Description

Technical Field

[0001] This invention relates to the field of Teflon tape technology, specifically to an integrated device for surface modification and cleaning of Teflon tape substrate. Background Technology

[0002] Teflon tape is a polymer composite tape made of polytetrafluoroethylene as the base material and high-temperature resistant adhesive layer. This material has excellent high temperature resistance, corrosion resistance, low surface energy, non-stick properties, and insulation and wear resistance. It is chemically stable and not easily corroded by acids, alkalis, or organic solvents. It is widely used in industrial fields such as electronics and electrical appliances, food processing, packaging sealing, industrial demolding, corrosion protection and insulation. In the existing technical field, due to the smooth and inert surface of Teflon tape substrate, it is extremely easy to adsorb dust, fine particles, and processing impurities during the production and processing process. In addition, the adhesion of the substrate surface is low, and it is difficult to directly attach the modified coating to the virgin substrate surface. Therefore, before surface modification processing, the substrate surface needs to be finely cleaned and impurity removed. Traditional processing methods mostly use a single wiping or simple blowing method to complete the impurity removal operation, which cannot distinguish between stubborn stains in local areas and light dust in the whole area. The cleaning level is vague, and it is easy to have local impurities and many cleaning dead corners. At the same time, conventional cleaning structures do not have dynamic multi-degree-of-freedom adjustment capabilities, the cleaning coverage is limited, and it is difficult to adapt to the impurity removal needs of substrates with different pollution distribution states. Moreover, dust is easily generated during the cleaning process, causing secondary pollution of the substrate. It cannot meet the requirements of large-scale and high-standard production and processing of high-precision Teflon tape. Summary of the Invention

[0009] Preferably, the visual inspection device acquires images of the substrate surface, identifies contaminated areas, and calibrates coordinates. When the contaminated area is moved above the support frame, the miniature electric telescopic rod drives the pressure roller downward to form an upper and lower clamp with the limiting roller to tension and fix the substrate. First, the detail cleaning mechanism is activated to complete the fixed-point cleaning of stubborn impurities in the local area. After resetting, the range cleaning mechanism is activated to complete the full-area deep cleaning of the substrate. The substrate is kept in a clamped state throughout the process to avoid cleaning deviation.

[0011] Preferably, the range cleaning mechanism further includes: a sliding groove, a fourth micro motor, a lead screw assembly, a limiting slider, a second cleaning brush, and a second helical gear; the sliding groove is fixedly installed at the bottom right side of the outer surface of the rotating frame in the front-rear direction; the fourth micro motor is fixedly installed at the rear side of the outer surface of the sliding groove, the rotating end of the fourth micro motor extends into the interior of the sliding groove, and the fourth micro motor is electrically connected to the controller; the lead screw of the lead screw assembly is fixedly installed at the front side of the rotating end of the fourth micro motor in the front-rear direction; the limiting slider is inserted into the inner right side of the sliding groove, and the inner left side of the limiting slider is connected to the lead screw nut of the lead screw assembly; the second cleaning brush is rotatably installed at the bottom right side of the limiting slider via a rotating shaft in the up-down direction, and the axis of the second cleaning brush extends out of the upper surface of the limiting slider; the second helical gear is keyed to the top end of the axis of the second cleaning brush, and the second helical gear meshes with the helical shaft gear.

[0012] Preferably, in the range cleaning process, the second cleaning brush always maintains a high-speed rotating cleaning state. The second cleaning brush is driven by the lead screw assembly to perform axial reciprocating horizontal sweeping in the front-back direction. At the same time, the second cleaning brush is driven by the worm gear assembly to perform circumferential arc sweeping around the axis of the fixed sleeve. The two types of adjustment actions are executed independently or in coordination. Relying on the sliding meshing characteristics of the first helical gear, the helical shaft gear and the second helical gear, all position and angle adjustments are completed under the condition of uninterrupted transmission of cleaning power.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. Visual inspection of the substrate surface is performed using a visual inspection device to identify the contaminated areas. The robotic arm is driven to move the housing to the contaminated area, and the lower surface of the first cleaning brush comes into contact with the surface of the contaminated area. The second motor drives the pulley inside the transmission belt assembly to rotate the belt. Under the transmission of the transmission belt assembly, the rotating drum seat is driven to rotate the first cleaning brush at high speed, so that the first cleaning brush cleans the contaminated area on the substrate surface. The dust collection suction cup sucks the debris removed by the first cleaning brush into the dust collection equipment through the connecting pipe.

