Description

Technical Field

[0001] The present application relates to the technical field of engraving machines, and in particular to an engraving machine core module and a Braille engraving machine. Background Art

[0002] Braille is a symbol composed of raised dots, also known as "braille", and is the main written communication tool for the visually impaired. The current Braille is expressed using the Braille symbol composed of 6 dots created by the Frenchman Braille in 1825. The basic unit of Braille is "square". A square of Braille is generally composed of six dots in three rows and two columns. Each dot has two different states: "raised" and "non-raised". There are 64 different combinations of the raised states of the six dots. A square of Braille or several squares of Braille can represent information such as letters, syllables, numbers, punctuation marks, etc.

[0003] Braille graphics are graphics composed of raised dots. Unlike Braille characters, Braille graphics are generally composed of individual dots, and each dot may have multiple raised states. In addition to the "non-raised" state, there may be different degrees of "raised". Dots of different densities and raised degrees can represent dot patterns such as lines and surfaces of different textures and shapes. With the development of information technology, there is also a method of printing graphics by directly spraying ink on paper.

[0004] Both Braille and Braille graphics are composed of raised dots, which are generally hemispherical or parabolic in shape, with a bottom diameter of 1 to 1.6 mm and a height of 0.2 to 0.5 mm. Visually impaired people can perceive text and graphics through touch.

[0005] Traditional Braille printed books can basically be divided into two categories: one is solid Braille, and the other is hollow Braille. Solid Braille is also known as solid dot Braille or hard dot Braille. Because it uses PVC, foaming ink, UV ink and other printing materials to print on paper, PVC film or metal, it is small semicircular solid dots. According to its characteristics, it is uniformly named solid dot Braille. Braille printed with solid Braille is durable, not easy to be damaged or deformed, wear-resistant, soft in texture, and does not hurt fingers when read for a long time. It gets rid of the limitation of a single "dot" as the basic unit, and can print the printing ink on the material in a whole piece, which is convenient for printing large-area graphics. Printed products are often well-made, and the cost is generally higher.

[0006] Hollow Braille printing does not require ink, which is what we often call mold embossing. It is the earliest Braille printing method. Hollow Braille uses a printing press or engraving machine to deform the surface of paper with high hardness and strength by mechanical rolling and impact, thereby forming raised or sunken Braille dots. The raised blind spots of Braille books and publications printed by this method are easily flattened by pressure, but in some special occasions, such as tourist instructions in tourist attractions and Braille signs in public places, Braille characters are pressed out on metal iron sheets and are durable. Hollow Braille printing simply uses the printing principle of mechanical impact, which is easier to implement, relatively low cost, and convenient for machine maintenance and promotion. The main driving methods of its mechanical impact are: pneumatic drive, electromagnetic drive, mechanical spring drive and piezoelectric drive.

[0007] Generally, professional braille publishing organizations mass-produce braille printed materials, mostly using large hollow braille engraving machines, which can not only achieve double-sided engraving and fast engraving speed, but also have the characteristics of large size, high noise, low stability and high price. The computer of the braille engraving machine can directly convert the Chinese layout into the braille layout with the help of software, and realize automatic proofreading. Then, the braille is directly output on the paper through the externally connected braille engraving machine.

[0008] At present, Braille engraving machines still rely on mechanical impact methods to produce hollow Braille, and the main driving methods of mechanical impact are: pneumatic drive, electromagnetic drive, mechanical spring drive and piezoelectric drive.

[0009] The disadvantage of the above existing Braille engraving machine is that the page margin adjustment is not precise enough. Summary of the invention

[0057] Example

[0058] Please refer to Figure 1 and Figure 2 An embodiment of the present application provides a Braille engraving machine 2000, including a base frame 600, a control system and an engraving machine movement module, wherein a movement bracket 1000 of the engraving machine movement module is arranged on the base frame 600, and the control system can control the operation of the engraving machine movement module.

