[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying 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.

[0034] Please refer to Figures 1 to 5 simultaneously. Now, an automatic identification device for culture dishes of a floating bacteria sampling robot provided by the present utility model will be described. The automatic identification device for culture dishes of a floating bacteria sampling robot is arranged on the top of the sampling workbench 1. The automatic identification device for culture dishes includes a stacking rack 2, a manipulator 3 and a rotating table 4; the stacking rack 2 has a storage space for stacking culture dishes 5 in the height direction; the manipulator 3 is arranged on the sampling workbench 1; the manipulator 3 is used to grab the culture dishes 5 on the stacking rack 2; the rotating table 4 is rotatably arranged on the top of the sampling workbench 1; the sampling workbench 1 is provided with an identification module 6 facing the rotating table 4; wherein, the rotating table 4 is used to receive the culture dishes 5 grabbed by the manipulator 3, and the rotating table 4 can drive the culture dishes 5 to rotate to a position where the identification code is aligned with the identification module 6.

[0035] Compared with the prior art, the automatic identification device for culture dishes 5 of a floating bacteria sampling robot provided by the present utility model grabs the culture dishes 5 on the stacking rack 2 by the manipulator 3, and then places the culture dishes 5 on the rotating table 4; by driving the culture dishes 5 to rotate by the rotating table 4, the identification code on the culture dishes 5 can be aligned with the identification module 6, which is convenient for the identification module 6 to read the information of the culture dishes 5 and input it into the system; through the above settings, the function of automatic identification can be realized, the degree of automation is high, and the labor intensity of the operator can be reduced.

[0036] Exemplarily, a plurality of culture dishes 5 are stacked in the height direction on the stacking rack 2, and the manipulator 3 only grabs one culture dish 5 each time; through the above settings, the operator only needs to place the stacking rack 2 full of culture dishes 5 on the sampling workbench 1 to realize automatic sampling, which can reduce the operation steps of the operator and reduce the labor intensity.

[0037] In addition, both the manipulator 3 and the identification module 6 are prior arts and will not be elaborated here.

[0038] In some embodiments, as Figures 1 to 5 shown, the bottom of the culture dish 5 has a concave cavity 51, the top of the culture dish 5 has a connecting cylinder 52 protruding into the concave cavity 51, the bottom of the connecting cylinder 52 has a plurality of air holes 53, and the diameter of the air holes 53 is smaller than the diameter of the collected sample; the rotating table 4 is inserted and matched with the concave cavity 51; the rotating table 4 is provided with a pressing mechanism 7 for pressing against the inner peripheral wall of the concave cavity 51. The culture dish 5 has a dust-proof cover 54, and the dust-proof cover 54 is removed during sampling.

[0039] It should be noted that after the manipulator 3 places the culture dish 5 on the rotating table 4, the rotating table 4 is inserted and cooperated with the concave cavity 51, and the rotating table 4 does not contact the connecting cylinder 52; after the culture dish 5 is tightened by the tightening mechanism 7, the manipulator 3 is separated from the culture dish 5. At this time, the rotating table 4 drives the culture dish 5 to rotate, and the identification code on the culture dish 5 can be rotated to a position aligned with the identification module 6, so as to facilitate the identification module 6 to identify the identification code of the culture dish 5; after the code scanning is completed, the manipulator 3 takes away the culture dish 5 on the rotating table 4.

[0040] Exemplarily, a servo motor 8 is provided on the sampling workbench 1, and the output shaft of the servo motor 8 is connected to the bottom of the rotating table 4; by driving the rotating table 4 to rotate through the servo motor 8, the culture dish 5 can be driven to rotate.

[0041] In some embodiments, as Figures 1 to 5 shown, the tightening mechanism 7 includes an elastic sleeve 71, and the elastic sleeve 71 is sleeved on the outer peripheral wall of the rotating table 4; there is a connection structure between the elastic sleeve 71 and the outer peripheral wall of the rotating table 4; wherein, the elastic sleeve 71 is used to tighten the inner peripheral wall of the concave cavity 51 of the culture dish 5; the connection structure includes a collar 72, and the collar 72 is connected to the outer peripheral wall of the rotating table 4; an annular groove 73 that is inserted and cooperated with the collar 72 is provided on the inner peripheral wall of the elastic sleeve 71.