[0014] 2. The dual-axis moving module drives the mounting frame to bring the second cleaning brush into contact with the substrate surface. The second micro motor drives the first helical gear to rotate inside the fixed sleeve. Under the drive of the first helical gear, the helical shaft gear meshes and transmits power to the second helical gear, causing the second helical gear to drive the second cleaning brush to rotate. Thus, the substrate surface is cleaned through the rotating end of the second cleaning brush. At the same time, by utilizing the axial sliding meshing structure between the helical shaft gear and the first and second helical gears, the rotating frame can complete the attitude and position adjustment while maintaining effective meshing between the helical shaft gear and the first and second helical gears and uninterrupted power transmission. The fourth micro motor drives the lead screw assembly to drive the limit slider, and the limit slider moves back and forth along the inner cavity of the slide groove. The directional translation allows the limiting slider to drive the second cleaning brush to complete the axial linear displacement adjustment along the sliding groove, thereby changing the radial displacement of the second cleaning brush so that it can perform a back-and-forth sweep on the substrate surface. At the same time, the third micro motor drives the worm in the worm gear assembly to rotate. Under the drive of the worm, the worm gear in the worm gear assembly drives the rotating frame to achieve a circumferential angle adjustment around the central axis of the fixed sleeve. This enables the rotating frame to drive the second cleaning brush below to move in an arc trajectory, making the cleaning surface of the second cleaning brush fan-shaped. The above-mentioned axial displacement and circumferential deflection adjustment actions can be performed individually or in conjunction. All adjustment operations can be completed in the dynamic operation state of the second cleaning brush continuously rotating, achieving a large-area overall cleaning of the substrate surface.

[0015] 3. The electric telescopic rod in the corresponding position of the conveying mechanism is shortened, and the support frame is driven to rotate axially forward inside the second fixed seat, so that the top roller is flipped from horizontal to vertical. The first micro motor cooperates to drive the top roller to rotate circumferentially, so as to realize the circumferential all-round cleaning operation of the conveying and cleaning mechanism on the outer wall of the top roller.

[0016] In summary, this invention achieves integrated continuous processing of substrate grading and surface modification, realizing a grading impurity removal mode that combines targeted fine removal of stubborn impurities with large-area uniform cleaning, thereby improving the surface cleanliness of the substrate. Simultaneously, the entire process employs a closed negative pressure dust collection method, effectively suppressing dust diffusion and preventing secondary contamination of the substrate. Furthermore, relying on a dynamically adjustable multi-degree-of-freedom cleaning structure, it can perform multi-dimensional adjustments to the cleaning position, angle, and amplitude while maintaining uninterrupted cleaning power transmission, achieving thorough surface purification of the substrate without dead angles. It also possesses autonomous cleaning and maintenance capabilities for the conveying components, periodically removing impurities adhering to the surface of the conveying parts, maintaining cleanliness of the conveying environment over the long term, reducing the probability of production contamination, effectively improving product processing consistency, and enhancing the overall quality and production efficiency of the Teflon tape.

The telescopic manipulator 82 can move horizontally synchronously with the ground rail platform 81, and also has multi-degree-of-freedom adjustment capabilities for vertical lifting, forward and backward extension, and angle fine adjustment. The telescopic manipulator 82 is controlled by the controller 3 to realize the automatic control of the extension stroke, lifting height, and clamping angle, which can flexibly adapt to external cleaning stations of different heights and positions. The dust collection shell 83 is fixedly installed on the bottom of the moving end of the telescopic manipulator 82. The rear discharge port of the dust collection shell 83 is connected to the dust collection device 9. Connected via a pipe, the rear side of the dust collection housing 83 has an arc-shaped groove. Inside the dust collection housing 83 is a sealed dust collection chamber. The arc of the rear groove matches the outer curvature of the conveying top roller 510, allowing for a semi-enclosed fit. A dust removal discharge interface is provided at the rear of the dust collection housing 83, connected to the dust collection equipment 9 via a pressure-resistant negative pressure hose, forming a sealed dust collection channel for the closed collection of dust, debris, and impurities generated during roller cleaning. The cleaning roller 84 is mounted on the top of the inner cavity of the dust collection housing 83 via bearings in the vertical direction.

