Description

Technical Field

[0001] This utility model relates to the field of pad printing machine technology, specifically to a fully automatic intelligent high-speed pad printing machine. Background Technology

[0002] During the operation of pad printing machines, products need to be calibrated. The conventional calibration method in the existing technology is to visually position the product to the designated position. After the product is produced, it is inspected by professional testing equipment for size detection. Then, the operator performs data compensation. The operator needs to calculate the compensation data, and problems such as data calculation errors or input errors often occur, making equipment debugging complicated and difficult.

[0003] Common pad calibration involves increasing the ink pickup height along the Z-axis of the pad to reduce the amount of ink picked up. The ink is then removed onto a cleaning film. The operator judges whether the ink pickup around the pad is centered based on the pattern of the removed ink on the cleaning film. After the ink pickup is centered and adjusted, the Z-axis height is increased again to determine whether the ink pickup is complete. However, the centeredness and completeness of ink pickup rely entirely on the operator's subjective judgment, without any subsequent supervision. This results in instability in the size and appearance of the pad printing, as well as instability in the production life of the pad.

[0004] Meanwhile, traditional pad printing equipment suffers from poor coordination among its functional modules, unstable cleaning performance of the cleaning mechanism, cumbersome disassembly and assembly of the printing head assembly, and low efficiency in aligning the ink cup and printing head. These issues further exacerbate the difficulty of equipment debugging, reduce production continuity and automation levels, and fail to meet the demands of modern industry for high-speed, high-precision, and high-stability pad printing. Therefore, there is an urgent need to design a fully automatic, intelligent, high-speed pad printing machine that integrates intelligent correction, efficient cleaning, and convenient adjustment functions to address the pain points of existing technologies.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 10 As shown, a fully automatic intelligent high-speed pad printing machine includes a frame 1, an ink cup mechanism 2, a cleaning mechanism 3, a running table mechanism 4, a heating mechanism 5, a sampling inspection mechanism 6, a transition platform 7, a positioning vision mechanism 8, a correction vision mechanism 9, a pad printing X-axis module 10, a pad printing Y-axis module 11, a pad printing Z-axis module 12, a rotating mechanism 13, a correction camera 14, a cover plate 15, a first fixing plate 16, a drive motor 17, a rotating shaft 18, a locking cylinder 19, a cross roller bearing 20, a locking magnet 21, a mounting plate 22, a second fixing plate 23, a film roll unloading assembly 24, a film winding motor 25, a sensor 26, a cleaning film 27, a top plate 28, a cleaning position 29, a load-bearing plate 30, a negative pressure hole 31, a negative pressure chamber 32, a quick-release plate 33, an adjusting handle 34, a fixed base 35, a pad printing pad 36, an XYR module 37, a feeding robot 38, and a light source 39.

[0029] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing 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, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figures 1 to 10As shown, the fully automatic intelligent high-speed pad printing machine includes a frame 1. On the frame 1, there are symmetrically arranged oil cup mechanism 2, cleaning mechanism 3, running table mechanism 4 and heating mechanism 5 on the left and right sides and from front to back. In the middle of the frame 1, there are sampling inspection mechanism 6 and transition platform 7 arranged from front to back. Two sets of feeding robots 38 are arranged on the outside of the transition platform 7. The feeding robots 38 are slidably connected to the frame 1. The two sets of feeding robots 38 cooperate with the transition platform to realize the automated feeding of products and further improve production efficiency.

[0032] A positioning vision mechanism 8 is installed above the sampling inspection mechanism 6 and the transition platform 7. The positioning vision mechanism 8 is used to capture images of the product position on the running platform mechanism 4. In this embodiment, the positioning vision mechanism 8 is a combination of a commercially available industrial camera and lens. The working principle and structure have not been improved by this utility model, so they are not described in detail.

[0033] Two sets of correction vision mechanisms 9 are arranged parallel to each other on the upper side of the frame 1. The correction vision mechanisms 9 are used to capture the position and size of the ink removal pattern on the cleaning film 27 and the position and size of the product and pattern on the running table mechanism 4.

[0034] The positioning vision mechanism 8, located in the middle of the frame 1, can capture the product position on the running platform mechanism 4 in real time. Combined with the product size detection data of the sampling inspection mechanism 6, it can realize the automatic identification and deviation analysis of the product position. The calibration vision mechanism 9, through three-axis precision drive, works with the rotating mechanism 13 to drive the rubber head assembly to perform multi-dimensional compensation adjustment. No manual calculation or data input is required, which completely avoids human error, greatly simplifies the equipment debugging process, and improves the accuracy and efficiency of product positioning calibration.

