A method of preventing a nozzle or nozzles from dropping in a component mounting apparatus include gripping the nozzle structures with pivotal levers that are biased to a closed position. The pivotal levers are released after activation of the nozzles to permit appropriate movement for picking up, inspecting, orientating and locating electronic components on a substrate with the nozzles. During the operation of the mounting head, the levers are maintained in a release position against a biasing force and at the end of the operation, the biasing force can then cause the levers to close and support the nozzles in a gripping manner.

An electronic component mounting method which employs a first air feed device connected to an air passage at one end part of a spline shaft, and a second air feed device connected to the air passage in the vicinity of the other end of the spline shaft. The first and second air feeds function to supply air to the air passage to return an interior thereof to atmospheric pressure. The time required to return the vacuum pressure in the air passage to atmospheric pressure can be shortened by the use of the two separate air feeds.

When two mounting units for performing a series of component mounting operations constituted of component holding, component recognition, and component placing are arranged, operational control is executed so that, while a component recognition or board recognition operation is performed in either one of the two mounting units, the component placing or component holding operation is not performed in the other of the mounting units.

A voice coil motor is attached to a shaft, that is installed in a component holding head, to drive the shaft in an axial direction. Also, a detecting device is arranged to detect movement of the shaft. The supply of power to the voice coil motor is controlled on the basis of a detection result of the detecting device, whereby movement of the shaft in the axial direction is controlled. The movement of the shaft in the axial direction is accordingly correctly known.
摘要:
A mounting head is provided with a pair of first levers which are pivotally connected so that the first levers can swing in an open and close direction and forced in the close direction by a compression spring so as to grip a shaft, a release pin for opening the first levers by engaging release grooves at an open/close end of the first levers, a second lever for driving the release pin toward the open/close end of the first levers by a driving means, and a spring for forcing the second lever in a direction opposite to the driving direction of the release pin. During an operation of the mounting head, the first levers are opened by driving the release pin with the second lever, only after the shaft is activated, and at the end of the operation releasing the drive of the release pin by the second lever, allowing the first levers to close and support the shaft in a gripping manner.
摘要:
A component mounting method including carrying in a circuit board to a component mounting position and carrying out the circuit board after component-mounting operation. The component mounting operation includes sucking up the component from the component feed section and moving the component to the mounting position, and mounting the component on a specified site of the circuit board. Also, a remaining-component discarding operation is performed to discard a component which remains at the suction nozzle during a specified time period following the component-mounting operation while the component mounting operation is stopped.
