Abstract

The utility model relates to an LCD panel frame, in particular to a structure of an LCD panel, comprising a frame body. The LCD panel frame is characterized in that the frame body is formed with a small flanging by extending a small section from one end of an L-shaped side outwards on the basis of the L-shaped side, a plurality of L-shaped sides are stamped, and the two stamped L-shaped sides are combined into a whole body to form the panel frame by rotating. After being stamped, rotated and separated, the L-shaped sides are combined into a whole body by being welded at the junction points by laser, riveted, connected by screws, dissolved/in butt fusion or simultaneously using some of the ways. The LCD panel frame has the advantages that continuous mould discharging can be carried out on a piece of metal panel, and plat-plate material sheets can be stamped; and compared with the existing way, the LCD panel frame can save about 70% of raw material.

Description

Novel 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:

Novel LCD panel frame, comprise a framework, it is characterized in that: described framework is on the basis on a L shaped shape limit, and the end on L shaped shape limit stretched out one section forms a baby hem, punching out pluralizes successively, with the L shaped shape limit of the two punching out rotation formation panel frame that is combined into one.

Described L shaped shape limit is made by metal material.

Described 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.

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.

In order to prevent that the situation that framework 20 welding back pads get rusty from taking place, and can carry out antirust processing.

As shown in Figure 3, Figure 4, with pluralize a dull and stereotyped tablet 31 of whole piece metal material panel 30 punching out, progressive die discharging, tablet 31 L-shaped flangings vertically stretch out one section in the end of L shaped shape flanging minor face along minor face, and are inwardly closed.Flanging is rotated, is combined into a panel frame 40 profiles in perpendicular end surface then, then carry out at binding site that laser bonding, riveted, screw connect, certain several use simultaneously is integral in molten/welding or this several modes.

In order to prevent that the situation that framework 40 welding back pads get rusty from taking place, and can carry out antirust processing.

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.

Claims
