Description

Technical Field

[0001] This invention relates to the field of glass fiber needled mat testing technology, specifically to a device for testing the uniformity of fiber distribution in glass fiber needled mat. Background Technology

[0002] The uniformity of fiber distribution in fiberglass needle-punched felt is an important factor affecting its performance and application effect. When testing the uniformity of fiber distribution in fiberglass needle-punched felt, light irradiation is generally used. A high-precision camera is installed on the other side of the irradiated fiberglass needle-punched felt to capture images of the light passing through the felt. Each frame of the image captured by the camera is analyzed, and a series of uniformity indicators (such as gray-scale variance, spectrum analysis, density distribution map, etc.) are calculated through algorithms, and the pass rate is determined in real time.

[0003] Patent CN211043138U discloses a fabric transmittance testing device, relating to the field of fabric testing technology. This device includes an illumination chamber and a testing chamber. One end of the illumination chamber and the testing chamber are rotatably connected by a hinge, and the other end is movably engaged by a snap-fit ​​assembly. An illumination mechanism is fixedly connected to the bottom of the illumination chamber, and a lux meter is fixedly connected inside the testing chamber. A pressing assembly is movably engaged at the bottom of the left and right side walls of the testing chamber, and a locking strip is fixedly connected to the top of the left and right side walls of the illumination chamber. This fabric transmittance testing device connects the illumination chamber and the testing chamber via the snap-fit ​​assembly, and simultaneously provides locking strips and pressing assemblies at the contact points between the two chambers. Through the cooperation of the locking strips and pressing assemblies, the fabric to be tested is secured between the two chambers, ensuring complete isolation of the device from external light sources and improving the accuracy of the test data.

[0004] However, the above-mentioned device only uses a fixed light source to detect the uniformity of fiber distribution (transmittance), which is prone to having a small and one-sided detection range, thus affecting the subsequent detection results. At the same time, when detecting fiberglass needle-punched felt, the feeding of fiberglass needle-punched felt will cause short fiberglass fibers to float in the air. These short fiberglass fibers will affect the image of light penetrating the felt by the camera, thus affecting the detection results. Therefore, a fiber distribution uniformity detection device for fiberglass needle-punched felt is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for detecting the uniformity of fiber distribution in glass fiber needle-punched felt, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fiber distribution uniformity detection device for fiber-needled felt, comprising a box, a guide roller rotatably connected to the inner wall of the box, lower protective boxes installed on both the front and rear sides of the box, an upper protective box installed on the top of the box, an electric slide rail installed on the top of the inner wall of the box, a detection mechanism provided at the moving end of the electric slide rail, a fiber removal mechanism provided on the inner wall of the box, and a collection mechanism provided on the top of the box; The detection mechanism includes a high-precision camera, which is fixedly connected to the moving end of an electric slide rail. Upper sleeves are rotatably connected to both the front and rear sides of the high-precision camera via connecting rods. A transmission rod is slidably connected to the inner wall of the upper sleeve, and a fixing rod is rotatably connected to the inner wall of the housing. During the production of fiberglass needle-punched felt, fiber uniformity is detected as the conveyed fiberglass needle-punched felt passes through the housing. When the fiberglass needle-punched felt enters the housing, guide rollers guide it, and an illumination lamp illuminates it. The high-precision camera then detects the light passing through the fiberglass needle-punched felt. The device takes pictures, and the pictures are then analyzed by a computer connected to it. The computer analyzes each frame of the high-precision camera and calculates a series of uniformity indicators (such as gray-scale variance, spectrum analysis, density distribution map, etc.) through algorithms. It also judges in real time whether the fiber distribution on the fiberglass needle-punched felt is uniform. An illumination lamp is fixedly connected to the circumference of the fixed rod. An outer plate is fixedly connected to the inner wall of the box. An inner plate is slidably connected to the inner wall of the outer plate. A fixing strip is fixedly connected to the front of the inner plate. A lower sleeve is rotatably connected to the front of the fixing strip through a connecting rod. The outer and inner panels support the fiberglass needle-punched felt, preventing it from becoming suspended and loose within the chamber, which could affect the test results. Simultaneously, the swinging of the transmission rod moves the lower sleeve, which in turn moves the fixing bar via a connecting rod. The fixing bar moves the inner panel, which moves along with the swinging light, ensuring that the gap between the two inner panels is always large enough to allow the swinging light to pass through, while maintaining the support effect of the fiberglass needle-punched felt.

