Lamp of the present utility model source 14 is a red LED, and it is a plurality of, is distributed in the periphery of photoelectric sensor 12, and simultaneously, light barrier 13 also is a plurality of, and correspondence is distributed in the periphery of photoelectric sensor 12, and the detection light that intercepts the output of lamp source fully directly transfers to photoelectric sensor; Photoelectric sensor 12 is linear digital light-sensitive device group (LINEAR OPTICAL SENSOR ARRAY).
The utility model print quality detection module per second can detect omnidistance detection of printing under length 96.25mm or 3.789 inches, the general print speed.The communication modes of PORT COM is three-way standard I O mouth: SCLK, SDIN, SDOUT.
The operation principle of the utility model print quality detection module is as follows:
Red LED irradiation printing paper, the color at the illuminated place of printing paper is dark more, after then the light of its reflection is received by the light-sensitive device of photoelectric sensor, it is more little to carry out the value that opto-electronic conversion obtains, otherwise the color at the illuminated place of printing paper is shallow more, after then light-sensitive device receives reflection ray, it is big more to carry out the value that opto-electronic conversion obtains, like this, and the value that the color on the printing paper obtains corresponding to opto-electronic conversion.Photoelectric sensor can not directly receive the irradiation of red LED, can increase excessive interference like this, so adopted light barrier in the both sides of photoelectric sensor, stops red LED direct irradiation photoelectric sensor.
Quality detection module is printed in the design one of the utility model initiative, utilize the lamp source emission of this print quality detection module to detect light, this detection light receives and changes into detection signal by photoelectric sensor after the printing paper reflection, judge print quality according to detection signal, can in time find the underproof printed tickets of print quality, and, carry out necessary processing, thereby put forward the whole print quality of printer in time by signal notifying operation personnel or host computers such as sound, light, electricity.
As shown in Figures 1 to 4, a kind of printer 200, it comprises print quality detection module 100, this print quality detection module 100 is used for the print quality of monitoring printer, to guarantee the printing effect of printer.It comprises gripper shoe 11, photoelectric sensor 12, light barrier 13, lamp source 14 and PORT COM (not shown go out); Gripper shoe 11 is installation bases of other each parts, plays a part to support, and photoelectric sensor 12, light barrier 13 and lamp source 14 are fixedly arranged on gripper shoe.Photoelectric sensor 12 is used for receiving detection light, and transforms into detection signal through photoelectricity.Lamp source 14 is used for emission and detects light, thereby produces reflection on the surface of printing paper.PORT COM is used for detection signal is sent to the main control processor of printer., the utility model is provided with light barrier 13 for the interference to photoelectric sensor 12 of the detection light of eliminating lamp source 14 emission between photoelectric sensor 12 and lamp source 14, stop that the detection light in lamp source 14 directly transfers to photoelectric sensor 12.
Lamp of the present utility model source 14 is a red LED, and it is a plurality of, is distributed in the periphery of photoelectric sensor 12, and simultaneously, light barrier 13 also is a plurality of, and correspondence is distributed in the periphery of photoelectric sensor 12, and the detection light that intercepts the output of lamp source fully directly transfers to photoelectric sensor; Photoelectric sensor 12 is linear digital light-sensitive device group (LINEAR OPTICAL SENSOR ARRAY).
The utility model print quality detection module per second can detect omnidistance detection of printing under length 96.25mm or 3.789 inches, the general print speed.The communication modes of PORT COM is three-way standard I O mouth: SCLK, SDIN, SDOUT.
The operation principle of this print quality detection module is as follows:
Red LED irradiation printing paper, the color at the illuminated place of printing paper is dark more, after then the light of its reflection is received by the light-sensitive device of photoelectric sensor, it is more little to carry out the value that opto-electronic conversion obtains, otherwise the color at the illuminated place of printing paper is shallow more, after then light-sensitive device receives reflection ray, it is big more to carry out the value that opto-electronic conversion obtains, like this, and the value that the color on the printing paper obtains corresponding to opto-electronic conversion.Photoelectric sensor can not directly receive the irradiation of red LED, can increase excessive interference like this, so adopted light barrier in the both sides of photoelectric sensor, stops red LED direct irradiation photoelectric sensor.
Quality detection module is printed in the design one of the utility model initiative, utilize the lamp source emission of this print quality detection module to detect light, this detection light receives and changes into detection signal by photoelectric sensor after the printing paper reflection, judge print quality according to detection signal, can in time find the underproof printing paper of print quality, and in time solve the underproof problem of print quality, thereby put forward the whole print quality of printer.
The utility model is embedded print quality detection module 100 in printer 200, thereby detects print quality in real time, and this print quality is fed back to main control processor, with the underproof problem of solution print quality, thus the print quality of assurance printer.
Operation principle:
The utility model detects in real time to print quality; Detection signal in printing, occurs and be lower than when setting thresholding, report to the police to main control processor in real time, help main control processor in time to understand the print quality state, and handle accordingly, to guarantee print quality.
Current printer is not printed the monitoring function module, and the nothing that air exercise India and China occur is printed, the phenomenon of print quality difference can't be made feedback, and then can't in time handle accordingly to improve print quality.
The difference of printing paper shade to reflection of light degree difference, thereby makes photoelectric sensor obtain judging according to the size of this value whether this point is printed with the corresponding value of shade.The detectable width of photoelectric sensor is 8.636mm, and each test point area is 85m (H) * 77m (W), and per second can detect 1250 row, and per second can detect length 96.25mm or 3.789 inches.
Adopted the method for statistics to determine whether printing paper has printing, the value in delegation has the data above 20% to be lower than threshold value, thinks that then this row has printing; Have the line number of printing to surpass 10%, then being judged as printing paper has word.
After receiving the order that main control processor begins to detect, print identification module and start working, when make judge conclusion after, report main control processor, and enter holding state.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
