Abstract

The utility model provides an LCD panel framework, and relates to LCD panel structures. The framework body is formed by four butt joint L-shaped flangings; a metal panel is punched into complex edges in sequence, and each four punched L-shaped edges rotate, and are combined in a cross manner along the central position of the panel framework body; and after punching, the L-shaped flangings are rotated and separated, and form a whole at a combination point through laser welding, riveting, screw connection and solution/fusion joining, or through certain manners therein used simultaneously. The LCD panel framework has the benefits that the metal panel conducts continuous die discharging and is punched into flat tablets, so that compared with the prior art, 70% raw materials are saved.

Description

The LCD panel frame

Technical field

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

Background technology

Generally speaking, the TFT-LCD panel mainly can be divided into three parts, 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 and the base on it, metal framework is then fixed each assembly or module in order to compacting, and lives plastic frame with time-frame.

Because metal framework is through the processing of punching/side cut in the original production process, and the removal of middle body material is formed the hollow window oral pore, and (metal material of these removals is considered as 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 waste of the material of middle body also becomes relatively, and the material area that need remove of window aperture accounts for more than 2/3 of actual use amount of full wafer sheet metal, very big for influence on the material cost.

China Patent No. 200320103221.9, patent discloses a kind of panel frame mode for " LCD panel frame ", comprises a framework, is formed by two L type workpiece or four microscler workpiece butt joints, and the outer rim flanging in this framework forms kink outside again.Shown in Figure 1A, with metal material 20 punching out of a whole piece L type workpiece 22 that pluralizes, after obtaining a plurality of L type workpiece 22, with per two L type workpiece 22 is one group, and interosculating is integral, to form the structure of a framework 24, shown in Figure 1B, wherein workpiece is in conjunction with adopting modes such as riveted, welding or welding, and after the workpiece combination, middle formed hollow space is window aperture.

Frame mode on this is commonplace in actual use, some producers have adopted another kind of panel frame mode in order to change this mode, shown in Fig. 2 A, metal material panel 20 punching out of whole piece are become peripheral C type limit 22 and in C type limit 22 again on a L type of punching out limit 23, the order punching out becomes some a plurality of successively, then each a C type limit 22 and a L type limit 23 are formed one group, interosculate and be integral, to form the structure of a framework 24, shown in Fig. 2 B, with the workpiece junction by laser bonding, riveted or the mode combination that welds.

In above-mentioned panel frame, be not difficult to find out for after the combination of type limit, the control of pad is all within two, this is in order to save process, but present laser welding technology is very ripe, control for the quantity of pad has seemed so unimportant, so how saves metal material more and just seems particularly important.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of existing panel frame production method that is different from, and saves the LCD panel frame of metal material more.

The technical matters that the utility model solved realizes by the following technical solutions:

A kind of LCD panel frame, comprise a framework, it is characterized in that: described framework is made up of four L type flanging butt joints, and punching out pluralizes successively on the metal material panel, with the L type limit rotation combination of per two punching out, along the center right-angled intersection combination of panel framework.

Described L type flanging is made by metal material.

Described L type flanging through after rotating, separating, passes through certain several joint that use simultaneously in laser bonding, riveted, screw connection, molten/welding or this several modes at the abutment after punching press is finished.

When the further technical scheme of the utility model also is included in the L type flanging combination of per two punching out, can add the long strip type limit at adjacent L type flanging perpendicular end surface binding site place, can make the panel frame of different size according to the difference of panel frame size.

The beneficial effects of the utility model are to carry out progressive die discharging on a metal material panel, and punching out becomes dull and stereotyped tablet, can save about 70% starting material with respect to existing mode.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 3, Figure 4, with the whole piece metal material panel 50 punching out dull and stereotyped tablet 51 of a L type that pluralizes, progressive die discharging.L type flanging is rotated, and along the central point right-angled intersection of panel frame 60 butt joint, adjacent L moulding mixture sheet 51 vertical plane combinations carry out at binding site that laser bonding, riveted, screw connect, certain several use simultaneously is integral in molten/welding or this several modes.

As shown in Figure 5, when the vertical plane of adjacent L moulding mixture sheet 51 docks along the central point right-angled intersection of panel frame 60, between docking point, add long strip type limit 52, then the abutted surface of long strip type limit 52 and L moulding mixture sheet 51 is carried out that laser bonding, riveted, screw are connected, certain several use simultaneously is integral in molten/welding or this several modes according to the different length and width specifications of panel frame 60.

More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