[0059] Among them, the control system of this embodiment adopts the control circuit mainboard 700. In addition, the braille engraving machine 2000 also includes a touch screen 200, a housing 100, an auxiliary engraving mechanism 500, and a paper feeding mechanism 800. The touch screen 200, the signal transmission interface 300, the auxiliary engraving mechanism 500, the paper feeding mechanism 800, and the engraving machine movement module are all electrically connected to the control circuit mainboard 700. The control circuit mainboard 700 can power the touch screen 200 and the first stepper motor 404, the second stepper motor 802, the photoelectric switch 507, and the gate-shaped electromagnet 9062 mentioned later. In addition, the servo motor 501 mentioned later can be powered by a power supply alone, or it can be powered by the control circuit mainboard 700. The control circuit mainboard 700 receives data sent by the PC through the wired signal transmission interface 302 and processes it through the STM32 single-chip microcomputer. The control circuit mainboard 700 exchanges data with the touch screen 200 to realize display and parameter control. The control circuit main board 700 controls the engraving by controlling the rotation of the servo motor 501 , controlling the on and off of the gate-shaped electromagnet 9062 , and collecting signals from the photoelectric switch 507 .

[0060] Regarding the touch screen 200 , in this embodiment, the touch screen 200 uses a 7-inch LCD color touch display screen. The touch screen 200 is electrically connected to the control circuit mainboard 700 .

[0061] During operation, the user operates the Braille engraving machine 2000 through the touch screen 200, including the forward and backward movement of the Braille paper (paper feeding and paper retracting), the start and stop of the servo motor 501 described below, the switching between the graphic mode and the Braille mode, the switching between the single-sided mode and the double-sided mode, the selection of engraving parameters such as the number of page lines, page margins, line squares, engraving speed, the start, pause and stop of engraving, etc. The user can also monitor the current engraving working status through the touch screen 200.

[0062] Regarding the engraving machine movement module, please refer to Figures 3 to 9 Among them, the engraving machine movement module includes: an engraving movement 900, a movement bracket 1000 and a horizontal moving mechanism 400.

[0063] For details, please combine Figure 4 As shown, the transverse moving mechanism 400 is arranged on the movement bracket 1000, and the transverse moving mechanism 400 includes a first driving member 410, a transmission assembly 420 and a connecting member 430, and the connecting member 430 is connected to the output end of the first driving member 410 through the transmission assembly 420. The engraving movement 900 includes a mounting frame 910 and an engraving mechanism 920, and the engraving mechanism 920 is arranged on the mounting frame 910, and the connecting member 430 is connected to the mounting frame 910, and the mounting frame 910 is movably arranged on the movement bracket 1000;

[0064] The paper feeding direction of the core module of the engraving machine is the preset direction 3000, and the first driving member 410 can drive the connecting member 430 to move the mounting frame 910 in a horizontal direction perpendicular to the preset direction.

[0065] Simply put, the transverse moving mechanism 400 can drive the connecting member 430 through the first driving member 410, thereby driving the mounting frame 910 to move, and finally realizing the transverse movement of the engraving mechanism 920 relative to the movement bracket 1000, which can expand the adjustment range of the page margins and make the page margin adjustment during engraving more precise.

[0066] In detail, the transmission assembly 420 includes a base 403, a lead screw 401, and a nut 402. The lead screw 401 is rotatably disposed on the base 403, the nut 402 cooperates with the lead screw 401, the first driving member 410 is a rotating driving member, one end of the lead screw 401 is connected to the output end of the rotating driving member, and the connecting member 430 is connected to the nut 402. Through the cooperation of the lead screw 401 and the nut 402, the movement of the connecting member 430 can be made more precise, and the fine adjustment of the engraving mechanism 920 is realized. Finally, the adjustment of the page margin is also made more precise.

