中文摘要	本发明涉及一种食品、医疗用品等需完全密封包装的物品的针孔检测方法。将由绝缘材料包装包裹的导电物放置在一对检测电极的正下方；一检测电极通过导线与高压电源的正极相连，另一检测电极通过导线接入电流检测装置后接地；两检测电极水平摆放，相互间隔一定距离，该距离能够防止两电极由于高压击穿空气而导致短路；两电极的不锈钢珠链与密封包装物的绝缘材料包装表面接触；高压电源通过检测电极对密封包装物施加高压电，使密封包装物充电；针孔检测；交换两检测电极的极性，针孔检测。本发明能够实现对密封包装产品的高速在线无损针孔检测，可以检测出直径小于0.5μm的微小针孔，精度极高。

英文摘要	The invention relates to a pinhole detection method for articles which need to be packaged in a sealed mode in food, medical supplies and the like. Conductive materials which are packaged and wrapped by insulation materials are placed under a pair of detection electrodes one detection electrode is connected with a positive pole of a high-voltage power supply through guide wires, and the other detection electrode is accessed to a current detection device and then is accessed to ground through the guide wires the two detection electrodes are placed horizontally, and are spaced to each other in a certain distance, and the distance can prevent the two electrodes from being a short circuit caused by high-voltage breakdown air stainless steel bead chains of the two electrodes contact the packaging surface of the insulation materials of a sealed package the high-voltage power supply imposes high-voltage electricity on the sealed package through the detection electrodes, and therefore the sealed package is charged pinhole detection is conducted and polarity of the two detection electrodes is exchanged, and then the pinhole detection is conducted. The pinhole detection method for the sealed package is capable of achieving high-speed online lossless pinhole detection to sealed packaging products, and therefore small pinholes with a diameter of less than 0.5 micrometer are detected, and accuracy is high.
