STICKIN(~ APPARAlllS
BACKGROUND OF THE INVENTION
The present invention relates to a film sticking art, particularly to a film sticking art in which a film having a length corresponding to that of a base plate or panel is stuck to the film sticking surface of the plate.
A process in which a printed circuit board for an electronic machine such as a computer is manufactured includes a procedure in which a stratified body is stuck to the surface of a base plate or panel for the board. The stratified body consists of a light-transmissible resin film and a photosensitive resin layer which is a resist layer. The photosensitive resin layer is directly stuck to the surface of the base plate. The light-transmissible resin film is provided on the photosensitive resin layer to protect it. The sticking of the stratified body to the base plate is performed by a sticking apparatus as disclosed in the Japanese Patent ~pplication (OPI) No. 117487/88 made by the present applicant.
The procedure in which the stratified film is stuck to the base plate by the apparatus is described from now on. The base plate is first conveyed by a base plate conveyance mechanism so that the leading edge of the base plate with regard to the direction of the conveyance thereof is stopped in the position of the sticking of the film. The light-transmissible resin film side of the leading edge portion of the long continuous 2~2~8 stratified body fed from a film supply roller is then sucked by a main vacuum suction plate which is a film feed member. A
film tentative sticking member is provided at the leading end of the main vacuum suction plate, which is located nearer the film sticking position than the other end of the suction plate, so that the leading edge portion of khe stratified body is sucked on the film tentative sticking member. The film tentative sticking member has suction holes communicating with a vacuum suction unit for sucking the stratified body, and has a heater provided in the member itself so as to tentatively stick the leading edge of the stratified body to the base plate. The main vacuum suction plate and the film tentative sticking member are moved to the vicinity of the film sticking position, namely, to the vicinity of the surface of the lading edge portion of the base plate. The leading edge of the stratified body is then put into contact with the film sticking surface of the leading edge portion of the base plate, and tentatively stuck thereto under heat and pressure by the tentative sticking member. The main vacuum suction plate and the tentative sticking member are thereafter put out of sucking action and moved away from the film sticking position. At that time, since the leading edge of the stratified body is already tentatively stuck to the surface of the base plate, the leading edge does not deviate from the films ticking position. A head and pressure sticking roller is then moved to the vicinity of the film sticking position while being rotated, so that the 2 ~ 8 tentatively stuck portion of the stratified body is pressed by the roller. Because of the rotation of the roller, the stratified body is gradually stuck, under heat and pressure, to the surface of the base plate and the base plate is conveyed forth further. The stratified body is automatically fed to the films sticking position because of the rotation of the heat and pressure sticking roller and the conveyance of the base plate.
During the heat and pressure sticking of the stratified body to the surface of the base plate by the roller, the trailing edge of the base plate is detected so that a detection signal is generated. The continuous stratified body is cut off on the basis of the detection signal so that the cut-off body has the trailing edge thereof and the cut-off length of the body corresponds to that of the base plate. For the cutoff of the stratified body, a cutter is moved in a direction across that of the feed of the stratified body as an auxiliary vacuum suction plate provided at a stratified body feed passage holds, by suction, the stratified body at its portion to be cut off.
The cutter is a disk-like cutter. The cut-off trailing edge portion of the stratified body is guided to the trailing edge portion of the base plate as a vacuum suction bar which is a film trailing edge suction member holds the trailing edge portion of the stratified body by suction so that appropriate tension is applied to the body. The trailing edge portion of the stratified body is stuck, under heat and pressure, to the surface of that of the base plate by the heat and pressure 2~2~9~
sticking roller. The base plate thus stuck with the stratified body by the sticking apparatus is conveyed to an exposure apparatus installed next to the sticking apparatus. Such a kind of a film sticking art in which a stratified body is tentatively stuck at a portion thereof to a base plate and thereafter stuck thereto under heat and pressure was also disclosed in the West German Patent DE 3334009 C2, the Japanese Patent Application No. 59169/87 and so forth.
The above-mentioned procedure in which the stratified body is stuck to the base plate includes a step in which the stratified body is cut off by the cutter during the sticking of the stratified body to the base plate by the heat and pressure sticking roller so that the cut-off stratified body has the trailing edge thereof. At the time of the cutoff, a chip is made from the stratified body and flies away to contaminate the ambience in such a manner as to cling to the surface of the base plate, that of the stratified body or the like. The portion of the base plate or the stratified body, to which the chip is clinging, is likely to become a defective portion to increase the number of defective base plates to lower the yield in the sticking. This is a problem.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide film sticking art in which the contamination by a chip made from a film at the time of cutting thereof is reduced.
2 ~ 2 ~
It is another object of the present invention to provide an art in which the yield in the sticking of a film is enhanced.
The above-mentioned and other objects and novel features of the present invention will be apparent from the description herein and the drawings attached hereto.
In order to attain the above-noted and other objects of the invention, according to the invention, there is provided a sticking apparatus for sticking a continuous film to a film sticking surface of a base plate from a leading edge thereof toward a trailing edge thereof, comprising: a cutter means for cutting off said film during said sticking of said film so that the cut-off film has a length corresponding to that of said base plate; a holding member provided at a feed passage for said film near a position of said cutoff for holding said film near its portion to be cut off, said cutter means being provided in such a position that said cutter means faces said holding member across said film held by said holding member;
and a chip suction means provided near said position of said cutoff for sucking a chip made from said film at the time of said cutoff of said film.
Since the chip made from the film during the sticking thereof to the base plate is removed by the chip suction means of the sticking apparatus provided in accordance with the present invention, it is less likely that such a chip is left as a contaminant on the surface of the base plate, on that of the film, between the base plate and the film or/and in the 2Q~98 body of the apparatus. This resuits in enhancing the yield in the sticking of the film to the base plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
An embodiment of the present invention is hereafter described in detail with reference to the accompanying drawings.
In a sticking apparatus according to the invention, three-layer stratified films 1 each consisting of the light-transmissible resin film, the photosensitive resin layer and another light-transmissible resin film are continuously wound on supply rollers 2 is advance. The stratified film 1 from 202~198 each of the supply rollers 2 in advance. The stratified film 1 from each of the supply rollers 2 is separated, by a film separation member 3, into the light-transmissible resin film lA
as a protective film and the stratified film lB consisting of the other light-transmissible resin film and the photosensitive xesin layer exposed on its side to be stuck to the base plate.
The effective length of the film separation member 3 is not less than the maximum width of films to be stuck by the sticking apparatus. The separation edge portion of the separation member 3 is shaped as a wedge. For that reason, the resistance to the separation of the light-transmissible resin film lA and the stratified film lB by the separation member 3 is so low and the fluctuation of the point of the separation is so small that the films lA and lB can be smoothly separated from each other by the member.
The light-transmissible resin film lA separated from the stratified film lB is wound on a winding roller 4. A pair of such winding rollers 4 are provided over and under the base plate conveyance passage I-I as well as the supply rollers 2.
The leading edge of the separated stratified film lB is fed to the main vacuum suction plate 6, which is a film feed member, along a tension roller 5, as shown in Fig. 2.
As shown in Fig. 6, the main vacuum suction plate 6 is made of a magnetic substance such as iron, alumina or the like. The body of the plate 6 has suction grooves 6G and suction holes 6H, which communicate with a vacuum suction system for sucking ~2~
the stratified film ls on the plate. The leading end portion 6D of the plate 6 also has such suction grooves and such suction holes. The plate 6 is vertically moved toward and away from the position Gf the sticking of the film lB, as shown in Fig. 2. The plate 6 is slidable fitted on guide rails 7 attached to a support plate 8 for the plate 6, as shown in Fig.
