Technical Field

[0001] This utility model relates to the field of pipetting devices, and in particular to an electric pipetting device for the detection of traditional Chinese medicine. Background Technology

[0002] An electric pipette is an automated device used for liquid transfer in laboratories. It typically consists of an electric drive system, a pipette, and a control panel. It accurately aspirates and releases liquids electrically, replacing traditional manual pipetting operations and greatly improving the efficiency and accuracy of experiments. Electric pipettes usually have functions such as adjusting the aspiration volume, controlling the aspiration speed, and avoiding cross-contamination. They are widely used in laboratories in fields such as biology, chemistry, medicine, and pharmaceuticals, and are particularly suitable for liquid transfer tasks that require high precision and high repeatability.

Detailed Implementation

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an electric pipetting device for detecting traditional Chinese medicine, comprising a worktable 1, a support plate 3 fixedly connected to the upper surface of the worktable 1, a second motor 301 fixedly connected to the outer wall of the support plate 3, a rotating plate 302 fixedly mounted at the output end of the second motor 301, a sliding column 303 fixedly connected to the outer wall of the rotating plate 302, a first rotating rod 304 slidably connected to the inner wall of the rotating plate 302, a fixing plate 305 rotatably connected to the outer wall of the first rotating rod 304, and the lower surface of the fixing plate 305 fixedly connected to the upper surface of the worktable 1. On the surface, a second rotating rod 306 is fixedly connected to the outer wall of the fixed plate 305, a slider 307 is slidably connected to the outer wall of the second rotating rod 306, a rotating column 308 is fixedly connected to the inner wall of the slider 307, the outer wall of the rotating column 308 is slidably connected to the inner wall of the fixed plate 305, a rotating rod 309 is fixedly connected to the lower surface of the rotating column 308, a liquid-taking head 310 is fixedly connected to the inner wall of the rotating rod 309, an infusion head 311 is fixedly connected to the inner wall of the rotating rod 309, and a moving component is provided on the upper surface of the workbench 1 for moving the test tube;

[0026] Specifically, the second motor 301, supported by the support plate 3, is activated. The second motor 301 drives the rotating plate 302 and the sliding column 303 to rotate. During the rotation of the rotating plate 302, the first rotating rod 304 is pushed to rotate within the fixed plate 305. In use, this restricts the movement trajectory of the first rotating rod 304 to prevent deviation. As the first rotating rod 304 moves, it pushes the second rotating rod 306 to make the slider 307 slide. In use, this restricts the movement trajectory of the slider 307 to prevent deviation. The sliding of the slider 307 drives the rotating column 303 to rotate. The 08 movement of the rotating column 308 pushes the rotating rod 309 to slide. While the rotating rod 309 slides, it drives the liquid collection head 310 and the infusion head 311 to move. In use, it can drive the rotating rod 309 to make vertical movements. While the rotating plate 302 rotates, the sliding column 303 pushes the rotating column 308 to rotate. The rotation of the rotating column 308 drives the liquid collection head 310 and the infusion head 311 to rotate. In use, it can enable the pipetting assembly to rotate during the lifting and lowering process so that the test tube does not touch the inner wall of the container and can automatically inject.

[0027] Reference Figure 3The moving component includes a support plate 3, the lower surface of which is fixedly connected to the upper surface of the workbench 1. A third motor 4 is fixedly connected to the outer wall of the support plate 3. A sector tooth 5 is fixedly provided at the output end of the third motor 4. A first rack 6 is meshed with the tooth ends of the sector tooth 5. A connecting column 7 is provided on the inner wall of the first rack 6. A second rack 8 is provided on the outer wall of the connecting column 7. A slide table 9 is slidably connected to the lower surface of the second rack 8. The outer wall of the slide table 9 is fixedly connected to the upper surface of the workbench 1. A placement platform 10 is fixedly connected to the outer wall of the first rack 6. A stirring component is fixedly connected to the upper surface of the workbench 1.

[0028] Specifically, the third motor 4, protected by the support plate 3, is activated. The third motor 4 drives the sector tooth 5 to push the first rack 6 to slide. The first rack 6 slides on the slide table 9 supported by the worktable 1. During use, it has the effect of limiting the movement trajectory of the first rack 6 to prevent deviation. The movement of the first rack 6 drives the platform 10 to move. When the first rack 6 moves to the end, the sector tooth 5 will push the second rack 8 set on the connecting column 7, which can make the second rack 8 quickly reset and facilitate multiple uses.

