A method for measuring automatically a user offset value of coating position of coating liquids in a nozzle dispenser and a method for correcting automatically alignment between nozzle dispenser and back glass using the same

摘要

A method for automatically measuring the user offset value of the coating solution in a nozzle dispenser and a method for correcting automatically the alignment between the nozzle dispenser and the back glass using the same are provided to rapidly obtain the user offset value with simple operation. The coating solution is coated on a bare glass(802). The location of the coating beginning edge of the bare glass is detected by using the user offset value measure system(804). The information about the standard of rear side glass and the information of the nozzle dispenser are input to the user offset value measure system(806). The location of the outer ring partition of left and right edge of the rear side glass is detected by using the user offset value measure system(808). The user offset value is computed by using the user offset value measure system(810). The computed user offset value is displayed on the user offset value measure system(812).
