Description

Bonding device for window

The present invention relates to a window bonding apparatus, and more particularly, to a window bonding apparatus that enables precise bonding between a window and a panel by allowing positional alignment in a state in which a panel is supplied and in a state before bonding, respectively.

In recent years, as society enters the era of full-scale information, the field of display processing and displaying a large amount of information has rapidly developed, and in response to this, various flat panel display devices have been developed and are in the spotlight.

Specific examples of such a flat panel display device include a liquid crystal display device (LCD), a plasma display panel device (PDP), a field emission display device (FED), and an electroluminescent display device. (Electroluminescence Display device: ELD), organic light emitting diodes (OLED), etc. These flat panel display devices show excellent performance in thinner, lighter, and low power consumption. ) Is rapidly being replaced.

Meanwhile, in recent years, a curved display device is applied to a portable wireless telephone, which allows the user to feel more immersive and more realistic, so that the user feels comfortable.

Since such curved display devices do not have a bezel formed on a curved portion, the image can be realized wider, and the use of curved windows is increasing, and a panel made of a flexible material is attached to the inner side of the window.

The curved window as above has the advantage of space utilization, interior and design by forming at least one curved shape around the outer circumference of a rectangular shape, and above all, because the bezel can be removed, the screen becomes larger. The user's gaze is fixed, thereby increasing the degree of immersion.

In the conventional Korean Patent Publication No. 10-2018-0056004, a first jig for fixing a window; And a second jig including a shape pad facing the first jig, wherein the shape pad is recessed inward from a convex upper surface toward the first jig, a side surface surrounding the upper surface, and the side surface. A laminate apparatus including a cutout pattern extending toward one jig is disclosed.

However, in the above laminate device, the window and the panel are bonded to each other through elastic deformation of the shape pad by pressing force, but when the shape pad is restored to its initial shape, the top of the convex upper surface maintains a set distance with the window. There is a problem that is difficult to do.

In other words, when the shape pad is restored, the position of the highest point of the upper surface is changed in micro units. In this case, the highest point of the upper surface of the shape pad does not coincide with the center of the arch-shaped panel during bonding, so the pressing force is uniform. There is a fatal problem in that the alignment between the panel and the window is misaligned due to the improper transmission, resulting in a bonding failure.

Moreover, in the case of the shape pad, as it is fixed to the stage by an operator, there is a limit to allowing the top point of the upper surface to be accurately set up to the micro unit.

In addition, in the case of the above laminate device, when the window edge is formed with a bent surface of at least 90 degrees, the upper surface of the periphery of the panel during the bonding process is formed at the lower end of the window edge because the bonding is inevitable in a state in which the panel is bent. The OCA bonding layer deposited on the surface of the panel is pushed by the friction, causing a fatal problem of product reliability. In other words, there is no separate means for bending the panel in order to prevent chafing of the upper surface of the circumference of the panel.

It is a process chart showing the process of bonding the window and the panel through.

As shown in Figs. 1 to 8, the window bonding apparatus 100 of the present invention includes a window jig 10 having a seating groove 11 on which a window W is seated; An elevating plate 20 disposed below the window jig 10 and installed to be elevating to attach the panel F to the window W; A pressure pad 30 fixed to the upper surface of the lifting plate 20 and adhering to the window W through elastic deformation while pressing the panel F toward the window W by the elevation of the lifting plate 20; The panel (F) is supported between the window jig (10) and the pressing pad (30), and the end of the panel (F) is bent and pressed while the panel (F) is in close contact with the surface of the pressing pad (30) before bonding. At least two forming units 40 for forming in close contact with the circumferential surface 32 of the pad 30; A first alignment driver 50 supporting the lifting plate 20 and aligning the panel F supplied to the upper portion of the pressure pad 30 and the pressure pad 30; And a second alignment driving unit 55 supporting the molding unit 40 and the first alignment driving unit 50 and aligning the panel F formed in close contact with the pressing pad 30 with the window W. ); consists of.

The window bonding apparatus 100 of the present invention is to allow bonding of a window W and a panel F having an edge formed of a bent surface W1 of at least 90 degrees on both sides or slopes facing each other, this embodiment In the example, the edge of the bent surface W1 is formed on both sides facing each other, and the bent surface W1 is 90 degrees or more.

Prior to the description, the greatest feature of the present invention is that even if the position of the highest point of the upper surface of the pressure pad 30 is varied, the panel F that is in close contact with the pressure pad 30 is subjected to an alignment process, respectively, before and after contact, It is to fundamentally block the OCA bonding layer from being damaged by the upper surface of the circumference of the panel (F) being rubbed against the edge of the window (W) when bonding through the molding of the panel (F).

