Abstract

The present disclosure provides a spacer particle distribution device used for distributing spacer particles toward a surface of a glass substrate and comprising: a sealed chamber, and a base, a lift pin and multiple adsorption assemblies disposed in the sealed chamber. The adsorption assemblies are disposed correspondingly on four edge regions of the base. Each adsorption assembly is electrified independently to respectively control electrostatic adsorption force of each adsorption assembly.

First claim

What is claimed is:

1. A spacer particle distribution device used for distributing spacer particles on a surface of a glass substrate, the spacer particle distribution device comprising:
a sealed chamber, an inner wall of the sealed chamber is electrified to generate static electricity;
a base located in the sealed chamber, located on a bottom of the sealed chamber and used for bearing the glass substrate;
a lift pin located in the sealed chamber, disposed retractably on a surface of the base and used for lifting the glass substrate; and
multiple adsorption assemblies located in the sealed chamber, disposed correspondingly on edge regions of the base, each adsorption assembly electrified independently to respectively control electrostatic adsorption force of each adsorption assembly;
wherein each adsorption assembly comprises an adsorption plate and an engaging member disposed on a bottom of the adsorption plate, a side of the engaging member is engaged with an edge of the base, an end of the adsorption plate is connected to the engaging member, the adsorption plate comprises two opposite first sides and two opposite second sides;
wherein the adsorption plate is disposed obliquely relative to a corresponding edge of the base, an open angle is formed between the adsorption plate and the corresponding edge of the base, and the open angle faces in a direction of an outside of the edge of the base.

2. The spacer particle distribution device as claimed in claim 1 , wherein an end of the adsorption plate is articulated with an upper side of the engaging member.

3. The spacer particle distribution device as claimed in claim 1 , wherein the adsorption plate and the engaging member are formed by folding a sheet metal.

4. The spacer particle distribution device as claimed in claim 2 , wherein the engaging member comprises an upper engaging plate, a lower engaging plate disposed opposite to the upper engaging plate and a side plate, one of two ends of the upper engaging plate and one of two ends of the lower engaging plate are connected securely by the side plate, the other end of the upper engaging plate is connected to an end portion of the adsorption plate.

5. The spacer particle distribution device as claimed in claim 1 , wherein a nozzle is disposed on an inner top end of the sealed chamber.
