First, as shown in Figures 3A(a) and 3A(b), Figure 3A(a) illustrates a schematic diagram of an optical film 10 surrounded by a surrounding member 110 according to an embodiment of the present invention, and Figure 3A(b) A top view of the optical film 10 and the surrounding member 110 in FIG. 3A(a) is shown. As shown in the figure, a plurality of optical films 10 are surrounded by a surrounding member 110, wherein the optical film 10 is, for example, a polarizing film, a reflective film, a diffusion film, a brightness enhancement film, or other types of single or multilayer optical films, etc. The present invention does not use this Is limited.

The surrounding member 110 in this embodiment is, for example, a belt, which can be, for example, a polyethylene terephthalate film (PET) coated with a release agent, or, for example, but not limited to a silicone release (SP) Film. In detail, in this step, the upper surface of the optical films 10 may be surrounded by a surrounding member 110a. The surface 10u, the first side surface 10s1, the lower surface 10b, and the second side surface 10s2, wherein the first side surface 10s1 and the second side surface 10s2 are opposite. Then, another surrounding member 110b surrounds the upper surface 10u, the third side surface 10s3, the lower surface 10b, and the fourth side surface 10s4 of the optical films 10, wherein the third side surface 10s3 and the fourth side surface 10s4 are opposite to each other, thereby wrapping These optical films 10 are bundled. In other words, these optical films 10 can be bound by two straps in a crisscross manner, as shown in Figure 3A(b), which can prevent these optical films 10 from spreading. In another embodiment, the optical film 10 may be surrounded and wrapped by one of the surrounding member 110a and the surrounding member 110b, and the present invention is not limited thereto.

Then, as shown in FIG. 3B, a carrier box 120 is provided. The carrying box 120 includes a bottom wall 121, a first side wall 122, a second side wall 123, a third side wall 124, and a fourth side wall 125. The first side wall 122, the second side wall 123, the third side wall 124 and the fourth side wall 125 are vertically oriented Ground or substantially perpendicularly connected to the bottom wall 121, wherein the first side wall 122 is opposite to the second side wall 123, and the third side wall 124 is opposite to the fourth side wall 125.

Then, as shown in Figures 3C(a) and 3C(b), Figure 3C(a) shows a schematic diagram of the optical film 10 of Figure 3A(a) placed in the carrier box 120, and Figure 3C(b) The figure shows a top view of the optical film 10 and the carrier box 120 of figure 3C(a). As shown in the figure, the optical films 10 bound by the surrounding member 110 are placed in the carrying box 120 and on the carrying surface 120u of the bottom wall 121 of the carrying box 120. In another embodiment, the carrier box 120 in Figure 3C(a) can be replaced by the carrier box 220 in Figure 7A(a) described later.

Then, as shown in the 3D diagram, place at least one buffer on the bearing The space between the carrier box 120 and the optical films 10 is used to fix the relative positions of the optical films 10 and the carrier box 120 to form a carrier device.

In one embodiment, a buffer 131 may be provided between one of the side surfaces (for example, the first side surface 10s1) of the optical films 10 and the side wall (for example, the first side wall 122) of the carrier box 120 corresponding to the side surface. Space, so that the buffer 131 can be used to resist the optical films 10 to fix the optical films 10 in the carrier box 120 and prevent the optical films 10 from going perpendicular to the side surface (for example, the x direction) Displacement. In one embodiment, the cushioning member can be made of materials with shock absorption effect, such as foamed cotton, sponge, plastic film, corrugated paper, cotton wool and other materials. Due to the vibration-absorbing properties of the cushioning member, if these optical films 10 are impacted by an external force, most of the impact force can be absorbed through the cushioning member, and the optical films 10 are prevented from being displaced too greatly in the carrier box 120 and hitting The side walls are damaged.

In this embodiment, another buffer member 132 may be disposed on another side surface (for example, the third side surface 10s3 or the fourth side surface 10s4) perpendicular to the aforementioned side surface (for example, the first side surface 10s1) of the optical films 10 The space between the corresponding side wall (for example: the third side wall 124 or the fourth side wall 125), so as to fix the optical films 10 in the carrier box 120 and prevent the optical films 10 from going perpendicular to this Displacement in the direction of the side (for example: y direction).

In another embodiment, four buffers 131, 132, 133, and 134 may be provided in the spaces between the four side surfaces of the optical film 10 and the four side walls of the carrier box 120, so that the buffers can be used. The members 131, 132, 133, and 134 resist the four sides of the optical film 10 and absorb impacts from four directions And prevent these optical films 10 from being displaced in various directions (for example, x direction and y direction). The buffer members 131, 132, 133, and 134 may be formed of the above-mentioned materials and may be the same or different from each other, and the present invention is not limited thereto. In this way, by providing at least one buffer, the relative positions of the optical films 10 in the carrier box 120 can be stabilized. When the number of buffers is multiple, these buffers are arranged separately. However, the number of buffer members located between the same side surface of the optical films 10 and the side wall of the carrier box 120 corresponding to this side surface is not limited to one, and may also exceed one (for example, buffer members 131 and 134).

