Description
Technical Field
The present invention relates to a preprocessing device for a display part, and more particularly, to a preprocessing device for a display part capable of preventing a screen display part from being damaged.
Background
In general, a portable terminal is provided with a display portion. The display portion includes a screen display portion and a cover glass. The outer side surface of the screen display part is bonded with a cover glass through an optical bonding layer. The screen display unit is formed by laminating a thin film transistor, a photodiode layer, and a polarizing layer, or a liquid crystal, a color filter, and a polarizing layer.
When a cell defect or a pixel defect occurs in the screen display portion, the screen display portion and the cover glass are separated, thereby reusing the screen display portion and the cover glass.
However, in the related art, when the cover glass is separated from the screen display portion after the screen display portion and the cover glass are heated to a high temperature, the optical adhesive layer is not separated, and as a certain adhesive layer within the screen display portion is separated, there is a possibility that the screen display portion may be damaged.
In addition, in the low temperature state, the hardness of the adhesive layer inside the screen display portion is relatively weaker than the hardness of the optical adhesive layer of the cover glass. Therefore, when the screen display portion is separated in a low temperature state, there is a possibility that the screen display portion may be damaged as a certain adhesive layer inside the screen display portion is separated due to pressure applied by the separation plate.
The background art of the present invention is disclosed in korean laid-open patent publication No. 2010-0034149 (2010.10.28 discloses, title of the invention: touch sensing unit separation and washing method for reusing touch sensing units).

Referring to fig. 1 to 6, the preprocessing device for a display part according to an embodiment of the present invention includes a placing stage 110, a heating part 120, and a partial separation part 130.
The display portion 10 includes a screen display portion 11 and a cover glass 15. The screen display portion 11 and the cover glass 15 are bonded by an optical adhesive layer 13. The optical adhesive layer 13 adheres the screen display portion 11 and the edge portion of the cover glass 15. The optical adhesive layer 13 is formed in a rectangular frame shape. Organic Light Emitting Diodes (OLEDs) may be used as the screen display unit 11. Of course, a Quantum dot Light Emitting diode (QLED), a Liquid Crystal Display (LCD), or the like may be used as the screen Display unit 11.
The pretreatment device is a device for partially separating the display section 10 and one end section on the side of the bezel section of the cover glass 15.
The placing stage 110 places the cover glass 15 of the display section 10 and cools the display section 10.
The placing table 110 includes a table 111, a cooling part 113, and an extraction module 115.
The table 111 is placed with the cover glass 15 of the display section 10, and the table 111 is formed with a lead-out section 112. The lead out portion 112 may be a lead out hole formed in a substantially "T" shape. The lead portion 112 is formed in various manners.
The cooling part 113 is provided on the table 111 to cool the display part 10. The cooling unit 113 is a cooling line through which a cooling medium such as air (air) or a cooling liquid flows. The cooling wire is arranged on the table 111 in a zigzag shape. The cooling medium flows along the cooling line, so that the table 111 can be cooled. At this time, when the cover glass 15 of the display section 10 is heated by the heating section 120, the cooling section 113 cools the display section 10 to prevent the temperature of the screen display section 11 from exceeding 70 ℃.
The lead-out module 115 is provided in the lead-out portion 112 so as to be able to be led out, and sucks the cover glass 15. After one end of the optical adhesive layer 13 is separated from the cover glass 15, the lead-out module 115 transfers the display unit 10 to a subsequent step.
The lead-out module 115 includes a swing arm portion 116, an adsorption port 117, and a swing drive portion 118.
The swing arm portion 116 is provided rotatably to the lead portion 112. Before the display section 10 is placed on the table 111, the swing arm section 116 is drawn into the lead-out section 112. The swing arm portion 116 is formed in a substantially "T" shape so as to be able to be introduced into the lead-out portion 112. The swing arm portion 116 includes a connection arm 116a connected to the swing driving portion 118 and a swing head 116b formed to have a width larger than that of the connection arm 116 a.
The suction port 117 is provided in the swing arm portion 116 so as to suck the lower portion of the cover glass 15. A plurality of suction ports 117 may be provided on the swing head 116 b. The suction port 117 is connected to a vacuum device (not shown).
The swing drive unit 118 is connected to the swing arm unit 116 so as to rotate the swing arm unit 116. As the swing drive unit 118 is driven, the swing arm 116 rotates about the rotation axis of the swing drive unit 118. A motor unit may be used as the swing drive unit 118.
The heating part 120 is disposed apart from the placing stage 110 at one side of the placing stage 110, and locally heats one end portion of the optical adhesive layer 13 of the display part 10. At this time, the cover glass 15 is provided above the heating unit 120, and the optical adhesive layer 13 and the screen display unit 11 are laminated above the cover glass 15. One end portion of the optical adhesive layer 13 is a portion corresponding to the frame region of the display section 10. The heating part 120 is formed long in the width direction of the display part 10. A heater may be used as the heating portion 120. One end of the optical adhesive layer 13 is indirectly heated by heating the one side of the cover glass 15 by the heating unit 120.
