Description

Technical Field

[0001] This application relates to the field of new material thin film processing technology, specifically a damage detection device for new material thin film processing. Background Technology

[0002] New material films refer to sheet-like functional materials prepared using novel materials as substrates and through specific processes. Their core characteristics are that through innovation in material composition, structural design, or upgrades in preparation processes, they possess the properties of traditional films, such as ordinary plastic films, metal foils, and glass films, or achieve significant breakthroughs in performance, such as higher strength, better environmental resistance, and special functional responses. During the processing of new material films, damage detection devices are needed to detect whether there is any damage on the film to ensure the quality of film products and production efficiency.

[0003] For example, patent CN209727789U discloses a film tearing damage detection device. This patent uses optical fibers to detect whether the film is damaged during the automatic film tearing process more quickly, accurately and densely, so as to reduce false detections and missed detections. However, in actual use, because there is a certain gap between each set of transmitting and receiving optical fibers, when the damage on the film appears at the gap, it is easy to miss the detection, resulting in the overall detection accuracy being relatively poor.

[0008] Furthermore, the side plate is fixedly connected to the fiber optic distribution plate, and the fiber optic distribution plate is fixedly connected to the support.

[0009] Furthermore, a cleaning assembly is provided on the top of the support, and the cleaning assembly includes a vertical plate. The vertical plate is placed on the top of the support, and a dust collection box is fixed at the upper end of the vertical plate. A brush head is provided on the top of the dust collection box, and a filter box is slidably connected inside the dust collection box. An air cylinder is fixed at the bottom of the brush head, and a double-headed piston rod is slidably connected inside the air cylinder. A first one-way valve is provided on one side of the air cylinder, and a second one-way valve is also provided on one side of the air cylinder. The second one-way valve is connected to a flow collector plate through a pipe, and an air jet head is provided on one side of the flow collector plate.

[0010] Furthermore, the first one-way valve is connected to the dust collection box via a pipe, and the dust collection box is fixedly connected to the manifold.

[0011] Furthermore, the double-ended piston rod is fixedly connected to the movable plate, and two double-ended piston rods are symmetrically arranged about the center line of the movable plate.

[0012] Furthermore, bearing seats are installed at the four corners of the top surface of the base plate, and the upper end of the bearing seat is connected to the roller through the bearing. Limiting rings are sleeved on the outer sides of both ends of the roller.

[0013] Furthermore, the end of the idler roller is connected to an adjustment assembly, and the adjustment assembly includes a fixed cover.

[0014] Furthermore, a pulley seat is provided on one side of the limiting ring, and a baffle is fixed to one end of the pulley seat. A reflector is connected to one end of the baffle.

Beneficial effects

[0015] 1. In this application, the light source emits light through the transmitting optical fiber, and the receiving end receives the light reflected from the thin film surface and transmits it to the CCD camera through the receiving optical fiber. The surface damage is accurately detected by recognizing the change in brightness. At the same time, the motor drives the movable plate to move the transceiver back and forth, which expands the single-point static detection into linear scanning, significantly increases the detection coverage area in a single scan, eliminates the detection blind zone under the traditional fixed spacing, and realizes full-range coverage detection. At the same time, the reflector provides reflective surfaces on both sides of the thin film to avoid misjudgment due to the lack of reflected light and improves the adaptability of the device to thin films of different widths.

[0016] 2. During the film movement process, this application automatically cleans the surface with a brush head to prevent dust and impurities from adhering to the reflective part of the film and causing false alarms. In addition, the reciprocating movement of the movable plate will drive the double-headed piston rod to change the volume of the air cylinder. When the volume increases, the first one-way valve will draw in the dust collection box to collect the dust swept off by the filter brush. When the volume decreases, the second one-way valve will send the airflow to the collecting plate and spray it out from the nozzle to form a continuous clean air curtain around the optical element, blowing away the floating dust and repelling the light-loving insects, ensuring the quality of the optical signal. At the same time, the multi-air cylinder design maintains the stability of the airflow, improving the reliability of detection from both cleaning and protection aspects.

