Description

Technical Field

[0001] This utility model relates to the field of battery cell production, and in particular to a square battery cell stacking and extrusion device. Background Technology

[0002] In the process of stacking and extruding production modules, precise positioning and stable extrusion of battery cells are crucial. However, traditional production methods mainly rely on manual operation in this step, which brings many challenges and shortcomings.

[0003] First, manual stacking of battery cells makes it difficult to guarantee stacking precision and consistency. Due to differences in the skill level and physical condition of operators, problems such as cell misalignment and displacement often occur during the stacking process. This not only affects the neat arrangement of the cells but may also lead to uneven stress during the subsequent extrusion process, thus affecting product quality.

[0004] Secondly, manually extruding battery cells is inefficient and makes it difficult to control the pressure and duration of the extrusion. Extruding battery cells requires applying pressure and maintaining it for a certain time to ensure a tight bond between the cells and dimensional stability. However, manual operation often makes it difficult to accurately control these parameters, resulting in low production efficiency and inconsistent product quality.

[0005] Furthermore, with the increasing demand for automated and intelligent manufacturing in modern industry, traditional manual stacking and extrusion methods are no longer sufficient to meet the requirements of large-scale, high-efficiency production. Therefore, how to develop a device that can automate and precisely complete the stacking and extrusion of battery cells has become an urgent problem to be solved by the industry.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, a square battery cell stacking and extrusion device includes a support platform 1, a bakelite board 2, a cylinder body 3, and a control panel 4. The support platform 1 supports the battery cells and modules and has rolling balls on its surface for easy movement and transfer of the bakelite board 2. The bakelite board 2 is fixed to the support platform 1 and includes a quick clamp 21, a quick tightening clamp 22, a positioning strip 23, and a positioning block 24 for clamping and positioning the battery cells. Cylinder bodies 3 are located at both ends of the support platform 1, and the bakelite board 2 is fixed between the two cylinder bodies 3. A pressure system is connected through the cylinder bodies 3, applying pressure in the negative X-axis direction according to preset parameters. The control panel 4 is used to adjust pressure parameters (such as pressure value, extrusion speed, and time). A positioning baffle 6 is fixed to the support platform 1 to ensure the bakelite board 2 is in the specified position. A pneumatic baffle 5 is also provided on the side of the support platform 1.

[0024] The main base plate (Bakelite board 2) is machined from 20mm thick Bakelite, offering good load-bearing capacity and low cost, and is used to support the module. Quick clamps 21, quick clamping clamps 22, positioning strips 23, and positioning blocks 24 control the module's positioning along the X and Y axes, preventing movement on the Bakelite board. Both positioning strips 23 and positioning blocks 24 have limit grooves; the positioning block 24 has an arc-shaped groove, and the positioning strip 23 has a U-shaped groove. Positioning strips 23 and positioning blocks 24 control the module's dimensions; only after being pressed to the specified size can the end plate fall into the U-shaped groove of the positioning strip 23.

[0025] When the battery cells are evenly placed on the bakelite board 2, end plates are placed on both sides of the X-axis. Then, the pneumatic baffle 5 moves towards the negative Y-axis, so that the battery cells are placed horizontally on the bakelite board 2. After compression, the pneumatic baffle 5 rebounds. The parameters are adjusted through the pressure system operation screen, so that the cylinder 3 compresses towards the negative X-axis according to the parameters. The pressure is applied to the end plates through the cylinder 3, and the end plates evenly distribute the pressure on the battery cells. Finally, the battery cells are compressed into standard, fixed-size modules under the extrusion system.
