Specifically, a typical placement cassette 303a for placing pipette tips is 8 × 12, that is, 12 placement holes are formed in each row, and 8 rows, for example, in this specification, the placement cassette 303a is disposed on a placement frame 303b, and a positioning angle 303b-2 allows the placement cassette 303a to be placed in a uniform placement position, where one row of 12 placement holes of the placement cassette 303a exactly corresponds to a compartment in the guide 302. It should be noted that, in the guide 302, the partition 302c divides the two side baffles 302b into 12 compartments, so that the suction head entering the compartment in the guide 302 can accurately fall into the placing hole of the placing box 303 a. The fixed plate 301c and the movable plate 301d are oppositely arranged, a gap capable of clamping the suction head is formed in the middle, the suction head slides from the feeding track 201, namely, enters the fixed plate 301c and is clamped by the movable plate 301d, the distance between the suction head and the fixed plate 301c can be adjusted along with the position change of the movable plate 301d, the length of the suction head can be 12, and the connecting strip 302a connects the baffle plates 302b on the two sides to the position right below the fixed plate 301c, so that 12 compartments on the baffle plates 302b on the two sides correspond to the positions of the 12. When 12 suction heads are full, the push rod motor 202 acts to block the baffle plate 203 at the end of the feeding track 201 to prevent the suction heads from sliding downwards continuously. Meanwhile, the first motor 301f is operated to drive the crank slider 301e to move the moving plate 301d away, so that the suction heads slide down, and the 12 suction heads fall into the 12 compartments in the baffles 302b on the two sides one by one and then fall into the placing box 303 a. The inclined surfaces arranged on the opposite surfaces of the fixed plate 301c and the moving plate 301d ensure that the suction head can still keep a vertical state when the distance between the fixed plate 301c and the moving plate 301d is continuously enlarged, and then accurately fall into the guide 302. Specifically, a weight sensing switch for detecting the weight may be disposed on the fixing plate 301c, and when the weight reaches 12 suction heads, the push rod motor 202 and the first motor 301f are triggered to operate. A time relay can be arranged, when the first motor 301f acts for a period of time, the suction heads fall into the placing box 303a, the second motor 303d is triggered to act, the guide rail seat 303c is pushed for a distance by the matching of the screw rod 303e and the threaded hole 303b-1, the placing hole which is positioned right below the guide piece 302 on the placing box 303a after being pushed is changed into an empty row from a row which is full of suction heads, and the suction heads sequentially act to be boxed.

It should be noted that the device can be adjusted according to the specification of the placing box 303a to adapt to the placing boxes with various specifications, specifically, the triggering weight of the weight-sensitive switch needs to be adjusted, and the length of the fixed plate 301c, the length of the moving plate 301d, the length of the guide 302, and the number of compartments need to be matched to correspond to each other.
