Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a light inspection device for the appearance of high-performance fiber three-dimensional fabrics. Background Technology

[0002] When high-performance fiber fabrics are composited, gaps exist between the fabric structures, creating a permeable surface. Large gaps can lead to uneven flow of mixed gases, resulting in uneven gas deposition. This can cause density inconsistencies during the bonding process between the fabric and the matrix, ultimately affecting the composite's lifespan. Therefore, after the 3D fabric is formed, its overall appearance, yarn uniformity, and the presence of permeable gaps in the thickness direction need to be inspected and technically addressed.

[0003] However, carbon fiber and silicon carbide fiber are special black materials with poor optical properties and poor light transmission. When the fiber undergoes surface processing and the gloss of the fiber surface is high enough, the angle of incident light and the angle of human eye line of sight will also produce reflection. It is necessary to select appropriate lighting to refract the fabric woven from such fibers.

[0004] Meanwhile, existing fabric inspection devices are only suitable for single-layer fabrics. For example, specialized testing equipment for relatively large and long fabrics such as cotton, wool, and chemical fibers, such as the utility model patent CN221765291U, suffers from several problems. When multiple lampshades illuminate three-dimensional fabrics, the different angles of light emission and reception cause localized surface reflections and localized darkening. Furthermore, the angle of the inspection table cannot be adjusted, the light intensity on the inspection table is uniform, and the light source area is fixed, making it unsuitable for addressing the differences in size, thickness, shape, and the angle of incidence of three-dimensional fabrics by different personnel. Moreover, the light intensity of existing inspection tables is not high enough to penetrate three-dimensional fabrics woven from such materials.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide a convenient, fast, reliable, and low-cost high-performance fiber three-dimensional fabric appearance light inspection device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] A light inspection device for the appearance of high-performance fiber three-dimensional fabrics includes a housing, a workbench, and a first drive mechanism. The housing includes a first side plate, a second side plate, a third side plate, and a fourth side plate that are erected in sequence. The first side plate, the second side plate, the third side plate, and the fourth side plate form an accommodating space for placing the workbench and the first drive mechanism. The orientation of the first side plate is defined as front, and the orientation of the third side plate is defined as rear.

[0009] The workbench is hinged at the top of the front side to the top of the first side plate, and at the bottom of the rear side to the first drive mechanism. The other end of the first drive mechanism is hinged to the bottom of the first side plate. The first drive mechanism is located at the bottom of the workbench and is used to drive the rear end of the workbench to rotate around the front end and lift it upward.

The support rod group includes at least one set of X-shaped brackets with their upper and lower ends respectively located between the upper support member and the lower support member.

[0013] Furthermore, the X-shaped bracket includes a first support rod and a second support rod, which are arranged intersectingly and hinged together in the middle by a hinge pin. The opening and closing drive unit includes a fixed end and a movable end, which are respectively connected to the first support rod and the second support rod, so as to drive the X-shaped bracket to open or close by extending and retracting the movable end.

[0014] Furthermore, the upper support member and the lower support member are provided with at least two sets of sliding grooves extending along their length direction and for sliding connection of the end of the first support rod and / or the end of the second support rod.

[0015] At least two sets of the sliding grooves are provided on the upper support member, or at least two sets of the sliding grooves are provided on the lower support member, or at least one set of the sliding grooves is provided on the upper support member and at least one set of the sliding grooves is provided on the lower support member.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 6

[0030] The appearance light inspection device for high-performance fiber three-dimensional fabrics includes a housing 1, a workbench 2, and a first drive mechanism. The housing 1 includes a first side plate 11, a second side plate, a third side plate 12, and a fourth side plate that are erected in sequence. The first side plate 11, the second side plate, the third side plate 12, and the fourth side plate form an accommodating space 13 for placing the workbench 2 and the first drive mechanism.

[0031] For ease of description, the orientation of the first side panel 11 is defined as front, and the orientation of the third side panel 12 is defined as rear.

[0032] The worktable 2 is hinged at the top of the front side to the top of the first side plate 11, and at the bottom of the rear side to the first drive mechanism. The other end of the first drive mechanism is hinged to the bottom of the first side plate 11. The first drive mechanism is located at the bottom of the worktable 2 and is used to drive the rear end of the worktable 2 to rotate around the front end and lift it upward. It is worth noting that in this embodiment, a hinge 31 is used to connect the worktable 2 and the first side plate 11. One side of the hinge 31 is fixed to the worktable 2, and the other side is fixed to the first side plate 11. The first drive mechanism drives the worktable 2 to rotate along the pivot of the hinge 31, thereby lifting the worktable 2.

[0033] Furthermore, the first driving mechanism includes at least one set of hydraulic rods 32. In this embodiment, three sets of hydraulic rods 32 are used, and the three sets of hydraulic rods 32 are evenly distributed at the bottom of the worktable 2. Setting more sets of hydraulic rods 32 can more smoothly lift the worktable 2. In use, the product to be inspected is placed on the worktable 2 for inspection. By driving the hydraulic rods 32, the tilt angle of the worktable 2 is adjusted from 0 to 60 degrees according to the operator's perspective, making it easier to detect surface texture defects or penetrating pores in the thickness direction of the three-dimensional fabric. This avoids fatigue and discomfort caused by the operator looking down for a long time and improves inspection efficiency.

