FIG. 1 is a plan view of a tray according to an exemplary embodiment v of the present invention.

Referring to FIG. 1, the tray 100 includes a plurality of rail accommodating portions 112. Alternatively, the tray 100 may include only one rail receiving portion. The guide rail 100 contains a rigid material that cannot be bent. The rigid material that can be used for the tray 100 may include plastic, metal, and the like. When the tray 100 is bent, the guide rail assembly 200 may be separated from the tray 100.

For example, a plurality of grip grooves 114 for holding the rail assembly 200 may be formed on both sides of each rail assembly portion 112. Grip grooves 114 formed on both sides of each rail assembly portion 112 are used to receive fingers or clips (not shown). A finger or a clip (not shown) may be received in the grip groove 114 to hold the rail assembly 200 so that the rail assembly 200 may be separated from the rail assembly receiving portion 112.

For example, a flexible printed circuit (FPC) receiving portion 116 may be formed under the guide rail assembly 112. The flexible printed circuit board 12 connected to the panel 10 and the circuit board 14 connected to the flexible printed circuit board 12 may be accommodated in the flexible printed circuit board receiving portion 116. The flexible printed circuit board receiving portion 116 receives the flexible printed circuit board 12 and the circuit board 14 so that the flexible printed circuit board 12 and the circuit board 14 cannot be separated from the panel 10.

The guide rail assembly 200 is received in the guide rail receiving portion 112 of the tray 100.

Fig. 2 is a perspective view showing the guide rail assembly of Fig. 1 and a panel accommodated in the guide receiving portion. Fig. 3 is a plan view showing the guide rail assembly of Fig. 1 and a panel accommodated in the guide receiving portion.

Referring to FIGS. 1 to 3, the guide rail assembly 200 receives the panel 10.

The rail assembly 200 includes a top rail 210, a bottom rail 220, and a sliding rail 230. The top rail 210, the bottom rail 220, and the sliding rail 230 may include a rigid material that cannot be bent. The rigid materials that can be used for the top rail 210, the bottom rail 220, and the sliding rail 230 may include plastic, metal, and the like. When the top rail 210, the bottom rail 220, and the sliding rail 230 may include a flexible material, the panel 10 accommodated in the rail assembly 200 may not be bent or damaged.

The top rail 210 is combined with the bottom rail 220. For example, the top rail 210 has substantially the same shape as the bottom rail 220. The top and bottom guide rails 210 and 220 have holes above them to receive the sliding guide rail 230. For example, the holes formed on the top and bottom guide rails 210 and 220 have slit shapes. In this embodiment, the top rail 210 and the bottom rail 220 can be combined with each other through a contact (not shown). Alternatively, the top rail and the bottom rail may be integrally formed.

The protective hole 250 may be formed on the inner corners of the top and bottom rails 210 and 220. For example, the protective hole 250 may be formed on each inner corner of the top rail and the bottom rail 210 and 220. The protective hole 250 is recessed outward from the corner of the panel 10. Therefore, the corners of the panel 10 may not be damaged by the frictional force between the panel 10 and the top or bottom rails 210 or 220.

For example, the flexible printed circuit board pull-out portion 260 is formed under the top and bottom guide rails 210 and 220. The flexible printed circuit board 12 attached to the lower part of the panel 10 and The circuit board 14 is accommodated in the flexible printed circuit board accommodating portion 116, and is pulled out toward the outer side of the guide rail assembly 200 via the flexible printed circuit board drawing portion 260. The flexible printed circuit board 12 and the circuit board 14 pulled out from the guide rail assembly 200 are housed in the flexible printed circuit board receiving portion 116 of the tray 100.

When viewed in a planar field of view, the inner surface of the bottom end guide 220 is larger than the outer contour of the panel 10. Therefore, when the sliding guide 230 is completely pulled out, the panel 10 reaches the ground from the bottom guide 220 by gravity.

The sliding guide rail 230 is accommodated in the top and bottom guide rails 210 and 220 through the holes through the top and bottom guide rails 210 and 220. The sides of the sliding guide rail 230 slide along the internal grooves formed on the top and bottom guide rails 210 and 220. Therefore, the sliding guide 230 slides in a vertical direction between the top and bottom guides.

