Description

Technical Field

[0001] This application belongs to the field of optical fiber processing technology, specifically relating to an optical fiber end face inspection device. Background Technology

[0002] Optical fiber is a long, thin, transparent fiber made of high-purity glass or plastic. It enables high-speed information transmission using the principle of total internal reflection of light and is mainly used in communications, sensing, measurement, and medical fields. Optical fibers typically consist of a core and a cladding. The cladding has a lower refractive index than the core, allowing light signals to propagate within the core via total internal reflection.

[0003] In long-distance signal transmission, connectors are typically used to connect the end faces of two optical fibers. Different types of optical fibers usually require different connectors. After the connector is connected to the optical fiber, the end face of the fiber needs to be inspected. Multiple inspection devices are typically required for different types of optical fibers and connectors, resulting in high costs. Summary of the Invention

[0004] The technical problem this application aims to solve is that for different types of optical fibers and connectors, multiple testing devices are required to test the end face of the optical fiber separately, which is costly. To solve this technical problem, this application provides an optical fiber end face testing device that can test the end face of different types of optical fibers at a lower cost.

[0005] The technical solution proposed in this application is as follows: An optical fiber end-face inspection device, comprising: Base; A displacement stage is disposed on the base; A rotary table is rotatably connected to the displacement table and can move relative to the base under the action of the displacement table. The rotary table is provided with a first mounting position and a second mounting position, and the first mounting position can be used to install optical fibers. Multiple mounting components, each of which is detachably connected to a second mounting position on the rotary table, and the multiple mounting components are capable of mounting different connectors; The testing mechanism is located on the base; During the rotation of the rotary table, the first mounting position and the second mounting position can pass through the detection position in sequence, so that the detection mechanism can detect the optical fiber at the detection position.

[0006] The aforementioned fiber optic end-face inspection device involves mounting a connector with an optical fiber onto a mounting component, then placing the mounting component in the second mounting position of a rotary table. Rotating the rotary table until the second mounting position reaches the inspection position allows the inspection mechanism to check the fiber optic end-face. Since the mounting component and the second mounting position are detachably connected, and multiple mounting components can accommodate different connectors, it is possible to inspect different types of optical fibers connected with connectors without requiring multiple inspection devices, thus reducing equipment costs. Furthermore, a bare optical fiber can be mounted in the first mounting position. Rotating the rotary table to bring the first mounting position to the inspection position allows the inspection mechanism to check the end-face of the bare optical fiber. This device is suitable for inspecting fiber optic end-faces under various conditions, improving its versatility.

[0007] Furthermore, it also includes a positioning component, which is movably connected to the displacement table, and the rotary table has multiple positioning slots; The positioning member can abut against the rotating table during its movement, and can be inserted into the positioning slot during the rotation of the rotating table. When the positioning element is inserted into any of the positioning slots, the rotary table can be fixed relative to the displacement table, and there is a mounting position at the detection position.

[0008] Furthermore, it also includes an elastic element disposed between the displacement stage and the positioning element, which provides a force to press the positioning element against the rotary table.

[0009] Furthermore, it also includes a connecting arm, one end of which is connected to the displacement stage. The rotary table is rotatably connected to the end of the connecting arm away from the displacement stage via a connecting shaft. The positioning member is movably connected to the connecting arm and can abut against the side wall of the connecting shaft during its movement. A plurality of positioning grooves are formed on the side wall of the connecting shaft along the circumference of the connecting shaft.

[0010] Furthermore, it also includes an angle adjustment mechanism, the displacement stage is connected to the angle adjustment mechanism, and the angle adjustment mechanism is connected to the connecting arm to drive the connecting arm to rotate.

[0011] Furthermore, it also includes multiple clamps, each of which is detachably connected to a first mounting position on the rotary table, and the clamps are capable of positioning optical fibers.

[0012] Furthermore, it also includes a cleaning mechanism disposed on the base, with the output end of the cleaning mechanism facing the mounting position rotated to the detection position, in order to clean the end face of the optical fiber.

[0013] Furthermore, the output end of the cleaning mechanism includes a liquid spray nozzle and an air spray nozzle. The liquid spray nozzle can spray cleaning liquid toward the end face of the optical fiber, and the air spray nozzle can spray dry gas toward the end face of the optical fiber.

