It includes a step (S160). Hereinafter, the steps of the bezel manufacturing method according to the present embodiment will be described sequentially with reference to FIGS. 2 to 4.

First, as shown in FIG. 2, a pair of metal plates 111 and 112 having a band shape are supplied to the work table 10 in parallel with each other at a predetermined width interval W, and a plurality of metal plates are provided. A material supply step of supplying the 120 to the work table 10 to be positioned between the pair of metal plates 111 and 112 at a predetermined distance interval L from each other is performed (S110).

Here, the pair of metal plates 111 and 112 is formed in a narrow plate shape (band shape) of a metal material of iron and nonferrous metal (for example, aluminum), and is formed from a roll (not shown) of a pair of narrow metal plate materials. It is supplied in a continuous line to the work table 10 while being kept parallel to each other at a predetermined width interval W by the roll method.

In addition, the plurality of metal plates 120 may be formed in a quadrangular shape of the same material (for example, aluminum material) as the pair of metal plates 111 and 112, and may have a predetermined distance L and a flat frame (see FIG. 3). 130 is sequentially supplied to the work table 10 so as to be located between the pair of metal plates 111 and 112 at intervals corresponding to the length of the long side of the opening 133 formed at the center. However, the plurality of metal plates 120 may be supplied to the work table 10 at any position other than the position shown in FIG. 2.

Each of the plurality of metal plates 120 has a pair of inlet holes 121 and 122 formed at both edges adjacent to the pair of metal plates 111 and 112, which are positioned on the work table 10. It is responsible for the function of the positioning hole for the convenience and determination of the position will be described later. However, in the present invention, the number of inlet holes formed in the metal plate 120 is not limited to two, and one or three or more inlet holes may be formed in the metal plate 120. In addition, the position and shape of the inlet hole formed in the metal plate 120 in the present invention is not limited to the bar shown in FIG.

Such a plurality of metal plates 120, before the material supply step (S110), the width (W) of the wider than the roll of the narrow metal plate above (W, of the opening 133 formed in the center in the flat frame 130 of Figure 3 Cutting the wide metal plate material supplied to the continuous line from the roll of the wide metal plate material having a width corresponding to the short side length in the width direction of the supply line using a cutting device or the like. It is provided in a square shape. At this time, the operation of forming a pair of inlet holes 121 and 122 in the rectangular metal plate 120 is also performed. In this embodiment, the pair of inlet holes 121 and 122 are adjacent to the pair of metal plates 111 and 112. It is formed by cutting a part of both edges of the metal plate 120 in a semi-circular shape so as to have a shape drawn inwardly from both edges of the metal plate 120 to be. However, in the present invention, the operation of providing the rectangular metal plate 120 is not limited to the above.

On the other hand, forming a pair of inlet holes (121, 122) at both edges of the metal plate 120, the metal plate 120 on the work table 10 in the process of supplying the metal plate 120 to the work table 10 While positioning the metal plate 120 on the work table 10 is moved along the work line, the position initially determined is changed, so that the joining failure occurs in the subsequent joining step (S120). To prevent this. That is, the metal plate 120 supplied to the work table 10 is engaged with a pair of position fixing means (not shown) provided with a pair of inlet holes 121 and 122 formed at both edges on the work table 10. Since the position is fixed on the work table 10, it can be transported along the work line without changing the position initially determined.

Next, as shown in FIG. 2, a bonding step of bonding the pair of metal plates 111 and 112 and the rectangular metal plate 120 to each other is performed (S120).

Here, when the pair of metal plates 111 and 112 and the rectangular metal plate 120 are transferred along the work line on the work table 10 to reach an area in which the joining device 20 is installed, the joining device 20 is shown in FIG. Both ends of the metal plate 120 are firmly bonded to the inner edges of the pair of metal plates 111 and 112 along the joint WL shown in FIG. 2.

