Description

Technical Field

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

[0002] An inkjet printer is a device that, through software control, uses non-contact inkjet technology to identify products or packaging. Modern inkjet printers can achieve printing of various fonts, graphics, and barcodes, and can be seamlessly integrated with automated production lines to achieve automated identification production. Driven by market demand, the market scale of inkjet printers has been increasing year by year. At the same time, with the improvement of environmental awareness, environmentally friendly inks and sustainable inkjet technologies have also become the development trend of the market.

[0003] Regarding inkjet printer technology, there are many existing technologies, for example:

[0004] According to the Chinese patent application number: CN217073824U, specifically an automated inkjet device. The inkjet printer nozzle is fixed on a bracket, and the workpiece to be inkjet passes through a conveyor belt or other forms to move relative to the inkjet printer to complete the operation. Such an inkjet printer is suitable for inkjet operations on small objects and not suitable for line drawing inkjet operations on large structural parts.

[0005] Existing gantry type line drawing inkjet printers, that is, the inkjet printer is installed on a gantry. The inkjet printer can move along the direction of the gantry beam, and 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. A steel plate intelligent blanking system and method with the publication number CN115533549A, in which 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. There are control accuracy problems 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 is large, and its own equipment mass is heavy. At the same time, the running distance of the gantry is large, and the overall accuracy of line drawing and inkjetting 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.

[0006] For traditional gantry type line drawing inkjet printers, due to the loosening and displacement of the track foundation after working for a period of time or under the action of external forces, this will cause control errors in the gantry operation, resulting in changes in the straightness or length of the drawn line, and problems such as the drawn graphics being distorted. When the gantry performs line drawing and inkjetting, 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, reducing the processing quality. In addition, due to the large gantry span and its own large weight, a large power is required for the running mechanism to drive the gantry to run. If the gantry needs to move for each line, a large amount of energy is also required. Summary of the Invention

[0007] In view of the technical problems existing in the prior art, the present invention provides an intelligent gantry type line drawing and inkjet printer, which solves the problems that the simultaneous movement of the gantry and the spraying mechanism is likely to increase instability, reduce the spraying quality, and the large energy consumption caused by the multiple movements of the gantry.

[0008] To achieve the above object, the present invention provides an intelligent gantry type line drawing and inkjet printer, including a ground track. Above the ground track, there is a gantry. On one side of the gantry, there is a moving trolley. On one side of the moving trolley, there is an inkjet printer frame. The outside of the inkjet printer frame is slidably connected with a moving plate. Inside the moving plate, there are respectively fixedly connected an inkjet printer and a locator. On one side of the moving trolley, the inkjet printer frame and the moving plate, there are all fixedly connected with sliders. On one side of the gantry near the front end, there is a fixedly connected control mechanism.

[0009] The beneficial effects of the present invention are as follows:

[0010] 1. Before line drawing and plotting, scan the outer contour of the operation object, find and determine the perimeter and height of the operation object. The control system divides the graph into segments, sets the starting reference point of the graph, and the gantry performs line drawing and inkjet spraying operations on this segmented graph. At the same time, make a reference point mark at the connection of this segment and the next segment as the connection reference between the next segmented graph and this segment.

[0011] 2. During line drawing and inkjet spraying operations, the gantry remains stationary. The moving trolley can move parallel to the length direction of the gantry. The inkjet printer frame can move horizontally and lift on the moving trolley. Through the combined movement of the moving trolley along the length direction of the gantry and the inkjet printer frame making a movement perpendicular to the gantry direction on the moving trolley, the operation within the segmented plane can be completed. At the same time, combined with the lifting movement, the three-dimensional line drawing and inkjet spraying operation within the segment can be completed, eliminating the adverse effects of the gantry operation error on the graphic operation, and also eliminating the adverse effects of the installation error of the gantry operation track on the graphic operation. It can reduce the number of gantry operations, reduce energy consumption, and also reduce the impact of the back-and-forth movement of the gantry on the passage of other equipment and personnel.

[0012] 3. The inkjet spraying operation is mainly completed by the coordinated movement of the moving trolley and the inkjet printer frame. The moving trolley and the inkjet printer frame are small in mass, have rapid motion control, and high operation efficiency. The motion tracks of the moving trolley and the inkjet printer frame are both precision linear guide rails. The motion drive of the moving trolley and the inkjet printer frame is a servo motor and a dimension wheel and rack, and the motion control error is small.

[0013] On the basis of the above technical solutions, the present invention can also be improved as follows.

[0014] Preferably, there are several ground tracks, and two ground tracks are fixedly connected by bolts. The gantry moves inside the ground track through a first driving mechanism.

[0015] The beneficial effect of adopting the above further solution is that the moving range of different lengths of the gantry can be achieved by adjusting the length of the track.

