3 Check the aluminum angle code positioning surface smoothness, if metal chips, sand and other foreign matter or impurities hard protective film wrinkled, surface profile with raised dots, etc. should be promptly cleaned up, we can not afford to deal with the profiles placed in substandard product area, and make a record and statistics;
4 Press the device operating requirements will be placed stacked aluminum angle cutting saws, if the positioning surface impurities or foreign matter should be promptly removed and cleaned;
5 Operation saws the pinch pressing cylinder sections to limit their freedom;
6 Operating dicing saw cutting angle code;
7 with compressed air gun purge clamping table and after cutting angle code, cleaning the chip;
8 scrub, aluminum Corner cleaning after processing, with a dry cloth coolant Corner on the other and dipped in alcohol wipe stains;
9 pairs cut quality inspection, qualified qualified products into the area, into the next process, the failure on the nonconforming area and make a record and statistics;
3, framed
3 framed work process
1 with a pneumatic gun has been loaded into the Corner border and short pit length of the border has been uniformly embossed into the amount of silica gel;
2 will be framed and placed on a battery pack mounted box machine, and fitted with long assembly around short aluminum frame; first placed adjacent to a short and a long aluminum side, and then the battery pack into the fixed aluminum frame groove inside, inside and parallel to the other two sides with an aluminum extrusion
3 framed machine will operate short border Corner pushed long the battery pack is embedded into the aluminum frame within the frame;
4 Remove framed good component is placed on the table, with a file to remove the burrs corner, if dislocation with a rubber hammer trimming. With a thickness gauge (feeler), steel ruler, right angle ruler, tape measure and other tools to detect the size of the joints, dislocation, numerical errors and frame diagonal 90 degree angle error and the like, the assembly qualified into the next process, unqualified then rework repair and make a record;
5 with a glue gun to uniformly fill the gap at the front of plastic;
6 Flip component, the component with the glue gun on the back of TPT and the gap at the aluminum frame were glue;
After the inspection is completed 7 glue seams with silicone border component should be uniform no visible gaps;
8 references cited in the backplane bus bar fight silica that leads on the rear seam is completely sealed;
9 by drawing to select the appropriate junction boxes and even full silicone coating in the junction box on the back of four weeks, according to the paper size junction box and gently pressed against the back of the assembly corresponding position, so that the bus bars through junction box hole with sticky back access;
10 Use a flat screwdriver to press the spring plate junction box connection point on the bus bar into the appropriate contacts, bus bars loosen slotted screwdriver is pressed in case of cross-wiring, must shrink sleeve on each bus bar tube, followed by hot air heating to tighten access to the appropriate contacts;
11 pairs of component again self-test, no abnormal components will be put on the four corners Corner, into the tray, into the next process.
4, Final Cleaning
1 After the module junction box installed on the components on the inspection procedure;
2 cleaning kit front glass surface, aluminum alloy frame front and side. First with a rag to remove excess gap at the front of the component silicone, if the component on the front glass are still remnants of silica gel or EVA, after carefully scraped off with a razor blade, cleaned with a rag dipped in alcohol, such as the case indelible stain, then rub In addition to the eraser. Flip component, using the same methods to clean the back of the backplane assembly, glue seam, border and junction boxes;
3 Check again whether the module surface completely clean, until the time when the cured silicone surface, the junction box cable bundled in the specified location;
Four pairs of component self-test to check whether the quality of the process to achieve the framing completed test.
