Roasting device

Abstract

The invention provides a baking device. The baking device includes a box body, a baking chamber arranged in the box body and at the bottom of the box body, a cooling chamber arranged in the box body and at the top of the box body, and a cooling chamber arranged at the top of the box body. The heat-insulated chamber door on the top of the baking chamber, a plurality of uniformly distributed supporting thimbles arranged in the baking chamber, and a load-carrying device arranged in the box and between the baking chamber and the cooling chamber Mechanism, the baking chamber, carrying mechanism and cooling chamber are separated from each other; when the substrate is baked in the baking chamber to reach the preset baking time, the heat insulation chamber door is opened, and the support thimble is raised Eject the substrate out of the baking chamber and transfer it to the supporting mechanism to be supported by the supporting mechanism. By removing the substrate from the baking chamber and transferring it to the supporting mechanism, over-baking of the substrate can be effectively avoided and the process quality can be guaranteed. , Improve product yield.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a baking device. 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), the middle-stage cell (Cell) process (TFT...

AI Technical Summary

Problems solved by technology

The time required for pre-baking or post-baking is certain. Over-baking or insufficient time will affect the quality of the product and affect the normal progress of the upper and lower processes.

[0005] In addition, in the production process of liquid crystal display panels, each process is closely related to the upstream and downstream, so as long as the equipment abnormality occurs in the upstream or downstream, the entire line will be shut down abnormally. The substrate is placed in the baking chamber, and after the baking is completed, the robot arm will take the substrate out of the baking chamber and transfer it to the cooling chamber for cooling. However, during the daily production process, the robotic arm often stops due to various equipment abnormalities. As a result, the substrate cannot be taken out of the baking chamber in time after the baking chamber finishes baking, resulting in overbaking of the substrate, which affects the process quality and yield
