Description

Laminator and method for adjusting alignment of laminator

The present invention relates to a laminator and a method for adjusting the alignment of the laminator.

Conventionally, a laminator for laminating a resin film or the like on a work such as a substrate has been known.
As such a laminator, for example, a vacuum laminator that continuously laminates a laminate film on a work in a vacuum chamber is known. In a vacuum laminator, a film roll shaft (rotating shaft of a laminated film roll), a laminating roller, a winding roller, and the like are installed in a vacuum chamber, and the film roll shaft and the winding roller are driven to rotate from outside the vacuum chamber.
In addition, the technique regarding a vacuum laminator is described in patent document 1, for example.

JP 2003-118001 A

However, in a vacuum laminator using a roller, it is necessary to strictly adjust the alignment of the roller with respect to the conditions required in the laminating process. For example, it is necessary to set the attitude of the roller (the inclination of the rotation axis) within a predetermined allowable range with respect to the conditions required in the laminating process, and take up the roll to control the position of the edge of the laminate film. It is necessary to adjust the position of the roller in the thrust direction.
At this time, it is necessary to adjust the connection state with the motor that drives the roller from outside the vacuum chamber, which increases the work load in performing the roller alignment work. When the roller is driven by a motor from outside the vacuum chamber, a seal for maintaining a vacuum is provided at a portion where the driving force transmission mechanism penetrates the vacuum chamber, and the seal is maintained even when the alignment of the roller is adjusted. It is necessary to maintain a vacuum.
As described above, in the related art, the alignment of the laminator for performing vacuum lamination cannot be easily adjusted.

課題 An object of the present invention is to make it easier to adjust the alignment of a laminator for performing vacuum lamination.

To solve the above problems, a laminator according to an embodiment of the present invention is:
A vacuum chamber;
A roller installed in the vacuum chamber and used for vacuum lamination,
An alignment adjustment mechanism for adjusting the alignment of the roller,
An actuator for generating a driving force for rotating the roller,
With
The tip of the output-side rotating shaft from which the driving force of the actuator is output is disposed outside the vacuum region, and the tip of the input-side rotating shaft to which the driving force for rotating the roller is input is disposed inside the vacuum region, A tip of the output-side rotation shaft and a tip of the input-side rotation shaft are electromagnetically connected.

According to the present invention, alignment adjustment of a laminator for performing vacuum lamination can be performed more easily.

Further, a dancer roller may be provided instead of the lower tension roller 12B, and the looseness of the lower laminate film may be eliminated by a mechanical structure.
The upper laminating roller 13A and the lower laminating roller 13B are driven to rotate by the transport of the laminating film, and the upper laminating film and the lower laminating film sandwiched between the upper laminating roller 13A and the lower laminating roller 13B are evacuated. Lamination is performed by pressure bonding in an environment.
The take-up roller 14 is supported by a support member 17a fixed to the carriage 17 so that the rotation shaft can rotate. The take-up roller 14 is rotatably driven by the rotation drive motor 23 to take up the laminated film carried out from the upper laminating roller 13A and the lower laminating roller 13B.

It is possible to do. Thereby, as the alignment adjustment, the posture of the winding roller 14 can be adjusted (the inclination of the rotating shaft can be adjusted). Further, each bolt hole of the separate plate 16 is a long hole that is long in one direction (for example, a direction orthogonal to the thrust direction), and the entire separate plate 16 can be moved in parallel in this one direction. Has become.

The carriage 17 is configured to be movable on the separate plate 16 in the thrust direction of the winding roller 14. The separate plate 16 and the carriage 17 can be connected, for example, via a linear guide so as to be linearly movable in the thrust direction.

Further, instead of the

torque adjusting motors

21 and 22, a mechanism (for example, a powder brake or the like) for adjusting the rotational resistance of the upper film roll shaft 11A and the lower film roll shaft 11B may be provided. Also in this case, the tension of the upper laminate film and the lower laminate film sent out from the upper film roll shaft 11A and the lower film roll shaft 11B can be controlled.

[Example of winding roller installation structure]
FIG. 3 is a schematic diagram illustrating an example of an installation structure of the winding roller 14.
The take-up roller 14 has an alignment adjustment function to which the present invention is applied.
As shown in FIG. 3, the take-up roller 14 is rotatably supported by a support member 17a fixed to a carriage 17 inside the vacuum chamber 1A so as to be rotatable. At the tip of the rotating shaft of the take-up roller 14, a disk 14a for magnet coupling is installed, and at the tip of the rotating shaft of the rotation driving motor 23, a disk 23a is placed across the boundary of the vacuum region. And are electromagnetically coupled.

In the present embodiment, the rotating shaft of the take-up roller 14 passes through the partition wall of the vacuum chamber 1A, and the disk 14a provided at the tip of the rotary shaft of the take-up roller 14 has a sealing portion provided outside the partition wall. Within 1B, the disk 23a installed at the tip of the rotation shaft of the rotation drive motor 23 is opposed to the disk 23a with the sealing plate 31 of the seal portion 1B interposed therebetween. The member (here, the sealing plate 31) provided between the disk 14a and the disk 23a is desirably made of a material that does not generate eddy current or a material that hardly generates eddy current. It can be made of a resin that does not generate or a metal such as stainless steel that does not easily generate eddy current.

