Description

Technical Field

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

[0002] An optical fiber connector is a key component for connecting optical fiber lines, which can achieve efficient transmission and precise docking of optical signals, and is widely used in fields such as communication and data transmission.

[0003] For the detection of optical fiber connectors, especially the detection of surface cracks, is an important link to ensure the quality of optical fiber communication. Traditional detection methods usually require removing the optical fiber connector from the protection device, manually inserting it into the detection device for end face crack detection, and then manually putting it back into the protection device after the detection is completed.

[0004] However, the existing technology has obvious disadvantages, such as low automation, heavy dependence on manual operation, and low efficiency. In addition, for the convenience of detection, the optical fiber connector is often not covered during detection, which may cause dust and other impurities to contaminate the end face of the optical fiber connector during the detection process, affecting the detection result. And the manual covering step after the detection not only further reduces the automation degree, but also increases the operation complexity 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 surface cracks of an optical fiber connector. Summary of the Invention

The automatic detection system for surface cracks of the optical fiber connector further includes: A bottom plate, a driving mechanism, and an optical fiber plug-in member provided on the bottom plate. A feeding member is provided between the optical fiber plug-in member and the driving mechanism. When the driving mechanism is started, the optical fiber plug-in member is moved in the direction close to the end face detection device through the feeding member; The clamping plate is connected to the driving mechanism through a clamping claw mechanism, and the clamping claw mechanism is installed on the guiding mechanism. When the optical fiber connector moves to make the optical fiber connector and the end face detection device plug-in interface in the same plane, the clamping claw mechanism is used to realize the clamping plate to clamp the optical fiber connector on the optical fiber connector, and after clamping, the guiding mechanism is used to make the clamping plate realize two actions. The first action is that the clamping plate moves the optical fiber connector away from the optical fiber connector and rises to the same height as the plug-in interface of the end face detection device, and then plugs it into the plug-in interface. The second action is that the clamping plate moves the optical fiber connector away from the plug-in interface and descends back to the same height as the optical fiber connector, and then re-plugs it into the optical fiber connector.

[0018] 2. Protect the fiber optic connector: Before detection, the fiber optic connector is in the protective cover.

[0023] like Figures 1-12 As shown, the present invention provides an automatic detection system for cracks on the surface of an optical fiber connector, comprising a frame 1, an end face detection device 5 is also arranged on the frame 1, and an insertion port 10 is arranged on the end face detection device 5. When it is necessary to detect cracks on the end face of the optical fiber, the end of the optical fiber connector 12 is plugged into the insertion port 10, and then the end face cracks on the end face of the optical fiber connector 12 can be detected by the end face detection device 5; In order to realize automatic detection of 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 arranged on the optical fiber connector 11, and an optical fiber to be detected is plugged into each optical fiber plug, and a feeding member is arranged between the optical fiber connector 11 and the driving mechanism. When the driving mechanism is started, the optical fiber connector 11 is moved toward the end face detection device 5 by the feeding member. In the above, the optical fiber on the optical fiber connector 11 is automatically moved to the end face detection device 5 by the arranged driving mechanism and feeding member; In an embodiment of the present invention, the driving mechanism includes a driving motor 2 installed on the frame 1, and a track 22 installed on the frame 1. A sliding block 21 is arranged on the track 22. A crank 23 connected to the sliding block 21 is installed on the driving end of the driving motor 2. By starting the driving motor 2, the sliding block 21 makes a reciprocating motion on the track 22 via the crank 23; In another embodiment of the present invention, the feeding member includes a conveyor belt 3 installed on the bottom plate 