Detection method and detection system for ink-jet printing omission of ink-jet printer

The invention relates to a detection method and detection system for ink-jet printing omission of an ink-jet printer. The method comprises the steps that the ink-jet printer is detected when a part to be subjected to ink-jet printing passes through the ink-jet printer; and when it is detected that the ink-jet printer omits ink-jet printing, an alarm is given out, and meanwhile a conveying chain for conveying the part to be subjected to ink-jet printing is stopped. According to the detection method and the detection system, an alarm is given to remind a worker of coming over for processing, and after processing is completed, the conveying chain is restarted through a reset button; and a false alarm can be timely given out when the ink-jet printing is abnormal, so that products with ink-jet printing omission can be effectively prevented from flowing into the market. 本发明涉及一种喷码机无喷码检测方法及检测系统，所述方法包括：当检测出有待喷码件经过喷码机时，对所述喷码机进行检测；当检测出所述喷码机无喷码时，发出警报，同时停止运输所述待喷码件的输送链条。通过发出警报提醒工作人员过来处理，在处理完成后，通过复位按钮重新启动输送链条。由于能够在出现喷码异常时，及
