Generally, a polarizing film is attached to a display panel to determine optical characteristics of each display.

The polarizing film refers to a film that has a polarizing function that allows light in a certain direction to pass therethrough but reflects the remaining light. And roles are as follows.

In other words, the polarizing film separates incident light into two polarized light components orthogonal to each other, and passes only one of the polarized light components to absorb or disperse the other components. The polarizing film absorbs or disperses the other components, and supports the support TAC (Triacetyl-cellulose) Is used on both sides of the polarizing medium, and the adhesive layer is used to adhere the polarizing film to the protective film. On the upper surface, an anti-glare (AG) or anti-reflection (AR) coating layer and a protective film are provided.

For example, light emitted from the backlight of an LCD module has the same probability of vibration direction in all directions. In other words, the polarizing film transmits only the light vibrating in the same direction as the polarization axis among the light, and the light vibrating in the other direction is absorbed or reflected by using a suitable medium, thereby making light oscillating in a specific direction.

Since the polarization axes of the polarizing films are attached to both sides of the liquid crystal cell such that the polarizing axes thereof are orthogonal or parallel to each other, the strength of the transmitted light is adjusted according to the degree of rotation of the polarization axis during passing through the liquid crystal cell, And gray representation between white and white. As such, the polarizing film is one of the essential components of the TN Mode LCD.

As described above, in order to attach the polarizing film to the display panel, an automated polarizing film attaching device is used. According to the structure of the polarizing film attaching device according to the related art, a POL unit, which aligns and holds the polarizing film, A PANEL UNIT for moving the display panel to the POL unit and a ROLL UNIT having a roller for attaching the polarizing film to the surface of the display panel.

However, in the polarizer attaching apparatus according to the related art constructed as described above, there is a problem that the panel portion on which the heavy large display panel is mounted is moved in the horizontal direction, thereby occupying a considerable working space.

In addition, since a large-sized display panel of 30 inches or more is required to be aligned on the bottom of the equipment through the polarizer attaching device according to the related art, more than two people have to hold the end of the panel for seating, Structure. Particularly, in the case of a very large display panel, it is difficult for an operator to place a large display panel on a seating table.

Further, since the conventional polarizing film attaching device according to the related art operates according to the operation of the cylinder, it is difficult to precisely control the polarizing film attaching device.

In detail, when the initial mounting position of the claw portion 300 is set to less than 75 degrees on the panel portion 400, a sufficient space for placing the display panel 410 on the panel portion 400 is provided by an operator If the initial installation position of the pawl portion 300 exceeds 115 degrees on the panel portion 400, the volume of the frame body 200 may be increased or the pawl portion 300 may contact the frame body 200, and as a result, the installation space of the apparatus for attaching a film for a display panel is widened. This can not achieve the purpose of utilization of the work space to be achieved by the solution of the present invention.

The panel unit 400 includes a corner guide 421 for aligning the display panel 410 and a side guide 422. The corner guide 421 and the side guide 422 provide a means by which an operator can move the display panel 410 and fix it in the correct position when it is seated on the panel part 400. [

4, the claw portion 300 includes bar-shaped adsorption bars 321 and 322 (hereinafter, referred to as " bar ") having widthwise formed adsorption holes 322 and 332 at the upper and lower ends thereof for adsorbing and fixing the polarizing film 310, And a rear end vacuum plate 320. The front end vacuum plate 330 and the rear end vacuum plate 320 are provided with a plurality of front end vacuum plates 330 and a rear end vacuum plate 320, respectively.

The rear end vacuum plate 320 is provided with a guide rod 323 in the shape of a bar in the up and down direction on the pawl part 300.

Further, the attachment portion 500 has a function of moving up and down along the frame body 200 independently of the up and down movement of the panel portion 400. Accordingly, the panel unit 400 can be positioned at a predetermined distance from the panel unit 400 at an initial installation position of the panel unit 400. In this case, the description of the position of the attaching portion 500 will be described in the manner of operation of the apparatus for attaching a film for a display panel.

