Wherein, the display screen can be a rigid display screen or a flexible display screen. In the following embodiments of the present application, a flexible display screen is taken as an example for explanation.

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for disassembling a display device according to the present disclosure. Referring to fig. 2, fig. 2 is a schematic diagram of a dismounting device 200 of a display apparatus provided in the present application. For convenience of description, a length direction of the display apparatus 100 in fig. 2 is defined as a Y-axis direction, a width direction of the display apparatus 100 in fig. 2 is defined as an X-axis direction, and a thickness direction of the display apparatus 100 in fig. 2 is defined as a Z-axis direction.

Referring to fig. 2, the display device 100 includes a display panel 1, an adhesive layer 2, and a housing 3, which are stacked and connected. The disassembling method 10 of the display device 100 is used for disassembling the display screen 1 and the casing 3 of the display device 100. The disassembling method 10 of the display device 100 includes the following steps.

Step 100: the display screen 1 is fixed.

Specifically, referring to fig. 2, the display screen 1 is fixed on the machine table 4. Wherein, the machine table 4 has a supporting surface 43. The display screen 1 is attached to the support surface 43. It will be appreciated that the support surface 43, the display 1, the adhesive layer 2 and the housing 3 are arranged one above the other. When the display device 100 is a mobile phone, the housing 3 is a middle frame of the mobile phone. The machine base 4 includes a first end 401 and a second end 402 (see fig. 4) disposed opposite to each other. The first end 301 of the casing 3 is close to the first end 401 of the machine base 4, and the second end 302 of the casing 3 is close to the second end 402 of the machine base 4. During the process of disassembling the display device 100, the first end 301 of the housing 3 is separated from the display screen 1.

Specifically, referring to fig. 2, the machine table 4 is provided with a cutting member 41 and a clamp 42 opposite to the casing 3. The display device 100 is located between the support surface 43 and the clamp 42. The clamp 42 can be moved close to or away from the support surface 43 to lift the cabinet 3. The cutting member 41 is positioned at one side of the display device 100, and a cutting edge of the cutting member 41 may face the adhesive layer 2. The cutting member 41 is slidable relative to the support surface 43. The cutting member 41 is used to cut the adhesive layer 2 to separate the display panel 1 from the cabinet 3. Specifically, the cutting member 41 is disposed near the first end 401 of the machine platform 4, so that the cutting member 41 firstly cuts the bonding layer 2 between the first end 301 of the housing 3 and the display screen 1.

At split display screen 1 and casing 3's in-process, through fixing display screen 1 on board 4 to dismantle casing 3 from display screen 1, thereby reduce the influence to display screen 1. Particularly, when dismantling flexible display screen, through fixing flexible display screen on board 4, reduce flexible display screen and take place the bending to avoid flexible display screen inside layering and influence and show the function.

It is understood that the display screen 1 can be fixed on the machine table 4 in the following manner.

In a possible embodiment, the display screen 1 is fixed by means of air pressure suction.

Referring to fig. 2, an adsorption area 431 is disposed on the supporting surface 43 of the machine platform 4, and a plurality of adsorption holes 44 are formed in the adsorption area 431; the suction port of the suction device 45 communicates with the plurality of suction holes 44; the display screen 1 is placed on the adsorption area 431, and the air extraction device 45 is opened to enable the adsorption holes 44 to adsorb the display screen 1, so that the display screen 1 is fixed.

Specifically, a plurality of suction holes 44 are formed in the supporting surface 43 of the machine base 4, and the display screen 1 may cover the plurality of suction holes 44. The adsorption hole 44 may penetrate through the supporting surface 43 of the machine platform 4, that is, an opening at one end of the adsorption hole 44 is located on the supporting surface 43, and an opening at the other end of the adsorption hole 44 is communicated with an air exhaust port of the air exhaust device 45. When the air extraction device 45 is opened, the air pressure in the adsorption hole 44 is smaller than the atmospheric pressure, and the display screen 1 can be tightly attached to the supporting surface 43 under the action of the air pressure difference, so that the display screen 1 is fixed on the supporting surface 43. When the air-extracting device 45 is turned off, the air pressure in the suction holes 44 becomes equal to the atmospheric pressure, and the display screen 1 is no longer subjected to the air pressure to be caused to adhere to the supporting surface 43, so that the display screen 1 can be easily separated from the supporting surface 43. The structure for fixing the display screen 1 in the embodiment is simple, and the operation is convenient. It can be understood that the suction force applied to the display screen 1 can be adjusted by adjusting the suction speed of the suction device 45, so as to adjust the adhesion force between the display screen 1 and the supporting surface 43.

