Upon heating, the sealant 18 between the front housing 11 and the screen 10 in the front housing assembly 6 softens and decreases in viscosity relative to the sealant that would otherwise set before heating.

In a possible embodiment, the heating device is an electric heating device disposed in the accommodating space of the screen-detaching box 8, the electric heating device may be a resistance heating wire or an electric heating plate, the electric heating plate is a PTC (Positive Temperature Coefficient thermistor) plate, and a lead connected to the electric heating device is connected to a power supply located outside through an inlet and an outlet of the screen-detaching box 8. When the power supply is energized to the electric heating device through the wire, the electric heating device is heated and radiates heat to the surroundings, and the sealant 18 in the front housing assembly 6 on one side of the electric heating device is softened and reduced in viscosity by continuous high-temperature heating.

The working process of the screen dismounting device in the above embodiment is as follows:

disassembling a front shell assembly 6 and a rear shell of the electronic equipment, and hermetically connecting a front shell 11 and a sealing seat 7;

placing the front shell assembly 6 and the sealing seat 7 which are connected into a whole in a heating chamber of a high-temperature box for heating, so that the sealant 18 becomes soft and the viscosity is reduced;

after heating is completed, the front shell assembly 6 and the sealing seat 7 are taken out of the high-temperature box and are placed into the accommodating space of the screen disassembling box 8;

the air inlet joint 9 of the air inlet pipeline 2 is connected to a quick joint 17 on the sealing seat 7, the electromagnetic switch valve 5 in the pneumatic device is controlled to be switched from a closed state to an open state, the pneumatic device conveys air into a sealing cavity 15 formed by the front shell assembly 6 and the sealing seat 7 through the air inlet pipeline 2, the pressure of the air can be gradually increased through adjusting the pressure regulating valve 4, and the screen 10 is pushed to be separated from the front shell 11.

Because the sealed glue that condenses before not heating after the heating becomes soft and viscidity reduces for between screen and the preceding shell because the adhesive force that sealed glue produced reduces, consequently the screen can break away from preceding shell under less gas action power, and less gas action power can not harm screen and preceding shell in the process that the screen breaks away from preceding shell, thereby realizes the non-damaged separation of screen and preceding shell, also makes the screen after the separation and preceding shell can reuse, avoids extravagant.

The gas delivered by the pneumatic device to the sealed cavity may be a pressure gas higher than the standard atmospheric pressure, or may be an atmospheric pressure gas equal to the standard atmospheric pressure, and since the space of the sealed cavity 15 is limited, even after the atmospheric pressure gas is continuously input into the sealed cavity 15, the heated screen can be pushed away from the front case. The heating temperature and the heating time can be determined according to the type of the sealant, the dosage of the sealant and other factors. In consideration of different types of sealants with different adhesive forces, the heating process can be carried out at a higher heating temperature for a longer heating time under the conditions that the adhesive force of the sealant is larger and the using amount of the sealant is larger. For example, the heating temperature may be set to 75 degrees or more and the heating time may be set to 15 minutes or more. It is understood that the heating temperature and the heating time period in the heating device should be set not to exceed the endurance limit of the screen and the front case in the front case assembly, or within a safety endurance range pre-configured to indicate the endurance limit. In one possible embodiment of the present application, the heating temperature may be 85 degrees celsius and the heating time may be 30 minutes.

In addition, for the electronic device which does not have the waterproof function or has poor sealing performance between the front shell 11 and the rear shell, a sealing piece for sealing the contact area of the sealing seat 7 and the front shell 11 can be additionally arranged when the sealing seat is connected with the front shell 11, so as to ensure the sealing performance of the sealing cavity 15.
