In recent years, with the continuous development of packaging automation technology and the continuous increase in labor costs, it has become increasingly common to use automatic wrapping machines for product packaging. In actual production, when using an automatic wrapping machine to package certain shell-like products (such as battery housings), the following problems are encountered: First, during the packaging process of shell-like products using an automatic wrapping machine, due to the inherent characteristics of the structural stability of the shell, it is prone to being squeezed and deformed, thus affecting product quality. Second, the packaged products are not easy to transfer, store, load and unload vehicles, etc. in subsequent processes. Third, for products such as battery housings, after coming off the production line, the product temperature is relatively high, the shell strength is low, and the supportability is poor, which is also not conducive to the operation of the automatic wrapping machine and subsequent heat dissipation.

[0019] Referring to Figures 1-3 , the present utility model includes a bottom plate 1 and a partition board 2; four support feet 1-1 are provided on the bottom plate 1, and both the height of the support feet 1-1 and the distance between adjacent support feet 1-1 meet the space required for the forklift fork arms to enter and exit below the bottom plate 1; 5-7 layers of battery case groups 3 are stacked on the bottom plate 1, and each layer of battery case group 3 includes a plurality of horizontally arranged battery cases, and each layer of battery case group 3 is arranged as a rectangle as a whole; partition boards 2 are provided between adjacent battery case groups 3 and above the uppermost battery case group 3, the partition boards 2 are also rectangles and are larger than the size of the battery case group 3 as a whole; notches 2-1 are provided on the side edges of the partition boards 2, and the pad rod 4 matches the notches 2-1, and the pad rod 4 passes through the notches on each layer of partition boards 2 from top to bottom in sequence; a packaging film is wound around the periphery of the stacked battery case group 3, and the packaging film winds the battery case group 3, the partition boards 2, the pad rod 4 and the bottom plate 1 into one body. The winding of the winding film is only carried out circumferentially around the battery case group.

[0020] The height of the support feet 1-1 needs to meet that the forklift fork arms can be inserted below the bottom plate 1 during forklift shipment, and at the same time, the horizontal dimension between the support feet can also meet the insertion of the fork arms.

[0021] The rectangular size of the partition board 2 meets that after the partition board 2 covers the battery case group 3, the edge of the partition board 2 is exposed by 3-5 cm, and at the same time, the notch 2-1 is exposed outside the outer side wall of the battery case group 3 to enable the pad rod 4 to pass through the notch 2-1 smoothly.

[0022] The above-mentioned notch 2-1 can also be replaced by a through hole, and the through hole matches the outer shape of the pad rod 4. The purpose of using the notch 2-1 in cooperation with the pad rod 4 or the through hole in cooperation with the pad rod 4 is to meet that when the winding film is wound, the tension force of the winding film acts on the pad rod 4 and the partition board 2 to prevent the battery case from being deformed by extrusion..

[0023] The design of the notch 2-1 adopts the following scheme: the notch 2-1 is in the shape of a dovetail; the cushion rod 4 matches the dovetail shape of the notch 2-1. The head of the cushion rod 4 has a taper to facilitate insertion into the notch 2-1. A tail cover 4-1 is provided at the tail of the cushion rod 4. The cross-sectional dimension of the tail cover 4-1 is larger than that of the notch 2-1. The lower end face of the tail cover 4-1 fits against the upper end face of the uppermost partition 2. This scheme can ensure a reliable and stable combination of the notch 2-1 and the cushion rod 4.

[0024] The design of the partition 2 adopts the following scheme: honeycomb holes 2-2 are provided on the partition 2, and criss-cross reinforcing ribs 2-3 are provided on the partition 2.

The initial temperature of the battery casings is relatively high after production. The four corners of the partition 2 are set as rounded corners to facilitate winding film wrapping. The winding film is only wound around the circumference of the battery casing group, and the heat can be quickly dissipated upward through the gap between the honeycomb holes and the battery casing, thereby further preventing the product from deforming under high temperature stress.

[0025] For the convenience of taking the partition 2: grabbing holes 2-4 for the manipulator to grab are also provided on the partition 2, and the number of the grabbing holes 2-4 is 4, which are evenly arranged on the partition 2.

[0026] For the convenience of storing the partition 2: a flange is provided at the edge of the upper end face of the partition 2, and a groove matching the flange is provided at the edge of the lower end face of the partition 2. When multiple partitions 2 are stacked, the flange and the groove are combined, which helps to increase the stability of the stacked partitions 2.

[0027] To further enhance the force stability of the cushion rod 4: a jack 1-2 matching the head of the cushion rod 4 is provided on the bottom plate 1.

[0028] The placement scheme of the batteries in the battery casing group 3 is as follows: in each battery casing group 3, 3-4 battery casings are placed along the length direction of the rectangle formed by the placement of the battery casing group 3, and 5-6 battery casings are placed along the width direction. The length direction of the battery casing is parallel to the length direction of the battery casing group 3. When 3 battery casings are placed in the length direction and 5 battery casings are placed in the width direction in each layer of the battery casing group 3, 15 battery casings can be placed. When 4 battery casings are placed in the length direction and 6 battery casings are placed in the width direction, 24 battery casings can be placed. The number of battery casings placed in a single layer can also be increased or decreased according to the size of a single battery casing, but the overall size of the battery casing group 3 should not be too large or too small. Being too large will cause insufficient strength of the partition 2, and being too small will cause instability after placement and packaging.
