High Precision Automatic Optical Vision Video Measurement Machine For Mobile Screen Inspection

Product Introduction

AT series Automatic Vision Measurement System is designed specifically for large scale repeated measuring, it is with high speed, high effcient and powerful.

The features in the VMM control system of AR- 3 are as follows:

• Adopts a special purpose-built processor (ASP) to significantly reduce the number of electronic circuits and parts to improve reliability.
• Adopt a single circuit board structure, in order to greatly reduce the number of wiring to improve reliability.
• High speed, energy saving and high precision fully closed-loop AC servo control system, which can provide positioning accuracy up to 1 μm, in order to minimize the possible factors affecting measurement repeatability.
• 21 orders of high precision geometric stereo spatial error compensation.

Technical Specification

Features

• X , Y , Z axis of the Absolute Linear Scale is independent researched and developed, with a resolution up to 0.01 μm.
• F3 high precision closed loop auto zoom lens.
• The special designed motion controller of Vision measuring machine using Ethernet transmission, which is efficient and reliable system, can solve the disadvantage of unstable USB transmission.
• High-resolution SONY CMOS sensor of image processor to ensure the image is clear and without smearing.
• The up light source using eight areas partitioned independent control lighting system, and the light-emitting element using low- attenuation LED to extend working life.
• Independently developed multi-function 2D and 3D measurement software, the measurement results can be output to DXF, Word, Excel, PDF and other formats.
• Machine can run in 24 hours continue operation.
• 3 axis precision linear guide, precision drive system and CNC control system.
• Precision granite machine body with high accuracy and stability.
• New design for machine work table, in order to prevent pinching during operations

F3 high precision closed loop auto zoom lens

Combine with the high precision and high resolution ring scale developed and designed by Easson's F3 lens, full closed-loop position feedback, the image multiple repetition error caused by the gear transmission gap is eliminated to Improve the repeatability of the overall measurement.

21 Orders Volumetric Compensation

Easson Vision Measurement Machine used with AR series Network control System which is included 21 orders volumetric compensation, with Ultra high speed linear encoder reading and built-in EAD (absolute code decoder) allow AR series system to use our AS-80 high precision absolute scale, providing high accuracy and high resolution measurement.

2D / 3D Multiple Measurement

Easson three series of vision measuring machines can cooperate with the UK Renishaw high-precision touch probe for 2D / 3D multiple measurement. The 3D measurement of the probe can be mixed with the 2D measurement of the imaging system. The same coordinate system is used for 2D / 3D measurement in perfect and easy combination.