[0029] Reference Figure 4 The stirring assembly includes a housing 2. The lower surface of the housing 2 is fixedly connected to the upper surface of the workbench 1. A first motor 201 is fixedly connected to the upper surface of the housing 2. A triangular rod 202 is fixedly installed at the output end of the first motor 201. A toothed ring 203 is rotatably connected to the outer wall of the triangular rod 202. The toothed ring 203 is triangular in shape. A first gear 204 is meshed with the tooth end of the toothed ring 203. The outer wall of the first gear 204 is rotatably connected to the inner wall of the triangular rod 202. A second gear 205 is fixedly connected to the outer wall of the first gear 204. A third gear 206 is meshed with the tooth end of the second gear 205. The inner wall of the third gear 206 is rotatably connected to the outer wall of the triangular rod 202. A support plate 207 is fixedly connected to the outer wall of the third gear 206. A stirring blade 208 is fixedly connected to the inner wall of the support plate 207. The outer wall of the stirring blade 208 is slidably connected to the inner wall of the housing 2.

[0030] Specifically, the first motor 201, protected by the outer casing 2, is activated. The first motor 201 drives the triangular rod 202 and the first gear 204 to rotate. During the rotation, the first gear 204 is pushed by the gear ring 203, which allows the first gear 204 to rotate on its own during operation. The rotation of the first gear 204 drives the second gear 205 to drive the third gear 206 to rotate, which limits the movement trajectory of the third gear 206 to prevent it from falling off. The rotation of the third gear 206 drives the support plate 207 and the stirring blade 208 to rotate, which continuously stirs the liquid to be tested, making the liquid flow continuously and preventing sedimentation.

[0031] Working principle: When the device is needed, the liquid to be tested is placed into the outer casing 2, and then the first motor 201 supported by the outer casing 2 is started. The first motor 201 drives the triangular rod 202 and the first gear 204 to rotate. During the movement, the first gear 204 is pushed by the gear ring 203, which enables the first gear 204 to rotate on its own. The first gear 204 drives the second gear 205 to drive the third gear 206 to rotate, which restricts the movement trajectory of the third gear 206 to prevent it from falling off. The third gear 206 drives the support plate 207 and the stirring blade 208. The rotation continuously stirs the liquid to be tested, preventing sedimentation. After placing the liquid into the outer casing 2, the test tube is placed on the stage 10. Then, the first rotating rod 304 and the third motor 4 on the support plate 3 are activated. The second motor 301 drives the rotating plate 302 and the sliding column 303 to rotate. The rotation of the rotating plate 302 pushes the first rotating rod 304 to rotate in the fixed plate 305, which restricts the movement trajectory of the first rotating rod 304 to prevent deviation. The movement of the first rotating rod 304 drives the second rotating rod 306 to slide the slider 307, thus restricting the movement of the slider 307. The movement trajectory prevents deviation. The movement of slider 307 drives the rotating column 308 and rotating rod 309 to move. The movement of rotating rod 309 drives the liquid-collecting head 310 and infusion head 311 to move, enabling the rotating rod 309 to move vertically. The rotation of slider 303 pushes the rotating column 308 to rotate, which in turn drives the liquid-collecting head 310 and infusion head 311 to rotate. This ensures that the pipetting assembly can rotate during the lifting and lowering process, preventing the test tube from hitting the inner wall of the container and enabling automatic injection. Simultaneously, the rotation of the second motor 301 is accompanied by the start of the rotation of the third motor 4. The third motor 4 drives the sector tooth 5 to push the first rack 6 to slide on the slide table 9, which restricts the movement trajectory of the first rack 6 to prevent deviation. After the first rack 6 drives the stage 10 to the end, the sector tooth 5 will push the second rack 8 to compress the connecting column 7, which enables the second rack 8 to quickly reset and facilitates multiple uses. During use, this device can not only enable the pipetting assembly to rotate during the lifting process so that the test tube does not touch the inner wall of the container and can automatically inject, but also continuously stir the liquid to be tested, so that the liquid flows continuously and prevents sedimentation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