[0035] like Figures 4 to 7 As shown, the correction vision mechanism 9 includes a pad printing X-axis module 10, a pad printing Y-axis module 11, a pad printing Z-axis module 12, a rotation mechanism 13, and a correction camera 14. The pad printing Y-axis module 11 is fixedly installed on the upper end of the frame 1. The pad printing X-axis module 10 is slidably installed on the pad printing Y-axis module 11. The pad printing Z-axis module 12 is slidably installed on the pad printing X-axis module 10. The lower end of the pad printing Z-axis module 12 is provided with a rotation mechanism 13, and the bottom of the rotation mechanism 13 is adapted to connect with the ink head assembly. A correction camera 14 is provided on one side of the pad printing Y-axis module 11. The correction camera 14 is set parallel to the rotation mechanism 13 and can accurately capture the ink removal pattern on the cleaning film 27, objectively determine the centering and integrity of the ink pick-up of the pad printing ink head 36, and replace the traditional manual subjective judgment.

[0036] The rotating mechanism 13 includes a cover plate 15, a fixed plate 16, a drive motor 17, a rotating shaft 18, a locking cylinder 19, a cross roller bearing 20, a locking magnet 21, and a mounting plate 22. The lower end of the pad printing Z-axis module 12 is fixedly connected to the upper end of the cover plate 15, and the lower end of the cover plate 15 is fixedly connected to the fixed plate 16. The upper end of the fixed plate 16 is equipped with the drive motor 17, and the output end of the drive motor 17 is connected to the rotating shaft 18. Locking cylinders 19 are respectively provided on both sides of the upper end of the rotating shaft 18. The lower end of the rotating shaft 18 is adapted to the cross roller bearing 20. The bearing clearance of the cross roller bearing 20 is 2μm, and the bearing capacity is 33000N to ensure the accuracy and load of the equipment. Multiple sets of locking magnets 21 are spaced apart and evenly arranged on the outer circumference of the cross roller bearing 20. Both the cross roller bearing 20 and the locking magnets 21 are set inside the mounting plate 22. The locking magnets 21 are used to fix the rotating shaft 18 during the operation of the glue head assembly to prevent the rotating shaft 18 from moving. The lower end of the mounting plate 22 is fixedly connected to the pad assembly. This ensures high precision in the rotational adjustment of the pad printing pad 36, effectively prevents displacement of the pad printing pad 36 during printing, significantly improves the dimensional accuracy and appearance consistency of the pad printing, and extends the service life of the pad printing pad 36.

[0037] The pad assembly includes a quick-release plate 33, an adjusting handle 34, a fixing base 35, and a pad printing pad 36. The lower end of the mounting plate 22 is fixedly connected to the quick-release plate 33. The quick-release plate 33 has an adjusting handle 34 on one side. The lower end of the quick-release plate 33 is detachably engaged with the fixing base 35. The pad printing pad 36 is fixedly installed on the lower end of the fixing base 35. The lower end of the quick-release plate 33 has an inwardly inclined closing surface. The fixing base 35 has beveled edges on both sides, which can fit against the closing surface. The adjusting handle 34 is used to adjust the tightness of one side of the quick-release plate 33. Loosening the adjusting handle 34 increases the gap on one side of the quick-release plate 33, allowing the beveled edges to slide smoothly out of the closing surface for quick disassembly or installation of the pad printing pad 36. Tightening the adjusting handle 34 quickly fixes the pad printing pad 36, ensuring stability during printing and reducing operational difficulty.

