Baking device and exhaust method thereof

Abstract

The invention provides a baking device and an exhaust method thereof. The baking device comprises an oven, a main exhaust device communicated with the oven and an auxiliary exhaust component close to the upper surface on the peripheral surface of the oven, wherein the auxiliary exhaust component is an exhaust window and comprises multiple exhaust ports sequentially formed around the peripheral surface of the oven; a check curtain clinging to one side surface of the exhaust port and capable of going up and down along one side surface of the exhaust port is arranged on each exhaust port; and moreover, the opening size of each exhaust port can be controlled by controlling the up / down of the check curtain, the airflow in the oven is more free and stable, and the baking process quality and the adaptability of the baking device to different products are improved.

Description

technical field [0001] The invention relates to the technical field of display manufacturing, in particular to a baking device and an exhaust method thereof. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Usually, the liquid crystal display panel consists of a color filter substrate (CF, Color Filter), a thin film transistor substrate (TFT, ThinFilm Transistor), a liquid crystal (LC, Liquid Crystal) sandwiched between the color filter substrate and the thin film transistor substrate, and a sealant frame (Sealant ), the molding process generally includes: the front-end array (Array) process (film, yellow light, etching and stripping)...

AI Technical Summary

Problems solved by technology

[0004] In the production process of flat display devices such as liquid crystal display panels, baking devices are often used to bake components such as glass substrates. Existing baking devices usually include open baking devices and closed baking devices. , among them, the internal restriction of the open baking device is less, the space around the heating device is larger, the air flow has a greater degree of freedom, and is not limited by the space, but because the heating device is basically exposed to the external environment, the heating The harmful sublimates produced are difficult to be effectively controlled, and the leakage of sublimates is prone to occur, causing pollution to the environment and poisoning the surrounding staff

The closed baking device uses a closed oven to surround the entire heating device, so that the entire process is completely carried out in a closed space, which effectively reduces the possibility of sublimation leakage and improves safety. However, because the entire device There is basically no air flow exchange with the outside space. The air flow during heating is completely dependent on its own intake and exhaust system. If the design of the intake and exhaust is not reasonable, the gas cannot be discharged in time, which will easily lead to poor manufacturing process and poor equipment reliability. At the same time, due to Different products produce different exhaust volumes during the baking process. It is often difficult for the same exhaust system to meet the process requirements of many different products, resulting in poor adaptability to different products.
