[0027] like Figure 1 The battery electrode coil storage and transportation package shown in the figure includes a chassis 1, a box shell 2 covering the chassis 1, and a battery electrode coil packaging group. The battery electrode coil packaging group is placed on the chassis 1, and the box shell 2 covers the battery electrode coil packaging group. The battery electrode coil packaging group is arranged between the chassis 1 and the box shell 2.

[0028] As attached Figure 1 、 2 As shown, in this embodiment, the chassis 1 includes a steel bottom tray 11 and a blister tray 12 laid on the steel bottom tray 11 .

[0029] like Figure 2 As shown, the battery pole coil packaging assembly includes an outer aluminum foil bag 3 with a sealed cavity wrapped in the outermost layer. The outer aluminum foil bag 3 is placed on a blister tray 12. The cavity of the outer aluminum foil bag 3 is filled with air at a temperature of 22°C-28°C and a humidity of less than 0.3%. The outer aluminum foil bag 3 is equipped with a pressure gauge for detecting the air pressure in the cavity and a temperature and humidity measurement label for measuring the temperature and humidity in the cavity. The battery pole coil packaging assembly also includes a battery pole reel support with inner liner frames 4 on the front and rear sides of the outer aluminum foil bag 3, and a battery pole coil unit 5. The battery pole coil unit 5 is embedded in a vacuum inner aluminum foil bag 6, and its axial ends are embedded between the front and rear inner liner frames 4.

[0030] like Figure 3As shown, the battery pole winding unit 5 includes a winding shaft 51 with a boss in the middle for winding an electrode coil 52, an electrode coil 52 wound layer by layer on the boss of the winding shaft 51, a PVC film layer 53 wrapped on the outermost surface of the electrode coil 52 and positioned by tape, two baffles 54 respectively sleeved on the winding shaft 51 and located at both ends of the electrode coil 52, a plastic tube 55 sleeved on the baffle 54 and the PVC film layer 53, and two plastic tubes 55 respectively sleeved and clamped on the winding shaft 51 and located outside the corresponding baffles 54. The blister disk 56 on the side wraps the electrode coil 52 in place through the PVC film layer 53 to prevent it from spreading. Baffles are set at both ends of the electrode coil 52, and a plastic tube 55 is set on the outer side, so that during the packaging process, external collisions will not affect the internal coil. In particular, when the inner aluminum foil bag is set on the outer side of the subsequent packaging and the inner aluminum foil bag is vacuumed, the blister disk 56 and plastic tube 55 at the outermost ends provide good protection for the internal electrode coil, avoiding extrusion and collision caused by the compression of the vacuum space.

[0031] Regarding the battery pole reel support, in this embodiment, as Figure 4 、 5 As shown in , 6, the battery pole reel support includes a steel inner support frame 7 arranged at the bottom of the outer aluminum foil bag 3, and two inner lining frames 4 symmetrically arranged on the front and back sides of the steel inner support frame 7. The steel inner support frame 7 is clamped between the shapes on the blister plate 12 of the chassis 1 through the bottom layer of the outer aluminum foil bag 3.

[0032] Each liner frame 4 includes a lower liner 41 located at the bottom, an upper liner 42 that can be detachably connected to the lower liner 41, and a locking mechanism 43 that can lock the upper and lower liners.

[0033] A lower card slot 411 opening upward is provided in the middle of the upper surface of the lower lining 41, and an upper card slot 421 opening downward is provided on the lower surface of the upper lining 42. When the lower lining 41 and the upper lining 42 are connected, a positioning card slot for positioning the shaft end of the reel 51 is formed between the lower card slot 411 and the upper card slot 421.

[0034] In order to ensure that the liner frame 4 can not only sufficiently support the weight of the battery pole coil unit, but also play the role of buffering, shock absorption, limiting and stabilizing during its transportation, in this embodiment, as shown in FIG. Figure 5 As shown, each lower liner 41 includes a lower liner plastic shell 412 made of EPP plastic, a load-bearing lower steel support 413 embedded in the lower liner plastic shell 412, and a slot support corresponding to the lower card slot 411 on the load-bearing lower steel support 413. Figure 6As shown, each upper liner 42 includes an upper liner plastic shell 422 made of EPP plastic and a load-bearing upper steel support 423 embedded in the upper liner plastic shell 422. The rods extending upward from the front and rear corners of the steel inner support frame 7 are respectively inserted and matched with the corresponding load-bearing lower steel support 413.

[0035] Regarding the locking mechanism 43, the stressed lower steel support 413 extends in the left-right direction and extends out of the upper portion of the lower inner plastic shell 412 to form two lower locking ears, and the stressed upper steel support 423 extends in the left-right direction and extends out of the lower portion of the upper inner plastic shell 422 to form two upper locking ears. The locking mechanism 43 is arranged between the upper locking ear and the corresponding lower locking ear on each side. In this embodiment, Figure 2 、 4 As shown, the locking mechanism 43 includes two tensioning rods 431 located on the left and right sides, and each tensioning rod 431 is respectively passed through the upper locking ear and the lower locking ear of the two liner frames 4 in sequence, thereby locking the upper lining 42 and the lower lining 41 of each liner frame 4, and also locking the front and rear liner frames 4, thereby preventing the two liner frames 4 from twisting due to force vibration during transportation.

[0036] In this embodiment, the upper surface of the lower lining 41 and the lower surface of the upper lining 42 both have positioning grooves and positioning protrusions. When the lower lining 41 and the upper lining 42 are connected, the lower surface of the upper lining 42 and the upper surface of the lower lining 41 are plugged into each other through the positioning protrusions and the positioning grooves.

[0037] In addition, the battery pole reel support may also adopt other structures, for example, including a steel inner support and a steel liner frame whose two lower ends are pivotally connected to the steel inner support. Similarly, each steel liner frame also includes a lower liner and an upper liner that can be split up and down, and the two steel liner frames can be folded toward each other relative to the steel inner support.

[0038] The box shell 2 includes a first U-shaped paper panel 21 and a second U-shaped paper panel 22 which are arranged outside the outer aluminum foil bag 3 in the front and rear directions, and a paper cover 23 which is covered on the upper part of the first U-shaped paper panel 21 and the second U-shaped paper panel 22. The left and right side panels of the first U-shaped paper panel 21 and the left and right side panels of the second U-shaped paper panel 22 are overlapped in pairs, and the overlapping part strengthens the packaging strength in the left and right directions. Combined with the front and rear two inner lining frames 4, the battery pole coil unit is protected by high-strength packaging on all sides. The lower edges of the first U-shaped paper panel 21 and the second U-shaped paper panel 22 are respectively clamped between the blister plate 12 and the edge of the steel bottom tray 11.
