Patent number: 10676012Abstract: An unpowered stop mechanism includes a mounting seat, a driving member, and a stop assembly. The stop assembly is located on the mounting seat and oppositely positioned to the driving member. The stop assembly includes a guide member, a stop member, and a hinge arm. The stop member is received within a guide slot defined in the guide member. The hinge arm is pivotably coupled to the guide member. The hinge arm protrudes from the guide member and is oppositely positioned to the driving member. The driving member drives the hinge arm to drive the stop member to retract within the guide slot. Then the driving member is moved to be spaced from the hinge arm, the stop member is driven by a resilient member received within the guide slot to protrude out of the guide slot.Type: GrantFiled: July 25, 2018Date of Patent: June 9, 2020Assignees: Fu Tai Hua Industry (Shenzhen) Co., Ltd., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Yan-Fang Yan, Jing-Wei Liu, Shun-Ming Wang, Zhen-Ke Zhang, Shi-Li Zhang, Zheng-Hu Jiang, Ri-Qing Chen, Xue-Feng Che, Xi-Hang Li, Eddy Liu

Patent number: 10225968Abstract: A fixture to enable correct positioning of components in surface mount technology (SMT) field includes a tray, a positioning mechanism, at least one first upper magnet, at least one second upper magnet, and at least one lower magnet. The tray has at least one positioning hole. The positioning mechanism includes a base member, at least one sliding assembly, and at least one positioning post. The sliding assembly is slidably mounted to the base member. The positioning post is mounted to the base member, and disposed in the positioning hole of the tray. The first upper magnet and the second upper magnet are attached to the tray. The lower magnet is attached to the sliding assembly. The tray and the positioning mechanism are repulsive when the lower magnet aligns with the first upper magnet but are attracted when the lower magnet aligns with the second upper magnet.Type: GrantFiled: May 9, 2018Date of Patent: March 5, 2019Assignees: Fu Tai Hua Industry (Shenzhen) Co., Ltd., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Eddy Liu, Xi-Hang Li, Xue-Feng Che, Ri-Qing Chen, Xing Xia
