Can be composed of, for example, a programmable controller or a relay sequence circuit.

Next, the operation of the embodiment will be described.

The film sticking apparatus according to the embodiment is mainly shown in FIG.
Operate according to the procedure of 13 .

First, the laminated film 1B is manually set in the preparation state for starting the attachment (step 1). That is, the supply roller 2 on which the sufficient three-layer laminate film 1 is wound.
Is installed in this film sticking device. This supply roller 2
At the time of installation, first place the supply roller on each of the bearing cam followers 92L and 92R, and then press the shaft retainer 94A of the brake part.
Is advanced to fit the concave portion of the shaft 2A and the convex portion of the shaft retainer 94A.

Then, the three-layer laminate film 1 is passed from the guide roller 32 to the film separating member 3 to separate it into the translucent resin film 1A and the laminate film 1B. Laminated film 1 separated by the film separating member 3
B is sent from the main vacuum plate 56 to the tip of the cutter 62. In this case, the rotary blade 62A of the cutter 62 can be manually separated from the fixed blade 62B, and the laminated film 1B is passed between them.

Next, the laminated film 1B is cut with the cutter 62.
To cut (step 2). That is, the rotary blade 62A and the fixed blade 62B are not tilted and are manually rotated.
The film 1B is cut by rotating A. In this case, the turn knob 96A of the positioning mechanism 96 is turned to adjust the horizontal position of the supply roll 2 so that the central axis of the laminated intermediate film 1B is aligned with the central axis of the substrate 6. In addition, it can be adjusted before cutting.

Then, the main vacuum plate 56,
The pressure roller 28 and the like are set to the original position (step 3). In this case, the main vacuum plate 56 is lowered to some extent from the rising end, and the main vacuum plate 56 and the film transporting surface side of the leading end winding film holding member 60 are aligned.

Then, the automatic operation is started (step 4).

[0083]

On the other hand, when the substrate 6 is conveyed in the substrate loading section 20 and the substrate 6 is detected by the width-shift start position sensor S1, the substrate 6 is width-shifted by the width-shift device 42. , A predetermined width direction position.

The width-adjusted substrate 6 is advanced in the transport direction.
Then, the front end of the substrate is detected by the substrate rear end detection sensor S2.
(Step 5), the film holding member 60 becomes a substrate.
Move in the transport direction. This allows the main vacuum pump
The laminated film 1B is attached to the temporary attachment portion 56A at the tip of the rate 56.
Is wound (step 6). Then, the tip of the substrate
When the board edge detection sensor S3 detects
Therefore, the count of the counter of the central control unit 120
start. This count is based on the preset time.
And stops the leading end of the substrate 6 in the transport direction at the temporary attachment position.
Let it.

The main vacuum plate 56
Until the board moves forward and is temporarily attached,
The substrate pressing member 44 is driven to move downward in the direction of the substrate 6, and the substrate 6 is pinched together with the drive roller 38. Further, the air bubble prevention liquid is applied to the advancing substrate 6 by the wet roller 48.

Next, by advancing the main vacuum plate 56, the laminated film 1B is temporarily attached to the substrate 6 (step 7).

That is, while the other counter is operating,
The upper and lower main vacuum plates 56 are advanced toward the upper and lower surfaces of the substrate 6 by driving a main vacuum plate driving servomotor (not shown) while being synchronized by the rack gear 68 and the pinion gear 70.
In this case, the driving of the main vacuum plate driving servomotor is stopped at a position, for example, 2 cm before the upper and lower surfaces of the substrate 6. Thereafter, the upper and lower main vacuum plates 56 are moved forward by the driving force of the main vacuum plate driving air cylinder (not shown), and the temporary attachment portion 56A
Are brought close to the upper and lower surfaces of the substrate 6. At this time, a temporary pressing force is applied by a pair of air cylinders provided at both ends in the main vacuum plate width direction (along the laminate film 1B width direction). Therefore, the laminated body film 1B can be temporarily attached to both surfaces of the substrate 6 with the same force. In addition,
At this time, driving force of the servo motor, peak Niongiya 7
It is not transmitted to 0.

Next, the main vacuum plate 56 is retracted in the direction away from the substrate 6, and the pressure bonding roller 28 is advanced so as not to interfere with the temporary fixing portion 56A of the main vacuum plate 56, and the pressure bonding roller 28 is moved. The pressure bonding of the temporarily fixed laminated film 1B is started (step 8).

Next, when the laminated film 1B is pressure-bonded by the pressure roller 28 and the rear end of the laminated film 1B to be attached to the substrate 6 reaches the position of the cutter, the laminated film formed by the main vacuum plate 56. 1B adsorption and the film 1B by the cutter 62
Is cut (step 9).

That is, the laminated film 1B is fed in the feeding direction.
Give the cutter 62 an inclination so that it can be cut at a right angle.
You. In addition, depending on the supply speed of the laminated film 1B,
The rotary blade 62A is rotated in the supply direction. This disconnection
The laminate film 1B is cut at a right angle to the transport direction.

The laminated film 1B is guided by the support roller 64 during and after cutting. Therefore, even if the pressure roller 28 has a small diameter, the laminated film 1B is sent without sliding on the fixed blade 62B.
Further, suction of the vacuum bar 76 is started during the pressure bonding and after the cutting, and the vacuum bar 76 slides on the outer peripheral surface of the laminated film 1B while adsorbing the laminated film 1B to perform thermocompression bonding. When it comes close to the rear end portion of the laminate film 1B to be thermocompression bonded, the vacuum bar 76 pivots around the pressure bonding roller 28 so as to approach the substrate 6, and the suction operation is performed until just before the thermocompression bonding is completed. I do. As a result, a proper tension is applied to the laminated film 1B to prevent wrinkles and the like from occurring in the laminated film 1B (step 9). After the laminated film 1B is cut by the cutter 62, the main vacuum plate 56 and the tip winding film holding member 60 perform a suction operation to suck and hold the laminated film 1B.

Then, it is judged whether or not the thermocompression bonding operation of the laminated film 1B is continued. If continuing, the crimping operation is continued from step 5. If the operation is not continued, the work is finished.

In the above embodiment, the present invention was carried out with the film sticking apparatus having the structure shown in FIG. 1 or 2, but the scope of the embodiment of the present invention is not limited to this.
