Description
Technical Field
The present invention relates to a display member manufacturing apparatus and a display member manufacturing method, and more particularly, to a display member manufacturing apparatus and a display member manufacturing method capable of preventing a screen display member from being damaged, preventing a bubble layer from being formed between the screen display member and a cover glass, and preventing a pressing mark from being generated on the screen display member.
Background
Generally, a display unit is provided in a mobile device such as a smart phone or a tablet computer. The display section includes a screen display section and a cover glass. A cover glass (cover glass) is attached to the outer side surface of the screen display member through an optical adhesive layer. The screen display unit is configured by laminating a thin film transistor, a photodiode layer, and a polarizing layer, or by a liquid crystal, a color filter, and a polarizing layer. The screen display member has a circuit board laminated thereon.
In the case of bonding the screen display part to the cover glass, the bonding press part presses the cover glass and the screen display part in a high-weight manner. As the cover glass and the picture display section are pressurized, bubbles between the cover glass and the picture display section are discharged to the outside.
However, since the electronic components, the electrodes, the solder balls, and the like protrude from the surface of the screen display member in the conventional circuit board, it is difficult to apply a high-weight pressure in consideration of damage to the electronic components, the electrodes, the solder balls, and the like when the cover glass is bonded to the screen display member.
Further, since the position of the circuit board on the screen display unit, the positions and heights of the electronic components and the solder balls, and the like vary in accordance with the type or model of the mobile device, it is difficult to form the step portion in the table portion in accordance with the type or model of the mobile device.
Further, when the cover glass and the screen display member are joined, the pressing force applied to each part of the screen display member is different due to the difference in level between the elements, the solder balls, or the like, and therefore the screen display member may leave pressing traces, which may cause a poor appearance.
Korean patent laid-open publication No. 10-1662584 (granted 2016.09.28, title of the invention: curved surface molding apparatus of cover glass for touch screen and method thereof) discloses the background art of the present invention.

Referring to fig. 1 to 6, a display member manufacturing apparatus according to an embodiment of the present invention includes a bonding stamping part 31, a bonding stage part 33(bonding stage part), and a damage prevention part 36.
The bonding press 31 presses the cover glass 11 and the screen display unit 13. The bonding punch 31 can be pressed with a pressing force of about 1 ton (ton) to discharge bubbles between the screen display part 13 and the cover glass 11.
The screen display section 13 is placed on the bonding stage section 33, and the cover glass 11 is laminated on the screen display section 13. An optical adhesive layer 17 is disposed between the cover glass 11 and the screen display member 13. The optical adhesive layer 17 may be adhered to an edge portion of the lower surface of the cover glass 11 or an edge portion of the upper surface of the screen display member 13.
The screen display unit 13 includes a circuit board 14, and the circuit board 14 has a projection 15 such as an electronic component, an electrode, and a solder ball. The circuit board 14 is laminated on the screen display unit 13 in various shapes. The circuit board 14 can have the protruding portion 15 formed thereon at various positions and heights.
As the screen Display unit 13, Organic Light Emitting Diodes (OLEDs), Quantum dot Light Emitting Diodes (QLEDs), Liquid Crystal Displays (LCDs), and the like can be applied.
The engaging table portion 33 is disposed opposite to the engaging punch portion 31, and is formed with a placing portion 34 for placing the screen display member 13, and the engaging table portion 33 is formed with an accommodating groove portion 35 in such a manner as to be opposite to the protrusion portion 15 of the screen display member 13. The housing groove 35 may be formed in the same shape as the circuit board 14 of the screen display unit 13. For example, when the circuit substrate 14 is formed
In the case of the shape, the housing groove 35 may be formed
And (4) shape.
The placing portion 34 of the engaging land portion 33 is formed flat. The land portion 33 has a rigidity of about 60 to 100N/mm. Therefore, when the joining punch 31 is pressed, the joining table portion 33 supports the screen display member 13 to prevent the screen display member 13 from being bent. The joint table portion 33 may be formed of a synthetic resin material such as a silicon or urethane (urethane) material.
