[0002] A lithium battery pack is generally composed of several cells stacked together, which need to be firmly fixed to each other. Manual bundling is currently used, but it is easy to cause skewness, deformation, and excessive deviation in the position and distance of the strapping tape after bundling. A baler is also used for bundling. If the stack of cells is not initially fixed before bundling, the force on the tightening surface of the baler's strap is greater than that on the opposite side, and there is friction between the strap and the end plate. After bundling with the baler, the module will present a fan shape, resulting in deviation in the fixed position of the module, affecting the packaging quality.

After the battery system is assembled, this fixture is used to bundle the modules together, which is labor-saving and quick while greatly reducing labor costs. However, the position of the limit block is fixed, which cannot meet the bundling requirements of various types of battery cells, and the force cannot be controlled when the battery cell is pressed sideways.