7. A plurality of pressure-receiving plates 33 are arranged in an equidistant array on the belt surface of the conveyor belt 3. Oblique plates 32 are installed at the ends of the pressure-receiving plates 33, and the oblique plates 32 can only rotate unidirectionally. The unidirectionally rotating oblique plates 32 can be installed at the ends of the pressure-receiving plates 33 through a one-way shaft, or can be directly rotatably arranged at the ends of the pressure-receiving plates 33 through a rotating shaft, and then the oblique plates 32 are abutted by a limiting plate, so that the oblique plates 32 can only rotate unidirectionally. The above installation methods for the unidirectional rotation of the oblique plates 32 are all prior arts and will not be elaborated 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 further includes a third telescopic rod 4 arranged on the sliding block 21, and a pushing plate 41 is arranged on the third telescopic rod 4. The optical fiber connector 11 is slidably connected to the bottom plate 7. The optical fiber connector 12 to be detected together with the protective cover is inserted into the optical fiber connector 11, and the optical fiber connector 11 inserted with the optical fiber connector 12 is placed on the bottom plate 7, and the end of the optical fiber connector 11 is abutted against the surface of a driving plate 31 arranged on the conveyor belt 3. Then the driving motor 2 is started and the sliding block 21 makes a reciprocating motion, so that the third telescopic rod 4 and the pushing plate 41 make a reciprocating motion. When the pushing plate 41 makes a reciprocating motion, the oblique plates 32 and the pressure-receiving plates 33 are pushed by the pushing plate 41, so as to push the conveyor belt 3 to move; It should be noted here that each time the abutting push plate 41 pushes the inclined plate 32 and the pressure receiving plate 33 to move the conveyor belt 3, the moving distance is one station, that is, the distance between adjacent optical fiber connectors 12 on the optical fiber plug-in unit 11. And when the optical fiber plug-in unit 11 is placed on the bottom plate 7, its position needs to correspond to the insertion port 10 of the end face detection device 5. After the conveyor belt 3 rotates one station, the port of the first optical fiber connector 12 on the optical fiber plug-in unit 11 is directly opposite to the insertion port 10. Similarly, this places certain requirements on the length of the conveyor belt 3. The length of the conveyor belt 3 needs to be an integer multiple of the length of the optical fiber plug-in unit 11, and the spacing dimension between adjacent driving plates 31 also needs to be the same as the length of the optical fiber plug-in unit 11. In this way, after all the optical fiber connectors 12 on the optical fiber plug-in unit 11 are inspected by pushing the optical fiber plug-in unit 11 by the driving plate 31, another driving plate 31 moves to the initial position. At this time, another optical fiber plug-in unit 11 can be directly placed against the surface of the driving plate 31. In this way, when installing the optical fiber plug-in unit 11, the installation is relatively convenient, and it is not necessary to adjust the position of the optical fiber plug-in unit 11 each time to adapt to the distance between the first optical fiber connector 12 on it and the insertion port 10; It should also be noted that among multiple groups of pressure receiving plates 33 and inclined plates 32, there is an overlapping part between the end of the resting plate and the adjacent pressure receiving plate 33 in a top view. When the abutting push plate 41 rotates the conveyor belt 3 by pushing the inclined plate 32 and the pressure receiving plate 33, at this time, due to the one-way rotation setting of the inclined plate 32, the conveyor belt 3 advances one station. When the abutting push plate 41 retracts to the initial position, the abutting push plate 41 will abut against the inclined plate 32 during movement, causing the inclined plate 32 to rotate until the abutting push plate 41 crosses the inclined plate 32 and separates from the inclined plate 32. At this time, the inclined plate 32 returns to its original position. When the conveyor belt 3 is rotated again by pushing the inclined plate 32 and the pressure receiving plate 33 by the abutting push plate 41 at this time, the abutting push plate 41 can abut against the surface of the next inclined plate 32 without causing a gap between the abutting push plate 41 and the inclined plate 32, so as to meet the overall use; It should also be noted that the optical fiber plug-in unit 11 is made of a plate, and sockets are equally spaced on the plate. When installing the optical fiber connector 12, the optical fiber connector 12 together with the