Description

Technical Field

[0001] The utility model relates to the technical field of sample pre-processing in food safety testing laboratories, in particular to a liquid sample oscillation processing functional island. Background Art

[0002] In the sample pre-treatment system of the food safety testing laboratory, it is necessary to mix the sample and the reagent. When encountering samples with high viscosity and easy to clump, general operations such as vortexing and ultrasound cannot break up such sample clumps or sample blocks, making it impossible to fully mix the sample and reagent. This operation is usually completed manually, by a mixer or an oscillator. In the prior art, manual oscillation is time-consuming and labor-intensive, the force of the mixer or oscillator on the sample is limited, and the test tube containing the sample is randomly swung. The start and stop positions of the oscillation of the test tube are random, and manual identification is required before manual picking, which is very inconvenient and inefficient. In addition, the timeliness and accuracy of the process feedback are low, which is not conducive to the cooperation with the robot system to achieve intelligent grasping. The existing functional island is not intelligently controlled, and the entire experimental process has poor accuracy and low efficiency. Therefore, the automatic and intelligent oscillation processing of the sample is of great significance for the sample pre-treatment of the food safety testing laboratory.

[0003] Therefore, the inventors, relying on their many years of experience and practice in related industries, have proposed a liquid sample oscillation processing functional island to overcome the defects of the prior art. Utility Model Content

[0037] like Figures 1 to 4 As shown, the utility model provides a liquid sample oscillation processing functional island, comprising:

[0038] A shaker 1 is provided with a roller for rocking and oscillating the sample tube. A servo power system is connected to the shaker 1 to drive the roller to rock and stop the rocking of the sample tube 2 at a set position. The servo power system precisely controls the start and stop positions of the roller, and the test tube is placed at a fixed angle each time. The robot system can accurately place or remove the test tube.

[0039] A manipulator system 3 for grabbing and transporting sample tubes 2; the manipulator system 3 is stable and accurately places the sample tubes, and its working trajectory can achieve high precision, making it a high-precision manipulator;

[0040] A test tube turning seat 4 for turning over the sample test tube 2;

[0041] The control unit, servo power system, and manipulator system 3 are all electrically connected to the control unit. The control unit can be set up in the overall control system of the entire food safety testing laboratory sample pretreatment system, supporting equipment terminal control and system remote control. It also has a user-friendly human-computer interaction interface, can operate the functional island equipment, display the functional island equipment status, and provide operation information and operation prompts.

[0042] In the liquid sample oscillation processing functional island of the present invention, the servo power system controls the position of the sample tube's oscillation in the shaker, which can stop the sample tube from oscillating at the set position, making it easier for the robot system to accurately grab the sample tube from the shaker; the robot system realizes the transportation of the sample tube within the functional island and to the main transmission line, and the grabbing is stable and the placement is accurate, which is convenient for automated control; the tube flipping seat overcomes the problem that the robot cannot accurately adjust the placement angle of the sample tube due to limited space, and assists the robot system to complete the flipping and positioning of the sample tube before the shaker; the control unit controls the actions of various functional components in the liquid sample oscillation processing functional island, thereby realizing fully automatic oscillation and mixing of the liquid sample in the experiment, thereby improving the full automation and intelligence of the overall sample pre-treatment system.

[0043] Further, if Figure 1 、 Figure 2 As shown, the liquid sample oscillation processing functional island of the present invention also includes a barcode scanner 5 for scanning and verifying the sample tube 2. Barcode scanner 5 is electrically connected to the control unit. Labels are attached to the sample tubes 2. Barcode scanner 5 scans and accurately records the sample tubes 2. The scanned information is transmitted to the control unit, which verifies whether the scanned object is the work object, ensuring the accuracy of the automated operation.

[0044] Further, if Figure 1 、 Figure 4 As shown, the test tube turning stand 4 includes a base 41 on which a test tube support body for horizontally supporting the sample test tube 2 is provided. A shift stop plate 42 is provided on one side of the test tube support body for stopping the bottom end of the sample test tube 2 when it is turned to the horizontal position.

[0045] Further, if Figure 4 As shown, the test tube support body includes a support bottom plate 43 and at least two support vertical plates 44 arranged at intervals, and a V-shaped groove is provided on the support vertical plates from the top downward.

[0046] Further, if Figure 4 As shown, the base 41 is configured as an L-shaped folded plate, and a reinforcing rib plate 45 is connected to the L-shaped folded plate.

[0047] Due to the compact layout requirements of the sample pre-processing system of the entire food safety testing laboratory, the space of each functional island is limited, so the movement trajectory and action space of the manipulator system 3 are limited. When the sample tube 2 is transported from the system transportation line, it is in a vertical state, while the sample tube 2 needs to be in a horizontal state to oscillate in the shaking table 1. Therefore, the sample tube 2 needs to be flipped from the vertical state to the horizontal state. The manipulator system 3 can first transport the sample tube 2 to the tube flip seat 4. After the bottom end of the tube flip seat 4 abuts against the repositioning stop plate 42, the manipulator system 3 releases the sample tube 2, and the sample tube 2 is flipped and placed flat on the tube support body, completing the flip of the sample tube 2 to the horizontal position. The horizontal sample tube 2 is then transported to the shaking table 1 by the manipulator system 3.

[0048] Further, if Figure 1 、 Figure 2 As shown, the liquid sample oscillation processing functional island of the present invention further includes a test tube temporary storage rack 6 for caching sample test tubes 2 , and a barcode scanner 5 is disposed between the test tube temporary storage rack 6 and the shaking table 1 .

[0049] Furthermore, the test tube temporary storage rack 6 is provided with slots for vertically storing sample test tubes.

[0050] The sample tubes 2 are used to temporarily store the sample tubes 2 to be processed from the system transport line, or the sample tubes 2 after being shaken by the shaker 1 .

[0051] Further, if Figure 1 、 Figure 2 、 Figure 3 As shown, the liquid sample oscillation processing functional island of the present invention also includes a functional island workbench 7 for supporting a fixed shaking table 1, a manipulator system 3, a test tube turning seat 4, a barcode scanner 5, and a test tube temporary storage rack 6.

[0052] Further, if Figure 1 、 Figure 2 、 Figure 3 As shown, the manipulator system 3 includes a manipulator main shaft 31 that is vertically arranged and can rotate horizontally, and a horizontal folding arm 32 that can be raised and lowered is rotatably connected to the manipulator main shaft 31. The free end of the horizontal folding arm 32 is provided with a clamping claw 33 for grabbing the sample tube.

[0053] Furthermore, the servo power system includes a servo motor that drives each sample tube 2 to controllably rotate between start and stop positions (start position and stop position). The controllable start and stop positions ensure that when the sample tube 2 is in the stop position, the visual element (label, etc.) on the bottle body is visible, facilitating identification.

[0054] As described above, the liquid sample oscillation processing functional island of the present invention has the following beneficial effects:

[0055] In the present invention, the servo power system controls the position of the swinging oscillation of the sample tube in the shaker, which can stop the sample tube from swinging at the set position, making it easier for the robot system to grab the sample tube from the shaker; the robot system realizes the transportation of the sample tube in the functional island and to the main transmission line, and the grabbing is stable and the placement is precise, which is convenient for automated control; the tube flipping seat overcomes the problem that the robot cannot accurately adjust the placement angle of the sample tube due to limited space, and assists the robot system to complete the flipping and positioning of the sample tube before the shaker; the control unit controls the actions of various functional components in the liquid sample oscillation processing functional island, thereby realizing fully automatic oscillation and mixing of the liquid sample in the experiment, thereby improving the full automation and intelligence of the overall sample pre-treatment system.
