Description

Automatic cell sorter

The present invention relates to a device used in the packing process of the cell line, and more particularly, to form a new lot by sorting the tested cells by type based on the glass ID. The present invention relates to an automatic cell sorter capable of coping with multiple model cells and automatically performing all operations except storing cassettes by exchanging this information with each other through communication with an upper host.

A general packing process of a cell line will now be described.

First, prior to the packing process, a cell test process is performed in which a cell tester classifies a cell into 18V, 20V, and Q classes according to the type and inspection method.

Cells classified into appropriate grades through the cell inspection process enter a packing process. In this process, IDs on the worksheet and the spot are compared to request information from the host based on the cassette ID and sorted according to the cell ID. After sorting, the lot ID and cell information classified in the upper host are stored.

In detail, the cells and worksheets are first transferred from the cell inspection process. Next, the worksheet and ID are checked by unloading the cells in the cassette one by one. Next, the cassette information is received from the host using the PC. Next, after comparing the data between the worksheet and the PC, the cells are unloaded and sorted by type. Next, after writing the cassette ID on the PC and recording the sorted cell information, new information is stored in the host.

However, the following problems emerged through this process.

First, as the operator directly holds the cell by hand and performs loading and unloading, the product is stressed and the work efficiency is reduced.

Second, since the operator directly typed the cell ID which is the sorting information, there was always a possibility that an error occurred in the work, and the checking operation by the naked eye of the worker increased the fatigue of the worker.

Third, the load on the operator, such as cell ID checking, cell loading and unloading, and cell ID typing, was too heavy, resulting in inefficient work efficiency.

Fourth, as the worker directly handled the glass, it was exposed to static electricity.

Fifth, when cell loading into a cassette by hand, a cassette slit collides with the cell, causing a problem of cell breakage such as crack generation.

Sixth, there is always the possibility of foreign matters caused by manual labor.

Finally, from the process automation point of view, the only manual packing process is a significant negative factor in terms of line-wide automation, and there is always a source of manual data errors.

The present invention has been made to solve the above problems, an object of the present invention is to minimize the load of the operator by automating all operations except the loading and unloading of the cassette in the packing process of the cell line, error by manual labor It is to provide an automatic cell sorting apparatus in which work efficiency can be increased by eliminating the occurrence of the

The automatic cell sorting apparatus according to the present invention provides the following effects.

First, it is possible to automate manual operations, eliminating the need for workers to touch the cell directly, and to install an ionizer to create an environment to prevent static electricity.

Secondly, the cassette is moved by the operator, but by removing the operator's handling of the cell can prevent contamination of foreign matter.

Third, the automatic inspection of the cell ID by the naked eye and typing using the work PC can reduce the fatigue applied to the operator and increase the work efficiency.

Fourth, the entire flow of the line can be automated as communication with the host above is automated on behalf of the existing worker.

Finally, the loading and unloading of cassettes and a little computational work can all be completed, reducing work time and workload compared to the conventional one.
