Abstract
The invention relates to a flexibility circuit board FPC finger folding bonding method and a special tool. In the invention, special tools for pre-folding, pre-pressing and rolling are adopted, a FPC to be folded is located on the special tool for pre-folding; a pressing plate is sleeved; the FPC to be folded is folded along the folding line; then the FPC is taken down and is located on the pre-pressing tool; the upper pressing plate of the pre-pressing tool is pressed; the FPC is folded and deepened along the folding line; the FPC is taken down from the special tool for pre-pressing; and a release paper of a pressure-sensitive adhesive is uncovered and then passes through a rolling wheel for rolling. Because the special tools for pre-folding, pre-pressing, and rolling are adopted, finger folding bonding is realized before the production formation and the whole flexibility circuit board is processed by the tools, so that the production efficiency is improved, the production operation method is stable and the quality of the product after being folded and bonded is ensured.
Description
Technical field
The present invention relates to folded, glued method and the used tool of a kind of flexible electric circuit board FPC, particularly a kind of flexible electric circuit board FPC finger folded, glued method and specific purpose tool.
Background technology
In flexible electric circuit board (the English FPC that the is called for short) industry, a lot of FPC need be after finger position pastes pressure sensitive adhesive, and it is bonding to point folding 180 degree backs again.Prior art is pure manual folded, glued; Monolithic FPC carries out the manual folded, glued of manual folded, glued or whole piece FPC, and to occur between two-layer after folding dislocation easily irregular; Defective productss such as off normal, few glue, glue be overlapping occur, production efficiency is low simultaneously, can't realize a large amount of productions.
Summary of the invention
The present invention provides kind of a flexible electric circuit board FPC finger folded, glued method and a specific purpose tool; Use pre-folds, precompressed, roll extrusion special tooling; Make the finger folded, glued be implemented in before the product shaping whole and carry out, improved production efficiency, guaranteed product quality behind the folding sticking platform with instrument.
For achieving the above object, the present invention provides a kind of flexible electric circuit board FPC finger folded, glued method, and concrete steps are following:
(1) will treat that folding FPC is positioned on the instrument of pre-folding by location hole, the cover top board.Be specially through the location hole on FPC and the pressing plate and with alignment pin on the base station FPC accurately located and fix FPC, base station and platen edge accurately overlap with the fold line on the FPC.Eliminated in the manual folding process and caused locating inaccurate few glue, the overlapping problem of glue of producing because of the FPC softness.
(2) press and pre-fold tool switch, briquetting is vertically descending, will wait that rolling over FPC folds along fold line.Briquetting is vertically descending, makes FPC along fold line while pressurized, has eliminated the off normal that manual folding FPC unbalance stress causes.
(3) take off FPC from the instrument of pre-folding, be positioned on the prepressing means.
(4) depress the prepressing means top board.FPC is further deepened folding along fold line, the angle that is folded is less than 90 degree, has deepened the effect that pre-folds, is convenient to roll extrusion.
(5) take off FPC from prepressing means, take the release liners of pressure sensitive adhesive off.
(6) with the folding limiting plate that is close to of FPC, cross roller and carry out roll extrusion.Spacing through limiting plate, indeformable behind the FPC.The FPC translational speed can reach 15 meters/minute, has improved production efficiency.
For achieving the above object, the present invention provides the specific purpose tool of flexible electric circuit board FPC finger folded, glued method, comprises the instrument of pre-folding, prepressing means, rolling tools.
The described instrument that pre-folds is made up of base station, pressing plate, briquetting, and pressing plate is positioned on the base station, and briquetting is positioned at pressing plate the place ahead and vertical with pressing plate.
Described prepressing means is made up of top board, lower platen, connecting axle, and top board, lower platen link to each other through connecting axle.
Described rolling tools are made up of table top, limiting plate, upper roller, bottom roller, and limiting plate vertically places on the table top, and upper roller is positioned on the table top, and bottom roller is positioned under the table top, and symmetrical with upper roller.Upper roller, bottom roller link to each other with external motor, and driven by motor upper roller, bottom roller rotation realize the roll extrusion to FPC.
Since adopted pre-fold, precompressed, roll extrusion specific purpose tool, make the finger folded, glued be implemented in before the product shaping whole and carry out with instrument, both improved production efficiency, also make the production operation method stable, guaranteed product quality after the folded, glued.

Embodiment
Combine Fig. 1, Fig. 2, Fig. 3 that the present invention is further described down.
The present invention provides a kind of flexible electric circuit board FPC finger folded, glued method, and concrete steps are following:
(1) will treat that folding FPC1 is positioned on the instrument of pre-folding by location hole, cover top board 2.Be specially through the location hole on FPC1 and the pressing plate 2 and with alignment pin on the base station 3 FPC1 accurately located and fix, base station 3 accurately overlaps with the fold line on the FPC1 with pressing plate 2 edges.
(2) press and pre-fold tool switch, briquetting 4 is vertically descending, will wait that rolling over FPC1 folds along fold line.
(3) take off FPC1 from the instrument of pre-folding, be positioned on the prepressing means.
(4) depress prepressing means top board 5, FPC1 is further deepened folding along fold line, and the angle that is folded is less than 90 degree.
(5) take off FPC1 from prepressing means, take the release liners of pressure sensitive adhesive off.
(6) with the folding limiting plate 6 that is close to of FPC1, cross roller 7,8 and carry out roll extrusion, the FPC translational speed can reach 15 meters/minute.
The described instrument that pre-folds is made up of base station 3, pressing plate 2, briquetting 4, and pressing plate 2 is positioned on the base station 3, and briquetting 4 is positioned at pressing plate 2 the place aheads and vertical with pressing plate 2.
