[0026] Example 1:

[0027] This embodiment Figure 1 As shown, an unattended automatic weighing intelligent material cabinet includes a cabinet body 1 with a PLC controller, a plurality of storage cavities are arranged in the cabinet body 1, a storage door 2 is rotatably installed at the opening of the storage cavity, the storage door 2 is provided with a lock nose, an electronic lock 3 adapted to the lock nose is provided on the cabinet body 1, a weighing storage mechanism 4 is provided in the storage cavity, and the control end of the electronic lock 3 and the weighing unit signal output end of the weighing storage mechanism 4 are both electrically connected to the PLC controller.

[0028] The PLC controller can be used to open and close the storage door 2. When it is opened, the materials are placed in each storage cavity and the corresponding material information (including but not limited to type, purpose, specification, weight and quantity, etc.) is entered until the inventory work of all materials is completed and all storage doors 2 are closed. When the material picker needs to pick up the materials, the storage door 2 is opened according to the material pick list (which may have information recognized by the PLC controller, including but not limited to passwords, QR codes or biometric information, etc.), and the storage door 2 is closed after the materials are picked up. At this time, the information in the storage cavity is updated and the new material information is recorded, such as automatically recording and saving the operator, operation time, name, specification, quantity and other information of the stored and accessed materials.

[0029] It is worth noting that the sizes of the various spaces in the storage cavity are different to accommodate the storage of materials of different specifications.

[0030] Preferably, a transparent window 5 is provided on the storage door 2 .

[0031] The material situation in the storage cavity can be observed through the transparent window 5, which is used to quickly find or verify the recorded material information.

[0032] Preferably, a plurality of display screens 6 are provided on the cabinet 1 , and the display screens 6 are electrically connected to the weighing unit of the weighing storage mechanism 4 via a PLC controller.

[0033] The display screens 6 can each display information about the materials in their respective storage cavities for easy identification.

[0034] Preferably, a light source 7 electrically connected to the PLC controller is provided in the storage cavity, and the light source 7 is an LED lamp.

[0035] The light source of the LED lamp can illuminate the storage cavity, making it convenient to take and place materials.

[0036] Example 2:

[0037] Based on the above embodiments, this embodiment Figure 2 and Figure 3As shown, the weight-type storage mechanism 4 includes a weighing sensor 8, a bracket 9 and a tray 10. The weighing sensor 8 is installed on the inner bottom surface of the storage cavity, and the signal output end of the weighing sensor 8 is electrically connected to the PLC controller. The bracket 9 is installed on the weighing sensor 8, and the tray 10 is placed on the bracket 9 and is located in the storage cavity.

When placing special materials, the tray 10 can be replaced more conveniently. The weighing sensor 8 is used for weighing. During the storage and retrieval process, under the control of the PLC controller, the output signal of the weighing sensor 8 is read in real time and converted into total weight data. The total weight data minus the preset weight of the tray 10 is the total weight of the materials on the tray 10. The total weight of the materials is divided by the unit weight of the materials to obtain the current material quantity.

[0039] Preferably, the bracket 9 is a cross-shaped structure, and limit baffles 11 are provided on the three ends. The limit baffles 11 are respectively provided in a one-to-one correspondence with the inner side surfaces of the storage cavity.

[0040] The limiting baffle 11 prevents the tray 10 from shaking arbitrarily on the bracket 9 and restricts the tray 10 to only pulling and pulling movements on the bracket 9 .

[0041] Preferably, a hand grip groove 12 is provided at the front end of the tray 10 .

[0042] It is convenient to hold the hand groove 12 to pull out the tray 10.

[0043] Preferably, the cabinet 1 is provided with a biometric identification device electrically connected to the PLC controller.

[0044] Such as face and fingerprint recognition, etc., to facilitate the opening and closing of the storage door 2.
