[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0037] Implementation Method 1

[0038] In the existing structure, after the battery is packaged, the top of the battery is still under pressure, causing the battery to bear additional weight, which is not conducive to protecting the battery structure.

[0039] The square battery tray of the utility model comprises a tray body 1; a plurality of grooves 2, which are arranged at equal intervals in the tray body 1, for placing batteries 6; the side of the groove 2 protrudes upward to form a protrusion 20, and the protrusion 20 is arranged along the length direction of the battery 6, and the height of the protrusion 20 is greater than the height of the battery 6, and is used to support the pressure on the top of the battery 6. The utility model optimizes the tray structure and adds the protrusion 20, which is used to withstand the pressure of the bottom 11 of the tray body 1 of the upper layer. The top plane of the protrusion 20 is higher than the top plane of the battery 6, which can offset the deformation of the protrusion 20 after bearing pressure, and helps to prevent the top of the battery 6 from being subjected to pressure. At the same time, multiple tray bodies 1 can be stacked on each other to prevent any part of the battery 6 from being exposed, that is, all of them are wrapped inside the tray body 1, which helps to resist the impact of foreign objects.

[0040] Specifically, the inside of the tray body 1 is designed with an array of grooves at equal intervals in a 5X8 manner to ensure that the spacing between each battery 6 is the same, so as to facilitate the application of automated equipment, and by designing a sinking scheme on both sides of each battery 6, it is used to provide operating space for the gripper of the automatic gripping equipment. When the gripper takes and puts the battery, it provides sufficient space margin to prevent the gripper from hitting the tray body 1. In addition, the material of the top patch on the top of the battery 6 is PP. If a heavy object is pressed on the top patch for a long time, white marks or even white powder will appear on the top patch, resulting in a poor appearance of the battery. The utility model adds a protrusion 20 so that the battery 6 of the tray body 1 is not in contact with the bottom 11 of the tray body 1 on the upper layer, which helps to improve the yield rate of the battery appearance.

[0041] In the square battery tray according to the utility model, a plurality of grooves 2 are arranged at equal intervals on the tray body 1, and the lateral and longitudinal intervals of two adjacent grooves 2 are the same. Specifically, the inside of the tray body 1 is designed with an array of grooves at equal intervals in a 5X8 manner to ensure that the spacing between each battery 6 is the same, so as to facilitate the application of automated equipment. Among them, the tray body 1 has 40 grooves 2, which can hold 40 batteries 6, and the lateral and longitudinal intervals between each groove 2 are the same, which is conducive to the positioning of the mechanical gripper 5 and the automatic grasping of the battery 6.

[0042] In the tray of square batteries according to the utility model, the difference between the length of the groove 2 and the length of the battery 6 is 3mm-5mm, the difference between the width of the groove 2 and the width of the battery 6 is 3mm-5mm, and the difference between the depth of the groove 2 and the height of the battery 6 is 7mm-9mm, which helps the mechanical gripper 5 of the automated equipment to position and automatically grasp the battery.

[0043] In the tray of square batteries according to the utility model, the tray body 1 includes a bottom 11 and a side wall 12, the side wall 12 extends upward from the bottom 11, the side wall 12 surrounds an opening, the side wall 12 protrudes upward to form a convex portion 122, and the lower surface of the bottom 11 is provided with a card slot 121, and the card slot 121 is used to engage with the convex portion 122 of other tray bodies 1. Specifically, the card slot 121 can engage with the convex portion 122 of the side wall 12 of the tray body 1 of the next layer, the card slot 121 is equivalent to the card portion, and the convex portion 122 of the tray body 1 of the next layer is equivalent to the buckle portion, and the two are fixedly connected by card connection, and other tray bodies 1 are also fixed by referring to this card connection method, so that two adjacent tray bodies 1 are mutually engaged, that is, when stacked, the two adjacent tray bodies 1 can be fixed to prevent the tray bodies 1 from shaking in the horizontal direction, thereby reducing the risk caused by shaking during transportation and improving transportation safety.

[0044] In the square battery tray according to the utility model, ventilation holes are arranged around the tray body 1 to ensure air circulation inside and outside.

[0045] In the square battery tray according to the utility model, the material of the tray body 1 is foam. Specifically, the utility model adopts a foam tray, which protects the battery through a full-enclosed structure, and the outer dimensions match the cardboard.

[0046] The working principle of the utility model is:

[0047] The utility model optimizes the tray structure and adds a protrusion 20 to withstand the pressure from the bottom of the tray body 1 of the upper layer. The top plane of the protrusion 20 is higher than the top plane of the battery 6, which can offset the deformation of the protrusion 20 after bearing pressure, and helps to prevent the top of the battery 6 from being subjected to pressure. At the same time, the tray bodies 1 can be stacked on each other to prevent any part of the battery from being exposed, that is, the battery is completely wrapped inside the tray body 1, which helps to resist impact from foreign objects.

[0048] Implementation Method 2

[0049] The difference from the first embodiment is that two protrusions 20 are correspondingly arranged for each groove 2 of this embodiment, and the two protrusions 20 are symmetrically arranged on both sides of the groove 2, which can evenly support the pressure at the bottom of the tray body 1 of the upper layer, and help to avoid pressure on the top of the battery.

[0050] The other structures are the same as those in the first embodiment and will not be described in detail here.

[0051] Implementation Method 3

[0052] The difference from the first embodiment is that the protrusion 20 of this embodiment is a columnar structure, and the top of the columnar structure is an arc-shaped transition, which prevents the top of the columnar structure from scratching the battery 6, and helps to improve the yield rate of the battery.

[0053] The other structures are the same as those in the first embodiment and will not be described in detail here.
