Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of packaging, and particularly relates to a packaging structure for optical lenses. Background Art
[0002] Due to the requirements of optical lenses for surface finish, when packaging optical lenses, the packaging materials in direct contact with the optical lenses are required to be soft in texture to avoid surface defects such as scratches on the optical lenses caused by accidental collisions and frictions; and because most optical lenses are relatively brittle, the design of their packaging should consider the use of materials with higher hardness and better toughness, so as to withstand damage caused by unexpected external pressure during transportation. Infrared polished and coated optical lenses are optical lenses that are processed after polishing and coating processes of infrared materials such as zinc selenide, zinc sulfide, germanium wafers, silicon wafers, chalcogenide glass, calcium fluoride, and magnesium fluoride. Compared with ordinary optical lenses, the packaging requirements of this optical lens are more stringent.
[0003] The current packaging solution for lenses is generally: wrap them with dust-free paper, put them into the grooves of the tray with precious cotton, stack multiple trays, and then cover them and put them into the outer packaging box. This packaging method has the following shortcomings for optical lenses with strict surface quality requirements:
[0004] (1) Multiple pallets are wrapped together with transparent tape, which has limited ability to protect against external forces. During transportation, the pallets may still be deformed by external forces, causing damage to the internal products.
[0005] (2) Using dust-free paper can easily scratch the surface of the optical lens, causing the surface quality of the lens to fail to meet quality requirements.
[0006] (3) Although the tray is made of low-density pearl cotton, its softness is still not enough to hold polished and coated optical lenses. The lenses are easily scratched due to friction during the process of putting them in and taking them out.
[0007] (4) The outer packaging boxes made of wood, aluminum alloy and other materials are more expensive than cardboard boxes and have a low cost-performance ratio.
[0008] (5) It is necessary to combine multiple materials such as pearl cotton boxes and cover plates together and wrap them with transparent tape to achieve the function of a single independent packaging box, and the operation is relatively complicated.
[0009] The existing lens packaging method also uses a hard protective box to package the lenses, and then limits the hard protective box by the groove of the soft tray. However, this packaging structure is not suitable for the transportation of multiple layers of hard protective boxes. In addition, the volume occupied by the soft tray in the outer packaging box is large, and the lenses packaged are limited. Utility Model Content
[0010] In order to solve the above problems, the utility model provides a packaging structure for optical lenses, which can effectively prevent damage to the optical lenses caused by external forces during storage and transportation.
[0011] A packaging structure for optical lenses, comprising an outer packaging box, at least one sponge packaging body and at least one hard protective box;
[0012] The sponge packaging body comprises a packaging body and a packaging cover; the packaging body is provided with a plurality of receiving grooves for receiving the optical lenses; the packaging cover is used to cover the notches of the receiving grooves;
[0013] The sponge packaging body is fixed in the hard protective box;
[0014] The hard protective box is fixed in the outer packaging box.
[0015] In this solution, when the outer packaging box is subjected to force, the effect of the external force on the internal product is reduced through the action of the outer packaging box and the hard protective box. The sponge packaging body is arranged in the hard protective box, and the optical lens is stored and limited by the receiving groove on the packaging body. The optical lens is provided with all-round flexible protection by the packaging cover and the packaging body made of sponge material.
[0016] Furthermore, the hard protective box includes a box body and a protective cover; the packaging body is embedded in the box body, and the packaging cover is embedded in the protective cover.
[0017] Furthermore, the protective cover is snap-connected to the box body.
[0018] Furthermore, the receiving groove is provided with one or more size specifications, and the size specifications are adapted to the optical lens.
[0019] Furthermore, the hard protective boxes are provided in plurality, each of which contains a sponge packaging body; the plurality of hard protective boxes are arranged in close contact with each other in the outer packaging box.
[0020] Furthermore, the material of the hard protective box is polypropylene, which has the advantages of excellent resistance to impact, heavy pressure and collision; and the use of polypropylene material makes the hard protective box have excellent sealing properties, providing better sealing conditions for effectively isolating the air and slowing down the surface oxidation rate for storing polished / coated lenses.
[0021] Furthermore, the outer packaging box is a double corrugated cardboard box.
[0022] Furthermore, pearl cotton is arranged between the inner surface of the outer packaging box and the hard protective box.