6. The support plate 8 is coupled with a rac~ and a pinion 10 to a mounting frame 601 attached to the casing of the sticking apparatus, so that the support plate can be vertically moved.
The pinion 10 is engaged with a rack 602 provided on a vertically moving rod 603 coupled to a driving motor 11. The rack 602 is vertically moved by a push roller 604 having a rotary shaft 604A attached to the mounting frame 601. The support plate 8 is coupled to the film holding member 12 which is for winding the leading edge portion of the stratified film lB to cut it off and is slidable fitted on horizontal guide rails 605.
The film holding member 12 has suction grooves 12G and suction holes 12H, which communicate with the vacuum suction system for sucking the stratified film lB, as shown in Fig. 6.
The longitudinal edge area 12R of the film holding member 12, which is located nearer the fixed cutting member 15 of the rotary cutter than the other longitudinal edge area of the holding member 12, does not have any of the suction grooves 12G
but some of the suction holes 12H, so that the stratified film lB can be securely held by the holding member 12. If the area 2a2g~ ~
12R had such a suction groove, it would be likely that the continuous stratified film lB fed from the film supply roller 2, cut off by the rotary cutter and held by the film holding member 12 did curl at the leading edge of the film due to the suction groove and the leading edge did project outward to lower the security of the holding of the film by the film holding member 12. The holding member 12 is provided with coupling notched members 606 in which coupling rods 13 are fitted. The coupling rods 13 are attached to a support member 14 for the fixed cutting member 15 of the rotary cutter, as shown in Figs. 1 and 6. The fixed cutting member 15 and 15A of the rotary cutter is supported by the support member 14 attached to slide members 101 which are for sliding the support member 14 and are slidable fitted to rotary cutter support members 102 so that the slide members 101 are moved backward and forward by pneumatic cylinders 103A and 103B. A member 104 for adjusting the position of the fixed cutting member 15 is provided in a prescribed position on the piston rod of the pneumatic cylinder 103A. Slide member 105 for a support member 16 for the rotary cutting member 17 of the rotary cutter are slidable fitted to the rotary cutter support member 102 so that the slide members are manually moved backward and forward.
A rotary cutter angle adjuster 106, which is a pneumatic cylinder secured to the mounting frame 100 of the casing of the sticking apparatus, is provided at one end of each rotary cutter support member 102. A rotary cutter horizontal or ~ ~ 2 s~
oblique position angle setting member 107 is provided on each rotary cutter support member 102 near the rotary cutter angle adjuster 106 and secured to the mounting frame 100. A rotary cutter an~le adjustment pin 107A is provided to adjust the angle of the rotary cutter to put it in a horizontal or oblique position.
The support member 16 for the rotary cutting member 17 of the rotary cutter is attached to the slide members 105. The rotary cutting member 17 is rotatably supported by the support member 16 and has a cutting portion 17A obliquely extending at a prescribed angle. Brake xings 17B for the fixed cutting member 15 of the cutter are provided on the rotary cutting member 17 at both the ends thereof.
As shown in Fig. 3, a servomotor 108 for rotating the rotary cutting member 17 by a prescribed angle is provided at one end of the support member 16 for the rotary cutting member.
A gear 108A is mounted on the rotary shaft of the servomotor 108 and engaged with a gear 108B mounted on the rotary shaft of the rotary cutting member 17. Positioning engagement knobs 109 for the rotary cutter are provided at both the ends of the support member 16 so that the slide members 105 for the sl1pport member 16 for the rotary cutting member 17 are positioned and locked by the knobs when the rotary cutter is put in and out of use. When the rotary cutter is put out of use as in laying the stratified film lB through between the fixed and rotary cutting members 15 and 17 of the cutter for the first time, the positioning engagement knobs 109 are manually pulled out and the slide members 105 for the support member 16 for the rotary cutting member are then moved forward so that the rotary cutting member is much opened from the fixed cutting member.
The knobs 109 are then pushed into fitting holes at the sides of the knobs so that the slide members 105 are positioned and locked.
Air blowoff pipes 19 and 20 for blowing air to the stratified film lB are provided over and under the support member 16 for the rotary cutting member 17. The side of each of the pipes 19 and 20, which faces the stratified film lB, has a large number of air blow-off holes at the interval of about 20 mm in the longitudinal direction of the pipe. The pipes 19 and 20 are secured to attaching members on the support member 1~ for the rotar~ cutting member 17 so the pipes extend rectangularly across the direction of the feed of the stratified film lB when the pneumatic cylinders 106A and 106~
constituting the rotary cutter angle adjusters are driven in directions as shown by arrows in Fig. 11, to set the fixed cutting member 15 at a prescribed oblique angle to the direction of the feed of the stratified film. For that reason, the air is blown to the film lB uniformly with regard to the width of the film.
Stoppers 110 for positioning the slide members 105 at the time of the use of the rotary cutting member 17 are provided on the support member 102 for the rotary cutter. Positioning 2 ~
screws 111, which are stopped by the stoppers 110, are provided on the slide members 105 at both the ends thereof.
Fig. 7 shows the positional relation between the fixed and rotary cutting members 15 and 17 of the rotary cutter. The fixed cutting member 15 is always urged by a spring not shown in the drawings, so that the cutting portion 15A of ~he member is oriented to the base plate conveyance passage I-I.
As shown in Figs. 1, 3 and 8, a chip box 201, into which chips made from the continuous stratified film ls at the time of the cutoff thereof are collected by suction, is provided near the position of the cutoff. The chip box 201 has a suction slot 201A near the cutoff position. A suction duct 202 is connected to the chip box 201 at the prescribed portion thereof and communicates with a suction unit (not shown). The width of the suction slot 201A is S mm to 6 mm, for example.
A filter made of synthetic fibers to catch the chips of the stratified film lB is provided in the suction duct 202. The chip box 201 is supported by a rest 203 secured to the support member 16 for the rotary cutting member 17.
Fig. 9 shows such a chip box 201 for lower stratified film lB under the base plate conveyance passage I-I.
Fig. 2 shows heat and pressure sticking rollers 21, the base plate 22, driving rollers 23A, driven rollers 23B, base plate holding units 24 and vacuum suction bars 25. Each of the base plate holding units 24 includes a base plate holding roller 24A and a pneumatic cylinder 24B for moving the roller 2~2~ 98 up and down. When it is detected by a base plate leading edge position sensor, which is provided near the base plate conveyance passage but not shown in the drawings, that the base plate 22 is conveyed to a position in which the stratified film lB is tentatively stuck to the base plate, a detection signal is sent out from the sensor so that the rotation of the driving rollers 23A is stopped on the basis of the detection signal.
At the same time, the base plate holding rollers 24A are stopped. Immediately after the leading edge of the base plate 22 has passed under the base plate holding roller 24A, the pneumatic cylinder 24B is put into action on the basis of a detection signal so that the base plate 22 is held by the holding unit 24. The movement of the base plate 22 is thus stopped by the base plate holding roller 24A surely. For that reason, even if the leading end portion 6D of the main vacuum suction plate is not moved, thus maXing it possible to tentatively stick the stratified film lB to the base plate securely. Holding the base plate by the roller 24A is performed until the heat and pressure sticking roller 21 comes into contact with the base plate. The pneumatic cylinder 24B
is put out of action synchronously with the sticking roller's coming into contact with the base plate 22.