It is understood that the size of the adsorption holes 44 may be small, for example, the hole diameter of the adsorption holes 44 may be 1mm to 3 mm.

Through set up a plurality of absorption holes 44 on the holding surface 43 and fix display screen 1, display screen 1 (flexible display screen) can keep laminating smoothly on holding surface 43, and can not take place local bending deformation to take place bending deformation and lead to the layering when avoiding display screen 1 to be fixed in holding surface 43 of board 4. Further, referring to fig. 2 and fig. 3, the arrangement density of the adsorption holes 44 near the first end 401 of the machine 4 may be set to be greater than the arrangement density of the adsorption holes 44 near the second end 402 of the machine 4. When the air extracting device 45 extracts air from the plurality of absorbing holes 44, the absorbing force between the first end 401 of the display screen 1 close to the machine platform 4 and the supporting surface 43 is greater than the absorbing force between the second end 402 of the display screen 1 close to the machine platform 4 and the supporting surface 43. In the process of separating the first end 301 of the casing 3 from the display screen 1, the first end 401 of the display screen 1, which is close to the machine platform 4, and the supporting surface 43 have a large adsorption force, so that the separation process of the first end 301 of the casing 3 from the display screen 1 can be promoted.

Further, referring to fig. 2 and fig. 3, a pair of position-limiting members 46 are formed on the supporting surface 43 of the machine platform 4. Wherein, the pair of stoppers 46 are respectively located at two opposite sides of the adsorption region 431; the display screen 1 is located between the pair of stoppers 46.

Specifically, a pair of stoppers 46 provided at an interval are projected on the support surface 43. The position-limiting member 46 may be a long strip. A pair of stoppers 46 are respectively located on opposite sides of the adsorption region 431. The pair of stoppers 46 are arranged in parallel. The distance between the pair of stoppers 46 may be just the width or length of the display panel 1, so that the display panel 1 can be quickly and accurately placed on the plurality of suction holes 44. When the display screen 1 is placed between the pair of stoppers 46, the display screen 1 covers the plurality of suction holes 44 between the pair of stoppers 46. The plurality of suction holes 44 are sucked by a suction device 45 to fix the display panel 1 to the support surface 43. It will be appreciated that the spacing between the pair of stops 46 may be adjustable to accommodate different sizes of display devices 100.

In another embodiment, the display panel 1 may be fixed to the supporting surface 43 of the base 4 by providing a suction member, an adhesive layer, or the like.

In one possible embodiment, after the display panel 1 is fixed in step 100, the adhesive layer 2 may be softened.

It is understood that the method of softening the adhesive layer 2 includes, but is not limited to, the following embodiments.

In one possible embodiment, the display screen 1 is heated.

Referring to fig. 2, a plurality of heating members 47 are disposed in the machine table 4; the heating element 47 is controlled to heat the display screen 1.

Specifically, referring to fig. 2, a plurality of heating members 47 are disposed in the machine table 4. The heating members 47 are close to and opposed to the supporting surface 43, and the heating members 47 may be arranged alternately with the adsorption holes 44.

Specifically, the heating member 47 may be a heating wire, and the heating member 47 is heated by applying power to the heating member 47. When the display panel 1 of the display device 100 is attached to the supporting surface 43, the heating member 47 heats the adhesive layer 2 through the supporting surface 43 and the display panel 1 to soften the adhesive layer 2.

Further, referring to fig. 3, the heating temperature of the heating element 47 near the first end 401 of the machine platform 4 is controlled to be higher than the heating temperature of the heating element 47 near the second end 402 of the machine platform 4, so that the temperature of the adhesive layer 2 near the first end 401 of the machine platform 4 is relatively higher and the softening degree is higher, and the display screen 1 and the chassis 3 are more easily separated. When the first end 301 of the casing 3 is separated from the display screen 1, the softening degree of the adhesive layer 2 close to the first end 401 of the machine table 4 is higher, and the pulling force of the adhesive layer 2 on the position, close to the first end 401 of the machine table 4, of the display screen 1 can be reduced.

In a possible embodiment, the heating elements 47 near the first end 401 of the machine table 4 are arranged at a density greater than the density of the heating elements 47 near the second end 402 of the machine table 4.

