Description

Automatic sample container emptying and cleaning and drying equipment {APPARATUS FOR AUTOMATIC EMPTYING, CLEANING AND DRYING OF SAMPLE BOTTLE}

The present invention relates to an automatic emptying and washing drying apparatus for a sample container capable of unmanned operation by automatically performing the process of emptying the chemical remaining in the sample container after the chemical analysis has been completed, washing it with pure water, and drying it.

In general, the sample container after the chemical analysis has been completed has dangerous chemicals (chemical solution) remaining in the container, so it is necessary to discard it or empty it for the next sample operation and wash and dry it. Chemicals are artificial substances created by the chemical industry, and are used in various industries such as the semiconductor industry and the pharmaceutical industry. For example, various types of chemicals are used in the semiconductor device production process, and the chemical purity lowers cause defects in the semiconductor device, which greatly affects the production yield.

Therefore, in order to check characteristics such as concentration and components of the chemical, a certain amount of chemical (chemical solution) sample is collected in a container and then an analysis operation is performed. Sampling of these chemicals is performed manually or by a sampling device.

For example, if the manual sampling process is described, the operator opens the cap from the container, places it on the workbench, puts the cleaning solution or the chemical to be sampled into the container before sampling, closes the cap, shakes it, and then opens the cap from the container to clean the cleaning solution. Discard and collect chemical samples in containers. After that, the cap is closed and the container filled with chemicals is collected from the workbench and transported to the chemical analysis site.

After collecting a part of the chemical in the sample container for analysis, the cap is closed and the processing process (emptying, washing, drying) is performed, and then it is put into the sample operation or discarded. It is required that the container and cap containing the sample be cleaned immediately prior to sampling.

The above-mentioned manual container cleaning operation consumes a lot of manpower, and there is a high probability that the operator will be directly exposed to chemicals. In addition, problems such as non-uniformity of cleaning quality occur. Above all, if the residual material left in the container is toxic, it can be fatal to the human body if a safety accident occurs.
