Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a method and apparatus for continuously feeding flat articles at regular intervals to a processing apparatus or the like while continuously feeding the flat articles.

As an example, the present invention relates to the production of printed circuit boards, and in particular to a laminating device that continuously laminates a photoresist-like dry film or a protective film onto a printed circuit board substrate (including those without or already formed with a wiring pattern). This method can be effectively applied to feeding printed circuit boards, and the following explanation will be based on this example.

In this specification, the substrate of a printed board will be abbreviated as a "printed board" or simply "substrate," and a dry film-like photoresist or protective film will be referred to as a "photoresist film" or "resist film." Abbreviated.

Background of the Technology In recent years, the mainstream method for manufacturing printed circuit boards is to form a photoresist layer on the surface of a conductor layer of a board such as a copper-clad board, and to form a wiring pattern using photolithography technology. In this case, the method of forming the photoresist layer is mainly by laminating a dry film of photoresist on the surface of the substrate.

Previously, resist film was laminated onto printed circuit boards by cutting a long strip of resist film to the length of the board and then laminating the resist film one by one, but this method was inefficient and hindered mass production. Missing.

Therefore, in recent years, a laminating apparatus has been developed that can continuously laminate a resist film in the form of a long strip onto a printed circuit board without cutting it. This laminating device is
The printed circuit board is continuously fed with a feed roller or the like at intervals, while a long strip of resist film is continuously supplied and laminated by continuous thermocompression bonding on the surface of the printed circuit board with a laminating roll. has been done.

However, in such a laminating apparatus, the interval between the printed circuit boards supplied to the laminating apparatus from the preceding printed circuit board processing section or printed circuit board stocking section becomes an important issue. That is, the printed circuit boards laminated with resist films in the above laminating apparatus are sent out from the laminating apparatus while being interconnected by the resist films. Therefore, it is necessary to separate the substrates one by one by cutting the resist film between each substrate.
In this case, if the gap between the substrates is too narrow, the film cannot be cut properly, and if the gap is too wide, the edges of the resist film protruding from the substrate after cutting are likely to turn over or wrap around. As a result, problems occur in the subsequent photolithography process, resulting in poor quality of printed boards and a decrease in yield.

OBJECTS OF THE INVENTION In view of the above circumstances, the present invention provides a method and apparatus for feeding flat articles such as printed circuit boards at regular intervals, which can continuously feed flat articles such as printed circuit boards at regular intervals to a processing device such as a laminating device.

FIG. 3 is a plan view and a side view, respectively, schematically showing the overall configuration. In these figures, the reference numeral l indicates the entire laminator, and the laminator 1 basically consists of a timing section 2, a laminating section 3, and a cutting section 4. Further, reference numeral 5 in FIGS. 2 and 3 indicates a board supply unit that supplies the printed circuit board P to the laminator I from the preceding stage printed board processing unit or printed board stock unit (not shown).

First, the overall structure and operation of each part 2, 3.4 of the substrate supply part 5 and laminator 1 will be briefly explained with reference to FIGS. 2 and 3. The substrate supply unit 5 horizontally transports the substrate P in the direction of an arrow A along a horizontal feeding path T (indicated by a dashed line in FIG. 3) using a pair of feeding belts 7 wound horizontally around a pulley 6. It is configured to be fed through a free support roller 8 to a timing adjustment section 2 of a laminator I.

The timing adjustment unit 2 of the laminator l is fast-forwarding ue=W

Be/Lz)11. The device is equipped with a substrate constant interval feeding device according to the present invention having a stopper 17, guide rollers 18 and 21, feeding rollers 22 and 23, spacing pins, 25, etc. at a predetermined speed V(
For example, it is continuously fed to the next laminating section 3 at a rate of 0.5 to 2 m/min). The device for feeding substrates at regular intervals will be described in detail later with reference to FIGS. 4 to 7.

The laminating section 3 includes feed rollers 31 , 32 , 33
, 34, laminating roll 35, free support roller 3
6. It is equipped with a laminating mechanism having a resist film reel 37, etc., and an escape hole processing mechanism having a goo punch unit 40, etc., and maintains the gap d between the substrate P fed from the timing adjustment section 2 in the previous stage. At the same time, the resist film F in the form of a long strip is continuously fed at a constant speed V.
(clearly marked with hunting in Figure 2) is continuously supplied at the same speed as the feed speed of the substrate, and an escape hole corresponding to the reference hole Hp (Figure 2) of the substrate P is prepared in advance in the resist film F. After processing Hf (Fig. 2), resist film F
are continuously thermocompressed onto both the upper and lower surfaces of the substrate P, and the laminated substrate P and resist film F are sent to the next cutting section 4. That is, the substrate P fed from the timing adjustment section 2 is moved to the feed roller 3 while maintaining the distance d.
1 , 32 , 33 , and 34 are continuously fed through the laminating roll 35 at a constant speed V. On the other hand, a long strip-shaped resist film F is continuously supplied from the upper and lower resist film reels 3°7 to the laminating roll 35,
They are continuously thermocompressed onto the upper and lower surfaces of the substrate P, respectively. Furthermore, the gouer punch units 40 are provided in the supply path of the resist film F at equal distances from each other from the laminating roll 35, and on the other hand, at a position on the way to the laminating roll 35 in the substrate feeding path T, the punch unit 40 is provided with the resist film F in the supply path of the substrate P. Reference hole H
A sensor (not shown) for detecting p is arranged at the same distance from the laminating roller 35 as the gouy punch unit 40, and at the same time as this sensor detects the reference hole Hp, the gouy punch unit 40 punches the resist film. When they are sent to the position of the escape caller 35 at F, they are overlapped as shown in FIG.

