Abstract
One aspect of the present disclosure relates to an auto-splicing device for an electrode and an auto-splicing method, and more particularly, to an auto-splicing device for an electrode and an auto-splicing method, which can minimize connection defects between the running electrode and the new electrode, wherein the running electrode and the new electrode connected and supplied to the running electrode are aligned on the basis of their coating lines by using the auto-slicing device.
Claims8
An auto-splicing device for an electrode, comprising:
- an electrode supply unit;
- a first electrode conveying unit comprising a first unwinding unit which is configured to unwind a first electrode;
- a first conveying unit which is configured to convey the unwound first electrode;
- and a first splicing unit which is configured to connect a second electrode to the first electrode when unwinding of the conveyed first electrode is completed;
- and
- a second electrode conveying unit comprising a second unwinding unit which is configured to unwind the second electrode;
- a second conveying unit which is configured to convey the unwound second electrode;
- and a second splicing unit which is configured to connect the second electrode to the first electrode,
- wherein the first splicing unit or the second splicing unit comprises a first Edge Position Control (EPC) sensor and a second EPC sensor facing side surfaces of the first electrode or the second electrode,
- the first EPC sensor and the second EPC sensor face the same direction to sense one electrode surface of the first electrode and one electrode surface of the second electrode located on the same plane when the first electrode and the second electrode are connected, and
- the first EPC sensor is configured to sense a coating line formed on one electrode surface of the first electrode, and the second EPC sensor is configured to sense a coating line formed on one electrode surface of the second electrode.
