Description

Technical Field

[0001] The present invention relates to a packaging structure and a conveying device, and particularly to a packaging structure and a conveying device for carrying and conveying optical sheets. Background Art

[0002] Generally, a vacuum forming box (commonly known as a TRAY tray in the industry) is used to carry or handle semi-finished products such as light guide plates or backlight modules. However, the overall shape of the vacuum forming box needs to be designed according to the outer shapes of various carrying objects, resulting in it not being universal for various different sizes or styles. In addition, its four corners require a top support structure to prevent the carried object from slipping in the horizontal direction, so the overall structure is relatively complex. Moreover, in order to save the volume of the vacuum forming box, its thickness is usually designed to be ultra-thin, which makes it prone to deformation due to collision or stacking.

[0003] Furthermore, the vacuum forming box is designed to be placed flat, and during transportation, it prevents the carried object from moving in the vertical direction by being stacked and pressed up and down. However, due to the forming tolerance during the mold forming process of the vacuum forming box, when stacking up and down, it may cause the upper vacuum forming box to directly press on the carried object in the lower vacuum forming box, or ineffective pressing may occur due to inaccurate stacking. Summary of the Invention

[0004] Therefore, an object of the present invention is to provide a packaging structure that can be shared by multiple sizes and can generate a fixing effect by itself.

[0005] The packaging structure of the present invention is used to carry at least one object.

One side of the film is arranged on the coating layer corresponding to the end of the support plate far from the side plate, and the other side of the film is arranged on the coating layer corresponding to the end of the side plate far from the support plate. The object is placed on the support plate, and the area of the support plate is greater than the area of the object. When the side plate bends downward relative to the support plate, the film will be stretched, and the object will be clamped and positioned between the film and the support plate.

[0009] Another technical means of the present invention lies in that the carrying unit includes a support plate with a hardness greater than that of the object, two side plates respectively located on opposite sides of the support plate, and a coating layer tightly covering the support plate and the two side plates. There is a gap between each side plate and the support plate so that it can bend relative to the support plate. Two sides of the film are respectively arranged on the coating layer corresponding to the ends of the two side plates far from the support plate. The object is placed on the support plate, and the area of the support plate is greater than the area of the object. When the two side plates bend downward relative to the support plate, the film will be stretched, and the object will be clamped and positioned between the film and the support plate.

[0010] Another technical means of the present invention lies in that the support plate and the side plates are long fiber wood boards, and the coating layer is copperplate paper plated with an anti-slip layer, and the anti-slip layer contacts the object.

[0011] Another technical means of the present invention lies in that the carrying unit includes a support plate with a hardness greater than that of the object, a carrier platform arranged on the support plate and having an area smaller than that of the support plate, and a cover plate capable of covering the support plate. The cover plate is in a hollow ring shape and surrounds a through opening. The area of the carrier platform is smaller than the area of the opening. When the cover plate is closed, the carrier platform is located in the opening and does not interfere with each other. The film is arranged on the side of the cover plate facing the support plate and blocks the opening. The object is placed on the carrier platform, and the sum of the thicknesses of the object and the carrier platform is greater than the thickness of the cover plate.

[0012] Another technical means of the present invention lies in that one side of the cover plate is connected to one side of the support plate and can be opened and closed relative to the support plate.

[0013] Another technical means of the present invention lies in that the cover plate is not connected to the support plate.

[0014] Another technical means of the present invention lies in that the thickness of the stage is 100% to 130% of the thickness of the cover plate.

[0015] Another technical means of the present invention lies in that a plurality of microstructures are formed on the side of the film facing the carrying unit.

[0016] Another technical means of the present invention lies in that the ratio of the length of the film to the length of the carrying unit is 0.9 - 0.97:1.

[0017] Another technical means of the present invention lies in that the film is made of a non - sticky material and the antistatic resistance value is ≤ 10^10 Ω.

[0018] Another technical means of the present invention lies in that the anti - slip grade of the surface of the carrying unit in contact with the object is ≥ R11.

[0019] Another object of the present invention is to provide a transporting device for use in conjunction with the aforementioned packaging structure.

[0020] The transporting device of the present invention is used to clamp and position a plurality of the aforementioned packaging structures in an upright manner and includes a plurality of fixing units, which are respectively clamped and positioned at at least two corners of the packaging structure. Among them, each fixing unit includes a body extending along the X - axis direction and in a long - strip shape, and a plurality of accommodating grooves recessed in parallel at intervals along the Y - axis direction on the body. The body has a first surface and a second surface opposite to the first surface. The accommodating grooves are recessed from the first surface towards the second surface and do not extend to the second surface. Each accommodating groove has a tapered section with a width gradually decreasing from the first surface towards the second surface.

