Transfer device and transfer method

A transfer device, comprising:

• a frame;
• a module transfer arm, arranged above the frame and with a number of at least one set;
• a pre-inspection station, arranged on the frame at an initial placement position in a conveying direction of the module transfer arm, and configured to place thereon a target object to be inspected;
• a post-inspection station, arranged on the frame at a finish-placement position in the conveying direction of the module transfer arm, and configured to place thereon the target object after being inspected;
• inspection stations, respectively arranged on the frame and between the pre-inspection station and the post-inspection station, and configured to place thereon and inspect the target object;
• a feed mechanism, in connection with the module transfer arm, and configured to transfer the target object from the pre-inspection station to one of the inspection stations and to lift the target object to avoid inspectors through automatic operation or under the drive of the module transfer arm;
• and
• a discharge mechanism, in connection with the module transfer arm, and configured to transfer the target object from one of the inspection stations to the post-inspection station and to lift the target object to avoid the inspectors through automatic operation or under the drive of the module transfer arm;
• a number of the inspection stations is at least eight, the inspection stations are evenly distributed at both sides of the module transfer arm, and each of the inspection stations is corresponding to one inspector;
• and
• the frame is provided with an electric cabinet configured to control the module transfer arm and movements of robotic arms;
• wherein the discharge mechanism is further configured to:
• pick up or turn the target object after the inspection by the discharge mechanism such that a height of the target object is greater than a height of an inspector, and transfer the target object to the post-inspection station.

A transfer method, comprising:

• placing a target object to a pre-inspection station, picking up the target object to avoid inspectors and placing the target object on an inspection station;
• inspecting the target object placed on the inspection station;
• and
• picking up the target object after the inspection to avoid the inspectors and placing the target object to a post-inspection station;
• wherein the step of placing the target object to a post-inspection station further comprises:
• picking up or turning the target object after the inspection by a discharge mechanism such that a height of the target object is greater than a height of an inspector, and transferring the target object to the post-inspection station.
