只有在受到控制时，光才能达到所需的效果。车头灯就是一个很好的例子。借助现代光学技术，两个小小的 12 伏特光源即可照亮道路的特定部分。在生产车头灯时，必须特别注意以确保其造型完美。通过对产品进行长时间加热，可以减轻因为多个塑料部件连接在一起而引起的材料应力。CeraCon GmbH 是生产此类回火过程系统的专家。该公司成立于 2000 年，其产品范围包括用于减轻各种材料和组件应力的热系统。在 CeraCon 最新的车头灯回火设备中，Festo 元件以即可安装的完整解决方案发挥了辅助作用。该解决方案的亮点是五米高的垂直升降机。配备了新的 CMGA 安全系统，不仅能保证产品的快速运输，还能保护机器及其操作人员。
四层加热通道
在 CeraCon 的新型热系统中，在环境温度恒定保持在 266°F(130°C)的环境中，车头灯将在温暖的“浴缸”中经历时长一个小时的去应力流程。为了尽可能减少嵌入式系统的占用空间，CeraCon 根据自身成熟的组件开发了针对客户的多层水平系统。在四个垂直堆叠的区段中，组件载体在每个区段上都要通过一条长约 12 米的加热通道。使用升降机系统连接各个运输层，升降机系统负责在入口和出口点进行垂直升降。多层系统的占用空间仅为卧式系统的四分之一。每小时有 120 个组件通过热系统，循环时间为 30 秒。
When it comes to tempering car headlights in the new system, uniform heat distribution is of paramount importance. This depends not only on a sophisticated ventilation and heating system, but also on the smooth transport of component carriers. To guarantee these conditions, CeraCon uses type EGC toothed belt axes. They offer high speed and dynamic response. Specially developed profiles with an optimized cross section make the actuators torsion-resistant with a high load bearing capacity. The EGC variant used in this system, which extends to an impressive height of around four meters, transports the component carriers from one level to the next in the lift system. CeraCon and Festo had to come up with something very special, in order to create the complete system, with the CMXR controller and CMMP-AS and CMMS-AS motor controllers. CeraCon began by making the frame for subsequent installation in the system, which would also be used for the secure transport of the very long axis. Once delivered to Festo, it was equipped with the EGC toothed belt axis and all the wiring and tubing was fitted. Back at CeraCon, the turnkey system just had to be set up and adapted to the rest of the installation.
The toothed belt axes of the new thermal system are actuated using the CMXR multi-axis controller. The complete kinematic system solution combines a mechanical system with electric actuator and control technology into a complete motion control package, with integrated interfaces to all system components. Special features such as smooth position transitions considerably reduce travel times. Speed must not come at the expense of safety, however. This is ensured by the new Festo CMGA safety system, which guarantees the safe operating stop of the lift system. Employees can access the lift shaft without risk when carrying out maintenance work. CeraCon collaborated with experts from Festo to develop a new redundant brake system for the installation. The employees of both companies worked very closely together during all phases, from the joint risk assessment to technical implementation of the fully automatic and manually executable brake test.
Intensive co-operation is also the reason why CeraCon CTO Erich Krämer has been choosing Festo for many years: "Punctuality, reliability and competency are crucial factors in plant engineering. I have been working with Festo in a number of different areas of the industry over the last 25 years or so and I greatly value the engineering expertise of Festo employees." Both companies joined forces and worked together from the design stage to the commissioning phase. Together they developed a technologically advanced solution, which sets a new benchmark in the area of thermal systems. The new system provides Tier 1 suppliers with a high-performance inline solution for tempering car headlights that saves space and that guarantees the highest possible level of employee safety.
