Embodiment 1

[0059] Step 1: The glue applicator applies the sealant on the substrate;

[0060] Step 2: The thermal curing furnace cures the frame sealant coated on the substrate;

[0061] Step 3: Control the image device in the alignment detector to move along the line between the preset first scanning start point A and the first scanning end point B under the drive of the servo motor, such as Figure 2A As shown, and scan the brightness of each passing position during this movement; the selection of the starting point A and the ending point B should make the moving direction of the imaging device parallel to the direction of the glue width; According to the brightness scanning results of the imaging device during this movement, the data analysis device draws a graph as Figure 2B As shown in the curve, the abscissa of the curve is the coordinate value of each position point passed by the servo motor (ie, the image device) during the movement of the image device, and the coordinate value ...

Abstract

The embodiment of the invention discloses a frame sealing glue width detecting method, a frame sealing glue width detecting system and frame sealing glue width detecting equipment, which relate to the technical field of liquid crystal display and are used for improving the timeliness of the frame sealing glue drying width detection. According to the method, the system and the equipment, frame sealing glue is coated on a base plate, the frame sealing glue coated on the base plate is subjected to the curing treatment, the glue width of the frame sealing glue subjected to the curing treatment is detected, and in addition, glue width detecting results are output, and the base plate is cut according to the frame sealing glue coated on the base plate. When the method, the system and the equipment are adopted, the timeliness of the frame sealing glue drying width detection is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method, system and equipment for detecting the width of sealing glue. Background technique [0002] With the advancement of technology, liquid crystal displays (Liquid Crystal Display, LCD) have become mainstream products in the display field. In the production process, liquid crystal displays can be formed by combining array (Array) substrates and color filter (CF) substrates. [0003] The box forming process includes the following main processes: frame sealant coating, curing, alignment detection, cutting process, and frame sealant width detection. Among them, the coating of the sealing glue means that the glue machine applies the sealing glue on the substrate to play the role of bonding and sealing; curing means that the heat curing furnace hardens the sealing glue by means of heating; Detection refers to the alignment detection machine to check whether the a...
