The specific embodiment
Below in conjunction with accompanying drawing concrete enforcement of the utility model is further described:
Accompanying drawing 1 is the structured flowchart of the utility model based on the COB molding machine control system of vision location technology, as shown in Figure 1, comprise CCD module, industrial computer central control unit, motion control unit, mobile platform, glue dispensing valve, the image information of described CCD module collection point matrix plate, transferring to the industrial computer central control unit handles, to drive the work of mobile platform, it is substrate point glue that mobile platform drives glue dispensing valve according to the control instruction of the information setting motion control unit after handling.Added spy high detection device in the utility model, visited the high detection device and link to each other with the industrial computer central control unit, the thickness of test point matrix plate can be made and judge the sealing height temporarily exactly the substrate of different-thickness.A CCD module is installed directly over workbench, in the utility model embodiment, adopt industrial camera, in board work, on workbench, directly put the aluminium biscuit box of putting plate well by the operator and carry out the shooting of a full visual field, in the utility model system, above workbench, increase tri coloured lantern, in shooting,, be applicable to the light state of catching of different substrate by the free adjustment tri coloured lantern.By the industrial computer central control unit carry out a moment entirely to the point location process, drive mobile platform again and move and carry out one a sealing pattern.
Mobile platform comprises X, Y, three travel mechanisms of Z, to realize that driving glue dispensing valve moves along X-axis, Y-axis, Z axle three-dimensional, mobile platform also comprises T shape travel mechanism, the move left and right that realizes is to provide the multistation workbench, finish on the station in sealing, can not influence the sealing of another one station, and carry out loading and unloading.The perfect adaptation that realizes intelligence full some identification and positioning system and aluminium biscuit box realizes the direct sealing of aluminium dish blowing, improves the yield and the production efficiency of product comprehensively
Accompanying drawing 2 is the schematic flow sheet of the utility model based on the COB molding machine control system of vision location technology.As shown in Figure 2, may further comprise the steps:
A, read intensity profile, the corner location of standard drawing and analytical standard figure, reading of standard drawing herein is meant at least one identical substrate of putting glue according to quilt, get by artificial screening, wherein intensity profile comprises information such as grey level histogram, average gray, gray scale square, and corner location comprises the information such as position distance between angle point number, the angle point.
B, light source are regulated, and by the adjustment of tri coloured lantern, make by information such as an intensity profile of matrix plate and corner location and can clearly show in CCD.
C, by CCD read in its collection by the image of some matrix plate.
D, CCD gather image and standard drawing contrast, as dissmilarity, illustrate that the gray scale of this substrate and angle point are not inconsistent chalaza glue needs, belong to scrap, should give up, and return step B, and continue next substrate and standard drawing and compare, if similar, execution in step E; Wherein similarly to satisfy following all conditions:
Relative coefficient between the grey level histogram of ⅰ, CCD collection image and the grey level histogram of standard drawing correspondence is less than threshold value 1; Determination methods is:
Wherein γ is the coefficient correlation that X point, Y are ordered in the histogram, the X point is gathered in the image a bit for CCD, the Y point is more pairing with the X point in the standard drawing, N is value repeatedly, and usually, N is more than or equal to 30, if γ is more than or equal to more than or equal to threshold value 1, illustrate that then X point, Y point are uncorrelated, otherwise, then relevant.
ⅱ, CCD gather the gray scale square of forming between the image of image and standard drawing correspondence and are less than or equal to threshold value 2.
The angle point number of ⅲ, CCD collection image equals the angle point number of standard drawing.
ⅳ, CCD gather the difference of relative position between the corresponding angle point of relative position and standard drawing between the angle point of image less than threshold value 3.
Above mentioned threshold value 1, threshold value 2 and threshold value 3 are constant, according to the size of suitable threshold 1 of accuracy selection, threshold value 2 or the threshold value 3 set.
E, match point glue pattern plate are complementary with the some glue pattern plate of resources bank in the utility model system, and match point glue track adds glue speed as soon as possible, if there is not the some glue pattern plate that is complementary, then need make some glue pattern plates again.
F, setting actuation movement mechanism carry out some glue from specified point according to driving instruction driving mobile platform drive glue dispensing valve to specifying anchor point to carry out a glue.
Enter read standard drawing before, do preparation definitely:
Detection has or not the sealing task to exist, if having, then opens task, reads standard drawing and carries out as above step operation; As detect no sealing task and exist, then need a newly-built task, can be called this task naming according to the substrate name of task, also can according to current time etc. to this task naming, because may be sometimes a glue be carried out in the subregion of substrate, so when newly-built task, will set, and the sealing parameter is for example put glue speed, some glue time, some glue height, is stopped the setting of glue time etc. to the glue application region territory.
After finishing a glue, the CCD circle collection is next to be repeated above steps by some matrix plate, finishes until all substrate point glue.
Flow process according to the intelligent COB sealing control system of the utility model embodiment, as long as be placed in substrate on the aluminium biscuit box or be placed directly on the workbench, substrate does not need precision positioning, can reduce operator's working time like this, realizes some glue process quickly and easily.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
