Description

Technical Field

[0001] This utility model relates to the field of inkjet printing technology, and in particular to an automatic inkjet printing device. Background Technology

[0002] An inkjet printer is an industrial marking device, primarily used for printing markings on products or semi-finished products during the production process. For example, CN117325566B discloses an automatic inkjet printer for flexible substrates and its automatic coding method. The automatic inkjet printer includes a frame, with a worktable fixedly installed on the upper layer and an inkjet printer mounted in the middle layer. The inkjet printer consists of a visual recognition device, an automatic inkjet printer, and a curing and drying device. The inkjet printer has a base plate, on which the visual recognition device, the automatic inkjet printer, and the curing and drying device are all mounted.

[0035] like Figure 3 and Figure 4 As shown, the coding assembly 30 includes a slide plate 31, a lifting plate 32, and a coding device 33. The slide plate 31 is slidably mounted on the frame 12, the lifting plate 32 is slidably mounted on the slide plate 31, and the coding device 33 is mounted on the lifting plate 32. The coding device 33 is used to spray code onto the material to be coded. Optionally, the lifting plate 32 is arranged in an "L" shape. The coding device 33 is used to spray a QR code onto the material to be coded. In one embodiment, the coding assembly 30 further includes a telescopic power element 34, a vertical plate 35, a lateral movement power element 36, a lateral movement gear 37, and a lateral movement rack 38. The telescopic power element 34 is mounted on the lifting plate 32 and is used to drive the coding device 33 to move closer to or away from the pressure plate 21. The vertical plate 35 is mounted on the slide plate 31, the lateral movement power element 36 is mounted on the vertical plate 35, the lateral movement gear 37 is mounted on the output end of the lateral movement power element 36, and the lateral movement rack 38 is mounted on the frame 12. The lateral movement gear 37 meshes with the lateral movement rack 38. The lateral movement power element 36 drives the lateral movement gear 37 to rotate, and the lateral movement gear 37 and the lateral movement rack 38 cooperate to drive the slide plate 31 to move.

[0036] In one embodiment, the coding assembly 30 further includes a mounting plate 39, a lifting power element 31a, a lifting gear 32a, and a lifting rack 33a. The mounting plate 39 is mounted on the sliding plate 31, the lifting power element 31a is mounted on one end of the mounting plate 39, the lifting gear 32a is mounted on the output end of the lifting power element 31a, and the lifting rack 33a is mounted on the lifting plate 32. The lifting gear 32a meshes with the lifting rack 33a. The lifting power element 31a drives the lifting gear 32a to rotate, and the lifting gear 32a and the lifting rack 33a cooperate to drive the lifting plate 32 to rise and fall. The coding assembly 30 also includes two guide rails (not shown in the figure), which are respectively mounted on both sides of the lifting plate 32. One guide rail is connected to the upright plate 35, and the other guide rail is connected to the mounting plate 39.

[0037] like Figure 4 As shown, the coding assembly 30 also includes a camera 34a, which is mounted on the lifting plate 32. The camera 34a is used to locate the coding position. Optionally, the camera 34a identifies the material to be coded and selects the coding position, such as selecting a position without lines, to ensure that the printed code is clear and complete. The coding assembly 30 also includes a barcode reader 35a, which is mounted on the lifting plate 32. The barcode reader 35a is used to identify the printed code, thereby detecting the printing quality of the code and ensuring that the code is identifiable. Optionally, the camera 34a and the barcode reader 35a are respectively mounted on both sides of the coding machine 33.

[0038] In operation, the conveyor belt 13 transports the material to be printed until the position sensor 17 detects the end of the material. At this point, the conveyor belt 13 stops transporting, and the downward pressing power element 24 drives the base plate 23 to descend, thereby driving the pressure plate 21 to descend until the bottom end of the pressure plate 21 touches the receiving material. Moreover, when transporting the material, the push plate 22 is located below the conveyor belt 13 to prevent obstruction of the material transport. Next, the lifting power element 26 drives the crossbeam 25 to rise, thereby driving the push plate 22 to pass through the worktable 11. As the push plate 22 continues to rise, it flips the material to be printed from the worktable 11 around the bottom end of the pressure plate 21 to one side of the pressure plate 21. At this time, the push plate 22 and the pressure plate 21 respectively touch the two sides of the receiving material. Then, the lifting power component 31a drives the lifting plate 32 down to the processing station. The camera 34a scans the material to be printed, identifies it, and selects the seamless position as the printing position. Next, the lateral movement power component 36 drives the slide plate 31 to move, aligning the inkjet printer 33 with the printing position. The telescopic power component 34 moves the inkjet printer 33 closer to the material to be printed. Under the action of the lateral movement power component 36 and the lifting power component 31a, the inkjet printer 33 completes the printing. Finally, the lateral movement power component 36 drives the code reader 35a to align with the printing position. The code reader 35a identifies the printed code and checks the printing quality. If the code can be identified, the push plate 22 descends, the pressure plate 21 rises, and the conveyor belt 13 continues to convey the material, completing the printing. If the code cannot be identified, the camera 34a repositions the printing position and prints and reads the code again.

[0039] The automatic inkjet coding device 100 of this utility model uses a pressure plate 21 to press one end of the material to be coded, and a push plate 22 selectively passes through the worktable 11, thereby flipping the material to be coded from the worktable 11 around the bottom of the pressure plate 212 to one side of the pressure plate 21; with the cooperation of the slide plate 31 and the lifting plate 32, the inkjet printer 33 sprays code onto the material to be coded; this automatic inkjet coding device 100 prevents the inkjet printer 33 from clogging by spraying code from the front.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
