机器视觉

机器视觉

An integral part of manufacturing, vision systems are useful in many laser applications, including marking, drilling, etching and engraving. Over half of our custom laser systems incorporate some vision element—all with varying levels of complexity.

在最基本的层面上,Vision为激光过程提供了验证,指导和位置信息。当今的技术 - 加上我们的专业知识,使我们能够以更精致的方式整合愿景,以提高您的准确性,重复性和质量。

Pre-process: Identification and Guidance

Our vision systems identify and guide the laser’s function. The system retrieves a product’s data by scanning the attached travel documentation. Then, by quickly reading the barcode, it determines part identity, quantity, serial numbers and other process data. The vision system communicates this information to the laser’s control system so it can perform its function—all without manual intervention.

我们的视觉系统还将零件定位在集合中,以确保正确定位。如果没有,该系统将过程与零件位置对齐,以精确切割,钻或标记零件。这些数据还可以指导机器人拾取零件并将其放置在激光字段中。

Post-process: Validation

激光执行其功能后,您可能需要验证结果以确保质量和准确性。视觉系统以以下方式提供验证:

  • 通过/失败验证 - 系统验证标记,孔或焊缝的存在。
  • Dimension—the system ensures the dimensions and positioning of the mark, hole or weld are accurate.
  • 可读性 - 系统验证激光标记的文本和机器可读代码的可读性和内容。
  • 合规性 - Vision系统验证了根据ECC 200和ISO/IEC TR 29158(AIM DPM)标准的激光标记为2D矩阵的合规性。

Vision Systems in High-speed Manufacturing Lines

实时验证激光动作的能力对于高速制造线至关重要。使用我们的即时激光处理技术,我们的视觉系统在不停止的情况下在制造线路上移动时监视零件。

For药品片钻孔machines, pre-processing vision ensures each tablet has the right orientation for drilling. If not, the automated system uses the vision system’s feedback to return the tablet to the previous step. After drilling, the vision system detects any faults while the tablet is on the conveyor line. If a tablet doesn’t meet the right specifications, it’s removed from the line.

自动化,视觉和激光精度的这种组合使我们能够创建激光系统,每小时能准确钻140,000片药品。

Our Vision Capabilities

CMS Laser is a Cognex-Certified Vision Integrator. Our Vision Lab includes various Dataman and Insight cameras, as well as a full range of lenses and diode lights in different wavelengths. We combine this hardware with our extensive knowledge of Cognex software and vision algorithms to develop off-axis, robot and coaxial vision systems.

我们的工程师一直在将视觉系统开发和集成到激光机中已有二十多年了。我们利用此专业知识来设计适合您应用的完美激光系统 - 考虑以下内容:相机,lighting, 和optics

  • Off-axis direct view。当激光器执行其功能时,相机和激光向下指向。此设置适合输送机。
  • 离轴以一定的角度。当激光器向下指向时,相机坐在侧面并以一定角度坐在侧面,从而消除了激光和相机位置之间的运动需求。由于角度,软件使用透视校准纠正了扭曲的图像。
  • 轴上, orthrough the optics vision。We set up the camera system within the same lens as the laser. Though the field of view is small, this configuration is extremely fast and provides both high resolution and magnification.

Cameras

We work with a variety of cameras and determine the best fit based on resolution, process speeds, available algorithms—and more. High-resolution cameras (greater than 1 megapixel) are ideal for processing finer details and tight tolerances within a larger field of view. Low-resolution cameras (less than 1 megapixel) require less processing time and computing power. They’re ideal when speed or cost take priority over accuracy.

灯光

我们可以对视觉系统的照明功能进行编程,以在同一系统内具有多个配置。我们说明明亮和黑暗的田地,弥漫性与直接照明,背光,颜色以及更多。

Optics

We can set up our cameras in different ways depending on your application. Common configurations include: Off-axis direct view, off-axis at an angle, and on-axis, or through the optics vision configuration.

Vision System Options

离轴直接视图

当激光器执行其功能时,相机和激光向下指向。此设置适合输送机。

Gantry Laser Systems- 由于需要将相机放置两次,因此离轴配置会减慢处理速度。一旦进行部分位置和验证,其次是将激光放置在处理区域上。在这种情况下,通过光学视觉更快。

离轴以一定的角度

当激光器向下指向时,相机坐在侧面并以一定角度坐在侧面,从而消除了激光和相机位置之间的运动需求。由于角度,软件使用透视校准纠正了扭曲的图像。

Through the Optics

轴上或通过光学视觉是相机系统使用与激光器相同的镜头的地方。尽管视场很小,但此配置非常快,并且提供了高分辨率和放大倍率。相机能够利用Galvo镜子的扫描速度,以识别基准和其他地标,以定位处理区域。

3-D视觉功能

Though most configurations involve one camera and a two-dimensional space, we can add a third axis by using multiple cameras or a stereo vision system. This 3-D configuration informs the system of a part’s exact dimensions—increasing the accuracy of part sorting processes. After a part is lased, 3-D vision systems can also validate the depth of an etch, engraving or hole.

软件Controls

我们的软件功能将照相机,照明和光学元件融合在一起,以增强激光系统的灵活性和多功能性。例如,我们可以对软件进行编程以控制同一系统中的多个照明配置和功能,从而使您的激光系统处理不同的零件。该软件还优化了视觉识别,验证和验证过程,包括模式查找,图像增强,1-D条形码或2-D矩阵数据读数,二进制和文本数据验证。
