[0043] Please refer to Figures 1 to 11 , and now a braille dot printer provided by an embodiment of the present utility model will be described. Please further refer to Figure 1 , Figure 2 andFigure 3, the braille dot printer provided by the embodiment of the present utility model includes a carrying platform 1, a printing module 5 and a moving mechanism. The carrying platform 1 is used to carry the paper 2 on which braille dots can be printed. The printing module 5 includes a printing head 51 for printing braille squares on the paper 2 and a driving mechanism 52 for driving the printing head 51 to move in the Z-axis direction. The printing head 51 is connected to the driving mechanism 52. The moving mechanism is used to drive the driving mechanism 52 to perform two-dimensional movement on a two-dimensional plane parallel to the paper 2. The moving mechanism includes a first moving module 3 capable of driving the driving mechanism 52 to move in the Y-axis direction and a second moving module 4 capable of driving the driving mechanism 52 to move in the X-axis direction. At least two printing modules 5 are arranged side by side on the moving mechanism. The moving mechanism composed of the first moving module 3 and the second moving module 4 can drive at least two printing modules 5 to perform two-dimensional movement synchronously on a two-dimensional plane parallel to the paper 2. At the same time, at least two driving mechanisms 52 can drive the corresponding printing heads 51 to move in the Z-axis direction, so as to realize that at least two printing heads 51 perform the actions of synchronously printing braille bumps and retracting after printing during the three-dimensional movement. Among them, the number A of the printing modules 5 is less than or equal to the number B of the braille squares printed in each row on the paper 2, and the distance between two adjacent printing modules 5 is a positive integer multiple of the distance between two adjacent braille squares. It should be noted that the number A of the printing modules 5 arranged on the moving mechanism can be 2, 3, 4 or more than 5. The distance between two adjacent printing modules 5 is 1 times, 2 times or more than 3 times the distance between two adjacent braille squares. The paper 2 is the paper 2 for braille printing. When printing braille dots with the braille dot printer, the number A of the printing modules 5 to be used can be adaptively adjusted according to the number B of the braille squares to be printed in each row on the paper 2, so that the number A of the printing modules 5 arranged on the moving mechanism is equal to the number B of the braille squares printed in each row on the paper 2. Only by setting the distance between two adjacent printing modules 5 to be 1 times the distance between two adjacent braille squares, the braille squares in each row on the paper 2 can be printed at one time, improving the printing speed of the braille dot printer, and the multiple of the printing speed increase is B times. If the number A of the printing modules 5 to be used is less than the number B of the braille squares printed in each row on the paper 2, and the number B of the braille squares printed in each row on the paper 2 is a positive integer multiple C of the set number A of the printing modules 5, only by setting the distance between two adjacent printing modules 5 to be 1 times the distance between two adjacent braille squares, the braille squares in each row on the paper 2 can be printed C times, improving the printing speed of the braille dot printer, and the multiple of the printing speed increase is B times.If the number A of the engraving modules 5 is less than the number B of the Braille squares engraved in each row on the paper 2, the number B of the Braille squares engraved in each row on the paper 2 is a non-positive integer multiple of the set number A of the engraving modules 5, and the quotient of the number B of the Braille squares engraved in each row on the paper 2 divided by the number A of the engraving modules 5 on the moving mechanism is D. That is to say, in the case where the number B of the Braille squares engraved in each row on the paper 2 cannot be divided evenly by the number A of the engraving modules 5 on the moving mechanism, each row of Braille squares on the paper 2 can also be engraved D + 1 times, improving the engraving speed of the Braille engraving machine, and the multiple E of the increased engraving speed is 1 < E < B. That is to say, the number A of the engraving modules 5 to be used can be adaptively adjusted according to the number B of the Braille squares to be engraved in each row on the paper 2, so that the number A of the engraving modules 5 set on the moving mechanism is less than or equal to the number B of the Braille squares engraved in each row on the paper 2, and the distance between two adjacent engraving modules 5 is a positive integer multiple of the distance between two adjacent Braille squares. In this way, since the number of the engraving modules 5 set on the moving mechanism is at least two, and the number A of the engraving modules 5 set on the moving mechanism is less than or equal to the number B of the Braille squares engraved in each row on the paper 2, and the distance between two adjacent engraving modules 5 is a positive integer multiple of the distance between two adjacent Braille squares. In this way, when engraving Braille dots by the Braille dot engraving machine, at least two Braille squares in each row on the paper 2 can be engraved simultaneously, effectively improving the engraving speed of the Braille engraving machine and overcoming the problem of slow engraving speed of the Braille squares.

