A pole piece forming system

Abstract

The invention discloses a pole piece molding system. The pole piece molding system comprises a slicing system and a discharging system; the discharging system comprises a conveying device, a substrate, a horizontal sliding plate and a conveying support frame; the conveying device is arranged on the conveying support frame; the horizontal sliding plate is slidably arranged on the substrate; the conveying support frame is slidably arranged on the horizontal sliding plate; the slicing system comprises a power source and a punching device; the punching device comprises an upper die and a lower die; the power source is used for driving the upper die to move towards a direction close to or far away from the lower die; the upper die is provided with a punching cutter; the lower die is provided with a storage groove; and the conveying device partially extends into the storage groove. The punching system is used for punching a pole piece by one time; the four sides of the molded pole piece are each a circular corner, and sharp corners are not generated, so quality improvement of the pole piece is facilitated; the molded pole piece can be rapidly conveyed out of the slicing system by extending into the conveying device in the storage groove of the punching device so that the punching device can realize slicing again without waiting, and thus the slicing efficiency is greatly improved.

Description

technical field [0001] The invention relates to equipment for making lithium batteries, in particular to a pole piece forming system. Background technique [0002] Lithium power batteries using laminated cells need to cut the pole pieces into a single unit first, and then stack the positive and negative pole pieces in turn. The traditional pole piece forming system uses the retrieving manipulator to grab the formed pole piece. Since the manipulator has many action points in a single cycle during operation, including the manipulator forward-down-rise-back-fall-rise, etc., As a result, the speed of the pole piece forming system is limited within a certain range (≤60pcs / min), which cannot meet the current customer's demand for production output. [0003] For this reason, some manufacturers have developed a pole piece forming system, so that the punching of the mold can match the speed requirements of the pole piece forming system. Type, that is, first cut out the rough shape ...

The traditional pole piece forming system uses the retrieving manipulator to grab the formed pole piece. Since the manipulator has many action points in a single cycle during operation, including the manipulator forward-down-rise-back-fall-rise, etc., As a result, the speed of the pole piece forming system is limited within a certain range (≤60pcs / min), which cannot meet the current customer demand for production output

[0003] For this reason, some manufacturers have developed a pole piece forming system, so that the punching of the mold can match the speed requirements of the pole piece forming system. Type, that is, first cut out the shape blank required by the pole piece, and then cut off the tabs and fillets, so that there are sharp corners around the formed pole piece, which cannot meet the customer's demand for product shape
