[0025] The loading and unloading mechanism 10 of the colony detection device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figures 1-3 As shown, the loading and unloading mechanism 10 of the colony detection device according to an embodiment of the present invention includes a base 100, a turntable 200 and a positioning component 300.

[0027] A drive block 110 is provided inside the base 100, and the drive block 110 is located directly below the colony counter 20 (the vertical direction is shown by the arrow in the figure). The turntable 200 is rotatably mounted on the base 100. Multiple positioning components 300 are vertically and vertically mounted on the turntable 200 and are spaced apart around the circumference of the turntable 200. Each positioning component 300 is suitable for placing a culture dish. The positioning component 300 is configured to rise under the drive of the drive block 110 and clamp the culture dish when the turntable 200 rotates above it.

[0028] Specifically, the colony detection device 1 includes a loading and unloading mechanism 10 and a colony counter 20. The colony counter 20 is mounted above the loading and unloading mechanism 10 via a bracket 21.

[0029] During testing, the turntable 200 rotates, causing the positioning component 300 to rotate as well. When the positioning component 300 rotates to a position directly above the drive block 110, it is positioned directly below the colony counter 20. The drive block 110 then drives the positioning component 300 to rise and clamp the culture dish, bringing it closer to the colony counter 20 for colony detection. After the detection is complete, the turntable 200 rotates again, causing the positioning component 300 to rotate as well. This lowers the culture dish that has been tested and removes it from below the colony counter 20, while another culture dish rotates to be tested below the colony counter 20, enabling continuous testing and improving testing efficiency.

[0030] According to the colony detection device of this utility model embodiment, the loading and unloading mechanism 10 is equipped with a drive block 110, a turntable 200, and multiple positioning components 300. The positioning components 300 are configured to rise and clamp the culture dish under the drive of the drive block 110 when the turntable 200 rotates above the drive block 110. When the positioning components 300 rotate to directly above the drive block 110, the culture dish can be raised and clamped. This allows the culture dish to be brought closer to the colony counter 20 and can also be positioned, facilitating colony detection by the colony counter 20 and improving the accuracy of colony detection. After detection, the culture dish can be removed by rotating the turntable 200, and the undetected culture dish can be rotated to be detected below the colony counter 20. Compared with colony detection devices in related technologies, this device eliminates the need for frequent release and clamping of the clamping device, enabling automatic and continuous loading and unloading of culture dishes, continuous colony detection, and improved detection efficiency.

[0031] Therefore, the loading and unloading mechanism 10 of the colony detection device according to the present invention has the advantages of high detection efficiency.

[0032] The loading and unloading mechanism 10 of a colony detection device according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0033] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the loading and unloading mechanism 10 of the colony detection device according to an embodiment of the present invention includes a base 100, a turntable 200 and a positioning component 300.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, a base plate 120 is provided inside the base 100, and a drive block 110 is provided on the base plate 120 and protrudes upward. The drive block 110 is eccentrically set on the base plate 120. A push rod 310 is connected below the positioning component 300. When the positioning component 300 rotates with the turntable 200 to above the drive block 110, the drive block 110 lifts the push rod 310. This facilitates the drive block 110 to drive the positioning component 300 to rise.

[0035] More specifically, such as Figure 2 As shown, the drive block 110 is triangular, with rounded transitions at the connection between the drive block 110 and the base plate 120, as well as at the vertices of the triangle. A roller 311 is connected to the lower end of the push rod 310. This design allows the inclined surface of the drive block 110 to convert the rotation of the turntable 200 into a driving force for lifting the push rod 310. Furthermore, it ensures smoother contact between the push rod 310 and the surface of the drive block 110, reducing friction and resistance, and facilitating smooth rotation of the turntable 200.