[0067] Please combine Fig. 9 In this embodiment, a first stepper motor 404 is used as the first driving member 410, a ball screw is used as the screw 401, and a ball screw nut is used as the nut 402. In this embodiment, the mounting frame 910 includes a movement optical axis 902, and the connecting member 430 includes a bayonet 405, and the movement optical axis 902 is clamped into the bayonet 405. Clamping the movement optical axis 902 through the bayonet 405 is convenient for installation and can normally drive the movement optical axis 902 to move, and the design is simple and practical. During operation, the control circuit main board 700 sends a control signal to the first stepper motor 404, which can control the rotation of the first stepper motor 404, and the rotation direction and rotation angle are controlled by the control circuit main board 700; the first stepper motor 404 drives the ball screw to rotate, so that the ball screw nut moves horizontally, and the movement direction is related to the rotation direction of the ball screw; the ball screw nut drives the engraving movement 900 to move horizontally through the bayonet 405, so that the engraving movement 900 and the movement bracket 1000 produce a horizontal and horizontal relative displacement.

[0068] It should be noted that the first stepper motor 404 here and the second stepper motor 802 of the paper feeding mechanism 800 described below are both existing stepper motors, which are only described separately here without limiting their priority or importance.

[0069] Alternatively, a gear rack mechanism can be used as the transmission assembly 420. For example, the gear can be connected to the output shaft of the motor, the position of the motor is fixed, and the rack can be slidably arranged on the movement bracket 1000. A seat can also be arranged so that the rack can slide and mesh with the gear. The connecting member 430 is installed on the other side opposite to the tooth surface of the rack, and then the bayonet 405 of the connecting member 430 also clamps the optical axis.

[0070] When the motor is working, the rack slides and drives the connecting member 430 to move, and finally drives the optical axis to move. Then the mounting frame 910 can be moved. By arranging the racks horizontally, the mounting frame 910 can be driven horizontally, so that the engraving mechanism 920 can be displaced horizontally. Since the meshing of the gear rack is stable and has good adjustment accuracy, the adjustment accuracy and stability can be guaranteed when adjusting the page margins.

[0071] Please combine Figure 6 The engraving mechanism 920 includes a striker baffle 904 and a striker mechanism 906. The mounting frame 910 also includes a movement support plate 901. The movement optical axis 902 is disposed on the movement support plate 901. The striker mechanism 906 is disposed on the movement support plate 901. The striker baffle 904 is slidably disposed on the movement optical axis 902 through an optical axis bearing 903 and is used to cooperate with the striker mechanism 906 for engraving. The striker baffle 904 is fixed on the optical axis bearing 903, and the optical axis bearing 903 is sleeved on the movement optical axis 902.

[0072] The movement optical axis 902 can guide the striker baffle 904, and the movement optical axis 902 is connected to the movement support plate 901 and maintains a relative position, so that the striker baffle 904 and the striker mechanism 906 do not deviate when they cooperate in engraving, thereby ensuring the quality of engraving. A compression spring 905 is also provided between the striker baffle 904 and the movement support plate 901, and the compression spring 905 is sleeved on the movement optical axis 902. When not engraved, a spacing is maintained between the striker baffle 904 and the striker mechanism 906 to facilitate the passage of Braille paper. In addition, the compression spring 905 can also assist the striker baffle 904 in resetting, so that the striker baffle 904 can be reset downward under the action of its own gravity and the compression spring 905 when there is no cam bearing 505 (proposed below) to resist. Of course, the compression spring 905 can also reduce the impact force between the striker baffle 904 and the movement support plate 901 caused by the reciprocating motion of the striker baffle 904.

[0073] Please combine Figure 7 and Figure 8In detail, the striker baffle 904 is provided with a first convex striker 9042 and a concave pit 9041, and the striker mechanism 906 includes a second convex striker 9066 and a concave striker 9067. The first convex striker 9042 matches the concave striker 9067, and the second convex striker 9066 matches the concave pit 9041. At the top of the striker baffle 904, there are 82 concave pits 9041, which are arranged in a row at equal intervals; 82 first convex strikers 9042 are embedded in the striker baffle 904 and arranged in two rows, and the heads of the first convex strikers 9042 are exposed outside the striker baffle 904, and are vertically aligned with the concave striker 9067, and can be engaged with it.

