Description

[Technical field]

[0001] The utility model relates to the field of printers, in particular to a visual positioning guide belt type flatbed digital printer. [Background Technology]

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings.

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0032] like Figures 1-10 As shown, a visual positioning guide belt type flatbed digital printer includes a machine tool 1, a beam 2 arranged above the machine tool 1 and a printing carriage assembly 3 for printing patterns. The machine tool 1 is provided with a conveyor guide belt assembly 4 for driving the printing carrier to move longitudinally, a suction assembly 5 for sucking air to adsorb the printing carrier on the conveyor guide belt assembly 4, and a beam motion assembly 6 for driving the beam 2 to move longitudinally. The beam 2 is provided with a printing carriage motion assembly 7 for driving the printing carriage assembly 3 to move horizontally and vertically. A scanning camera 8 for scanning the position and placement status of the printing carrier is provided on one side of the printing carriage motion assembly 7. The machine tool 1 is provided with a control The suction air component 5 works to absorb the printing carrier and controls the conveying guide belt component 4, the beam movement component 6, the printing vehicle movement component 7 and the printing vehicle component 3 to print the pattern on the printing carrier and send it out according to the scanning information of the scanning camera 8; the machine tool 1 is provided with a material discharge lifting component 10 connected to the control component 9 for lifting the fed printing carrier, the beam 2 is provided with a suction cup component 11 connected to the control component 9 for sucking up the printing carrier and sending it into the conveying guide belt component 4 as the beam 2 moves, and the beam 2 is provided with a suction cup movement component 12 connected to the control component 9 for driving the suction cup component 11 to move vertically.

[0033] During printing, the print carrier is placed on the material discharge lifting assembly 10, and the control assembly 9 controls the material discharge lifting assembly 10 to work and feed the print carrier into the printer. Then the beam movement assembly 6 drives the beam 2, the suction cup assembly 11 and the suction cup movement assembly 12 to move to the upper side of the print carrier, and the suction cup movement assembly 12 drives the suction cup assembly 11 to move down, and the print carrier is sucked up by the suction cup assembly 11. Then the beam movement assembly 6 drives the beam 2 and the print carrier to move to the conveyor guide assembly 4, and places the print carrier on the printing area of ​​the conveyor guide assembly 4. At the same time, the suction assembly 5 works to adsorb the print carrier on the conveyor guide assembly 4. Then the beam movement assembly 6 drives the beam 2 to move and the printing vehicle movement assembly 7 drives the printing vehicle assembly 3, so that the camera 8 scans the position and placement status information of the print carrier, and the control assembly 9 prints the print pattern according to the print carrier position and placement status information scanned by the camera 8.

[0034] When the print carrier is a sheet-type print carrier, the control component 9 controls the crossbar motion component 6 and the print carriage motion component 7 based on the position and placement information of the print carrier scanned by the camera 8 to drive the print carriage component 3 to perform three-dimensional motion to print the printed pattern onto the print carrier. After printing is completed, the conveyor guide component 4 is controlled to operate and deliver the print carrier. When the print carrier is a three-dimensional print carrier such as a handicraft, the control component 9 controls the conveyor guide component 4 to drive the print carrier to perform stepping motion based on the position and placement information of the print carrier scanned by the camera 8, and simultaneously controls the print carriage motion component 7 to drive the print carriage component 3 to perform horizontal and vertical motion to print the printed pattern on the print carrier. This achieves the function of printing printed patterns on both sheet-type print carriers and three-dimensional print carriers. In this case, the print carrier can be placed directly into the printing area of ​​the conveyor guide component 4 by a human, and the print carrier can be removed by the human body after printing is completed.

[0035] like Figure 1 As shown, the machine tool 1 is provided with a blowing assembly 13 connected to the control assembly 9 and configured to blow air toward the unloading and lifting assembly 10, located between the conveyor guide assembly 4 and the unloading and lifting assembly 10. By blowing air toward the sheet-mounted printing carrier, the sheet-mounted printing carrier is separated from the unloading and lifting assembly 10, allowing the suction assembly 5 to pick up the sheet-mounted printing carrier and move it.

[0036] like Figure 3 As shown, the conveyor belt assembly 4 includes a driving roller 41 and a driven roller 42, each mounted on the machine tool 1. A belt guide motor 43 is connected to one side of the driving roller 41. A mesh belt 44 is disposed between the driving roller 41 and the driven roller 42. The belt guide motor 43 is connected to the control assembly 9. The belt guide motor 43 is a stepping motor. In actual use, the belt guide motor 43 drives the driving roller 41 to rotate, which, in conjunction with the driven roller 42, drives the mesh belt 44 in stepping motion, thereby driving the print media in stepping motion.

The air suction platform 51 is connected with the air suction end of the air suction fan 52 through an air suction connecting pipeline 54. The air suction connecting pipeline 54 is provided with an adjusting valve 55 for adjusting the air volume. The air suction fan 52 is connected with the control assembly 9. In actual use, the air suction fan 52 works to suck the air in the air suction platform 51 through the air suction connecting pipeline 53. At this time, the air between the mesh belt 44 and the printing carrier is sucked through the air suction holes 53 on the top surface of the air suction platform 51, so that the printing carrier is adsorbed on the mesh belt 44, thereby enabling the printing carrier to step with the mesh belt 44.

