The utility model discloses when using, divide into following three main step:
the first step is as follows: place earlier cushion block 2, place cushion block 2 earlier, in cushion block 2 puts into locating frame 10, let locating frame 10 block cushion block 2 and do not drop, hold locating frame 10 and put into standing groove 19 simultaneously, it is accurate to counterpoint, easy operation. If there is not locating frame 10, standing groove 19's size should set up with cushion 2 relatively, because of cushion 2 is flexible, it is difficult for putting into to do the standing groove of dark a bit, and because of powerful pressure cushion 2 down when the laminating, cushion 2 has the rebound effect after the laminating is accomplished, cushion 2 easily pops out standing groove 19, the laminating needs the relocation once more, if standing groove 19 does shallowly, the total height of mould uprises, highly also corresponding the uprising in the laminating storehouse, the cost is also corresponding higher.
The second step is that: tear the protection film of dry glue, dry glue is counterpointed with the apron, let dry glue and apron central point put and glue a bit, do the location usefulness, place rubberizing cushion 2 on the base 1 (put positioning die after putting the cushion earlier), put into apron positioning die 3 to the apron again, the second cushion has viscidity (there is viscidity apron just not drop down), after the location, put apron positioning die 3 at the thimble axle 23 top of base 1, second locating hole 8 corresponds with thimble 4 and places, the apron is down. At the moment, the whole set of mould is put into a laminating machine for laminating, and dry glue is laminated on a cover plate.
The third step: the liquid crystal screen is placed into the liquid crystal screen positioning groove 5 of the cover plate positioning die 3, the first rubber pad 9 is sticky, after positioning is completed, the positioning die is placed on the positioning ejector pin of the base, the rubber pad block 2 is placed on the base 1, the first positioning hole 7 is placed corresponding to the ejector pin 4, and the liquid crystal screen faces downwards. At this moment, the positioning die is pressed downwards by manpower, and the liquid crystal screen is stuck on the rubber cushion block 2 of the base 1 to play a role in positioning. Taking out the cover plate positioning die 3, adopting the positioning groove on the other side, putting the cover plate into the positioning groove, tearing off the dry glue protective film attached on the cover plate after positioning, and putting the cover plate positioning die 3 on the thimble shaft 23 of the thimble 4 on the base 1, wherein the cover plate faces downwards. At the moment, the whole set of mold is placed into a laminating machine, the liquid crystal display and the cover plate are laminated, and the liquid crystal display and the cover plate are integrated after lamination is completed, so that lamination is completed.
The utility model discloses a cushion of turriform design can make the cushion bottom and the middle level size of each model unified, and the upper strata size sets up with corresponding different model display screen sizes relatively, and the central point on upper strata puts and can places the position according to the apron in the apron mould and set up relatively, because of the bottom is unified size, the middle level also is unified size, need not the design of a model locating frame, realizes that a frame is general. The utility model discloses a high height of the laminating storehouse of rigging machine can be reduced to the height that the cushion and the locating frame setting of base top are in the standing groove (the standing groove is deepened more, the total height is lower) to the cost has been saved greatly to the height in the laminating storehouse of messenger's rigging machine. When placing the cushion block, the cushion block is put into the locating frame earlier, lets the locating frame block the cushion block and does not drop, puts into the standing groove simultaneously by hand the locating frame, and it is accurate to counterpoint, easy operation. If there is not the locating frame, the size and the cushion of standing groove set up relatively, have elasticity because of the cushion, do the standing groove of dark a bit and be difficult for putting into, and because of powerful the cushion that pushes down during the laminating, the cushion has the bounce-back effect after the laminating is accomplished, and the cushion easily pops out the standing groove, and the laminating needs the relocation once more, and the standing groove is done shallowly, and the total height of mould uprises, and highly also corresponding uprising in the laminating storehouse, and the cost is also corresponding higher.
