Liquid handling system

An automated liquid handling system comprising:

• a transfer robot unit;
• a fixing unit fixed to the transfer robot unit to move integrally with the transfer robot unit;
• and
• a handling module which has a mounting part to be detachably mounted on the fixing unit and is configured to be detachably installed on the fixing unit by the mounting part,
• wherein the fixing unit includes a body part, a fixing unit hook formed at an upper portion of one side of the body part, and a lower protrusion extending in a horizontal direction at a lower portion of or below the one side of the body part,
• the mounting part includes a body, a movable hook part formed at an upper portion of one side of the body, and a lower groove formed at the lower portion of or below the one side of the body to correspond to the lower protrusion, and
• hook coupling is performed by the movable hook part and the fixing unit hook at upper ends of the fixing unit and the mounting part, catching step coupling is performed at a lower portion in which the lower protrusion and the lower groove are formed, and thus the mounting part is fastened to the fixing unit,
• wherein the movable hook part includes a pushing part and a mounting part hook,
• the mounting part hook is formed to face the fixing unit hook, and when the mounting part hook is coupled to the fixing unit hook, the mounting part is fastened to the fixing unit,
• wherein the mounting part further includes a guide groove positioned at an upper portion of the body to guide vertical movement of the movable hook part, and the movable hook part is configured to receive an upward spring force by a spring and a pin at a lower end thereof, and
• when the pushing part is pushed, the hook coupling is released.
