There are many types of fully automatic screen printing machines. The common classification methods and specific types are as follows:
1. Classification by the type of printed substrate:
• Paper-type fully automatic screen printing machine: mainly used for printing on paper, such as various book covers, posters, leaflets, etc. This type of screen printing machine has good adaptability to paper transportation, positioning, and ink adhesion.
• Plastic-type fully automatic screen printing machine: suitable for printing on plastic substrates, such as plastic bottles, plastic containers, plastic films, etc. Since the surface properties of plastics are different from other materials such as paper, this type of screen printing machine will have corresponding adjustments and optimizations in ink selection, printing pressure control, etc. to ensure printing quality. For example, it is widely used in cosmetic packaging, food packaging and other fields.
• Ceramic-type fully automatic screen printing machine: specially used for printing on ceramic products, such as ceramic tableware, ceramic decorations, tiles, etc. The surface of ceramic materials is relatively rough, and the requirements for ink adsorption and printing firmness are high, so this type of screen printing machine is usually equipped with special inks and printing processes to meet the needs of ceramic printing.
• Glass automatic screen printer: mainly used for printing on glass substrates, such as glassware, glass doors and windows, glass crafts, etc. The glass surface is smooth, and the printing accuracy and ink adhesion are required to be high. At the same time, the fragility of glass needs to be considered, and the stability and safety of operation must be ensured during the printing process.
• Circuit board automatic screen printer: used for the production of printed circuit boards (PCBs), widely used in the electronics industry. The printed patterns on the circuit boards require high precision and clear lines, so this type of screen printer needs to have high-precision positioning and printing capabilities, and can accurately print ink at the designated position on the circuit board.
• Metal automatic screen printer: suitable for printing on metal substrates, such as metal sheets, metal products, metal packaging, etc. The hardness of the metal surface is high, and the wear resistance of the screen printer's scraper and screen is required to be high. At the same time, special inks and curing methods are required to ensure the firmness of the printed pattern.
• Textile automatic screen printer: mainly used for printing on textiles, such as clothing, fabrics, curtains, etc. Textiles are soft and easy to deform, so this type of screen printing machine needs to have a good fabric conveying and positioning system to ensure the accuracy of printing.
2. Classification by the structure and working mode of the printing machine:
• Flat screen printing machine: It uses a flat screen plate to print on a flat substrate. It is the most common type of fully automatic screen printing machine. Its working principle is that the squeegee presses the printing plate and moves horizontally, and the substrate is changed by the rise and fall of the printing plate. It is suitable for printing various flat materials, such as paper, plastic sheets, metal plates, etc.
• Curved screen printing machine: It uses a flat screen plate to print on a round or curved substrate. The squeegee is usually fixed, the printing plate moves horizontally, and the substrate rotates with the same linear speed of the printing plate. It can be printed on various curved objects, such as cylindrical containers, spherical objects, irregular surfaces, etc.
• Rotary fully automatic screen printing machine: It uses a cylindrical screen plate, and a wedge-shaped squeegee or squeegee roller is installed inside the cylinder. The linear speed of the printing plate rotation and the movement of the substrate is the same. This type of screen printer has a fast printing speed and high efficiency, and is suitable for large-scale continuous printing operations. For example, it is widely used in the printing of materials such as plastic films and paper rolls.
• Elliptical fully automatic screen printer: It has a rotary structure, coaxial platform rotation, variable frequency electric printing, and mechanical fast positioning. It has many workstations and an expandable structural design. It can combine printing and drying workstations according to actual conditions. It is often used for printing clothing pieces and can print paste, water slurry, ink and other slurries.
3. Classification by other special functions or application areas:
• IT window glass fully automatic screen printer: Developed and designed to meet the needs of the IT industry for high-precision, intelligent and automated screen printing equipment, it can automatically transfer and has machine vision positioning and printing functions, and can automatically connect with the previous and next processes.
• Solar crystalline silicon cell fully automatic screen printer: It consists of fully automatic film loading, film storage, automatic film feeding, machine vision automatic positioning, automatic printing, automatic transfer and film output systems, and is mainly used for screen printing of solar crystalline silicon cells.
• PCB process fully automatic screen printer: designed for the circuit board (PCB)'s demand for high-precision, intelligent, and automated screen printing equipment, it has CCD visual recognition automatic alignment, automatic transmission, and printing functions, and can automatically connect with the previous and next processes.
• Optoelectronic Display Technology Fully Automatic Screen Printer: Horizontal design, consisting of three parts: import, print, and export. It uses CCD visual automatic alignment, high precision, and is suitable for high-precision fully automatic screen printing of flat substrates, such as PLC, EL, LED, IMD, glass, PCB circuit boards, etc.
