Description

Technical Field

[0001] The present invention relates to the technical field of inkjet printers, and in particular to an intelligent gantry type line drawing inkjet printer. Background Art

[0002] Existing small line drawing inkjet printers are installed on a fixed base and draw markings within a limited range in the form of an arm. For example, in an automated inkjet device with the publication number CN217073824U, the inkjet printer nozzle is fixed on a bracket, and the workpiece to be inkjet is moved relative to the inkjet printer in the form of a conveyor belt, etc. to complete the operation. Such an inkjet printer is suitable for inkjet operations on small objects and is not suitable for line drawing inkjet operations on large structural parts.

[0003] Existing gantry type line drawing inkjet printers, that is, the inkjet printer is installed on a gantry, and the inkjet printer can move along the direction of the gantry beam. The gantry runs on a fixed track and can move along the direction perpendicular to the main beam. The combination of the two can perform automatic line drawing inkjet operations on the area under the gantry. In a steel plate intelligent blanking system and method with the publication number CN115533549A, the gantry line drawing inkjet printer performs automatic line drawing inkjet operations on the gantry steel plate. This form of only combining the movement of the gantry and the line drawing machine is more suitable for small area operations, and there are problems with control accuracy for large area operations. For example, for large-scale operations, the gantry has to span the entire operation area, the distance between the two legs is large, that is, the gantry span, volume, and its own equipment mass are large. At the same time, the running distance of the gantry is large, and the overall accuracy of line drawing inkjet decreases, making it difficult to meet the use requirements. Moreover, the installation accuracy of the gantry running track is high, and maintenance is difficult and costly.

[0004] For the gantry type line drawing inkjet printer, the track is a long track composed of multiple short guide rails spliced together. After the track foundation works for a period of time or under the action of external forces, it will produce loose displacement, which will cause errors in the operation control of the gantry, resulting in changes in the straightness or length of the drawn line, and problems such as the drawn pattern being distorted. When the gantry performs line drawing inkjet, the gantry span is large, and there is a certain error in the running synchronization of the two side leg mechanisms. The uncertainty of the error is increased during multiple back-and-forth movements, affecting the processing quality. In addition, the gantry span is large and the self-weight is also large. The running mechanism needs a large power to drive the gantry to run. If the gantry needs to move for each line, it also requires a large amount of energy consumption. Summary of the Invention

[0005] In order to solve the technical problems in the prior art that there are large errors in the operation of the gantry when inkjetting large components and the large gantry span increases energy consumption, the present invention provides an intelligent gantry type line drawing inkjet printer.

[0006] The intelligent gantry type line drawing inkjet printer provided by the present invention adopts the following technical solutions:

[0007] An intelligent gantry type line marking and inkjet coding machine, comprising a gantry and a ground track arranged on the ground. The ground track is two symmetrical tracks fixedly arranged above the ground. The gantry includes a gantry main beam and gantry legs. The gantry main beam is arranged above the ground track, and gantry legs are respectively arranged on both sides of the bottom of the gantry main beam. A gantry running mechanism is installed at the lower part of each gantry leg, and this gantry running mechanism is connected to the ground track. The gantry main beam is driven to move along the ground track through the gantry running mechanism. Among them, a trolley is arranged on the side of the gantry main beam, and a trolley running mechanism is arranged between the side of the gantry main beam and the trolley. The trolley is driven to move along the length direction of the gantry main beam through the trolley running mechanism;

[0008] An inkjet coding machine frame is arranged on the side of the trolley, and an inkjet coding machine is arranged at the bottom of the inkjet coding machine frame. An inkjet coding machine horizontal moving mechanism is arranged between the inkjet coding machine frame and the trolley. The inkjet coding machine at the bottom of the inkjet coding machine frame is driven to make a horizontal movement on the trolley along the direction perpendicular to the side wall of the gantry main beam through the inkjet coding machine horizontal moving mechanism. An inkjet coding machine frame lifting mechanism is arranged between the inkjet coding machine horizontal moving mechanism and the inkjet coding machine frame. The inkjet coding machine at the bottom of the inkjet coding machine frame is driven to make a vertical lifting movement on the trolley through the inkjet coding machine frame lifting mechanism. With the above structure, after the position of the trolley is fixed, the inkjet coding machine can still perform three-dimensional line marking and inkjet coding operations and can perform segmented inkjet coding operations on large components.

