Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[0027] The paste application device 100 of this embodiment, such as figure 1 As shown, it consists of a base 1, a support 2, fixed parts 3A, 3B, movable parts 4A, 4B, a coating head 5, a substrate holding tray 6 on which a substrate 8 is placed, a control part 9, a monitor 11, a keyboard 12 poses.

[0028] In addition, it is assumed that the longitudinal direction of the base 1 is an X-axis, the width direction is a Y-axis, and the height direction (vertical direction) is a Z-axis.

[0029] In addition, in figure 1 Although one application head 5 is shown in the drawing, the paste application device 100 including a plurality of application heads 5 may also be used.

[0030] In addition, on the base 1, an X-axis moving mechanism composed of fixed parts 3A, 3B and movable parts 4A, 4B is provided. The fixed parts 3A, 3B are fixed in the X-axis...

Abstract

PURPOSE: A paste spreading method and a paste spreading apparatus are provided to obtain an excellent accuracy in the coating height of a glass paste by absorbing the difference in the coating height by a difference in nozzle-moving directions. CONSTITUTION: A paste spreading method comprises: a step of setting the correction amount of a nozzle height from a substrate(8) to a nozzle(55a) in every moving direction when the nozzle moves along the circumference of a coating region; a step of correcting the nozzle height in every moving direction with the correction amount depending on the moving direction of the nozzle, and moving the nozzle along the circumference of the region.

Description

technical field [0001] The present invention relates to a paste coating method and a paste coating device for coating a paste on a substrate. Background technique [0002] In the manufacturing process of organic EL (Electro Luminescence, electroluminescent) sheets, the process of bonding sealing glass (sealing glass) on the substrate on which the organic EL element is vapor-deposited is applied on the substrate. Paste) is bonded to the sealing glass, and the glass paste is irradiated with a laser beam to join. [0003] In this process, the height of the glass paste applied on the substrate (coating height) requires high-precision uniformity, so the glass paste is often applied to the substrate by printing. [0004] In the printing method, the glass paste is applied to a substrate through a screen on which a pattern (coating pattern) on which the glass paste is applied is formed, and there is a problem that separate screens need to be prepared for each shape of the coating p...
