[0002] In the current electronic device manufacturing process, the display screen is usually installed in a specific housing, which is designed to provide the necessary protection and support for the display screen. However, during the manufacturing and assembly process of the display screen, the display screen needs to be removed from the housing for subsequent processing or assembly with other components, so the demolding step is a key link in the manufacturing process.

[0003] Existing demoulding technologies often involve complex mechanical structures. The most common method is to use a clamping claw assembly to press the carrier to separate the display screen from the housing. Although this demoulding method can accomplish the task to a certain extent, it has the following significant defects:

Such damage not only affects the appearance quality of the product, but may also have a negative impact on the functionality and durability of the display.

[0005] Secondly, since vacuum negative pressure may be formed between the display screen and the shell, it is more difficult to separate the display screen from the shell. Under the effect of vacuum negative pressure, the display screen is tightly adsorbed on the shell, and a large force is required to overcome this adsorption force and remove the display screen from the shell. This forced separation process may further aggravate the damage to the display screen. Summary of the invention

[0028] See also Figure 1As shown, in this embodiment, the installation mechanism 100, the air knife mechanism 300 and the adsorption mechanism 200 are arranged in sequence from top to bottom, wherein the installation mechanism 100 is connected to an external mobile device, which is used to connect the adsorption mechanism 200 and the air knife mechanism 300, and at the same time drive the above two to move synchronously up and down, so as to achieve the purpose of the adsorption mechanism 200 approaching / moving away from the display screen to be demolded. At least two air knife mechanisms 300 are used to supply air to the edge of the display screen to be demolded to destroy the negative pressure vacuum environment between the display screen and the shell. Based on the setting of the air knife mechanism 300, air enters between the display screen to be demolded and the shell, so that the display screen is in a loose state inside the shell.
