Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, and in particular to a waterproof packaging box for lithium battery production. Background Technology

[0002] Lithium battery production is a complex industrial process involving multiple stages and high technical requirements. Production begins with the preparation of raw materials, which requires the acquisition of key substances such as positive electrode materials (such as lithium cobalt oxide and lithium iron phosphate), negative electrode materials (such as graphite), electrolytes, and separators. Finally, after rigorous testing and packaging, lithium batteries can enter the market and be widely used in mobile phones, electric vehicles, energy storage systems and other fields, providing strong power support for modern life and industrial development.

[0003] Lithium battery production requires packaging boxes, but existing packaging boxes typically use corrugated cardboard to package lithium batteries. However, cardboard boxes are not waterproof, making them prone to water ingress. When lithium batteries come into contact with water, water may seep into the battery, causing a short circuit between the positive and negative terminals, leading to overheating, fire, or even explosion, posing a serious threat to personnel and property safety. Furthermore, cardboard boxes are easily deformed and damaged when exposed to water, leaving the lithium batteries exposed and requiring repackaging, which increases packaging material and production costs.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1:

[0026] Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a waterproof packaging box for lithium battery production, including a box body 1. The top of the box body 1 is provided with four sets of box cover plates 2. The bottom of the inner cavity of the box body 1 is fixed with a sealing strip 3. The sealing strip 3 is made of silicone and its outer side fits the inner wall of the box body 1. A waterproof component 4 is provided inside the box body 1. A first mounting plate 5 is installed inside the box body 1. A lithium battery body 6 is installed on the top of the first mounting plate 5.

[0027] The box body 1 serves as the main structure of the entire packaging box, providing space for the lithium battery body 6 and other internal components, and playing a basic supporting and protective role. The sealing strip 3 prevents moisture from entering the box from the bottom, further improving the waterproof performance of the packaging box. The waterproof component 4 enhances the waterproof effect of the box body 1 and improves the protection effect of the lithium battery body 6.

[0028] The waterproof component 4 includes a protective layer 41 and a waterproof layer 42 respectively disposed inside the housing 1. The protective layer 41 and the waterproof layer 42 are respectively made of flame-retardant ABS material and aluminum-plastic film material. A filling layer 43 is disposed between the protective layer 41 and the waterproof layer 42. The filling layer 43 is made of polyurethane foam material, and the protective layer 41 and the waterproof layer 42 are sealed by the filling layer 43.

[0029] The protective layer 41 of the flame-retardant ABS material is an acrylonitrile-butadiene-styrene copolymer with added special flame retardants, possessing excellent flame-retardant properties. When exposed to open flames or high temperatures, a carbonized layer quickly forms on its surface, effectively preventing the spread of flames, reducing the burning rate, and providing more time to respond to potential accidents. The waterproof layer 42 of the aluminum-plastic film material consists of three layers of aluminum foil nylon (ON / Al / CPP). The outer nylon layer mainly serves a protective function, preventing the aluminum foil layer from being scratched. The outer material is required to be puncture-resistant and impact-resistant. The middle aluminum foil layer, as the base material, serves as a waterproof and barrier, preventing moisture intrusion and blocking... The polyurethane foam filling layer 43 is an ideal packaging material for electronic products because it is oxygen-barrier to protect the battery contents. Based on its multi-layered structure, it possesses functions such as corrosion resistance, puncture resistance, aging resistance, insulation, and moisture resistance. The filling layer 43 is a porous material with numerous tiny pores. When the packaging box is subjected to external impact, these pores can deform, absorbing and dispersing the impact energy, thus effectively protecting the lithium battery body 6 from damage. The polyurethane foam itself has a certain closed-cell structure, which can prevent moisture penetration. Combined with the waterproof layer 42, it can further improve the waterproof capability of the packaging box, preventing safety issues such as short circuits caused by moisture in the lithium battery.

[0030] Example 2:

[0031] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the top of the first mounting plate 5 is provided with a first protective plate 7 and a second protective plate 8, and both the first protective plate 7 and the second protective plate 8 are provided in two sets.

