In the production process of smartphones and tablets, it is essential to ensure that each finished product is equipped with a complete protective film before leaving the factory. Therefore, the integrity inspection of screen protectors (such as tempered glass films, transparent films, etc.) is a crucial step. Sensors are required to detect the presence of these films. When a sensor identifies missing or substandard films, it can automatically trigger an alarm system or halt the production line to address the issue promptly.

Sensor selection analysis:

1. The color and grayscale of the film vary, and the probability of false detection is higher when using simple two-point teaching

2. Sensors are required for high-speed detection

solution

1. Using Akusense ESE series color sensor, it integrates color and color dual modes, which can detect both different colors and grayscale differences between two different colors

2. High precision detection: Color code sensors detect colors or color codes by emitting light sources and receiving light reflected back from target objects. When detecting mobile phone film, it can accurately identify the color, transparency and other characteristics of the film, thereby determining the presence or absence of the film, ensuring the consistency and accuracy of the products on the production line.

3. Quick response capability: Color code mode 0.05ms, color mode 0.2ms, able to complete the detection process in a very short time, achieving high-speed production.

4. Non contact detection: The Meiji ESE series color code sensor adopts a non-contact detection method, which will not cause any damage to the phone screen. This detection method not only ensures the integrity of the product, but also extends the service life of the sensor.

5. Strong adaptability: The color code sensor can adapt to different colors and transparency of mobile phone films. By adjusting the parameters of the light source and receiver, sensors can adapt to the detection needs in various complex environments.
