1. GENERAL

A high-speed modular mounter FX-3RA has been designed to match up with a

KE-3010/3020V/3020VR, and “A” of the model name indicates “affinity” and “advanced.”

This machine inherits the flexibility performance under the concept that has been built up from

the KE-Series mounters, and it is a modlular mounter that can be used more easily and more

economically and features further expandability and compatibility as an evolved model of the

FX-Series machines.

This mounter is equipped with two component placement stations, on each of which two

heads having six component placement axes pick up and place components alternately.

In addition, the linear motor driving system is used in its X-Y gantry structure to realize the

very short cycle time without any problem.

Use of an electric feeder realizes high-accuracy component supply.

In addition, combination of a production support system, with this mounter allows you to

manage and optimize various types of tasks and information on production with a Juki

mounter(s) and a JUKI dispenser(s) for each floor (that is, the production site) collectively.

This comprehensive management system supports you to reduce cost, and to improve

productivity and product quality effectively.

2. FEATURES

High Precision and High Speed Placement of Components

① An FX-3RA consists of two stations, four beams and four heads, and the heads on two

stations located on the left and right sides and those before and after these stations

alternately pick up/place components on boards.

A new type of linear servo motor is used to control the XY-axes. A high-precision linear

scale whose resolution is 1 μm offers full-closed loop control to place a component on a

board at high speed and highly precisely and secures its reliability for a long time.

② After components are picked with six nozzles at the same time, the components are

recognized on the fly at a time while the heads are moving to the component placement

positions to place the components on boards at high speed.

③ Automatic tool change unit (ATC) allows nozzles for six heads to be replaced at the same

time.

④ The Flexible Calibration System (FCS), which allows a mounter itself to recognize a

component placement position error and correct it, can maintain the component

placement accuracy that is realized at the factory or control the component placement

accuracy after the line configuration is changed. (Option)

⑤ A stepping motor is used as a board transporting motor of all buffers and stations, and

speed is controlled independently.

Improvement of Availability

① Use of a new board detection system does not require any adjustment of the sensor

position to detect a board having a notch.

② The time required for changeover is shortened and the number of component pick-up

errors is reduced thanks to the automatic teaching function of a component (supplied with

a paper tape whose component type is from 0402 to 3216) pick-up position. In addition.

③ The HMS that is provided as standard permits checking and teaching the pickup height.

Low Frequency of Failure Occurrence / Low Component Lost Rate

① Since the laser unit continues monitoring the component pick-up condition until just before

a component is placed on a board, it allows you to check whether a component drops or

not.

② The function of self-calibrating the timing of releasing the vacuum pressure prevented the

components at a placement moment from being brought back.

③ Driving the motor at the PWBs supports (supporting of a PWB) resulted not only in

preventing the components from being vibrated at unclamping the PWBs to avoid their

derailing out of the production lines after placed, but also curtailing the times of clamping

and unclamping the PWBs.

④ Since a vacuum pump is adopted, the air consumption can be reduced and the

component pickup stability has been improved.

⑤ The component pick-up position automatic correcting function of an electric tape feeder

improves the component pick-up position accuracy, and this allows the mounter to pick up

a component stably.

⑥ As a process of component measurement operation performed while Component data is

being created, components are returned to the feeder from which they were picked up

after measurement.

⑦ The component placement error preventing function, production support system is

provided: this function prevents a component placement error from occurring due to a

feeder-setting mistake. production support system is also a traceability function, and this

allows you to analyze the component production history and to track the production status.

⑧ Since a placement monitor is added, the camera installed in the head section can

photograph the status of component pickup/placement, thereby enabling simplified

inspection.

Improvement of Versatility

① An electric exchange trolley and mechanical exchange trolley can be used together for

each feeder bank. (Refer to a chapter 6-1. A list of feeder bank specifications, for

specifications of the feeder banks that can be used together.)

② Placement of 0402 components with a laser align sensor (LNC60/61) is supported as

standard.

③ Employing a new type of lighting system resulted in enhancing both recognizing the

marks on the flexible PWBs and the same via the pattern matching function. The function

of recognizing the area fiducial marks also made it possible to place a multiple number of

components upon a set of mark corrections.

④ As the board size, 410 mmｘ360 mm, 510 mm×360 mm and 610 mm×560 mm are

supported. When you add an option for a longer-sized board to the mounter, it supports

up to 800 mm as the X-dimension.

⑤ A bad mark indicating a defective circuit can be detected with an OCC camera or a

dedicated bad mark reader (option). Information on a bad mark read with the IN side

station is conveyed to the OUT side station, and this shortens the time for recognizing a

bad mark.

⑥ For multi-circuit boards, the bad mark recognition time can be omitted by a function that

specifies a circuit to place.

⑦ The area bad mark recognizing function allows the mounter to skip placement of a

component in the particular area of a board.

⑧ A LNC60/61 head can recognize up to □ 33.5 mm component.

⑨ The OCC image is “superimposed” on the screen, so you can perform a teaching

operation easily just by touching the desired direction pointer.

High Flexibility

① Program data created with a conventional CX, FX or KE-series mounter can be loaded to

these mounters.

② An idle carryout can be operated at a state of freeing the servo motors for heads and X/Y

axis.

③ Combination with the Production support system allows you to create a production line

including an existing mounter model and to create a production program for the entire line

with an Production support system client.
