How Does CCD Hole Punching Machine Work?
2023-10-20

Working Principle of CCD Hole Punching
-
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.
-
-
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.
-
-
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.
-
-
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.
-
-
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.