[0009] Further, the gantry running mechanism is composed of a running motor and running wheels. The running motor is arranged at the bottom of the gantry leg, and running wheels are also arranged at the bottom of the gantry leg. The running motor is connected to the running wheels and drives the running wheels to rotate. The running wheels are connected to the ground track. The running motor drives the running wheels to rotate, so that the gantry main beam moves along the ground track.

[0010] Further, the trolley running mechanism is composed of a running slider, a driving gear and a running motor. Main beam guide rails are respectively fixedly installed at the upper and lower ends of the side of the gantry main beam. The main beam guide rails are arranged along the length direction of the gantry main beam. A main beam rack is fixedly arranged at the bottom of the main beam guide rail at the upper end of the side of the gantry main beam. The running slider is slidably connected with the main beam slide rail, the driving gear is meshed with the main beam rack, and the running motor is connected to the driving gear and drives the driving gear to rotate.

[0011] Further, an inkjet coding machine horizontal guide rail and an inkjet coding machine horizontal rack are installed on the side of the trolley along the direction perpendicular to the side wall of the gantry main beam. The number of the inkjet coding machine horizontal guide rails is two, which are symmetrically arranged at the upper and lower ends of the side wall of the trolley respectively. An inkjet coding machine horizontal rack is arranged at the upper end of the side wall of the trolley, and the inkjet coding machine horizontal rack is arranged at the bottom of the inkjet coding machine horizontal guide rail at the upper end of the side wall of the trolley. The inkjet coding machine horizontal moving mechanism is connected to the inkjet coding machine horizontal guide rail and the inkjet coding machine horizontal rack.

[0012] Furthermore, the structural arrangement of the horizontal movement mechanism of the inkjet printer is the same as that of the trolley running mechanism.

[0013] Furthermore, lifting guide rails and lifting racks for lifting are installed on the inkjet printer frame. The number of the lifting guide rails is two, which are respectively arranged on both sides of the side wall of the inkjet printer frame. Lifting racks are arranged at the ends of the side walls of the inkjet printer frame. The lifting racks are arranged outside the lifting guide rails. The inkjet printer frame lifting mechanism is connected to the lifting guide rails and the lifting racks.

[0014] Furthermore, the difference between the structure of the inkjet printer frame lifting mechanism and the structure of the trolley running mechanism lies only in the position where the driving gear is arranged. In the inkjet printer frame lifting mechanism, the driving gear is meshed with the lifting rack.

[0015] Furthermore, it further includes an intelligent gantry control system for segmenting large components. A locator is also arranged at the bottom of the inkjet printer frame, and the locator is arranged on the side of the inkjet printer.

[0016] An inkjet printing method for an intelligent gantry type line drawing inkjet printer includes the following steps:

[0017] S1. Divide the graphics on a whole large component that needs to be line-drawn and inkjet-printed into several segmented areas, and then use the intelligent gantry type inkjet printer to operate on one of the segmented areas.

[0018] S2. When inkjet printing, after the gantry main beam moves to the working position of one of the segmented areas, it is fixed. The trolley moves along the gantry main beam to one end of the gantry main beam. By adjusting the horizontal movement of the inkjet printer and the detection locator, a reference position of the segment is found. The trolley then moves to the other end of the gantry main beam. By adjusting the horizontal movement of the inkjet printer and the detection locator, another reference position of the segment is found. In this way, the reference for this segmented line-drawing and inkjet printing is set, so that connection coordinate reference points are sprayed around the segment. The reference points are grouped and marked for connecting the relative coordinates of two segments. The reference points are marked as circles or squares. The segment connection coordinate reference points are inkjet-printed and marked in the previous segment for positioning the reference points of the next segment. The coordinate reference points of the initial first segment are marked when the gantry detects the overall line-drawing and inkjet printing area.

[0019] S3. Make the trolley move and draw lines along the length direction of the gantry main beam, in combination with the horizontal movement of the inkjet printer frame on the trolley in the direction perpendicular to the side wall of the gantry main beam, to complete the line-drawing and inkjet printing operation within the segmented plane.

