Below, briefly the operation principle of cutting off layered product film 1B in the apparatus for film adhesion of present embodiment is described.

At first, pull out rotating knife support component 16 here towards operator oneself with the self-locking of hook knob 109 location when removing the rotating knife that uses rotary cutter shown in Figure 1 with hand, enlarges the dead knife 15 of rotary cutter and the distance between the rotating knife 17.Then, manually the front of the direction of the supply of the layered product film 1B that will be separated by thin film component 3 is configured in main evacuated panel 6, front end is reeled with the front of film holding member 12 and dead knife 15, meanwhile, this thin film adsorbs is remained on main evacuated panel 6 and the front end coiling usefulness film holding member 12.At this moment, disposing this layered product film 1B makes the position of the outstanding some length of its front end reel with base plate conveying channel one side position of film holding member 12 at front end.Then, the position when aforementioned rotating knife support component 16 is set in the rotating knife that uses rotary cutter, and pin aforementioned location hook knob 109.

Secondly, as shown in Figure 8, set aforementioned rotating knife support component 16, allow the angle adjustment of rotary cutter set the dead knife 15 and the rotating knife 17 of rotary cutter for right angle towards the action of arrow aspect and with respect to the direction of the supply of layered product film 1B with cylinder 106A and 106B.

Then, for carrying out the preparation that first film is pasted, the operating switch (figure part omitted) of layered product film 1B front film is cut off in operation, make rotary cutter work, cut the fore-end of outstanding some this layered product film 1B of base plate conveying channel one side that is positioned at front end coiling usefulness film holding member 12, abandon.As a result, the front of this layered product film 1B is vertically cut off with respect to the direction of the supply of film.

Then, as shown in Figure 9, make rotary cutting-tool angle adjustment with cylinder 106A and 106B towards direction of arrow action and the inclination angle of setting the dead knife 15 and the rotating knife 17 of rotary cutter for regulation with respect to the direction of the supply of layered product film 1B.

Then, operate 1 later continuous film cut-out step switch continuous film is cut off, like this, the cut-out of relevant layered product film 1B can be by rotation rotating knife 17, by itself and dead knife 15 instantaneous shearing lamination body thin film 1B, cut off layered product film 1B rapidly and accurately.

The layered product film 1B front end of (first film is pasted and prepared) positions when cutting off before to aforementioned beginning, can easily rotating knife support component 16 be pulled out to the operator front with knob 109 location when using the rotating knife of rotary cutter, pull out the back as long as push back simply.That is to say, adjust with screw 111 and location usefulness knob 109 when using the rotating knife of rotary cutter, can be set in the use location of rotating knife 17 at an easy rate by brake 110, location.

Then, just use the automatic stickup operation (heat lamination) of aforementioned apparatus for film adhesion, an embodiment of method for adhesion of film of the present invention is described with reference to Figure 10～19 (the major part structure diagram of representing each paste operation operation).

At first, must trim with manual front end continuous laminating body thin film 1B, as shown in figure 10, extract location knob 109, draw rotating knife support component slide unit 105 along the direction of arrow, and by pulling out rotating knife support component 16 to the operator front, just can guarantee layered product film 1B by the time enough spaces of needing, thereby layered product film 1B is passed through.

Then, as shown in figure 11, after layered product film 1B passes through, rotating knife support component 16 is pushed the position that cuts off layered product film 1B, with knob 109 rotating knife support component slide unit 105 is pinned reliably with the location.After rotating knife 17 configures, operate first film and cut off operating switch, make rotary cutter work, cut off the redundance of this layered product 1B and front end is trimmed.The front of the continuous laminating body thin film 1B of this moment is vertically cut off with respect to the direction of the supply of film.At this moment, the dead knife support component 14 and the rotating knife support component 16 of rotary cutter still remain on horizontal level, and this state is shown in Figure 12.

The front end that carries out with manual operation of being through with trims the front of the direction of the supply of the layered product film 1B of operation, as shown in figure 13, is reeled with thin film component 12 absorption, is kept by front end, and its front-end configuration is in the front of rotary cutter dead knife 15.When the film of selecting automatic operating mode is pasted operation, when beginning to paste work, the dead knife support component 14 of rotary cutter and rotating knife support component 16 just by rotary cutting-tool angle adjustment with the driving of cylinder 106A and 106B towards with the perpendicular direction inclination of membrane supplying direction.

