Description

A kind of type matrix supporting construction of smart card stamp device

Technical field

This utility model relates to smart card and manufactures equipment, and the type matrix being specifically related to a kind of smart card stamp device supports knot Structure.

Background technology

In smart card production process, smart card stamp device is for stamping character code on the surface of card, and it mainly wraps Including code-disc and type matrix beats mechanism, wherein, described code-disc includes code-disc, lower code-disc and code-disc drive mechanism, described upper code Dish and lower code-disc are usually disc structure, and in horizontal positioned, described upper code-disc and lower code-disc include encoder basement, the circle of encoder basement It is arranged with the type matrix being oppositely arranged in circumferential direction, between the type matrix being oppositely arranged under normality, there is gap, treat stamp for receiving Card, during stamp, two type matrixes beat mechanism and tap a pair type matrix in code-disc and lower code-disc simultaneously, and two type matrixes are transported relatively Dynamic, the card being pointed between two type matrixes clashes into, and the character code in type matrix is got on card；After stamp, two type matrixes It is reset to its normal orientation.In order to allow type matrix be maintained at fixing position under normal conditions, code-disc needs arrange type matrix supporting construction, This type matrix supporting construction is generally elastic support structure, and common elastic support structure is made up of a support plate and spring, described Propping up support plate to be connected with encoder basement by spring, this support plate is disc structure, and its edge acts on the afterbody of type matrix afterbody On step, the elastic force that support plate produces is promoted a support plate that type matrix is maintained at its normal orientation by described spring, type matrix when stamp, All the time being supported the resilient force that dish applies, once type matrix beats mechanism and unclamps type matrix, and type matrix just automatically resets.Existing Above-mentioned type matrix supporting construction has the disadvantage that

Whole support dish run-off the straight beat during stamp, not only working resistance is big, and require a support plate and code-disc frame it Between attachment structure be necessary to ensure that support plate all can beat flexibly in each position so that structure is complicated, and installation difficulty is big, together Time the parts that comprise the most, manufacturing cost is high.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the type matrix of a kind of smart card stamp device props up Support structure, this type matrix supporting construction has simple in construction, easy for installation, working resistance is little, parts are few, low cost and other advantages.

The purpose of this utility model is realized by following technical scheme:

The type matrix supporting construction of a kind of smart card stamp device, including being arranged on a support plate of encoder basement central authorities and being located at Propping up the support shell fragment in support plate outer rim, the quantity of described support shell fragment is equal with the quantity of type matrix, and this support shell fragment is circumferentially Direction is uniformly distributed and is connected on a support plate, and each support shell fragment extends radially outward at the outer rim of a support plate, each Support shell fragment outer end elastic compression on the afterbody step of type matrix afterbody, the elastic force direction that type matrix is produced by this support shell fragment and The stamp of type matrix is in opposite direction；The head of each type matrix is provided with head step, and under normality, type matrix is produced by described support shell fragment Elastic force promotes the head step of type matrix to be pushed against on the end face of encoder basement.

The type matrix supporting construction of smart card stamp device of the present utility model, wherein, described support shell fragment with a support plate is Integral structure, this structure, compared with split-type structural, is processed convenient, and eliminates between support shell fragment and a support plate Attended operation；Adding man-hour, the surrounding a steel disc mills multiple empty portions radially extended and can be formed Support shell fragment.

The type matrix supporting construction of smart card stamp device of the present utility model, wherein, the outer end of described support shell fragment is provided with The expansion section of sharply changing section, the area of this expansion section is more than the area of the afterbody step of type matrix.Its object is to so that supporting bullet Sheet can fully contact with the afterbody step of type matrix, improves reliability.

The type matrix supporting construction of smart card stamp device of the present utility model, wherein, during the central authorities of described support plate are provided with Central hole, this centre bore is placed on outside the rotating shaft of code-disc；Described support plate is fixed by screws on the end face of encoder basement.By above-mentioned Structure so that the rotating shaft on code-disc passes smoothly from support plate, and realize a support plate and be connected with the fixing of encoder basement.

The type matrix supporting construction of smart card stamp device of the present utility model, wherein, under normality, described support shell fragment is on edge Axially towards the direction inclination and offset of offside type matrix while extending radially outwardly, this axial dipole field makes to support shell fragment often There is under state axial pretension elastic force so that type matrix may remain in its normal orientation.

Operation principle of the present utility model is: under normality (during not coding), and the outer end elastic compression of each support shell fragment exists On the afterbody step of type matrix afterbody, the elastic force direction that type matrix is produced by support shell fragment is in opposite direction with the stamp of type matrix so that word The head step of mould is pushed against on the end face of encoder basement, thus allows type matrix maintain its normal orientation；When carrying out stamp, two words Mould beats mechanism and taps a pair type matrix in upper code-disc and lower code-disc along stamp direction simultaneously, thus overcomes the bullet supporting shell fragment Power so that two type matrixes clash into card simultaneously and realize stamp, when type matrix beat mechanism along stamp direction opposite direction reset time, institute Stating support shell fragment promotes type matrix Rapid reset to its normal orientation the elasticity of type matrix.

This utility model compared with prior art has a following beneficial effect:

1, whole supporting construction is made up of a support plate and support shell fragment, and parts are few, and prop up between support plate and encoder basement Attachment structure is simple, only need to be fixed on encoder basement by a support plate, assembling simplicity, low cost of manufacture.

2, during stamp, only one of which supports shell fragment work, it is not necessary to whole support dish run-off the straight so that working resistance is little, joint Save power.
