Description

Printing head device with multiple sensors

Technical Field

The invention belongs to the technical field of printing, particularly relates to an intelligent printing technology, and relates to a printing head device in a printer.

Background

In the known prior art, a printing head in a printer is simple in structure, and the printing of a printing medium is mostly realized by adopting technologies such as electromagnetism, electric heating and photoelectricity. Printers are known to be positioned by way of a side edge of the print media, a positioning strip, a positioning hole, and the like. It is assumed that the print medium already carries the background pattern before this printing. 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 existing printer has no perception capability on a printing medium and the content thereof, a plurality of steps need manual intervention or adjustment in advance, and the rate of waste of printed products is high. Not only can cause the waste of materials, but also takes trouble, wastes time and labor, has high requirement on the skill quality of printing personnel, and increases the labor cost, the material cost and the time cost. There is therefore a need for an effective solution to address the above-mentioned problems.

Disclosure of Invention

The invention provides a printing head device with multiple sensors, which can enable a printer to sense a printing medium and the content thereof and formulate a printing scheme without manual intervention or adjustment in advance, thereby saving labor cost, material cost and time cost and improving user experience.

The technical scheme of the invention is as follows: a printing head device with multiple sensors comprises a printing head assembly, a camera, an auxiliary lighting assembly, a displacement sensor assembly, a distance measuring sensor assembly, an acceleration sensor assembly and the like. The camera and the auxiliary lighting assembly comprise a lens, a photosensitive sensor, auxiliary lighting, a lens cone, a transparent screen, a reflecting plate and the like. The displacement sensor assembly comprises a lens, a displacement sensor chip and the like.

Furthermore, the invention is characterized in that:

the data of the obtained printing medium and the content thereof, such as a camera, an auxiliary lighting assembly, a displacement sensor assembly, a distance measuring sensor assembly and the like on the printing head device with the multiple sensors, are transmitted to a main control circuit of the printer through a printing head data link. The acceleration sensor assembly will obtain physical space acceleration data for the printhead device with the multiple sensors and transmit the data to the printer master control circuit via the printhead data link. The main control circuit of the printer formulates a printing scheme, and drives the print head device moving mechanism, the print medium moving mechanism and the print head assembly of the multi-sensor to complete the printing action through the driving circuit.

Further, in the present invention, the camera, the auxiliary lighting assembly, the displacement sensor assembly, the distance measuring sensor assembly, the acceleration sensor assembly, and the like are mounted on the print head device with multiple sensors and move together with the print head device with multiple sensors.

Furthermore, the camera, the auxiliary lighting assembly, the displacement sensor assembly, the distance measuring sensor assembly, the printing head assembly and the like are arranged on the same side of the printing head device with the multiple sensors.

Further, the external print head contact point is independently installed on one side of the multi-sensor print head device different from the camera head and auxiliary lighting assembly, the displacement sensor assembly, the distance measuring sensor assembly and the print head assembly.

Furthermore, the camera and the auxiliary lighting assembly shoot the printing medium, and the obtained picture data are transmitted to the main control circuit of the printer through the printing head data link.

Further, the displacement sensor assembly acquires displacement data of the printing head device with the multiple sensors on the printing medium, and transmits the displacement data to the printer main control circuit through the printing head data link.

Further, the distance measuring sensor assembly measures the print head device with the multiple sensors and the print medium to obtain gap data, and transmits the gap data to the main control circuit of the printer through the print head data link.

Furthermore, the acceleration sensor assembly measures the posture of the printing head device with the multiple sensors, obtains physical space acceleration data, and transmits the physical space acceleration data to the main control circuit of the printing machine through the printing head data link.

Further, the printer main control circuit measures and splices the pictures according to the picture data, the displacement data and the gap data which are sent back by the printing head device with the multiple sensors, and compares, identifies and positions the pictures with the printing content data, the background pictures and the positioning information. So as to plan the printing scheme before printing, monitor the printing effect during printing and confirm the qualified products after printing.

Further, the printer main control circuit drives and adjusts the gap between the printing head assembly and the printing medium according to the gap data.

Further, the printer main control circuit converts the moving direction and speed data (including acceleration data) of the printing head device with the multiple sensors relative to the printing medium according to the displacement data of the displacement sensor assembly.

Further, the printer main control circuit converts the physical space acceleration data obtained by the acceleration sensor assembly, the initial speed of the printing head device with the multiple sensors and the initial movement direction of the printing head device with the multiple sensors into the movement direction and the speed data of the printing head device with the multiple sensors relative to the physical space.

Furthermore, the printer main control circuit corrects the driving parameters of the printing head assembly according to the moving direction and speed data of the printing head device with the multiple sensors relative to the physical space and the gap data obtained by the distance measuring sensor assembly.

Further, the printer main control circuit further corrects the driving parameters of the printing head assembly according to the moving direction and the speed data (including the acceleration data) of the printing head device with the multiple sensors relative to the printing medium.

Furthermore, the printing machine main control circuit can make the printing scheme more elaborate by correcting the driving parameters of the printing head component; the printing head device with multiple sensors and the motion control of | or printing media can be more rapid, and the printing effect is more exquisite.

Compared with the prior art, the invention has the beneficial effects that: in the invention, the printer head device with multiple sensors is provided with the camera, the auxiliary lighting assembly, the displacement sensor assembly, the distance measuring sensor assembly, the acceleration sensor assembly and other sensors, so that the printer has sensing capability on a printing medium, the content thereof and the like. The printing positioning mode of the printer is diversified. Through comparing, identifying and positioning with the printing content data, the background picture and the positioning information, a printing scheme is formulated without manual intervention or adjustment in advance, so that the labor cost, the material cost and the time cost are saved, and the user experience is improved.