[0074] Please combine Figure 8 In detail, the striker mechanism 906 further includes a second driving member 916 and a transmission structure 926. Each second convex striker 9066 or concave striker 9067 is driven individually by the corresponding second driving member 916 through the transmission structure 926. By driving the second convex striker 9066 or concave striker 9067 respectively, the corresponding second convex striker 9066 or concave striker 9067 can be accurately driven according to the braille to be engraved, thereby ensuring the quality of engraving.

[0075] Please continue to combine Figure 8 In more detail, the second driving member 916 of this embodiment adopts a gate-shaped electromagnet 9062, which is matched with an electromagnet circuit board 9061. The transmission structure 926 is a lever structure, which includes a lever fixing seat 9068 and a primary lever 9063 and a secondary lever 9065 arranged on the lever fixing seat 9068. A reset member is also arranged between the secondary lever 9065 and the lever fixing seat 9068, such as the sponge bar 9064 in this embodiment. Of course, common reset parts such as shrapnel and spring can also be selected as reset members. The above parts can be divided into four groups, each group including an electromagnet circuit board 9061, 42 gate-shaped electromagnets 9062, 42 primary levers 9063, 1 sponge bar 9064, 42 secondary levers 9065, 42 second convex strikers 9066 or concave strikers 9067, and two lever fixing seats 9068. Among them, the electromagnet circuit board 9061 is used to fix the gate-shaped electromagnet 9062, and is electrically connected to the gate-shaped electromagnet 9062 and the control circuit main board 700; the gate-shaped electromagnet 9062 is used to attract the primary lever 9063; the primary lever 9063 and the secondary lever 9065 form a transmission structure 926, one end of the two are in contact with each other, the central axis of the lever is clamped on the lever fixing seat 9068, and can rotate around the central axis; the second convex head striker 9066 and the concave head striker 9067 are respectively connected to their corresponding secondary levers 9065; the lever fixing seat 9068 is fixed on the movement support plate 901.

[0076] The first convex striker 9042 matches the concave striker 9067, and the second convex striker 9066 matches the concave pit 9041, providing a structural basis for double-sided Braille engraving. When the gate-shaped electromagnet 9062 pushes the second convex striker 9066 or the concave striker 9067 through the lever structure, the position of the striker baffle 904 remains unchanged, and as long as the pushing distance is strong enough, the engraving work on the engraving paper can be achieved.

[0077] Please combine Fig.10 In order to better complete the engraving work, in this embodiment, the Braille engraving machine 2000 is provided with an auxiliary engraving mechanism 500, the auxiliary engraving mechanism 500 includes a driving device and a cam mechanism, the movement bracket 1000 includes a slide rail, and the movement support plate 901 can be slidably arranged on the slide rail.

[0078] For details, please contact Figure 5 The slide rails are divided into fixed slide rails 1002 and movable slide rails 1003. The engraving mechanism 900 can be slidably arranged on the fixed slide rails 1002 and the movable slide rails 1003. The driving device drives the movable slide rails 1003 to reciprocate through the cam mechanism. By designing the auxiliary engraving mechanism 500, a certain power basis can be provided for double-sided printing of Braille.

[0079] Among them, the slide rail provides auxiliary guidance for the movement of the movement support plate 901, making the movement of the movement support plate 901 more stable, and on the other hand, it is also conducive to the lateral movement of the movement support plate 901, avoiding the movement support plate 901 directly moving on other mechanisms and causing movement blockage and unnecessary wear of the mechanism. In this embodiment, the top of the movement support plate 901 slides with the fixed slide rail 1002 through the upper slider 1004, and the striker top plate slides with the movable slide rail 1003 through the lower slider 1004. Optionally, rollers can also be set on the slide rail or the slider 1004 to reduce the friction between the slide rail and the slider 1004.

