[0047] The following describes the working process of a quantitative liquid transfer pipette for ink detection according to a specific embodiment of the present application with reference to the accompanying drawings;

[0048] First, a tube body 240 is threadedly installed on the bottom of the connector 230, and the handle cover 110 is held by the hand, and the hand is placed inside the finger groove 111, and the tube body 240 is moved to the ink;

[0049] Then, the bottom of the tube body 240 is submerged in the ink, and the exhaust fan 260 extracts the air inside the first plug 250. At this time, the first plug 250 has been inserted into the upper part of the connector 230, and the connector 230 extracts the air inside the tube body 240, thereby drawing the ink into the tube body 240.

[0050] Subsequently, when the tube body 240 needs to be cleaned, the lifting end of the first lifting frame 220 removes the first plug 250 from the connector 230, and the sliding end of the first linear guide rail 210 drives the first plug 250 and the second plug 320 to move to the top of the connector 230, and the lifting end of the first lifting frame 220 descends to insert the second plug 320 into the upper part of the connector 230;

Under the action of gravity, the water flows into the inside of the connector 230, and flows along the connector 230 to the inside of the tube body 240, so as to flush the inside of the tube body 240.

[0052] Finally, after rinsing, the lifting end of the first lifting frame 220 removes the second plug 320 from the connecting head 230, and moves the first plug 250 to the top of the connecting head 230 under the movement of the sliding end of the first linear slide rail 210, and inserts the first plug 250 into the upper part of the connecting head 230, and the output end of the hot air component 350 heats the air and transports it to the inside of the first plug 250, and then transports it to the inside of the tube body 240 along the connecting head 230, so as to dry the inside of the tube body 240.

[0064] During the ink testing process, different types of ink need to be aspirated and pipetted, so multiple clean aspiration tubes need to be replaced. In many cases, the aspiration tubes are manually twisted. Over time, the fingers of the workers will become sore, which eventually increases the workload of manually replacing the aspiration tubes.

Since the rotating sleeves 460 and the tubes 240 are limited by the polygonal area, the rotating sleeves 460 can drive the tubes 240 to rotate.

The second lifting frame 420 is lifted to insert the tube 240 connected to the connector 230 into the rotating sleeve 460. The output end of the first motor 450 drives the rotating sleeve 460 to rotate, and the tube 240 is removed from the connector 230. Then, the rotating end of the rotating frame 440 rotates to move another adjacent rotating sleeve 460 to the bottom of the connector 230. The clean tube body 240 is placed inside the rotating sleeve 460 at this time. The rotating sleeve 460 is driven by the output end of the first motor 450 to drive the rotation of the tube body 240, and the clean tube body 240 is threadedly connected to the bottom of the connecting head 230, thereby realizing the replacement of the tube body 240. When it is far away from the bracket 310, the tube body 240 can be replaced manually. Therefore, the used tube body 240 can be placed inside the rotating sleeve 460, and the used tube bodies 240 can be installed one by one at the bottom of the connecting head 230 for cleaning, and replaced one by one. During the entire use process, the output end of the first motor 450 is used to drive the rotation of the rotating sleeve 460 to implement the disassembly and installation between the tube body 240 and the connecting head 230, thereby reducing the finger soreness caused by manual installation, thereby reducing the workload of manually replacing the tube body 240.