protective cover can be inserted into the sockets opened on the optical fiber plug-in unit 11. This is the prior art and will not be elaborated; When the optical fiber connector 11 moves on the bottom 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 make the optical fiber connector 12 and the plug-in port 10 of the end face detection device 5 in the same position, the clamping plate 85 is connected to the driving mechanism through a clamping mechanism. When the optical fiber connector 12 is on a plane, the clamping claw 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 guiding mechanism is used to make the clamping plate 85 realize two actions, the first action: 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 port 10 of the end face detection device 5 and then plugs it into the plug-in port 10, the second action: the clamping plate 85 makes the optical fiber connector 12 away from the plug-in port 10 and descends back to the same height as the optical fiber connector 11 and then re-plugs it into the optical fiber connector 11, so that when the optical fiber connector 11 moves on the bottom plate 7, it also passes through the set clamping claws The mechanism and the guide mechanism enable the clamping plate 85 and the optical fiber connector 12 to have two movement strokes, so as 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 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 connector 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 connector 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 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 detection, the end of the optical fiber connector 12 is protected by the protective cover. After the detection 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 of use. In addition, the cover is automatically removed before the detection to prevent dust from contaminating the end face of the optical fiber connector 12 and causing the problem of detection failure, thereby improving the accuracy of the detection. In addition, there is no need to manually open and close the cover of the optical fiber connector 12, and the detection operation is more convenient as a whole. In an embodiment of the present invention, the jaw mechanism includes an abutting plate 8 mounted on a driving mechanism and a hollow shell 6 provided on a frame body 1. Two groups of symmetrically arranged wedge blocks 84 are provided inside the hollow shell 6. A connecting rod 81 with a ball 82 mounted between the two wedge blocks 84 is provided. The end of the connecting rod 81 is slidably arranged on an arc-shaped seat one 812. The arc-shaped seat one 812 is slidably arranged with the inner wall of the hollow shell 6. A clamping plate 85 is fixedly connected to the connecting rod 81. When the driving mechanism makes the abutting plate 8 move closer to the arc-shaped seat one 812, the abutting plate 8 abuts against the arc-shaped outer surface of the arc-shaped seat. By starting the driving motor 2, the sliding block 21 reciprocates on the track 22. Since the abutting plate 8 is arranged on the sliding block 21, at this time, the abutting plate 8 will move together with the sliding block 21. Thus, the arc-shaped seat one 812 is squeezed by the abutting plate 8, and the arc-shaped seat one 812 moves downward. Thus, the ball 82 is squeezed by the wedge block 84. At this time, the two connecting rods 81 and the clamping plate 85 approach each other. And because the arc-shaped seat one 812 moves downward, the two clamping plates 85 move downward and approach each other simultaneously. After the abutting plate 8 squeezes the arc-shaped seat one 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 fiber optic connector 12. The jaw mechanism further includes a baffle 811 fixedly connected to the hollow shell 6. A groove 810 is formed between the baffle 811 and the arc-shaped seat one 812. The size of the groove 810 is adapted to that of the abutting plate 8. After the fiber optic connector 12 is clamped by the two clamping plates 85, at this time, the sliding block 21 has not moved to the maximum stroke. The abutting plate 8 is driven to continue moving and abuts against the baffle 811. Then, the hollow shell 6 is pushed to move on the frame body 1. In this way, the end of the fiber optic connector 12 can be pulled out from the fiber optic plug 11 by clamping the fiber optic connector 12 with the clamping plate 85; After the fiber optic connector 12 is pulled out from the corresponding protective housing on the fiber optic connector 11, the fiber optic connector 12 is raised to a certain height and displaced from its original position, so as to facilitate inserting the pulled-out fiber optic connector 12 into the insertion port 10 on the end face detection device 5 for detection. In another embodiment of the present invention, the guiding mechanism