A device for flattening a battery cell electrode tab is provided, which includes a frame, a battery cell clamping mechanism provided on the frame, and a flattening unit provided on two sides of the battery cell clamping mechanism. The present disclosure can adjust an angle and position of a flattening component, which can adapt to different electrode tabs of an inner ring and outer ring of a battery cell coil and different sizes of the battery cell coil. It is more flexible to use, has better a forming effect for the electrode tab, wider application range, and more convenient to operate and adjust, thereby effectively improving a processing and forming efficiency of the electrode tab.

Disclosed in the present invention is a laser cutting apparatus using gas suspension. The laser cutting apparatus using gas suspension in the present invention comprises a laser cutting gas-suspension mechanism and a cutting jig. The laser cutting gas-suspension mechanism comprises a suspension gas cavity, wherein the top of the suspension gas cavity is provided with a gas suspension portion, and at least the part of the top of the suspension gas cavity corresponding to the gas suspension portion is made of a gas-permeable steel; gas filled in the suspension gas cavity can pass through the gas-permeable steel to generate balanced thrust on an electrode plate positioned on a surface of the gas suspension portion, such that the electrode plate can stably suspend in the air; and the cutting jig is arranged outside a side of the suspension gas cavity. The laser cutting apparatus using gas suspension can realize rapid and efficient laser cutting on an electrode plate. The laser cutting apparatus using gas suspension in the present invention is provided with a purging and cleaning module, by means of which dust generated by laser cutting can be directionally purged off, thereby facilitating efficient removing and collecting of dust.

A battery cell tab leveling device, comprising a rack (100), a battery cell clamping mechanism (40) arranged on the rack (100), and kneading units (101) respectively arranged on two sides of the battery cell clamping mechanism (40). Each kneading unit (101) comprises a guide rail (15), a sliding support (14), a kneading mechanism, a first driving mechanism (10) for driving the sliding support (14) to move along the guide rail (15) close to or away from the battery cell clamping mechanism (4), a second driving mechanism (20) for driving a rotating shaft (111) to rotate to drive the kneading mechanism to rotate, and a third driving mechanism (30) for driving a sliding sleeve (121) to move along the rotating shaft (111) to adjust an angle of the kneading mechanism. The battery cell tab kneading device is adaptable to different tabs of inner and outer rings of a jelly roll, and different sizes of jelly rolls.