Secondly, rely on the base plate conveyer, to transport to the assigned position of base plate conveying channel by the printed circuit board wiring base plate 22 that driven roller 23A and driven voller 23B transport along base plate conveying channel I-I, detect this point by the base plate front position detecting sensor that is arranged on the base plate conveyer, when signal one is detected, just controlling aforementioned dead knife shown in Figure 1 moves forward and backward with cylinder 103A and 103B (not shown in figure 1), front end is reeled to be moved towards the incline direction shown in Figure 14 (direction of arrow B) with film holding member 12 and dead knife 15, the front of the direction of the supply of layered product film 1B is moved towards the position of the supply passageway that deviates from layered product 1B, and make its absorption, remain on the leading section 6D of main evacuated panel 6.At this moment, spray compressed air to the direction of arrow A, make on its leading section 6D that more easily adsorbs, remains on main evacuated panel 6, simultaneously, prevent from fold to occur on the layered product film 1B through air injection tube 19 and 20.

When on transporting each base plate 22 that comes one by one, carrying out the film stickup automatically and continuously, can adsorb, remain on the leading section 6D of main evacuated panel 6 by the front of the layered product film 1B direction of the supply that rotary cutter cut off.

Then, utilize the base plate conveyer will stop at the film paste position along the leading section that base plate conveying channel I-I transports the carriage direction of the printed circuit board wiring base plate 22 that comes by driven roller 15A and driven voller 23B.This stops to move is according to being arranged on the detection signal that sensor on the base plate conveyer detects the leading section of printed circuit board wiring base plate 22, and the driven roller 23A that makes base plate transport machinery stops to realize.

Then, as shown in figure 15, make main evacuated panel 6 and front end 6D thereof near stopping at the leading section surface (film stickup face) of the carriage direction (arrow C direction) of the printed circuit board wiring base plate 22 of film paste position, the front of the direction of the supply of layered product 1B is offered the film paste position.

Then, as shown in figure 16, make absorption, keeping the main evacuated panel 6 of layered product film 1B and leading section 6D thereof to move to the film paste position, and with on the film stickup face of leading section 6D by the carriage direction leading section that is attached to printed circuit board wiring base plate 22, the supply side front end with layered product film 1B is crimped on the base plate 22 at last.

Then, as shown in figure 17, remove the absorption hold mode of lamination body thin film 1B, make main evacuated panel 6 and leading section 6D thereof leave the film paste position.After main evacuated panel 6 leaves and arrives as shown in figure 17 position, continue to make the film holding member support component 8 that is integral setting with main evacuated panel 6, as shown in Figure 2, move along the direction that deviates from base plate conveying channel I-I, main evacuated panel 6 and front end are reeled use film holding member 12 printed wiring base plate 22 further away from each other,, dead knife support component 14 still remains on original position.

Highest distance position is meant that deviating from of the promptly main evacuated panel 6 in position shown in Figure 180 carve in the release, at this moment, dead knife support component 14 and front end is reeled with film holding member 12 from the rear near layered product film 1B.According to this action, thermo-compressed roller 21 begins to move to the film paste position from retreating position, promptly begins to move towards arrow D direction.

When thermo-compressed roller 21 moves to the film paste position, just with the direction of the supply of appropriate pressing force and layered product film 1B foremost side join.And the rotation once again of the rotation of dependence thermo-compressed roller 21 and the driven roller 23A of base plate conveyer is transported printed circuit board wiring base plate 22 towards the arrow E direction, and begins base plate 22 is carried out the attached stickup of pressure of layered product film 1B.

As shown in figure 18, provide aforementioned laminates film 1B what rely on aforementioned hot crimping roller 21 rotational automaticly, simultaneously, from the carriage direction leading section of printed circuit board wiring base plate 22 backward end distance in accordance with regulations layered product film 1B is sticked on the film stickup face of printed circuit board wiring base plate 22.

When sticking on layered product film 1B on the printed circuit board wiring base plate 22, dependence thermo-compressed roller 21 in the process of base plate carriage direction mobile printing wiring base plate 22, rely on this shift action that layered product film 1B is pulled out from donor rollers 2.

