Battery cell manufacturing equipment and method thereof, battery and power utilization device

The invention provides battery cell manufacturing equipment and a method thereof, a battery and a power utilization device, the battery cell manufacturing equipment is used for manufacturing a battery cell, the battery cell comprises a pole piece and a diaphragm, and the battery cell manufacturing equipment comprises a winding mechanism used for winding the pole piece and the diaphragm to form the battery cell; and the membrane pasting mechanism is used for pasting the membrane on a preset position of the pole piece and/or the membrane before the pole piece and the membrane are wound, so that a reinforced membrane layer is formed on the pole piece and/or the membrane. In the battery cell manufacturing process, the diaphragm can be attached to the preset position of the pole piece or the diaphragm while the pole piece and the diaphragm are conveyed, the working procedures are reduced, and the battery cell winding efficiency is improved. 本申请提供一种电芯制作设备及其方法、电池和用电装置，该电芯制作设备用于制作电芯，电芯包括极片和隔膜，电芯制作设备包括：卷绕机构，用于对极片和隔膜进行
