Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please refer to Figure 1 This utility model provides an inkjet printer for 3D lenticular printing, including a frame 1, a printing stage 2, a Y-axis drive device for the printing stage 3, a print head 4, an XZ dual-axis moving drive device 5, and a print head cleaning device 6, etc. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

One end of the Y-axis lead screw 33 is rotatably installed on the bottom of the worktable 11. The bottom of the suction table mounting base 31 is fixedly connected to the Y-axis nut seat 34 sleeved on the Y-axis lead screw 33.

[0031] like Figure 3 As shown, the printer head 4 may include a print head support 41, an inkjet head 42 for printing ink onto the surface of the grating substrate to be coated, and a UV irradiation device 43 for irradiating and curing the ink on the surface of the grating substrate. The inkjet head 42 is provided in several groups and is installed at intervals inside the print head support 41. Each group of inkjet heads 42 is provided with several nozzles 44 protruding from the bottom of the print head support 41. There are two UV irradiation devices 43 and they are installed on the two sides of the print head 4 respectively. The print head cleaning device 6 is fixedly installed at the lower part of one end of the X-axis of the XZ dual-axis moving drive device 5 and is located outside the worktable 11.

[0032] Each inkjet head 42 precisely sprays ink onto the surface of the grating substrate through the nozzle 44 to form a layered structure of 3D image. Some inkjet heads 42 can squeeze ink by heating bubbles (thermal foaming technology) or push ink droplets by vibrating piezoelectric crystals (micro piezoelectric technology).

[0035] The printhead cleaning device 6 can raise the ink-absorbing pad 61 to contact the nozzle 44 via the lifting platform 62 when the X-axis end of the XZ dual-axis moving drive device 5 is reset on the printer table 4, thereby absorbing residual ink, completing the printhead cleaning operation, and improving the service life of the printhead. In this embodiment, the ink-absorbing pad 63 can be a commercially available ink-absorbing pad with an internal ink pump structure. In addition, the lifting platform 62 can also be a commercially available automatic lifting platform with a manual lifting knob.

The output part of the Z-axis motor 511 is connected to the middle part of the Z-axis lead screw 512 and drives it to rotate. The two ends of the Z-axis lead screw are rotatably set on the two Z-axis guide rail fixing plates 516 and fixedly connected to the two outer Z-axis lifting gears 513. The Z-axis linear guide rail 515 is fixedly connected to the Z-axis guide rail fixing plate 516 along the length direction of the Z-axis guide rail fixing plate 516.

[0040] like Figures 8 to 10 As shown, the X-axis moving module may include an X-axis guide beam 521, a guide beam support plate 522, a support plate slider 523, a Z-axis lifting rack 514, an X-axis motor 524, an X-axis drive wheel 525, an X-axis driven wheel 526, a first X-axis transmission belt 527, a second X-axis transmission belt 528, an X-axis linear guide rail 529, an X-axis slider 530, and a transmission belt fixing seat 54. Two guide beam support plates 522 are provided and respectively installed at the bottom of the X-axis guide beam 521. The X-axis guide beam 521 is slidably connected to the Z-axis linear guide rail 515 through the support plate slider 523 fixedly connected to the guide beam support plate 522. The Z-axis lifting rack 514 is fixed to the guide rail. The X-axis motor 524 is mounted on one end of the X-axis guide beam 521 and meshes with the Z-axis lifting gear 513. The X-axis driven wheel 526 is mounted on both ends of the X-axis guide beam 521. The X-axis driving wheel 525 on the output shaft of the X-axis motor 524 is connected to the X-axis driven wheel 526 on the same side through the first X-axis transmission belt 527. The second X-axis transmission belt 528 is fitted between the two X-axis driven wheels 526.

The back of the head bracket 41 is connected to the second X-axis transmission belt 528 through the transmission belt fixing seat 54.

[0041] Furthermore, it may also include a grating ruler 71, a grating mounting base 72, and a grating sensor 73. The grating ruler 71 is connected to the upper part of the X-axis guide beam 521 by the grating mounting base 72, which is fixedly installed on both sides of the X-axis guide beam 521. The grating sensor 72 is fixedly connected to the back of the printer head 4 and is installed in conjunction with the grating ruler 71.

[0042] The working principle of this embodiment is as follows:

[0043] During operation, the printing suction table moves along the Y-axis via the suction table's Y-axis drive device, precisely positioning the grating substrate below the print head. The bottom suction fan adheres to and fixes the substrate through suction holes. The XZ dual-axis movement drive device moves the print head along the X and Z axes, achieving printing area coverage. Multiple inkjet heads within the print head spray ink onto the substrate surface in 3D layered spray patterns through nozzles. A grating ruler and grating sensor work together to provide real-time feedback, ensuring precise positioning of the print head movement and achieving high-precision 3D grating printing. Simultaneously, UV irradiation devices on both sides emit ultraviolet light to cure the ink, completing the printing process. After printing, the print head returns to one end along the X-axis. The print head cleaning device's lifting platform raises the ink-absorbing pad, which contacts the bottom of the nozzles to absorb residual ink for cleaning.

[0044] In summary, this invention enables precise positioning of the lenticular substrate in the Y-axis direction by driving the printing suction table via the Y-axis suction device, and precise positioning of the print head in the X and Z axes by the XZ dual-axis moving drive device. Multiple inkjet heads, in conjunction with a UV irradiation device, achieve instant printing and curing. The printhead cleaning device can promptly clean residual ink from the nozzles. It features fast printing speed, effectively improves printing accuracy and efficiency, ensures printing quality and stability, and can meet the needs of 3D lenticular printing.

[0045] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
