BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for transporting a backlight assembly. More specifically, the present invention relates to a tray for increasing transport efficiency and removing foreign material causing elements by changing tray materials and shapes.

In general, liquid crystal display (LCD) monitors and notebook monitors are widely used as fundamental solutions to the disadvantages of general CRT monitors such as size and electromagnetic wave generation, and are expected to replace CRT monitors in the near future. In particular, LCD monitors and notebook monitors in the configuration includes a backlight assembly for providing a backlight, and is manufactured by a company that specializes in handling the above. In addition, LCD monitors and notebook monitors are produced by assembling the backlight assembly supplied by a specific company in the factory.

The backlight assembly is produced by a specialized company and then transported to an LCD monitor or laptop monitor assembly plant, where the backlight assembly is stored in a plastic bag in multiple layers together with a cushioning material. In the LCD monitor assembly factory, the plastic bag and the cushioning material are taken out of the box, the plastic bag is opened, and the backlight assembly is pulled out. The drawn assembly is then used to assemble the LCD monitor.

However, in this case, since the backlight assembly is made so precisely, great care must be taken to pack or open the plastic bag, and the backlight assembly is often damaged during the packaging or opening of the backlight assembly. In addition, there were frequent damages caused by contact or dropping with other backlight assemblies during transportation.

In particular, the plastic bag for packaging the backlight assembly is expensive because of the antistatic treatment. As a result, the packaging cost for packaging the backlight assembly is high, which in turn causes a price increase in manufacturing LCD monitors or notebook monitors. In addition, the opened plastic bag or the buffer material is discarded as a waste. The plastic bag is not decomposed naturally, and even when incinerated, harmful substances such as dioxins may be generated, causing environmental pollution.

From now on, a tray carrying a conventional backlight assembly will be described in detail with reference to the drawings in order to examine the comparative advantages between the prior art and the present invention in earnest. 1 shows a conventional tray for carrying a backlight assembly. First, the configuration of the present invention can be divided into a housing 10, an outer frame 20, a protrusion 12, a rib 14, and a concave portion 30, as shown in the drawing.

Here, the accommodating portion has a rectangular shape in which accommodating grooves 10a are formed to accommodate the backlight device 1 in a horizontal state.

In addition, the outer frame part 20 is configured to include an upward bent surface 22 and a downwardly bent surface 23, wherein the upwardly bent surface 22 is integrally formed with the bottom surface of the receiving groove 10a. Formed in the front, left, and right, respectively, protruded upwardly, while the downwardly curved surface 22 extends to the upwardly curved surface 22 and extends horizontally to the outside, but its end portion is downwardly It is bent to form an inclined outward toward the lower end.

The protrusion protrudes downward from the edge of the receiving groove 10a to make surface contact with the upper surface of the support frame 4 that supports the outside of the backlight device surface 2 positioned below the receiving groove 10a. Doing.

On the other hand, the rib 14 is formed on the bottom surface of the receiving groove (10a) is formed to protrude to the bottom of the bottom surface to prevent the twist and the lower sag generated on the bottom surface of the receiving groove (10a).

Lastly, the concave inlet 30 is formed on the front and rear or right and left surfaces extending from the bottom surface of the storage groove 10a, but the outer frame portion 20 is easy to draw out of the backlight device accommodated in the storage groove 10a. Is formed on the inner side of the upwardly bent surface 22.

In general, the transport tray of the conventional backlight assembly has been used by the production molding of soft polyethylene (polyethylene) material. As a result, the load of the backlight itself during multi-stage loading tends to cause deformation of the lower tray and product damage. In particular, it has been difficult to apply to the new large backlight assembly based on the 42-inch in recent years.

In addition, the logistics transport efficiency was significantly lowered due to the need for a separate transport trolley for bulk transportation. In addition, the floor contact area between the product and the tray was widened, causing foreign materials to be transported.

Accordingly, an object of the present invention is to increase transport efficiency and minimize foreign matter causing factors by making and using a separate tray to improve the above problems.

The configuration of the transport tray of the backlight assembly according to the present invention for achieving the above object is characterized in that it comprises a four extrusion bar, and an injection molding for coupling the extrusion bars to each other.

The tray according to the invention is particularly easy to carry a backlight assembly, such as a 42 inch large TV, as already mentioned earlier. The transport tray of a backlight assembly of a conventional LCD and laptop monitor uses injection or injection molding, that is, a method of heating a plastic molding material in a cylinder to soften it, and then quickly pushing it into a cold mold to form it. In this case, it was possible to float the pattern at once, but it was not particularly problematic in that the size was limited. Due to this condensation, the transport tray of the backlight assembly according to the invention is of further value.