[0020] In summary, the beneficial effects of the present invention are:

[0021] 1. The present invention drives the main beam of the gantry along the ground track through the gantry running mechanism, drives the trolley to move along the length direction of the main beam of the gantry through the trolley running mechanism, and drives the inkjet printer at the bottom of the inkjet printer rack to move horizontally on the trolley along the direction perpendicular to the side wall of the main beam of the gantry through the horizontal movement mechanism of the inkjet printer, and drives the inkjet printer to move up and down on the trolley through the lifting mechanism of the inkjet printer rack. When in use, the object to be marked by drawing a line and spraying ink does not move, the gantry can run and be positioned on the ground track, the trolley and the inkjet printer can move on the main beam of the gantry, the inkjet printer can move horizontally and vertically relative to the trolley, and through the combined operation of multi-axis movement, large-range three-dimensional line drawing and inkjet spraying can be completed.

[0022] 2. Before drawing and plotting, the present invention controls the operation of the driving structure through the intelligent gantry control system, scans the outer contour of the working object, finds and determines the perimeter and height of the working object, and divides the graph into several segmented areas through the intelligent gantry control system. Each time, inkjet spraying is carried out for one segmented area, and after each segmented operation is completed, it is pieced together into an overall large graph. When carrying out the inkjet spraying operation within one segment, the gantry remains stationary, eliminating the adverse effects of the running error of the gantry on the graph operation and also eliminating the adverse effects of the installation error of the running track of the gantry on the graph operation; the gantry runs in a step-by-step manner. After the gantry moves a step distance, the trolley and the line drawing machine are re-calibrated and positioned. The gantry carries out segmented inkjet spraying work. Positioning reference marks are sprayed at the head and tail positions of each segmented work. Before carrying out the next segment of inkjet spraying, the set positioning reference points of the previous segment are detected, and then the plotting reference points of this segment are completed. The reference points marked at the tail of this segment can be used as the positioning reference for the next segment. In this way, each segment is connected through the reference, eliminating the installation and running errors of the ground track. The large graph is divided into several small graphs through spraying marks, and inkjet spraying is carried out for each line drawing one by one, reducing the round-trip movement of the entire gantry and also reducing errors, thereby improving the operation efficiency and reducing energy consumption.

The ground track 4 is two symmetrically fixed above the ground. The gantry includes a gantry main beam 1 and gantry legs 2. The gantry main beam 1 is arranged above the ground track 4. The two end parts at the bottom of the gantry main beam 1 are rigidly connected to the gantry legs 2 respectively. A gantry running mechanism 3 is installed at the lower part of each gantry leg 2.

The running motor is connected to the running wheels and drives the running wheels to rotate. The running wheels are connected to the ground track 4. The running motor drives the running wheels to rotate, so that the gantry main beam 1 moves along the ground track 4.

[0031] A trolley 10 is provided on the side of the gantry main beam 1, and a trolley running mechanism 12 for driving the trolley 10 to move is provided between the side of the gantry main beam 1 and the trolley 10. Preferably, the trolley running mechanism 12 is composed of a running slider, a driving gear and a running motor. Main beam guide rails 8 are fixedly installed at the upper and lower ends of the side of the gantry main beam 1 respectively. The main beam guide rails 8 are arranged along the length direction of the gantry main beam 1. A main beam rack 9 is fixedly arranged at the bottom of the main beam guide rail 8 at the upper end of the side of the gantry main beam 1. The running slider is slidably connected with the main beam slide rail 8. The driving gear is meshed with the main beam rack 9. The running motor is connected with the driving gear and drives the driving gear to rotate. During use, the driving gear is driven by the running motor to move on the main beam rack 9, so that the trolley moves along the length direction of the gantry main beam 1 on the main beam slide rail 8.

