Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology for seat rails, and more particularly to a surface inkjet printing device for aircraft seat rails and its method of use. Background Technology

[0002] As a key load-bearing component of aviation equipment, aircraft seat rails require surface marking during the production and processing to achieve product traceability, specification identification, and quality control. Currently, the industry mostly uses ordinary laser marking equipment to mark the rails.

[0003] Currently, in traditional inkjet printing equipment, during operation, metallic fumes and debris generated by laser ablation easily adhere to the surface of the guide rail and the tip of the laser printhead. This not only causes quality defects such as blurred, incomplete, and poorly adhered markings, but also affects the stability of laser output and the lifespan of the printhead. Although some equipment is equipped with a simple blowing structure, most of them are fixed blowing methods with limited blowing range and insufficient airflow velocity. They cannot achieve adaptive cleaning with the marking stroke and lack dustproof protection structures, making them susceptible to secondary pollution from external dust. These systems are ill-suited to the stringent requirements of aircraft seat guide rails for marking clarity, completeness, and production cleanliness. Therefore, there is an urgent need for a surface inkjet printing device for aircraft seat guide rails and its application method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a surface marking device and its application method for aircraft seat guide rails. Its advantages include: enabling rapid and accurate positioning and convenient assembly / disassembly of aircraft seat guide rails, effectively avoiding clamping interference and marking offset, and improving positioning accuracy and production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A surface coding device for aircraft seat guide rails includes an electrical control box and workbenches disposed on both sides of the electrical control box. A fixing rod is fixedly connected to the top outer wall of the electrical control box, and a positioning seat for coding and positioning the guide rail body is fixedly connected to the top of the fixing rod. A laser marking device for marking the guide rail body is installed above the electrical control box, and a wire is fixedly connected to the top of the laser marking device. The top of the electrical control box is equipped with a displacement component for adjusting the position of the laser printer and a purge component for improving the quality of the inkjet printing.

[0006] The above technical solutions enable the electric control box as the control core, which, together with the positioning seat, enables the rapid and accurate clamping and positioning of the guide rail body. The displacement component allows for flexible adjustment of the laser marking position, while the blowing component cleans the marking area in real time. By coordinating positioning, adjustment, and cleaning, the system ensures accurate, clear, and stable marking on the surface of the aviation seat guide rail, effectively improving marking efficiency and product quality.

[0007] Preferably, a vertical rod is fixedly connected to the top outer wall of the workbench, and a horizontal rod and a longitudinal beam are fixedly connected to the outer walls on both sides of the vertical rod, respectively. A transparent plate for preventing dust from contaminating the surface of the guide rail body is fixedly connected to one side of the vertical rod.

[0008] The above technical solutions effectively block external dust, debris, and other contaminants from contacting the guide rail body, preventing secondary contamination of the coding area, providing a clean working environment for high-precision coding, and improving the quality and stability of marking.

[0009] Preferably, the displacement assembly includes a vertical frame fixedly connected to the outer wall of the top of the fixed rod, a reinforcing rod fixedly connected to one side of the outer wall of the vertical frame, an adjusting frame fixedly connected to one side of the reinforcing rod, a motor fixedly connected to one side of the outer wall of the adjusting frame, a threaded screw fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the outer circumference of the threaded screw, a sliding rod fixedly connected to one side of the outer wall of the threaded sleeve, a mounting plate fixedly connected to one end of the sliding rod, and the laser marking device fixedly connected to the mounting plate.

[0010] The above technical solution enables the screw to rotate via a motor, thereby driving the threaded sleeve, mounting plate, and laser marking device to achieve smooth linear displacement and precise adjustment of the marking position. This meets the marking and processing needs of different specifications of aviation seat guide rails, improving the equipment's versatility and adjustment accuracy.

[0011] Preferably, a sliding groove is provided on one outer wall of the adjustment frame, and the sliding rod is slidably connected to the sliding groove.

