SI-G200 (B Head) Overview

SI-G200, chip parts mounter, has two heads installed on it.

This mounter has newly designed multifunctional heads in order to deal with the larger scope of parts, such as

odd-shaped ones. The configuration of this mounter’s control system for controlling its heads is the same as that

of SI-G200 (high-speed mounter).

This document explains the functions and features of SI-G200 (multifunctional mounter).

1. Functions of the Multifunctional Mounter

The multifunctional mounter has eight nozzles per head and can manufacture parts with dimensions of 1005 to

100 x 50 mm and a height of up to 13 mm. Described below are the features of the mounter for picking up,

recognizing, and mounting parts.

2. Features of the Mounter

Described below is the configuration of SI-G200 multifunctional mounter.

Head configuration : 2 heads (eight nozzles per head)

Recognition camera : PWB camera, pickup check camera, and fixed camera (wide and narrow

fields of view)

Supply section : 40 cassettes at the front and 40 cassettes at the rear (when converted into

8-mm cassettes)

Recognition method : Individual recognition, global recognition, and split recognition

Image processing method : Reflection recognition (Transmission recognition is not supported.)

Parts mounting : Normal mode and high-Accuracy mode

Nozzle changer : 8 changers x 3 sets per head

Options

Tray changer : 15 tray changers x 2

Tray changers can be installed only on the rear head.

When the tray changer option is selected, the number of cassettes to be

mounted is seventeen.

3. Sizes of Parts That Can Be Handled

There are restrictive conditions between camera types/lighting methods and parts. Select an appropriate camera

and a recognition method according to the size of parts or the shape and size of electrodes.

Parts may not be recognized correctly, depending on the shape of electrodes or the degree of reflection. In such a

case, take measures, such as switching a camera to use to another.

4. Basic Operations of the Multifunctional Mounter

The multifunctional mounter picks up, recognizes, and mounts parts in the same way as SI-G Series mounters

(high-speed mounters). Described below are the operations, features, and points to note of the multifunctional

mounter.

4-1 Operations in Automatic Production

The flow of pickup, recognition, and mounting of parts in automatic production is shown below.

Unless there are no special restrictions, such as the number of parts to be picked up simultaneously or

coexistence of Accuracy levels, continuous pickup is conducted according to the order of numbers defined

in machine model data.

When nozzle replacement is necessary during production, the nozzle replacement operation is conducted

before parts pickup.

Recognition is conducted according to the recognition method specified by part data.

Multiple recognition operations may be conducted in the same path.

For each of parts set in the high-Accuracy mode, the operation from recognition to mounting is conducted.

Parts set in the high-Accuracy mode are recognized according to their mounting angles.

Parts are mounted onto the coordinate positions specified by machine model data.

For each of parts set in the high-Accuracy mode, the operation from recognition to mounting is conducted.

When a pickup error or recognition error has occurred, an operation of disposing of parts is conducted after

this.

4-2 Fixed Camera Recognition Mark

Inflation or contraction of each section of the mounter due to temperature change causes the position of the

head to change during the movement of X and Y axes. Therefore, the change in the XY position needs to

be removed when parts are recognized.

During part recognition, change in the XY position due to inflation or contraction when parts move to

above a fixed camera causes an error in the posture or the position of parts. This influences the parts

mounting Accuracy of the mounter.

In order to remove this influence, when time specified in machine data has lapsed, the position of the

reference mark on the fixed camera is checked before parts are recognized by the camera, and the XY axis

position error when parts move to above the camera is compensated for.

The XY position when parts are mounted is removed when compensation with alignment mark recognition

is performed. Therefore, no other compensation needs to be performed.
