Problems solved by technology

However, the shape of the pole piece produced by this structure is single, and the mold needs to be replaced to produce pole pieces of different sizes. The mold production cost is high and the processing is difficult. Moreover, the equipment has no mechanical structure connection with the subsequent lamination equipment, which reduces the production efficiency.

Abstract

The present invention discloses an electrode sheet forming machine. The electrode sheet forming machine comprises a support mechanism, an unwinding mechanism, an unwinding rectification mechanism, an unwinding traction mechanism, a tension mechanism, a forming mechanism and a material collecting mechanism. The electrode sheet forming machine is characterized in that: the forming mechanism comprises a chamfer clipping mechanism, a constant length cutting mechanism and an electrode lug punching mechanism, wherein the chamfer clipping mechanism, the constant length cutting mechanism and the electrode lug punching mechanism are sequentially arranged on an electrode sheet belt in an unwinding direction; the chamfer clipping mechanism is provided for carrying out clipping for both sides of the electrode sheet belt to form the chamfer of each single electrode sheet, the constant length cutting mechanism is provided for carrying out constant length cutting for the electrode sheet belt to formthe single electrode sheet, the electrode lug punching mechanism is provided for punching the electrode lug of the single electrode sheet. Compare to the prior art, with the present invention, the die cost is saved.

Description

technical field [0001] The invention relates to a manufacturing process of battery pole pieces, in particular to a pole piece forming machine. Background technique [0002] With the widespread application of lithium battery lamination equipment, the requirements for the pole pieces required by lithium battery lamination equipment are also getting higher and higher. At present, the pole piece forming equipment adopts a one-time cutting and forming structure. After the pole piece is cut and formed, the pole piece is manually put into the storage box of the stacking equipment, such as the pole piece automatic forming machine disclosed in Chinese patent CN201699081U , including an unwinding mechanism, a tension mechanism, a feeding mechanism, a forming mechanism, and a side material winding mechanism. The equipment adopts a one-time forming mechanism, which is suitable for automatic production of high-thickness materials such as power battery pole pieces. However, the shape of ...
