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

A kind of cleaning machine drying process of cover-plate glass

Technical field

The present invention relates to a kind of AMOLED(active matrix organic light-emitting diode (AMOLED) panel) the cleaning machine drying means of cover-plate glass.

Background technology

The encapsulation applying glass that tradition liquid crystal flat panel display (TFT-LCD) uses is Co l orFilter glass, this point is different from the cover-plate glass (plain glass) of AMOLED industry, so AMOLED industry cleaning-drying technique can not be fully according to traditional TFT-LCD drying means; Traditional drying speed is 1500-2500mm/min only, does not reach the high-speed requirement of 3000-6000mm/min.Along with the progress of technology, the cleaning machine drying process of the AMOLED cover-plate glass of the high production capacity of a kind of high efficiency enjoys expectation.

Summary of the invention

The purpose of this invention is to provide a kind of effective enhancing drying effect, shorten the process time, reduce the AMOLED cover-plate glass cleaning machine drying process of the generation of processing procedure fluctuation and fraction defective.

For reaching above purpose, the present invention takes following technical scheme to be achieved:

A kind of cleaning machine drying process of cover-plate glass is characterized in that,

(1) transmit the plane take cover-plate glass and set up the x-y coordinate surface as datum level, the direction that definition glass forwards is the x axle, transmits in the plane and is defined as the y axle perpendicular to direction of transfer; Define simultaneously vertical x-y coordinate surface and upwards be the z axle;

(2) with air knife according to z axle inclination angle greater than 30 ° less than 40 °; Be installed on the cleaning machine less than 70 ° greater than 45 ° with the pivot angle of x axle, wherein, the air knife air outlet is parallel to the x-y coordinate surface;

(3) distance with air knife air outlet and glass substrate is adjusted to 2-3mm, and dried compressed air pressure is controlled at 7-9kgf/cm ²

(4) adjust cover-plate glass and pass through the speed of air knife more than 3000mm/min.

In the above-mentioned technique, described air knife inclination angle is 37 °.Described air knife pivot angle is 60 °.

Advantage of the present invention is, adopt unique air knife (Air Knife) setting angle to be installed on the cleaning machine: the air knife air outlet is parallel to glass substrate simultaneously, when cover-plate glass passes through air knife, can continue to be kept above the above speed of 3000mm/min passes through at a high speed, obvious drying effect, anhydrous stain and the cover-plate glass of dripping can be because of the violent shake of brushing of dried compressed air.

Description of drawings

Fig. 1 is the related x-y-z coordinate system of technique of the present invention.

Fig. 2 is that air knife is at the inclination angle of z direction.

Fig. 3 is that air knife is at the pivot angle of x direction.

The specific embodiment:

Be a specific embodiment of the present invention such as Fig. 1 ~ Fig. 3.

(1) set up the x-y-z coordinate system: transmit the plane take cover-plate glass and set up the x-y coordinate surface as datum level, the direction that definition glass forwards is the x axle, transmits in the plane and is defined as the y axle perpendicular to direction of transfer.Defining simultaneously the z axle is that vertical x-y coordinate surface makes progress.

(2) air knife AK air outlet is parallel to the x-y plane; Be 37 ° of angles with the z axle, namely the inclination angle is 37 °.On the x-y plane, air knife needs and 60 ° at x axle clamp angle, and namely pivot angle is 60 °.

(3) air knife is installed on the cleaning machine according to the setting angle of (2), and air knife (Air Kni fe) air outlet is apart from glass substrate 2mm, i.e. Gap=2mm simultaneously.Dried compressed air (CDA) pressure is controlled at 7 ~ 9kgf/cm ²

(4) the adjustment cover-plate glass is 5000mm/min by the speed of air knife.

Claims (3)

1. the cleaning machine drying process of a cover-plate glass is characterized in that, may further comprise the steps:
