Description

1331891 IX. Description of the Invention: The present invention relates to a method for manufacturing an outer casing for an LCD module (hereinafter referred to as an LCD module housing) and an outer casing manufactured thereby, and more particularly, The manufacturing process of the outer casing can be simplified, the consumption of unnecessary materials can be reduced, and the production can be revolutionized by the existing production mode. [Prior Art]

In general, the LCD module housing is used to support the function of the LCD module in the outer contour portion of the LCD module in which the LCD panel is mounted. It is also called a top chassis and a bezel frame. ) and other parts. Such an LCD module case has a characteristic that it must be precisely manufactured by a die-working operation using a metallic material, and the outer side of the LCD module is precisely surrounded. However, the conventional LCD module housing is manufactured through various complicated steps in the mold operation.

An example of the manufacturing steps of the conventional LCD module housing is reviewed, which is performed as shown in Figs. 1(a) to (f). That is, the manufacturing steps of the conventional LCD module housing are performed in each of the steps performed to pass the outer frame of the mold through each of the necessary single-shot molds. The manufacturing steps of this prior art are specifically described as follows. As shown in Fig. 1(a), the steel sheet is drawn into a roll-shaped sheet, and the steel sheet is pulled by the first mold machine, and a compound operation is performed as a single step. The composite step performed in the above-mentioned Fig. 1(a) is performed by winding the roll 114900.doc in a flat state, and removing the central flat plate 4 which is unnecessary inside the portion where the L is bent and the 2 is bent. + At the end of the beveling and punching step performed in the i(d) step on the right, the remaining part of the beveling and punching step by the fourth die machine will be stamped by the die processing. The tapping step shown in Fig. 1 (4) is performed by the fifth die machine so that unnecessary metal chips are removed from the portion and removed by screwing or the like. When the tapping step or the like is completed by the mold step of the other step, the final sixth mold machine is used for precise finishing to manufacture a desired finished product of the LCD module casing. : The manufacturing method of the conventional LCD module housing formed by such complicated steps requires at least six expensive mold machines to perform the work. From the point of view of yue and sigh investment, it is necessary to set a number of high-priced mold machines, not only to use ff to be high, but also to (4) There is a problem in the shape of the mold to put the 'work in accordance with the work step' so that the worker who should operate or manage the mold has many problems. In addition, in the step of FIG. 1 (4), in order to make the LCD module, only the outer frame other than the front part of the visible module is fixed (4)

The outer frame is punched, and the unnecessary portion is punched, that is, the portion where the inner portion is not required for the E-angle form is subjected to (4) cutting and processing. At this time, the unnecessary part that is cut off will have more frame problems than the frame frame. However, the resources are returned. In addition, the above-mentioned parts that are cut off will be recycled by the resources, and the operation is actually carried out. There will be a problem that the tablet must be added again. Therefore, in the conventional method of manufacturing an LCD module housing, armor requires not only a large-sized mold machine but also a mold, and a robot for moving the robot between the machines. One mold is mechanically transported to the next mold machine, so there is a problem that a large amount of equipment investment costs are required. In addition, there is a problem that the management cost increases due to the use of one side, and the inner portion which is discarded by punching and cutting in order to obtain the square frame having the inner side opening, and thus many problems such as the cost of the steel sheet raw material may be incurred. [Explanation] [Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a method of manufacturing an LCD module housing and an outer casing manufactured thereby, when manufacturing the housing By simplifying the steps, the waste of unnecessary flat materials can be eliminated. [Means for Solving the Problem] In order to achieve the above object, the manufacturing method of the LCD module casing of the present invention has the following steps: a manufacturing process of the linear frame, and a frame of the lCd module casing using a progressive type mold The press processing is continuously performed in a straight line, and the bending process is performed by bending the linear frame into a horizontal frame and a vertical frame, and a welding step of abutting the bent frames to form a square frame, and then abutting each other The ends are fixed in one piece. H4900.doc 1331891 2〇b directly chamfers, so it can increase the speed of the punching step of the mold. Further, after the linear frames 2a, 20b are formed into the horizontal frame and the vertical frame by the bending step, the two sets of the horizontal frame and the longitudinal frame are welded to each other by a bonding means such as laser welding in the next step. By fixing them to each other, it is easy to manufacture a four-corner frame structure of a smooth shape. On the other hand, as shown in FIG. 4 and FIG. 5, of course, when the linear frames 20a and 20b are driven by the continuation type mold, a plurality of the notched portions 26 for bending are formed, and the bent portion is folded. After the formation in a plurality of stages, the abutting portions of each other are integrally fixed by a bonding means such as laser welding to manufacture a square frame. At this time, the bent portion of the notched portion 26 for bending is welded to the entire surface at the joint portion at the two joints, and when the bent portion is welded at the four places, a four-cornered frame with a reinforcing fixing force can be produced. In other words, when the linear frames 20a and 20b are bent into a plurality of sections to form a four-corner frame, it is possible to laserly weld only the contact portions between the one frame and the other end of the frame. The portion where the bent portion is bent is also subjected to laser welding, and the reinforcing strength of the bent portion is further enhanced to provide a stronger four-corner frame. On the other hand, as shown in Fig. 6, the hole portion 28 may be formed at a boundary portion where the linear frames 20a and 20b are bent when the L is bent (see the figure, that is, in the present embodiment, 'being the gap for bending) The inner end of the portion 26 is formed with an elliptical hole portion 28'. When the L is bent, the linear frames 2a, 2b are bent so that the boundary portion of the bend passes through the hole portion 28. After that, as shown in Fig. 6 b), the linear frames 20a, 20b are bent in a shape of 114900.doc -12 - 1331891 instead of the linear frame by the notched portion 26 for bending. It is a matter of course that a step of confirming the right angle of the processed square frame and whether or not the distortion is generated may be additionally added. [Effect of the Invention] Therefore, as described above, the LCD module casing and the LCD module using the same are used. When the frame is manufactured, the steps can be simplified, and the consumption of unnecessary flat materials can be eliminated.

In addition, since the metal sheet formed in the form of a roll is automatically assembled only to the one pair of molds of the continuous type at the time of manufacture of the outer casing, and the linear frame is immediately produced, the material cost can be saved by 50% or more. It can bring great economic benefits. Since the continuation type mold has the fastest processing speed in particular, the processed linear frame can be bent immediately in the next step, and then only the welding step which can be fixed to each other is integrated, thereby greatly improving The efficiency of production speed.

The effect of the present invention is not limited to the above, since a large number of mold machines are not required, and only a continuous type of boring mold is required, so that the equipment investment cost required for setting the mold is higher than that of the conventional one. Reduce the effect to 7〇 to 80%. In addition, since only one pair of mold machines is used, when a plurality of mold machines are generally used, it is not necessary to separately transport the processed flat materials between the molds to the next step of the robot apparatus or defective product confirmation. The device etc. 'is therefore extremely economical. [Simple description of the map]