Soften adhesive linkage 2 through heating methods, reduce the cost, can also reach better softening effect, simultaneously, locate in board 4 with heating member 47, do not occupy the space of holding surface 43, and heating member 47 is close to adhesive linkage 2, and heating member 47's heating efficiency is high, and heating member 47 can carry out even and whole heating to adhesive linkage 2.

Further, referring to fig. 2, the detaching device 200 further includes a temperature detector 48. The step of heating the display screen 1 further comprises detecting whether the temperature of the display screen 1 reaches a preset temperature by a temperature detector 48. And if the detection result is yes, pulling one end of the shell 3. The preset temperature can also be 50-150 ℃. The preset temperature may be slightly greater than the temperature at which the adhesive layer 2 softens. It is understood that the temperature detector 48 may be disposed on the supporting surface 43 and attached to the display screen 1.

In other embodiments, the adhesive layer 2 may be softened by means of a heat gun, laser irradiation, ultrasonic waves, low-temperature freezing, solvent dissolution, or the like. When adhesive linkage 2 softens, adhesive linkage 2 diminishes to the adhesive property between display screen 1 and the casing 3, and adhesive linkage 2 is easier to be separated with display screen 1 and casing 3, and adhesive linkage 2 is easier to be cut, so that the separation casing 3 and display screen 1.

Of course, it is understood that the step of softening the adhesive layer 2 may be omitted and the next step may be performed directly.

Step 200: and lifting one end of the shell 3 until a preset gap is formed between the shell 3 and the display screen 1.

In a possible embodiment, please refer to fig. 4 and fig. 5 together, the clamp 42 having two holding

arms

421 and 422 is driven to approach the housing 3 until the two holding

arms

421 and 422 of the clamp 42 are respectively located at two opposite sides of the housing 3; driving the two holding

arms

421, 422 of the holding device 42 to approach each other until holding the housing 3; and lifting the clamp 42 to enable the two clamping

arms

421 and 422 to drive one end of the casing 3 to be gradually away from the display screen 1 until a preset gap 31 is formed between the casing 3 and the display screen 1.

Specifically, referring to fig. 4 and 5, a support 5 is disposed on the supporting surface 43 of the machine table 4, wherein the support 5 may be in an inverted U shape. The ends of the support 5 are fixed to the support surface 43 and the intermediate section 51 of the support 5 is spaced from the support surface 43. Referring to fig. 4, a motor 52 and a lead screw 53 may be disposed on the bracket 5, and the motor 52 may be fixedly connected to the middle section 51 of the bracket 5. The lead screw 53 is rotatably connected to a rotating shaft of the motor 52. The clamp 42 is threaded with a lead screw 53. When the motor 52 rotates, the lead screw 53 extends and contracts, and the lead screw 53 drives the two holding

arms

421 and 422 of the holding fixture 42 to move away from or close to the supporting surface 43. When the housing 3 is fixed, the two holding

arms

421 and 422 of the fixture 42 are driven to approach the housing 3 by controlling the lead screw 53 until the two holding

arms

421 and 422 of the fixture 42 are respectively located at two opposite sides of the first end 301 of the housing 3. The two holding

arms

421, 422 of the holding jig 42 are driven to approach each other until the two holding

arms

421, 422 hold the casing 3. When separating the housing from the display screen, the lead screw 53 is controlled to move away from the supporting surface 43, so that the clamp 42 clamps and pulls the housing 3. Specifically, the first end 301 of the chassis 3 pulls the adhesive layer 2 under the tensile force of the clamp 42. At this time, when the adhesive layer 2 is softened, the adhesive layer 2 is pulled by the housing 3, so that the preset gap 31 is formed between the first end 301 of the housing 3 and the display panel 1.

Wherein, the preset gap 31 is formed by the casing 3 inclining relative to the display screen 1. The housing 3 may be inclined at an angle of 1 to 50 °.

Because the display screen 1 in this embodiment is a flexible display screen, the flexible display screen is formed by laminating multiple layers of flexible materials. The flexible display screen is easy to bend under the action of external force concentrated on local parts, so that layering is generated, and display malfunction of the flexible display screen is caused. By generating a slightly smaller preset gap 31 between the case 3 and the display screen 1 at the side position, the preset gap 31 enables the first end 301 of the case 3 to be separated from the display screen 1, so as to facilitate the cutting of the bonding layer 2 through the preset gap 31; on the other hand, since the preset gap 31 is smaller and located at the side position, the display screen 1 can effectively reduce the risk of delamination caused by too concentrated internal local stress during the process of generating the preset gap 31. Of course, in other embodiments, the display screen 1 may also be a rigid display screen, and the disassembling method provided in the present application is also suitable for disassembling the rigid display screen and the housing 3.