Then, as shown in FIG. 3E, a covering member 140 is arranged above these optical films 10. The cover 140 can be docked with the carrier box 120 to protect or completely seal the optical film 10, the surrounding member 110 and the buffer members (such as the buffer members 131 to 134) between the cover 140 and the carrier box 120. In this embodiment, the structure of the cover 140 may be similar to the carrier box 120 or the same as the carrier box 120 to save the design and/or manufacturing cost of the cover 140. In another embodiment, the covering member 140 may be a flat plate, which only covers the upper surface 10 u of the optical films 10. In another embodiment, when the carrier box 120 in Figure 3C(a) is replaced with the carrier box 220 in Figure 7A(a), the cover 140 in Figure 3E can be replaced with the cover 240 described later.

Then, a second wrapping bag 150 (such as the element 150 shown in Figures 3G and 3H) is used to cover the surrounding member 110, the carrier box 120, the optical films 10, and the covering member 140; then, the second wrapping bag 150 is drawn out The air makes the second wrapping bag 150 in a vacuum state, which can isolate the outside air to prevent pollution.

In an embodiment, a second wrapping bag 150 may also be provided to directly pack the packaging structure 100'.

Then, as shown in Figure 3H, a vacuum source (not shown) can be used to extract the air in the second wrapping bag 150 through the opening 150a, so that the second wrapping bag 150 is deformed and can be closely attached to the carrier box 120 and The cover 140 reduces the volume of the second wrapping bag 150. As shown in Figure 3H, at least a part of all the outer surfaces of the packaging structure 100' are tightly attached by the second wrapping bag 150, so that the volume of the packaging structure 100" in Figure 3H is smaller than that of the packaging structure 100' in Figure 3E. .

Then, as shown in Figure 3H, the opening 150a of Figure 3G is closed to maintain the vacuum state in the second wrapping bag 150.

Then, as shown in FIG. 3I, place at least one packaging structure 100" as shown in FIG. 3H in the packaging box 160 to form a carrying device, such as the packaging box 100.

In this embodiment, the packaging structure 100' in Figure 3I can be placed in the packaging box 160 in a manner that the thickness direction (such as the z direction) is perpendicular to the ground.

However, the embodiment of the present invention does not limit the orientation in which the packaging structure 100" in Figure 3I is placed in the packaging box 160. For example, as shown in Figure 4, it shows The packaging structure 100" in Figure 3I is placed in the packaging box 160 in different orientations. The packaging structure 100" in Figure 3I can be placed in the packaging box with the thickness direction (such as the z direction) parallel to the ground. Within 160. In this placement mode, as shown in FIG. 4, the supporting surface 120u of the supporting box 120 is substantially perpendicular to the bottom surface 160b of the packaging box 160.

Since the buffer (for example: 131~134) can stabilize the position of several optical films 10 in the carrier box 120, the packaging structure 100" can be placed in the packaging box 160 in any orientation. In addition, because of the buffer (for example: 131) ~134) has vibration absorption characteristics, so even if the packaging structure 100" is impacted (such as dropped or hit), it will not damage the optical film 10 in the packaging structure 100".

FIG. 5 shows a packaging process diagram of an optical film 10 according to another embodiment of the present invention. As shown in the figure, the surrounding member 110' surrounds several optical films 10. The surrounding member 110' of this embodiment is the first wrapping bag, which has an opening 110c. The optical film 10 can enter the surrounding member 110' through the opening 110c, and then stick the opening 110c with an adhesive tape to prevent the optical film 10 from falling out of the surrounding member 110'. In an embodiment, the first wrapping bag may be a plastic bag, and its material may include polyethylene terephthalate, polyethylene or other materials. Alternatively, the surrounding member 110' can also be a single film, and its material can be similar to the aforementioned plastic bag. The remaining steps of forming the packaging box 100 in this embodiment can adopt the corresponding steps similar to the above-mentioned 3A(a) to 3I, and will not be repeated here.

As shown in the figure, the first side wall 122 and the second The side wall 123, the third side wall 124 and the fourth side wall 125 are continuously connected to form four corners R1. Four buffer members 131 to 134 are placed between each corner R1 of the carrier box 120 and the two sides of the optical film 10 corresponding to the corners. Then, the optical films 10 surrounded by the surrounding member 110 are placed in the carrier box 120, and the buffer members (for example, 131 to 134) are located between the optical film 10 and the corner R1 of the carrier box 120. With the packaging method of this embodiment, each of the buffer members 131 to 134 can resist the two sides of the optical film 10, so that the optical film 10 can be absorbed in four directions, and the optical film can be prevented. 10 Displacement in all directions in the carrying box 120 causes it to hit the side wall and be damaged.