includes a side plate 87 mounted on the frame body 1, and a guiding groove 813 is mounted on the side plate 87. The guiding groove 813 is inclined and slidably fitted with a mounting seat 88, and the mounting seat 88 is connected to the hollow shell 6. When the abutting plate 8 pushes the baffle 811 and causes the hollow shell 6 to displace, the guiding groove 813 is used to drive the mounting seat 88 to drive the hollow shell 6 to move obliquely upward. When the fiber optic connector 12 is pulled out from the fiber optic connector 11 by the clamping plate 85, at this time, the abutting push plate 41 and the baffle 811 that are in contact make the hollow shell 6 continue to move. At this time, the mounting seat 88 is limited by the guiding groove 813 and begins to move obliquely upward. At this time, the overall hollow shell 6 moves obliquely upward, so that the hollow shell 6 drives the clamping plate 85 and the fiber optic connector 12 to move obliquely upward together until the sliding block 21 moves to the maximum stroke. At this time, the height of the fiber optic connector 12 is the same as the height of the insertion port 10 of the end face detection device 5; 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. Please refer to Figure 8 and Figure 10, due to the upward movement of the hollow shell 6, a groove 810 is formed between the baffle 811 and the arc seat 812. The size of the groove 810 is adapted to that of the abutting plate 8. Also, since the depth of the groove 810 is set to be the same as the height dimension of the mounting seat 88 sliding upward along the inclined guide groove 813 to the maximum stroke, at this time, due to the overall upward movement of the hollow shell 6 and the fixed length of the abutting plate 8, the abutting plate 8 is clamped into the groove 810. Therefore, when the abutting plate 8 starts to move in the reverse direction, the groove 810 limits the abutting plate 8 at this time. At this time, the abutting plate 8 starts to make the entire hollow shell 6 move in the reverse direction by pushing the plane position of the arc seat 812. And since the mounting seat 88 is no longer engaged with the inclined section of the guide groove 813 at this time, the hollow shell 6 makes a horizontal movement until the hollow shell 6 drives the clamping plate 85 to move in the reverse direction to insert the fiber optic connector 12 into the insertion port 10 on the end face detection device 5. At this time, the end face crack of the fiber optic connector 12 can be detected by the end face detection device 5. Here, when the abutting plate 8 pushes the baffle 811, the arc seat 812 is smooth and unobstructed. When the abutting plate 8 moves in the reverse direction, if it is necessary to make it push the hollow shell 6 to move in the reverse direction, it is undoubtedly necessary to use a locking member to lock the abutting plate 8 with the baffle 811 or the arc seat 812. In this solution, the upward inclined movement of the mounting seat 88 along the guide groove 813 makes the hollow shell 6 move upward as a whole, thereby realizing self-locking of the abutting plate 8 through the groove 810, enabling it to drive the reverse movement of the hollow shell 6 when moving in the reverse direction, without the need to additionally set a self-locking mechanism, reducing the structural complexity and having a better use effect; It should be noted here that although the driving motor 2 controls the reciprocating movement stroke of the sliding block 21 through the crank 23 to be the same, since the sliding block 21 will undergo horizontal movement and inclined movement limited by the guide groove 813, and the moving distances of the inclined movement and the horizontal movement in the horizontal direction are different, at this time, it is necessary to adjust the position of the insertion port 10 on the end face detection device 5 to compensate for this different moving distance, so that when the sliding block 21 moves horizontally in the reverse direction, the fiber optic connector 12 port can be inserted into the insertion port 10 through the hollow shell 6 and the clamping plate 85. This can also be simply achieved by existing technical means and will not be elaborated here; After the detection is completed, the driving motor 2 is started again. Through the set crank 23, the sliding block 21 enters the second movement stroke. In order to be able to reinsert the detected fiber optic connector 12 into the corresponding protective shell in the fiber optic connector 11 in this movement stroke, in another embodiment of the present invention, please refer to Figure 10 and Figure 11, a steering mechanism is also rotatably arranged 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 a horizontal movement state and an inclined movement state. By means of the provided