For example, the protruding portion 232 may be formed on the upper surface of the sliding guide 230, and the guide groove 212 is formed on the upper portion of the top guide 210. When the sliding guide 230 slides in an inappropriate position, the protruding portion 232 may be blocked by the upper portion of the top guide 210. However, when the sliding guide 230 is slid in a proper position, the protruding portion 232 may pass through the guide groove 212. Therefore, the panel 10 may not be separated from the bottom rail 22 by the protruding portion 232 and the rail groove 212 during transportation.

For example, the upper part of the sliding guide 230 is protruded so that the upper part of the sliding guide 230 can be held by fingers.

In this exemplary embodiment, the buffer portion 240 is formed in the top rail 210. The buffer portion 240 prevents the panel 10 from being separated toward the top rail 210 and protects the panel 10 from impact during transportation. The buffer portion 240 may include an impact absorbing material. Can be used to ease Examples of the impact absorbing material of the punch portion 240 may include silicon, rubber, urethane, and the like.

The panel 10 is disposed on the upper surface of the sliding guide 230. For example, the lower surface of the panel is received on the upper surface of the sliding guide 230. The lower surface of the panel 10 is fixed by the inner surfaces of the top and bottom guide rails 210 and 220. The periphery of the lower portion of the panel 10 is fixed by the lower surface of the buffer portion 240 and / or the groove of the top rail 210.

4 to 5B, the lower surface of the top rail 210 is combined with the upper surface of the bottom rail 220. The sliding guide 230 is inserted between the top guide 210 and the bottom guide 220 to slide between the top and bottom guides 210 and 220.

6A and 6B are perspective views illustrating a method of accommodating a panel to a rack using the guide rail assembly of FIG. 1.

Referring to FIG. 6A, in order to receive the panel 10 on the rack 50, the guide rail assembly 200 on which the panel 10 is received is disposed on the rack 50.

The sliding guide rail 230 is pulled out from the side of the upper part of the guide rail assembly 200. During the pull-out of the slide rail 230, the sides of the upper portion of the panel 10 are blocked by the inner surfaces of the upper and lower rails 210 and 220 so that the panel 10 is not moved in the side direction of the panel 10 in. Therefore, the panel 10 slides along the upper surface of the slide rail 230.

The slide rail 230 continues to move so that the slide rail 230 is separated from the panel 10. The panel 10 reaches the ground from the bottom rail 220 by gravity. The height of the bottom rail 220 is low, so that the panel 10 does not damage the panel 10 when it reaches the ground from the bottom rail 220.

When the panel 10 reaches the ground from the bottom rail 220, the panel 10 is disposed on the upper surface of the frame 50. The top rail 210 and the bottom rail 220 are separated from the frame 50.

The panel 10 is held on a rack 50.

FIG. 7 is an exploded side view illustrating a guide rail assembly according to another exemplary embodiment of the present invention. The guide rail assembly shown in FIG. 7 is substantially the same as the guide rail assembly described in FIGS. 1 to 6B. Therefore, the guide rail assembly will be described with reference to FIG. 7 and any repetitive description will be omitted.

Referring to Fig. 7, the guide group 200 'accommodates the panel 10 (shown in Fig. 1).

The rail assembly 200 'includes a top rail 210, a bottom rail 220, and a sliding rail 230'.

Therefore, the sliding guide 230 ″ moves in the vertical direction of the top and bottom guide rails 210 and 220.

For example, the protruding portion 231 is formed on the lower portion of the sliding guide 230 '. The protruding portion 231 may not be formed to penetrate the upper portions of the top and bottom guide rails 210 and 220 Part of the hole. Therefore, although the sliding guide 230 'is sliding, the sliding guide 230' may not be separated from the top and bottom rails 210 and 220.

According to the present exemplary embodiment, the sliding guide 230 'may not be separated from the guide rail assembly 200' so that the guide rail assembly 200 'may be easily controlled.

8A to 8E are plan views illustrating a method for inspecting a panel using the guide rail assembly of FIG. 7.

Referring to FIGS. 1, 7, and 8A, the thumb and index finger of the examiner's hand 70 are accommodated in the grip groove 114. The thumb and forefinger hold the sides of the guide rail assembly 200 '.

The rail assembly 200 'is separated from the tray 100 by a thumb and an index finger. The rail assembly 200 'separated from the tray 100 is transported toward the rack.

Referring to FIG. 8B, the guide rail assembly 200 carried toward the rack 50 is installed on the rack 50. The flexible printed circuit board 12 connected to the panel 10 and the circuit board 14 connected to the flexible printed circuit board 12 are extracted from the rail assembly 200 '.

