Description

A heavy-load turnover box Technical Field

[0001] The present invention relates to a turnover box, in particular to a turnover box suitable for circulating articles on a full-automatic assembly line and capable of bearing large pressure. Background Art

[0002] New energy vehicles are becoming a vital national industry. After battery cells come off the production line, they are typically assembled at automakers. This requires extensive tool replacement, wasting significant manpower and potentially causing product damage. After they come off the production line, automakers typically store them in warehouses before assembly, stacking them in boxes. These boxes are often poorly designed, with lids often left open. In the event of a fire, the sprinklers can activate, causing water to accumulate inside the boxes. Prolonged immersion in water can affect product quality. Furthermore, the lower boxes are subject to significant pressure, which can lead to damage, potentially damaging the boxes and the product itself. Developing turnover boxes that can withstand strong pressure while preventing water accumulation during spraying became a challenge. Technical issues

[0003] In order to solve the above technical deficiencies, the present invention provides a heavy-duty turnover box with no water accumulation in the box body and high bearing pressure. Technical Solutions

[0004] The present invention discloses a heavy-load turnover box, comprising a box body, with reinforcing beams embedded in the same direction of the bottom wall of the box body, a flat plate fixedly connected to the bottom wall of the box body, the orthographic projection area of ​​the flat plate being smaller than the orthographic projection area formed by the outer side surface of the box body, so that the flat plate cooperates with the inner cavity of the box body, that is, when two boxes of the same size and shape are stacked, the flat plate can be embedded in the other box body and can move in and out freely under the action of external force; the outer side surface of the box body is a flat surface, and a structure for a robot to pick up the box body is provided on the outer side wall of the box body; the side walls of the box body are two walls parallel in the vertical direction and the two walls are connected into one at the top; corresponding through holes are provided on the bottom wall of the box body and the flat plate, so that the liquid in the box body can flow out of the box body through the through holes.

[0005] In order to prevent water accumulation in the heavy-load turnover box, the hole area accounts for 30% of the total area of ​​the bottom wall of the box.

[0006] In order to facilitate assembly line operations and maintain consistent placement order, the heavy-load turnover box has a positioning angle at the four corners of the inner cavity of the box body. The shape of the positioning angle is different from the other three. For example, the other three are right angles and one is a 45-degree chamfer; three can also be rounded corners and one is a 60-degree chamfer, and so on. When the corners of the bottom flat plate of the box body and the inner cavity angle above it are in the same position, the shape must be the same so that the same boxes are in the same orientation when stacked.

[0007] It also includes the lining. The shape and specifications of the lining are different due to the different objects placed in it. The design only needs to ensure that the robot can easily pick it up.

[0008] If it rains during transportation, rainwater from the sides will penetrate into the box. There is a step formed on the outer frame of the upper edge of the box. The height of the outer upper edge is lower than that of the inner side. There is a circle of protrusions extending downward from the outermost side of the bottom of the box. The protrusions cooperate with the steps on the outer frame of the upper edge of the box, so rainwater from the outside will not enter the box.

[0009] Due to the different types of manipulators, the structure on the box for the manipulator to pick up can be a concave or convex design; for the concave part, the manipulator can recognize it and clamp the box by pressing on both sides, and the convex part can be grasped by just putting it on the part or grabbing the part. The concave structure design is more suitable for use and takes up less space; some products are not affected by the performance of magnetic force, and there is also this structure that can fix magnets or magnetic materials on the side wall of the box. The manipulator can realize the magnetic force on the box when the power is on or off. This design completely realizes the flatness of the outer surface.

[0010] In order to improve efficiency, several identical boxes can be stacked on each box.

[0011] In order to effectively flow on the assembly line, the lower surface of the flat plate at the bottom of the box has a roughness, such as the roughness is made into leather grain on the mold, formed by injection molding. Of course, other methods are also possible, and there are some grains on the lower surface of the bottom of the box.

[0012] To protect the goods inside the box from damage during turnover, it can also be equipped with a lid. Since heavy-duty turnover boxes are placed on pallets, after stacking multiple boxes from the bottom up, the top one is equipped with a lid. The lid's lower surface only needs to be flat, and the upper surface can cooperate with the box body to provide rain protection. A circle of protrusions extends downward from the lower surface of the lid, which cooperates with the steps on the upper edge of the outer frame of the box body. When stacking, it is also possible to stack upwards. The upper surface of the lid is provided with a boss, the orthographic projection of which is L-shaped, with the L-shaped bosses all facing outward and symmetrically distributed at the four corners of the lid.

