US 2014/0360251 A1 · AIRTIGHT TEST APPARATUS AND AIRTIGHT TEST METHOD USING THE SAME

Abstract

The present invention discloses an airtight test apparatus and an airtight test method using the same for testing an airtight property of a case assembled with a plurality of additional members thereon in which the case has through holes corresponding to the additional members. The airtight test apparatus comprises a base, a top plate and a plurality of sealing members selectively and detachably disposed on the top plate. The top plate is capable of moving towards the base to allow the sealing members to correspondingly seal the through holes. During test, the case is placed on the base to form a gas chamber, an air-extracting is performed for the gas chamber and an air pressure is detected. When the detected air pressure is larger than a predetermined value, the sealing members can be selectively utilized to seal the corresponding through holes for determining which through holes have poor airtight property.

Dependent claims

An airtight test apparatus for testing an airtight property of a case assembled with a first additional member and a second additional member thereon, wherein the case has a first through hole connected to the first additional member and a second through hole connected to the second additional member, comprising:

a base provided for carrying the case and having a air-extracting hole, wherein the case and the base form a gas chamber connected to the air-extracting hole as the case is placed on the base and the gas chamber is capable of exhausting through the air-extracting hole;
a top plate disposed on the base and capable of moving with respect to the base;
a first sealing member selectively and detachably disposed on the top plate, wherein the top plate is capable of moving towards the base as the case is placed on the base to allow the first sealing member to be against the case for sealing the first through hole;
and
a second sealing member selectively and detachably disposed on the top plate, wherein the top plate is capable of moving towards the base as the case is placed on the base to allow the second sealing member to be against the case for sealing the second through hole.

An airtight test method using an airtight test apparatus for testing an airtight property of a case assembled with a first additional member and a second additional member thereon, wherein the case has a first through hole connected to the first additional member and a second through hole connected to the second additional member, wherein the airtight test apparatus comprises a base having an air-extracting hole, a top plate disposed on the base and capable of moving with respect to the base and a first sealing member and a second sealing member selectively and detachably disposed on the top plate, comprising the following steps:

(a) placing the case on the base to allow the case and the base to form a gas chamber connected to the air-extracting hole;
(b) selectively and detachably disposing the first sealing member or the second sealing member on the top plate;
(c) allowing the top plate to move towards the base until the first sealing member or the second sealing member already disposed on the top plate is against the case onto the base for sealing the first through hole or the second through hole;
(d) extracting air from the gas chamber through the air-extracting hole;
and
(e) detecting an air pressure of the gas chamber for determining the airtight property of the case.
