Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber end face detection, and more particularly to an automatic detection system for optical fiber connector surface cracks. Background Art

[0002] Fiber optic connector is a key component used to connect optical fiber lines. It can achieve efficient transmission and precise docking of optical signals and is widely used in communications, data transmission and other fields.

[0003] The inspection of optical fiber connectors, especially the inspection of surface cracks, is an important step in ensuring the quality of optical fiber communications. Traditional inspection methods usually require removing the optical fiber connector from the protective device, manually inserting it into the inspection equipment for end face crack inspection, and then manually placing it back into the protective device after the inspection is completed.

[0004] However, the existing technology has obvious shortcomings, such as low degree of automation, heavy reliance on manual operation, and low efficiency. In addition, for the convenience of detection, the optical fiber connector is often not covered and protected during detection, which leads to dust and other impurities contaminating the end face of the optical fiber connector during the detection process, affecting the detection results. The manual covering step after the detection is completed not only further reduces the degree of automation, but also increases the complexity of the operation and the risk of human error.

[0005] Therefore, in order to solve the above technical problems, the present application proposes an automatic detection system for optical fiber connector surface cracks. Summary of the Invention

[0038] like Figure 1-12 As shown, the present invention provides an automatic detection system for optical fiber connector surface cracks, including a frame 1, an end face detection device 5 is further provided on the frame 1, and an insertion port 10 is provided on the end face detection device 5. When it is necessary to detect optical fiber end face cracks, the end of the optical fiber connector 12 is inserted into the insertion port 10, and then the end face detection device 5 can detect the end face cracks of the optical fiber connector 12;

[0039] In order to automatically detect the optical fiber connector 12, the optical fiber connector surface crack automatic detection system also includes a base plate 7, a driving mechanism, and an optical fiber connector 11 arranged on the base plate 7. A plurality of optical fiber plugs are provided on the optical fiber connector 11, each of which is plugged with an optical fiber to be detected, and a feeding member is provided between the optical fiber connector 11 and the driving mechanism. When the driving mechanism is started, the feeding member moves the optical fiber connector 11 toward the end face detection device 5. In the above, the driving mechanism and the feeding member are provided to realize the automatic movement of the optical fiber on the optical fiber connector 11 to the end face detection device 5;

[0040] In one embodiment of the present invention, the driving mechanism includes a driving motor 2 mounted on a frame 1, and a track 22 mounted on the frame 1. A sliding block 21 is provided on the track 22. A crank 23 connected to the sliding block 21 is mounted on the driving end of the driving motor 2. By starting the driving motor 2, the sliding block 21 is caused to reciprocate on the track 22 via the crank 23.

[0041] In another embodiment of the present invention, the feeding member includes a conveyor belt 3 installed on the base plate 7, and a plurality of pressure plates 33 are arranged at equal intervals on the belt surface of the conveyor belt 3. The ends of the pressure plates 33 are installed with inclined plates 32, and the inclined plates 32 can only rotate in one direction. The unidirectionally rotating inclined plates 32 can be installed on the ends of the pressure plates 33 by a one-way shaft, or can be directly rotated by the rotating shaft and set at the ends of the pressure plates 33, and then the inclined plates 32 are resisted by the limit plates, so that the inclined plates 32 can only rotate in one direction. The above unidirectionally rotating installation methods of the inclined plates 32 are all existing technologies and will not be described in detail. Here, after starting the driving motor 2 in the driving mechanism, the conveyor belt 3 is synchronously driven to rotate by the driving motor 2. The feeding member also includes a telescopic rod 3 4 provided on the sliding block 21, and a resistance push plate 41 is also provided on the telescopic rod 3 4. The optical fiber connector 11 is slidably connected to the base plate 7. The optical fiber connector 12 to be tested is plugged into the optical fiber connector 11 together with the protective cover, and the optical fiber connector 11 with the optical fiber connector 12 plugged in is placed on the base plate 7, and the end of the optical fiber connector 11 is abutted against the surface of the driving plate 31 provided on the conveyor belt 3. Then, the driving motor 2 is started and the sliding block 21 is reciprocated, thereby causing the telescopic rod 3 4 and the resistance push plate 41 to reciprocate. When the resistance push plate 41 reciprocates, the resistance push plate 41 pushes the inclined plate 32 and the pressure plate 33, thereby pushing the conveyor belt 3 to move.