[0014] Furthermore, the displacement stage includes a first translation drive, a second translation drive, and a third translation drive. The first translation drive is disposed on the base and connected to the second translation drive. The second translation drive is connected to the third translation drive, and the third translation drive is connected to the rotary table.

[0015] Furthermore, the detection mechanism includes a microscope and multiple lenses adapted to the microscope, the multiple lenses having different magnifications.

[0016] In summary, the fiber optic end-face inspection device provided in this application has at least the following advantages: 1. By setting up multiple mounting parts that can install different connectors, and each mounting part is detachably connected to the second mounting position of the rotary table, the fiber end face inspection device can inspect different types of optical fibers with connectors, eliminating the need to set up multiple inspection devices and reducing equipment costs. 2. The rotating table is also equipped with multiple first mounting positions, each of which can be equipped with a fixture. The multiple fixtures can position bare optical fibers of different sizes, further improving the versatility of the optical fiber end face inspection device. 3. When the rotating table is rotated to the detection position from any installation position, the positioning component is inserted into the corresponding positioning slot to fix the rotating table relative to the displacement stage, thereby ensuring the stability of the rotating table during the detection process, improving the clarity of the obtained image, and thus improving the accuracy of the detection. 4. By setting up a cleaning mechanism to clean the end face of the optical fiber, it is possible to avoid impurities on the end face of the optical fiber from affecting the test results, thereby improving the accuracy of the test.

[0026] To achieve low-cost inspection of the end faces of different types of optical fibers connected with connectors, this application provides an optical fiber end face inspection device, which can inspect the end faces of multiple optical fibers of different types, all connected with corresponding connectors, thereby reducing equipment costs.

[0027] like Figures 1 to 3 As shown, in one embodiment, the fiber optic end face inspection device includes a base 110, a displacement stage 120, a rotation stage 130, an inspection mechanism 140, and a plurality of mounting components 151.

[0028] The displacement stage 120 and the detection mechanism 140 are both mounted on the base 110. The rotary table 130 is rotatably connected to the displacement stage 120 and can move relative to the base 110 under the action of the displacement stage 120. Please also refer to... Figure 4 The rotary table 130 is provided with a first mounting position 131 and a second mounting position 132. The first mounting position 131 can be used to install optical fibers, and the mounting component 151 is detachably connected to the second mounting position 132 of the rotary table 130. The mounting component 151 can be used to install connectors, and multiple mounting components 151 can be used to install different connectors.

[0029] During the rotation of the rotary table 130, the first mounting position 131 and the second mounting position 132 can pass through the detection position in sequence, so that the detection mechanism 140 can detect the optical fiber at the detection position. That is, when one of the first mounting position 131 and the second mounting position 132 rotates to the detection position, the detection mechanism 140 can detect the end face of the optical fiber at the detection position.

[0030] It should be explained that each mounting piece 151 can be connected to the second mounting position 132, and multiple mounting pieces 151 can accommodate different connectors. This allows different connectors to be rotated to the detection position as needed, enabling the detection mechanism 140 to detect different types of optical fibers. Furthermore, the connection between the mounting piece 151 and the second mounting position 132 can be achieved through bolt connections or quick-connect connections, providing a convenient, fast, and stable connection.

[0031] Using the aforementioned fiber optic end-face inspection device, a connector with an optical fiber is mounted on the mounting component 151. The mounting component 151 is then mounted on the second mounting position 132 of the rotary table 130. The rotary table 130 is rotated until the second mounting position 132 is in the inspection position, allowing the inspection mechanism 140 to inspect the end face of the optical fiber. Since the mounting component 151 and the second mounting position 132 are detachably connected, and multiple mounting components 151 can accommodate different connectors, different types of optical fibers connected with connectors can be inspected without the need for multiple inspection devices, thus reducing equipment costs. Alternatively, a bare optical fiber can be mounted on the first mounting position 131. Rotating the rotary table 130 rotates the first mounting position 131 to the inspection position, allowing the inspection mechanism 140 to inspect the end face of the bare optical fiber. This device is suitable for inspecting fiber optic end faces under different conditions, improving its versatility.

[0032] Specifically Figure 1 In the illustrated embodiment, the rotary table 130 is provided with a plurality of first mounting positions 131, each of which can mount optical fibers of different sizes. It is understood that for different types of optical fibers connected with connectors, connection to the second mounting position 132 can be achieved by changing different mounting parts 151; therefore, the number of second mounting positions 132 can be set to one. Of course, multiple second mounting positions 132 can also be provided, and this is not limited here.

