[0002] Conductive metal film is a polymer material with copper or aluminum layers plated on the top and bottom surfaces of substrates such as PET and PP. It has a sandwich structure and is also called a composite thin film current collector. It is a type of material with many good properties and is widely used in lithium-ion batteries, mainly as a battery current collector in lithium-ion batteries.

[0003] When the existing conductive metal film is produced by vacuum coating technology, the evaporated coating material is mainly contained in a high temperature resistant container such as an evaporation crucible to implement the coating of the nano film. Usually, after the effective coating operation is completed, there is still residual evaporated material inside the evaporation crucible, especially the related metal material is easily oxidized in a high temperature environment.

[0004] In order to avoid the above situation as much as possible, the prior art usually requires workers to wrap the evaporation crucible with residual temperature by hand with pearl cotton. However, the temperature of the evaporation crucible at this time is much higher than room temperature, so the workers' operation efficiency is low. In addition, the wrapped evaporation crucibles can only be simply stacked and placed, and the number of evaporation crucibles is large, resulting in a large space being occupied, affecting the normal development of other on-site work.

[0005] The above defects need to be solved urgently. Utility Model Content

In addition, the flexible material of the EPE fixing layer 12 is resistant to high temperatures, which can prevent the evaporation crucible from being bumped, and can also keep the evaporation crucible warm.

[0033] like Figure 2 , Figure 3 As shown, in this embodiment, the top of the storage box 1 is provided with a mounting groove 14, the mounting groove 14 is connected to the accommodating chamber 11, and the bottom of the storage box 1 is protruded outward to form a storage box bottom cover 15. When two or more storage boxes 1 are placed together, the storage box bottom cover 15 of the storage box 1 located at the top is installed in the mounting groove 14 of the storage box 1 located at the bottom, and the storage box bottom cover 15 of the storage box 1 located at the top is located directly above the accommodating chamber 11 of the storage box 1 located at the bottom, that is, the storage box bottom cover 15 of the storage box 1 located at the top and the accommodating chamber 11 of the storage box 1 located at the bottom form a sealed space, thereby preventing the remaining evaporation material in the evaporation crucible from being oxidized. In addition, several storage boxes 1 are stacked in sequence, and the opening of the storage box 1 located at the top is covered with a storage box cover plate 2, which can form a sealed space for storing the evaporation crucible, and at the same time, it can also improve the space utilization rate and avoid affecting the normal development of other on-site work. In addition, the opposite sides of the storage box 1 are provided with a pick-up and placement groove 19, which is convenient for the staff to carry the storage box 1 and improve work efficiency.

[0034] like Figure 4 As shown, in this embodiment, the width of the installation groove 14 is greater than the width of the accommodating cavity 11, and the length of the installation groove 14 is greater than the length of the accommodating cavity 11, so that the installation groove 14 and the accommodating cavity 11 form an installation position for installing the storage box bottom cover 15, which is convenient for forming a sealed space for storing the evaporation crucible, and at the same time can make the stacked storage boxes 1 more stable and prevent the stacked storage boxes 1 from slipping. In addition, a rubber ring is provided on the outer side of the storage box bottom cover 15, which can not only reduce the bumps when the storage boxes 1 are stacked, but also enhance the airtightness of the accommodating cavity 11, and further prevent the remaining evaporation material in the evaporation crucible from being oxidized.

[0035] like Figure 2 , Figure 4As shown, in this embodiment, the pearl cotton fixed layer 12 matches the shape of the accommodating cavity 11 of the storage box 1 and is filled in the accommodating cavity 11 of the storage box 1. The bottom of the pearl cotton fixed layer 12 contacts the bottom surface of the accommodating cavity 11, and a gap is provided between the top of the pearl cotton fixed layer 12 and the top surface of the accommodating cavity 11. The gap is so set that it can not only avoid the contact between the storage box bottom cover 15 and the evaporation crucible, but also facilitate the gas circulation in the accommodating cavity 11. In addition, the height of the gap is 3mm to 15mm, and the height of the gap can be designed to be any value in the range of 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. The height of the gap can be designed according to actual needs during actual design.

[0036] like Figure 3 , Figure 4 As shown, in this embodiment, the bottom of the storage box cover 2 protrudes outward to form a boss 21. When the storage box cover 2 is covered on the opening of the storage box 1, the boss 21 is arranged in the mounting groove 14 of the storage box 1, and the boss 21 is located directly above the accommodating cavity 11 of the storage box 1 below it, that is, the boss 21 and the accommodating cavity 11 of the storage box 1 below it form a sealed space, thereby preventing the remaining evaporation material in the evaporation crucible from being oxidized. In addition, a rubber ring is provided on the outer side of the boss 21, which can not only reduce the collision between the storage box 1 and the storage box cover 2 when they are stacked, but also enhance the airtightness of the accommodating cavity 11.

[0037] like Figure 1 , Figure 2 As shown, in this embodiment, a cover handle 22 is provided on the top of the storage box cover 2 to facilitate the taking and placing of the storage box cover 2. In addition, the storage box cover 2 can be designed with two handles 22, and the two cover handles 22 are respectively provided on both sides of the top of the storage box cover 2 to facilitate the staff to pick up or put down the storage box cover 2. Of course, in actual design, the number and position of the cover handles 22 can be designed according to actual needs.

In addition, a gas delivery pipe 18 is provided at the bottom of the vertical gas delivery channel 17, and the gas delivery pipe 18 extends out of the vertical gas delivery channel 17, and the gas delivery pipe 18 is inserted into the vertical gas delivery channel 17 of another storage box 1 when the storage boxes 1 are stacked, which can play the role of anti-reverse design and prevent the storage boxes 1 from being turned upside down when they are stacked. In addition, after several storage boxes 1 are stacked, the gas delivery pipe 18 of the storage box 1 at the bottom is connected to the air pump assembly (not shown in the figure), and the air pump assembly performs vacuum treatment on the accommodating chamber 11 through the gas delivery pipe 18, which can isolate the air, especially oxygen, and prevent the remaining evaporation material in the evaporation crucible from being oxidized. Of course, the air pump assembly can also input air into the containing chamber 11 through the air pipe 18 to release the vacuum state, thereby facilitating the removal of the evaporation crucible from the containing chamber 11 .

[0039] When the utility model is in use, the evaporation crucible is first placed on the crucible fixing hole 13 of a storage box 1. After the crucible fixing hole 13 of the storage box 1 is filled with evaporation crucibles, the storage box bottom cover 15 of another empty storage box 1 is installed in the installation groove 14 of the storage box 1 located below, and the cycle is repeated until all the evaporation crucibles are placed in the storage boxes 1, and finally the storage box cover plate 2 is covered on the opening of the uppermost storage box 1.
