Automated liquid supply mechanism and coater provided with same

Abstract

[Problem] To provide an automated liquid supply mechanism eliminating the need to physically connect a liquid material storage portion and a discharging device and capable of effectively preventing generation and mixing of particles, and a coater provided with the automated liquid supply mechanism. [Solution] An automated liquid supply mechanism characterized by comprising: a liquid storage portion for storing a liquid material; a supply portion having a supply port for supplying the liquid material stored in the liquid storage portion; a receiving portion having a bubble removing mechanism and a receiving port for receiving the liquid material discharged from the supply portion; and a receiving portion driving device for driving the receiving portion, wherein the receiving portion moves to a receiving position with the receiving port located immediately below the supply port, receives the liquid material supplied in drops from the supply port, and supplies, to the discharging device, the liquid material from which bubbles have been removed by the bubble removing mechanism, and a coater provided with the automated liquid supply mechanism.

Description

technical field [0001] The present invention relates to an automatic liquid supply mechanism capable of preventing air bubbles or particles from being mixed into a liquid, and a coating device equipped with the same. Background technique [0002] In the process of manufacturing a liquid crystal display, there is a panel process (also called a cell process) in which two opposing substrates are bonded to form a liquid crystal layer therebetween. In particular, when manufacturing a large-sized panel, a drop injection method in which liquid crystal is dropped onto one substrate before bonding and then bonded is performed. [0003] In the drop injection method, in order to drip the liquid crystal onto the substrate, a device is used that has a container for storing the liquid crystal, and discharges a predetermined amount each time from a nozzle installed in the container by the action of gas pressure or mechanical pressure. the allocator. [0004] In recent years, along with t...

AI Technical Summary

Problems solved by technology

If the size of the substrate increases, the amount of liquid crystal used will also increase, so it becomes difficult to deal with the small storage container (syringe) used in the conventional dispenser

The reason is that the liquid crystal will be used up immediately in a small storage container, and the container needs to be replaced frequently, so the efficiency in terms of productivity and workability will decrease.

In addition, when replacing the storage container, there is also a concern that air bubbles or foreign matter (hereinafter referred to as "particles") may be mixed in
