High\u2011Speed Automatic Magnetic Ring Current Test Bench<\/h1>\n

The current test bench for this type of apparatus utilizes high-speed automatic machinery to accurately detect and classify currents through magnetic rings (often referred to as toroidal cores) that are used in current transformers, device leakage protection devices, and sensors. This apparatus can achieve efficient mass production of through the implementation of completely automated processes from the feed and arrangement of wires to the test and sort of products prior to shipping; approximately 20,000 pieces can be completed with this apparatus in one 8-hour period.<\/p>\n

Using HIOKI\u2019s Leakage Current Tester, this workbench is designed to reliably measure and program a 15-50mA range of current values to automatically classify a product into 10 separate classes of current (9 qualified and 1 NG bin) then sort them into the correct bin locations. This automation greatly reduces the amount of manual handling required through material separation, wire positioning, and connection. The workstation was built using high-quality materials and components: Omron PLC\u2019s and sensors, AirTac cylinders, and Inovance motors to insure continued long-term performance. Its built-in OEE data storage system, and a simple to use HMI that operates in both Chinese and English, provides assistance to bilingual users.<\/p>\n

What is a Magnetic Ring Current Test Bench?<\/h2>\n

An automated test system is called a Magnetic Ring Current Test Bench. This test bench will measure leakage current and\/or sensitivity threshold for the magnetic rings (also known as toroidal cores) in Residual Current Devices (RCDs), Current Transformers and Magnetic Sensors. The test bench will automatically feed the magnetic rings, connect test leads, apply a programmable current (15\u201150mA) and measure the actual trigger current that caused the ring to be triggered. The system will sort the magnetic rings into up to 10 different current range bins (9 Pass Range + 1 Reject Bin) depending on the measured value. The purpose of this system is to ensure that only those rings with the proper current sensitivity value will be used in safety sensitive applications (such as RCCB & RCBO). There are many manufacturers producing high volume quantities of electrical component magnetic components and the use of this test bench is essential to them. In addition to our non\u2011standard; custom solution for the Magnetic Ring Test Bench, we can customize it to the customer’s requirements for the test current range, number of bins, and feeding system based on the customer’s ring size and production volume.<\/p>\n

Principaux avantages techniques<\/h2>\n
\n
\n

High throughput with minimal labor<\/h4>\n

The fully automated process (feeding, wire connection, testing, sorting) replaces 5\u20118 manual operators. At 20,000 pieces per shift, the bench pays for itself within 6\u20119 months in labor savings alone.\n <\/p><\/div>\n

\n

Precision HIOKI measurement<\/h4>\n

Integration with a HIOKI leakage current tester ensures measurement accuracy and repeatability. The system automatically adjusts the test current and records the exact trigger point, eliminating operator reading errors.\n <\/p><\/div>\n

\n

10\u2011bin intelligent sorting<\/h4>\n

Nine pass bins allow fine\u2011grading of magnetic rings by sensitivity (e.g., 15\u201118mA, 18\u201121mA, \u2026 up to 47\u201150mA). Tight\u2011tolerance applications (e.g., 30mA RCDs) benefit from this precision classification, reducing product rejects and improving final assembly yield.\n <\/p><\/div>\n

\n

OEE & production management<\/h4>\n

The built\u2011in OEE data storage system tracks shift output, test pass rates, bin distribution, and equipment downtime. The bilingual HMI provides real\u2011time dashboards, making it easy for operators and management to monitor performance.\n <\/p><\/div>\n<\/p><\/div>\n

Customer Success Story \u2013 Magnetic Component Manufacturer<\/h3>\n

A company that manufactures Toroidal Cores for RCCB was trying to increase their testing throughput and improve the accuracy of the classification process. They had a manual test set-up that had inconsistent contact resistance and only three current bins; therefore, they were doing rework. Benlong provided them with a magnetic ring current test bench along with a HIOKI tester and ten bin sorting. The results after three months were:<\/p>\n

\n
20,000 pcs\/shift<\/strong> Achieved (5x manual)<\/div>\n
99.5%<\/strong> Test consistency (Cpk \u22651.33)<\/div>\n
-80%<\/strong> Labor cost for testing<\/div>\n<\/p><\/div>\n

A significant RCD manufacturer was able to use precise, graded magnetic rings because the bench has already made up for its purchase with a return on investment in less than seven months.<\/p>\n<\/p><\/div>\n
