Description

Technical Field

[0001] This invention relates to the field of electric vehicle technology, and more specifically to a blade battery stacking, welding, and hoisting and transporting mechanism. Background Technology

[0002] One of the key technologies for the development of electric vehicles is the power battery. Blade batteries have many advantages, such as good safety performance, light weight, large capacity, low internal resistance and flexible design. They are also gradually developing towards high-rate applications, which better meet the requirements of consumers and have become the mainstream development direction.

[0003] The safety of electric vehicles is one of the most important concerns for consumers. In order to improve the energy density of the battery pack, the design chooses to constrain the length of the module with the box. However, this operation greatly increases the difficulty of the manufacturing process because after the modules are stacked and welded, the poles are subjected to tensile stress when the pressure is released. Therefore, it is necessary to consider that the modules are kept under pressure before entering the box during the production process.

[0004] Therefore, there is an urgent need for a mechanism for stacking, welding, and hoisting and transporting blade batteries. Summary of the Invention

The first screw clamping block and the second screw clamping block are also respectively provided with connecting threaded openings, and the rotating handle is disposed in the connecting threaded openings.

9. The blade battery stacking, welding, and hoisting / transfer mechanism according to any one of claims 2 to 8, characterized in that, The welding pressure head assembly includes a slider connecting plate, a quick clamp, a quick clamp mounting plate, a welding pressure plate, a welding connecting plate, a second guide shaft, a spring bolt, a welding pressure head, a spring, and an oil-free bushing. The oil-free bushing is located below the welding connecting plate and cooperates with the second guide shaft to control the progress of the welding pressure head. The quick clamp is fixed to the welding connecting plate by the quick clamp mounting plate. The push rod of the quick clamp passes through the welding connecting plate and is connected to the welding pressure plate. One end of the second guide shaft is connected to the welding connecting plate, and the other end of the second guide shaft passes through the welding pressure plate and is connected to the oil-free bushing, so that the push rod of the quick clamp can adjust the distance between the welding connecting plate and the welding pressure plate. The welding connecting plate is connected to the slider connecting plate, and the slider connecting plate is connected to the sliding device. The welding pressure plate and the welding pressure head are connected by the spring bolt, and the spring bolt is equipped with a spring. Tightening the spring bolt can control the tightness of the welding pressure head.
