Method for replacing capillary

A method for replacing a capillary of a wire bonding apparatus using a capillary replacing unit loaded on a mobile robot, the method comprising:

• receiving a capillary replacement start signal from at least one of a plurality of wire bonding apparatuses;
• autonomously moving the mobile robot that received the replacement start signal to the wire bonding apparatus that transmitted the replacement start signal to load the capillary replacing unit onto the wire bonding apparatus;
• separating, by the capillary replacing unit, the capillary corresponding to the replacement start signal from the wire bonding apparatus;
• and
• installing, by the capillary replacing unit, a new capillary in the wire bonding apparatus,

A capillary replacing apparatus, comprising:

• a capillary replacing unit that replaces a capillary of a wire bonding apparatus, and
• a mobile robot that transfers the capillary replacing unit to the wire bonding apparatus in response to receiving a replacement start signal from the wire bonding apparatus,
• wherein the capillary replacing unit comprises
• a gripper that grips a capillary,
• a cradle with a plurality of holes that hold new capillaries,
• a collection container that receives used capillaries, and
• a transfer unit that moves the gripper to and from the cradle or the collection container.
