Description

Technical Field

[0001] This invention relates to the field of fiber optic connector technology, and more particularly to an offset measuring device. Background Technology

[0002] For fiber optic rotary connectors, the precise assembly of the gold wires, the main metal components of the connector, plays a crucial role in ensuring that the rotating optical fiber inside the connector is always in the center of the rotation axis and transmits signals stably and continuously. The gold wires on the connector are tightly wound on the connector, and during the winding process, the gold wires are prone to shift, causing the rotating optical fiber to deviate from the center of the rotation axis, thereby reducing the quality of the connector.

[0003] Currently, there are no specialized tools or devices in existing technology for measuring the offset of gold wires on fiber optic rotary connectors. Generally, the following two methods are used for detection: 1. Using a device with image recognition technology (such as a flash meter) to photograph the assembled gold wires and then identify the offset. This method involves high equipment costs, is difficult to focus when photographing curved objects, has poor accuracy, and is difficult to assemble. 2. Assembly personnel identify the offset by visual inspection, but this method is difficult to distinguish whether the gold wires have shifted, has a large error, and is not easy to identify and quantify the offset. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide an offset measuring device that solves the problems of difficulty, complexity of operation, and poor accuracy in measuring the offset of gold wires on optical fiber rotary connectors in the prior art.

[0005] The objective of this invention is mainly achieved through the following technical solutions: The present invention provides an offset measuring device, including a fixed column, a movable block, and a detection device; the movable block is sleeved on the fixed column and can move vertically along the fixed column, and the detection device is connected to the movable block.

[0006] Furthermore, it also includes a fixing plate, which consists of a plate body and lifting outriggers; fixing columns are installed on the plate body; and lifting outriggers are installed at the four bottom corners of the plate body.

[0008] Furthermore, the movable block includes a first movable block, a second movable block, and a first connecting rod; the first movable block and the second movable block are respectively located at both ends of the first connecting rod.

[0009] Furthermore, the first movable block includes a block body with a first cavity, and the second movable block has a second cavity. The movable block is fitted onto the fixed column through the first cavity and the second cavity.

[0014] Furthermore, the horizontal bar is designed with an inner and outer tube structure, and the inner and outer tubes can move relative to each other via a slide rail.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: (1) The offset measuring device of the present invention includes a first moving block, a second moving block and a first connecting rod.

[0016] (2) In the offset measuring device of the present invention, one end of the horizontal rod on the detection device is connected to the moving block and the other end is connected to the detection piece, so that the detection piece can move in both horizontal and vertical directions through the horizontal rod and the moving block, which is highly flexible.

[0017] (3) In the offset measuring device of the present invention, the magnifying glass in the detection device is provided with a bracket, and the bracket is slidably connected to the first track on the detection plate, so that the magnifying glass can move horizontally along the detection plate, which facilitates flexible adjustment of the position of the magnifying glass.

Detailed Implementation

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0023] Example 1 The offset measuring device provided in this embodiment, such as Figure 1 As shown, it includes a fixed plate 1, a fixed column 2, a movable block 3, and a detection device 4; the fixed column 2 is vertically fixed on the fixed plate 1, the movable block 3 is sleeved on the fixed column 2 and can move vertically along the fixed column 2; the detection device 4 is connected to the movable block 3.

[0024] The fixed plate 1 is a square plate, including a plate body 11, lifting legs 12, and a level 13; the four corners of the bottom surface of the plate body 11 are provided with lifting legs 12, which can adjust the height of the four corners of the fixed plate 1 to keep the fixed plate 1 level, thus adapting to different planes; further, see Figure 2 The lifting outrigger 12 includes a first base 121 and a threaded post 122. The threaded post 122 is mounted on the first base 121. Threaded holes are provided at the four corners of the bottom surface of the plate 11. The threaded post 122 is connected to the threaded holes. By rotating the first base 121, the threaded post 122 is moved within the threaded holes, thereby changing the height of the four corners of the plate 11. This makes it easier to keep the plate 11 horizontal and adapt to different planes.

[0025] Furthermore, a level 13 is mounted on the plate 11, with its central axis parallel to the horizontal centerline of the plate 11. The level 13 is a bubble level, containing a colored liquid with bubbles inside its tube. The tube has two graduation lines. When the level 13 is horizontal, the bubble is located in the middle of the two graduation lines. When the level 13 is not horizontal, the bubble deviates from the middle position of the two graduation lines. The plate 11 is horizontal by observing the relative position between the bubble and the graduation lines. When the level is horizontal, the plate 11 is also horizontal; when the level is not horizontal, the plate 11 is not horizontal.

