Description

Technical Field

[0001] This utility model belongs to the technical field of inkjet printing equipment, and in particular relates to a material-carrying, moving, and stable inkjet printing device. Background Technology

[0002] Currently, most inkjet printing equipment uses a single-axis or multi-axis moving platform to drive the printhead or stage for positioning. These moving platforms typically rely on a single set of guide rails or asymmetrical support structures for sliding, which has limited guiding rigidity and anti-sway capability. During continuous operation or load changes, the moving platform is prone to slight swaying or overturning moments, causing deviations in the preset relative posture between the workpiece's sprayed surface and the printhead. This leads to problems such as inaccurate coding position, distorted characters, or inconsistent coding depth, affecting the stability and consistency of coding quality.

[0003] Existing technologies attempt to address these issues by increasing guide rail dimensions, improving component machining precision, or refining drive control algorithms. However, these methods often significantly increase manufacturing costs or system complexity, and fail to fundamentally optimize the structural layout of the sliding guide to eliminate the risk of swaying. Other solutions employ an integrally reinforced frame or the addition of auxiliary leveling mechanisms; however, these structures are bulky and cumbersome to adjust, making it difficult to meet the stringent dynamic stability requirements of high-speed, high-precision inkjet printing operations. Utility Model Content

[0004] The purpose of this utility model is to provide a material-carrying, moving, and stable inkjet printing device, which aims to solve the technical problem that existing mobile platforms usually rely on a single set of guide rail pairs or asymmetrical support structures to achieve sliding, resulting in limited guiding rigidity and anti-swaying ability, leading to deviations in the preset relative posture between the workpiece being sprayed and the nozzle.

[0005] To achieve the above objectives, this utility model provides a material-carrying, mobile, stable inkjet printing device, including a machine base, a multi-axis drive mechanism, a guide mechanism, and a material carrier plate.

The first drive component is disposed on the machine base, and the second drive component is disposed at the output end of the first drive component. The number of guide mechanisms is two sets, and the two sets of guide mechanisms are respectively disposed on the first drive component and the second drive component.

[0007] Optionally, the machine base is provided with a mounting groove, the first drive component is disposed in the mounting groove, the output end of the first drive component extends to the outside of the groove of the mounting groove, and when the second drive component is disposed at the output end of the first drive component, there is a gap between the second drive component and the top surface of the machine base.

[0008] Optionally, the first drive assembly includes a first mounting plate, a first movable base, and a first linear motor.

The output end of the first linear motor is capable of reciprocating along the length direction of the first mounting plate. The guide mechanism is disposed on the first mounting plate, and the output end of the first linear motor is drivenly connected to the first movable base.

[0009] Optionally, the second drive assembly includes a second mounting plate and a second linear motor. The second mounting plate is disposed on the machine base, and the second linear motor is disposed on the second mounting plate. The output end of the second linear motor is capable of reciprocating along the length direction of the second mounting plate. The guide mechanism is disposed on the second mounting plate, and the output end of the second linear motor is drivenly connected to the second moving seat.

[0010] Optionally, the guiding mechanism includes two sets of guide shafts, which are fixedly mounted on the first mounting plate. The two sets of guide shafts extend along the length of the first mounting plate and are symmetrically distributed on both sides of the output end of the first linear motor. The bottom ends of the first movable seat are slidably connected to the corresponding guide shafts.

[0011] Optionally, the guiding mechanism includes two sets of guide shafts, which are fixedly mounted on the second mounting plate. The two sets of guide shafts extend along the length of the second mounting plate and are symmetrically distributed on both sides of the output end of the second linear motor. The bottom ends of the second movable seat are slidably connected to the corresponding guide shafts, and the material carrier plate is fixedly mounted on the end of the second movable seat facing away from the second mounting plate.

