Technical Problem

然而，这种方法的缺点在于，由于环境温度、油墨粘度等因素的变化，可能导致油墨的添加量不稳定，从而影响印刷质量；此外，这种方法所使用的油墨泵送系统还需要定期维护和调整，油墨品种较多时还需要更换管路，更换动作耗时较长增加了设备的运行成本

Benefits of technology

[0058] By installing an automatic ink-adding component on the print head of a circuit board screen printing machine, printing ink can be automatically added to the screen printing plate of the circuit board under the screen printing plate on the printing host during screen printing. The current ink level in the automatic ink-adding component can be monitored in real time, which can accurately control the amount of ink added, improve printing quality and efficiency, facilitate maintenance and changeover, and reduce equipment operating costs. The current ink level in the automatic ink-adding component can be obtained in real time during the screen printing process of the circuit board.

Abstract

The application relates to a solder resist screen printing control method, a system and a circuit board screen printing machine. The method is applied to a circuit board screen printing machine; the circuit board screen printing machine comprises a printing main machine with a printing area, a screen printing plate arranged at the printing area, a printing head arranged on the printing main machine and located above the screen printing plate, and a screen printing automatic ink adding assembly arranged on the printing head; the method comprises the following steps: controlling the screen printing automatic ink adding assembly to automatically add printing ink to the screen printing plate, and simultaneously controlling the printing head to perform screen printing on a circuit board under the screen printing plate; in the process of performing screen printing on the circuit board, the current ink amount in the screen printing automatic ink adding assembly is acquired in real time; when it is detected that the current ink amount in the screen printing automatic ink adding assembly is lower than a preset ink amount, a prompt ink adding signal is sent. The application can accurately control the adding amount of the ink, improve the printing quality and efficiency, is convenient to maintain and change, and reduces the operation cost of the equipment.