The cutoff of the continuous stratified film lB in the sticking apparatus is briefly described from now on. The positioning engagement knobs lO9 are manually unlocked. The support member 16 for the rotary cutting member 17 of the - ~2~
rotary cutter is then pulled out forward so that the rotary cutting member is much opened from the fixed cutting member 15 of the rotary cutter. After that, the leading edge of the stratified film lB separated from the light-transmissible resin film lA by the film separation member 3 is manually put in front of the main vacuum suction plate 6, the film holding member 12 and the fixed cutting member 15, and the film is held on the main vacuum suction plate 6 and the film holding member 12 by suction. At that time, the leading edge of the film lB
is located nearer the base plate conveyance passage I-I than the film holding member 12. If the width of the film ls is smaller than the length of the suction groove 6G of the main vacuum suction plate 6 and that of the suction groove 12G of the film holding member 12, the suction grooves would be partly exposed at the side edges of the film held on the suction plate and the holding member by suction, to let external air flow into the suction grooves to reduce the sucking forces of them on the film. To prevent the reduction in the sucking forces, the portions of the suction grooves 6G and 12G, which are exposed at the side edges of the film lB, may be sealed with adhesive tapes. If the s~lction plate 6 and the holding member 12 are made of a magnetic substance such as iron, the exposed portions of the suction grooves 6G and 12G may be sealed with magnetic tapes. If some suction holes of the plate 6 and the member 12 are exposed for the above-mentioned reason, the suction holes may be sealed with adhesive tapes or magnetic 2 Q ~
tapes. After the support member 16 is set in a position for the use of the rotary cutting member 17 o the rotary cutter, the positioning engagement knobs 109 are locked again. The support member 16 for the rotary cutting member 17 is then manipulated by driving the pneumatic cylinders 106A and 106B in directions as shown by arrows in Fig. 10, so that the fixed and the rotary cutting members 15 and 17 are set to extend rectangularly across the direction of the feed of the stratified film lB. A switch, which is for cutting off the stratified film lB at is leading edge portion extending slightly nearer the base plate conveyance passage I-I than the film holding member 12 but is not shown in the drawings, is operated to put the rotary cutter into action to cut off the film at the leading edge portion thereof in preparation of sticking the film to the base plate for the first time. At that time, the film lB is cut off at the leading edge portion thereof rectangularly to the direction of the feed of the film.
The pneumatic cylinders 106A and 106B are then driven in the directions as shown by the arrows in Fig. 11, so that the fixed and the rotary cutting members 15 and 17 extend at the prescribed oblique angle to the direction of the feed of the stratified film lB. As a result, the air is blown to the film lB uniformly with regard to the width thereof. A switch for continually cutting off the film lB to perform the first and other following sticking thereof is thereafter operated to continually cut off the film. For the cutoff of the film lB by 2 ~ 9 8 the rotary cutter, the rotary cutting member 17 is rotated so that the fllm is instantaneously nipped by the fixed and the rotary cutting members 15 and 17. The stratified film lB can thus be securely and quickly cut off.
For the cutoff of the leading edge portion of the stratified film in preparation of sticking the film to the base plate for the first time, the support member 15 for the rotary cutting memher 17 of the rotary cutter can be easily pulled out forward by manipulating the positioning engagement knobs 109 and thereafter simply pushed bacXward. The position of the rotary cutting member 17 in use can thus be easily set by using the positioning stoppers 110, the positioning screws 111 and the positioning engagement knobs 109.
Automatically sticking each of the upper and the lower stratified films lB, under heat and pressure, to the base plate 22 by the sticking apparatus is hereafter described with reference to Figs. 12, 13,14, 15, 16, 17, 18, 19, 20 and 21 which are schematic views of a major part of the apparatus in respective steps of the sticking. To manually cut off the continuous stratified film lB at the leading edge portion thereof to true up the leading edge of film, the positioning engagement knobs 109 are pulled out, and the slide members 105 for the support member 16 for the rotary cutting member 17 are pulled in a direction shown by an arrow in Fig. 12, to pull out the support member forward to make a wide space to lay the film through. After the film lB is laid through the wide space, the 2~2~1~8 support member 16 is pushed in to the position in which the stratified film lB is cut off and slide members 105 for the support member are then securely locked by the positioning engagement knobs 109, as shown in Fig. 13. After the rotary cutting member 17 is thus set, the switch for cutting off the film lB for the first time is operated to put the rotary cutter into action to cut off the unnecessary leading edge portion of the film lB rectangularly to the direction of the feed thereof to true up the leading edge of the film. At that time, the support member 14 for the fixed cutting member 15 of the rotary cutter and the support member 16 for the rotary cutting member thereof remain in horizontal positions as shown in Fig. 14.
The trued-up leading edge of the stratified film lB whose leading edge portion is already cut off is held on the film holding member 12 by suction and located in front of the fixed cutting member, as shown in Fig. 15. When automatic sticking the film lB to the base plate 22 is started by selection, the support member 14 for the fixed cutting member 15 and the support member 16 for the rotary cutting member 17 are obliquely shifted by the pneumatic cylinders 106A and 106B so that the support embers extend rectangularly across the direction of the feed of the film.
When it is thereafter detected by the base plate leading edge position sensor provided at a base plate conveyor that the base plate 22 is conveyed to a prescribed position in the base plate conveyance passage by the driving rollers 23A and the driven rollers 23B, the holding mèmber 12 and the fixe cutting member 15 are moved by the pneumatic cylinders 103A and 103B in a direction shown by an arrow B in Fig. 16, so that the holding member and the fixed cutting member extend obliquely across the direction of the feed of the film lB. As a result, the leading edge portion of the film lB is moved so that the portion is held on the leading end portion 6D of the main vacuum suction plate 6 by suction. At that time, the compressed air is blown from the air blowoff pipes 19 and 20 in a direction shown by an arrow A shown in Fig. 16, to facilitate the suctional holding of the leading edge portion of the film lB on the leading end portion 6D of the plate 6 and prevent the film from undergoing a wrinkle or the like. While the film lB is automatically an continually cut off and stuck to the base pates 22 conveyed one after another, the leading edge portion of the film cut off by the rotary cutter is held on the leading end portion 6D of the main vacuum suction plate 6 by suction.
The leading edge of the base plate 22 conveyed in the base plate conveyance passage I-I by the driving and driven rollers 23A and 23B of the base plate conveyor is stopped in the film sticking position. For the stoppage, the leading edge of the base pate 22 is detected by a sensor provided at the base plate conveyor and the driving rollers 23A is stopped on the basis of a detection signal sent cut from the sensor.
Aftex that, the leading end portion 6D of the main vacuum suction plate 6 is moved to the vicinity of the film sticking ~2~198 surface of the leading edge portion of the stopped base pate 22 in a direction shown by an arrow C in Fig. 17, to feed the leading edge portion of the film to the film sticking position.
The leading end portion 6D of the main vacuum suction pate 6 holding the film lB by suction is then moved to the film and pushed onto the film sticking surface of the leading edge portion of the base plate 22 so that the leading edge of the film is stuck, under pressure, to the base plate, as shown in Fig. 18. After that, holding the stratified film lB on the main vacuum suction plate 6 by suction is ceased, and the leading end portion 6D of the plate is moved back from the film sticking position, as shown in Fig. 19. After the main vacuum suction plate 6 is thus moved back to a position shown in Fig.
20, the support member 8 coupled to the main vacuum suction plate is moved away from the base plate conveyance passage I-I
so that the main vacuum suction plate and the holding member 12 are moved further away from the base plate 22. At that time, the support member 14 for the fixed cutting member 15 remains where it is. After moving the main vacuum suction plate 6 to the position farthest from the base plate 22 as shown in Fig.
