Professional Projection Light EOL Testing Solutions
Reliable Mechanical Design Supports 24-Hour Uninterrupted Mass Production of Projection Lamps
Automotive lighting production lines generally adopt three-shift 24-hour operation mode, which puts forward high requirements on mechanical stability of EOL testing equipment. HY projector lamp EOL tester adopts thickened aluminum alloy frame and precision linear guide transmission structure, with anti-vibration pads at the bottom to weaken vibration interference during long-term continuous operation. All moving parts select imported wear-resistant bearings to extend service life of vulnerable components and reduce daily maintenance workload.
Every finished machine undergoes 72-hour full-load aging test before delivery, simulating three-shift mass production working conditions to screen potential mechanical faults in advance. The locking structure of quick-change fixtures adopts self-locking design to avoid positioning deviation caused by long-term repeated clamping. After serving over 50 auto lamp manufacturers for years, our equipment average failure-free operation interval exceeds 12 months, greatly cutting production line downtime losses caused by equipment breakdown compared with cheap small-brand test machines.

Why HY Projector Lamp EOL Tester Becomes Standard Equipment for Auto Lighting Factories
Now major vehicle brands raise stricter standards for automotive projection lamp pattern, luminance and electrical performance, and traditional manual visual inspection can hardly capture tiny pattern distortion and chromatic aberration defects. HY self-developed projector lamp EOL inspection machine integrates complete electrical and optical testing modules, finishing full-item detection within 7 seconds per product. The quick-replace fixture greatly cuts model switching time without repeated calibration, helping auto parts factories solve mixed production inspection pain points and effectively reduce finished defective outflow rate.
Different from single-function test benches on the market, HY reserves complete MES system docking interfaces to realize automatic data upload and one-to-one serial number binding, which matches the digital transformation demand of modern intelligent workshops. Our R&D team optimizes sealed optical darkroom structure to eliminate ambient light interference, so test data remains stable day and night. Every machine undergoes 72-hour full-load aging before delivery to support 24-hour three-shift continuous operation. For medium and large auto lamp manufacturers, one HY EOL tester can replace 3–4 manual inspectors, cutting long-term labor costs and lifting overall production line inspection efficiency significantly.
Quick-Change Fixture Customization Solves Multi-Model Projection Lamp Mixed Production Troubles
Most auto supporting factories arrange mixed production of 6–12 types of projection lamps on one single assembly line, and fixed jigs of old testing machines need long disassembly and calibration when switching models, severely limiting production turnover efficiency. HY designs modular quick-switch fixture system for projector lamp EOL tester, realizing model replacement within 2 minutes without professional technical staff operation, fully adapting to frequent product replacement in mass automotive lighting production.
We provide one-stop customization service covering fixture CNC processing, software detection parameter editing and MES secondary development, saving clients the trouble of coordinating multiple different suppliers separately. The optical inspection unit can expand extra pattern defect detection stations when customers launch new projection lamp styles later. After equipment delivery, our after-sales engineers complete on-site installation, commissioning and operator training within three working days. Many Tier1 auto lighting suppliers adopt HY customized EOL equipment, shortening new product mass production verification cycle by over 40%.
MES Data Traceability System Helps Auto Factories Achieve Digital Intelligent Quality Control
Digital workshop construction has become an inevitable trend for automotive lighting enterprises, and complete full-life data traceability is the core of intelligent quality control. HY projector lamp EOL tester is equipped with self-developed algorithm data acquisition software, automatically collecting current, voltage, projection pattern distortion, luminance and chromaticity data of each tested lamp. All test records are bound with product QR codes and uploaded to workshop MES in real time to realize one-to-one correspondence between projection lamps and inspection data.
Traditional simple test equipment only displays pass/fail results without storing detailed optical and electrical parameter data, making it impossible to trace root causes once mass defective projection lamps appear. Our system supports local storage of 5 years of historical test data, generating multi-dimensional analysis charts such as batch defect proportion and brightness deviation trend curve. Factory QC departments export standardized Excel reports for monthly quality audit meetings. Most clients apply this data system to optimize lamp assembly processes, continuously lowering overall production reject rate.
