Abstract
The present invention provides a device for automatically adjusting the uniformity of a showering paint curtain in a transverse direction. Two guide rails in the transverse direction are respectively provided with driving devices moving in the transverse direction and a knife-edge adjusting and driving devices moving in the transverse direction, wherein the driving device moving in the transverse direction is provided with a light detecting device which comprises a light emitter and a light receiver, and the light emitter sends out visible light or invisible light towards the paint curtain. The light receiver receives light permeating the paint curtain, and the light is transmitted to a computer to be processed after the light is converted through an A/D. A mean value worked out is compared with a set thickness value, control signals adjusting a thickness is output, a gap of a knife-edge of the knife-edge adjusting device is adjusted, and sample, calculation and output adjusting signals of the paint curtain are controlled by a program along the whole stroke of the guide rails. The present invention has the advantage that the thickness and the uniformity of the paint curtain in the transverse direction can be automatically adjusted on a production line, and the present invention is not influenced by factors, such as environmental changes, temperature changes, etc.
Description
Technical field
The present invention relates to a kind of in silver mirror glass production line adjusted leaching paint lacquer curtain flow transverse regularity adjusting device and method.
Background technology
A leaching paint opening of silver mirror glass production line flow coating equipment is all fixed at present.When general device is installed or before production, carry out the adjusting of edge of a knife opening horizontal homogeneity, tolerance leaching paint lacquer curtain uniform method is: use a certain size glass plate horizontal each diverse location under the leaching paint head to do towards the curtain leaching paint, the size of weighing weight in wet base successively then, according to the difference of weight in wet base, regulate the edge of a knife set screw of each relevant position.Method is loaded down with trivial details and bothersome, and effect is bad again, and when causing the change of lacquer curtain flow owing to the variation of factors such as temperature in process of production, can't carry out online adjusting.
Summary of the invention
The invention provides a kind of apparatus and method that are used for regulating automatically leaching paint lacquer curtain horizontal homogeneity, on two cross slide waies, be separately installed with horizontal mobile drive deivce and horizontal mobile edge of a knife adjusting drive unit, laterally on the mobile drive deivce, light detection device is installed, light detection device comprises optical transmitting set and optical receiver, optical transmitting set sends visible light or black light to the lacquer curtain, optical receiver receives the light that sees through the lacquer curtain, after the A/D conversion, send Computer Processing, the one-tenth-value thickness 1/10 of calculating average and setting compares, the control signal of thickness is regulated in output, regulate the slit of the edge of a knife for edge of a knife adjusting device, along of the sampling of the whole stroke of guide rail to the lacquer curtain, calculate and output regulation signal, by programme-control;
Laterally mobile drive deivce is made of horizontal removable drive and actuator, the horizontal mobile edge of a knife is regulated drive unit, be made up of edge of a knife adjusting driver and edge of a knife adjusting device, two drivers can drive with driven by motor screw mandrel or belt wheel and move, and two drivers are synchronous operation;
Edge of a knife adjusting device can drive respectively with two 2 stepper motors and compress and pull out adjustment screw, regulates the size in edge of a knife slit;
The control method of control lacquer curtain flow transverse regularity adjusting device the steps include:
A checks horizontal driver are you ready now and got well then next step, otherwise report to the police that program stops;
B checks to regulate driver by the edge of a knife are you ready now and has got well then next step, otherwise report to the police that program stops;
C checks that whether horizontal driver is starting zero-bit, and in this way, then next step otherwise moves to zero point;
D judges whether " stopping " button action, in this way, then stops the effect operation, otherwise, next step;
E gets the full impregnated value outside the lacquer curtain, use for regulating lacquer curtain thickness;
F moves laterally to next sample point;
G, behind sample point, the value record of reading this point is to database;
H judges and whether arrives the horizontal whole process of setting, in this way, then stop value, be not, to next some value;
I calculates the average of this stroke and the difference of each point and setting thickness;
J judges how point needs to adjust, decision positive direction adjustment or adjustment in the other direction;
K turns edge of a knife slit down;
L transfers big edge of a knife slit.
Advantage of the present invention is, can realize regulating the thickness of lacquer curtain and horizontal uniformity automatically on production line, is not subjected to the influence of factors vary such as environment temperature.
