Problems solved by technology
[0003] Although this inner airbag assembly can solve the adhesion problem between the airbag and the rubber base plate, and achieve the purpose of quickly changing the airbag, this inner airbag assembly is provided with several grooves on the lower plane of the rubber fixing plate. The existence of the groove, when the airbag works for a certain period of time, the inner surface of the airbag will be cut and thinned by the edge of the groove, which will affect the service life of the airbag

The invention relates to an inner air sac assembly for a flexible printed circuit board vacuum rapid compression machine and a vacuum rapid compression machine applying the inner air sac assembly. Theinner air sac assembly comprises an upper mould frame plate, an air sac mounting plate and an air sac, wherein the side edge of the air sac coats the side edge of the air sac mounting plate, a firstconcave part is formed on one surface, far away from the inner cavity surface of the air sac, of the air sac mounting plate, a plurality of vent holes are formed in the bottom surface of a concave part of the first concave part, a cover plate connected with the first concave part in a sealing manner is arranged on the first concave part, a gas distribution chamber is formed on the cover plate inner bottom surface of the cover plate and the bottom surface of the concave part, an air intake communicated with an air source added outside is formed in the cover plate, a second concave part is formed in one side of the upper mould frame plate, and the air sac mounting plate coating the air sac is arranged in the second concave part. The inner air sac assembly provided by the invention can prolong service life of the air sac.
Description
technical field [0001] The invention relates to an inner airbag component of a flexible circuit printed circuit board vacuum quick press and the vacuum quick press. Background technique [0002] Chinese patent document CN 102806747 discloses an airbag assembly in a flexible printed circuit board vacuum fast press, including a rubber base plate and a rubber fixing plate, which are combined up and down to form a cavity, and the airbag is contained in the cavity. The outer cavity surface of the airbag is closely attached to the smooth surface where the rubber access base plate and the rubber fixing plate are in contact. The rubber access base plate has an air inlet, and the air intake hole is connected to an external pressurized air source. Both the upper plane and the lower plane of the rubber fixing plate have through holes, and the lower plane of the rubber fixing plate has a plurality of grooves. The through hole of the plane acts on the inner cavity surface of the airbag ...
