Battery cell lamination mechanism, blade battery production line and blade battery lamination method

The invention belongs to the technical field of battery production, and particularly relates to a battery cell lamination mechanism, a blade battery production line and a blade battery lamination method.The battery cell lamination mechanism is used for transferring the positive electrode sheet and the negative electrode sheet, and comprises a left belt assembly, a left front manipulator, a left secondary alignment assembly, a left lamination manipulator, a lamination assembly, a right lamination manipulator, a right secondary alignment assembly, a right front manipulator and a right belt assembly which are sequentially arranged in the width direction of theelectrode sheet. The left belt assembly and the right belt assembly operate in the length direction of the electrode sheet, and the lamination assembly is located between the left secondary alignment assembly and the right secondary alignment assembly. As the positive electrode sheet moves to the lamination assembly from the left belt assembly in the width
