[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0019] like Figure 1-5As shown, the rotary steel plate printing apparatus of the embodiment includes a frame 1, a rotary table 2 rotatably connected to the frame 1, a first drive assembly for driving the rotary table 2 to rotate, a plurality of printing positions 3 disposed on the rotary table 2, and a plurality of vertical pad printing machines 4 and horizontal pad printing machines 5 connected to the frame 1. The vertical pad printing machines 4 and the horizontal pad printing machines 5 are disposed on the outer periphery of the rotary table 2. Each printing position 3 includes a support platform 31 for carrying the workpiece and a second drive assembly for driving the support platform 31 to rotate. The support platform 31 is rotatably connected to the rotary table 2, and the axis of rotation of the support platform 31 is parallel to the axis of rotation of the rotary table 2.

[0020] With this design, the horizontal pad printing machine can target the four sides of the workpiece to complete the outer perimeter printing; the vertical pad printing machine can target the top of the workpiece to fill the functional gap of top printing and improve printing efficiency.

[0021] Precise motion coordination ensures seamless and consistent printing: The rotary table drives the printing station to revolve, enabling the workpiece to precisely dock with the vertical and horizontal pad printing machines on the outer periphery in sequence, achieving continuous multi-station operation and avoiding the error of repositioning after a single print. The workpiece is rotated by the support platform: Since the support platform and the rotating table are parallel to each other, the workpiece can face the horizontal pad printing machine evenly and stably when it rotates, and there will be no missing printing due to the deviation of the rotation angle. At the same time, the rotation can cooperate with the horizontal pad printing machine to cover all areas around the workpiece, completely eliminating printing dead corners.

[0022] According to one embodiment of the present invention, the vertical pad printing machine 4 includes a third base 41, a third etched steel plate 42, a third pad printing head 43, and a third driving assembly for driving the third pad printing head 43 to move back and forth between a third printing station and the third etched steel plate 42; the third base 41 is fixedly connected to the frame 1, the third etched steel plate 42 is disposed on the third base 41 and is upwardly disposed, and the third pad printing head 43 is vertically disposed.

[0023] With this design, the steel plate and the printing head are aligned to achieve precise printing on the top of the workpiece: the upward-facing third etched steel plate allows the ink to remain stably within the etched pattern, preventing ink loss due to the tilt of the steel plate; the vertically oriented third printing head can be directly aligned with the top of the workpiece, and after picking up the ink from the etched steel plate, it can be pressed down vertically to complete the top printing.

[0024] According to one embodiment of the present invention, the third driving assembly includes a third mounting base 44 fixedly connected to the third base 41, a third slide rod 45 fixedly connected to the third mounting base 44, a third screw 46 rotatably connected to the third mounting base 44, a third motor 47 driving the third screw 46 to rotate, and a third movable seat 48 slidably connected to the third slide rod 45 and threadedly connected to the third screw 46. A fifth driving assembly for driving the third pad printing head 43 to rise and fall is provided between the third movable seat 48 and the third pad printing head 43. The extension direction of the third slide rod 45 is horizontal.

[0025] According to one embodiment of the present invention, the fifth driving assembly includes a third cylinder 49 fixedly mounted on the third movable seat 48, the third pad printing head 43 being fixedly connected to the piston rod of the third cylinder 49, and the extension and retraction direction of the piston rod of the third cylinder 49 being vertically arranged.

[0026] Step 1: Move horizontally to the ink-dipping position: The third motor starts, driving the third screw connected to its output shaft to rotate; Because the third movable seat is connected to the third screw by a thread and simultaneously slides with the third slide rod, the third movable seat moves smoothly along the third slide rod toward the third etched steel plate. The third motor stops operating when the third pad printing head precisely reaches the top of the third etched steel plate.

[0027] Step 2: Complete ink application in conjunction with the fifth drive component: The piston rod of the third cylinder extends vertically downward, driving the third pad printing head, which is fixedly connected to it, to press down, so that the pad printing head contacts the ink on the surface of the third etched steel plate, thus completing the ink dipping process. After the ink is applied, the piston rod of the third cylinder retracts vertically upward, causing the ink head to leave the third etched steel plate and return to the high position required for horizontal movement.

[0028] Step 3: Move horizontally to the printing position: The third motor starts again, driving the third screw to rotate in the opposite direction; The third moving seat moves horizontally in the opposite direction along the third slide bar, simultaneously driving the third pad printing head dipped in ink to transfer; When the rotary table revolves to the position where the workpiece is located, and it reaches directly below the third printing station, the third moving seat will drive the glue head to the top of the workpiece, and the third motor will stop, completing the printing position positioning.

[0029] Step 4: Complete the top printing in conjunction with the fifth drive component: The piston rod of the third cylinder extends vertically downwards again, driving the third pad printing head to press down to the top surface of the workpiece, transferring the ink pattern onto the workpiece and completing the top printing. After printing is completed, the piston rod of the third cylinder retracts vertically upward, causing the printing head to detach from the workpiece and return to its high position.

[0030] Step 5: Reset and prepare for the next cycle: The third motor drives the third screw to rotate in the opposite direction again, and the third moving seat returns to its initial standby position close to the third etched steel plate, waiting for the next cycle.

