[0002] With the continuous advancement of electrochemical battery technology, the technical maturity and economic efficiency of electrochemical battery energy storage power stations have continued to improve, and they have become increasingly popular in the power sector.

[0003] Currently, steel strapping is primarily installed on battery modules manually. During installation, the aluminum plates on either side of the battery module are clamped together using a clamp, and the steel strap is manually applied to the module. When the clamp is released, the battery module compresses, holding the steel strap in place. However, during robotic clamping and transport, the high clamping force of the robot clamp causes the battery module and the aluminum plates to contract, making the steel strap susceptible to falling. This resulting in the need for rework of the battery module, inefficiently. A falling steel strap can also easily cause the module to fall and be damaged, resulting in significant cost savings. Utility Model Content

The lower end of the steel belt clip portion is provided with a first bent portion for clipping the lower edge of the upper fixed steel belt.

[0007] The steel belt clamping portion and the lower fixed steel belt clamping plate are provided with waist-shaped holes, and the steel belt clamping portion and the lower fixed steel belt clamping plate are adjustably connected by a nut fixing assembly;

[0008] A second bent portion is provided at the lower end of the lower fixing steel belt clip plate for clipping the lower edge of the lower fixing steel belt.

[0009] Furthermore, the upper fixed steel belt snap plate and the lower fixed steel belt snap plate are made of metal plates.

[0010] Furthermore, the aluminum plate fixing portion is provided with a groove, and the nuts and bolts are arranged in the groove.

[0011] Furthermore, the bolt is welded to the aluminum plate fixing portion.
