US Patent 12006165 Suction gripping device, transfer system, and transfer method

According to one embodiment, a suction gripping device includes a pad mechanism mounted to a base. The pad mechanism includes a sliding part and a first guide. The sliding part includes a suction pad and a pipe and is slidable in a first direction with respect to the base. The suction pad attaches to a workpiece and is connected to the pipe at one end of the pipe. The first guide guides a sliding direction of the pipe to be in the first direction. The first guide is fixed with respect to the base. An attachment surface of the suction pad contacts a first surface of a workpiece and is tiltable due to a weight of the sliding part when gripping the workpiece. The first surface crosses a sliding direction of the sliding part.