[0026] The fixed column 2 is a cylinder, including a column body 21 and a first slide rail 22. The first slide rail 22 is located on the side of the column body 21. The first slide rail 22 is preferably a block. The center line of the first slide rail 22 is parallel to the column body 21 and matches the cavity on the moving block 3. This not only allows the moving block 3 to be fitted onto the fixed column 2 and move vertically, but also allows the moving block 3 to be radially limited on the column body 21.

[0027] See Figure 3 The movable block 3 includes a first movable block 31, a second movable block 32 and a first connecting rod 33. The first movable block 31 and the second movable block 32 are located at both ends of the connecting rod 33. The first movable block 31 includes a block body 311 and an adjusting screw 312. The adjusting screw 312 is threadedly connected to the block body 311.

[0028] The block 311 has a first cavity 3111, and the second moving block 32 has a second cavity 321. The moving block 3 is fitted onto the fixed post 2 through the first cavity 3111 and the second cavity 321. The first cavity 3111 and the second cavity 321 are in contact with the outer surface of the fixed post 2 to ensure the stability of the moving block on the fixed post 2.

[0029] The side wall of the block 311 is provided with a threaded hole, which communicates with the first cavity 3111. The adjusting screw 312 is connected to the threaded hole. Tightening the adjusting screw 312 can make it pass through the threaded hole and press against the fixed column 2 located in the movable block 3, thus fixing the movable block 3 on the fixed column 2. Tightening the adjusting screw 312 in the opposite direction can separate it from the fixed column 2, allowing the movable block 3 to move vertically on the fixed column 2.

[0030] Furthermore, the end of the adjusting screw 312 that contacts the fixed post 2 is provided with an anti-slip layer, preferably a rubber layer, which can improve the stability of the moving block 3 on the fixed post 2.

[0031] Further, see Figure 1The second moving block 32 is equipped with a displacement sensor 322, which is used to detect the moving distance of the second moving block 32 in the vertical position. When the second moving block 32 moves along the fixed column 2 to the fixed plate 1, the reading displayed by the displacement sensor 322 is zero. As the second moving block 32 moves upward along the fixed column 2, the reading displayed by the displacement sensor 322 increases. The size of the reading is equal to the distance between the second moving block 32 and the plate 11, thereby realizing the detection of the vertical moving distance of the second moving block 32.

[0032] It should be noted that the first moving block 31 and the second moving block 32 are connected by the first connecting rod 33, so that the first moving block 31 and the second moving block 32 move and are fixed synchronously on the fixed column 2. The first moving block 31 is fixed on the fixed column 2 by adjusting screw 312, and the second moving block 32 detects the displacement of the moving block 3 by displacement sensor 322, so that the moving block 3 can realize the dual functions of fixing and displacement measurement.

[0033] The detection device 4 includes a horizontal rod 41, a detection piece 42, an intermediate rod 43, and a magnifying glass 44. The center line of the horizontal rod 41 is perpendicular to the center line of the fixed column 2. One end of the horizontal rod 41 is fixedly connected to the second moving block 32, and the other end is connected to the intermediate rod 43. The intermediate rod 43 is connected to the detection piece 42. The magnifying glass 44 is mounted on the detection piece 42. The detection piece 42 can move horizontally via the horizontal rod 41 and can also move vertically via the moving block 3.

[0034] Furthermore, one end of the intermediate rod 43 is provided with a groove, into which the detection piece 42 can be inserted for pasting and fixing.

[0035] Specifically, the horizontal bar 41 is designed as an inner and outer sleeve structure, and the inner sleeve and the outer sleeve move relative to each other through a slide rail.

[0036] Furthermore, an anti-slip coating is applied between the inner and outer sleeves to increase the relative friction between them, allowing them to be relatively fixed in the absence of external force.

[0037] The intermediate rod 43 is set as a bent tube with a bending angle of 90°, so that the detection piece 42 is located above the horizontal rod 41, avoiding friction or obstruction between the detection piece 42 and the horizontal rod 41 when the detection piece 42 moves with the horizontal rod 41.

[0038] See Figure 4 The detection plate 42 includes a plate body 421, a first track 422 and a first handle 423; the first track 422 is located at the horizontal end of the plate body 421, the first handle 423 is located at the vertical end of the plate body 421, and the magnifying glass 44 is located on the first track 422 and can move horizontally along the first track 422.

[0039] See Figure 5Specifically, the first track 422 includes a second slide rail 4221 and a channel 4222. The second slide rail 4221 is configured as a U-shaped groove, and the channel 4222 is located below the second slide rail 4221. The magnifying glass 44 can move horizontally on the first track 422.

