Description

Technical Field

[0001] The utility model relates to the technical field of battery module assembly devices, in particular to a battery module assembly device. Background Art

[0002] A battery module is a battery system composed of multiple electrically connected battery cells, commonly used in applications such as electric vehicles and energy storage systems. Battery modules offer high energy density, high power density, and long life, meeting the high-performance power requirements of modern power electronics. Battery modules come in a variety of shapes, primarily plate-shaped and cylindrical. The storage capacity and application scenarios of batteries of different shapes vary. To maximize the storage capacity and operating life of battery modules, existing battery modules often utilize battery plates. When assembling a battery module, multiple battery plates are stacked horizontally and secured together using retaining rings.

[0003] Battery modules for different devices vary in size. The spacing between the clamping plates on either side of existing battery module assembly devices is difficult to adjust, making it difficult to adjust according to the length of the battery panels. Furthermore, excessive clamping force on the battery panels can damage the panels and pose a risk. It also makes it difficult to stack multiple panels during assembly, resulting in excessive spacing between the panels, which affects the stacking efficiency. To address this issue, a battery module assembly device has been proposed. Two sets of clamping plates with adjustable spacing can clamp battery panels of varying lengths, while also facilitating movement of the clamped panels. Utility Model Content

In this embodiment, the vertical plate of the pressure plate 3 is provided with a side hole 6, and the side hole 6 is arranged along the sliding direction of the side plate 8. One end of the vertical plate of the side plate 8 close to the pressure plate 3 is slidably connected to the side hole 6, and a connecting plate 7 is slidably connected to the side hole 6.

The battery modules can be pressed by the sliding pressure plates. The two groups of pressure plates 3 with adjustable spacing can be conveniently adjusted according to the length of the battery panels and are suitable for battery panels of various specifications. At the same time, the contraction of the piston of the hydraulic cylinder 12 drives the side plates to approach the fixed end of the pressure plate 3, thereby pressing the battery modules. In this process, the battery modules will move relative to the pressure plates, and the wear caused by the relative movement can be reduced by the rotating rollers provided.
