[0003] The most important thing in the pre-heating link is how to place the glass. The existing pre-heating system uses fixed pins to lift the glass up to a height of several centimeters and heats it in the equipment. However, the temperature change of the pin head is not completely consistent with the ambient temperature change. , so that the PI film at the pin head cannot be pre-cured successfully, and because the pin position is fixed, part of the pin head will be on the AA area (Active Area, effective area) of the glass substrate, resulting in the PI film in the AA area being different from other positions , after encapsulation, the AA area of ​​the screen is prone to bad circular black and white dots, which will lead to the scrapping of the screen

Abstract

The invention provides an intelligent pin bearing device, an intelligent pre-heating bearing system and a substrate heating and placing method, and relates to the technical field of flat plate production. The intelligent pin bearing device comprises a base table, wherein a plurality of adjustable pin mechanisms are arranged on the base table; the top ends of the plurality of adjustable pin mechanisms jointly form a top-supporting plane used for holding a substrate in a top-supporting manner; and the position of the top end of each adjustable pin mechanism is adjustable, so that the top end ofeach adjustable pin mechanism abuts against a protection area. During actual preheating, the substrate is placed on the top-supporting plane, and the top end of each adjustable pin mechanism holds theprotection area of the substrate in a top-supporting mode. Compared with the prior art, the intelligent pin bearing device provided by the invention does not affect the successful pre-curing of a PImold in the preheating process, meanwhile, the quality of a screen cannot be influenced during preheating, and the yield of the screen is greatly improved.

Description

technical field [0001] The invention relates to the technical field of flat panel production, in particular to an intelligent stitch bearing device, an intelligent preheating bearing system and a heating and placing method for a substrate. Background technique [0002] In the production process of the flat panel display industry, the preheating process of glass is after the glass is coated with PI film, so that the PI film can be pre-cured on the glass surface. [0003] The most important thing in the pre-heating link is how to place the glass. The existing pre-heating system uses fixed pins to lift the glass up to a height of several centimeters and heats it in the equipment. However, the temperature change of the pin head is not completely consistent with the ambient temperature change. , so that the PI film at the pin head cannot be pre-cured successfully, and because the pin position is fixed, part of the pin head will be on the AA area (Active Area, effective area) of t...
