Description

Technical Field

[0001] The utility model relates to the technical field of flat culture dishes, and more specifically, to a precise positioning and cover buckling mechanism for a flat culture dish. Background Art

[0002] A petri dish is a flat, transparent container, usually made of glass or plastic, commonly used in laboratories for biological and microbiological experiments. It has a flat bottom and a lid and is used to culture and observe the growth of microorganisms, cells, or other biological materials. The inside of a petri dish is usually coated with a nutrient substance, such as agar, for the growth of microorganisms.

[0003] After searching, the existing patent (Announcement No.: CN202320682492.1) discloses a cover-closing mechanism for producing culture dishes, including a chain plate conveyor; a mold device for placing the lower cover of the culture dish is installed on the chain plate of the chain plate conveyor, and the mold device includes a mold shell, and a slide rail is installed on the lower surface of the mold shell, and a limit baffle is installed on the outer side end of the slide rail. The cover-closing mechanism for producing culture dishes can realize the rapid buckling of the upper and lower covers of the culture dish, and at the same time, the upper and lower covers of the culture dish have high positioning accuracy during the buckling process, which can effectively improve the production efficiency of the culture dish; the lower cover of the culture dish can be positioned by placing the lower cover of the culture dish into the positioning groove on the upper surface of the mold shell, and the position of the lower cover of the culture dish can be fine-tuned by pushing the mold shell to move along the slide rail; multiple upper covers of the culture dishes to be spliced ​​are placed on the upper surface of the flexible support plate, and the upper covers of the culture dishes are driven downward by the belt conveyor. When the upper cover of the culture dish moves to the lower end, the four electrically controlled telescopic rods are synchronously extended to push out the L-shaped pressing plate.

[0004] However, during the processing of the above device, the culture dishes need to be arranged in the order of dish bottom and dish cover. Therefore, during the process of capping, the dish cover is grabbed and tilted at a certain angle to wait for the arrival of the dish bottom behind. When the outer edge of the dish bottom is about to touch the inner circle of the tilted dish cover, the dish cover is released and accompanied by a downward pressure action to buckle the dish cover on the dish to complete the capping action. This traditional method requires a lot of space; the timing of grabbing and releasing the dish cover is difficult to control, and it takes more than 2 hours to change the specifications. It also requires very high mechanical literacy of the operator (increasing labor costs); if the conveying speed is fast, the dish bottom will partially run out of the dish cover range at the moment of releasing the cover, resulting in inaccurate capping, broken cover, and product damage.