[0042] It should be noted here that each time the push plate 41 pushes the inclined plate 32 and the pressure plate 33 to move the conveyor belt 3 a distance of one station, that is, the distance between each adjacent optical fiber connector 12 on the optical fiber connector 11, and when the optical fiber connector 11 is placed on the bottom plate 7, its position needs to correspond to the plug interface 10 of the end face detection device 5, so that after the conveyor belt 3 rotates one station, the port of the first optical fiber connector 12 on the optical fiber connector 11 is directly opposite to the plug interface 10. Similarly, this has certain requirements on the length of the conveyor belt 3, and the length of the conveyor belt 3 needs to be The length of the optical fiber connector 11 is an integer multiple of the length of the optical fiber connector 11, and the spacing size of adjacent driving plates 31 also needs to be the same as the length of the optical fiber connector 11. In this way, after the optical fiber connector 11 is pushed by the driving plate 31 to check all the optical fiber connectors 12 thereon, another driving plate 31 is moved to the initial position. At this time, another optical fiber connector 11 can be directly placed against the surface of the driving plate 31. In this way, when installing the optical fiber connector 11, the installation is more convenient, and it is not necessary to adjust the position of the optical fiber connector 11 each time to adapt to the distance between the first optical fiber connector 12 thereon and the plug-in port 10;

[0043] When the push plate 41 is moved back to its original position, the inclined plate 32 is pressed against the inclined plate 32 and the inclined plate 32 is separated from the inclined plate 32, and the inclined plate 32 is restored to its original position. At this time, if the push plate 41 is used to push the inclined plate 32 and the pressure plate 33 again to make the conveyor belt 3 rotate again, the push plate 41 can be pressed against the surface of the next inclined plate 32 without causing a gap between the push plate 41 and the inclined plate 32, so as to meet the overall use.

[0044] It should also be noted that the optical fiber connector 11 is made of a plate with sockets provided at equal intervals. When installing the optical fiber connector 12, the optical fiber connector 12 together with the protective cover is plugged into the sockets provided on the optical fiber connector 11. This is prior art and will not be described in detail.

[0045] When the optical fiber connector 11 moves on the base plate 7, in order to automatically pull out the optical fiber connector 12 from the protective cover on the optical fiber connector 11 and plug it into the plug-in port 10 on the end face detection device 5, and after the detection is completed, the optical fiber connector 12 that has been tested is plugged back into the corresponding protective cover on the optical fiber connector 11, the optical fiber connector surface crack automatic detection system also includes a clamping plate 85, which is connected to the driving mechanism through a clamping mechanism, and the clamping mechanism is installed on the guide mechanism. When the optical fiber connector 11 moves to the point where the optical fiber connector 12 is in the same position as the plug-in port 10 of the end face detection device 5, the clamping plate 85 is connected to the driving mechanism through a clamping mechanism. When the optical fiber connector 12 is on a flat surface, the clamping mechanism is used to realize the clamping plate 85 to clamp the optical fiber connector 12 on the optical fiber connector 11, and after clamping, the guide mechanism is used to make the clamping plate 85 perform two actions. The first action is: the clamping plate 85 makes the optical fiber connector 12 away from the optical fiber connector 11 and rises to the same height as the plug-in interface 10 of the end face detection device 5 and then plugs it into the plug-in interface 10. The second action is: the clamping plate 85 makes the optical fiber connector 12 away from the plug-in interface 10 and lowers it back to the same height as the optical fiber connector 11 and then re-plugs it into the optical fiber connector 11. In this way, when the optical fiber connector 11 moves on the base plate 7, it is also clamped by the provided clamping claws. The mechanism and the guide mechanism enable the clamping plate 85 and the optical fiber connector 12 to have two motion strokes, thereby automatically pulling out the optical fiber connector 12 from the protective cover on the optical fiber plug-in part 11 and plugging it into the plug-in interface 10 on the end face detection device 5, and after the detection is completed, the optical fiber connector 12 that has been tested is plugged back into the corresponding protective cover on the optical fiber plug-in part 11. The whole process does not require manual operation and has a high degree of automation. When the optical fiber connector 12 is plugged into the optical fiber plug-in part 11, it is in the protective cover. During the detection, the clamping plate 85 takes it out of the protective cover and plugs it into the plug-in interface 10, and then the detection is completed. After completion, the optical fiber connector 12 is returned to its original path and re-inserted into the corresponding protective cover in the optical fiber connector 11. Before the test, the end of the optical fiber connector 12 is protected by the protective cover. After the test is completed, the protective cover can be automatically inserted back to protect the end of the optical fiber connector 12. This operation does not require manual operation, which further improves the overall automation effect. In addition, the cover is automatically removed before the test to prevent dust from contaminating the end face of the optical fiber connector 12 and causing the problem of test failure, thereby improving the accuracy of the test. In addition, there is no need to manually open and close the cover of the optical fiber connector 12, and the test operation is more convenient as a whole.

