Description

Technical Field

[0001] This utility model relates to the technical field of battery conveying devices, specifically a conveying device for battery production. Background Technology

[0002] In battery pack production lines, assembled battery modules need to be moved between different workstations using various transfer equipment. Currently, the commonly used hand-pushed storage carts or simple shelving systems have several shortcomings: First, insufficient safety. Existing ordinary conveying devices lack safety designs specifically for battery characteristics. Batteries, especially high-energy-density lithium-ion batteries, are extremely sensitive to collisions, vibrations, and static electricity during transportation. Ordinary devices lack effective cushioning mechanisms, easily causing batteries to slide and collide within the casing, resulting in damage to the external structure or internal cells, and even posing a short-circuit risk. Simultaneously, ordinary metal cart bodies easily accumulate static electricity in dry environments, posing a potential hazard of discharge ignition. Secondly, it suffers from poor ease of operation and stability. For example, the "Conveying Device for Battery PACK Production" disclosed in patent publication number CN223237659U uses a drawer-type placement component that can be completely pulled out from the side. However, in practical applications, when carrying multi-layer heavy battery modules, this placement component and its center of gravity will be significantly suspended outside the housing, posing two major risks: first, it places extremely high demands on the strength of the housing connection structure and slide rails, making them prone to damage; second, it can easily cause the entire conveying device to tip over due to the shift in the center of gravity, resulting in significant safety accidents and property damage.

[0003] In view of this, we propose a conveying device for battery production. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying device for battery production to solve the problems mentioned in the background art.

[0005] A battery production conveying device includes a storage box, characterized in that a base is fixedly connected to the bottom of the storage box, casters are installed on the bottom of the base, and a pusher is fixedly connected to one side of the storage box; the storage box has an open side, and a safety door is rotatably connected to the open side via at least one connecting component; an internal support component for supporting batteries is provided inside the storage box; and a first sealing element and a buffer layer are provided around the inner periphery of the safety door.

[0006] Preferably, the inner support assembly includes at least two opposing C-shaped support frames, and a plurality of rollers are rotatably mounted on the horizontal surface of the C-shaped support frames.

[0007] Preferably, a limiting damping block is provided on the inner wall of the closed side of the storage box opposite to the open side, located between the C-shaped support frames.

[0008] Preferably, the storage box is provided with a first locking part, and the safety door is provided with a second locking part that cooperates with the first locking part.

[0009] Preferably, the connecting component is an anti-static hinge, which includes a hinge plate that is fixed to the storage box and the safety door respectively by conductive fasteners, and a rotating shaft connecting the hinge plate.

[0010] Preferably, anti-collision buffer blocks are fixedly provided at the corners of the base.

[0011] Preferably, the storage box and / or safety door are made of conductive material, and conductive paths are provided between the storage box and the base, and between the base and the casters.

[0012] Preferably, the top of the storage box is also provided with an explosion-proof ventilation opening that communicates with the environment.

[0013] Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Multiple buffering and shock absorption for safe and reliable transportation: This utility model employs an internal roller assembly, limiting damping blocks, a buffer layer, and external anti-collision buffer blocks to form a multiple buffer protection system. The rollers prevent hard friction between the battery and the support frame, the buffer layer and damping blocks effectively absorb the impact energy generated by the battery module inside the storage box during movement, and the anti-collision blocks resist external collisions. These designs reduce the vibration and impact experienced by the battery during transportation, preventing battery performance degradation or safety accidents caused by mechanical damage.

[0014] 2. Side-open storage and retrieval, convenient operation and extremely high stability: This utility model adopts a side-open design, allowing the battery module to be directly pushed in or pulled out from the side along the rollers on the C-shaped support frame. This method completely avoids the risk of tipping caused by the outward shift of the center of gravity in traditional drawer-type structures. Regardless of the battery's weight, its center of gravity remains within the projection plane of the casing, ensuring stability and safety during operation. Simultaneously, the roller structure makes pushing and pulling operations extremely effortless and smooth.

