Description

Printer intelligent control circuit

Technical Field

The invention belongs to the technical field of printing, particularly relates to an intelligent printing technology, and relates to a printer control circuit.

Background

In the known prior art, the printer is simple and has a small number and variety of sensors. The printer has no cognitive ability on the printing medium and the surface, a plurality of steps need manual intervention or adjustment in advance, and the rejection rate of printed products is high.

Printers are known that are positioned according to the side edges of the print medium, positioning strips, positioning holes, and the like. According to the known printing positioning mode, when a printing medium is printed and cut, left-right deviation or inclination occurs, and a printer may not print accurately; when the orientation of the print medium is placed incorrectly (e.g., the top and bottom are placed upside down, the background picture of the print medium is also placed upside down, etc.), the printer cannot print correctly. The printers known today cannot seamlessly continue printing on unfinished print media after a print interruption. Not only can cause the waste of materials, but also takes trouble, wastes time and labor, has high requirements on the skill quality of printing personnel, and increases the labor cost, the time cost and the material cost. There is therefore a need for an effective solution to address the above-mentioned problems.

The invention provides an intelligent control circuit of a printer, which can realize the purpose of replanning a printing scheme according to the printed condition or the printing condition of a printing medium; after abnormal printing is interrupted, seamless continuous printing can be performed on the medium which is not printed; seamless repairing printing can be carried out on the missed printing part; the gap between the printing head and the printing medium can be measured, manual intervention or adjustment is not needed, labor cost, material cost and time cost are saved, and user experience is improved.

The technical scheme of the invention is as follows: an intelligent control circuit for printer is composed of main controller, bus controller, memory module and wired or wireless data link. The main controller comprises a CPU component, a GPU component, an AI component and the like. The storage component comprises hardware, software and the like. The hardware comprises a memory, a memorizer and the like. The software includes an operating system, an application system, program data, and the like.

Furthermore, the invention is characterized in that:

the intelligent control circuit of the printer has higher information data operation processing capacity such as pictures, AI processing capacity and data storage capacity. The device is connected with a computer system (an upper computer) through a wired or wireless data link, is in data communication with a camera and an auxiliary lighting assembly, a displacement sensor assembly, a distance measuring sensor assembly and other sensor assemblies on the printing head through the wired or wireless data link, and is connected with the printing head assembly and other electric modules through a driving circuit.

Further, it is assumed that a camera and auxiliary lighting assembly, a displacement sensor assembly, a distance measuring sensor assembly, other sensor assemblies, and the like are mounted on the print head to move together with the print head. The camera and the auxiliary lighting assembly on the printing head shoot pictures for the printing medium, the displacement sensor acquires displacement data of the printing head on the printing medium, the distance measuring sensor assembly measures gap data of the printing head and the printing medium, the gap data is transmitted to the printer intelligent control circuit in a lump, and the pictures are spliced, identified, measured and positioned by the printer intelligent control circuit. So as to plan the printing scheme before printing, monitor the printing effect during printing and ensure the qualified products by the printing mechanism. Before printing, the intelligent control circuit of the printer shoots pictures of a printing medium through a camera, and observes, identifies, measures and positions the positions, sizes, widths, heights, angles, distances and directions between printed patterns, icons, tables, characters and the like on the printing medium by combining displacement data obtained by a displacement sensor, and plans a printing scheme. During printing, the intelligent printing control circuit shoots pictures of a printing medium through the camera, judges that repairable failed printing is realized through observation and identification, replans the printing scheme again, and repairs and prints in time; and the failed printing which is judged to be unable to be repaired is timely terminated.

Detailed Description

The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims. It should be noted that the embodiments and features of the embodiments may be interchanged, combined, or separated without conflict.

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings.

The invention provides an intelligent control circuit of a printer, which comprises a main controller 104, a bus controller 112, a storage controller 114, a storage component 116, a wired or wireless data link 152 and the like, as shown in figure 1. The main controller 104 includes a CPU component 106, a GPU component 108, an AI component 110, and the like. The storage component 116 includes hardware 118 and software 124, among other components. The hardware 118 includes a memory 120, a storage 122, and the like. Software 124 includes operating system 126, application systems 128, program data 130, and the like.

Printhead assembly 144 can be any known printhead assembly and can be adapted for use with the present invention. Further description of these features is omitted here, and only the inkjet printhead assembly including the nozzle and ink reservoir and the like is described as an example.

