Description

  The present invention relates to a method for manufacturing a frame-shaped component for a display device.

  A liquid crystal display device, which is a type of display device, is roughly configured to have a backlight device as an external light source assembled on the back side of a liquid crystal panel for displaying an image. The liquid crystal panel is held in a state of being sandwiched between a frame-shaped bezel that is arranged on the front side and surrounds the display area, and a frame-shaped frame that is a part of the backlight device arranged on the back side.

  When manufacturing these bezels and frames, the base material of the metal plate is punched into a predetermined shape by a mold and subjected to bending processing, but if these frame-shaped parts are taken out from the base material as they are, Since the inner area is wasted, material removal is worsened. In order to cope with this problem, for example, it is conceivable to adopt a method in which a frame-shaped part is configured by connecting a plurality of divided members, and each divided member is taken out from the base material.

In addition, what was described in the following patent document 1 is known as an example of what divided the frame-shaped component into the some division member.
JP 2002-311417 A

  When dividing the frame-shaped component, for example, if the dividing member is composed of only two types of long and short straight members, material loss when punching from the base material can be almost eliminated. However, when the straight members are connected to form a frame-like component, the overall strength may be insufficient.

  Therefore, it is conceivable to use a “U” -shaped member in which a pair of protrusions protrude from both ends of the straight part as the dividing member of the frame-like component. If a straight member is connected to this “U” -shaped member to form a frame-shaped part, sufficient strength can be obtained. However, when the “U” -shaped member is taken out from the base material, there is a problem that the material removal deteriorates because the region between the two protrusions becomes a material loss.

  The present invention has been completed based on the above circumstances, and an object thereof is to reduce the cost while maintaining high strength.

  As a means for achieving the above object, the invention of claim 1 constitutes a display device, and is formed in a frame shape surrounding the display area of the display component, and can hold the display component. In the manufacturing method of the frame-shaped component, the frame-shaped component is formed by connecting the divided members taken out from the plate-shaped base material, and the divided members are arranged at both ends of the straight portion. A high-strength member having a shape in which a pair of protrusions project from the portion in the same direction and in a direction substantially perpendicular to the axial direction of the straight portion, and a straight member connected to the protrusion of the high-strength member; When the high-strength member and the straight member are taken out from the base material, the straight member is taken out using at least a part of a region between the two protrusions in the high-strength member. Have

  According to a second aspect of the present invention, the arrangement of the high-strength member and the straight member in the base material is set so that the straight member is substantially parallel to the straight portion of the high-strength member. It has the characteristics in the place.

  According to a third aspect of the present invention, the arrangement of the high-strength member and the straight member in the base material according to the second aspect is such that a part of the straight member is more than a protruding end of the two protrusions in the high-strength member Is also characterized by being set to project outward.

  According to a fourth aspect of the present invention, the arrangement of the high-strength member and the straight member in the base material is substantially the same as the protruding end of the protrusion in the high-strength member. It is characterized by being set to be flush.

  The invention according to claim 5 is characterized in that in the apparatus according to any one of claims 1 to 4, a plurality of the straight members are taken out from a region between the protrusions in the base material. .

  According to a sixth aspect of the present invention, in any one of the second to fifth aspects, the length dimension of the region between the protrusions in the base material is an integer of the length dimension of the straight member. It is characterized by being set to about twice the size.

  According to a seventh aspect of the present invention, when the high-strength member and the straight member are taken out from the base material according to any one of the first to sixth aspects, the arrangement of the high-strength member and the straight member is adjusted. It is characterized in that the base material is punched out by a mold having a different shape.

<Invention of Claim 1>
Since the straight member is taken out using at least a part of the region between the protrusions of the high-strength member, material removal from the base material is improved accordingly. Thereby, cost reduction can be achieved, keeping the intensity | strength of a frame-shaped component high.

<Invention of Claim 2>
Since the straight member is arranged so as to be substantially parallel to the straight portion, the area between the two protrusions can be used effectively compared to the case where the straight member is parallel to the protrusions. Good material removal can be achieved.

<Invention of Claim 3>
The material loss that occurs between the outer end of the straight member and the protruding end of the protruding portion of the high-strength member should be reduced compared to, for example, the outer end of the straight member disposed inside the protruding end of the protruding portion. Therefore, it is possible to further improve the material removal.

<Invention of Claim 4>
Since no material loss occurs between the outer end of the straight member and the protruding end of the protruding portion of the high-strength member, the material removal can be further improved.

<Invention of Claim 5>
A reserve for the straight member can be formed by using the region between the two protrusions. The spare straight member is used when, for example, the straight member is lost or the straight member is damaged in the manufacturing process of the display device. According to the present invention, the manufacturing cost can be reduced as compared with a case where a spare straight member is manufactured separately.

<Invention of Claim 6>
Since the area between the two protrusions can be utilized almost without waste, the material removal can be further improved.

<Invention of Claim 7>
Since both a high-strength member and a straight member can be obtained with one type of mold, the mold cost can be reduced, and the cost can be further reduced.

