Overview
The Qinji GO-1 Dual-Drum Free-Fall Impact Tester is an electromechanical test system engineered for standardized repetitive free-fall impact evaluation of small electronic consumer devices and electrical accessories. It operates on the principle of controlled rotational drum motion, where specimens—such as mobile phones, Bluetooth earbuds, power banks, USB chargers, calculators, and plug/socket assemblies—are placed inside two independent cylindrical drums. As each drum rotates at a fixed angular velocity (5 rpm), gravity induces a predictable free-fall trajectory upon reaching the top dead center, resulting in two discrete impacts per full revolution. This replicates real-world user-handling conditions involving repeated accidental drops from defined heights (500 mm or 1000 mm), enabling quantitative assessment of mechanical robustness, housing integrity, internal component retention, and structural fatigue resistance under cyclic impact loading.
Key Features
- Dual independent drum configuration enables parallel testing of identical or dissimilar specimens—reducing total test cycle time and improving throughput consistency.
- Precisely calibrated drop height selection (500 mm and 1000 mm) ensures strict adherence to international test protocols without manual repositioning.
- Fixed-speed rotation drive (5 rpm) via industrial-grade reduction motor guarantees repeatable kinematic input; optional variable-speed motor upgrade supports customized impact frequency tuning (5–15 impacts/min).
- Transparent polycarbonate safety cover with interlocked mechanical switch halts operation immediately upon lid opening—meeting IEC 61000-4-2 and ISO 13857 safety requirements for operator protection.
- Robust steel frame construction and vibration-damped base minimize energy loss during impact transmission, preserving test fidelity across extended cycles.
- Integrated 6-digit mechanical counter provides tamper-resistant, non-volatile impact tallying—essential for audit-ready documentation in GLP/GMP environments.
Sample Compatibility & Compliance
The GO-1 accommodates specimens up to 200 mm × 120 mm × 60 mm per drum chamber, with mass range from 20 g to 1.2 kg. It is validated for use with plug-and-socket systems (including non-grounded plugs per IEC 60884-1), portable electronics housings, battery packs, and compact power adapters. The tester fully satisfies the mechanical execution requirements of multiple harmonized standards: GB/T 2423.8 (Ed: Free Fall), GB 2099.1–2008 (Electrical Accessories – General Requirements), IEC 60068-2-32 (Environmental Testing – Part 2-32: Test Ed: Free Fall), IEC 60884-1:2021, and EN 50075:1990 (Domestic Plug and Socket Outlets). All operational parameters—including drop height tolerance (±5 mm), impact count repeatability (±1 impact per 100 cycles), and drum surface hardness (≥60 HRC)—are traceable to national metrological verification procedures.
Software & Data Management
The GO-1 operates via hardware-based push-button control and does not include embedded software or digital data logging. However, its design supports integration into laboratory information management systems (LIMS) through external signal interfaces (e.g., TTL pulse output per impact event, optional relay module). For regulated environments requiring electronic records, users may pair the unit with third-party data acquisition systems compliant with FDA 21 CFR Part 11—enabling secure user authentication, audit trail generation, and electronic signature capture. Calibration certificates, maintenance logs, and test reports remain manually documented per ISO/IEC 17025 clause 7.7, with all mechanical counters certified annually by accredited metrology labs.
Applications
- Evaluation of plastic housing crack propagation and latch retention after repeated low-energy impacts.
- Verification of solder joint integrity in PCB-mounted connectors subjected to shock-induced inertial loading.
- Comparative durability screening of competing designs during NPI (New Product Introduction) phases.
- Quality assurance testing for OEM suppliers delivering components to Tier-1 electronics manufacturers.
- Conformance validation for CE marking submissions under the Low Voltage Directive (2014/35/EU) and RoHS compliance documentation.
- Internal R&D stress testing to establish failure mode thresholds prior to accelerated life testing (ALT).
FAQ
What standards does the GO-1 directly support?
The GO-1 is mechanically configured to execute test sequences defined in GB/T 2423.8, IEC 60068-2-32, GB 2099.1–2008, IEC 60884-1, and EN 50075. Its physical drop height, drum geometry, and impact count resolution align with these documents’ procedural specifications.
Is calibration service available?
Yes—Qinji provides annual recalibration services traceable to CNAS-accredited laboratories, including dimensional verification of drop height, rotational speed measurement, and counter accuracy validation.
Can the unit be modified for non-standard drop profiles?
Structural modifications are not supported due to certification constraints; however, custom fixtures (e.g., specimen cradles, orientation guides) can be designed and validated per customer-specified test plans.
What maintenance is required?
Routine inspection includes lubrication of gearmotor bearings every 500 operating hours, visual check of drum weld integrity, and verification of safety interlock function prior to each test session.