Preferably, as shown in fig. 1, 2 and 3, in the present embodiment, the computer system 132 (host computer) transmits the print data, the background picture 302 and the positioning information 304 to the printer intelligent control circuit 102 through the wired or wireless data link 152. The background picture 302 is all or part of a pattern existing before the present printing on the printing medium. The positioning information 304 may be all or part of one of the patterns, icons, tables, texts, colors, etc. in the background picture 302, or may be a partial combination or all combination of the patterns, icons, tables, texts, colors, etc. The location information 304 may be more than one. Each location information 304 is unique in the background picture 302. The positioning information 304 has directionality due to the use of patterns, icons, tables, characters, colors, or the like. The print data includes print content 402 (including patterns, icons, tables, text, colors, etc.) and also includes differences in dot columns 404 in one or more of the lateral directions and differences in dot columns 406 in one or more of the longitudinal directions between the print coordinates and the positioning information. (dot column difference is the minimum distance between two ink dots on the printing medium by the ink jet print head; in this embodiment, the horizontal dot column difference is from the rightmost side of the vertical positioning information to the leftmost side of the printed matter, and the vertical dot column difference is from the lowest end of the positioning information to the uppermost end of the printed matter.)

The tape multi-sensor printhead 134 may move in any manner over the print medium 202 and may be adapted for use with the present invention. Further description of these features is omitted here, and only movement at the same height above the print medium 202 is described as an example.

Preferably, as shown in fig. 2, in the present embodiment, the camera and auxiliary lighting assembly 136, the displacement sensor assembly 138, the distance measuring sensor assembly 140, and the like are mounted on the print head 134 with multiple sensors. The tape multi-sensor printhead 134 moves in elevation over the print medium 202. The printer intelligent control circuit 102 transmits an instruction to the camera and auxiliary lighting assembly 136 to shoot the printing medium 202 through the wired or wireless data link 152, and the camera and auxiliary lighting assembly 136 shoots and transmits shot picture data back to the printer intelligent control circuit 102 through the wired or wireless data link 152. The displacement sensor assembly 138 captures displacement data of the smart tape multi-sensor printhead 134 on the print medium 202, which is transmitted to the printer smart control circuit 102 via a wired or wireless data link 152. The ranging sensor assembly 140 measures gap data between the multi-sensor printhead and the print media 202 and communicates to the printer intelligent control circuitry 102 via a wired or wireless data link 152.

Preferably, as shown in FIG. 5, in this embodiment, the camera and auxiliary lighting assembly 136 takes three

pictures

502, 504, 506, respectively, in an equal "translational" motion with the multi-sensor print head 134 over the print medium 202. Assuming that the distance between the camera and auxiliary lighting assembly 136 and the print medium 202 remains constant, the length and width of the captured picture represent the distance M, N on the print medium 202. The picture 502 is moved from the position of the picture 504 to the position of the picture 502, moved laterally by X1 and moved longitudinally by Y1. The picture 502 and the picture 504 are spliced into a picture 512 according to well-known plane geometry principles. Moving from shot 504 to shot 506, moving laterally by X2-X1 distances and moving longitudinally by Y2-Y1 distances. The picture 512 is stitched with the picture 504 to form a picture 514 according to well-known plane geometry principles. The printer intelligent control circuit 102 sequentially splices the pictures according to the displacement data when the pictures are shot by adopting a rule that the pictures cover the pictures and the new pictures cover the old pictures. The printer intelligent control circuit 102 compares the stitched image 514 with the background image 302, the positioning information 304, and the print data (including the print content 402, the lateral dot column differences 404, the longitudinal electrical column differences 406, etc.) to identify the positioning information 304 and the printed content 508 on the print medium 202. If the multi-sensor print head 134 moves sufficiently far and the camera 136 takes enough pictures, the printer intelligent control circuit 102 can also recognize the unprinted content 510.

As shown in fig. 4, the differences between the printed content 508 "S" and the positioning information 304 in the horizontal and vertical dot columns are E1 and F1, respectively. The dot row difference rate R = distance/dot row difference. It is found that E1 xr = X2-P1+ P2, and F1 xr = Y2-Q1+ Q2.

Selected nozzles of printhead assembly 102 eject ink drops that "print" printed matter (including patterns, icons, forms, text, colors, etc.) onto a print medium.
