本发明申请中其核心技术点之一在于对手机工位的划分，公知的，现有的常规手段是将手机测序项目单独一一测试，耗时长、流程节点多、监管困难，本发明申请采用与现有常规技术手段完全不同的设计思路，将手机的测试项目进行归类划分，由多个不同的测序项目共同构成一个大的测试项目，一个大的测试项目为一个测试工位，所有测序项目分类为四个大的测试项目，大的测试项目之间相互不影响，并行测试。
该手机多工位并行测试系统主要包括由传感器和执行机构组成的测试工位，所述测试工位有多个并用于测试不同项目，所有测试工位构成闭环的流水线，用于完成对手机的测试。
对于手机性能的相关测试包括对手机进行GPS、蓝牙、WIFI、触摸屏、背光、重力感应、接近开关、光感传感器、摄像头、LCD屏幕、听筒、话筒、扬声器、手机外放、充电、USB接口、耳机插口、按键等相关功能、性能和应用的测试，这些手机测试属于已有技术，本发明所述手机相关功能包括现有针对手机进行的各种测试，也包括可能新出现的其他测试。本发明各测试工位包含的测试单元可进行不同的组合。
主控系统，接收测试信息及控制系统传感器和执行机构。主控系统发送测试指令，接收手机反馈信息，接收各类传感器数据，控制电气执行机构和机械手。
下面以四个测试工位构成的系统为例。
系统传感器和执行机构又包括电气执行机构、机械手、多种传感器，由此类硬件构成四个用于测试不同项目的测试工位，用于完成对手机的整
个测试过程；四部手机同时放置在一个载具的不同方位，分别与四个测试工位一一对应，手机测试项目的切换，通过载具旋转带动手机移动至下一测试工位实现。为了方便描述，本实施例中将四个测试工位分别命名为第一测试工位、第二测试工位、第三测试工位和第四测试工位，其中，定义第一测试工位为首个测试工位，第四个测试工位为末端测试工位，一部手机完成整个测试过程需要依次通过第一测试工位、第二测试工位、第三测试工位和第四测试工位的测试，与此同时，四个测试工位实质上同时对四部手机进行不同的项目测试，通过分时复用，在同一个测试周期内对四部手机不同测试项目进行并行测试，由此提升测试效率。
如图所示，四个测试工位的结构和功能分别如下：第一测试工位位于舱门的内侧，且还用于完成手机的取放。第二测试工位由末端设置有多个触摸屏手指的机械手、USB插拔气缸、耳机插拔气缸以及手机前摄像头拍照光源组成；其中，USB插拔气缸带动USB数据线与手机连接，耳机插拔气缸带动耳机与手机连接；手机前摄像头拍照光源为手机拍照提供照明。机械手优选为三自由度机械手，可在XYZ在个方向进行直线运动。Z方向由升降台实现，XY方向由两个直线运动机构实现。当中央旋转机构旋转时，升降台处于抬起状态；中央旋转机构停下后，升降台下降，机械手可在XY两个方向运动，进行手机触摸屏的测试。
第三测试工位包括一个人工嘴、两个人工耳和一个手机后摄像头拍照光源；所述人工嘴用于模拟语音通话，位于手机麦克风的正上方；其中一个所述人工耳位于手机听筒下方，另一个所述人工耳位于手机外放下方，
用于捕获手机发出的音频信号和振动信号，完成对手机音频和振动马达性能的测试；所述手机后摄像头拍照光源为手机拍照提供照明。
第四测试工位由一个位于手机屏幕上方的工业相机、一个手机前摄像头预览照明光源和一个手机后摄像头预览照明光源组成。相机拍摄手机屏幕显示的颜色和图案信息，传送到设备主机进行分析，实现对手机屏幕、前后摄像头成像的测试工作。
四部手机在同一个手机载具的不同方向上，同时，通过中央旋转机构实现在不同测试工位之间的切换，四个测试工位所采用的测试硬件均采用现有成熟技术，故在此不作赘述。
上述测试工位的划分，是经过本发明申请的发明人创造性劳动得出的，根据每个测试项目所应用的硬件、时间、是否影响进行的最终确定，相对于现有的常规技术手段而言，本发明申请中的测试工位的归类划分具备突出的实质性特点和显著的进步。
主控系统包括有以下单元：语音分析单元，用于手机音频、振动测试；图像识别单元，用于手机屏幕，摄像头测试；手机通讯单元，用于手机WIFI、GPS、蓝牙测试；机械手控制单元，用于手机案件、触摸屏测试；I/O口交互单元，用于测试用户输入、输出结果；任务管理单元，用于协调四个测试工位上的手机并行测试。每个单元与对应的测试工位协作完成手机的测试。其中，语音分析单元主要对应硬件：人工耳、人工嘴、音频采集卡；图像识别单元对应硬件：工业相机；机械手控制单元对应硬件：机械手；I/O交互单元对应各I/O端口。
任务管理单元主要用于控制手机在不同测试工位之间的切换，假设四个测试工位呈360°均匀分布在手机的载具四周，则任务管理单元控制载具旋转的角度为90°，由此实现当前测试工位上的手机在旋转后，恰好进入下一测试工位中，完成连续的测试。需要说明的是，主控系统中的各单元均可以选用现有成熟技术实现，故在此不作赘述。

(22)位于第二测试工位上的手机为完成了第一测试工位上测试项目的手机，其在第二测试工位上完成触摸屏等项目的测试；
(23)位于第三测试工位上的手机为完成了第一测试工位和第二测试工位上测试项目的手机，其在第三测试工位上完成手机音频、振动测试；
(24)位于第四测试工位上的手机为完成了第一测试工位、第二测试工位和第三测试工位上测试项目的手机，其在第四测试工位上完成手机摄
像头、屏幕成像等测试。
一部手机先后经过第一测试工位、第二测试工位、第三测试工位和第四测试工位后，完成完整的测试过程，在下一个测试周期开始后，第四测试工位上的手机转动至第一测试工位，取出。
应当说明的是，本实施例以四个测试工位为基础进行阐述的，本领域技术人员在本发明的设计原理的基础上，若手机测试项目扩展超过本发明申请所测试的项目，则可以再增加并行的测试工位，如：五个、六个、七个甚至更多，以此实现多工位的同时工作；反之，若手机测试项目缩减而少于本发明申请所测试项目，则可以相应的减少测试工位；但是，需要注意的是，上述的改变均应当属于本发明申请的同一个发明构思。
