Description

[0001] The present invention relates to a panel edge adhesive resin curing apparatus,

The present invention relates to an adhesive curing apparatus, and more particularly, to a panel edge adhesive curing apparatus capable of selectively curing an edge portion of an adhesive applied to a panel when a touch panel is manufactured by attaching a display panel and a touch assembly will be.

Due to the popularization of smartphones and tablet PCs, the demand for touch-enabled display panels is surging. Generally, a touchable display, that is, a touch panel is manufactured by attaching a touch assembly, which is a panel having a touch function, to a general display panel such as an LCD.

The adhesion of the display panel and the touch assembly can be achieved by attaching an OCA tape along the rim of the bezel on the upper surface of the display panel and attaching the touch assembly thereon . However, if the panel and the touch assembly are cemented together using the OCA tape as described above, the thickness of the OCA tape becomes thick and the thickness of the entire display device becomes thick. In addition, an air gap is formed on the center side without the OCA tape The sharpness is lowered and the wide viewing angle is narrowed, resulting in poor image quality.

In recent years, various types of OCR (Optically Clear Resin) adhesives including Loctite Liquid Optically Clear Adhesives (LOCA) have been applied evenly over the entire upper surface of the panel and the touch assembly is attached thereon. Thereby preventing thickening and deterioration of image quality.

When the display panel and the touch assembly are adhered using the adhesive resin, only the adhesive applied to the four edges of the panel is cured prior to adhering to form a kind of dam to prevent the inner adhesive from flowing or overflowing And it is necessary to cure all remaining adhesive that has not been cured after the cementation.

Korean Patent Laid-Open Publication No. 10-2012-0096141 discloses a method in which only an adhesive is applied only to the edge portion and the inner side of the panel in a dot manner and at the same time, the UV lamp is moved along the edge portion of the panel to harden the edge, An apparatus for curing an entire adhesive is provided. However, according to such a conventional apparatus, the configuration of the driving unit for moving the UV lamp is complicated as a method of curing while moving the UV lamp along the edge portion of the panel, and the degree of curing varies depending on the deviation of the moving speed, There is a disadvantage that the width of the light screen is not uniform due to the flow of the UV lamp.

Korean Patent No. 10-1331878 discloses an adhesive curing device having a UV lamp unit and a UV mask for shielding the central portion of the panel so that ultraviolet rays emitted from the UV lamp unit are irradiated only to the four edges of the panel. However, when the size of the UV-cured portion is changed according to the size of the panel, there is a need to change the size of the mask film.

Korean Patent Publication No. 10-2012-0096141 Korean Patent No. 10-1331878

Accordingly, the ramp module 510 is moved up and down by the operation of the lifting cylinder 531. A first LM guide 537 is provided between the lamp module bracket 514 and the vertical plate 533 on the rear side for a stable guide of the lamp module 510. The lifting cylinder 531 is mounted to the lifting cylinder supporting bracket 532 and the second lifting guide 536 is installed between the lifting cylinder supporting bracket 532 and the vertical plate 533. [ A ball screw 534 having a rotary knob 535 is disposed on the rear side of the vertical plate 533 and a side to which the rotary knob 535 is coupled is coupled to the vertical plate 533 with a separate bracket, The nut block 538 is screwed into the lifting cylinder support bracket 532 through the through hole 533a formed at the center of the vertical plate 533. [ The vertical plate 533 is fixedly coupled to a separate frame or bracket (not shown).

A rotation aligning means 620 for rotating the panel seating plate 640 by 90 degrees is provided below the panel seating plate 610. The rotary alignment means 620 is preferably a DD motor and is supported by a support plate 622 below.

The rotation aligning means 620 and the panel seating plate 610 disposed thereon are horizontally moved and moved in the X axis direction on the lower side of the rotational alignment means 620 and more specifically on the lower side of the support plate 622, The X-axis direction to align is provided with the transmission array means 630. The X-axis direction transmitting section 630 includes an X-axis direction feeding motor 632 and a ball screw 634. [ The nut block 636 which is disposed in the X-axis direction and is rotated by the X-axis direction feed motor 632 and screwed to the ball screw 634 is inserted into the lower portion of the support plate 622 . The X axis direction feed motor 632 and the ball screw 634 are installed on the base plate 638.

The Y-axis direction aligning means 640 includes a Y-axis direction aligning motor 642 and a ball screw 644 and a nut block (not shown) screwed to the ball screw 644 is mounted on the base plate 638 As shown in Fig. The Y-axis direction alignment motor 642 and the ball screw 644 are installed on a separate table (not shown).

When the panel having the adhesive agent applied on its upper surface is placed on the panel seating plate 610, the X-axis direction is horizontally moved in the X-axis direction by the transmission array unit 630 and disposed on the lower side of the lamp module 510. Then, according to the operation of the Y-axis direction aligning means 640, it is aligned with the Y-axis directional orientation of the lamp module 510. Such alignment can be performed by using a separate sensor or by a conventional vision alignment method or the like.

When the alignment is completed, as shown in FIG. 3, the lamp module 510 is lowered by the lamp module elevating means 530 to harden the adhesive material at one side edge portion of the panel. Then, the lamp module 510 is raised, and the panel seating plate 610 is rotated by 90 degrees in accordance with the operation of the DD motor in the meantime. The lamp module 510 is then lowered again to harden the other edge portion of the panel. By repeating these operations, the adhesive material at the four edge portions of the panel is cured, and the finished panel is subjected to a panel laminating process, which is a post-process, to produce the finished touch panel.
