Opening method and opening device

An opening device, comprising:

• a first laser processing apparatus and a second laser processing apparatus;
• the first laser processing apparatus configured to process a first processing area of an object to be opened to form a first opening area on the object to be opened;
• the second laser processing apparatus configured to process a second processing area of the object to be opened to form a second opening area on the object to be opened;
• and
• wherein a power of the first laser processing apparatus is greater than a power of the second laser processing apparatus, a light spot of the first laser processing apparatus is larger than a light spot of the second laser processing apparatus, and the second opening area surrounds at an edge of the first opening area and connects to the first opening area;
• the first laser processing apparatus comprises a first laser transmitter, a plurality of first galvanometer systems and a first driving unit;
• each of the plurality of first galvanometer systems is configured to transmit a laser emitted by the first laser transmitter to different areas of the object to be opened, so that the first laser processing apparatus simultaneously processes a plurality of first processing areas of the object to be opened;
• and
• each of the plurality of first galvanometer systems is arranged on the first driving unit at intervals along a first direction, and the first driving unit is configured to drive the first laser transmitter and each of the plurality of first galvanometer systems to move along a second direction.
