Abstract
The invention provides a system and method for stabilizing negative ink-supplying pressure for spray printing of a rigid printed circuit board. The system comprises a vacuum pump, a first buffering bottle, a vacuum generator, a second buffering bottle and a nozzle device, wherein the vacuum pump is connected with a long pipe opening of the first buffering bottle and a short pipe opening of the first buffering bottle is connected with the vacuum generator; the vacuum generator is connected with the short pipe opening of the second buffering bottle and the long pipe opening of the second buffering bottle is connected with the nozzle device. The method comprises the following steps that: pulse air generated by the vacuum pump is stabilized by the first buffering bottle to be conveyed into the vacuum generator; and a pulse negative pressure generated by the vacuum generator is stabilized by the second buffering bottle to realize the stable negative pressure of the nozzle device. According to the technical scheme provided by the invention, the change of the ink-supplying pressure can be effectively reduced through two stages of buffering systems.
Description
Technical field
The present invention relates to rigid printed circuit boards spray printing negative pressure ink supply pressure stability system and method.
Background technology
Rigid printed circuit boards spray printing equipment belongs to a kind of ink-jet apparatus, and in ink-jet system, ink feeding system is a key technology, and the size of the negative pressure that it provides and stability will directly influence the quality of system's ink-jet.
Existing rigid printed circuit boards spray printing ink supply mode is a liquid level difference siphon ink supply mode, and the print cartridge height is lower than sprinkler height, utilizes the ink negative pressure hold mode at the liquid level difference formation shower nozzle place between shower nozzle and the print cartridge.Adjust the negative pressure value of ink feeding system through change liquid level difference between the two.
Present subject matter: 1. black road length causes China ink pipe internal resistance bigger, and ink feeding system China ink road pressure can't keep stablizing and is prone to gas in the 2. ink supply pipes and in ink, separates out, and causes pore to be deposited in the pipeline, influences the stability of liquid level difference negative pressure.3. ink feeding system does not have the pressure buffer device.
Summary of the invention
The invention provides a kind of rigid printed circuit boards spray printing negative pressure ink supply pressure stability system and method, can overcome the problem of pressure stability in the conventional rigid printed circuit board spray printing negative pressure ink supply system.
The present invention realizes through following technical scheme.
