    Abstract: A mounting apparatus and system and method for making the same are provided. The mounting apparatus allows an object to be mounted to a mounting surface via magnetic attractions between different planes of engagement. Through the movement of planes of magnets, an object that is brought in proximity to the mounting apparatus may engage one of the magnetic planes and then be moved further to engage the other magnetic plane, with the combined magnetic force being configured to support the particular object for which the mounting apparatus is designed. The engagement and/or disengagement of the object from the mounting apparatus can thus occur in stages, by degrees, and/or in a tiered manner.

  • Patent number: 9500208
    Abstract: A first component is coupled to a second component by one or more joints. Magnetic force between at least a first magnetic and second magnetic unit preloads the joint by placing the joint in compression. The first and second magnetic units may be respectively coupled to the first and second components. The magnetic force acts as a retentive force between coupled components and/or the joint and operates to resist one or more tensile and/or other opposing forces. In some cases, the first magnetic unit may be a shield, such as a direct current shield, that protects one or more components from a magnetic field of the second magnetic unit.

  • Patent number: 8702084
    Abstract: A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to bring each hook digit of the second holder in pressure abutment with the magnet block at a higher level than each hook digit of the first holder for thereby holding the magnet block in place on the platform.

  • Patent number: 8702078
    Abstract: A magnetic tool to enable a robot arm to grip a metallic workpiece includes a hollow housing having a coupling member adapted to attach the tool to the robotic arm. A sleeve depends from the housing having a shaft slidably received therein. The shaft has a first end disposed in the housing and a second end extending axially outwardly from an open end of the sleeve. A magnetic member is disposed on the second end of the shaft. The magnetic member includes a main body having a cavity formed therein. A magnet is slidably disposed within the cavity and attached to an actuator adapted to adjust the distance between the magnet and an inner surface of a magnetic face of the main body of the magnetic member to vary the magnetic attraction force at the magnetic face.

  • Patent number: 8668191
    Abstract: Because an electromagnetic chuck supplies current to a specific microcoil among a plurality of microcoils and makes an object exert an electromagnetic force working together with a magnet of the object, the object can be held in a state where the object is set at a desired position (a position that corresponds to the microcoil to which current has been supplied) on a base surface. Further, by gas that blows out from a gas supply passage, a levitation force is given to the object, which can reduce effects of a friction force that acts between the object and an upper surface of the electromagnetic chuck when the position of the object is set.

  • Patent number: 8632064
    Abstract: A positioning system having a base, a manually movable end effector and a first joint interposed between the base and the end effector is disclosed. The first joint may comprise a proximal portion and a distal portion coupled together by magnetic attraction and configured to be intermittently separated by a pressurized gas cushion. The first joint may be configured to be changeable between a movable state and a fixed state. In the movable state, the proximal and distal portions are separated by the pressurized gas cushion and are movable relative to each other. In the fixed state, the proximal and distal portions contact each other and relative movement is thereby impeded. Methods of precisely positioning an end effector may include providing a device having a base, a first joint located distally from the base, and an end effector located distally from the first joint.