[0040] See Figure 6 , Figure 7 The magnifying glass 44 includes a lens 441, a support 442, and a connecting block 443. The support 442 is located between the lens 441 and the connecting block 443. The connecting block 443 is slidably connected to the first track 422. The connecting block 443 includes a frame 4431 with a cavity, a locking block 4432, and a second handle 4433. The locking block 4432 is located inside the top plate of the frame 4431, and the second handle 4433 is located outside the top plate of the frame 4431. The connecting block 443 is fitted onto the second slide rail 4221 through the cavity of the frame 4431. At the same time, the locking block 4432 is inserted into the groove of the second slide rail 4221, so that the connecting block 443 fits against the second slide rail 4221, allowing the connecting block 443 to move smoothly along the second slide rail 4221. The channel 4222 is for the connecting block 443 to fit onto the second slide rail 4221 and move along the second slide rail 4221.

[0041] Furthermore, the connecting block 443 is fitted with the first track 422 to ensure the stability of the connecting block 443 on the first track 422.

[0042] Further, see Figure 8 The bracket 442 includes a first support rod 4421, a second support rod 4422 and a third support rod 4423 connected vertically in sequence, with the first support rod 4421 and the third support rod 4423 located on both sides of the second support rod 4422. The first support rod 4421 is connected to the connecting block 443 and the third support rod 4423 is connected to the lens 441.

[0043] Further, see Figure 4 The test piece 42 has a rectangular test slit 4211 on its body 421, through which the gold wires wound on the optical fiber rotary connector 6 can be observed.

[0044] Furthermore, the lens 441 of the magnifying glass 44 is located between the inspection slit 4211 and the fiber optic rotary connector 6 under inspection, so that the gold wire of the fiber optic rotary connector 6 under inspection is magnified by the lens 441, making it easier for the operator to observe it from the inspection slit 4211.

[0045] Furthermore, the fiber optic rotary connector 6 is a circular cylinder with a cavity, and the fiber optic rotary connector 6 is fitted onto the fixing frame 5 through the cavity.

[0046] Furthermore, the fixing frame 5 includes a second connecting rod 51, a vertical rod 52, and a second base 53. One end of the second connecting rod 51 is perpendicularly connected to the plate 11, and the other end is perpendicularly connected to the vertical rod 52. The second base 53 is fixedly sleeved on the lower end of the vertical rod 52 and located at the upper end of the second connecting rod 51. When the fiber optic rotating connector 6 is being tested, it is sleeved on the vertical rod 52 through the cavity, and the second base 53 provides axial positioning for the fiber optic rotating connector 6. The center line of the second base 53 overlaps with the center line of the vertical rod 52, and the inner surface of the cavity of the fiber optic rotating connector 6 is in contact with the vertical rod 52, ensuring that the fiber optic rotating connector 6 is in the vertical direction relative to the testing device 4, thus ensuring measurement accuracy.

[0047] Example 2 This embodiment is another design based on Embodiment 1.

[0048] See Figure 9 The magnifying glass 44 is mounted on the detection plate 42 and can cover the detection slit 4211 on the detection plate 42, so that when the operator observes through the detection slit 4211, he can directly magnify through the magnifying glass 44, which is convenient for observation.

[0049] See Figure 10 The horizontal bar 41 is a straight bar, and the plate 1 is provided with a second track 14, including a track body 141, a connecting plate 142, a lead screw 143 and a knob 144. The track body 141 is convex in shape, which allows the column 21 to be locked onto the track body 141 through the groove at the lower end and to move horizontally along the track body 141. The groove at the lower end of the column 21 fits into the track body 141 to ensure stability. The connecting plate 142 is located at one end of the track body 141 and has a threaded hole. One end of the lead screw 143 can pass through the threaded hole, so that the lead screw 143 can move horizontally through the threaded hole and be fixed at different horizontal positions. The other end of the lead screw 143 is rotatably connected to the column 21, so that the lead screw 143 drives the column 21 to move horizontally and be fixed at different horizontal positions while moving horizontally.

[0050] Furthermore, the lead screw 143 passes through the threaded hole of the connecting plate 142 and is connected to the knob 144. Turning the knob 144 causes the lead screw 143 to move horizontally.

[0051] It should be noted that when the operator performs the test, they hold the first handle 423 to move the test piece 42, and simultaneously position the offset gold wire wound on the optical fiber rotary connector 6 through the test seam 4211, aligning the right-angle intersection of the upper end of the test seam 4211 with one end of the offset gold wire, as shown below. Figure 11As shown, the reading on the displacement sensor 322 is recorded. Then, the detection plate 42 is moved so that the other end of the offset gold wire overlaps with the upper edge of the detection slot 4211. The reading on the displacement sensor 322 is recorded at this time. The absolute value of the difference between the readings of the two displacement sensors 322 is the vertical offset of the gold wire being tested. The magnitude of the offset can be used to determine the offset of the gold wire being tested on the optical fiber rotary connector. The smaller the offset, the better the gold wire is wound, and the better the quality of the optical fiber rotary connector.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
