With continued reference to fig. 1 and 2, the following description will be made on the operation of the automatic liquid-separating and capping system for better understanding of the present invention.

The automatic liquid-separating and capping system is controlled and configured by the control unit, and the user transmits instructions through the operation screen 30. The specific process is as follows:

(1) after arranging the uncovered empty sample bottles 100 in the sample bottle array 3, the bottle caps 200 in the cap sorting mechanism 19, the reservoirs and the like, the system is initialized. The system initialization content includes sample array parameters, pneumatic parameters, speed parameters, etc. The system is started by setting parameters such as the amount of liquid to be injected, the position of the sample bottle 100 to be injected, and the like through the operation panel 30.

(2) The control unit controls the moving position of the liquid injection module 10 according to the coordinate position of the sample bottle 100, the liquid injection module 10 is moved to the upper part of the first sample bottle 100, and the liquid supply unit 7 inputs a predetermined amount of reagent liquid into the liquid injection module 10 to inject the reagent liquid into the sample bottle 100.

If the liquid is injected for the first time, the liquid injection pipeline and the liquid injection nozzle can be selected to be cleaned, the liquid injection nozzle is moved to the waste liquid pipe 29, and a certain amount of reagent liquid is supplied from the liquid supply unit 7 for flushing. If the supply of the reagent is switched by the solenoid valve 14 of the liquid supply unit 7, a flushing process is also performed.

When annotating liquid unit 5 and annotating liquid, will annotate liquid needle 11 and move to sample bottle 100 top, perhaps according to the kind of reagent, be fit for through annotating liquid needle elevating system 12, will annotate the liquid and stretch into sample bottle 100 and annotate the liquid, annotate the liquid and accomplish the back, will annotate liquid needle 11 and promote out sample bottle 100 again.

And injecting liquid into the plurality of sample bottles 100 in the sample bottle array 3 according to a preset sequence until all the sample bottles 100 with the set liquid injection are injected.

(3) After the liquid injection is finished, the control unit controls the cap screwing module 16 to suck the bottle caps 200 from the cap supply unit 8, controls the moving position of the cap screwing module 16 according to the coordinate position of the sample bottles 100, and sequentially screws the bottle caps 200 onto the sample bottles 100 through the rotation of the rotary suction head 17;

the cap arranging mechanism 19 of the cap supply unit 8 arranges the caps 200 into the inverted position and sends the caps to the cap sucking tool 21 through the cap output slot 20. The rotary suction head 17 of the screw-capping module 16 moves between the position of the suction-capping tool 21 and the sample bottle 100, sucks the bottle caps 200 on the suction-capping tool 21, and screws the bottle caps onto the sample bottle 100 in sequence. In order to ensure the effect of screwing the cap, a friction pad 28 is arranged below a bottle rack 27 of the sample bottle array 3, a rubber material can be selected, the bottom of a sample bottle 100 is contacted with the friction pad 28, a rotating suction head 17 presses a bottle cap 200 to rotate the sample bottle 100 from top to bottom, the rotation of the sample bottle 100 is limited by the friction force generated by the bottom of the sample bottle 100 and the friction pad 28, after the rotating suction head 17 rotates, the bottle cap 200 is screwed on the sample bottle 100, and the number of screwing turns is greater than that of threads of a mouth of the sample bottle 100. During screwing, the bottle cap 200 can be rotated in the reverse direction for half a circle or a circle at the bottle opening, and then the bottle cap is screwed in the forward direction, so that the bottle cap 200 is correctly matched with the threads of the bottle opening.

The cap arranging mechanism 19 can adopt bottle arranging machinery in the prior art, such as Chinese patent: a machine disclosed in 'a turnover-proof cap arranging machine with rake teeth' (application number: CN 201520746511.8). A vibratory mechanism 22 is positioned above vial cap output chute 20 and one or more sensors in the path of vial cap output chute 20 sense the condition of vial caps 200 within vial cap output chute 20 and, in the absence of a vial cap 200, cap collating mechanism 19 conveys a vial cap 200 onto vial cap output chute 20. The vibrating mechanism 22 vibrates the cap output chute 20 and sends the caps 200 to the cap suction tool 21. This process is continuous, and inverted caps 200 are sequentially arranged on the cap output chute 20 and the cap suction jig 21.

Since the caps 200 at the position of the cap suction tool 21 are closely arranged, cap suction failure may occur due to the influence of the caps 200 on the sides when the cap suction head 17 sucks the caps 200. In this case, the outermost cap 200 is lifted up from below by the lift pin 25 and the lift pin driving mechanism 26 below the cap support base 23, and the lifted cap 200 is sucked up by the rotary suction head 17 and then transferred to the sample bottle 100 to be screwed.

(4) After all the sample bottles 100 are completely screw-capped, the filling and screw-capping of a batch of sample bottles 100 is completed. The next batch of operations is performed after the new sample bottle 100 is replaced.

During liquid injection, the sample bottles close to the screw cap unit 6 can be started, after one or more rows of sample bottles are injected, the screw cap unit 6 can be simultaneously controlled to perform the screw cap operation on the sample bottles after the liquid injection is completed, and the operation time is saved by about three quarters.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