[0007] Preferably, the circumferential surface of the fixing rod is fixedly connected to the bottom end of the transmission rod, the fixing strip is slidably connected to the inner wall of the housing, the inner wall of the lower sleeve is slidably connected to the circumferential surface of the transmission rod, and the connecting rod between the high-precision camera and the upper sleeve is in contact with the inner wall of the housing. An electric slide rail drives a high-precision camera to move back and forth. The high-precision camera, via a connecting rod, drives an upper sleeve to move back and forth. The upper sleeve drives a transmission rod to swing back and forth along a fixed rod, while the upper sleeve slides on the transmission rod. The transmission rod drives the fixed rod to rotate in both directions, and the fixed rod drives the illumination lamp to swing back and forth. The light from the illumination lamp swings, increasing its contact area with the fiberglass needle-punched felt. Simultaneously, the high-precision camera moves along with the light and remains on the path of the light, allowing for illumination and detection of the fiberglass needle-punched felt at different angles, thus improving the detection effect of the device. The high-precision camera has an autofocus system, which ensures that it can automatically focus after displacement, preventing it from losing focus during light shooting and thus affecting its detection.

[0008] Preferably, the fiber removal mechanism includes a suction head, a flexible tube is fixedly connected to the suction head, and fixed plates are fixedly connected to both the front and rear sides of the suction head. A middle sleeve is rotatably connected to the front of the fixed plate via a connecting rod.

[0009] Preferably, a collection box is fixedly connected to the top of the box body, an exhaust fan is fixedly connected to the top of the collection box, and a filter plate is fixedly connected to the inner wall of the collection box; The exhaust fan is started and the suction head is driven by the hose to suck up the short fiberglass fibers floating above the fiberglass needle-punched felt. This prevents the short fiberglass fibers from staying in the light shooting range of the high-precision camera, which would affect the light shooting effect of the high-precision camera, and thus affect the subsequent computer image analysis results and the final detection results.

[0010] Preferably, the fixing plate is slidably connected to the inner wall of the box, the inner wall of the middle sleeve is slidably connected to the circumferential surface of the transmission rod, and the end of the hose away from the suction head is fixedly connected to the bottom of the collection box; The transmission rod drives the middle sleeve to move back and forth, the middle sleeve drives the fixed plate to move back and forth, and the fixed plate drives the suction head to move back and forth. The suction head can move along with the swing of the light, increasing the suction range of the suction head, while ensuring that the suction head can pick up all the short fiberglass fibers within the light-illuminated range.

[0011] Preferably, the collection mechanism includes a collection box, a chuck is threadedly connected to the inner wall of the rear of the collection box, a rotating rod is rotatably connected to the front of the chuck, a turntable is slidably connected to the circumferential surface of the rotating rod via a spline, and a gear is fixedly connected to the front of the turntable.

[0012] Preferably, the circumferential surface of the turntable is rotatably connected to the inner wall of the front part of the collection box, and multiple hook rods are fixedly connected to the circumferential surface of the rotating rod, and the collection box is fixedly connected to the collection container.

[0013] Preferably, the collecting mechanism further includes a top rod, with push rods fixedly connected to both sides of the top rod, a rack fixedly connected to the circumferential surface of the push rod, and a push plate fixedly connected to the end of the push rod away from the top rod; The collected fiberglass lint enters the collection box, where it is blocked by a filter plate. As the high-precision camera reciprocates, it moves a push rod, which in turn moves a pusher rod, which in turn moves a pusher plate. The pusher plate pushes the fiberglass lint blocked by the filter plate into the collection box. Simultaneously, the pusher moves a rack, which in turn rotates a gear, which in turn rotates a turntable. The turntable, via a spline, rotates a rotating rod, which, through a surface hook, rolls up the fiberglass lint in the collection box for easy cleaning later.

[0014] Preferably, the top of the push plate contacts the bottom of the filter plate, the bottom of the push plate contacts the inner wall of the collection box, and the circumferential surface of the push rod is slidably connected to the inner wall of the collection box.