[0015] The above-mentioned technical solutions of the material-carrying moving and stable inkjet printing device provided in this utility model embodiment have at least one of the following technical effects: By setting two sets of guide mechanisms symmetrically distributed on both sides of the bottom surface of the material plate between the output end of the multi-axis drive mechanism and the material plate, when the drive mechanism is running, the two sets of guide ends act synchronously, jointly constraining and guiding the material plate to move smoothly along the preset trajectory, effectively offsetting the inherent swaying torque and torsional deformation in the unilateral or asymmetrical support structure. This structure fundamentally overcomes the technical defects of existing inkjet printing devices, which cause the material platform to shake and tilt during start-up, stop, or speed change due to insufficient rigidity of the moving platform and poor anti-disturbance ability, thus causing misalignment of the relative posture between the printing surface on the workpiece and the printhead. Therefore, without significantly increasing manufacturing costs and system complexity, it significantly improves the positional accuracy and quality consistency of the inkjet printing process.

[0026] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-3 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0027] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, such as Figures 1-3 As shown, a material-carrying, moving, and stable inkjet printing device is provided, including a machine base 100, a multi-axis drive mechanism 200, a guide mechanism 300, and a material carrier plate 400. The multi-axis drive mechanism 200 is disposed on the machine base 100; the guide mechanism 300 is disposed on the output end of the multi-axis drive mechanism 200; and the material carrier plate 400 is disposed on the guide mechanism 300. The output end of the multi-axis drive mechanism 200 is drivenly connected to the material carrier plate 400. The guide mechanism 300 has two sets of guide ends, and the guide ends of the two sets of guide mechanisms 300 are respectively fixedly connected to the two sides of the bottom surface of the material carrier plate 400.

[0031] By setting two sets of guide mechanisms 300 symmetrically distributed on both sides of the bottom surface of the carrier plate 400 between the output end of the multi-axis drive mechanism 200 and the carrier plate 400, when the drive mechanism is running, the two sets of guide ends act synchronously, jointly constraining and guiding the carrier plate 400 to move smoothly along the preset trajectory, effectively offsetting the inherent yaw moment and torsional deformation in unilateral or asymmetrical support structures. This structure fundamentally overcomes the technical defects of existing inkjet printing equipment, which cause the carrier plate to shake or tilt during start-up, shutdown, or speed change due to insufficient rigidity and poor anti-disturbance capability of the moving platform, thus causing misalignment of the relative posture between the printing surface on the workpiece and the printhead. Therefore, without significantly increasing manufacturing costs and system complexity, it significantly improves the positional accuracy and quality consistency of the inkjet printing process.

[0032] like Figures 1-3As shown, in another embodiment of this utility model, the multi-axis drive mechanism 200 includes a first drive component 210 and a second drive component 220. The drive end movement paths of the first drive component 210 and the second drive component 220 are located on a horizontal end face, and the drive end movement paths of the first drive component 210 and the second drive component 220 are designed to be perpendicular to each other. The first drive component 210 is disposed on the machine base 100, and the second drive component 220 is disposed at the output end of the first drive component 210. The number of guide mechanisms 300 is two sets, and the two sets of guide mechanisms 300 are respectively disposed on the first drive component 210 and the second drive component 220. This design decomposes the vertical motion in the horizontal plane into two independent drive components, each equipped with a dedicated guide mechanism 300. This enables precise driving and positioning of the carrier plate 400 at any position in the plane. The first drive component 210 is mainly responsible for long-stroke coarse positioning in one direction, while the second drive component 220 completes the precise positioning in the vertical direction. The two guide mechanisms 300 work together to ensure the overall rigidity under compound motion. This completely solves the positioning drift problem caused by the accumulation of errors in the serial drive chain and the coupling vibration easily generated by the single guide mechanism 300 during compound motion in existing equipment, making the coding trajectory more accurate and smooth.

