Description

Technical Field

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

[0002] In the sample pre-treatment system of the food safety testing laboratory, the sample needs to be centrifuged (solid-liquid separation), which is usually completed by a centrifuge.

[0003] Existing centrifuge equipment primarily relies on manual placement of sample tubes, instrument settings, and startup to complete the centrifugation process. Furthermore, before the tubes are placed into the centrifuge, they must be manually weighted to ensure separation, minimize equipment wear, and prevent safety incidents. Beyond the centrifugation process, all other steps—weighting, tube placement, equipment startup, and tube removal after centrifugation—require manual labor.

[0004] At the same time, the centrifugal rotating bracket in existing centrifuges has a random start and stop position, which is not conducive to cooperating with the robot system to achieve intelligent grasping. The default tilted tube placement and top cover opening of the centrifuge rotor are not suitable for robot feeding. Moreover, the current manual balancing operation method cannot cooperate with the robot system to achieve intelligent picking and placing. The entire centrifugation process has a low degree of automation and is labor-intensive. Therefore, there is an urgent need for a device that can achieve fully automated centrifugal processing.

[0005] Therefore, the inventors, relying on their many years of experience and practice in related industries, have proposed an intelligent centrifugal processing functional island to overcome the defects of the prior art. Utility Model Content

[0049] like Figures 1 to 4 As shown, the utility model provides an intelligent centrifugal processing functional island, comprising:

[0050] A centrifuge 1 for centrifugally rotating a separation medium has an openable and closable feed port 11 at the top of the centrifuge 1. A centrifugal rotating support 12 for supporting a sample test tube 8 is provided below the feed port 11 within the centrifuge 1. The centrifugal rotating support 12 is connected to a servo power system that controls the start and stop positions of its rotation. The servo power system precisely controls the start and stop positions of the centrifugal rotating support 12, ensuring that the test tube is placed at a fixed angle each time, allowing a robotic arm system to accurately place or remove the test tube.

[0052] The test tube transfer structure 3 is used to place the sample test tubes transported by the manipulator system 2 onto the centrifugal rotating rack 12. The test tube transfer structure 3 is connected to a transfer power motor. To ensure the sealing of the centrifuge, the opening of the feed port 11 is generally small. Due to the angle and space limitations of the manipulator system 2, it is unable to accurately place the sample test tubes. A special test tube transfer structure 3 is required to cooperate with the manipulator system 2 to complete the placement of the sample test tubes in the centrifugal rotating rack 12.

[0053] A counterweight structure for balancing the weight of the sample tube on the centrifugal rotating support 12;

[0054] The control unit, servo power system, manipulator system 2, and power transmission motor 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. It supports terminal control of equipment and remote control of the system. It has a friendly human-computer interaction interface, can operate functional island equipment, display functional island equipment status, and provide operation information and operation prompts.

[0055] In the intelligent centrifugal processing functional island of the present invention, the servo power system controls the position of the centrifugal rotation of the sample test tube in the centrifugal rotating bracket, which is controllable and can stop the sample test tube from rotating at the set position, so that the manipulator system can accurately grab the sample test tube from the centrifuge; the manipulator system realizes the transportation of the sample test tube in 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 test tube transfer structure overcomes the problem that the manipulator cannot accurately place the sample test tube on the centrifugal rotating bracket due to angle and space limitations, and assists the manipulator system to complete the transfer and placement of the sample test tube before entering the centrifuge; the control unit controls the actions of various functional components in the intelligent centrifugal processing functional island, so as to realize fully automatic centrifugal separation of liquid samples in the experiment, thereby improving the full automation and intelligence of the overall sample pre-treatment system.

[0056] Further, if Figure 1 、 Figure 3 As shown, the intelligent centrifugal processing functional island of the present application further includes a barcode scanner 5 for scanning and checking the sample tubes, and the barcode scanner 5 is electrically connected to the control unit.

[0057] A label is attached to the sample tube, and the barcode scanner 5 scans the sample tube and records it accurately. The scanning information is transmitted to the control unit, which checks whether the scanned object is the operation object to ensure the accuracy of the automated operation.

[0058] Further, if Figure 1 、 Figure 2 、 Figure 3 As shown, the test tube transfer structure 3 includes a lateral transfer portion 31 and a test tube delivery portion 32;

[0059] The transverse transfer unit 31 includes a transverse guide rail, a transverse block is movably provided on the transverse guide rail, and an openable and closable transverse clamp is provided on the transverse block.

[0060] The test tube delivery part 32 includes an oblique guide rail, which is supported on an oblique support and inclined at a set angle to the vertical direction, and the angle can be adjusted according to actual needs; an oblique block is movably provided on the oblique guide rail, and an openable and closable oblique clamp is provided on the oblique block; the transverse clamp is inclined at a certain angle so that the sample test tube it clamps is inclined and has the same inclination angle as the oblique guide rail; the oblique clamp is used to receive and clamp the sample test tube from the transverse transfer part 31, and is driven by the oblique block to move obliquely to transfer the sample test tube to the centrifugal rotating bracket 12.

[0061] Furthermore, the power transmission motor includes a traverse motor and a tilt motor; the traverse motor and the tilt motor are electrically connected to the control unit;

[0062] The traverse motor is connected to the traverse guide rail; the traverse guide rail is a first screw, and a first nut is provided on the traverse block. The traverse motor drives the traverse guide rail to rotate so that the first nut moves along the first screw;

[0064] Furthermore, the transverse moving clamp and the oblique moving clamp are provided with opening and closing sensors, and the opening and closing sensors are electrically connected to the control unit.

[0065] Due to the compact layout requirement of the sample pretreatment system of the entire food safety testing laboratory and the limited space of each functional island, the movement trajectory and action space of the manipulator system 2 are limited. When the sample tubes are transported from the system transportation line, they are in a vertical state, and the slots for placing the sample tubes on the centrifugal rotating bracket 12 in the centrifuge 1 are tilted. Therefore, the sample tubes need to be inserted into the centrifugal rotating bracket 12 from the tilted state.

[0066] The manipulator system 2 can first transport the sample test tube to the transverse transfer part 31, and the transverse clamp clamps (completes the action under the drive of its opening and closing sensor) the sample test tube.

[0068] The counterweight unit 42 adopts a standard block structure, which is convenient for the manipulator system 2 to grasp.

[0069] Further, if Figure 1 、 Figure 2 、 Figure 3 As shown, the intelligent centrifugal processing functional island of the present invention further includes a test tube temporary storage rack 6 for caching sample test tubes 8.

The manipulator main shaft 21 is rotatably connected to a horizontal folding arm 22. The free end of the horizontal folding arm 22 is provided with a clamping claw 23 for grabbing the sample tube.

[0072] Furthermore, the servo power system includes a servo motor, which drives the centrifugal rotating bracket to controllably rotate between start and stop positions (start position and stop position).

[0073] In a specific embodiment of the present invention, Figure 4 As shown, the centrifugal rotating support 12 can support and place three large-diameter test tubes and three small-diameter test tubes, and the large-diameter test tubes and the small-diameter test tubes are arranged alternately.
