Description

Technical Field

[0001] This invention belongs to the field of fiber cloth inspection, specifically relating to a defect detection device for a new type of fiber cloth. Background Technology

[0002] Defect detection of new material fiber cloth involves using a camera to photograph the surface pattern of the new material fiber cloth after production to determine whether the pattern is missing or complete, or by shining light on the pattern area of ​​the new material fiber cloth and judging its light transmittance.

[0003] Patent CN206583815U discloses a defect detection device for fiberglass cloth, including a controller, multiple cameras located above a conveyor belt, and a display screen. The camera near the front end of the conveyor belt is a primary detection camera fixed to a bracket; the cameras located above the middle of the conveyor belt are three positioning cameras fixed to a bracket; and the camera near the rear end of the conveyor belt is a fine detection camera, which is slidably mounted on a horizontal guide rail perpendicular to the conveyor belt. The primary detection camera is a panoramic camera, the positioning cameras are close-up cameras, and the fine detection camera is a 10x zoom close-up camera. The multiple cameras, the sliding drive device for the fine detection camera, and the display screen are all connected to the controller. This device can accurately identify foreign objects on the fiberglass cloth, allowing for appropriate manual handling and preventing incorrect recycling, which would increase processing costs.

[0004] However, the above-mentioned device has the following problems: When performing pattern integrity testing on new material fiber cloth, the detection pattern needs to be edited to ensure that the camera compares the edited pattern to detect the pattern on the limit plate. If other patterns need to be detected, the pattern needs to be re-edited, which is very troublesome. Summary of the Invention

[0005] The purpose of this invention is to provide a defect detection device for new material fiber cloth, so as to solve the problem that detection equipment is difficult to detect different fiber cloth patterns.

[0006] To achieve the above objectives, the present invention provides a defect detection device for a novel material fiber cloth, comprising: The outer casing has an openable rotating door installed at the front. A support plate is fixedly installed on the inner wall of the outer casing. A roller is rotatably connected to the inner wall of the support plate via a connecting rod. Fabric is wound around the circumference of the roller. An illumination mechanism is provided on the top of the housing. The illumination mechanism includes a hydraulic cylinder, and a mounting plate is fixedly installed on the output end of the hydraulic cylinder. A lamp is installed on the inner wall of the bottom of the mounting plate. An adjustment mechanism is provided on the inner wall of the support plate. The adjustment mechanism includes a mounting groove and a slider. The mounting groove starts at the top of the support plate. The slider is provided on the inner wall of the mounting groove. A photosensitive sensor is installed on the top of the slider. Two locking blocks are slidably connected to the inner wall of the slider. A guide block is slidably connected to the inner wall of the slider. Pressing blocks are fixedly connected to both sides of the guide block. According to the position of different patterns, the slider and its top photosensitive sensor are installed in the corresponding position in the mounting groove. Then, the pressing block is pushed down, which drives the guide block to move down. The guide block pushes the two locking blocks to move in opposite directions through the inclined surface, so that the two locking blocks are locked into the mounting groove, thereby realizing the quick installation of the slider. When it is necessary to disassemble, the pressing block is pushed up. The number of sliders installed depends on the specific number of patterns on the new material fiber cloth. More sliders and their top photosensitive sensors can also be installed on different patterns on different fiber cloths at the same time. A flattening mechanism is provided at the bottom of the mounting plate; A cleaning mechanism is disposed on the inner wall of the housing.

[0007] In one or more embodiments of the present invention, the guide block contacts the locking block, a spring is fixedly connected between the two locking blocks, and the pressing block contacts the inner wall of the slider; During inspection, the roll moves the fabric to the inspection area. At this time, the lights are turned on and shine light downwards. The areas of the fiber fabric with patterns block more light than the areas without patterns. Therefore, the light intensity of the light sensor at the corresponding position of the pattern is used to determine whether the pattern is missing. This eliminates the need for tedious image editing and comparison or manual comparison, thus improving the defect detection efficiency of the new material fiber fabric.

