Description

[0002] The BFS product is a small container for containing liquid medicine. During the production and packaging process, a detection equipment is needed to detect the air tightness of the BFS product. The detection method adopted is the positive / negative pressure decay method. The principle is to pressurize or vacuum the sealed cavity formed by the test mold to the target pressure, maintain the pressure for a certain time to measure the pressure decay value, and determine the sealing performance of the BFS product by the pressure decay. The existing test mold is usually composed of an upper mold and a lower mold. The BFS product is placed in the lower mold, and the upper mold and the lower mold are combined to form a cavity for testing. For the mechanical feeding and discharging mode, the grabbing part of the mechanical hand is easy to interfere and collide with the lower mold when feeding the BFS product to the lower mold or taking it away from the lower mold. Therefore, after the upper mold and the lower mold are opened, the upper mold needs to be moved horizontally or the lower mold needs to be moved out before feeding. After the test is completed, the upper mold needs to be moved away or the lower mold needs to be moved out before taking the material.
