Compression head for cathode ray tube exhaust device, exhaust device and exhaust method using same

摘要

Disclosed are a compression head for a cathode ray tube exhaust device, an exhaust device using the same, and an exhaust method. In the compression head according to the present invention, an exhaust hole is formed at a central portion thereof to be connected to a vacuum pump to form an exhaust passage, and a support plate having a groove connected to the exhaust hole to a predetermined depth at an upper end thereof, and a groove of the support plate. An annular sealing ring seated on the annular ring, an annular compression ring provided on the sealing ring to increase the compression effect of the sealing ring, and a hole in which the exhaust pipe is inserted in the center of the compression ring, It is characterized in that it comprises a compression plate for vertically compressing the compression ring and the sealing ring by the lifting and lowering action of the cylinder loader installed on the outside. By changing the shape of the compression head in this way, the number of times of use of the sealing ring can be extended, and the leak between the exhaust pipe and the compression head can be reduced.
