IEC\/UL \u00b7 High\u2011speed sorting<\/div>\n

Ultra\u2011High Speed MCB Automated Testing & Sorting Line<\/h1>\n

Customer pain points:<\/strong> Because manual testing is very slow in high-volume production, operators may miss defects due to lack of proper test data traceability\/analysis. Changeover time to different MCB types can take hours, resulting in expensive downtime. The MCB automatic testing line addresses these issues with millisecond sorting, multi-station parallel testing, and full data traceability to allow manufacturers to achieve 100% IEC\/UL compliance and reduce rework by more than 80%.<\/p>\n

Use of high-speed indexing tables and robotic loading\/unloading provides non-stop operation. At the same time, tests (trip time (B\/C\/D curves), thermal magnetic calibration, and contact resistance) can be done, critical tolerances can be verified using high-resolution vision, and an ultra-stable sorting mechanism will separate Pass, Fail, and Rework products. The data acquisition system (DAS) logs all tests variables to maintain complete traceability. The transition times between different pole (1P-4P) and current ratings are measured in minutes rather than hours. The average production of the machine(s) reaches 1,800-2,400 units\/hour.<\/p>\n

What Problems Does an MCB Automatic Testing Line Solve?<\/h2>\n

MCB manual testing creates 3 significant problems: inconsistent quality (human error causes trip time to vary), limited production volume (60-80 units tested\/hour \u2013 1000s tested\/hour for automation), and no traceability (paper log cannot be audited). The MCB automated testing line removes all 3 of these barriers. The line automates the loading, testing, sorting and logging of data. For MCB manufacturers, this means: increased OEE; reduced cost of rework, and auditable data for IEC\/UL certification. The automated testing lines also resolve the issues of switching between testing
\nmethods (1P\/2P\/3P\/4P) or changing current ratings with a changeover time of less than 30 minutes once programmed into HMI (according to recipe).<\/p>\n

\n
\n Eliminates testing bottlenecks<\/strong><\/p>\n

The use of multi-station parallel testing (instantaneous trip, thermal calibration and contact resistance) allows the testing of one unit to reduce testing times from 60 sec\/manual to less than 3 sec\/unit.<\/p>\n<\/p><\/div>\n

\n Provides full data traceability<\/strong><\/p>\n

All tests results (trip time, calibration value, pass\/fail) will be stamped with time and serial no. Ensures ISO 9001; IEC audit compliance.<\/p>\n<\/p><\/div>\n

\n Enables rapid model changeover<\/strong><\/p>\n

Switching between different MCB types can take less than 30 minutes via recipe-based parameter switching, whereas manual recalibration can take hours.<\/p>\n<\/p><\/div>\n

\n Reduces field returns<\/strong><\/p>\n

Manually sampling does not catch all defects; however, by inspecting all items, many defects that would otherwise be missed will be captured. As a result, field failure rates may be reduced as much as 70%.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n

Core Customer Benefits \u2013 Why Manufacturers Choose This Line<\/h2>\n
\n
\n

Benefit 1: 25\u00d7 higher throughput<\/h4>\n

Manual Testers are able to do 60-80 units per hour. Using this line a tester can handle 1,800-2400 units per hour. This results in a 25-30x increase in productivity to meet maximum demand without needing to add shifts or employ additional test personnel and typically achieve a return on investment (ROI) in less than nine months.<\/p>\n<\/p><\/div>\n

\n

Benefit 2: Zero operator\u2011induced variation<\/h4>\n

Testers exhibit variability in their results due to factors such as time of day, fatigue, etc. In contrast, the automated process achieves much higher precision (\u00b11 ms) than human testers as a result of utilizing high precision sensors on the test line (\u00b10.5%), thus avoiding false passes and false failures.<\/p>\n<\/p><\/div>\n

\n

Benefit 3: Complete audit\u2011ready traceability<\/h4>\n

The trip time, calibration values, contact resistance and visible results of every unit have been recorded with a date\/time stamp and serial number. Export to a paperless report for IEC\/UL audits, instead of searching through paper logs for your information.<\/p>\n<\/p><\/div>\n

\n

Benefit 4: Fast changeover for mixed production<\/h4>\n

Change from single-phase, 10-amp, B type circuit breaker to three-phase, 63-amp, C type circuit breaker in under thirty (30) minutes. HMI loads new recipes; automatically adjusts test currents and time windows. No changes to mechanical components needed for most parameters.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
