Description

Technical Field

[0001] This application relates to the field of strip and coil processing technology, specifically to a roll-to-roll laser micro-hole processing device. Background Technology

[0002] Currently, roll-to-roll laser micro-hole processing equipment is required for micro-hole processing of rolled products.

[0003] Traditional single-point processing methods are inefficient and cannot meet the requirements of large-scale production, while roll-to-roll processing technology can achieve continuous material processing, improving production efficiency and product quality. However, most roll-to-roll laser micro-hole processing equipment currently has poor precision; at the same time, it cannot be adjusted according to material rolls of different thicknesses and materials, reducing the overall applicability of the processing. Utility Model Content

[0004] Therefore, this application provides a roll-to-roll laser micro-hole processing device to solve the problems of poor accuracy and inability to adjust for material rolls of different thicknesses and materials in existing equipment.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A roll-to-roll laser micro-hole processing device includes a frame, a fine-tuning component, and a cooling guide roller. An unwinding roller is rotatably installed on the left side inside the frame, and an unfolding roller is provided inside the frame. A take-up roller is installed in the middle of the inner side of the frame.

[0007] A fine-tuning component is installed on the upper inner side of the frame, and a linear guide rail is provided on the outer side of the upper end of the fine-tuning component. A matching slider is installed on the lower end of the linear guide rail, and a laser is fixedly installed on the outer side of the lower end of the slider.

[0008] A cooling guide roller, also located within the frame, is positioned directly below the laser, and cooling pipes are installed inside the cooling guide roller.

[0009] Furthermore, both the unwinding roller and the take-up roller are rotatably connected to the frame, and the take-up roller is located to the upper right of the unwinding roller.

[0010] Furthermore, the cooling guide rollers are arranged in a one-to-one correspondence with the laser, and the cooling guide rollers have a double-layer structure.

[0011] Furthermore, two sets of plasma cleaning equipment are also installed on the inner side of the frame, and a gas purifier is fixedly installed in the middle of the upper end of the frame.

[0012] Furthermore, the fine-tuning component includes a servo motor, a coupling, a bottom differential screw, a top differential screw, and a differential nut. The servo motor is fixedly installed on the inner side of the frame, and the output end of the servo motor is connected to the coupling. The bottom differential screw is connected to the outer side of the upper end of the coupling.

[0013] Furthermore, a top differential screw is installed on the outer side of the upper end of the bottom differential screw, and a differential nut located on the outer side of the bottom differential screw is connected to the outer side of the top differential screw.

[0014] Furthermore, the bottom differential screw and the slider have different pitches, and the pitch of the bottom differential screw is 0.1mm-0.3mm larger than that of the top differential screw.

[0015] Furthermore, the differential nut and the top differential screw are fitted with a clearance fit and a transition fit. The inner hole of the differential nut has two planes, and the outer surfaces of the bottom differential screw and the top differential screw are milled planes that fit with the differential nut.

[0016] Furthermore, the cooling pipeline is externally connected to a rotary water-cooling connector, and the rotary water-cooling connector is connected to a cooling unit via a pipeline.

[0017] Compared with the prior art, this application has at least the following beneficial effects:

[0018] 1. A differential screw drive is formed by the bottom differential screw and the top differential screw cooperating with the differential nut. By adjusting the rotation direction and speed of the bottom differential screw and the top differential screw, the movement direction and distance of the differential nut can be changed. This allows the differential nut to move precisely in a straight line according to the rotation of the bottom differential screw and the top differential screw, thereby adjusting the position of the linear guide rail up and down. This facilitates the adjustment of the laser position and allows for adjustment according to material rolls of different thicknesses and materials, improving the overall applicability of the processing.

[0019] 2. The cooling guide rollers and the laser are set up in a one-to-one correspondence. The cooling guide rollers provide good support for the material roll, which facilitates the laser to perform laser micro-hole processing on the material roll located on the cooling guide rollers.

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

[0028] like Figures 1 to 4 As shown in the embodiment of this application, a roll-to-roll laser micro-hole processing device includes: a frame 1, a fine-tuning component and a cooling guide roller 4. An unwinding roller 2 is rotatably installed on the left side inside the frame 1, and an unfolding roller 3 is provided inside the frame 1. A take-up roller 9 is installed in the middle of the inner side of the frame 1.

