Description
Technical Field

Background
The lithium ion battery has the advantages of environmental protection, long cycle life, good multiplying power performance, good safety and reliability performance and the like, and is widely applied to various energy storage products, consumer electronic products and power cell products. At present, under the strong market competition, the requirement of customers on the energy density of lithium ion battery cells is also increasing.
In order to further improve the energy density of the soft-package lithium ion battery, at present, the invention provides a soft-package aluminum-plastic battery with a single-side double-front-edge structure. However, since the soft-pack aluminum-plastic battery case is an aluminum-plastic case (i.e., the case is a layer of aluminum-plastic film), unlike the case of an aluminum-case battery, which is a stamped aluminum case, the exterior of the soft-pack aluminum-plastic battery case needs to be processed to be as close to a desired shape (e.g., a rectangular parallelepiped shape) as possible to match with related electronic products.
At present, shaping treatment is performed on the appearance of the soft-package aluminum-plastic battery with the single-side double-front-edge structure, specifically comprises bending front-edge operation and bending side-edge small-angle operation, the operations are currently realized through manual operation, and fig. 1 and fig. 2 are schematic diagrams of the soft-package aluminum-plastic battery with the single-side double-front-edge structure before and after shaping. In fig. 1 and 2, for a soft-pack aluminum-plastic battery 100, a front edge 21 before shaping is subjected to a vertical upward bending operation to obtain a shaped front edge 31; the first side edge 22 before shaping and the second side edge 23 before shaping are subjected to a small-angle bending operation toward the inside to obtain a shaped first side edge 32 and a shaped second side edge 33.
The front edge 21 before shaping, the first side edge 22 before shaping, and the second side edge 23 before shaping are integrally formed. Of course, the shaped leading edge 31, the shaped first side edge 32 and the shaped second side edge 33 are also an integral body, only the shaped integral body is completed.
However, by adopting a manual operation mode, the defects of poor consistency, poor controllability, low efficiency and the like exist, meanwhile, the problem that sharp angles (namely folded angle sharp points) are easy to generate at the positions of the small side bending angles also exists, the width size of the battery is influenced, and the popularization and the application of the battery with the single-side double-front-edge structure are further influenced.

then, the profiling positioning plate 11 is pushed downward by the battery pressing block 12 in the battery positioning and clamping structure, so that the profiling positioning plate 11 and the bottom plate 16 move downward while the two corner function pieces 42 move downward together;
then, as the bottom plate 16 acts on the guide post 17 and gradually sinks, the front edge folding functional piece 41 gradually exposes upwards through the shaping operation groove 103, and the top surface of the front edge folding functional piece 41 contacts with the bottom surface of the front edge 21 before shaping in the soft-covered aluminum-plastic battery 100, acts on the bottom surface of the front edge 21 before shaping to enable the bottom surface of the front edge 21 before shaping to be folded upwards, and in the process of upwards folding the front edge 21 before shaping, due to the plastic property of the aluminum-plastic film, the front edge 21 before shaping and the front edge 22 before shaping are connected into a whole, and the second side edge 23 before shaping are folded upwards along with the bottom surface of the front edge 21 before shaping, so that natural folding action towards the inner side direction of the soft-covered aluminum-plastic battery 100 is simultaneously carried out, and the first side edge 22 before shaping and the second side edge 23 before shaping form a folding angle trend, namely folding trend of gradually wrapping the end surface (such as the front end surface) of the soft-covered aluminum-plastic battery 100 is formed;
as shown in fig. 6, during the upward bending operation of the front edge 21 before shaping along the direction C shown in fig. 6, the first side edge 22 before shaping and the second side edge 23 before shaping gradually collapse inward as indicated by the arrow directions a and B in fig. 6, and naturally form a tendency of a folding angle, thereby wrapping the end surface of the soft plastic-aluminum battery 100 and forming a smooth transition.
Then, when the bottom surface of the front edge 21 before shaping is folded up to be attached to the end surface of the soft plastic aluminum-clad battery 100 (i.e., folded up to be in place), and after the trend of forming a folded angle by the first side edge 22 before shaping and the second side edge 23 before shaping, the two folded angle functional pieces 42 move downward along the two rail guide blocks 43, are inserted into the gap between the two folded angle functional pieces 42 and the folded front edge functional piece 41, so that the two folded angle functional pieces 42 realize folding action in the inward direction, and simultaneously perform folding angle operation: the first side edge 22 before shaping and the second side edge 23 before shaping, which have formed the corner folding trend, are continuously pressed towards the end face direction of the soft plastic aluminum battery 100 and finally attached to the end face of the soft plastic aluminum battery 100, so that the shaped front edge 31, the shaped first side edge 32 and the shaped second side edge 33 are obtained at the same time, namely the corner folding front edge and the corner folding side edge small-angle operation are completed at the same time.
