[0002] A tempered glass screen protector (also called a tempered glass film) is an external accessory used to protect the screen of a mobile phone. It is durable, drop-resistant, and scratch-resistant. It is made of tempered glass through processes such as high-temperature heating and rapid cooling, resulting in a very hard surface. It can effectively prevent the mobile phone screen from being damaged when subjected to external pressure, and can effectively avoid scratches and drops that may be encountered in daily life, thus extending the lifespan of the mobile phone screen.

[0003] Tempered glass screen protectors have two adhesive sides: one that adheres to the phone screen and the other that needs to adhere to packaging or other protective materials. Therefore, manufacturers need to test both sides of the screen protector to ensure good adhesion before it leaves the factory, in order to guarantee product quality.

After testing one side of the tempered film, it needs to be flipped over. However, in the existing technology, it is generally flipped over manually. This method is time-consuming, has a low degree of automation, and affects the efficiency of testing. Utility Model Content