[0044] In some embodiments, at least two engraving modules 5 are arranged side by side on the moving mechanism. The number B of the Braille squares engraved in each row on the paper 2 is 1 to 20 times the set number of the engraving modules 5. The distance between two adjacent engraving modules 5 is 1 to 3 times the distance between two adjacent Braille squares. 2 to 5 engraving modules 5 are arranged side by side on the moving mechanism, and the distances between two adjacent engraving modules 5 are equal. It is possible to more conveniently and quickly flexibly adjust the engraving method according to the actual arrangement form of the Braille squares on the paper 2, engrave 2 to 5 Braille squares in each row on the paper 2 simultaneously, and improve the engraving speed of the Braille engraving machine.

[0045] Please refer to Figure 3 、 Figure 4 and Figure 5, in some of these embodiments, the first moving module 3 includes two roller guide mechanisms arranged in pairs. Each roller guide mechanism includes a roller bracket 31, a first guide rail 32, a first motor 33, a first synchronous pulley 34, a first toothed belt 35, and four first bearing rollers 36. The first guide rail 32 is disposed on the carrier table 1. Two first bearing rollers 36 are respectively provided on the upper and lower sides of the first guide rail 32. The rolling surfaces of the first bearing rollers 36 are in rolling contact with the first guide grooves 321 on the corresponding side surfaces of the first guide rail 32. The first motor 33 is disposed on the roller bracket 31. The first synchronous pulley 34 is connected to the output shaft of the first motor 33. The toothed portion of the first toothed belt 35 meshes with the toothed portion on the first synchronous pulley 34. By driving the first synchronous pulley 34 to rotate through the first motor 33, since the roller bracket 31 is supported on the first guide rail 32 by rolling through the four first bearing rollers 36, the roller bracket 31 can move along the Y-axis direction, realizing driving the engraving head 51 to move along the Y-axis direction. At the same time, the second moving module 4 for driving the engraving head 51 to move along the X-axis direction is respectively connected to the roller brackets 31 of the two roller guide mechanisms. At least two driving mechanisms 52 arranged side by side are connected to the second moving module 4, and an engraving head 51 is installed on each driving mechanism 52. Then, multiple engraving heads 51 can be synchronized to perform two-dimensional movement on a two-dimensional plane parallel to the paper 2, and the corresponding engraving heads 51 can be controlled by the respective driving mechanisms 52 to engrave Braille bumps and the action of retracting after engraving is completed, realizing engraving uniform and complete Braille dots on the paper 2.

[0046] Please refer to Figure 2 and Figure 3 , in some of these embodiments, the first toothed belt 35 is a linear synchronous belt. The two ends of the first toothed belt 35 are respectively fixed to the first guide rail 32. A first synchronous pulley 34 is disposed between the two first bearing rollers 36 on the same side of the first guide rail 32. The two first bearing rollers 36 on the same side of the first guide rail 32 press the first toothed belt 35 into the first guide groove 321, so that the first motor 33 is in transmission connection with the first bearing rollers 36. In this embodiment, when the first motor 33 drives the first synchronous pulley 34 to rotate, since the two ends of the first toothed belt 35 are respectively fixed to the first guide rail 32, the first motor 33 and the roller bracket 31 are driven to move through the reaction force of the first synchronous pulley 34. Coupled with the fact that the roller bracket 31 is supported on the first guide rail 32 by rolling through the four first bearing rollers 36, and the first toothed belt 35 is pressed into the first guide groove 321 by the two first bearing rollers 36 on the same side of the first guide rail 32, the roller bracket 31 can be realized to stably drive the engraving head 51 to perform high-precision movement, and can ensure the smoothness of the high-speed operation of the roller bracket 31, as well as reduce the noise generated during the high-speed operation of the roller bracket 31.

