In today's consumer electronics market, foldable screen phones have become a hot spot for consumption due to their novel form and large screen advantages. However, frequent folding and unfolding actions put higher demands on their reliability and durability,making the "aging test" a core link in the quality control of foldable phones. The high-precision static torque sensor serves as the "nerve center" of this test, and the accuracy of the test data depends almost entirely on the performance of the torque sensor - it is like an "electronic eye" that captures subtle torque changes during the folding process in real time.
Why choose a torque sensor?
In the aging test of folding screen mobile phones, the torque of the hinge is a key parameter, which directly reflects the tightness and friction of the hinge. Excessive torque may cause folding difficulties or screen damage,while too small torque may make the screen unable to stably unfold or close.By real-time monitoring of the torque changes of the hinge during the folding process, we can:
Evaluate the durability of the hinge: Long-term repeated folding will cause wear or deformation of the internal structure of the hinge, thereby affecting the torque value. By monitoring the torque change trend, the aging degree and remaining life of the hinge can be evaluated.
Optimize hinge design: Test data can help engineers analyze the advantages and disadvantages of hinge design, thereby optimizing the hinge structure, materials and lubrication methods, and improving its durability and stability.
Ensure product quality: By setting the upper and lower limits of the torque range,the foldable screen phone can be judged as qualified or not, ensuring that every device shipped meets the quality standards.
LT-03 Static Torque Sensor: A Reliable Choice for Precise Measurement
Many mobile phone manufacturers that collaborating with our company have selected the LT-03 static torque sensor for similar solutions. This sensor has the following advantages:
Wide measurement range: With selectable ranges of 0-1, 2, 3.5, 10, 20, 30, 50, and 100 NM, which is suitable for folding screen mobile phones of different sizes and structures to meet diversified test needs.
High precision: The non-linearity of this sensor is ±0.1%F.S., with extremely high precision, which can accurately measure the torque value of the hinge and ensure the reliability of test data.
Good stability: It has good anti-interference ability and long-term stability, and can maintain stable performance during long-term testing.
Simple structure: The structure is relatively simple, easy to install and maintain.
Low cost: Compared with the dynamic torque sensor, the cost is usually lower.
Case summary
By integrating static torque sensors in the aging test equipment for folding screen mobile phones,we can achieve precise measurement and monitoring of hinge torque, providing strong support for evaluating hinge durability, optimizing hinge design, and ensuring product quality. In torque measurement applications, it is the most cost-effective choice.