Then, the configuration and material will be described in detail with reference to the drawings. First, FIG. 2A is a plan view illustrating a tray as a first embodiment according to the present invention. As can also be seen in FIG. 2A, the four extrusion bars 104 herein are made by an extrusion molding method of supplying fuel to the extruder and pushing it out of the mold to convert it into a continuum with a constant cross section. It is made of rigid polyvinyl chloride and has a rectangular shape. Particularly, a hole or a hole is formed uniformly or randomly in a flat part where the handle 104 and the backlight assembly are accommodated and supported. It is. This is because, above all, it relates to manufacturing costs.

It should be noted here in particular with respect to the extrusion bar 104 that the extrusion bars 104 are not limited in their length. In other words, it is possible to mass produce extruded bars of any type from short to long.

And according to any one of the above-mentioned order while describing the extrusion bar 104 so far, as shown in Fig. 3 as an example, from the time of molding in the mold machine, It creates a certain pattern that seems to put two 'n' characters together. In the drawings, in particular, the length A of the handle 104 must be secured at least approximately 18 mm for material transport. And the height (B) is approximately 63mm, and in order to accommodate the backlight assembly, the 'C' shape of the lower part (C) is about 64mm, the overall thickness (D) is about 3mm It is preferable to secure and form. This is, of course, based on the large 42-inch screen.

In addition, the above-mentioned four extruded bars 104 may be packed with injection moldings (or injection moldings) made of a separate polycarbonate sheet, or may be combined with other products on the injection moldings. In order to reduce friction loss, packing is performed by coating a kind of impact resistant thermoplastic resin such as ABS (Acrylonitrile, Butadiene, Styrene).

More specifically, first of all, the injection molded polycarbonate is a thermoplastic material first developed by H. Schnell of Bayer, Germany in 1958 and first commercially produced in 1958. In particular, the impact of 150 times stronger than tempered glass and 250 times higher than that of flat glass completely compensates for the impact of glass and its permeability. It can protect people and property from various safety and theft accidents. Is recognized as the perfect alternative to glass.

In addition, ABS is a comprehensive engineering that provides only the advantages of stiffness, chemical resistance, and excellent mechanical properties of acrylonitrile, impact resistance of butadiene, and gloss and formability of styrene. With this added plastic, if it is given different requirements according to its use, it must meet the required properties by appropriately adjusting the composition ratio of ABS resin, adjusting the molecular weight of resin and changing additives.

Of course, the production of this product is technically possible, and there are differences in manufacturing methods depending on the company, but most ABS manufacturers produce a plurality of qualities according to the use. Particularly in the resin, the composition of A to B to C can be produced by changing theoretically infinitely, but in general, A is 20 to 30%, B to 5 to 40%, and C to about 70%. It is intended to have practically necessary properties. Therefore, ABS resin is a simple copolymer of these three components.

On the other hand, briefly looking at the above-described protrusions 106, the protrusions 106 are injection molded to the four packing parts in order to prevent the flow of the upper tray and the lower tray when the backlight assembly is multi-stage loading The upper portion of the protrusion 106 is a 'b' shape that corresponds to the 'b' shape of the rectangular corner, and is produced from the mold machine from the beginning at the time of casting. Of course, with respect to this shape will not be limited to the two protrusions 106 as shown in Figure 2a with the edge portion removed from the 'b' shape can be made. As a result, the shape of the corner seating portion (not shown) is made to be an optimized design, so that the mutual use of products can be made common.

Subsequently, referring to the rear view of FIG. 2D based on the right side view of FIG. 2A, the front view of FIG. 2C, and the cut plane of AA ′ of FIG. 2A, the injection bar 100 may also be seen as shown in the drawings. The injection part 102 of the packing part surrounding the edge of the field is shown as an example of wrapping only a part of the bars. However, the present invention is not limited thereto, and the case of wrapping the entire corner of the injection bars may be considered.

In addition, as shown in FIG. 4 as a second embodiment according to the present invention, the range is extended to another forming pattern, that is, the extrusion bar 204 without holes. Briefly, the configuration is composed of the four extruded bars 204 having a rectangular shape and the injection moldings 202 of the packing part to which the extruded bars 204 are coupled, and in particular, the injection molded parts 202. The projection 206 is attached to prevent the flow of the upper transport tray and the lower transport tray when the backlight assembly is stacked in multiple stages.

Therefore, based on the formation process and the process so far, as shown in Figure 2a as a result, the transport tray of the backlight assembly according to the present invention is the bottom surface is open, so that when the product is seated between the trays Foreign matter generation factor is not caused.

In addition, by using the injection molding using a rigid material in the four corner packing portion it is possible to improve the efficiency of logistics, such as a separate transport cart is unnecessary when multi-stacking the transport tray of the new large backlight assembly.
