Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, it will be understood by those skilled in the art that in each embodiment of the present invention, propose many ins and outs in order to make reader be more fully understood that the application.But, even without these ins and outs with based on the many variations of following embodiment and amendment, it is also possible to realize the application each claim technical scheme required for protection.
First embodiment of the present invention relates to the control method of a kind of uviol lamp output, is applied to inkjet printing device.Inkjet printing device comprises printer body, intervalometer, controller, UV-detector and at least one uviol lamp；Controller is electrically connected at printer body, intervalometer, UV-detector and uviol lamp.Idiographic flow is as it is shown in figure 1, the control method of uviol lamp output that present embodiment provides comprises step S1 to step S7.
Step S1: controller judges whether to receive detection enabling signal.If so, step S2 is then entered；If it is not, then repeat this step.
Specifically, in intervalometer internal preset one the detection cycle, intervalometer produces detection enabling signal according to the timing of its internal clocking with this detection cycle timing, and this detection cycle can set according to actual needs, for instance is a week or fortnight.Wherein, this detection enabling signal is such as an interrupt signal of this controller, and controller can immediately judge whether to receive to detection enabling signal.
Step S2: controller controls printer body and moves to detection position corresponding to uviol lamp, and in detection position, uviol lamp is positioned at the detection range of UV-detector.
Specifically, UV-detector has certain detection range, and only when uviol lamp is positioned at the detection range of UV-detector, UV-detector could detect ultraviolet light.In present embodiment, UV-detector is fixed on work platforms, and printer body is movably arranged on work platforms, and uviol lamp is fixed on the side of printer body and moves relative to work platforms to follow printer body.Owing to UV-detector is fixed on work platforms, therefore, after controller receives detection enabling signal, first have to control printer body and move to detection position corresponding to uviol lamp.That is, in this detection position, this uviol lamp is positioned at the detection range of UV-detector.
Step S3: controller controls uviol lamp and switches to multiple operation range.
Wherein, uviol lamp has multiple adjustable operation range, corresponds respectively to multiple different output.In present embodiment, uviol lamp has 63 operation range, and the 1st to the 63rd grade of corresponding output increases successively；But the setting of uviol lamp operation range is not intended to be limited in any by present embodiment.
Controller controls uviol lamp and switches to the 63rd grade successively from the 1st grade of beginning.Specifically, different operation range is corresponding to different driving voltages, and the operation range of uviol lamp is more high, and the output of uviol lamp is more big, then the driving voltage needed is also more big.Controller controls uviol lamp by the size of the driving voltage of control input uviol lamp and switches to different operation range.
It is also preferred that the left controller controls uviol lamp stops one section of Preset Time in each operation range, thus being conducive to UV-detector to receive the ultraviolet light that uviol lamp is launched under this operation range.
Step S4: UV-detector receives the ultraviolet detection signal that the ultraviolet light launched under each operation range of uviol lamp is corresponding to produce this operation range, and this ultraviolet detection signal is sent to controller.
That is, when uviol lamp switches to each operation range, UV-detector receives the ultraviolet light of uviol lamp transmitting and converts thereof into ultraviolet detection signal, and ultraviolet detection signal corresponding for each operation range is respectively sent to controller by UV-detector.Wherein, this ultraviolet detection signal is such as voltage signal.
Step S5: controller sets the target operation gear of uviol lamp according to the predetermined power of the multiple ultraviolet detection signals received with this controller internal reservoir.Step S5 comprises sub-step S51 to sub-step S55.
Sub-step S51: multiple ultraviolet detection signals are converted into multiple output by controller respectively.
Specifically, controller internal reservoir has a power conversion formula, multiple ultraviolet detection signals are converted to multiple outputs of correspondence respectively by controller according to this power conversion formula, and wherein, multiple outputs represent this uviol lamp output under multiple operation range respectively.
As shown in Fig. 2 a, 2b, controller produces to comprise shown in output power curve figure, figure the situation of two uviol lamps for inkjet printing device according to the corresponding relation of multiple operation range with multiple outputs, and two curves correspond respectively to two uviol lamps；But the quantity of uviol lamp is not intended to be limited in any by present embodiment.In actual, owing to the different operation range of uviol lamp is to be determined by the different driving voltage inputted, therefore this output power curve figure is essentially driving voltage-output power curve figure, and namely the output of uviol lamp increases along with the increase of driving voltage；Again owing to multiple operation range correspond respectively to multiple driving voltage, and driving voltage is more big, and operation range is more high, therefore, also can clearly drawing from figure, the output of uviol lamp increases along with the increase of operation range, in the most high tap position MAX of uviol lamp, output has maximum.Further, controller can update this output power curve figure according to the current multiple outputs detected after receiving detection enabling signal every time.But, this is not intended to be limited in any by present embodiment, and controller can store an operation range-output synopsis in portion in the inner, to record multiple outputs of multiple operation range and correspondence thereof.
Sub-step S52: controller judges that whether output that the most high tap position of uviol lamp is corresponding is more than or equal to predetermined power, if so, then enters sub-step S53；If it is not, then enter step S6.
