Mech-Eye UHP-140 is specially designed for demanding inspection and measurement applications in automotive and other industries. It can be used to inspect or measure position, gap, and segment difference in auto parts manufacturing and assembly processes.

Combing with the advanced self-developed optical technology and intelligent algorithms, Mech-Eye UHP-140 features micron-level accuracy. It can deliver outstandingly high-quality 3D images even for polished, shiny, and highly reflective parts.

It doesn’t matter when it comes to complex parts, material variation, glossy paint with high brightness, and reflective metal parts that may cause severe interferences for optical inspection performance. Mech-Eye UHP-140 can cope with the above challenges, expand the quality inspection & monitoring capacity, and help automotive and other industries achieve high-quality manufacturing.

01 – The All-New Self-Developed Image Fusion Algorithm That Effectively Reduces the Blind Spots and Delivers Much More Outstanding 3D Images

With the advanced image fusion algorithm, Mech-Eye UHP-140 can effectively fill the blind spots of the monocular camera and generate detailed and accurate point cloud data for parts even with subtle visual blind spots.

In inspection and measurement applications of the automotive industry, even the subtlest errors can affect the precision execution of assembly. Take round holes, the most common positioning holes in the body assembly, as an example. Round holes create chamfers during the machining process, and the chamfers on their edges are in the visual blind zone (the width usually ranges from 0.1 mm to 0.6 mm), which poses a challenge for traditional cameras to provide complete and clear images.

As shown in the figure, the point cloud data of round holes collected by Mech-Eye UHP-140, compared with that captured by the monocular camera, deliver complete and accurate 3D information of the slight chamfer in the visual blind zone with fine details.

02 – The Next-Generation Anti-Reflection 3D Reconstruction Algorithm to Avoid Missing or Defective Point Clouds of Complex-Shaped and Reflective Parts

For various highly reflective dented parts and metal parts that are easy to scatter light, the traditional algorithm can solve the problem of high surface brightness by adjusting the exposure parameters and capturing from multiple angles. But still, it is often difficult to find the right angle for complex-shaped and reflective parts to take clear images.

The Mech-Eye UHP-140, which adopts the advanced anti-reflection 3D reconstruction algorithm, can effectively suppress the interference caused by complex-shaped parts and strong reflections, guaranteeing high-quality point cloud data output. Mech-Eye UHP-140 can better handle complex parts, material variation, and other sophisticated situations in automotive inspection and measurement applications.


Advanced Optical Design for High Measurement Accuracy and Stable Imaging

After long-term field research at customer sites, Mech-Mind found that in typical applications of automotive and other industries, the accuracy of inspection and measurement is extremely demanding. Mech-Eye UHP-140, based on the advanced optical design, makes it all possible that its lens distortion is only 1/5 of the traditional lens, and its accuracy reaches 0.03 mm (refer to the German VDI/VDE 2634 Part II standard). The 2.6 μm point Z repeatability (σ) and the 0.09 μm region Z repeatability (σ) ensure Mech-Eye UHP-140 can output ultra-high precision inspection and measurement results with a fulfilling scanning speed and high-quality imaging that meet the actual demands.

04- Compact & Lightweight Design and Open Interface for Rapid Deployment of Various Inspection and Measurement Applications with High Flexibility

Mech-Eye UHP-140 is compact and lightweight, which can reduce the robot payload, and is suitable to be installed at the end of the robot arm to handle inspection and measurement problems in automotive parts manufacturing and assembly with high flexibility. Mech-Eye UHP-140 provides multi-language and multi-platform SDK options and an open interface for easier deployment. It integrates with Mech-Vision graphical machine vision software and Mech-Viz robot intelligent programming environment to easily and quickly deploy various inspection and measurement applications.

05 – Industrial-Grade 3D Camera That Better Meets Real-World Challenges

Mech-Eye UHP-140 adopts aluminum alloy housing with a fully enclosed design. It’s IP65 water and dust proof, and has passed CE, FCC, VCCI, and RoHS international certifications. Mech-Eye UHP-140 can cope with dust, vibration, humidity, electromagnetic interference, high temperature, and other harsh environments.