[0008] In one or more embodiments of the present invention, the surface of the slider contacts the inner wall of the mounting groove, the surface of the locking block contacts the inner wall of the mounting groove, and the lower surface of the fabric contacts the top of the support plate. When changing to different patterned fiber cloths for testing, since the corresponding photosensitive sensors are already installed at the beginning, there is no need to stop the machine to edit the pattern for comparison. The device can continue to run directly, and the test can be completed simply by detecting the light intensity of the photosensitive sensor at the corresponding position.

[0009] In one or more embodiments of the present invention, the flattening mechanism includes a guide rod, a spring sleeved on the circumferential surface of the guide rod, a mounting frame fixedly connected to the bottom end of the guide rod, and a pressure roller rotatably connected to the inner wall of the bottom of the mounting frame.

[0010] In one or more embodiments of the present invention, the guide rod is slidably connected to the inner wall of the mounting plate, the two ends of the spring on the circumferential surface of the guide rod are respectively in contact with the top of the mounting frame and the bottom of the mounting plate, and the circumferential surface of the pressure roller is in contact with the upper surface of the fabric. During testing, the hydraulic cylinder is activated and moves the mounting plate downwards. The mounting plate moves the guide rod downwards, which in turn moves the mounting frame downwards. The mounting frame then moves the pressure roller downwards, which presses onto the fabric. The mounting plate continues to move downwards and compresses the spring. The pressure of the spring is used by the pressure roller to press the fabric onto the support plate, ensuring that the photosensitive sensor is in close contact with the fabric and thus guaranteeing the detection effect of the photosensitive sensor.

[0011] In one or more embodiments of the present invention, the cleaning mechanism includes a movable plate, two transmission plates are fixedly connected to both the front and rear sides of the movable plate, cams are fixedly connected to both ends of the drum, an air inlet frame is installed on the left inner wall of the outer shell, an air outlet frame is installed on the right inner wall of the outer shell, the air inlet frame is connected to a negative ion fan, and the air outlet frame is connected to an exhaust fan. After the fabric inspection is completed, the drum rotates and moves the fabric, causing the pattern to be inspected to move onto the support plate. During the drum's rotation, the cam rotates, and the cam pushes the transmission plate up and down through a protrusion. The transmission plate pushes the moving plate, which in turn drives the push plate to move back and forth. The push plate lifts the fabric, causing dust and fiber debris on the fabric surface to be thrown up. At the same time, the air inlet frame on the left side of the casing is connected to a negative ion fan, which blows air into the casing. The negative ion fan eliminates static electricity, preventing dust and fiber debris from being attracted to the fabric or lamps due to static electricity, thus affecting the light and leading to inaccurate inspection results.

[0012] In one or more embodiments of the present invention, the top of the transmission plate contacts the circumferential surface of the cam, the movable plate is slidably connected to the inner wall of the housing by a spring, and the movable plate is located below the support plate; The air outlet frame on the right side of the casing will connect to the exhaust fan and extract dust and fiber debris from the casing. This prevents dust and fiber debris from suspending between the fabric and the lamp, thus preventing light scattering and improving detection accuracy.

[0013] In one or more embodiments of the present invention, the clearing mechanism further includes a limiting rod, the limiting rod being slidably connected to the inner wall of the support plate, and two push plates being fixedly connected to the top of the movable plate; During testing, the drum stops and the mounting plate moves down. The mounting plate pushes the limit rod down, which in turn moves the moving plate down and compresses the spring. The moving plate then moves the push plate down, causing it to retract into the support plate and no longer contact the fabric. This ensures that even if the protrusion of the cam does not contact the transmission plate after it rotates, the moving plate remains at the bottom. After testing, the mounting plate moves up to reset, and the compressed spring moves the moving plate up, allowing the transmission plate to re-engage with the cam.

[0014] In one or more embodiments of the present invention, the push plate is slidably connected to the inner wall of the support plate, the bottom end of the limiting rod is fixedly connected to the side of the moving plate, and the top end of the limiting rod is located on the movement trajectory of the mounting plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Before testing, the sliders and their top photosensitive sensors are installed in the corresponding positions in the mounting slot according to the location of different patterns. More sliders and their top photosensitive sensors can be installed simultaneously for different patterns on different fiber fabrics. During testing, the roll will move the fabric to the testing area. At this time, the lamp will be turned on and shine light downwards. The areas of the fiber fabric with patterns will block more light than the areas without patterns. Therefore, the light intensity of the photosensitive sensor at the corresponding position of the pattern is used to determine whether the pattern is missing. There is no need for tedious image editing and comparison or manual comparison, which improves the defect detection efficiency of new material fiber fabrics. At the same time, when changing to fiber fabrics with different patterns for testing, since the photosensitive sensors at the corresponding positions are installed at the beginning, there is no need to stop the machine to edit the pattern for comparison. The device can continue to run directly, and the detection can be completed by simply detecting the light intensity of the photosensitive sensor at the corresponding position.

