Abstract: A centrifugal moisture removal device includes a rotating mechanism and a fixing mechanism. The rotating mechanism includes a rotating bracket and a rotary driving member. The rotating bracket includes two sleeving portions. The fixing mechanism includes two positioning members, two clamping members, and two line driving members. Each clamping member includes a moving staff, an elastic member, and a sensing member. A first end portion of the moving staff passes through a sleeving portion and is mounted on a positioning member. The elastic member is sleeved on the moving staff. A first end portion of the elastic member resists the sleeving portion. A second end portion of the elastic member resists a second end portion of the moving staff. Each line driving member is set above the second end portion of a moving staff. The sensing member senses when the workpiece arrives at the positioning member.

Abstract: A screw device, for screws to a workpiece, comprises a platform, a feeding mechanism, a transferring mechanism, and a mechanism. The transferring mechanism is mounted on the platform and communicating with the feeding mechanism. The locking mechanism comprises a mounting plate, a first driving assembly, a second driving assembly, and a pneumatic sucker. The mounting plate is fixed on the platform. The first driving assembly is mounted on the mounting plate. The second driving assembly is fixedly connected to the first driving assembly. The pneumatic sucker is mounted on an end of the second driving assembly adjacent to the platform, and is located near an end of the first transferring member, the first driving assembly driving the second driving assembly and the pneumatic sucker to move along an axis of the pneumatic sucker. The second driving assembly drives the pneumatic sucker to rotate.
