The MHEV Bush Pressing & Laser Marking System is a fully automated, intelligent manufacturing solution designed for precision assembly, real-time load and torque monitoring, and complete production data traceability.
It combines pneumatic press control, automated screw tightening, variant detection, and laser marking — ensuring total quality control and compliance with Industry 4.0 standards. System Overview
System Overview:
This machine performs bush pressing, screw tightening, and laser engraving operations on MHEV components in a single integrated cycle.
The pneumatic pressing system, equipped with a high-precision load cell, measures and records the applied pressing force, while the auto screwdriver captures torque and angle feedback for every fastener.
An Omron smart camera identifies the part variant, ensuring the correct operation sequence before proceeding to the marking stage.
All operational data is automatically logged in a centralized database for traceability and analytics.
Key Features:
- 1. Precision Bush Pressing
- Pneumatic press with high-accuracy load cell feedback.
- Real-time display of load vs. stroke for quality verification.
- Configurable pressing limits with automatic rejection for out-of-tolerance values.
- Data recording for each part including press force, cycle time, and operator ID.
- 2. Automatic Screw Tightening
- Integrated auto screwdriver with torque and angle control.
- Pass/Fail validation based on programmed tightening curves.
- Cycle traceability linked to the component barcode.
- Servo-based or DC-controlled systems supported for multi-variant tightening.
- 3. Variant Detection & Poka-Yoke
- Omron vision camera identifies part variants and verifies correct assembly orientation.
- Automatic interlock prevents wrong-part processing.
- Visual and audible alerts for NOK or mismatch conditions.
- 4. Laser Marking & Traceability
- Laser marking of QR code or alphanumeric serial on each OK part.
- Integration with centralized traceability server for record storage.
- Automated log of date, time, part ID, torque, and press force in CSV/SQL format.
- Supports barcode-based retrieval of part history and process data.
System Benefits:
