PCB自动对位装置的工作原理如下：
PCB板通过输送机构被送至放置组件上方，当被一个X向对位块形成的挡料块挡住后，升降机构驱动输送机构下沉并将PCB板放置在放置组件的放置平面上；
两个Y向对位板、两个X向对位块均向PCB板移动，当两个Y向对位板、两个X向对位块都和PCB板接触后就完成了PCB板的初定位；
检测定位机构启动，通过获取PCB板上的标记点的位置计算出PCB板的初始坐标值和放置组件所在的坐标系的原点(即预设坐标值)差异值；
通过移动旋转结构将PCB板移动至预设坐标值，即完成PCB板的自动对位；
完成自动对位的PCB板被机械手送向打印位置打印，同时下一张PCB板被送入PCB自动对位装置继续进行自动对位。
上述PCB自动对位装置可以全部实现自动化，从将PCB板送入自动对位装置到完成对位送向喷墨打印位置通过PLC或软件等方式控制可在3～5秒内完成，这个时间大大少于PCB板的喷墨打印时间。因此，在上一张PCB板打印时完全可以完成PCB板的自动对位，进而实现了PCB板不间断打印的自动化生产，从而大大提高了工作效率，降低了生产成本。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