In addition, the above configuration and configurations to be described later are connected to a control device (not shown), and are driven according to information previously set in the control device.

In the window bonding apparatus 100 of the present invention, as shown in FIG. 1, a window jig 10 is disposed on the upper side of the drawing, and an elevating plate 20 is disposed below the window jig 10, and the elevating plate 20 The pressing pad 30 is seated and fixed, the molding units 40 are disposed on both sides of the lifting plate 20, and the lifting plate 20 and the molding unit 40 are fixed to the second alignment driving part 55. The structure is showing.

The window jig 10 supports the window W, which is the target of the panel F, and is recessed inward on the lower side of the drawing facing the pressure pad 30 so that the window W is seated. (11) is formed.

At this time, the overall shape of the seating groove 11 will, of course, correspond to the shape of the supported window (W).

In addition, it goes without saying that the window jig 10 has a structure connected to a separate lifting device (not shown) so that it can be lifted up and down during bonding.

The elevating plate 20 is disposed under the window jig 10 while being fixed to the second alignment driver 55 to be described later, and a plurality of elevating rods 21 are provided on the lower surface of the elevating plate 20, and These lifting rods 21 are connected to a separate lifting device (not shown) and are installed to be able to move up and down.

The upper surface of the lifting plate 20 is formed in the shape of a flat plate so that the pressing pad 30 to be described later can be fixed, and the area is preferably at least corresponding to the area of the pressing pad 30.

Therefore, the lifting plate 20 is to lift the pressure panel (F) to be described later in order to attach the panel (F) to the window (W) supported by the window jig (10) so as to rise, and more precisely, the lifting plate It is to allow the elastic pressing force of the pressing pad 30 to be applied to the panel (F) side by rising of (20).

A first alignment driving unit 50 is provided below the lifting plate 20, and the first alignment driving unit 50 will be described later.

The pressure pad 30 maintains a rectangular shape as a whole, and while being fixed on the upper surface of the lifting plate 20, the panel toward the window W side supported by the window jig 10 while rising by the lifting plate 20 Pressing (F) allows the window (W) and panel (F) to be bonded together.

To this end, the upper surface 31 of the pressing pad 30 is formed to be curved so that gradual bonding is performed from the center of the longitudinal direction of the panel F to the edge direction of the window W during bonding, and the circumferential surface 32 Is formed with an inclination of at least 90 degrees so that the end of the panel F is bent at least 90 degrees or more by the molding units 40 to be described later to be in close contact with the circumferential surface 32.

In other words, the upper surface 31 of the pressure pad 30 forms a convex top point in the center in the longitudinal direction, and maintains the shape of a bow shape that gradually downwards toward both circumferential directions.

Here, forming the circumferential surface 32 of the pressing pad 30 to be at least 90 degrees or more means that the end of the panel F is in close contact with the circumferential surface 32, so that the panel that enters the inside of the window W upon bonding This is to prevent the end of (F) from being rubbed against the lower end of the edge of the window (W).

In addition, the end of the upper surface 31 connecting the upper surface 31 and the circumferential surface 32 of the pressing pad 30 is preferably formed in a predetermined round 33, which is the molding units 40 This is to prevent sudden bending by allowing the panel F to be bent along the round 33 when the end of the panel F is bent.

And, the area of the pressing pad 30 may correspond to the area of the seating groove 11 of the window jig 10 or may be formed slightly smaller than the area of the seating groove 11, which is a bent surface ( When W1) is 90 degrees, the bent surface (W1) is directly supported by the seating groove (11), so that the end of the panel (F) to be bonded is bent by more than 90 degrees to be accommodated inside the window (W). Because it can.

If the end of the panel (F) is not bent and the pad is bonded to form a curved surface as in the prior art, bonding is smoothly performed in the plane section of the window (W), but bubbles are completely formed in the bent surface (W1). There is a problem that cannot be pulled out, and in addition, the OCA adhesive layer is damaged by being rubbed against the lower end of the bent surface W1 while the end side of the panel F enters the inside of the bent surface W1.

On the other hand, the pressing pad 30 is of course made of a material that can be elastically deformable so that a gradual pressing force is applied from the center of the panel F to the edge direction of the window W when the window W and the panel F are bonded together. As for the material, silicone may be the most ideal.

