The braille translation refers to a translation process of converting common text information into braille information organized according to the braille rule. The Braille printed matter is a special reading matter printed with Braille convex points for the blind to touch and read, is an important tool for the blind to understand things, and is large in the quantity base number of blind groups in China, but resource application such as Braille labels, label printing and the like is quite deficient. Some braille printers in the prior art have large volumes, are inconvenient to carry and have very limited application, so that the design of a portable braille printing device has important significance.

Disclosure of Invention

The portable electromagnetic dot matrix braille printing device is convenient to convert braille, small in size, high in portability and beneficial to carrying and using.

In order to solve the technical problems, the invention adopts the technical scheme that:

a portable electromagnetic type dot matrix braille note printing device comprises a machine body, a controller and a plurality of printing contact points, wherein the machine body comprises an upper cover and a lower cover which can be covered, a middle partition plate is arranged between the upper cover and the lower cover, and the upper cover, the middle partition plate and the lower cover are hinged at the same side; the printing contacts are arranged on the lower cover in an array form and are covered by the middle partition plate; the middle partition plate is provided with a plurality of through holes, and the through holes correspond to the printing contacts one to one; the printing contact is controlled by the controller, and the braille printing is carried out by movably penetrating through the through hole. The printed contact pitch arrangement pitch is specified by the braille standard.

When the Braille note printing device is used, a note with matched size is placed on the middle partition plate, the upper cover is closed, then printing content is input into the controller, the controller drives the corresponding printing contact protrusions in the array after analysis processing, the note is stamped through the through holes of the middle partition plate, Braille convex points are formed on the surface of the note, and Braille note printing is completed.

As one preferable scheme, the controller comprises an input unit for inputting printing information, an electromagnetic driving unit for driving printing contact operation and a control unit, wherein the control unit is electrically connected with each unit, analyzes and processes information data in a centralized manner and issues an operation instruction; the control unit is also connected with a power supply unit. Wherein, the power supply unit provides the energy supply for the whole device. The user inputs the information through the input unit, the control unit analyzes the content and converts the content into Braille codes, the Braille codes are further converted into electric signals, and the electromagnetic driving unit controls the corresponding printing contact protrusions to complete Braille note printing. The electromagnetic driving unit is an electromagnetic driver, and the control unit is a controller with an Ardiuno chip as a core.

As one preferable scheme, the printing contact comprises a contact rod, a limiting mechanism and a base, the contact rod is vertically arranged on the base, a convex block is arranged in the middle of the contact rod, and a contact spring is compressed below the convex block; the limiting mechanisms are fixed on the base and symmetrically distributed around the contact rod to limit the protrusion and the falling of the contact rod. When the limiting mechanism does not press the bump, the contact rod is raised upwards by the vertically upward elastic force of the contact spring to be stamped; after the stamping is finished, the limiting mechanism presses the convex block again, and the contact rod compresses the contact spring to finish the resetting.

As one preferable scheme, the limiting mechanism comprises a bracket, limiting claws and an electrified coil, the bracket is erected on two opposite sides of the contact rod, and the limiting claws are rotatably arranged on the bracket and used for pressing the contact rod convex blocks; the electrified coil is arranged right below the limiting claw and is communicated with the controller; the limiting claw is a magnetic part, and the energizing coil is energized to generate a magnetic field with the same magnetism as the limiting claw.

As one of the preferred scheme, the limiting claw is sleeved with a reset snap spring. The reset snap spring is used for facilitating the limiting claw to rotate and reset, and the convex block is pressed again when the electrified coil is powered off.

As one preferable scheme, the top surface of the limiting claw is further provided with a rotation stopping block for limiting the rotation angle of the limiting claw. The rotation stopping block is used for limiting the rotation angle of the limiting claw, and ensures that the limiting claw still abuts against the convex block of the contact rod when in a non-pressing state, so that the convex block is pressed again.

As a preferable scheme, the input unit is a voice input unit or a text input unit. Generally, an existing voice input unit is used, the voice input unit has a voice recognition function, a user inputs voice through voice control, then confirms printing through voice control, and voice content is converted into an electric signal to be output through a series of program processing of a control unit, such as a braille database, coding processing and Chinese blind conversion.

Preferably, the control unit is further connected to a storage unit for storing information data. The storage unit is mainly used for storing the existing data such as braille data and historical data.