[0046] In one embodiment of the present invention, the clamping mechanism includes an abutment plate 8 mounted on the driving mechanism and a hollow shell 6 arranged on the frame 1, two sets of mutually symmetrical wedge blocks 84 are arranged on the inner side of the hollow shell 6, and a connecting rod 81 with a ball 82 is arranged between the two wedge blocks 84, and the end of the connecting rod 81 is slidably arranged on an arc seat 1 812, and the arc seat 1 812 is slidably arranged with the inner wall of the hollow shell 6, and the clamping plate 85 is fixed on the connecting rod 81. When the abutment plate 8 moves close to the arc seat 1 812 through the driving mechanism, the abutment plate 8 abuts against the arc-shaped outer surface of the arc seat, and the sliding block 21 is reciprocated on the track 22 by starting the driving motor 2. Since the abutment plate 8 is arranged on the sliding block 21, the abutment plate 8 will move with the sliding block 21, thereby squeezing the arc seat 1 812 through the abutment plate 8, and the arc seat 1 812 moves downward, thereby squeezing the ball 82 through the wedge block 84. At this time, the two The connecting rod 81 and the clamping plate 85 are close to each other, and as the arc seat 1 812 moves downward, the two clamping plates 85 move downward and approach each other at the same time. After the abutment plate 8 squeezes the arc seat 1 812 and moves downward to the maximum stroke, the two clamping plates 85 approach each other to the maximum stroke. At this time, the two clamping plates 85 clamp the outer surface of the optical fiber connector 12, and the clamping claw mechanism also includes a baffle 811 fixed to the hollow shell 6, forming a groove 810 between the baffle 811 and the arc seat 1 812, and the size of the groove 810 and the abutment plate 8 are adapted to each other. In this way, after the optical fiber connector 12 is clamped by the two clamping plates 85, the sliding block 21 has not moved to the maximum stroke, driving the abutment plate 8 to continue moving and abut against the baffle 811, and then pushing the hollow shell 6 to move on the frame 1, so that the end of the optical fiber connector 12 can be pulled out from the optical fiber plug-in component 11 by clamping the optical fiber connector 12 by the clamping plate 85;

