芬兰设备制造商 PKC Electronics 的自适应测试平台预示着电子设备测试的新纪元,直到现在仍主要以手动方式进行。随着诸如智能手机、平板电脑或具有触摸显示屏以及完善的音频或视频功能的导航设备之类的移动设备变得越来越复杂,对它们进行全面测试的任务也越来越复杂。用户界面性能测试、触摸屏滑动测试、移动设备侧面的按键和开关操作以及扬声器和麦克风测试需要大量保证质量的测试程序。
智能手机和平板电脑市场的快速扩展也将进一步提高对可靠测试设备的需求。仅 2013 年,全球使用的智能手机就达 14 亿部。平板电脑的数量从 2010 年的 1700 万台增加到了去年的 1.95 亿台。
“今天,对于我们来说,提供交钥匙测试设备非常重要,您所要做的就是快速更换适配器以适应不同的终端规格,并只需按一下按钮即可为测试程序检索正确的软件”,芬兰 PKC Electronics 测试解决方案业务区域经理 Kimmo Hyrynkangas 解释道。Hyrynkangas 继续说道:“许多最终用户平均每天需要更换适配器和相关程序两次。”
Elektrobit 运营经理 Marko Anttila 表示:“凭借 Chameleon 品牌,PKC Electronics 开发出了我们所需要的灵活测试设备。” Elektrobit 是芬兰的车辆移动设备和信息娱乐系统制造商。他补充说:“配备了相应的适配器后,该解决方案甚至可以对包括 10,000 至 100,000 个单元的中小型系列进行快速而可靠的测试。”
高度自动化:唯一的手动工作是定位移动设备。
测试设备的高度灵活性和适应性使客户能够应对移动设备种类繁多且产品寿命周期不断缩短的情况。开发时间一直在缩短。现在必须在开发阶段就进行大量的测试。理想情况下,测试系统应该能够在开发阶段和批量生产中使用。最终客户还需要在一个测试阶段中集成多个测试功能,以确保批量生产中的快速吞吐量。其中包括显示/触摸测试、性能测试、音频测试和射频测试以及全面的评估,例如对音频测试结果的全面集成分析。因此,Chameleon 系统为集成测试仪器设定了新标准,从而允许在单个紧凑平台上执行测试。
另一个行业趋势也即将出现:由于测试设备已集成到生产单元中,因此测试设备的尺寸必须越来越小。拥有足够的测试容量也很重要,这样测试过程才不会导致供应瓶颈。Hyrynkangas 解释说:“这是 Chameleon 系列测试设备与市场上其他产品的另一个不同之处——因为它们可以分析设备内的测试”。
“The mini planar surface gantry EXCM from Festo appeared on the market at exactly the right time”, says Risto Mäkelä, Chief Engineer at PKC Electronics. “With this compact, ready-to-install planar surface gantry, precise and fast positioning in tight installation conditions is now extremely easy.”
Jukka Merisalo, Key Account Manager at Festo Finland, adds: “The planar surface gantry EXCM really shows off its strengths in situations where every millimetre counts.” The compact planar surface gantry can travel to any position within its working space. It just needs an area equivalent to a DIN A4 sheet. The recirculating toothed belt moves the slide within a two-dimensional area (X- and Y-axes). The fixed motors are connected to the slide and thanks to the parallel-kinematic drive principle, the moving masses remain low. This allows fast positioning at speeds of up to 500 mm/s and repetition accuracies of the order of ±0.05 mm.
Together with the electric slide EGSL, the Z-axis is responsible for the correct functioning of the touch and swipe tests. The pneumatic slide DGSL is equipped with a microphone and light cube, allowing audio, camera and display tests to be performed.
The gantry is quick to commission and can be integrated quickly into machines. The pre-parameterised drive and controller package gives users the security of knowing that they can concentrate on their own core competencies without having to concern themselves with the details of automation technology. “The fact that Festo could offer us a complete package consisting of hardware, software and a consultancy service is what tipped the balance in their favour”, says Mäkelä.
