In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention.
Embodiment
The present embodiment provides a kind of sample conveying device, including：
Conveying mechanism 100, as shown in Figure 1, including bottom plate (being divided into upper plate and lower plate), two on upper plate
Bar parallel loading guide 101 and blanking guide rail 102, are exposed to two parallel feeding conveyors 103 and the blanking of upper plate
Conveyor 104, is provided with driving wheel between upper plate and lower plate, feeding conveyor 103 and blanking conveyor 104 are respectively arranged on one
To on driving wheel, feeding conveyor 103 and blanking conveyor 104 are driven by power set and drive sample rack 900 respectively along upper
Material guide rail 101 and blanking guide rail 102 move；
Blocking mechanism 200, as shown in figure 3,101 end of loading guide is arranged on, including baffle 300 and stop driving part
201,
Baffle 300, as shown in Fig. 2, positioned at bottom plate one end of conveying mechanism 100, have recessing groove 301, barcode scanning groove 302,
The function of relief hole 303, recessing groove 301 and relief hole 303 hereinafter has narration, and barcode scanning groove 302 is to allow barcode scanning light to wear
Cross；
Stop driving part 201 is arranged on upper plate, and (upper plate is usually by being provided with baffle 300 and being provided with guide rail 101
Two parts composition) bottom stop guide rail 203, be arranged on guide rail 203 be blocked driving part 201 drive and along stop
Guide rail 203 moves and stop sliding block 202 close or away from baffle 300, and positive stop is provided with the stop sliding block 202
211 and backstop 212, a sample rack 900, positive stop 211 and backstop can be accommodated between positive stop 211 and backstop 212
212 are respectively provided with the raised position for protruding from upper plate and the non-bulging decline state in upper plate, as a kind of concrete implementation
Mode positive stop 211 and backstop 212 are arranged on elastic component (to be set in the rotation axis of positive stop 211 and backstop 212
Torsional spring), elastic component provides elastic force for positive stop 211 and backstop 212 so that positive stop 211 and backstop 212 are without other outer
Raised position is returned under power effect, one side of the positive stop 211 away from baffle 300 is inclined-plane, and backstop 212 is close to baffle 300
Be simultaneously inclined-plane so that sample rack 900 by positive stop 211 when, positive stop 211 can be depressed (make positive stop 211 from
Raised position is changed into decline state, and to prevent positive stop 211 from stopping, sample rack 900 recovers raised by rear positive stop 211 immediately
State), when positive stop 211 and backstop 212 are with stopping that sliding block 202 together moves, backstop 212 is depressed (after making by lower plate
Block 212 is changed into decline state from raised position), positive stop 211 pushes sample rack 900 against firmly baffle 300；
Pushing mechanism 400, for promoting sample rack 900, makes sample rack 900 be moved along baffle 300, in the process,
Barcode scanning, sampling are carried out to each sample tube on sample rack 900 one by one, including：Pushing motor 402, pushing motor 402 drive
Pushing plate 401 moves (baffle 300 is moved along recessing groove 301) along baffle 300, so as to promote sample rack 900；
Cutting agency 500, as shown in figure 4, for blanking guide rail 102 will to be shifted onto positioned at the sample rack 900 of 300 end of baffle
On, so that sample rack 900 can be driven by blanking conveyor 104, and pushing motor 501, push rail 503, pushing motor 501
So that push plate 502 moves reciprocatingly along push rail 503, push plate 502 can pass through relief hole 303 for drive rocker mechanism 504
So as to promote the sample rack 900 positioned at 300 side of baffle.
The transportational process of the present embodiment conveying device is as follows：Sample rack 900 is placed on to the feed entrance point of loading guide 101
Locate (lower right side in figure), drive sample rack 900 to reach (blocking mechanism 200 at blocking mechanism 200 when feeding conveyor 103 is moved
Positioned at apart from the position of 300 distalmost end of baffle), first, sample rack 900 can pass through and depress positive stop 211, once sample rack
900 cross positive stop 211, and positive stop 211 is raised, and sample rack 900 is fixed between positive stop 211 and backstop 212.So
Afterwards, the sample rack 900 at blocking mechanism 200 will wait previous sample rack 900 i.e. at the sample rack 900 at baffle 300
Whether reason finishes, (be disposed by sensor to monitor, when sensor sensing arrives once previous sample rack 900 is disposed
At baffle 300 during no specimen frame 900, will start and stop driving part 201), stop that driving part 201 will be run so that will
Stop that sliding block 202 connects sample rack 900 and drives close baffle 300 together, positive stop 211 is depressed in the process, positive stop
211 push sample rack 900 against baffle 300 is lived, and afterwards, stop 202 return-to-home position of sliding block.Sample rack 900 is against firmly baffle
300, the pushing motor 402 of pushing mechanism 400 starts, and promotes sample rack 900 to be moved one by one to sample rack 900 along baffle 300
Upper each sample tube carries out barcode scanning, sampling, after the completion of sample rack 900 be pushed at 500 position of cutting agency (also position at the same time
In 300 end of baffle).Finally, the pushing motor 501 of cutting agency 500 starts, and shifts sample rack 900 onto blanking guide rail 102
On, blanking conveyor 104 drives sample rack 900 to reach lower discharge position (upper right side in figure).Stop and whether there is sample at driving part 201
This 900 is also to be monitored by inductor, if stopping no specimen frame 900 at driving part 201, can control feeding conveyor
103 come a sample rack 900 from the transport of upper material position.
The sample conveying device of the present embodiment, sample rack 900 is finally by blocking mechanism 200, particularly by 211 He of positive stop
Backstop 212 is fixed to transport baffle 300 (namely sample position) place, is made by baffle 300 and the fixed of backstop 212
With, can make sample rack 900 keep fixed pose.In the presence of having sample rack 900 at baffle 300 at the same time, backstop
212 can prevent next sample rack 900 from entering at baffle 300, ensure that sampling is sequentially accurate and carry out.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
