Detailed Description of the Embodiment

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer to Figures 1 to 5, a feeding assembly for a planktonic bacteria sampling robot provided by the utility model is now described. The feeding assembly for a planktonic bacteria sampling robot is arranged on a sampling workbench 1, and the sampling workbench 1 has a sampling port. The feeding assembly includes a stacking rack 2, a manipulator 3 and a connecting structure 4; the stacking rack 2 includes a bottom plate 21 and a plurality of support rods 22 connected to the top of the bottom plate 21, and each support rod 22 is arranged along the height direction; a placement space for placing a culture dish is formed between the plurality of support rods 22; the manipulator 3 is arranged on the sampling workbench 1; the manipulator 3 is used to grab the culture dish on the stacking rack 2, and the manipulator 3 can place the culture dish at the sampling port of the sampling workbench 1; the connecting structure 4 is arranged on the sampling workbench 1; the connecting structure 4 is used to connect with the bottom plate 21 to locate the position of the stacking rack 2.

[0030] The utility model provides a feeding assembly for a planktonic bacteria sampling robot. Compared with the prior art, a plurality of culture dishes can be stacked on a stacking rack 2. The culture dishes on the stacking rack 2 are grabbed by a manipulator 3 and placed at a sampling port of a sampling workbench 1. Therefore, there is no need for an operator to frequently load the materials, thereby reducing the labor intensity of the operator. The stacking rack 2 is connected to the sampling workbench 1 through a connecting structure 4, which can strengthen the connection between the stacking rack 2 and the sampling workbench 1. When the manipulator 3 clamps the culture dishes from the stacking rack 2, the separation of the stacking rack 2 and the sampling workbench 1 can be reduced, thereby improving stability.

[0031] In some embodiments, Figures 1 to 5 As shown, the connection structure 4 includes a positioning protrusion 41 connected to the sampling workbench 1, and the bottom of the bottom plate 21 has a groove 23 that is plugged into and matched with the positioning protrusion 41. The side of the positioning protrusion 41 is an inclined surface 411, and the area of ​​the top of the positioning protrusion 41 is smaller than the area of ​​the bottom of the positioning protrusion 41; wherein, the outer peripheral wall of the positioning protrusion 41 is connected with an elastic layer, and the elastic layer is used to contact the inner peripheral wall of the groove 23.

[0032] It should be noted that when the stacking rack 2 is placed on the sampling workbench 1, the positioning protrusion 41 and the groove 23 are plugged in and matched, so as to position the stacking rack 2; by providing a slope 411 on the side of the positioning protrusion 41, and providing an elastic layer on the outer peripheral wall of the positioning protrusion 41, after the bottom plate 21 is plugged in and matched with the positioning protrusion 41, the elastic layer can abut against the inner peripheral wall of the groove 23, thereby fixing the position of the stacking rack 2 and improving the connection strength between the stacking rack 2 and the sampling workbench 1.

[0033] In some embodiments, Figures 1 to 5As shown, the bottom plate 21 is provided with a plurality of jacks 24 around the groove 23. The connecting structure 4 further includes plugging components 42 corresponding to the jacks 24 one by one. The plugging components 42 have an outward expanding elastic force. When the plugging components 42 are plugged and matched with the jacks 24, the plugging components 42 abut against the inner peripheral wall of the jacks 24.

[0034] It should be noted that, since the plugging components 42 have an outward expanding elastic force, after the plugging components 42 are plugged and matched with the jacks 24, the plugging components 42 can abut against the inner peripheral wall of the jacks 24 under the action of their own elastic force, which can further strengthen the connection strength between the stacking rack 2 and the sampling workbench 1.

[0035] In some embodiments, as Figures 1 to 5 shown, each plugging component 42 includes a plurality of elastic pieces 421. The plurality of elastic pieces 421 are arranged at intervals in the circumferential direction. There is a deformation gap between adjacent elastic pieces 421. Among them, the diameter of the plurality of elastic pieces 421 in the initial state is greater than the diameter of the jack 24. The opening of the jack 24 on the bottom plate 21 has a flared opening 241 to guide the plurality of elastic pieces 421. The top of each elastic piece 421 has a conical surface 422, and the conical surface 422 of the elastic piece 421 inclines inward in the direction towards the top, so that the diameter enclosed by the smallest end of the conical surface 422 is smaller than the diameter of the jack 24.

[0036] It should be noted that, since the diameter of the elastic pieces 421 in the initial state is greater than the diameter of the jack 24, after the elastic pieces 421 are plugged and matched with the jack 24, the elastic pieces 421 have an outward expanding elastic force, that is, the elastic pieces 421 will abut against the inner peripheral wall of the jack 24 and fix the stacking rack 2 on the sampling workbench 1. By providing a flared opening 241 on the jack 24 and a conical surface 422 at the top of the elastic piece 421, the top of the elastic piece 421 can be inserted into the jack 24, and then the elastic piece 421 undergoes elastic deformation in the jack 24, so that the elastic piece 421 abuts against the inner peripheral wall of the jack 24.

[0037] In some embodiments, as Figures 1 to 5 shown, each plugging component 42 further includes a connecting plate 423. The connecting plate 423 is located at the bottom of the elastic piece 421 and is connected to the plurality of elastic pieces 421. The connecting plate 423 is detachably connected to the sampling workbench 1. The sampling workbench 1 is provided with a threaded hole, and the connecting plate 423 has a stud 424 that is threadedly engaged with the sampling workbench 1.

[0038] It should be noted that the connecting plate 423 is connected to the sampling workbench 1 through the stud 424, which facilitates the disassembly and assembly of the connecting plate 423. After the elastic piece 421 is damaged, it is convenient to replace.

[0039] In some embodiments, as Figures 1 to 5As shown in the figure, there are at least two stacking racks 2, one of which is a loading rack and the other is an unloading rack; there is an avoidance space on the stacking rack 2 for the plug-in fit of the manipulator 3.

[0040] It should be noted that the manipulator 3 can place the culture dish on the loading rack at the sampling port position of the sampling workbench 1. After sampling, the manipulator 3 can place the culture dish on the unloading rack. By setting an avoidance space on the stacking rack 2, it is convenient for the manipulator 3 to pick up and place the culture dish from the stacking rack 2.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