Referring to FIG. 8C, the upper part of the sliding guide 230 'is pulled out by the thumb and index finger, and the sliding guide 230' is extracted from the guide rail assembly 200. While the slide rail 230 'is being extracted from the rail assembly 200', the slide rail 230 'slides across the panel 10. When the sliding guide 230 'is separated from the panel 10, the panel 10 reaches the ground from the bottom guide 220 by gravity.

In the present exemplary embodiment, although the slide rail 230 'is completely pulled out from the top and bottom rails 210 and 220, the slide rail 230' may not be separated from the top and bottom rails 210 and 220. For example, a protruding portion (not shown) may be formed on the end portion of the sliding rail 230 'so that the protruding portion of the sliding rail 230' is blocked by the top and bottom rails 210 and Above 220. When the sliding rail 230 'is not separated from the top and bottom rails 210 and 220, the rail assembly 200' can be easily controlled.

FIG. 9 is a perspective view illustrating a guide rail assembly according to another exemplary embodiment of the present invention. The guide rail assembly shown in FIG. 9 is substantially the same as the guide rail assembly described in FIGS. 1 to 5. Therefore, the guide rail assembly will be described with reference to FIG. 9 and any repetitive description will be omitted.

Referring to FIGS. 1 to 9, the guide rail assembly 201 receives the panel 10.

The rail assembly 201 includes a side rail 215 and a sliding rail 230. The side guide rails 215 and the sliding guide rail 230 may include a rigid material that cannot be bent. Rigid materials that can be used for the side rails 215 and the sliding rails 230 include plastic, metal, and the like. When the side guide rail 215 and the sliding guide rail 230 may include a flexible material, the panel 10 accommodated in the guide rail assembly 201 may be bent or damaged.

The side guide rails 215 are integrally formed. The upper end of the side guide rail 215 has a hole to receive the sliding guide 230. For example, the side guide rail 215 contains plastic and is integrally formed through an injection mold.

The guard hole 250 may be formed on an inner corner of the side guide rail 215. For example, the guard hole 250 may be formed at each corner of the side guide rail 215. Therefore, the corners of the panel 10 may not be damaged due to the friction between the flat plate 10 and the side guide rails 215.

For example, the flexible printed circuit board extraction portion 260 is formed under the side guide rail 215. The flexible printed circuit board 12 and the circuit board 14 attached to the lower portion of the panel 10 are housed in the flexible printed circuit board receiving portion 116 and are directed toward the guide rail assembly through the flexible printed circuit board extraction portion 260 The outside of 201 is extracted. The flexible printed circuit board 12 and the circuit board 14 extracted from the guide rail assembly 201 are housed in the flexible printed circuit board receiving portion 116 of the tray 100.

The sliding guide 230 slides along a hole penetrating a part above the side end guide 215 to be accommodated inside the side end guide 215. The side surface of the sliding guide rail 230 slides along a groove formed inside the side end guide rail 215. Therefore, the sliding guide 230 moves in the vertical direction of the side guide 215.

For example, the protruding portion 232 may be formed on the upper surface of the sliding guide 230, and the guide groove 212 may be formed on the upper portion of the side guide 215. When the sliding guide 230 is slid in an inappropriate position, the protruding portion 232 may be blocked by the upper portion of the side guide 215. However, when the sliding guide 230 is slid at a proper position, the protruding portion 232 may pass through the guide groove 212. Therefore, the panel 10 can pass through the protruding portion 232 and the rail groove 212 without being separated from the side end rail 215 during transportation.

In this embodiment, the buffer portion 240 is formed in the side guide rail 215. The buffer portion 240 prevents the panel 10 from being separated toward the side end rail 215 and protects the panel 10 from impact during transportation.

The panel 10 is disposed on the upper surface of the sliding guide 230. For example, the lower surface of the panel 10 is received on the upper surface of the sliding guide 230. The side surface of the panel 10 is fixed by the inner surface of the side end rail 215. The periphery of the upper portion of the panel 10 is fixed by the lower surface of the buffer portion 240 and / or the groove of the side guide rail 215.

According to this exemplary embodiment, the top and bottom rails are replaced by the side rails 215 that are integrally formed. Therefore, the number of components of the guide rail assembly 201 is reduced so that production can be simplified.

In order to test the effectiveness of the guide rail assembly and the tray provided with the guide rail of the present invention, the panel was tested through the following experiments. The formation of cracks in the panel was examined through a microscope.
