IONIQ 20 – 泄漏测试仪
电池测试
ATEQ 在生产线质量控制测试仪这一成熟理念的基础上，针对大批量生产塑料件的特殊要求，开发了一种新型泄漏测试仪。仪器用于检测局部成型故障、膜厚度不足、穿孔等。事实证明，该仪器在测试袋装电池芯方面也很有效。
IONIQ 以放电电流测量为基础，能够检测出 10 微米以下的缺陷。
IONIQ 20 : 应用
电池袋电池、塑料瓶盖、塑料包装..
IONIQ 20 : 测试原理
• The IONIQ measures the current flowing between a patented charged probe and a ground plate placed under the part to be tested.
• The IONIQ uses the % of the nominal voltage (which reflects the discharge current), measured on the part as PASS/FAIL level.
• In a PASS situation (fig 1) : No hole, no weak part, the IONIQ measures a high %. The measured voltage and the nominal voltage are virtually equal. The result is above the reject level, the part has passed the test.
• In a FAIL situation (fig 2) : The IONIQ measures a low %. The measured voltage is significantly below the nominal voltage. The result is below the reject level, the part has failed the test.
• Test limitations: short probe-part-plate distance, electrical insulation from environment.
IONIQ 20 : 特点
• Integrated ionising high voltage generator (5 to 27.3 kV)
• Reject levels as % of nominal voltage (0 to 100%)
• Monitoring and protection of high voltage generator
• Limitation of the current rating
• Speed: Minimum cycle time 0.6s
• I/O’s for instrument control and results
• 32 programs
• Remote control allows the test module to be closed to the test part
• And: Language selection, customization of test …

IONIQ20 : 技术
A high voltage loaded sharp end is applied next to an earth connected base and in between lays the plastic part we test. Should a hole exist in the part, ions will start moving from the earth to the sharp end. This will result in a loss of power and be translated into a leak.
While this method does not quantify the leak rate in terms of cc/min for example, it is the fastest ever invented to detect a leak in a go / no go process.
We have achieved cycle times of less than 7/10 of a second.