[0025] The specific work steps are as follows: Step 1: The staff retrieves the internally preset automated processing program through the controller 3. The system starts the unwinding device 10, vision inspection device 11, micro electric telescopic rod 75, drive robotic arm 61, electromagnetic connection valve 68 and dust collection device 9 in sequence according to the logical timing. The unwinding device 10 is controlled to perform uniform unwinding operation, continuously feeding out the Teflon tape substrate wrapped inside the material roll. The strip substrate passes horizontally to the detection area below the vision inspection device 11, and then is flatly introduced into the top processing cavity of the base shell 1 through the feed port opened on the right side of the cover shell 2. The vision inspection device 11, equipped with a high-precision image recognition algorithm, collects images of the substrate surface in real time. Through image comparison, grayscale analysis and defect judgment algorithm, it identifies and locates the dust, glue stains and particulate impurities contaminated areas on the substrate surface, providing coordinate data for subsequent fixed-point cleaning. Step 2: The substrate to be inspected continues to be conveyed forward, passing through the inside of the range cleaning mechanism 7, and passing through the gap between the left and right limit rollers 74 and the pressure rollers 76 in sequence. When the contaminated area determined by visual inspection is moved to the upper part of the bearing processing plane of the support base 72, the two sets of miniature electric telescopic rods 75 simultaneously perform downward extension, driving the pressure rollers 76 assembled at the end to descend vertically. The pressure rollers 76 and the lower limit rollers 74 form an upper and lower clamping structure to flexibly press and limit the strip Teflon tape substrate. Step 3: After the substrate is positioned, the drive robotic arm 61 performs multi-degree-of-freedom displacement adjustment based on the contamination coordinate data detected by vision, driving the fixed end shell 62 to move precisely above the contaminated area of ​​the substrate, so that the lower surface of the first cleaning brush 64 mounted at the bottom of the shell 62 is in close contact with the contaminated surface of the substrate. The second motor 65 starts and outputs rotational power, driving the pulley inside the transmission belt assembly 66 to rotate. Relying on the synchronous transmission characteristics of the belt drive, the rotating drum 63 is driven to rotate at high speed, thereby causing the first cleaning brush 64 fixed to the bottom of the rotating drum 63 to rotate synchronously at high speed. The mechanical friction peeling action is used to finely grind and clean the local contaminated area, realizing the targeted removal of stubborn impurities and adhering particles. Step 4: During the cleaning operation, the electromagnetic connection valve 68 is opened to connect the pipeline, so that the vacuum cleaner 9, the connecting pipe and the dust collection nozzle 67 form a negative pressure connection loop. With the help of the negative pressure suction of the vacuum cleaner 9, a stable vacuum negative pressure zone is formed at the bottom of the dust collection nozzle 67. The dust and debris particles generated by the first cleaning brush 64 are sucked and transported to the vacuum cleaner 9 through the dust collection nozzle 67, the electromagnetic connection valve 68 and the connecting pipe under the action of negative pressure suction for centralized and sealed collection. After the local pollution area is cleaned, the mechanical arm 61 is driven to reset the entire cleaning component. Step 5: After the fixed-point fine cleaning operation is completed, the pressure roller 76 and the limit roller 74 inside the range cleaning mechanism 7 always maintain the clamping and locking state of the tape substrate. The controller 3 continues to execute the preset processing program and starts the dual-axis moving module 78, the second micro motor 712, the fourth micro motor 718, the third micro motor 714, the electromagnetic connection valve 68 and the dust collection device 9 in the logical sequence. The dual-axis moving module 78 drives the mounting frame 79 assembled at the bottom to achieve horizontal and vertical dual-axis linear displacement, and adjusts the initial working position of the second cleaning brush 721 so that the brush surface at the bottom of the second cleaning brush 721 is in contact with the clean processing surface of the Teflon tape substrate. Step 6: The second micro motor 712 outputs a constant rotational torque, driving the first helical gear 711 to rotate around a fixed axis inside the fixed sleeve 710. Based on the helical gear meshing transmission principle, the helical shaft gear 716 simultaneously forms a meshing transmission structure with the first helical gear 711 and the second helical gear 722. The power is transmitted step by step and drives the second helical gear 722 to rotate at high speed, thereby driving the second cleaning brush 721 at the bottom to rotate continuously. The high-speed friction of the brush bristles completes the overall cleaning and removal of impurities from the substrate surface. Due to the use of the helical gear sliding meshing structure, the helical shaft gear 716, the first helical gear 711 and the second helical gear 722 have axial sliding adaptation capabilities, so that the rotating frame 713 can flexibly complete the dynamic adjustment of spatial posture and working position under the dynamic working conditions of continuous gear meshing, uninterrupted power transmission and continuous rotation of the cleaning brush. Step 7: During the cleaning process, the fourth micro motor 718 drives the screw screw inside the lead screw assembly 719 to rotate on a fixed axis. Relying on the transmission conversion characteristics of the lead screw nut, the rotational motion is converted into linear reciprocating motion, which drives the limit slider 720 to move precisely in the front-back direction along the inner cavity of the slide groove 717. Simultaneously, it drives the second cleaning brush 721 to complete the axial linear displacement adjustment, change the radial coverage range of the cleaning, and realize the reciprocating flat sweeping operation of the