Introduction

1.1. General

KE-3020 and KE-3020R, which inherit the flexibility in performance under the modular

concepts that have been built up so far in order to keep a key position of the future flexible

modular line, are general-purpose mounters with a multiple-head in an one-by-one system

that further improves the safety, reliability, maintainability and economy.

KE-3020 and KE-3020R, having a good affinity for high-speed modular mounter FX-3, can

construct the line that operates stably attaching electric feeders. Moreover, KE-3020 and

KE-3020R can also use the component supply unit (tape, stick, or bulk feeders) and

production program used in the existing KE series. This permits a reduction of installation

cost and a smooth startup of the system. *1

Additionally, combination of this machine and floor productivity operating system to be used

with the JUKI mounters and dispensers, allow you to manage the productions not only per line

but also per floor. The floor productivity operating system manages and optimizes the

information and jobs for a whole manufacturing floor comprehensively to provide you

improved productivity, better manufacturing quality, and cost reduction. *2

supply unit."

specification of each system.

Features

High Precision and High Speed Placement of Components

① High-speed placement is available thanks to the new concept laser alignment sensor

(LNC60) that can recognize six nozzles simultaneously.

② KE-3020 consists of seven nozzles: six nozzles of LNC60 head and an IC head (CDS),

KE-3020R consists of seven nozzles: six nozzles of LNC60 head and an IC head (FMLA).

③ The independent AC servomotor is used to move up/down (Z axis) or rotate (theta axis)

each nozzle: this feature enables high-speed and high precision placement of

components regardless of the used placement pattern.

④ Ball screw drive in both X and Y axis enables smoother and more stable acceleration and

deceleration or stop than the conventional belt drive.

⑤ The time required for image recognition is shortened thanks to the new image recognition

system.

⑥ 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)

Effective tact

① Automatic tool change unit (ATC) allows nozzles for six heads to be replaced at the same

time.

② A stepping motor is used for the transport motor of the IN/OUT buffer. This permits

exerting independent speed control.

Operation rate

① In addition to the conventional mechanical tape feeders (ATF series), electric tape feeders

can be used. They enable the tape splicing and the reduction in machine stop when the

stocked components run out.

② If the non-stop function is used, it allows this series of products to automatically pick up

components from the rear side when the stocked components run out at the front side

during production without stopping the mounter and to replenish the feeder where the

stocked components run out with components. (Option)

③ A DTS (TR-1SNR, TR-1EB), MTS (TR-5SNX, TR-5DNX) or MTC（TR-6SNX/6SXLX、

TR-6DNX/6DXLX）can be used for tray components that run out frequently.

④ Fixing was made with Dial screws in order to make it possible to adjust the arrangement

of transport sensors for carrying in-and–out the PWBs, with no use of any tool.

⑤ 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.

⑥ The HMS equipped as the standard device allows you to check the component pick-up

height and to perform a teaching operation easily to prevent the operation rate from being

lowered by a component pick-up error.

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 The support table that holds a PWB during the production is driven by motor so that the

PWB is unclamped without being vibrated, which means that the placed components are

not shifted. The time of clamping and unclamping the PWB has been reduced as well.

④ When you select the high-density component placement function (Pick-up Position

Preference mode), the mounter can pick up the center of a component correctly to

prevent the tip of a nozzle from being in contact with the adjacent component when

components are already placed in the limited area.

⑤ A high-resolution (260,000 pulses/rotation) AC servomotor, although it is very small: □ 15

mm, is attached on all theta axes to improve the component placement accuracy.

⑥ Use of a vacuum pump greatly improves the stability of air supply available when the

machine picks up a component.

⑦ By attaching an ionizer to the ceiling of the machine, the ion in the machine is well

balanced and static electricity in PWBs or SMT components is removed at high speed.

⑧ A stable pick-up is achieved by improving a pick-up position accuracy with an automatic

pick-up position correction function for electric tape feeders.

⑨ For components fed by a shuttle of a matrix tray changer (MTC), such defective

components as crocked legs and the like can also be collected automatically into the

original trays

⑩ As 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.

⑪ To prevent a component placement error from occurring due to a feeder-setting mistake,

the production management system, which is a function that prevents a component from

being placed at a wrong position, is provided. In addition, the traceability function of the

production management system allows you to analyze the component production history

and to track the production status.

* The production management system is necessary to use the function that prevents a

component from being placed at a wrong position.

Machine stability at installation

① A “Super Foot,” which is not easily affected by the floor condition, is provided as an

option.
