Patent number: 11850734Abstract: A gripper device includes a base and two gripping assemblies, each including a gripping member, a stand, and an elastic member. The gripping member includes a gripping portion and a supporting portion. The stand is movably disposed to the base and includes a connecter and a supporter. The supporting portion is pivotally connected to the supporter at a position between the gripping portion and the connecter so that the gripping member is pivotable relative to the stand. Two opposite ends of the elastic member are respectively connected to the supporting portion and the connecter. When one of the gripping portions touches an object, the gripping member pivots relative to the corresponding stand. Therefore, gripping a target may not be interrupted by interference objects around the target.Type: GrantFiled: June 2, 2021Date of Patent: December 26, 2023Assignee: Hiwin Technologies Corp.Inventors: Ming-Shiou Liu, Chen-Ming Wong

Publication number: 20180304474Abstract: A gripper-mounting mechanism includes an outer shell, a motor unit, a first transmission unit, and a plurality of second transmission units. The outer shell includes spaced-apart first and second walls, and a receiving wall that extends from the second wall toward the first wall and that defines a receiving channel adapted to receive an end effector therein through an opening of the second wall. The first transmission unit includes a transmission gear unit driven by the motor unit. The second transmission units surround the receiving wall. Each of the second transmission units includes a grip member driven movably by the transmission gear unit. The grip members are movable relative to the outer shell toward or away from each other.Type: ApplicationFiled: April 20, 2017Publication date: October 25, 2018Inventor: CHEN-MING WONG

Patent number: 10099370Abstract: A driving method used in a driver device for driving an electric gripper is disclosed to include the step of providing a state signal that is generated according to the operation state of the electric gripper, the step of receiving an action instruction and detecting a feedback signal indicative of the action of the electric gripper when the state signal is an idle state, and the step of outputting the action instruction if the action of the electric gripper indicative of the action instruction is not in consistency with the action of the electric gripper indicative of the feedback signal. Thus, the driving method of the present invention needs not to provide a trigger signal for commanding the electric gripper to execute the action instruction.Type: GrantFiled: March 14, 2016Date of Patent: October 16, 2018Assignee: HIWIN TECHNOLOGIES CORP.Inventors: Chen-Ming Wong, Wei-Shao Chen