In this case, as the bonding method, at least one of welding, caulking, riveting, or clinching may be applied. Brief description of each bonding method is as follows.

The welding method is an operation in which the metal and the metal are melted and joined to form a single body. Such welding methods include arc welding, gas welding, electric welding, laser welding and the like. The caulking method refers to a work for filling gaps by tapping the overlapping edges or abutting parts with a special caulking well. The riveting method is to overlap a steel plate by inserting a rivet into a hole that is drilled or by folding a non-perforated steel plate, and supporting the head part by tapping it with a machine or a hammer. Types of joints include overlapping joints, butt joints, parallel rivet joints, zigzag rivet joints, and shear face joints. The clinching method, commonly known as button pressing, includes a form of deforming a shape while inserting a prosthesis while pressing a material.

In the present invention, the joining method of the metal plate 120 and the pair of metal plates 111 and 112 may include materials of the pair of metal plates 111 and 112 and the rectangular metal plate 120, required joining performance, work efficiency, and the like. It may be appropriately selected in consideration, and may also be selected other than the above-described bonding methods. However, in the present embodiment, a pair of metal plates 111 and 112 and a joint portion WL of the rectangular metal plate 120 are bonded by using a laser welding method having excellent bonding performance and work efficiency. That is, in the present embodiment, the bonding apparatus 20 is a laser welding apparatus. In this case, the laser welding method refers to a welding method in which a metal is melted and attached to a laser beam.

On the other hand, in general, the longer the length of the continuous welding line in the welding method increases the risk of deformation at the joint, the bezel manufacturing method according to this embodiment is a pair of pull-in formed on both edges of the metal plate 120 Since the joints WL are separated into two parts by the holes 121 and 122, and the length of the continuous welding line is shortened, the risk of deformation in the joints WL can be greatly reduced. It is possible to ensure a more robust welding of the plate (111, 112) and the rectangular metal plate 120. In the present embodiment, the pair of inlet holes 121 and 122 formed at both edges of the metal plate 120 are positioning holes for determining and fixing the position of the metal plate 120 on the work table 10 as described above. Function to reduce the risk of deformation at the joint (WL) by shortening the length of the continuous welding line when welding a pair of metal plates 111 and 112 and the rectangular metal plate 120 to each other. In charge.

Next, as shown in FIG. 2, the predetermined cutting areas A, B, and C, including the portions where the inlet holes 121 and 122 of the metal plate 120 are formed, are cut in both directions in FIG. 2. The cutting step of providing a flat frame 130 (hatched area in one direction in Figure 2) is performed (S130).

Here, when the pair of metal plate (111, 112) and the rectangular metal plate 120 is bonded to each other along the work line on the work table 10 to reach the area where the cutting device 30 is installed, cutting device 30 is cut along two cutting lines CL1 and CL2 shown in dashed lines in FIG. Accordingly, the predetermined cutting areas A, B, and C including the portions where the inlet holes 121 and 122 of the metal plate 120 are formed are cut into scraps, and one metal plate 120 is divided into two parts. Is divided into a planar frame 130 is provided with a rectangular opening 133 is formed in the center.

Next, as shown in Figure 3, trimming step of trimming the outer rim 132 and the inner rim 131 of the planar frame 130 to match the dimensions and shape of the desired planar frame 130 (S140) ) Is performed. However, the present invention may omit the trimming step S140 as described above.

Next, as shown in FIG. 3, the outer edge of the flat frame 130 is bent downward or upward along the predetermined bending line BL, and as shown in FIG. 4, the bent portion of the flat frame 130 is bent. A bending step of forming the 101 and the planar portion 102 is performed (S150).

This bending step (S150), after placing the flat frame 130 prepared through the previous steps (S110 to S140), such as a hydraulic press device (not shown), a rectangular bending line (BL) shown in dotted lines in FIG. A step of forming the bent portion 101 by pressing the edge of the flat frame 130 along. In this case, the hydraulic press device is preferably installed on the work table 10, but may be bent on the flat frame 130 which is installed in a separate work space and is transferred from the work table 10.

