Paste coating apparatus

Abstract

The invention provides a glue spreader comprising many door moulding flasks reciprocating along one direction and coating head along the long rim direction of door moulding flask. A basal plate is seton platform opposite to the injection nozzle of nozzle installed on the coating head. When glue is sprayed from injection nozzle to basal plate, the relative position of basal plate and nozzle changes. In glue spreader for coating the glue figure of the desired shape on basal plate, a structure performs non-contact feeding using electromagnetic coupling between the feed line linearly set on one side of bench and current-collection core set on one side of door moulding flask, in order to transfer the control signal to moving door moulding flask. A semireflecting mirror is installed betweent the optical communication unit on one side of ground and optical communication unit on one side of movability, in order to receive the signal between the moving elements different from moving direction.

Description

technical field [0001] The present invention relates to a gluing device for coating a desired shape of gluing on a substrate in the manufacturing process of a flat panel. Background technique [0002] As a prior art, as shown in Japanese Unexamined Patent Application Publication No. 2002-346452, a glass substrate is placed on a fixed table, and it is arranged so that the main surface of the glass substrate is movable along the X-axis direction. On the gate frame, the nozzle injection port of the coating head that can move along the YZ axis direction is opposite, and while the glue filled in the glue storage cylinder is sprayed from the injection port to the substrate, the substrate and the nozzle The relative positional relationship of the substrate changes, so that the glue pattern of the desired shape is coated on the substrate. In this Japanese Unexamined Patent Application Publication No. 2002-346452, the size of the glass substrate is increased, the coating range of th...

Problems solved by technology

[0004] As described in the above-mentioned conventional Japanese Patent Laid-Open No. 2002-346452, along with the increase in the size of the substrate, due to the power line, signal line and other electrical harnesses and air pressure piping connected from the fixed external control panel to the door frame Increase, the number of cables following the door frame also increases, so it is not suitable for use in a clean environment due to the wear of the cables or the dust caused by the friction between the cables

[0005] In addition, even if a non-contact power feeding method is used as in JP-A-2001-211501, another movable body that moves on the movable body is provided on the movable body, and power is supplied to the other movable body, and There is no description of the transmission of control signals from the fixed part to multiple movable bodies such as the movable body and the coating head.
