Description

Technical Field

[0001] The invention relates to the technical field of leak detection, and in particular to a BFS leak detection device with an automatic vibration mechanism. Background Art

[0002] Sealed products (such as glass or plastic ampoules, etc.) should be tested for sealing, and the sealing of other packaging containers should be sampled and inspected according to the operating procedures. Therefore, BFS packaging should be tested for sealing. At present, BFS packaging online leak detection adopts BFS packaging online leak detection technology based on the principle of vacuum decay method. This technology is completely non-destructive and does not damage the packaging or the product, which can avoid affecting the stability of the product. It uses imported multiple high-precision detection modules combined with mechanical arms for automatic feeding and unloading. The detection process can be fully automated without manual intervention. For row-by-row BFS packaging, the best detection accuracy can reach 3 microns. It is the current technical means for BFS packaging online leak detection.

[0003] However, during the detection process, most BFS packages are always in a detection state from the initial detection stage to the entire detection process, so it is impossible to detect leaks in other directions. Therefore, the prior art lacks equipment for all-round detection of BFS packages. At the same time, when the BFS package is tipped over, some liquid medicine will accumulate near the top of the BFS package, causing the horizontal position of the detection to be lowered, thereby affecting the detection results.