Finally, after the above bending step (S150), in order to prevent the rust on the bezel 100 is coated with a waterproof agent (antirust agent), waterproof paint (antirust paint) and the like (S160).

Here, it is effective to coat only the joints (WL in FIG. 2) of the pair of metal plates 111 and 112 and the rectangular metal plate 120 with a waterproofing agent or a waterproof paint, which is typically a pair of metal plates 111 and 112. This is because the risk of rust occurring at the junction (WL) of the metal plate 120 and the square. And, the coating step (S160) is preferably performed after washing the bezel 100. However, the present invention may omit the coating step (S160) as described above.

The bezel manufacturing method according to the present embodiment completes the final product of the bezel 100 for the liquid crystal display panel as shown in Figure 4 by performing the above steps (S110 to S150).

As described above, in the bezel manufacturing method according to the present embodiment, since the scrap to be cut is limited to the predetermined cutting regions A, B, and C in both directions in FIG. Stamping the plate (120) to remove the center portion and bending it to reduce the material cost compared to the conventional manufacturing method for manufacturing the bezel 100, while performing all the processes on a continuous work line It is possible to reduce the overall production cost, including labor costs, by providing a system that is feasible, ie suitable for process automation.

In addition, the bezel manufacturing method according to the present embodiment, unlike the conventional manufacturing method of cutting the metal plate to provide two L-shaped members or four straight members and weld them to produce a flat frame (not shown), Since the flat frame 130 is manufactured by cutting after completion of all the bonding processes, deformation such as twisting or the like is not easily generated in the final product of the bezel 100 manufactured by bending the flat frame 130.

5 is a schematic plan view for explaining a method for manufacturing a bezel for a liquid crystal display panel according to another embodiment of the present invention. Like reference numerals denote the same components as the above-described embodiments. Hereinafter, a description will be given focusing on differences from the above-described embodiment.

Referring to FIG. 5, in the bezel manufacturing method according to the present embodiment, two pin holes 123 and 124 formed through the rectangular metal plate 120 are positioned for positioning instead of a pair of inlet holes 121 and 122. It is substantially the same as the bezel manufacturing method according to the above-described embodiment, except that it functions as a hole.

Here, two pin holes 123 and 124 are formed between a pair of inlet holes 121 and 122 formed at both edges of the rectangular metal plate 120. These two pinholes 123 and 124 serve as a function of positioning and positioning that the pair of inlet holes 121 and 122 were responsible for in the above-described embodiment, and supply the metal plate 120 to the work table 10. While positioning the metal plate 120 on the work table 10 in the process of convenience, while the metal plate 120 is moved along the work line on the work table 10, the initially determined position is changed This is to prevent the bonding failure occurs in the bonding step (S120) to be carried out after. That is, in the metal plate 120 supplied to the work table 10, a pair of position fixing pins (not shown) provided on the work table 10 are inserted into the two pin holes 123 and 124, respectively. Since it is fixed in position, it can be transported along the work line without changing the initially determined position.

However, in the present invention, the number of pinholes formed in the metal plate 120 is preferably two or more in order to prevent the metal plate 120 from being rotated about the center of the pinhole, but the present invention is not limited thereto. Pinholes may also be formed. In addition, the position and shape of the pinhole formed in the metal plate 120 in the present invention is not limited to the bar shown in FIG.

On the other hand, in the present embodiment, unlike the above-described embodiment, since a pair of position fixing means corresponding to the pair of inlet holes 121 and 122 is not provided on the work table 10, a pair of inlet holes ( 121 and 122 do not play a function as a positioning hole. When welding the pair of metal plates 111 and 112 and the rectangular metal plate 120 to each other, the length of the continuous welding line is shortened to the junction WL. It only functions to reduce the risk of deformation.
