Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, for a kind of cell-stain apparatus photoelectric detection mechanism of the present utility model, it comprises fixed mount 10, tressel 20, a plurality of transfer pipet 30, the driving mechanism for driving tressel 20 to move up and down with respect to fixed mount 10 along short transverse, controller and photoelectric detector.
Wherein, fixed mount 10 is as the installation basis of whole device, it can be the frame of cell-stain apparatus, the both sides of fixed mount 10 are respectively arranged with a guide pole 11 extending along short transverse, what slided respectively in the both sides of tressel 20 is socketed on two guide poles 11, driving mechanism comprises the motor 51 of body partial fixing on fixed mount 10, synchronously be connected in the rotating shaft of motor 51 and the drive lead screw 52 extending along short transverse, what mate is socketed on drive lead screw 52 and the feed screw nut 53 who is fixedly connected with tressel 20, the control end of motor 51 is connected with controller, that is to say, controller can be controlled this motor 51 and quit work.
Photoelectric detector comprises transmitting terminal 41 and receiving end 42, transmitting terminal 41 and receiving end 42 are fixedly mounted on respectively the inside sidewalls of fixed mount 10 Width both sides, above-mentioned a plurality of transfer pipets 30 are all fixedly connected on the bottom of tressel 20 and are arranged in row along the Width (being the Width of fixed mount 10) of tressel 20, and between transmitting terminal 41 and receiving end 42, transmitting terminal 41, a plurality of transfer pipets 30 and receiving end 42 are arranged in row on the Width of fixed mount 10, the light ejaculation direction that is transmitting terminal 41 overlaps with the orientation of a plurality of transfer pipets 30.Photoelectric detector for taking arms 60, when moving back rifle head 60 and getting liquid respectively to controller transmitted signal, whether the signal control motor 51 that controller sends according to photoelectric detector quits work.
Referring to Fig. 1, during use, driving mechanism drives a plurality of transfer pipets 30 to move down and extracts a plurality of rifle heads 60 placed side by side in reagent rack simultaneously, after extracting rifle head 60, driving mechanism drives on transfer pipet 30 and moves between the transmitting terminal 41 and receiving end 42 of photoelectric detector, now, transmitting terminal 41 penetrates light, receiving end 42 receives the light signal that transmitting terminal 41 penetrates, because rifle head 60 is that transparent plastic is made, the light that transmitting terminal 41 penetrates can receive through a plurality of rifle heads 60 receiving ends 42 side by side, because light has certain loss when through rifle head 60, therefore after passing the rifle head 60 of varying number, the intensity of the light signal that receiving end 42 receives is different, therefore, while there is no rifle head 60 on having more than one transfer pipet 30, the light signal that receiving end 42 receives will inevitably be than all having the light signal of rifle head 60 strong on whole transfer pipets 30, so, while there is no rifle head 60 on having more than one transfer pipet 30, photoelectric detector sends to controller by detection signal, controller is according to the signal detecting, light signal strength and setting value that receiving end 42 is received compare, when the actual light signal strength receiving of receiving end 42 is greater than setting value, explanation has at least a transfer pipet 30 there is no rifle head 60, now, controller is controlled motor 51 and is quit work, motor 51 can not drive transfer pipet 30 to get liquid, certainly, an alarm also can be set, when there is above-mentioned situation, controller is controlled alarm equipment alarm.Referring to Fig. 2, moving back after rifle head 60 completes, driving mechanism drives transfer pipet 30 to move to top a little position between the transmitting terminal 41 of photoelectric detector and receiving end 42, now, when the rifle head 60 on having more than one transfer pipet 30 is not returned, because can making the light of transmitting terminal 41, rifle head 60 has part loss, therefore, the light signal strength that receiving end 42 receives is different from the light signal strength of controller internal preset, and this Time Controller is controlled motor 51 and quit work and/or alarm equipment alarm.For another example Fig. 1, after transfer pipet 30 imbititions with rifle head 60, driving mechanism drives rifle head 60 to move between transmitting terminal 41 and receiving end 42, when the liquid level in a plurality of rifle heads 60 there are differences, explanation, have at least a liquid dosages in rifle head 60 could not reach the dosage of needs or surpass the dosage needing, photoelectric detector sends a signal to controller, and controller quits work and/or alarm equipment alarm according to this signal control motor 51.
In the utility model, be respectively arranged with a fixed beam 12, two fixed beams 12 and the settings side by side of a plurality of transfer pipets 30 on the side plate inwall of the both sides of fixed mount 10, the transmitting terminal 41 of photoelectric detector and receiving end 42 are arranged on respectively on two fixed beams 12.In order to be applicable to different rifle heads 60, a plurality of connecting portions of equidistantly arranging along short transverse can be set on fixed beam 12, the transmitting terminal 41 of photoelectric detector and receiving end 42 are dismountable to be connected on connecting portion, can be according to the length of rifle head 60, adjust the height and position of transmitting terminal 41 and receiving end 42, if guarantee its two in the same horizontal line.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