The cutting section 4 includes a cutting mechanism including a feeding belt 54 horizontally wound around a feeding roll 51, pulleys 52 and 53, a canter 60, etc., and cuts the laminated substrate P and resist sent out from the laminating section 3. While continuously feeding the film F, the resist film F is cut at the gap between the substrates P, and the substrates P are separated one by one, and are directed to a subsequent substrate processing section or substrate stock section (not shown) as indicated by an arrow B. Send it out as you like. That is, the rows of substrates P interconnected by the resist film F sent out from the laminating section 3 are moved at a constant speed V by the feed roller 51 and the feed belt 54 (however, for practical purposes, the circumferential speed of the belt 54 for feeding is not constant). It is advantageous to make the data a little faster than the speed ■). cutter 6
0 is provided between the feed roller 51 and the feed belt 54, and has a razor-shaped canter blade 65.

This canter blade 65 can be moved up and down as shown in FIG. 3 by a support mechanism and a drive mechanism (not shown), and is also transported at the same speed V in the same direction B as the row of substrates as shown in FIG. It is configured so that it simultaneously crosses it at right angles (the actual trajectory is oblique to the substrate row feeding direction B as shown by the dotted line in FIG. 2). When the gap between the substrates in the row of substrates is detected by a sensor (for example, a photo sensor) not shown between the feed roller 51 and the feed belt 54, the cutter blade 65 descends as shown in FIG. While moving in the direction B at a constant speed V, the resist film F is cut in the gap between the substrates by moving in a direction perpendicular to the direction B.

As a result, the preceding substrate P is separated from the substrate row and sent out in the direction of arrow B by the feeding belt 54. On the other hand, after the cutting is completed, the canter blade 65 is shown at 65' in FIG.
It rises to the position shown by , moves above the substrate array in the opposite direction to the direction used during cutting, and returns to the initial position.

The substrate fixed interval feeding device has a pair of rapid feed belts 11 provided at a front stage near the substrate supply section 5 along the substrate feeding path T (FIG. 5). This fast-forwarding belt 11 is wound horizontally around pulleys 12 and 13, and is driven by a two-speed variable speed motor Ml connected to the boot IJ13 by a belt or chain 14, and is driven by a high-speed V of the substrate P as described later.
, and 2 at low speed V2 (where ■<v, <v)
It is configured to allow various types of fast forwarding. In addition, the code S1,
S2 and S3 indicate sensors for detecting the group viP that is supplied from the substrate supply unit 5 to the fast-forwarding bell) 11 and fast-forwarded, and although these sensors are not clearly shown in the figure, they each consist of a light-emitting element and a light-receiving element. It is a photo sensor.

The fast-feeding belt 11 is mounted on a support base 15 that can be raised and lowered in the vertical direction by a linear motor M2, and has a lower position (initial position) where the upper surface of the belt is lower than the substrate feeding path T, as shown by a solid line in FIG. As shown by the dotted line 11'', the belt can be raised and lowered between an upper position where the upper surface thereof is approximately at the same level as the substrate feeding path T. Its raising and lowering stroke is, for example, 15 to 20 mm. A stopper 17 is arranged near the rear end when the substrate is in the lower position.As will be described later, this stopper 17 is used to stop the substrate P fast-forwarded by the fast-forwarding belt 11 at a predetermined standby position. Note that symbols S4 and S5 indicate sensors for respectively detecting the initial position and the upper position of the fast-feeding belt 11, and these are the aforementioned photosensors or mechanical microswitches.

As shown in FIG. 4, on both sides of the fast-forwarding bell 1-11, there are fixed guide rollers 18 and width adjusting rollers 19 movable in the horizontal direction (arrows Z1, Z2) perpendicular to the substrate feeding path T.
is located. The width adjusting roller 19 is driven by a cylinder SYI using air or the like, and the fast-feeding belt 11
The substrate P in the upper standby position is pressed against the guide roller 18 to set the substrate P in a predetermined position and facing straight in the substrate feeding direction. Note that the spring 20 is for adjusting the substrate pressing force of the cylinder SYI.