[0012] The above technical solutions enable the slide bar to slide stably along the slide groove, restrict the circumferential rotation of the threaded sleeve, and ensure that the laser marking device does not shake or deviate during movement, thereby further improving the accuracy of the marking position and the reliability of the operation.

[0013] Preferably, the top outer wall of the positioning seat is provided with a slot, the slot being adapted to the specifications of the guide rail body, and the top of the positioning seat is provided with a square groove, the square groove being connected to the slot, the depth of the square groove being greater than the depth of the slot.

[0014] Through the above technical solutions: the slot can accurately limit and clamp the guide rail body, ensuring uniform coding position, and the square slot can avoid the guide rail protrusion structure, avoiding clamping interference. At the same time, it facilitates quick disassembly and replacement of the guide rail, taking into account both positioning accuracy and production efficiency.

[0015] Preferably, the purging assembly includes an extension plate fixedly connected to the outer wall of one side of the mounting plate, a rotating tube rotatably connected to the top of the extension plate, an air guide tube inserted into the top of the rotating tube, a flexible hose fixedly connected to the end of the air guide tube away from the rotating tube, a diverter tube fixedly connected to the end of the rotating tube away from the air guide tube, and an arc-shaped tube fixedly connected to the outer circumferential wall of the diverter tube, one end of the arc-shaped tube being located on one side of the bottom of the laser marking device.

[0016] The above technical solution enables the blowing component to move synchronously with the laser marking machine. The airflow continuously blows through the arc tube to sweep the marking area and the end of the printhead, promptly removing the smoke and dust generated by laser burning and preventing smoke and dust from adhering and affecting the light output effect and marking clarity.

[0017] Preferably, a bend is fixedly connected to the outer circumferential wall of the diverter, and one end of the bend is provided with a speed-increasing component for increasing the airflow purging speed.

[0018] The above technical solutions can increase the speed of the blowing airflow by using speed-increasing components, enhance the cleaning power, efficiently remove floating dust and debris from the guide rail surface, further improve the cleanliness of the substrate before inkjet printing, and ensure the adhesion and integrity of the markings.

[0019] Preferably, the speed-increasing component includes an expansion portion fixedly connected to one end of the bend, a narrow tube portion fixedly connected to one end of the expansion portion, and a contraction portion fixedly connected to the end of the narrow tube portion away from the expansion portion, wherein the expansion portion, the narrow tube portion, and the contraction portion are integrally formed.

[0020] The above technical solution utilizes a Venturi structure formed by an expansion section, a narrow tube section, and a contraction section to significantly improve the airflow ejection speed and impact force, achieving efficient and powerful purging. Furthermore, the one-piece molded structure provides good sealing, stable airflow, and strong durability.

[0021] Preferably, a rectangular groove is formed on one side of the outer wall of the adjusting frame, and teeth are fixedly connected inside the rectangular groove. The teeth mesh with a gear disk, and the gear disk is fixedly connected to the outer circumferential wall of the rotating tube.

[0022] The above technical solution enables the gear disk to mesh and rotate with the teeth as the laser printer moves, thereby driving the rotating tube, the diverter tube, and the arc tube to rotate synchronously, achieving all-round, dead-angle-free cleaning of the coding area, resulting in more thorough cleaning and more stable coding quality.

[0023] A surface marking device for aircraft seat guide rails, applied to the surface marking device for aircraft seat guide rails described in the above embodiments, includes the following steps: S1: Insert the aircraft seat rail body into the slot of the positioning seat to complete the positioning and clamping, ensuring that the rail is placed stably; S2: Start the electrical control box, adjust the laser printer to the appropriate printing position through the displacement component, and at the same time turn on the external air supply system; S3: Start the laser marking machine to perform marking operations. The blowing and cleaning component rotates accordingly and simultaneously blows and cleans the marking area. S4: After the inkjet printing is completed, turn off the equipment, remove the guide rail body, and complete the single inkjet printing process.

