Description

Technical Field

[0001] This utility model belongs to the technical field of lithium battery module production equipment, specifically relating to a battery cell safety stacking device for lithium battery module production. Background Technology

[0002] The structure of a lithium battery module must support, fix, and protect the battery cells, mainly in terms of mechanical strength, electrical performance, thermal performance, and fault handling capabilities. For high-performance battery modules, thermal management solutions have shifted to liquid cooling or phase change materials.

[0003] The following problems exist: In the lithium battery production process, workers must manually remove each lithium battery from the conveyor and carefully place them in the stacking box. As the conveyor belt continuously delivers new lithium batteries, workers must maintain a high level of attention and concentration to ensure that no lithium battery is missed. This manual operation mode is not only inefficient, but also very time-consuming and manpower-intensive. Chinese utility model patent CN118970141B discloses an adjustable battery module stacking device and its usage method. By setting a module guiding component inside the guide groove, it prevents damage to the two sets of battery cells from collisions during natural falling placement, ensuring the aligned installation of the cells. A discharge groove is opened on the inner top of the guide groove. When the battery modules are aligned, the module guiding component stops working, and the positioning drive lever and storage lever drive related components to press and limit the outer end of the battery module, preventing positional deviation. By driving the threaded rod to rotate via an adjustable motor, the horizontal distance between the two sets of battery module stacking racks can be adjusted according to the battery module specifications, ensuring that the battery modules are placed tightly and safely within the stacking rack. An electric flipping seat operates after the battery modules are stacked, realizing automatic flipping and unloading, improving production efficiency and reducing errors and mistakes caused by human factors. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide a safe stacking device for battery cells used in the production of lithium battery modules.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery cell safety stacking device for lithium battery module production, comprising a conveyor belt, wherein multiple sets of limiting plates are fixedly connected to the outer wall of the conveyor belt, and lithium battery modules are placed between adjacent sets of limiting plates. A stacking mechanism is installed on one side of the conveyor belt, and a chassis is placed on the other side of the conveyor belt. An electric telescopic rod is fixedly connected to the top of the chassis, and a push plate is fixedly connected to the movable end of the electric telescopic rod. A starting mechanism is provided on the push plate. The starting mechanism contacts the limiting plate to open the push switch inside, and the push switch controls the electric telescopic rod to extend and push the lithium battery modules into the stacking mechanism.

[0006] Preferably, the stacking mechanism includes a stacking box and a storage box disposed at the bottom of the stacking box. The bottom surface of the stacking box is provided with a feeding port, and the interior of the storage box is provided with a plurality of placement slots. The opening of the placement slots is directly opposite the feeding port, and the opening size of the placement slots is larger than the opening size of the feeding port.

[0007] Preferably, a sliding frame extends to both sides of the bottom plate of the stacking box, and a vertical rod is provided inside the sliding frame. A spring is sleeved on the vertical rod. A hollow sliding plate is provided on the top plate of the storage box. The vertical rod passes through the hollow sliding plate and is vertically and movably connected to it. The hollow sliding plate moves back and forth along the vertical rod in the sliding frame.

[0008] Preferably, the starting mechanism includes a push switch, a fixed plate connected to the push switch via a pad, a push spring fixedly connected to one outer wall of the pad, a shaft fixedly connected to the upper end face of the fixed plate, a pressure rod rotatably connected to the outer wall of the shaft, and one end of the outer wall of the pressure rod contacting the top of the push spring.

[0009] Preferably, the push switch of the starting mechanism is located at one end of the outer wall of the chassis, and a fixing plate is fixedly connected to the other end of the outer wall of the chassis. A pad is fixed on the opposite side of the push switch and the fixing plate.

[0010] Preferably, one end of the pressure rod extends out and contacts the limiting plate on the conveyor belt.

[0011] Preferably, the electric telescopic rod is aligned with the feed inlet on the bottom surface of the stacking box in the stacking mechanism.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) Automation is achieved by using a mechanical structure. When the limiting plate collides with the pressure rod, the pressure rod will rotate rapidly around the shaft. At this time, one end of the pressure rod will press against the push switch, and the electric telescopic rod will start immediately. The push plate will push the lithium battery module into the feed port. When the limiting plate is disengaged from the pressure rod, the push spring will immediately reset the pressure rod. At this time, the electric telescopic rod will close, and the push plate will quickly reset. This structure not only reduces manpower and time, but also improves the production efficiency of lithium battery modules.