[0017] 3. This application utilizes a limiting ring to guide and limit the film on both sides, preventing deviation during testing. The rotating worm gear drives the positive and negative thread screws to rotate via the worm wheel, adjusting the position of the limiting ring to adapt to films of different widths, thus improving the equipment's adaptability. The self-locking performance of the worm wheel and worm gear ensures stability after adjustment. During the adjustment process, the limiting ring also drives the baffle and reflector to move synchronously via the pulley seat. The baffle blocks both ends of the brush head to maintain the dust collection efficiency of the central negative pressure zone, while the reflector provides a reflective background. This linkage design eliminates the need for separate calibration steps for multiple components, significantly improving the efficiency of equipment debugging and changeover.

[0021] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Please see Figures 1 to 3 This application provides a new material thin film processing damage detection device, including a base plate 1 and a moving component 4. A support 2 is fixed in the middle of the top surface of the base plate 1, and a detection component 3 is connected to one side of the support 2. The detection component 3 includes a light source 301. The light source 301 is placed on one side of the support 2, and a transmitting optical fiber 302 is provided on one side of the light source 301. An optical fiber distribution plate 303 is provided on the outer side of one end of the transmitting optical fiber 302, and a movable plate 304 is fixed on the outer side of the other end of the transmitting optical fiber 302. A transmitting end 305 is provided on one side of the movable plate 304, and a receiving end 306 is also provided on one side of the movable plate 304. A receiving optical fiber 307 is connected to one end of the receiving end 306, and a CCD camera 308 is provided at the lower end of the receiving optical fiber 307. The CCD camera 308 is fixedly connected to the support 2, and the moving component 4 is provided on one side of the detection component 3.

[0025] In some embodiments, the moving component 4 includes a motor 401, one end of the support 2 is equipped with the motor 401, and the output end of the motor 401 is connected to a synchronous shaft 402. Guide wheels 403 are fixed to the outer sides of both ends of the synchronous shaft 402, and guide grooves 404 are opened on the outer sides of the guide wheels 403. Guide posts 405 are slidably connected inside the guide grooves 404. A light rod 406 is provided on one side of the detection component 3, and side plates 407 are fixed to both ends of the light rod 406. A movable plate 304 is fixedly connected to a receiving optical fiber 307, and the movable plate 304 is slidably connected to the light rod 406. The movable plate 304 is rotatably connected to the guide posts 405. The side plate 407 is fixedly connected to an optical fiber distribution plate 303, and the optical fiber distribution plate 303 is fixedly connected to the support 2.

[0026] Understandably, when the light source 301 emits light through the transmitting fiber 302 to the transmitting end 305, the receiving end 306 receives the light reflected from the surface of the new material film and transmits the light signal to the CCD camera 308 through the receiving fiber 307. The CCD camera 308 captures and identifies changes in light brightness in real time, thereby accurately determining whether there is damage on the surface of the new material film. During the detection process, the motor 401 can also be activated, causing it to drive the guide wheel 403 to rotate through the synchronous shaft 402. This, in turn, drives the movable plate 304 to move through the guide groove 404. At this time, the light rod 406 can guide the movement of the movable plate 304. The moving direction limit guides it to reciprocate along the axis of the movable plate 304, which expands the single-point static detection into linear scanning detection, thereby expanding the detection range of the detection component 3, completely eliminating the detection blind zone caused by the spacing of the traditional fixed optical fiber group, and achieving full-range coverage. In addition, the reflector 908 can be used to block the two sides of the narrow new material film, so that when there is no effective reflective surface on both sides of the new material film, the light emitted by the transmitter 305 can be accurately transmitted to the receiver 306 after being reflected by the reflector 908, avoiding the system from misjudging the damage defect due to the lack of reflected light on both sides, and improving the adaptability of the device to films of various specifications.