It can be understood that, referring to fig. 4 together, in the process of pulling the first end 301 of the housing 3, the attaching force between the first end 101 of the display screen 1 (the first end 101 of the display screen 1 is adhered to the first end 301 of the housing 3) and the supporting surface 43 is greater than the pulling force of the adhesive layer 2 on the display screen 1, so as to avoid that the first end 301 of the housing 3 cannot be separated from the display screen 1 when the first end 101 of the display screen 1 is separated from the supporting surface 43, that is, the preset gap 31 cannot be formed, and further avoid that the cutting member 41 cannot cut the adhesive layer 2, which results in the failure in the separation of the display screen 1 and the housing 3.

By setting the heating temperature of the heating member 47 near the first end 301 of the housing 3 to be higher than the heating temperature of the heating member 47 near the second end 302 of the housing 3, the temperature of the first end 101 of the display screen 1 is higher than the temperature of the second end 102 of the display screen 1, so that the softening degree of the adhesive layer 2 for bonding the first end 101 of the display screen 1 is higher, and the pulling force of the adhesive layer 2 on the first end 101 of the display screen 1 is small in the process of separating the first end 301 of the housing 3 from the display screen 1.

By setting the arrangement density of the openings of the adsorption holes 44 close to the first end 301 of the casing 3 to be greater than the arrangement density of the openings of the adsorption holes 44 close to the second end 302 of the casing 3, the adhesion force between the first end 101 of the display screen 1 and the supporting surface 43 is greater than the adhesion force between the second end 102 of the display screen 1 and the supporting surface 43, so that the requirement that the first end 101 of the display screen 1 needs a larger adhesion force to resist the pulling force of the adhesive layer 2 is met, the pulling force of the adhesive layer 2 on the second end 102 of the display screen 1 in the process of forming the preset gap 31 is smaller, and the required adhesion force of the second end 102 of the display screen 1 is slightly smaller.

It can be understood that, during the process of pulling the machine shell 3, the heating element 47 is controlled to continuously heat the display screen 1 to make the temperature of the display screen 1 higher than the preset temperature, so that the adhesive layer 2 is in a softened state, and the adhesive layer 2 is broken under the pulling force of the machine shell 3 to form the preset gap 31.

In other embodiments, one end of the housing 3 may be manually pulled.

Step 300: and cutting the bonding layer 2 through the preset gap 31 until the display screen 1 is separated from the machine shell 3.

In one possible embodiment, the display screen 1 is pressed during the cutting of the adhesive layer 2.

Referring to fig. 2, 4 and 6, the detaching device 200 includes a cutting member 41. The cutting member 41 includes a cutting head 411 and a pressing plate 412 connected to the cutting head 411. The cutting head 411 is in a pointed shape, so that the cutting head 411 faces the preset gap 31 and the pressing plate 412 is opposite to the supporting surface 43 of the machine table 4. The cutting member 41 is driven to move, and in the moving process of the cutting member 41, the cutting head 411 cuts the adhesive layer 2 and the pressing plate 412 presses the display screen 1.

Cutting adhesive linkage 2 and cutting 41 pressfitting at the in-process of cutting through cutting 41 display screen 1 to make display screen 1 keep laminating in holding surface 43, the deformation volume that display screen 1 takes place the bending is little, thereby further reduces display screen 1 and takes place the risk of layering, when split display screen 1 and casing 3, has ensured that display screen 1's demonstration function is good.

In a possible embodiment, the direction of cutting the adhesive layer 2 is a direction parallel to the display screen 1.

For example, referring to fig. 3, the cutting member 41 can move along the Y-axis direction. Of course, in other embodiments, the cutting member 41 may be moved in the direction of the X-axis or other direction parallel to the display screen 1.

Further, referring to fig. 3 and fig. 7, the cutting element 41 is driven to slide along a pair of sliding slots 461. The pair of sliding slots 461 is disposed on the pair of stoppers 46. The pair of stoppers 46 extend in the Y-axis direction, and thus the pair of sliding grooves 461 extends in the Y-axis direction.