[0080] The driving device used in this embodiment is a servo motor 501, and the cam mechanism includes a main shaft 502 and a support bearing 504 and a cam bearing 505 sleeved on the main shaft 502. There are two support bearings 504 in this embodiment, both of which are connected to the bottom of the support frame 1001 of the movement support 1000; there are two cam bearings 505, with the same protrusion direction, which correspond to the driven shaft 1005 below the movable slide rail 1003. The driven shaft 1005 is slidably arranged in the movement support 1000 through a sliding bearing 1006, one end of which is connected to the movable slide rail 1003, and the other end is used to be pushed by the cam bearing 505, and the sliding bearing 1006 is fixed to the support frame 1001. The servo motor 501 is fixed on the bottom plate 603 of the base frame 600 and is electrically connected to the control circuit main board 700. It is connected to the main shaft 502 through the transmission mechanism 503. When the servo motor 501 is working, the cam bearing 505 can rotate and push the driven shaft 1005 under the drive of the main shaft 502, and finally make the striker baffle 904 on the movable slide rail 1003 move upward, so that the first convex striker 9042 cooperates with the concave striker 9067 and / or the second convex striker 9066 cooperates with the concave pit 9041 to complete the engraving operation.

[0081] In detail, the transmission mechanism 503 used in this embodiment is a synchronous wheel mechanism, which is composed of two synchronous wheels and a transmission belt. The large transmission wheel is sleeved on the main shaft 502, and the small transmission wheel is sleeved on the output shaft of the servo motor 501.

[0082] The auxiliary engraving mechanism 500 also includes a printing positioning plate 506, which is installed on the side of the main shaft 502 away from the synchronous wheel mechanism and is a circular metal plate with a notch. A photoelectric switch 507 is correspondingly arranged on the movement bracket 1000 and is electrically connected to the control circuit main board 700. The number of rotations of the main shaft 502 can be determined through the notch on the printing positioning plate 506, thereby determining the number of rotations of the cam bearing 505.

[0083] During operation, the control circuit main board 700 sends a control signal to the servo motor 501, which can control the rotation of the servo motor 501. The rotation speed and rotation time are controlled by the control circuit main board 700. The servo motor 501 drives the main shaft 502 to rotate through the transmission mechanism 503, thereby driving the cam bearing 505 and the print positioning plate 506 to rotate. The cam bearing 505 drives the driven shaft 1005 to reciprocate up and down. When the photoelectric switch 507 detects the notch on the print positioning plate 506, it returns a signal to the control circuit main board 700.

[0084] In the power-off state, there is a gap between the striker baffle 904 and the striker of the striker mechanism 906, and the engraving paper can pass through. After power is turned on, the control circuit main board 700 can control the on and off of each gate-shaped electromagnet 9062. When the electromagnet is turned on, it will attract the primary lever 9063, causing it to rotate a small angle, and drive the secondary lever 9065 to rotate a small angle, and finally move the second convex striker 9066 or the concave striker 9067 downward by 3mm (it can be understood that when there are different engraving requirements, the downward movement distance here can be different). When the electromagnet is powered off, the sponge strip 9064 will give a squeezing force to the secondary lever 9065, causing the second convex striker 9066 or the concave striker 9067 to return to its original position.

[0085] As mentioned above, when the servo motor 501 rotates, the cam bearing 505 drives the driven shaft 1005 to reciprocate up and down, thereby driving the striker baffle 904 to reciprocate up and down. When the striker baffle 904 moves up to a certain distance, the concave pit 9041 engages with the second convex striker 9066 that moves down, and squeezes out a concave point at the corresponding position on the paper, that is, the reverse point when both sides are engraved; the first convex striker 9042 engages with the concave striker 9067 that moves down, and squeezes out a convex point at the corresponding position on the paper, that is, the front point when both sides are engraved. The striker baffle 904 will not engage with the return striker, and there will be no change in the corresponding position on the paper.

[0086] It is understandable that, in addition to the above-mentioned cam mechanism in combination with the motor, commonly used reciprocating motion mechanisms such as crank rocker mechanisms can also be selected, as long as the output ends of these mechanisms can be transmitted to the driven shaft 1005 so that the driven shaft 1005 can achieve up and down movement.