[0032] An inkjet coding rack 19 is provided on the side of the trolley 10. An inkjet printer 11 and a locator 20 are provided at the bottom of the inkjet coding rack 19. The locator 20 is arranged at the side of the inkjet printer 11. Among them, the inkjet printer 11 is used for drawing lines, inkjet coding and spraying patterns on the working object, and the locator 20 is used for detecting and calibrating the reference of each drawn line. An inkjet printer horizontal movement mechanism is provided between the inkjet coding rack 19 and the trolley 10. Inkjet printer horizontal guide rails 13 and an inkjet printer horizontal rack 14 are installed on the side of the trolley 10 in the direction perpendicular to the side wall of the gantry main beam 1. The number of the inkjet printer horizontal guide rails 13 is two, which are symmetrically arranged at the upper and lower ends of the side wall of the trolley 10 respectively. The inkjet printer horizontal rack 14 is arranged at the upper end of the side wall of the trolley 10. The inkjet printer horizontal rack 14 is arranged at the bottom of the inkjet printer horizontal guide rail 13 at the upper end of the side wall of the trolley 10. The inkjet printer horizontal movement mechanism is connected with the inkjet printer horizontal guide rails 13 and the inkjet printer horizontal rack 14. Among them, the setting structure of the inkjet printer horizontal movement mechanism is the same as that of the trolley running mechanism 12, and will not be described repeatedly here. The inkjet printer 11 at the bottom of the inkjet coding rack 19 is driven by the inkjet printer horizontal movement mechanism to make a horizontal movement on the trolley 10 in the direction perpendicular to the side wall of the gantry main beam 1.

[0033] A inkjet printer lifting mechanism 16 is provided between the horizontal movement mechanism 15 of the inkjet printer and the inkjet printer frame 19. A lifting guide rail 17 and a lifting rack 18 for lifting are installed on the inkjet printer frame 19. The number of the lifting guide rails 17 is two, which are respectively arranged on both sides of the side wall of the inkjet printer frame 19. The lifting rack 18 is arranged at the end of the side wall of the inkjet printer frame 19. The lifting rack 18 is arranged outside the lifting guide rail 17. The inkjet printer lifting mechanism 16 is connected to the lifting guide rail 17 and the lifting rack 18. The structure of the inkjet printer lifting mechanism 16 is only different from the structure of the trolley running mechanism 12 in the position where the driving gear is set. The driving gear in the inkjet printer lifting mechanism 16 is meshed with the lifting rack 18. During use, the inkjet printer lifting mechanism drives the inkjet printer 11 at the bottom of the inkjet printer frame 19 to move up and down.

[0034] Among them, the motion tracks in the present invention are all precision linear guide rails, and the motion of the trolley and the inkjet printer is driven by a servo motor, with small motion control errors. By installing the inkjet printer 11 and the position calibration and positioning instrument 20 at the lower part of the inkjet printer frame, while increasing the stroke of the inkjet printer, the distance between the inkjet machine and the nozzle is shortened, improving the inkjet response speed of the inkjet printer and the line drawing accuracy of the inkjet printer.

[0035] When in use, the intelligent gantry type line drawing and inkjet printer can drive the trolley 10 to move along the ground track 4 through the gantry running mechanism 3, and the running direction is perpendicular to the length direction of the gantry main beam 1; the trolley running mechanism 12 drives the trolley 10 to move along the main beam slide rail 8. At this time, the running direction of the trolley 10 is parallel to the length direction of the gantry main beam 1; the inkjet printer horizontal movement mechanism 15 drives the inkjet printer 11 to move horizontally on the trolley 10 along the direction perpendicular to the side wall of the gantry main beam 1. At this time, the horizontal running direction of the inkjet printer 11 on the trolley 10 is perpendicular to the length direction of the side part of the gantry main beam 1; the inkjet printer lifting mechanism 16 can drive the inkjet printer 11 to move up and down on the trolley 10; through the above structure, when the gantry is fixed, the inkjet printer 11 can perform three-dimensional space line drawing and inkjet operations.

[0036] When in use, the intelligent gantry type line drawing and inkjet printer can perform line-by-line scanning spraying or directly run point-to-point obliquely. While the trolley 10 is moving, the line drawing and inkjet printer 11 also moves horizontally. The combination of the two can draw plane oblique lines or curves. The combination of the movement of the trolley 10, the horizontal movement and the lifting movement of the line drawing and inkjet printer 11 can draw space oblique lines or curves.