As shown in FIG. 5, a clamping roller 21 is provided above the fast-feeding belt 11 and facing the pulley 13 thereof. The clamping roller 21 is always urged downward by a spring 21a, and as will be described later, when the fast-feeding belt 11 rises, it clamps the substrate P placed on it, and cooperates with the fast-feeding belt 11 to clamp the substrate P. P is low speed V,
This is a fast feed method.

A pair of feeding rollers 22 and 23 are arranged downstream of the clamping roller 21, that is, on the side of the laminating section 3. The lower roller 22 is constantly driven by a belt or chain 24 in synchronization with the feed roller 31 of the laminate section 3 (in this embodiment, this is the second feed roller of the substrate constant-space feeding device), and keeps the substrate P at a predetermined speed. You can send 4 by pressing ■.

The upper roller 23 is a cylinder SY2 that uses air etc.
This is a driven roller configured to be able to move up and down. This upper feeding roller 23 is normally located at the upper position (initial position), and the fast-feeding belt 11 and the clamping roller 23
The substrate P that is fast-forwarded can freely pass between the feeding rollers 22 and 23, but as will be described later, when the fast-forwarding of the substrate is finished, the substrate P is moved downward and the substrate P is moved between the lower feeding rollers 22 and 23. The structure is such that the substrate P is clamped between the two and fed at a constant speed. Note that symbols S6, S7, and S8 indicate the above-mentioned photosensors for detecting the substrate P that is fed rapidly or at a constant speed along the feeding path T, and S9 indicates the upper feeding roller. There is a photosensor as described above for detecting the lower position of 23, and 0 indicates a microswitch.

Further, two spacing pins 25 on the left and right (see FIG. 4) are provided at the rear stage of the feeding rollers 22 and 23, that is, on the side of the laminating section 3. The spacing pins 25 are set equal to a predetermined substrate spacing d, and are configured to be inserted into and removed from between the substrates P by being driven up and down by a cylinder SY3 using air or the like. On the other hand, the cylinder SY3 is attached to a slider 28 attached to a horizontal guide rod 27 of a fixed support base 26, so that the spacing pin 25 is connected to the feed rollers 22 and 22 shown in solid lines in FIG.
It is movable parallel to the substrate feeding path T between a front position close to 3 and a rear position close to the feed roller 31 indicated by a dotted line 25'. As will be described later, the spacing pin 25 is normally at the lower front position (initial position), and the rear end of the base FiP is at the spacing pin 2.
5, it is raised as shown in FIG. When the subsequent substrate P is rapidly fed by the fast-feeding belt 11 and the clamping roller 21, the front end of the succeeding substrate P pushes the trailing substrate P as shown by the dotted line 25' in FIGS. 4 and 5, and the rear end of the preceding substrate P is is confronted with. As a result, the distance between the front and rear substrates P is set to d. After that, the spacing pin 25 is removed from between the substrates 2, and the support base 26 and the slider 28
It is returned to the initial position by a return spring 29 stretched therebetween. Incidentally, the reference numeral S10 indicates the above-mentioned photosensor or microswitch for detecting the rear position 25' of the slider 28, that is, the spacing pin 25.

Now, the constant interval feeding of the substrates P by the substrate constant interval feeding apparatus as described above will be explained in detail based on the process diagrams shown in FIGS. 6A to 6 and the time chart shown in FIG. 7. Furthermore, the 6th A
Only related parts are schematically shown in FIG. 6, and FIG. 7 only shows the operations of sensors S1 to 310, motor ML M2, and cylinders SYI to SY3.

(a) First, as shown in FIG. 6A, it is assumed that the fast-feeding belt 11, upper feeding roller 23, and spacing pin 25 are all in their initial positions at the time of startup. In this state, when the first substrate P1 is fed by the feed belt 7 of the supply section 5, the substrate P1 tilts diagonally when it passes more than half the support roller 8, and its front end rests on the fast-feeding belt ll.

fb) As shown in FIG. 6B, when the sensor S1 detects the substrate P1, the fast-feeding belt 11 is driven at high speed by the motor M1, and the substrate P1 is fast-forwarded at the high speed Vl.

[C) Next, as shown in FIG. 6C, when the sensor S2 detects the front end of the substrate PIO, the motor M1 is switched to low speed drive, and the substrate P1 is decelerated to a low speed v2 and hits the stopper 17. Then sensor S3 detects substrate P1,
Motor M1 means fast forwarding.

11 is stopped, and the substrate P1 is kept on standby at that position. At the same time, the cylinder SYI is actuated as shown in FIG.
is driven in the direction of arrow Z1, and the substrate P1 is moved by the guide roller 18.
to set it in place and in the correct orientation.

