    Offline-Path Correction

    Many processing tasks require a robot path that is individually adjusted to the piece. Not only the position of the workpiece, but each individual processing point on the workpiece must be measured and the robot path correspondingly corrected. The VMT BK system measures the geometry and the position of the seam/joint/edge with an accuracy of 0.1 mm or better and corrects every individual support point of the robot path. The robot can thus carry out its processing tasks with the highest accuracy.

  • Gap Gauging

  • Gap measuring using the VMT dual head laser sensor

    由于如今的设计规格非常苛刻，汽车工程行业的设计规格和相关的建筑选择，差距变化和安装车身部件的冲洗效果已成为更重要的质量功能。

    Traditionally, such gaps and flush fit dimensions are measured in special “gap measuring tunnels”. These tunnels are equipped with a large number of sensors, because each measuring point requires its own sensor unit.

    因为这个原因increas传感器单元的数量es very quickly, especially when several, diverse car models are produced in a single production line. As a result, operation and maintenance become very complex, and the acquisition of such a solution requires a very large investment. And when such a solution has been selected, a change in models means a considerable input in regard to adjustments or extensions.

    By using the VMT dual head laser sensor a very high degree of flexibility is achieved, which permits a smooth and easy gap and flush fit inspection without any major effort, even on the most diverse car models. A simultaneous inspection of the gap width as well as the flush fit between the mounted parts can be performed on the body-in-white as well as on completed, painted cars in the final assembly stage.

    间隙测量的灵活性是通过通过工业机器人的双头激光传感器的精确定位来实现的。这样可以确保在没有任何重大安装工作的情况下，在汽车车身上的测量点进行个人选择。当然，这也适用于在以后阶段添加的点。

    In addition to the savings owing to reduced measuring technology, the resulting reduced space requirement - depending on the version - contributes to the efficient deployment of this VMT solution.

    The gap measuring cell can be realised in fixed cycle mode as well as in continuous mode.

    用激光测量的3D位置识别

    Partial solutions exist using classical sensor technology (inductive or ultrasonic sensors) or with the initial stages of image processing.

    However a lot of systems have failed in the face of the complex requirements and problematic site conditions. Thus the challenge for VMT consisted of finding a concept that unites the advantages of the individual sensor technologies specifically for each application.
    • VMT IS系统可以将非常不同的传感器或传感器系统组合在一起，并通过可靠的评估程序提取必要的信息，从而可以提供可靠的系统，从而确保最高的可用性。

      The system is based on 3D evaluation by means of camera technology and/or a height image for the controlling the robot grippers generated by measuring the runtime of the light. However a minimum organization of parts to be recognized and detailed, individual case studies remain absolutely necessary, if the high requirements for the installations availability and profitability are to be ensured.

      从容器或托盘以及零件和各种束的处理中进行托盘和拆卸物品的要求非常复杂。
    • The substantial challenges of these tasks are:
      • 项目复杂性和可变性
      • The very different surfaces of the objects to be processed
      • 识别容器，中间层（如果适用）以及异物和破坏性轮廓
      • 排除外部光线干扰
      为了满足所有对无故障操作和流程稳定系统的要求，VMT还决定了使用激光截面和激光飞行时间传感器技术的验证图像处理系统。
    • This kind of sensor technology provides not only significant freedom from external light interference for the testing process but also the requisite speed, and fulfills the requirements for accuracy. Additional information is also available for determining, for example, the stack height and recognizing foreign objects; this is often not available when using traditional image processing.

      VMT系统提供了将最合适的传感器链接到VMT软件的各种需求的能力，以便为问题生成最佳解决方案。除了图像处理扇区（通常是表面和线相机）外，它还涵盖了三角测量和激光灯截面传感器以及激光飞行时间传感器以及最新一代的超声传感器技术。
