Seal head leakage detection device and method

Abstract

The invention provides a seal head leakage detection device and method. The leakage detection device comprises a main air pipe, a slip mechanism thereof, a branch air pipe and a seal head fixing base. The branch air pipe is fixedly connected with and is communicated with the main air pipe. The seal head fixing base is provided with a seal head semi-finished groove and a branch air pipe ramp therein. By means of the slip mechanism, the main air pipe makes linear and rotary movements relative to the seal head fixing base. The leakage detection method comprises: 1, mounting a seal head to be detected in the seal head semi-finished groove; 2, making the branch air pipe fall into the branch air pipe ramp; 3, enabling sleeve connection of an air outlet end of the branch air pipe and the seal head to be detected; 4, immersing a leakage detection part of the seal head to be detected in water in a water tank; 5, making compressed air go into the main air pipe and observing whether there is bubbles from the seal head. The invention makes it possible to conveniently carry out leakage detection of multiple seal heads at the same time during the same leakage detection operation, thereby greatly improving the seal head leakage detection efficiency and reducing the seal head leakage detection cost.

Description

technical field [0001] The invention relates to the technical field of sealing head leak detection, in particular to a sealing head leak detection device and method. Background technique [0002] For such as figure 1 Shown sealing head 1, it is to be injection-molded by special mold during production, after mold opening, take out such as figure 2 Seal head blank shown. Usually, each sealing head semi-finished product includes the sealing head 1 and the sealing head material support 2 connected together, which requires the operator to separate the sealing head 1 from the sealing head material support 2, such as image 3 As shown, the separated sealing head 1 is a finished sealing head, and the separated sealing head material support 2 is specially treated as leftover material. [0003] Since the sealing head 1 is usually used as a sealing member, its sealing performance depends on whether there is a perforation in the sealing head 1 itself. During the injection molding p...
