Abstract

This utility model relates to the field of cutting machine technology, specifically a vision-based cutting machine. It includes a frame with a horizontal worktable at the top. A displacement mechanism is located above the worktable on the frame, and a cutting mechanism is mounted on the displacement mechanism. The cutting mechanism has a pressure rod capable of independent longitudinal sliding, with a cutter at the bottom of the pressure rod. An extension frame is located on one side of the pressure rod, and a vision positioning mechanism is mounted on the extension frame. The displacement mechanism controls the cutting mechanism to move forward and backward, left and right within a threshold area. A hydraulic mechanism is also provided on the frame, including a lifting frame. When the lifting frame descends, it drives the pressure rod and cutter downwards, performing a punching action on the fabric at the threshold position determined by the vision positioning mechanism on the worktable. This utility model helps solve the problems of some current cutting machines where the cutter and lifting frame have a fixed synchronous lifting structure, resulting in high energy consumption and misalignment between the printed pattern and the finished product outline after punching due to the fixed position of the cutter.