[0033] In practical applications, the fiber optic end-face inspection device also includes multiple clamps 152, each of which is detachably connected to the first mounting position 131 of the rotary table 130. Each clamp 152 can position the optical fiber, thereby mounting it in the first mounting position 131. Furthermore, multiple clamps 152 can hold optical fibers of different sizes, further improving versatility. It should be further explained that different types of optical fibers typically include fibers of different sizes and fibers with different end-face angles. Different sizes and end-face angles require different connectors. However, clamps 152 can hold optical fibers of the same size but with different end-face angles. Therefore, for the same batch of optical fibers, the number of connectors is usually greater than the number of clamps 152. If multiple second mounting positions 132 are provided for different connectors, more second mounting positions 132 are needed. Therefore, it is preferable that the number of first mounting positions 131 is greater than the number of second mounting positions 132, thereby reducing the frequency of changing clamps 152.

[0034] Furthermore, such as Figure 5 As shown, the first mounting position 131 of the rotary table 130 has a mounting hole 133, and the clamp 152 is installed in the first mounting hole 133 so that after the optical fiber is clamped and positioned in the clamp 152, the end of the optical fiber can pass through the clamp 152 and the rotary table 130 for detection by the detection mechanism 140.

[0035] In one embodiment, the base 110 is provided with multiple rubber feet on its bottom to improve the stability of the base 110, ensuring overall stability during the detection process and facilitating the acquisition of clear images. Furthermore, handles 111 are connected to opposite sides of the base 110 to facilitate the handling and transport of the device.

[0036] In one embodiment, the inspection mechanism 140 includes a microscope 141 and multiple lenses 142 adapted to the microscope 141, each lens 142 having a different magnification. Thus, different lenses 142 can be switched as needed to inspect the fiber optic end face at different magnifications. It should be noted that switching between different lenses 142 on the microscope 141 is a routine operation, and the specific magnification can be determined according to actual needs, which will not be elaborated upon here.

[0037] It should be noted that in this embodiment, the brightness of the light source inside the lens 142 can be adjusted. For example, an adjustment button can be added to the outside of the detection mechanism 140 to facilitate brightness adjustment and obtain images for different needs.

[0038] In one embodiment, the displacement stage 120 includes a first translation drive, a second translation drive, and a third translation drive. The first translation drive is disposed on the base 110 and connected to the second translation drive, the second translation drive is connected to the third translation drive, and the third translation drive is connected to the rotary stage 130. Thus, the displacement stage 120 can drive the rotary stage 130 to move in three dimensions, thereby adjusting the position of the rotary stage 130. This allows the position of the rotary stage 130 to be adjusted according to the focal length of the lens 142, ensuring that the end face of the optical fiber on the rotary stage 130 is clearly imaged within the microscope 141. Optionally, the first, second, and third translation drives are all linear modules or sliding stages.

[0039] In one embodiment, the fiber optic end face detection device further includes a connecting arm 161. One end of the connecting arm 161 is connected to the displacement stage 120, and the rotary stage 130 is rotatably connected to the end of the connecting arm 161 away from the displacement stage 120.

[0040] In a preferred embodiment, the fiber optic end-face inspection device further includes an angle adjustment mechanism (not shown). The displacement stage 120 is connected to the angle adjustment mechanism, i.e., the third translation drive is connected to the angle adjustment mechanism. The angle adjustment mechanism is connected to the connecting arm 161 to drive the connecting arm 161 to rotate, thereby adjusting the angle of the fiber on the rotary stage 130. Thus, when inspecting fiber optic end faces at different angles, it can be ensured that the entire fiber optic end face is clearly imaged within the microscope 141.

[0041] It should be explained that, in order to control the reflection behavior of light at the optical fiber junction and meet the return loss and signal quality requirements in different scenarios, the end face of the optical fiber is designed with different angles, such as the commonly used 0° and 8°. If the angle of the optical fiber is not adjustable, when optical fibers at different angles are placed in the first mounting position 131 or the second mounting position 132, the end face of the optical fiber may not be able to be imaged completely and clearly in the microscope 141. Therefore, an angle adjustment mechanism is provided to adjust the angle of the optical fiber. Further, the angle adjustment mechanism includes a connecting seat and an adjustment drive. The third translation drive is connected to the connecting seat, and the adjustment drive is disposed in the connecting seat and connected to the connecting arm 161. Optionally, the adjustment drive is a motor. In other embodiments, the angle adjustment can be performed manually, that is, only the connecting seat is provided, the connecting seat is rotatably connected to the third translation drive, and the connecting arm 161 is connected to the connecting seat.

