Multiple rack side uprights 122 may be provided, and the multiple rack side uprights 122 are respectively connected to different sides of the rack base plate 121 and rack top plate 123. The rack base plate 121, rack side uprights 122, and rack top plate 123 enclose a hopper and an inlet / outlet for the material handling mechanism 210 to enter and exit the hopper.

[0047] In one specific embodiment, the bottom plate 121, top plate 123, and side plates 122 of the rack are all rectangular plates, and there are two side plates 122, which are respectively located on the left and right sides of the rack mechanism. The front side of the rack mechanism forms an inlet and outlet for the culture dish 20 and the material handling mechanism 210 to enter and exit.

The two sensor mounting plates 1311 are respectively equipped with an origin sensor 138 and a lifting position sensor 139. A sensing plate 1310 is installed on the lifting side mounting plate 135. When the origin sensor 138 senses the sensing plate 1310, it indicates that the lifting drive component 132 has returned to the origin. When the lifting position sensor 139 senses the sensing plate 1310, it indicates that the lifting drive component 132 drives the lifting positioning component 131 to lift into place, thus realizing the insertion of the lifting positioning component 131 into the second positioning hole 1212.

The side slider 228 is slidably connected to the side rail 227.

[0077] The material handling mechanism 210 includes a material handling plate connected to the output end of the Y-axis module 241. The material handling plate can hold the culture dish 20 from below and move the culture dish 20 into or out of the material rack assembly 120 under the drive of the Y-axis module 241.

[0078] Optionally, the feeding mechanism 210 is provided with a culture dish positioning component 211, which is used to position the culture dish 20. Optionally, the culture dish positioning component 211 is provided on the feeding plate. Optionally, multiple culture dish positioning components 211 are provided, and multiple culture dish positioning components 211 form a limiting groove for limiting the culture dish 20.

[0079] To detect whether there is a culture dish 20 on the feeding plate, the feeding mechanism 210 is provided with a second detection mechanism 212, which is used to detect the presence or absence of the culture dish 2. Optionally, the second detection mechanism 212 is a presence or absence sensor provided on the feeding plate; more preferably, the second detection mechanism 212 is an infrared sensor.

[0080] Optionally, the material handling module 200 also includes a barcode scanner 250, which is mounted on the base of the material handling module 200 via a barcode scanning mounting plate. The barcode scanner 250 is used to scan the barcode on the petri dish 20 located on the material handling mechanism 210. The barcode carries information about the material inside the petri dish 20.

[0081] The working process of the material handling module 200 is as follows: First, the lifting drive mechanism 220, the horizontal movement drive mechanism 230 and the telescopic drive mechanism 240 work together to control the material handling plate to handle the culture dishes 20 in the hopper. During this process, the second detection mechanism 212 on the material handling plate detects the presence or absence of the culture dishes 20 and prompts manual confirmation in a timely manner. The barcode scanner 250 located below the material handling plate scans the barcode on the culture dish 20 when it passes by and prompts abnormal situations through the software.

[0082] In this embodiment, the automated stack mechanism 10 also includes a control mechanism, which can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control each of the above-mentioned electronic control components to perform its function.

[0083] The loading process of the automated stacking mechanism 10 provided by this utility model is as follows: First, the drawer assembly 110 is manually pulled out, and six rack assemblies 120 containing culture dishes 20 are placed into the six drawer assemblies 110 one by one; then, the drawer assembly 110 is manually pushed all the way down. After the software process is started, the lifting positioning part 131 of the lifting assembly 130 moves up to position the rack assembly 120, and the magnetic part 1312 is attracted to the magnetic part 127 located at the bottom of the rack assembly 120. Since the rack assembly 120 is positioned on the drawer assembly 110, the drawer assembly 110... Together with the lifting component 130, the material rack component 120 is positioned. Then, the material pick-up plate of the material pick-up module 200 extends into the material rack component 120. The second detection mechanism 212 detects whether there is a culture dish 20 on the material pick-up plate. If no culture dish 20 is detected, a software pop-up window will prompt the user. If no prompt is received, the material pick-up plate removes the designated culture dish 20. After removal, the barcode scanner 250 located at the bottom of the material pick-up plate reads the barcode of the culture dish 20 as it passes over it and provides feedback on whether there is an anomaly. Simultaneously, it remains in a waiting position for subsequent process operations. Finally, this process is repeated to complete all material loading. It should be noted that the unloading process is the reverse, and will not be elaborated here.

[0084] The automated stacking mechanism 10 provided by this utility model has the following advantages:

[0085] 1. It can replace manual labor to achieve fully automatic functions such as feeding, counting, scanning, unloading and storage of culture dishes 20. It can be integrated into an automated sorting platform to complete the automatic loading and unloading of culture dishes 20 throughout the entire process, which greatly improves the degree of automation.

[0086] 2. It solves the problem of low efficiency in manual operation, saves 90% of labor, and greatly reduces labor costs.

[0087] This utility model also discloses a sample processing device for dispensing and sorting culture dishes, which includes the aforementioned automated stacking mechanism. By using the automated stacking mechanism, automatic loading and unloading of culture dishes 20 is achieved, improving the loading and unloading efficiency of culture dishes 20, saving labor, and reducing costs. It should be noted that the sample processing device for dispensing and sorting culture dishes also includes a processing mechanism for processing the culture dishes 20. This processing mechanism can employ existing technology and will not be described in detail here.

[0088] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
