[0029] Specifically, in this embodiment, the base 1 is an aluminum alloy base, and a material carrier 4, a correction component 2 and a driving component 3 are sequentially installed on the upper surface of the base 1 along the length direction of the base 1. The material carrier 4, the correction component 2 and the driving component 3 are all set at a distance. The fine-tuning driving component 51 is installed on the material carrier 4 and drives the movable rod 52 to move back and forth in the direction of the correction component 4. First, the driving component 3 drives the correction component 2 to move so that the correction component 2 is close to the material carrier 4 and is set at a distance from the material carrier 4 to complete the initial coarse adjustment requirements. Then, the ejector base 10 equipped with a plurality of ejectors 101 is 0 is fixed on the carrier 4, a plurality of ejector pins 101 are arranged toward the correction component 2, and then the fine-tuning driving member 51 drives the movable rod 52 to move, so that the distance between the end of the movable rod 52 and the correction component 2 is smaller than the distance between the needle tip of the ejector pin 101 and the correction component 2, and then the fine-tuning driving member 51 drives the movable rod 52 to move in the opposite direction away from the correction component 2, and then the driving member 3 drives the correction component 2 to move until it contacts the needle tips of some ejector pins 101, and the above actions are repeated until the needle tips of all ejector pins 101 touch the surface of the correction component 2, and the correction process is completed.