20 is completed, the support member 14 for the fixe cutting member 15 and the film holding member 12 are moved to the vicinity of the stratified film lb from behind it. Moving the heat and pressure sticking roller 21 from a put-aside position to the film sticking position in a direction shown by an arrow D in fig. 19 is started on the basis of that movement of the support member 14 and the holding member 12. When the roller 21 is moved to the film sticking position, it comes into contact with the leading edge of the stratified film IB under appropriate pressure. Because of the rotation of the roller 21 and the resumption of the rotation of the driving rollers 23A
of the base pate conveyor, the base plate 22 is conveyed, and sticking the film lB, under heat and pressure, to the base pate by the roller is started. The roller 21 is rotated to automatically stick the stratified film lB by a prescribed length to the film sticking surface of the base plate 22 from the leading edge thereof toward the trailing edge thereof while feeding the film to the base plate. The film lB is pulled out from the supply roller 2 by the roller 21 while the roller sticks the film to the base plate and moves the plate in the direction of the conveyance thereof.
When it is detected by a sensor provided at the base plate conveyance passage that the trailing edge of the stratified film lB has come to a prescribed position at the base plate conveyor, a detection signal is sent out from the sensor so that moving the main vacuum suction plate 6 and the film holding member 12 toward the base plate conveyance passage I-I
by a motor is started on the basis of the detection signal to equalize the speed of the movement of the suction plate and the holding member to that of the sticking of the film lB and hold the film by suction. At the time of that holding of the film lB by the suction, rotating the rotary cutting member 17 of the ~26~98 rotary cutter from the initial position thereof toward the movement passage for the film is started. The main vacuum suction plate 6 and the film holding member 12 are moved to the vicinity of the support member 14 for the fixed cutting member 14 while holding the stratified film lB by suction. When the distance between the film holding member 12 and the support member 14 has becomes a prescribed very small value, the cutoff of the film lB is completed. Presetting is performed so that the length of the film lB from the cutting edge of the fixed cutting member 15 to the boundary between the body and leading end portion of the main vacuum suction plate 6 at the time of the completion of the cutoff the film is equal to that of a film leading edge portion winding area. Presetting is performed so that the length of the stratified film lB from the film pushing point of the heat and pressure sticking roller 21 to the trailing edge of the film, which is generated as a result of the cutoff of the film by the rotary cutter, is substantially equal to that of the portion of the surface of the base plate 22, which is not yet stuck with the film. The trailing edge of the stratified film lB shown in Fig. 21 responds to that of the base plate 22. After the cutoff of the film lB, the main vacuum suction plate 6 and the film holding member 12 are at a standstill while holding the continuous stratified film by suction.
The trailing edge of the cut-off stratified film lB is stuck to the film sticking surface of the base plate 22 at the ~2~198 trailing edge thereof by the heat and pressure sticking roller 21. The leading edge portion of the continuous stratified film lB is gradually stuck, under heat ancl pressure, to the base plate 22 from the leading edge thereof toward the trailing edge thereof because of the rotation of the heat and pressure sticking roller 231 and the conveyance of the base pate. Since the air is blown from the air blowoff pipe 20 to the trailing edge portion of the cut-off stratified film lB in a direction shown by an arrow F in Fig. 21 and the vacuum suction bar 25 sucks the trailing edge portion of the film so that the portion passes while xubbing the bar, appropriate tension is applied to the film before the heat and pressure sticking thereof so that the film is prevented form undergoing a wrinkle or the like while belng stuck, under heat and pressure, to the base plate 22. The cut-off trailing edge of the stratified film lB is stick to the film sticking surface of the base plate 22 at the trailing edge thereof, thus completing the heat and pressure sticking of the film to the base plate. When the length of the unstuck trailing edge portion of the stratified film lB has become small immediately before the completion of the heat and pressure sticking of the film to the base plate 22, the vacuum suction bar 25 is revolved around the heat and pressure sticking roller 21 toward the base plate and sucks the unstuck trailing edge portion of the film until immediately before the completion of the sticking, to apply appropriate tension to the film to prevent it from undergoing a wrinkle or the like. The 2~2~
base plate 22 stuck with the stratified film ls under heat and pressure is conveyed, by the base plate conveyor, to an exposure apparatus installed next to the sticking apparatus.
The vacuum suction bar 25 is thereafter revolved back to the original position thereof around the heat and pressure sticking roller 21 in such a direction that the bar goes away from the base plate conveyance passage I-I. The upper and the lower heat and pressure sticking rollers 21 are moved along the direction of the conveyance of the base pla~e 22 so that the rollers are opened from each other and moved away from the film sticking position.
Since the chip made from the stratified film lB during the sticking thereof is removed as described above, it is less likely that such a chip is left as a contaminant on the surface of the base plate, on that of the film, between them or/and in the body of the sticking apparatus. This results in enhancing the yield in the sticking of the film. As descried above, the stratified film lB is cut off at the leading edge portion thereof rectangularly to the direction of the feed thereof for the first sticking of the film to the base plate 22. The leading edge portion of the film lB is thereafter sucked on the leading end portion 6D of the main vacuum suction plate 6 is moved to the vicinity of the leading edge of the film sticking surface of the base plate 22 conveyed to the film sticking position, so that the leading edge of the film lB is fed to the base plate. The leading edge of the film lB is stuck to the - 2~ -2~2&~L~8 film sticking surface of the base plate 22 at the leading edge thereof in the film sticking position. The suction of the film lB on the main vacuum suction plate 6 is ceased. The suction plate 6 is moved from the film sticking surface of the base plate 22. The film lb is gradually stuck to the base plate 22 form the leading edge of the film by the heat and pressure sticking roller 21 while being fed to the base plate by the roller. The film lB is sucked as the speed of the feed of the base plate 22 and that of the movement of the main vacuum suction plate 6 are equalized to each other. The film lB is cut off hy the rotary cutter rectangularly to the direction of the feed of the film without being loosened, so that the film has the trailing edge thereof and the length of the cut-off film corresponds to that of the base plate 22. The cut~off trailing edge of the film lB is stuck to that of the base plate 22 by the heat and pressure sticking roller 21. Thus, the stratified film lB of large width is ~uickly cut off rectangularly to the direction of the feed thereof without being loosened, and is then stuck to the base plate 22.
Since the stratified film lB is cut off at the trailing edge portion thereof by the rotary cutter extending obliquely across the direction of the feed of the film at the prescribed angle thereto depending on the speed of the feed of the film and that of the rotation of the rotary cutter, the film is cut off at the trailing edge portion thereof rectangularly to the direction of the feed of the film without being loosened, 50 202~ 98 that the length of the cut-off film corresponds to that of the base plate 22.
The rotary cutting member 17 of the rotary cutter is borne by the support member 16 and rotatably supported at both the ends of the rotary cutting men~er by the slide members 105 movable backward and forward to and from the front of the stratified film lB. The fixed cutting member 15 of the rotary cutter is provided near the film holding member 12, on which the leading edge portion of the film lB is wound. As a result, the fixed and the rotary cutting members 15 and 17 of the cutter can be opened from each other in preparation of cutting off the stratified film lB for the first time, to make it easy to layer the film through between the fixed and the rotary cutting members.
The film lB is quickly and securely cut off by the rotary cutter without imparting a shock to the components of the sticking apparatus around the cutter.
The present invention is not confined to the embodiment described above~ but may be practiced or embodied in other various ways without departing from the spirit or essential character thereof.
According to the present invention, a chip made from a film during the sticking thereof is removed to make it less likely that such a chip is left as a contaminant on the surface of a base plate, on that of the film, between them or/and in the 2 Q ~
body of a sticking apparatus. This results in enhancing the yield in the sticking of the film.
