[0065] The working process of the laboratory consumables cabinet is introduced below.

[0066] The operator transmits the instruction information of the required experimental consumables 4 to the control unit through the touch screen 17, or the control unit can also directly issue the instruction information of taking a certain experimental consumable 4. The control unit controls the manipulator 3 to move accurately up, down, left, and right to the picking position, which corresponds to the consumables storage position 232 where the target experimental consumables 4 are located along the front-to-back direction. The control unit controls the manipulator 3 to move forward and fork the required experimental consumables 4. The control unit controls the manipulator 3 to move backward. The manipulator 3 moves up, down, left, and right to move the required experimental consumables 4 accurately to the storage position, which corresponds to the cabinet position 231 along the front-to-back direction. The manipulator 3 moves forward accurately to place the experimental consumables 4 on the cabinet position 231. The picking robot drives away the experimental consumables 4 from the cabinet outlet 16.

[0067] When the weight or quantity of the laboratory consumables 4 in the laboratory consumables cabinet is insufficient, the left cabinet door 111 and the right cabinet door 112 are opened, and the laboratory consumables 4 can be placed on the consumables storage position 232 of the consumables storage plate 23 manually or mechanically.
