METHOD FOR MANUFACTURING A VACUUM BELLOWS ASSEMBLY

摘要

According to a first embodiment of the present invention, a method for manufacturing a vacuum bellows assembly comprises the steps of: (I) assembling a guide, pin, spring, and stopper to bellows; (II) welding the bellows and the stopper; and (III) inserting the welded bellows in a vacuum chamber, and then press-fitting the pin into a through-hole formed in the stopper so as to maintain the inside of the bellows in a vacuum state, wherein the pin is press-fitted in the through-hole from within the bellows. Thus, by maintaining the inside of bellows in a vacuum state through a simple process such as press-fitting a pin or electron beam welding, workability and yield can be improved.
