  • Patent number: 10687450
    Abstract: A component chuck device moves a pusher member downward when negative pressure is supplied, and holds a posture of a component by causing the pusher member to abut with an upper face of the component that is gripped in a gripping mechanism. Then, the component chuck device releases gripping of the component when supply of negative pressure is stopped, and a lead of the component is inserted into a hole of a substrate while holding the posture of the component by moving the pusher member downward while remaining abutted with the upper face of the component.

  • Patent number: 10368447
    Abstract: A chuck device is provided with multiple types of chuck claws clamping a component, a chuck claw switching mechanism switching the chuck claw in use among the multiple chuck claws based on the type of component to be clamped, and a driving mechanism causing the chuck claw subjected to the switching by a chuck claw switching mechanism perform a clamping operation. The chuck claw switching mechanism causes the respective chuck claws to move vertically independently of each other and performs switching of the chuck claw in use by a rotating cylindrical cam in a state where rotation of a tubular guide member placed on an outer peripheral side of a cylindrical cam is locked. A rotation locking member locking the rotation of the tubular guide member during switching of the chuck claw in use and a cam follower moving the rotation locking member are disposed in a mounting head.

  • Patent number: 10172269
    Abstract: A chuck device includes a plurality of types of chuck pawls clamping a component, a chuck pawl switching mechanism switching the chuck pawls in use among the plurality of types of chuck pawls in accordance with the type of the component to be clamped, and a driving mechanism allowing the chuck pawl switched by the chuck pawl switching mechanism to be put into a clamping operation. The chuck pawl switching mechanism is configured to use a cylindrical cam, the plurality of types of chuck pawls are placed at predetermined intervals around the cylindrical cam, a cam follower disposed in each of the chuck pawls is fitted into a cam groove in an outer peripheral surface of the cylindrical cam, and the respective chuck pawls are moved upward and downward independently of each other by the cylindrical cam being rotated.

  • Patent number: 10040205
    Abstract: In a suction nozzle which sucks and holds a component on a suction surface by using negative pressure air and detaches the sucked and held component from the suction surface by using positive pressure air, the positive pressure air and the negative pressure air used when the component is held and detached selectively flow through an air flow path. In addition, a rod is advanced and retracted toward the suction surface in an inside section of the suction nozzle. The rod protrudes from the suction surface by the positive pressure air flowing through the air flow path and is retracted to the inside section of the suction nozzle when the negative pressure flows through the air flow path.

  • Patent number: 9999168
    Abstract: A board conveyance device provided with multiple engaging sections that engage with a circuit board. When the conveyance direction is a first direction and the board is large, a claw out of two claws is set to a stopping state. A shuttle is moved up to the movement end on the downstream side in the first direction and two arms rotate. A lever rotates accompanying rotation of a rotating body to a disengaged position by a lever rotating section of a stopping device and an arm unit is able to be disconnected from a moving body. An arm holding section engages with an engaging section to prevent movement in the x direction. The moving body is moved in a second direction with the arm unit held by the stopping device. The claw is set to be in the stopping state and is not used in conveyance of the board.

  • Publication number: 20170291308
    Abstract: In a suction nozzle 66 which sucks and holds a component 150 on a suction surface by using negative pressure air and detaches the sucked and held component from the suction surface by using positive pressure air, the positive pressure air and the negative pressure air used when the component is held and detached selectively flow through through-holes 90, 94 and 96, air flow path 116, or the like. In addition, a rod 110 is held to be capable of being advanced and retracted toward the suction surface in an inside section of the suction nozzle. The rod protrudes from the suction surface by the positive pressure air flowing through the air flow path and is retracted to the inside section of the suction nozzle when the negative pressure flows through the air flow path. In other words, the through-hole, the air flow path, or the like is shared as a mechanism for moving the rod and a mechanism for sucking and holding the component by the suction nozzle.
