Description

Technical Field

[0001] This utility model relates to the field of battery pack equipment, specifically a cell stacking and positioning device in module production. Background Technology

[0002] In recent years, due to the protection of the Earth's environment, the development of new energy sources has become increasingly important globally. my country has also vigorously promoted the new energy industry. With the rapid development of the new energy vehicle and energy storage industries, the demand for power battery cells and energy storage battery cells is increasing daily. Therefore, the convenience, efficiency, and safety of related automated equipment are crucial. Battery cells are an integral part of the power battery assembly process. During power battery production, battery cells need to be positioned so that multiple stacked battery groups can be bundled together using steel straps. The specific bundling method is as follows: first, a support mechanism supports the stacked battery cell assembly; then, a compression mechanism compresses it, causing the battery cell assembly to elastically deform and shrink in volume; next, the upper strapping part applies a steel strap to the upper part of the compressed battery cell assembly, and the lower strapping part applies a steel strap to the lower part, thus automating the strapping process. This method offers high production efficiency and good safety.

[0003] However, when stacking and positioning multiple battery cells, extrusion plates are set on both sides of the multiple battery cells. The two extrusion plates apply pressure to both sides of the multiple battery cells through cylinders. During the pressure application process, since there is no buffer device, when the extrusion plate approaches the battery cell quickly or the pressure suddenly increases, it is easy to generate impact force, which will cause great damage to the internal structure of the battery cell. Moreover, during the use of the module, when subjected to external vibration or impact, the extrusion plates cannot provide buffer, which will also increase the risk of battery cell damage.

[0005] To achieve the above objectives, a cell stacking and positioning device for module production is provided, comprising a positioning base, a stacking platform fixedly disposed on the surface of the positioning base, multiple sets of cell components evenly placed on the surface of the stacking platform, a retaining seat A disposed on one side of the multiple sets of cell components, a retaining seat B disposed on the other side of the multiple sets of cell components, a second positioning clamping assembly fixedly mounted on the left side of the positioning base, and a first positioning clamping assembly fixedly mounted on the right side of the positioning base, the second positioning clamping assembly comprising a base screwed to the surface of the positioning base, a cylinder fixedly disposed on the base, a drive plate fixedly mounted on the output shaft end of the cylinder, a damping column inserted through the drive plate, and a spring sleeved on the outer side of the damping column.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes a first positioning clamping component and a second positioning clamping component working synchronously to compress multiple sets of battery cells, reducing the distance between the battery cells. The lower steel strip positions and stacks the multiple sets of battery cells and the upper parts of clamping seats A and B; the upper steel strip positions and stacks the multiple sets of battery cells and the lower parts of clamping seats A and B.

[0013] 2. This utility model uses the output shaft of a cylinder to drive a drive plate to move laterally. The drive plate, through four sets of damping columns, drives the mounting plate and elastic seat to move laterally. The elastic seat covers the outside of the clamping seat A and compresses the clamping seat A. At this time, the springs are compressed inside the mounting plate and drive plate. Through the setting of four sets of springs, the pressure acting on the clamping seat A can be elastically buffered. It can also buffer the pressure when the elastic seat applies pressure to the battery cell, avoiding damage to the battery cell caused by excessive pressure at any moment.

[0021] Please see Figure 1-6 This utility model provides a battery cell stacking and positioning device for module production, including a positioning base 1, a stacking platform 2 fixedly disposed on the surface of the positioning base 1, multiple sets of battery cell components 4 evenly placed on the surface of the stacking platform 2, a retaining seat A41 disposed on one side of the multiple sets of battery cell components 4, a retaining seat B42 disposed on the other side of the multiple sets of battery cell components 4, a second positioning clamping assembly 6 fixedly installed on the left side of the surface of the positioning base 1, and a first positioning clamping assembly 5 fixedly installed on the right side of the surface of the positioning base 1, the second positioning clamping assembly 6 including a base 69 screwed and fixedly fixed to the surface of the positioning base 1, a cylinder 68 fixedly disposed on the base 69, a drive plate 67 fixedly installed at the end of the output shaft of the cylinder 68, a damping column 66 inserted through the drive plate 67, and a spring 65 sleeved on the outer side of the damping column 66.

[0022] Working Principle: In actual use, the lower steel strip 3 is first fitted onto the outside of the stacking platform 2. At this time, multiple sets of battery cells 4 are neatly arranged on the stacking platform 2. The outer sides of the multiple sets of battery cells 4 are flush. At this time, the first positioning clamping assembly 5 and the second positioning clamping assembly 6 work synchronously to squeeze the multiple sets of battery cells 4, reducing the distance between the battery cells 4. Then, the lower steel strip 3 is moved upward, so that the lower steel strip 3 wraps between the clamping seat A41 and the clamping seat B42. The clamping seats A41 and B42 are clamped on both sides of the stacking platform 2 through positioning seats and positioning slots. The outer sides of the clamping seats A41 and B42 are respectively aligned with the stacking platform. The two sides of component 2 are flush. The lower steel strip 3 allows for the positioning and stacking of multiple battery cell components 4, as well as the upper parts of the clamping seats A41 and B42. Simultaneously, the upper steel strip 31 covers the upper outer part of the multiple battery cell components 4, allowing for the positioning and stacking of the lower parts of the clamping seats A41 and B42. This enables rapid positioning, bundling, and binding of the battery cell assembly using the lower and upper steel strips 31. No manual operation is required, making it simple, fast, time-saving, and labor-saving. The first positioning clamping component 5 and the second positioning clamping component 6 operate in the same way; here, only the operation of the second positioning clamping component 6 is described: [Starting...] The external switch of cylinder 68 drives the drive plate 67 to move laterally. The drive plate 67, through four sets of damping columns 66, drives the mounting plate 64 and the elastic seat 61 to move laterally. The elastic seat 61 covers the outside of the clamping seat A41 and compresses it. At this time, the springs 65 are compressed inside the mounting plate 64 and drive plate 67. The four sets of springs 65 provide elastic buffering for the pressure acting on the clamping seat A41; they also buffer the pressure applied to the battery cell by the elastic seat 61, preventing damage from excessive pressure. The elastic buffer assembly can adapt to the shape of the battery cell and... The pressure distribution is automatically adjusted based on hardness. When there are slight size differences or uneven hardness between battery cells, the buffer component can use its own elastic deformation to ensure that the extrusion plate applies relatively uniform pressure to each group of battery cells, ensuring that all battery cells can be stacked tightly and evenly, reducing the problem of inconsistent module performance caused by uneven pressure. The elastic buffer component has a certain degree of self-adaptability for battery cells of different specifications. As long as it is within the elastic range of the elastic component, there is no need to make large-scale adjustments or replacements to the extrusion plate. It can adapt to the stacking and positioning requirements of battery cells of different sizes and shapes within a certain range, improving the versatility and flexibility of the equipment and reducing production costs.