[0016] 2. During testing, the hydraulic cylinder starts and moves the mounting plate downward. The mounting plate moves the guide rod downward, the guide rod moves the mounting frame downward, the mounting frame moves the pressure roller downward, and the pressure roller presses onto the fabric. Then the mounting plate continues to move downward and compresses the spring. The pressure of the spring is used by the pressure roller to press onto the fabric, so that the fabric is tightly attached to the support plate, and the photosensitive sensor is in tight contact with the fabric to ensure the detection effect of the photosensitive sensor.

[0017] 3. After the fabric inspection is completed, the moving plate drives the push plate to move back and forth. The push plate lifts the fabric, causing dust and fiber debris on the fabric surface to be stirred up. At the same time, the air inlet frame on the left side of the casing will be connected to the negative ion fan and blow air into the casing. The negative ion fan can eliminate static electricity and prevent dust and fiber debris from being attracted to the fabric or lamps due to static electricity, which would affect the light illumination and lead to inaccurate test results. The air outlet frame on the right side of the casing will be connected to the exhaust fan and extract the dust and fiber debris from the casing. This can prevent dust and fiber debris from being suspended between the fabric and lamps, thus preventing light scattering and improving the test accuracy.

[0018] 4. During testing, the drum will stop and the mounting plate will move downwards. The mounting plate will push the limit rod downwards, which in turn will move the moving plate downwards and compress the spring. The moving plate will then move the push plate downwards, causing it to retract into the support plate and no longer contact the fabric. This ensures that even if the protrusion of the cam does not contact the transmission plate after it rotates, the moving plate will still be at the bottom. After the test is completed, the mounting plate will move upwards to reset, and the compressed spring will move the moving plate upwards, allowing the transmission plate to re-contact the cam.

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figure 1-7 As shown, one embodiment of the present invention is: a defect detection device for a new material fiber cloth, comprising: The outer shell 1 has an openable rotating door installed at the front. A support plate 2 is fixedly installed on the inner wall of the outer shell 1. A roller 3 is rotatably connected to the inner wall of the support plate 2 via a connecting rod. Fabric 4 is wound around the circumference of the roller 3. Irradiation mechanism 5 is located on the top of housing 1. Irradiation mechanism 5 includes hydraulic cylinder 51. The output end of hydraulic cylinder 51 is fixedly mounted with mounting plate 52. A lamp 53 is mounted on the inner wall of the bottom of mounting plate 52. Adjustment mechanism 6 is set on the inner wall of support plate 2. Adjustment mechanism 6 includes mounting groove 61 and slider 62. Mounting groove 61 starts at the top of support plate 2. Slider 62 is set on the inner wall of mounting groove 61. Photosensitive sensor 63 is installed on the top of slider 62. Two locking blocks 64 are slidably connected to the inner wall of slider 62. Guide block 65 is slidably connected to the inner wall of slider 62. Pressing block 66 is fixedly connected to both the left and right sides of guide block 65. According to the position of different patterns, the slider 62 and the photosensitive sensor 63 on its top are installed in the corresponding position in the mounting groove 61, so that more sliders 62 and the photosensitive sensor 63 on its top can be installed at the same time for different patterns on different fiber cloths. Flattening mechanism 7 is located at the bottom of mounting plate 52; Cleaning mechanism 8 is disposed on the inner wall of housing 1; During inspection, the roll 3 moves the fabric 4 to the inspection area. At this time, the lamp 53 is turned on and shines light downwards. The areas with patterns on the fiber fabric block more light than the areas without patterns. Therefore, the light intensity of the light sensor 63 at the corresponding position of the pattern is used to determine whether the pattern is missing. This eliminates the need for tedious image editing and comparison or manual comparison, thus improving the defect detection efficiency of the new material fiber fabric.

