Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lithium-ion battery production equipment, and more specifically, relates to a lithium-ion battery electrode placement box. Background Technology
[0002] In the manufacturing process of lithium-ion batteries, positive and negative electrode sheets need to be stacked together in a specific order and quantity. Traditional storage methods often use simple plastic trays or cardboard boxes, where stacks of electrode sheets are simply placed on the trays without any defined placement. This results in inconsistent numbers of electrode sheets stored in the same box. If more electrode sheets are simply packed in, the gaps between them become too small, making it difficult to retrieve them. Even after the electrode sheets are stacked to the correct quantity, during transportation, stacks of electrode sheets may tip over, causing friction and collisions between them. This can lead to bending and contamination of the electrode sheets. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a lithium-ion battery electrode placement box. This placement box consists of an outer box and an inner box. Placing the inner box, after storing the electrodes, inside the outer box ensures the proper placement of the inner box and prevents the electrodes from shifting, effectively protecting the flatness of the electrodes. Furthermore, the shape of the inner box also defines the placement position of the electrodes after they are placed inside, and the first opening allows for easy access and placement of the electrodes, achieving standardized storage of the electrodes.
[0004] To achieve the above objectives, this utility model provides a lithium-ion battery electrode placement box, comprising:
[0005] The outer box has multiple inner box placement cavities inside;
[0006] The inner box body is designed to fit the shape of the cavity in which the inner box body is placed. The inner box body has a first opening in its wall. The shape of the inner box body is designed to fit the shape of the outer periphery of the electrode sheet.
[0007] Optionally, a positioning block is provided inside the inner box, and the positioning block is in contact with the outer surface of the electrode.
[0008] Optionally, the positioning block is fitted and fixed to one of the inner corners of the inner box.
[0009] Optionally, the positioning block is made of rubber.
[0010] Optionally, the first opening is provided in multiple ways on the two side walls of the inner box.
[0011] Optionally, the bottom of the first opening extends to the bottom wall of the inner box.
[0012] Optionally, a handle is provided on the outer side of the inner box, and a second opening is provided on the cavity wall of the inner box placement cavity, with the handle corresponding to the position of the second opening.
[0013] Optionally, handles are provided at both ends of the outer side of the inner box. The handles are U-shaped. When the inner box is placed in the inner box placement cavity, the handles pass through the second opening and extend to the outside of the outer box.
[0014] Optionally, the second opening is centrally located on the cavity wall of the inner box placement cavity, and a flange is provided between the second opening and the bottom wall of the inner box placement cavity.
[0015] Optionally, the outer box body has multiple partitions inside, which divide the interior of the outer box body into multiple inner box placement cavities.
[0016] This utility model provides a lithium-ion battery electrode placement box, which has the following advantages:
[0017] 1. The electrode placement box uses partitions to divide the interior of the outer box into multiple independent storage spaces, effectively preventing friction and contamination between stacks of electrodes and protecting the electrodes from damage;

[0027] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0028] This utility model provides a lithium-ion battery electrode placement box, comprising:
[0029] The outer box has multiple inner box placement cavities inside;
[0030] The inner box body is shaped to match the cavity inside the inner box body. The inner box body has a first opening in its wall. The shape inside the inner box body matches the shape of the outer periphery of the electrode sheet.
[0031] Specifically, the placement box includes an outer box and multiple inner boxes. The inner boxes are placed in the placement cavities of the inner boxes. Since the shape of the placement cavity matches the shape of the inner box, the placement position of the inner box in the outer box can be defined. In addition, the shape inside the inner box matches the shape of the outer periphery of the electrode. Thus, when the electrode is placed in the inner box, there is only one way to place the electrode, and the electrode can only be arranged one on top of another, avoiding the electrode from moving in the placement box and thus avoiding the problem of electrode collision, damage or bending.
[0032] Optionally, a positioning block is provided inside the inner box, and the positioning block is in contact with the outer surface of the electrode.
[0033] Optionally, the positioning block is fitted and fixed to one of the inside corners of the inner box.
[0034] Optionally, the positioning block is made of rubber.
[0035] Specifically, a rubber positioning block is set in a corner inside the inner box, so that the edge of the electrode can be engaged with the edge of the positioning block, which limits the way the electrode is placed in the inner box.
[0036] The inner and outer boxes of the placement box can be fitted with lids. After the electrodes are placed in the inner box, the lid of the inner box can be closed to ensure that the electrodes in the inner box will not be covered in dust or easily blown away. After all the inner boxes are placed in the outer box, the lid of the outer box can be closed to prevent the inner boxes from falling out of the outer box, thus ensuring the sealing and stability of the placement box during transportation.
[0037] Optionally, multiple first openings are provided on the two side walls of the inner box.
[0038] Optionally, the bottom of the first opening extends to the bottom wall of the inner box.
