[0002] Pipette tips are commonly used consumables in biological, chemical and hospital laboratories, and the consumption is extremely large. Currently, pipette tips are manually loaded into the tip box. Therefore, after the work is completed every day, in order to ensure the orderly progress of the next day's work, a large number of tips need to be loaded into the tip box. However, the 10μl and 200μl tips are small in size. In the process of putting the tips into the tip box one by one, it is very inconvenient to take and put them in, and the operation time is long. Therefore, loading the tips every day will consume a lot of manpower and precious time. The most important thing is that when manually loading the tips into the tip box, it is easy to cause certain contamination due to the body touching the tips, which will cause the failure of the experiment. However, there is currently no simple, portable and practical device for loading tips into boxes on the market.

In practical applications, the processing method and material of the tip sieve plate 15 can have different changes to meet relevant needs.

[0030] In this embodiment, the function of the tip screen plate 15 is to enable the pipette tips 16 to be quickly erected and arranged in a regular pattern, such as Figure 2 As shown; during use, the tip sieve plate 15 is at a certain angle to the desktop, and then the bulk pipette tips 16 are placed on the tip sieve plate 15 one after another and the tip sieve plate 15 is gently shaken or vibrated. The tips perpendicular to the tip sieve plate 15 will fall into the holes of the tip sieve plate 15, and the tips that have not fallen into the holes will fall into the tip recovery box; when there are a certain number of pipette tips 16 on the tip sieve plate 15, the angle between the tip sieve plate 15 and the desktop is increased, and the pipette tips 16 will slide to one end of the tip sieve plate 15 due to gravity, thereby achieving a close upright arrangement of the pipette tips 16 on the tip sieve plate 15. In each oblong hole or rectangular hole, the center distance between the closely arranged pipette tips 16 is the outer edge diameter of the pipette tip 16, and then the next step of operation is carried out in conjunction with the clamping and transfer device.

The elastic suction nozzle 14 can have other structures as needed.

[0033] In this embodiment, multiple embedded bases 12 are arranged side by side to form an embedded base module, and 6-15 elastic suction nozzles 14 are installed on each embedded base 12; the number of push plates 5 is the same as the number of embedded bases 12, and multiple push plates 5 form a push plate module, and the number of pins 13 is the same as the number of elastic suction nozzles 14.

[0034] In this embodiment, the two ends of adjacent embedded bases 12 are connected by a first connecting block 3, and a third spring 11 is arranged between adjacent embedded bases 12; the two ends of adjacent push plates 5 are connected by a second connecting block 9, and a second spring 8 is arranged between adjacent push plates 5.