[0021] Another technical means of the present invention lies in that each accommodating groove further has an extending section communicating with the tapered section and having a constant width and extending towards the second surface. The width of the extending section is slightly larger than the thickness of the carrying unit, so that the carrying unit can be clamped in the accommodating groove.

[0022] Another technical means of the present invention lies in that the body of each fixing unit further has a third surface connecting the first surface and the second surface, and a fourth surface connecting the first surface and the second surface and opposite to the third surface. The third surface faces the packaging structure. The accommodating grooves are recessed from the third surface towards the fourth surface and do not extend to the fourth surface.

[0023] Another technical means of the present invention lies in that the conveying device further includes a bottom plate having an upper surface, and two of the plurality of fixing units are disposed on opposite sides of the upper surface of the bottom plate, and the accommodating grooves of the two fixing units are aligned with each other.

[0024] Another technical means of the present invention lies in that the number of the fixing units is four, and they are respectively clamped and positioned at four corners of the packaging structure.

[0038] The related technical content of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the accompanying drawings. Before the detailed description, it should be noted that similar elements are denoted by the same reference numerals.

[0039] Refer to Figure 1 and Figure 2 , which is a first preferred embodiment of the packaging structure of the present invention, and includes a carrying unit 1 and a film 2 that is stretchable and disposed on the carrying unit 1.

[0040] The carrying unit 1 includes a support plate 11 and two side plates 12 that are respectively connected to opposite sides of the support plate 11 and can be bent relative to the support plate 11. Both sides of the film 2 are respectively disposed at one ends of the two side plates 12 away from the support plate 11. As Figure 1 shown, the outer sides of the two side plates 12 respectively have glue application areas 121 so that both sides of the film 2 are respectively adhered to the two glue application areas 121. Of course, the two sides of the film 2 can also be fixed to the support plate 11 by nailing or buckling, but this is not limited thereto.

[0041] Refer to Figure 2 , since the ratio of the length of the film 2 to the length of the carrying unit 1 is 0.9 to 0.97:1, that is, the length of the film 2 is slightly less than the total length of the carrying unit 1. Therefore, when both sides of the film 2 are fixed to the carrying unit 1, the outer sides of the two side plates 12 will be slightly lifted upward due to the stretchability of the film 2 to form a state as Figure 3 shown, and a gap is formed between the film 2 and the support plate 11. This gap is used for the optical sheet 9 (see Figure 4 ) to enter and exit therefrom and be placed on the carrying surface of the support plate 11. Of course, in order to achieve a good carrying effect, the hardness of the support plate 11 must be greater than that of the optical sheet 9, and at the same time, the area of the support plate 11 must also be greater than the area of the optical sheet 9. In this embodiment, the support plate 11 and the two side plates 12 can be made of cardboard, wood board, plastic board, etc., but this is not limited thereto.

[0042] In use, the optical sheet 9 enters through the gap between the film 2 and the support plate 11 and is placed on the support plate 11, and the two side plates 12 are bent relative to the carrying surface of the support plate 11 toward the other side to form a state as Figure 4In the state shown, at this time, when the film 2 is synchronously stretched, the optical sheet 9 can be clamped and positioned between the film 2 and the support plate 11.

[0043] In addition, in order to enhance the positioning effect of the optical sheet 9, a plurality of microstructures are formed on the surface of the film 2 facing the loading unit 1. In this embodiment, microstructures similar to snake skin patterns are formed. This, combined with the anti-slip grade of the surface of the loading unit 1 in contact with the optical sheet 9 being ≥ R11 (refer to the anti-slip test specification of DIN51130, the higher the grade, the better the anti-slip effect), can improve the fixing effect and prevent the optical sheet 9 from sliding on the support plate 11 and causing scratches. It should be noted that to achieve an anti-slip grade of ≥ R11 for the loading unit 1, surface treatments such as atomization can be performed on the surface of the loading unit 1 that is to be in contact with the film 2, or anti-slip diaphragms that increase resistance can be pasted, such as PP fog film, PET bright film, or EPE film, etc., but it is not limited thereto.

[0044] When removing the optical sheet 9 from the loading unit 1, only need to first expand the two side plates 12 from Figure 4 to the state shown in Figure 3 , and then tilt the loading unit 1, then the optical sheet 9 can slide out from between the film 2 and the support plate 11. Since the film 2 is a non-adhesive material and the antistatic resistance value ≤ 1010 Ω, the film 2 will not adhere to the optical sheet 9, so that the optical sheet 9 can smoothly leave the loading unit 1.