[0015] 3. Excellent sealing and expandability: The seals on the safety door fit tightly against the enclosure when closed, forming a relatively sealed space that effectively isolates external dust and protects the cleanliness of the battery products. Furthermore, the integrated explosion-proof ventilation openings provide ventilation and heat dissipation when transporting batteries at risk of gas evolution, enhancing the equipment's safety redundancy and applicability.

[0021] Please see Figure 1-4 This utility model provides a technical solution: A battery production conveying device includes a storage box 1, characterized in that a base 2 is fixedly connected to the bottom of the storage box 1, and casters 3 are installed on the bottom of the base 2; a pusher 4 is fixedly connected to one side of the storage box 1; the storage box 1 has an open side, and a safety door 5 is rotatably connected to the open side via at least one connecting component 6; an internal support assembly for supporting batteries is provided inside the storage box 1; a flexible first seal 51 and a buffer layer 53 are provided on the inner side of the safety door 5; the internal support assembly includes at least two opposing C-shaped support frames 11, and a plurality of rollers 12 are rotatably installed on the horizontal surface of the C-shaped support frames 11; the inner wall of the closed side of the storage box 1 opposite the open side... The storage box 1 is provided with a limiting damping block 13 located between the C-shaped support frames 11. The storage box 1 is provided with a first locking part 14. The safety door 5 is provided with a second locking part 52 that cooperates with the first locking part 14. The connecting component 6 is an anti-static hinge, which includes a hinge plate that is fixed to the storage box 1 and the safety door 5 respectively by conductive fasteners, and a rotating shaft that connects the hinge plate. The corner of the base 2 is fixed with an anti-collision buffer block 21. The storage box 1 and the safety door 5 are made of conductive material, and there are conductive paths between the storage box 1 and the base 2, and between the base 2 and the caster 3. The top of the storage box 1 is also provided with an explosion-proof ventilation port that communicates with the environment.

[0022] It should be explained that one side of the storage box 1 is completely open, serving as the battery access port. The safety door 5 is rotatably connected to the edge of the open side via a connecting assembly 6. The connecting assembly 6 is an anti-static hinge, with its two hinge plates fixed to the storage box 1 and the safety door 5 using stainless steel screws as conductive fasteners. A groove is formed around the inner periphery of the safety door 5, and the first sealing element 51 made of silicone material is embedded in the groove. When the safety door 5 is closed, the first sealing element 51 is compressed, achieving a seal on the door. A male-end first locking part 14 is installed on the side of the storage box 1 opposite to the push bracket 4, and a female-end second locking part 52 is installed at the corresponding position on the safety door 5, achieving reliable locking of the door.

[0023] The storage box 1 is equipped with an internal support assembly to support the battery. This internal support assembly includes several C-shaped support frames 11 arranged opposite each other on the left and right inner side walls of the box. On the horizontal surface of each C-shaped support frame 11, multiple nylon or rubber-coated rollers 12 are mounted at equal intervals via pivots. On the inner wall of the closed side opposite the open side, a cylindrical rubber limiting damping block 13 is fixed between two C-shaped support frames 11 using adhesive. A circular interface is also provided at the top of the storage box 1 as an explosion-proof ventilation opening.

[0024] Understandably, during use, the operator opens the safety door 5 and pushes the battery module laterally into the opening. The bottom edge of the battery module rests on the C-shaped support frames 11 on both sides and slides easily into the housing with the support of the rollers 12 until its end gently abuts against the limiting damping block 13, completing the positioning. Closing the safety door 5 seals the first seal 51, the buffer layer 53 abuts against the other end of the battery module, and the first locking part 14 and the second locking part 52 engage to lock together. The device is moved by pushing it with the pusher 4, and the casters 3 provide flexibility. During movement, the internal rollers 12, buffer layer 53, and damping block 13 buffer vibrations, while the external anti-collision buffer block 21 prevents rigid collisions. Simultaneously, the explosion-proof ventilation opening at the top vents the interior of the device for ventilation and heat dissipation.
