The seating groove 170 may be formed in substantially the same shape as the lower surface of the display 20 disposed on the stage 120. At least a portion of the display 20 may be inserted into the seating groove 170. In this case, the window 200 of the display 20 and the adhesive layer 210 may be exposed on the upper surface of the stage 120. That is, the thickness of the display 20 may be greater than the depth of the seating groove 170. In the exemplary embodiment, when the display 20 is seated in the seating groove 170, the display panel 220 can be completely inserted into the seating groove 170. [ The vertical positional relationship of the above-described components will be described later in detail. The seating groove 170 formed on the stage 120 can fix the display 20 so that the display 20 does not deviate from the stage 120 during the separation operation of the window 200. [

On the base 130, a conveying means for conveying the stage 120 is located. The transfer means can advance the stage 120 in a certain direction on the base 130. [ The transfer means may be positioned between the stage 120 and the base 130 to move the stage. In an exemplary embodiment, the transport means may include two guide rails 150. When the conveying means includes two guide rails 150, a movable member 160 capable of moving on the guide rails 150 may be disposed under the stage 120. The conveying means for advancing the stage 120 is not limited thereto, and various conveying means are applicable. For example, the stage 120 can be moved using one guide rail.

The rotating means can rotate the stage 120 360 degrees and rotate only within a certain angle range. In addition, the rotating means can not only rotate the stage 120 in one direction, but also reciprocally rotate within a certain angle range.

In an exemplary embodiment, the rotating means may comprise a bearing having a rotational axis. The rotating means can be fastened to the stage 120. When one end of the rotating means is fastened to the stage 120, the other end can be fastened to the conveying means. In this case, the conveying means can advance the stage 120 in a predetermined direction, and at the same time, the rotating means can rotate the stage 120. In this case, the stage 120 can proceed in parallel with the linear motion and the rotational motion. When the stage is parallel to the linear motion and the rotational motion, the stage may rotate only in one direction, but may proceed in a reciprocating rotational motion within a certain angle range.

The transfer and rotation of the stage 120 can be performed automatically or manually. If performed manually, the stage 120 may further include a handle 180. The handle 180 can be mounted on the front side with respect to the traveling direction of the stage. Although the handle 180 fixed to the stage 120 is illustrated in the drawing, the handle may be designed to be movable from the side of the stage in accordance with the rotation of the stage. In this case, a guide rail may be disposed on the side surface of the stage so that the handle can be moved.

On the stage 120, a disassembly blade 110 is disposed. The width W of the disassembly blade 110 may be 3 mm to 10 mm, but the present invention is not limited thereto, and the disassembly blade 110 having various widths may be applicable depending on the size of the display.

The disassembly blade 110 may be secured by two supports 141, 142 located on the base 130. [ Specifically, one end of the disassembling blade 110 is supported by the first support 141, and the other end of the disassembling blade 110 is supported by the second support 142. In this case, the distance between the first support 141 and the second support 142 may be greater than the longitudinal or transverse length of the stage 120, and may be greater than the diagonal length of the stage 120. When the distance between the first support 141 and the second support 142 is greater than the vertical length or the transverse length of the stage 120, the stage 120 is moved to contact the first support 141 and the second support 142 And can pass between the first support 141 and the second support 142. When the distance between the first support 141 and the second support 142 is larger than the diagonal length of the stage 120, even if the stage 120 is tilted at a specific angle and moves, It will be possible to pass between the second supports 142.

When the stage 120 rotates, the distance between the first support 141 and the second support 142 may be larger than the diameter of the outermost circle that the stage 120 can draw while rotating. The diameter of the outermost circle may be twice the distance to the edge of the stage 120 farthest from the rotation axis. In this case, the stage can pass between the first support 141 and the second support 142 without touching the first support 141 and the second support 142 in spite of the rotation of the stage 120 .

In some other embodiments, the display window separating apparatus may further include a temperature control device for heating the adhesive layer 210 of the display 20.

The temperature regulating device may be disposed on the base 130. However, the position of the temperature control device is not limited, and may be installed separately from the base 130 in some cases.

In an exemplary embodiment, the temperature controller can heat the stage 120. [ As the stage is heated, the temperature of the adhesive layer of the display disposed on the stage can be raised. The temperature regulating device may heat the base 130 in addition to directly heating the stage 120, or may heat the space itself in which the separating operation is performed. In this case, the heat transfer method will be conduction or convection.

When the adhesive layer 210 is heated, the cohesive force between the adhesive molecules constituting the adhesive layer 210 can be weakened. If the cohesive force between molecules constituting the adhesive layer 210 is weakened, the adhesive force between the display panel 220 and the window 200 becomes weak and the entry of the disassembly blade 110 becomes easier than when the adhesive layer 210 is not heated have.

The thermostat may be able to perform not only heating but also cooling as required. When the cohesive force between the adhesive molecules is weakened at the time of cooling according to the component of the adhesive layer 210, the window layer can be easily separated by cooling the adhesive layer 210.
