[0022] like Figure 1 The battery pole coil packaging unit shown is easy to transport, including an outer aluminum foil bag 2 wrapped in the outermost layer with a sealed cavity and filled with gas. The cavity of the outer aluminum foil bag 3 is filled with air with a temperature of 22°C-28°C and a humidity of less than 0.3%. The outer aluminum foil bag 3 is provided with a pressure gauge for detecting the air pressure in the cavity and a temperature and humidity measurement label for the temperature and humidity in the cavity.

[0023] The transportable battery electrode coil packaging unit also includes a battery electrode reel support disposed within an outer aluminum foil bag 2, and a battery electrode reel unit 3 mounted on the reel support. The reel support comprises a steel inner support seat 5 disposed at the bottom of the outer aluminum foil bag 2, and two inner liner frames 1 disposed on the front and rear sides of the steel inner support seat 5. The battery electrode reel unit 3 is embedded within a vacuumed inner aluminum foil bag 4, with its axial ends embedded between the front and rear inner liner frames 1. The battery electrode reel unit 3 includes a reel, an electrode coil wound around the reel, a PVC film layer and plastic tube wrapped around the outermost surface of the electrode coil, and blister disks that are respectively sleeved and clamped onto the reel and located outside the corresponding baffles.

[0024] Specifically, the battery electrode coil unit 3 is vacuum-packed and placed within the inner aluminum foil bag 4, protecting the electrode coil from direct contact with air and oxidation. The battery electrode coil unit 3 is then securely attached to the battery electrode reel support via its two axial ends. The entire unit is then enclosed within an outer aluminum foil bag 3, which contains air at a temperature of 22°C-28°C and a humidity of less than 0.3%. This prevents the electrode coil from direct contact with the outside air and oxidation, while maintaining a relatively stable temperature and humidity environment throughout transportation, facilitating land, sea, and air transportation.

[0025] The detailed structure is as follows:

[0026] The two inner liner frames 1 supported by the battery pole reel can be installed on the front and rear sides of the steel inner support seat 5 and can be inserted and removed up and down to achieve stable position in the front, back, left and right directions.

[0027] Each liner frame 1 includes a lower liner 11 and an upper liner 12 whose lower portion can be plugged and detachably connected to the upper portion of the lower liner 11 , and a locking mechanism 13 is provided between the lower liner 11 and the upper liner 12 .

[0028] In this embodiment, the upper surface of the lower lining 11 and the lower surface of the upper lining 12 both have positioning grooves and positioning protrusions. When the lower lining 11 and the upper lining 12 are connected, the lower surface of the upper lining 12 and the upper surface of the lower lining 11 are plugged into each other through the positioning protrusions and positioning grooves.

[0029] A lower card slot 111 opening upward is provided in the middle of the upper surface of the lower lining 11, and an upper card slot 121 opening downward is provided on the lower surface of the upper lining 12. When the lower lining 11 and the upper lining 12 are plugged and connected with each other, a positioning card slot for positioning the shaft end of the reel is formed between the lower card slot 111 and the upper card slot 121.

[0030] In this embodiment, the positioning slot has a slot bottom in the shape of a blind hole, and is used to clamp the shaft end of the winding shaft of the battery pole winding unit 3 .

[0031] In order to ensure that the liner frame 1 can not only play the role of buffering, shock absorption, limiting and stabilizing during transportation, but also sufficiently support the weight of the battery pole coil unit 3. In this embodiment, each liner frame 1 includes a plastic shell made of EPP plastic and a steel support pre-embedded in the EPP plastic shell.

[0032] More detailed structure: Figure 3 As shown, each lower lining 11 includes a lower lining plastic shell 112 made of EPP plastic, a load-bearing lower steel support 113 pre-embedded and integrally formed in the lower lining plastic shell 112, a lower card slot 111 opening upward is provided on the lower lining plastic shell 112, and a slot support corresponding to the position directly below the lower card slot 111 is provided on the upper part of the load-bearing lower steel support 113.

[0033] like Figure 4 As shown, each upper liner 12 includes an upper liner plastic shell 122 made of EPP plastic, a load-bearing upper steel support 123 pre-embedded and integrally formed in the upper liner plastic shell 122, and an upper card slot 121 opening downward is provided on the upper liner 12.

[0034] The locking mechanism 13 is arranged between the stressed lower steel support 113 and the stressed upper steel support 123. After the locking mechanism 13 is locked, the lower card slot 111 and the upper card slot 121 form a stable positioning card slot, so that the axial end of the battery pole winding unit 3 can be stably clamped in the positioning card slot.

[0035] The stressed lower steel support 113 extends in the left and right directions and extends out of the upper part of the lower lining plastic shell 112 to form two lower locking ears, and the stressed upper steel support 123 extends in the left and right directions and extends out of the lower part of the upper lining plastic shell 122 to form two upper locking ears.

[0036] The locking mechanism 13 is arranged between the upper locking ear and the corresponding lower locking ear on each side. Figure 1 、 2 As shown, the locking mechanism 13 includes two tensioning rods 131 located on the left and right sides. Each tensioning rod 131 is respectively passed through the upper locking ear and the lower locking ear of the two liner frames 1 in sequence. By setting locking nuts at both ends of the tensioning rod 131, the two tensioning rods 131 are positioned and locked front and back.

[0037] The two tensioning rods 131 not only lock the upper lining 12 and the lower lining 11 of each liner frame 1, but also tighten and lock the left and right sides between the front and rear liner frames 1 by sharing the two tensioning rods 131, thereby preventing the two liner frames 1 from twisting due to force shock during transportation, thereby forming a stable support for the battery pole coil unit 3 clamped in the middle.

[0038] Packaging method of battery pole coil packaging unit for easy transportation:

[0039] When packaging, it is necessary to carry out the packaging in an environment with a temperature of 22℃-28℃ and a humidity of less than 0.3%. The specific steps of the packaging method include:

[0040] Step S1: Lay the outer aluminum foil bag 3, install the steel inner support seat 5 at the bottom of the outer aluminum foil bag 3, and install the lower liners 11 of the two inner liner frames 1 arranged opposite to each other in the front and rear sides of the steel inner support seat 5 respectively;

[0041] Step S2, laying the inner aluminum foil bag 4 between the two lower liners 11;

[0042] Step S3: Place the assembled battery pole coil unit 3 into the inner aluminum foil bag 4. The reel shaft ends extending from both ends of the battery pole coil unit 3 are clamped on the lower clamping grooves 111 of the two lower liners 11. The upper opening of the inner aluminum foil bag 4 is sealed and the inner aluminum foil bag 4 is vacuumed. The battery pole coil unit 3 is located in the vacuumed inner aluminum foil bag 4.

[0043] Step S4: The upper liners 12 of the two liner frames 1 are respectively clamped and installed on the two lower liners 11, and the left and right sides of the two liner frames 1 are locked and positioned by tensioning rods 131, thereby also locking the lower liner 11 of each liner frame 1 with the left and right sides of the corresponding upper liner 12, and forming a positioning groove for positioning the shaft end of the reel between the lower clamping groove 111 of each lower liner 11 and the upper clamping groove 121 of the corresponding upper liner 12;

[0044] Step S5: sealing the upper opening of the outer aluminum foil bag 3 and simultaneously filling the outer aluminum foil bag 3 with air from the packaging site.