[0023] The guide block 65 contacts the locking block 64, and a spring is fixedly connected between the two locking blocks 64. The pressing block 66 contacts the inner wall of the slider 62.

[0024] The surface of slider 62 contacts the inner wall of mounting groove 61, the surface of block 64 contacts the inner wall of mounting groove 61, and the lower surface of fabric 4 contacts the top of support plate 2. When changing to different patterned fiber cloths for testing, since the corresponding photosensitive sensor 63 is already installed at the beginning, there is no need to stop the machine to edit the pattern for comparison. The device can continue to run directly, and the test can be completed by simply detecting the light intensity of the corresponding photosensitive sensor 63.

[0025] The flattening mechanism 7 includes a guide rod 71, a spring is sleeved on the circumferential surface of the guide rod 71, a mounting frame 72 is fixedly connected to the bottom end of the guide rod 71, and a pressure roller 73 is rotatably connected to the inner wall of the bottom of the mounting frame 72. Hydraulic cylinder 51 starts and drives mounting plate 52 to move down. Mounting plate 52 drives guide rod 71 to move down. Guide rod 71 drives mounting frame 72 to move down. Mounting frame 72 drives pressure roller 73 to move down. Pressure roller 73 presses onto fabric 4. Then mounting plate 52 continues to move down and compresses spring. The pressure of spring is used by pressure roller 73 to press onto fabric 4, so that fabric 4 is in close contact with support plate 2, so that photosensitive sensor 63 is in tight contact with fabric 4, to ensure the detection effect of photosensitive sensor 63.

[0026] The guide rod 71 is slidably connected to the inner wall of the mounting plate 52. The two ends of the spring on the circumferential surface of the guide rod 71 are in contact with the top of the mounting frame 72 and the bottom of the mounting plate 52, respectively. The circumferential surface of the pressure roller 73 is in contact with the upper surface of the fabric 4.

[0027] Working principle: Before detection, according to the position of different patterns, the slider 62 and its top photosensitive sensor 63 are installed in the corresponding position in the mounting groove 61. Then, the pressing block 66 is pushed down, which drives the guide block 65 down. The guide block 65 pushes the two locking blocks 64 to move in opposite directions through the inclined surface, so that the two locking blocks 64 are locked into the mounting groove 61, thereby realizing the quick installation of the slider 62. When it is necessary to disassemble, the pressing block 66 is pushed up. The number of sliders installed depends on the specific number of patterns on the new material fiber cloth. More sliders 62 and their top photosensitive sensors 63 can also be installed simultaneously on different patterns on different fiber cloths. During detection, the roll 3 will drive the cloth... Material 4 is moved to the detection area. At this time, the lamp 53 is turned on and shines light downwards. The areas with patterns on the fiber cloth will block more light than the areas without patterns. Therefore, the light intensity of the photosensitive sensor 63 at the corresponding position of the pattern is used to determine whether the pattern is missing. There is no need for tedious image editing and comparison or manual comparison, which improves the defect detection efficiency of the new material fiber cloth. At the same time, when changing to fiber cloth with different patterns for detection, since the photosensitive sensor 63 at the corresponding position is installed at the beginning, there is no need to stop the machine to edit the pattern for comparison. The device can continue to run directly. It is only necessary to detect the light intensity of the photosensitive sensor 63 at the corresponding position to complete the detection. During testing, hydraulic cylinder 51 is activated and drives mounting plate 52 to move downward. Mounting plate 52 drives guide rod 71 to move downward, guide rod 71 drives mounting frame 72 to move downward, mounting frame 72 drives pressure roller 73 to move downward, and pressure roller 73 presses onto fabric 4. Then mounting plate 52 continues to move downward and compresses spring. The pressure of spring is used by pressure roller 73 to press onto fabric 4, so that fabric 4 is tightly attached to support plate 2, so that photosensitive sensor 63 is in tight contact with fabric 4, to ensure the detection effect of photosensitive sensor 63.

