[0058] Example one:

[0059] Step 1: The glue spreader coats the frame sealant on the substrate;

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

[0061] Step 3: Control the imaging device in the alignment inspection machine 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 during this movement, scan the brightness of each position passed; the starting point A and the ending point B should be selected so that the moving direction of the imaging device is parallel to the direction of the glue width; in the alignment detector According to the scanning result of the brightness of the imaging device during this movement, the data analysis device draws as Figure 2B In the curve shown, the abscissa of the curve is the coordinate value of each position point passed by the servo motor (ie, the imaging device) during the movement of the imaging device, and the coordinate value is the coordinate value in the moving direction of the imaging device; the ordinate of the curve The coordinate is the brightness contrast value. The brightness contrast value is the difference between the maximum brightness value and the minimum brightness value in the brightness scanning result of the image device at the corresponding position point; then, determine the brightness in the curve drawn this time Contrast peak, the position point corresponding to the brightness contrast peak is an edge point position of the frame sealant;

[0062] Control the imaging device to move along the straight line between the preset second scanning start point C and the second scanning end point D, and perform brightness scanning on each position point passed during this movement; starting point C The selection of the end point D should make the moving direction of the imaging device parallel to the direction of the glue width, and the four points A, B, C, and D are on the same straight line; the data analysis device in the alignment inspection machine should be based on the imaging device in this time The result of the brightness scan during the movement, drawn as Figure 2B The curve shown; then, determine the peak brightness contrast in the curve drawn this time, and the location point corresponding to the peak brightness contrast is the other edge point of the sealant.

[0063] Then, the glue width of the frame sealing glue is determined according to the position of the two edge points of the frame sealing glue. After the glue width does not meet the preset glue width standard, the glue width detection result is fed back to the frame sealing glue coating equipment. The equipment adjusts its own parameters to adjust the glue width of the subsequent coating frame sealant.