In the present embodiment, the inclination of the circumferential surface 32 indicated in the drawing is 90 degrees or more, but the inclination angle of the circumferential surface 32 is not limited as long as friction of the end of the pad can be prevented during bonding.

The molding unit 40 is disposed on both sides of the pressing pad 30 as shown in FIG. 1 to support the panel F supplied between the window jig 10 and the pressing pad 30, and the panel F before bonding. While the central region is in close contact with the upper surface 31 of the pressing pad 30, the end of the panel F is bent to form in close contact with the circumferential surface 32 of at least 90 degrees or more of the pressing pad 30.

At this time, if the edges of the widow to be bonded face each other as shown in FIG. 1, two forming units 40 will be installed, and if the edges of the window W are formed in all directions, four will be installed.

The molding unit 40 is installed in the direction of the pressure pad 30 so as to be movable in the direction of the lifting plate 20 on the upper part of the second alignment driving part 55, and the slider 41 It is a clamp 42 that clamps and expands and contracts the molded sheet 70 to which the panel F is attached, and a rod-shaped elastic pressing member that is installed to be elevating and descending on the slider 41 and rotates with the clamp 42 interposed therebetween. It consists of a pushing block 44, which is connected to 43.

Here, the molding sheet 70 is a flexible material, and the panel F is adhered to the center as shown in FIG. 3, and wing pieces 71 extending to a predetermined length so that it can be clamped to the clamp 42 are formed on both sides. Has been.

At this time, the starting point of the wing piece 71 is a portion where bending begins, and both ends of the bonded panel F are in a state in which the starting point of the wing piece 71 is invaded, respectively.

In this case, when the wing piece 71 is bent, the end of the panel F is also bent (see FIG. 5).

The slider 41 is fixed to the second alignment driving unit 55, which will be described later, and is connected to a driving means (not shown) to move on a rail, and moves left and right in the horizontal direction according to the control of the control device. .

The clamp 42 moves in opposite directions facing each other while clamping the ends of the wing pieces 71 on both sides of the molding sheet 70, and moves up and down in a state in which the molding sheet 70 is stretched and contracted taut.

The pushing block 44 is fixed to the slider 41 as shown in Figs. 1 and 2 and is installed so as to be lifted up and down, and as shown in Fig. 2, a rod-shaped elastic pressing member ( 43) is in an interconnected state.

At this time, support pieces having a predetermined length are provided at both ends of the elastic member in the longitudinal direction so that the elastic pressing member 43 is spaced apart from the pushing block 44 by a predetermined distance, and the ends of the supporting pieces are tensioned, not shown. It is elastically supported by the pushing block 44 by the device.

In this case, the elastic pressing member 43 may correspond at least to the length of the pressing pad 30 or may be formed to be longer.

Accordingly, the elastic pressing member 43 elastically supports the molding sheet 70 so that the end of the panel F can be bent while receiving the elasticity of the support piece (see FIG. 5).

In addition, the lifting of the clamp 42 and the pushing block 44 may be driven through a cylinder or a driving motor.

The first alignment drive unit 50 supports the lifting plate 20 on which the pressure pad 30 is fixed so as to be able to move up and down, and the flat panel F supplied to the upper portion of the pressure pad 30 for the bonding process and The pressure pad 30 is aligned.

In the first alignment drive unit 50, a plurality of driving cylinders (not shown) for moving or rotating the lifting plate 20 in the X-axis, Y-axis and θ directions while supporting the lifting plate 20 as shown in FIG. Si) is installed, and the center of the pressure pad 30 is aligned with the center position of the supplied panel F through the driving of this driving cylinder.

That is, the lifting plate 20 is moved in the X-axis, Y-axis and θ direction by the driving of the first alignment driver 50, and the center of the pressure pad 30 fixed to the upper surface and the center position of the supplied panel F This is to ensure that the first alignment is achieved.

To this end, the position of the panel F is photographed while moving between the window jig 10 and the pressure pad 30 for alignment of the supplied panel F between the window jig 10 and the pressure pad 30. A vision 60 is placed (see Fig. 3).

The vision 60 photographs the position of the panel F and transmits the photographed image to the control device. In the control device, the transmitted panel (F) image and the previously input panel (F) and pressure pad (30) The standard position data value of) is compared and analyzed, and the center of the pressure pad 30 and the panel F are aligned to match while controlling the first alignment driver 50 based on this data value.