In this embodiment, each cushioning member (for example: 131 to 134) may also have a concave portion 130a, and the position of each concave portion 130a is located at the junction of the two side surfaces corresponding to the corners of the optical film 10, thereby avoiding the cushioning member 131 ~134 crushes the corner C1 of the optical film 10 or deforms the corner C1 of the optical film 10. In addition, the remaining steps of forming the packaging box 100 in this embodiment can adopt the corresponding steps similar to the above-mentioned 3A(a) to 3I, which will not be repeated here.

Please refer to FIGS. 9A to 9C. FIG. 9A shows a schematic diagram of a packaging structure 200' according to another embodiment of the present invention, and FIG. 9B shows a view from the inside of the packaging structure 200' of FIG. 9A toward the optical film 10 Fig. 9C shows a top view of the partition 210c between Fig. 9B.

The packaging structure 200' includes a plurality of optical films 10, surrounding members 110a and 110b, at least one spacer 210, a carrying box 220, a bottom plate 305, and a top plate 306. The bottom plate 305 is disposed on the bottom wall 221 of the carrying box 220 and carries the optical films 10. The top plate 306 is disposed on the top of these optical films 10 to protect the optical film 10 at the uppermost layer. In another embodiment, the top plate 306 can be replaced by a spacer plate 210. The material of the top plate 306 can be similar to that of the bottom plate 305, which will not be repeated here. In this embodiment, the optical film 10 includes four sides, but the present invention is not limited to this. In other embodiments, the optical film 10 may include at least or more than three sides, or be connected by a straight line and at least one arc. Become.

The spacer 210 can be arranged below at least one of the optical films 10, so that when the spacer 210 is lifted, the optical film 10 located above it is also lifted. The number of spacers 210 can be multiple, as shown in Figure 9A, the number of The partitions 210 (ie, the partition plates 210a, 210b, and 210c) are respectively disposed between the optical films 10, and the bottom plate 305, the top plate 306, all the optical films 10, and the partition plate 210 are bundled into one body through the surrounding members 110a and 110b . Thereby, when one of the spacer plates 210 is lifted, all the optical films 10 are also lifted. As shown in FIGS. 9A and 9B, the number of spacers 210 in this embodiment is illustrated by taking three as an example, such as spacers 210a, 210b, and 210c. However, in the embodiment of the present invention, the number of spacers 210 is not determined. As shown in the figure, the spacers 210a to 210c are respectively arranged between the optical films 10. In one embodiment, each spacer 210 can be arranged between a certain number of optical films 10. For example, every certain number (such as 50 pieces, or less or more) of optical films 10 is separated from other optical films 10 by a spacer 210. In other embodiments, the number of spacers 210 is at least one, which can be adjusted according to actual needs or the number of optical films 10.

According to the embodiment of the present invention, the operator can first cut the surrounding members 110a and 110b, and lift up one of the spacers 210 to take out a predetermined number of optical films 10, instead of removing the entire bundle of optical films 10 from the carrier box 220 at a time. Take it out and calculate the quantity to take. For example, as shown in Figure 9A, after cutting the surrounding members 110a and 110b, to take out 50 optical films 10 from the carrier box, the operator can lift the spacer plate 210c and hold the spacer plate 210c on it. Take out the optical film 10 together; if you want to take out 100 optical films 10 from the carrier box, the operator can take out the optical film 10 on it by lifting the spacer 210b and holding the spacer 210b, and so on . Thereby, the time for taking the optical film 10 can be effectively saved and the possibility of damage to the optical film 10 can be reduced.

In addition, as shown in FIG. 9A, the spacer 210 is not arranged under the lowermost optical film 10, but in another embodiment, the spacer 210 may also be arranged. In other embodiments, the number of spacers 210 may be one, which may be disposed at the bottom of all optical films 10 or inserted between these optical films 10, but the embodiment of the present invention is not limited thereto.

As shown in FIG. 9C, the partition plate 210 includes a plate body 211 and a first protrusion 212. In one embodiment, the shape of the plate body 211 may be rectangular, but the invention is not limited to this. The board 211 has a first side 211s1 and a third side 211s3 opposite to each other, and a second side 211s2 and a fourth side 211s4 opposite to each other. The first protrusion 212 is connected to the board 211 and protrudes from one side (such as the first side 211s1), and protrudes beyond the side of the optical film 10 (such as the fourth side 10s4), as shown in Figures 9A and 9B . In this way, the first protrusion 212 protruding from the optical film 10 can be easily grasped by the operator, so as to facilitate the picking and placing of these optical films 10.

