Ultra-thin light box is made as follows: 1. Outer frame making accessories: aluminum profile, corner coding tools: aluminum angle knife, 2.5mm hexagonal spoon. Production: refer to the specification table of ultra-thin energy-saving light box (see attachment), and open the bottom frame and the surface frame materials, both of which are the same length; Assemble the bottom frame with angle code. As shown in the figure: Secret Skill: The key to the quality of the outer frame is the adjustment of the 45-angle aluminum cutter. Our factory has a professional 45-angle cutting machine. There should be no burr in the incision as far as possible, and the length of parallel sides should be consistent, so that the angular assembly is beautiful. If there is no professional angle cutting machine, you can use two ordinary angle cutting machines to make a saw table with wood, install a steel ruler on it, adjust the angle of 45 degrees in the opposite direction and fix it. As shown in Figure 2, reflective film backing fittings: bottom frame; Wantong board (hollow PVC board, PVC corrugated board); Special reflective film tools: paper cutter and steel ruler: refer to the specification table of ultra-thin energy-saving light box, open Wantong board and reflective film, install reflective film on Wantong board, and then install it on the bottom frame. Secret skill: Wantong board is easy to use, and the special reflective film for light guide plate is different from the reflective glue used in advertising on the market. Li Long factory currently uses two kinds of reflective films. First, it is used for liquid crystal displays, made in Japan, with high cost; 2. Sino-foreign joint ventures are committed to indoor ultra-thin light box. . 3. Fixing fittings of light guide plate: bottom frame with reflective film; Across the light guide plate; Suitable gong wire tool: gong wire knife, drilling production: put the light guide plate flat on the bottom frame with reflective film and fix it with gong wire. Secret skill: Due to manual production, there will be some errors in the dimensions of the light guide plate and the bottom frame. Just put the light guide plate in the center of the bottom frame. 4. Installation of light source fittings: bottom frame with polishing plate; T4/T5 lamp or LED light source, electronic ballast, lamp socket, reflector, safety tube, 3-core flame retardant wire, wiring cap Tools: Gong wire trimmer, drill bit, ferrochrome production: first plan the circuit, weld the lamp socket and electronic ballast, and install them on the chassis respectively, and then install the lamp, reflector, fuse, grounding, power cord, etc. Check it, and then turn on the power. Secret skill: pay attention to leakage prevention. 5. Picture mounting accessories: pure organic board (1-2mm), aluminum frame, corner code, lamp piece (see attachment 1 for output dimensions). Tools: steel ruler, hook knife, paper cutter, hexagonal spoon, transparent glue with width of 1cm. Manufacturing: open the machine parts, install them on the face frame and fix them with angle codes. Install the lamp on the face frame with transparent adhesive. Tip: Be patient and don't wrinkle when installing the lamp. 6. Upper cover accessories: edge-sealing gong wire tool: gong wire cutter, drilling production: flat the upper cover on the bottom frame where the light guide plate is installed, and fix the edge-sealing gong wire on the side of the light box. Power on again. 7. Mounting and hanging accessories: rubber plugs, self-tapping or wire blasting tools: impact drills, gong wire cutters and level meters.