STICKIN(~ APPARAlllS
BACKGROUND OF THE INVENTION
The present invention relates to a film sticking art, particularly to a film sticking art in which a film having a length corresponding to that of a base plate or panel is stuck to the film sticking surface of the plate.
A process in which a printed circuit board for an electronic machine such as a computer is manufactured includes a procedure in which a stratified body is stuck to the surface of a base plate or panel for the board. The stratified body consists of a light-transmissible resin film and a photosensitive resin layer which is a resist layer. The photosensitive resin layer is directly stuck to the surface of the base plate. The light-transmissible resin film is provided on the photosensitive resin layer to protect it. The sticking of the stratified body to the base plate is performed by a sticking apparatus as disclosed in the Japanese Patent ~pplication (OPI) No. 117487/88 made by the present applicant.
The procedure in which the stratified film is stuck to the base plate by the apparatus is described from now on. The base plate is first conveyed by a base plate conveyance mechanism so that the leading edge of the base plate with regard to the direction of the conveyance thereof is stopped in the position of the sticking of the film. The light-transmissible resin film side of the leading edge portion of the long continuous 2~2~8 stratified body fed from a film supply roller is then sucked by a main vacuum suction plate which is a film feed member. A
film tentative sticking member is provided at the leading end of the main vacuum suction plate, which is located nearer the film sticking position than the other end of the suction plate, so that the leading edge portion of khe stratified body is sucked on the film tentative sticking member. The film tentative sticking member has suction holes communicating with a vacuum suction unit for sucking the stratified body, and has a heater provided in the member itself so as to tentatively stick the leading edge of the stratified body to the base plate. The main vacuum suction plate and the film tentative sticking member are moved to the vicinity of the film sticking position, namely, to the vicinity of the surface of the lading edge portion of the base plate. The leading edge of the stratified body is then put into contact with the film sticking surface of the leading edge portion of the base plate, and tentatively stuck thereto under heat and pressure by the tentative sticking member. The main vacuum suction plate and the tentative sticking member are thereafter put out of sucking action and moved away from the film sticking position. At that time, since the leading edge of the stratified body is already tentatively stuck to the surface of the base plate, the leading edge does not deviate from the films ticking position. A head and pressure sticking roller is then moved to the vicinity of the film sticking position while being rotated, so that the 2 ~ 8 tentatively stuck portion of the stratified body is pressed by the roller. Because of the rotation of the roller, the stratified body is gradually stuck, under heat and pressure, to the surface of the base plate and the base plate is conveyed forth further. The stratified body is automatically fed to the films sticking position because of the rotation of the heat and pressure sticking roller and the conveyance of the base plate.
During the heat and pressure sticking of the stratified body to the surface of the base plate by the roller, the trailing edge of the base plate is detected so that a detection signal is generated. The continuous stratified body is cut off on the basis of the detection signal so that the cut-off body has the trailing edge thereof and the cut-off length of the body corresponds to that of the base plate. For the cutoff of the stratified body, a cutter is moved in a direction across that of the feed of the stratified body as an auxiliary vacuum suction plate provided at a stratified body feed passage holds, by suction, the stratified body at its portion to be cut off.
The cutter is a disk-like cutter. The cut-off trailing edge portion of the stratified body is guided to the trailing edge portion of the base plate as a vacuum suction bar which is a film trailing edge suction member holds the trailing edge portion of the stratified body by suction so that appropriate tension is applied to the body. The trailing edge portion of the stratified body is stuck, under heat and pressure, to the surface of that of the base plate by the heat and pressure 2~2~9~
sticking roller. The base plate thus stuck with the stratified body by the sticking apparatus is conveyed to an exposure apparatus installed next to the sticking apparatus. Such a kind of a film sticking art in which a stratified body is tentatively stuck at a portion thereof to a base plate and thereafter stuck thereto under heat and pressure was also disclosed in the West German Patent DE 3334009 C2, the Japanese Patent Application No. 59169/87 and so forth.
The above-mentioned procedure in which the stratified body is stuck to the base plate includes a step in which the stratified body is cut off by the cutter during the sticking of the stratified body to the base plate by the heat and pressure sticking roller so that the cut-off stratified body has the trailing edge thereof. At the time of the cutoff, a chip is made from the stratified body and flies away to contaminate the ambience in such a manner as to cling to the surface of the base plate, that of the stratified body or the like. The portion of the base plate or the stratified body, to which the chip is clinging, is likely to become a defective portion to increase the number of defective base plates to lower the yield in the sticking. This is a problem.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide film sticking art in which the contamination by a chip made from a film at the time of cutting thereof is reduced.
2 ~ 2 ~
It is another object of the present invention to provide an art in which the yield in the sticking of a film is enhanced.
The above-mentioned and other objects and novel features of the present invention will be apparent from the description herein and the drawings attached hereto.
In order to attain the above-noted and other objects of the invention, according to the invention, there is provided a sticking apparatus for sticking a continuous film to a film sticking surface of a base plate from a leading edge thereof toward a trailing edge thereof, comprising: a cutter means for cutting off said film during said sticking of said film so that the cut-off film has a length corresponding to that of said base plate; a holding member provided at a feed passage for said film near a position of said cutoff for holding said film near its portion to be cut off, said cutter means being provided in such a position that said cutter means faces said holding member across said film held by said holding member;
and a chip suction means provided near said position of said cutoff for sucking a chip made from said film at the time of said cutoff of said film.
Since the chip made from the film during the sticking thereof to the base plate is removed by the chip suction means of the sticking apparatus provided in accordance with the present invention, it is less likely that such a chip is left as a contaminant on the surface of the base plate, on that of the film, between the base plate and the film or/and in the 2Q~98 body of the apparatus. This resuits in enhancing the yield in the sticking of the film to the base plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
An embodiment of the present invention is hereafter described in detail with reference to the accompanying drawings.
In a sticking apparatus according to the invention, three-layer stratified films 1 each consisting of the light-transmissible resin film, the photosensitive resin layer and another light-transmissible resin film are continuously wound on supply rollers 2 is advance. The stratified film 1 from 202~198 each of the supply rollers 2 in advance. The stratified film 1 from each of the supply rollers 2 is separated, by a film separation member 3, into the light-transmissible resin film lA
as a protective film and the stratified film lB consisting of the other light-transmissible resin film and the photosensitive xesin layer exposed on its side to be stuck to the base plate.
The effective length of the film separation member 3 is not less than the maximum width of films to be stuck by the sticking apparatus. The separation edge portion of the separation member 3 is shaped as a wedge. For that reason, the resistance to the separation of the light-transmissible resin film lA and the stratified film lB by the separation member 3 is so low and the fluctuation of the point of the separation is so small that the films lA and lB can be smoothly separated from each other by the member.
The light-transmissible resin film lA separated from the stratified film lB is wound on a winding roller 4. A pair of such winding rollers 4 are provided over and under the base plate conveyance passage I-I as well as the supply rollers 2.
The leading edge of the separated stratified film lB is fed to the main vacuum suction plate 6, which is a film feed member, along a tension roller 5, as shown in Fig. 2.
As shown in Fig. 6, the main vacuum suction plate 6 is made of a magnetic substance such as iron, alumina or the like. The body of the plate 6 has suction grooves 6G and suction holes 6H, which communicate with a vacuum suction system for sucking ~2~
the stratified film ls on the plate. The leading end portion 6D of the plate 6 also has such suction grooves and such suction holes. The plate 6 is vertically moved toward and away from the position Gf the sticking of the film lB, as shown in Fig. 2. The plate 6 is slidable fitted on guide rails 7 attached to a support plate 8 for the plate 6, as shown in Fig.