[0029] The unwinding roller 2 and the take-up roller 9 are both connected to the frame 1 by rotation, and the take-up roller 9 is located to the upper right of the unwinding roller 2. The front ends of the unwinding roller 2, the take-up roller 9 and the cooling guide roller 4 are all connected to a transmission system located outside the frame 1. The transmission system includes a servo / stepper motor, a reducer and a transmission roller. The servo / stepper motor and reducer drive the transmission and control it through an encoder and a PLC, which can realize continuous / intermittent transmission of the coiled strip.

[0030] A drive motor directly drives the transmission roller to rotate, thereby enabling the transmission roller to drive the unwinding roller 2 and the take-up roller 9 to rotate respectively, thus ensuring smooth transfer of the material roll between the unwinding roller 2 and the take-up roller 9. The unwinding roller 2 is used to wind the material roll to be processed, and the take-up roller 9 is used to wind the processed material roll. A laser 7 is positioned between the unwinding roller 2 and the take-up roller 9 for laser micro-hole processing of the material roll.

[0031] The two sets of stretching rollers 3 are arranged in a reasonable manner and located on the lower left side of the corresponding cooling guide rollers 4. This allows the stretching rollers 3 to effectively prevent wrinkles from forming in the material roll, ensuring a smooth surface for the material roll and providing a good foundation for subsequent laser micro-hole processing.

[0032] This equipment also includes a control system, which controls the operation of the entire system, including adjusting parameters such as feeding speed, discharging speed, laser power, and laser scanning speed. The control system can also monitor the equipment's operating status in real time, such as the tension and position of the material roll, and make corresponding adjustments based on the monitoring results.

[0033] A fine-tuning component is installed on the upper inner side of the frame 1. A linear guide rail 5 is provided on the outer side of the upper end of the fine-tuning component. A matching slider 6 is installed on the lower end of the linear guide rail 5, and a laser 7 is fixedly installed on the outer side of the lower end of the slider 6.

[0034] The linear guide 5 ensures the positional accuracy and speed stability of the slider 6 and the laser 7. The laser 7 includes a laser generator, an optical system, and a processing head. The laser generator produces a laser beam, and the optical system, including lenses and mirrors, focuses and collimates the laser beam, ensuring it accurately illuminates the material roll. The processing head is a scanning head, capable of rapidly scanning the material roll for efficient laser micro-hole processing. Its design adapts to material rolls of varying thicknesses and materials, offering broad applicability. The aperture range of the laser micro-holes is 20µm-3000µm.

[0035] It adopts an advanced laser control system to achieve precise control of parameters such as laser power and laser scanning speed, thereby improving processing accuracy and quality. At the same time, combined with the transmission system and control system, it has good stability and reliability, and can operate continuously for a long time.

[0036] A cooling guide roller 4 is located directly below the laser 7 and is also located in the frame 1. A cooling pipe 12 is installed inside the cooling guide roller 4. The cooling guide roller 4 has a double-layer structure. A rotary water-cooling connector is connected to the outside of the cooling pipe 12. The rotary water-cooling connector is connected to the cooling unit 11 through a pipe.

[0037] In this design, the cooling guide roller 4 and the laser 7 are arranged in a one-to-one correspondence, with the cooling guide roller 4 providing good support for the material roll, facilitating laser micro-hole processing of the material roll located on the cooling guide roller 4 by the laser 7. Simultaneously, the cooling pipe 12 forms a complete cooling circuit with the cooling unit 11 through a rotary water-cooling joint and pipes. The cooling medium enters the rotary water-cooling joint from the cooling unit 11 through the pipes, and is then transported to the cooling guide roller 4 through internal channels. Inside the cooling guide roller 4, the cooling medium absorbs heat and then returns, completing the cooling cycle. This facilitates the cooling of the cooling guide roller 4, thereby preventing the material roll from deforming due to the high temperature of laser processing. The rotary water-cooling joint is existing technology and will not be described in detail here.

[0038] The fine-tuning assembly includes a servo motor 13, a coupling 14, a bottom differential screw 15, a top differential screw 16, and a differential nut 17. The servo motor 13 is fixedly mounted on the inner side of the frame 1, and the output end of the servo motor 13 is connected to the coupling 14. The bottom differential screw 15 is connected to the outer side of the upper end of the coupling 14. The top differential screw 16 is mounted on the outer side of the upper end of the bottom differential screw 15, and the differential nut 17, located outside the bottom differential screw 15, is connected to the outer side of the top differential screw 16.