Both positioning protrusions 45 and 46 project to the back side (the liquid crystal panel 11 side) and have a circular section and a tapered shape, and are formed by knocking out the holding section 28 from the front side. Further, a second screw hole 47 through which the second screw 39 can be screwed is formed in the peripheral wall portion 29 of the protrusion 35 of the high-strength member 32.

  The liquid crystal display device of the present embodiment has the above structure, and the manufacturing method thereof will be described next. First, when manufacturing the bezel 13, the divided members 32 and 33 obtained by performing a work of punching the divided members 32 and 33 from a base material M made of a large metal plate with a mold (not shown) are roughly used. Work to connect.

  Here, the arrangement of the high-strength member 32 and the straight member 33 in the base material M will be described. As shown in FIG. 7, the two straight members 33 are arranged in the region between the protrusions 35 in the high-strength member 32. It has come to be. Specifically, the straight members 33 are in a posture substantially parallel to the straight portion 34 of the high-strength member 32, and two straight members 33 are arranged in series in a region between the protrusions 35. The side surface of the straight member 33 opposite to the straight portion 34 of the high-strength member 32, that is, the outer end 33 a is disposed on the inner side (closer to the straight portion 34) than the protruding end 35 a of the protruding portion 35. That is, the entire straight member 33 is completely stored in the region between the protrusions 35. The distance between the straight member 33 and the straight portion 34 of the high-strength member 32 is set to be substantially the same as the distance between the straight members 32 and the distance between the straight member 33 and the adjacent protrusion 35. Yes. The base material M is punched with a mold having a shape corresponding to the arrangement of the high-strength member 32 and the straight member 32.

  Note that the high-strength member 32 and the straight member 33 shown in FIG. 7 have a developed shape, and the high-strength member 32 and the straight member 33 are shown in FIG. 5 by bending or drawing the developed shape. Molded into a shape. Various processes such as bending and drawing may be performed at the same time as punching with a mold, or may be performed again after punching in a developed shape with a mold. May be.

  By the way, when the base material M is punched by the above-described mold, two straight members 33 are obtained from the region between the protrusions 35 in the high-strength member 32, and therefore one straight member 33 of them is obtained. Can be reserved. Thereby, even if the straight member 33 is lost or damaged in the assembly process of the bezel 13 or the liquid crystal display device 10 described below, the spare straight member 33 can be used.

  Then, the operation | work which connects each obtained division member 32 and 33 is performed. From the state shown in FIG. 6, both connecting pieces 36 and 37 of the straight member 33 are directed to the back side of the protrusion 35 of the high-strength member 32, and positioning protrusions 45 and 46 corresponding to the positioning holes 41 and 42 are provided. Try to fit. At this time, since the positioning hole 42 on the distal end side of the first connecting piece 36 is oval, the above-described fitting operation can be easily performed. As a result, the first insertion hole 40 is aligned with the first screw hole 44 and the second insertion hole 43 is aligned with the second screw hole 47, so that the first screw 38 and the second screw 39 are subsequently tightened. The high-strength member 32 and the straight member 33 are fixed in a connected state. By performing the above-described connecting operation at the four divided positions of the bezel 13, as shown in FIG. 1, a substantially frame-shaped bezel 13 is formed as a whole. Since the two high-strength members 32 are used for the bezel 13, sufficient strength is obtained.

  The liquid crystal display device 10 is assembled using the bezel 13 obtained as described above. After the liquid crystal panel 11 is placed on the frame 14 of the backlight device 12 from the state shown in FIGS. 1 and 2, the bezel 13 is directed from the front side. As a result, the peripheral edge of the liquid crystal panel 11 is sandwiched between the frame 14 on the back side and the bezel 13 on the front side, and the screws B are tightened so that they are integrated as shown in FIGS. Hold on. The assembly of the liquid crystal display device 10 is completed as described above.

  As described above, according to the present embodiment, when the high-strength member 32 and the straight member 33 are taken out from the base material M, the straight portion is utilized by utilizing a part of the region between the protrusions 35 in the high-strength member 32. Since the member 33 is taken out, the material removal from the base material M is improved by the amount using the region between the two protrusions 35, and the cost is reduced while keeping the strength of the bezel 13 high. Can do.

  The arrangement of the high-strength member 32 and the straight member 33 in the base material M is set so that the straight member 33 is substantially parallel to the straight portion 34 of the high-strength member 32. Therefore, the straight member is assumed to be parallel to the protrusion. Compared with the case where it did, the area | region between both the protrusions 35 can be utilized effectively, and the material removal from the base material M can be made favorable.

  In addition, since the two straight members 33 are taken out from the region between the protrusions 35, a reserve for the straight member 33 can be obtained. As compared with the case where a spare straight member is separately taken out from the base material, the manufacturing cost can be reduced.

  In addition, since the length dimension of the region between the protrusions 35 is about twice as long as the length of the straight member 33, the region between the protrusions 35 is almost completely removed when the two straight members 33 are taken out. It can be used without waste, and the material removal can be further improved.

  In addition, since the base material M is punched with a mold having a shape that matches the arrangement of the high-strength member 32 and the straight member 33, both the high-strength member 32 and the straight member 33 having different shapes depending on one type of mold are obtained. Can reduce the mold cost.