[0047] After the optical fiber connector 12 is pulled out from the corresponding protective shell on the optical fiber connector 11, the optical fiber connector 12 is raised to a certain height and staggered from the original position, so that the pulled-out optical fiber connector 12 can be inserted into the plug interface 10 on the end face detection device 5 for detection. In another embodiment of the present invention, the guide mechanism includes a side plate 87 mounted on the frame 1, and a guide groove 813 is installed on the side plate 87. A mounting seat 88 is tilted and slidably engaged in the guide groove 813. The mounting seat 88 is connected to the hollow shell 6. When the abutment plate 8 pushes the baffle 811 and causes the hollow shell 6 to displace, The guide groove 813 is used to enable the mounting seat 88 to drive the hollow shell 6 to move obliquely upward. When the optical fiber connector 12 is pulled out of the optical fiber plug-in component 11 by the clamping plate 85, the abutting push plate 41 and the baffle 811 cause the hollow shell 6 to continue to move. At this time, the mounting seat 88 is limited by the guide groove 813 and begins to move obliquely upward. At this time, the entire hollow shell 6 moves obliquely upward, thereby causing the hollow shell 6 to move obliquely upward with the clamping plate 85 and the optical fiber connector 12 until the sliding block 21 moves to its maximum stroke. At this time, the height of the optical fiber connector 12 is the same as the height of the insertion port 10 of the end face detection device 5.

[0048] At this time, the driving motor 2 is in a continuous starting state. At this time, the sliding block 21 runs to the maximum stroke and starts to move in the reverse direction under the action of the crank 23. Figure 8 and Figure 10The cam 810 is then engaged with the support 811 and the support 812, and the support 810 is engaged with the support 813. When the fiber connector 12 is inserted into the insertion port 10 on the end face detection device 5, the end face detection device 5 can be used to detect the end face cracks of the optical fiber connector 12. Here, when the abutment plate 8 pushes the baffle 811, the arc seat 1 812 is smooth and unobstructed. When the abutment plate 8 moves in the reverse direction, if it is necessary to enable it to push the hollow shell 6 in the reverse direction to move, it is undoubtedly necessary to use a locking member to lock the abutment plate 8 with the baffle 811 or the arc seat 1 812. In this solution, the mounting seat 88 moves upward along the guide groove 813, so that the hollow shell 6 moves upward as a whole, thereby realizing self-locking of the abutment plate 8 through the groove 810, so that it can drive the reverse movement of the hollow shell 6 when it moves in the reverse direction. There is no need to set an additional self-locking mechanism, which reduces the complexity of the structure and has a better use effect.

[0049] It should be noted here that, since the driving motor 2 controls the sliding block 21 to move back and forth through the crank 23, the stroke is the same. However, since the sliding block 21 undergoes horizontal movement and tilting movement limited by the guide groove 813, and since the horizontal movement distances of the tilting movement and the horizontal movement are different, it is necessary to compensate for the different movement distances by adjusting the position of the plug interface 10 on the end face detection device 5, so that when the sliding block 21 moves horizontally in the reverse direction, the port of the optical fiber connector 12 can be plugged into the plug interface 10 through the hollow shell 6 and the clamping plate 85. This can also be simply achieved by existing technical means, and the details will not be repeated here.

[0050] After the detection is completed, the driving motor 2 is started again, and the sliding block 21 enters the second movement stroke through the crank 23. In order to be able to reinsert the optical fiber connector 12 after the detection into the corresponding protective shell in the optical fiber connector 11 during this movement stroke, in another embodiment of the present invention, please refer to Figure 10 and Figure 11, a steering mechanism is also rotatably provided on the side plate 87. When the mounting seat 88 slides in the guide groove 813, the steering mechanism is used to switch the mounting seat 88 between the horizontal movement and the tilting movement. By setting the steering mechanism, when the sliding block 21 enters the second stroke, the mounting seat 88 can be returned to the inclined section of the guide groove 813, so that the optical fiber connector 12 after detection can be lowered to the initial position (the same height as the plug-in interface 10 of the optical fiber connector 11). In this way, the two strokes of the sliding block 21 driven by the driving motor 2 are different, so that the optical fiber connector 12 can be pulled out from the optical fiber connector 11 and raised to the same height as the plug-in interface 10, plugged into the plug-in interface 10 for end face detection, pulled out from the plug-in interface 10, lowered and re-plugged into the optical fiber connector 11 through the drive of the same driving motor 2. Multiple processes, without manual intervention, the whole process is automatically carried out, the overall use is relatively convenient, and there is no need for multiple cylinders to cooperate to achieve multiple strokes, and the overall installation is also relatively convenient;

