The present invention relates to a technical field of liquid crystal display, and more particularly, to a packaging device for liquid crystal glass.
DESCRIPTION OF PRIOR ARTThe glass substrate used in the liquid crystal display panel is fragile and vulnerable to be broken if excessive external impact or vibration are encountered during the handling and transportation. Accordingly, in order to properly and thoroughly protect the glass substrate during the transportation or transfer from one station to another, the glass substrate has to be disposed within a specially designed and manufactured packaging device.
In general, the material used to make the packaging device is featured with excellent cushioning capability, while still with a certain stiffness so as to support the glass substrate. The EPP (Expanded Polypropylene), EPE (polypropylene foam), and EPS (Expanded Polystyrene Foam) are polymers with excellent shock-absorbing capability, but they are quite expensive as well.
As the dimensions of the glass substrate become larger and larger, the size of the packaging device has to grow larger so as to meet the requirements. Once the glass substrate becomes larger, its overall weight become heavier as well, and its own weight will create a warpage near to its center. However, the warpage of the glass substrate will make it more vulnerable to be broken. Accordingly, in order to counter the warpage resulted from the weight of the glass substrate, the packaging device has to increase it thickness. Nevertheless, the increasing of the thickness of the packaging device will not only increase the cost, but also will increase the bulky dimensions of the packaging device.

The plurality of sidewalks are interconnected with one another and extending from peripheral edges of the bottom walls so as to prevent any transversal movement of the liquid crystal glass; wherein the bottom wall is made from any one of the polyethylene foam, polypropylene foam, and high density polyethylene. Wherein the bottom wall has a superior cushioning capability than the reinforcing arrangement; and wherein the bottom wall is used to support the liquid crystal glass, and the reinforcing arrangement being disposed onto or in the bottom wall so as to prevent warpage of the bottom wall.
Wherein the reinforcing arrangement is integrally formed with the bottom wall.
Wherein the reinforcing arrangement is attached to the bottom wall after the bottom wall is formed through injection.
Wherein the reinforcing arrangement includes at least a pair of reinforcing ribs in parallel with each other.
Wherein the reinforcing arrangement includes a pair of reinforcing ribs intersecting with each other.
Wherein the reinforcing arrangement is completely embedded within the bottom wall or partially exposed from the bottom wall.
Wherein the reinforcing arrangement is made from metallic material or ceramic material.
Wherein the sidewalls and the bottom wall are made from same material integrally formed together.

Referring to
The supporting base 10 includes a bottom wall 11 and a plurality of sidewalls 12 interconnected with one another, and extending from peripheral edges of the bottom wall 11. The sidewalls 12 are used to prevent transversal movement of a glass substrate once it is carried on the supporting base 10.
According to its normal field application, as the glass substrate has a rectangular configuration, the bottom wall 11 of the supporting base 10 is also configured with a rectangular shape. The supporting base 10 has a pair of sidewalls 12.
The bottom 11 includes an inner surface (upper surface facing upward, and not labeled), and a bottom surface (not labeled). Substantial configuration of the bottom wall 11 should not be limited. For example, the bottom wall 11 can be defined with a plurality of channels extending from the inner surface to the bottom surface, or alternatively, the inner surface or the bottom surface can be provided with a plurality of embossments or slots.
Preferably, the supporting base 10, the bottom wall 11 and the sidewalls 12 are all made from the same material and preferably integrally formed. In order to ensure the glass substrate can be well cushioned on the supporting base 10, it preferably to have the supporting base 10 been made from material having excellent cushioning capability. For example, the supporting base 10 is made from any one of the polyethylene foam, polypropylene foam, and high-density polyethylene.
The reinforcing arrangement 20 is at least incorporated onto the bottom wall 11 of the supporting base 10 so as to prevent the bottom wall 11 from warping. Referring to
In order to prevent the bottom wall 11 of the supporting base 10 from warping, preferably, the reinforcing arrangement 20 can be selected from material with its rigidity harder than the supporting base 10, such as the ceramic material, the metal, and hardened glass. The bottom wall 11 and the reinforcing arrangement 20 can be made from two different material such that the cushioning capability of the bottom wall 11 is superior than the reinforcing arrangement 20, while the intensity of the reinforcing arrangement 20 is stronger than the bottom wall 11. By this arrangement, not only will the bottom wall 11 be ensured from warping, but also will the glass substrate be properly supported and cushioned.
In other embodiments, the number of the reinforcing ribs 21 will not be limited by the current embodiment, for example, it can be one reinforcing rib, or three reinforcing ribs other than two reinforcing ribs. In order to have the bottom wall 11 be incorporated with better stiffness to withhold the warpage, preferably, there are more than two reinforcing ribs 21. On the other hand, the arrangement of the reinforcing ribs 21 is not limited to longitudinal direction. For example, the pair of reinforcing ribs or more than two reinforcing ribs can be arranged in transversal across the bottom wall 11 or they can be arranged with a certain angle with respect to the longitudinal direction, but still are in parallel to each other.
The manufacturing of the packaging device 1 can be implemented with different ways; preferably, the reinforcing arrangement 20 and the supporting base 10 can be integrally formed. For example, the reinforcing arrangement 20 is property disposed within a mold cavity of the supporting base 10, and then have the supporting base 10 formed within the mold cavity with the reinforcing arrangement embedded therein. Alternatively, the supporting base 10 can be molded firstly, and then attach to the supporting base 10 with any proper way currently available to the skill in the industry.
Regarding the relationship between the supporting base 10 and the reinforcing arrangement 20, the reinforcing arrangement 20 can be completely embedded within the supporting base 10 or partially exposed out of the supporting base 10. With respect to the embodiments in which the reinforcing arrangement is disposed on the bottom wall 11, one of the feasible way to fulfill is to create a plurality of through hole, and then insert the reinforcing ribs 21 therein, or, having the supporting base 10 and the reinforcing ribs 21 integrally formed together. With respect to the embodiments in which the reinforcing arrangement 20 is partially exposed out of the base wall 11, this can be implemented by providing retaining portion over the inner surface or bottom surface of the bottom wall 11, and then insert the reinforcing ribs 21 into those retaining portion.