[0015] Preferably, the top rod contacts the inner wall of the top of the box, the circumferential surface of the gear meshes with the top of the rack, and the rack is slidably connected to the front of the collection box; When cleaning fiberglass lint, rotate the chuck in the opposite direction to allow it to disengage from the collection box via threads. Then remove the chuck, which will drive the rotating rod to remove the collection box. Clean the surface of the collection box of fiberglass lint. Then, put the rotating rod back into the collection box and insert it into the inner wall of the turntable via splines, allowing the turntable to rotate the rod. Finally, screw the chuck back into the collection box via threads. This allows for quick installation and removal of the rotating rod, facilitating the cleaning of the surface fiberglass lint.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This fiber distribution uniformity detection device for fiberglass needle-punched felt uses a fixed rod to drive an illumination lamp to swing back and forth. The light from the illumination lamp swings, increasing its contact area with the fiberglass needle-punched felt. At the same time, a high-precision camera moves along with it and stays on the path of the light. This allows the device to illuminate and detect the fiberglass needle-punched felt at different angles, improving the detection effect. The high-precision camera has an autofocus system, which ensures that it can automatically focus after displacement, preventing it from losing focus during light shooting and thus affecting the detection.

[0017] 2. The fiber distribution uniformity testing device for fiberglass needled felt has an outer plate and an inner plate that can support the fiberglass needled felt, preventing it from being suspended in the box and loosening, which would affect the test results. At the same time, when the transmission rod swings, it will drive the lower sleeve to move together. The lower sleeve drives the fixing bar to move back and forth through the connecting rod. The fixing bar drives the inner plate to move. The inner plate will move together with the swing of the light, ensuring that the gap between the two inner plates can always allow the swinging light to pass through, while ensuring the support effect of the fiberglass needled felt.

[0018] 3. The fiber distribution uniformity detection device for fiberglass needle-punched felt uses an exhaust fan that drives a suction head via a hose to pick up the short fiberglass fibers floating above the fiberglass needle-punched felt. This prevents the short fiberglass fibers from remaining within the light-emitting range of the high-precision camera, which would affect the camera's light-emitting performance and lead to inaccurate subsequent computer image analysis and final detection results. Simultaneously, the suction head can move with the movement of the light, increasing its suction range and ensuring that the suction head picks up all the short fiberglass fibers within the light-emitting range.

[0019] 4. The fiber distribution uniformity detection device for fiberglass needle-punched felt has a pusher plate that can push the short fiberglass fibers blocked by the filter plate into the collection box. At the same time, the rotating rod rolls up the short fiberglass fibers in the collection box through the surface hook rod, which facilitates subsequent cleaning. The quick-release structure of the chuck allows for quick installation and removal of the rotating rod, which facilitates the cleaning of the short fiberglass fibers on its surface.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-7 One embodiment of the present invention is: a fiber distribution uniformity detection device for fiber-needled felt, comprising a box 1, a guide roller 2 rotatably connected to the inner wall of the box 1, a lower protective box 3 installed on both the front and rear sides of the box 1, an upper protective box 4 installed on the top of the box 1, an electric slide rail 5 installed on the top of the inner wall of the box 1, a detection mechanism 6 provided at the moving end of the electric slide rail 5, a fiber removal mechanism 7 provided on the inner wall of the box 1, and a collection mechanism 8 provided on the top of the box 1. The testing mechanism 6 includes a high-precision camera 61, which has an autofocus system to ensure continuous autofocus after displacement, preventing defocusing during light exposure and affecting testing. The high-precision camera 61 is fixedly connected to the moving end of the electric slide rail 5. Upper sleeves 62 are rotatably connected to both the front and rear sides of the high-precision camera 61 via connecting rods. A transmission rod 63 is slidably connected to the inner wall of the upper sleeve 62. A fixing rod 64 is rotatably connected to the inner wall of the housing 1. An illumination lamp 65 is fixedly connected to the circumference of the fixing rod 64. The inner wall of the housing 1 is fixed... An outer plate 66 is connected to the inner wall of the outer plate 66, and an inner plate 67 is slidably connected to the inner wall of the outer plate 66. A fixing strip 69 is fixedly connected to the front of the inner plate 67. A lower sleeve 68 is rotatably connected to the front of the fixing strip 69 via a connecting rod. When the transmission rod 63 swings, it will drive the lower sleeve 68 to move together. The lower sleeve 68 drives the fixing strip 69 to move back and forth via the connecting rod. The fixing strip 69 drives the inner plate 67 to move. The inner plate 67 will move together with the swing of the light to ensure that the gap between the two inner plates 67 can always allow the swinging light to pass through, while ensuring the support effect of the fiberglass needle-punched felt.