[0051] In one embodiment of the present invention, the steering mechanism includes a guide rotating plate 816 rotatably arranged on the side plate 87, one side of the guide rotating plate 816 protrudes outward, and an L-shaped plate 819 is installed on the guide rotating plate 816 through a second spring 817. The L-shaped plate 819 is inserted into the hole on the surface of the guide groove 813. When the mounting seat 88 moves upward along the guide groove 813, a telescopic rod 814 is provided on the mounting seat 88 at the position of the "L"-shaped short side corresponding to the L-shaped plate 819, and the guide rotating plate 816 is rotatably connected to the side plate 87 through a torsion spring, and a channel is formed between the outwardly protruding part of the guide turntable and the guide groove 813, and the formed channel gap is greater than There is a gap in the guide groove 813, so that when the mounting seat 88 moves upward, the mounting seat 88 passes over the L-shaped plate 819. The end of the second telescopic rod 814 provided here can be elastically extended (elastic telescopic rod). At this time, the telescopic end of the second telescopic rod 814 pops outward and abuts against the L-shaped plate 819. At this time, as the mounting seat 88 moves, the L-shaped plate 819 separates from the hole on the surface of the guide groove 813. At this time, as the mounting seat 88 continues to move and the torsion spring acts, the guide rotating plate 816 is attached to the surface of the mounting seat 88 and gradually rotates until the mounting seat 88 and the guide rotating plate 816 are completely separated. At this time, the guide rotating plate 816 returns to the non-deformed position of the torsion spring.

[0052] As the sliding block 21 moves in the reverse direction, see Figure 8, the movement of the abutment plate 8 causes the hollow shell 6 to move in the opposite direction. At this time, the mounting seat 88 moves in the opposite direction until it abuts against the guide rotating plate 816. Since the guide plate is not locked, it rotates counterclockwise. Then the mounting seat 88 disengages from the guide rotating plate 816, and the guide rotating plate 816 returns to its original position until the mounting seat 88 moves to the maximum stroke. The optical fiber connector 12 is plugged into the plug interface 10. Then, after the inspection is completed, it enters the second stroke of the sliding block 21. The mounting seat 88 moves horizontally toward the guide rotating plate 816 until the guide rotating plate 816 is pushed. After the guide rotating plate 816 rotates, the L-shaped plate 819 is re-inserted into the hole of the guide groove 813. At this time, the guide rotating plate 816 is fixed, and the height of the outward protrusion on it is higher than the horizontal section of the guide groove 813. At this time, the sliding seat and the abutment Driven by the plate 8, the mounting seat 88 moves in the opposite direction again. At this time, the mounting seat 88 is counteracted by the outward protrusion of the guide rotating plate 816. The outward protrusion of the guide rotating plate 816 guides the mounting seat 88 and guides the mounting seat 88 downward into the oblique section of the guide groove 813. At this time, the mounting seat 88 and the hollow shell 6 move downward to the initial position. At this time, the height of the optical fiber connector 12 is the same as the height of the optical fiber connector 11. Then the mounting seat 88 is separated from the oblique section of the guide groove 813. The mounting seat 88 undergoes another horizontal movement. At this time, the optical fiber connector 12 is reinserted into the optical fiber connector 11. The wire rotating plate provided can enable the mounting seat 88 to have two different motion states and switch between the two motion states to realize the automated detection operation of the optical fiber connector 12.

[0053] It should be noted that when the L-shaped plate 819 on the guide rotating plate 816 moves close to the hole, the L-shaped plate 819 will first contact the surface of the guide groove 813. The contact position here needs to be set to a smooth curved surface to prevent the spring 2 817 on the L-shaped plate 819 from being unable to deform and causing the L-shaped plate 819 to be locked. Similarly, when the L-shaped plate 819 is inserted into the hole in the guide groove 813, the gap between the guide rotating plate 816 and the guide groove 813 needs to be smaller than the width of the telescopic rod 2 814 to prevent the telescopic rod 2 814 from being inserted into the gap and causing it to be stuck. In addition, when the telescopic rod 2 814 transitions from the guide groove 813 to the locked guide rotating plate 816 position, the contact position of the telescopic end position of the telescopic rod 2 814 should also be set to a smooth curved surface, also to prevent the telescopic rod 2 814 from being stuck.

