[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, abutting connections, or integral connections. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] 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.

[0032] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a full-line marking printing machine, including a central control unit, a gantry frame 3, a printing assembly, a distance measuring assembly 10, a Z-axis lifting assembly 4, and an incoming material detection unit 2.

[0033] In this embodiment, the incoming material detection unit 2 is located on the side of the gantry frame 3 where the sheet metal is fed, and the incoming material detection unit 2 is electrically connected to the central control unit. During the conveying process, the sheet metal 1 first passes through the incoming material detection unit 2. The incoming material detection unit 2 detects the length, width, thickness, and position information of the sheet metal 1, and sends this detected sheet metal information to the central control unit. After obtaining the sheet metal information, the central control unit controls the printing assembly to perform the next printing operation. The incoming material detection unit 2 can be a device that can detect the length, width, thickness, and position of the sheet metal in the prior art, and its specific structure will not be described here.

[0034] The printing assembly comprises at least one set, and each set of printing assemblies is connected side-by-side to the gantry frame 3 along the width direction of the sheet material 1 via the Z-axis lifting assembly 4. The ranging assembly 10 is mounted on the printing assembly, and the printing assembly, ranging assembly 10, and Z-axis lifting assembly 4 are all electrically connected to the central control unit. The ranging assembly 10 is used to detect the vertical distance between the printing assembly and the sheet material 1. Specifically, the ranging assembly can be, but is not limited to, a laser ranging sensor. When the sheet material 1 moves to the appropriate position, the ranging assembly senses the distance between the printing assembly and the sheet material 1 and transmits the distance signal to the central control unit. The central control unit then controls the Z-axis lifting assembly 4 to move up and down, thereby ensuring that the printing assembly maintains a suitable printing height. When the sheet material 1 moves to the working position of the printing assembly, the central control unit controls the printing assembly to perform printing operations on the sheet material 1 based on the sheet material information transmitted by the incoming material detection unit 2.

[0035] As an optional implementation method, such as Figure 2As shown, the gantry frame 3 adopts a split structure, including two bases 5, a crossbeam 6, and a maintenance platform 7. The two bases 5 are positioned on either side, and the crossbeam 6 and maintenance platform 7 are mounted above the two bases 5. During operation, the sheet metal 1 passes under the crossbeam 6 and maintenance platform 7 between the two bases 5. Multiple Z-axis lifting components 4 are installed side-by-side on the crossbeam 6 along its axial direction (i.e., the width direction of the sheet metal 1). This split structure design of the gantry frame 3 allows for easier adaptation and assembly with sheet metal production lines.

[0036] In an optimized manner, a step ladder 13 can be installed on the side of the gantry frame 3 to facilitate the inspection and maintenance of equipment such as the Z-axis lifting assembly 4 and the printing assembly installed on the gantry frame 3.

[0037] In addition, in this embodiment, the gantry frame 3 and the incoming material inspection unit 2 can be directly installed on the existing board production line, thus eliminating the need to provide additional space for the full marking and printing machine, saving the floor space required for board production.

[0038] As one specific implementation method, such as Figures 2 to 6 As shown, the printing assembly includes a printing cabinet 8 and a printing box 9. The printing box 9 is mounted on the Z-axis lifting assembly 4. Multiple printing heads 14 are mounted on the base plate of the printing box 9. The printing cabinet 8 is mounted on the maintenance platform 7 of the gantry frame 3. The printing cabinet 8 is electrically connected to the central control unit, and the printing box 9 is electrically connected to the printing cabinet 8. The Z-axis lifting assembly 4 adjusts the printing box 9 to a suitable printing height. Based on the material information detected by the incoming material detection unit 2, the central control unit sends a corresponding working signal to the printing cabinet 8, and the printing cabinet 8 controls the printing heads 14 inside the printing box 9 to perform the corresponding printing work.

[0039] Optimize the above technical solutions, such as Figure 5 and Figure 6 As shown, the multiple printheads 14 on the bottom plate of the print box 9 are arranged in two rows. The two rows of printheads 14 are arranged alternately and have overlapping areas at the intersection, so that the print box 9 has no blind spots in its printing area and no printing breaks, thus improving the printing quality.

[0040] Further optimized technical solutions, such as Figure 7 As shown, the printing box 9 is designed with concave and convex structures at both ends, and the ends of the printing boxes 9 of adjacent printing components are arranged in an alternating pattern. This ensures that the printing heads 14 of multiple printing boxes 9 are arranged in an alternating pattern with overlapping areas at the intersections, so that the printing area covers the entire width of the board 1. When the board 1 passes through, it can be printed without dead angles.

