Description

Technical Field

[0001] The utility model relates to the technical field of food and drug packaging equipment, in particular to a container leak detection device. Background Art

[0002] As Figure 1 and Figure 2 shown, for the high-voltage discharge leak detector on the market at present, for drugs with very little filling volume or very viscous, since there is very little liquid medicine in the container, the two detection electrodes cannot be covered; or because the liquid medicine is very viscous and has poor fluidity, it cannot flow to the vicinity of the detection electrode during detection, resulting in inability to detect. Therefore, there are clear requirements for the filling volume and fluidity of the liquid medicine in the use requirements of the leak detector on the market, and detection cannot be carried out if the value is lower than the required value.

[0003] Chinese patent document CN221325828U discloses an ampoule bottle discharge leak detection device, which uses a bottle conveying screw to drive the ampoule bottle to move along the bottom rail. Through the protrusion arranged in front of the detection electrode and in cooperation with the bottle conveying screw, the bottle head of the ampoule bottle swings, so that the liquid medicine in the bottle body breaks through the bottleneck tension barrier and quickly flows into the bottle head, thereby improving the accuracy of the sealing detection of the bottle head of the ampoule bottle. For the situation where there is very little liquid medicine in the ampoule bottle, even if the liquid medicine can flow from the bottle body into the bottle head, it may still not be able to cover the two detection electrodes; for the situation where the liquid medicine in the bottle is very viscous, the liquid medicine may still not be able to flow from the bottle body into the bottle head, and both of these situations will result in inability to detect. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a container leak detection device with a simple structure that can detect drugs with very little filling volume or very viscous.

[0005] To solve the above technical problem, the utility model adopts the following technical solutions:

[0006] A container leak detection device includes a conveying mechanism for conveying a container, an atomizing component for atomizing the liquid in the container, and a discharge leak detection component for detecting the container after the internal liquid is atomized. The discharge leak detection component includes a first detection electrode corresponding to one end of the container and a second detection electrode corresponding to the other end of the container.

[0007] As a further improvement of the above technical solution: the atomizing component is an ultrasonic generator.

[0008] As a further improvement of the above technical solution: the first detection electrode has a flat plate structure.

[0009] As a further improvement of the above technical solution: the second detection electrode includes a plurality of conical tips.

[0010] As a further improvement of the above technical solution: the conveying mechanism includes a bottom rail for carrying a horizontally placed container and a bottle conveying screw for driving the container to translate.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: in the container leak detection device disclosed by the present utility model, before the discharge leak detection component performs detection, the liquid inside the container is atomized by the atomizing component first. After the liquid is atomized, the formed tiny droplets will fill the inside of the container. The distance between the droplets is very small, and the conductivity under high pressure is close to that of the liquid. For high-voltage discharge detection, it is similar to the inside of the container being filled with liquid. Therefore, it can reliably detect liquids with very little filling or very viscous liquids. The structure is simple and ingenious. Tests show that the detection effect is good; the conveying mechanism only needs to convey the container and does not need to drive the container to swing. Therefore, the structure of the conveying mechanism can be simplified and the cost can be reduced.

[0012] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation part. Brief Description of the Drawings

[0022] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0023] Figures 3 to 4 An embodiment of the container leak detection device of the present utility model is shown. The container leak detection device of this embodiment includes a conveying mechanism 5 for conveying the container 3, an atomizing component 4 for atomizing the liquid in the container 3, and a discharge leak detection assembly for detecting the container 3 after the internal liquid is atomized. The discharge leak detection assembly includes a first detection electrode 1 corresponding to one end of the container 3 and a second detection electrode 2 corresponding to the other end of the container 3. In this embodiment, the container 3 is a medicine bottle, specifically an ampoule bottle.

[0024] For the container leak detection device of this embodiment, before the discharge leak detection assembly performs detection, the atomizing component 4 is first used to atomize the liquid inside the container 3. The tiny droplets formed after the liquid is atomized will fill the inside of the container 3, and the distance between the droplets is very small. The conductivity under high voltage is close to that of the liquid, which is similar to the inside of the container 3 being filled with liquid for high-voltage discharge detection. Therefore, it can reliably detect liquids with very little filling volume or very high viscosity, and the structure is simple and ingenious. Tests show that the detection effect is good; the conveying mechanism 5 only needs to convey the container 3 and does not need to drive the container 3 to swing. Therefore, the structure of the conveying mechanism can be simplified and the cost can be reduced.

[0025] As a preferred embodiment, the atomizing component 4 is an ultrasonic generator. Tests show that the ultrasonic generator can form droplets with a size of 5 - 20 μm of the liquid medicine inside the container 3, and these droplets can fill the internal space of the container 3, thus ensuring the feasibility of discharge detection. Of course, in other embodiments, liquid atomization can also be achieved by other means.

[0026] As a preferred embodiment, the first detection electrode 1 has a flat plate structure. The flat plate structure is adapted to the outer shape of the medicine bottle body, which helps to perform discharge leak detection.

[0027] As a preferred embodiment, the second detection electrode 2 includes a plurality of tapered tips 21. The second detection electrode 2 is provided with a plurality of tapered tips 21, which is adapted to the outer shape of the medicine bottle head and helps to perform discharge leak detection.

[0028] See specifically Figure 5 , as a preferred embodiment, the conveying mechanism 5 includes a bottom rail 51 for carrying the horizontally placed container 3 and a bottle conveying screw 52 for driving the translation of the container 3. The conveying mechanism 5 conveys the container 3 horizontally, which is beneficial to make the liquid atomized and fill the entire container 3, and at the same time facilitates the first detection electrode 1 and the second detection electrode 2 to perform detection from both ends.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention by using the above-disclosed technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
