Abstract

The invention belongs to the field of OLED (organic light emitting diode) display technologies, and discloses an intelligent water removal room for OLED (organic light emitting diode) glass substrates. The intelligent water removal room comprises a clean room. A baking furnace and a cooling furnace are arranged in the clean room, the periphery of the baking furnace is closed, a feed furnace door is arranged at the front end of the baking furnace, the rear end of the baking furnace is communicated with the cooling furnace via a transition channel, and a movable isolation furnace door is arranged between the baking furnace and the transition channel, is connected with a control computer and is controlled by the control computer. The intelligent water removal room has the advantages that the clean room and baking and cooling equipment are integrated with each other, accordingly, the production takt can be accelerated, the time can be saved, and the efficiency can be improved; the intelligent water removal room is provided with the control computer, so that the intelligent automation degrees of baking and cooling procedures can be upgraded, and the production quality can be improved; the intelligent water removal room is additionally provided with the transition channel, accordingly, loss of heat in the baking furnace can be decelerated, stable internal temperatures of the baking furnace can be guaranteed, and energy consumption can be reduced; integral baking and cooling operation is carried out in the clean room, so that the cleanliness can be guaranteed in OLED production procedures, and the production quality and efficiency of products further can be guaranteed.

Description

technical field [0001] The invention belongs to the field of OLED display technology, and specifically discloses an intelligent OLED glass substrate dewatering room. Background technique [0002] Organic Light Emitting Diode (OLED) is also known as Organic Laser Display. OLED display technology has the characteristics of self-illumination. It uses very thin organic material coating and glass substrate. When current passes through, these organic materials will emit light. Moreover, the OLED display screen has a large viewing angle and can save power. Now be widely used. During the production process of OLED, there will be many low-temperature baking processes, the main purpose of which is to remove the residual moisture on the glass substrate. In order to meet the process requirements and production cycle, the general low-temperature baking process conditions are: temperature, 200-300°C, time, 30-40min, so that the temperature of the baked glass substrate will be very high,...

AI Technical Summary

Problems solved by technology

The current common baking equipment has the following disadvantages: (1) the baking device is separated from the cooling device, and the equipment occupies a large area of ​​the clean room; (2) the baking and cooling devices are separated, which prolongs the production cycle; (3) the baking The internal temperature of the device and cooling device cannot be measured, which may easily cause insufficient or transitional baking and cooling, and affect the quality of the glass substrate; (4) The degree of intelligence and automation of the entire baking and cooling device is not high, resulting in low production efficiency At the same time, the production of OLED has particularly high requirements on cleanliness. During the entire OLED production process, it needs to be carried out in a clean room. The barrier-free integration of the OLED glass substrate baking and cooling device with the clean room is also not solved by the existing technology. of