[0039] The bottom differential screw 15 and the slider 6 have different pitches, and the pitch of the bottom differential screw 15 is 0.1mm-0.3mm larger than that of the top differential screw 16. Each rotation can achieve an adjustment of 0.1-0.2mm for the top differential screw 16. The differential nut 17 and the top differential screw 16 are fitted with clearance fit and transition fit. The inner hole of the differential nut 17 has double planes. The outer surfaces of the bottom differential screw 15 and the top differential screw 16 are milled planes that fit with the differential nut 17 to facilitate circumferential locking of the differential screw.

[0040] The bottom differential screw 15 and the top differential screw 16 are the core components of the fine-tuning assembly. They cooperate with the differential nut 17 to form a differential screw drive. By adjusting the rotation direction and speed of the bottom differential screw 15 and the top differential screw 16, the movement direction and distance of the differential nut 17 can be changed, thereby achieving precise adjustment of the material roll.

[0041] The differential nut 17 is the actuator of the fine-tuning assembly. It works with the bottom differential screw 15 and the top differential screw 16 to achieve linear motion.

[0042] The upper end of the differential nut 17 is connected to the linear guide rail 5. The differential nut 17 moves precisely in a straight line according to the rotation of the bottom differential screw 15 and the top differential screw 16, thereby adjusting the position of the linear guide rail 5 up and down. This facilitates the adjustment of the position of the laser 7 and allows for adjustment according to material rolls of different thicknesses and materials, improving the overall applicability of the processing.

[0043] A laser level calibrator is installed on the side of the linear guide rail 5. The output of the laser level is associated with the fine-tuning components, which directly drive the fine-tuning components on both sides of the linear guide rail 5 to achieve precise fine-tuning of the laser 7 during the up-and-down adjustment process and ensure that it is level.

[0044] Two sets of plasma cleaning equipment 8 are also installed on the inner side of the rack 1, and a gas purifier 10 is fixedly installed in the middle of the upper end of the rack 1.

[0045] The plasma cleaning equipment 8 uses plasma to treat the material surface, effectively removing organic pollutants, oxides, and particles. This cleaning method is not only highly efficient but also environmentally friendly, producing no harmful waste. The main function of the gas purifier 10 is to purify these exhaust gases, ensuring that the emitted air is clean and harmless. It uses technologies such as filtration, adsorption, and catalytic oxidation to convert harmful substances in the exhaust gas into harmless substances, such as carbon dioxide and water.

[0046] When the thickness of the material roll changes, the movement distance of the differential nut 17 can be changed by adjusting the rotational speed difference between the bottom differential screw 15 and the top differential screw 16, thereby achieving compensation and adjustment of the material roll thickness.

[0047] Working principle

[0048] The entire assembly is placed stably on a designated plane. The servo motor 13 is started, causing the servo motor 13 to drive the bottom differential screw 15 to rotate through the coupling 14. The difference in rotational speed between the bottom differential screw 15 and the top differential screw 16 is adjusted to change the moving distance of the differential nut 17, thereby realizing the height adjustment of the linear guide rail 5, the slider 6 and the laser 7. This allows for adjustment according to material rolls of different thicknesses and materials, improving the overall processing applicability.

[0049] The material roll to be processed is then mounted on the unwinding roller 2. The transmission system connected to the unwinding roller 2 is activated, causing the material roll to slowly enter the frame 1 under the drive of the unwinding roller 2 and sequentially contact the first set of unwinding rollers 3 and the first set of cooling guide rollers 4. The laser 7 corresponding to the first set of cooling guide rollers 4 is activated, enabling the laser 7 to quickly scan the material roll and achieve efficient laser micro-hole processing. During laser micro-hole processing, the cooling pipe 12 can cool the cooling guide rollers 4, thereby preventing the material roll from deforming due to the high temperature of the laser processing. After processing, the plasma cleaning equipment 8 treats the material surface with plasma to remove organic contaminants, oxides, and particles.

[0050] Similarly, the material roll after the first laser micro-perforation is moved again following the steps described above, sequentially contacting the second set of unwinding rollers 3 and the second set of cooling guide rollers 4. The laser 7 corresponding to the second set of cooling guide rollers 4 is then activated, enabling the laser 7 to rapidly scan the material roll and perform laser micro-perforation again. The processed material roll is then output from the take-up roller 9. The control system monitors the equipment's operating status in real time and adjusts parameters such as feed rate, output rate, laser power, and laser scanning speed as needed to ensure processing quality and efficiency.

[0051] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
