TECHNICAL FIELD

[0001] The utility model relates to blister box technical field, concretely relates to a kind of bare cell blister box toughness test gauge. BACKGROUND

[0002] In the production process of soft package battery, bare cell needs to be placed before packaging, which not only ensures the stability of cell structure, facilitates the alignment of aluminum-plastic film packaging, effectively reduces the deviation, ensures the consistency and reliability of packaging quality, improves the yield of product, but also lays a solid foundation for the smooth development of subsequent process. Generally, in order to save cost, the blister box with low price and high automation degree is selected as the bare cell placement optimization. The blister box base material is made of PS material with low cost through blister molding process, and the molding thickness is only 0.6mm. Due to the influence of temperature and other process parameters, the toughness of the blister box is unstable, and the center may be concave in the actual bare cell placement process, which directly affects the bruising of the upper cell blister box to the lower bare cell during the placement process. In order to solve the above problems, the utility model designs a bare cell blister box toughness detection gauge. SUMMARY
