Description

Carrying device

The invention relates to a bearing device, and more particularly to a bearing device with an inclined bearing surface.

After the conventional optical film is packaged into a bearing device, in order to protect the bearing device, an aluminum foil is generally used to cover the bearing device and extract the air in the aluminum foil, so that the aluminum foil is close to the surface of the bearing device. However, such a packaging method will have more packaging steps (such as an aluminum foil coating step and a vacuum step, etc.) and will increase the cost of aluminum foil consumption.

The invention relates to a carrying device, which can improve the aforementioned problems.

According to an embodiment of the present invention, a supporting device for an optical film is provided. The carrying device includes a carrying portion and a side portion. The bearing portion has a bearing surface and a bottom surface. The bearing surface is located above the bottom surface and is used for carrying a plurality of optical films. The bearing surface has a first side and a second side which intersect at a first point, and the first side is The first point has a first inclination angle with the bottom mask, and the second side has a second inclination angle with the bottom mask at the first point. The side portion is connected to the bearing portion and is used to abut a first side surface of the optical films.

View, FIG. 1C is a schematic perspective view of the bearing portion 110 and the side portion 170 of the load bearing device 100 in FIG. 1A, and FIG. 1D is a schematic view of the first stopper 130 in FIG. 1A.

The carrying device 100 is used for receiving at least one optical film 10. The optical film 10 is, for example, a polarizing plate or other kinds of optical elements. The carrying device 100 includes a carrying portion 110, an upper cover 120, a first stopper 130, a second stopper 140, a seal 150, an exhaust valve 160, and a side portion 170. As shown in FIGS. 1A to 1C, the carrying portion 110 has a carrying surface 110 u and a bottom surface 110 b. The carrying surface 110 u is located above the bottom surface 110 b and is used to carry the optical film 10. The bearing surface 110u has a first side 110u1 and a second side 110u2 that intersect the first point P1. The first side 110u1 has a first inclination angle A1 at the first point P1 and the bottom surface 110b, and the second side 110u2 has a second inclination angle A2 at the first point P1 and the bottom surface 110b. Due to the design of the first inclination angle A1 and the second inclination angle A2, the optical film 10 placed on the bearing surface 110u is automatically tilted in the direction of the first point P1 by its own weight, which can save the additional movement and man-hours of manual movement. . In addition, since the optical film 10 above the inclined bearing surface 110u tends to move closer to the first point P1, there is no need to specifically bundle the optical film 10, which can save the process of bundling several optical films 10 with a packaging tape And packaging materials, and / or can also save materials such as the bottom plate carrying the optical film 10.

In one embodiment, the first inclination angle A1 and / or the second inclination angle A2 is an angle between 5 degrees and 30 degrees.

In addition, as shown in Figures 1A to 1C, the bearing surface 110u has The second side 110u3 and the fourth side 110u4 of the two points P2, wherein the third side 110u3 is opposite to the first side 110u1 and connects the second side 110u2 and the fourth side 110u4, and the fourth side 110u43 is opposite and connected to the second side 110u2 The first side 110u1 and the third side 110u3. In this embodiment, the bearing surface 110u is a rectangular bearing surface, and the first point P1 and the second point P2 are vertices of a pair of corners of the rectangular bearing surface. Due to the design of the first inclination angle A1 and the second inclination angle A2, the bearing surface 110u is inclined from the second point P2 toward the first point P1. In this way, when the optical film 10 is placed on any area on the bearing surface 110u, the optical film 10 can automatically tilt toward the first point P1 by its own weight.

As shown in FIGS. 1A to 1C, the side portion 170 includes a first support member 171a, a second support member 172b, a third support member 173, and a fourth support member 174 that are connected. The first support member 171a, the second support member 172a, the third support member 173, and the fourth support member 174 are connected to the bearing portion 110 and are each substantially perpendicular to the bottom surface 110b. The first support member 171a and the third support member 173 Opposite, and the second support 172a is opposite to the fourth support 174.

As shown in FIGS. 1A to 1C, the side portion 170 further includes a first stopper 171 b and a first support member 171 a. The first stopper 171b has a first contact surface 171s for contacting the first side surface 10s1 of the optical film 10. The first contact surface 171s is substantially perpendicular to the bearing surface 110u, such as between the first contact surface 171s and the bearing surface 110u. The angle A3 is approximately 90 degrees. In one embodiment, the shape of the first contact surface 171s may be a flat surface, a curved surface, or a wavy surface, which can reduce the contact area with the optical film 10 to avoid damaging the optical film 10. In addition, as shown in FIG. 1B, the side portion 170 further includes a second stopper 172b. Connected to the second support 172. Similarly, the second stopper 172b has a second contact surface 172s for contacting the second side surface 10s2 of the optical film 10, wherein the second contact surface 172s is substantially perpendicular to the bearing surface 110u. In this way, when the first side surface 10s1 and the second side surface 10s2 of the optical films 10 abut against the first contact surface 171s and the second contact surface 172s, respectively, the first side surface 10s1 and the bottom surface of the optical film 10 The corner formed by 10b can completely abut the first contact surface 171s and the bearing surface 110u, and the corner formed by the second side surface 10s2 and the bottom surface 10b of the optical film 10 can completely abut the second contact surface 172s and the bearing surface 110u. Avoid these corners from being deformed on the bearing surface 110u.

As shown in FIG. 1B, a clearance R1 is provided between the first stopper 171 b and the second stopper 172 b.
