Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to a fiber filament surface inspection mechanism. Background Technology

[0002] During the production of fiber yarn, defects such as broken or bundled yarns frequently occur on the yarn surface due to process and equipment limitations, affecting product quality. Existing inspection methods typically employ visual inspection mechanisms to examine the fiber surface to improve product yield. However, these mechanisms can only inspect one side of the fiber at a time. When inspecting the other side, a rotating mechanism is required to flip the fiber before re-inspection, which is cumbersome and can easily cause fiber twisting, impacting product quality. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a fiber surface inspection mechanism that can achieve comprehensive inspection of the fiber surface in a single inspection, and also avoid the problem of fiber twisting and deformation during the inspection process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a fiber surface detection mechanism, comprising...

[0005] Machine tool;

[0006] A visual inspection component is located on the machine platform and includes a detection camera and a mirror surface for use; the mirror surface is located directly below the detection camera and includes a mirror groove with an upward opening;

[0007] The material transfer assembly, located on the machine platform, includes a first clamping member and a second clamping member arranged along the length of the fiber filament on both sides of the mirror surface. The first clamping member and the second clamping member are used to clamp the two ends of the fiber filament so that the fiber filament is suspended in the prism groove.

[0008] The beneficial effects of this novel fiber surface inspection mechanism are as follows:

[0009] In use, the first and second clamping parts of the transfer assembly first clamp the two ends of the fiber to be tested, and suspend the fiber in the prism groove. At this time, the bottom and side surfaces of the fiber can be captured by the detection camera under the reflection of the prism groove. When the detection camera is started, it can simultaneously acquire photos of the top, side and bottom surfaces of the fiber, thereby realizing a comprehensive inspection of the fiber surface.

[0010] Compared with the prior art, this application achieves comprehensive detection of the fiber surface by cooperating with the detection camera and the mirror surface, and avoids the rotation of the fiber during the detection process, thereby avoiding the problem of fiber twisting and deformation caused by different rotation amplitudes at both ends of the fiber.

[0011] Furthermore, the mirror surface includes a mounting base and a bottom prism and side prisms located on the mounting base. The upper surface of the bottom prism is flat. Two side prisms are provided and symmetrically arranged on the upper surface of the bottom prism. The bottom prism and side prisms together form the mirror groove with an inverted trapezoidal structure. Through the cooperation of the bottom prism and the two side prisms, the bottom and side surfaces of the fiber can be reflected, thereby enabling the inspection camera to fully inspect the surface of the fiber in a single inspection.

[0012] Furthermore, the side prisms are right-angled triangular prisms, and when they are installed, the inclined planes of the two right-angled triangular prisms are set opposite each other.

[0013] Furthermore, the bottom prism is provided with a protrusion located between the two side prisms. The protrusion supports the suspended fiber filaments, preventing them from falling directly onto the bottom prism.

[0014] Furthermore, the transfer assembly includes a sliding substrate that can move along the fiber length direction, the first clamping member and the second clamping member are both located on the sliding substrate, and the second clamping member can move along the sliding substrate in a direction closer to or away from the first clamping member.

[0015] Since the mirror surface can only reflect the fibers located within the mirror groove, the movement of the sliding substrate allows the first and second clamping members to move the fibers, enabling different portions of the fibers along their length to enter the mirror groove for detection. Furthermore, the movement of the second clamping member relative to the first clamping member accommodates fibers of varying lengths, and the movement of the second clamping member away from the first clamping member ensures the tension of the fibers.

[0016] Furthermore, the sliding substrate has grooves arranged along the length of the fiber filaments, and a mounting base plate for mounting the second clamping member is slidably disposed within the grooves. The movement of the second clamping member on the sliding substrate is achieved through the cooperation between the grooves and the mounting base plate.

[0017] Furthermore, both the first clamping member and the second clamping member include a clamping base plate, a fixed clamping arm, a movable clamping arm, and a driving member. The fixed clamping arm is fixedly connected to the clamping base plate. The movable clamping arm can move along the clamping base plate under the action of the driving member and clamp or release the fiber together with the fixed clamping arm.

[0018] Furthermore, both the fixed clamping arm and the movable clamping arm include cantilever arms arranged horizontally. A clamping rod is bent at the end of the cantilever arm away from the clamping substrate. When the movable clamping arm moves under the action of the driving member, the clamping rod of the movable clamping arm can move towards or away from the clamping rod of the fixed clamping arm. The cooperation of the cantilever arms and clamping rods ensures the clamping function of the fiber filaments while facilitating the adjustment of the positions of the first and second clamping members to make room for the vision inspection component.

[0019] Furthermore, the clamping rod has an elastic pad on the side facing the fiber filament to flexibly clamp the fiber filament, ensuring clamping force while avoiding damage to the surface of the fiber filament.

[0020] Furthermore, the visual inspection component also includes a stand and a linear module, and the inspection camera can move up and down along the stand under the action of the linear module. The linear module facilitates the adjustment of the inspection camera's height. Attached Figure Description

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Example

[0031] See appendix Figure 1-5 As shown, this utility model discloses a fiber surface inspection mechanism, comprising a machine base 1, a vision inspection component 2, and a transfer component 3. The vision inspection component 2 is located on the machine base 1 and includes a detection camera 21 and a mirror surface 22 for cooperative use. The mirror surface 22 is located directly below the detection camera 21 and includes an upward-opening mirror groove. The transfer component 3 is located on the machine base 1 and includes a first clamping member 31 and a second clamping member 32 arranged along the length of the fiber on both sides of the mirror surface 22. The first clamping member 31 and the second clamping member 32 are used to clamp the two ends of the fiber, allowing the fiber to suspend within the prism groove.