In an embodiment, the plate body 211 and the first protrusion 212 may be formed into an integral structure in the same manufacturing process. The aforementioned manufacturing process is, for example, stamping or cutting. In another embodiment, the plate body 211 and the first protrusion 212 may be formed separately and then connected to the spacer plate 210 by any connection method. The aforementioned connection method is, for example, bonding. In an embodiment, the material of the plate body 211 and the first protrusion 212 may be the same or different. The material of the board body 211 and the first protrusion 212 can be made of polypropylene (PP), polystyrene (PS), cardboard, corrugated paper, cardboard or acrylic.

In this embodiment, as shown in FIG. 9C, the first protrusion 212 is a polygon, such as a quadrilateral. As shown, the first protrusion 212 is from the optical film The protruding part of 10 (dotted line area) has a first side length L1 and a second side length L2. The first side length L1 may be between 25 mm and 35 mm, that is, the protruding length of the first protrusion relative to the side surface of the optical film 10 (such as the fourth side surface 10s4) is between 25 mm and 35 mm. In addition, the second side length L2 can also be between 25 mm and 35 mm, but the embodiment of the present invention is not limited thereto.

In an embodiment, the protruding position of the first protrusion 212 of each spacer 210 on the plate body 211 can be configured with the bottom plate 305 and the surrounding member 110b. As shown in FIGS. 8A and 9B, the bottom plate 305 has two opposite first notches 305r1 and two opposite second notches 305r2. The surrounding member 110a surrounds the bottom plate 305, the top plate 306, the optical film 10 and the plate body 211 of the spacer 210 through the two first notches 305r1 of the bottom plate 305, and the surrounding member 110b surrounds the bottom plate 305 and the top plate 306 through the two second notches 305r2 of the bottom plate 305 , The optical film 10 and the plate body 211 of the spacer 210, and avoid the first protrusion 212 of each spacer 210. In other words, all the first protrusions 212 and the surrounding member 110b do not overlap. Since the surrounding member avoids the first protrusion 212 (thereby preventing the first protrusion 212 from being compressed and deformed by the surrounding member), the protruding shape of the first protrusion 212 can be maintained to facilitate the operator to grasp the complete first protrusion 212. In another embodiment, the first protrusion 212 can avoid the surrounding member, and the first protrusion 212 is not limited to protrude the first side 211s1.

As shown in FIGS. 9B and 9C, the area of each optical film 10 may be equal to or larger than the area of the plate body 211 and cover the entire plate body 211. In this way, it is possible to prevent the surrounding members 110a and 110b from being interfered by the plate body 211, and to closely adhere to the optical film 10, thereby more stabilizing the relative position of the optical film 10.

In this embodiment, the first protrusions 212 of the spacers 210 do not overlap with each other. For example, as shown in FIG. 9B, the first protrusions 212 of the spacers 210 are staggered from each other along a direction (such as the x direction) perpendicular to the stacking direction of the optical films 10 (such as the z direction). This can prevent the operator from being interfered by other first protrusions 212 when grabbing one of the first protrusions 212.

As shown in FIG. 9A, the end of the first protrusion 212 of the spacer 210 faces the fourth side wall 225 of the carrier box 220. In an embodiment, the first distance D1 between the end of the first protrusion 212 of each spacer 210 and the fourth side wall 225 may be the same or different, and the embodiment of the present invention is not limited thereto. In this embodiment, the first distance D1 between the end of the first protrusion 212 of each spacer 210 and the fourth side wall 225 is different. For example, the lengths of the first protrusions 212 of the partition plates 210 are different, and the partition plates 210 are arranged in such a way that their first protrusions 212 are gradually shorter from the bottom wall 221 upwards, so that the first distances D1 are from The upward direction of the bottom wall 221 becomes longer. In this way, the upper first distance D1 is longer than the lower first distance D1, so that when the operator grasps the first protrusion 212 from top to bottom, the operator is interfered by a smaller or least number of first protrusions 212. In another embodiment, based on different considerations, the first distances D1 can be gradually shorter from the bottom wall 211 upward; or, the first distances D1 can also be changed arbitrarily, and are not limited to being shorter or longer. . In addition, the smaller the size of the optical film 10, the longer the first distance D1 can be. For example, when the size of the optical film 10 is 15.6 inches, the length of the long side of the optical film is about 350 mm, and the first distance D1 is, for example, between about 15 mm and about 25 mm; when the size of the optical film 10 When it is a smaller 14 inches, the length of the long side of the optical film is about If it is 315 mm, the first distance D1 can be increased to, for example, between about 50 mm and about 60 mm.

As shown in FIG. 9A, there is a second distance D2 between the optical film 10 and the fourth side wall 225. The ratio of the aforementioned first distance D1 to the second distance D2 is between 0.3 and 0.5. In this way, it is possible to prevent the first protrusion 212 from being too close to the fourth side wall 225, thereby avoiding excessive interference in the process of the operator grasping the first protrusion 212.
