Robot synchronization sealer discharge system

A robot synchronization sealer discharge system interlocked with a robot for sealer work of a vehicle factory, comprising:

• a sealer gun mounted on a robot and moving along an application path of a vehicle body to discharge a sealer;
• a communication unit configured to receive a Tool Center Point (TCP) speed of the sealer gun moving according to an operation of the robot;
• a synchronization controller configured to assign unique identification information (ID) and a received TCP time to the TCP speed and generate a discharge instruction message recording a sealer discharge amount according to the TCP speed;
• and a sealer controller configured to adjust a discharge of the sealer gun according to the sealer discharge amount of the discharge instruction message and feedback a sealer time according to discharge completion to the synchronization controller, wherein the synchronization controller is configured to derive an offset time as a deviation of the sealer time for the TCP time of a same ID from the feedback data through pre-sealer work and advance a sealer gun operation time at a next sealer work by the offset time to adjust the discharge of the sealer gun at a synchronized time.
