In a component mounting work area, two electronic circuit boards are placed in a zigzag manner and components are mounted independently on each board. Two sets of working drive units, board conveying/holding devices, recognition cameras and so forth are also arranged in the work area. The board conveying/holding devices for holding boards are moved to positions close to component feed units, and components are mounted in respective mounting areas.

Device and method for conveying and holding plate-like member

A first mounting unit and a second mounting unit capable of performing component holding, component recognition, and component placement for two boards independently of each other are provided. A first conveyance path for loading and unloading the first board, and a second conveyance path for loading and unloading the second board, are independently arranged.

Component mounting apparatus and method

In a component mounting work area, two electronic circuit boards are placed in a zigzag manner and components are mounted independently on each board. Two sets of working their drive units, board conveying/holding devices recognition cameras and so forth are also arranged. The board conveying/holding devices for holding boards are moved to positions close to component feed units, and components are mounted in respective mounting areas.

Device and method for mounting parts

An apparatus and a method for mounting electronic components are provided which shorten a cycle time required for mounting and enable a component mounting machine to be arranged in a small area. There is provided a controller, so that a retreat control for a second electronic component is performed to a second component feeder so as to avoid an interference if a first electronic component or a component holder interferes with the second electronic component of the second component feeder because of movement of a mounting head. The time conventionally required for moving up and down a component holder can be reduced, and moreover the need of uselessly moving along a detour at a time of moving the mounting head is eliminated. The cycle time can be shortened, and eventually costs can be reduced.

Electronic component mounting apparatus and method

Device for transferring/holding sheetlike member and its method

Disclosed are a component recognizing method and apparatus, and a component mounting method and apparatus, by which components with various heights held by a plurality of nozzles can be recognized continuously. The drive of a head is transmitted to nozzles, with surfaces to be recognized of components being controlled so as to be positioned in a recognizable range during respective recognizing operations of the components, and a continuous recognition is thereby made possible. The adjustment of heights of the surfaces to be recognized during the recognizing operations of the components is achieved by one drive unit and a plurality of drive transmitting units.

Component recognizing method and apparatus, and component mounting method and apparatus

There is provided a circuit board fixing table having a structure in which no vibration or shock is applied to a transport motor when a circuit board is fixed and an electronic component mounting apparatus utilizing the circuit board fixing table and capable of mounting electronic components without causing operational failures during transportation. A circuit board fixing table for transporting a circuit board placed on transport belts to a predetermined position and fixing it with an elevating fixing device, the table having a transport motor provided separately from a support member for the transport belts for driving the transport belts and power transmission mechanisms A and B for transmitting a driving force of the transport motor to the transport belts.

Circuit board fixing table, circuit board fixing method and electronic component mounting apparatus

Two or more parts feeding sections are provided, and in each of the parts feeding sections, identical combinations of parts cassettes aligned in the same arrangement are prepared. If one or more type of components that are to be picked up at one time by a plurality of suction nozzles is exhausted, the mounting head moves to the other parts feeding section, which provides the same combination of components for all the suction nozzles to pick up the components at one time, so that the mounting operation can be continued without stopping the apparatus for replenishment of components.

Electronic component mounting method

When a nozzle is selected, a piston rod ( ) of a nozzle selecting cylinder ( ) positioned at a lower end position unfailingly forms a gap (A) with an upper end of a nozzle elevating shaft ( ) so that the piston rod of the cylinder ( ) is not brought into contact with the nozzle elevating shaft at the time of nozzle selecting. Only when an elevating member ( ) is lowered by a drive by an elevation drive motor ( ), the piston rod ( ) is brought into contact with the nozzle elevating shaft ( ).

Part sucking nozzle lifter

A component mounting apparatus and method allows for components supplied from component supplying members to be simultaneously or continuously held by component holding members without being affected by positional displacements of the component holding members relative to a head, a positional displacement of the component supplying members or the like. With a positional displacement amount (&Dgr;y) along a Y direction relative to a reference position of a nozzle taken into account, at a component supply cassette, driving a motor for moving components one by one along the Y direction to a component supply position is controlled, thereby positionally adjusting a component at the component supply position and absorbing the positional displacement amount.

Electronic component mounting apparatus using duplicate sources of components

The safety device includes an opening/closing cover which isolates a takeout part and an accommodating part of a component feeder unit from each other and which has a sensor for detecting a closed state. The component feeder unit includes the component accommodating part, a feed-out part and the takeout part, and sensors for transmission through voids common to the plurality of set component feeder units. Upon a detection by any one of the sensors during the operation of the machine, the machine is halted. For replacement of the component feeder units, a changeover switch is pressed, by which the detecting function is paused for a specified time period. Thus, a safety device which allows the component feeder units to be replaced even during the operation of the machine can be obtained.

Component mounting machine and safety device thereof

In a component mounting apparatus, a component (,) is held, positioned and mounted at a predetermined position of a member (,) to be mounted. After the component (,) is mounted to the member (,), a component holding member (,) is raised by a distance corresponding approximately to a push-in amount by which the component holding member (,) has been moved down to mount the component, then stopped to retain the component (,), is kept in this state while retaining the component for a fixed time, and is raised again to a predetermined position.
