New description: [New technical field] This creation is about a frame component, especially a frame component used to form a flat display frame, which is suitable for welding methods other than laser welding. Technology] Flat-panel displays are widely used in a variety of electronic products because of their slimness, low power consumption, and relatively low radiation pollution. Taking a liquid crystal display as an example, the liquid crystal display module mainly comprises a main component such as a liquid crystal display panel and a backlight module, and the above components are fixed by a plurality of frames to form a complete liquid crystal display module. Referring to Figures la to lc, the process steps of the conventional frame will be described. First, the metal coil or sheet is cut into a metal plate 11 of an appropriate size. Next, a desired window hole 12 is formed in the central portion of the metal plate 11 by a processing step such as cutting or punching. Finally, a subsequent processing step such as hemming is performed to form the frame 13 as shown in Fig. 1c. In the above process, the metal material of the same area which is formed when the window hole 12 is formed is not highly utilized, and is even regarded as waste material, so that the material cost of the frame 13 cannot be effectively reduced. In view of the above problems, there has been a production method in which a plurality of constituent members are joined into a combined frame. As shown in Fig. 2a, the frame 2 is formed by the relative engagement of two L-shaped frame members 21. As shown in Fig. 2b, the L-shaped frame constituent member 21 can be efficiently cut from the metal material 22 to reduce waste generation. Referring to Figures 3a to 3d, in addition to the L-shaped frame component members, there are a plurality of different frame members, such as an equilateral U-shaped frame component member 31, an equilateral U-shaped frame component member 32, and a long The strip type frame constitutes members 33, 34. Alternatively, the frame members of the two different shapes may be joined into a frame, for example, the M318305 is formed by combining two L-shaped frame members 35 and one elongated frame member member 36 into a frame as shown in Fig. 3d. Regardless of the type of frame member used to form the frame, it is inevitable that the joining process requires the joining of the frame members. At present, the purpose of joining is achieved by laser welding or by riveting. However, laser grafting equipment is costly and requires a relatively professional technician to operate, which is also a burden on manufacturing costs. However, in the manner of riveting the punching machine, the joint strength is less than that of the laser welding, the processing steps are relatively complicated, the productivity is poor, and the precision of the riveting is difficult to control, so that the frame joined by the riveting method is not The pass rate is higher. In summary, how to join the combined frame at a relatively low cost, and the joint strength and reliability are similar to the way of laser welding, which is the goal that is currently in great need. [New content] For the above problems, this One of the object of the invention is to provide a frame constituent member which is improved in the structure of the joint end portion so that it can be joined by a welding apparatus having a low equipment cost, and the joint strength is similar to that of the laser welded joint. In order to achieve the above object, the frame constituent members of an embodiment of the present invention are used to form a flat display frame. The frame constituent member is characterized in that the cross section of at least one of the joined ends is not perpendicular to the surface of the frame constituent member. In the following, the specific embodiments and the accompanying drawings are explained in detail, and it is easier to understand the purpose, technical content, characteristics and effects achieved by the present invention. M318305 [Embodiment] The frame of the creation is made of metal material, and its appearance can be U-shaped, non-(U) U-shaped or long-shaped, etc., to form a flat-panel display such as t-display or electric_display. . The frame constituent member is characterized in that the section to the >, - δ end portion is not perpendicular to the surface of the frame constituent member. The structure of the joint end and the joining method of the present invention will be described by way of example with reference to Figs. 4c'. In the first embodiment of the present invention, the frame member member 41 of the preferred embodiment of the present invention has a trapezoidal convex surface 411 '421. When the frame constitutes the frame, and the members 42 are in coplanar contact, a notch 80 can be formed near the frame member 4, as shown in Fig. 4b. Therefore, in the case of the welding method ==„牛41, 42°, the molten metal material will fill the gap 8〇, so that the joint is in a substantially flat plane without bumps, as shown in Fig. 4c. The joint of the fine-grained frame group member 51 may be a curved surface 511. Therefore, when the frame-constituting member 51 is in coplanar contact with the frame member 52 of the other eight frame, σ 8° 'frames the component member ^When welding the material =:::::: The lower surface needs the notch 8G not only can be combined with the _ pure frame group « upper and lower recording surface, but also can be formed only in the frame group shown in Figure 5b, the frame constituent member 61, 62 = one of them: the section 2 of the joint end is similar to a bevel on the surface of the earlier one, so that the member 61, the flat side is connected to the other side = the trapezoidal convex surface 611, 621, therefore, the frame group frame component 41, 5b 61 mixed solid member 71 can also be described with reference to Fig. 6a, the present invention is described. The joint end portion of the frame constituent member 91 is a frame structure of the parent embodiment and the Tianping sighs The electrode tip 1 〇〇 upper and lower closed spot welding M318305 forms a substantially planar joint, as shown in Figure 6b, the frame constituent member 91 can also Correspondingly, the overlap, and then the point-by-point method, =c. 'c is the frame-level component that has been improved. After the construction, the cross-section process of the welding equipment at a relatively low cost is not only fast, but And the combination of the money and the material is close to the purpose of the second object: the embodiment is only for explaining the technical idea and characteristics of the creation: the person who is interested in the skill can understand the content of the creation and The 2nd can't limit the scope of the patent of this creation, that is, the production of the original = true = Kobe W (four) or modification, should still be covered in this creation = [Simple diagram of the diagram] Figure la to Figure lc is a conventional preparation Figure 2a to Figure 2b are schematic views of a conventionally prepared combination.