[0036] Figure 2 and Figure 3 The loading and unloading mechanism 10 of a colony detection device according to some examples of the present invention is shown. For example... Figure 2 and Figure 3 As shown, the turntable 200 has multiple guide grooves 210, and a through groove 220 is provided between the guide grooves 210 and the upper surface of the turntable 200. Each positioning component 300 includes a guide rod 320, two sliders 330, two clamping blocks 340, a horizontal connecting rod 350, and two inclined connecting rods 360. The guide rod 320 is adapted to pass through the through groove 220. The two sliders 330 are movably mounted on the guide rod 320. The two clamping blocks 340 are respectively mounted on the two sliders 330, and the two clamping blocks 340 are adapted to jointly clamp the culture dish. The horizontal connecting rod 350 is vertically and vertically mounted in the guide groove 210. The horizontal connecting rod 350 is oriented in the horizontal direction. When the positioning component 300 rotates with the turntable 200 to above the drive block 110, the drive block 110 lifts the horizontal connecting rod 350. The length of the horizontal connecting rod 350 is greater than the length of the guide rod 320. The lower ends of the two inclined connecting rods 360 are pivotally connected to the two ends of the horizontal connecting rod 350, respectively, and the upper ends of the two inclined connecting rods 360 are pivotally connected to the two sliders 330, respectively. The upper ends of the two inclined connecting rods 360 are adapted to pass through the through groove 220 and are configured such that, during the upward movement of the horizontal connecting rod 350, the upper ends of the two inclined connecting rods 360 approach each other under the constraint of the through groove 220. Specifically, the push rod 310 is connected to the lower surface of the horizontal connecting rod 350. During the rotation of the turntable 200, the drive block 110 lifts the horizontal connecting rod 350. During the upward movement of the horizontal connecting rod 350, the inclined connecting rods 360 rise together with the horizontal connecting rod 350. Since the size of the through groove 220 remains unchanged, the upper ends of the two inclined connecting rods 360 gradually approach each other under the constraint of the through groove 220, causing the two sliders 330 to approach each other under the guidance of the guide rod 320, thereby driving the two clamping blocks 340 to approach each other, thus achieving the clamping of the culture dish. This makes it easier for the positioning component 300 to hold the culture dish during the ascent.

[0037] Advantageously, such as Figure 2 and Figure 3As shown, a reset elastic element 370 is provided between the guide rod 320 and the horizontal connecting rod 350. This allows the positioning assembly 300, after the culture dish has been inspected, to rotate with the turntable 200 until it is misaligned with the drive block 110. The horizontal connecting rod 350 then moves downwards and resets under the elastic force of the reset elastic element 370. This facilitates re-lifting when rotating back to the drive block 110 and also allows for easy release of the culture dish, making it convenient to replace the inspected culture dish.

[0038] Specifically, such as Figure 2 and Figure 3 As shown, a spring guide rod 371 is provided on the horizontal connecting rod 350, and the reset elastic element 370 is a spring and is sleeved on the spring guide rod 371. This not only facilitates the installation of the reset elastic element 370, but also allows the spring guide rod 371 to position and guide the reset elastic element 370, preventing the reset elastic element 370 from bending or shifting.

[0039] Optionally, such as Figure 2 and Figure 3 As shown, the seat plate 120 is vertically and flexibly disposed within the base 100, and a lifting drive device 130 for driving the seat plate 120 to rise and fall is provided below the seat plate 120. In this way, when it is not necessary to lift the positioning component 300, the lifting drive device 130 can drive the seat plate 120 to fall, causing the drive block 110 to fall to avoid the positioning component 300. When it is necessary to lift the positioning component 300, the seat plate 120 can be driven to rise, causing the drive block 110 to rise so as to lift the positioning component 300.

[0040] More specifically, such as Figure 3 As shown, a rotation drive device 140 is provided on the base plate 120, and the rotation drive device 140 is connected to the turntable 200 for transmission. This facilitates the rotation of the turntable 200.

[0041] Advantageously, such as Figure 2 and Figure 3 As shown, one of the rotary drive device 140 and the turntable 200 is provided with a sleeve 141 and the other is provided with a sleeve rod 142. The sleeve 141 is axially movable and is fitted around the sleeve rod 142 while restricting circumferential relative rotation. This allows the rotary drive device 140 to rise and fall together with the seat plate 120 while ensuring the transmission of driving force from the rotary drive device 140 to the turntable 200.

The colony detection device 1 according to an embodiment of the present invention includes a loading and unloading mechanism 10 according to the colony detection device of the above embodiment of the present invention.

[0043] Specifically, the colony detection device 1 includes a loading and unloading mechanism 10 and a colony counter 20. The colony counter 20 is mounted above the loading and unloading mechanism 10 via a bracket 21.