[0042] It should be noted that by sleeving the elastic sleeve 71 on the outer peripheral wall of the rotating table 4 and inserting and cooperating the annular groove 73 on the elastic sleeve 71 with the collar 72, the elastic sleeve 71 can be fixed on the rotating table 4; during the insertion process of the culture dish 5 and the rotating table 4, the elastic sleeve 71 can undergo elastic deformation and tighten the inner peripheral wall of the culture dish 5, so as to facilitate the rotating table 4 to drive the culture dish 5 to rotate.

[0043] In some embodiments, as Figures 1 to 5 shown, the top edge position of the elastic sleeve 71 has a guiding inclined surface 74, and the area of the top of the elastic sleeve 71 is smaller than the area of the bottom of the elastic sleeve 71.

[0044] It should be noted that by providing the guiding inclined surface 74 at the top edge of the elastic sleeve 71, the guiding inclined surface 74 can first enter the culture dish 5, and then the outer peripheral wall of the elastic sleeve 71 undergoes elastic deformation, so that the outer peripheral wall of the elastic sleeve 71 tightens the inner peripheral wall of the culture dish 5.

[0045] In some embodiments, as Figures 1 to 5As shown, there are several tightening mechanisms 7, and the several tightening mechanisms 7 are arranged at intervals along the circumferential direction of the rotating table 4; each tightening mechanism 7 includes a tightening portion 75 and a driving structure 76; the tightening portion 75 is slidably arranged at the bottom of the rotating table 4; one end of the tightening portion 75 has a first state for tightening the inner peripheral wall of the concave cavity 51 and a second state separated from the inner peripheral wall of the concave cavity 51; the driving structure 76 is arranged at the bottom of the rotating table 4; the driving end of the driving structure 76 is connected to the other end of the tightening portion 75.

[0046] It should be noted that one of the tightening mechanisms 7 is taken as an example for description in this embodiment; after the manipulator 3 inserts the culture dish 5 into the rotating table 4, by driving the driving structure 76 to drive the tightening portion 75 to slide outwards, the tightening portion 75 can be made to tighten the inner peripheral wall of the culture dish 5, and thus the culture dish 5 can be fixed on the rotating table 4; after the scanning code is completed, the manipulator 3 grabs the culture dish 5, and at this time the driving structure 76 drives the tightening portion 75 to reset, which is convenient for the manipulator 3 to take out the culture dish 5 from the rotating table 4. The angle by which the driving structure 76 drives the rotating table 4 to rotate is less than 360 degrees. After the scanning code ends, the manipulator 3 takes away the culture dish 5, and the driving structure 76 drives the rotating table 4 to reset.

[0047] Exemplarily, the driving structure 76 includes a driving cylinder, the cylinder body of the driving cylinder is fixed at the bottom of the rotating table 4, and the piston rod of the driving cylinder is connected to the tightening portion 75.

[0048] In some embodiments, as Figures 1 to 5 shown, a U-shaped plate 41 is connected to the bottom of the rotating table 4, and a chute is formed between the U-shaped plate 41 and the bottom of the rotating table 4, and the tightening portion 75 is slidably engaged with the chute.

[0049] It should be noted that by arranging the U-shaped plate 41 at the bottom of the rotating table 4, it can play a role in limiting the sliding of the tightening portion 75, and at the same time the U-shaped plate 41 can also play a role in supporting the tightening portion 75.

[0050] In some embodiments, as Figures 1 to 5 shown, the tightening end of the tightening portion 75 has an elastic pad (not shown in the figure), and the elastic pad is used to contact the inner peripheral wall of the concave cavity 51.

[0051] It should be noted that by arranging the elastic pad at the tightening end of the tightening portion 75, the situation that the tightening portion 75 scratches the culture dish 5 can be reduced.

[0052] 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.
