Semi-Automatic Laser Marking Station

Precision Laser Marking Solution for Large Bearing Components

Karvi Engineering & Consultancy offers a specially engineered Semi-Automatic Laser Marking Station for large-size CRB bearings, designed for precise, repeatable, and permanent marking of bearing components.

The machine combines manual job loading and size setting with automatic fixture positioning and servo-controlled laser focal length adjustment, providing an economical and flexible solution for handling a wide range of bearing sizes.

The system is designed as a standalone industrial laser marking station with provision for integration of a Keyence laser marking system.

How the System Works

1. Manual Bearing Loading: The operator manually loads the bearing onto the selected horizontal or vertical fixture.
2. Manual Size Setting: The fixture guides and locating arrangement are manually adjusted according to the bearing OD and width.
3. Position Selection: The operator selects the required Horizontal or Vertical Marking Mode through the HMI.
4. Automatic Horizontal Positioning: The selected fixture automatically moves horizontally to the predefined laser marking position using a pneumatic cylinder-driven sliding mechanism.
5. Automatic Focal Length Adjustment: The servo-controlled Z-axis automatically positions the laser head at the required focal distance according to the selected job parameters.
6. Laser Marking: The bearing is marked automatically according to the programmed marking data.
7. Return to Loading Position: After completion of marking, the fixture returns to the operator-accessible position.
8. Manual Unloading: The operator manually removes the finished bearing and loads the next component.

Two Flexible Bearing Marking Positions

Horizontal Position – Face Sitting

The bearing is placed horizontally on its face on an adjustable fixture. This arrangement is suitable for marking the required upward-facing surface of the bearing or bearing component.

Features

• Adjustable guides for different bearing diameters
• Manual size adjustment
• Pneumatic locating cylinder
• Secure and repeatable positioning
• Quick-change fixture arrangement
• Automatic transfer to the laser marking position

Vertical Position

A dedicated vertical fixture allows the bearing to be held in an upright orientation for marking applications requiring an alternative component presentation.

The fixture incorporates:

• Adjustable supports and guides
• Manual size setting
• Pneumatic locating arrangement
• Repeatable bearing positioning
• Quick-change capability

Bearing Handling Capability

Marking Capabilities

Depending on the laser marking system and customer requirements, the machine can be configured for marking:

• Company logos
• Bearing numbers
• Part numbers
• Serial numbers
• Batch numbers
• Manufacturing codes
• Date and time
• Alphanumeric text
• Data Matrix codes
• QR codes
• Traceability information
• Customized marking patterns

Advanced Automation Features

Automatic Horizontal Fixture Positioning

Once the operator selects the required marking orientation, the corresponding fixture is automatically moved to the correct marking position.

Servo-Controlled Laser Head Positioning

The laser head is mounted on a precision vertical slider with servo-based Z-axis control for automatic positioning.

Automatic Focal Length Adjustment

The system automatically adjusts the laser head height to maintain the required focal distance for different bearing sizes and job heights.

Recipe-Based Operation

Job parameters can be stored as recipes for repeat production, helping reduce setup time and improve process repeatability.

Control & Automation

The machine is designed with an industrial automation architecture incorporating:

• Siemens PLC
• Siemens HMI touch panel
• Industrial computer with protective enclosure
• Servo-controlled Z-axis
• Pneumatic horizontal positioning system
• Pneumatic fixture locating cylinders
• Automatic pneumatic door control
• Machine status indication
• Alarm and diagnostic functions
• Manual and automatic operating modes

Safety Features

Operator and equipment safety are integral to the machine design.

The system can incorporate:

• Safety door interlock switches
• Safety light curtains
• Emergency stop push buttons
• Safety control circuit
• Personnel access protection
• LOTO – Lockout/Tagout provision
• Tower light with audible buzzer
• Laser marking safety enclosure
• Interlocked laser operation
• Electrical and pneumatic isolation provisions

Laser operation is permitted only when the required safety conditions and machine interlocks are satisfied.

Robust Industrial Construction

The machine is designed for demanding industrial production environments.

Base Structure: Heavy-duty MS fabricated structure with powder-coated finish.

Top Structure: Industrial aluminium profile enclosure.

Machine Enclosure: Fully guarded working area designed to provide safe operation and controlled access.

Mobility: Heavy-duty castors with a locking arrangement for positioning and maintenance convenience.

Fume Extraction System

Provision for an industrial fume extraction system helps remove fumes and airborne particles generated during laser marking.

This contributes to:

• Cleaner working environment
• Better visibility inside the marking chamber
• Protection of machine components
• Improved workplace conditions