[0031] According to one embodiment of the present invention, the horizontal pad printing machine 5 includes a fourth base 51, a fourth etched steel plate 52, a fourth pad printing head 53, and a fourth drive assembly for driving the fourth pad printing head 53 to move back and forth between the fourth printing station and the fourth etched steel plate 52; the fourth base 51 is fixedly connected to the frame 1, the fourth etched steel plate 52 is disposed on the fourth base 51 and faces away from the rotary table 2, and the fourth pad printing head 53 is oriented horizontally.

[0032] With this design, the printing head is horizontally oriented, adapting to the printing needs around the workpiece: the workpiece is placed on the carrier platform of the rotary table, and the horizontally oriented fourth pad printing head can be directly aligned with the side of the workpiece. Without adjusting the angle of the printing head, it can directly contact the outer periphery of the workpiece through the horizontal extension and retraction of the printing head, and complete the printing operation around the workpiece in conjunction with the rotation of the workpiece.

[0033] According to one embodiment of the present invention, the fourth driving assembly includes a fourth mounting base 54 fixedly connected to the fourth base 51, a fourth slide rod 55 fixedly connected to the fourth mounting base 54, a fourth screw 56 rotatably connected to the fourth mounting base 54, a fourth motor 57 driving the fourth screw 56 to rotate, and a fourth moving base 58 slidably connected to the fourth slide rod 55 and threadedly connected to the fourth screw 56. A sixth driving assembly for driving the fourth pad printing head 53 to move horizontally is provided between the fourth moving base 58 and the fourth pad printing head 53. The extension direction of the fourth slide rod 55 is vertically arranged.

[0034] According to one embodiment of the present invention, the sixth driving assembly includes a fourth cylinder 59 fixedly mounted on the fourth movable seat 58, the fourth pad printing head 53 being fixedly connected to the piston rod of the fourth cylinder 59, and the extension and retraction direction of the piston rod of the fourth cylinder 59 being horizontal.

[0035] Step 1: The fourth drive component drives the fourth moving seat to move vertically to the ink-dipping height. The fourth motor starts, and its output shaft drives the fourth screw connected to it to rotate. Since the fourth movable seat is simultaneously slidably connected to the fourth slide rod and threadedly connected to the fourth screw, the rotational motion of the fourth screw is converted into the vertical linear motion of the fourth movable seat. The fourth moving seat rises and falls vertically along the fourth slide bar until the fourth cylinder fixed on it drives the fourth pad printing head to precisely align with the height of the printed pattern on the fourth etched steel plate. The fourth motor then stops running, and the fourth moving seat achieves vertical positioning.

[0036] The second step involves the sixth drive component working together to complete the horizontal ink application: The piston rod of the fourth cylinder extends horizontally, driving the fourth pad printing head, which is fixedly connected to it, to move horizontally until the pad print head adheres to the surface of the fourth etched steel plate and picks up the ink pattern on the steel plate. After the ink is applied, the piston rod of the fourth cylinder retracts horizontally, causing the fourth pad printing head to detach from the fourth etched steel plate and return to its initial horizontal position.

[0037] Step 3: The fourth drive component drives the fourth moving seat to move vertically to the printing height. The fourth motor starts again, driving the fourth screw to rotate in the opposite direction; The fourth moving seat rises and falls vertically along the fourth slide bar, simultaneously driving the fourth pad printing head, which is dipped in ink, to move until it is aligned with the side of the workpiece at the fourth printing station on the outer periphery of the rotary table. The fourth motor then stops, completing the printing height positioning.

[0038] Step 4: The sixth driving component works together to complete the horizontal printing. The piston rod of the fourth cylinder extends horizontally again, causing the fourth pad printing head to press horizontally against the side of the workpiece; At this time, the support platform drives the workpiece to rotate, and the ink head can continuously and evenly transfer the ink pattern to the four sides of the workpiece to complete the horizontal peripheral printing. After printing is completed, the piston rod of the fourth cylinder retracts horizontally, causing the fourth pad printing head to detach from the workpiece, thus preventing the workpiece from scraping the pad printing head when it rotates.

[0039] Step 6: Reset and standby, preparing for the next cycle: The fourth motor drives the fourth screw to rotate in the opposite direction again, and the fourth moving seat moves vertically along the fourth slide bar, returning to the initial ink-dipping height standby position.

[0040] According to one embodiment of the present invention, the first drive assembly includes a first motor 11 fixedly connected to the frame 1, and a first reducer 12 is provided between the output shaft of the first motor 11 and the rotary table 2.

[0041] The core function of the first reducer is to reduce the speed and increase the torque: on the one hand, it converts the high speed of the first motor into a low speed that is suitable for the rotary table, ensuring that the workpiece can stay accurately at each printing station; on the other hand, by increasing the torque, it provides sufficient driving force for the rotary table, so that even if it is carrying multiple workpiece loads, it can maintain smooth rotation and avoid jamming or speed fluctuations.

[0042] According to one embodiment of the present invention, the second drive assembly includes a second motor 21 fixedly connected to the rotary table 2, and a second reducer 22 is provided between the output shaft of the second motor 21 and the support platform 31.

[0043] The core function of the second reducer is to reduce the speed and increase the torque: on the one hand, it converts the high speed of the second motor into a low speed that is suitable for the workpiece, ensuring that the horizontal pad printing head has enough time to complete printing on one side; on the other hand, by increasing the torque, it provides sufficient driving force to the carrier platform, so that even if it carries workpieces of different weights, it can maintain smooth rotation and avoid jamming or sudden changes in speed.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
