They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] like Figures 1-2As shown, this embodiment provides a marking and printing machine, including a bed 1, a worktable 4, a movable gantry beam 2, and a printing module 3. The movable gantry beam 2 spans above the worktable 4 and is slidably mounted on the bed 1 via a longitudinal moving mechanism. The printing module 3 is slidably mounted on the movable gantry beam 2 via a transverse moving mechanism. The printing module 3 includes a plurality of printing single modules 12 arranged sequentially along the transverse direction, and adjacent printing single modules 12 are connected by a connecting plate 13. In this embodiment, the printing module 3 is moved laterally on the movable gantry beam 2 via a transverse moving mechanism, and the printing module 3 and the movable gantry beam 2 are moved longitudinally on the bed 1 via a longitudinal moving mechanism. This allows for the marking and printing of characters on a stationary steel plate 25, replacing manual handwriting of part information and drawing of assembly lines on the steel plate, reducing labor costs, improving work efficiency, and avoiding human error. Furthermore, the printing module 3 is composed of multiple printing single modules 12 spliced ​​laterally. The number of printing single modules 12 determines the printing width of the printing module 3 in one pass. The more printing single modules 12 there are, the wider the printing width of the printing module 3 in one pass, and the higher the work efficiency. When a printing single module 12 malfunctions, only the corresponding printing single module 12 needs to be replaced or repaired, without disassembling or replacing the entire printing module 3, which helps to reduce maintenance costs and shorten repair time.

[0030] Furthermore, the printing module 12 includes a printing box 18, a printing box mounting base 16, a printing cabinet 22, and a cabinet mounting base 23. The printing box 18 is mounted on the printing box mounting base 16, and the printing cabinet 22 is mounted on the cabinet mounting base 23. The printing box 18 is connected to the printing cabinet 22, and the printing box mounting base 16 is connected to the cabinet mounting base 23. Adjacent printing box mounting bases 16 are connected by connecting plates 13. In this embodiment, the printing box 18 is electrically connected to the printing cabinet 22. The printing cabinet 22 can control the printing box 18 to scribble and print on the steel plate 25. Adjacent printing box mounting bases 16 are connected by connecting plates 13, thereby connecting and fixing all printing modules 12 into one unit. A lateral movement mechanism can drive all printing modules 12 to move laterally together on the movable gantry beam 2.

[0031] Furthermore, the inkjet printing box mounting base 16 has a side T-shaped structure, including a vertical plate and a horizontal plate. The inkjet printing box 18 is mounted on the vertical plate, and the cabinet mounting base 23 is connected to the end of the horizontal plate opposite to the vertical plate. Both ends of the horizontal plate are provided with connection holes for connecting to the connecting plate 13. Figures 4-6As shown, the upper and lower sides of the horizontal plate are connected to the vertical plate by angle steel to improve the stability of the inkjet box mounting base 16; both ends of the connecting plate 13 are provided with connecting holes, and the connecting holes at both ends of the connecting plate 13 are respectively connected to the connecting holes on the horizontal plates on both sides by bolts to facilitate assembly and disassembly.

[0032] The inkjet printing module 12 in this embodiment also includes a wire groove sheet metal 15, a cable chain, a protective cover, etc. Figure 3 As shown. The cable tray 15 is mounted on the cabinet mounting base 23 and located on the side of the inkjet cabinet 22 away from the inkjet box 18, effectively protecting the cables from damage. The cable chain can protect the cables and pipes connecting the inkjet box 18 and the inkjet cabinet 22, and the protective cover can protect the inkjet box 18.

[0033] In some embodiments, the lateral movement mechanism includes a lateral rack 24, a lateral gear, and a lateral servo motor. The lateral rack 24 is disposed on the top surface of the movable gantry beam 2 and extends laterally. The lateral servo motor is disposed on the horizontal plate. The lateral gear is connected to the output shaft of the lateral servo motor, and the lateral rack 24 meshes with the lateral gear. The lateral servo motor drives the lateral gear to rotate, and the lateral gear meshes with the lateral rack 24 to drive the printing module 3 to move laterally.

[0034] Furthermore, the movable gantry beam 2 is provided with a first linear guide rail 9 on its side and a second linear guide rail 10 and a circular guide rail 11 on its top surface; a first slider that cooperates with the first linear guide rail 9 is provided on the side of the vertical plate, a second slider that cooperates with the second linear guide rail 10 is provided on the bottom surface of the horizontal plate, and a third slider that cooperates with the circular guide rail 11 is provided on the bottom surface of the cabinet mounting base 23. The first slider is slidably mounted on the first linear guide rail 9, and the second slider is slidably mounted on the second linear guide rail 10, providing guidance for the movement of the inkjet box mounting base 16 and the inkjet box 18 thereon, ensuring that the inkjet module 3 moves in a horizontal linear direction under the drive of the horizontal moving mechanism; the third slider is slidably mounted on the circular guide rail 11, providing guidance for the movement of the cabinet mounting base 23 and the inkjet cabinet 22 thereon, ensuring that the inkjet module 3 moves in a horizontal linear direction under the drive of the horizontal moving mechanism.

[0035] In this embodiment, the printing module 3 is driven by a horizontal servo motor, and the horizontal gear and rack 24 are used for transmission. The first linear guide rail 9, the second linear guide rail 10, and the circular guide rail 11 cooperate with the first slider, the second slider, and the third slider respectively for guidance, so that the printing module 3 can perform precise horizontal movement on the movable gantry beam 2.

