Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber testing, in particular to a finished optical fiber testing device. Background Art

[0002] Fiber optic testing includes appearance and tensile testing, which are used to detect whether there are scratches, cracks, stains and other damage on the surface of the optical fiber, to ensure that the physical appearance of the optical fiber meets the standard requirements, thereby ensuring the quality and stability of optical fiber transmission. At the same time, the tensile test can detect the strength and durability of the optical fiber by applying tension, ensuring that the optical fiber will not break due to external pressure or tension during long-term use.

[0003] The prior art discloses patent application number "CN202322812045.6", which is a fiber optic tension testing device, including a base plate, with two groups of movable columns slidably connected to the top of the base plate, and clamping mechanisms are provided on the top of the two groups of movable columns. The two groups of clamping mechanisms are used to fix the two ends of the optical fiber respectively; and after turning on the motor, the rotating rod and the rotating gear can be driven to rotate. Under the reaction force, the two movable columns and the two ends of the optical fiber can be driven to separate and move simultaneously to achieve the purpose of stretching, which is convenient for tensile testing.

[0004] This test device can only facilitate the tensile test of the optical fiber. In actual use, the test device as mentioned above can usually only perform tensile testing on the optical fiber and cannot perform appearance testing. This requires time to be spent on testing again, which reduces the test efficiency and affects the test effect of the optical fiber finished product test device, making it inconvenient to use.

[0027] The inner side surfaces of the two retaining rings 10 are rotatably connected to the driven gear ring 11. Through the installation and use of the retaining rings 10 and the driven gear ring 11, the two retaining rings 10 can be used to limit the position of the driven gear ring 11, so that the driven gear ring 11 is in a rotatable state, thereby facilitating the adjustment of the appearance detection position and improving the test effect of the test device. One side of the driven gear ring 11 is fixedly connected to a first side plate 12, and the lower side of the first side plate 12 is fixedly provided with a visual inspection camera 13 for appearance testing. The model of the visual inspection camera 13 is MV-SC3050XM-16M-WBN. The visual inspection camera 13 is used to obtain a large amount of clear image data, which is matched with a pre-set standard to judge the quality of the optical fiber.

The outer surface of the first double-headed screw 5 is threadedly connected to two symmetrically arranged threaded vertical plates 6.

[0028] The upper sides of the two threaded vertical plates 6 are fixed with a U-shaped seat 7, and the inner sides of the two U-shaped seats 7 are rotatably connected to the second double-ended screw rods 17. The outer surfaces of the two second double-ended screw rods 17 are threadedly connected to two symmetrically arranged connecting plates 18. The inner sides of the four connecting plates 18 are connected to positioning arc plates 20. Through the setting of the positioning arc plates 20, two groups of positioning arc plates 20 can be more closely clamped to the optical fiber body 15 for firmly positioning the optical fiber to prevent the optical fiber from falling off. The inner sides of the four positioning arc plates 20 are all connected with rubber protrusions 21 in an array. The rubber protrusions 21 can increase the friction with the optical fiber, which is beneficial to improving the stability of the optical fiber and making the tensile test work more stable and safe. The optical fiber body 15 is installed inside the four positioning arc plates 20, and the left side of the first double-ended screw rod 5 passes through the U-shaped base frame 2 and extends to the left side of the U-shaped base frame 2.

The outer surfaces of the two round rods 24 are slidably connected to the inside of the connecting plate 18. Through the setting of the round rods 24, the two round rods 24 can be used to allow the two positioning arc plates 20 to move smoothly to clamp the optical fiber, which is easy to use.

[0030] The upper sides of the two U-shaped seats 7 are fixedly connected to a top frame 19, and the lower side of the top frame 19 is slidably connected to a limiting slide bar 25 for fixing the optical fiber body 15. A groove 27 is provided on the lower side of the limiting slide bar 25. The groove 27 allows the inside of the limiting slide bar 25 to fit into the outer surface of the optical fiber to improve the stability during the optical fiber tension test. A connecting spring 26 is connected between the top frame 19 and the limiting slide bar 25.

[0031] The upper side of the limiting slide rod 25 passes through the top frame 19 and extends to the upper side of the top frame 19.

The lower side of the positioning bolt 28 passes through the second side plate 23 and extends to the lower side of the second side plate 23.

[0032] One side of the driving gear shaft 14 passes through the U-shaped plate 9 and extends to one side of the U-shaped plate 9. One side of the driving gear shaft 14 is fixedly connected to the first servo motor 16 through the motor mounting plate. The driven gear ring 11 and the driving gear shaft 14 are meshed with each other. Two parallel limiting cross bars 30 are fixedly installed inside the U-shaped chassis 2. Both ends of the two threaded vertical plates 6 are connected to a slide 300. The outer surface of the limiting cross bar 30 is slidably connected to the inside of the slide 300. Through the setting of the limiting cross bar 30, the two limiting cross bars 30 can be used to guide the moving trajectory of the two threaded vertical plates 6, so that the two sets of positioning arc plates 20 can move smoothly to stretch the optical fiber, which is used to test the tensile strength quality of the optical fiber.

[0033] The working principle of the optical fiber product testing device provided by the utility model is as follows:

[0034] By inserting the optical fiber body 15 to be tested into the driven gear ring 11, and then using the motor of the electric slide 3 to drive the slider 4 to move back and forth on the electric slide 3 for adjustment, the slider 4 can drive the visual inspection camera 13 at the first side plate 12 to move, so that the visual inspection camera 13 can perform a comprehensive photo test on the upper end of the optical fiber, and then the first servo motor 16 drives the active gear shaft 14 to rotate, so that the active gear shaft 14 can drive the meshing driven gear ring 11 to rotate, so that the visual inspection camera 13 rotates to the bottom of the optical fiber body 15, so that the visual inspection camera 13 can take photos and detect the lower end of the optical fiber while moving, so as to comprehensively test the appearance of the optical fiber and improve the processing quality of the optical fiber;

[0035] By placing the optical fiber body 15 to be tested into the interior of the two sets of positioning arc plates 20, and then rotating the two fixed hand wheels 22 respectively, the second double-headed screw rod 17 can be driven to rotate and the two connecting plates 18 can move toward each other, ensuring that the two sets of positioning arc plates 20 and the rubber protrusions 21 can firmly clamp and fix the optical fiber together, and then the positioning bolts 28 are rotated in sequence, so that the positioning bolts 28 squeeze the limiting slide rod 25 equipped with the connecting spring 26 and move downward, so that the limiting slide rod 25 can be positioned above the optical fiber for stable and reliable testing. Then the output shaft of the second servo motor 29 drives the first double-headed screw rod 5 to rotate. At this time, the two threaded vertical plates 6 on the first double-headed screw rod 5 can move relative to each other, so that the two sets of positioning arc plates 20 simultaneously stretch the two ends of the optical fiber, which is convenient for tensile testing. At the same time, the tensile strength quality of the optical fiber can be judged according to the spacing length of the two threaded vertical plates 6. If the optical fiber is not broken within the specified spacing, it means that the optical fiber meets the quality requirements.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