6. The support plate 8 is coupled with a rac~ and a pinion 10 to a mounting frame 601 attached to the casing of the sticking apparatus, so that the support plate can be vertically moved.
The pinion 10 is engaged with a rack 602 provided on a vertically moving rod 603 coupled to a driving motor 11. The rack 602 is vertically moved by a push roller 604 having a rotary shaft 604A attached to the mounting frame 601. The support plate 8 is coupled to the film holding member 12 which is for winding the leading edge portion of the stratified film lB to cut it off and is slidable fitted on horizontal guide rails 605.
The film holding member 12 has suction grooves 12G and suction holes 12H, which communicate with the vacuum suction system for sucking the stratified film lB, as shown in Fig. 6.
The longitudinal edge area 12R of the film holding member 12, which is located nearer the fixed cutting member 15 of the rotary cutter than the other longitudinal edge area of the holding member 12, does not have any of the suction grooves 12G
but some of the suction holes 12H, so that the stratified film lB can be securely held by the holding member 12. If the area 2a2g~ ~
12R had such a suction groove, it would be likely that the continuous stratified film lB fed from the film supply roller 2, cut off by the rotary cutter and held by the film holding member 12 did curl at the leading edge of the film due to the suction groove and the leading edge did project outward to lower the security of the holding of the film by the film holding member 12. The holding member 12 is provided with coupling notched members 606 in which coupling rods 13 are fitted. The coupling rods 13 are attached to a support member 14 for the fixed cutting member 15 of the rotary cutter, as shown in Figs. 1 and 6. The fixed cutting member 15 and 15A of the rotary cutter is supported by the support member 14 attached to slide members 101 which are for sliding the support member 14 and are slidable fitted to rotary cutter support members 102 so that the slide members 101 are moved backward and forward by pneumatic cylinders 103A and 103B. A member 104 for adjusting the position of the fixed cutting member 15 is provided in a prescribed position on the piston rod of the pneumatic cylinder 103A. Slide member 105 for a support member 16 for the rotary cutting member 17 of the rotary cutter are slidable fitted to the rotary cutter support member 102 so that the slide members are manually moved backward and forward.
A rotary cutter angle adjuster 106, which is a pneumatic cylinder secured to the mounting frame 100 of the casing of the sticking apparatus, is provided at one end of each rotary cutter support member 102. A rotary cutter horizontal or ~ ~ 2 s~
oblique position angle setting member 107 is provided on each rotary cutter support member 102 near the rotary cutter angle adjuster 106 and secured to the mounting frame 100. A rotary cutter an~le adjustment pin 107A is provided to adjust the angle of the rotary cutter to put it in a horizontal or oblique position.
The support member 16 for the rotary cutting member 17 of the rotary cutter is attached to the slide members 105. The rotary cutting member 17 is rotatably supported by the support member 16 and has a cutting portion 17A obliquely extending at a prescribed angle. Brake xings 17B for the fixed cutting member 15 of the cutter are provided on the rotary cutting member 17 at both the ends thereof.
As shown in Fig. 3, a servomotor 108 for rotating the rotary cutting member 17 by a prescribed angle is provided at one end of the support member 16 for the rotary cutting member.
A gear 108A is mounted on the rotary shaft of the servomotor 108 and engaged with a gear 108B mounted on the rotary shaft of the rotary cutting member 17. Positioning engagement knobs 109 for the rotary cutter are provided at both the ends of the support member 16 so that the slide members 105 for the sl1pport member 16 for the rotary cutting member 17 are positioned and locked by the knobs when the rotary cutter is put in and out of use. When the rotary cutter is put out of use as in laying the stratified film lB through between the fixed and rotary cutting members 15 and 17 of the cutter for the first time, the positioning engagement knobs 109 are manually pulled out and the slide members 105 for the support member 16 for the rotary cutting member are then moved forward so that the rotary cutting member is much opened from the fixed cutting member.
The knobs 109 are then pushed into fitting holes at the sides of the knobs so that the slide members 105 are positioned and locked.
Air blowoff pipes 19 and 20 for blowing air to the stratified film lB are provided over and under the support member 16 for the rotary cutting member 17. The side of each of the pipes 19 and 20, which faces the stratified film lB, has a large number of air blow-off holes at the interval of about 20 mm in the longitudinal direction of the pipe. The pipes 19 and 20 are secured to attaching members on the support member 1~ for the rotar~ cutting member 17 so the pipes extend rectangularly across the direction of the feed of the stratified film lB when the pneumatic cylinders 106A and 106~
constituting the rotary cutter angle adjusters are driven in directions as shown by arrows in Fig. 11, to set the fixed cutting member 15 at a prescribed oblique angle to the direction of the feed of the stratified film. For that reason, the air is blown to the film lB uniformly with regard to the width of the film.
Stoppers 110 for positioning the slide members 105 at the time of the use of the rotary cutting member 17 are provided on the support member 102 for the rotary cutter. Positioning 2 ~
screws 111, which are stopped by the stoppers 110, are provided on the slide members 105 at both the ends thereof.
Fig. 7 shows the positional relation between the fixed and rotary cutting members 15 and 17 of the rotary cutter. The fixed cutting member 15 is always urged by a spring not shown in the drawings, so that the cutting portion 15A of ~he member is oriented to the base plate conveyance passage I-I.
As shown in Figs. 1, 3 and 8, a chip box 201, into which chips made from the continuous stratified film ls at the time of the cutoff thereof are collected by suction, is provided near the position of the cutoff. The chip box 201 has a suction slot 201A near the cutoff position. A suction duct 202 is connected to the chip box 201 at the prescribed portion thereof and communicates with a suction unit (not shown). The width of the suction slot 201A is S mm to 6 mm, for example.
A filter made of synthetic fibers to catch the chips of the stratified film lB is provided in the suction duct 202. The chip box 201 is supported by a rest 203 secured to the support member 16 for the rotary cutting member 17.
Fig. 9 shows such a chip box 201 for lower stratified film lB under the base plate conveyance passage I-I.
Fig. 2 shows heat and pressure sticking rollers 21, the base plate 22, driving rollers 23A, driven rollers 23B, base plate holding units 24 and vacuum suction bars 25. Each of the base plate holding units 24 includes a base plate holding roller 24A and a pneumatic cylinder 24B for moving the roller 2~2~ 98 up and down. When it is detected by a base plate leading edge position sensor, which is provided near the base plate conveyance passage but not shown in the drawings, that the base plate 22 is conveyed to a position in which the stratified film lB is tentatively stuck to the base plate, a detection signal is sent out from the sensor so that the rotation of the driving rollers 23A is stopped on the basis of the detection signal.
At the same time, the base plate holding rollers 24A are stopped. Immediately after the leading edge of the base plate 22 has passed under the base plate holding roller 24A, the pneumatic cylinder 24B is put into action on the basis of a detection signal so that the base plate 22 is held by the holding unit 24. The movement of the base plate 22 is thus stopped by the base plate holding roller 24A surely. For that reason, even if the leading end portion 6D of the main vacuum suction plate is not moved, thus maXing it possible to tentatively stick the stratified film lB to the base plate securely. Holding the base plate by the roller 24A is performed until the heat and pressure sticking roller 21 comes into contact with the base plate. The pneumatic cylinder 24B
is put out of action synchronously with the sticking roller's coming into contact with the base plate 22.