The damage prevention portion 36 is disposed in the housing groove portion 35, and moves upward of the housing groove portion 35 as the pressure is applied by the protrusion portion 15 of the screen display member 13, thereby supporting an edge portion of the protrusion portion 15 (a lower surface of the screen display member 13). At this time, the protrusion 15 is embedded in the damage prevention portion 36. The damage preventing portion 36 is formed of a flexible resin such as silicon so as to be deformed by a pressing force of the protrusion portion 15. The damage prevention section 36 has a rigidity of about 1 to 30N/mm.
The damage preventing portion 36 supports the protruding portion 15 and the edge portion thereof, so that the entire lower surface of the screen display member 13 is supported with uniform pressure by joining the table portion 33 and the damage preventing portion 36. Therefore, when the bonding punch 31 presses the cover glass 11, the screen display member 13 and the cover glass 11 are pressed with uniform pressure as a whole, and therefore, a bubble layer can be prevented from being formed between the screen display member 13 and the cover glass 11. Further, since the damage preventing portion 36 moves upward of the protrusion 15 and the protrusion 15 is embedded in the damage preventing portion 36, the protrusion 15 can be prevented from being damaged by the pressing force of the joining punch 31. Further, since the screen display member 13 can be prevented from being pressed by the opposing force of the projection 15, appearance defects of the display member 10 can be prevented.
Further, the damage preventing portion 36 is variously deformed according to the shape and height of the protrusion portion 15, so that it is not necessary to form a stepped groove matching the shape and position of the protrusion portion 15 in the joint table portion 33 according to the kind or shape of the display member 10.
The housing groove 35 is provided opposite the circuit board 14 on which the protrusion 15 is mounted, and the damage prevention portion 36 is disposed in the housing groove 35 so as to face the circuit board 14. Since the damage preventing portion 36 is disposed to face the circuit board 14, the damage preventing portion 36 can be variously deformed depending on the position of the protruding portion 15 such as an electronic component, an electrode, and a solder ball in the circuit board 14. Therefore, the screen display member 13 is pressurized with a uniform pressure as a whole, and therefore, the projection 15 can be prevented from being damaged or the screen display member 13 can be prevented from being pressed. Further, since a uniform pressure is applied to the entire screen display unit 13, a bubble layer can be prevented from being formed between the screen display unit 13 and the cover glass 11.
The depth of the housing groove portion 35 is formed to be deeper than the height of the protrusion portion 15, and the upper surface of the damage prevention portion 36 is arranged to be lower than the upper surface of the land portion 33. Therefore, the damage prevention portion 36 moves upward of the housing groove portion 35 due to the pressurization of the protrusion portion 15, and can support the lower surface of the screen display member 13.
A suction port portion 34a is formed in the bonding stage portion 33 so as to vacuum-suck the screen display member 13. Since the suction port portion 34a vacuum-sucks the screen display member 13, the screen display member 13 can be prevented from being positionally changed in the bonding stage portion 33 when the screen display member 13 is pressurized.
A method of manufacturing the display member according to an embodiment of the present invention configured as described above will be described.
Fig. 7 is a flowchart illustrating a manufacturing method of a display member according to an embodiment of the present invention, fig. 8 is a diagram illustrating a process of bonding an optical adhesive layer to a cover glass in the manufacturing method of a display member according to an embodiment of the present invention, and fig. 9 is a diagram illustrating a process of bonding a cover glass and a screen display member in the manufacturing method of a display member according to an embodiment of the present invention.
Referring to fig. 7 to 9, the cover glass 11 is placed on the placing stage part 21 (S11). At this time, the cover glass 11 is placed on the placing table 21 so that the bonding surface faces upward.