[0033] like Figures 1-3 As shown, in another embodiment of this utility model, the machine base 100 is provided with a mounting groove 110, the first drive component 210 is disposed in the mounting groove 110, and the output end of the first drive component 210 extends to the outside of the groove of the mounting groove 110. When the second drive component 220 is disposed at the output end of the first drive component 210, there is a gap between the second drive component 220 and the top surface of the machine base 100. This mounting groove 110 structure embeds the main body of the first drive component 210 into the machine base 100, reducing the overall center of gravity and structural height of the equipment and improving operational stability. At the same time, the gap reserved between the second drive component 220 and the top surface of the machine base 100 effectively avoids any contact or interference between the second drive component 220 and the surface of the machine base 100 during movement, eliminating additional resistance, vibration and wear of parts caused by friction or collision. This design overcomes the defects of traditional inkjet printers, such as unsmooth movement, poor reliability and frequent maintenance, which are caused by the complete exposure or unreasonable layout of drive components, and ensures the accuracy maintenance under long-term high-speed operation.

[0034] like Figures 1-3As shown, in another embodiment of this utility model, the first driving component 210 includes a first mounting plate, a first movable seat, and a first linear motor. The first mounting plate is disposed on the machine base 100, and the first linear motor is disposed on the first mounting plate. The output end of the first linear motor can reciprocate along the length direction of the first mounting plate. The guide mechanism 300 is disposed on the first mounting plate, and the output end of the first linear motor is drivenly connected to the first movable seat. This specific configuration utilizes the first linear motor to directly drive the first movable seat, eliminating the traditional intermediate transmission links such as lead screws and belts, and realizing direct electromagnetic drive without contact. This completely eliminates backlash, elasticity, and transmission errors. The first movable seat obtains bidirectional support through a sliding connection between its bottom two ends and symmetrically arranged guide shafts 310, ensuring that the first driving component 210 has no twisting or crawling during high-speed reciprocating motion, and has extremely high motion stability. This solves the motion distortion problem caused by transmission chain errors and asymmetrical support rigidity in traditional driving methods, providing a foundation for high-precision inkjet printing.

[0035] like Figures 1-3 As shown, in another embodiment of this utility model, the second drive assembly 220 includes a second mounting plate 221, a second linear motor 222, and a second movable seat 223. The second mounting plate 221 is disposed on the machine base 100, and the second linear motor 222 is disposed on the second mounting plate 221. The output end of the second linear motor 222 can reciprocate along the length direction of the second mounting plate 221. The guide mechanism 300 is disposed on the second mounting plate 221, and the output end of the second linear motor 222 is drivenly connected to the second movable seat 223. The second drive assembly 220 also adopts a linear motor for direct drive and is combined with a double-sided symmetrical guide mechanism 300. The second linear motor 222 drives the second moving seat 223 to move precisely along the second mounting plate 221. The second moving seat 223, which carries the final material plate 400, obtains extremely high anti-overturning ability and linearity of movement through the sliding connection between its bottom two ends and the symmetrical guide shaft 310. This structural design enables the second drive assembly 220 to maintain a stable posture even when carrying a load and performing high-frequency start-stop and reversing, effectively preventing the end effector (material plate 400) from shaking and sinking due to insufficient guide support, and making up for the weakness of insufficient rigidity and precision of traditional designs on the secondary drive platform.

[0036] like Figures 1-3As shown, in another embodiment of this utility model, the guiding mechanism 300 includes two sets of guide shafts 310. The two sets of guide shafts 310 are fixedly mounted on the first mounting plate and extend along the length of the first mounting plate. The two sets of guide shafts 310 are symmetrically distributed on both sides of the output end of the first linear motor. The bottom ends of the first movable seat are slidably connected to the corresponding guide shafts 310. This symmetrical arrangement of guide shafts 310 on both sides provides balanced support and guidance for the first movable seat. The two guide shafts 310 jointly bear the bending moment and torque during operation, constraining all degrees of freedom of the first movable seat except for axial movement along the guide shafts 310, thus strictly limiting its movement trajectory. This double-track symmetrical constraint structure fundamentally eliminates the jamming, vibration, and deflection phenomena caused by uneven force on the movable seat under a single guide shaft 310 or asymmetrical layout, solving the problem of unstable movement of the movable platform affecting the consistency of inkjet printing in the prior art.

