Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, specifically, especially, a kind of multi-specification pipette tip automatic boxing equipment. BACKGROUND

[0002] Pipette is the precise equipment universally applied in laboratory, and its core function is to transfer liquid accurately between containers. The pipette tip is a disposable accessory to ensure the accurate and consistent transfer of liquid in various studies. To avoid cross-contamination, a new pipette tip is needed for each step of liquid handling, and these pipette tips should be placed in a dedicated tip box in order before use. Most laboratories currently use manual boxing method or use a quick mount dispenser to box. Manual boxing is a repetitive and monotonous process that requires technicians to place the pipette tips one by one into the tip box. This method is not only inefficient, but also the pipette tips are prone to accidental falling during operation, which may cause contamination and affect the accuracy and reliability of the experiment. Although the quick mount dispenser is designed to simplify this process, it still requires technicians to perform a series of complex steps. Although this dispenser can theoretically speed up the boxing process, in actual operation, due to the complex operation of adjusting the pipette tips, the time-saving effect is not obvious. In addition, the quick mount dispenser still has the risk of pipette tip falling and contamination. Different sizes of pipette tips require corresponding size of quick mount dispenser, and too many tools increase the complexity of management. This diversity to some extent offsets the convenience brought by the quick mount dispenser.

[0073] This utility model also provides a method for operating a multi-specification pipette tip automatic boxing device, including the following steps:

[0074] S1, in the preparation stage, according to the actual demand to open the cover 702, put different suction heads 209 in the left material bin 101 and the right material bin 104, if the material bin is full, it can not be added; open the front door 703 and put the suction head box 308, and fix it with the clamp 307. Start the power key 606, select the set program on the touch screen display 605, if it is other size suction head 209 and suction head box 308, the parameters can be set according to the size. After setting, start the box loading process.

[0075] S2, the automatic process of box loading is as follows: the translation push rod 210 adjusts the distance between the moving guide groove wall 202 and the fixed guide groove wall 201 according to the size of the selected suction head 209. The translation system 3 moves the suction head box 308 below the falling track 208, so that the hole in the suction head box 308 is directly below the falling track 208; at the same time, the corresponding material bin door opening rudder of the selected suction head 209 is turned, the material bin door is opened, the suction head 209 falls into the guide groove from the material bin, and the material bin door opening rudder is turned to close the material bin door. At this time, part of the suction head 209 enters the guide groove, and part of the suction head 209 scatters in the upper half of the guide groove. The guide groove baffle 207 is adjusted to the closed position, the straight line screw rod motor 203 is started, the guide groove brush 204 is driven to move horizontally from left to right, part of the suction head 209 scattered in the upper half of the guide groove falls into the guide groove, the rest of the suction head 209 not falling into the guide groove is pushed into the right recycling slide 404 by the guide groove brush 204, enters the recycling box 407, and the guide groove brush 204 is reset after moving. The guide groove baffle 207 prevents the suction head 209 in the groove from being pushed out by the guide groove brush 204.

[0076] S3, as shown in Figure 1 and Figure 8 , the recycling process is as follows: the lifting motor 406 drives the lifting platform 408 and the recycling box 407 to rise through the chain wheel and chain set 405, when it rises to the specified height, the lifting motor 406 stops, the recycling box 407 will be tilted under the action of the recycling box limiting rod 402, the suction head 209 in the recycling box 407 falls into the classification slide 409, the classification rudder 411 drives the classification baffle 410 to guide the suction head 209 into the corresponding material bin, after a fixed time, the lifting motor 406 is reversed, the lifting platform 408 returns to the initial position, without the intervention of the recycling box limiting rod 402, the recycling box 407 recovers to the original horizontal state under the action of gravity, and the whole is reset.

[0077] S4, when the material bin door is opened and the horizontal camera 501 cannot detect the suction head 209, the equipment determines that there is no remaining suction head 209 in the material bin, at this time, the recycling process is carried out. When the suction head 209 is still not detected, the system determines that there is no remaining suction head 209, and the touch screen display 605 prompts.

[0078] S5, the guide groove baffle 207 is adjusted to the open gear, the push rod 206 is driven by the push linear guide motor 205 to push the suction head 209 in the guide groove from right to left, at this time, the left horizontal camera 501 monitors the falling of the suction head 209 in real time, and the translation system 3 moves once for every falling suction head 209, so that the next hole position is aligned with the falling track 208. Until the suction head box 308 is filled or there is no suction head 209 in the guide groove.

[0079] S6, if there is no suction head 209 in the guide groove, repeat the above process until the suction head box 308 is filled. The overhead camera 502 detects whether the suction head box 308 is full, if there is a lack, the translation system 3 will align the missing hole position with the falling track 208 for supplement.

[0080] S7, if the suction head box 308 is full, the guide groove baffle 207 is adjusted to the recycling gear, the push rod 206 pushes the remaining suction heads 209 in the guide groove in turn, and the suction heads 209 fall into the recycling box 407 through the left recycling slide 403, and the recycling process is repeated.

[0081] S8, the end stage, open the front door 703, take out the suction head box 308, and close the power key 606.

[0082] In summary, the utility model gives a kind of multi-specification pipette suction head automatic box filling equipment, it liberates operator, also improve the box filling efficiency, and the box filling of suction head has the diversity of selection, with intelligent detection function, with good versatility and interactivity.
