The wide image measuring device of glass plate

Technical field

The utility model relates to the wide measurement mechanism of a kind of floatation glass production line tin groove inner glass plate, particularly relates to the wide image measuring device of a kind of glass plate, belongs to glass production line measuring and controlling equipment field.

Background technology

Floatation glass production line tin groove forming section glass tape width and limit portion are stable to be to guarantee the key link of steady production, raising finished product rate completely.Before this, the device that successively adopted distinct methods such as electric pole type, pneumatic type, photo-electric to constitute carries out the wide measurement of tin groove inner glass plate, and it all needs to install corresponding sensor probe and cooling device thereof in molten tin bath inside.Except that molten tin bath operating mode and operations for forming are produced the harmful effect, the life-span is short, reliability is not high, measure dynamic range is the ubiquitous problem of said apparatus for a short time.

Summary of the invention

For overcome the reliability that prior art exists not high, measure deficiencies such as little and life-span of dynamic range is short, the utility model provides a kind of glass plate wide image measuring device, described device is installed on the molten tin bath outside, it is stable and reliable for performance.

The technical scheme that its technical matters that solves the utility model adopts is: portion is provided with view window respectively in molten tin bath banding right and left shoulders, two video cameras are installed in respectively in the outer protection water jacket of left and right sides shoulder view window, video camera is by cable incoming image processor, and image processor connects display and keyboard by cable.Video camera picked-up tin groove inner glass band edge portion area image, limit portion region image signal are handled to generate through image processing system and are superimposed with measuring light target limit portion's image and wide data of plate and the wide control signal of plate: be superimposed with measuring light target limit portion's image and the wide data of plate are shown by display; The wide control signal of plate drives the flashboard electric lifting mechanism through the flashboard control box and regulates the glass metal flow that the change of flashboard aperture enters molten tin bath, and is wide with stable glass sheet.Described image processor comprises the image pick-up card and the D/A transition card that is used for controlled quentity controlled variable is converted to by digital form the 4-20MA form that is used for the input analog picture signal is carried out high-speed figure conversion and buffer memory.The AD HOC of described display comprises image display area, display field and curve display district, and superposition has cursor and cursor respectively on image display area.

The beneficial effects of the utility model are: described measurement mechanism can realize the automatic detection of molten tin bath porch glass band edge portion's width and position and automatically regulate, the generation of major accident such as effectively prevent the molten tin bath tankful, touch on only lightly.The cutting yield rate is improved in stabilized glass bandwidth and position.Its characteristics are mainly reflected in: 1 non-cpntact measurement does not influence inner operating mode of molten tin bath and operations for forming; The wide measurement dynamic range in the 2 monitoring visuals field is big, and is strong to the production run adaptability of different size kind; 3 carry out observing and controlling has the demonstration of Real-time and Dynamic image simultaneously, is convenient to operating personnel and intuitively observes the edges of boards state.

Embodiment

Referring to Fig. 1, the wide image measuring device of glass plate mainly is made of view window (1,4), protection water jacket (2,5), video camera (3,6), display 17, keyboard 18 and image processor 19.Electric lifting mechanism 11 is used for changing flashboard 10 apertures, regulates and enters molten tin bath glass metal flow, and control box 12 is used for operating electric lifting mechanism 11, is the conventional configuration of glass production line, is not described herein.

The molten tin bath right side: view window 1 is installed on the molten tin bath banding 7, and protection water jacket 2 is installed in view window 1 outside, and video camera 1 is fixed in the protection water jacket 2; Molten tin bath left side view window 4, protection water jacket 5, video camera 6 are arranged equally with the right side.The camera coverage scope is shown in monitored area 9.Video camera (3,6) adopts 800X600 black and white area array camera.

The picture signal of video camera (3,6) picked-up is sent into image processor 19 by cable, has the tested area image and the measurement result data of the

cursor

23,24 of indication measurement position to send display 17 to show with AD HOC through Flame Image Process and numerical operation generation superposition; Produce the wide control signal of corresponding plate simultaneously and deliver to control box 12, drive flashboard 10 through electric lifting mechanism 11 and do corresponding lifting, regulate the glass metal flow that flows into molten tin bath and reach the wide purpose of stable glass sheet.The position that keyboard 18 is used for the wide setting value of tablet, controlled variable and