substrate surface in the front-back direction. At the same time, the third micro motor 714 drives the worm inside the worm gear assembly 715 to rotate, driving the worm gear to return in a controlled manner. The rotation drives the rotating frame 713 to complete a high-precision circumferential angle fine adjustment around the central axis of the fixed sleeve 710, causing the second cleaning brush 721 to swing along an arc-shaped trajectory, forming a fan-shaped cleaning coverage area. The above-mentioned two types of adjustment actions, axial linear sweeping and circumferential arc swing, can be controlled independently or linked together. All position adjustment actions can be completed without stopping the machine while the second cleaning brush 721 rotates at high speed. Ultimately, a large-area overall deep cleaning of the Teflon tape substrate surface is achieved without dead corners and with full coverage, providing a high-standard processing base surface for subsequent modified spraying processes. Step 8: After the entire surface cleaning process of the substrate is completed, the miniature electric telescopic rod 75 inside the cleaning mechanism 7 is retracted upward in a controlled manner, which simultaneously drives the pressure roller 76 to move vertically upward, releasing the clamping and limiting state of the pressure roller 76 and the limiting roller 74 on the tape substrate. The substrate is restored to a conveyable and movable state. The unwinding device 10 maintains a uniform unwinding mode and continues to convey the cleaned tape substrate to the left, so that the strip substrate passes through the inside of the right conveying mechanism 5 and is clamped between the top roller 510 and the bottom roller 53. Step 9: Controller 3 continues to execute the automated process, sequentially starting drive motor 55, modified spraying equipment 4, air purification equipment 14, curing equipment 12 and winding equipment 13. Drive motor 55 outputs rotational power to directly drive the left bottom roller 53 to rotate on the fixed axis. At the same time, relying on the synchronous transmission of transmission gear set 54, it drives the right bottom roller 53 to rotate in the same direction and at the same speed. Relying on the friction between it and the substrate, it drives the tape substrate to move to the left, so that the substrate is transported to the internal spraying processing station of modified spraying equipment 4. Step 10: The modified coating equipment 4 uniformly sprays the modified coating onto the surface of the Teflon tape substrate that is stationary or moving at a constant speed at the work station. During the entire spraying process, the air purification equipment 14 installed on the top of the cover shell 2 runs continuously. It extracts the polluted air containing paint mist and volatile harmful gases inside the cover in real time through the air inlet that extends into the cavity at the top. After multi-stage filtration, adsorption and purification, the clean air that meets the standards is discharged to the external environment, reducing exhaust pollution. Step 11: After the substrate has been modified by spraying, it continues to be smoothly conveyed by the left conveying mechanism 5 and transferred to the curing equipment 12 so that the surface modified coating can be dried and cross-linked and cured quickly, so that the coating can be tightly bonded to the substrate. After the curing operation is completed and the coating is fully set, the modified Teflon tape is conveyed outward through the discharge port on the left side of the cover shell 2 and sent into the winding equipment 13 for uniform and orderly winding, thus completing the winding and storage of the finished product roll. Step 12: During the long-term continuous production operation of the device, the top roller 510 of the conveyor mechanism 5 is in long-term contact with the tape substrate and environmental dust. The outer wall of the roller is very easy to adhere to the adhesive residue, dust particles, and impurities. The maintenance and cleaning program built into the controller 3 can be triggered at timed intervals or manually. The system will start the ground rail platform 81, electric telescopic rod 58, telescopic manipulator 82, fifth micro motor 85 and first micro motor 59 in sequence. Step 13: The ground rail platform 81 drives the telescopic manipulator 82 mounted on the upper end to move horizontally and precisely in the left and right directions, so that the telescopic manipulator 82 moves as a whole to the rear working position of the conveying mechanism 5 to be cleaned. The electric telescopic rod 58 inside the conveying mechanism 5 is shortened and retracted in a controlled manner, pulling the support frame 57 to rotate and flip forward with the second fixed seat 56 as the rotation fulcrum, so that the top roller 510, which was originally in a horizontal clamping state, flips upward to a vertically exposed state, providing operating space for cleaning operations. Step 14: The telescopic manipulator 82, combined with its telescopic, lifting, and fine-tuning movements, moves the dust collection housing 83 to the cleaning station outside the top roller 510. The pre-set arc-shaped groove on the rear side of the dust collection housing 83 engages and fits with the outer wall of the top roller 510. At the same time, the outer wall of the cleaning roller 84 installed inside the dust collection housing 83 tightly abuts against the outer surface of the top roller 510. During the cleaning operation, the fifth micro motor 85 drives the cleaning roller 84 to rotate at high speed on a fixed axis. Relying on the frictional shearing force between the rollers, the stubborn impurities, adhesive stains, and dust adhering to the outer wall of the top roller 510 are physically peeled and polished. At the same time, the first micro motor 59 cooperates to drive the top roller 510 to rotate at a low speed and uniform circumferentially, realizing 360° all-round cyclic cleaning of the outer surface of the top roller 510 without dead angles. During the roller polishing and impurity removal process, all the dust debris and adhesive residue generated by peeling are collected in the sealed inner cavity of the dust collection housing 83 and continuously transported to the vacuum equipment 9 for centralized and sealed collection through the rear connecting pipe.