Specifically, controller internal reservoir has a predetermined power, and this predetermined power represents: can reach the output of uviol lamp during best ink solidification effect.Owing to the output of uviol lamp increases along with the increase of operation range, therefore have only to compare the magnitude relationship of output corresponding to most high tap position and predetermined power.
In present embodiment, this output preset is A, and controller judges the size of output that uviol lamp is corresponding when the 63rd grade (most high tap position MAX) and this predetermined power A.When output corresponding to most high tap position is more than or equal to predetermined power (as shown in Figure 2 a), represents that this uviol lamp can normally use, namely multiple operation range of this uviol lamp have at least an operation range to disclosure satisfy that the solidifying requirements of ink；When output corresponding to most high tap position is less than predetermined power (as shown in Figure 2 b), represent that this uviol lamp cannot normally use, namely the peak power output of this uviol lamp cannot meet the requirement of cured printing ink, and namely the life-span of uviol lamp has arrived or uviol lamp breaks down.
Sub-step S53: controller calculates the relative difference of multiple output and predetermined power respectively.
Wherein, relative difference refers to the absolute value of output and the difference of predetermined power.
Sub-step S54: controller obtains the output corresponding to relative difference minimum in multiple relative differences.
Wherein, relative difference is more little, represents that uviol lamp output under the operation range that this relative difference is corresponding is closer to predetermined power, when relative difference is zero, then it represents that the output under this operation range is exactly equal to this predetermined power.Owing to predetermined power is not necessarily exactly equal to the output corresponding to some operation range.Therefore, when the minimum relative difference that controller obtains is not zero, represent in multiple outputs that multiple gears are corresponding, output corresponding to this minimum relative difference is closest with this predetermined power, the ultraviolet light that uviol lamp produces under the operation range that this output is corresponding can produce relatively preferably solidification effect, and namely uviol lamp output under the operation range (target operation gear) that this output is corresponding corresponds to predetermined power.
Sub-step S55: operation range corresponding for output is set as the target operation gear of uviol lamp by controller.
Operation range corresponding for this output is labeled as this uviol lamp in the target operation gear of current generation by controller.Thus, before again detecting, controller controls uviol lamp and works in this target operation gear next time.Due to the difference of self manufacturing process shown in Fig. 2 a, the output power curve of two uviol lamps is also different, and therefore the target operation gear of two uviol lamps is also different.
Need illustrate time, predetermined power refers to the output of uviol lamp when can reach best ink solidification effect；And in practical application, good ink solidification effect can be reached when the output of uviol lamp is within the scope of a predetermined power and production requirement can be met.Further, the number of gear of uviol lamp generally divides more, and namely the difference of the output that uviol lamp has multiple output and adjacent gear positions is only small；Therefore, even if the minimum relative difference in sub-step S54 is not zero, namely the output of uviol lamp does not complete to be equal to predetermined power, but the output corresponding to the target operation gear drawn according to present embodiment also is able to meet actual production demand.
Step S6: controller produces caution signals.Namely remind the life-span of operator's uviol lamp to arrive or uviol lamp breaks down, it is necessary to change.
Step S7: controller judges whether also another uviol lamp.If so, step S2 is then returned；If it is not, then terminate this detection.
When inkjet printing device comprises multiple uviol lamp, controller internal reservoir has the mark of each uviol lamp and the detection position that each uviol lamp is corresponding, so that individual each uviol lamp to be detected successively.After each uviol lamp is all detected by controller, terminate this detection.Thus, controller is to each uviol lamp independent detection independent control, the output making each uviol lamp all can meet solidifying requirements, ensure that the balance of multiple uviol lamp output simultaneously, it is to avoid in same print screen, the solidification effect of ink is inconsistent.
The step of various methods divides above, is intended merely to description clear, it is achieved time can be merged into a step or some step is split, and is decomposed into multiple step, as long as comprising identical logical relation, all in the protection domain of this patent；To adding inessential amendment in algorithm or in flow process or introducing inessential design, but do not change the core design of its algorithm and flow process all in the protection domain of this patent.

In present embodiment, intervalometer 11 produces detection enabling signal for timing.Controller 12 starts two uviol lamps 14 are detected respectively after receiving detection enabling signal.The printer body 10 that controls controller 12 moves to detection position corresponding to first uviol lamp, and wherein, when this detection position, first uviol lamp 14 is positioned at the detection range of this UV-detector 13.Controller 12 controls this uviol lamp 14 and switches to multiple operation range；UV-detector 13 receives the ultraviolet detection signal that ultraviolet light that this uviol lamp 14 launches under each operation range is corresponding to produce this operation range respectively, and this ultraviolet detection signal is sent to controller 12；Controller 12 sets the target operation gear of this uviol lamp 14 according to the predetermined power of the multiple ultraviolet detection signals received Yu this controller 12 internal reservoir.Thus, controller realizes the control to first uviol lamp output.In like manner, controller realizes the control to second uviol lamp output.