[0027] Please see Figure 4 and Figure 5 A cleaning assembly 5 is provided on the top of the support 2, and the cleaning assembly 5 includes a vertical plate 501. The vertical plate 501 is placed on the top of the support 2, and a dust collection box 502 is fixed to the upper end of the vertical plate 501. A brush head 503 is provided on the top of the dust collection box 502, and a filter box 504 is slidably connected inside the dust collection box 502. An air cylinder 505 is fixed to the bottom of the brush head 503, and a double-headed piston rod 506 is slidably connected inside the air cylinder 505. A first single... The first check valve 507 is connected to the first dust collection box 502 through a pipe, and the dust collection box 502 is fixedly connected to the dust collection plate 509. The second check valve 508 is connected to the first check valve 507 through a pipe, and the second check valve 508 is connected to the first check valve 507 through a pipe, and the dust collection box 502 is fixedly connected to the dust collection plate 509. The double-headed piston rod 506 is fixedly connected to the movable plate 304, and there are two double-headed piston rods 506 symmetrically arranged about the center line of the movable plate 304.

[0028] When the external winding equipment moves the film above the damage detection device, the brush head 503 automatically cleans the film surface, preventing dust and impurities from adhering to the surface of the new film material and causing false alarms during detection. During the reciprocating movement of the movable plate 304, the double-headed piston rod 506 also reciprocates, changing the internal volume of the air cylinder 505. When the internal volume of the air cylinder 505 increases, it draws suction from the dust collection box 502 through the first one-way valve 507. At this time, the top of the dust collection box 502 absorbs the dust and impurities swept off by the brush head 503 and collects them through the filter box 504. The filter screen inside the filter box 504 is V-shaped, which increases the overall dirt-holding capacity. When the air cylinder 505... When the volume of the part decreases, the air inside is delivered to the collector plate 509 through the second one-way valve 508, and blown towards the transmitter 305 and receiver 306 through the jet head 510, forming a continuous and clean air curtain around the optical transmitter 305 and receiver 306. This air curtain can blow away any dust that may fall, preventing it from adhering and affecting the light transmittance and signal quality of the transmitter 305 and receiver 306. The continuous airflow disturbance can also repel light-loving mosquitoes, avoiding the obstruction of the light path or the generation of false signals due to mosquitoes staying there. This fundamentally ensures the high signal-to-noise ratio and stability of the detection signal. In addition, multiple air cylinders 505 are provided to continuously deliver airflow, which is conducive to ensuring the quality of detection.

[0029] Please see Figure 2 , Figure 6 and Figure 7 Bearing seats 6 are installed at the four corners of the top surface of the base plate 1, and the upper end of the bearing seat 6 is connected to the roller 7 through the bearing. Limiting rings 8 are sleeved on the outer sides of both ends of the roller 7, and the end of the roller 7 is connected to the adjustment component 9.

[0030] In some embodiments, the adjusting assembly 9 includes a fixed cover 901, one end of the roller 7 is provided with the fixed cover 901, and a worm gear 902 is rotatably connected inside the fixed cover 901. A worm wheel 903 is engaged on one side of the worm gear 902, and a threaded screw 904 is fixed inside the worm wheel 903. The threaded screw 904 is rotatably connected to the roller 7. Threaded sleeves 905 are threaded to the outer sides of both ends of the threaded screw 904, and the threaded sleeves 905 are fixedly connected to the limiting ring 8. A pulley seat 906 is provided on one side of the limiting ring 8, and a baffle 907 is fixed to one end of the pulley seat 906. A reflector 908 is connected to one end of the baffle 907. A support plate 909 is fixed to the bottom of the baffle 907, and a guide rod 910 is slidably connected inside the support plate 909. The guide rod 910 is fixedly connected to the dust collection box 502.

[0031] It should be noted that the above-mentioned structure of this application utilizes the limiting ring 8 to limit and guide the new material film on both sides of the roller 7, preventing the new material film from deviating or tilting during testing. In addition, rotating the worm 902 drives the positive and negative thread screw 904 to rotate through the worm wheel 903, which in turn changes the position of the limiting ring 8 through the screw sleeve 905, thereby expanding the adaptability range of the equipment. At the same time, the self-locking performance of the worm 902 and the worm wheel 903 enhances the stability after adjustment. During the adjustment process, the limiting ring 8 also drives the baffle 907 and reflector 908 to move synchronously through the pulley seat 906, while the support plate 909 and guide... The rod 910 limits and guides the baffle 907 and reflector 908 to simultaneously block both sides of the new material film. At this time, the baffle 907 blocks the openings at both ends of the brush head 503, which can maintain the negative pressure intensity of the negative pressure adsorption area in the middle of the brush head 503, and avoid the airflow dispersion caused by the openings at both ends, thus reducing the dust collection efficiency in the central area and ensuring the cleaning effect. The synchronous movement of the reflector 908 provides a stable background reflective surface for narrow film detection. This linkage design eliminates the tedious steps of individually and repeatedly calibrating multiple components, and significantly improves the operational efficiency and accuracy during equipment debugging and model changeover.