[0037] In order to eliminate the gantry running error, the second embodiment of the present invention refers to Figure 1 and Figure 4As shown in the figure, the present invention also provides an intelligent gantry control system for segmenting large component 5. When performing line drawing and inkjet coding on the intelligent gantry, the graphics on a whole large component 5 that needs line drawing and inkjet coding are divided into several segmented areas. Then, an intelligent gantry type inkjet printer is used to operate on one of the segmented areas. During the operation, after the gantry main beam 1 moves to the working position of one of the segmented areas 6 and is fixed, the trolley 10 moves along the gantry main beam 1 to one end of the gantry main beam 1. By adjusting the horizontal movement of the inkjet printer 11 and the detection and positioning instrument 20, a reference position of the segment is found. Then the trolley 10 moves to the other end of the gantry main beam 1. By adjusting the horizontal movement of the inkjet printer and the detection and positioning instrument 20, another reference position of the segment is found. In this way, the reference for this segmented line drawing and inkjet coding is set, and the trolley 10 moves along the length direction of the gantry main beam 1 for line drawing, combined with the horizontal movement of the inkjet printer rack 19 on the trolley 10 perpendicular to the side of the gantry main beam 1, to complete the line drawing and inkjet coding operation within the segmented plane. When performing line drawing and inkjet coding for this segment, a new reference point 7 is simultaneously set as the position reference point 7 for the next segment. In this way, when performing each segmented operation, first find the reference point 7 left by the previous segment, perform line drawing and inkjet coding, and set a new reference point 7 for the next segment reference.

[0038] For the above-mentioned intelligent gantry type line drawing and inkjet printer, during the line drawing and inkjet coding operation within one segment, the gantry is fixed, eliminating the adverse effects of the gantry operation error on the graphic operation and also eliminating the adverse effects of the gantry operation track installation error on the graphic operation. After the operation of this segment is completed, the gantry makes a stepping movement, and the distance of the stepping movement is equal to the width of one segment. After the gantry moves to the next segment position and is braked and fixed again, the gantry operation error is effectively eliminated.

[0039] In the third embodiment of the present invention, refer to Figure 1 and Figure 4 As shown in the figure, before line drawing and plotting in the present invention, the driving structure is controlled to operate through the intelligent gantry control system to scan the outer contour of the operation object, find and determine the perimeter and height of the operation object, and divide the graphics into several segmented areas through the intelligent gantry control system. Each time, line drawing and inkjet coding are performed on one segmented area, and after completing the segmented operations one by one, they are pieced together into an overall large graphic. Connecting coordinate reference points 7 are sprayed around each segment, and the reference points 7 are grouped and marked for connecting the relative coordinates of two segments. The marking of the reference point 7 can be circular or square. The connecting coordinate reference points 7 of the segments are marked by inkjet coding in the previous segment for positioning the reference point 7 of the next segment. The coordinate reference points 7 of the initial first segment are marked when the gantry detects the overall line drawing and inkjet coding area.

[0040] For large-scale line spraying and coding, the intelligent gantry line drawing machine divides it into several segments, decomposes the large graph into several segments, which can avoid the gantry running back and forth and reduce the round-trip movement of the trolley 10. In this way, it can not only eliminate the installation error of the ground track 4 and the mechanism error of the gantry running 3, but also reduce the energy consumption required for the movement of the heavier gantry. By connecting the coordinate reference points 7 of each segment, it is used to determine the relative coordinates between two adjacent segments, so that the graphic of each segment can be accurately spliced into a complete large graph, avoiding graphic deformation or dislocation and ensuring the quality of the overall graph.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Each component mentioned in the present invention is a common technology in the existing field. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.

In this way, the reference for the line-drawing and inkjet-coding of this segmentation is set, so that the connection coordinate reference points (7) are inkjet-coded around the segmentation. Group-identify the reference points (7) for connecting the relative coordinates of the two segments. The reference points (7) are marked as circular or square; Connect the segmentation connection coordinate reference points (7), and inkjet-code and mark them in the previous segmentation for positioning the reference points (7) in the next segmentation. The coordinate reference points (7) of the initial first segmentation are marked when the gantry detects the overall line-drawing and inkjet-coding area; S3. Make the trolley (10) move and draw lines along the length direction of the gantry main beam (1), in combination with the horizontal movement of the inkjet coding rack (19) on the trolley (10) in the direction perpendicular to the side wall of the gantry main beam (1), to complete the line-drawing and inkjet-coding operation within the segmented plane.