[0014] (2) The lithium battery modules can fall into the placement slot through the feed inlet for stacking. After the placement slot of the storage box is full, the storage box is manually pushed to align the empty placement slot with the feed inlet. After the lithium battery modules in the storage box are stacked, the storage box is manually removed, and the reset spring pushes the hollow slide plate to reset the storage box to the initial position. The slide frame and the hollow slide plate prevent the storage box from shifting when sliding, realizing automatic stacking and saving labor costs. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0021] Example 1, referring to Figures 1-3 The starting mechanism consists of a pressure rod 13, a shaft 12, a push spring 11, and a push switch 8. The pressure rod 13 is hinged to the fixed plate 9 via the shaft 12. One end of the pressure rod extends above the conveyor belt 1 and contacts the side of the limiting plate 2; the other end abuts against the top of the push spring 11, and the other end of the push spring 11 is fixed to the pad 10, which is connected to the push switch 8. When the limiting plate 2 moves with the conveyor belt 1 and collides with the pressure rod 13, the pressure rod 13 rotates clockwise around the shaft 12, and its end presses the push switch 8, triggering the push switch 8 to conduct the circuit and control the electric telescopic rod 6 to start. The push plate 7 then pushes the lithium battery module 3 into the feed port 43. When the limiting plate 2 disengages from the pressure rod 13, the push spring 11 releases its elastic potential energy, pushing the pressure rod 13 to reset counterclockwise. The push switch 8 is disconnected, the electric telescopic rod 6 is closed, and the push plate 7 quickly resets. This structure not only reduces manpower and time but also improves the production efficiency of lithium battery modules.

[0022] The mechanical linkage between the limiting plate 2 and the pressure rod 13 enables precise control of the electric telescopic rod 6, allowing the lithium battery module 3 to be pushed and triggered without manual intervention, thus avoiding delays and errors caused by manual operation. The push spring 11 ensures that the pressure rod 13 immediately resets after the limiting plate 2 disengages, preparing for the next trigger and ensuring a stable response during continuous operation of the conveyor belt 1. The push switch 8 is hidden on the side of the housing 5, preventing interference from external dust, liquids, etc., and improving the reliability of the control mechanism.

[0023] Example 2, refer to Figures 1-3 The stacking mechanism 4 includes a stacking box 41 and a storage box 44, which are connected by a sliding frame 42, a vertical rod 48, a return spring 49, and a hollow sliding plate 46. The bottom surface of the stacking box 41 has a feed inlet 43, aligned with the central axis of the electric telescopic rod 6 and the push plate 7. The hollow sliding plate 46 on the top of the storage box 44 is fitted onto the vertical rod 48 and can slide back and forth along the vertical rod 48. The return spring 49 is fitted onto the vertical rod 48, with its two ends abutting against the sliding frame 42 and the hollow sliding plate 46, respectively. The storage box 44 has multiple layers of placement slots 45 inside, with the opening of each layer of placement slot 45 facing the feed inlet 43, and the opening size being larger than the feed inlet 43 to ensure automatic alignment when the lithium battery module 3 falls in. When the lithium battery module 3 is pushed into the stacking box 41 by the pusher plate 7 and falls into the bottom placement slot 45 through the feed port 43 for stacking, the storage box is manually moved to align the empty placement slot 45 with the feed port to receive the battery modules. After the lithium battery modules 3 in the storage box 44 are stacked, the storage box 44 is manually removed, and the return spring 49 pushes the hollow slide plate 46 to move the storage box 44 back to its initial position. The guide structure of the slide frame 42 and the hollow slide plate 46 prevents the storage box 44 from shifting when sliding.

[0024] Example 3: A safe stacking device for lithium battery modules includes a conveyor belt 1. Multiple sets of limiting plates 2 are fixedly connected to the outer wall of the conveyor belt 1. Lithium battery modules 3 are placed between adjacent sets of limiting plates 2. The conveyor belt 1 transports the lithium battery modules 3, and the limiting plates 2 separate each set of lithium battery modules 3, preventing collisions and facilitating their retrieval. The conveyor belt 1 moves the lithium battery modules 3, and the adjacent limiting plates 2 separate and position them. When a limiting plate 2 moves with the conveyor belt 1 to one side of the housing 5, its side impacts a pressure rod 13. The pressure rod 13 rotates around a shaft 12 and presses a switch 8, activating an electric telescopic rod 6. A pusher plate 7 pushes the lithium battery modules 3 forward. The lithium battery modules 3 are pushed by the pusher plate 7 into the inlet 43 of the stacking box 41 along a straight line, and fall into the bottom placement slot 45 of the storage box 44 due to gravity. After the placement slots of storage box 44 are full, the storage box 44 is manually pushed to align the empty placement slots with the feed inlet. Once the lithium battery modules 3 inside storage box 44 are stacked, storage box 44 is manually removed, and the return spring 49 pushes the hollow slide plate 46 to return storage box 44 to its initial position. The guiding structure of the slide frame 42 and the hollow slide plate 46 prevents the storage box 44 from shifting during sliding. This utility model achieves fully mechanized operation of the lithium battery modules 3 from conveying, triggering, pushing to automatic stacking through the coordinated action of the starting mechanism and the stacking mechanism. Compared with traditional manual stacking, this device significantly improves production efficiency and reduces labor costs. At the same time, through mechanical limit and automatic alignment design, it avoids collisions and misalignments of lithium battery modules 3 during stacking, ensuring production safety and stability.
