Light box material: keel: made of wood strips, angle iron or aluminum alloy profiles. Light source: two groups of fluorescent tubes. Panel: plexiglass color plate or pvc color plate. Support: triangular iron frame. Common tools of light box: electric drill, cross screwdriver, screwdriver, hacksaw, wood saw, shovel hammer, pliers, small nails, latex, hook knife, wire saw, plexiglass. Key points of operation technology: design: according to the customer's design requirements, the size, color and font of the light box are arranged in primary and secondary order, and the changes of pictures and texts should be placed horizontally and vertically. In addition, it depends on the brackets made at the installation site. Based on this design, the size, font and color of each word are calculated and searched. Keel: generally hexahedron. Material: 20×20 or 30×30. Angle iron: conditional self-processing, unconditional external processing. Wood: 2×2 cm square timber is used for nail rack. Blanking: four pieces in length and four pieces in width, with length, width and less than 0.5cm = wood length. Saw 2× 1 tenon at both ends, paste it with white latex and nail it. Thickness dimension minus two material thicknesses +0.5 = thickness length. Then put on white latex and nail it. Aluminum material: the aluminum alloy material of the ground cabinet is the same height, width and length. 45-degree angle saw, connected with plug-in. Lighting: Generally, two or three fluorescent tubes are used. 40W 1.2 long lamp tube with 1.3m light box. The 30W lamp tube is 0.9 meters long, and is used for light boxes over 1. 1 meter. The thickness is generally 20-25 cm. When installing, install the lamp holder on both ends of the lamp holder with screws, and put the ballast beside it. It's best to stick it on with tape after trial burning. The power cord is connected according to the ballast circuit, and the wires are laid with thick wires along the wooden frame at 0.7MM and 0.8MM according to the schematic diagram of fluorescent lamp ballast. Board surface: mostly white background, divided into milky white and magnetic white plexiglass. Generally love to use magnetic whiteboard: first, white magnetic board, white surface; Second, scraps can be used to process small print, otherwise the milky white paste will not work, red on the red background, blue on the blue background and benzene board will not work, and glue marks can still be seen. Cut the board of the light box with a hook knife, and the length, width and size are 2-3 mm smaller than the wooden frame. Upper plate: when nailing small nails (15MM), drill a small hole with an electric drill first, otherwise the hard nail will crack and nail at the edge of 5MM, and nail three or four nails more than one meter long. Only four nails can be nailed to the 20MM wide side plate. Drill holes in the side to get the wires out. Aluminum strip: 20×20MM aluminum angle is used, and the length and width of plexiglass plate are better than 2 mm. The aluminum corner head is sawed at an angle of 45, and the screws are nailed on the side, with a thickness of 20MM and regular script on the front. Never see a nail. Paste organic characters: arrange the characters on the surface of the light box according to the design, check them lightly, straighten them, and then paste them with plexiglass glue. There are two ways to paste, one is to glue the organic glue on it, and the other is to suck the organic glue with a medical needle and gently inject the edge. The second one is better than the first one. Check whether there are any typos, missing words and typos, and check whether each word is glued tightly and whether there are any missing words. Cleaning: Use a small piece of clean cloth, dip it in some water, and then squeeze some toothpaste to wipe it evenly. After wiping evenly, dip a cloth in some water and wipe it on a large area. Water is not easy, but cloth is wet. Installation sequence: bracket design, blanking, welding and fixing. Key points of light box installation: check the orange structure of the wall before installation: check the strength and bearing capacity of the main structure before decoration, and deal with it in time if it does not meet the design requirements. To install pretreatment parts, store decoration should be consolidated, so the pretreatment parts should be installed in advance according to the design requirements. Basic requirements for light box installation: according to the position of accessories, the triangular bracket is generally welded with 2.5×2.5 angle steel. Horizontal light boxes are generally 20 cm away from the wall, and the arm length remains unchanged. The height of the boom is half the length of the boom, and diagonal braces account for 1/3 of it. If the light box 1.8× 1.2m is 20 cm away from the wall, two solid angle irons shall be welded. Fix the rear side of the big light box to prevent it from swinging. The height is at least 2/3 of the height of the light box. If the light box is erected, it will be 1.3×60×20, and the column can be raised not less than 2/3 of the light box. Installation of light box, 1.8× 1.2×20, must be welded into a half-frame light box. The upper and lower parts are firmly fixed. There is also a small light box, the size of which is less than 1.20×0.60×0.2, which is directly connected with the aluminum strip on the aluminum gusset plate. When installing the angle iron frame, drill four holes with the diameter of 10 on the bracket, and then put the bracket in the position where it needs to be installed. Determine the position of the hole and drill a hole with a diameter of 8 with an impact drill. Firmly fix the expansion screw, then align the bracket with the eyelet, screw on the nut and tighten it. Finally, fix the light box firmly with big wooden screws. Check whether it is safe again. Quality standard of operation technology: Layout: text should be clear, colors should be matched, make full use of color contrast, contrast should be large, and colors should be bright and eye-catching. The font size should be as large as possible, and the colors should be contrasted, so that the font will not appear crowded, and the board surface can be fully utilized.
