Description

Laminating device with shielding member

The present invention relates to the manufacture of an optical display unit, and more specifically, to a lamination device provided with a shielding member, which is also capable of changing the conveying direction of the optical film by using an air turn bar. The optical film bonding device installed in a narrow space can reduce the adverse effects of the air from the pneumatic rotating rod on the optical film or panel components.

In recent years, in the manufacturing site of optical display units, there has been a roll-to-panel method (hereinafter referred to as RTP method) manufacturing device instead of cutting out with other equipment in advance. A single-piece manufacturing device in which a sheet-like optical film laminate is carried in and bonded to a panel member. In the RTP method manufacturing device, a ribbon-shaped optical film laminate is drawn out, and a cutting line is embedded in the derived ribbon-shaped optical film laminate in the device to form a sheet-shaped optical film, and The sheet-shaped optical film can be peeled from a carrier film and can be continuously bonded to the panel member.

As such an RTP manufacturing device, a linear device is often used in the past. Linear manufacturing equipment refers to the conveying path of the panel member, the supply part of the optical film attached to both sides of the panel member, the conveying path of the optical film, the forming part of the cutting line, the bonding of the panel member and the optical film sheet Parts etc. are arranged in a linear device. In the linear device, when the single-chip manufacturing device used before the RTP method is replaced with the RTP method manufacturing device, a problem of installation space limitation occurs.

The applicant of this application aims to cope with this problem, and proposes a compact RTP manufacturing device (hereinafter referred to as compact) that reduces the overall length and width of the device and can also be installed in a narrow space. RTP device) (Patent Document 1). In a small RTP device, a part of the conveying path of two optical films laminated on both sides of the panel member is constructed so that a part of the conveying path overlaps vertically, and a pneumatic rotary rod can be arranged in the middle of the film conveying path. Pneumatic rotating rod refers to a device that floats the optical film while changing its direction by the pressure of the air ejected from the outer peripheral surface.

When a pneumatic rotating rod is used, the air ejected from the outer peripheral surface of the pneumatic rotating rod flows out between the pneumatic rotating rod and the optical film that changes the conveying direction. The air flowing from between the outer peripheral surface and the optical film on both ends of the pneumatic rotating rod will disturb the air flow in the laminating device. When the air flow is disturbed, there is a fear that the outflowing air will directly touch the conveying line of the panel member, or foreign matter may adhere to the panel member or optical film being transported, or the foreign matter in the laminating device may be rolled up and The rolled foreign matter may indirectly adhere to the panel member or the optical film through constituent parts such as a conveyor of the conveying line.

Fig. 2 is a schematic diagram showing the structure and arrangement of the shielding member 5 and the air flow generating portion 6 according to an embodiment of the present invention; Fig. 2(a) is a plan view of the part where the shielding member 5 and the air flow generating portion 6 can be installed , Figure 2(b) is a front view of the part (a) in Figure 2 viewed from the downstream side of the conveying direction of the panel member W, and Figure 2(c) is the part (a) in Figure 2 Side view. The shielding member 5 and the air flow generating part 6 shown in FIG. 2 control the flow of air flowing from between the outer peripheral surface of the pneumatic rotating rod 33 and the optical film laminate L2. Furthermore, in (a) of FIG. 2, the upper surface (top plate) of the frame 7 is not shown. In addition, in (b) in FIG. 2 and (c) in FIG. 2, in order not to make the drawings complicated, the components located below the panel member conveying portion 14 are not shown.

The shielding member 5 is arranged between the pneumatic rotating rod 33 and the panel member conveying part 14 located below the pneumatic rotating rod 33, and is used for shielding to prevent the outflow of air from the pneumatic rotating rod 33 from reaching the panel member conveying part 14 On the component.

The distance at the rearmost end in the conveying direction is still long. The position in the height direction at which the shielding member 5 can be arranged is provided as long as a space that can be accessed in the panel member W located on the panel member conveying portion 14 during maintenance work is secured, for example, Preferably, it is as close as possible to the position of the panel member conveying part 14. Furthermore, the thickness of the shielding member 5 is not particularly limited.

The material of the shielding member 5 is not particularly limited, and lightweight metals such as aluminum can be used. In addition, the method of fixing the shielding member 5 in an appropriate position is not particularly limited as long as it does not hinder the flow of the downward airflow described later, or affect the conveyance of the panel member W and the optical film laminates L1 and L2. For example, it can be installed in a frame supporting the panel member conveying part 14, or installed in the panel member conveying part 14, or a plurality of supporting members installed so as to protrude upward from the floor, or from the frame The top plate of 7 is suspended to fix.

