Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil production technology, and specifically relates to a battery aluminum foil roll packaging box that can be transferred backwards. Background Technology

[0002] With strong government support and guidance for new energy vehicles, the industry has experienced rapid development. This has led to a surge in demand for lithium-ion batteries, placing higher demands on their performance. Against this backdrop, reducing costs and improving performance have become the development goals of the lithium-ion battery industry. One way to improve performance is by increasing the contact area between the current collector and the active particles, thereby enhancing the electron transfer capacity during charging and discharging and ultimately improving the electrochemical performance of the lithium-ion battery. Carbon-coated aluminum foil technology has proven to be an effective method in practice.

[0003] Aluminum foil is typically transported via packaging boxes. For example, patent application number CN202420209420.X discloses an aluminum foil roll packaging box, which includes a box body arranged in the front-to-back direction, a bottom support at the bottom of the box body, a cover plate at the top of the box body, and two support components at the front and rear ends of the box body. The support components include an upper insert plate and a lower insert plate arranged opposite each other and located on the upper and lower sides of the aluminum foil roll body, respectively. The cover plate is fixed to the box body by N left-to-right binding straps. The lower side of the cover plate has two anti-slip strips arranged side by side in the front and back, and the upper side has N grooves arranged side by side in the front and back to cooperate with the binding straps. The anti-slip strips and grooves are arranged in the left-to-right direction. The two anti-slip strips are located between the two support components and the corresponding front or rear side of the box body, respectively. The tops of the N binding straps are embedded in the N grooves. The box body is a rectangular box body, the cover plate is a rectangular plate that fits with the box body, the upper insert plate and the lower insert plate are both rectangular plates that fit with the box body and their opposite sides are provided with semi-circular grooves that fit with aluminum foil rolls. The left and right sides of the box body are provided with slots for the downward insertion of support components. The lower end of the lower insert plate abuts against the bottom of the box body, and the top of the upper insert plate abuts against the lower side of the cover plate.

[0004] After the aluminum foil is prepared, it is suspended in the first packaging box using the first threading rod for transport to the carbon coating manufacturer for carbon coating. After carbon coating, it is suspended in the second packaging box using the second threading rod (fixed length, slightly larger than 1350mm, a standard specification for battery manufacturers and the industry default length) for transport. Typically, if the lengths of the first and second threading rods are different, the packaging box needs to be changed after carbon coating, costing several hundred yuan per box, increasing the manufacturer's costs.

[0030] Two support components 3 are respectively located at the left and right ends of the housing 1, each including two first insert plates 31, both arranged along the front-to-back direction. The two first insert plates 31 are arranged vertically opposite each other, located on the upper and lower sides of the material feed rod 5, respectively. Each of their opposite ends is provided with a semi-circular hole 32 (with the same diameter as the material feed rod 5) that mates with the material feed rod 5. The first insert plate 31 is a rectangular plate that mates with the width direction of the housing 1, and its front and rear ends are respectively inserted into the first slots 6 on the corresponding sides. The upper end of the upper first insert plate 31 is located on the lower side of the cover plate 2, and the lower end of the lower first insert plate 31 rests against the bottom of the housing 1. The semi-circular holes 32 are located at the middle of the upper end of the first insert plate 31 (lower first insert plate 31) or the middle of the lower end (upper first insert plate 31), and the two semi-circular holes 32 form a circular hole.

[0031] The partition assembly 4 is detachably installed inside the housing 1, located in the middle of the housing 1, dividing the housing 1 into two parallel slots arranged along the front-to-back direction. The partition assembly 4 is specifically located on the centerline of the housing 1. The partition assembly 4 includes two second insert plates 41. The two second insert plates 41 are arranged vertically opposite each other, located on the upper and lower sides of the material feed rod 5, respectively. Each of their opposite ends has a semi-circular groove 42 (with the same diameter as the material feed rod 5) that mates with the material feed rod 5.

The threading rod 5 is a short threading rod (slightly less than half the length of the box 1). When packaging one aluminum foil roll, the aluminum foil roll is coated with a plastic core, located between the two support assemblies 3. The threading rod 5 is a long threading rod (slightly less than the length of the box 1). The length of the box 1 matches the length of the long threading rod, which is longer than the sum of the lengths of the two short threading rods. The long and short threading rods have the same outer diameter. The threading rod 5 is inserted into the core, with both ends protruding (slightly protruding), and is used to suspend the aluminum foil roll.
