Automated library preparation system

An automated library preparation system, comprising:

• a plurality of consumable item storage devices configured for storing a consumable item;
• at least two dispatching transfer devices movable in a first direction;
• and
• a plurality of biochemical reaction devices which are spaced apart in the first direction, each of the plurality of biochemical reaction devices being configured to perform one subprocess of sample preparation for gene sequencing, wherein each of the at least two dispatching transfer devices is configured to grab a consumable item stored in a corresponding consumable item storage device of the plurality of consumable item storage devices, each of the at least two dispatching transfer devices is further configured to transfer a consumable item to the plurality of biochemical reaction devices as the at least two dispatching transfer devices sliding in the first direction;
• each of the plurality of consumable item storage devices comprises a storage rack for storing a consumable item, a discharging support plate, a discharging manipulator, a horizontal guide rail, and a vertical guide rail, the discharging manipulator is slidably disposed on the horizontal guide rail and the vertical guide rail and is configured to clamp a storage item in the storage rack and transfer the clamped consumable item to the discharging support plate;
• each of the at least two dispatching transfer devices comprises a dispatching transfer assembly, the dispatching transfer assembly comprises a dispatching manipulator, a consumable item buffer plate arranged at a first end of the dispatching manipulator, and a clamping jaw arranged at a second end of dispatching manipulator, and the dispatching manipulator is configured to drive the clamping jaw to clamp a consumable item on the discharging support plate and transfer clamped consumable item to the consumable buffer plate.