[0024] The circumferential surface of the fixed rod 64 is fixedly connected to the bottom end of the transmission rod 63. The fixed strip 69 is slidably connected to the inner wall of the housing 1. The inner wall of the lower sleeve 68 is slidably connected to the circumferential surface of the transmission rod 63. The connecting rod between the high-precision camera 61 and the upper sleeve 62 is in contact with the inner wall of the housing 1. The outer plate 66 and the inner plate 67 can support the fiberglass needle-punched felt to prevent the fiberglass needle-punched felt from being suspended in the housing 1 and thus loosening, which would affect the test results.

[0025] Working Principle: During the production of fiberglass needle-punched felt, fiber uniformity is detected as the conveyed fiberglass needle-punched felt passes through box 1. When the fiberglass needle-punched felt enters box 1, guide roller 2 guides it, while illumination lamp 65 illuminates it. A high-precision camera 61 captures the light passing through the felt. The captured images are then analyzed by a computer connected to the device. The computer analyzes each frame captured by the high-precision camera 61, calculating a series of uniformity indicators such as grayscale variance, spectral analysis, and density distribution map, and determines in real time whether the fiber distribution on the fiberglass needle-punched felt is uniform. An electric slide rail 5 drives the high-precision camera 61 to move back and forth. The high-precision camera 61 drives the upper sleeve 62 to move back and forth via a connecting rod. The upper sleeve 62 drives the transmission rod 63 to swing back and forth along the fixed rod 64. The upper sleeve 62 slides on the transmission rod 63, which drives the fixed rod 64 to swing back and forth. The fixed rod 64 drives the illumination lamp 65 to swing back and forth. The light irradiated by the illumination lamp 65 swings to increase its contact area with the fiberglass needle-punched felt. At the same time, the high-precision camera 61 also moves together and stays on the illumination trajectory of the light. This allows the fiberglass needle-punched felt to be irradiated and detected at different angles, improving the detection effect of the device. The high-precision camera 61 has an autofocus system, which allows it to automatically focus after displacement, preventing it from losing focus during light shooting and affecting its detection. The outer plate 66 and the inner plate 67 can support the fiberglass needle-punched felt, preventing it from being suspended in the housing 1 and becoming loose, which would affect the test results. At the same time, when the transmission rod 63 swings, it will drive the lower sleeve 68 to move together. The lower sleeve 68 drives the fixing bar 69 to move back and forth through the connecting rod. The fixing bar 69 drives the inner plate 67 to move. The inner plate 67 will move together with the swing of the light, ensuring that the gap between the two inner plates 67 can always allow the swinging light to pass through, while ensuring the support effect of the fiberglass needle-punched felt.

[0026] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the fiber removal mechanism 7 includes a suction head 71, a flexible tube 74 is fixedly connected to the suction head 71, and a fixing plate 72 is fixedly connected to both the front and rear sides of the suction head 71. The front part of the fixing plate 72 is rotatably connected to a middle sleeve 73 through a connecting rod. The suction head 71 can move together with the swing of the light, thereby increasing the suction range of the suction head 71, and at the same time ensuring that the suction head 71 can suck up all the glass fiber short fibers within the light irradiation range.

[0027] A collection box 75 is fixedly connected to the top of the box 1, an exhaust fan 77 is fixedly connected to the top of the collection box 75, and a filter plate 76 is fixedly connected to the inner wall of the collection box 75.

[0028] The fixed plate 72 is slidably connected to the inner wall of the box 1, the inner wall of the middle sleeve 73 is slidably connected to the circumferential surface of the transmission rod 63, and the end of the hose 74 away from the suction head 71 is fixedly connected to the bottom of the collection box 75. The exhaust fan 77 is started and drives the suction head 71 through the hose 74 to suck up the short fiberglass fibers floating above the fiberglass needle-punched felt, so as to prevent the short fiberglass fibers from staying in the light shooting range of the high-precision camera 61, thereby affecting the light shooting effect of the high-precision camera 61, resulting in inaccurate image analysis results of the subsequent computer and the final detection results.