[0039] Specifically, multiple first openings are provided on the two side walls of the box. When taking the electrode from the inner box, the fingers can contact the edge of the electrode through the first opening, making it convenient to take the electrode. In addition, the bottom of the first opening extends to the bottom wall of the inner box, so when taking the bottom electrode of the inner box, the edge of the electrode can also be contacted through the first opening.
[0040] Optionally, a handle is provided on the outside of the inner box, and a second opening is provided on the cavity wall of the inner box placement cavity, with the handle corresponding to the position of the second opening.
[0041] Optionally, handles are provided at both ends of the outer side of the inner box. The handles are U-shaped. When the inner box is placed in the inner box placement cavity, the handles pass through the second opening and extend to the outside of the outer box.
[0042] Specifically, a handle is provided on the outside of the inner box, and a second opening is provided on the cavity wall of the inner box. When the inner box is placed in the inner box cavity, the handle is located in the second opening. When it is necessary to take out a stack of electrodes from the outer box, it is not necessary to transfer the electrodes out one by one; the entire inner box can be taken out directly. The handle is located on the outer sides of both ends of the inner box, so that the handle and the first opening do not interfere with each other. When the inner box is placed in the outer box, the handle is in an inverted U-shape, and the handle extends from the inner box cavity to the outside of the outer box through the second opening. The handle can be firmly connected to the inner box through the opening on the lower side, ensuring that the electrodes in the inner box are always placed horizontally when the inner box is removed.
[0043] Optionally, the second opening is centrally located on the cavity wall of the inner box placement cavity, and a flange is provided between the second opening and the bottom wall of the inner box placement cavity.
[0044] Specifically, the second opening is located on the side wall of the outer box. To ensure the overall strength of the outer box, the bottom of the second opening does not extend to the bottom wall of the outer box. Instead, the side walls on both sides of the second opening are connected by a flange. Furthermore, the second opening does not extend to the bottom of the outer box because when the inner box is placed in the inner box cavity, there is space between the handle and the table where the outer box is placed, allowing a hand to easily enter between the handle and the table and lift the inner box steadily from the bottom of the handle.
[0045] Optionally, the interior of the outer box is provided with multiple partitions, which divide the interior of the outer box into multiple inner box placement cavities.
[0046] Specifically, multiple partitions are installed inside the outer box to divide the internal space of the outer box into multiple inner box placement cavities. This ensures the proper placement and position of the inner boxes within the outer box, preventing the inner boxes from shifting during transportation and causing damage to the electrode sheets.
[0047] Example
[0048] like Figures 1 to 3 As shown, this utility model provides a lithium-ion battery electrode placement box, comprising:
[0049] The outer box has 8 compartments, and there are two inner box placement cavities inside.
[0050] The inner box 3 is designed to fit the shape of the inner box placement cavity. The long side wall of the inner box 3 is provided with two first openings 4. The shape of the inner box 3 is designed to fit the shape of the outer periphery of the electrode 5.
[0051] In this embodiment, a positioning block 1 is provided inside the inner box 3, and the positioning block 1 is attached to the outer surface of the electrode 5.
[0052] In this embodiment, the outer surface of the positioning block 1 is in contact with one of the inner corner surfaces of the inner box 3.
[0053] In this embodiment, the positioning block 1 is made of rubber.
[0054] In this embodiment, the bottom of the first opening 4 extends to the bottom wall of the inner box 3.
[0055] In this embodiment, a handle 2 is provided on the wide side wall of the inner box 3, and a second opening 7 is correspondingly provided on the cavity wall of the inner box 3 placement cavity, and the width of the handle 2 corresponds to the width of the second opening 7.
[0056] In this embodiment, the handle 2 is inverted U-shaped. When the inner box 3 is placed in the inner box placement cavity, the handle 2 passes through the second opening 7 and extends to the outside of the outer box 8.
[0057] In this embodiment, the second opening 7 is centrally located on the cavity wall of the inner box placement cavity, and a flange is provided between the second opening 7 and the bottom wall of the inner box placement cavity.
[0058] In this embodiment, a partition 6 is provided inside the outer box 8. The partition 6 is parallel to the wide side of the outer box 8 and divides the interior of the outer box 8 into two inner box placement cavities.
[0059] In summary, the outer box 8 of this electrode placement box can hold two inner boxes 3, and the two inner boxes 3 are fixed in the outer box 8 by the partition 6, ensuring that the inner boxes 3 will not shake in the outer box during transportation. A positioning block 1 is attached and fixed to one of the inside corners of the inner box 3. The positioning block 1 can limit the placement of the electrodes, placing them one by one into the inner box 3. The positioning block 1 is made of rubber and will not damage the electrodes. When an inner box 3 is full of electrodes 5, it is placed into the outer box 8. When it is necessary to take out an electrode 5, the entire stack of electrodes 5 can be taken out of the outer box 8 by first using the handle 2. Then, the fingers can contact the two sides of the electrode through the first opening 4, so that an individual electrode 5 can be taken out from the inner box 3. The whole process will not cause damage or bending to the electrodes and also reduces the difficulty of taking out the electrodes.
[0060] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
