Air-Condition Remotor Multi-Function Tester (Single-System) is a compact dedicated device designed for

comprehensive electrical performance and appearance inspection of remote controls.

It adopts a single-system control architecture and integrates two core modules:

electrical performance testing and appearance defect inspection. The device features

a compact footprint and flexible deployment, making it suitable for space-constrained

production lines or small to medium-volume inspection scenarios.

The appearance inspection module can fully detect various surface defects

on remote controls, including front panels, back covers, conventional screen printing,

special laser engraving, and presence or absence of screws. The electrical performance

testing module accurately measures key parameters such as standby current, operating

current, carrier frequency, and luminous intensity. The complete system is equipped with

a programmable control system that enables precise programmatic regulation of supply

voltage, current, and lighting parameters, ensuring consistent testing conditions and

reproducible results. Additionally, it supports shielding of designated special frequency

bands and allows customization of exclusive testing functions according to customer requirements.

The device features a straightforward and rapid modeling operation, and completed

inspection templates can be repeatedly recalled, significantly reducing changeover debugging

workload during product switching. The single-system operates stably with high detection

accuracy and reliability, effectively replacing manual visual inspection, reducing labor intensity,

and adapting to small to medium-volume production as well as laboratory R&D and verification scenarios.

The device's measured production capacity standards are as follows: In the single-system

four-slot configuration, the throughput can reach over 250 units per hour when the back side of

the product is not inspected; when performing full front-and-back inspection, the throughput can

reach over 220 units per hour. The system is configured without an unloader and adopts manual

loading and unloading, meeting the quality control tact time requirements of small to medium-volume

production lines.

I. Electrical Performance Testing

• 1. Battery voltage programmable control: polarity programmable,

• voltage range 1-12V programmable, supports 0V discharge

• 2. Main probe head (universal probe head): supports independent re-testing function

• 3. Auxiliary probe head (multi-function probe head)

• 4. Standby current detection

• 5. Operating current detection

• 6. Carrier frequency deviation detection

• 7. Emission intensity detection

• 8. Infrared code transmission receiving test

• 9. Air conditioner remote control reverse simulation transmission test:

• the host computer simulates and sends a transmission signal to the slave computer,

• which then emits the signal through a light-emitting tube to the remote control under test,

• and the remote control returns an OK/NG signal

• 10. Front and back power-on function test

• 11. Defective product self-locking function (optional, mutually exclusive with automatic rejection)

II. LCD Screen Display Content Inspection

• 1. Detect missing or extra pixels (display defects), minimum detectable area 0.3mm²

• 2. Detect screen shadows (ghosting/short circuits)

• 3. Detect foreign particles, minimum detectable area 0.2mm², grayscale difference > 20 levels

• 4. Detect inconsistent backlight brightness or backlight failure

III. Keypad Silk-Screen Inspection

• 1. Detect missing or extra strokes on silk-screen characters, minimum detectable area 0.2mm²

• 2. Detect incorrect or missing colors between silk-screen and keys (colors must have sufficient contrast, not closely matching)

• 3. Detect presence of fluorescent coating

• 4. Detect foreign particles, minimum detectable area 0.2mm², grayscale difference > 20 levels

• 5. Detect small reset keys, hole diameter ≥ 2.5mm, fixture tolerance < ±0.2mm

IV. Back Cover Laser Engraving Inspection / Back Cover QR Code Recognition, Comparison and Storage

• 1. Detect material mix-up via injection-molded markings

• 2. Detect missing or extra strokes on non-keypad silk-screen, minimum detectable area 0.2mm²

• 3. Detect missing or extra strokes on laser engraving, minimum detectable area 0.3mm²

• 4. QR code recognition

• 5. QR code database duplicate code comparison

• 6. QR code data storage (local storage or upload to external systems)

V. Other Technical Specifications

• 1. Overvoltage output protection: stops output and triggers alarm when voltage exceeds the set value

• 2. Production capacity: Dual-station without unloader: ≥ 600 pcs/h; dual-station with unloader,

• back-side inspection not performed: ≥ 500 pcs/h; dual-station with unloader and full front-and-back inspection:

• ≥ 450 pcs/h; for single-station operation, reduce by 200-250 pcs/h from the corresponding figures above

• 3. False alarm rate: 8%–15% depending on product type

• 4. Software-adjustable input voltage: range 1-5V or 1-12V (selectable), minimum adjustment increment 0.05V

• 5. Automatic NG product rejection: defective units are automatically picked and placed onto the NG conveyor belt at the rear of the equipment (unloader)

• 6. Software interface requirements: graphical test flow configuration interface, carrier frequency display, supports Chinese/English language switching
