Problems solved by technology

When the fastening strip is fastened, the fastening strip may not be straightened, especially when the fastening strip is long, the middle part of the fastening strip will be loose, and the fastening degree of the fastening strip directly affects the mechanical properties of the stack
If the stack is not fastened, it may cause the misalignment of the cells, which will affect the electrical performance of the entire battery
At present, the fastening strips are all fastened manually, and the straightening degree of the fastening strips is also manually controlled, without any measures. In this way, it is difficult for the stack to withstand a large number of mechanical tests

Description

technical field [0001] The invention relates to the technical field of thermal batteries, in particular to a fastening strip straightening device for thermal batteries. Background technique [0002] The thermal battery stack mechanism currently used is a fastening frame composed of upper and lower fixing plates and fastening bars. The single batteries are stacked in the fastening frame and fastened by the fastening bars to form a stack. When the fastening strip is fastened, the fastening strip may not be straightened, especially when the fastening strip is long, the middle part of the fastening strip will be loose, and the fastening degree of the fastening strip directly affects the mechanical properties of the stack. If the stack is not fastened, it may cause the misalignment of the cells, which will affect the electrical performance of the entire battery. At present, the fastening strips are all fastened manually, and the straightening degree of the fastening strips is al...
