is a manufacturer of residential wood stoves. Te company faces seasonal customer demand patterns and produces eight series of wood stoves, each with four variants. Two of the series have special coating processes after the individual assembly parts are cast, with special handling requirements. Te metalcaster implemented a test automation cell between the cleaning and sorting processes as a potential test area for implementing a flexible automation solution for han- dling the varying part families. Te company wanted to test an automation cell built around the range of products that they manufacture and choose the best way to integrate it into production. Te company incorporated a used robot to implement cost effective, quick changeovers for fast, flexible part routing and handling. Te overall design concept of the material handling’s


Ethernet communication handling system consisted of three subsystems: the robot manipulator, the material handling system and the vision system. In the cell, an overhead camera identified the orientation of the part lying on the conveyor belt, which was internally tracked by the robot (Fig. 1). Te


产,火炉有8个系列,每个系列有4个款式。在单个 组装部件铸造完成后,其中的两个系列需要完成特 殊的涂层工艺,有特殊的处理要求。该铸造企业在 清理和分拣工序中间设置了自动检测单元,作为关 键的测试区域,实现柔性的自动化解决方案以适应 不同的产品系列。公司希望自动化测试单元能够覆 盖全系列产品范围,选择最好的方式将其集成到生 产中。公司将一台旧机器人集成到生产中,实现成 本高效和快速切换,使铸件的运输和分拣更加快速 灵活。


材料运输的以太网通讯处理系统的总体设计理念 包括3个子系统:机械手、材料转运系统和视觉系 统。在单元中,摄影机可识别铸件在传送带上的位 置,由机器人内部跟踪(图1)。摄像机捕捉到的图 像由视觉系统进行处理,并通过闭环网络连接传输