steering mechanism, when the sliding block 21 enters the second stroke, the mounting seat 88 can return to the inclined section of the guide groove 813 again, so that the detected optical fiber connector 12 can be lowered to the initial position (the same height as the insertion port 10 of the optical fiber connector 11). In this way, the routes of the two strokes of the driving motor 2 driving the sliding block 21 are made different. Thus, through the driving of the same driving motor 2, the optical fiber connector 12 can go through multiple processes of being pulled out from the optical fiber connector 11, rising to the same height as the insertion port 10, being inserted into the insertion port 10 for end face detection, being pulled out from the insertion port 10, lowering the height and being re-inserted back into the optical fiber connector 11. Without manual intervention, the whole process is automatically carried out, which is relatively convenient to use as a whole. And there is no need for multiple cylinders to cooperate to achieve multiple strokes, and the overall installation is also relatively convenient; In an 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 bulges outwards, 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 a hole on the surface of the guide groove 813. When the mounting seat 88 moves obliquely upwards along the guide groove 813, a second telescopic rod 814 is arranged at the position corresponding to the short side of the "L" shape of the L-shaped plate 819 on the mounting seat 88. The guide rotating plate 816 is rotationally connected to the side plate 87 through a torsion spring, and a channel is formed between the bulging part of the guide rotating disc and the guide groove 813. The clearance of the formed channel is larger than the clearance of the guide groove 813. In this way, when the mounting seat 88 moves obliquely upwards, 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 outwards and abuts against the L-shaped plate 819. At this time, as the mounting seat 88 moves, the L-shaped plate 819 is separated from the hole on the surface of the guide groove 813. At this time, with the continuous movement of the mounting seat 88 and the action of the torsion spring, the guide rotating plate 816 gradually rotates while sticking to the surface of the mounting seat 88 until the mounting seat 88 is completely separated from the guide rotating plate 816. At this time, the guide rotating plate 816 returns to the non-deformed position of the torsion spring; As the sliding block 21 moves in the reverse direction, please refer to Figure 8, the movement of the abutting plate 8 causes the hollow shell 6 to move in the reverse direction. At this time, the mounting seat 88 moves in the reverse direction until it abuts against the guiding rotating plate 816. Since there is no locking for the guiding plate, it rotates counterclockwise. Then the mounting seat 88 disengages from the guiding rotating plate 816, and the guiding rotating plate 816 returns to its original position. Until the mounting seat 88 moves to the maximum stroke, the optical fiber connector 12 is inserted into the insertion port 10. Then, after the detection is completed, it enters the second stroke of the sliding block 21. The mounting seat 88 moves horizontally in the direction of the guiding rotating plate 816 until it pushes the guiding rotating plate 816. After the guiding rotating plate 816 rotates, the L-shaped plate 819 is inserted into the hole of the guiding groove 813 again. At this time, the guiding rotating plate 816 is fixed, and the height of the outward protrusion on it extends higher than the horizontal section of the guiding groove 813. At this time, driven by the sliding seat and the abutting plate 8, the mounting seat 88 moves in the reverse direction again. At this time, the mounting seat 88 abuts against the outward protrusion of the guiding rotating plate 816. The outward protrusion of the guiding rotating plate 816 guides the mounting seat 88 at this time, and guides the mounting seat 88 downward into the inclined section of the guiding 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 that of the optical fiber plug-in part 11. Then the mounting seat 88 disengages from the inclined section of the guiding groove 813. The mounting seat 88 undergoes a horizontal movement again. At this time, the optical fiber connector 12 is inserted into the optical fiber plug-in part 11 again. By setting the wire rotating plate, the mounting seat 88 can have two different movement states and switch between the two movement states to realize the automatic detection operation of the optical fiber connector 12; It should be noted that when the L-shaped plate 819 on the guiding rotating plate 816 moves close to the hole, the L-shaped plate 819 will first contact the surface of