[0054] Here, an extension plate 818 can be provided on the guide rotating plate 816 to reduce the distance between the guide rotating plate 816 and the guide groove 813, thereby facilitating the passage of the second telescopic rod 814. The extension plate 818 can also reduce the transition width between the guide groove 813 and the guide rotating plate 816, thereby further improving the passability.

[0055] It should also be noted that the connection position of the second telescopic rod 814 on the mounting seat 88 is set away from the position of the L-shaped plate 819 to prevent the mounting seat 88 from abutting against the end of the L-shaped plate 819 before the mounting seat 88, thereby preventing the mounting seat 88 and the guide rotating plate 816 from getting stuck.

[0056] In order to separate the clamping plate 85 from the optical fiber connector 12 when the optical fiber connector 12 is reinserted into the optical fiber connector 11, the optical fiber connector surface crack automatic detection system further includes an arc seat 2 91 slidably arranged on the hollow shell 6, and a top plate 9 is provided on the arc seat 2 91, and the top plate 9 abuts against the upper surface of the through groove of the connecting plate between the two clamping plates 85, and the arc of the arc seat 1 812 and the arc outer surface of the arc seat 2 91 are the same. When the optical fiber connector 12 is reinserted into the optical fiber connector 11 through the clamping plate 85, the entire hollow shell 6 will move downward to the initial position, at which time the abutment plate 8 is separated from the groove 810 and abutted. The plates 8 are contact-limited, and when the abutting plate 8 moves in the reverse direction, it pushes the arc seat 2 91, causing the arc seat to move upward, thereby pushing the clamping plate 85 upward through the top plate 9, and the clamping plate 85 moves upward. A spring 1 83 is provided between the two clamping plates 85. When the two clamping plates 85 move upward until the ball 82 contacts the inclined surface of the wedge plate, the spring 1 83 recovers its deformation, and the two connecting rods 81 separate from each other, thereby causing the two clamping plates 85 to separate from each other, releasing the clamping of the optical fiber connector 12. The arc outer surfaces of the arc seat 1 812 and the arc seat 2 91 have the same curvature, and when squeezed by the abutting plate 8, the rising and falling distances are the same.

[0057] In summary, the following explanation is required. When the optical fiber connector 12 is inspected, the entire optical fiber connector 12 has four motion states under the clamping of the clamping plate 85, that is, the driving motor 2 needs to drive the crank 23 to rotate two cycles, and the sliding block 21 will also move back and forth twice at this time. However, in this process, only the conveyor belt 3 needs to move one station. Therefore, a telescopic rod 1 89 is further provided between the mounting seat 88 and the telescopic end of the telescopic rod 3 4. In this way, when the mounting seat 88 rises, the telescopic rod 3 4 will be pulled upward by the telescopic rod 1 89, and the telescopic rod 1 89 will shrink. In this way, when the entire inspection process is carried out to the point where the optical fiber connector 12 is pulled out from the plug port 10, due to the height of the telescopic plate 3, the telescopic rod 3 4 will shrink. The resistance push plate 41 on the three telescopic ends of the retracting plate will not come into contact with the inclined plate 32 and the pressure plate 33, so that the conveyor belt 3 will not move until all four motion states are completed, that is, after one detection is completed, the conveyor belt 3 will be moved one station again, and it will be reciprocated in this way, so that the automatic detection of the optical fiber connector 12 can be realized. Moreover, through the same drive motor 2, not only can the mounting seat 88 have two different motion states, so that the optical fiber connector 12 can have different motion strokes to realize automatic detection, but also the conveyor belt 3 can cooperate with the detection process of the optical fiber connector 12 to intermittently feed the optical fiber connector 12. It has a high degree of automation, does not require manual operation, and has excellent use effect.