[0024] The beneficial effects of this invention are as follows: A surface marking device for aircraft seat guide rails and its usage method are disclosed. The device achieves rapid and accurate positioning of the aircraft seat guide rails through the cooperation of a positioning seat, a slot, and a square groove. The slot is compatible with the specifications of the guide rail body to ensure consistent marking position. The square groove is deeper than the slot, which avoids the protruding structure of the guide rail and avoids positioning interference. It also facilitates quick disassembly and replacement of the guide rail after marking, significantly improving loading and unloading efficiency. At the same time, the stable positioning method can reduce the problems of marking skew and defects caused by guide rail offset. It is suitable for batch processing of multiple models of aircraft seat guide rails, effectively improving production efficiency and product qualification rate.

[0025] A surface marking device for aircraft seat guide rails and its usage method are disclosed. Through the linkage design of displacement component and blowing component, the marking position can be precisely adjusted and synchronously cleaned by blowing. The motor drives the threaded screw to move the threaded sleeve, mounting plate and laser marking machine smoothly along the slide. The device is flexible in adjustment and has high positioning accuracy, which can meet the processing needs of different lengths and marking positions. The blowing component moves synchronously with the laser marking machine. The arc tube continuously blows the marking head to avoid dust adhesion and uneven laser output. In conjunction with the gear disk and tooth meshing to drive the blowing structure to rotate, the marking area is fully covered and cleaned, ensuring clear markings and neat edges from the source.

[0026] A surface coding device for aircraft seat guide rails and its application method are disclosed. The device further improves coding quality and operational stability through the synergy of a speed-increasing component and a transparent plate. The speed-increasing component, which is integrally formed by an expansion section, a narrow tube section, and a contraction section at the end of the curved tube, utilizes the Venturi effect to significantly increase airflow velocity and purging impact force, effectively removing floating dust, debris, and oxide layers from the guide rail surface and improving marking adhesion. At the same time, the transparent plate on one side of the worktable can prevent external dust from entering the coding area, reducing secondary pollution. The entire device has a compact structure and a high degree of automation. While improving coding quality and processing efficiency, it reduces manual intervention and equipment failure rate, making it suitable for the high-precision and high-reliability coding requirements of the aviation field.

[0033] Reference Figures 1-7 A surface coding device for aircraft seat rails includes an electrical control box 1 and worktables 12 disposed on both sides of the electrical control box 1. A fixing rod 9 is fixedly connected to the top outer wall of the electrical control box 1, and a positioning seat 10 for coding and positioning the rail body 29 is fixedly connected to the top of the fixing rod 9. A laser printer 13 for marking the guide rail body 29 is installed above the electrical control box 1, and a wire 7 is fixedly connected to the top of the laser printer 13. The top of the electrical control box 1 is equipped with a displacement component for adjusting the position of the laser coder 13 and a cleaning component for improving the coding quality. With the electrical control box 1 as the control core, the guide rail body 29 can be quickly and accurately clamped and positioned in conjunction with the positioning seat 10. The displacement component is used to flexibly adjust the working position of the laser coder 13, while the cleaning component cleans the coding area in real time. The positioning, adjustment and cleaning aspects work together to ensure that the coding on the surface of the aviation seat guide rail is accurate, clear and stable, effectively improving coding efficiency and finished product quality.

[0034] Furthermore, a vertical rod 2 is fixedly connected to the top outer wall of the workbench 12, and a horizontal rod 3 and a longitudinal beam 6 are fixedly connected to the outer walls on both sides of the vertical rod 2, respectively. A transparent plate 4 is fixedly connected to one side of the vertical rod 2 to prevent dust from contaminating the surface of the guide rail body 29. The transparent plate 4 can effectively block external dust, debris and other pollutants from contacting the guide rail body 29, avoid secondary contamination of the coding area, provide a clean working environment for high-precision coding, and improve the quality and stability of marking.

