Introduction

To meet the challenge of diversification in the field of surface mount

technology, the FCP IV-3 offers parts location via an advanced vision

processing system, a split device table, a production support system (HELPS)

and many other advantages to produce a highly accurate, reliable placing

machine.

The FCP IV-3 has achieved, for a wide variety of parts, a placement rate of 0.15

sec/part. How to achieve precision placements at such high speeds has been

investigated from all angles. Based on the results of our investigations, we

have incorporated the following features into the FCP IV-3.

• The part rotation function has been divided into pre-theta and fine theta.

Pre-theta rotates the part 90° towards the correct angle, thereby reducing

the overall time required for placement.

• In the FCP-III the vision processing control and the control system for the

entire machine operated from the same CPU. In the FCP-IV (FCP-IV, FCP

IV-2, and FCP IV-3) series, the vision processing system operates

independently, using a dedicated CPU, enabling faster vision processing.

• The new gray scale vision system, which can see shades between black and

white, enables the machine to discern with much greater accuracy the

position of the part, which enables greater placement accuracy.

• When light is shone directly onto a part, there is no shadow and the body

will not hide things like J leads, which will be clearly seen and thus enable

greater placing accuracy (optional).

• The machine takes into account the height of the part in question and

automatically adjust the height of the XY table to reduce stress on the

placed part. Part heights are entered into Part data, which then feeds this

information to servo motors to adjust the XY table. Therefore, despite

simplicity of the nozzle structure the parts will always have a “soft

landing.”

• There are three types of nozzles (S, M and L) on one head. This means that

the FCP IV-3 can pick parts with a flat picking surface from sizes as small as

1005 to as large as 20 mm X 20 mm.

Chapter 1 Safety Guidelines

1. Safety Guidelines

Fuji made the safety of the operator one of the foremost priorities in the

designing of the FCP IV-3.

However, to ensure safety, the operator must follow the safety guidelines

described in this chapter.

1.1 Electrical Safety Guidelines

This section describes safety guidelines when working with the electric

power supply and transformers.

1.1.1 High Voltage Electricity Supply

Run the power supply cable through the opening at the bottom of

the machine on the left-hand side (when viewing from the front) as

shown in figure 1-1. Connect the three phase cables and the earth

cable to the primary side of the main breaker.

Fig. 1-1 Position of the Three Phase and Earth Cables

Before performing machine inspection, always disengage the main

power source. Even if the main breaker is off, the primary voltage

is still active, so operators should be very careful.

Also, the machine should never be operated with the door open as

shown in figure 1-1.

1.1.2 Checking the Transformer Connections

Remove the large attachment screws on the end cover on the left-

hand side of the machine and take the cover off. Check that the

main transformer is set to the specified input voltage. If the

transformer is set to an incorrect input value electrical parts may be

damaged. Figure 1-2 shows the positioning of the transformer taps.
