During this process, the observation object placed on the board gradually approaches the objective lens of the observer. At this time, the staff can observe the items in the culture medium through the observer. If the staff needs to take out the observation object according to the observation results, the first lifting door panel can be opened and the sample can be taken out. If it is not necessary to take it out, the first lifting door panel can be kept open to reduce the air exchange between the inside and the outside of the device.

[0028] In the present invention, the linear rail 10 is fixedly installed on the bottom outer wall of the top plate 5, the linear motor 9 is slidably connected to the bottom of the linear rail 10, the first electric telescopic rod 11 is fixedly installed on the bottom outer wall of the linear motor 9, an L-shaped connecting rod is provided at one end of the second electric telescopic rod 15, the rotating rod 16 is rotatably connected to the outer wall of the L-shaped rod through a bearing, the electric clamp 17 is installed on the outer wall of the rotating rod 16, and the rotating rod 16 is movably connected to the L-shaped rod, so that under the action of the deadweight of the electric clamp 17, the clamping clock of the electric clamp 17 can be kept vertically downward without being affected by the state of the robotic arm.

[0029] In the present invention, the robotic arm is composed of a first connecting arm 12, a rotating motor 13 and a second connecting arm 14. The first connecting arm 12 is fixedly installed on the bottom outer wall of the first electric telescopic rod 11, and the second connecting arm 14 is movably connected to one side outer wall of the first connecting arm 12. The rotating motor 13 is installed on one side outer wall of the second connecting arm 14. The movement of the rotating motor 13 can drive the second connecting arm 14 to rotate with the output shaft of the rotating motor 13 as the center line, thereby realizing the right-angle rotation of the robotic arm.

[0030] In the present invention, the lifting mechanism is composed of a short rod 18, a support block 19, a slide rod 20, a driven gear 21, a driving gear 22, a connecting rod 23, a first support frame 24, a second support frame 25, a lifting motor 30, a placement plate 31 and a guide block 32.

[0031] In the present invention, the first support frame 24 is fixedly installed on the bottom of the inner wall of the observation chamber 27, the lifting motor 30 is fixedly installed on one side inner wall of the observation chamber 27, the driving gear 22 is arranged at both ends of the connecting rod 23, and the two ends of the driving gear 22 are in rotational contact with the first support frame 24 through bearings. The output shaft of the lifting motor 30 is transmission-connected to the driving gear 22 through a coupling, and the driven gear 21 is meshed with the driving gear 22. The two ends of the short rod 18 are rotationally connected to the second support frame 25 through bearings, and the driven gears 21 are fixedly connected to the outer wall of the short rod 18.

[0032] In the present invention, there are two support blocks 19, which are arranged between the two second support frames 25. The guide blocks 32 are fixedly connected to the outer walls of the second support frames 25. The slide rod 20 is in sliding contact with the guide blocks 32. The driving gear 22 and the short rod 18 are both located in eccentric positions. A placement plate 31 is fixedly installed on the top outer wall of the support block 19.

[0033] In the present invention, a limiting block 28 is fixedly installed on the top of the slide rod 20 .

[0035] When in use, the staff controls the linear motor 9 to move along the linear rail 10 through the set operation control panel 6, and then controls the first electric telescopic rod 11 to extend to a suitable position, and the rotating motor 13 is actuated to make the second connecting arm 14 in a vertical state, so that the electric clamp 17 falls above the culture product that needs to be taken. After the electric clamp 17 clamps the observation product, the rotating motor 13 is actuated again to make the second connecting arm 14 in a horizontal position, and the first electric telescopic rod 11 is appropriately retracted.

When the short rod 18 runs to a suitable position, the lifting motor 30 stops rotating. At this time, the third lifting door plate 26 descends, and the second electric telescopic rod 15 is appropriately When extended, the electric clamp 17 opens to place the observation object on the placement plate 31, and then the second electric telescopic rod 15 retracts, the third lifting door plate 26 rises, and the lifting motor 30 rotates again, so that the short rod 18 moves to the highest position. During this process, the observation object on the placement plate 31 gradually approaches the objective lens of the observer. At this time, the staff can observe the items in the culture medium through the observer. If the staff needs to take out the observation object according to the observation results, the first lifting door plate 4 can be opened to take out the sample; if it does not need to be taken out, the first lifting door plate 4 can be kept closed to reduce the air exchange between the inside and outside of the device; since an observation window is installed on the placement rack 3, the observation window is made of transparent material, and there is a sealed contact between the observation window and the placement rack 3, the staff can roughly understand the appearance of the sample through the observation window, thereby solving the problem that the observation range of the eyepiece is small and the overall appearance of the sample cannot be observed.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
