The multi-level transportation seen in science fiction movies may become a reality in the near future. In early August , NEC Corporation of Japan flew a " flying car . " This drone-like machine, equipped with four propellers, hovered smoothly in the air for about a minute, reaching a height of 3 meters . It is expected to be operational in 2023 .
As one of the world's leading machine vision companies
Cognex cannot lift the car body off the ground,
But it can make car production and quality " take off ".
BMW Brilliance Automotive Ltd. (hereinafter referred to as BMW Brilliance) has built a world-class engine plant in Shenyang. Due to concerns about equipment quality, the new plant requires the addition of a vision system to identify the posture of parts.
BMW Brilliance requires this vision system to be able to identify whether the relative positions of the internal components of the engine are correct, in order to ensure that the engine assembled by the equipment performs normally.
Because Cognex is a long-term partner of BMW Brilliance,
Therefore, the new plant's visual inspection upgrade project specified the use of Cognex's vision system.
Cognex engineers who arrived at the scene to assist were testing the spring's posture.
The corresponding procedures were developed based on the specific objects being tested. (For details, please click " Read the original text " )
1. Check the presence, type (white and green), and location of the spring.
2. Check the presence and type of seats (large and small).
Cognex engineers stated, " Due to process and space limitations, only one set of cameras could be used. Furthermore, the 16 locations to be inspected could only be detected under specific engine conditions. Therefore, we adopted a solution where servo motors drive the cameras for individual inspections, which requires the cameras to have extremely high stability and accuracy. "
Thanks to Cognex's powerful vision system, the user-friendly In-Sight Explorer interface, and the fast and accurate reading of the DataMan barcode reader, coupled with suitable lighting, an exceptionally high pass rate was achieved. Brilliance BMW quickly implemented the collection and tracking of quality data for critical components, saving manpower, ensuring accuracy, and significantly increasing production speed! A production engineer from Brilliance BMW concluded, " With the ever-increasing demand for automobiles, both production volume and quality are crucial. Adopting Cognex's advanced vision system has solved both of these major problems simultaneously, while also reducing production costs. Cognex has provided invaluable value to the company and is a trustworthy partner. "
To summarize!
The reason why this cooperation with BMW Brilliance was successful is
This is mainly due to Cognex's two " magic weapons " :
1. PatMax image matching technology
PatMax , the industry gold standard for artifact and feature localization, provides accurate and repeatable detection under challenging conditions. This technique uses a series of boundary curves independent of pixel grids to acquire the geometry of an object, then searches for similar shapes within the image. This method is not limited by specific gray levels, thus accurately locating objects regardless of their angle, size, or shape.
2. VisionPro vision software
The powerful VisionPro vision software in the vision system fully supports the .NET language. Using the Visual C# programming environment , VisionPro vision tools can be quickly and flexibly applied to the system. High-speed image acquisition based on the PCI bus enables rapid product defect location during inspection, eliminating concerns about defective products being carried over to the next workstation. The QuickBuild settings in VisionPro vision software are simple and easy to learn, with clear and intuitive tool parameter adjustments. Even field personnel who are not frequently involved in vision systems can easily master the debugging process after a short training period.
