Thermal printing head suitable for optical disc printing

Abstract

The utility model discloses a thermal printing head suitable for compact disc printing, and belongs to the technical field of thermal printing heads. The arc-shaped glass glaze is arranged at the bottom of a ceramic substrate, the packaging resin is used for packaging and protecting a driving chip, a heating body is arranged at the bottom of the side of the glass glaze, the included angle between the tangent line of the position where the heating body is located and the extension line of the ceramic substrate is 5-30 degrees, and a rolling shaft used for conveying a medium optical disc is arranged below the heating body. And the ceramic substrate is positioned on the printing head body which is obliquely arranged. The beneficial effects of the utility model are that the included angle between the tangent line of the position where the heating body is located and the extension line of the ceramic substrate is 5-30 degrees, so that the printing head needs to be installed on the printer in an inclined manner, and the medium optical disc can not interfere with packaging resin on the basis of ensuring the tight contact between the rolling shaft and the printing head, thereby the medium optical disc can not deform in the printing process, and the printing quality is improved. The printing quality is ensured, and the medium optical disk is not damaged.

Description

Technical Field

[0001] The utility model relates to a thermal printing head suitable for CD printing, belonging to the technical field of thermal printing heads. Background Art

[0002] The existing thermal print heads are basically flat-pressed structures. Due to the height of the encapsulated resin on the print head, the print medium and the encapsulated resin interfere with each other, causing the print medium to deform during movement (such as Figure 1-2 As shown), only deformable media, such as thermal paper and washable labels, can be printed, but hard, non-deformable media, such as CDs, cannot be printed, so there are limitations to printing. Utility Model Content

[0003] In order to solve the defects of the prior art, the purpose of the utility model is to provide a thermal print head suitable for CD printing which breaks through the printing limitation.

[0004] The technical solution of the utility model is: a thermal print head suitable for CD printing, including an arc-shaped glass glaze arranged at the bottom of a ceramic substrate, and a packaging resin for packaging and protecting a driver chip, a heating element is arranged at the bottom of the glass glaze side, and the angle between the tangent line of the heating element and the extension line of the ceramic substrate is 5-30 degrees, a roller for transmitting a medium CD is arranged below the heating element, and the ceramic substrate is located on a print head body arranged obliquely.

[0005] The bottom height of the packaging resin is higher than the height of the heating element.

[0006] The roller is in contact with the heat generating element.

[0007] The beneficial effect of the utility model is that the tangent line of the heating element and the extension line of the ceramic substrate exist at an angle of 5-30 degrees, so that the print head needs to be installed on the printer at an angle, and on the basis of ensuring that the roller and the print head are in close contact, the medium disc can not interfere with the packaging resin, so that the medium disc will not be deformed during the printing process, thereby ensuring the printing quality and not damaging the medium disc.

[0013] The following is combined with Figure 3-4 The utility model is further described as follows:

[0014] A thermal print head suitable for CD printing, comprising an arc-shaped glass glaze 2 arranged at the bottom of a ceramic substrate 1, and an encapsulation resin 3 for encapsulating and protecting a driving chip, a heating element 4 is provided at the bottom of the glass glaze 2, and the angle between the tangent line of the heating element 4 and the extension line of the ceramic substrate 1 is 5-30 degrees, a roller 6 for transmitting a medium CD 5 is provided below the heating element 4, the roller 6 is in contact with the heating element 4, and when the medium CD 5 passes by, the heating element 4 can fully contact with the medium CD 5 to ensure the printing effect, the ceramic substrate 1 is located on an inclined print head body 7, and the bottom height of the encapsulation resin 3 is higher than the height of the heating element 4, so that the medium CD passes through the bottom of the encapsulation resin 3 without interference and the medium CD will not be deformed.

[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