[0087] Regarding the paper feeding mechanism 800, please refer to Fig.11 In this embodiment, the paper feeding mechanism 800 is arranged on the core support 1000 of the imprinting machine core module, and the paper feeding mechanism 800 is used to deliver or withdraw paper to the imprinting core 900. The paper feeding mechanism 800 can realize paper feeding and paper withdrawal, facilitate the adjustment of the imprinting area, and also facilitate the adjustment of the line spacing.

[0088] In detail, the paper feeding mechanism 800 includes a paper feeder bracket 801, a second stepper motor 802, a paper feeder 803, a paper feeder transmission system 804, and a first paper support board 805. Among them, the paper feeder bracket 801 is fixed on the movement bracket 1000, and is used to support other parts of the paper feeding system; the second stepper motor 802 is electrically connected to the control circuit main board 700, and the second stepper motor 802 body is fixed on the paper feeder bracket 801; the paper feeder 803 is composed of two synchronously rotating shafts and a paper presser, etc., and is fixed on the paper feeder bracket 801 through a bearing. The function of the paper feeder 803 is to fix the paper and drive the paper to move horizontally forward and backward; the paper feeder transmission system 804 is composed of two synchronous wheels and a transmission belt, one of which is sleeved on the rotor of the second stepper motor 802, and the other synchronous wheel is sleeved on an axis of the paper feeder 803; the first paper support board 805 is used to support a special perforated Braille information paper. Corresponding to the first paper support board 805 , a second paper support board 1007 is fixed on the movement bracket 1000 , and its height is consistent with that of the first paper support board 805 .

[0089] When working, the control circuit main board 700 sends a control signal to the second stepper motor 802, which can control the second stepper motor 802 to rotate, and the rotation direction and rotation angle are controlled by the control circuit main board 700; the second stepper motor 802 drives the axis of the paper feeder 803 to rotate through the paper feeder transmission system 804, and the paper feeder 803 drives the paper to move horizontally forward and backward. The paper feeding mechanism 800 can refer to the functional structure of a general paper feeding mechanism, which will not be repeated here.

[0090] Regarding the base frame 600, please refer to Fig.12 The base frame 600 of this embodiment includes an outer frame 601 and a column 602. The outer frame 601 is covered with a housing 100, and the column 602 is a core support 1000 for placing the core module of the marking machine. A bottom plate 603 is also provided under the base frame 600, which can be used to support other mechanisms, such as the auxiliary marking mechanism 500.

[0091] Please combine Fig.13 In this embodiment, the housing 100 includes a front side panel 101, a right side panel 106, a rear side panel 107, an upper side panel 108 and a left side panel 109, wherein the front side panel 101 is provided with a paper feed hole 102, a touch screen hole 103 and a signal transmission hole 104; the rear side panel 107 is provided with a paper output hole 110. The paper feed hole 102 is used to insert Braille paper, and the paper output hole 110 is used to output the engraved paper, and the two holes are on the same horizontal plane as the paper feeding mechanism 800. The touch screen hole 103 is used to support the touch screen 200, and the signal transmission hole 104 is used to support the signal transmission interface 300. The signal transmission interface 300 can be referred to Fig.14The signal transmission interface 300 includes a power interface 301, a wired signal transmission interface 302, and a power switch 303. The power interface 301 is used for the electrical connection between the braille engraving machine 2000 and the 220V power supply, adopts a C19 standard socket, and is electrically connected to the control circuit main board 700 internally; the wired signal transmission interface 302 is used for wired data exchange between the braille engraving machine 2000 and the computer, adopts an RS-232 serial communication standard interface and a USB communication interface, and is electrically connected to the control circuit main board 700 internally; the power switch 303 uses an automatic air switch, which is electrically connected to the power interface 301 and the control circuit main board 700, and is used to control the on and off of the electrical connection between the power interface 301 and the control circuit main board 700. The user can manually open and close it. When the circuit of the braille engraving machine 2000 is overloaded, it will automatically close to protect the internal equipment.