[0033] The first protective plate 7 and the second protective plate 8 provide side protection for the lithium battery body 6 from different directions, enhancing the protection effect of the lithium battery body 6 and preventing the lithium battery body 6 from being subjected to side collisions and squeezing during transportation.

[0034] Specifically, the inner cavity of the first protective plate 7 is provided with a groove 9 that fits with the outer side of the second protective plate 8, and the outer side of the second protective plate 8 is engaged with the inner wall of the groove 9.

[0035] The groove 9 allows the first protective plate 7 and the second protective plate 8 to be tightly joined together, forming a complete side protection structure, which improves the stability and reliability of the protection.

[0036] Specifically, the top of both the first protective plate 7 and the second protective plate 8 is provided with a sealing gasket 10, and the sealing gasket 10 is made of silicone.

[0037] The sealing gasket 10 improves the seal between the first protective plate 7, the second protective plate 8, and the top structure.

[0038] Example 3:

[0039] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, a buffer pad 11 for protecting the lithium battery body 6 is fixed on the top of the first mounting plate 5, and the buffer pad 11 is made of EVA foam.

[0041] When the packaging box is subjected to vibration or impact, the cushioning pad 11 can absorb and disperse energy, reduce the impact on the lithium battery body 6, and protect the lithium battery body 6 from damage.

[0042] Specifically, a sealing sleeve 12 is fixed to the top of the buffer pad 11 to improve the waterproof seal between the first protective plate 7 and the second protective plate 8 and the lithium battery body 6.

[0043] The sealing sleeve 12 can fill the gaps between the first protective plate 7, the second protective plate 8 and the lithium battery body 6, preventing moisture from entering from these gaps and further enhancing the waterproof effect of the packaging box.

[0044] Specifically, a second mounting plate 13 is provided on the top of the lithium battery body 6. The second mounting plate 13 has the same structure as the first mounting plate 5, and the second mounting plate 13 and the first mounting plate 5 are symmetrically designed to protect the lithium battery body 6.

[0045] The second mounting plate 13 and the first mounting plate 5 together provide vertical protection for the lithium battery body 6, ensuring the stability and safety of the lithium battery body 6 in the packaging box and preventing it from shaking or shifting during transportation. The sealing gasket 10 also improves the sealing between the second mounting plate 13 and the first mounting plate 5.

[0046] In use, the housing 1 serves as the main structure, providing space for the internal components. The silicone sealing strip 3 effectively prevents moisture from entering the housing from the bottom, laying the foundation for subsequent waterproofing measures. The protective layer 41 is made of flame-retardant ABS material; when exposed to open flame or high temperatures, a carbonized layer quickly forms on the surface, preventing flame spread, reducing the burning rate, and providing fire protection. The waterproof layer 42 is made of aluminum-plastic film, composed of three layers of aluminum foil, nylon, ON / Al / CPP. The outer nylon layer is puncture-resistant and impact-resistant, protecting the aluminum foil layer. The middle aluminum foil layer provides a waterproof barrier, preventing moisture and oxygen intrusion, protecting the battery contents. The polyurethane foam filling layer 43 between the two layers not only provides a seal but also absorbs a certain amount of impact energy. This is achieved through the first protective plate. The first and second protective plates 7 and 8 provide side protection for the lithium battery body 6 from different directions to prevent collisions and squeezing during transportation. The second mounting plate 13 and the first mounting plate 5 together provide vertical protection for the lithium battery body 6, ensuring the stability and safety of the lithium battery body 6 in the packaging box and preventing it from shaking or shifting during transportation. The sealing gasket 10 improves the sealing between the second mounting plate 13 and the first mounting plate 5. The buffer pad 11 absorbs and disperses energy when the packaging box is vibrated or impacted, reducing the impact force on the lithium battery body 6. The sealing sleeve 12 can fill the gaps between the first protective plate 7, the second protective plate 8 and the lithium battery body 6 to prevent moisture from entering from these gaps, further enhancing the waterproof effect of the packaging box.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