[0045] It should be specifically noted that as shown in Figure 2 , in this embodiment, the two side plates 12 are connected to the opposite sides of the support plate 11. In order to enable the two side plates 12 to bend relative to the support plate 11, at the connection 13 between the two side plates 12 and the support plate 11, a design with a thinner thickness or formed with cutting marks can be used, so that the two side plates 12 can smoothly perform the bending action.

[0046] In addition, in this embodiment, the design that both sides of the support plate 11 are connected and provided with side plates 12 is utilized. Of course, in actual implementation, it can also be as shown in Figure 5 , only one side of the support plate 11 is connected and provided with a side plate 12, one side of the film 2 is arranged at one end of the support plate 11 away from the side plate 12, and the other side is arranged at one end of the side plate 12 away from the support plate 11. Thereby, the aforementioned effect of positioning the optical sheet 9 can be achieved, and the overall structure and manufacturing cost can be made more concise.

[0047] Refer to Figure 6, which is the second preferred embodiment of the packaging structure of the present invention, includes a carrying unit 3 and a film 4 with stretchability disposed on the carrying unit 3. The carrying unit 3 includes a support plate 31, two side plates 32 respectively located on opposite sides of the support plate 31, and a covering layer 33 tightly covering the support plate 31 and the two side plates 32. Among them, the two side plates 32 are not directly connected to the support plate 31, but there is a gap between them and the support plate 31, and the covering layer 33 covers the two side plates 32 and the support plate 31 to make them an integral body, so that the two side plates 32 can be bent relative to the support plate 31. Both sides of the film 4 are respectively disposed on the covering layer 33 corresponding to the ends of the two side plates 32 away from the support plate 31.

[0048] It should be noted that the support plate 31 and the side plates 32 can be made of cardboard that has been strengthened and moisture-proof treated, or materials with better moisture resistance such as wooden boards or plastic boards, to ensure that the support plate 31 can still maintain a certain structural strength after use. The covering layer 33 is a copperplate paper 332 plated with an anti-slip film 331, and the carrying unit 3 contacts the optical sheet 9 through the anti-slip film 331. Among them, the anti-slip film 331 can be, for example, a PE film (Polyethylene), a PP film (Polypropylene), a PVC film (Polyvinyl Chloride), or an EPE film (Expandaple polyephylene), etc., but is not limited thereto.

[0049] The usage and operation steps of this embodiment are the same as those of the first preferred embodiment, so it can also achieve the effect of stretching the film 4 by bending the side plates 32 to press and position an optical sheet (not shown in the figure).

[0050] In addition, similarly, in this embodiment, the side plates 32 can also be arranged at intervals on only one side of the support plate 31, and then the support plate 31 and the side plates 32 are tightly covered by the covering layer 33. This structure can be understood by those of ordinary skill in the art and will not be shown separately. Thereby, the above-mentioned effect of positioning the optical sheet can also be achieved, and the overall structure and manufacturing cost can be made more streamlined.

[0051] Refer to Figure 7, which is the third preferred embodiment of the packaging structure of the present invention, includes a carrier unit 5 and a film 6 that is stretchable and disposed on the carrier unit 5. In this embodiment, the carrier unit 5 includes a support plate 51, a stage 52 disposed on the support plate 51 and having an area smaller than that of the support plate 51, and a cover plate 53 that can be closed relative to the support plate 51. In this embodiment, the cover plate 53 is not connected to the support plate 51 but forms an up-and-down closing form. Among them, the cover plate 53 is in a hollow ring shape and defines a through opening 531. The film 6 is disposed on the side of the cover plate 53 facing the support plate 51 and blocks the opening 531. The dotted line part is the edge of the film 6. The film 6 can be fixed to the cover plate 53 by means of adhesion, nailing or buckling, but is not limited thereto. As Figure 8 shown, the area of the stage 52 is smaller than the area of the opening 531, and when the cover plate 53 is closed on the support plate 51, the stage 52 is located within the opening 531 and does not interfere with each other.

