Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, the method for separating a cover plate and a display panel of an electronic device according to the present invention includes,
providing a plastic sheet 10, inserting the gap between the cover plate 20 and the display panel 30 from the lower side of the visible region of the cover plate 20, and moving to the side, inserting the plastic sheet 10 between the cover plate 20 and the silicone adhesive 40;
putting the electronic equipment into an industrial refrigerator integrally;
taking out the electronic equipment;
breaking the cover plate 20 and the display panel 30;
heating the display panel 30 on a heating plate to soften the first optical cement on the display panel 30;
bonding and removing the first optical cement by using the second optical cement;
heating the cover plate 20 on a heating plate to soften the third optical cement on the cover plate 20;
bonding and removing the third optical cement by using the fourth optical cement;
the cover plate 20 and the display panel 30 are recovered.
According to the invention, the plastic sheet 10 is inserted between the cover plate 20 and the display panel 30, and an outward pressure can be applied to the cover plate 20 and the display panel 30 in advance, so that a pre-separation force exists between the cover plate 20 and the display panel 30, and the separation is convenient; the electronic equipment is rapidly frozen, the optical cement is stored at low temperature, the colloid becomes hard, the adhesive force to the adhesion surface is greatly reduced, and the viscosity of the optical cement between the cover plate 20 and the display panel 30 is weakened; the cover plate and the display panel are heated to soften the residual optical cement on the surface, so that the optical cement is convenient to clean.
The thickness of the plastic sheet 10 is not more than 0.1mm, and the plastic sheet may be any shape such as a circle, a square, a triangle, etc.
In this embodiment, the plastic sheet 10 is rectangular, preferably square.
The size of the plastic sheet 10 is not limited to a large amount, and in the present embodiment, the plastic sheet 10 is preferably a square sheet having a length and a width of 20mm and a thickness of 0.1 mm.
One or more plastic sheets 10 may be interposed between the cover plate 20 and the display panel 30 to be separated therefrom, and the number of the plastic sheets 10 is not limited thereto.
In the present embodiment, the plastic sheet 10 is preferably two sheets, and is inserted into the gap between the cover plate 20 and the display panel 30 from below the visible region of the cover plate 20, and is moved to the left and right, respectively, so that the plastic sheet 10 is inserted between the cover plate 20 and the silicone adhesive. The plastic sheets 10 are uniformly arranged on both sides of the cover plate 20 and the display panel 30, so that a part of left and right regions between the cover plate 20 and the display panel 30 are in a pre-separation state, which is helpful for subsequent separation, and avoids damage to the cover plate 20 or the display panel 30 during separation.
The set temperature of the industrial refrigerator is-120 to-100 ℃. Preferably, the set temperature is-110 ℃. After the optical cement is stored at-110 ℃, the adhesion to the surface of the cover plate 20 is greatly reduced, and the optical cement hardens, facilitating the subsequent separation of the cover plate 20 from the display panel 30.
The storage time of the electronic equipment in the industrial refrigerator is 2-4 min. In the preferred embodiment, the storage time is 3 min.
In this embodiment, the specific separation method of the cover plate 20 and the display panel 30 is as follows:
the cover plate 20 is held by one hand, and the other hand is pulled off by the other hand, so that the display panel 30 is separated from the cover plate 20 along the position where the plastic sheet is inserted, a small portion of the optical cement remains on the surface of the cover plate 20, and a large portion of the optical cement remains on the surface of the display panel 30.
After the electronic device is frozen and the cover plate 20 and the display panel 30 are manually opened, the separation force generated at the plastic sheet 10 can be gradually transmitted to other places, which facilitates the rapid separation of the cover plate 20 and the display panel 30.
The heating temperature of the heating plate is 55-65 ℃. In this embodiment, the heating temperature is preferably 60 ℃. After heating, the optical cement can be softened again, and subsequent removal is facilitated.
When heating, the side of the cover plate 20 with the third optical cement is far away from the heating plate. The side of the display panel 30 having the first optical cement is away from the heating plate.
Preferably, in the embodiment, when the optical cement is removed, the optical cement block with the same colloid as the residual optical cement is used to remove the residual optical cement, and because the optical cement has elasticity, the residual optical cement can be stretched and removed after being adhered to the optical cement block, and the process is repeated for multiple times until the optical cement block is cleaned up.
Specifically, a piece of second optical glue with the same texture as the first optical glue on the display panel 30 is taken to be bonded with the first optical glue, when the first optical glue is bonded with one end, the first optical glue is pulled up gradually by hand, and the first optical glue is bonded with the second optical glue and removed from the display panel 30 because the first optical glue has elasticity and can be stretched. Similarly, a fourth optical cement with the same texture as the third optical cement on the cover plate 20 is taken to be bonded with the third optical cement, and when the third optical cement is bonded with one end, the third optical cement is gradually pulled up by hand, and is removed from the cover plate 20.
Preferably, after the optical cement is removed, the cover plate 20 and the display panel 30 are placed in a plastic suction tray for recycling. Is convenient to recycle.
According to the invention, the plastic sheet is inserted between the cover plate and the display panel, and outward pressure can be applied to the cover plate and the display panel in advance, so that the cover plate and the display panel have a pre-separation force, and the separation is convenient; the electronic equipment is rapidly frozen, the optical cement is stored at low temperature, the colloid becomes hard, the adhesive force to the adhesion surface is greatly reduced, and the viscosity of the optical cement between the cover plate and the display panel is weakened; the cover plate and the display panel are heated to soften the residual optical cement on the surface, so that the optical cement is convenient to clean.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
