Rigorous Quality Control
Magique Huaer Red Light Therapy Equipment Quality Inspection Process
Model Configuration Verification
Control System Configuration: Verify that the control system configuration of the red light therapy equipment matches the order requirements, ensuring that all functions are properly configured and operational.
Visual Inspection: Check that the installation frame and outer shell are free from any packaging materials (such as plastic) or other obstructions that could hinder use.
LED Light Strip Layout and Installation
LED Light Strip Layout: Confirm that the LED light strips in the red light therapy equipment are installed according to the order specifications. Check that the installation direction of the light strips in both the upper and lower compartments is consistent, with uniform gaps between the strips, not exceeding 2.5mm, and both ends aligned.
LED Bulb Integrity: Ensure that all LED bulbs on the light strips are undamaged, with no cold soldering, flickering, or dimming issues.
Appearance and Label Inspection
Logo and Warning Labels: Verify that the product has the correct logo and warning labels as per the order requirements, ensuring they are free from bubbles, misalignment, or fingerprints.
Shell Coating Quality: Inspect the color and coating of the device shell for consistency, ensuring no black spots, scratches, bubbles, or impurities. The appearance should be flawless when viewed from a distance of 60 cm.
Glass Surface Inspection: The glass should be free of dirt, dust, fingerprints, scratches, and should remain clean.
Electrical Connections and Wiring Inspection
Wire Connector Installation: Check all wire connections to ensure there are no exposed copper wires, reverse polarity, or incorrect wiring (such as fire and neutral wires being swapped). Ensure all wire connectors are clearly labeled and correctly applied.
Wire Joint Inspection: Confirm that the terminals of multi-core wires are securely attached and free from incorrect connections or damage.
Cabinet Interior and Equipment Cleaning
Internal Cleaning: Inspect the equipment's interior to ensure it is free from any debris (such as metal filings, plastic shavings, dust, etc.) that could affect the equipment’s functionality.
Aluminum Material Inspection: Ensure that aluminum components are free from deformation, scratches, dents, or rust, and that the surface appearance is flawless.
Functionality Testing
Control System Functionality: Confirm that the control system of the red light therapy equipment operates correctly, including testing all buttons and the touchscreen for smooth operation of power on/off, time adjustments, volume control, and the activation/deactivation of the machine.
External Control Function Inspection: Verify that external control functions, such as Bluetooth and Wi-Fi, are working properly. Bluetooth should be connectable and play sound without distortion, and the Wi-Fi settings should meet the order specifications.
Heat Dissipation Fan and Temperature Control Testing
Fan Operation: Confirm that the heat dissipation fan works properly, with no malfunctions such as non-operation, abnormal noise, or reverse rotation.
Temperature and Fan Sensitivity Test: Ensure the machine’s temperature is within the specified range during operation, with the glass surface temperature not exceeding 50°C and minimal heat generation.
Electrical and Voltage Testing
Voltage Confirmation: Check that the device's voltage specifications align with the order requirements.
Wire and Light Board Contact: Ensure that no wires are in direct contact with the heat dissipation aluminum plate to prevent overheating or short circuits.
Infrared Light and Transmittance Testing
Infrared Light Activation: Use a professional measuring instrument or open the phone camera in a dark environment to observe whether the infrared light is functioning correctly.
Transmittance Test: Measure the transmittance of the glass to ensure the light intensity (Red > 129mW/cm²) meets the requirements and the device does not overheat.
System Settings and Default Startup
System Settings Test: Confirm that the default settings of the equipment match the order specifications (e.g., fan start temperature, alarm temperature, delay time, etc.). Ensure the system can be adjusted properly through the control system as per the order.
Aging Test
Aging Test: Perform an aging test on each device for a minimum of 48 hours, with 8 hours of continuous testing each day, to ensure the device remains stable and operational after long-term use.
Final Appearance and Function Confirmation
Final Appearance Inspection: Confirm that the device’s appearance is neat and that there are no defects in the glass, metal shell, screws, or other parts.