[0038] As shown in Figures 3-4 , the cross beam movement assembly 6 comprises longitudinal guide rails 61 and longitudinal ball screws 62 arranged longitudinally on both sides of the machine tool 1 respectively. The longitudinal guide rails 61 are provided with longitudinal movement sliding blocks 63. The cross beam 2 is arranged on the two longitudinal movement sliding blocks 63. The longitudinal ball screws 62 are provided with cross beam movement ball nuts 64 connected with the longitudinal movement sliding blocks 63. The machine tool 1 is provided with a cross beam movement motor 65. The cross beam movement motor 65 is connected with the longitudinal ball screws 62 on both sides through a cross beam movement synchronous belt 66. The front and rear sides of one longitudinal movement sliding block 63 are respectively provided with cross beam movement limiting baffles 67. The machine tool 1 is provided with front side cross beam photoelectric positioning switches 68 and rear side cross beam photoelectric positioning switches 69 on the front and rear sides of the longitudinal ball screws 62 respectively. The cross beam movement motor 65, the front side cross beam photoelectric positioning switches 68 and the rear side cross beam photoelectric positioning switches 69 are connected with the control assembly 9 respectively. The cross beam movement motor 65 is a servo motor. In actual use, the cross beam movement motor 65 works to drive the longitudinal ball screws 62 on both sides to rotate through the cross beam movement synchronous belt 66, so that the cross beam movement ball nuts 64 drive the longitudinal movement sliding blocks 63 and the cross beam 2 to move along the longitudinal guide rails 61, thereby enabling the cross beam 2 to move longitudinally along the conveying guide belt assembly 4 and the feeding lifting assembly 10. At the same time, the cross beam movement limiting baffles 67 limit the maximum movement positions of the front side and the rear side of the cross beam 2 through the front side cross beam photoelectric positioning switches 68 and the rear side cross beam photoelectric positioning switches 69.

[0039] As shown in Figures 5-7As shown, the printing carriage movement assembly 7 comprises a transverse guide rail 71 transversely arranged on the cross beam 2, a transverse movement slider 72 arranged on the transverse guide rail 71, a printing carriage connecting plate 73 arranged on the transverse movement slider 72, a transverse movement belt 74 arranged transversely on the cross beam 2 and driving the printing carriage connecting plate 73 to move along the transverse guide rail 71, a transverse movement motor 75 driving the transverse movement belt 74 to move, a vertical guide rail 76 arranged vertically on the printing carriage connecting plate 73, a vertical ball screw 77 arranged vertically on the printing carriage connecting plate 73, a vertical movement slider 78 arranged on the vertical guide rail 76, the printing carriage assembly 3 arranged on the vertical movement slider 78, a printing carriage ball nut seat 79 arranged on the vertical ball screw 77 and connected with the printing carriage assembly 3, and a vertical movement motor 710 driving the vertical ball screw 77 to rotate; the cross beam 2 is provided with a grating strip 711 arranged transversely and a transverse photoelectric positioning switch 712 arranged at the initial transverse position of the printing carriage assembly 3, the printing carriage connecting plate 73 is provided with a grating head 713 sleeved on the grating strip 711 to detect the movement position and a transverse positioning baffle 714 matched with the transverse photoelectric positioning switch 712, the printing carriage connecting plate 73 is provided with a printing carriage vertical limiting baffle 715, the back of the printing carriage assembly 3 is provided with an upper photoelectric positioning switch 716 and a lower photoelectric positioning switch 717 arranged on the upper and lower sides respectively, which are matched with the printing carriage vertical limiting baffle 715 to position the maximum vertical movement position and the minimum vertical movement position of the printing carriage assembly 3, and the transverse movement motor 75, the vertical movement motor 710, the transverse photoelectric positioning switch 712, the grating head 713, the upper photoelectric positioning switch 716 and the lower photoelectric positioning switch 717 are connected with the control assembly 9 respectively. In actual use, when the printing carriage assembly 3 needs to move transversely, the transverse movement motor 75 works to drive the transverse movement slider 72 and the printing carriage connecting plate 73 to move along the transverse guide rail 71 through the transverse movement belt 74, so that the printing carriage assembly 3 moves transversely on the cross beam 2. Meanwhile, the transverse movement position of the printing carriage assembly 3 can be accurately detected through the cooperation of the grating strip 711 and the grating head 713, and the printing carriage assembly 3 can be reset to the initial transverse position waiting for printing through the cooperation of the transverse photoelectric positioning switch 712 and the transverse positioning baffle 714; similarly, when the printing carriage assembly 3 needs to move vertically, the vertical movement motor 710 arranged on the printing carriage connecting plate 73 works to drive the vertical ball screw 77 to rotate, the vertical movement slider 78 and the printing carriage assembly 3 move along the vertical guide rail 76 through the printing carriage ball nut seat 79, so that the printing carriage assembly 3 moves vertically on the cross beam 2, and the maximum vertical movement position and the minimum vertical movement position of the printing carriage assembly 3 are limited through the cooperation of the printing carriage vertical limiting baffle 715 and the upper photoelectric positioning switch 716 and the lower photoelectric positioning switch 717. In this case, the printing carriage assembly 3 realizes three-dimensional movement through the cooperation of the cross beam movement assembly 6 and the printing carriage movement assembly 7.

A support bracket 34 is mounted on the crossbeam 2, located in the standby position of the carriage assembly 3. Multiple ink pads 35 are mounted on the support bracket 34, corresponding to the print heads 32. A pad height adjustment assembly 36 is also provided on the support bracket 34 for adjusting the height of the ink pads 35. The print heads 32 and UV lamps 33 are each connected to a control assembly 9.
