Symbolic representation.

The various features of the invention are set forth in the description of the various embodiments of the invention. Of course, these are only examples and should not limit the scope of the invention.

Please refer to FIG. 1 , which illustrates an automatic take-up machine 100 and related equipment and sheet 200 according to an embodiment of the invention. The automatic film receiver 100 is disposed, for example, across a platform 300, as shown in Fig. 1, but is not limited thereto. The sheets 200 are arranged in a plurality of rows, including a row of sheets 200-1 to be picked up by the automatic take-up machine 100, a next row of sheets 200-2 adjacent thereto, and the like, each row including at least one sheet 200 , configured on the platform 300. The sheet 200 may be, for example, a polarizing plate. In an embodiment, it may be a small and medium size polarizing plate.

The automatic take-up machine 100 includes a take-up module 110 and a tablet lever 120. The film collection module 110 includes a take-up lever 112 and a ejection lever 114. The take-up lever 112 can be moved up and down to pick up a sheet of material 200-1. In an embodiment, the take-up bar 112 picks up only one sheet 200-1 at a time. In another embodiment, the take-up bar 112 can be used to simultaneously pick up a plurality of sheets 200-1 arranged in a row. In an embodiment, as shown in FIG. 1, the take-up lever 112 may include a telescopic member 116 disposed above for taking up and down movement of the take-up lever 112. The telescopic member 116 is, for example, a spring. However, the take-up lever 112 can also be moved up and down by other mechanisms, and is not limited to the use of the telescopic member 116. In an embodiment, the telescoping member 116 can be a suspension element or a suspension system. The eject lever 114 cooperates with the take-up lever 112 to retract the picked-up sheet 200-1. The tableting lever 120 is for fixing the next sheet adjacent to the sheet 200-1 when the sheet 200-1 is picked up 200-2.

The automatic take-up machine 100 can also include a support arm 130 for supporting the take-up module 110 and the tablet lever 120. In an embodiment, as shown in FIG. 1 , the support arm 130 and the tablet lever 120 can be respectively disposed on two sides of the film collection module 110 . According to an embodiment, the support arm 130 can be moved and/or rotated to drive the overall movement and/or rotation of the automatic take-up machine 100; however, the position of the automatic take-up machine 100 can also be fixed, but by the platform 300 and The storage case for storing the sheet 200 is moved and/or rotated.

In an embodiment, the automatic take-up machine 100 may further include a viscous material 140, which is then disposed under the take-up bar 112 for adhering the sheet 200-1. A typical viscous material 140, as shown in FIG. 2, includes a substrate 142 and an adhesive layer 144, and typically also includes a release film 146. Of course, the adhesive material 140 is not limited to those shown in FIG. 2 . For example, the adhesive material 140 may further include an optical adhesive (OCA) layer and a second substrate (all of which are not drawn). Shown), arranged under the substrate 142 in order to achieve better seismic performance. In one embodiment, the optical adhesive layer may have a thickness of from 100 micrometers to 1000 micrometers, or may be from 100 micrometers to 600 micrometers, or may be from 100 micrometers to 400 micrometers.

Substrate 142 provides a supporting force. According to an embodiment, the substrate 142 may be made of polyethylene terephthalate (PET) or other hard substrate. According to an embodiment, the substrate 142 may have a thickness of from 50 micrometers to 500 micrometers, preferably from 70 micrometers to 300 micrometers. In one embodiment, when the adhesive 140 is used in conjunction with the automatic take-up machine 100, the substrate 142 is next to one of the take-up bars 112. If the thickness of the substrate 142 is too thin, so that the supporting force provided is insufficient, the adhesive material 140 may be lacking in a good flatness when it is next to the take-up bar 112, thereby causing the automatic film take-up machine 100. The effect of picking up the sheet 200 is not good.

The adhesive layer 144 is disposed on the other side of the substrate 142 (ie, the side that does not contact the take-up bar 112). According to an embodiment, the adhesive layer 144 may be a silicone pressure-sensitive adhesive layer and may have a steel plate adhesion force of 0.001 N/25 mm to 5.0 N/25 mm, preferably 0.02 N/25 mm to 0.80 N/25 mm. If the adhesion is insufficient, the sheet 200 may not be smoothly adhered, and even if the sheet 200 is successfully adhered, the sheet 200 may fall during the movement to the storage case. If the adhesion is too strong, it will cause the ejection is not easy. Both situations can result in interruptions in continuous processes.

The release film 146 can be disposed on the adhesive layer 144 to provide convenience in storage of the adhesive 140. When the viscous material 140 is followed by the take-up lever 112 and the pickup of the sheet 200 is to be started, the release film 146 is peeled off.

Although in this embodiment, the automatic take-up machine 100 is used in conjunction with the adhesive 140, other pick-up methods, such as a vacuum nozzle 150 (shown in FIG. 5) may be employed, which is followed by the take-up bar 112. Below, it is used to suck the sheet 200-1.

Referring now to Figures 3A-3G, an automatic film collection method in accordance with an embodiment of the present invention is illustrated. As shown in FIG. 3A, this method uses the automatic take-up machine 100 according to an embodiment of the present invention to move the sheet 200 placed on the platform 300 to the storage case 400 by the automatic take-up machine 100.