The seal portion 1B has a structure in which the rotating shaft of the take-up roller 14 seals a through-hole passing through the vacuum chamber 1A. It is installed outside.
The sealing plate 31 is connected to one end of the carriage 17 by a connecting member 33 via a free joint. Therefore, by changing the distance between the sealing plate 31 and the partition of the vacuum chamber 1A, the take-up roller 14 and the disk 14a move in the thrust direction. In this case, as means for moving the take-up roller 14 and the disk 14a in the thrust direction, a separate motor for movement or manual operation can be provided.
As a result, control of the edge position of the laminated film (position adjustment in the thrust direction) is realized as alignment adjustment.

Here, when performing the alignment adjustment of the winding roller 14 (position adjustment in the thrust direction and adjustment of the inclination of the rotation axis), the distance and inclination between the

disks

14a and 23a that are electromagnetically connected are not required to be strict. The shift is allowed within the set range. In the present embodiment, the coupling conditions for the electromagnetically coupled

disks

14a and 23a to be appropriately electromagnetically coupled are as follows: the disk 14a of the take-up roller 14 is adjusted by the alignment adjustment so that the disk 14a of the rotary drive motor 23 is rotated. The maximum value of the amount of deviation occurring with respect to 23a is allowable.
Therefore, according to the vacuum laminator 1 according to the present embodiment, the alignment adjustment of the winding roller 14 can be performed more easily.

In the present embodiment, the rotation shaft of the rotation drive motor 23 is rotatably supported by restricting axial movement of the holding member 34 fixed to the sealing plate 31.
Therefore, in the case of the structure example shown in FIG. 3, when the take-up roller 14 is moved in the thrust direction in order to adjust the edge position of the laminated film, the holding member 34, the disk 23a, the connecting member 33, the carriage 17, The positional relationship among the support member 17a, the take-up roller 14, and the disk 14a is maintained. That is, when the alignment adjustment in the thrust direction is performed, the positional relationship between the disk 14a provided at the tip of the rotation shaft of the take-up roller 14 and the disk 23a provided at the tip of the rotation shaft of the rotation driving motor 23 is determined. When the alignment is maintained, the burden of performing the adjustment work of each part including the state of the electromagnetic connection is reduced.
Further, according to the vacuum laminator 1 according to the present embodiment, a structure that does not generate resistance (rotational friction) to the rotating shaft in the seal portion 1B can be achieved.

[Action]
Next, the operation of the vacuum laminator 1 will be described.
In the vacuum laminator 1, it is necessary to adjust the inclination of the rotation axis of each roller before performing the vacuum lamination.
When adjusting the inclination of the rotation axis of the winding roller 14 (alignment adjustment of the rotation axis), the attitude of the entire winding roller 14 is adjusted by adjusting the jack bolt of the separate plate 16.
At this time, although the positional relationship between the disk 14a of the winding roller 14 and the disk 23a of the rotation driving motor 23 may change, in the present embodiment, the

disks

14a, 23a are electromagnetically connected. Therefore, the strict adjustment of the positional relationship is not required.
Therefore, the work load when performing the alignment adjustment of the rotating shaft of the winding roller 14 is reduced.

In the vacuum laminator 1, the edge position of the laminated film wound by the winding roller 14 is adjusted in conjunction with the adjustment of the inclination of the rotation axis of each roller.
When adjusting the position of the take-up roller 14 in the thrust direction (alignment adjustment in the thrust direction), the holding member 34, the disk 23a, the connecting member 33, the carriage 17, the support member 17a, the take-up roller 14, and the disk 14a are taken up by the take-up roller. By moving the laminated film 14 in the thrust direction, the edge position of the laminated film is adjusted.
At this time, the positional relationship between the disk 14a provided at the tip of the rotation shaft of the take-up roller 14 and the disk 23a provided at the tip of the rotation shaft of the rotation drive motor 23 is maintained, and the alignment adjustment in the thrust direction is performed. In this case, the burden of performing the adjustment work of each part including the state of the electromagnetic connection is reduced.

Further, since it is not required to strictly adjust the positional relationship between the

disks

14a and 23a, even if the positional relationship between the

disks

14a and 23a changes within a certain range, the electromagnetic coupling is maintained and the winding roller 14 The work load when adjusting the alignment in the thrust direction is reduced.
Therefore, according to the present invention, alignment adjustment of a laminator for performing vacuum lamination can be performed more easily.

[Modification 1]
In the above-described embodiment, as shown in FIG. 3, when the take-up roller 14 is moved in the thrust direction, the holding member 34, the disc 23a, the connecting member 33, the cart 17, the support member 17a, the take-up roller 14, The example of the installation structure of the winding roller 14 in which the positional relationship of the disk 14a is maintained has been described.
On the other hand, a motor for moving the take-up roller 14 in the thrust direction is provided, and the rotation driving motor 23 can have an installation structure in which the position is fixed.

