[0031] Embodiment:

[0032] As Figure 1 and Figure 5 shown, Figure 1 FIG. 1 is a schematic structural diagram of the automatic transfer device according to an embodiment of the present invention; Figure 5 FIG. 2 is a diagram showing the usage state of the automatic transfer device according to an embodiment of the present invention; An automatic transfer device for an electronic irradiation biological experiment includes a lifting mechanism 1; a base 2 is fixedly provided on the lifting mechanism 1, a slider 3 is arranged along the length direction of the base 2, and a driving mechanism 8 for driving the slider 3 to move is installed on one side of the base 2; a slide table 4 is fixedly provided on the slider 3, a plurality of positioning grooves 5 for fixing culture dishes are formed on the slide table 4, a flip-up protective cover 6 is installed on the base 2, and a through hole 7 adapted to the positioning groove 5 is formed on the protective cover 6.

[0033] The assembly method of the present invention is as follows:

[0034] First, build a lifting mechanism 1 that can be electrically controlled to move up and down to ensure the stable and reliable lifting function of the lifting mechanism 1. Install the base 2 on the lifting mechanism 1 to ensure the levelness and installation firmness of the base 2.

[0035] Secondly, install a driving motor 82 on the base 2 and correctly connect the gear-rack transmission system to ensure that the driving motor 82 can smoothly drive the slide table 4 to translate.

[0037] Finally, design and install a flip-up protective cover 6, and make a through hole 7 of a suitable size on the protective cover 6 to ensure that the through hole 7 can accurately guide the irradiation light onto the culture dish.

[0038] The structure of the present invention is simple, realizing the automatic transfer of culture dishes and improving the efficiency of electronic irradiation biological experiments; compared with traditional manual operations, the experimental time is greatly shortened; the design of the present invention is ingenious, and through the automatic transfer device, the opportunity for personnel to directly contact the irradiation environment is reduced, the risk of irradiation injury to operators is reduced, and the health and safety of personnel are guaranteed.

[0039] As Figure 2 shown, Figure 2It is a schematic structural diagram of the lifting mechanism in the embodiment of the present utility model; specifically, the lifting mechanism 1 includes a bottom support frame 10, a top lifting frame 11, and a scissor 12 arranged in a cross shape; the scissor 12 arranged in a cross shape is located between the bottom support frame 10 and the top lifting frame 11; the scissor 12 arranged in a cross shape is slidably connected to the bottom support frame 10 and the top lifting frame 11, and the top lifting frame 11 always remains horizontally arranged.

[0040] The bottom support frame 10 and the top lifting frame 11 form the bottom and top of the lifting mechanism 1, and both the bottom support frame 10 and the top lifting frame 11 always remain in a horizontal state. During the movement of the scissor 12, the scissor 12 supports the top lifting frame 11, thereby playing a role in lifting.

[0041] The scissors 12 are symmetrically arranged on both sides of the bottom support frame 10 and the top lifting frame 11, and a rotating shaft 13 is connected between the symmetrically arranged scissors 12; the scissors 12 include a first diagonal brace 12-1 and a second diagonal brace 12-2 arranged in a cross shape, and the middle parts of the first diagonal brace 12-1 and the second diagonal brace 12-2 are rotatably connected through the rotating shaft 13.

[0042] The first diagonal brace 12-1 and the second diagonal brace 12-2 on the same side are arranged in an overlapping manner, and the symmetrically arranged scissors 12 are connected by a rotating shaft 13, and the rotating shaft 13 always remains horizontally arranged. Under the action of the rotating shaft 13, the first diagonal brace 12-1 and the second diagonal brace 12-2 are rotatably connected.

[0043] Both ends of the first diagonal brace 12-1 are respectively connected to the bottom support frame 10 and the top lifting frame 11. The bottom of the first diagonal brace 12-1 is slidably connected to the bottom support frame 10, and the top of the first diagonal brace 12-1 is rotatably connected to the top lifting frame 11; both ends of the second diagonal brace 12-2 are respectively connected to the bottom support frame 10 and the top lifting frame 11. The bottom of the second diagonal brace 12-2 is rotatably connected to the bottom support frame 10, and the top of the second diagonal brace 12-2 is slidably connected to the top lifting frame 11.

[0044] A bottom chute 14 adapted to the scissor 12 is provided inside the bottom support frame 10, and a top chute 15 adapted to the scissor 12 is provided inside the top lifting frame 11. A second rotating rod 22 is rotatably connected to the top of the second diagonal brace 12-2, and the second rotating rod 22 is clamped in the top chute 15. A connecting member 17 is installed in the middle of the second rotating rod 22, and an adjusting screw rod 18 is passed through the connecting member 17. The adjusting screw rod 18 is connected to a lifting motor 19, and the lifting motor 19 is located at the bottom of the top lifting frame 11.

[0045] During use, the lifting motor 19 drives the adjusting lead screw 18 to rotate. At the same time, the adjusting lead screw 18 drives the first rotating rod 14 to rotate through rotation. Since both ends of the first rotating rod 14 are clamped in the top chute 15, the first rotating rod 14 moves left and right along the top chute 15, driving the entire lifting mechanism 1 to rise. At the same time, the top chute 15 limits the stroke of the first rotating rod 14 to prevent the first rotating rod 14 from sliding excessively and affecting the balance of the lifting mechanism 1. Specifically, gears are formed at both ends of the first rotating rod 14, and racks meshing with the gears are installed at the upper and lower ends in the top chute 15. In this way, the lifting motor 19 can drive the adjusting lead screw 18 to rotate, so that the first rotating rod 14 moves along the top chute 15, driving the entire lifting mechanism 1 to rise.

[0046] A support shaft 16 is fixedly provided at the bottom of the first diagonal brace 12-1. Both ends of the support shaft 16 are located in the bottom chute 14 and move back and forth along the bottom chute 14. By pushing or pulling the first diagonal brace 12-1, the angle between the first diagonal brace 12-1 and the second diagonal brace 12-2 becomes smaller, so that the tops of the second diagonal brace 12-2 and the first diagonal brace 12-1 rise, realizing the rise of the top lifting frame 11.

A through hole adapted to the positioning groove is formed on the protective cover, which can not only accurately irradiate the irradiation light onto the target culture dish, but also effectively protect other culture dishes from unnecessary irradiation, ensuring the scientificity and rigor of the experiment.

[0049] A plurality of positioning grooves 5 are arranged equidistantly along the length direction of the slide table 4; the design of a plurality of culture dish positioning grooves on the slide table of the present invention and the precise control of the motor can ensure that each culture dish can accurately move to the irradiation position, improving the accuracy and repeatability of the experiment.

[0050] A groove 20 is arranged along the length direction of the base 2, and the slider 3 is placed in the groove 20; this makes the movement of the slider 3 and the slide table 4 stable and safe.

[0051] The slider 3 is the same length as the slide table 4, and the length of the slider 3 is 1 / 2 to 1 / 3 of the length of the base 2; in this embodiment, the length of the slider 3 is 1 / 2 of the length of the base 2.