[0047] Please refer to Figure 2 and Figure 3, in some embodiments, the roller guide mechanism further includes four first roller shafts 37 for rotatably mounting the four first pressure-bearing rollers 36 on the roller bracket 31 respectively, a first limit sleeve 38 sleeved on each first roller shaft 37, and a locking sleeve 39 sleeved on the first roller shaft 37. Each first pressure-bearing roller 36 is clamped between the corresponding first limit sleeve 38 and the corresponding locking sleeve 39. Through the above structural arrangement, it is possible to prevent the first pressure-bearing roller 36 from tilting and yawing during rolling, which affects the smooth operation of the roller bracket 31 at high speed.

[0048] Please refer to Figure 2 and Figure 3 , in some embodiments, the first guide groove 321 is a trapezoidal groove in cross section, and a trapezoidal protrusion 361 matching the first guide groove 321 is provided on the rolling surface of the first pressure-bearing roller 36. The trapezoidal protrusion 361 is in rolling contact with the trapezoidal groove, which can further prevent the first pressure-bearing roller 36 from tilting and yawing during rolling, which affects the smooth operation of the roller bracket 31 at high speed.

[0049] Please refer to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the second moving module 4 includes a slide 41, a second guide rail 42, a second motor 43, a second synchronous pulley 44, a second toothed belt 45, and four second pressure-bearing rollers 46. Two second pressure-bearing rollers 46 are respectively provided on both sides of the second guide rail 42. The rolling surface of each second pressure-bearing roller 46 is in rolling contact with a second guide groove 421 on the corresponding side surface of the second guide rail 42. The second motor 43 is arranged on the slide 41. The second synchronous pulley 44 is connected to the output shaft of the second motor 43. The toothed part of the second toothed belt 45 is engaged with the toothed part on the second synchronous pulley 44. By driving the second synchronous pulley 44 to rotate through the second motor 43, since the slide 41 is supported on the second guide rail 42 by four second pressure-bearing rollers 46 in a rolling manner, the slide 41 can move along the X-axis direction, realizing driving the printing head 51 to move along the X-axis direction. At the same time, both ends of the second guide rail 42 are respectively connected to the roller brackets 31 of the two roller guide mechanisms. At least two driving mechanisms 52 are connected to the slide 41 of the second moving module 4, and a printing head 51 is installed on each driving mechanism 52. Then, at least two printing heads 51 can perform two-dimensional movement on a two-dimensional plane parallel to the paper 2, and the corresponding printing heads 51 can be controlled by each driving mechanism 52 to print Braille bumps and retract after printing is completed, realizing printing uniform and complete dot-matrix Braille dots on the paper 2.

[0050] Please refer to Figure 6 , Figure 7 and Figure 8, in some embodiments, the second toothed belt 45 is a straight synchronous belt. Both ends of the second toothed belt 45 are respectively fixed on the second guide rail 42. A second synchronous pulley 44 is arranged between two second pressure-bearing rollers 46 on the same side of the second guide rail 42. The two second pressure-bearing rollers 46 on the same side of the second guide rail 42 press the second toothed belt 45 against the second guide groove 421, so that the second motor 43 is in transmission connection with the second pressure-bearing rollers 46. In this embodiment, when the second motor 43 drives the second synchronous pulley 44 to rotate, since both ends of the second toothed belt 45 are respectively fixed on the second guide rail 42, the second motor 43 and the slide table 41 are driven to move by the reaction force of the second synchronous pulley 44. Coupled with the fact that the slide table 41 is supported on the second guide rail 42 by rolling through four second pressure-bearing rollers 46, and the two second pressure-bearing rollers 46 on the same side of the second guide rail 42 press the second toothed belt 45 against the second guide groove 421, it is possible to achieve the slide table 41 stably driving at least two engraving heads 51 to move synchronously with high precision, and to ensure the smoothness of the high-speed operation of the slide table 41, as well as to reduce the noise generated during the high-speed operation of the slide table 41.

[0051] Please refer to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the second moving module 4 further includes four second roller shafts for rotatably mounting the four second pressure-bearing rollers 46 on the slide table 41 respectively, and two second limit sleeves sleeved on each second roller shaft. Each second pressure-bearing roller 46 is clamped between the corresponding two second limit sleeves. Through the above structural arrangement, it is possible to prevent the second pressure-bearing rollers 46 from tilting and yawing during the rolling process, which may affect the smoothness of the high-speed operation of the slide table 41.

