Description

Technical Field

[0001] This invention relates to the field of thermal printer technology, and in particular to a printer structure with electrostatic conductivity and its intelligent control method. Background Technology

[0002] In practical applications of thermal printers, static electricity and print quality degradation have long affected equipment performance and user experience. Current technology requires multiple independent components to achieve static conductivity in thermal printers, leading to cumbersome assembly processes, low production efficiency, increased component procurement and assembly costs, and hindering large-scale production. Furthermore, existing thermal printers have a design flaw where the thermal substrate bulges outwards. When the substrate undergoes inward deformation, the spring structure in the center cannot provide sufficient restoring force to return it to a flat state, resulting in faint print quality. This severely impacts print quality, necessitates frequent downtime for maintenance or component replacement, increasing user costs and maintenance complexity.

[0003] To address the shortcomings of the existing technologies, this invention proposes a printer structure that integrates electrostatic conductivity and print quality restoration functions. By optimizing component design and connection relationships, the structure is simplified while solving two technical pain points, demonstrating significant practicality and economy.

[0004] Therefore, the existing technology of thermal printers needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a printer structure with electrostatic conductivity and its intelligent control method. By optimizing the design and connection of components, the structure is simplified while solving two technical pain points, which has significant practicality and economy.

[0006] To achieve the above objectives, the present invention adopts the following solution: A printer structure with electrostatic conductivity includes a power output component, a transmission connector, an elastic reset component, a thermal printing core component, and an electrostatic discharge component. The power output component is drivenly connected to the transmission connector, which cooperates with both the elastic reset component and the thermal printing core component, and is also electrically connected to the electrostatic discharge component. Electrostatic conductivity is achieved through the cooperation of the transmission connector, the power output component, and the electrostatic discharge component, and print quality is restored through the cooperation of the transmission connector, the elastic reset component, and the thermal printing core component.

[0007] Furthermore, the power output component is a connecting motor, and the output shaft of the connecting motor is fixedly connected to the transmission connector to provide driving force to the transmission connector.

[0008] Furthermore, the transmission connector is a moving blade plate, which has a long strip structure. One end of the moving blade plate is connected to the power output component, and the other end abuts against the thermal printing core component. The middle area of ​​the moving blade plate is elastically connected to the elastic reset component.

[0009] Furthermore, the elastic reset component is a spring, one end of which is fixed to the transmission connector and the other end is detachably connected to the printer frame. The spring is in a pre-compressed state, providing the transmission connector with an elastic force toward the thermal printing core component.

[0010] Furthermore, the core component of the thermal printing is a thermal sheet assembly, which includes a substrate and a thermal printing layer disposed on the surface of the substrate. The transmission connector abuts against the side of the substrate away from the thermal printing layer, and when the substrate undergoes concave deformation, the transmission connector can push the substrate back to a flat state under the action of the elastic reset component.

[0011] Furthermore, the electrostatic discharge component is a motor assembly, which includes a metal housing and a grounding wire. The transmission connector is in conductive contact with the metal housing. One end of the grounding wire is connected to the metal housing, and the other end is connected to the external grounding terminal of the printer, forming an electrostatic discharge circuit.

[0012] Furthermore, the moving blade plate is provided with a conductive coating, and the conductive coating is made of a silver-copper alloy.

[0013] Furthermore, the substrate of the thermal sheet assembly is provided with a positioning groove, and the end of the transmission connector is provided with a protruding part that matches the positioning groove. The protruding part is embedded in the positioning groove to achieve precise positioning and engagement between the transmission connector and the substrate.

[0014] Furthermore, the metal casing of the motor assembly is provided with elastic conductive contacts made of beryllium copper. The elastic conductive contacts are in elastic contact with the transmission connector, ensuring that the transmission connector maintains a conductive connection with the metal casing during movement. It also includes a rubber roller assembly, which is positioned opposite to the thermal printing core component. When the rubber roller assembly presses against the thermal printing core component, it generates pressure on the thermal printing core component towards the transmission connector, increasing the contact pressure between the transmission connector and the static discharge component, thus improving the stability of static electricity conduction.

[0015] An intelligent control method includes the following steps: S1. Real-time monitoring: During printer operation, the voltage sensor collects the contact voltage value between the electrostatic discharge component and the transmission connector, the pressure sensor collects the contact pressure value between the transmission connector and the thermal printing core component, and the image acquisition module captures the printed sample image output by the thermal printing core component. S2. Data Judgment: Compare the collected contact voltage value with the preset voltage threshold. If the contact voltage value is higher than the preset voltage threshold, it is determined that the electrostatic conduction is abnormal. Compare the collected contact pressure value with the preset pressure threshold. If the contact pressure value is lower than the preset pressure threshold, it is determined that the printing effect repair capability is insufficient. Perform grayscale analysis on the printed sample image. If there are three or more consecutive areas in the image with grayscale values ​​lower than the preset grayscale threshold, it is determined that the printing is faint. S3. Intelligent Adjustment: If an abnormal electrostatic conduction is detected, the power output component is controlled to drive the transmission connector to move closer to the electrostatic discharge component until the contact voltage drops below the preset voltage threshold. If the printing effect repair capability is insufficient, the pre-compression amount of the elastic reset component is increased by 5%-10% until the contact pressure reaches the preset pressure threshold. If a faint printing phenomenon is detected, the transmission connector is first controlled to move back and forth 2-3 times on the substrate surface of the thermal printing core component to correct the concave deformation, and then the rubber roller assembly is controlled to increase the pressing force on the thermal printing core component by 10%-15% until the gray value of the printed sample image meets the requirements. S4. Closed-loop feedback: After completing the intelligent adjustment, continuously collect the contact voltage value, the contact pressure value, and the printed sample image. If the data collected for 5 consecutive times meets the preset threshold requirements, the adjustment is stopped and the current adjustment parameters are recorded. If there are still abnormalities, repeat step 3 until the data meets the requirements, and at the same time generate an abnormality log and store it in the printer control module.

[0016] In summary, the advantages of this invention over the prior art are: This invention addresses the shortcomings of existing thermal printer technology. Through its structural design, it offers the following advantages: simplified structure and reduced cost. By integrating power output, transmission, static electricity discharge, and reset functions into a few core components, it reduces the number of parts in traditional static electricity conduction structures, simplifies assembly processes, lowers production and maintenance costs, and improves production efficiency. Dual-function integration simultaneously achieves static electricity conduction and print quality repair, eliminating the need for separate static electricity elimination devices and print repair mechanisms, saving internal space and increasing equipment integration. Improved stability and reliability effectively solve the problem of faint printing and reduce equipment failure rates. Intelligent adaptive adjustment, through real-time monitoring and closed-loop feedback control, automatically identifies and resolves static electricity anomalies and print quality issues, reducing manual intervention and improving the equipment's intelligence and ease of use. Furthermore, its simple structure makes it convenient to use. Attached Figure Description

If a faint print is detected, the transmission connector 200 is first moved back and forth 2-3 times on the substrate surface of the thermal printing core component 500 to correct the concave deformation, and then the rubber roller assembly is increased by 10%-15% in the pressing force on the thermal printing core component 500 until the grayscale value of the printed sample image meets the requirements. S4. Closed-loop feedback: After completing the intelligent adjustment, continuously collect the contact voltage value, the contact pressure value, and the printed sample image. If the data collected for 5 consecutive times meets the preset threshold requirements, the adjustment is stopped and the current adjustment parameters are recorded. If there are still abnormalities, repeat step 3 until the data meets the requirements, and at the same time generate an abnormality log and store it in the printer control module.