[0092] In short, by using the engraving machine movement module, the control system can control the engraving movement 900 to work, and control the lateral movement mechanism 400 to drive the engraving movement 900 to adjust its position according to the page margin requirements, effectively solving the problem that the existing engraving machine is not fine enough for adjusting the page margin. At the same time, since the lateral position of the engraving movement 900 can be adjusted, the braille engraving machine 2000 can also make the engraved graphics have a higher resolution when engraving graphics, and the position of the braille dots can also be finely adjusted.

[0093] The following is an operating example of the embodiment of the present application:

[0094] 1. Common operations of the Braille Marker 2000 by users.

[0095] (1) Preparation for engraving:

[0096] This operation needs to be completed manually by the user.

[0097] Before using the braille engraving machine 2000, first check that all parts of the braille engraving machine 2000 are intact, the housing 100 is intact, and the power switch 303 is in the off state;

[0098] Plug the power cord into the power interface 301 and then connect it to the 220V mains;

[0099] After there is no abnormality, insert the continuous perforated Braille information paper from the paper feed hole 102 and fix the paper with the paper feeder 803;

[0100] Use a USB cable or RS-232 serial cable to connect the wired signal transmission interface 302 to the computer;

[0101] Turn on the power switch 303, and when completed, the touch screen 200 will be illuminated;

[0102] (2) Adjust the marking parameters

[0103] This operation needs to be completed manually by the user.

[0104] After the preparation for engraving is completed, before starting the engraving, the engraving parameters need to be adjusted on the touch screen 200. After the parameter adjustment is completed, the touch screen 200 transmits the parameter data to the control circuit mainboard 700. The parameters that need to be adjusted are:

[0105] Graphic mode / Braille mode. In different modes, the user needs to transmit data of different formats to the Braille engraving machine 2000. The control circuit mainboard 700 analyzes the received data differently, and the specific engraving process of the Braille engraving machine 2000 is also different.

[0106] Single-sided mode / double-sided mode. This option is only available in Braille mode. In single-sided mode, only one side of the Braille paper is engraved with Braille, and in double-sided mode, both sides of the Braille paper are engraved with Braille. In the two modes, the format of the data transmitted by the user to the Braille engraving machine 2000 is the same, but the control circuit main board 700 interprets the received data differently, and the specific engraving process of the Braille engraving machine 2000 is also different.

[0107] Page lines, this option is only available in Braille mode, and refers to the maximum number of Braille lines per side of each page. The Braille Imprinter 2000 determines the line spacing, i.e. the distance between two adjacent Braille lines, based on this parameter.

[0108] Page margin refers to the blank width on the left side of the braille paper for easy binding. After receiving the parameter information, the control circuit main board 700 controls the engraving movement 900 and the movement bracket 1000 to produce horizontal and horizontal relative displacement through the lateral movement mechanism 400, thereby realizing the adjustment of the page margin, and the cooperation of the lead screw 401 and the nut 402, or the cooperation of the gear rack, can make the movement accuracy of the engraving movement 900 higher during adjustment. The purpose of the lateral movement mechanism 400 is to facilitate the engraving of graphics to improve the resolution, as well as the fine adjustment of the position of the braille engraving point. In the prior art, 42 square brailles can fill a whole line, and a line of a general book is 30 squares. The blank space in the first few squares can control the page margins, but this adjustment method is not fine enough for adjusting the page margins in actual use. The braille engraving machine 2000 of the present application can steplessly adjust the page margins and the position of the points due to the presence of the lateral movement mechanism 400.

[0109] The number of squares per row is only available in the Braille mode and refers to the maximum number of Braille squares per row. The control circuit main board 700 controls the number of squares per row by controlling the on and off of the gate-shaped electromagnet 9062.

[0110] Marking speed. Refers to the number of lines of dots that the Braille marking machine 2000 can mark per minute. The control circuit main board 700 adjusts the marking speed by controlling the rotation speed of the servo motor 501, which is divided into three levels: high, medium and low.

[0111] (3) Transmitting marking data

[0112] This operation needs to be completed manually by the user.