[0042] In one embodiment, the fiber optic end face detection device further includes a positioning element 162, which is movably connected to the displacement stage 120 and can abut against the rotating stage 130 during its movement. Thus, when the rotating stage 130 is rotated from a certain installation position to the detection position, the positioning element 162 fixes the rotating stage 130 to prevent the rotating stage 130 from rotating during the detection process.

[0043] Furthermore, the rotary table 130 has multiple positioning slots 135. During the rotation of the rotary table 130, the positioning member 162 can be inserted into the positioning slot 135, and when the positioning member 162 is inserted into any positioning slot 135, the rotary table 130 can be fixed relative to the displacement stage 120, and there is a mounting position in the detection position. In other words, the multiple positioning slots 135 correspond one-to-one with the first mounting position 131 and the second mounting position 132, thereby ensuring that when the positioning member 162 is inserted into any positioning slot 135, there is a mounting position in the detection position.

[0044] In practical applications, the rotary table 130 is rotatably connected to the end of the connecting arm 161 away from the rotary table 130 via a connecting shaft 134, while the positioning member 162 is movably connected to the connecting arm 161 and can abut against the side wall of the connecting shaft 134 during its movement. Multiple positioning slots 135 are spaced apart circumferentially on the side wall of the connecting shaft 134, so that during the rotation of the rotary table 130 and the connecting shaft 134, the positioning member 162 can be inserted into the positioning slots 135 to fix the connecting shaft 134 and the rotary table 130.

[0045] In one embodiment, the fiber optic end-face detection device further includes an elastic element. The elastic element is disposed between the displacement stage 120 and the positioning element 162, and is used to provide a force that causes the positioning element 162 to press against the rotary stage 130. Specifically, in the above embodiment, the elastic element is disposed between the connecting arm 161 and the positioning element 162, and is used to provide a force that causes the positioning element 162 to press against the connecting shaft 134.

[0046] Preferably, the positioning groove 135 extends axially along the connecting shaft 134, and the cross-section of the positioning groove 135 is arc-shaped. Thus, when the positioning member 162 is inserted into the positioning groove 135, the operator can apply external force to the rotary table 130, causing the positioning member 162 to slide out of the positioning groove 135, thereby releasing the rotary table 130 from the fixation of the positioning member 162. Optionally, the positioning member 162 and the elastic member can be elastic plungers, and the elastic plunger is threadedly connected to the connecting arm 161. Therefore, the end of the positioning member 162 that abuts against the connecting shaft 134 has an arc-shaped surface to facilitate sliding of the positioning member 162 against the side wall of the connecting shaft 134.

[0047] In one embodiment, the fiber optic end-face inspection device further includes a cleaning mechanism. The cleaning mechanism is disposed on the base 110, and the output end of the cleaning mechanism faces the mounting position rotated to the inspection position, so as to clean the end face of the fiber optic cable, thereby improving the accuracy of fiber optic end-face inspection.

[0048] In practical applications, the output end of the cleaning mechanism includes a liquid spray nozzle and an air spray nozzle. The liquid spray nozzle sprays cleaning fluid onto the end face of the optical fiber to clean it, while the air spray nozzle sprays dry gas onto the end face of the optical fiber to dry it. Optionally, the cleaning fluid sprayed by the liquid spray nozzle can be anhydrous ethanol or pure water, and the dry gas sprayed by the air spray nozzle can be dry nitrogen.

[0049] It is understandable that both the liquid spray nozzle and the air spray nozzle can be nozzles. The cleaning mechanism also includes a cleaning fluid supply module and a gas supply module. For example, the cleaning fluid supply module can be a storage tank and a delivery pump, while the gas supply module can be a high-pressure gas source. Both modules are conventional structures and will not be elaborated upon here. Furthermore, if automatic spraying of cleaning fluid and drying gas is required, a photoelectric switch or proximity switch can be set. When the photoelectric switch or proximity switch detects that the optical fiber has rotated to the detection position, the cleaning mechanism automatically sprays cleaning fluid and drying gas towards the end face of the optical fiber. Of course, to achieve automatic operation, a control mechanism is also required. The setting of the control mechanism is a conventional operation to achieve automated operation and will not be elaborated upon here.