The second alignment driving unit 55 supports the lifting plate 20, the forming unit 40, and the first alignment driving unit 50, and a pressure pad 30 before bonding of the panel (F) and the window (W) The panel (F) formed in close contact with the panel (F) is aligned to match the panel (F) with the window (W).

In the second alignment driving unit 55, the forming unit 40 and the first alignment driving unit 50 are X-axis while simultaneously supporting the forming unit 40 and the first alignment driving unit 50 as shown in FIG. 1. , A plurality of driving cylinders (not shown) are installed to move or rotate together in the Y-axis and the θ direction, and the center position of the panel (F) molded to be in close contact with the pressure pad 30 through the driving of these driving cylinders. Is aligned with the center position of the window (W).

In other words, the second alignment driving unit 55 has the forming unit 40 and the first alignment driving unit 50 in a state in which the panel F is formed in close contact with the pressing pad 30 through the forming unit 40. At the same time, it is moved in the X-axis, Y-axis and θ directions to align the center of the panel F close to the pressing pad 30 and the center of the window (see FIG. 6).

In this case, the second alignment driving unit 55 is preferably manufactured to withstand a high load so as to support the molding unit 40 and the first alignment driving unit 50.

In addition, between the window jig 10 and the pressing pad 30, the vision 60 for photographing the position of the panel F for aligning the panel F in close contact with the pressing pad 30 is moved.

Vision 60 transmits the photographed image of the panel (F) in close contact with the pressure pad 30 to the control device, and in the control device, the transmitted panel (F) image and the previously input panel (F) are standard. The position data value is compared and analyzed, and the center of the panel (F) in close contact with the pressure pad (30) is aligned to match the center of the window (W) while controlling the second alignment drive unit 55 based on this data value. .

The alignment method of the panel F through the first alignment driving unit 50 and the second alignment driving unit 55 described in the present embodiment is not necessarily limited because various methods can be applied.

Hereinafter, a process in which the window W and the panel F are bonded using the window bonding apparatus 100 according to the present invention will be described with reference to the accompanying drawings.

3 to 8 are process diagrams showing a process in which the window W and the panel F are bonded through the window bonding apparatus 100 according to the present invention.

First, as shown in FIG. 3, the window W is seated in the seating groove 11 under the window jig 10. At this time, a plurality of vacuum holes (not shown) are formed on the inner surface of the seating groove 11 to allow the window W to be supported by the seating groove 11 by adsorbing the surface of the received window W.

At this time, the window jig 10 is in a state in which the window W is supported and is disposed on the upper side as shown in FIG. 3.

In addition, when the molding sheet 70 to which the panel F is adhered is supplied to the upper side of the pressing pad 30, the clamps 42 clamp the wing piece 71 of the supplied molding sheet 70 as shown in FIG. 3. do.

Thereafter, the clamps 42 tighten the molded sheet 70 through a set distance movement of the slider 41 in the direction of the arrow while clamping each wing piece 71. At this time, the panel F adhered to the molding sheet 70 is also stretched and contracted in tension.

When the clamping of the panel F is completed, the vision 60 enters between the window jig 10 and the pressure pad 30 as shown in FIG. 3 and the position of the panel F supported by the clamp 42 Is taken and returns to the initial state.

The image captured through the vision 60 is transmitted to the control device, and the control device compares and analyzes the standard position data values of the previously input panel F and the pressure pad 30, and based on this, the first alignment drive unit 50 ).

At this time, as the first alignment drive unit 50 moves the lifting plate 20 in the X-axis, Y-axis and θ directions as shown in the arrow direction shown in FIG. 3, a pressure pad fixed to the lifting plate 20 (30) is also interlocked, and in this process, the center of the pressure pad 30 is aligned with the center of the panel (F).

Thereafter, the vision 60 may re-image the panel F to check the alignment state of the aligned pressure pad 30 and the panel F.

Thereafter, when the alignment of the pressing pad 30 and the panel F is completed, the pressing blocks 44 and the clamps 42 descend in the direction of the arrow in FIG. 3 while the molding sheet 70 is clamped. The sheet 70 is positioned adjacent to the upper surface of the pressing pad 30.

At this time, the descending of the pushing blocks 44 is made until the elastic pressing members 43 are positioned on the upper surface of each wing piece 71 of the forming sheet 70 as shown in FIG. 4.

When the molding sheet 70 is disposed at the set position, the lifting plate 20 rises as shown in FIG. 5, and thus the pressure pad 30 also rises in the direction of the arrow in the drawing.

