DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Example:

[0038] like Figure 1 and Figure 5 As shown, Figure 1 It is a structural schematic diagram of an automatic transfer device according to an embodiment of the present invention; Figure 5 It is a usage status diagram of the automatic transfer device of an embodiment of the present invention; an automatic transfer device for electron irradiation biological experiments, including a lifting mechanism 1; a base 2 is fixedly provided on the lifting mechanism 1, a slider 3 is arranged on the base 2 along its length direction, 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, and 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.

[0039] The assembly method of the present invention is as follows:

[0040] First, build a lifting mechanism 1 that can be electrically controlled to lift up and down, and ensure that the lifting function of the lifting mechanism 1 is stable and reliable. Install the base 2 on the lifting mechanism 1, and ensure the levelness and firmness of the base 2.

[0041] Secondly, the drive motor 82 is installed on the base 2 and the rack and pinion transmission system is correctly connected to ensure that the drive motor 82 can smoothly drive the slide 4 to translate.

[0042] Next, the slide 4 is mounted on the base 2 so that it can slide smoothly under the action of the gear rack; a suitable number and size of culture dish positioning grooves 5 are processed on the slide 4 to ensure that the culture dish can be firmly placed.

[0043] Finally, a retractable protective cover 6 is designed and installed, and a through hole 7 of a suitable size is made on the protective cover 6 to ensure that the through hole 7 can accurately guide the irradiation light to the culture dish.

[0044] The present invention has a simple structure, realizes the automatic transfer of the culture dish, and improves the efficiency of the electron irradiation biological experiment; compared with the traditional manual operation, the experimental time is greatly shortened; the present invention is cleverly designed, and through the automatic transfer device, the opportunity of direct contact between personnel and the irradiation environment is reduced, the risk of radiation injury to the operator is reduced, and the health and safety of the personnel is guaranteed.

[0045] like Figure 2 As shown, Figure 2 It is a structural schematic diagram of the lifting mechanism of an embodiment of the present invention; specifically, the lifting mechanism 1 includes a bottom supporting frame 10, a top lifting frame 11 and cross-arranged scissors forks 12; the cross-arranged scissors forks 12 are located between the bottom supporting frame 10 and the top lifting frame 11; the cross-arranged scissors forks 12 are slidably connected to the bottom supporting frame 10 and the top lifting frame 11, and the top lifting frame 11 always remains horizontally arranged.

[0046] The bottom support frame 10 and the top lifting frame 11 constitute the bottom and top of the lifting mechanism 1, and the bottom support frame 10 and the top lifting frame 11 are always in a horizontal state. During the movement of the scissors fork 12, the scissors fork 12 supports the top lifting frame 11, thereby playing a lifting role.

[0047] The scissors forks 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 forks 12; the scissors forks 12 include a first diagonal brace 12-1 and a second diagonal brace 12-2 that are cross-arranged, and the middle parts of the first diagonal brace 12-1 and the second diagonal brace 12-2 are rotatably connected by the rotating shaft 13.

[0048] 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 forks 12 are connected by a rotating shaft 13, and the rotating shaft 13 always remains in a horizontal state. Under the action of the rotating shaft 13, the first diagonal brace 12-1 and the second diagonal brace 12-2 are rotatably connected.

[0049] The two ends of the first diagonal brace 12-1 are respectively connected to the bottom supporting frame 10 and the top lifting frame 11, the bottom of the first diagonal brace 12-1 is slidably connected to the bottom supporting frame 10, and the top of the first diagonal brace 12-1 is rotatably connected to the top lifting frame 11; the two ends of the second diagonal brace 12-2 are respectively connected to the bottom supporting frame 10 and the top lifting frame 11, the bottom of the second diagonal brace 12-2 is rotatably connected to the bottom supporting frame 10, and the top of the second diagonal brace 12-2 is slidably connected to the top lifting frame 11.

[0050] The inner side of the bottom supporting frame 10 is provided with a bottom slide groove 14 adapted to the scissors fork 12, and the inner side of the top lifting frame 11 is provided with a top slide groove 15 adapted to the scissors fork 12.

The adjusting screw 18 is connected to a lifting motor 19, and the lifting motor 19 is located at the bottom of the top lifting frame 11.

[0051] During use, the lifting motor 19 drives the adjusting screw rod 18 to rotate, and at the same time, the adjusting screw rod 18 drives the first rotating rod 14 to rotate by rotating. Since the two ends of the first rotating rod 14 are clamped in the top slide groove 15, the first rotating rod 14 moves left and right along the top slide groove 15, driving the entire lifting mechanism 1 to rise. At the same time, the top slide groove 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 gears are installed at the upper and lower ends of the top slide groove 15. In this way, the lifting motor 19 can be used to drive the adjusting screw rod 18 to rotate, thereby making the first rotating rod 14 move along the top slide groove 15, driving the entire lifting mechanism 1 to rise.

[0052] A support shaft 16 is fixedly provided at the bottom of the first diagonal brace 12-1, and both ends of the support shaft 16 are located in the bottom slide groove 14 and move forward and backward along the bottom slide groove 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 top of the second diagonal brace 12-2 and the first diagonal brace 12-1 rise, thereby realizing the rise of the top lifting frame 11.

[0054] The invention provides an openable protective cover, on which a through hole matched with the positioning groove is formed, which can accurately irradiate the target culture dish with irradiation light and effectively protect other culture dishes from unnecessary irradiation, thereby ensuring the scientificity and rigor of the experiment.

[0055] Multiple positioning grooves 5 are arranged equidistantly along the length direction of the slide 4; the design of multiple culture dish positioning grooves on the slide of the present invention and the precise control of the motor can ensure that each culture dish can be accurately moved to the irradiation position, thereby improving the accuracy and repeatability of the experiment.

[0056] A groove 20 is arranged on the base 2 along its length direction, and the slider 3 is built into the groove 20, so that the slider 3 and the slide table 4 can move smoothly and safely.

[0057] The length of the slider 3 is consistent with that of the slide 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 .
