[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 6 As shown in this embodiment, a multi-sided multi-color pad printing device includes a frame 1 and a robotic arm 2, a pad printing oiling part 3, a cleaning part 4, a mold feeding part 5, and a curing part 6 mounted on the frame 1.

[0028] The more specific structure is as follows:

[0029] The robotic arm 2 includes a robotic arm with a mechanical shaft 7 connected to it. A rotating disk 8 is connected to the end of the mechanical shaft 7. Silicone heads 9 are distributed around the rotating disk 8. Mechanical positioning holes are distributed on the rotating disk 8. Mechanical adjustment grooves 18 and locking screws are provided on the silicone heads 9. The locking screws pass through the mechanical adjustment grooves 18 and are threaded into the mechanical positioning holes.

[0030] An array of eight radial silicone heads 9 is formed, with each silicone head 9 independently controlled. Combined with a rotating disk 8, a three-dimensional trajectory optimization algorithm is used to achieve multi-color synchronous printing on multiple curved surfaces, avoiding the errors caused by traditional multiple positioning. Furthermore, the flexible silicone heads 9 and a high-precision six-axis robotic arm work together to accurately fit complex curved surface structures such as spherical and wavy surfaces through dynamic deformation compensation technology, breaking through the blind zone limitations of traditional pad printing and achieving synchronous positioning accuracy on multiple curved surfaces. The position of the silicone heads 9 can also be adjusted according to the position of the pad printing through the mechanical adjustment groove 18.

[0031] The pad printing oiling section 3 includes a steel plate 10 and an oil cup 11, the oil cup 11 moves horizontally on the steel plate 10; the pad printing oiling section 3 includes an oiling bracket 19, a cylinder base 20 is installed at the upper end of the oiling bracket 19, an oil replenishing cylinder 21 is fixed on the cylinder base 20, the drive end of the oil replenishing cylinder 21 is connected to the oil cup 11, and the steel plate 10 is fixed on the oiling bracket 19.

[0032] The sealed ink cup 11 significantly reduces ink evaporation, maintains stable ink concentration, and saves ink usage. Each ink cup 11 independently controls a specific color, avoiding cross-contamination during multi-color printing and ensuring color concentration in multi-color pad printing. The steel plate 10, manufactured with micron-level precision through laser engraving technology (±0.01mm), uses AI algorithms for intelligent layering design of the pattern, integrating pattern elements of the same color system onto a single steel plate 10, effectively meeting the precise overprinting requirements of multi-color printing. The ink replenishment cylinder 21 controls the forward movement of the ink cup 11 to replenish ink to the steel plate 10.

[0033] The cleaning section 4 includes a paper roll reel with a roller 12 mounted on it, and a support base plate 13 between the two paper roll reels. The cleaning section 4 also includes a cleaning bracket 22. The paper roll reels include a paper feed reel 23 and a paper take-up reel 24, which are located on both sides of the support base plate 13. A paper roll drive motor 25 is fixed on the cleaning bracket 22, and the drive end of the paper roll drive motor 25 is connected to the middle of the paper take-up reel 24. Guide shafts 27 are mounted on both sides of the support base plate 13, and a paper pressing shaft 28 is rotatably connected above the cleaning bracket 22.

[0034] By effectively removing residual ink after each pad printing by retracting and extending the paper, the problem of blurred patterns is avoided, making continuously printed patterns clearer, extending the service life of the silicone head 9, and reducing the replacement frequency of the silicone head 9. The cleaning bracket 22 retracts and extends from both sides, keeping the clean part of the cleaning paper 26 on the cleaning bracket 22 to clean the moving silicone head 9.

[0035] The mold feeding part 5 includes a linear feeding module 14. The driving end of the linear feeding module 14 is fixed with a positioning mold base plate 15. Several positioning mold parts 16 are evenly distributed on the positioning mold base plate 15.

[0036] Each side has a set of linear feeding modules 14. During the transfer printing process on one side, the other side can be used for feeding and unloading, improving production efficiency. The product 17 can be directly placed on the positioning module 16.

[0037] The curing section 6 includes a UV lamp tube that moves laterally on the frame 1; the curing section 6 includes a curing bracket 29, on which a curing transverse module 30 is mounted laterally; the UV lamp tube includes an upper surface UV lamp 31 and a side UV lamp 32, both of which are fixed on the drive end of the curing transverse module 30.

[0038] Equipped with a full-spectrum UV lamp for curing, it achieves millisecond-level curing of multi-color effects, with zero solvent evaporation throughout the process and VOC emissions of <5ppm.

[0039] It has three main characteristics:

[0040] 1. Integration of automation and precision mechanics: Multi-sided and multi-color intelligent pad printing integrates automated control, precision mechanics and intelligent algorithms to complete multi-sided and multi-color printing of complex structural parts in one go, eliminating the steps of multiple clamping and repeated baking in traditional processes, thus improving efficiency and quality;

[0041] 2. Integrated process: The design enables simultaneous printing of different surfaces, colors and patterns, optimizes the production process, reduces production costs, improves production efficiency, and meets diverse printing needs;

[0042] 3. Multifunctional collaboration: The flexible silicone head 9 is used in conjunction with a high-precision six-axis robot arm. Through dynamic deformation compensation technology, it can accurately fit the structure of complex curved surfaces and achieve synchronous positioning of multiple curved surfaces.

[0043] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