[0029] The collection mechanism 8 includes a collection box 81. A chuck 82 is threadedly connected to the inner wall of the rear of the collection box 81. A rotating rod 83 is rotatably connected to the front of the chuck 82. A turntable 84 is slidably connected to the circumferential surface of the rotating rod 83 via a spline. A gear 85 is fixedly connected to the front of the turntable 84. The quick-release structure of the chuck 82 allows for the quick installation and removal of the rotating rod 83, facilitating the cleaning of the short fiberglass fibers on its surface. The spline setting allows the rotating rod 83 and the turntable 84 to slide relative to each other and separate. It also allows the rotating rod 83 to rotate together with the turntable 84 when it rotates.

[0030] The circumferential surface of the turntable 84 is rotatably connected to the inner wall of the front of the collection box 81. Multiple hooks are fixedly connected to the circumferential surface of the rotating rod 83. The collection box 81 is fixedly connected to the collection box 75. The rotating rod 83 rolls up the fiberglass lint that enters the collection box 81 through the surface hooks, which facilitates subsequent cleaning.

[0031] The collecting mechanism 8 also includes a push rod 88, with push rods 87 fixedly connected to both sides of the push rod 88, a rack 86 fixedly connected to the circumferential surface of the push rod 87, and a push plate 89 fixedly connected to the end of the push rod 87 away from the push rod 88.

[0032] The top of the push plate 89 contacts the bottom of the filter plate 76, the bottom of the push plate 89 contacts the inner wall of the collection box 75, and the circumferential surface of the push rod 87 is slidably connected to the inner wall of the collection box 75. The push plate 89 can push the glass fiber lint blocked by the filter plate 76 into the collection box 81.

[0033] The top rod 88 contacts the inner wall of the top of the box 1, the circumferential surface of the gear 85 meshes with the top of the rack 86, and the rack 86 is slidably connected to the front of the collection box 75.

[0034] Working principle: The exhaust fan 77 is started and drives the suction head 71 through the hose 74 to pick up the short fiberglass fibers floating above the fiberglass needle-punched felt, preventing the short fiberglass fibers from staying in the light shooting range of the high-precision camera 61, thus affecting the light shooting effect of the high-precision camera 61, and consequently affecting the image analysis results of the computer and the final detection results. The transmission rod 63 drives the middle sleeve 73 to move back and forth, the middle sleeve 73 drives the fixing plate 72 to move back and forth, and the fixing plate 72 drives the suction head 71 to move back and forth. The suction head 71 can move with the swing of the light, increasing the suction range of the suction head 71, while ensuring that the suction head 71 picks up all the short fiberglass fibers in the light-illuminated range. The collected fiberglass lint enters the collection box 75, where it is blocked by the filter plate 76. Simultaneously, the reciprocating movement of the high-precision camera 61 moves the push rod 88, which in turn moves the push rod 87, which in turn moves the push plate 89. The push plate 89 pushes the fiberglass lint blocked by the filter plate 76 into the collection box 81. At the same time, the push rod 87 moves the rack 86, which in turn rotates the gear 85. The gear 85 rotates the turntable 84, which in turn rotates the rotating rod 83 via a spline. The rotating rod 83 then uses a surface hook to push the fiberglass lint into the collection box 81. Roll it up for easy cleaning later. When it is necessary to clean the fiberglass lint, rotate the chuck 82 in the opposite direction to rotate it, so that the chuck 82 is disengaged from the collection box 81 by the thread. Then remove the chuck 82, and the chuck 82 drives the rotating rod 83 to remove the collection box 81. Then clean the fiberglass lint on its surface, and then put the rotating rod 83 back into the collection box 81. Insert the rotating rod 83 into the inner wall of the turntable 84 through the spline, so that the turntable 84 can drive the rotating rod 83 to rotate. Then turn the chuck 82 back into the collection box 81 by the thread. This allows for quick installation and removal of the rotating rod 83, which is convenient for cleaning the fiberglass lint on its surface.
