It is careful, syringe needle slight inclination lead to error.
Further, the length at imbibition end is less than the length of Z axis screw 210c, and the imbibition end is moved downward to imbibition end
Collect invisible spectro sample.So the Z axis screw 210c of Z axis driving mechanism 210 limits the length at imbibition end, but inhale
The width at liquid end not in the range of limitation, amount that imbibition end is drawn to a certain extent for be interior conditional.
Still further, the imbibition end is moved downwardly toward testing liquid in this test tube, until imbibition end collects test tube
Interior sample.This process could be provided as being automatically performed, and may be set to be and manually completes, depending on actual conditions.
The cleaning structure 400 is placed on the workbench 140 of 210 lower section of Z axis driving mechanism, and the workbench 140 is in institute
It states and clean frame 410 and rack for test tube is respectively equipped in the moving area at the imbibition end of imbibition head assembly 300, in the clean frame 410
Several clean tanks are provided with, are contained with to carry out clean cleaning to the imbibition end of imbibition head assembly 300 in the clean tank
Liquid is provided in the rack for test tube several for holding the test tubes of sample.
Further, the workbench 140 is additionally provided in the moving area at the imbibition end of the imbibition head assembly 300
Monitor station, the monitor station are equipped with injection port.
Further, at least one injection port 111 is provided on monitor station 110.Further, wiper mechanism is set to
In rack 100, the wiper mechanism includes clean frame 410 and the multiple clean tanks 411 being set on clean frame 410, imbibition end
Syringe needle is driven to stretch into clearly under the effect of being linked of Z axis driving structure 210, Y-axis driving structure 220 and X-axis driving structure 230
Clean frame 410.
The height of clean frame 410 is set below 210 bottom end of Z axis driving mechanism, and multiple Shengs are opened up on clean frame 410
The clean tank 411 of cleaning solution is put, the imbibition head assembly 300 drives in X-axis driving mechanism 230, Y-axis driving mechanism 220 and Z axis
It is moved under the driving of mechanism 210 to clean tank 411.
Preferably, monitor station 110 is set to 410 one end of clean frame.In this way, when being sampled next time, Ke Yizhi
It connects and cleans syringe needle nearby, reduce three axis shift motions, simple in structure, reasonable design.
Further, the setting of the monitor station 110 is not higher than Y-axis driving structure 220, can not be moved to avoid syringe needle
On monitor station 110, sample to be tested cannot be contacted with injection port 111.
After syringe needle acquires sample, acted on by Y-axis driving structure 220 or 230 ground of X-axis driving structure, by imbibition
End is moved to 110 top of monitor station, and syringe needle is corresponding with injection port 111.Detected sample is contacted with injection port 111, injection port 111
Sample data is conveyed away after receiving data.
Still further, the embedded groove 141 being adapted with 120 bottom end of rack for test tube, the test tube are set on workbench 140
Frame 120 is set as at least one set of.
Wherein, multigroup rack for test tube 120 is equipped with below imbibition head assembly 300, is provided on the rack for test tube 120 equidistant
Test tube placing groove 121, the rack for test tube 120 are embedded in rack 100.
Further, the setting of multiple clean tanks 411 is the sample in order to when imbibition head assembly 300 detects different samples
Traits change between product is excessive, and a clean tank 411 is easily contaminated and does not have cleaning effect.So the rack for test tube 120 is set
Be set to it is at least one, in institute's sample during character approximation.
Wherein, the clean frame 410 is arranged in parallel with X-axis driving structure 230.
Further, clean frame 410 is placed between X-axis driving structure 230 and rack for test tube 120.
At this point, after syringe needle acquisition sample, the linkage of Z axis driving structure 210 and Y-axis driving structure 220 is only needed to match
It closes, with regard to cleaning can be carried out.X-axis driving structure 230 does not need to adjust, and makes operation more convenient.
Likewise, clean frame 410 and X-axis driving mechanism 230 are vertical setting.
At this point, after imbibition head assembly 300 acquires sample, Z axis driving structure 210 and X-axis driving structure 230 are only needed
Be linked, with regard to cleaning can be carried out.Y-axis driving structure 220 does not need to adjust, and makes operation more convenient.
This fluid sample sampler, the imbibition head assembly 300 is in Z axis driving structure 210, Y-axis under motor effect
Driving structure 220 and being linked for X-axis driving structure 230 are moved to 120 top of rack for test tube, the imbibition head assembly 300
On imbibition end syringe needle is driven to move closer to liquid to be detected sample along Z-direction guide rail 210b, fluid suction head is passed through on guide pad 320
Avoid holes 231d acquire invisible spectro fluid sample after, then pass through Z axis driving structure 210, Y-axis driving structure 220 and X-axis and drive
Dynamic being linked for structure 230 is moved on the injection port 111 of monitor station 110, and then injection port 111 transmits data.Finally will
Imbibition end, which is stretched into, carries out easy clean in the clean tank 411 of cleaning structure nearby, repeat new liquid sample collecting process.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Described specific embodiment can be done various modifications or additions or using similar by belonging to those skilled in the art
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
