Description

  The present invention relates to a metal frame molding apparatus, and more particularly, to a metal frame molding apparatus that saves labor costs and material costs, and can be quickly produced by an integrated operation by automation without producing defective products.

  The prior art will be described below with reference to the drawings. FIG. 5 is a plan view showing a rectangular plane frame used for metal frame molding welded by a conventional technique. FIG. 6 is a plan view showing a number of L-shaped members made from a wide band-shaped metal material according to the prior art. FIG. 7 is a plan view showing the “wrong joining” phenomenon of a square planar frame welded according to the prior art. FIG. 8 is another plane showing the “wrong joining” phenomenon of a square plane frame welded according to the prior art. As shown in FIGS. 5 to 8, the metal frame molding method for LCD or LED panel disclosed in Patent Documents 1 to 3 has a large number of wide band-shaped metal materials 8 on a press board in order to reduce material costs. After pressing the L-shaped member 81 (see FIG. 6), the two L-shaped members 81 are joined to each other. The two planes 9 (see FIG. 5) to be provided to the LCD or LED panel metal frame 7 (see FIG. 4) are manufactured by welding the two joining portions 91 to each other. Next, it is moved onto another press board, and the position of the imaginary line frame 93 in FIG. 5 is press-molded to finally complete the metal frame 7 for the LCD or LED panel.

  The conventional metal frame 7 described above uses a large number of L-shaped members 81. When the wide band metal material 8 is pressed, two triangular material pieces 82 on both sides of the tip, a large triangular material piece 83 in the center of the end (see FIG. 6), and a large number of small triangular material pieces 84 on both side edges are cut off. Just do. When welding the rectangular flat frame 9, the material cost of the area of the large opening 92 (see FIG. 5) can be saved. As described above, wasteful waste of materials can be reduced, and material costs can be greatly saved. However, when the two L-shaped members 81 are joined to each other and welded as in the rectangular plane frame 9 (see FIG. 5), the two joining portions 91 as shown in FIGS. A metal frame for an LCD or LED panel that meets the requirements cannot be molded because the indentation or “wrong bonding” phenomenon is very likely to occur. Producing defective products can only be done by recycling and reusing waste metal, resulting in a large loss.

  Recently, Patent Document 4 discloses a relatively quick method of forming a metal frame, but this is merely a combination of a press device and a welding device. A welding device is disposed under the press table of the press device. An opening is provided in the press table, and a welding gun is provided for welding at the contact portion of the two L-shaped members assembled on the press table. Although this method certainly seems to be able to shorten the time required for fabrication, it still has the following three problems.

First, since it is necessary to weld an L-shaped member by placing a welding device under a press stand of the press device, it takes a lot of time to design the die. Secondly, a welding apparatus is placed under the press table and the L-shaped member is welded, and then pressed to form the rectangular flat frame 9 having the opening 92 in the center. The metal shown in FIG. The frame 7 cannot be pressed directly. In order to press the metal frame 7, it must be moved to the press device or press stand and pressed. For this reason, it is difficult to shorten the time required for manufacturing. Third, the welding performed on the press table is not welded to the contact portion of the L-shaped member, but the left and right sides are respectively welded to the ends of the strip-shaped metal material having V-shaped openings on the press table. To do. Since there is no front / rear and left / right positioning device on or around the press table, the "wrong joining" phenomenon that protrudes outward or dents inward during welding is shown in FIGS. Often happens. In addition to this, upper and lower “wrong joining” phenomenon is more likely to occur. As described above, it was concluded that the idea was not just practical, but merely a snake foot, which led to a situation in which defective products were made, rather than shortening the time required for manufacturing. Therefore, there has been a demand for a method for forming a metal frame for an LCD or LED panel that reduces the production cost.

  An object of the present invention is to provide a metal frame forming apparatus that can be quickly produced by an integrated operation by automation, which saves labor costs and material costs and is difficult to produce defective products.

  In order to achieve the above object, the present invention provides a metal frame forming apparatus. The metal frame molding apparatus of the present invention comprises a material placement device, a material transfer device, a welding device, an automatic arm device, and a molding device. The material placement device includes a material placement shelf that is placed in the forefront and places a metal material roll. The material transfer device is arranged at one end in the direction in which the band-shaped metal material comes out of the material arrangement device, and is composed of a leveling device, a traction device, and a transfer device in order. The two band-shaped metal materials of the metal material roll are pulled by the pulling device, sent to the leveling device and flattened, and then welded to the edges at both ends of the rectangular metal member by the welding device to form the band-shaped molding material. Then, it is sent onto the molding device by the transfer device, and cutting and molding are performed. The welding device is arranged around the material transfer device, and includes a welding machine having two welding guns and two electromagnetic welding stands. The automatic arm device is also arranged around the material moving device, and includes an automatic arm device main body having a robot arm for picking up and placing material by a suction cup, and a material placement table. Although the rectangular metal members are arranged so as to be stacked together on the material arrangement table, they are arranged on the electromagnet welding table in turn by the robot arm of the automatic arm device main body, and the rectangular metal members are arranged by the two welding guns of the welding device. The edges at both ends and the inner edges of the two band-shaped metal materials are welded to form a band-shaped molding material. The molding device is a continuous press type molding device that is arranged so as to be connected to the rear part of the material transfer device, and is a “ladder-like” strip-shaped molding material sent by the transfer device of the material transfer device. After being cut and cut like a flat frame, it is shaped like a strip metal material.

