Abstract
The utility model belongs to the technical field of electronic product auxiliary assembly technique and specifically relates to indicate a fillet cutting die for battery sheet, including upper die base and take off the flitch, still including setting up in the last cutter of upper die base and set up the lower cutter below last cutter, it is equipped with the fillet edge of a knife to go up the cutter, the cutter is equipped with and coordinates the die -cut cooperation edge of a knife with the fillet edge of a knife down. In practical application, with the cooperation edge of a knife department that cutter under was placed to the utmost point ear of pole piece, the cutter die -cut utmost point ear that moves down is gone up in the drive of external drive mechanism, and after the die -cut completion, the front end of utmost point ear is the fillet that corresponds with the fillet edge of a knife. The utility model discloses structural design is simple, and processing, assembly and dismantlement are easy, and compact structure is small, low in production cost. Behind utmost point ear front end die -cut one -tenths fillet, to have avoided effectively in the further processing in later stage, sharp utmost point ear tip very easily fish tail perhaps ripes electric core, has improved the yields of product greatly, has reduced the production cost, and the practicality is strong.
Description
Technical field
The utility model relates to electronic product technical field of auxiliary equipment, refers in particular to a kind of battery pole piece fillet cutting die.
Background technology
Lithium ion battery is the new generation of green high-energy battery of performance brilliance, one of emphasis becoming hi-tech development.Lithium ion battery has following characteristics: high voltage, high power capacity, low consumption, memory-less effect, nuisanceless, volume is little, internal resistance is little, self discharge is few, cycle-index is many.Because of its These characteristics, lithium ion battery is widely used in the numerous civilian and military field of mobile phone, notebook computer, panel computer etc.
The pole piece of lithium battery in process of production, generally form by band material is die-cut, the lug end of die-cut good rear pole piece is sharp right angle, again because the material of lug itself is sheet metal, in the further processing in later stage, sharp lug end very easily scratches or scratches battery core, causes product bad, increase production cost, defect is obvious.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structural design, and easily, compact conformation, volume is little, the battery pole piece fillet cutting die that production cost is low for processing, assembling and dismounting.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of battery pole piece fillet cutting die, comprise upper bolster and stripper plate, also comprise the upper cutter being arranged at upper bolster and the lower cutter be arranged at below upper cutter, described upper cutter is provided with the fillet edge of a knife, and described lower cutter is provided with and coordinates the die-cut cooperation edge of a knife with the fillet edge of a knife.
Wherein, described upper bolster is provided with guide pillar, and this guide column sleeve is provided with spring, and described stripper plate slides and is arranged at guide pillar, and the two ends of spring abut with upper bolster and stripper plate respectively.
Wherein, described upper bolster comprises cope match-plate pattern and is arranged at the fixed cover of this cope match-plate pattern, and the upper end of guide pillar is installed in fixed cover.
Wherein, described stripper plate is provided with the through hole mated with upper cutter, and the bottom of upper cutter is arranged in this through hole.
The beneficial effects of the utility model: in actual applications, the lug of pole piece is placed on the cooperation knife-edge part of lower cutter, external drive mechanism drives upper cutter to move down die-cut lug, die-cut complete after, the front end of lug is the fillet corresponding with the fillet edge of a knife, under the effect of stripper plate, carry out de-material again, namely complete the die-cut of a lug fillet.The utility model structural design is simple, and easily, compact conformation, volume is little, and production cost is low for processing, assembling and dismounting.After lug front end is die-cut into fillet, efficiently avoid in the further processing in later stage, sharp lug end very easily scratches or scratches battery core, substantially increases the yields of product, reduces production cost, practical.
