Abstract
The utility model relates to a reflected heat mode thermo stamping head, comprising a substrate, a heating element resistor arranged on the substrate, a metal lead wire, and a wear layer coated on the heating element resistor and the metal lead wire. The substrate is composed of a bottom layer, a metal layer and a glass-ceramics layer. The bottom layer, the metal layer and the glass-ceramics layer form the reflection structure of heat. Partial heat emitted by the heating element can be reflected on the wear layer through the reflection structure of heat. The utilization ratio of the heat of the heating element is enhanced. The unnecessary dissipation of the heat is decreased. Simultaneously, because the metal layer has a good thermal conductivity, the heat conducted by the heating element is conducted on the bottom layer in time, and the heat is conducted on a radiator through the bottom layer; the heat can be quickly emitted and the printing efficiency can be enhanced.
Description
Technical field
The utility model relates to the thermal printer head of a kind of heat sublimation, hot transfer printing, thermal printing mode, but particularly a kind of thermal printer head that has reverberation mode substrate.
Background technology
The structure of traditional thermal printer head has been a known technology, adopts the ceramic substrate of glazing or silicon chip as substrate usually, preparation heater resistance and metal lead wire on substrate, wear-resisting layer covering on heater resistance and metal lead wire.Heater resistance is introduced electric pulse by coupled drive circuit makes it send certain heat, and the heat that each heater sent sees through wearing layer through the heat conduction and is delivered on the thermal printing paper, the part variable color that thermal printing paper is heated, thus realize printing; When electric pulse stopped, the heat major part of the remnants of heater was transmitted to and the contacted radiator of substrate by the ceramic substrate of glazing or the substrate of silicon chip, and radiator distributes heat, and heated heater temperature descends.Because have only the heat that is delivered on the thermal printing paper through wearing layer to be only useful part, and be useless by the heat that substrate and heat sink radiates are fallen, if it is excessive that these useless heats are accumulated, can not distribute rapidly, then influence is normal prints, so all designers are in that to seek to design a kind of heat with heater more to the wearing layer conduction, and few more good more and to the conduction of substrate direction to substrate direction heat conduction efficiency height, fireballing printhead.Can find out that thus the print speed of thermal printer head depends on electrical pulse height that puts on the heater dot matrix and the time that applies, depend on the utilization rate of the heat that heater sends.
Along with the continuous development of hot print technology, more and more higher to the quality requirement of the image printed and photo, require also more and more higher to speed and definition.Along with the raising of electrical pulse amplitudes, the quickening of print speed, substrate can not conduct remaining heat rapidly, thereby substrate temperature is constantly raise, especially in the printhead that adopts thick film technology to make, because each layer thickness is bigger, latent heat is more, and this kind phenomenon is more outstanding.Along with the lengthening of time-write interval, substrate temperature constantly raises and normal printing has been caused influence in the printer use, and image that prints and photo thicken unclear gradually.At this moment, need shutdown cooling a period of time can arrive original state, but still can not work for a long time continuously, reduced printing effect, seriously affect the development of printing technique.
The aforementioned hot printhead is in wearing layer preparation, and numerous designers has spent for many years the time to seek fast, the wear-resisting material of heat conduction, and the life-span that printhead is printed on common paper and heat-sensitive paper has reached tens and even 100 kilometers.But entered for 20 end of the centurys, along with the application of thermal printer is further opened up extensively, common thermal printer head wearing layer exposes many drawbacks, only several kilometers of wearing layer life-spans that are used for the printhead that special tag prints, many designers are in the service life how research improve printhead by the abrasive resistance that improves wearing layer, and general way is additional again one, two tunics on original wearing layer.Report as following two pieces of Japanese patents of invention:
1, thick film printhead and manufacture method thereof (thick film サ-マ Le プ ト ヘ Star De and び そ manufacture method)
Publication number: the spy opens 2002-002006
Open day: on 01 08th, 2002
2, the manufacture method of thermal printing head (サ-マ Le ヘ Star De manufacture method)
Publication number: the spy opens 2002-178549
Open day: on 06 26th, 2002
Above-mentioned two patents are the manufacture methods that are used for studying the thermal printer head that covers one deck wearing layer material on former wearing layer again, though this method has improved the life-span of wearing layer, but, owing to increased the thickness of wearing layer, the heat that heater is sent can not be transmitted on the hot print paper timely, and the utilization rate of the heat that heater sends also reduces accordingly, and the power that printhead is consumed increases the printing effect variation.
Summary of the invention
The purpose of this utility model is exactly to solve the above-mentioned technical problem that exists in the prior art, but a kind of thermal printer head that has reverberation mode substrate that most of heat of heater can be transmitted to hot print paper,, long service life fast to the heat conduction velocity of substrate by wearing layer is provided.
For achieving the above object, thermal printer head of the present invention, comprise substrate and preparation thereon heater resistance, metal lead wire and cover wearing layer on heater resistance and the metal lead wire, described substrate is made up of bottom, metal level and glass-ceramic layer.
Described bottom can be ceramic layer or silicon layer, and described silicon layer can be a monocrystalline silicon, also can be polysilicon.
Described metal level is the metal platinum layer, perhaps is layer of titanium metal.
Described wearing layer is amorphous diamond carbon film (ta-c).
In the thermal printer head that the technical solution of the utility model constituted, bottom, metal level and glass-ceramic layer are formed the catoptric arrangement of heat, can reflex to by the catoptric arrangement of above-mentioned heat on the wearing layer from the part of the heater evolution of heat, improved the utilization rate of heater heat, reduced unnecessary heat and scattered and disappeared.Simultaneously,, the heat that comes from the heater conduction can be transmitted on the bottom timely, be transmitted on the radiator by bottom again, thereby heat is distributed rapidly, improved printing effect because metal level has good heat-conducting.
Because amorphous diamond carbon film and substrate have strong adhesive force, and have the hardness height, the characteristics that thermal conductivity is high so have the printhead long service life of this kind wearing layer, can adapt to flying print work.
Substrate organically combines with wearing layer, can make thermal printer head have the advantage of low-power consumption, printing speed, long time continuous working.