the guiding groove 813. The contact position here needs to be set as a smooth curved surface to prevent the problem that the second spring 817 on the L-shaped plate 819 cannot deform and cause the L-shaped plate 819 to be locked. Similarly, when the L-shaped plate 819 is inserted into the hole in the guiding groove 813, the gap between the guiding rotating plate 816 and the guiding groove 813 needs to be smaller than the width of the second telescopic rod 814 to prevent the second telescopic rod 814 from being inserted into the gap and causing jamming. And when the second telescopic rod 814 transitions from the guiding groove 813 to the position of the locked guiding rotating plate 816, the position where the telescopic end of the second telescopic rod 814 contacts also needs to be set as a smooth curved surface. Similarly, it is also to prevent the problem that the second telescopic rod 814 is jammed; Here, by setting an extension plate 818 on the guiding rotating plate 816, the distance between the guiding rotating plate 816 and the guiding groove 813 can be reduced to facilitate the passage of the second telescopic rod 814. And the transition amplitude when the guiding groove 813 transitions to the space between the guiding rotating plate 816 and the guiding groove 813 can also be reduced by the extension plate 818, further improving the passing performance; It should also be noted here that the connection position of the second telescopic rod 814 on the mounting seat 88 is set at a position away from the L-shaped plate 819 to prevent the problem that the mounting seat 88 gets stuck with the guiding rotating plate 816 due to the mounting seat 88 abutting against the end of the L-shaped plate 819 first; 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 automatic surface crack detection system for the optical fiber connector further includes an arc-shaped seat two 91 slidably arranged on the hollow shell 6. A top plate 9 is arranged on the arc-shaped seat two 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. Moreover, the arc-shaped outer surfaces of the arc-shaped seat one 812 and the arc-shaped seat two 91 have the same curvature. 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 this time, the abutting plate 8 is separated from the groove 810, and the abutting plate 8 is contact-limited. When the abutting plate 8 moves in the reverse direction, it pushes the arc-shaped seat two 91, causing the arc-shaped seat to move upward. Thus, the top plate 9 pushes the clamping plate 85 upward, and the clamping plate 85 moves upward. A first spring 83 is arranged between the two clamping plates 85. When the two clamping plates 85 move upward to make the ball 82 contact the inclined surface of the wedge-shaped plate, the first spring 83 resumes deformation, and the two connecting rods 81 separate from each other, so that the two clamping plates 85 separate from each other, releasing the clamping of the optical fiber connector 12. Moreover, the arc-shaped outer surfaces of the arc-shaped seat one 812 and the arc-shaped seat two 91 have the same curvature, and when being squeezed by the abutting plate 8, the rising and falling distances are the same; In summary, the following explanations are also required. When detecting the fiber optic connector 12, the entire fiber optic 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 at the same time, the slider 21 will also move back and forth twice. However, during this process, the conveyor belt 3 only needs to move one station. Therefore, a first telescopic rod 89 is also provided between the mounting seat 88 and the telescopic end of the third telescopic rod 4. In this way, when the mounting seat 88 rises, it will also pull the third telescopic rod 4 upward through the first telescopic rod 89, and the first telescopic rod 89 contracts. In this way, when the entire detection process reaches the point of pulling the fiber optic connector 12 out of the insertion port 10, due to the height of the third telescopic plate, the contact push plate 41 on the telescopic end of the third telescopic plate will not come into contact with the inclined plate 32 and the pressure receiving plate 33, which also makes the conveyor belt 3 not move. It is not until all four motion states are completed, that is, after one detection is completed, that the conveyor belt 3 will move one station again. This process is repeated, so that the automatic detection of the fiber optic connector 12 can be realized. And through the same driving motor 2, not only can the mounting seat 88 have two different motion states, so that the fiber optic 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 fiber optic connector 12 to intermittently feed the fiber optic connector 12. The degree of automation is high, and no manual operation is required, with excellent use effects.