The first release film 17a is removed from the optical attachment layer 17 (S12). At this time, the first release film 17a and the second release film 17b are attached to both surfaces of the optical adhesive layer 17, respectively, and the first release film 17a is removed from the optical adhesive layer 17, while the second release film 17b is not removed from the optical adhesive layer 17.
The optical adhesive layer 17 is attached to the cover glass 11 (S13). The cover glass 11 is loaded in the vacuum chamber 25, and the optical adhesive layer 17 is bonded to the cover glass 11 by vacuum and pressure (S14, S15). At this time, the second release film 17b is positioned on the upper surface of the optical adhesive layer 17, and the adhesive pressing portion 23 presses the optical adhesive layer 17 to be bonded to the cover glass 11. After the optical adhesive layer 17 is bonded to the cover glass 11, the cover glass 11 is taken out from the vacuum chamber 25.
The screen display member 13 is placed on the joint table portion 33 such that the projection portion 15 of the screen display member 13 faces the damage preventing portion 36 (S16).
The second release film 17b is removed from the optical adhesive layer 17 of the cover glass 11 (S17). The cover glass 11 to which the optical adhesive layer 17 is attached is laminated on the upper side of the screen display member 13.
The suction port portion 34a of the bonding stage portion 33 sucks the screen display member 13 to the bonding stage portion 33 (S18). Since the suction port portion 34a vacuum-sucks the screen display member 13, the screen display member 13 can be prevented from being positionally changed in the bonding stage portion 33.
The cover glass 11 and the screen display unit 13 are loaded in the bonding chamber (S19). The inside of the bonding chamber is formed with a vacuum or a low pressure close to the vacuum.
The cover glass 11 and the picture display section 13 are joined (S20). At this time, the cover glass 11 and the screen display member 13 are pressurized, and the damage prevention portion 36 moves upward of the storage groove portion 35 by the pressurizing force of the protrusion portion 15 to support the edge portion of the protrusion portion 15.
The damage preventing portion 36 supports the protruding portion 15 and the edge portion thereof, so that the entire lower surface of the screen display member 13 is supported with uniform pressure by joining the table portion 33 and the damage preventing portion 36. Therefore, when the bonding punch 31 presses the cover glass 11, the screen display member 13 and the cover glass 11 are pressed with uniform pressure as a whole, and therefore, a bubble layer can be prevented from being formed between the screen display member 13 and the cover glass 11. Further, since the damage preventing portion 36 moves upward of the protrusion 15 and the protrusion 15 is embedded in the damage preventing portion 36, the protrusion 15 can be prevented from being damaged by the pressing force of the joining punch 31. Further, since the force opposing the projection 15 is hardly applied to the screen display member 13, the screen display member 13 can be prevented from being pressed. Therefore, appearance defects of the display member 10 can be prevented from occurring.
Since the damage preventing portion 36 is disposed to face the circuit board 14, the damage preventing portion 36 can be variously deformed depending on the position of the protruding portion 15 such as an electronic component, an electrode, and a solder ball in the circuit board 14. Therefore, the screen display member 13 is pressurized with a uniform pressure as a whole, and the projection 15 can be prevented from being damaged or the screen display member 13 can be prevented from being pressed. Further, since a uniform pressure is applied to the entire screen display unit 13, a bubble layer can be prevented from being formed between the screen display unit 13 and the cover glass 11.
The depth of the housing groove portion 35 is formed to be deeper than the height of the protrusion portion 15, and the upper surface of the damage prevention portion 36 is arranged to be lower than the upper surface of the land portion 33. Therefore, the damage prevention portion 36 moves upward of the housing groove portion 35 due to the pressurization of the protrusion portion 15, and can support the lower surface of the screen display member 13.
The present invention has been described with reference to the embodiments shown in the drawings, which are intended to be illustrative only, and various modifications and equivalent other embodiments will be apparent to those skilled in the art.
Therefore, the true technical scope of the present invention should be defined based on the claims.
