An apparatus for manufacturing a medical diagnostic kit that is easy to select for defects {Apparatus for medical diagnostic kits}

The present invention relates to an apparatus for manufacturing a medical diagnostic kit that can easily select defects. More specifically, it is possible to accurately select an individual sheet corresponding to a defect from among the cut individual sheets, and to manufacture a diagnostic kit using only the individual sheets in good condition. The present invention relates to an apparatus for manufacturing a medical diagnostic kit that facilitates defect selection, so that the reliability of the medical diagnostic kit can be improved.

In general, medical diagnostic kits that can easily diagnose diseases such as hepatitis or AIDS or pregnancy using urine or blood are widely available.

These medical diagnostic kits are made of small-sized individual sheets made of a material such as synthetic resin or paper with a thin thickness, and are used in hospitals by being combined with a case that protects the individual sheets.

Briefly explaining the process of manufacturing the diagnostic kit, it is provided in the original raw state, the sheet fabric is cut at regular intervals and transported individually, and the cut individual sheets are independently screened for defects and good products through vision inspection, Each is discharged through a conveyor belt.

Whether or not the individual sheet is defective is checked by marking the defective area on the fabric when it is initially provided in the original state. Therefore, after cutting the sheet fabric, it is determined whether there is a defect by inspecting whether there is a defect marking on each cut individual sheet.

However, when the defect marking is located close to the cutting boundary, the vision inspection device cannot accurately grasp this part, and even though it is an individual sheet corresponding to the defect, it is mistakenly recognized as a good product, and is manufactured as a diagnostic kit and discharged to the outside.

Then, as shown in FIG. 9 , the transfer finger 320 rotates by 90 degrees around the rotation shaft 310 through the rotation driving unit 330 . At this time, the transfer plate 410 has to stand by at one position so that the sheet fabric attached to the transfer finger 320 in a state rotated 90 degrees can be lifted, but the time at which the transfer plate 410 rises depends on the process situation. may vary. That is, if necessary, the transfer finger 320 first rotates and then comes up to an elevated position so that the sheet fabric may be raised.

When the sheet fabric is placed on the upper portion of the transfer plate 410 in this way, the vision camera 11a moves in the width direction as shown in FIG. 10 while the transfer plate 410 is raised to photograph the sheet fabric. When the vision inspection is completed, the transfer plate 410 descends to the position of the sheet cutting unit 20 through the first cylinder 420 as shown in FIG. 11 , and in this process, the transfer plate passes through the second cylinder. The 410 and the pushing device 440 are brought close to the sheet cutting unit 20 in the direction.

Then, finally, as shown in FIG. 12 , as the pusher bar 441 of the pushing device 440 advances, the sheet fabric passes through the sheet cutting unit 20 and is cut into individual sheets.

Although the present invention has been described above with reference to the above embodiments, it goes without saying that various modifications are possible within the scope of the technical spirit of the present invention.
