Unloading system

An unloading system for unloading a first workpiece and a second workpiece hung on different sides of a rack from the rack, the unloading system comprising:

• a transferring mechanism comprising:
• a transferring assembly for transferring the rack;
• and
• a clamping assembly movably mounted on the transferring assembly for clamping or releasing the rack;
• a sliding rod arranged parallel to a transferring direction of the transferring assembly;
• a rotating assembly slidably mounted on the sliding rod and connected to the rack;
• at least one first robot arm arranged adjacent to the transferring assembly and equipped with a first sensor;
• at least one second robot arm arranged adjacent to the transferring assembly and equipped with a second sensor;
• at least one first unloading mechanism assembled to the at least one first robot arms;
• at least one second unloading mechanism assembled to the at least one second robot arm;
• a controller electrically connected to the transferring mechanism, the rotating assembly, the at least two robot arms, the first sensor, the second sensor, and the at least one first and second unloading mechanisms;
• wherein the first sensor of one first robot arm adjacent to the rack senses the rack and sends signal to the controller, the controller controls the one corresponding first robot arm to move following the rack, and simultaneously drive corresponding first unloading mechanism toward the rack to unload the first workpiece from the rack, the clamping assembly releases the rack, thereafter, the rotating assembly rotates the rack to enable the second workpiece to face one second robot arm, the clamping assembly clamps the rack, the one second robot arm moves following the rack and drives the corresponding second unloading mechanism to unload the second workpiece from the rack.