The rising pressure pad 30 makes contact with the center of the molding sheet 70, and pushes the center of the molding sheet 70 upward in the drawing through the continued rise.

At this time, the elastic pressing members 43 of the pushing block 44 move in the direction of the circumferential surface 32 of the pressing pad 30 by moving the slider 41 in the direction of the arrow at the same time as the pressing pad 30 is raised. While bending the wing pieces 71 of the molding sheet 70 in the downward direction on the drawing, they are brought into close contact with the circumferential surface 32.

At this time, in close contact with the circumferential surface 32 of the wing pieces 71, when the pressing pad 30 is raised, the elastic pressing members 43 push the wing pieces 71 of the forming sheet 70 to the pressing pad 30. It is made naturally by pushing while receiving elasticity in the direction of the circumferential surface 32, and in addition, the elastic pressing member 43 is in a state in which the wing piece 71 is continuously pushed as it is elastically supported by the pushing block 44. Will be maintained.

Therefore, the panel (F) is bent together with the circumference of the panel (F) in the process of bending the wing piece 71 of the molding sheet 70, so the upper surface 31 and the circumferential surface 32 of the pressing pad 30 ) Is molded in a state that is completely in close contact with each other.

In addition, the bending of the end of the panel (F) maintains a stable bending state because it is bent along the round 33 of the circumferential end of the pressing pad 30 when the wing piece 71 of the molding sheet 70 is bent.

And, since the elastic pressing member 43 is in close contact with the circumferential surface 32 formed at 90 degrees or more of the pressing pad 30, the blade piece 71 of the molding sheet 70, the end of the panel (F) is also While being bent together with the reorganization 71, it is in close contact with the circumferential surface 32 as shown in FIG. 5.

In this case, since the end of the panel F is bent by 90 degrees or more, contact with the lower end of the edge of the window W is prevented during bonding.

When the molding of the panel F is completed, the vision 60 enters between the window jig 10 and the pressure pad 30 as shown in FIG. 6 to photograph the position of the molded panel F on the pressure pad 30. It returns to the initial state.

The image captured through the vision 60 is transmitted to the control device, and the control device drives the second alignment driver 55 based on the comparison and analysis of the previously input standard position data value of the panel F.

At this time, the second alignment driving unit 55 moves the first alignment driving unit 50 and the molding unit 40 together in the X-axis, Y-axis and θ direction as shown in the arrow direction shown in FIG. Match the center position of the panel (F) molded to 30) with the center of the window (W) as shown in a dashed-dotted line.

Thereafter, the vision 60 may re-photograph the panel F to check the alignment state of the aligned panel F and the window W.

When the alignment of the panel F is completed, the upper window jig 10 is lowered to the set position as shown in FIG. 7, and at the same time, the lifting plate 20 is also raised and the pressing pad 30 is raised.

When the pressure pad 30 starts to rise, the center of the panel F adhered to the molding sheet 70 by the highest point of the upper surface 31 of the pressure pad 30 as shown in FIG. 7 is first the window (W). Bonding is achieved by making contact with.

Thereafter, the panel (F) gradually increases the contact area from the center of the panel (F) toward both sides (edge direction) by the continuous rise of the pressure pad (30), and is finally accommodated inside the window (W). The pressing force of the pressing pad 30 is transmitted to the end of the panel F, and the end of the panel F is in close contact with the bent surface W1 of the edge of the window W as shown in FIG. ) To complete the cementation.

Thereafter, the window W to which the panel F is attached moves the window W to the post process while rising upward on the drawing in the state of FIG. 8, and the lifting plate 20 and the forming unit 40 are initially It returns to the state, and the above bonding process is performed repeatedly.

As described so far, the window bonding device of the present invention first presses the supplied panel even if the position of the top of the pressure pad is slightly changed due to the incomplete fixing position of the pressure pad or the state of elastic deformation after bonding. By aligning with the pad and in close contact with the pressure pad, and secondly aligning the panel in close contact with the pressure pad with the window, there is an excellent effect of precisely bonding the window and the panel.

In addition, when the edge of the window is formed with a bent surface of at least 90 degrees, the molding units bend the end of the panel while pressing the panel in close contact with the pressing pad to form it in close contact with the circumferential surface of the pressing pad. The structural effect that guarantees the reliability of the finished product is also excellent because the scratch on the upper surface is fundamentally blocked.

In the above, the window bonding apparatus of the present invention has been described with reference to a preferred embodiment and the accompanying drawings, but this is not intended to limit the technical scope of the present invention, but only to aid understanding of the invention.