The cutoff of the continuous stratified film lB in the sticking apparatus is briefly described from now on. The positioning engagement knobs lO9 are manually unlocked. The support member 16 for the rotary cutting member 17 of the - ~2~
rotary cutter is then pulled out forward so that the rotary cutting member is much opened from the fixed cutting member 15 of the rotary cutter. After that, the leading edge of the stratified film lB separated from the light-transmissible resin film lA by the film separation member 3 is manually put in front of the main vacuum suction plate 6, the film holding member 12 and the fixed cutting member 15, and the film is held on the main vacuum suction plate 6 and the film holding member 12 by suction. At that time, the leading edge of the film lB
is located nearer the base plate conveyance passage I-I than the film holding member 12. If the width of the film ls is smaller than the length of the suction groove 6G of the main vacuum suction plate 6 and that of the suction groove 12G of the film holding member 12, the suction grooves would be partly exposed at the side edges of the film held on the suction plate and the holding member by suction, to let external air flow into the suction grooves to reduce the sucking forces of them on the film. To prevent the reduction in the sucking forces, the portions of the suction grooves 6G and 12G, which are exposed at the side edges of the film lB, may be sealed with adhesive tapes. If the s~lction plate 6 and the holding member 12 are made of a magnetic substance such as iron, the exposed portions of the suction grooves 6G and 12G may be sealed with magnetic tapes. If some suction holes of the plate 6 and the member 12 are exposed for the above-mentioned reason, the suction holes may be sealed with adhesive tapes or magnetic 2 Q ~
tapes. After the support member 16 is set in a position for the use of the rotary cutting member 17 o the rotary cutter, the positioning engagement knobs 109 are locked again. The support member 16 for the rotary cutting member 17 is then manipulated by driving the pneumatic cylinders 106A and 106B in directions as shown by arrows in Fig. 10, so that the fixed and the rotary cutting members 15 and 17 are set to extend rectangularly across the direction of the feed of the stratified film lB. A switch, which is for cutting off the stratified film lB at is leading edge portion extending slightly nearer the base plate conveyance passage I-I than the film holding member 12 but is not shown in the drawings, is operated to put the rotary cutter into action to cut off the film at the leading edge portion thereof in preparation of sticking the film to the base plate for the first time. At that time, the film lB is cut off at the leading edge portion thereof rectangularly to the direction of the feed of the film.
The pneumatic cylinders 106A and 106B are then driven in the directions as shown by the arrows in Fig. 11, so that the fixed and the rotary cutting members 15 and 17 extend at the prescribed oblique angle to the direction of the feed of the stratified film lB. As a result, the air is blown to the film lB uniformly with regard to the width thereof. A switch for continually cutting off the film lB to perform the first and other following sticking thereof is thereafter operated to continually cut off the film. For the cutoff of the film lB by 2 ~ 9 8 the rotary cutter, the rotary cutting member 17 is rotated so that the fllm is instantaneously nipped by the fixed and the rotary cutting members 15 and 17. The stratified film lB can thus be securely and quickly cut off.
For the cutoff of the leading edge portion of the stratified film in preparation of sticking the film to the base plate for the first time, the support member 15 for the rotary cutting memher 17 of the rotary cutter can be easily pulled out forward by manipulating the positioning engagement knobs 109 and thereafter simply pushed bacXward. The position of the rotary cutting member 17 in use can thus be easily set by using the positioning stoppers 110, the positioning screws 111 and the positioning engagement knobs 109.
Automatically sticking each of the upper and the lower stratified films lB, under heat and pressure, to the base plate 22 by the sticking apparatus is hereafter described with reference to Figs. 12, 13,14, 15, 16, 17, 18, 19, 20 and 21 which are schematic views of a major part of the apparatus in respective steps of the sticking. To manually cut off the continuous stratified film lB at the leading edge portion thereof to true up the leading edge of film, the positioning engagement knobs 109 are pulled out, and the slide members 105 for the support member 16 for the rotary cutting member 17 are pulled in a direction shown by an arrow in Fig. 12, to pull out the support member forward to make a wide space to lay the film through. After the film lB is laid through the wide space, the 2~2~1~8 support member 16 is pushed in to the position in which the stratified film lB is cut off and slide members 105 for the support member are then securely locked by the positioning engagement knobs 109, as shown in Fig. 13. After the rotary cutting member 17 is thus set, the switch for cutting off the film lB for the first time is operated to put the rotary cutter into action to cut off the unnecessary leading edge portion of the film lB rectangularly to the direction of the feed thereof to true up the leading edge of the film. At that time, the support member 14 for the fixed cutting member 15 of the rotary cutter and the support member 16 for the rotary cutting member thereof remain in horizontal positions as shown in Fig. 14.
The trued-up leading edge of the stratified film lB whose leading edge portion is already cut off is held on the film holding member 12 by suction and located in front of the fixed cutting member, as shown in Fig. 15. When automatic sticking the film lB to the base plate 22 is started by selection, the support member 14 for the fixed cutting member 15 and the support member 16 for the rotary cutting member 17 are obliquely shifted by the pneumatic cylinders 106A and 106B so that the support embers extend rectangularly across the direction of the feed of the film.
When it is thereafter detected by the base plate leading edge position sensor provided at a base plate conveyor that the base plate 22 is conveyed to a prescribed position in the base plate conveyance passage by the driving rollers 23A and the driven rollers 23B, the holding mèmber 12 and the fixe cutting member 15 are moved by the pneumatic cylinders 103A and 103B in a direction shown by an arrow B in Fig. 16, so that the holding member and the fixed cutting member extend obliquely across the direction of the feed of the film lB. As a result, the leading edge portion of the film lB is moved so that the portion is held on the leading end portion 6D of the main vacuum suction plate 6 by suction. At that time, the compressed air is blown from the air blowoff pipes 19 and 20 in a direction shown by an arrow A shown in Fig. 16, to facilitate the suctional holding of the leading edge portion of the film lB on the leading end portion 6D of the plate 6 and prevent the film from undergoing a wrinkle or the like. While the film lB is automatically an continually cut off and stuck to the base pates 22 conveyed one after another, the leading edge portion of the film cut off by the rotary cutter is held on the leading end portion 6D of the main vacuum suction plate 6 by suction.
The leading edge of the base plate 22 conveyed in the base plate conveyance passage I-I by the driving and driven rollers 23A and 23B of the base plate conveyor is stopped in the film sticking position. For the stoppage, the leading edge of the base pate 22 is detected by a sensor provided at the base plate conveyor and the driving rollers 23A is stopped on the basis of a detection signal sent cut from the sensor.
Aftex that, the leading end portion 6D of the main vacuum suction plate 6 is moved to the vicinity of the film sticking ~2~198 surface of the leading edge portion of the stopped base pate 22 in a direction shown by an arrow C in Fig. 17, to feed the leading edge portion of the film to the film sticking position.
The leading end portion 6D of the main vacuum suction pate 6 holding the film lB by suction is then moved to the film and pushed onto the film sticking surface of the leading edge portion of the base plate 22 so that the leading edge of the film is stuck, under pressure, to the base plate, as shown in Fig. 18. After that, holding the stratified film lB on the main vacuum suction plate 6 by suction is ceased, and the leading end portion 6D of the plate is moved back from the film sticking position, as shown in Fig. 19. After the main vacuum suction plate 6 is thus moved back to a position shown in Fig.
20, the support member 8 coupled to the main vacuum suction plate is moved away from the base plate conveyance passage I-I
so that the main vacuum suction plate and the holding member 12 are moved further away from the base plate 22. At that time, the support member 14 for the fixed cutting member 15 remains where it is. After moving the main vacuum suction plate 6 to the position farthest from the base plate 22 as shown in Fig.