The air flow generating part 6 is capable of generating a downward air flow from the top plate of the frame body 7 toward the lower side, and preferably includes an air suction means for a filter that makes the air supplied into the laminating device 1 clean air. Although the filter is preferably a HEPA (High Efficiency Particulate Air) filter, it is not limited to this. As a suction means equipped with a HEPA filter, a commercially available HEPA filter unit well known to those skilled in the art can be used. The air flow generating part 6 may also be an air blowing means that sucks the air in the laminating device and sends it to the bottom.

As shown in FIG. 2, the air flow generating part 6 is preferably installed above both ends of the panel member conveying part 14 in the width direction. By installing the airflow generating part 6 at this position, as described later, the outflow air from the pneumatic rotating rod 33 can pass through the shielding member 5 and the panel member conveying part 14 together with the downflow from the airflow generating part 6 It is controlled by the way that it flows downward between the two ends in the width direction and the frame 7.

The flow rate of the airflow generated by the airflow generating unit 6 can be controlled in such a way that the outflowing air from the pneumatic rotating rod 33 passes between the shielding member 5 and the panel member conveying unit 14 and the frame 7 and flows downward. It is not specifically limited, but can be set to, for example, 20 m ³ /min to 35 m ³ /min.

Fig. 3 is a schematic diagram showing the flow of air in the part corresponding to Fig. 2 with arrows. Fig. 3(a) is a front view of the flow of air without the shielding member 5 and the air flow generating portion 6 of the present invention viewed from the downstream side of the conveying direction of the panel member W, and Fig. 3(b) is Its side view. Fig. 3(c) is a front view of the air flow when the shielding member 5 and the air flow generating portion 6 are seen from the downstream side in the conveying direction of the panel member W, and Fig. 3(d) is a side view . The flow of air shown by the arrow in FIG. 3 is that a mist generating device (not shown) is arranged near the HEPA filter unit 9 or the air flow generating part 6, and the generated mist is passed through the HEPA filter unit 9 or the air flow generating part 6 is introduced into the frame 7 and the flow of mist in the frame 7 is visually confirmed. As the mist generating device, commercially available devices known to those skilled in the art can be used.

As shown in Figure 3(a) and Figure 3(b), in the conventional laminating device, a HEPA filter unit 9 is installed in the center of the top plate of the frame 7, and the pneumatic rotary rod There is no arrangement between 33 and the panel member conveying part 14. In this way, without the shielding member 5 and the air flow generating part 6 of the present invention, part of the outflow air from the pneumatic rotating rod 33 flows below the pneumatic rotating rod 33, and sometimes reaches the panel member conveying part 14 Above. When a foreign matter is contained in the air that has reached the panel member conveying section 14, the foreign matter may be directly attached to the panel member W being conveyed, or may be attached to the panel through components such as a conveyor of the panel member conveying section 14 Component W is concerned. In addition, the air from the HEPA filter unit 9 or a part of the outflow air from the pneumatic rotating rod 33 may disturb the laminating device 1 even if it does not directly reach the panel member conveying portion 14.

On the other hand, as shown in Fig. 3(c) and Fig. 3(d), when the shielding member 5 and the air flow generating part 6 are used, the outflow air from the pneumatic rotating rod 33 is in contact with The upper surface of the shielding member 50 flows toward the outer side of the shielding member 5. On the other hand, the air sucked into the frame 7 from the airflow generating part 6 installed above the widthwise ends of the panel member conveying part 14 is conveyed by the pneumatic rotating rod 33, the shielding member 5, and the panel member Each of the width direction ends of the parts 14 flows downward between the frame body 7 and exhausts air from, for example, below the frame body 7 or an exhaust part installed on the floor. In this process, the descending airflow from the airflow generating part 6 is the outflow air that hits the upper surface of the shielding member 5 and flows outward while being caught, and the outflow air that flows upward from the pneumatic rotating rod 33. And one side flows downward. Therefore, the outflowing air from the pneumatic rotating rod 33 does not disturb the air flow in the laminating device 1 to cause the wind of foreign matter, and does not reach the panel member conveying portion 14. In addition, the shielding member 5 can also prevent foreign matter from the pneumatic rotating rod 33 from falling on the panel member conveying portion 14.