[0035] Furthermore, the displacement assembly includes a vertical frame 33 fixedly connected to the top outer wall of the fixed rod 9. A reinforcing rod is fixedly connected to one side of the outer wall of the vertical frame 33, and an adjusting frame 11 is fixedly connected to one side of the reinforcing rod. A motor 32 is fixedly connected to one side of the outer wall of the adjusting frame 11. A threaded screw 16 is fixedly connected to the output end of the motor 32. A threaded sleeve 18 is threadedly connected to the outer circumference of the threaded screw 16. A sliding rod is fixedly connected to one side of the outer wall of the threaded sleeve 18. A mounting plate 17 is fixedly connected to one end of the sliding rod. The laser marking device 13 is fixedly connected to the mounting plate 17. The motor 32 can drive the threaded screw 16 to rotate, thereby driving the threaded sleeve 18, the mounting plate 17, and the laser marking device 13 to achieve smooth linear displacement and accurately adjust the marking position. This meets the marking processing needs of different specifications of aviation seat guide rails and improves the equipment's versatility and adjustment accuracy.

[0036] Furthermore, a groove 34 is provided on one outer wall of the adjusting frame 11, and the slide rod is slidably connected to the groove 34, so that the slide rod slides stably along the groove 34, restricting the circumferential rotation of the threaded sleeve 18, ensuring that the laser marking device 13 does not shake or deviate during the movement process, and further improving the accuracy of the marking position and the reliability of the operation.

[0037] Furthermore, the top outer wall of the positioning seat 10 is provided with a slot 30, which is compatible with the specifications of the guide rail body 29. The top of the positioning seat 10 is provided with a square groove 31, which is connected to the slot 30. The depth of the square groove 31 is greater than the depth of the slot 30. The slot 30 can accurately limit and clamp the guide rail body 29 to ensure uniform coding position. The square groove 31 can avoid the protruding structure of the guide rail to avoid clamping interference. At the same time, it facilitates quick disassembly and replacement of the guide rail, taking into account both positioning accuracy and production efficiency.

[0038] Furthermore, the blowing assembly includes an extension plate 14 fixedly connected to the outer wall of one side of the mounting plate 17. A rotating tube 22 is rotatably connected to the top of the extension plate 14. An air guide tube 21 is inserted into the top of the rotating tube 22. A flexible hose 8 is fixedly connected to the end of the air guide tube 21 away from the rotating tube 22. A diverter tube 24 is fixedly connected to the end of the rotating tube 22 away from the air guide tube 21. An arc-shaped tube 23 is fixedly connected to the outer circumference of the diverter tube 24. One end of the arc-shaped tube 23 is located on one side of the bottom of the laser marking device 13, which enables the blowing assembly to move synchronously with the laser marking device 13. The airflow continuously blows through the arc-shaped tube 23 to clean the marking area and the end of the nozzle, promptly removing the smoke and dust generated by laser burning, and preventing the smoke and dust from adhering and affecting the light output effect and marking clarity.

[0039] Furthermore, a bend 25 is fixedly connected to the outer circumferential wall of the diversion pipe 24. One end of the bend 25 is equipped with a speed-increasing component to increase the airflow purging speed. The speed-increasing component can be used to increase the purging airflow speed, enhance the cleaning power, and efficiently remove floating dust and debris from the guide rail surface, further improving the cleanliness of the substrate before inkjet printing and ensuring the adhesion and integrity of the marking.

[0040] Furthermore, the speed-increasing component includes an expansion portion 26 fixedly connected to one end of the bend 25, a narrow tube portion 27 fixedly connected to one end of the expansion portion 26, and a contraction portion 28 fixedly connected to the end of the narrow tube portion 27 away from the expansion portion 26. The expansion portion 26, the narrow tube portion 27, and the contraction portion 28 are integrally formed. By utilizing the Venturi structure formed by the expansion portion 26, the narrow tube portion 27, and the contraction portion 28, the airflow ejection speed and impact force can be significantly improved, achieving efficient and powerful purging. Moreover, the integrally formed structure has good sealing performance, stable airflow, and strong durability.

