Description

frame for display panel

technical field

The utility model relates to a frame of a display panel, in particular to a novel frame of a display panel, which automatically corrects tolerances through the concave-convex positioning parts guided between the joint surfaces of the frame components, thereby improving the qualified rate of products and reducing costs .

Background technique

In general thin displays such as LCD displays, the metal frame used to fix the panel and backlight module is usually stamped and formed with a large-area metal plate material, that is, the entire piece of metal plate material is stamped in one piece, and the required frame is retained. The rest are completely eliminated. The advantage of the traditional forming method is that no positioning is required, but the disadvantage is that it consumes materials and relatively high cost, and the force of the integral stamping forming method is too concentrated, resulting in poor flatness.

In order to save materials and reduce costs, it is known that many relevant documents have been proposed to improve the shortcomings of traditional technologies. For example, Figure 1 shows the document No. M260081 of Taiwan, China, which discloses an "improved LCD panel frame", which It mainly includes a frame body 24', the frame body 24' is composed of two L-shaped workpieces 22' butted, and a bending part 28' is provided in the vertical direction around the outer frame of the frame body 24' to form a side surface department. First punch out a plurality of L-shaped workpieces from metal materials, and then process them after combining them into a frame, which can effectively use materials, save costs and avoid waste.

In addition, as shown in FIG. 2 , there is the document No. M324588 of Taiwan, China, which discloses a preparation device for stamping the panel frame above. As shown in the figure, the metal materials 5', 5" from two opposite directions are transported to a stamping table 411' respectively through the feeding unit to prepare two L-shaped components 51', 51" and make them align and combine, corresponding to A predetermined welding area 52' is formed on the joint surface of the L-shaped members 51', 51", and an opening 411a' is formed on the stamping table 411' corresponding to the predetermined welding area 52'. The laser welding machine welds the predetermined welding area 52' through the opening 411a' from below the punching table 411'. In this way, the metal materials 5', 5" are directly stamped and assembled on the punching table 411' And welding, and then stamping, the panel frame can be produced quickly.

The above-mentioned disclosed documents use L-shaped workpieces for docking, although some materials can be saved and some costs can be reduced. However, those skilled in the art can understand that there is no positioning reference between the joint surfaces of the L-shaped workpiece, and the relative joint between the two is not easy to locate accurately. Moreover, the two feeding units are conveyed from opposite directions, and the centerlines H', H" of the two are offset by a distance D' from each other, and the joint level points V', V" are not easy to accurately control. Therefore, in addition to the tolerance of the workpiece itself, the manufacturing process of the above-mentioned panel frame also includes equipment tolerances and level tolerances. Due to the influence of accumulated tolerances, the joint surface and flatness of the product are not good, and even the pass rate of the product is affected.

Utility model content

The main purpose of the utility model is to provide a frame for a display panel, which is used to solve the problem of low product qualification rate in the prior art due to the influence of equipment tolerance and total tolerance in the manufacturing process.

In order to achieve the above, according to the utility model, there is provided a frame for a display panel, which at least includes a pair of vertically intersecting L-shaped frame members, and the two are relatively joined to form a rectangular frame with a storage space, which is used to configure the panel and backlight modules etc. Wherein, on the joint surfaces of the frame member and the frame member, concave and convex positioning parts guiding each other are stamped and mortised together.

When the L-shaped frame member of the present invention is in the unfolded state in the plane direction, the concave-convex positioning parts of the joint surfaces of the two are butted with each other from opposite directions, so that it can be accurately positioned and easy to assemble, and the concave-convex positioning through the mutual guidance The position difference is automatically corrected by the part, which can reduce the problem of equipment tolerance. Even if there is a tolerance in the equipment, it can be automatically corrected through the concave-convex positioning part guided by each other, thus solving the problem of equipment tolerance and total tolerance in the production process of the prior art The influence of the influence leads to the problem that the qualified rate of the product is not high.

In addition, the butt joint method of the L-shaped frame members of the present invention can reduce material loss and fully release the stress. After joining, the joint surface is welded and stamped along the predetermined stamping line, so the flatness after forming Very good.
