Abstract
The utility model relates to the technical field of the bar code printer, especially relates to a thermal print head of a bar code printer, which comprises a radiation base, a ceramic substrate and a print circuit board fixedly connected with the radiation base, wherein the print circuit board is arranged on one side of the ceramic substrate, a top surface of the print circuit board is lower than the top surface of the ceramic substrate, and the top surface of the print circuit board is fixedly connected with an integrated circuit. The structure of the thermal print head is scientific and simple, the size of the structure is relatively small, a gap is formed between the ceramic substrate and the print circuit board, the height of an encapsulated encapsulation layer is reduced and the thermal print head is suitable for a relatively large printer rubber roller and facilitates the product miniaturization.
Description
Technical field
The utility model relates to the bar code printer technical field, relates in particular to a kind of thermal printing head of bar code printer.
Background technology
Bar code printer is called bar-code printer again, is a kind of printer of special use, and its institute's printed contents is generally brand identity, sequence number sign, packaging label, bar code identification, envelope label, clothes drop of enterprise etc.The most important parts of bar code printer are printheads, and printhead is to be made up of thermistor, and the process of printing is exactly that the thermistor heating is transferred to the process on the paper with the carbon dust on the carbon ribbon.
The ceramic substrate of existing thermal printing head is identical with the printed wire plate thickness, causes the height of the encapsulated layer after printed substrate encapsulates bigger, is unfavorable for the product miniaturization.
Summary of the invention
The purpose of the utility model is exactly the thermal printing head that a kind of bar code printer is provided to the deficiency of prior art existence, and its scientific structure is simple, and volume is less, goes for bigger printer rubber roll.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of thermal printing head of bar code printer, comprise radiating seat, and be fixedly connected with ceramic substrate, printed substrate on the said radiating seat; Said printed substrate is positioned at a side of said ceramic substrate; Be provided with heater circuit in the said ceramic substrate, this heater circuit is connected with said printed substrate through spun gold, and the last end face of said printed substrate is fixedly connected with integrated circuit; Said integrated circuit and said gold thread are provided with encapsulated layer, and the last end face of said printed substrate is lower than the last end face of said ceramic substrate.
The last end face of said encapsulated layer is not higher than the last end face of said ceramic substrate.
Said radiating seat is provided with boss, and said ceramic substrate is arranged on the said boss.
The thickness of said ceramic substrate is than the thicker of said printed substrate.
Said ceramic substrate and said radiating seat are bonding.
Said printed substrate and said radiating seat are bonding.
Said integrated circuit and said printed substrate are bonding.
The utility model beneficial effect is: the utility model comprises radiating seat, is fixedly connected with ceramic substrate, printed substrate on the said radiating seat, and said printed substrate is positioned at a side of said ceramic substrate; The last end face of said printed substrate is lower than the last end face of said ceramic substrate; The last end face of said printed substrate is fixedly connected with integrated circuit, and the utility model scientific structure is simple, and volume is less; Be formed with a step between ceramic substrate and the printed substrate; Reduce the height of encapsulation back encapsulated layer, gone for bigger printer rubber roll, be convenient to the product miniaturization.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
embodiment one.
The thermal printing head of a kind of bar code printer of the utility model; Like Fig. 1, shown in Figure 2, it comprises radiating seat 1, is fixedly connected with ceramic substrate 2, printed substrate 3 on the said radiating seat 1; Said printed substrate 3 is positioned at a side of said ceramic substrate 2; Be provided with heater circuit in the said ceramic substrate 2, this heater circuit is connected with said printed substrate 3 through spun gold, and the last end face of said printed substrate 3 is fixedly connected with integrated circuit 4; Said integrated circuit 4 is provided with encapsulated layer 5 with said gold thread, and the last end face of said printed substrate 3 is lower than the last end face of said ceramic substrate 2.The utility model scientific structure is simple; Volume is less; Be formed with a step between ceramic substrate 2 and the printed substrate 3, reduced the height of encapsulation back encapsulated layer 5, thereby increased the distance of rubber roll 6 to encapsulated layer 5; Can make the thermal printing head of the utility model be applicable to bigger printer rubber roll 6, be convenient to the product miniaturization.
Further, the last end face of said encapsulated layer 5 is not higher than the last end face of said ceramic substrate 2.
Further, as shown in Figure 2, said radiating seat 1 is provided with boss 11, and said ceramic substrate 2 is arranged on the said boss 11, and said printed substrate 3 is arranged at said boss 11 times, thereby has reduced the height of end face on the printed substrate 3.
For the utility model, said ceramic substrate 2 and said radiating seat 1 are bonding, and said printed substrate 3 and said radiating seat 1 are bonding, and said integrated circuit 4 and said printed substrate 3 are bonding.
embodiment two.
As shown in Figure 3, present embodiment is with the different of embodiment one: the thickness of said ceramic substrate 2 is than the thicker of said printed substrate 3, and printed substrate 3 is because thinner thickness, can realize that also end face on it is lower than the last end face of said ceramic substrate 2.
The other technologies characteristic of present embodiment is identical with embodiment one, repeats no more at this.
Should be noted that at last; Above embodiment is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain, although with reference to preferred embodiment the utility model has been done explanation at length, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the essence and the scope of the utility model technical scheme.