[0041] Optimized implementation methods, such as Figure 3 and Figure 5As shown, multiple sets of ranging components 10 are arranged around each group of printing components. Specifically, the ranging components 10 are arranged around the printing chamber 9, and the area enclosed by these multiple sets of ranging components 10 covers the printing range of this group of printing chambers 9, improving printing accuracy. Specifically, in this embodiment, four sets of ranging components 10 are arranged around each printing chamber 9, respectively at the front, back, left, and right positions of the printing chamber 9.

[0042] In an optional implementation, the Z-axis lifting assembly 4 includes a high-precision servo motor, a linear guide rail assembly, a ball screw, and a slide. The servo motor drives the ball screw to be precisely guided by the linear guide rail assembly, thereby driving the slide to perform precise up-and-down movement. The printing box 9 of each printing assembly is respectively installed on the slide of the corresponding Z-axis lifting assembly 4, and moves up and down with the slide, thereby adjusting the distance between the printing box 9 and the plate 1 running below it, so that the printing box 9 always maintains a suitable printing height.

[0043] In this embodiment, each set of printing boxes is independently controlled to move up and down through a set of Z-axis lifting components. This allows the number of printing boxes to be moved up and down to a suitable printing height based on the width of the board to be processed. For example, the number of printing boxes can be designed and installed on the board production line according to the maximum width of the board to be processed. When processing boards with a smaller width, only the printing boxes corresponding to the smaller width of the board need to be controlled to move up and down to adjust the height for printing. This eliminates the need to design a full-size marking and printing machine for each type of board, greatly reducing production costs.

[0044] Preferably, each Z-axis lifting assembly 4 is designed to move independently along the direction perpendicular to the axis of the crossbeam 6 on the gantry frame 3. This facilitates the disassembly, inspection, and maintenance of the Z-axis lifting assembly 4, and also meets the different printing requirements of the plate 1.

[0045] The optimized technical solution in this embodiment of the full-line marking printer also includes a board position monitoring unit. This board position monitoring unit is electrically connected to the central control unit and is used to monitor the real-time position of the board 1 in the direction of travel, and to feed back the board position information to the central control unit in real time, so that the central control unit can accurately control the printing assembly to print on the board 1. In some embodiments, such as Figure 3 and Figure 4As shown, the board position monitoring unit includes multiple roller encoders 11. One roller encoder 11 is installed at the front and one at the back of the printing box 9 of the printing assembly, forming a group. One or more groups can be configured. When the board 1 travels and presses against the roller encoder 11, the rollers of the encoder 11 rotate with the movement of the board 1. The rotation of the rollers transmits signals to the central control unit in real time. The central control unit receives the signals and determines the real-time position of the board 1 in the direction of travel, thereby controlling the printing box 9 to accurately print on the board 1. The roller encoders 11 can be independently installed at the front and back positions of the printing box 9 via brackets, or they can be directly installed on the printing box 9.

[0046] To avoid the influence of other processes on the board production line on this printing process, the optimized version of the full-line marking printing machine in this embodiment also includes a protective chamber 15. The central control unit is integrated into the side of the protective chamber 15, and the gantry frame 3, printing components, ranging components 10, Z-axis lifting components 4, and incoming material detection unit 2 are all housed within the protective chamber 15. Specifically, as shown... Figure 8 and Figure 9 As shown, the main body of the protective room 15 is composed of a steel structure frame and sheet metal panels. The central control unit includes a control cabinet 12 and an operating table 16. The control cabinet 12 and the operating table 16 are respectively integrated at both ends of the protective room 15. Outward opening doors are provided at both ends of the protective room 15, allowing people to enter and exit to operate and maintain the equipment. Safety locks are provided on the outward opening doors to effectively protect the safety of the operation.

[0047] Taking a 20m×4m sheet material with 80 parts to be processed as an example, the current method of manually writing part information and then manually marking lines takes about 70 minutes. Using existing mobile marking machines or zinc powder marking techniques, it also takes about 30 minutes (excluding transfer time for loading and unloading the sheet). However, using the comprehensive marking and printing machine of this invention, on the same 20m×4m sheet material, printing and marking the same number of parts takes only 3.33 minutes when the sheet material conveying speed is 6m / min. If the sheet material conveying speed is increased, the printing time can be further shortened. Therefore, it can be seen that using the comprehensive marking and printing machine of this invention to print and mark lines on sheet materials greatly improves production efficiency.

[0048] In summary, the comprehensive marking and marking machine provided by this utility model automatically controls the printing components to perform printing and marking work through the central control unit, replacing the existing manual handwriting of part information and drawing of assembly lines. This reduces labor costs and avoids the chance of human error. Furthermore, the printing and marking process is carried out during the material conveying process, saving a lot of time and improving production efficiency.

[0049] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
