Abstract
A lamp air exhausting apparatus is disclosed, which comprises a compression head, a holding assembly, and a securing member. The holding assembly comprises a holder, a flexible tube, a push rod, an eccentric cam and a spring. According to the present invention, a separate exhausting tube is not required, and an electrode can be accurately placed at the center of the lamp.
Claims17
A lamp air exhausting apparatus for sealing a lamp after exhausting air from the interior of said lamp in order to maintain the interior of said lamp in a vacuum, said apparatus comprising:
- a compression head having a hole in which an open end of a lamp can be inserted, said compression head being connected to a vacuum system so as to exhaust the air from the interior of said lamp;
- a holding means for holding a lead of an electrode so that the lead of the electrode passes through the open end of the lamp and said electrode is disposed at the center of said lamp;
- securing means for securing said holding means so that the holding means extends laterally at one side of said compression head;
- and
- said holding means comprising a movable member having a first position in which said lead can be inserted into said holding means and a second position in which said lead is clamped and held in said holding means.
Apparatus for securing a lead and electrode in a vacuum lamp comprising:
- a compression head having an opening to receive a lamp into which an electrode on an electrode lead is to be inserted and the lamp exhausted, said compression head being connectable to a vacuum source;
- holding means connected to said head for receiving and holding the electrode lead which is inserted into said head through said opening before the lamp is connected into said opening;
- means accessible from outside said compression head for operating said holding means to clamp the electrode lead in a position in which when the lamp is placed in said opening, said electrode and said electrode lead will be centered in said lamp;
- and
- resilient means in said head for resiliently engaging said lamp to hold the same secure in said opening and seal the lamp from ambient atmosphere.
A method of inserting an electrode lead and an electrode into a lamp and evacuating the lamp comprising:
- inserting an electrode lead through a hole in a compression head into a holder;
- holder the electrode lead in said holder with an electrode on said lead;
- displacing a push rod in said holder to clamp the electrode lead laterally in a determined position relative to said hole;
- inserting a lamp to be evacuated and sealed into said hole while said lamp receives said electrode and said electrode lead centrally therein due to said determined position of the holder relative to said hole;
- sealing said lamp in said compression head;
- and
- evacuating said lamp by applying vacuum to said compression head.
