Abstract

The utility model relates to an LCD (Liquid Crystal Display) panel frame, comprising a frame body. The LCD panel frame is formed by the butt joint of two pieces of L-shaped workpieces or four pieces of elongated workpieces. An excurved folding part is formed by the edge fold of the outline of the frame body. The frame body can be formed by the butt joint of a plurality of workpieces, so the technique is more flexible than the known technique on the coining of the workpieces of metallic material. The utility model makes use of the arrangements of different workpieces to do coining, which can use maximal material area. All material is effectively used, which avoids wasting and can decrease the cost of waste treatment.

Description

The LCD panel frame

Technical field

The utility model relates to a kind of LCD panel construction, particularly a kind of LCD panel frame that can be used as the LCD panel frame of Thin Film Transistor-LCD (TFT-LCD) panel front baffle and backlight module frame.

Background technology

Generally speaking, the TFT-LCD panel mainly can be divided into three partly, be respectively LCD panel, TFT panel and backlight module, and utilize a metal framework and combining of a plastic frame that the function of each assembly of fixed panel or module is provided jointly, this plastic frame provides can settle each assembly or module base thereon, metal framework is then fixed each assembly or module in order to compacting, and lives plastic frame with time-frame.

Known metal framework is that the full wafer metallic sheet material thrusts the type of processing with central part, and the size of this central part system is consistent with panel size; Shown in Figure 1A, known framework cuts into the sheet metal 12 of suitable size earlier with a metal coiled strip 10; And shown in Figure 1B, on sheet metal 12, carry out the processing of punching/side cut, with excision sheet metal 12 edges unnecessary waste material, and outward flange carried out flanging to form outside 14; And shown in Fig. 1 C, sheet metal 12 is carried out punching forms window aperture 16, and make panel since then window aperture 16 expose, shown in Fig. 1 D.

Because known metal framework is through the processing of punching/side cut, and the removal of middle body material is formed this window aperture, the metal material of these removals is considered as a waste material, need to handle in addition, and along with the size of display pannel is more and more big, it is big that the material unaccounted-for (MUF) of central part also becomes relatively, and the material area that window aperture need be removed accounts for the actual use amount of full wafer sheet metal more than 2/3, and is very big for influence on the material cost.

Summary of the invention

Fundamental purpose of the present utility model provides a kind of LCD panel frame, can use all metal materials, and then reaches effective saving cost, avoids the effect of waste of material.

The usable floor area that promotes material of the present utility model reduces the weight of transporting of material, thereby can save freight charges and alleviate handling workload.

The utility model can reduce produces the waste material that retain the back.

Above-mentioned purpose of the present utility model is achieved in that a kind of LCD panel frame, it is characterized in that comprising a framework, and it is made up of two L type workpiece or the butt joint of four elongated workpiece, and is provided with kink outside around the outer rim of this framework.

The utility model is elaborated with instantiation below in conjunction with accompanying drawing.

Description of reference numerals: 10 metal coiled strips; 12 sheet metals; 14 outsides; 16 window aperture; 20 metal materials; 22L type workpiece; 24 frameworks; 26 waste materials; 28 outer kinks; The 30LCD panel frame; 32 elongated workpiece.

Embodiment

The utility model is with unitary piece of material central part to be thrust the shortcoming that machine-shaping causes material unaccounted-for (MUF) for improving known LCD panel frame system, and a kind of new LCD panel frame structure is proposed, it is the structure that metal material is struck out a plurality of L type workpiece or elongated workpiece, reprocess after making it a plurality of workpiece can be combined into a framework, and then can effectively utilize each position of metal material, reach the saving material cost.

Fig. 2 D is a perspective view of the present utility model, as shown in the figure, one LCD panel frame 30 utilizes modes such as riveted, welding or welding that two L type workpiece 22 are docking together and forms a framework 24, and the outer rim of this framework 24 is carried out flanging, to form an outer kink 28.Also can be coated with one deck rust preventive or rust protection paint, use the situation of getting rusty that easily produces when docking of preventing because of the welding mode in the joint system of two L type workpiece 22 of framework 24.

For explanation the utlity model has the effectively characteristics of materials used, will cooperate a following manufacturing process embodiment to be described in detail.At first, shown in 2A figure, with metal material 20 punching out of a whole piece L type workpiece 22 that pluralizes; Obtain again after a plurality of L type workpiece 22, with per two L type workpiece 22 is one group, engaging one another is integral, to form the structure of a framework 24, shown in Fig. 2 B, wherein, the workpiece juncture is modes such as riveted, welding or welding, and behind the workpiece joint, middle formed hollow space is a window aperture, its undersized is in panel size, and make panel since then window aperture expose.

In addition, for the joint of avoiding framework 24 easily causes the generation of getting rusty, more can carry out an antirust treatment step, it is joint coating one deck rust preventive or rust protection paint at this two L type workpiece 22, gets rusty preventing.

Continue, shown in Fig. 2 C, cut this framework 24 of integer, remove unnecessary waste material 26 parts around this framework 24, adjust the correct size of framework 24, and again the outward flange of this framework 24 is carried out flanging with precision, shown in Fig. 2 D, forming outer kink 28, and then finish a LCD panel frame 30.

In the foregoing embodiments, these framework 24 structures are formed by 22 butt joints of two L type workpiece, and two butt ends of this two L type workpiece 22 are that vertical plane engages, in addition, the utility model also has other and implements aspect, and as shown in Figure 3, this framework 24 is made up of two L type workpiece 22, but two butt ends of this two L type workpiece are the inclined-plane to be engaged, slightly different with the L type workpiece shown in Fig. 2 B; In addition, one metal material punching out can be pluralized an elongated workpiece 32 of the utility model, and utilize four elongated workpiece 32 mutually butt joint form a framework 24 structures, as shown in Figure 4, wherein, docking mode also can be that vertical plane engages or the inclined-plane engages.

The structure of the utility model improvement LCD panel frame can effectively be apt to use all metal materials, and the saving material cost avoids waste, and reaches the effect of making the best use of everything, so can reduce cost and meet economic benefit.And because of it has saved the usable floor area of metal material, thus the weight of materials used carrying also can significantly reduce, so can save freight charges and transportation.In addition, it is limited that the utility model cuts the waste material of removal, also can reduce and produce the waste material that retain the back, reduces the waste disposal cost, also has the environmental protection effect.

Above-described embodiment only is explanation technological thought of the present utility model and characteristics; its purpose makes those skilled in the art can understand content of the present utility model and is implementing according to this; and can not with qualification scope of the present utility model; all equalizations of doing according to the spirit that the utility model disclosed change or modify, and must be encompassed in the protection domain of the present utility model.
