Abstract

The utility model relates to a TFT-LCD (Thin Film Transistor Liquid Crystal Display) metal frame. The TFT-LCD metal frame is characterized in that the metal frame comprises two L-shaped metal pieces and two strip-shaped metal pieces; and the two L-shaped metal pieces and the two strip-shaped metal pieces are laser welded and fixed in an end-to-end way to form a square flat frame, and the length of the short edge of the L-shaped metal piece is equal to the width. The TFT-LCD metal frame has the advantages that when the L-shaped metal pieces and the strip-shaped metal pieces are fabricated, because the length of the L-shaped metal piece is equal to the width, the two L-shaped metal pieces can be formed by cutting a wide square metal sheet, and when the metal pieces are cut from an entire metal sheet, only cutting mechanical equipment or common stamping equipment is adopted to conduct simple material cutting operations, thereby avoiding the investment of more resources and achieving the effect of saving more resources.

Description

A kind of TFT-LCD metal framework

Technical field

The utility model relates to a kind of TFT-LCD metal framework, particularly a kind of TFT-LCD metal framework of making material-saving.

Background technology

The TFT-LCD full name is radiationless thin film transistor active matrix LCD, and each assembly of TFT-LCD product constantly improves innovation when manufacturing, progressively send out to more energy-conservation more environmental protection.

Traditional TFT-LCD framework is by stamping out openning shape metal frame on the block of metal plate, the rectangle sheet metal that hollows out in the middle of the openning shape metal frame can't more effectively be utilized, and cause a large amount of waste materials, so manufacturing cost is higher.Along with the size of liquid crystal panel is increasing, tablet is saved more and more important in the middle of it.Emerge the marker method and the logical riveted joint of a lot of material-savings or be welded into required product, but size is big more, as processing by existing marker method, the more problem of can deriving: manufacturing cost drops into more, need to drop into large-scale bin, bump-cutter machine, feeder, the large-tonnage punch press, also need to cooperate the large stamping die of different size, entire making process is quite cumbersome, needs to drop into large-scale haulage equipment or the like, though the large size panel material obtains certain saving, corresponding wright need drop into a certain proportion of equipment.

The utility model content

The technical problems to be solved in the utility model provides a kind of TFT-LCD metal framework of making material-saving.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of TFT-LCD metal framework, its innovative point is that it comprises: two L shaped metalworks and two strip metalworks, the end mutual radium-shine welding of head and the tail of described two L shaped metalworks and two strip metalworks is fixing to constitute a hollow plane framework, and the bond length of described L shaped metalwork is identical with width.

Advantage of the present utility model is: when making L shaped metalwork and strip metalwork, because the bond length of L shaped metalwork is identical with width, two L shaped metalworks can be by the rectangle sheet metal excision forming of a broad, therefore when the full wafer sheet metal carries out the cutting of metalwork,, only need to drop into to cut out plant equipment or medium-sized pressing equipment, carry out simple material cutting, avoid the input of more resources, reached the more effect in supernumerary segment source.

Description of drawings

Fig. 1 is for adopting the arrangement synoptic diagram of two L type metalworks of tradition on sheet metal;

Fig. 2 is the utility model TFT-LCD metal framework structure synoptic diagram;

Fig. 3 is the arrangement synoptic diagram of the L shaped metalwork of the utility model on sheet metal.

Embodiment

As shown in Figure 2, the utility model provides TFT-LCD metal framework, it comprises 1,2 and two strip metalworks 3,4 of two L shaped metalworks, L shaped metalwork 1, strip metalwork 3, L shaped metalwork 2, strip the metalwork 4 mutual radium-shine welding of head and the tail are successively fixed, and constitute a hollow plane framework.

The bond length of above-mentioned L shaped metalwork 1,2 is identical with width, both can be spliced into a rectangle sheet metal, making L shaped metalwork at 1,2 o'clock, it is by the sheet metal punching press or the cutting forming of full wafer, its arrangement position on sheet metal as shown in Figure 3, each L shaped rectangle that is arranged in opposite directions in twos, each rectangle is carried out arranged distribution according to the developed width of full wafer sheet metal, makes full use of sheet metal.

Claims

1. TFT-LCD metal framework, it is characterized in that it comprises: two L shaped metalworks and two strip metalworks, the end mutual radium-shine welding of head and the tail of described two L shaped metalworks and two strip metalworks is fixing to constitute a hollow plane framework, and the bond length of described L shaped metalwork is identical with width.
