KGB-M7163-00X Ejector for YAMAHA YV100XG pick and place machine

KGB-M7163-00X Ejector for YAMAHA YV100XG pick and place machine

The YAMAHA KGB-M7163-00X Vacuum Ejector is a pneumatic vacuum-generation component used in YV100XG SMT pick and place machine applications. Its function is to support the negative pressure required by the placement head and nozzle system during electronic component pickup and transfer.

Stable vacuum performance is important for maintaining consistent component handling during SMT production. When the ejector becomes worn, contaminated, restricted, or unstable, the machine may experience weak suction, repeated pickup failures, component drops, or abnormal vacuum response.

The KGB-M7163-00X is suitable for SMT production factories, equipment maintenance departments, service companies, and spare-parts distributors requiring replacement components for YV100XG equipment. For accurate ordering, buyers are advised to confirm the original part number, machine model, and installed component configuration before purchase.

Cause

Why Does an SMT Vacuum Ejector Need Replacement?

Vacuum ejectors operate repeatedly during component placement. Continuous pneumatic cycling and production exposure can gradually affect vacuum performance.

Common causes include:

One common symptom is an increase in component pickup errors even when the nozzle and feeder appear normal.

Another symptom may be inconsistent suction, where some components are successfully picked while others are not.

However, an ejector should not automatically be considered defective whenever a pickup problem occurs. Maintenance personnel should also inspect the nozzle, tubing, fittings, filters, pneumatic valves, and compressed-air supply.

Solution

Restore Stable Vacuum Performance

When troubleshooting confirms that the existing vacuum ejector no longer provides reliable performance, replacing it with the correct compatible part can help restore stable machine operation.

The KGB-M7163-00X Vacuum Ejector provides a replacement solution for YV100XG applications using this part number.

A recommended maintenance procedure includes:

1. Confirm the machine model.
2. Check the original ejector part number.
3. Inspect the nozzle and vacuum path.
4. Check hoses and fittings for air leakage.
5. Confirm compressed-air supply condition.
6. Compare vacuum response with normal machine performance.
7. Replace the ejector if deterioration is confirmed.
8. Perform pickup and placement testing after installation.

Maintenance Benefits

Keeping critical pneumatic components available in spare-parts inventory can be especially useful for factories operating several YV100XG machines.

Specifications

Important Ordering Note

External appearance alone should not be used to identify an SMT machine spare part.

For accurate selection, confirm:

• Original part number
• Machine model
• Installed part appearance
• Connector or pneumatic-port arrangement
• Quantity required
• Machine configuration

If available, a clear photo of the original ejector is recommended before order confirmation.

Application

The KGB-M7163-00X vacuum ejector is intended for YV100XG SMT equipment maintenance and vacuum-system servicing.

Typical Application Environments

The component is particularly useful where production continuity is important and vacuum-related faults must be corrected quickly.

Typical Problems Related to Vacuum Performance

A weak or unstable vacuum system may result in:

• Components remaining in the feeder
• Components dropping during head movement
• Repeated pickup attempts
• Increased machine alarms
• Intermittent suction
• Reduced placement efficiency
• Higher operator intervention
• Increased machine downtime

These symptoms can have multiple causes, so proper diagnosis is recommended before replacing the ejector.

How It Works

Vacuum Generation Principle

The ejector uses compressed air to generate negative pressure.

The general working sequence is:

Compressed Air → Vacuum Ejector → Negative Pressure → Nozzle → Component Pickup

During production, compressed air enters the ejector. Internal airflow creates a low-pressure area, producing vacuum.

This vacuum is supplied to the nozzle system.

The nozzle then uses suction to pick the electronic component from the feeder.

While the placement head moves, stable vacuum helps keep the component securely attached to the nozzle.

At the programmed PCB position, the component is released for placement.

This cycle is repeated continuously during machine operation.

Why Stable Vacuum Is Important

During high-speed placement, the component may be exposed to acceleration, rotation, vision inspection, and rapid head movement.

Insufficient vacuum can reduce component holding stability.

For this reason, the ejector works as an important part of the machine's pneumatic component-handling system.

How To Choose

1. Confirm the Part Number

The first selection reference should be:

KGB-M7163-00X

Matching the exact part number helps reduce ordering mistakes.

2. Confirm the Machine

Verify that the machine is a YV100XG pick and place machine using this ejector configuration.

3. Compare the Original Part

Before purchasing, compare the original component with the replacement.

Recommended comparison points include:

4. Diagnose the Vacuum System

Before replacing the ejector, inspect other related components.

Possible vacuum problems may also come from:

• Clogged nozzles
• Dirty filters
• Vacuum hose leakage
• Loose fittings
• Pneumatic valve malfunction
• Low compressed-air pressure
• Damaged seals

Correct diagnosis helps avoid unnecessary replacement.

5. Consider Spare Inventory

Factories running several SMT machines should consider maintaining commonly used vacuum-system parts in stock.

This can help maintenance teams respond quickly to unexpected production failures and reduce emergency procurement delays.
