In the production process of the battery, no matter the battery clamp is separated from the battery during the processes of charging, packaging, cutting and insulation testing of the battery core; after the battery is clamped and fixed by the clamp, the battery is accurately sent to the corresponding stations through the conveying line; therefore, the positioning of the battery on the jig is very important; the positioning accuracy of the battery on the jig directly influences the processing or detection accuracy of the battery cell. The existing positioning of the battery cell on the jig is characterized in that at least three hole sites are formed on the surface of an aluminum plastic film of the battery cell, then the positioning is detected through mechanical profiling, for example, a profiling pin corresponding to the hole sites of the aluminum plastic film is arranged on the jig, the diameter of the pin is equal to that of the hole sites, the positioning of the battery cell on the jig is realized through inserting the pin into the hole sites, and although the positioning structure can enable the battery cell to be accurately positioned on the jig. However, because plastic-aluminum membrane hole site and pin just match, the manipulator is snatched the electric core and is put into the tool after, and the pin stretches out and draws back and inserts in the plastic-aluminum membrane hole site, and this kind of mechanism that detects can judge whether the electric core skew on the tool, but can not judge the skew direction of electric core, and positioning efficiency is slow after the electric core material loading.
