The magnetic bead in cup 150 is answered to adsorb work, number consecutively is one to seven counterclockwise by this seven hole locations 113.Four imbibitions
Needle is located at two, four, six, seven, on four hole locations 113.Reaction cup disk 110 is according to cycle time T, in driving device 112
Under driving, a hole location 113 is rotated every time.In one to No. seven hole location 113 there are when reaction cup 150 to be cleaned, in each week
In time phase T, arc-shaped magnet moves forward, close to 150 outer wall of reaction cup under the driving of driving portion 131 along line slide rail.Reaction
Magnetic bead in cup 150 is attracted on 150 inner wall of reaction cup by magnetic fields.Cycle time T soon at the end of, arc
Magnet retracts initial position.
The process that the magnetic bead cleaning device 100 is cleaned is as follows:
Step1: reaction cup disk 110 is rotated by the period, and reaction cup 150 to be cleaned is first under the rotation of reaction cup disk 110
It is introduced into No.1 position.135 driven part 131 of magnetic receiver drives at this time, moves forward along line slide rail, keeps arc-shaped magnet close
Reaction cup 150.Magnetic bead in reaction cup 150 is adsorbed on 150 wall of reaction cup under the influence of magnetic field, after adsorbing a period of time, is driven
Dynamic portion 131 rotates backward, and so that arc-shaped magnet is left reaction cup 150, returns to original position.
Step2: reaction cup disk 110 is rotated by the period, and reaction cup 150 is sent to No. two positions.Driving portion 131 repeats step1
Middle movement, after reaction cup 150 stays for some time No. two positions, aspirating needle ontology 143 above No. two positions, in driving machine
It under structure 144 acts on, is dropped in reaction cup 150 along linear guide 145, siphons away liquid in reaction cup 150, and backed off after random reaction cup
150.During exiting reaction cup 150, aspirating needle ontology 143 can pass through the first purge block 1223, the first purge block 1223
On the second cleaning pipe 125, one is spat liquid, and an imbibition is clean by the remaining waste-liquid cleaning of 143 outer wall of aspirating needle ontology.It inhales
After liquid needle ontology 143 sets back, magnetic receiver 135 is under the effect of driving portion 131, along line slide rail far from reaction cup 150, reaction
Magnetic bead in cup 150 is no longer affected by magnetic fields.At this point, the first cleaning pipe 124 sprays cleaning solution on 150 side wall of reaction cup, beat
The magnetic bead being adsorbed on 150 wall of reaction cup is dissipated, is cleaned.
Step3: after cleaning, reaction cup disk 110 is rotated by the period, and reaction cup 150 is sent to third place, arc-shaped magnet
It repeats to act in step1
Step4: reaction cup disk 110 continues to rotate by the period, comes No. four positions.Each component actuation on No. four positions with
No. two position movements are identical in step2.
Step5: reaction cup disk 110 is rotated by the period, reaction cup 150 is sent to No. five positions, arc-shaped magnet repeats in step1
Movement.
Step6: reaction cup disk 110 is rotated by the period, and reaction cup 150 is sent to No. six position (second be arranged at No. six positions
It is not provided with the second cleaning pipe 125 in purge block 1224, therefore aspirating needle ontology 143 will not be cleaned).On No. six positions
Aspirating needle ontology 143 drops in reaction cup 150 along linear guide 145 under the effect of driving mechanism 144, siphons away reaction cup 150
Interior liquid, and backed off after random reaction cup 150.After aspirating needle ontology 143 sets back, magnetic receiver 135 driving portion 131 effect under,
Along line slide rail far from reaction cup 150, the magnetic bead in reaction cup 150 is no longer affected by magnetic fields.At this point, the first cleaning pipe 124 to
Cleaning solution is sprayed on 150 side wall of reaction cup, the magnetic bead being adsorbed on 150 wall of reaction cup is broken up, is cleaned.
Step7: reaction cup disk 110 is rotated by the period, and reaction cup 150 is sent to No. seven positions.Arc-shaped magnet is in driving portion 131
Under effect, and close to 150 wall of reaction cup, reaction is gathered by the magnetic bead that the first cleaning pipe 124 is sent forth again under magnetic fields
On 150 walls of cup.After reaction cup 150 stays for some time No. seven positions, aspirating needle ontology 143 above No. seven positions is being driven
Under motivation structure 144 acts on, is dropped in reaction cup 150 along linear guide 145, siphon away liquid in reaction cup 150, and backed off after random is anti-
Cup 150 is answered, the cleaning of magnetic bead is completed.
Second embodiment