[0023] Furthermore, a protective layer is included, and the protective layer is configured to directly contact the optical lens and isolate the optical lens from the groove wall of the accommodating groove and the packaging cover.
[0024] Furthermore, the protective layer is a capacitor paper or an antistatic protective film. According to the optical lenses of different materials, different protective layers such as capacitor paper and antistatic protective film are used to wrap the lenses, further avoiding damage to the lens surface caused by external factors.
[0025] Compared with the prior art, one or more of the above technical solutions can achieve at least one of the following beneficial effects:
[0026] (1) The packaging structure of the optical lens is shock-resistant and pressure-resistant, and can effectively prevent the lens from being damaged by external forces during transportation. Specifically,
[0027] An overall protection solution is provided: a hard protective box is used as the main material for external force. After the individually packaged hard protective boxes are arranged in a certain order and packed into the outer packaging carton, the entire packaging box forms a whole, and its ability to resist external extrusion is greatly enhanced, which can minimize the damage that may be caused to the lenses during transportation;
[0028] Sponge is used as the inner packaging to play a buffering and limiting role for the lens. The sponge is softer than the pearl cotton in the prior art and can better avoid damage caused by friction during the process of putting in and taking out the lens.
[0029] (2) The packaging structure of the optical lens can realize the packaging of optical lenses of various specifications, solving the problem of repeated design and packaging of lenses of various specifications. Specifically,
[0030] The sponge packaging body can be provided with receiving grooves of different sizes to accommodate optical lenses of different specifications. When choosing a hard protective box, you can choose to purchase conventional sizes. You only need to properly adjust the design of the built-in sponge packaging body to achieve the function of packaging multiple lenses in the same specification hard protective box;
[0031] For the same design of built-in sponge packaging body, the function of packaging multiple lenses can also be achieved by changing the wrapping thickness of the electrostatic protection film or capacitor paper or adjusting the folding method.
[0032] (3) The packaging structure of the optical lens is simple and convenient to operate, which improves the packaging efficiency. Specifically, the sponge packaging body and the hard protective box are formed as a matching package and can be put together for use; when packaging, it is only necessary to wrap the optical lens with the protective layer and put it into the receiving slot, buckle the protective cover, and then stack the entire hard protective box layer by layer in a certain order into the outer packaging box.
[0033] (4) The packaging structure of the optical lens can be used to package a larger number of lenses. Specifically,
[0034] Since the protection of the hard protective box made of PP plastic material is added on the basis of the outer packaging box, in view of the excellent compression and shock resistance of the PP plastic material itself, and the overall protective effect formed by multiple hard protective boxes, the distance between the receiving grooves, the distance between the receiving grooves and the edges, and the thickness of the upper and lower sponge packaging bodies can be reduced in the design of the sponge packaging body, which greatly reduces the volume of the buffer material inside the hard protective box, and more lenses can be packaged under the premise of protecting the lens surface;
[0035] Furthermore, the hard protective cases can be stacked one on top of the other and provided with multiple layers, thereby further increasing the capacity of accommodating lenses.
[0036] (5) The packaging structure cost of the optical lens is relatively low. Specifically,
[0037] Due to the flexibility of the sponge packaging design, the hard protective box can be standardized without the need for additional mold costs;
[0038] Due to the excellent compression and shock resistance of the hard protective box and the overall protective effect formed by multiple hard protective boxes, the outer packaging box can use a double corrugated cardboard box instead of using an outer packaging box made of higher-cost materials such as wood and aluminum alloy, which can meet the compression and shock resistance requirements of optical lens packaging.

[0046] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0047] Example 1
[0048] like Figures 2 to 4 As shown, this embodiment provides a packaging structure for optical lenses, including an outer packaging box (not shown in the figure), at least one hard protective box 2 and at least one sponge packaging body 1; the sponge packaging body 1 is provided with a plurality of accommodating grooves 13 for accommodating optical lenses; the sponge packaging body 1 is fixed in the hard protective box 2; the hard protective box 2 is fixed in the outer packaging box.
[0049] As a specific implementation method, Figure 1 As shown, the sponge packaging body 1 includes a packaging body 11 and a packaging cover 12, a receiving groove 13 is provided on the packaging body 11, and the packaging cover 12 is used to cover the notch of the receiving groove 13. The receiving grooves 13 are arranged in an array on the packaging body 11; the size specifications of the receiving grooves 13 can be set to one or more according to the size specifications of the optical lens to be packaged. The receiving groove 13 in this embodiment is a square groove, and it can be understood that the shape of the receiving groove 13 can be specifically designed according to the shape of the optical lens, such as setting it in a circular arc shape.
