A kind of fpc pressure holding machine coated with wear-resistant material

Abstract

Disclosed is an FPC pressure-maintaining device coated with a wear-resistant material, comprising a machine frame, and a placement plate for placing an FPC, wherein the machine frame is provided with a downward pressure cylinder, a power output end of the downward pressure cylinder is connected to a pressure-maintaining pressure head, and the pressure-maintaining pressure head comprises a pressure head body. Providing multiple aspiration holes solves the problem of harmful gases dispersed in the air harming the human body, solves the problem of heat dispersion of adjacent elements, and solves the problem of solidifying non-molten parts.

Description

technical field [0001] The invention relates to an FPC pressure holding machine coated with wear-resistant materials. Background technique [0002] The so-called holding pressure refers to the process of binding FPC (flexible circuit board) on the LCD surface in the automatic production process of LCD, which needs to be held by a high-temperature holding pressure head. The traditional pressure-holding indenter used for this kind of pressure-holding is an ordinary solid head, and then the indenter is heated by heating, and then the FPC is pressure-holding. During the pressure holding process, it is often found that when the FPC made of solidified aerobic material is heated and held for pressure, three problems will occur. 1. Poor firmness. It is found in the research that due to the lack of air flow in the pressure head part during the pressure holding, the non-melting parts will melt slightly during the pressure holding, resulting in a low yield rate. 2. Since the pressure...

AI Technical Summary

Problems solved by technology

1. Poor firmness. It is found in the research that due to the lack of air flow in the pressure head part during the pressure holding, the non-melting parts will melt slightly during the pressure holding, resulting in a low yield rate

2. Since the pressure head is very hot, the air around it is also very hot when maintaining the pressure, resulting in more or less damage to other nearby components

3. The irritating gas is produced due to the melting of the material. Since the pressure keeping is done in the clean room, this situation will affect the health of the operators.
