The OL-COF-03A by Olian Automatic is a semi-automatic offline trimming machine designed for precision die-based cutting of Chip-on-Flex (COF) modules before bonding. It removes excess flex material or trims carrier frames from COF assemblies using custom-made dies, ensuring clean edges and consistent geometry for downstream assembly or packaging.
This machine is intended for post-bonding finishing only—it does not perform bonding, ACF application, or electrical testing.
Operation Principle
The OL-COF-03A uses a mechanical press actuated by dual-hand start buttons to drive a custom die set. The operator manually loads the COF module into the die fixture, presses both start buttons simultaneously, and the upper die descends to trim the part in a single stroke.
Cycle control: Fully mechanical with safety interlock
Actuation: Pneumatic-assisted press (implied by standard industrial design)
Tooling: Custom-made male/female dies, tailored to specific COF layout
Each die set is application-specific and must be ordered separately or fabricated per customer drawing.
Key Components & Safety Features
Start buttons: Two Φ24 push buttons, requiring simultaneous press for operation
Emergency stop: Φ22 mushroom-type switch for immediate shutdown
Die mounting platform: Rigid steel frame for stable cutting force
Manual loading/unloading: Operator places and retrieves parts by hand
The dual-hand start ensures hands are clear of the die area during operation, complying with basic machine safety standards.
Performance & Specifications
Max trimming area: Compatible with standard COF modules up to typical panel sizes (exact dimensions defined by die)
Repeatability: High, limited only by die precision and operator placement
Throughput: ~600–1000 pcs/hour (depending on operator skill and part complexity)
Power: Standard industrial single-phase 220V AC
Air supply: Required for press actuation (typical: 0.5–0.7 MPa)
Applications
Ideal for:
Trimming excess polyimide from COF ICs in reels
Cutting carrier tabs or tie-bars from COF strips
Final shaping of COF modules before panel integration
Repair or rework stations in display module assembly lines
Commonly used in LCD, OLED, and automotive display manufacturing.
Important Clarifications
Not a bonding machine – performs mechanical trimming only
Requires custom dies – not included unless specified
No vision system, no automation feed – fully manual loading
Offline operation – not integrated into inline production lines
