Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The utility model discloses a packing carton for utmost point ear, as shown in fig. 1 and 2, box body 1 and lid 2 including mutual lock are equipped with a plurality of unit check 3 that are used for placing utmost point ear on the box body 1, and unit check 3 includes strap portion of holding 31 and colloid portion of holding 32, and colloid portion of holding 32 is equipped with two.

The tab is a raw material of a lithium ion polymer battery product, and includes a metal strip 311 and a colloid 321, the metal strip 311 is a rectangular metal sheet, the colloid 321 is a strip-shaped insulating resin film, the colloid is coated on the metal strip 311, extends along the width direction of the metal strip 311, and two end portions of the colloid 321 protrude from two sides of the metal strip 311 in the width direction, and a fixing position of the colloid 321 and the metal strip 311 is shifted toward one end relative to a middle position of the metal strip 311 in the length direction, so that a planar shape of the tab is approximately cross-shaped. When the multi-disc utmost point ear with the range upon range of putting of the same orientation, because the skew of colloid 321 position, can make the multi-disc range upon range of utmost point ear form the mutual butt of colloid 321 between the double-phase adjacent utmost point ear jointly, the mutual butt of strap 311 length direction's one end, the other end is the fan-shaped structure that alternate segregation expandes, as shown in fig. 9, this structure if adopts ordinary square packing carton packing, causes the disorder or mutual extrusion deformation of utmost point ear easily, influences product quality. The event the utility model discloses a packing carton for utmost point ear is through the cell 3 of placing utmost point ear of design on box body 1 for two adjacent utmost point ears can be crisscross putting towards opposite, guarantee the utmost point ear stability when putting the packing, appear in disorder, warp when avoiding utmost point ear storage transportation.

In the present embodiment, the box body 1 is square and includes a top surface 11 and a bottom surface 12 opposite to each other, and the unit cells 3 are recessed from the top surface 11 to the bottom surface 12, so as to accommodate a plurality of tabs in a stacked state. Specifically, cell 3 includes strap portion of holding 31 and colloid portion of holding 32, and colloid portion of holding 32 is equipped with two, along the longitudinal axis symmetric distribution of cell 3 for utmost point ear can be followed horizontal different orientation and put into cell 3 in, make the mode of putting of utmost point ear more various, in order to be applicable to different production demands. Meanwhile, when the tabs are stacked in different orientations in the cells 3 in a staggered manner, as shown in fig. 8, the two ends of the metal strip 311 in the length direction are respectively abutted to the colloid 321 of the adjacent tab, so that the tabs are balanced in stress, and the tabs are kept in a stable state in the cells 3 in the vertical direction and are not easy to scatter.

Since the surface of the tab with the colloid 321 is protruded outward relative to the surface without the colloid 321, in this embodiment, as shown in fig. 3, the bottom surface of the cell 3 is designed to be stepped, and the depth of the recess of the colloid accommodating portion 32 is greater than the depth of the recess of the metal strip accommodating portion 31, so that when the tab is placed in the cell 3 and abutted against the bottom surface of the cell 3, the protruding portion of the colloid 321 relative to the metal strip 311 can be placed in the stepped groove formed by the downward recess of the colloid accommodating portion 32 relative to the metal strip accommodating portion 31, so that the surface of the metal strip 311 without the colloid 321 is abutted against the bottom surface of the metal strip accommodating portion 31, thereby increasing the contact area between the tab and the bottom surface of the cell 3 and improving the support stability when the tab is placed.

In this embodiment, the two sides of the metal strip accommodating portion 31 in the length direction are respectively provided with a taking and placing groove 5, the taking and placing grooves are communicated with the metal strip accommodating portion 31, and when the tabs need to be taken, the single tab or multiple tabs can be taken one by one through the taking and placing grooves 5.

In this embodiment, as shown in fig. 2 and 3, the bottom surface 12 of the box body 1 is provided with a containing groove 121, the box cover 2 can be placed in the containing groove 121, when the tab packaging box of the present invention is opened, the box cover 2 can be placed in the containing groove 121, so as to avoid the box cover 2 from being placed at will and being left.

In this embodiment, as shown in fig. 1, 5 and 6, the box cover 2 is a cuboid whose length and width are slightly smaller than the size of the box body 1, and is inserted into or clamped with the box body 1. When lid 2 and box body 1 buckled mutually, form a step face between lid 2 and the box body 1, joint portion 4 promptly for a packing carton for utmost point ear and another packing carton for utmost point ear can be followed and vertically piled up each other and put, and joint each other, in order to improve space utilization when transporting and storing. Specifically, in the two adjacent packaging boxes for the tab, which are placed longitudinally, the clamping portion 4 of one packaging box for the tab is inserted into the accommodating groove 121 of the other packaging box for the tab, so that clamping is completed.

In order to make the tabs be placed in different orientations in a staggered manner and in the same orientation, in this embodiment, as shown in fig. 4 and 6, the box cover 2 includes an inner surface engaged with the box body 1 and an outer surface opposite to the inner surface, a fixing groove 21 is disposed at a position of the inner surface corresponding to the metal strip accommodating portion 31 of the box body 1, the fixing groove 21 is recessed from the inner surface to the outer surface, and the depth of the recess is gradually reduced, so that the bottom surface of the fixing groove 21 is inclined. When the tabs are placed in the same direction in the cells, the fixing grooves 21 can accommodate a fan-shaped structure formed by stacking a plurality of tabs, so that the tabs are prevented from being extruded by the box cover. As shown in fig. 7, the fixing blocks 6 having a shape matching with the shape of the fixing grooves 21 are disposed in the fixing grooves 21, when the tabs are stacked in the cells 3 in a staggered manner, the surfaces of the tabs are kept horizontal, and the fixing blocks 6 are embedded in the fixing grooves 21, so that when the box cover 2 is fastened to the box body 1, the tabs are attached to the fixing blocks 6 and kept horizontal; when the same orientation of utmost point ear in 3 inside grooves of unit check stacks, the fan-shaped structure is formed jointly to the multi-disc utmost point ear, and the relative top surface 11 of box body 1 of part utmost point ear is outside protrusion, takes out fixed block 6 from fixed slot 21 this moment, and the bulge of utmost point ear is held by fixed slot 21, has avoided the utmost point ear to be taken out by 2 extrusion deformations of lid.