[0041] Furthermore, a rectangular groove 15 is provided on one outer wall of the adjusting frame 11. A tooth 20 is fixedly connected inside the rectangular groove 15. The tooth 20 meshes with a gear disk 19. The gear disk 19 is fixedly connected to the outer circumference of the rotating tube 22. When the gear disk 19 moves with the laser printer 13, it meshes with the tooth 20 and rotates, thereby driving the rotating tube 22, the diverter tube 24 and the arc tube 23 to rotate synchronously, so as to achieve all-round cleaning of the coding area without dead angles, more thorough cleaning and more stable coding quality.

[0042] A surface marking device for aircraft seat guide rails, applied to the surface marking device for aircraft seat guide rails described in the above embodiments, includes the following steps: Step 1: Insert the aircraft seat rail body 29 into the slot 30 of the positioning seat 10 to complete the positioning and clamping, and ensure that the rail is placed firmly. Step 2: Start the electrical control box 1, adjust the laser marking machine 13 to the appropriate marking position through the displacement component, and at the same time turn on the external air supply system; Step 3: Start the laser marking machine 13 to perform marking operations. The cleaning component rotates accordingly and simultaneously cleans the marking area. Step 4: After the inkjet printing is completed, turn off the equipment, remove the guide rail body 29, and the single inkjet printing process is completed.

[0043] Working principle: During operation, the operator first inserts the aircraft seat guide rail body 29 into the slot 30 of the positioning seat 10 to achieve precise positioning. The square slot 31 on the top of the positioning seat 10 not only avoids the guide rail protrusion structure to prevent positioning interference and ensure accurate coding position, but also facilitates quick disassembly and replacement after coding. After the guide rail body 29 is fully installed, the operator starts the electrical control box 1. At this time, the motor 32 in the displacement component starts. The motor 32 can drive the threaded screw 16 to rotate. When the threaded screw 16 rotates, the threaded sleeve 18 connected to its outer wall, together with the mounting plate 17 and the laser coder 13, can move smoothly along the slide groove 34 of the adjustment frame 11 to achieve precise adjustment of the coding position and improve coding adaptability and positioning accuracy. Furthermore, during the movement of the laser marking device 13, the gear disk 19 fixed to the rotating tube 22 meshes with the teeth 20 in the rectangular slot 15, thereby driving the rotating tube 22 to rotate synchronously. This causes the diversion tube 24, the arc tube 23, and the bend tube 25 to rotate synchronously with the marking device. At this time, the airflow provided by the external air supply system enters the rotating tube 22 and the diversion tube 24 through the hose 8 and the air guide tube 21, and continuously blows the head of the laser marking device 13 through the arc tube 23, thereby preventing the smoke from adhering to the end of the laser marking device 13 and affecting the quality of subsequent laser marking. Meanwhile, the airflow in another air path flows into the bend tube 25. At the same time, the speed-increasing component at the end of the bend tube 25, through the integrated structure of the expansion part 26, the narrow tube part 27, and the contraction part 28, utilizes the Venturi effect to increase the airflow velocity and enhance the blowing force. The cleaning effect allows for dust removal of the guide rail body 29 before coding, further improving the subsequent coding quality. During the speed-up component's blowing process, in conjunction with the rotation of the gear disk 19, the diverter pipe 24 and the arc-shaped pipe 23 can perform all-round reciprocating blowing of the coding area, removing floating dust from the guide rail surface without dead angles, ensuring the cleanliness of the substrate, and avoiding quality defects such as incomplete coding patterns, skewed characters, or insufficient adhesion caused by impurities from the source. At the same time, this follow-rotating blowing structure and displacement component form a spatial linkage, which not only ensures the coverage of a single blowing, but also adapts to the travel requirements of guide rails of different specifications, so that the equipment can still maintain clear coding edges and uniform color even in high-speed operation, significantly improving the appearance qualification rate and marking durability of the finished product.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
