Efficient Solution for Detecting the Flatness of Smartphone Screen Installation
Smartphone Screen Installation Detection Solution
In the production of smartphones, the accuracy of screen installation is crucial, as it directly affects the quality and performance of the device. Traditional detection methods may face challenges such as insufficient precision and low efficiency. Our GFL-G Series Laser Displacement Sensors offer a high-precision, efficient solution for detecting smartphone screen installation with micron-level accuracy.
Challenges
In smartphone production lines, the connection between the screen and the body requires extremely high precision. Even minor deviations can result in connection errors, display issues, and ultimately impact user experience and product quality.
High-Precision Laser Displacement Sensor GFL-G Series
1. High-Precision Measurement: Provides measurement accuracy of 2 μm within a range of 26 mm to 34 mm, and 75 μm within a range of 100 mm to 400 mm.
2. Triangulation Method: Utilizes triangulation to detect displacement, flatness, thickness, vibration, distance, and diameter.
3. Data Acquisition and Analysis: Supports the statistics of maximum, minimum, and average values, with waveform display and data export for further analysis.
4. Differential Calculation and Limit Setting: Allows differential calculation between two sensors, with upper and lower limit settings and zeroing display functionality.
5. Multiple Output Options: Compatible with RS485, analog output, and switch output to meet diverse industrial needs.
6. Compatibility: Connects seamlessly to systems such as computers, PLCs, and IPCs, suitable for various industrial automation applications.
Solutions
To ensure the accuracy of smartphone screen installation, three GFL-G Series laser displacement sensors are deployed above the critical detection points of the screen, including the four corners and the center area. This arrangement provides comprehensive coverage of the inspection range, ensuring precise and stable measurements.
1. Sensor Installation
▪️Mount the sensors on calibrated, stable brackets to avoid measurement errors caused by vibration or external interference.
▪️Ensure the sensors are positioned perpendicular to the detection surface, with the distance maintained within the specified range for optimal performance.
2. Cable Connections
▪️Securely connect the sensor cables to prevent loosening or signal transmission issues.
▪️Check that the cable routing complies with industrial standards to avoid signal loss or disconnection due to bending or pulling.
3. Inspection Process
▪️Use the sensors' multiple output modes (such as RS485, analog output, etc.) to transmit real-time detection data to PLC or IPC systems for analysis.
▪️Utilize the differential calculation function and upper/lower limit settings to promptly determine whether the screen position meets installation standards, preventing defective products from proceeding to the next stage.
