Technical Field

the invention relates to the technical field of cap opening and closing tools, in particular to an automatic cap opening and closing system for a sample bottle.

Background

With the development of automation technology, the automation of analytical test processes is also increasing, and the first step of all analytical processes is the opening of sample vials. In a process control analysis laboratory, sample bottles come from different sampling posts, in order to prevent the samples from leaking and form cross contamination among the samples, the cover of the sample bottle is required to be screwed down, the opening of the sample bottle is equivalent to manual labor for analysts, the cover of the individual sample bottle is screwed down too much, violent force is required to be used during opening, and the samples are sometimes scattered; in addition, the cover opening structure by adopting a robot is complex and unreliable. Therefore, the automatic cap opener for the sample bottles is an important part for realizing semi-automation and automation of the analysis process.

At present, the beverage industry and the pharmaceutical industry have mature automatic cap openers with high efficiency. But sample bottle decapers have the following special requirements that none of these mature decapers can meet.

1. the cover can not be crossed, namely the cover of the sample bottle A is opened, and an analyst must cover the sample bottle A and can not cover other sample bottles after taking the sample;

2. The purpose of opening the sample bottle is sampling, namely the sample bottle must leave the position of opening the cover after opening the cover, make the upper portion of the sample bottle have sufficient space, in order to facilitate the analyst to take a sample, return to the position of opening the cover to close the cover after sampling and finish, and after the bottle lid of other trades is opened, send to and charge the position in order, no longer send back to the home position;

3. The sample bottle cap opener can only open one sample bottle at a time, and the cap can be closed after the sample is taken, namely the control is required to be convenient;

4. The overall size of the sample bottle cap opener cannot be too large, and the two processes of opening and closing the cap need to be completed at the same position, which is obviously different from the cap openers in other industries.

Above technical requirements, the cap opener is required to be provided with a cap opening and closing mechanism which can reliably clamp the bottle cap and is convenient to operate in the process of opening and closing the cap, and a translation device which has automatic position conversion and is convenient to control, and the cap openers in other industries are not matched with the technical requirements at present, so that the sampling operation of the sample bottle cannot be met.
