preparation example Construction

[0055] The invention also provides a preparation method of the thermal printing head.

[0056] see Image 6 , the preparation method of the thermal printing head in an embodiment, comprises the following steps:

[0057] S11: Printing a heating resistor on the substrate to form a heating resistor band.

[0058] Specifically, a heating resistance layer is printed on the substrate to form a heating resistance band. In one embodiment, the common electrodes and the individual electrodes are printed on the substrate first, and then the heating resistors are printed to cover the common electrodes, the individual electrodes and the substrate in the area between the common electrodes and the individual electrodes to form a heating resistor strip.

[0059] S12: Print the bus electrode above the substrate in the lateral direction of the heating resistor, and print the bus electrode from the initial printing surface lower than the heating resistor until the height of the bus electrode r...

Abstract

The invention provides a bus electrode framework, a thermosensitive printing head and a preparation method of the thermosensitive printing head. The bus electrode framework comprises a base plate, a bus electrode, a heating resistor, a heating resistor protective layer and a bus electrode protective layer. The bus electrode is arranged on the base plate, the heating resistor and the bus electrodeare transversely arranged on the base plate together, and the heating resistor is covered with the heating resistor protective layer. The bus electrode is covered with the bus electrode protective layer, the thickness of the bus electrode is larger than that of the heating resistor, and the upper surface of the bus electrode and the upper surface of the heating resistor are located on the same plane. The plane where the lower surface of the bus electrode is located is lower than the plane where the lower surface of the heating resistor is located, the thickness of the bus electrode is increased, and the position and the structure of the bus electrode protective layer above the bus electrode do not need to be changed, so that the size of the thermosensitive printing head is not increased; and the abrasion resistance of the bus electrode protective layer and the heating resistor protective layer can further be improved, and the lives of the bus electrode and the heating resistor are prolonged.

Description

technical field [0001] The invention relates to the technical field of thermal printers, in particular to a bus electrode structure, a thermal print head and a method for preparing the thermal print head. Background technique [0002] In a thermal printer, one of the most important components is a thermal print head equipped with a linear heating resistor. When working, the printing medium is pressed against the heating resistor by the pressure roller, and the heating resistor on the thermal printing head can selectively generate heat according to whether it is energized, so that the printing medium in contact with the thermal printing head heating resistor has a selective color reaction , at the same time, the cylindrical pressure roller rotates around the axis to realize the conveyance of the printing medium. [0003] An important structure of the thermal print head is the bus electrode. The bus electrode is used to combine the current flowing through the heating resistor...
