Description

frame components

technical field

The utility model relates to a frame component, in particular to a frame component for forming a plane display frame, which is suitable for welding methods other than laser welding.

Background technique

The flat panel display has the advantages of thin and light appearance, low power consumption and relatively low radiation pollution, so it is widely used in various electronic products. Taking a liquid crystal display as an example, the liquid crystal display module mainly includes main components such as a liquid crystal display panel and a backlight module, and a complete liquid crystal display module can be formed by fixing the above components with a plurality of frames.

Please refer to FIG. 1a to FIG. 1c to illustrate the manufacturing steps of the existing frame. First, the metal coil or sheet is cut into metal plates 11 of appropriate size. Next, the desired window hole 12 is formed in the central area of the metal plate 11 by cutting or punching. Finally, subsequent processing steps such as edge folding are performed to form the frame 13 as shown in FIG. 1c. In the above-mentioned process, the metal material with equal area generated when forming the window hole 12 is not highly utilizable, and is even regarded as waste material, so the material cost of the frame 13 cannot be effectively reduced.

In view of the above-mentioned problems, currently there is a preparation method of combining a plurality of components into a combined frame. As shown in FIG. 2a, the frame 2 is formed by joining two L-shaped frame components 21 relative to each other. As shown in FIG. 2 b , in this way, the L-shaped frame component 21 can be efficiently cut out from the metal material 22 to reduce waste generation.

Referring to Figures 3a to 3d, in addition to the L-shaped frame components, there are also a variety of frame components with different shapes, such as equilateral U-shaped frame components 31, unequal U-shaped frame components 32, The elongated frame components 33,34. In addition, two frame components with different shapes can also be joined to form a frame, for example, two L-shaped frame components 35 and one strip-shaped frame component 36 are joined to form a frame as shown in FIG. 3 d .

No matter what type of frame components are used to form the frame, a joining process is inevitably required to join the frame components. At present, laser welding or riveting is used to achieve the purpose of joining. However, the cost of laser welding equipment is high, and more professional technicians are required to operate, which is also a big burden on manufacturing costs. However, the method of riveting with a punching machine is not as strong as the method of laser welding, the processing steps are more complicated, the productivity is not good, and the accuracy of riveting is difficult to control, which makes the failure rate of the frame joined by riveting higher.

To sum up, how to join the combined frame at a relatively low cost, and its joint strength and reliability are similar to the laser welding method is the goal that needs to be worked hard at present.

Detailed ways

The frame component of the present utility model is a metal material, and its appearance can be L-shaped, equilateral U-shaped, unequal-edge U-shaped or strip-shaped, etc., and is used to form a frame of a flat panel display, such as a liquid crystal display or a plasma display. display etc. The frame component is characterized in that at least one joint end thereof has a section that is not perpendicular to the surface of the frame component.

Please refer to FIG. 4a to FIG. 4c to illustrate the joint end structure and the joint method of the present invention with an embodiment. Please refer to FIG. 4 a , the frame components 41 , 42 of a preferred embodiment of the present invention have trapezoidal convex surfaces 411 , 421 in section at the joint end. When the frame component 41 is in coplanar contact with the frame component 42, a notch 80 can be formed near the surface of the frame component 41, 42, as shown in FIG. 4b. Therefore, when the frame components 41 and 42 are welded by butt welding, the molten metal material will fill the gap 80, making the junction a substantially flat surface without bumps, as shown in FIG. 4c.

Please refer to FIG. 5 a , the joint end section of the frame component 51 of the preferred embodiment of the present invention can also be an arc surface 511 . Therefore, when the frame component 51 is in coplanar contact with another frame component 52 having an arc surface 521 , the gap 80 can also be formed, so that the frame components 51 and 52 will not produce bumps at the joint when they are butt welded.

It should be noted that the notch 80 can not only be formed on the upper and lower surfaces of the frame component at the same time, but can also be formed on only one of the upper and lower surfaces of the frame component. As shown in Figure 5b, the frame components 61, 62 only cut an inclined surface on a single surface, so that the cross-section of the joint end is an asymmetric trapezoidal convex surface 611, 621, therefore, when the frame components 61, 62 are in coplanar contact Notches 80 may also be formed. Please refer to FIG. 5 c , in addition, the frame component 71 whose joint end is vertical in section can also be mixed with the frame component 41 , 51 , 61 of the present invention.

Please refer to Fig. 6a, illustrating the frame components of another preferred embodiment of the present invention. The cross-section of the joint end of the frame component 91 is a slope 911 , therefore, the frame component 71 whose cross-section is perpendicular to the joint end can partially overlap with the frame component 91 at the joint end. When the electrode head 100 of the welding equipment is closed up and down for spot welding, a substantially planar junction can be formed, as shown in FIG. 6b. Please refer to FIG. 6 c , the frame components 91 can also be overlapped in pairs, and then joined by spot welding.

To sum up the above, after improving the cross-sectional structure of the joint ends of the frame component of the present invention, it can be welded with relatively low-cost welding equipment. The bonding process is fast and stable, and its bonding strength is similar to that of laser welding.

The above-described embodiments are only to illustrate the technical ideas and characteristics of the present utility model, and its purpose is to enable those skilled in the art to understand the content of the present utility model and implement it accordingly. When it cannot limit the patent scope of the present utility model with it, That is to say, all equivalent changes or modifications made according to the spirit disclosed in the utility model should still be covered within the patent scope of the utility model.
