BeamWatch® 集成

BeamWatch Integrated是一种全自动激光测量系统，设计用于对工业生产线上的关键激光束参数测量进行整合。BeamWatch Integrated基于BeamWatch专利的非接触式仿形原理，可实时提供所有关键激光束参数的非接触式同步测量，同时其内置功率计可传输绝对功率读数。

  • 测量功率不超过10 kW（根据要求可达30 kW）的聚焦光束的所有关键激光束参数 实测激光参数包括：
    • 光束腰（焦点）的宽度和位置
    • 焦点转移
    • 质心
    • M2 或 K
    • 发散
    • 光束参数产品
    • 瑞利长度
    • 光束倾斜角度
    • 绝对功率
  • 全自动操作
  • 利用良好/不良信号进行趋势分析
  • 带时间轴的详细报告
  • 适用于不同类型的焊头，无需更改测量系统
  • Industrial interface of choice in addition to GigE: PROFINET, EtherNet/IP and CC-Link
  • 坚固耐用，适合工业生产环境
  • 漂移操作期间进行频繁测量的简短测量时间
  • Two options for single-mode or multi-mode lasers available

BeamWatch Integrated具有百叶窗加固设计，是一种小巧而独立的系统，可以容纳不同类型的焊头。各种接口能够将系统集成到生产网络和自动化生产线中，以便于直接传输测量数据。较短的测量时间能够在装载/卸载阶段自动检查激光束，频率为每个生产单元检查一次。此外，可利用标准接口读取所有参数，并可根据需要，对每个单独的组件进行一致记录（作为过程监控的一部分）。准确的趋势图基于大量测量数据，可以为预测性维护提供有用的观点。可以为实测参数设置公差和极限值，以便根据需要触发校正操作。由于非接触式测量不会对仪器造成任何磨损，因此BeamWatch Integrated几乎无需维护即可操作。

Although ever more powerful cutting and welding laser equipment is being used on modern production lines, all too frequently – due either to lack of time or to the complexity – the quality of the laser beam goes unchecked during the production process. Because laser process quality is directly linked to laser quality, this can lead to large batches of defective parts in high-throughput production lines, e.g. in the automotive industry. In addition to the significantly higher risk of loss or safety issues, neglecting to monitor the quality of the laser beam consistently makes it almost impossible to detect the root cause of problems, when they occur.
 
To address this issue, BeamWatch Integrated was developed. Based on the patented non-contact BeamWatch measurement principle (using Rayleigh scattering), this technology provides for the simultaneous measurements of multiple profiles along the beam caustic at video rates, delivering – in mere fractions of a second – all the beam key parameters according to ISO 13694 and ISO 11146 standards. Real-time performance also allows for detection of dynamic focal shift, while a NIST-traceable power sensor assures absolute power readings. With its shutter and rugged design, BeamWatch Integrated is a compact and self-contained system that can accommodate different types of welding heads. A variety of interfaces makes it possible to integrate the system into production networks and automated manufacturing lines to facilitate direct transfer of measurement data.
 
The short measurement times allow the laser beam to be checked automatically during the loading / unloading phase, as frequently as once every produced unit. Additionally, all parameters can be read out using standard interfaces and – as part of the process monitoring – consistently documented for each individual component, as desired. Since they are based on a large amount of measurement data, trend diagrams are highly accurate and can therefore deliver useful insights for predictive maintenance.
 
Tolerances and limit values can be set up for measured parameters to trigger corrective actions as needed. BeamWatch Integrated operates virtually without maintenance, because contactless measurement exerts no wear on the instrument.

(1) For circular beam centered within ¼ of beam diameter. IMPROPERLY CENTERED BEAM CAN CAUSE DAMAGE TO SENSOR. Maximum tilt angle on power sensor ±5 degrees. For rectangular beam please consult MKS Ophir representative
(2) Water temperature rate of change <1ºC/min. The recommended flow rate can be lowered proportionately at lower than full power but should not be below 3 liter/min. The response time will be optimum with the recommended flow rate.

    The system can be manually operated by PC using BeamWatch, our full-function software with an extensive set of ISO quantitative propagation measurements, NIST calibrated power measurements, graphical representations of the beam caustic. Requires user supplied PC.
     
    The system can alternatively be operated automatically by PLC using PROFINET, EtherNet/IP or CC-Link. Tolerances and limit values can be set-up for desired measured parameters to trigger corrective actions. The trend charts give insights for early problem detection and predictive maintenance.
     
    In both cases PDF and CSV reports can be generated.
