Description

Technical Field

[0001] This utility model relates to the field of optical fiber production positioning marking technology, and in particular to an optical fiber positioning marking device. Background Technology

[0002] In the process of optical fiber production, in order to ensure the quality of optical fiber products, improve production efficiency, and facilitate subsequent use and maintenance, optical fiber positioning and marking equipment is usually used to accurately position and fix the optical fiber using optical or mechanical methods, ensuring that the marking equipment can accurately mark the designated position on the optical fiber.

[0003] In existing laser marking machines, the conveyor belt transports the produced optical fibers to the laser marking area for positioning and marking. Because the optical fibers themselves are soft and thin, the vibration force generated by the conveyor belt during operation is easily transmitted to the optical fibers, which can easily cause the optical fibers to bend under external force, thus affecting the positioning and marking effect of the optical fibers. Utility Model Content

[0004] Therefore, it is necessary to provide an optical fiber positioning and marking device to address the problem that the vibration force generated by the conveyor belt during operation can be easily transmitted to the optical fiber, which in turn can easily cause the optical fiber to bend under the action of external force.

[0005] The system includes: a worktable, on the top of which is mounted a laser marking mechanism and a conveyor; and a positioning mechanism, comprising a bracket fixedly connected to the top of the conveyor, the surface of which is slidably connected to a movable frame, and several rubber wheels rotatably connected to the inner wall of the movable frame, each rubber wheel having two circular grooves on its surface. Through the interaction of the bracket, movable frame, rubber wheels, and circular grooves, multi-point flexible rolling contact limiting of the optical fiber on the conveyor is achieved, thereby preventing the optical fiber from bending during its movement on the conveyor and ensuring that the optical fiber enters the laser marking mechanism straight for laser marking, thus guaranteeing the effective positioning and marking of the optical fiber.

[0006] In one embodiment, a dustproof cylinder is fixedly connected to the surface of the bracket, and the surface of the movable frame is slidably connected to the inner wall of the dustproof cylinder.

[0007] In one embodiment, a lead screw is rotatably connected to the inner wall of the dustproof cylinder, and the inner wall of the movable frame is threaded to the surface of the lead screw. The rotating lead screw adaptively adjusts the longitudinal position of the movable frame and the rubber wheel, ensuring stable rolling contact between the circular groove and optical fibers of different diameters. This ensures the optical fiber enters the laser marking mechanism in a straight line for laser marking. The dustproof cylinder serves to enclose the surface of the lead screw, preventing impurities from adhering to its surface and reducing wear between the lead screw and the movable frame.

[0008] In one embodiment, the inner wall of the movable frame is slidably connected to two guide rods, and the inner wall of the guide rods is slidably connected to rubber balls.

[0009] In one embodiment, a first spring is fixedly connected to the opposite end of the guide rod and the movable frame. Through the interaction of the first spring, the guide rod, and the rubber ball, flexible rolling contact of the optical fiber is achieved, and the longitudinal position of the rubber wheel is limited. This prevents excessive rolling pressure from the circular groove on the optical fiber surface, ensuring the positioning effect of the moving optical fiber on the conveyor, and thus ensuring the positioning marking effect of the optical fiber. In one embodiment, a slider is slidably connected to the upper end of the inner wall of the lead screw, and a toothed block is fixedly connected to one side of the slider.

[0010] In one embodiment, a ring of triangular blocks is fixedly connected to the upper surface of the dustproof cylinder.

[0011] In one embodiment, a second spring is fixedly connected to one end of the slider, and the other end of the second spring is fixedly connected to the upper end of the inner wall of the lead screw. Through the interaction of the second spring, slider, toothed block, and triangular block, the resistance to the rotation of the lead screw is increased, thereby ensuring that the circular groove steadily rolls against the surface of the optical fiber, ensuring the positioning effect of the moving optical fiber on the conveyor, and thus ensuring the positioning marking effect of the optical fiber.

[0012] Beneficial effects

[0013] 1. By cooperating with the bracket, movable frame, rubber wheels and circular groove, multi-point flexible rolling contact limiting of the optical fiber on the conveyor is realized, thereby avoiding the bending of the optical fiber during movement on the conveyor, ensuring that the optical fiber enters the laser marking mechanism in a straight line for laser marking, and thus ensuring the positioning and marking effect of the optical fiber. 2. By cooperating with the first spring, guide rod and rubber ball, the optical fiber is flexibly rolled and the longitudinal position of the rubber wheel is limited, avoiding excessive rolling of the circular groove on the surface of the optical fiber, ensuring the positioning effect of the moving optical fiber on the conveyor, and thus ensuring the positioning marking effect of the optical fiber.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes the fiber optic positioning and marking device.

[0019] In one embodiment, a fiber optic positioning and marking device includes: a workbench 100, on the top of which a laser marking mechanism 200 and a conveyor 300 are mounted; it also includes a positioning mechanism 400, which includes a bracket 401 fixedly connected to the top of the conveyor 300, the surface of the bracket 401 being slidably connected to a movable frame 402, and a plurality of rubber wheels 403 being rotatably connected to the inner wall of the movable frame 402, the surface of the rubber wheels 403 having two circular grooves 404.