[0050] It should be noted that the detection position is a position that can be clearly detected by the microscope 141, not a fixed position. For example, after switching to different magnification lenses 142, the displacement stage 120 adjusts the position of the optical fiber so that the microscope 141 can clearly acquire the image of the end face. At this time, the position corresponding to the mounting position is also the detection position. Meanwhile, under normal circumstances, the adjustment range of the displacement stage 120 to the position of the rotation stage 130 is small, and the cleaning fluid and drying gas sprayed by the cleaning mechanism can cover the moving optical fiber. However, the output end of the cleaning mechanism can also be manually adjusted to ensure that the cleaning fluid and drying gas are accurately sprayed onto the end face of the optical fiber at the detection position.

[0051] To facilitate understanding of the technical solution of this application, this document combines... Figure 1 The detection process of the fiber optic end-face inspection device in the above embodiments is described as follows: For optical fibers with connectors: First, connect the connector to the corresponding mounting piece 151, then connect the mounting piece 151 to the second mounting position 132 of the rotary table 130. First, select the lens 142 with the lowest magnification, and adjust the position of the optical fiber using the displacement stage 120 to center the optical fiber on the display. Adjust the angle of the optical fiber end face using the angle adjustment mechanism. Then, use the cleaning mechanism to spray cleaning fluid and drying gas sequentially onto the end face of the optical fiber to clean it, followed by inspection of the optical fiber end face. After inspection, if it is necessary to change to a different magnification lens 142, the position of the optical fiber can be adjusted again using the displacement stage 120 after changing the lens 142. After all inspections are completed, remove the mounting piece 151 from the rotary table 130.

[0052] For bare optical fiber: Install clamp 152 in the first mounting position 131, then insert the optical fiber into clamp 152, ensuring that the end of the optical fiber protrudes 3-6mm from the end face of clamp 152 in the direction of lens 142. Next, select lens 142 with the lowest magnification, and adjust the position of the optical fiber using the displacement stage 120 to center the optical fiber on the display. Adjust the angle of the optical fiber end face using the angle adjustment mechanism. Then, clean the end face of the optical fiber using the cleaning mechanism, and subsequently inspect the end face of the optical fiber. After inspection, if it is necessary to change to a different magnification lens 142, the position of the optical fiber can be adjusted again using the displacement stage 120 after changing the lens 142. After all inspections are completed, remove the optical fiber from clamp 152.

[0053] Of course, it should be noted that after replacing the lens 142 with one of higher magnification, there are situations where the fiber optic position does not need to be adjusted, and testing can be performed directly. Alternatively, the positions of the microscope 141 and lens 142 can be adjusted. For example, a slide block and a sliding drive can be installed below the microscope 141. The slide block slides on the base 110, and the sliding drive is located on the base 110 and connected to the slide block, driving the slide block to move the microscope 141 and lens 142 closer to and away from the rotating stage 130. The sliding drive can be a linear module or a cylinder. In other embodiments, the position of the slide block can also be adjusted manually.

[0054] In summary, the fiber optic end-face inspection device provided in this application has at least the following advantages: 1. By setting up multiple mounting parts 151 that can install different connectors, and each mounting part 151 is detachably connected to the second mounting position 132 of the rotary table 130, the fiber end face inspection device can inspect different types of optical fibers with connectors, without the need to set up multiple inspection devices, thus reducing equipment costs. 2. The rotary table 130 is also provided with multiple first mounting positions 131. Each first mounting position 131 can install a clamp 152, and multiple clamps 152 can position bare optical fibers of different sizes, further improving the versatility of the optical fiber end face inspection device. 3. When the rotating table 130 is rotated to the detection position from any installation position, the positioning piece 162 is inserted into the corresponding positioning groove 135 to fix the rotating table 130 relative to the displacement stage 120, thereby ensuring the stability of the rotating table 130 during the detection process, improving the clarity of the obtained image, and thus improving the accuracy of the detection. 4. By setting up a cleaning mechanism to clean the end face of the optical fiber, it is possible to avoid impurities on the end face of the optical fiber from affecting the test results, thereby improving the accuracy of the test.

[0055] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
