Description

Technical Field

[0001] The present invention relates to the field of circuit boards, and particularly to a circuit board printing device. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, printed circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin printed circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards can be called printed wiring boards or printed circuit boards. The birth and development of flexible-rigid printed circuit boards - FPCs and PCBs have given rise to this new product. Therefore, a flexible-rigid printed circuit board is a circuit board formed by combining a flexible printed circuit board and a rigid printed circuit board through processes such as lamination and combining them together according to relevant process requirements, having the characteristics of both FPCs and PCBs.

[0003] All electronic devices are inseparable from circuit boards. From small electronic watches, calculators, and general-purpose computers to large computers, communication electronic devices, and military weapon systems, as long as there are electronic components such as integrated circuits, electrical interconnections between them all use circuit boards. Circuit board printing (PCB printing) usually refers to the conductive pattern formed by making printed circuits, printed components, or a combination of both on an insulating material according to a predetermined design as a printed circuit, and the conductive pattern providing electrical connections between components on an insulating substrate is called a printed wiring. In this way, the finished board of a printed circuit or a printed wiring is called a printed wiring board, also known as a printed board or a printed circuit board.

[0004] A circuit board printing machine is a device that prints an acid-resistant film layer onto the surface of a copper plate through screen printing during the process of making a circuit board to protect the circuit from corrosion. A circuit board printing machine usually includes a workbench for carrying the workpiece to be processed, i.e., the circuit board, and a squeegee mechanism disposed above the workbench. After covering the workpiece to be processed on the workbench with a printing plate, the squeegee of the squeegee mechanism can scrape the ink across the printing plate under the drive of a driving device and print it on the workpiece to be processed. However, the surface of the printing plate is contaminated by the ink during printing, and the ink is likely to stick to the hands when replacing the printing plate and is not easy to wash off.

[0005] Therefore, it is necessary to provide a circuit board printing device to solve the above technical problems. Summary of the Invention
