Working Principle of CCD Hole Punching

  1. CCD Camera Captures the Image

    • The machine is equipped with a CCD vision system (high-resolution camera + lens).

    • When a sheet or roll material is placed on the worktable, the CCD camera scans the printed marks, guide holes, or target patterns on the surface.

  2. Image Recognition & Positioning

    • The captured image is sent to the industrial computer.

    • Special image-processing software analyzes the marks and calculates the exact punching coordinates.

    • This eliminates human error and ensures alignment, even if the material shifts slightly.

  3. Automatic Alignment

    • The system adjusts the position of the material using servo motors, guide rails, and precise transmission components.

    • It automatically aligns the punching die with the target hole position.

  4. High-Precision Punching

    • Once aligned, the punching head (die + punch pin) is activated, usually by a pneumatic cylinder.

    • The punch goes through the material at the exact position determined by the CCD system.

    • Accuracy can reach ±0.01–0.02 mm depending on the model.

  5. Cycle Repeats Automatically

    • The process repeats for each hole.

    • For semi-automatic models, the operator loads/unloads the material.

    • For fully automatic models, the machine handles feeding, positioning, punching, and collecting materials in one cycle.

Key Advantages of CCD Hole Punching

  • High precision: Accurate to within microns.

  • Fast speed: Typically 0.3–0.5 seconds per hole.

  • No dragging or misalignment: Material shifts are corrected by CCD recognition.

  • Versatility: Works on PET, PC, PVC, metals, nameplates, flexible circuits, and films.

  • Automation: Reduces manpower, improves consistency.