When the rearward end of layered product film 1B was positioned at the assigned position of base plate conveyer, this state can be detected by the sensor that is arranged on the conveying channel, according to this detection signal:

(a) main evacuated panel 6 and front end are reeled and are begun to transport the motion of circuit I-I direction and make its stickup speed with layered product film 1B identical towards base plate by motor-driven with film holding member 12, and adsorb, maintain layered product film 1B.At this moment, operating path one side towards layered product film 1B begins rotation to the rotating knife 17 of rotary cutter from initial position.Main evacuated panel 6 and front end are reeled with film holding member 12 close dead knife support component 14 under the state of absorption, maintenance layered product film 1B, reel when reaching the extremely narrow interval of regulation at front end, just finish the cut-out operation of lamination body thin film 1B with the interval between film holding member 12 and the dead knife support component 14.

Setting to the film length of the boundary point of body part that is positioned at membrane supplying parts 6 and film front end wrapping range, makes its length with aforementioned film front end wrapping range consistent from the blade position of the dead knife 15 in the moment of the cut-out that finishes aforementioned laminates film 1B.

In addition, setting begins to the length of the layered product film 1B of the rear end of the layered product film 1B that cuts with rotary cutter its length with the film stickup residual fraction that is positioned at printed circuit board wiring base plate 22 surfaces to be equated in fact from the film press points of thermo-compressed roller 21.

The rear end side of the direction of the supply of aforementioned continuous layered product film 1B as shown in figure 19 should be corresponding with the length of the carriage direction of aforementioned printed circuit board wiring base plate 22.After cutting off release, main evacuated panel 6 and front end are reeled and are made holding member 12 static under the state that adsorbs, maintains layered product film 1B with film.

Then, the rear end side of the direction of the supply of the layered product film 1B of aforementioned cut-out is sticked on the film stickup face of rearward end of carriage direction of printed circuit board wiring base plate 22 with aforementioned hot crimping roller 21.That is to say that the front of the direction of the supply of layered product film 1B is also pasted by hot pressing the end from the carriage direction leading section of printed circuit board wiring base plate 22 backward successively by the rotation of thermo-compressed roller 21 and transporting of printed circuit board wiring base plate 22.The rear end side of the direction of the supply of the layered product film 1B after the cut-out is subjected to penetrating the injection of pipe 20 towards the air of the direction of arrow shown in Figure 19 by air, and rely on the absorption action of vacuum bar 25, the Surface Edge of limit friction vacuum bar 25 is passed through, therefore the layered product film 1B before will pasting to hot pressing brings the tension force of appropriateness, makes the layered product film 1B of thermo-compressed on printed circuit board wiring base plate 22 can not produce fold etc.

Then, after the rear end side thermocompression bonded of the direction of the supply after layered product film 1B is cut off was attached on the film stickup face of rearward end of printed circuit board wiring base plate 22 carriage directions, the heat lamination operation finished.Before end is pasted in hot pressing, when stage that the remaining lengths of the layered product film 1B that forms direction of the supply rear end side has shortened, aforementioned vacuum bar 25 is done turning motion around thermo-compressed roller 21, with near printed circuit board wiring base plate 22, and adsorbed action before heat lamination finishes, and the tension force of applying appropriateness for layered product film 1B, prevent the generation of fold etc.The printed circuit board wiring base plate 22 that finishes is given hypomere by the base plate conveyer exposure device is pasted in aforementioned hot pressing.

Thereafter, described vacuum bar 25 is towards deviating from direction reverse rotation around thermo-compressed roller 21 that base plate transports circuit I-I, and turns back to the origin-location.At this moment, thermo-compressed roller 21 also to carriage direction one side shifting of printed circuit board wiring base plate 22, makes thermo-compressed roller up and down 21 separately towards deviating from base plate conveying channel I-I direction, simultaneously, backs out from the film paste position.

In sum, by the present invention can make supply with film both do not had loose, again can be with respect to the membrane supplying direction fast, vertically cut off, and the film that cuts off is sticked on the base plate with the film of wide cut.

In addition, only make the rotating knife rotation once, just can make this flying knife and dead knife shear continuous films, so the film of wide cut quickly and reliably can be cut off and it is sticked on the base plate.

In addition, owing to can before the work beginning, at an easy rate continuous film be inserted in the device, improved the operating characteristics of device.