[0032] In use, the two ends of the fiber to be tested are first clamped by the first clamping member 31 and the second clamping member 32 of the transfer assembly 3, and the fiber is suspended in the prism groove. At this time, the bottom and side surfaces of the fiber can be photographed by the detection camera 21 under the reflection of the prism groove. When the detection camera 21 is started, the detection camera 21 can simultaneously acquire photos of the top, side and bottom surfaces of the fiber, thereby realizing a comprehensive inspection of the fiber surface.

[0033] For details, please see the appendix. Figure 3 As shown, the mirror surface 22 includes a mounting base 221 and a bottom prism 222 and side prisms 223 located on the mounting base 221. The bottom prism 222 is a planar prism, and its upper end face is a plane arranged in the horizontal direction. There are two side prisms 223, which are symmetrically arranged on the upper end face of the bottom prism 222. The bottom prism 222 and the two side prisms 223 together form a mirror groove.

[0034] Furthermore, the side prism 223 is a right-angled triangular prism. During installation, the inclined surfaces of the two right-angled triangular prisms are arranged opposite each other so that the mirror groove can present an inverted trapezoidal structure, so as to better reflect the bottom and side surfaces of the fiber filaments.

[0035] To prevent the fibers from sagging in the mirror groove, in some embodiments, a protrusion 224 is provided on the upper surface of the bottom prism 222, located between the two side prisms 223. The protrusion 224 also adopts a mirror design. By supporting the fibers with the protrusion 224, the fibers are prevented from sagging onto the bottom prism 222, ensuring that the fibers are always suspended in the mirror groove.

[0036] Since the mirror surface 22 and the detection camera 21 can only detect the fibers located within the mirror groove, the detection length is relatively limited. However, the fibers are typically quite long. To ensure comprehensive detection along the length of the fibers, in some embodiments, see the appendix... Figure 4 As shown, the transfer assembly 3 includes a sliding substrate 33 that can move along the length of the fiber filament, and a first clamping member 31 and a second clamping member 32 are both located on the sliding substrate 33. By moving the sliding substrate 33, the first clamping member 31 and the second clamping member 32 can drive the fiber filament to move, so that different parts of the fiber filament along its length can enter the mirror groove for detection.

[0037] Specifically, the machine tool 1 is equipped with a double-rail slide rail 11, and the sliding base plate 33 is equipped with a slider that can slide along the double-rail slide rail 11. When the slider moves along the double-rail slide rail 11, the sliding base plate 33 can drive the first clamping member 31 and the second clamping member 32 to move synchronously along the fiber length direction, so that the fiber clamped on the first clamping member 31 and the second clamping member 32 can move along the mirror groove, realizing the detection of different parts of the fiber.

[0038] In some embodiments, to ensure tension during fiber clamping, the second clamping member 32 can be configured to move along the sliding substrate 33 towards or away from the first clamping member 31. Specifically, the first clamping member 31 is fixed to the sliding substrate 33, and a groove 331 arranged along the fiber length direction is formed on the sliding substrate 33. A mounting base plate 34 for mounting the second clamping member 32 is slidably disposed in the groove. The movement of the second clamping member 32 on the sliding substrate 33 is achieved through the cooperation between the groove 331 and the mounting base plate 34.

[0039] In some embodiments, see Appendix Figure 5 As shown, both the first clamping member 31 and the second clamping member 32 include a clamping substrate 311, a fixed clamping arm 312, a movable clamping arm 313, and a driving member 314. The fixed clamping arm 312 is fixedly connected to the clamping substrate 311, and the movable clamping arm 313 can move along the clamping substrate 311 under the action of the driving member 314 (such as a cylinder), and together with the fixed clamping arm 312, clamp or release the fiber filament.

[0040] Specifically, both the fixed clamping arm 312 and the movable clamping arm 313 include cantilever arms arranged horizontally, with a clamping rod bent at the end of the cantilever arm away from the clamping substrate 311. When the movable clamping arm 313 moves under the action of the driving member 314, the clamping rod of the movable clamping arm 313 can move towards or away from the clamping rod of the fixed clamping arm 312. The cooperation of the cantilever arms and the clamping rods ensures the clamping function of the fiber filaments and facilitates the adjustment of the installation positions of the first clamping member 31 and the second clamping member 32 to make room for the vision inspection component.

[0041] Furthermore, an elastic pad 315 is provided on the side of the clamping rod facing the fiber filament to flexibly clamp the fiber filament, ensuring clamping force while avoiding damage to the surface of the fiber filament.

[0042] In some embodiments, see Appendix Figure 2 As shown, the visual inspection component 2 also includes a stand 23 and a linear module. The inspection camera 21 can move up and down along the stand 23 under the action of the linear module. The linear module facilitates the adjustment of the height of the inspection camera 21. Since the height adjustment and inspection principle of the inspection camera 21 are existing technologies, they will not be described in detail in this embodiment.

[0043] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