[0052] Referring to Figure 9 , in use, the optical sheet 9 is placed on the stage 52, and since the sum of the thicknesses of the optical sheet 9 and the stage 52 is greater than the thickness of the cover plate 53, when the cover plate 53 is closed on the support plate 51, the optical sheet 9 will push the film 6 upward, thereby being able to press and position the optical sheet 9 on the stage 52 by using the stretchability of the film 6. In this embodiment, the thickness of the stage 52 is designed to be 100% to 130% of the thickness of the cover plate 53 to ensure that when the cover plate 53 is closed, the optical sheet 9 can indeed contact the film 6 and push the film 6 upward. More specifically, when the thickness of the stage 52 is less than 100%, there will be insufficient tensile force when the film 6 is closed on the stage 52, resulting in poor pushing effect and easy sliding of the optical sheet 9; when the thickness of the stage 52 exceeds 130%, problems such as excessive stretching of the film 6 and difficulty in recovery or easy breakage are likely to occur.

[0053] In addition, it should be noted that in the preferred embodiment, it can also be as Figure 10 shown, one side of the cover plate 53 is connected to one side of the support plate 51 and can be lifted and closed relative to the support plate 51, thereby reducing the chance of the cover plate 53 detaching from the support plate 51 and providing another usage mode.

[0054] Referring to Figure 11 , which is the preferred embodiment of the transporting device of the present invention, is used to clamp and position a plurality of the aforementioned packaging structures in an upright manner and includes four fixing units 7 and a bottom plate 8. The bottom plate 8 has an upper surface 81. Among them, two fixing units 7 are disposed on opposite sides of the upper surface 81 of the bottom plate 8. The four fixing units 7 respectively clamp and position the four corners of the packaging structure.

[0055] Among them, each fixing unit 7 includes a strip-shaped body 71 extending along the X-axis direction, and a plurality of receiving grooves 72 recessed in parallel at intervals in the body 71 along the Y-axis direction. The receiving grooves 72 of the two fixing units 7 provided on the bottom plate 8 are aligned with each other. Each body 71 has a first surface 711, a second surface 712 opposite to the first surface 711, a third surface 713 connecting the first surface 711 and the second surface 712, and a fourth surface 714 connecting the first surface 711 and the second surface 712 and opposite to the third surface 713. The receiving groove 72 is recessed from the first surface 711 toward the second surface 712 and does not extend to the second surface 712. At the same time, it is recessed from the third surface 713 toward the fourth surface 714 and does not extend to the fourth surface 714. By means of the design that the receiving groove 72 is not penetrated in both the Y-axis direction and the Z-axis direction, the limiting effect is achieved.

[0056] Referring to Figure 12 , each receiving groove 72 has a tapered section 721 whose width tapers from the first surface 711 toward the second surface 712, and an extension section 722 communicating with the tapered section 721 and having a constant width and extending toward the second surface 712. As Figure 11 and Figure 12 shown, the width of the extension section 722 is slightly larger than the thickness of the carrying unit 5, so that the carrying unit 5 is clamped in the receiving groove 72.

[0057] In use, both sides of the carrying unit 5 of the packaging structure are respectively positioned on the two fixing units 7 provided on the bottom plate 8. Due to the design that the opening of the tapered section 721 of each receiving groove 72 is wider, the carrying unit 5 of the packaging structure can be more easily slid into the receiving groove 72, and the packaging structure is clamped and positioned through the extension section 722 of the receiving groove 72. Finally, two fixing units 7 are respectively arranged at two corners above the packaging structure, so that the four corners of the packaging structure are all received and positioned in the receiving grooves 72 of the four fixing units 7 for complete protection and positioning.

[0058] When an optical sheet is placed inside the packaging structure, with the above design, the packaging structure can be made to stand upright and positioned at intervals, which can not only increase the storage quantity, but also avoid the situation that the optical sheet is damaged due to the stacking method. Furthermore, the receiving groove 72 has a length in the Y-axis direction, so packaging structures of different sizes can be placed and positioned, and there is no need to manufacture different-sized transportation devices according to various sizes of packaging structures, reducing the manufacturing cost and storage space.

[0059] In summary, for the packaging structure of the present invention, as long as the optical sheet is placed on the bearing unit, the optical sheet can be positioned on the support plate for transportation through the stretchability of the film, and the film will not adhere to the optical sheet. Thus, the optical sheet can be easily removed from the bearing unit for subsequent use. Together with the structural design of the transportation device of the present invention, it can be applicable to packaging structures of different sizes or specifications, and can be stored and transported in an upright arrangement. Thereby, the damage that may be caused by stacking up and down can be reduced, and at the same time, the storage and transportation quantity can be increased, and the production cost can be reduced.

[0060] The above are only the preferred embodiments of the present invention, and the scope of implementation of the present invention should not be limited thereby. That is, all simple equivalent changes and modifications made according to the scope of the claims of the present invention and the content of the specification of the present invention still fall within the scope covered by the patent of the present invention.