[0113] The user operates the computer software to send data to the braille engraving machine 2000. In the two different modes of graphics and braille, the software used is different, and the data format sent is also different. After receiving the data, the braille engraving machine 2000 will have a prompt message on the touch screen 200.

[0114] 2. Example of single-sided Braille printing

[0115] A complete single-sided Braille engraving process is as follows:

[0116] A. Complete the "preparation work for engraving";

[0117] B. Adjust the printing parameters, select Braille mode, single-sided mode, 26 lines per page, 50mm margin, 40 lines per page, and medium printing speed;

[0118] C. Transmit the engraving data. After a prompt message appears on the touch screen 200, click "Start Engraving". The servo motor 501 starts and rotates at a constant speed corresponding to the medium speed;

[0119] D. Photoelectric switch 507 detects the position of cam bearing 505. When striker baffle 904 moves down, each gate-shaped electromagnet 9062 is powered on or off according to the instruction of control circuit main board 700, and maintains this state until the next instruction; cam bearing 505 drives striker baffle 904 to move up, and prints the first line of dots of a line of Braille on the paper; striker baffle 904 moves down again, and paper feeder 803 drives the paper to move forward horizontally by 2.6mm, and gate-shaped electromagnet 9062 receives new instructions. Repeat the above process three times, and print a line of Braille on the paper; paper feeder 803 drives the paper to move forward horizontally by a distance determined by the page line number parameter;

[0120] E. Repeat process D to print the next page of Braille on the paper. The paper feeder 803 drives the paper to move forward horizontally for a certain distance and switches to the next page.

[0121] F. Repeat process DE until all data are engraved;

[0122] G. After the imprinting is finished, the user removes the paper.

[0123] The above process is applicable to double-sided and single-sided Braille engraving. When single-sided engraving is performed, the second convex head striker 9066 will not move downward.

[0124] 3. Graphic engraving example

[0125] A complete graphic engraving Braille process is as follows:

[0126] A. Complete the "preparation work for engraving";

[0127] B. Adjust the printing parameters, select the graphic mode, page margin 50mm, and medium printing speed;

[0128] C. Transmit the engraving data. After a prompt message appears on the touch screen 200, click "Start Engraving". The servo motor 501 starts and rotates at a constant speed corresponding to the medium speed;

[0129] D. The photoelectric switch 507 detects the position of the cam bearing 505. When the striker baffle 904 moves down, each gate-shaped electromagnet 9062 is powered on or off according to the command of the control circuit main board 700, and maintains this state until the next command; the cam bearing 505 drives the striker baffle 904 to move up, and prints a part of the first row of dots of the pattern on the paper; the striker baffle 904 moves down again, and the horizontal moving mechanism 400 drives the engraving movement 900 to move 1.5mm to the right, and the gate-shaped electromagnet 9062 receives the new command. Repeat the above process three times, print a row of dots on the paper, and the movement position returns; the paper feeder 803 drives the paper to move forward horizontally by 1.5mm;

[0130] E. Repeat process D to print the next page of graphics on the paper, and the paper feeder 803 drives the paper to move forward horizontally for a distance to switch to the next page;

[0131] F. Repeat process DE until all data are engraved;

[0132] G. After the imprinting is finished, the user removes the paper.

[0133] The above are just some examples of different modes and different engraving processes. It can be understood that the lateral movement mechanism 400 makes the adjustment of the page margin more precise, and can improve the adjustment accuracy of the page margin compared with the prior art. The position of the engraving point can also be adjusted more precisely, which not only improves the engraving quality of Braille, but also improves the engraving resolution of graphics. Users can select the mode and set the parameters according to actual needs, which will not be repeated here.

[0134] In summary, the engraving machine core module of the present application, the engraving machine core 900 can be moved horizontally relative to the core support 1000 by using the horizontal moving mechanism 400. This makes the page margin adjustment sufficiently fine. It also makes the Braille engraving machine 2000 using the engraving machine core module have the following advantages: it is convenient to print pictures and improve the resolution; it is convenient to adjust the page margin more finely; it is convenient to adjust the dot position more finely.

[0135] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
