This utility model discloses an automatic rubber tire tread bonding device, including a base and a rolling mechanism, a robotic arm, and a bonding machine mounted on the base. The rolling mechanism includes a support plate, a drive motor, and an inner support member. The bottom of the support plate is fixedly connected to the base, and the drive motor is mounted on the support plate to provide stable and continuous rotational power to the inner support member.
