- the through hole 128 formed in the cover 127 of the separation disk 120 has a shape corresponding to the shape of the pinhole 146 , and thus the fixing pin ( 181 ) is passed through the pinhole 146 and the through hole 128 , and then the lock bolt 180 is rotated to perform binding of the printed circuit board 140 to the separation disk 120 .
- a fixing groove 129 to which the fixing pin 181 is fixed is formed on the inner surface of the cover 127 , and the fixing groove 129 has a vertical direction with respect to the through hole 128 , so that the through hole ( 128 and the fixing groove 129 may have a ten ( ⁇ ) shape as a whole.
- each configuration Holes for alignment are formed in the , and an alignment pin 180 for alignment is coupled to these holes, thereby constructing a heat-using valve control structure.
- the separation disk 120 is formed with a recessed hole (120h) penetrated in the depth direction from the upper surface, the cover hole (127) of the separation disk 120 so as to correspond to the recessed hole (120h).
- 127h) may be formed.
- a substrate hole 140h may be formed in the printed circuit board 140 to correspond to the cover hole 127h
- an alignment hole 150h may be formed in the pressure plate 150 to correspond to the substrate hole 140h.
- the positions of each component can be precisely aligned. Therefore, the position of the pressing unit 160 with respect to the valve 135 can also be accurately aligned.
- the alignment pin 190 of the present embodiment may have a conical shape in which the lower end 193 is decreased in diameter as it goes down, and thus the lower end 193 is inserted into the recessed hole 120h. And it can be easily inserted into the cover hole (127h) and the substrate hole (140h).
- the central portion 191 of the alignment pin 190 is provided in a cylindrical shape, and a spring 197 is mounted on the outer surface to firmly maintain the position of the pressure plate 150 with respect to the printed circuit board 140 .
- the upper end 195 of the alignment pin 190 has a larger diameter than the alignment hole 150h, and thus the position of the pressure plate 150 can be fixed.
- the upper end 195 of the alignment pin 190 may have a structure detachable from the central portion 191 , and thus, as shown in FIG. 4 , the alignment pin 190 is coupled to the pressure plate 150 . After aligning, the alignment process may be performed.
- the opening and closing operation of the valve 135 is performed by properly transferring heat to the valve 135 provided in the channel 130 connecting the chamber and the chamber of the separation disk 120 . This can be done accurately and smoothly, and thus, the separation operation of the target cells in the separation disk 120 can be reliably performed.
