    There are two types of large-sized flat screen printing machines, pneumatic screen printing machines and electric screen printing machines. Due to the instability of pneumatic screen printing machines, the market share of electric screen printing machines is constantly expanding. The so-called electric screen printing machine means that the up and down movement of the screen and the left and right movements of the scraper are controlled by the motor instead of the cylinder. Relatively speaking, the electric control screen printing machine is powerful and can maintain a relatively stable pressure throughout the printing process. . In order to further improve the accuracy, these two actions are increasingly controlled by servo motors. Servo motor control is more convenient to operate and adjust, and has higher precision, but the price is also more expensive. 

Single-chip microcomputer high-precision flat screen printer:

Suction table

• Steady adsorption of workpieces: The suction table can firmly adsorb the flat workpiece to be screen-printed on the table by generating negative pressure. Whether it is light and thin paper, plastic sheets, or slightly hard metal sheets and other workpieces of different materials, they can be stably fixed, effectively avoiding the displacement of the workpiece during the screen printing process, laying a solid foundation for precise printing and ensuring the position accuracy of the printed pattern.

• Keep the workpiece flat: For some workpieces that may have slight warping or unevenness, the adsorption effect of the suction table can keep it as flat as possible during printing. In this way, the screen plate can better fit the surface of the workpiece, which is conducive to the uniform transfer of ink through the screen to the workpiece, ensuring the integrity and clarity of the printed pattern, and improving the quality of screen printing.

Single-chip microcomputer control

• Accurate parameter adjustment: The single-chip microcomputer control system can accurately set various key parameters of the screen printer. For example, it can accurately control the speed of screen printing, determine the appropriate scraper movement speed according to different workpiece materials, pattern complexity and other factors, and ensure that the ink is transferred evenly and smoothly; it can also accurately control parameters such as scraper pressure and the distance between the screen and the workpiece. For example, when printing fine circuit board patterns or high-resolution images, the precise control of the single-chip microcomputer ensures that every detail can be clearly presented to achieve high-precision printing effects.

• Multiple printing mode switching: The operation interface provides a variety of preset printing modes for selection. For example, for simple monochrome text printing, the high-efficiency mode can be selected to speed up printing speed and improve production efficiency; for complex patterns that require multi-color overprinting and high color transition requirements, switch to high-precision mode, which can finely control the printing order, superposition effect and dwell time of each color, ensure that the pattern color is accurate and rich in layers, meet diverse printing needs, and make the screen printer more flexible.

Screen upper and lower linear guide control

• Precise positioning and motion control: The screen is controlled by upper and lower linear guides, and its motion trajectory is accurate and stable, which can ensure that the screen can be accurately lifted and lowered in the vertical direction. During the screen printing process, the screen can be accurately lowered to fit the surface of the workpiece according to the set height, and can rise smoothly back to the initial position after the ink transfer is completed, effectively avoiding problems such as uneven ink distribution and blurred patterns caused by unstable screen movement, greatly improving the printing accuracy.

• Guaranteeing repeatability: For situations where screen printing needs to be repeated multiple times, such as multi-color overprinting or batch production of workpieces with the same pattern, the screen controlled by the linear guide can ensure that the position and angle of each descent are highly consistent, so that each printed pattern can be accurately superimposed or repeated, achieving high-quality stable printing effects, and meeting production tasks with demanding printing accuracy, such as high-end electronic product panel printing, exquisite album inner page printing, etc.

High-precision embodiment and application advantages

• Key to high-precision output: The vacuum workbench's stable adsorption and flattening of the workpiece, the precise parameter adjustment of the single-chip control, and the precise movement of the upper and lower linear guides of the screen, these functions cooperate and work together to ensure the high-precision output of the screen printer from multiple links. Whether printing tiny text, fine lines, or complex color patterns, it can achieve clear, accurate, and beautiful effects, meeting the demand for products with extremely high requirements for printing quality.

• Expanding application areas: With its high-precision screen printing capabilities, this screen printer can be widely used in many industries such as electronics, printing and publishing, advertising, and handicrafts. In the electronics industry, it can print fine circuits and logos for circuit boards; in the printing and publishing field, it can be used to produce high-quality picture albums and art reproductions; in the advertising industry, it can produce exquisite posters and leaflets; in the handicraft industry, it can create exquisite decorative ornaments, etc., providing reliable and high-quality printing solutions for the appearance decoration and content presentation of various products, improving the added value and market competitiveness of products, and promoting the continuous progress of related industries in product quality.

In summary, this high-precision flat screen printer with suction workbench, single-chip microcomputer control, and upper and lower linear guide rail control of the screen has significant advantages in the field of flat screen printing, and can provide high-quality and accurate printing services for various industries to meet diverse market needs.
