Description

200400786

1. [Technical field to which the invention belongs] A boat month Λ has: a processing technology of LCD panels, especially the processing process of a type of LCD panel frame, used to process the front of the thin film transistor display (TFT-LCD) panel Frame and backlight module frame. 2. [Previous Technology] Generally speaking, TFT-LCD panel can be mainly divided into three parts, including L ^ D panel, TFT panel and backlight module, which are provided by the combination of a metal frame and a plastic frame. The function of each component or module of the fixed panel. This frame provides a base on which each component or module can be placed. The J frame is used to press and fix each component or module, and at the same time frame the plastic frame. When frame, it is based on the whole piece of metal part: punching out: the workman's, and the size of the central part is cut with 钔 〇 'to cut into a metal plate of appropriate size 12, = metal plate) 12 Processing is also possible; then, as shown in the figure, the excess waste on the edge of the metal plate 12 is cut off, and then the metal plate 12 is folded out of the 14 steps, as shown in the picture; As shown in Figure 1D,

Li: This window can be completed when it is exposed-as shown in the picture. In addition, the above process steps will be adjusted according to the mold design or workpiece. Due to the above processing method, the material in the center of the metal plate is removed

$ 4Page 200400786 V. Description of the invention (2) To form the window hole, the removed metal waste is regarded as one that must be treated separately; "As the display panel of the display grows, the material in the central part is lost. Relatively large, and ^

The area of the material to be removed from the hole occupies the actual thickness of the entire metal plate, which has a significant impact on the cost. X In view of this, the present invention is to propose a method that can be effective. 3. [Invent the process of the present invention, which avoids the wave of materials. The process of the present invention, because it can also significantly increase the process of the present invention, its system. In order to achieve the material steps, the workpieces are then docked with each other in the steps. The main purpose is to provide an LCD panel frame that makes good use of all metal materials, so it can effectively save material costs, reduce costs and meet Economic benefits. = Another purpose is to provide a processing method for the LCD panel frame, which saves the use area of the material, so the weight of the material used for transportation is reduced, which can save freight and transportation. Another object is to provide an LCD panel frame that can reduce the waste materials remaining after production, in order to reduce the number of waste materials treated. The above purpose, the processing process of the present invention is first performed by punching a metal material into a plurality of pieces. The L · shaped workpiece or the elongated shape is subjected to the joining step, and the two L-shaped workpieces or the quadrilateral shaped pieces are formed together to form a frame body; finally, a cutting and shaping is performed to remove the excess part around the frame body to precisely Adjust the frame

Then complete one or five, description of the invention (3) the correct size, and hemming the outer edge of the LCD panel frame. Among them, after the above-mentioned workpiece joining step, a processing step can be performed to avoid the occurrence of rust at the joint. Under the scales, Gu Yi understands the purpose, technical content, and special features of the present invention through specific implementation examples and accompanying drawings. Pay Points and the Achievements Achieved

The present invention is to improve the conventional LCD panel frame by using the central part of the entire piece of material to punch and form the material, which results in the loss of material. The new LCD panel frame is manufactured by stamping metal materials into two parts when blanking. One piece of L-shaped workpiece or four pieces of long workpiece material, and the workpiece material is assembled into a frame and then processed to effectively use each position of the metal material to achieve the effect of saving material costs.

Figures 2A to 2D are schematic diagrams of the f-step structure of the LCD panel processing process of the present invention. As shown in the figure, first, the blanking step is performed as shown in Figure 28, which is a whole piece of metal The material 20 is punched to form a plurality of L-shaped workpieces 22; after obtaining a plurality of [shaped workpieces 22, every two [shaped workpieces 22 are 々 groups' for joining steps, using riveting, welding or smelting, etc. The two L-shaped workpieces 22 are butt-jointed into a whole, as shown in FIG. 2B, to form a frame 24 '. The size of the window hole formed in the middle portion is slightly smaller than the size of the panel, and the panel can be exposed from this window hole. . After 70% of the above joining steps, in order to avoid that the joint of the frame 24 is easy to guide

Page 6 V. Description of the invention (4) If rust is caused, a rust-proof treatment step can be performed. A layer of rust-proof agent or anti-rust coating is applied to the joint of the workpiece 22, and it is easy to produce when the joint is docked. Recording status. Finally, if ^ ^ is carried out: cutting and shaping step, it is to remove the waste material 26 shown in the frame 24 first to precisely adjust the correct size of the frame 24, and the outer edge of the frame 24 is performed overnight. Fold the edges, as in the 2nd, 2nd, 2nd folding ... to complete an LCD panel frame 30.卩 The outer curve is formed. Among them, the aforementioned frame 24 structure is composed of two L-shaped workpieces and the two butt ends of the two L-shaped workpieces 22 are vertical planes; cattle 22 pairs; and the structure of the frame 24 also has other implementations. State 1; In addition to this, the joint is beveled, and the [type workpiece is slightly better than one pair as shown in Figure 2B: 'The present invention can punch a metal material into a plurality of long workpieces and use 5 Four pieces of long-shaped work piece 3 4 Japanese stone batch 3 2 '4 shown in the figure. The cow 2 is butted to form each other-the structure of the frame 24, as the first. Since the processing process of the present invention effectively covers the full use of the material, it can save:] There are metal materials, which can reduce costs and achieve economic benefits. And because of its savings in freight and handling. In addition, 4; :: = reduce, so it can save and reduce the waste remaining after production, except for the limited waste, p, Xinxin Village to reduce the amount of waste disposal. Point, the technical ideas and special features of its purpose are implemented on the basis of this, and you cannot use "; ::::::;: Ming": 200400786 V.
