In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0034] The utility model will be further described below in conjunction with the accompanying drawings.

[0035] like Figure 1-8 As shown, a labeling mechanism for a culture dish and a sample tube comprises: a base 1; a label grabbing mechanism, which is installed on the base 1, and whose grabbing end can not only rotate but also move back and forth between a label grabbing position and a labeling position; a clamping mechanism (not shown in the figure), which is used to clamp a test tube or a culture dish and move it to the labeling position; a baffle mechanism, which is arranged above the labeling position and is used to open the cover of the culture dish; a control unit, which controls the working states of the label grabbing mechanism and the clamping mechanism according to the labeling object; when the labeling object is a culture dish, the grabbing end of the label grabbing mechanism is kept horizontally arranged and moves from the label grabbing position to the labeling position of the culture dish, and at the same time, the clamping mechanism clamps a culture dish and moves it to the position of the baffle mechanism to open the cover, and after opening the cover, the clamping mechanism moves the culture dish to the labeling position, and the label grabbing mechanism labels the culture dish;

[0036] When the labeling object is a sample tube, the grabbing end of the label grabbing mechanism rotates 90° and then remains vertically set, and moves from the label grabbing position to the labeling position of the sample tube. At the same time, the clamping mechanism clamps a sample tube and moves it to the labeling position, and the label grabbing mechanism labels the sample tube.

[0037] Specifically, the base 1 includes a bottom plate and a vertical plate, wherein the bottom plate is horizontally arranged and the vertical plate is vertically arranged. Preferably, the bottom plate and the vertical plate are connected as one body.

[0038] The label grabbing mechanism includes: a first swing arm 2, a first rotating shaft 3, a second rotating shaft 4, a second swing arm 5, a motor 12 and a suction cup mechanism; the first rotating shaft 3 is rotatably connected to the base 1, the lower end of the first swing arm 2 is sleeved on the first rotating shaft 3, the upper end of the first swing arm 2 is rotatably sleeved on the second rotating shaft 4, one end of the second rotating shaft 4 is connected to the lower end of the second swing arm 5 and sleeved on the second rotating shaft 4, and the suction cup mechanism is arranged at the front end of the second swing arm 5; the output end of the motor 12 is connected to the first rotating shaft 3 through a transmission mechanism, and the control unit is electrically connected to the motor 12. Among them, the motor 12 is installed on the vertical plate of the base 1, and the transmission mechanism connected to its output end can be a belt drive, etc., such as connecting a driving wheel to the output end of the motor 12, connecting a driven wheel to the first rotating shaft 3, and connecting the driving wheel and the driven wheel through a transmission belt, so that the rotation of the motor 12 drives the rotation of the first rotating shaft.

[0039] The label grabbing mechanism also includes: a first synchronous wheel 6 , a second synchronous wheel 7 and a synchronous belt 8 ; the first synchronous wheel 6 is connected to the first rotating shaft 3 , the second synchronous wheel 7 is connected to the second rotating shaft 4 , and the first synchronous wheel 6 and the second synchronous wheel 7 are connected via a synchronous belt 8 .

[0040] The suction cup mechanism comprises: a suction cup 9 and a rotating cylinder 10 ; the movable end of the rotating cylinder 10 is connected to the suction cup 9 , and the fixed end of the rotating cylinder 10 is connected to the front end of the second swing arm 5 .

[0041] The label grabbing mechanism further includes a limiting mechanism, which includes a spring 13 , one end of which is connected to the first synchronous wheel 6 , and the other end of which is connected to the base 1 .

[0042] The baffle mechanism includes a horizontally arranged baffle 11 and a vertically arranged L-shaped plate, and the baffle 11 is connected to the vertical plate of the base 1 through the L-shaped plate. Figure 2 As shown, the baffle 11 is located at the rear side of the label grabbing mechanism, and the baffle 11 is higher than the labeling position of the culture dish.

[0043] In this embodiment, the labels of the culture dish and the sample tube are printed by the same printer device, that is, the label grabbing position of the two is the same position. The culture dish and the sample tube are stored in different positions before labeling, that is, the clamping position of the sample tube and the culture dish is not the same position. The clamping mechanism moves to the corresponding storage position to clamp the labeling object according to the instruction of the control unit. Although the shapes of the culture dish and the sample tube are different, the clamping mechanism can be clamped by the same set of clamps, and when clamping, it is sufficient to leave the corresponding labeling area empty.

