The OL-MRD-3A20 Automatic Particle Indentation AOI Inspection Machine, developed by Shenzhen Olian Automation Equipment Co., Ltd., represents a cutting-edge solution for detecting conductive particle indentations, offsets, distribution uniformity, and other defects in IC/FPC components on panels ranging from 0.96 to 10.1 inches. This article delves into the machine’s functionalities, technical specifications, and operational aspects.
Functional Description
The OL-MRD-3A20 is designed to automatically inspect and determine the quality of Bonding results (OK/NG) for COG, FOG, and COF panels. It detects defects such as foreign materials and cracks during the manufacturing process. The machine comprises several key components:
Feeding Belt: Transfers panels from the previous process into the equipment.
Loading Arm: Receives panels from the feeding belt and transfers them to the inspection platform.
Mark Alignment Camera: Mounted on the loading arm, it captures panel markings to correct product positioning.
Inspection Platforms: Two platforms equipped with cameras to scan and capture IC/FPC images for analysis.
Line Scan Camera: Performs IC scanning with auto-focus capability.
Unloading Arm: Moves inspected products to either the OK or NG discharge belt.
Discharge Belts: Separate belts for OK and NG products, with the NG belt requiring manual sorting.
Work Process
Panel Loading and Alignment: Panels enter the machine via the feeding belt and are transferred to the inspection platform by the loading arm. The Mark alignment camera captures panel markings to adjust positioning.
Indentation Inspection: The inspection platform moves the panel to the camera’s position, which scans and captures IC/FPC images for analysis, determining OK/NG results.
Panel Discharge: After inspection, the unloading arm moves OK products to the discharge belt and NG products to the NG belt for sorting.
Dual-Station Operation: When both stations are active, the camera alternates between platforms for continuous inspection.
