Abstract

The invention provides a system and method for negative-pressure ink supply of rigid printed circuit board jet printing equipment. The system comprises a vacuum pump, a vacuum generator, an ink box, a spray head, an ink bottle and an ink supply pump, wherein the vacuum pump is connected with the vacuum generator; the vacuum generator is connected with the ink box; the ink box is connected with the spray head; the spray head is positioned below the ink box; the ink supply pump is connected with the ink box; and the ink bottle is connected with the ink supply pump. In the method, negative-pressure interaction is generated in the ink box through the pressure generated by ink level in the ink box and the vacuum generator, and then a working negative pressure is formed at the spray head so as to realize stable ink supply. Compared with a negative-pressure ink supply system of conventional rigid printed circuit board jet printing equipment, the technical scheme provided by the invention has the characteristics of short ink path, high ink supply stability and the like.

Description

technical field [0001] The invention relates to rigid printed circuit board jet printing equipment, in particular to a negative pressure ink supply system and method for rigid printed circuit board jet printing equipment. Background technique [0002] Rigid printed circuit board printing equipment belongs to an inkjet system. In the inkjet system, the ink supply system is a key technology. The size and stability of the negative pressure it provides will directly affect the quality of the inkjet system. [0003] The existing rigid printed circuit board printing ink supply method is the liquid level difference siphon ink supply method, the height of the ink cartridge is lower than the height of the nozzle, and the ink negative pressure at the nozzle is maintained by using the liquid level difference between the nozzle and the ink cartridge. [0004] The main problems at present: 1. The ink pressure in the ink supply system is in the state of atmospheric pressure and normal pre...
