For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

As shown in Figures 1 to 3, the shaking module of the embodiment of the present invention includes a shaking substrate 1, a shaking plate 2, a suction cup 3, and a shaking drive assembly for driving the shaking plate 2 to rotate. The shaking plate 2 is arranged above the shaking substrate 1, and the suction cup 3 is arranged on the shaking plate 2. The shaking drive assembly includes an active crank wheel 4, a shaking motor 5, and a pair of driven crank wheels 6. The active crank wheel 4 and the pair of driven crank wheels 6 are arranged in an equilateral triangle on the shaking substrate 1. The shaking motor 5 is connected to the central axis of the active crank wheel 4, and the central axis of each driven crank wheel 6 is connected to the shaking substrate 1. A rotating wheel 8 is provided at the edge position of the active crank wheel 4 and each driven crank wheel 6, and each rotating wheel 8 is connected to the shaking plate 2 for rotation.

When in use, the suction cup 3 is used to adsorb and fix the bottom of the culture dish, and then the active crank wheel 4 can be driven by the shaking motor 5 to rotate around its central axis, thereby driving the shaking plate 2 and each driven crank wheel 6 to rotate under the action of each rotating wheel 8. Since the active crank wheel 4 and the two driven crank wheels 6 are arranged in an equilateral triangle, a double crank mechanism is formed between any two crank wheels and the shaking plate 2. Therefore, when the active crank wheel 4 rotates, it can drive the shaking plate 2 to perform orbital motion, thereby realizing the shaking action of the culture dish.

Therefore, the shaking module of the embodiment of the present invention can realize the automated operation of shaking the culture dish, which not only effectively improves the work efficiency, but also has a better shaking effect, thus meeting the needs of the modern food industry for food safety testing.

The shaking module of the embodiment of the present invention can not only be used to shake the culture medium and sample solution in the culture dish when pouring, but also can be used to suck the bottom of the culture dish for positioning when opening and closing the cover of the culture dish, and can also be used to suck the bottom of the culture dish to prevent rotation during coating.

Specifically, each rotating wheel 8 is rotationally connected to the active crank wheel 4 and each driven crank wheel 6 via a rotating shaft, and a rotating groove corresponding to each rotating wheel 8 is provided at the bottom of the shaking plate 2, and each rotating wheel 8 can be respectively embedded in each rotating groove for rotation.

The center lines of the rotating wheels 8 on the driving crank wheel 4 and the rotating wheels 8 on the driven crank wheels 6 form an equilateral triangle. That is, the double crank lengths of the double crank mechanism formed by any two crank wheels and the shake plate 2 in the driving crank wheel 4 and the two driven crank wheels 6 are equal, so as to ensure that the shake plate 2 is more stable and reliable when performing the revolution motion.

In some embodiments of the present invention, the shaking module also includes a suction cup lifting and landing assembly for controlling the vertical lifting of the suction cup 3, and the suction cup 3 is installed on the shaking plate 2 through the suction cup lifting and landing assembly. That is, by setting the suction cup lifting and landing assembly, the lifting and lowering action of the suction cup 3 can be controlled. Since during the inspection process, the culture dish is transported to the sample adding station through the station turntable, it is necessary to first adsorb the bottom of the culture dish through the suction cup 3 before shaking the culture dish, and then start the suction cup lifting and landing assembly to lift the culture dish so that the culture dish leaves the station hole of the station turntable, and then shake it again. When shaking, the suction cup lifting and landing assembly rotates synchronously with the shaking plate 2. When the shaking is completed, start the suction cup lifting and landing assembly again to drop the culture dish to the station hole of the station turntable, so that the subsequent station turntable can transfer the culture dish to the next station.

In a specific embodiment of the present invention, the suction cup lifting assembly 7 includes a slide cylinder 701, a slide column 702 and a lifting drive mechanism 703. The slide column 702 is disposed in the slide cylinder 701 and vertically slides with the slide cylinder 701. The upper end of the slide column 702 passes through the slide cylinder 701 and is fixedly connected to the bottom of the suction cup 3. The lifting drive mechanism 703 is drivingly connected to the lower end of the slide column 702. That is, the lifting drive mechanism 703 can drive the slide column 702 to move up and down along the slide cylinder 701, thereby driving the suction cup 3 to move up and down.

Among them, a mounting hole for the slide 701 to pass through is provided on the shake plate 2, and the outer wall of the slide 701 is fixedly connected to the shake plate 2 through the mounting hole, thereby realizing the support and installation of the lifting drive mechanism 703, so that when the shake plate 2 performs orbital motion, the lifting drive mechanism 703 can move synchronously with the shake plate 2.

A substrate through hole 101 is provided on the mixing substrate 1 for the slide 701 to freely pass through. When the mixing plate 2 revolves, the slide 701 can move synchronously with the mixing plate 2 within the range of the substrate through hole 101 .

Specifically, according to actual use requirements, the lifting drive mechanism 703 can adopt a linear drive mechanism such as a cylinder, a hydraulic cylinder or an electric push rod, as long as it can achieve up and down lifting drive control of the slide column 702.

Specifically, an air channel 704 is provided in the slide 701, and a suction hole 301 is provided at the center of the suction cup 3, and the suction hole 301 is connected to the air channel 704. An air suction connector 705 is also connected to one end of the air channel 704, and the air suction connector 705 is used to connect a negative pressure pump through a pipeline, thereby providing suction force for the suction cup 3.

In some embodiments of the present invention, a downwardly protruding suction cup connection column 302 is provided at the bottom of the suction cup 3, and the upper end of the slide column 702 is fixedly connected to the suction cup connection column 302. A lifting through hole is provided on the shaking plate 2 for the suction cup connection column 302 to freely pass through, and the suction cup connection column 302 vertically slides with the lifting through hole, so that the suction cup 3 can be lifted and lowered under the drive of the slide column 702.

In some embodiments of the present invention, the slide post 702 may be a cylindrical structure, and the inner cavity channel of the slide cylinder 701 is a circular channel adapted to the slide post 702. In order to prevent the slide post 702 from rotating in a circle in the slide cylinder 701, a limiting column 706 is fixed on the slide post 702, and a limiting groove 707 extending vertically is provided on the inner side wall of the slide cylinder 701. The limiting column 706 can slide up and down along the limiting groove 707, thereby limiting the slide post 702 to only move up and down in the slide cylinder 701.

Of course, other methods can be used to prevent the sliding column 702 from rotating in the sliding cylinder 701. For example, the cross section of the sliding column 702 is set to a triangular or quadrilateral structure, and the inner cavity channel of the sliding cylinder 701 is set to a triangular or quadrilateral structure that matches the cross section of the sliding column 702.

In some embodiments of the present invention, in order to ensure that the shaking plate 2 can smoothly perform the orbital shaking motion on the shaking substrate 1, the shaking motor 5 can be installed and fixed at the bottom of the shaking substrate 1, and the driving shaft of the shaking motor 5 can freely pass through the shaking substrate 1 and be driven and connected to the active crank wheel 4, thereby driving the active crank wheel 4 to rotate.

In some embodiments of the present invention, the shaking substrate 1 plays a role in supporting the entire shaking module. A mounting hole is provided on the shaking substrate 1 for mounting and fixing the shaking substrate 1 at a sample adding station below the station turntable.