(dl Furthermore, as shown in FIG. 6D, the motor M2 is actuated by the signal from the sensor S3, and the fast forwarding bell l-11 is moved by the arrow Y1.
The substrate P1 is raised to the upper position as shown in FIG.
It is clamped by a clamping roller 21 at the upper feeding position. Incidentally, when the fast-feeding belt 11 reaches the upper position, it is detected by the sensor S5 and the motor M2 is stopped.

(81) Next, the motor M1 is again driven at a low speed as shown in FIG. It is rapidly fed at a low speed ν2.

(flAnd as shown in FIG. 6F, when the sensor S8 detects the front end of the board P1, the motor M1, that is, the fast-feeding belt 1
1 stops. At the same time, the cylinder SY2 is actuated and the upper feeding roller 23 descends in the direction of arrow Y3, clamps the substrate P1, and starts feeding it at a predetermined speed (2). On the other hand, the lowering of the upper feeding roller 23 is detected by the sensor S9, and the motor M2 is reversely driven by the signal, and the fast forwarding bell 1-11 is lowered as shown by the arrow Y2, and when it returns to the initial position, this is detected by the sensor S4. The motor M2 is then stopped. Furthermore, as shown in FIG. 4, the cylinder SYI is actuated by the signal from the sensor S9, and the width adjusting roller 19 returns to the direction of the arrow Z2.

(g) Next, as shown in Fig. 6G, feed roller 22゜2
The first substrate PL fed at a constant speed at step 3 is fed to the feed roller 31 of the laminating section 3, and then continues to be fed at a constant speed V.

On the other hand, the second substrate P2 is supplied from the substrate supply section 5 to the fast-forwarding belt 11 which has returned to the initial position as described in (a) to IO) above with reference to FIGS. 6A to 6C. It is then fast-forwarded at high speed v1 and low speed v2, and then it is moved to the width and waits at a predetermined position.

(hl and as shown in FIG. 6H, when the rear end of the first substrate P1 passes through the sensor S6, the motor M2 is activated and the (
As in the case of FIG. 6D described in cll, the fast-feeding belt 11 rises and the second substrate P2 is clamped by the clamping rollers 21.

(11) Next, as shown in FIG. 61, when the rear end of the first substrate P1 passes the sensor S7, the cylinder SY3 is actuated, and the spacing pin 25 is raised in the direction of arrow Y5 and inserted between the substrates P1 and 22. At the same time, cylinder SY2 operates,
The upper feeding roller 23 ascends back to the initial position as shown by arrow Y4. At the same time, the motor M1 is again driven at low speed, and the second substrate P2 is moved between the fast-feeding belt 11 and the clamping roller 2.
1 causes fast forward feeding at low speed v2.

(J) Then, as shown in FIG. 6J, the second substrate P2, which is being fed rapidly, follows the first substrate P1, which is being fed at a constant speed, while pushing the spacing pin 25 at the front end (vz>V), It abuts against the rear end of the first substrate P1 via the spacing pin 25.

Thereby, the gap d between the first substrate P1 and the second substrate P2 is set to a predetermined value.

+1 interval When the pin 25 reaches its rear position, this is detected by the sensor SIO, and as shown in the figure, the cylinder S
Y2 operates and the upper feeding roller 23 moves in the direction of arrow Y3^.
It descends and clamps the second substrate P2. At the same time, the cylinder SY3 operates again to remove the spacing pin 25 from between the substrates P1 and P22 in the direction of the arrow Y6. Thereby, the substrates P1 and P2 are continuously fed at a constant speed V while maintaining a predetermined distance d from each other. On the other hand, the spacing pin 25 that has been pulled out downward is returned to the initial position (indicated by the dotted line) in the front direction by the return spring 29 as shown by the arrow X2.At the same time, the lowering of the upper feeding roller 23 is also detected by the sensor S9. , as described above, the fast-forwarding bell) 11 is lowered and returned to the initial position by the motor M2.

TI) After that, the same steps as in the case of the second substrate P2 explained in the above (g) to (k) are repeated for the third substrate P3 (FIG. 6) and subsequent substrates. Incidentally, as is clear from FIG. 7, the sensor S8 is connected to the first substrate P1.
It is only used for detection.

In this way, the substrates P supplied from the substrate supply section 5 are aligned at predetermined intervals in the timing alignment section 2 and are continuously transferred to the laminate section 3 even if there are variations in the substrate spacing at the time of supply. It will be shipped.

As described above, according to the method and apparatus for feeding printed circuit boards at regular intervals according to the present invention, printed circuit boards P can be continuously fed to the laminating section 3 at predetermined intervals. Not only does it enable good lamination, but it also makes it possible to efficiently and effectively cut the resist film after lamination.

Note that although the example of application to a printed circuit board laminating apparatus has been described above, the application of the present invention is not limited to this.
