An electronic component mounting apparatus 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.

Apparatus for holding and mounting a component

A calibration jig for a component recognition device and a component recognition calibration method using the jig which can stabilize the mounting accuracy of a component to a to-be-mounted object and improve amount quality. An opening is formed at a to-be-picked up face of the calibration jig. A predetermined position of the calibration jig is recognized on the basis of the contrast between the picked-up face and the opening. The position of the calibration jig can be recognized with higher accuracy, so that a resolution of the component recognition device, etc. can be obtained with a higher degree of accuracy. Mount accuracy of the component to the object is thus stabilized and mount quality is improved.

Jig for calibrating component recognition apparatus, component recognition calibrating method using the jig, and component mounting apparatus using the jig

A component installing device comprises: a tray component supply section ( ) having a plurality of conjointly provided tray component supply mechanisms ( ) for moving selected trays ( ) from a storage position ( ) to a component supply position ( ), according to need, thereby providing the components ( ) accommodated therein for use; and a cassette component supply section ( ) having a plurality of mutually aligned component supply cassettes ( ) for carrying components in a tape cassette or a bulk cassette, and transporting said components to a component supply position ( ), one at a time, thereby providing said components for use. Components ( ) accommodated in the respective trays ( ) located at the component supply positions ( ) of the respective tray component supply mechanisms ( ) in the tray component supply section ( ), and components ( ) transported to the component supply positions ( ) of the respective component supply cassettes ( ) in the cassette component supply section ( ), are variously handled and installed at prescribed positions on a circuit board ( ) by means of an installing head ( ).

Part mounting apparatus and part supply apparatus

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.

Method of preventing a nozzle drop in a component mounting apparatus

According to the present invention, a control device and a circuit board moving device controlled in operation by the control device for holding a circuit board are provided, whereby the circuit board moving device is moved to bring a component mount position on the circuit board closest to a recognition device after the circuit board moving device is moved to bring the component mount position closest to a component feed position. In the state, a circuit board mark formed on the circuit board is detected, thereby recognizing a position of the circuit board. A transfer distance for the component by a component hold device from the recognition device to the component mount position is thus shortened, enabling high-speed mounting with higher accuracy.

Parts mounting method and apparatus

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.

Apparatus for holding component, apparatus for mounting component, and method for mounting component

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.

Device for securing a nozzle of a parts installer

A transmission mechanism includes a pressing stroke controller for changing the effective pressing stroke of each feed lever of a component feeder unit corresponding to a predetermined pitch of carrying electronic components in respective component feeder unit, whereby the vibration generated when the transmission mechanism is in operation is reduced. Adverse effects on a component feeder unit having small components thereon at a fine pitch which is susceptible to the vibration will be prevented, and the feeding speed can be increased to be more productive.

Electronic component feeding apparatus

A rotary body rotatable about a vertical axis thereof is set at a mounting head. A cam having a cam surface at a lower end thereof is arranged along the periphery of a lower part of the rotary body. Each of outer cylinders is rotatably set in the periphery of the rotary body, wherein each of nozzle shafts with each suction nozzle fitted at lower ends thereof penetrates each outer cylinder in a freely movable manner in an up and down direction. An engaging part for a rotary device is provided at an upper end of each outer cylinder, and an engaging device for the cam is placed at a lower part of each nozzle shaft projecting from a lower end of each outer cylinder.
