Abstract

The invention provides an electrical removal device, which is characterized in that the electrical removal device of a liquid crystal panel substrate comprises a conveying carrier for carrying and placing a liquid crystal panel substrate and conveying the liquid crystal panel substrate along a direction parallel to a liquid crystal panel substrate plane opposed to an ionizer. The ionizer is configured in a way orthogonal or inclined to the conveying direction. An electrical insulation anti-fall component is equipped in an open part on an open plane of a conductive housing of an ionizer unit and facing the liquid crystal panel substrate side for preventing discharge electrodes composed of metal filaments from falling off by cutting. An electrical removal is performed on the liquid crystal panel substrate by supplying power to an alternating current (AC) discharge current stripped of direct current (DC) by the AC high-voltage power supply of the discharge electrode of the ionizer unit and conveying the liquid crystal panel substrate towards the conveying direction through the flat conveying carrier.

Description

technical field [0001] The present invention relates to a static eliminator for removing electric charge charged on the surface of the liquid crystal panel substrate in a manufacturing process of the liquid crystal panel substrate. Background technique [0002] In various manufacturing processes of liquid crystal panel substrates, electrification accompanying the processing of the liquid crystal panel becomes a major problem. For example, in a rubbing process for forming an alignment film on the surface of a liquid crystal panel substrate, since grooves are formed by rubbing the insulating film with a brush, very large electrification by rubbing occurs. Furthermore, the electric charges charged in this way destroy the circuit of the liquid crystal panel substrate or cause alignment abnormality, causing various problems. [0003] As a countermeasure against such a problem, studies on circuit design and the like are being conducted, but they are not perfect, and it is necessa...