[0028] like Figure 1-7 As shown, based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 8 includes a movable plate 81, two transmission plates 82 are fixedly connected to both the front and rear sides of the movable plate 81, cams 83 are fixedly connected to both ends of the drum 3, an air inlet frame is installed on the left inner wall of the outer shell 1, an air outlet frame is installed on the right inner wall of the outer shell 1, the air inlet frame is connected to the negative ion fan, and the air outlet frame is connected to the exhaust fan. After the fabric 4 is tested, the moving plate 81 drives the push plate 85 to move back and forth. The push plate 85 lifts the fabric 4, causing the dust and fiber debris on the surface of the fabric 4 to be lifted up. At the same time, the air inlet frame on the left side of the outer shell 1 will be connected to the negative ion fan and blow air into the outer shell 1. The negative ion fan can eliminate static electricity and prevent dust and fiber debris from being attracted to the fabric 4 or the lamp 53 due to static electricity, which would affect the illumination of the light and thus lead to inaccurate test results.

[0029] The top of the transmission plate 82 contacts the circumferential surface of the cam 83, and the moving plate 81 is slidably connected to the inner wall of the housing 1 by a spring. The moving plate 81 is located below the support plate 2. The air outlet frame on the right side of the outer casing 1 will connect to the exhaust fan and extract the dust and fiber debris from the outer casing 1. This can prevent the dust and fiber debris from suspending between the fabric 4 and the lamp 53, thus preventing light scattering and improving detection accuracy.

[0030] The clearing mechanism 8 also includes a limiting rod 84, which is slidably connected to the inner wall of the support plate 2, and two push plates 85 are fixedly connected to the top of the moving plate 81. During the inspection, the roll 3 will stop and the mounting plate 52 will move down. The mounting plate 52 will push the limit rod 84 down, and the limit rod 84 will drive the moving plate 81 down and compress the spring. The moving plate 81 will drive the push plate 85 down, so that the push plate 85 retracts into the support plate 2 and no longer contacts the fabric 4. This ensures that even if the protrusion of the cam 83 does not contact the transmission plate 82 after the cam 83 rotates, the moving plate 81 will still be at the bottom. When the inspection is completed, the mounting plate 52 will move up and reset, and the compressed spring will drive the moving plate 81 up and make the transmission plate 82 contact the cam 83 again.

[0031] The push plate 85 is slidably connected to the inner wall of the support plate 2, the bottom end of the limiting rod 84 is fixedly connected to the side of the moving plate 81, and the top end of the limiting rod 84 is located on the movement trajectory of the mounting plate 52.

[0032] Working principle: After the fabric 4 is inspected, the drum 3 rotates and moves the fabric 4, causing the pattern to be inspected on the fabric 4 to move onto the support plate 2. During the rotation of the drum 3, the cam 83 rotates, and the cam 83 pushes the transmission plate 82 up and down through the protrusion. The transmission plate 82 pushes the moving plate 81 to move, and the moving plate 81 drives the push plate 85 to move back and forth. The push plate 85 lifts the fabric 4, causing dust and fiber debris on the surface of the fabric 4 to be lifted up. At the same time, the air inlet frame on the left side of the outer casing 1 will be connected to the negative ion fan and blow air into the outer casing 1. The negative ion fan can eliminate static electricity and prevent dust and fiber debris from being attracted to the fabric 4 or the lamp 53 due to static electricity, which would affect the illumination of the light and thus lead to inaccurate inspection results. The air outlet frame on the right side of the outer casing 1 will be connected to the negative ion fan. The exhaust fan removes dust and fiber debris from the outer casing 1, preventing them from suspending between the fabric 4 and the lamp 53, thus preventing light scattering and improving detection accuracy. During detection, the roller 3 stops and the mounting plate 52 moves downward. The mounting plate 52 pushes the limit rod 84 downward, which in turn moves the moving plate 81 downward and compresses the spring. The moving plate 81 then moves the push plate 85 downward, causing it to retract into the support plate 2 and no longer contact the fabric 4. This ensures that even if the protrusion of the cam 83 does not contact the transmission plate 82 after rotation, the moving plate 81 remains at the bottom. After detection, the mounting plate 52 moves upward to reset, and the compressed spring moves the moving plate 81 upward, allowing the transmission plate 82 to re-contact the cam 83.