[0032] In summary, when using the above-mentioned new material film processing damage detection device, first rotate the worm 902, and drive the positive and negative thread screw 904 to rotate through the worm wheel 903. Then, the position of the limiting ring 8 can be changed through the screw sleeve 905, so that the limiting ring 8 limits and guides the new material film on both sides of the roller 7, and avoids the new material film from running off-center or tilting during subsequent inspection. Next, during the adjustment process, the limiting ring 8 also drives the baffle 907 and reflector 908 to move synchronously through the pulley seat 906, while the support plate 909 and guide rod 910 limit and guide them, so that the baffle 907 and reflector 908 simultaneously block both sides of the new material film. At this time, the baffle 907 blocks the openings at both ends of the brush head 503, which can maintain the negative pressure intensity of the negative pressure adsorption area in the middle of the brush head 503, and avoid the airflow dispersion caused by the openings at both ends, thus reducing the dust collection efficiency of the central area. The synchronous movement of the reflector 908 provides a stable background reflective surface for narrow film detection. This linkage design eliminates the tedious steps of individually and repeatedly calibrating multiple components, and significantly improves the operational efficiency and accuracy during equipment debugging and model change. Then, when the external conveying and tensioning equipment tensions and conveys the new material film, the brush head 503 can be used to automatically clean the film surface, avoiding dust and impurities adhering to the surface of the new material film and causing false alarms during detection. Afterwards, the light source 301 emits light through the transmitting fiber 302 to the transmitting end 305, and the receiving end 306 receives the light reflected from the surface of the new material film. The light signal is then transmitted to the CCD camera 308 through the receiving fiber 307. The CCD camera 308 captures and identifies changes in light brightness in real time, thereby accurately determining whether there is any damage on the surface of the new material film. During the detection process, the motor 401 can also be started, causing it to move through the synchronous shaft 4 02 drives the guide wheel 403 to rotate, which in turn drives the movable plate 304 to move through the guide groove 404. At this time, the light rod 406 can limit and guide the movement direction of the movable plate 304, so that it reciprocates along the axis of the movable plate 304, thereby expanding the detection range of the detection component 3, completely eliminating the detection blind zone caused by the spacing of the traditional fixed optical fiber group, and achieving full coverage. In addition, the reflector 908 can be used to block the two sides of the narrow new material film, so that when there is no effective reflective surface on both sides of the new material film, the light emitted by the transmitter 305 can be accurately transmitted to the receiver 306 after being reflected by the reflector 908, avoiding the system from misjudging the damage defect due to the lack of reflected light on both sides. Finally, during the reciprocating translation of the movable plate 304, the double-headed piston rod 506 also reciprocates, thereby changing the internal volume of the air cylinder 505. When the internal volume of the air cylinder 505 increases, it draws suction from the dust collection box 502 through the first one-way valve 507. At this time, the dust collection box 502 adsorbs the dust and impurities swept off by the brush head 503 at the top and collects them through the filter box 504. The filter screen inside the filter box 504 is V-shaped, which can increase the overall dirt holding capacity. When the internal volume of the air cylinder 505 decreases, its internal volume decreases. The air from the part is delivered to the collector plate 509 through the second one-way valve 508, and blown towards the transmitter 305 and receiver 306 through the jet head 510, forming a continuous and clean air curtain around the optical transmitter 305 and receiver 306. This air curtain can blow away any dust that may fall, preventing it from adhering and affecting the light transmittance and signal quality of the transmitter 305 and receiver 306. The continuous airflow disturbance can also repel light-loving mosquitoes, avoiding the blocking of the light path or the generation of false signals due to mosquitoes staying there.
