    Product Detail

    CCD Alignment System with UVW Platform Micro-Adjustment for Precise Registration

    • Equipped with a CCD alignment system, the device automatically captures images of any pattern or hole position. The central control system autonomously calculates the deviation, and then the UVW platform, driven by high-precision motors and lead screws, performs micro-adjustments in the X/Y/θ directions to ensure positional error within ±0.02mm.

    • Each machine is equipped with a frame micro-adjustment handle. The alignment time for changing the stencil takes only 5-10 minutes, offering a simple and efficient process that prevents production delays.

    • The printing platform's flatness reaches ±0.08mm, with a one-piece cast aluminum structure, ensuring strong printing uniformity.

    Stable Control Device for Off-Network Speed, No Residual Ink and No Deformation

    • The stencil lifting and squeegee speed are independently controlled by a frequency conversion drive system, allowing for separate speed adjustments based on printing requirements, offering flexible adaptation to different complexities of circuit patterns and character demands.

    • The squeegee and doctor blade use a separate precision pressure control system, allowing for flexible adjustment of the ink pressure and angle.

    • The precision pressure valve controls the instantaneous off-network action, ensuring the printing results are free from residual ink and deformation.

    Fully Automated Printing Mode, Fast and Seamless Operation

    • The stencil frame waits in the center position during the printing interval, shortening the motion travel, and increasing the printing speed to 6-10 boards per minute. It is also equipped with multiple safety protections to ensure operator safety.

    Frequently Asked Questions (FAQ)

    Q:What is the registration accuracy of the CCD alignment system?

    The machine uses a CCD alignment system combined with a UVW micro-adjustment platform driven by high-precision motors and lead screws, ensuring a positional registration error within ±0.02mm.

    Q:How long does it take to align a new stencil frame?

    Thanks to the integrated frame micro-adjustment handle, the alignment time for changing a stencil is highly efficient, taking only 5 to 10 minutes.

    Q:How does the machine prevent residual ink and deformation during printing?

    The system employs a precision pressure valve to control the instantaneous off-network action, paired with independent frequency conversion drives for stencil lifting and squeegee speed, ensuring clean results without residual ink or deformation.

    Q:What is the average printing speed of the fully automated mode?

    The printing speed ranges between 6 to 10 boards per minute (or up to 11 pieces per minute depending on the model and circuit complexity) by keeping the stencil frame centered to shorten motion travel.

    Q:What safety features are included in the CCD PCB screen machine?

    To ensure maximum operator safety, the machine is built with multiple safety protections, including a through-beam light grating and a self-locking air valve system.

    Q:What is the flatness specification of the printing platform?