Hereinafter, a method of operating the apparatus for attaching a film for a display panel 100 according to the present invention will be described with reference to FIGS. 6 to 7. FIG.

The display panel 410 is mounted on the panel unit 400 by the initial operator. In this case, the operator can mount the display panel 410 at the correct position by the corner guide 421 and the side guide 422 provided on the panel unit 400. Thereafter, the display panel 410 is cleaned.

Also, since the pole portion 300 is initially installed at an angle of 75 to 115 degrees with respect to the panel portion 400, the operator is provided with a sufficient space for mounting the display panel 410 on the panel portion 400.

The display panel 410 is mounted on the panel unit 400 before the display panel 410 is mounted on the panel unit 400 by a worker in addition to the panel unit 400 on which the display panel 410 is mounted. The operator can easily mount the display panel 410 to the panel unit 400 by rotating the display panel 410 at a predetermined angle around the axis.

For example, referring to FIG. 5, a lower support 430 for supporting the display panel 410 may protrude at a predetermined distance from the panel 400 to separate the lower end of the display panel 410 at a predetermined interval Accordingly, the operator 1 can easily lift the display panel 410 up to the corner guide 421 of the panel unit 400. The display panel 410 can be accurately mounted on the panel unit 400 in accordance with the side guide 422 as a subsequent operation.

Also, when the operator places the display panel 410 on the panel unit 400, the lower supporter 430 returns to the home position, and the process of attaching the polarizing film 310 to the display panel 410 is continuously performed.

Thereafter, the process of attaching the polarizing film 310 to the pole portion 300 by the operator proceeds. Similarly, the operator can mount the polarizing film 310 at the correct position by the upper alignment guide 340 and the side alignment guide 350 provided in the pole portion 300. The polarizing film 310 may be attracted to the pole portion 300 by the distal end vacuum plate 330 provided at the pole portion 300 and the rear end vacuum plate 320 to maintain the position.

The polarizing film 310 may be adsorbed to the pole portion 300 by the adsorption bars 321 and 322 provided on the front end vacuum plate 330 and the rear end vacuum plate 320. Thereafter, the peeling process can be performed according to necessity of the polarizing film 310.

The pawls 300 on which the polarizing films 310 are mounted rotate about the first rotation axis 361 and are adjacent to the panel unit 400 in parallel while maintaining a predetermined gap therebetween.

Thereafter, the pole portion 300 rotates about the second rotation axis 362, and the upper end of the pole portion 300 is adjacent to the display panel 410. In this case, since the pawl portion 300 is rotated around the second rotation axis 362, the panel portion 400 is inclined at an angle that facilitates the operator to mount the display panel 410 on the panel portion 400 . Accordingly, the pole portion 300 may be further rotated about the second rotation axis 362, and the polarizing film 310 may be attached.

The upper end 311 of the polarizing film 310 is attached to the display panel 410 at an accurate position by the attachment roller 510 of the attachment part 500 positioned at the upper end of the panel part 400, Thereafter, the panel unit 400 moves upward. The rear end vacuum plate 320 moves while adsorbing the lower portion of the polarizing film 310 in accordance with the upward movement speed of the panel unit 400. In this case, the distal vacuum plate 330 can no longer adsorb the polarizing film 310, and the polarizing film 310 can be easily moved upward.

Accordingly, since the polarizer 310 is attached to the display panel 410 by vertically moving the panel 400 in the vertical direction, the display space or the polarizing film is moved in the horizontal direction, .

In addition, since the operator places the heavy large display panel 410 on the panel unit 400, the work efficiency can be increased. This has the effect of reducing the number of workers as compared with the case where two or more persons hold the end portion of the large size display panel to seat the large size display panel and then place it on the floor again.

The embodiment of the apparatus for attaching a film for a display panel of the present invention described above is merely an example and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. . Therefore, it is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims. It is also to be understood that the invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
