Detailed Implementation

[0030] To enhance understanding of this utility model, it will be further described in detail below with reference to embodiments and accompanying drawings. This utility model can be implemented in the following ways:

[0031] Reference Figure 1-5 A fully automatic sheet metal inkjet printer includes a base 1 positioned on the side of a conveyor line, a movable inkjet printer stand 2 with an opening facing the conveyor line and slidably mounted on the base 1, and a multi-head inkjet printer 3 movably mounted within the movable inkjet printer stand 2. The movable inkjet printer stand 2 has an opening on the side facing the conveyor line, ensuring no obstruction between the multi-head inkjet printer 3 and the sheet metal on the conveyor line. The multi-head inkjet printer 3 is slidably mounted on a lifting connecting seat 4, which is equipped with a front-to-back drive mechanism 5 for driving the multi-head inkjet printer 3 closer to or further away from the conveyor line. The movable inkjet printer stand 2 contains a lifting drive mechanism 6 for driving the lifting connecting seat 4 up and down. The base 1 has a transverse drive mechanism 7 for controlling the reciprocating movement of the movable inkjet printer stand 2 along the base 1. This fully automatic sheet metal inkjet printer utilizes the front-to-back drive mechanism 5, the lifting drive mechanism 6, and the transverse drive mechanism 7 to drive the multi-head inkjet printer 3 in its forward / backward, up / down, and left / right positions, respectively, enabling it to meet the inkjet printing requirements of sheet metal with different stacking heights and thicknesses, thus having a wide range of applications.

[0032] Specifically, the multi-head inkjet printer 3 is equipped with multiple ink cartridges 31 arranged in a stepped manner. The printheads 32 of all the ink cartridges 31 face the conveyor line. The number of ink cartridges 31 can be increased or decreased according to actual needs. In this embodiment, there are five ink cartridges 31, allowing it to complete the inkjet printing of five boards in one round trip, resulting in high inkjet printing efficiency. The multi-head inkjet printer 3 is electrically connected to a central controller, and the printing delay time of each printhead 32 can be set using a program. In this embodiment, the printing delay time of the printheads 32 increases sequentially from top to bottom, meaning the printhead 32 at the highest position prints first, and the printhead 32 at the lowest position prints last, thus ensuring that the printing positions of the five boards are consistent.

[0033] To fix the position of the printhead 32, a detachable printhead guard plate 33 is provided at the free end of the printhead 32. The ink cartridge 31 is detachably mounted on the printhead guard plate 33. In this embodiment, the ink cartridge 31 is fixedly mounted on the printhead guard plate 33 with screws. In this embodiment, the printhead guard plate 33 is provided with five printhead openings 331 for the printhead 32 to be inserted, which can fix the position of the printhead 32 and prevent the printhead 32 from being misaligned during the movement of the inkjet printer, thereby improving the accuracy of the printing. In addition, when the thickness of the wood board changes, the distance between the printheads 32 can be adjusted by replacing the printhead guard plate 33 with the corresponding model, which can meet the printing needs of boards of different thicknesses, and has a wide range of applications.

[0034] Since the distance between the printhead 32 of the inkjet printer and the board material affects the quality of the inkjet printing, a forward extension detector 8 is provided on the side of the multi-head inkjet printer 3 to ensure that the inkjet printer maintains the optimal distance from the board material and prevents the distance from being too close or too far. The forward extension detector 8 is a travel limiter. When the inkjet printer approaches the board material under the drive of the front and rear drive mechanism 5, when the forward extension detector 8 detects that the distance between the printhead 32 and the board material is the optimal distance set value, it feeds back a signal to the front and rear drive mechanism 5, controlling the multi-head inkjet printer 3 to stop advancing, thereby ensuring the quality of the inkjet printing.

[0035] To ensure that each printhead 32 corresponds to one sheet material, a lifting alignment detector 9 is provided on the side of the multi-head inkjet printer 3. The lifting alignment detector 9 is an infrared detection device for lifting balance alignment. When the multi-head inkjet printer 3 is raised and lowered into position under the drive of the lifting drive mechanism 6, the lifting alignment detector 9 will detect whether its printhead 32 is exactly aligned with the center position of the area to be printed on the sheet material, ensuring that each printhead 32 corresponds to one sheet material and preventing the printing position from fluctuating or even printing between two sheets material.

