Description

Technical Field

[0001] This utility model relates to sample preparation equipment, and more particularly to a fully automatic sample preparation device. Background Technology

[0002] In routine laboratory experiments, sample cutting or crushing is an indispensable step. Existing samples vary in size and shape, and the required level of processing differs, increasing the complexity of processing equipment. After processing, the cleaning process for existing sample processing equipment still relies on manual operation, requiring disassembly and separate handling. This increases operational complexity and the risk of contamination exposure, resulting in low efficiency, poor consistency, and a potential impact on the accuracy and purity of subsequent processing. These problems make sample processing and cleaning inconvenient and cumbersome, severely affecting work efficiency and the accuracy of experimental results. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a fully automatic sample preparation device that integrates sample preparation and cleaning and is easy to operate.

[0004] Technical solution: The fully automatic sample preparation device of this utility model includes a frame body, a sample preparation execution mechanism, a sample supply mechanism, and a control system. The sample preparation device also includes a cleaning mechanism, which adopts a dual-tank structure consisting of a separate cleaning tank and a drying tank. The control system is electrically connected to and controls the sample preparation execution mechanism, the sample supply mechanism, and the cleaning mechanism respectively.

[0005] Preferably, the cleaning tank is provided with a liquid inlet and a liquid outlet, and the drying tank is provided with an air inlet; the cleaning tank and the drying tank are independent and physically isolated cavity structures.

[0006] Preferably, the sample supply mechanism includes a sample preparation stage and an adjusting limiter. The adjusting limiter is used to limit the displacement of the disposable pad and fix the sample to be processed. The setting of the adjusting limiter enables the device to fix samples of different sizes and types, making it more adaptable.

[0007] Preferably, the adjusting limiting member includes a guide rod, a compression spring, a fixing member, and two or more movable blocks that are movably mounted on the guide rod.

[0008] Preferably, the sample preparation execution mechanism includes a fixed column, a horizontal moving module connected to the fixed column, a slide cylinder mounted on the horizontal moving module, and a processing module rotatably fixed on the slide cylinder. The processing module can quickly change to different types of processing tools according to the settings of the control system to adapt to the requirements of different samples, processing shapes, processing positions, and processing angles.

[0009] Preferably, the fixed column and the horizontal moving module are rigidly connected to ensure that there is no vibration or displacement during the sample preparation process.

[0010] Preferably, the control system includes a motion control module, a control screen, and switches. The control screen is used to input sample thickness, number of times, and position parameters to adapt to different experimental needs. The motion control module is connected to each actuator and controls the sample preparation actuator to perform movement or processing tasks, thereby achieving precise planning of the processing path and avoiding sample damage caused by repeated processing.

[0011] Beneficial Effects: Compared with the prior art, this utility model has the following advantages: This utility model achieves fully automated sample preparation for samples of different sizes and shapes by setting up a sample preparation execution mechanism, a sample supply mechanism, a cleaning mechanism, and a control system. The split-type cleaning mechanism, combined with the control system, controls the sample preparation execution mechanism to automatically transfer between the processing station, the cleaning tank, and the drying tank, realizing online cleaning and drying of the processing tools, reducing biosafety risks, and reducing manual operation steps; making the device feature integrated sample preparation and cleaning with simple operation.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-3As shown, this embodiment provides a fully automatic sample preparation device, including a frame body, a sample preparation execution mechanism 1, a sample supply mechanism 2, and a control system and a cleaning mechanism 3. The frame body serves as the mounting base for each functional mechanism, and the mechanisms are coordinated and controlled by the control system. The sample preparation execution mechanism 1 includes a fixed column 10 vertically fixed to the frame body, a horizontal moving module 8 rigidly connected to the fixed column 10, a slide cylinder 9 mounted on the horizontal moving module 8, and a processing module 11 connected to the end of the slide cylinder 9 via a rotation mechanism. The rigid connection structure between the horizontal moving module 8 and the fixed column 10 can eliminate vibration offset during the processing. The processing module 11 is driven by the slide cylinder 9 to achieve vertical processing action, and the processing angle is adjusted by the rotation mechanism. The processing tools of the processing module 11 can be replaced with different types of sample processing tools, such as hammers or knives, to meet diverse sample processing needs. The cleaning mechanism 3 consists of a physically isolated cleaning tank 4 and a drying tank 5. The cleaning tank 4 is provided with a liquid inlet and a liquid outlet, and the drying tank 5 is provided with an air inlet. After sample processing, the control system drives the processing module 11 to sequentially enter the cleaning tank 4 and the drying tank 5, completing a closed-loop cleaning process of detergent rinsing and clean gas drying, achieving zero contamination residue on the processing tools. The sample feeding mechanism 2 is equipped with an adjustable sample clamping assembly, including a sample preparation platform 7 and an adjusting limiter 6. The adjusting limiter 6 is used to limit the displacement of the disposable pad and fix the sample to be processed. The setting of the adjusting limiter 6 allows the device to fix samples of different sizes, types and shapes, making it more adaptable. The adjusting limiter 6 includes a guide rod, a compression spring, a fixing component, and two or more movable blocks that move through the guide rod, which can clamp the sample from all sides. The design of the adjusting limiter 6 can stably clamp samples of different sizes and shapes, ensuring processing position accuracy. The disposable pad can be replaced as needed, which also ensures the safety and hygiene of the processing process to a certain extent and avoids cross-contamination. The motion control module of the control system integrates motion control algorithms and is connected to the sample preparation actuator 1, sample supply mechanism 2, and cleaning mechanism 3 via signals. The control panel 12 has an input interface for processing angle, thickness, and number of times parameters, as well as a status display function. The switch 13 is used for device start-stop control. After the parameters are set through the control panel 12, the motion control module automatically generates the processing path and controls the coordinated operation of each actuator.

[0017] Specifically, the entire operation process of the device is as follows: the sample to be processed is placed in a disposable pad on the sample preparation stage 7 of the sample supply mechanism 2, and fixed by adjusting the limiting member 6; the switch 13 is turned on, and parameters such as processing thickness, number of times, and position are set through the control screen 12. The control system controls the horizontal moving module 8, the slide cylinder 9, and the processing module 11 of the sample preparation execution mechanism 1 to move according to the predetermined parameters. The horizontal moving module 8 drives the processing module 11 to the processing position, and the slide cylinder 9 presses down to drive the processing module 11 to complete the processing action. After processing, the processing module 11 enters the cleaning tank 4 for rinsing according to the preset program, and then is transferred to the drying tank 5 for drying.
