precision development trend that SMT produces, and this technology progressively is eliminated at present.
Adopt the stencil printer of machine vision technique can realize printing quality inspection in benchmark high-speed, high precision aligning, the printing process simultaneously.As shown in Figure 1, the image collecting device of the stencil printer of the type generally comprises two light sources 59,56 at present, spectroscope 53, speculum 54, an imaging len 57 and an imageing sensor 58, in order to eliminate the phase mutual interference of light path up and down, also add light barrier 52,55 in some device.During work, any one of two light sources 59,56 that is arranged in different level is luminous, light source 59,56 is through spectroscope 53 irradiation steel mesh 50 or circuit boards 51, the reflected back spectroscope 53 then, again through light reflection mirror 54 refractions of optical beam to imaging len 57, imaging on imageing sensor 58 at last, the image of Huo Deing is the stack of circuit board 51 and steel mesh 50 images like this, by analysis image, can draw locating information.Also can control the switch of light source by timesharing, thereby timesharing photographs the image of steel mesh 50 and circuit board 51.The advantage of this method is that light path is simple and cost is low, but image analysis algorithm complexity when gathering image simultaneously, the acquisition time image is then more consuming time, also has ghost image, influences graphical analysis; Adopt in the device of light barrier, can eliminate light path and interfere mutually, but owing to there is mechanical action, sample rate is affected, and the life-span of light barrier is also limited.