[0034] Furthermore, the workbench 2 includes a housing 21 with an open top, a first light source 22 disposed at the opening, a translucent glass 23 disposed on the first light source 22, and a second driving mechanism disposed within the housing 21. One end of the second driving mechanism is fixedly disposed within the housing 21, and the other end is fixedly disposed with a support plate 24 for placing the first light source 22, so that the first light source 22 placed on the support plate 24 can be moved closer to or away from the translucent glass 23 by driving the second driving mechanism. It is worth noting that in this embodiment, the first light source 22 is a multi-LED high-intensity light source, providing sufficient light transmission to the translucent glass 23, and the light emission area can be controlled according to the size of the three-dimensional fabric. It is also worth noting that the first light source 22 is provided with multiple brightness intensity knobs, so that the brightness of the first light source 22 transmitted through the translucent glass 23 can be adjusted for inspecting three-dimensional fabrics of different thicknesses.

[0035] Furthermore, a lampshade 25, which is made of acrylic, is provided between the translucent glass 23 and the first light source 22. The translucent glass 23 is used for light transmission and placement of three-dimensional fabrics, while the acrylic lampshade 25 has excellent light transmission, which can effectively adjust the light and improve the diffuse reflection of the light, making the light more uniform and softer after passing through the acrylic lampshade 25, thus avoiding glare.

[0036] Furthermore, the second driving mechanism includes an upper support member 41 fixedly connected to the housing 21 and a lower support member 42 fixedly connected to the bearing plate 24, at least one support rod group disposed between the upper support member 41 and the lower support member 42, and a tensioning and opening driving unit for driving the support rod group to open and close. Preferably, this embodiment uses two sets of support rod groups (a first support rod group 431 and a second support rod group 432, respectively), which will be explained in detail below.

[0037] The first support rod group 431 and the second support rod group 432 both include at least one set of X-shaped brackets with their upper and lower ends located between the upper support member 41 and the lower support member 42, respectively. Preferably, this embodiment uses two sets of X-shaped brackets, namely the first X-shaped bracket 441 and the second X-shaped bracket 442.

[0038] Furthermore, both the first X-shaped bracket 441 and the second X-shaped bracket 442 include a first support rod 451 and a second support rod 452. The first support rod 451 and the second support rod 452 are arranged to cross each other and are hinged together in the middle by a hinge pin 453. The first X-shaped bracket 441 and the second X-shaped bracket 442 of the first support rod group 431 and the second support rod group 432 are hinged together by a hinge pin 453.

[0039] The first X-shaped bracket 441 and the second X-shaped bracket 44 of the first support rod assembly 431 are hinged together. The two upper first support rods 451 and the two lower second support rods 452 are connected by a movable linkage rod 461, and the two upper second support rods 452 and the two lower first support rods 451 are connected by a fixed linkage rod 462.

[0040] Furthermore, at least two sets of sliding grooves 47 extending along their length and slidably connected to the movable linkage rods 461 are provided on the upper support member 41 and the lower support member 42. The movable linkage rods 461 are slidably disposed in the corresponding sliding grooves 47, so that the two first support rods 451 disposed on the upper part can slide synchronously along the guide direction of the sliding grooves 47 disposed on the upper support member 41, and the two second support rods 452 disposed on the lower part can slide synchronously along the guide direction of the sliding grooves 47 disposed on the lower support member 42.

[0041] The opening and closing drive unit includes a fixed end 481 and a movable end 482. The fixed end 481 is fixedly connected to a fixed linkage rod 462, and the movable end 482 passes through another fixed linkage rod 462 and is movably connected to it. It is worth noting that the opening and closing drive unit in this embodiment is a threaded screw 48. The fixed linkage rod 462 movably connected to the screw 48 is threaded together, so that by rotating the screw 48, the fixed linkage rod 462 movably connected to the screw 48 moves closer to or further away from the other fixed linkage rod 462, thereby driving the X-shaped bracket to open or close. The opening and closing drive unit adjusts the height (closer or further away from the light-transmitting glass 23) of the first light source 22 mounted on the support plate 24, further adjusting the suitable light intensity.

[0042] Furthermore, two frames 5 are erected vertically at the top ends of the third side plate 12, each frame 5 being inverted L-shaped. A back plate 61 and a top plate 62 are disposed between the two frames 5. The back plate 61 is vertically erected, and the top plate 62 is horizontally positioned. A second light source 63 is disposed at the bottom of the top plate 62. The two ends of the top plate 62 are hinged to the two frames 5 by pins. A third drive mechanism is connected to the pins and drives the top plate 62 to rotate by rotating the pins. It is worth noting that the third drive mechanism in this embodiment is a tightening bolt 64. The tightening bolt 64 is used to loosen the tension between itself and the pin, thereby rotating the top plate 64 and the second light source 63 to the required angle. The tension is then tightened again. A large-size, high-intensity second light source 63 with an adjustable illumination angle is configured directly above the workbench 2 surface, forming a light source with a large luminous area and strong brightness. When adjusting the illumination angle for different areas of the three-dimensional fabric shape to inspect appearance and texture, it avoids missed detections and misjudgments caused by umbra and penumbra in the area due to small light source and single angle.

[0043] Furthermore, the bottom of the housing 1 is equipped with four rollers 7, which are located at the four corners of the housing 1, to facilitate the movement of the device.

[0044] Furthermore, the bottom of the housing 1 is provided with several support legs 8, which are movably mounted on the bottom of the housing 1. Each support leg 8 is a bolt support leg. When the device needs to be moved, the support legs 8 are adjusted so that their bottom surfaces are higher than the ground, and the device is moved by the rollers 7. When the device needs to be tested or fixed, the support legs 8 are adjusted so that they are level with the ground or their bottom surfaces are lower than the bottom surfaces of the rollers 7.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
