Description

Technical Field

[0001] This invention relates to the field of enzyme-labeled plate cleaning technology, and more particularly to a 96-well enzyme-labeled plate washing device. Background Technology

[0002] Currently, there are generally two methods for washing plates in ELISA assays in laboratories. One is the traditional manual washing method, which involves inserting a multi-channel pipette tip, aspirating liquid, injecting it into the ELISA plate, draining the liquid, and patting it dry. This process is repeated until the required number of washes is completed. This method is slow and laborious when washing a large number of plates. The other method is automated washing using an ELISA plate washer. The prepared washing solution is poured into a washing bottle, the washing program is set, and the washing solution is injected into the ELISA plate through a washing tube and a washing head. The plate is shaken to mix, the washing head is inserted into the ELISA plate, and waste liquid is aspirated and discharged into a waste bottle through a waste liquid tube. This process is repeated until the required number of washes is completed. This method of washing plates is fast and labor-saving, but changing the washing solution is relatively troublesome. This is because the washing solution bottle of the enzyme-labeled plate washer is directly connected to the washing head through the washing solution hose, and the washing head directly sucks the waste liquid into the waste liquid tank through the waste liquid hose. When it is necessary to change the washing solution, the washing solution bottle and washing solution hose need to be thoroughly cleaned with clean water, which poses a risk of incomplete cleaning and takes a long time.

[0017] The first moving mechanism 4 includes a moving plate 41, on both sides of which a moving block 42 is fixedly installed. The moving block 42 is slidably installed in the corresponding first guide strip 3. The bottom of the moving plate 41 is provided with a mounting groove 43, and a fixed plate 44 is slidably installed in the mounting groove 43.

[0025] The working principle of the 96-well enzyme-labeled plate washing device provided by this invention is as follows: When cleaning a 96-well microplate is required, first, install the 96-well microplate on the microplate stand 15. Then, move the hydraulic cylinder 8, connecting plate 9, and connector 10 using the first moving mechanism 4 and the second moving mechanism 6, moving connector 10 to directly above the clean pipette tip box 13. Next, move the connecting plate 9 and connector 10 downwards using the hydraulic cylinder 8, inserting connector 10 into the pipette tip 5 inside the clean pipette tip box 13. Then, reverse the hydraulic cylinder 8 to remove the pipette tip 5 from the clean pipette tip box 13. Then, move connector 10 with the pipette tip 5 inserted to directly above the washing solution tank 12 using the first moving mechanism 4 and the second moving mechanism 6. Then, activate the hydraulic cylinder 8 to insert the pipette tip 5 into the washing solution tank 12. Finally, activate the air pump 17 to draw the cleaning solution from the washing solution tank 12 into the pipette tip 5. The first moving mechanism 4, the second moving mechanism 6, and the hydraulic cylinder 8 move the pipette tip 5, which has been sucking up the cleaning solution, to the top of the ELISA plate platform 15. Then, the air pump 17 pumps the cleaning solution into the 96-well ELISA plate on the ELISA plate platform 15 that needs to be cleaned. Then, the shaking device 14 is started to shake the 96-well ELISA plate to mix it. After that, the solution is manually poured out and patted dry. Then, the above operation is repeated several times until the plate is cleaned. The first moving mechanism 4, the second moving mechanism 6, and the hydraulic cylinder 8 are started to move the used pipette tip to the top of the waste pipette tip container 16. Then, the electromagnet 18 is de-energized, and the electromagnet 18 loses its magnetism. Under the action of gravity, the iron ring 19 strikes the used pipette tip 5, thereby removing the used pipette tip 5 from the connector 10, thus completing the collection of waste pipette tips and the cleaning of the 96-well ELISA plate.

[0026] Compared with related technologies, the 96-well enzyme-labeled plate washing device provided by the present invention has the following advantages: This invention provides a 96-well enzyme-labeled plate washing device. Through a first moving mechanism 4 consisting of a moving plate 41, a moving block 42, a mounting groove 43, a fixed plate 44, a sliding groove 45, a slider 46, a first motor 47, a first gear 48, and a first toothed plate 49, and a second moving mechanism 6 consisting of a rotating seat 61, a rotating shaft 62, a second motor 63, a first bevel gear 64, a second bevel gear 65, a fixed strip 66, a second gear 67, and a second toothed plate 68, the connector 10 can move at any horizontal position. Simultaneously, in conjunction with a hydraulic cylinder 8, the connector 10 can move between the clean pipette tip box 13, the enzyme-labeled plate platform 15, and the waste pipette tip container 16. With the air pump 17, the pipette tip 5 can draw the washing solution through the connecting plate 9 and the connector 10. With the electromagnet 18 and the iron ring 19, the used pipette tip 5 can be quickly removed from the connector 10, thereby enabling the collection of waste pipette tips 5.