[0036] To allow the multi-head inkjet printer 3 to move closer to or further away from the conveyor line, the front and rear drive mechanism 5 includes front and rear guide rails 51 mounted on the lifting connecting seat 4, front and rear sliders 52 mounted at the bottom of the multi-head inkjet printer 3, and a front and rear drive source 53 that controls the reciprocating movement of the sliders 52 on the guide rails 51. The front and rear drive source 53 is a front and rear telescopic stepper motor. The telescopic stepper motor converts electrical pulse signals into corresponding linear displacements; that is, for each input pulse signal, the rotor moves forward one step. Its output linear displacement is proportional to the number of input pulses, and its rotational speed is proportional to the pulse frequency. One end of the slider 52 is slidably connected to the guide rails 51, and the other end is connected to the drive source 53. The drive source 53 drives the sliders 52 to move the multi-head inkjet printer 3 reciprocally on the guide rails 51, thereby allowing the multi-head inkjet printer 3 to move closer to or further away from the sheet metal on the conveyor line.

[0037] To achieve the lifting function of the multi-head inkjet printer 3, the lifting drive mechanism 6 includes a lifting guide rail 61 installed within the mobile inkjet printer stand 2, a lifting slider 62 connected to the lifting connecting seat 4, a lead screw 63 connected to the lifting slider 62, and a lifting drive source 64 that drives the lead screw 63 to rotate, thereby causing the lifting slider 62 to move up and down along the lifting guide rail 61. The lifting drive source 64 is a lifting servo motor. The lifting slider 62 and the lead screw 63 are connected by a ball screw, and during rotation, the lead screw 63 converts the rotational motion of the lead screw into the linear motion of the lifting slider 62. The lifting servo motor drives the lead screw 63 to rotate, causing the lifting slider 62 to move up and down, which in turn drives the lifting connecting seat 4, thereby causing the multi-head inkjet printer 3 to move up and down.

[0038] Because the number of characters to be printed on the board is relatively large, a multi-head inkjet printer 3 needs to move laterally to complete the task. To achieve the lateral movement function of the multi-head inkjet printer 3, the lateral drive mechanism 7 includes a lateral guide rail 71 mounted on the base 1, a lateral slider 72 mounted at the bottom of the movable inkjet printer stand 2, and a lateral drive source 73 that drives the movable inkjet printer stand 2 to reciprocate along the lateral guide rail 71. Specifically, the lateral drive source 73 includes a belt 731 connected to the back of the movable inkjet printer stand 2 and a lateral servo motor 732 that drives the belt 731 to rotate. The lateral servo motor 732 drives the movable inkjet printer stand 2 to reciprocate along the lateral guide rail 71 by rotating the belt 731. To ensure smoother lateral movement of the movable inkjet printer stand 2, two lateral guide rails 71 are symmetrically arranged on the base 1. To prevent the transverse guide rail 71 from tilting or tipping over during lateral movement, the base 1 has a back plate 11 on the side away from the conveyor line. An auxiliary guide rail 74 is mounted on the back plate 11, and an auxiliary connecting block 75, which is slidably connected to the auxiliary guide rail 74, is located on the back of the mobile inkjet printer stand 2. This design ensures that the back of the mobile inkjet printer stand 2 always rests against the auxiliary guide rail 74 during lateral movement, thus maintaining a vertical position and further improving the accuracy of the inkjet printing.

[0039] Working Principle: Stacked boards are conveyed to the side of the fully automatic board marking machine via a conveyor line. A board positioning sensor is installed on the conveyor line. When the board positioning sensor detects that the board has reached the designated position, it sends a signal to the central controller. The central controller then stops the conveyor line and starts the fully automatic board marking machine. The front and rear drive source 53 drives the front and rear sliders 52, causing the multi-head marking machine 3 to move along the front and rear guide rails 51 towards the board. When the forward positioning detector 8 detects that the distance between the printhead 32 and the board is the optimal distance set value, it sends a signal to the front and rear drive mechanism 5, causing the multi-head marking machine 3 to stop moving forward. Then, the lifting servo motor drives the lead screw 63 to rotate, causing the multi-head marking machine 3 on the lifting connecting seat 4 to descend until the highest printhead 32 is aligned with the highest board. At this time, the lifting alignment detector 9 checks whether the printhead 32 is exactly aligned with the center position of the board to be marked, ensuring that each printhead 32 corresponds to one board. Next, the horizontal servo motor 732 drives the movable inkjet printer stand 2 to move along the horizontal guide rail 71 towards the horizontal servo motor 732 via the drive belt 731. At the same time, the multi-head inkjet printer 3 begins printing, with the highest printhead 32 printing first and the lowest printhead 32 printing last. After the printing operation of the 1st to 5th boards is completed, the horizontal servo motor 732 drives the movable inkjet printer stand 2 to reset, and the lifting servo motor drives the multi-head inkjet printer 3 to descend to the 6th board. Then, the horizontal drive mechanism 7 drives the multi-head inkjet printer 3 to complete the printing operation of the 6th to 10th boards and then resets. The above steps are repeated until the printing operation of the bottom board is completed. Then, the lifting servo motor drives the multi-head inkjet printer 3 to rise to the highest position, waiting for the next stack of boards.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
