Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveying, in particular to a culture dish conveying device. Background Art
[0002] The petri dish is a laboratory dish commonly used in laboratories. The petri dish structure consists of a flat disc-shaped bottom plate and a lid, usually made of transparent material to facilitate observation of the contents. The functions of the petri dish mainly include: providing a suitable growth environment and isolating external pollution; the transparent bottom plate and lid facilitate observation and operation; it is suitable for cell experiments, biochemical experiments, microbial culture, etc.
[0003] Culture dishes with stable ingredients can be stored in a cabinet at room temperature. When in use, the experimenter takes several culture dishes from the cabinet and transfers them to the laboratory bench. The problem is that only several culture dishes can be taken from the cabinet at a time, which is inefficient. If a stack of culture dishes is taken at a time, there is a risk of the culture dishes tipping over, which is generally not done. After all the required culture dishes are transferred to the laboratory bench, the experimenter needs to check the contents of each culture dish in turn to see if they are damaged or have foreign matter. Only culture dishes that meet the requirements can be used for culture experiments. When checking the culture dishes, all culture dishes need to be laid flat on the laboratory bench. Even if they are not completely laid flat, the culture dishes will take up more area of the laboratory bench, affecting the space for experimental operations. Utility Model Content

[0017] like Figure 1 As shown, this embodiment provides a culture dish conveying device, which is arranged on one side of the experimental table 1, and the device includes a support frame 2, a delivery mechanism 4, and a limiting mechanism 3.
[0018] Specifically, the support frame 2 includes a platform 21 and four legs 22 . The four legs 22 are arranged at the bottom of the platform 21 . The platform 21 is inclined downward toward the experimental table 1 . Side panels 23 are arranged on both sides of the platform 21 .
[0019] Specifically, the delivery mechanism 4 is arranged at a higher end of the platform 21, and is used to lay a stack of culture dishes on the platform 21 in sequence. In the accompanying drawing, only three culture dishes are shown on the platform 21. In actual application, the length of the platform 21 can be extended as needed to lay more culture dishes.
[0020] There are many ways to implement the delivery mechanism 4. In this embodiment, Figure 1 , Figure 2 As shown, the delivery mechanism 4 includes a telescopic component 41, a push plate 42 and four positioning rods 43. The positioning rods 43 are vertically arranged on the top of the bottom plate, and the bottom plate is connected to the inner wall of the side plate 23. The four positioning rods 43 are distributed in a rectangular array. The area between the four positioning rods 43 is used to place a stack of culture dishes. The height between the bottom surface of the bottom plate and the platform 21 is greater than the height of a culture dish and less than the height of two culture dishes. The telescopic component 41 is connected to the push plate 42. The power source of the telescopic component 41 can be driven by a cylinder, an oil cylinder or a hydraulic cylinder. When the telescopic component 41 is extended, the push plate 42 can push the culture dish at the bottom of the stack of culture dishes toward the laboratory table 1.
[0021] Specifically, Figure 1 , Figure 3 As shown, the limiting mechanism 3 is arranged on the support plate 24, and the limiting mechanism 3 is located between the delivery mechanism 4 and the laboratory table 1. The limiting mechanism 3 is used to intercept and lock one of the culture dishes. After the limiting mechanism 3 is unlocked, the culture dish slides toward the laboratory table 1, and the limiting mechanism 3 is used to lock the next culture dish.
[0022] There are many ways to implement the limiting mechanism 3. In this embodiment, Figure 1 , Figure 3As shown, it includes a motor 31, a moving wheel 32, a spring 33, a locking rod 34, a disc 35 and a cross 36. The motor 31 is arranged at the bottom of the support plate 24, and the support plate 24 is connected to the support frame 2. The output shaft of the top of the motor 31 passes through the support plate 24 and is connected to the moving wheel 32. A protrusion 321 is provided on the outer wall of the moving wheel 32. The disc 35 is rotatably arranged on the support plate 24. Four notches 351 are evenly arranged on the outer circumference of the disc 35. The notch 351 is V-shaped. The plane where one of the inner walls of the V-shaped notch 351 passes through the center of the disc 35. The cross 36 is fixedly arranged on the top of the disc 35. One of the side plates 23 is provided with an avoidance groove 231. Two of the cross 36 supports After the section passes through the avoidance groove 231, a culture dish is locked. The size of the avoidance groove 231 cannot hinder the rotation of the cross 36. A column 25 is provided on the top of the support plate 24. Both ends of the spring 33 are respectively connected to the column 25 and the locking rod 34. The spring 33 is located between the disc 35 and the moving wheel 32. One end of the locking rod 34 is rotatably connected to the support plate 24, and the other end of the locking rod 34 is provided with a hook. Under the action of the spring 33, the hook at the other end of the locking rod 34 is used to lock one of the notches 351. An arc block 341 is provided on the side of the middle section of the locking rod 34 facing the moving wheel 32. When the protrusion 321 rotates, it is used to squeeze the arc block 341 to make the locking rod 34 disengage from the notch 351.
[0023] The principle is as follows: Figure 3 From the perspective, the motor 31 drives the moving wheel 32 to rotate clockwise, and the protrusion 321 squeezes the arc block 341, causing the locking rod 34 to disengage from the notch 351. Because the platform 21 is tilted, the culture dish on the platform 21 tends to slide down. When the disc 35 is locked, the cross 36 will rotate under the gravity of the culture dish. When the cross 36 rotates 90°, the cross 36 releases a culture dish and then locks the next culture dish. During the 90° rotation of the cross 36, the disc 35 also rotates synchronously with the cross 36. The hook of the locking rod 34 is close to the outer wall of the disc 35. When the hook moves to the next notch 351, the hook locks the disc 35 again under the action of the spring 33.
[0024] The culture dish released by the cross 36 will continue to slide down. In order to ensure that the culture dish can finally slide smoothly to the side of the experimental table 1, this embodiment is provided with an extension plate 26 at one end of the platform 21 facing the experimental table 1, and a buffer zone 261 is provided on the top surface of the extension plate 26. The buffer zone 261 can reduce the sliding speed of the culture dish, so that the culture dish finally stops in the buffer zone 261, which is convenient for the experimenter to take the culture dish.
[0025] The method of use is as follows: assuming that 10 culture dishes can be laid out on the platform 21, the 10 culture dishes are pushed out from a stack of culture dishes using the push plate 42, and the first culture dish is locked using the cross 36. Then the experimenter can check whether the quality of the 10 culture dishes is qualified next to the platform 21. If there are unqualified culture dishes, they can be picked out; when the experimenter stands at the experimental table 1 to conduct an experiment, the limiting mechanism 3 releases the first culture dish, and the first culture dish slides to the buffer zone 261. After the first culture dish is inoculated, the limiting mechanism 3 releases the second culture dish, and so on; when the culture dishes laid out on the platform 21 are all inoculated, the next batch of 10 culture dishes are laid on the platform 1 for standby use.
[0026] In summary, this solution has multiple advantages: by utilizing the cooperation of the platform 21, the delivery mechanism 4, and the limiting mechanism 3, multiple culture dishes can be automatically spread out on the platform 21 so that the experimenter can perform a quality inspection on the culture dishes; when the culture dishes are undergoing a quality inspection, the area of the laboratory table 1 is not occupied; when inoculating, the limiting mechanism 3 can automatically release a culture dish, which can automatically slide to the side of the laboratory table 1, and the experimenter does not need to go to the cabinet to take the culture dish.
[0027] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
