Abstract
Provided are an automatic sampling device and method and, more specifically, are an automatic sampling device and method which automatically remove a lid when collecting a sample in order to analyze the state of a chemical solution (medicinal fluid) and which automatically reverse a sample collection container so that the container can be used after being washed with ultrapure water, and thus the device prevents medicinal fluid contamination caused by the sample collection container, lid, adjacent objects in contact therewith, or space during sampling, without being affected by outside conditions during the sampling, prevents safety accidents such as errors or risk caused by manual work, and is improved so as to increase the reliability of sampling.
Claims27
An automatic sampling device comprising:
- a container standby unit for preparing a plurality of containers before testing, and sequentially rotating the container standby unit to select a container for extracting a sample, wherein
- the container standby unit comprises:
- a rotor for sequentially rotating the containers prepared in the container standby chamber at a predetermined angle;
- a container seating plate which is a plate-shaped member and on which the container for holding a sample solution is seated;
- and
- a rotary motor for rotating the rotor;
- a container transfer unit gripping the container selected by the container standby unit, transferring the container to a sampling chamber, and automatically inverting the container, wherein
- the container transfer unit comprises:
- an adsorption cylinder;
- an adsorption stand for vacuum-adsorbing and moving the container, which is selected from the container standby unit to the sampling chamber according to the operation of the adsorption cylinder;
- and
- an inversion motor for rotating and driving the adsorption stand so as to invert and clean the container or to make the container stand upright to hold a sample solution;
- and
- a lid separation unit automatically opening and closing a lid in the sampling chamber from the container transferred by the container transfer unit;
- wherein
- the lid separation unit comprises:
- a gripper fixing pipe having a lid gripper fixed at an end portion thereof;
- a driving motor having a driving gear gear-coupled to a driven gear attached to the gripper fixing pipe to rotate the gripper fixing pipe;
- a gripper operating cylinder connected to a gripper operating rod mounted inside the gripper fixing pipe to perform a gripping operation of the lid gripper;
- a fixed base formed in the upper machine room and having the driving motor and the gripper operating cylinder mounted therein;
- and
- a base lifting cylinder moving the fixed base vertically.