FIG. 4 is a schematic diagram illustrating an example of an installation structure of the winding roller 14 according to the present modification.
The installation structure example shown in FIG. 4 mainly includes a thrust adjustment motor 24 for position adjustment in the thrust direction, is connected to the carriage 17, and has a reduction mechanism 141 installed on the rotation shaft of the take-up roller 14. This is different from the installation structure example shown in FIG.
In the example of the installation structure shown in FIG. 4, the rotating shaft of the thrust adjustment motor 24 passes through a through hole formed in the partition wall of the vacuum chamber 1A, and is connected to one end of the carriage 17 via a free joint. In addition, the seal part 1B is installed in the part of this through-hole. However, since the output of the thrust adjustment motor 24 is smaller than the output of the rotary drive motor 23, the size of the seal portion 1B in FIG. 3 can be made smaller.

Further, the rotating shaft of the rotation driving motor 23 is not held by the holding member 34, and the disk 23a faces the disk 14a with the sealing plate 31 interposed therebetween. The sealing plate 31 is directly fixed to the outside of the partition wall of the vacuum chamber 1A without the bellows 32 while maintaining a vacuum. In the case of the structure shown in FIG. 4, the rotation driving motor 23 can be fixedly installed.
The reduction mechanism 141 has a drive force input shaft 141a coupled to the disk 14a, a gear 141b having the drive force input shaft 141a as a rotation axis, and a rotation shaft of the take-up roller 14, and is provided with a gear 141b. And a matching gear 141c.
The input shaft 141a and the gear 141b are rotatably supported by a support member 16a installed on the separate plate 16, and are configured not to move in the thrust direction. On the other hand, the take-up roller 14 is rotatably supported by a support member 17 a installed on the carriage 17, and moves in the thrust direction when the carriage 17 is moved by the thrust adjustment motor 24. At this time, the bogie 17 is moved in a range in which the engagement between the gear 141b and the gear 141c is maintained.

In the case of such a configuration, since the rotation driving motor 23 does not move in the thrust direction and does not require members arranged in the thrust direction such as the bellows 32 and the holding member 34 in the seal portion 1B, the vacuum chamber 1A The size of the protruding portion can be suppressed.
In the example of the installation structure shown in FIG. 4, since the disk 14a is not installed at the end of the rotation shaft of the take-up roller 14, this portion can be used for different functions.
For example, in the example shown in FIG. 4, a rotary joint 14b is installed at the end of the rotation shaft of the winding roller 14, and the air for air chuck installed on the rotation shaft of the winding roller 14 via the rotary joint 14b. Supply routes.
In this case, by winding the laminated film, even if the amount of the laminated film accumulated in the winding roller 14 changes, the strength of the air chuck can be adjusted in accordance with the change, The winding roller 14 can be more appropriately held on the rotating shaft.
Further, also in the vacuum laminator 1 according to the first modification, it is possible to adopt a structure in which resistance (rotational friction) to the rotating shaft in the seal portion 1B is not generated.

The above-described embodiments and modified examples are examples of the embodiments of the present invention, and various embodiments for realizing the functions of the present invention are included in the scope of the present invention.
For example, in the first embodiment, the case where the present invention is applied to the take-up roller 14 has been described as an example, but the present invention is not limited to this. For example, the present invention can be applied to various rollers, such as the upper film roll shaft 11A or the lower film roll shaft 11B, which rotate when a driving force is input from outside the vacuum chamber 1A.

In the above-described embodiment and the modified example, the disk 14a is provided at the end of the rotation shaft of the winding roller 14, and the disk 23a is disposed at the end of the rotation shaft of the rotation driving motor 23 so as to face the disk 14a. And the configuration in which the disk 14a and the disk 23a are electromagnetically connected has been described as an example, but the present invention is not limited to this. That is, as a form of electromagnetically connecting the rotation shaft of the take-up roller 14 and the rotation shaft of the rotation drive motor 23, it is possible to adopt various structures using a device other than a disk. For example, one of the rotation shaft of the winding roller 14 and the rotation shaft of the rotation drive motor 23 is an inner cylinder, the other is an outer cylinder, and magnets are installed on the outer periphery of the inner cylinder and the inner periphery of the outer cylinder, respectively. May be electromagnetically connected to each other.

Further, in the above-described first modification, the description has been made assuming that the speed reduction mechanism 141 is installed on the rotation shaft of the winding roller 14, but the invention is not limited thereto. That is, in the configuration shown in FIG. 4, instead of the speed reduction mechanism 141, a gear mechanism having a gear ratio that does not perform speed reduction, a rotation transmission mechanism other than a gear such as a belt, or the speed reduction mechanism 141 is provided. Instead, the disk 14a can be directly installed at the tip of the rotating shaft of the winding roller 14.
Further, the above-described embodiment and modified examples can be appropriately combined to constitute the vacuum laminator 1. For example, the example of the installation structure shown in FIG. 3 and the example of the installation structure shown in FIG.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. Further, the effects described in the present embodiment merely enumerate the most preferable effects resulting from the present invention, and the effects according to the present invention are not limited to those described in the present embodiment.