20 is completed, the support member 14 for the fixe cutting member 15 and the film holding member 12 are moved to the vicinity of the stratified film lb from behind it. Moving the heat and pressure sticking roller 21 from a put-aside position to the film sticking position in a direction shown by an arrow D in fig. 19 is started on the basis of that movement of the support member 14 and the holding member 12. When the roller 21 is moved to the film sticking position, it comes into contact with the leading edge of the stratified film IB under appropriate pressure. Because of the rotation of the roller 21 and the resumption of the rotation of the driving rollers 23A
of the base pate conveyor, the base plate 22 is conveyed, and sticking the film lB, under heat and pressure, to the base pate by the roller is started. The roller 21 is rotated to automatically stick the stratified film lB by a prescribed length to the film sticking surface of the base plate 22 from the leading edge thereof toward the trailing edge thereof while feeding the film to the base plate. The film lB is pulled out from the supply roller 2 by the roller 21 while the roller sticks the film to the base plate and moves the plate in the direction of the conveyance thereof.
When it is detected by a sensor provided at the base plate conveyance passage that the trailing edge of the stratified film lB has come to a prescribed position at the base plate conveyor, a detection signal is sent out from the sensor so that moving the main vacuum suction plate 6 and the film holding member 12 toward the base plate conveyance passage I-I
by a motor is started on the basis of the detection signal to equalize the speed of the movement of the suction plate and the holding member to that of the sticking of the film lB and hold the film by suction. At the time of that holding of the film lB by the suction, rotating the rotary cutting member 17 of the ~26~98 rotary cutter from the initial position thereof toward the movement passage for the film is started. The main vacuum suction plate 6 and the film holding member 12 are moved to the vicinity of the support member 14 for the fixed cutting member 14 while holding the stratified film lB by suction. When the distance between the film holding member 12 and the support member 14 has becomes a prescribed very small value, the cutoff of the film lB is completed. Presetting is performed so that the length of the film lB from the cutting edge of the fixed cutting member 15 to the boundary between the body and leading end portion of the main vacuum suction plate 6 at the time of the completion of the cutoff the film is equal to that of a film leading edge portion winding area. Presetting is performed so that the length of the stratified film lB from the film pushing point of the heat and pressure sticking roller 21 to the trailing edge of the film, which is generated as a result of the cutoff of the film by the rotary cutter, is substantially equal to that of the portion of the surface of the base plate 22, which is not yet stuck with the film. The trailing edge of the stratified film lB shown in Fig. 21 responds to that of the base plate 22. After the cutoff of the film lB, the main vacuum suction plate 6 and the film holding member 12 are at a standstill while holding the continuous stratified film by suction.
The trailing edge of the cut-off stratified film lB is stuck to the film sticking surface of the base plate 22 at the ~2~198 trailing edge thereof by the heat and pressure sticking roller 21. The leading edge portion of the continuous stratified film lB is gradually stuck, under heat ancl pressure, to the base plate 22 from the leading edge thereof toward the trailing edge thereof because of the rotation of the heat and pressure sticking roller 231 and the conveyance of the base pate. Since the air is blown from the air blowoff pipe 20 to the trailing edge portion of the cut-off stratified film lB in a direction shown by an arrow F in Fig. 21 and the vacuum suction bar 25 sucks the trailing edge portion of the film so that the portion passes while xubbing the bar, appropriate tension is applied to the film before the heat and pressure sticking thereof so that the film is prevented form undergoing a wrinkle or the like while belng stuck, under heat and pressure, to the base plate 22. The cut-off trailing edge of the stratified film lB is stick to the film sticking surface of the base plate 22 at the trailing edge thereof, thus completing the heat and pressure sticking of the film to the base plate. When the length of the unstuck trailing edge portion of the stratified film lB has become small immediately before the completion of the heat and pressure sticking of the film to the base plate 22, the vacuum suction bar 25 is revolved around the heat and pressure sticking roller 21 toward the base plate and sucks the unstuck trailing edge portion of the film until immediately before the completion of the sticking, to apply appropriate tension to the film to prevent it from undergoing a wrinkle or the like. The 2~2~
base plate 22 stuck with the stratified film ls under heat and pressure is conveyed, by the base plate conveyor, to an exposure apparatus installed next to the sticking apparatus.
The vacuum suction bar 25 is thereafter revolved back to the original position thereof around the heat and pressure sticking roller 21 in such a direction that the bar goes away from the base plate conveyance passage I-I. The upper and the lower heat and pressure sticking rollers 21 are moved along the direction of the conveyance of the base pla~e 22 so that the rollers are opened from each other and moved away from the film sticking position.
Since the chip made from the stratified film lB during the sticking thereof is removed as described above, it is less likely that such a chip is left as a contaminant on the surface of the base plate, on that of the film, between them or/and in the body of the sticking apparatus. This results in enhancing the yield in the sticking of the film. As descried above, the stratified film lB is cut off at the leading edge portion thereof rectangularly to the direction of the feed thereof for the first sticking of the film to the base plate 22. The leading edge portion of the film lB is thereafter sucked on the leading end portion 6D of the main vacuum suction plate 6 is moved to the vicinity of the leading edge of the film sticking surface of the base plate 22 conveyed to the film sticking position, so that the leading edge of the film lB is fed to the base plate. The leading edge of the film lB is stuck to the - 2~ -2~2&~L~8 film sticking surface of the base plate 22 at the leading edge thereof in the film sticking position. The suction of the film lB on the main vacuum suction plate 6 is ceased. The suction plate 6 is moved from the film sticking surface of the base plate 22. The film lb is gradually stuck to the base plate 22 form the leading edge of the film by the heat and pressure sticking roller 21 while being fed to the base plate by the roller. The film lB is sucked as the speed of the feed of the base plate 22 and that of the movement of the main vacuum suction plate 6 are equalized to each other. The film lB is cut off hy the rotary cutter rectangularly to the direction of the feed of the film without being loosened, so that the film has the trailing edge thereof and the length of the cut-off film corresponds to that of the base plate 22. The cut~off trailing edge of the film lB is stuck to that of the base plate 22 by the heat and pressure sticking roller 21. Thus, the stratified film lB of large width is ~uickly cut off rectangularly to the direction of the feed thereof without being loosened, and is then stuck to the base plate 22.
Since the stratified film lB is cut off at the trailing edge portion thereof by the rotary cutter extending obliquely across the direction of the feed of the film at the prescribed angle thereto depending on the speed of the feed of the film and that of the rotation of the rotary cutter, the film is cut off at the trailing edge portion thereof rectangularly to the direction of the feed of the film without being loosened, 50 202~ 98 that the length of the cut-off film corresponds to that of the base plate 22.
The rotary cutting member 17 of the rotary cutter is borne by the support member 16 and rotatably supported at both the ends of the rotary cutting men~er by the slide members 105 movable backward and forward to and from the front of the stratified film lB. The fixed cutting member 15 of the rotary cutter is provided near the film holding member 12, on which the leading edge portion of the film lB is wound. As a result, the fixed and the rotary cutting members 15 and 17 of the cutter can be opened from each other in preparation of cutting off the stratified film lB for the first time, to make it easy to layer the film through between the fixed and the rotary cutting members.
The film lB is quickly and securely cut off by the rotary cutter without imparting a shock to the components of the sticking apparatus around the cutter.
The present invention is not confined to the embodiment described above~ but may be practiced or embodied in other various ways without departing from the spirit or essential character thereof.
According to the present invention, a chip made from a film during the sticking thereof is removed to make it less likely that such a chip is left as a contaminant on the surface of a base plate, on that of the film, between them or/and in the 2 Q ~
body of a sticking apparatus. This results in enhancing the yield in the sticking of the film.
