Abstract
The invention provides a method for controlling the spray printing ink filling of a rigid printed circuit board. The method comprises the following steps of: setting the upper limit value and the lower limit value of an ink liquid level; measuring normal ink supply duration; feeding the normal ink supply duration back to a real-time liquid level in a control system through a floater; controlling an ink supply pump to be started and stopped; and giving an alarm by the control system and stopping ink supply work when the ink supply time is abnormal. By using the technical scheme of the invention, error correction and alarm functions of a liquid level control system are realized through simple procedure control, and the safety of the system is improved on the basis that the cost is not increased.
Description
Technical field
The present invention relates to rigid printed circuit boards ink-jet ink filling control method.
Background technology
The ink supply of head cartridge is to accomplish through automatic control in the rigid printed circuit boards spray printing equipment, when the head cartridge liquid level is lower than setting value, need ink in the one-level print cartridge be pumped into through the ink supply pump, and when being higher than setting value then, the ink supply pump stops ink supply.
At present the filling control method be install in the head cartridge float and with ink supply pump composition closed circuit; By the liquid level position in the float inductive head print cartridge; Whether the closure of control circuit is controlled the ink supply pump with this and is worked, and finally reaches the purpose of ink can in the control head print cartridge.
The operation principle of float level meter is that float receives buoyancy to float over dielectric surface, to graduated steel band, reads level value through change-speed gearing, and after dynamic balance had been broken in liquid level rising or decline, float was also followed rise and fall, drove the steel band operation.Because mechanical part is many, is easy to take place the stuck motionless situation of steel band, causes the output error in data, control ink supply pump is malfunctioning.
Summary of the invention
The present invention provides a kind of rigid printed circuit boards ink-jet ink filling control method, has realized the error correction warning function of tank level control system.
Rigid printed circuit boards ink-jet ink filling control method of the present invention comprises:
Set liquid level higher limit and lower limit in the head cartridge;
Measure the interior ink level of head cartridge from the lower limit to the higher limit, the required ink supply duration of ink supply pump T1;
Setting work duration upper limit T2, and T2 is 1.5～2 times of T1;
Float feeds back to the control system with real-time level;
When real-time level was higher than the liquid level higher limit of setting, the control system output signal made the ink supply pump quit work;
When real-time level was lower than the liquid level lower limit of setting, the control system output signal made the ink supply pump start working;
In the continuous ink feeding process, the control system picks up counting from this ink supply pump startup, and arrival setting duration upper limit T2 does not also reach on the liquid level and prescribes a time limit, and the control system starts warning device, and the output signal makes the ink supply pump quit work.
Rigid printed circuit boards ink-jet ink filling control method provided by the invention; On the basis that does not change original device; The error correction warning function of tank level control system, the security that on the basis that does not increase cost, has improved system have been realized through simple programme-control.
The specific embodiment
Rigid printed circuit boards ink-jet ink filling control method of the present invention may further comprise the steps:
Set liquid level higher limit 65mm and lower limit 5mm in the head cartridge;
Measure in the head cartridge ink level from the lower limit to the higher limit, the required ink supply duration of ink supply pump, repeated measurement repeatedly, averaging is 180s;
Setting work duration upper limit 270s is 1.5 times of ink supply duration mean value 180s;
Float feeds back to the control system with real-time level;
When real-time level was higher than 65mm, the control system output signal made the ink supply pump quit work;
When real-time level was lower than 5mm, the control system output signal made the ink supply pump start working;
In the continuous ink feeding process, the control system picks up counting from this ink supply pump startup, and liquid level does not also reach 65mm behind the 270s, and the control system starts warning device, and the output signal makes the ink supply pump quit work.