Specifically, referring to fig. 2, fig. 3 and fig. 7, a sliding slot 461 is respectively disposed on two opposite abutting surfaces 460 of a pair of limiting members 46. Two opposing side walls of the cutter 41 are slidably connected to the slide slots 461. The first driving member 413 is connected to the cutting member 41 to push the cutting member 41 to slide along the sliding slot 461. During the sliding of the cutter 41, the cutter head 411 gradually approaches the preset gap 31 until the adhesive layer 2 is cut. A first drive 413 is provided to push the cutting head 411 to cut the adhesive layer 2, thereby separating the display screen 1 from the housing 3. The stopper surface 462 of the slide groove 461 is disposed opposite to the support surface 43. When the cutting member 41 extends into the predetermined gap 31 or cuts the adhesive layer 2, the limiting surface 462 guides the pressing plate 412, so that the pressing plate 412 presses the display panel 1. The position-limiting surface 462 is substantially parallel to the supporting surface 43, and the distance between the position-limiting surface 462 and the supporting surface 43 may be slightly larger than the thickness of the display screen 1. Specifically, the distance between the limiting surface 462 and the supporting surface 43 may be the sum of the thickness of the display screen 1 and the thickness of the cutting member 41. It can be understood that the distance between the limiting surface 462 and the supporting surface 43 can also be adjustable to be applied to the separation of the display screen 1 and the casing 3 with different thicknesses.

The moving direction of the cutting member 41 is more smooth by driving the cutting member 41 to slide along the sliding slot 461. By setting the distance between the limiting surface 462 and the supporting surface 43, when the cutting member 41 moves to the preset gap 31, the pressing plate 412 of the cutting member 41 is just attached to the display screen 1. The pressing plate 412 of the cutter 41 is always pressed against the display screen 1 while the cutter 41 cuts the adhesive layer 2 along the chute 461, so that the display screen 1 is always kept flat during the cutting of the adhesive layer 2. When the display screen 1 is a flexible display screen 1, the pressing plate 412 of the cutting member 41 is always pressed on the display screen 1, so that the display screen 1 can be further prevented from being bent and layered.

Further, in the process of driving the cutting member 41 to press the display screen 1 through the preset gap 31 and cut the adhesive layer 2 until the display screen 1 is separated from the casing 3, the heating member 47 is controlled to continuously heat, so that the temperature of the display screen 1 is higher than the preset temperature, the adhesive layer 2 is in a softened state, and the cutting member 41 is convenient to cut off the adhesive layer 2.

Further, in the process of driving the cutting member 41 to cut the bonding layer 2 through the preset gap 31 and press the display screen 1 until the display screen 1 is separated from the casing 3, the clamp 42 is pulled, and the clamp 42 drives one end of the casing 3 to gradually get away from the display screen 1. The clamp 42 pulls the machine shell 3, and the pulling force of the machine shell 3 on the bonding layer 2 can break the bonding layer 2, so as to reduce the obstruction to the movement of the cutting member 41.

According to the dismounting method of the display device 100, the display screen 1 is fixed, the bonding layer 2 is softened, and the clamp 42 is controlled to clamp one end of the shell 3 and pull up the end, so that the preset gap 31 is formed between one end of the shell 3 and the display screen 1, and the cutting piece 41 can gradually cut the bonding layer 2 through the preset gap 31 and press the display screen 1 to separate the shell 3 from the display screen 1; wherein, at the in-process of cutting 41 cutting, because cutting 41 pressfitting display screen 1 all the time, can further avoid display screen 1 to receive the pulling force of adhesive linkage 2 and make display screen 1 produce the layering, destroy display screen 1's display function, realized still to ensure display screen 1's display function good at the in-process of split display screen 1 and casing 3.

Referring to fig. 2, fig. 2 is a dismounting device 200 for a display screen 1 according to the present application. The dismounting device 200 of the display screen 1 is used for splitting the display screen 1 and the casing 3 of the display device 100.

Referring to fig. 2, 4 and 6, the dismounting device 200 of the display screen 1 includes a machine table 4, a clamp 42 disposed on the machine table 4 and a cutting element 41. The machine table 4 has a supporting surface 43 for fixing the display screen 1. The clamp 42 is disposed opposite to the support surface 43, and the clamp 42 can be close to or away from the support surface 43. The clamp 42 is used for lifting the casing 3 until a preset gap 31 is formed between the display screen 1 and the casing 3.