[0020] It should be noted that the conveyor 300 model can be an SPC-L series. The laser marking machine consists of a worktable 100, a laser marking mechanism 200, a conveyor 300, and a display screen, etc. The laser marking machine model can be a Han's Laser MOPA series.

[0021] In this embodiment, when the produced optical fiber needs to be positioned and marked, the produced optical fiber is guided to the conveyor belt on the conveyor 300 between the opposite surface of the circular groove 404, and the movable frame 402 is pushed down in the bracket 401, so that multiple rubber wheels 403 move down at the same time, thereby making the circular groove 404 flexibly roll against the surface of the optical fiber.

[0022] At this time, the conveyor 300 is manually started, and the limited optical fiber is straightly transported to the marking area of ​​the laser marking mechanism 200 via the conveyor belt. The vision recognition system composed of an industrial camera and image processing software on the laser marking mechanism 200 monitors and positions the optical fiber in real time. The camera captures an image of the optical fiber, the software analyzes the image to determine the position and orientation of the optical fiber, and feeds the information back to the control system of the laser marking machine to achieve precise positioning and marking.

[0023] After fiber positioning is completed, the laser marking machine's marking program is started. The marking software transmits the pre-set marking content and parameters to the laser marking machine's control system. The laser beam is focused onto the fiber surface by the overfocusing lens on the laser marking mechanism 200, concentrating the laser energy in a very small area, thereby creating a permanent mark on the fiber surface.

[0024] During laser marking, the laser marking machine's control system controls the scanning and movement of the laser beam according to preset parameters and paths to complete the marking. Simultaneously, it monitors various parameters in real time, such as laser power and marking speed, to ensure the stability of the marking quality.

[0025] like Figure 4-5 As shown, a dustproof cylinder 405 is fixedly connected to the surface of the bracket 401, and the surface of the movable frame 402 is slidably connected to the inner wall of the dustproof cylinder 405. A lead screw 406 is rotatably connected to the inner wall of the dustproof cylinder 405, and the inner wall of the movable frame 402 is threadedly connected to the surface of the lead screw 406. Two guide rods 407 are slidably connected to the inner wall of the movable frame 402, and rubber balls 408 are rolledly connected to the inner wall of the guide rods 407. A first spring 409 is fixedly connected to the opposite end of the guide rods 407 and the movable frame 402.

[0026] In this embodiment, rotating the lead screw 406 causes the movable frame 402 to move downward within the dustproof cylinder 405. The downward-moving movable frame 402 drives the rubber wheel 403, guide rod 407, rubber ball 408, and first spring 409 to move downward simultaneously. The elastic force of the first spring 409 pushes the guide rod 407 downward, causing the rubber ball 408 to first roll and contact the surface of the optical fiber. At this time, the movable frame 402 drives the rubber wheel 403 and the first spring 409 to continue to move downward, causing the guide rod 407 to stretch the first spring 409. The bottom of the movable frame 402 abuts against the end of the guide rod 407, stopping the rotation of the lead screw 406, and causing the circular groove 404 to flexibly roll and contact the surface of the optical fiber.

[0027] like Figure 4 As shown, a slider 411 is slidably connected to the upper end of the inner wall of the lead screw 406, a toothed block 412 is fixedly connected to one side of the slider 411, a ring of triangular blocks 410 is fixedly connected to the upper end of the surface of the dustproof cylinder 405, a second spring 413 is fixedly connected to the end of the slider 411, and the other end of the second spring 413 is fixedly connected to the upper end of the inner wall of the lead screw 406.

[0028] In this embodiment, after the lead screw 406 rotates to a suitable position, the restriction on the slider 411 is loosened. The elastic force of the second spring 413 pushes the slider 411 to move laterally within the lead screw 406, so that the surface of the tooth block 412 abuts against the surface of the corresponding triangular block 410, thereby increasing the rotational resistance of the lead screw 406.

[0029] Working principle: The produced optical fiber is guided to the conveyor belt on the conveyor 300 between the opposite surfaces of the conveyor belt and the circular groove 404. This pulls the slider 411 to move laterally within the lead screw 406, causing the toothed block 412 to move away from the surface of the triangular block 410. This pushes the slider 411 to move in a ring, causing the lead screw 406 to rotate within the dustproof cylinder 405. This causes the movable frame 402 to move downward within the dustproof cylinder 405, simultaneously moving the rubber wheel 403, guide rod 407, rubber ball bearings 408, and the first spring 409 downward. The elastic force of the first spring 409 pushes the guide rod 407 downward. The movement causes the rubber ball 408 to first roll into contact with the surface of the optical fiber. At this time, the movable frame 402 drives the rubber wheel 403 and the first spring 409 to continue to move downward, causing the guide rod 407 to stretch the first spring 409. The bottom of the movable frame 402 abuts against the end of the guide rod 407, stopping the rotation of the screw 406. This causes the circular groove 404 to flexibly roll into contact with the surface of the optical fiber, loosening the restriction on the slider 411. The elastic force of the second spring 413 pushes the slider 411 to move laterally within the screw 406, causing the surface of the toothed block 412 to abut against the surface of the corresponding triangular block 410.

[0030] It should be noted that the workbench 100, laser marking mechanism 200, conveyor 300, first spring 409 and second spring 413 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the laser marking mechanism 200 and conveyor 300 can be powered by built-in power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
