AccuEye™ Through Hole Parts Automatic Vision Comparative Inspection System

AccuEye™ Through Hole Parts Automatic Vision Comparative Inspection System Description:

Low cost Machine Vision Inspection system for Through Hole Inspection. Automatic Comparative Inspection (ACI) for Top and Bottom side in one pass.

AccuEye™ is a machine vision system designed for through hole component inspection. The design of the system is radically different from the traditional Surface Mount Technology (SMT) inspection machine.

AccuEye™ is not data driven but uses images of a known good board to compare with the incoming production boards. The idea is very similar to optical comparator and hence the name Automatic Comparative Inspection machine (ACI). The ACI is particularly suitable for through hole components inspection because of the diverse component geometry of the through hole components. While it is not data driven, it retains some of the attributes of a surface mount inspection machine such as image offset compensation using fudicials.

Top/Bottom Inspection in one pass

The AccuEye™ is designed to accommodate top and bottom cameras installation. Users can inspect top side and bottom side of the assembly simultaneously.

Wide Field of View for large Components

Unlike surface mount components which need to be placed precisely onto the printed circuit board, the location of the through hole can vary greatly because of the flexible lead. The AccuEye™ is designed to search for the component in a wide search area and then compare with the know good sample.

The wide Field of View can accommodate component up to approximately 150mm sq.

Conveyor inlet Height and Optics  to handle tall components up to 90mm

The conveyor inlet and outlet are opened up to 90mm above the conveyor to accommodate tall through hole components. The 700mm camera focal distant allow camera focal depth of up to 100mm.

Custom conveyor inlet height can be modified up to 130mm to accommodate even taller components than the standard inlet height would allow if needed.

Available Heavy Duty Chain Conveyor

Available chain conveyor to handle up to 10Kg payload such as pallet carrier for wave soldering. Light duty anti-static belt driver board edge conveyor is standard to accommodate small board. Conveyor Max width up to 510mm for the Large Board machine (L-1000).

Image data Storage

AccuEye™ can optionally store all or some of the images to either local or network storage. An optional barcode scanner can be installed traceability purpose so that user can associate the board serial number with images in storage.

Simple Design for ease of maintenance

The only moving part in the AccuEye™ system is the conveyor. Lighting is provided by LED light on four sides at high incident angle to prevent reflection. Bottom lighting is provided by fixed mounted LED light boxes. All the control functions are custom designed into a single controller board for ease of maintenance.

Fast Automatic Comparative Inspection Algorithm

Utilize Massive Parallel Algorithm for image comparison. Typical throughput per image is about 2-3 seconds.

Ease of Programming with Offline Programming capabilities

Inturitive software with touch screen monitor to ease programming. Inspection programs can be set up offline to reduce line down time.