[0050] The packaging structure also includes a protective layer (not shown in the figure), which is configured to directly contact the optical lens and isolate the optical lens from the groove wall of the receiving groove 13 and the packaging cover 12. The protective layer is capacitor paper or an antistatic protective film. In specific implementation, the optical lens can be wrapped by the protective layer to avoid direct contact with the groove wall of the receiving groove 13 and the packaging cover 12. According to the different materials of the optical lens, the most suitable inner packaging material is selected as the protective layer: for example, for germanium polishing sheets and silicon wafers with slightly higher hardness, capacitor paper is used for wrapping; and for zinc selenide and zinc sulfide with slightly softer materials, PE antistatic protective film can be used for wrapping, which can minimize the damage caused to the polished surfaces of different materials during the packaging process, and can also avoid other defects such as watermarks.
[0051] The hard protective box 3 includes a box body and a protective cover. As an embodiment, the connection between the protective cover and the box body can be a snap connection. As a preferred embodiment, the hard protective box is a PP plastic box; PP plastic is not only healthy, hygienic, and beautiful, but also has high temperature resistance, impact resistance, and good sealing properties; especially considering hardness and toughness, PP plastic is an ideal material for optical lens packaging. The sponge packaging body 1 is arranged in the hard protective box 2. Specifically, the packaging body 11 is embedded in the box body, and the packaging cover 12 is embedded in the protective cover. In this way, the packaging cover 12 can be opened by opening the protective cover. In the present embodiment, the packaging cover 12 is a whole cover. It can be understood that the packaging cover is designed to be a plurality of covers embedded in the protective cover, and it is also possible to cover the notch of the receiving groove 13.
[0052] like Figure 5 As shown, there are multiple hard protective boxes 2, such as 4 in the figure, and the 4 hard protective boxes 2 are arranged in a close relationship with each other, and a sponge packaging body 1 is arranged in each hard protective box 2. When the hard protective boxes 2 are arranged in a close relationship, they can be stacked vertically as shown in the figure, or they can be arranged horizontally. Multiple hard protective boxes 2 are arranged in multiple layers and rows in order and stuck in the outer packaging box. In the specific implementation, pearl cotton can be arranged between the inner surface of the outer packaging box and the hard protective box 2, so that the hard protective box 2 is fixed in the outer packaging box. As a specific embodiment, the outer packaging box is a double corrugated cardboard box. In this embodiment, under the condition of peripheral protection of the outer packaging box, another protection inside the hard protective box is added to the inner packaging, which can well prevent the sponge from being deformed due to extrusion; after the hard protective boxes are arranged and packed in a certain order, the packaging as a whole can withstand the extrusion of greater external forces, and the polished and coated optical lenses are protected to the greatest extent when using cartons.
[0053] In this embodiment, a sponge packaging body is provided to package the optical lens. On the one hand, compared with pearl cotton, the sponge is obviously much softer in material, and is an ideal choice as a built-in buffer material for polished / coated optical lenses. On the other hand, the sponge can be molded into various shapes as needed, which is convenient for processing. The shape and specifications of the sponge packaging body built into the hard protective box can be designed and adjusted as needed, so that the function of packaging lenses of various specifications in the hard protective box of the same specification can be realized. The accommodating groove is provided with one or more size specifications, and its size specifications are compatible with the optical lens. Take the sponge packaging body and the hard protective box as a square as an example. For example, the internal dimensions of the hard protective box body are 176mm long × 147mm wide × 39mm deep, and the built-in sponge packaging body can be designed in two different sizes to package lenses with a diameter of 18 to 30mm: one sponge packaging body has a receiving groove with the dimensions of 26mm long × 5mm wide × 20mm deep, the sponge thickness at the bottom of the packaging body is 10mm, and the sponge thickness at the packaging cover is 9mm; the other sponge packaging body has a receiving groove with the dimensions of 26mm long × 5mm wide × 27mm deep, the sponge thickness at the bottom of the packaging body is 6mm, and the sponge thickness at the packaging cover is 6mm.
[0054] Obviously, the above embodiments are merely examples for clearly illustrating the technical solution of the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection of the claims of the utility model.
