PROCESSING DEVICE AND SHEET PROCESSING METHOD

This application discloses processing equipment (100), electrode plate processing equipment, battery processing equipment, and a sheet processing method. The processing equipment includes a rotation roller (20) and a laser assembly (30). The rotation roller (20) is rotatable around a first axis (L1). An outer peripheral surface of the rotation roller (20) around the first axis (L1) is configured to allow winding of a sheet (200). The outer peripheral surface of the rotation roller (20) is able to move synchronously with the sheet (200) around the first axis (L1). The laser assembly (30) is disposed on the rotation roller (20) and able to rotate with the rotation roller (20). The laser assembly (30) is configured to drive a laser beam (H) to be emitted toward the sheet (200), and further configured to drive the laser beam (H) to move linearly and/or oscillate around a second axis (L2) that intersects the first axis (L1). The foregoing technical solution improves synchronism between the motion of the laser beam (H) and the motion of the sheet (200) to improve precision of laser marking or laser cutting.
