Automatic (CCD) Counterpoint High Precision Screen Printing Press

What maintenance and care issues should be paid attention to when using an automatic (CCD) dot-to-dot high-precision screen printing machine?

When using an automatic (CCD) dot-to-dot high-precision screen printing machine, the following maintenance and care issues need to be paid attention to:

Regular cleaning and inspection:
Printing plates and screens: Clean the printing plates and screens regularly to avoid ink residue and dirt affecting the printing quality.
CCD system: Clean the CCD camera lens regularly to ensure the accuracy of image recognition.

Check and calibrate the alignment system: Calibrate the alignment system regularly to ensure high-precision dot-to-dot. As the equipment is used for a longer time, the alignment accuracy may need to be adjusted.

Lubricate and check moving parts: Regularly lubricate and check the moving parts of the machine (such as guides, bearings, and transmission systems) to reduce wear and maintain smooth operation.

Check the air pressure and hydraulic system: Ensure that the air pressure and hydraulic system are working properly, and regularly check the status of the cylinder, pipeline, and hydraulic oil.

Regularly check the electrical system: Check the status of cables, connectors, and electrical components to ensure that there is no wear or looseness. Regularly test and maintain the electrical system.

Replace consumables and spare parts:
Replace worn consumables and spare parts such as screens, scrapers and ink pipes according to usage.

Software update and backup:
Regularly check and update the machine's control software to ensure system stability and normal functioning. At the same time, back up important settings and data.

Monitor printing parameters:
Monitor and adjust printing parameters such as ink viscosity, pressure and speed to ensure stable printing quality.

Record and analyze faults:
Record the operation and fault conditions of the equipment, analyze the causes of the faults, and perform targeted maintenance and adjustments to improve the reliability and service life of the equipment.

How to ensure the alignment and repeatability of the image in an automatic (CCD) dot-to-dot high-precision screen printer?

In an automatic (CCD) dot-to-dot high-precision screen printer, it is crucial to ensure the alignment and repeatability of the image. Here are some effective methods and steps:

Use a high-precision CCD system:
Ensure that the resolution and contrast of the CCD system are high enough to accurately identify and align the image. Calibrate the CCD system regularly to maintain its accuracy.

Calibrate the alignment system regularly:
Calibrate the alignment system regularly to ensure the alignment accuracy of the printing template and the substrate. Calibration marks or templates can be used for precise adjustments during calibration.

Stable machine foundation and environment:
Ensure that the machine is installed on a stable foundation to avoid vibration and displacement. Control the temperature and humidity in the environment to reduce image offset caused by environmental changes.

Accurate screen tensioning and fixing:
Ensure that the screen is evenly and firmly tensioned. Unevenly tensioned or loose screens may cause inaccurate alignment of the printed image.

Use high-quality screens and scrapers:
Choose high-quality screens and scrapers to ensure stability and consistency during printing. Regularly check and replace worn parts.

Optimize settings of the automatic alignment system:
Adjust the settings of the automatic alignment system as needed and optimize its alignment algorithm to improve the accuracy of image alignment.

Perform image alignment tests:
Perform image alignment tests regularly to check the printing results of different batches and cycles to ensure repeatability and consistency.

Maintain the mechanical parts of the machine:
Regularly check and maintain the mechanical parts of the machine, such as guides, bearings and servo motors, to ensure their normal operation and avoid the influence of mechanical errors on alignment.
