Realize the control method of an above station synchronous operation with a vision camera
Affiliated technical field the present invention relates to a kind of control method of an above station synchronous operation, and vision camera of especially a kind of usefulness realizes the control method of an above station synchronous operation.
Background technology is at electronics adhesive article manufacture field; The strip of different materials is processed to different shape and size; Each station is to the cross cutting of a shape of strip completion, and the difform glue spare that each station cross cutting goes out is according to certain position relation; Critically be combined with each other, form gluing product at last.
In colored printing; Sometimes need accomplish the printing of multiple color with a plurality of work stations; Each work station prints a kind of color; Need to keep the synchronous operation of precision between the seal roller of every kind of color, ghost image appears in the product that just can avoid printing, and the synchronous operation situation of the situation of multicolour press and adhesive article multiple station die cutter is similar.
Below, be controlled to be example with the synchronous cross cutting of multistation electronics adhesive article and describe.
With die cutter roller strip material is added man-hour; Die cutter roller and smooth roll surface distance are pressed close to and are done relative rotary motion; By rolling cut, strip material is cut into satisfactory shape by the blade edge profiles on the die cutter roller to strip material between die cutter roller and smooth roll, if the material that has finished printing is carried out cross cutting; Then must make the blade edge profiles of die cutter roller accurately corresponding with the profile of printed patterns; The shape that shape that follow-up if desired die cutter roller cuts out and front die cutter roller cut out keeps certain relation, then requires the rotational angle of follow-up die cutter roller to become certain position relation with certain datum mark of processed materials, if the equal diameters of the die cutter roller on each station; And the flower of the blade on each die cutter roller shape is corresponding each other; Then under the synchronous operation state, the shape of the strip material that each die cutting roller cross cutting goes out is accurately corresponding, for die cutter roller being cut out meet the product of craft precision requirement; If deviation appears in the position relation, then need correct the anglec of rotation of die cutter roller.
Adopt the die cutter roller of mechanical phase adjusting module transmission, find that with manual type die cutter roller has deviation after, artificial adjustment phase adjusted axle is adjusted an angle forward or backward, makes die cutter roller devious be remedied to correct position; With controlling the mode of correcting automatically; The phase adjusted axle after the discovery die cutter roller has deviation, is adjusted automatically in the position that cursor reads material marking and reads encoder on the die cutter roller simultaneously; Adjust an angle forward or backward, make die cutter roller devious be remedied to correct position.
Adopt the independent servomechanism of no through-drive mode; Need color mark sensor be installed at each station; Read material marking with color mark sensor; Differentiate the position of encoder on this station servomotor simultaneously, regulate servomotor, make it to adjust forward or backward an angle if physical location and setting value have deviation; Adopt the independent servomechanism of no through-drive mode; If use the vision camera mode to detect the phase relation between actual each layer of glue spare shape; Then need detect each relation of the position between the shape once with vision camera, physical location and setting value are compared at each station according to vision camera; There is deviation then to regulate servomotor, makes it to adjust forward or backward an angle.
Adopt vision camera to detect the true form of each layer adhesive material,, current station is carried out the front and back adjustment according to the variation of position; This control mode is very directly perceived, but because that the material that processes of each station is different, shape is different is different with size, so need a vision camera all be installed at each follow-up station; The accuracy of image recognition is difficult to guarantee; Cost is also very high, and to different strips, different shape and different sizes, the illumination of vision camera need be adopted diverse ways; Lighting system is different; Need often to change, the locate mode of vision camera also need adopt diverse ways, so installation process and debug process all bother.
Summary of the invention is in order to overcome existing multistation cross cutting and to print in the Synchronization Control; Adopt the vision camera detection method, all than the problem of trouble, the present invention provides the control method of an above station synchronous operation of a vision camera realization of a kind of usefulness for the cost that faces height, installation and debugging; This method is through the disposable pattern that reads and measure the cluster solid shape that each station processes; To replace the frequent shape of product that changes of traditional detection and the method for size, make that debugging and installation are also all comparatively simple, owing to only needing a vision camera; Just can be to the controlling of the synchronous operation of an above station, so cost is also low.
The technical solution adopted for the present invention to solve the technical problems is: vision camera of a kind of usefulness realizes the control method of an above station synchronous operation; The blade flower shape of the die cutter roller on each station is corresponding each other; It is characterized in that: a position is selected at a side, both sides, middle part at each die cutter roller; Increase a hemisection blade; Strip material through between die cutter roller and the smooth roll is become the hemisection state by rolling cut, and the colored shape of this hemisection blade is a kind of in horizontal line, vertical line, vertical right-angle side, vertical two limits, vertical four edges, polygon, uncovered polygon and the circle; Strip material is through behind last die cutter roller; The hemisection blade of each die cutter roller goes out flowers in the same position hemisection of strip material, along the strip material direction of advance, and the back of a die cutter roller in the end; A vision camera is installed; Gather this flowers, calculate the vertical and horizontal distance between each horizontal line, up rightness, the center of circle in these flowers, these distances and gauged distance are compared; Calculate the site error of the vertical and horizontal of each station die cutter roller, then each die cutter roller station is vertically adjusted and laterally adjustment.
The invention has the beneficial effects as follows that this synchronous operation control method only needs a vision camera just can the colored shape of cluster solid shape to be differentiated and measure; Owing to be that flowers of solid shape are extracted image; So the lighting system of vision camera and locate mode be relative fixed also; Can accomplish the synchronous operation of multistation with a vision camera, cost is low, and it is convenient to realize.
