Abstract

The invention relates to a thermo-sensitive printing head, in particular to a thermo-sensitive printing head for automatic deposited carbon removal and a manufacturing method. The thermo-sensitive printing head for automatic deposited carbon removal comprises a ceramic substrate with ground glaze, several lead electrodes, common lead electrodes and a protrusion-shaped heating body formed in the main scanning direction, wherein the several lead electrodes and the common lead electrodes are formed on the substrate, the heating body is used as a center to stick dry films at the positions different distances away from the center position in the auxiliary scanning direction, and a deep grove is formed in the upper portion of the heating body. Two layers of glass frit is coated in the groove, a grinding layer is formed after glass sintering, very steep segment difference is formed at the end of the grinding layer after grinding planarization, and protective films are formed on the grinding layer and the lead electrodes. The thermo-sensitive printing head is characterized in that the grinding layer is arranged at the upper portion of the heating body, the grinding layer is subjected to planarization treatment, the paper outlet side, namely the common lead electrode side, is longer, the large segment difference is formed at the end of the grinding layer, produced paper scraps are effectively pushed from the heating body to the position of the segment difference by means of the structure, and the thermo-sensitive printing head can automatically remove deposited carbon.

Description

Technical field

[0001] The patent of the present invention relates to a thermal printing head, in particular to a printing head with a flattened structure of the protrusions of the heating element and effectively eliminating the influence of carbon deposits and a manufacturing method thereof. Background technique

[0002] As we all know, the thermal print head includes a substrate made of insulating material, a base layer (underglaze glass) is made on the substrate, and then lead electrodes are formed on the surface of the substrate and the base layer. The lead electrodes are divided into individual electrodes and common electrodes, on the lead electrodes The heating resistor strip formed along the main printing direction, one end of the individual electrode is connected to the heating resistor strip along the secondary printing direction, the other end is connected to the control IC, and one end of the common electrode is connected to the heating resistor strip along the secondar...
