Claim Text:
1. A panel unpacking method, comprising the following steps: (1) providing a panel unpacking device, wherein the panel unpacking device comprises a pickup device and a conveyance device, the pickup device comprising a manipulator and suction cups mounted to ends of the manipulator, the conveyance device comprising a main body, a mounting board mounted on the main body, pins mounted on the mounting board, and cushioning devices installed on the pins, the pins each comprising a pin stem and a contact section connected to an end of the pin stem, the cushioning devices each having an end positioned against the contact section of the respective pin and an opposite end positioned against the mounting board, the mounting board forming a plurality of positioning holes corresponding to the pins, ends of the pin stems of the pins that are distant from the contact sections being respectively received in the positioning holes and movable in the positioning holes in an axial direction of the positioning holes; (2) moving the manipulator to a location exactly above a panel to be unpacked and moving the manipulator downward to approach the panel until the suction cups at the ends of the manipulator get into contact with the panel; (3) the suction cups sucking and holding the panel and the manipulator making a movement to lift up the panel; (4) the manipulator carrying and moving the panel to a location exactly above the conveyance device, the manipulator moving downward to approach the pins of the conveyance device until the panel gets into contact with the contact sections of the pins, wherein the suction cups and the pins are on opposite sides of the panel and are vertically opposite to each other; and (5) the suction cups releasing the panel from a top side of the panel to allow the panel to apply a downward depressing force to the contact sections of the pins that is on the bottom side of the panel so as to cause the contact sections of the pins to move downward and compress the cushioning devices, whereby the cushioning devices undergo elastic deformation to cushion the downward depressing force, making the panel stably positioned on the contact sections of the pins of the conveyance device.