The heating part 120 locally heats one end portion of the optical adhesive layer 13, so that the screen display part 11 can be prevented from being heated to 70 ℃ or more by the hot air of the heating part 120. Therefore, the adhesive layer (not shown) of the screen display portion 11 is prevented from being softened by the hot air of the heating portion 120, and thus the screen display portion 11 can be prevented from being damaged when the cover glass 15 is partially separated from the screen display portion 11.
The heating unit 120 locally heats about 3mm to 10mm of one end portion of the optical adhesive layer 13. The heating temperature of the heating part 120 is set to be in the range of 40 to 150 ℃. Since the hardness of the optical adhesive layer 13 can be reduced by heating the optical adhesive layer 13 to the heating temperature, the one end portion of the optical adhesive layer 13 can be easily separated from the cover glass 15.
The preprocessing device for a display section further includes a moving module 140 provided to move any one of the placing stage 110 and the heating section 120. When the placing table 110 is provided to be movable, the swing arm portion 116 is also provided to move together with the placing table 110.
Since either one of the placing table 110 and the heating part 120 moves, the interval between the placing table 110 and the heating part 120 can be adjusted. Therefore, even if the length of the display section 10 changes, the heating section 120 moves in correspondence with the one end portion of the optical adhesive layer 13, so that the one end portion of the optical adhesive layer 13 can be locally heated regardless of the length of the display section 10.
The moving module 140 may take various forms as long as it can move either one of the placing stage 110 and the heating part 120. Next, an example of the moving module 140 will be described.
The moving module 140 includes a ball screw (ball screw)141 and a position adjusting portion 142. The ball screw 141 is connected to either the mount table 110 or the heating unit 120. At this time, the placing table 110 or the heating unit 120 is screwed to the ball screw 141. Accordingly, the placing table 110 or the heating unit 120 moves as the ball screw 141 rotates.
The position adjusting unit 142 is connected to the ball screw 141 so as to rotate the ball screw 141. The position adjusting part 142 may be a motor part. As the position adjusting portion 142 is driven, the ball screw 141 rotates. When the ball screw 141 rotates, the ball screw 141 does not move in the longitudinal direction.
Also, the position adjusting part 142 may be a handle connected to the ball screw 141. As the handle is manually rotated, the ball screw 141 is rotated.
The preprocessing device for a display part may further include a heat insulating member 150 disposed between the placing stage 110 and the heating part 120. The heat insulating member 150 prevents the hot air of the heating part 120 from heating the placing table 110. Therefore, the heating part 120 can locally heat the one end part of the optical adhesive layer 13.
The partial separation portion 130 partially separates the heated portion of the optical adhesive layer 13 and the cover glass 15. The partial separation portion 130 may be a separation plate interposed between the heated portion of the optical adhesive layer 13 and the cover glass 15. As the separation plate enters between the heated portion of the optical bonding layer 13 and the cover glass 15, the heated portion of the optical bonding layer 13 is separated from the cover glass 15.
The operation of the preprocessing device for a display unit according to an embodiment of the present invention configured as described above will be described below.
As the swing driving portion 118 is driven, the swing arm portion 116 is drawn into the drawing portion 112 of the table 111. The position of the heating part 120 may be adjusted to fit the size of the display part 10 that is the object of the preprocessing. In this case, the ball screw 141 is rotated by the motor unit or the position adjusting unit 142 such as a handle, and the position of the heating unit 120 can be adjusted. Therefore, it is not necessary to manufacture a preprocessing device for display according to the size of the display unit 10.
The display section 10 is supplied to the stage so that the cover glass 15 is placed on the stage 111. At this time, one end portion of the optical adhesive layer 13 corresponds to the heating portion 120.
The table 111 is cooled as the cooling portion 113 of the placing table 110 is supplied with the cooling medium. Then, the heating unit 120 generates heat by supplying power to the heating unit 120. Then, the vacuum device (not shown) is driven, and the suction port 117 sucks the cover glass 15 by vacuum pressure.
As the heating part 120 locally heats the cover glass 15, the optical adhesive layer 13 is locally heated, and at the same time, the cooling part 113 cools the cover glass 15 through the stage 111. Therefore, even if the cover glass 15 is heated by the heating section 120, it is cooled again by the cooling section 113, and the entire screen display section 11 can be prevented from being heated. Further, since the heat insulating member 150 is disposed between the heating unit 120 and the placing table 110, the placing table 110 can be prevented from being heated by the heating unit 120.
When one end portion of the optical adhesive layer 13 is locally heated, flexibility of the one end portion of the optical adhesive layer 13 is improved. When the partial separation portion 130 enters between the heated portion of the optical adhesive layer 13 and the cover glass 15, one end portion of the optical adhesive layer 13 is partially separated from the cover glass 15.
The swing driving portion 118 is driven in a state where the partial separation portion 130 is sandwiched between the optical adhesive layer 13 and the cover glass 15. At this time, as the swing arm 116 rotates, the cover glass 15 is drawn out from the drawing portion 112 of the table 111 and then transferred to the subsequent step. The swing arm portion 116 is drawn into the lead-out portion 112 again after the cover glass 15 is transferred to a subsequent process. And the preprocessing process of the other display unit 10 is performed again.
The present invention has been described with reference to the embodiments shown in the drawings, which are illustrative only, and it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted therefor.