  The metal frame molding apparatus of the present invention is different from the conventional metal frame molding apparatus in that all materials are used “almost completely”, so there is no waste and the material can be saved greatly. In the metal frame molding, the “wrong joining” phenomenon does not occur, and the production of defective products can be prevented. In addition, when the metal frame molding apparatus of the present invention molds a belt-shaped metal material, the production speed is fast and labor costs can be saved by an integrated operation by a machine.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a metal frame forming apparatus according to an embodiment of the present invention. FIG. 2 is a plan view showing a strip-shaped molding material welded by a metal frame molding apparatus. FIG. 3 is a plan view showing the flat frame cut by the metal frame forming apparatus. FIG. 4 is a perspective view showing a state in which the flat frame of FIG. 3 is directly pressed and made into a metal frame. As shown in FIGS. 1 to 4, the metal frame molding apparatus according to the embodiment of the present invention includes a material placement device 1, a material transfer device 2, a welding device 3, an automatic arm device 4, and a molding device 5. The material placement apparatus 1 includes material placement shelves 11 and 12 that are placed at the forefront and on which metal material rolls 60a and 60b are placed. The material transfer device 2 is arranged at one end in the direction in which the strip-shaped metal materials 6 a and 6 b come out from the material arrangement device 1, and includes a leveling device 21, a traction device 22, and a transfer device 23 in order. The two strip-shaped metal materials 6a and 6b of the metal material rolls 60a and 60b are pulled by the traction device 22 and sent to the leveling device 21 to be flattened. The belt-shaped molding material 6 (see FIG. 2) is formed by welding. Then, it is sent onto the molding device 5 by the transfer device 23, and cutting and molding are performed. The welding device 3 is arranged around the material transfer device 2 and includes a welding machine 30 having two welding guns and two electromagnet welding stands 31. The automatic arm device 4 is also arranged around the material moving device 2 and includes an automatic arm device main body 40 having a robot arm 42 for picking up and placing material by a suction cup, and a material placement table 41. The rectangular metal members 61 are arranged so as to be stacked together on the material arrangement table 41, but are arranged on the electromagnet welding table 31 in order by the robot arm 42 of the automatic arm device main body 40, and the two of the welding devices 3 are arranged. The edges of both ends of the rectangular metal member 61 and the inner edges of the two strip-shaped metal materials 6a and 6b are welded and joined to form the strip-shaped molding material 6 (see FIG. 2). The molding device 5 is arranged so as to be connected to the rear part of the material transfer device 2, and is a continuous press mold forming device composed of a cutting die 51 and a molding die 52. The strip-shaped molding material 6 (see FIG. 2) is received and cut into a plane frame 60, and then molded into a strip-shaped metal material 7 (see FIG. 3).

  In the metal frame molding apparatus of the present invention, when the cutting die 51 of the molding apparatus 5 performs the cutting operation of the strip-shaped molding material 6, the first cutting is performed at the position of the imaginary line 612 shown in FIG. The square metal member rear end 611 of the rectangular metal member plate 610 of the square metal member 61 at the tip, the band metal material leading ends 62a and 62b of the two band metal materials 6a and 6b, and the square metal member of the square metal member 61 at the end. Other than cutting and removing the rear half (not shown) of the plate body 610 and the end portions of the band-shaped metal material tips 62a and 62b of the two band-shaped metal materials 6a and 6b, the other portions are squares shown in FIG. A plane frame 60 having a large opening 601 at the center shown in FIG. 3 is formed in order by cutting at the position of the imaginary line 612 at the center of the metal member 61. Next, it is directly pressed into the molding die 52 of the molding apparatus 5 to become a strip-shaped metal material 7 (see FIG. 4) of the LCD or LED panel. All materials are used "almost completely", so there is no waste and material savings unlike the conventional metal frame forming apparatus described above. Further, when the two strip metal materials 6 a and 6 b are welded to the edges at both ends of each square metal member 61, the two strip metal materials 6 a and 6 b are simultaneously transported in parallel to the material transfer device 2. Each quadrangular metal member 61 is accurately placed on the two electromagnet welding bases 31 of the welding apparatus 3 by the automatic arm device 4, attracted and fixed by the two electromagnet welding bases 31, and then joined by welding. Therefore, the “wrong joining” phenomenon does not occur, and it is novel and practical, unlike the conventional metal frame molding apparatus. In particular, when the metal frame molding apparatus of the present invention molds the strip-shaped metal material 7, the production speed is high and labor costs can be saved by an integrated operation by a machine.