[0044] The labeling mechanism for the culture dish and the sample tube provided in this embodiment has the following working process:

[0045] First, the label printer prints out labels according to the labeling object and transfers the labels to a fixed grabbing position;

[0046] Next, the clamping mechanism clamps the labeling object to the labeling position;

[0047] If the labeling object is a culture dish, the clamping mechanism clamps the culture dish and moves to the top of the labeling position, and then moves downward, blocking the culture dish cover through the blocking piece 11, so as to open the cover and leave the side wall of the culture dish body (i.e., the labeling area), and then the label grabbing mechanism moves to label;

[0048] If the sample is a sample tube, the clamping mechanism directly clamps the sample tube and moves it to the labeling position, and then the label grabbing mechanism moves to perform labeling.

[0049] During the labeling process, the label grabbing mechanism absorbs the label through the negative pressure of the suction cup 9, and determines the next action according to the type of the labeling object: if the labeling object is a culture dish, the rotating cylinder 10 does not move, moves to the clamping position of the culture dish to directly label, and after labeling, the suction cup 9 is ventilated and released to complete the labeling; if the labeling object is a sample tube, the rotating cylinder 10 rotates 90°, and then moves to the clamping position of the culture dish to directly label, and after labeling, the suction cup 9 is ventilated and released to complete the labeling.

[0050] like Figure 3 and Figure 4 As shown, during the labeling process, the label grabbing mechanism realizes horizontal grabbing through two swing arms (the first swing arm 2 and the second swing arm 5), maintains the horizontal direction to realize labeling action, or rotates 90° to realize side wall labeling action. Although the labeling position of the culture dish and the labeling position of the sample tube are adjacent, they are not at the same position.

[0051] Before grabbing the label, the movement of the label grabbing mechanism can be divided into two stages: first, the first rotating shaft 3 is driven to rotate by the motor 12, and the first rotating shaft 3 drives the first synchronous wheel 6 to rotate in the same direction, and the first synchronous wheel 6 drives the second synchronous wheel 7 on the second rotating shaft 4 to move synchronously through the synchronous belt 8. Since the first synchronous wheel 6 on the first rotating shaft 3 is pulled by the spring 13, when the first swing arm 2 starts to rotate, the first synchronous wheel 6 does not rotate relative to the first swing arm 2, thereby driving the second synchronous wheel 7 on the second swing arm 5 to reverse. Since the second synchronous wheel 7 is fixed to the second swing arm 5, the second synchronous wheel 7 drives the second swing arm 5 to rotate in the opposite direction, completing the movement of the first stage; then, after the second swing arm 5 rotates to the limit position on the first swing arm 2, when the motor 12 continues to rotate, the second swing arm 5 does not move relative to the first swing arm 2, and the first synchronous wheel 6 pulls the spring 13 to move, so that the second swing arm 5 and the first swing arm 2 rotate as a whole.

[0052] like Figure 5 As shown, in the first stage, the second swing arm 5 and the first swing arm 2 rotate in opposite directions, and the two swing arms change from a folded state to an extended state. Figure 6As shown, in the second stage, the second swing arm 5 and the first swing arm 2 remain in an extended state and rotate in the same direction until the gripping end is able to grip the printed label.

[0053] After grabbing the label, the movement of the label grabbing mechanism is also divided into two similar stages. Figure 7 As shown in FIG. 1 , the second swing arm 5 and the first swing arm 2 continue to remain in the extended state and rotate in the same direction, but the rotation direction is exactly opposite to that of the second stage. Figure 8 As shown, then, the second swing arm 5 and the first swing arm 2 rotate in opposite directions, and the rotation direction is opposite to that of the first stage. The two swing arms change from an extended state to a folded state, and then remain in the folded state close to the labeling object.

[0054] In this way, the grabbing end of the label grabbing mechanism can avoid the table surface where the label is placed after grabbing the label, thereby avoiding position interference.

[0055] The labeling mechanism for the culture dish and the sample tube provided in this embodiment only needs one labeling station, and can realize automatic labeling of both the culture dish and the sample tube, thereby reducing the number of printers, improving the utilization rate, saving space, and reducing the manual workload.

[0056] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