[0016] Preferably, a first guide rail is fixedly connected to the upper end of one side of the gantry, a first rack is fixedly connected to the lower end of one side of the gantry, the moving trolley is meshed and connected with the first rack through a second driving mechanism, a second guide rail is fixedly connected to the upper end of one side of the moving trolley, a second rack is fixedly connected to the lower end of one side of the moving trolley, the inkjet printing frame is meshed and connected with the second rack through a third driving mechanism, a third guide rail is fixedly connected to one side of the inkjet printing frame, a third rack is fixedly connected to one side of the inkjet printing frame, and the moving plate is meshed and connected with the third rack through a fourth driving mechanism.

[0017] The beneficial effect of adopting the above further solution is that it can enable the intelligent gantry type line drawing and inkjet printer to perform three-dimensional space line drawing and inkjet printing operations, and the inkjet printing operation is mainly completed by the coordinated movement of the moving trolley and the inkjet printing frame. The moving trolley and the inkjet printing frame are small in mass, quick in motion control, high in operation efficiency, and the motion driving mechanism is a servo motor, a sizing wheel and a rack, with small motion control error.

[0018] Preferably, the slider on one side of the moving trolley slides inside the first guide rail, the slider on one side of the inkjet printing frame slides inside the second guide rail, the slider on one side of the moving plate slides inside the third guide rail, and the slider includes a limit block, and the limit block limits the sliding position of the slider.

[0019] The beneficial effect of adopting the above further solution is that the motion tracks of the moving trolley, the inkjet printing frame and the moving plate are all precision linear guide rails, which ensures the stability during the movement and the operation quality of the inkjet printer.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] The object of the line drawing and inkjet printing operation is fixed, and the line drawing and inkjet printer moves three-dimensionally to complete the three-dimensional solid line drawing and inkjet printing operation.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] Please refer to Figures 1-5As shown in the figure, this embodiment provides an intelligent gantry type line drawing and inkjet printer. Considering the traditional gantry type line drawing and inkjet printer, due to the loosening displacement of the track foundation after working for a period of time or under the action of external forces, this 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 deformation of the drawn graphics. When the gantry is used for line drawing and inkjet printing, the gantry has a large span, and there are certain errors in the synchronous operation of the two side leg mechanisms. The uncertainty of the error is increased during multiple back-and-forth movements, reducing the processing quality. In addition, the gantry has a large span and a large self-weight, and a large power is required for the operating mechanism to drive the gantry to run. If the gantry needs to move for each line, a large amount of energy consumption is also required. Therefore, this embodiment includes a ground track 1, a gantry 2 is arranged above the ground track 1, a moving trolley 3 is arranged on one side of the gantry 2, an inkjet printing frame 4 is arranged on one side of the moving trolley 3, a moving plate 44 is slidably connected to the outside of the inkjet printing frame 4, and an inkjet printer 46 and a positioning instrument 47 are respectively fixedly connected inside the moving plate 44 to improve the inkjet response speed of the inkjet printer 46 and the line drawing accuracy of the inkjet printer 46. Sliders 5 are fixedly connected to one side of the moving trolley 3, the inkjet printing frame 4, and the moving plate 44. A control mechanism 6 is fixedly connected to one side of the gantry 2 near the front end. The precise movement of the gantry 2, the moving trolley 3, and the inkjet printing frame 4 is controlled through the control mechanism 6. Through the combination of multi-axis movements, the intelligent inkjet printer can perform large-area three-dimensional line drawing and inkjet printing operations, and is mainly suitable for large-scale operations. The large graphics are divided into multiple segments and multiple regions, and each segment is completed one by one to form an overall graphic. Among them, two reference positions for segmentation are found through the control mechanism 6, so that the reference for this segmented line drawing and inkjet printing is set. Through the combined movement of the gantry 2 moving along the direction parallel to the gantry 2 and the inkjet printing frame 4 moving horizontally in the direction perpendicular to the gantry 2 on the moving trolley 3, the segmented in-plane line drawing and inkjet printing operation can be completed.

[0036] The improvement of this embodiment lies in that: through the combination of multi-axis movements, the intelligent inkjet printer can perform large-area three-dimensional line drawing and inkjet printing operations, and is mainly suitable for large-scale operations. The large graphics are divided into multiple segments and multiple regions, and each segment is completed one by one to form an overall graphic. The inkjet printing operation is mainly completed by the coordinated movement of the moving trolley 3 and the inkjet printing frame 4. The moving trolley 3 and the inkjet printing frame 4 have a small mass, rapid movement control, and high operation efficiency. During the process, the gantry 2 remains stationary, eliminating the adverse effects of the operation error of the gantry 2 on the graphic operation. At the same time, the number of times the gantry 2 runs can be reduced, the energy consumption can be reduced, and the influence of the back-and-forth movement of the gantry 2 on the passage of other equipment and personnel can also be reduced.

[0037] Specifically, considering the different sizes of the workpieces to be drawn, in order to meet the line drawing work of the inkjet printer for workpieces of different sizes, several ground tracks 1 are provided. The two ground tracks 1 are fixedly connected by bolts 11. The gantry 2 moves inside the ground track 1 through the first driving mechanism 21, and the moving range of the gantry 2 with different lengths is realized by adjusting the length of the track.