[0052] Please refer to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the second moving module 4 further includes a limiting plate for limiting the four second roller shafts. The first end of each second roller shaft is connected to the slide table 41, and the second end of each second roller shaft is connected to the limiting plate. Through the above structural arrangement, it is possible to limit the installation positions of the four second pressure-bearing rollers 46, and to avoid the four second pressure-bearing rollers 46 from tilting and yawing during the stress process, which may affect the smoothness of the high-speed operation of the slide table 41.

[0053] Please refer to Figure 1 and Figure 3 , in some embodiments, a mounting plate 53 is detachably arranged on the slide table 41 through fixing members such as bolts. At least two driving mechanisms 52 are arranged side by side on the mounting plate 53. The driving mechanisms 52 with different numbers and spacings can be disassembled and replaced, which is convenient for flexibly adjusting the engraving method according to the actual arrangement form of the braille squares on the paper 2.

[0054] Please refer to Figure 9 , Figure 10 and Figure 11 . In some embodiments, the driving mechanism 52 is an electromagnetic driving module. The electromagnetic driving module includes a fixed seat 521 fixedly connected to the slide 41 of the second moving module 4, a moving magnet 522 for driving the engraving head 51 to move along the Z-axis direction, an electromagnet 523 for interacting with the moving magnet 522 to drive the moving magnet 522 to move along the Z-axis direction and downward, and an elastic member 524 for driving the moving magnet 522 to move along the Z-axis direction and upward to reset. The electromagnet 523 is fixedly arranged on the fixed seat 521, and the moving magnet 522 is slidably arranged on the fixed seat 521 along the Z-axis direction. When in use, only need to control the electromagnet 523 to be energized through the controller. The magnetic field generated by the electromagnet 523 interacts with the moving magnet 522 to drive the moving magnet 522 to move along the Z-axis direction and downward, so as to control the engraving head 51 to complete the action of engraving Braille bumps on the paper 2 through the electromagnetic driving module. Then, control the electromagnet 523 to be powered off through the controller, and the elastic member 524 drives the moving magnet 522 to move along the Z-axis direction and upward to reset, so as to control the engraving head 51 to complete the rapid retraction action after engraving through the electromagnetic driving module. Repeat the above process to realize engraving a uniform and complete dot matrix Braille dot pattern on the paper 2.

The moving magnet 522 is provided with a stop portion 525 for cooperating with the stop fixed seat 521 to limit the upward movement and reset position of the moving magnet 522, which enhances the stability of the upward movement and reset of the moving magnet 522 and is beneficial for the electromagnetic driving module to realize high-frequency driving of the engraving head 51 for rapid engraving. Specifically, the stop portion 525 is a convex ring structure extending radially outward from the bottom end of the moving magnet 522, and the outer diameter of the convex ring structure is greater than the diameter of the second limiting hole.

[0056] Please refer to Figure 9 and Figure 11 . In some embodiments, the elastic member 524 is a spring. The spring is sleeved on the moving magnet 522. The first end of the spring abuts against the fixed seat 21, and the second end of the spring abuts against the abutting portion 526 at the top end of the moving magnet 522, which can enhance the stability of the elastic member 524 driving the moving magnet 522 to move along the Z-axis direction and upward to reset.

[0057] Please refer to Figure 9 and Figure 10, in some of these embodiments, an accommodation cavity 5211 is provided inside the fixed seat 521, the electromagnet 523 is disposed in the accommodation cavity 5211, the electromagnet 523 has a cylindrical structure, the moving magnet 522 has a columnar structure extending along the Z-axis direction, the moving magnet 522 has a columnar structure extending along the Z-axis direction, the electromagnet 523 is sleeved outside the moving magnet 522, the fixed seat 521 is provided with a first limiting hole and a second limiting hole communicating with the accommodation cavity 5211, the first limiting hole and the second limiting hole are arranged vertically corresponding to each other along the Z-axis direction, and the moving magnet 522 is slidably inserted into the first limiting hole and the second limiting hole. In this embodiment, the up-and-down sliding direction of the moving magnet 522 is limited by the first limiting hole and the second limiting hole, so that the moving magnet 522 can accurately and stably drive the engraving head 51 to reciprocate along the Z-axis direction.

[0058] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