[0013] The material of the box body can be PP, PE, or other plastic materials, and any material that is formed by pressing a mold and can be recycled can be used. Beneficial effects

[0014] According to the above-mentioned heavy-duty turnover box, it has a waterproof function on the side, can leak water during fire fighting, and no water accumulates in the upper box body; there will be no mistakes when stacking, and the upper box body is placed in the specified direction. During mechanized operation, the robot can accurately identify and position it, and the assembly line flow efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments. Example

[0026] In Figures 1 to 4, a heavy-load turnover box includes a box body, and a reinforcing beam 2 is embedded in the same direction of the bottom wall 1 of the box body. A flat plate 3 is welded to the bottom wall 1 of the box body. The orthographic projection area of ​​the flat plate 3 is smaller than the orthographic projection area formed by the outer side surface of the box body. Therefore, the flat plate 3 is matched with the inner cavity of the box body, that is, when two boxes of the same size and shape are stacked, the flat plate 3 can be embedded in the other box body and freely move in and out under the action of external force; the outer side surface of the box body is a flat surface, and a structure 4 for a robot to pick up the box body is provided on the outer side wall of the box body; the structure 4 is a double-layer structure, that is, the side walls of the box body are two walls parallel in the vertical direction and the two walls are connected into one at the top; corresponding through holes 5 are provided on the bottom wall 1 of the box body and the flat plate 3, so that the liquid in the box body can flow out of the box body through the through holes 5; the reinforcing beam 2 is a strip-shaped body made of metal material. The metal material is selected mainly for its high strength. Of course, other materials are also acceptable. As long as it has high compressive strength, replacement is not a problem. Example

[0027] In Figures 5, 6 and 7, the difference from Example 1 is that reinforcing ribs 6 are provided in the vertical direction between the double-layer structure of the side wall of the heavy-load turnover box to improve the bearing capacity of the box, and a step 7 is formed on the outer frame of the upper edge of the box. The height of the outer upper edge is lower than that of the inner side, and a circle of protrusions 9 extends downward from the outermost side of the bottom of the box. The protrusions 9 cooperate with the steps 7 on the outer frame of the upper edge of the box, that is, when several layers are stacked on it, the steps 7 on the outer edge of the box are compressed at the same time. Example

[0028] In Figure 2, what is different from the above embodiment is that: there is a positioning angle at the four corners of the inner cavity of the box, one is a 45-degree angle, and the other three are rounded corners. When the corners of the bottom plate 3 of the box and the inner cavity angle above it are in the same position, one corner on the plate 3 is a 45-degree angle, and the other three are rounded corners, corresponding one to the other.

The orthographic projection area of ​​the flat plate 3 is smaller than the orthographic projection area formed by the outer side surface of the box. Therefore, when two boxes of the same size and shape are stacked, the flat plate 3 can be embedded in the other box and move in and out freely under the action of external force; the outer side surface of the box is a flat surface, and a structure 4 for a robot to pick up the box is provided on the outer side wall of the box; the side walls of the box are two walls parallel in the vertical direction and the two walls are connected into one at the top; corresponding through holes 5 are provided on the bottom wall 1 of the box and the flat plate 3; reinforcing ribs 6 are provided in the vertical direction between the double-layer structure of the side wall of the heavy-load turnover box, and the wall thickness of the side wall The box body has a 3mm thickness, and one of the four corners of the inner cavity has a different shape from the other three, with the other three being right angles and one being a 45-degree angle. When the corners of the bottom plate 3 of the box body are in the same position as the inner cavity angle above it, one angle on the plate 3 is a 45-degree angle, and the other three are right angles, corresponding one to the other. The total thickness of the bottom wall 1 and the plate 3 is 48mm. Four metal strips measuring 30x15mm are embedded longitudinally in the bottom wall 1. The plate 3 is 3mm thick. It also includes a lid 8, with a circle of protrusions 9 extending downward around its lower surface, which cooperate with the steps 7 on the upper edge of the outer frame of the box body. When stacking, it is also possible to stack upwards. A boss 10 is provided on the upper surface of the lid 8. The orthographic projection of the boss 10 is L-shaped, and the L-shaped bosses 10 are all outward, symmetrically distributed at the four corners of the lid 8. The heavy-duty turnover box designed in this way has a dynamic load of 2.2T and a static load of 4.5T.