[0038] To achieve the automatic movement of the inkjet printer and its stability during movement, and to reduce problems such as the deformation of the drawn graphics and the degradation of the line-drawing quality caused by movement errors, a first guide rail 22 is fixedly connected to the upper end of one side of the gantry 2, and a first rack 23 is fixedly connected to the lower end of one side of the gantry 2. The moving trolley 3 is meshed and connected to the first rack 23 through a second driving mechanism 31. A second guide rail 32 is fixedly connected to the upper end of one side of the moving trolley 3, and a second rack 33 is fixedly connected to the lower end of one side of the moving trolley 3. The inkjet printer frame 4 is meshed and connected to the second rack 33 through a third driving mechanism 41. A third guide rail 42 is fixedly connected to one side of the inkjet printer frame 4, and a third rack 43 is fixedly connected to one side of the inkjet printer frame 4. The moving plate 44 is meshed and connected to the third rack 43 through a fourth driving mechanism 45. The running direction of the gantry 2 is parallel to the ground track 1, the running direction of the moving trolley 3 is parallel to the direction of the gantry 2, the running direction of the inkjet printer frame 4 is perpendicular to the gantry 2, and the moving plate 44 drives the inkjet printer 46 to move up and down. In this way, it can be realized that the intelligent gantry type line-drawing inkjet printer can perform three-dimensional space line-drawing inkjet operations, and the inkjet operation is mainly completed by the coordinated movement of the moving trolley 3 and the inkjet printer frame 4. The moving trolley 3 and the inkjet printer frame 4 are small in mass, quick in motion control, and high in operation efficiency.

[0039] To ensure the stability of the movement of the moving trolley 3, the inkjet printer frame 4 and the moving plate 44 and reduce the errors generated by the movement, the slider 5 on one side of the moving trolley 3 slides inside the first guide rail 22, the slider 5 on one side of the inkjet printer frame 4 slides inside the second guide rail 32, and the slider 5 on one side of the moving plate 44 slides inside the third guide rail 42. The slider 5 includes a limit block 51, and the limit block 51 limits the sliding position of the slider 5, so that the movement tracks of the moving trolley 3, the inkjet printer frame 4 and the moving plate 44 are all precision linear guide rails, and the movement driving mechanism is a servo motor, a sizing wheel and a rack, and the movement control error is small.

[0040] As shown above, the working principle of this solution is as follows:

[0041] First, the workpiece is placed between two ground rails 1. According to the actual size of the workpiece, multiple ground rails 1 are connected by bolts 11 to adjust the length of the moving rail to meet the processing requirements of different workpieces. When operating on one segmented area, the gantry 2 moves to the working position of the large segmented area through the first driving mechanism 21. After the position is determined, it is fixed. The moving trolley 3 can move from one end of the gantry 2 to the other end. Adjust the horizontal movement of the inkjet printer 46 and the locator 47 to find a reference position of the segment. Then the moving trolley 3 moves to the other end of the gantry 2 and adjusts the horizontal movement of the inkjet printer 46 and the locator 47 to find another reference position of the segment. In this way, the reference for line drawing and inkjet printing of this segment is set. Then, through the combined movement of the moving trolley 3 moving along the length direction of the gantry 2 and the inkjet printing frame 4 making a horizontal movement perpendicular to the gantry 2 direction on the moving trolley 3, the line drawing and inkjet printing operation within the segment plane can be completed. When performing line drawing and inkjet printing in this segment, new reference points are simultaneously set as the position reference points for the next segment. In this way, when operating on each segment, first find the reference points left by the previous segment, then perform line drawing and inkjet printing, and make marks for the next segment's reference. During this process, the moving trolley 3 is meshed and connected with the first rack 23 through the second driving mechanism 31, the inkjet printing frame 4 is meshed and connected with the second rack 33 through the third driving mechanism 41, and the moving plate 44 is meshed and connected with the third rack 43 through the fourth driving mechanism 45. The moving trolley 3 and the inkjet printing frame 4 are small in mass, with rapid motion control and high operation efficiency. Moreover, both move inside the guide rail through the slider 5 and the limit block 51, making the motion tracks of the moving trolley 3, the inkjet printing frame 4, and the moving plate 44 all precision linear guide rails. The motion driving mechanism is a servo motor, a sizing wheel, and a rack, with small motion control errors. During this process, the gantry 2 remains stationary, eliminating the adverse effects of the gantry 2's running errors on the graphic operation and also eliminating the adverse effects of the installation errors of the gantry 2's running track on the graphic operation. After the operation of this segment is completed, the gantry 2 makes a stepping motion, and the distance of the stepping motion is equal to the width of one segment. After the gantry 2 moves to the position of the next segment and is braked and fixed again, it can reduce the number of times the gantry 2 runs, reduce energy consumption, and also reduce the impact of the gantry 2's back-and-forth movement on the passage of other equipment and personnel.
