Problems solved by technology

[0002] The packaging lamination glass used in traditional liquid crystal flat panel displays (TFT-LCD) is Col orFilter glass, which is different from the cover glass (plain glass) in the AMOLED industry. Therefore, the cleaning and drying process in the AMOLED industry cannot be completely in accordance with the traditional TFT- LCD drying method; the traditional drying speed is only 1500-2500mm / min, which cannot meet the high speed requirement of 3000-6000mm / min

Embodiment Construction

[0015] Such as Figure 1~Figure 3 It is a specific embodiment of the present invention.

[0016] (1) Establish an x-y-z coordinate system: establish an x-y coordinate plane with the cover glass conveying plane as the reference plane, define the forward conveying direction of the glass as the x-axis, and define the conveying plane perpendicular to the conveying direction as the y-axis. At the same time, the z axis is defined as the vertical x-y coordinate plane up.

[0017] (2) The air outlet of the air knife AK is parallel to the x-y plane; it forms an included angle of 37° with the z-axis, that is, the inclination angle is 37°. On the x-y plane, the air knife needs to have an included angle of 60° with the x-axis, that is, the swing angle is 60°.

[0018] (3) The air knife is installed on the cleaning machine according to the installation angle of (2), and at the same time, the air outlet of the air knife (Air Knife) is 2mm away from the glass substrate, that is, Gap=2mm. ...

Abstract

The invention discloses a drying process of a cleaning machine for cover plate glass, and the drying process is characterized in that a transmission plane of the cover plate glass is used as a benchmark surface to establish an x-y-z coordinate system, and an air knife is installed on the cleaning machine in a manner that the air knife forms an inclined angle with the z-axis and a swinging angle with the x-axis, and an air outlet of the air knife is parallel to an x-y coordinate surface; and a distance between the air outlet of the air knife and a glass substrate is adjusted to 2mm to 3mm, and the pressure of the dry compressed air is controlled at 7 to 9kgf / cm<2>. When the cover plate glass passes through the air knife, the cover plate glass can continuously pass through the air knife at a high speed more than 5,000mm / min. The cleaning machine adopting the process can effectively dry the cover plate glass after the cover plate glass is washed by water, so that the drying effect can be enhanced, the production time can be shortened, and the production fluctuation and badness can be reduced.

Description

technical field [0001] The invention relates to a cleaning machine drying method for AMOLED (active matrix organic light emitting diode panel) cover glass. Background technique [0002] The packaging lamination glass used in traditional liquid crystal flat panel displays (TFT-LCD) is Col orFilter glass, which is different from the cover glass (plain glass) in the AMOLED industry. Therefore, the cleaning and drying process in the AMOLED industry cannot be completely in accordance with the traditional TFT- LCD drying method; the traditional drying speed is only 1500-2500mm / min, which cannot meet the high speed requirement of 3000-6000mm / min. With the advancement of technology, a high-efficiency and high-capacity washing machine drying process for AMOLED cover glass is highly anticipated. Contents of the invention [0003] The purpose of the present invention is to provide an AMOLED cover plate glass cleaning machine drying process that can effectively enhance the drying eff...
