DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0026] Referring to Figures 1 - 4 As shown, an AGV multi-functional transfer vehicle includes a vehicle body 1. A control module 6 is provided at the front end of the vehicle body 1. The control module 6 includes a battery module and various sensors, which are used for automatic walking, route selection, obstacle avoidance, etc. It also includes:

[0027] A storage bin 4 is provided on the vehicle body 1 for placing sample boxes.

[0028] A freezer 2 is provided at the bottom of the storage bin 4 and can be maintained at an appropriate temperature as needed. It is used to provide cold air to the storage bin 4. A circulating cold air channel can be set for the storage bin 4 to more effectively maintain the low-temperature environment of the storage bin 4.

[0029] A defrosting mechanism 3 is provided on the storage bin 4, mainly for the sample box. During the transfer process of the sample box, frost is likely to form on its surface. At this time, the surface of the sample box can be defrosted by the defrosting mechanism 3.

[0030] A cover plate 5 is rotatably arranged on the storage bin 4 through a drive shaft 51 and can be used as a sealing cover to seal the storage bin 4. When taking out the sample box, the cover plate 5 can also be turned up 180° to be flush with the top of the storage bin 4. Then, after the sample box is defrosted by the defrosting mechanism 3, it can be pushed onto the cover plate 5 by a robotic arm 7 for subsequent operations, such as directly transferring the sample box to a freezer for storage, or opening the sample box to take out the cryotubes inside.

[0031] In one embodiment, the defrosting mechanism 3 includes a bottom scraper 31 located inside the storage bin 4. The bottom of the bottom scraper 31 is connected to the bottom of the storage bin 4 through a first hydraulic rod 32. A side scraper 33 is provided at the upper end of the bottom scraper 31, and the side scraper 33 is also located inside the storage bin 4.

[0032] Generally, the sample box is in an uncovered manner. Therefore, it is only necessary to defrost the four walls and the bottom of the sample box. At the same time, the bottom scraper 31 can be divided into two parts. The first part is the first scraper fixed at the bottom, and its size is adapted to the smallest volume of the sample box. Then, a second scraper with a certain elasticity can be provided at the outer periphery of the first scraper. When the size of the sample box is small, when the bottom scraper 31 passes through the side scraper 31, the second scraper will bend to a certain extent, so as to facilitate passing through the side scraper 31.

[0033] At the same time, the scraper structure can also be correspondingly set into other structures such as brushes that are convenient for cleaning.

[0034] At the beginning, when placing the sample box, the cover plate 5 is opened so that the cover plate 5 is flush with the top of the storage bin 4. The sample box is first placed on the bottom scraper 31 from the top. After being transported to the destination, the sample box can be pushed upward by the first hydraulic rod 32. When it rises, it will also pass through the side scraper 33. If the overall size of the bottom scraper 31 is large, when passing through the side scraper 33, the side of the bottom scraper 31 will bend downward. First, the side scraper 33 is used to defrost the four walls of the sample box. Then, the sample box can be pushed by the robotic arm 7. The sample box slides from the bottom scraper 31 to the cover plate 5, and during its movement, it will be scraped by the bottom scraper 31 for defrosting.

[0035] In one embodiment, the side scraper 33 includes two movable scrapers 331 located inside the support platform 30. A second hydraulic rod 332 is provided outside the support platform 30. The movable end of the second hydraulic rod 332 is connected to the movable scraper 331. Two telescopic scrapers 333 are provided between the two movable scrapers 331, and the telescopic scrapers 333 are slidably connected to the movable scrapers 331.

[0036] The movable scraper 331 can move inward under the push of the second hydraulic rod 332, and the telescopic scraper 333 can make adaptive telescopic movements. At the same time, the telescopic scraper 333 can also slide back and forth inside the movable scraper 331, so as to be adjusted according to the size of the sample box, so that the movable scraper 331 and the telescopic scraper 333 can closely adhere to the four sides of the sample box.

[0037] In one embodiment, the movable squeegee 331 includes a first clamping plate 3311. A first side squeegee 3312 is provided at the top of the first clamping plate 3311. The movable end of the second hydraulic rod 332 is connected to the first side squeegee 3312. The telescopic squeegee 333 is slidably connected to the first clamping plate 3311.

[0038] In one embodiment, the telescopic squeegee 333 includes a fixed sleeve 3331. Telescopic sliding plates 3332 are slidably provided at both ends of the fixed sleeve 3331. A bidirectional threaded rod 3313 is rotatably provided inside the first clamping plate 3311. Here, a motor for driving is provided at one end of the bidirectional threaded rod 3313 on one side. Then, the two bidirectional threaded rods 3313 can achieve synchronous rotation through a belt transmission structure. A limit slider sleeved on the bidirectional threaded rod 3313 is provided on one side of the telescopic sliding plate 3332. The bottom of both the fixed sleeve 3331 and the telescopic sliding plate 3332 is a second clamping plate 3333. The top of the second clamping plate 3333 is a second side squeegee 3334;

[0039] After the top of the sample box rises into the side squeegee 33, first, the two movable squeegees 331 move inward simultaneously, so that the first clamping plate 3311 clamps the top end of the side wall of the sample box. Then, by rotating the bidirectional threaded rod 3313, the two telescopic squeegees 333 can be driven to move closer inward, so that the second clamping plate 3333 also clamps the side wall of the sample box. Next, the bottom squeegee 31 continues to rise, and the sample box will slide along the first side squeegee 3312 and the second side squeegee 3334 to complete the defrosting of the side of the sample box.

[0040] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