[0036] In some embodiments, the inkjet printing box mounting base 16 is provided with a vertical moving mechanism, and the inkjet printing box 18 is slidably mounted on the vertical moving mechanism.

[0037] In this embodiment, the vertical movement mechanism includes a vertical servo motor 19, a ball screw 20, and a slide 17. Both the vertical servo motor 19 and the ball screw 20 are mounted on the vertical plate, and the slide 17 is mounted on the ball screw 20. The printing box 18 is mounted on the slide 17. The vertical servo motor 19 drives the ball screw 20 to move the slide 17 vertically, and the printing box 18 moves precisely up and down vertically with the slide 17. A vertical linear guide rail is also provided on the vertical plate, and a vertical slider is provided on the slide 17, slidably mounted on the vertical linear guide rail, ensuring that the slide 17 moves vertically under the drive of the vertical servo motor 19 and the ball screw 20.

[0038] Furthermore, a laser rangefinder 21 is installed on the printing box 18. Specifically, laser rangefinders 21 can be installed at all four corners of the printing box 18. During the printing process, the laser rangefinder 21 can accurately measure the distance between the printing box 18 and the steel plate 25 in real time and feed it back to the control cabinet 6. The control cabinet 6 receives the distance signal from the laser rangefinder 21 and can precisely control the vertical position of the printing box 18 through the vertical movement mechanism, so that the printing box 18 always maintains a suitable printing height, which can adapt to steel plates of different thicknesses and improve the printing quality.

[0039] like Figure 3 and Figure 4 As shown, a vision system 14 is provided on the side of the printing module 3. In this embodiment, the vision system 14 includes a 3D camera, which is located on the side of the printing module 3. The 3D camera moves laterally and longitudinally with the printing module 3 and can automatically scan from the origin to find the position of the steel plate 25 and accurately locate the edge.

[0040] In some embodiments, safety light curtains 8 are provided on both sides of the movable gantry beam 2 in the transverse direction. For example... Figure 1As shown, safety light curtains 8 are installed on both sides of the movable gantry beam 2 in the horizontal direction to ensure production safety. Further, the safety light curtain 8 includes a light curtain emitter and a light curtain receiver, which are respectively fixed to both ends of the movable gantry beam 2 in the horizontal direction, and the light curtain emitter and the light curtain receiver cooperate to form a light curtain perpendicular to the top surface of the steel plate 25. In this embodiment, the light curtain emitter and the light curtain receiver are arranged opposite each other and respectively fixed to both ends of the movable gantry beam 2 in the horizontal direction by a fixing bracket. The light curtain emitter emits invisible infrared beams, and the light curtain receiver receives the light signals; the two cooperate to form a vertical light curtain.

[0041] Furthermore, the movable gantry beam 2 includes a beam 7 and two vertical supports. Both ends of the beam 7 are connected to the tops of the two vertical supports, and the bottoms of the vertical supports are slidably mounted on the bed 1 via the longitudinal moving mechanism. The printing module 3 is slidably mounted on the beam 7 via the transverse moving mechanism. In this embodiment, the bed 1 consists of two fixed supports arranged parallel to each other longitudinally, and the two vertical supports are slidably mounted on the two fixed supports via two longitudinal moving mechanisms.

[0042] In some embodiments, the longitudinal moving mechanism includes a longitudinal rack, a longitudinal gear, and a longitudinal servo motor. The longitudinal rack is disposed on the corresponding fixed support and extends longitudinally. The longitudinal servo motor is mounted on the corresponding vertical support. The longitudinal gear is connected to the output shaft of the longitudinal servo motor. The longitudinal rack meshes with the longitudinal gear.

[0043] Furthermore, each fixed support is also equipped with a third linear guide rail extending longitudinally, and the vertical support is equipped with a fourth slider that cooperates with the third linear guide rail. The fourth slider is slidably mounted on the third linear guide rail, providing guidance for the movement of the movable gantry beam 2, ensuring that the movable gantry beam 2 moves laterally in a straight line under the drive of the longitudinal moving mechanism.

[0044] This embodiment utilizes a dual-sided longitudinal servo motor synchronous drive, longitudinal gear and rack transmission, and a third linear guide rail and a fourth slider for guidance, enabling precise longitudinal movement of the movable gantry beam 2 on the bed 1. In this embodiment, high-precision servo motors can be used for both the transverse and longitudinal servo motors.

[0045] like Figure 1As shown, the worktable 4 is located between the two fixed supports of the bed 1 and below the crossbeam 7. It is a fixed structure used to support the steel plate 25. The steel plate 25 is placed statically on the worktable 4. The printing box 18 is moved horizontally, vertically, and horizontally by the transverse, longitudinal, and vertical movement mechanisms, thereby marking and printing on the steel plate 25. The control cabinet 6 and the operating table 5 are located on the side of the bed 1. The transverse, longitudinal, and vertical movement mechanisms, as well as the laser rangefinder 21, vision system 14, and operating table 5 are all electrically connected to the control cabinet 6.

[0046] like Figure 1 and Figure 7 As shown, when the width of a single print is half the width of the steel plate 25, the mobile gantry beam 2 can complete the printing of the entire steel plate 25 in one reciprocating motion. The speed of the mobile gantry beam 2 can reach 30m / min. Typically, the maximum length of a steel plate 25 is about 20m, and the printing of the steel plate 25 can be completed in a few minutes. The overall printing time of the steel plate 25 is much less than the one or two hours required for manual handwriting and marking. Furthermore, the width of a single print can be adjusted by adding or removing the printing modules 12 in the printing module 3.