Referring to FIG. 3B, when the automatic take-up machine 100 is moved to a predetermined position (or the sheet 200 can also be driven by the platform 300 to a predetermined position), the tablet lever 120 is lowered to fix the tablet lever 120 adjacent to the desired pickup. The next piece of sheet material 200-1 is 200-2. Next, as shown in FIG. 3C, the take-up lever 112 of the film collection module 110 is lowered to pick up the sheet 200-1. Further, as shown in Fig. 3D, the take-up lever 112 is raised. At this time, since the lower sheet 200-2 is pressed by the tableting rod 120, even if there is still some connection force between the cut two sheets 200-1, 200-2, the next sheet 200-2 is also It does not come up with the sheet 200-1 to be picked up. Referring to FIG. 3E, after the take-up lever 112 is raised, the tablet lever 120 is raised. Thus, the pickup of the sheet 200-1 to be picked up is completed.

The picked up sheet 200-1 can then be moved to the storage case 400. When the sheet 200-1 is moved to an appropriate position, the sheet can be ejected as shown in Fig. 3F. The action taken continues to raise the take-up bar 112 such that the take-up bar 112 is more concave than the eject lever 114 to cause the picked-up sheet 200-1 to contact the eject lever 114 and separate from the take-up bar 112. As a result, the picked-up sheet 200-1 can fall into the storage case 400 as shown in FIG. 3G.

Next, the automatic take-up machine 100 can repeat the operations shown in FIGS. 3A to 3G, and successively move the next sheet 200-2 and the next sheet 200-3 to the storage box 400.

So far, a preliminary introduction has been made to the automatic film take-up machine and the automatic film collecting method according to the embodiment of the present invention. In order to provide a further understanding of the automatic film take-up machine and the automatic film collecting method according to the embodiment of the present invention, several examples and comparative examples will be described below.

[Example 1]

According to the automatic film take-up machine according to the embodiment of the present invention, the polarizing plate is collected in accordance with the use of the adhesive material as described in FIG. 2, the success rate of the film is counted, and whether the polarizing plate is defective due to the film is observed. . In this example, the viscous material package The PET substrate and the silicone pressure-sensitive adhesive layer were tested and tested for viscosity by a steel plate test method. Before testing the steel plate, first clean the test steel plate (304 or 302 stainless steel) with a damp cloth dampened with alcohol, let stand for about 5 minutes to dry the surface, and then take three pieces of viscous material test piece (length 30 cm, width) 2.5 cm), peel off the release film and attach it to the steel plate, and use a two-kilometer roller (width 45mm, diameter 83mm, weight 2000±50g) to roll back and forth, so that it is tightly attached to the steel plate without generating bubbles. After standing for 20 minutes under normal temperature, the speed of the tensile machine was set at 300 mm/min, and the steel plate was tested according to the JIS Z0237 specification.

[Example 2]

According to the automatic film take-up machine according to the embodiment of the present invention, in combination with the use of the vacuum nozzle, the polarizing plate is taken up, the success rate of the film is counted, and whether the polarizing plate is defective due to the film is observed.

[Comparative Example 1]

According to the automatic film take-up machine according to the embodiment of the present invention, the polarizing plate is taken up in conjunction with the use of an adhesive soft rubber pad, and the success rate of the film is counted and the polarizing plate is observed to cause defects due to the film. Further, the viscosity of the soft rubber pad was tested by the steel plate test method as described in Example 1.

[Comparative Example 2]

The polarizing plate is collected by manual operation, the success rate of the film is counted, and whether the polarizing plate is defective due to the film is observed.

[Results and discussion]

The test results of the examples and comparative examples are shown in Table 1.

According to Table 1, both Examples 1 and 2 have a good filming effect and can be continuously and stably operated. The soft rubber mat of Comparative Example 1 lacked sufficient supporting force, and compared with Example 1, it was relatively time consuming to follow the automatic take-up machine, and good flatness could not be obtained. Poor flatness leads to uneven distribution of adhesion, some of the polarizers fall off due to insufficient adhesion, and some polarizers are caused by too strong adhesion, causing the surface protective film to be picked up and generating bubbles. In Comparative Example 2, due to the manual operation, if the success rate of the film is to be ensured, the filming rate is extremely slow. In addition, it is easy to cause additional human damage, which increases the appearance defects of the polarizing plate.

Furthermore, although both Examples 1 and 2 have good filming effects, the use of vacuum nozzles requires additional space and cost. In addition, as in the case of the example 1 using a long strip of adhesive material, regardless of the cut one row including several sheets, all of the sheets can be picked up at once, as shown in the partial cross-sectional schematic view of the wafer module 110 of FIG. Show. If the vacuum nozzle 150 is used as in the example 2, the number of the vacuum nozzles 150 must be adjusted in accordance with the number of sheets per row, as shown in the partial cross-sectional view of the film collection module 110 of Fig. 5. Therefore, in contrast, the use of adhesive materials is more advantageous.

In summary, the present invention provides an automatic film collecting machine and an automatic film collecting method thereof, which can replace the manual manual work, can completely automate the overall process, and greatly improve the overall speed of the process. The automatic film take-up machine and the automatic film collecting method using the same according to the present invention are particularly suitable for small and medium-sized sheets, such as polarizing plates.

While the invention has been described above in the preferred embodiments, it is not intended to limit the invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
