When the storage compartment 3 is placed into the storage box 2, the second connector is plugged into the first connector, thereby realizing the connection between the reading and writing device and the password device 31. That is, information of the user, information of the items stored in the storage compartment 3, etc. can be stored in the password device 31, so that it is convenient to take the items in the storage compartment 3 according to the information of the user.

[0043] Specifically, the self-service item pickup device 10 further includes an extraction device 4. The extraction device 4 is disposed on one side of the body 1 for extracting the storage compartment 3 from the storage cavity 21 to facilitate the user to extract the items in the storage compartment 3.

[0044] In one embodiment, please refer to Figure 1 and Figure 3 , the extraction device 4 includes a mounting frame 41, a first extraction assembly 42, and a first lifting assembly 43. The mounting frame 41 is mounted on one side of the body 1. The first lifting assembly 43 is mounted on the mounting frame 41 and is drivingly connected to the first extraction assembly 42 to drive the first extraction assembly 42 to move on the mounting frame 41 for extracting the storage compartment 3. That is, under the drive of the first lifting assembly 43, the first extraction assembly 42 can extract different storage compartments 3 in different storage boxes 2, which is practical and convenient.

[0045] In one embodiment, please refer to Figure 2 and Figure 3 , the first lifting assembly 43 includes a first lifting driving member 431 and a lifting plate 432. The first lifting driving member 431 is mounted on the body and is drivingly connected to the lifting plate 432. The first extraction assembly 42 is mounted on the lifting plate 432. That is, under the drive of the first lifting driving member 431, the first extraction assembly 42 can be lifted relative to the mounting frame 41, so as to extract the storage compartments 3 at different positions.

[0046] In this embodiment, the first lifting assembly 43 includes a first lifting driving member 431 and a lifting plate 432. It should be noted that there are two lifting plates 432. The first lifting driving member 431 includes a lifting driving motor 4311, three lifting driving belts 4312, multiple lifting belt pulleys 4313, and a transmission rod 4314. The lifting driving motor 4311 is drivingly connected to one of the lifting belt pulleys 4313. The transmission rod is provided with multiple lifting belt pulleys 4313 arranged at intervals, and the remaining lifting belt pulleys 4313 are arranged at intervals on the mounting frame 41. One side of one of the lifting driving belts 4312 is wound around the lifting belt pulley 4313 on the lifting driving motor 4311, and the other side of the lifting driving belt is wound around one of the lifting belt pulleys 4313 on the transmission guide rod.

That is, after the first extraction member 422 arrives at the target position under the drive of the first lifting assembly 43 and the second driving member 424, it is then driven by the first driving member 423 to approach the storage compartment 3, and finally the storage compartment 3 is taken out of the storage box 2. Finally, the taken-out storage compartment 3 is driven by the first lifting assembly 43 and the second driving member 424 to go to the corresponding position for the next process.

[0050] In an embodiment, please refer to Figure 4 and Figure 5 , the first driving member 423 includes two relatively arranged first guide rail racks 4231, two first guide rails 4232, two first sliders 4233, and a first driving group 4234.

It should be noted that the first driving group 4234 is a common belt drive, and of course it can also be other driving methods, which are not limited in this application.

[0052] In one embodiment, please refer to Figure 5 , the first extraction member 422 includes a body 4221 and an extraction end 4222. The second driving member 424 is drivingly connected to the body 4221. The extraction end 4222 is disposed on one side of the body 4221. The extraction end 4222 is bent away from the second driving member 424 on the side away from the body 4221;

[0053] On one side of each storage compartment 3 close to the opening, there is an extraction groove 32 that cooperates with and is connected to the extraction end 4222. The extraction groove 32 is U-shaped. Through the mutual cooperation between the extraction end 4222 and the extraction groove 32, the storage compartment 3 can be quickly and accurately taken out of the storage box 2.

It should be noted that the extracted storage grid 3 is placed on the two first placement racks 426. When the two first placement racks 426 move up and down relative to the extraction rack 421 under the drive of the third driving component, the storage grid 3 is also driven to move up and down. During the rising process, the separation between the storage grid 3 and the first extraction member 422 is realized. It should be noted that the third driving member 425 is a common belt drive, and of course, other driving methods can also be used. This application does not make a limitation here.

[0064] In one embodiment, please refer to Figure 6 and Figure 7 , the second extraction component 44 further includes a switch board 447 and a seventh driving member 448. The seventh driving member 448 is arranged on the connecting frame 442 and is drivingly connected to the switch board 447 to drive the switch board 447 to movably cover a part of the connecting frame 442 and be located above the second placement frame 446. When the switch board 447 moves to a certain position, the user can reach into the connecting frame 442 to take out the items in the storage compartment 3.

[0065] In this embodiment, the second extraction component 44 further includes a switch board 447 and a seventh driving member 448. The seventh driving member 448 is disposed on the connecting frame 442 and is drivingly connected to the switch board 447, so as to be able to drive the switch board 447 to movably cover a part of the connecting frame 442. Thus, when it is necessary to take out the items in the storage compartment 3, the seventh driving member 448 drives the switch board 447 to move towards the mounting frame 41, so as to expose a part of the connecting frame 442, facilitating the user to take out the items. Similarly, under the drive of the seventh driving member 448, the switch board 447 moves away from the mounting frame 41. In this way, the safety of the entire device is improved. It should be noted that the seventh driving member 448 is a common belt drive. Of course, it can also be other driving methods, which are not limited in this application.

[0066] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the description and drawings of the present invention under the technical concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
