Abstract

This utility model relates to the technical field of lead frame loading and unloading equipment, and more particularly to a material transfer mechanism for high-density integrated circuit lead frames. It includes a support platform, on which a conveying module is mounted. The support platform has a feeding port located beside the initial end of the conveying module. A conveying assembly is provided beside the conveying module to transport lead frames placed at the feeding port one by one to the conveying module. The conveying assembly includes a support base and a movable frame laterally mounted on the support base. The movable frame is equipped with a lifting frame. The bottom of the lifting frame is equipped with a front movable rod and a rear movable rod that can move laterally towards or away from each other. Each of the front and rear movable rods is equipped with a mounting plate, and each mounting plate is equipped with multiple flexible grippers for clamping the lead frames. By controlling the front and rear movable rods to move closer or further apart, the distance between the flexible grippers on both sides can be adjusted to accommodate lead frames of different sizes.