[0037] like Figures 1-3 As shown, in another embodiment of this utility model, the guiding mechanism 300 includes two sets of guide shafts 310. The two sets of guide shafts 310 are fixedly mounted on the second mounting plate 221. The two sets of guide shafts 310 extend along the length direction of the second mounting plate 221. The two sets of guide shafts 310 are symmetrically distributed on both sides of the output end of the second linear motor 222. The bottom ends of the second moving seat 223 are slidably connected to the corresponding guide shafts 310. The material carrier plate 400 is fixedly mounted on the end of the second moving seat 223 facing away from the second mounting plate 221. This structure directly fixes the material plate 400 to the second moving seat 223, which is precisely guided by the double-sided guide shafts 310. This allows the motion accuracy of the drive mechanism to be transmitted to the material plate 400 without damage through the high-rigidity guide system. The symmetrically distributed guide shafts 310 ensure that the material plate 400 always maintains a horizontal posture and moves smoothly under the drive of the second moving seat 223, without any warping or swaying. As a result, the distance and angle between the workpiece surface to be sprayed on the material plate 400 and the nozzle are constant. This design completely solves the quality defects such as blurred inkjet printing and position drift caused by poor rigidity of the end effector platform and inaccurate guidance.

[0038] like Figures 1-3As shown, in another embodiment of this utility model, the guide shaft 310 includes a base 311 and a round rod 312. The round rod 312 is fixedly mounted on the base 311. The radial cross-section of the base 311 is an isosceles trapezoid, and the radial cross-section of the round rod 312 is circular. The bottom width of the base 311 is greater than the top width. This specially shaped guide shaft 310 base 311 design, with its isosceles trapezoidal cross-section, provides a wider bottom support surface, significantly enhancing the connection rigidity and stability of the guide shaft 310 mounted on the mounting plate. It effectively resists overturning moments caused by load and movement, preventing the guide shaft 310 from loosening or deforming. The upper round rod 312 provides a precise cylindrical guide surface, ensuring smooth and high-precision sliding of the moving seat. This composite structure balances installation stability and movement accuracy, overcoming the shortcomings of traditional rectangular or circular cross-section guide rails, which are prone to deformation of the connection or decrease in guiding accuracy under heavy load or high speed.

[0039] like Figures 1-3 As shown, in another embodiment of this utility model, the base 311 is provided with a deformation compensation groove 313 along its length, and the deformation compensation groove 313 is located at the center of the base 311. This deformation compensation groove 313 serves as a stress release and deformation adjustment groove, allowing the base 311 to undergo slight elastic deformation when subjected to uneven installation pressure or internal stress caused by temperature changes. This absorbs and compensates for these stresses, preventing uncontrollable bending deformation of the base 311 as a whole, and always maintaining the upper round rod 312 within an accurate straightness range. This design solves the problem of guide straightness deviation caused by installation stress, thermal stress, and other factors in the long-stroke guide shaft 310, ensuring accuracy and reliability during long-term use.

[0040] like Figures 1-3 As shown, in another embodiment of this utility model, the coding component 500 is disposed on the top of the machine base 100 and located on one side of the multi-axis drive mechanism 200, with the output end of the coding component 500 facing the material-carrying end face of the material carrier plate 400. This arrangement fixes the coding component 500 to one side of the machine base 100, completely separating it from the moving multi-axis drive mechanism 200 and the material carrier plate 400, thus avoiding the transmission of vibration to the precision coding component 500. At the same time, the material carrier plate 400 carries the workpiece to the coding area for printing. This method of stationary printhead and moving workpiece simplifies the ink supply, power supply, and signal connection of the printing head, eliminates failures caused by fatigue and wear of moving pipelines, improves the reliability and lifespan of the coding system, and solves the problems of wire entanglement, frequent maintenance, and the impact of printhead vibration on coding quality in traditional moving printhead designs.

[0041] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