[0038] like Figure 8 and Figure 9As shown, the cleaning mechanism 3 includes a second fixed plate 23, a film roll assembly 24, a film winding motor 25, a sensor 26, a cleaning film 27, a top plate 28, a cleaning position 29, a load-bearing plate 30, a negative pressure hole 31, and a negative pressure chamber 32. Opposite fixed plates 23 are fixedly installed on the frame 1. The film roll assembly 24 is located on the inner side between the two fixed plates 23. The cleaning film 27 is attached to the film roll assembly 24. A sensor 26 is located between the film roll assemblies 24. The sensor 26 is used to sense the presence or absence of the cleaning film 27. In this embodiment, the sensor 26 is a market... As is common in the market, this utility model does not make any improvements to the sensing principle and method of sensor 26, so its sensing process is not described in detail; the input end of the film roll assembly 24 is electrically connected to the output end of the film winding motor 25; a top plate 28 is provided on the fixing plate 23, a cleaning position 29 is provided on the top plate 28, a load-bearing plate 30 is pressed on both sides of the cleaning position 29, the load-bearing plate 30 is made of transparent material, a light source 39 is provided at the lower end of the load-bearing plate 30, a negative pressure hole 31 is provided on both sides of the load-bearing plate 30, and a negative pressure cavity 32 is provided at the lower end of the negative pressure hole 31 and the lower end of the cleaning position 29.

[0039] The cleaning film 27 is wound around the film roll assembly 24, passing over the support plate 30 and the cleaning position 29. Under the adsorption of the negative pressure chamber 32, it adheres tightly to the surface of the cleaning position 29, ensuring a smooth and wrinkle-free film surface. After the pad printing head 36 completes its printing action, the correction vision mechanism 9 moves the printing head assembly downward, pressing the printing head 36 onto the cleaning film 27. The support plate 30 and the top plate 28 work together to provide stable support, allowing the cleaning film 27 to efficiently wipe away residual ink on the printing head surface. The film winding motor 25 automatically feeds a new section of cleaning film 27, ensuring that a clean area is used for each cleaning operation, improving cleaning consistency and the degree of equipment automation.

[0040] The bottom of the ink cup mechanism 2 is equipped with an XYR module 37, which is used to drive the ink cup mechanism 2 to rotate. The calibration camera 14 is directly fixed to the lower end of the pad printing Z-axis module 12. After the pad printing head 36 is de-inked by the cleaning mechanism 3, the positioning vision mechanism 8 confirms the size and position of the de-inked pattern and then adjusts the position of the ink cup mechanism 2 through the XYR module 37 to determine the ink picking position of the subsequent pad printing head 36.

[0041] This invention offers two adjustment methods. When the user selects to use the calibration vision mechanism 9 to adjust the position of the pad printing head 36, the XYR module 37 remains stationary. When the user selects to use the XYR module 37 to adjust the position of the ink cup mechanism 2, the pad printing Y-axis module 11 of the calibration vision mechanism 9 remains inactive. After the XYR module 37 completes its adjustment, the system automatically locks the position of the ink cup mechanism 2, ensuring accurate alignment of the pad printing head 36 in the next cycle. The entire adjustment process can be coordinated to avoid repeated adjustments that could lead to error accumulation, while simultaneously improving equipment response speed and stability, and ensuring consistent printing accuracy in continuous production.

[0042] The working principle of this utility model is as follows:

[0043] The vision correction mechanism 9 corrects the position of the pad printing head 36, the head assembly moves to the ink-taking position to complete ink taking, and the pad printing head 36 moves to the cleaning position 29 to complete ink removal;

[0044] The vision mechanism 9 captures the size and position of the ink removal pattern on the cleaning film 27, and guides the pad printing Y-axis module 11, pad printing X-axis module 10 and rotation mechanism 13 to change the correction compensation data until the position correction of the pad printing pad 36 is completed.

[0045] Positioning vision mechanism 8 corrects the product position, the glue head assembly and table mechanism 4 move to the printing position to complete the pad printing, the table mechanism 4 moves to below positioning vision mechanism 8, positioning vision mechanism 8 captures the pad printed product, determines the size and position of the product and the pad printed pattern, guides table mechanism 4 to correct the relative position of the product until the product position correction is completed.

[0046] This completes the automatic correction of the pad printing head 36 and the product position without manual intervention.

[0047] The various functional modules of this invention work together to improve space utilization and operational smoothness, meeting the heavy-duty requirements of the equipment while ensuring high-precision adjustment. Through an integrated design of intelligent correction, efficient cleaning, convenient adjustment, and structural optimization, this invention effectively solves the problems of complex debugging, insufficient precision, poor stability, and cumbersome operation in existing pad printing equipment. It balances printing accuracy, production efficiency, and operational comfort, adapting to the high-speed, high-precision pad printing processing needs of modern industry, and has significant practical value and promising prospects for widespread application.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of this utility model. Therefore, any modifications, equivalent changes, or improvements made in accordance with the claims of this utility model shall still fall within the scope of this utility model.
