Description

Technical Field

[0001] The invention relates to the technical field of optical fiber production, and in particular to an optical fiber connector end face detection device. Background Art

[0002] Fiber optic connectors are crucial components in fiber optic communication systems and are used to achieve efficient connections between optical fibers. The quality of the fiber optic connector end face directly affects the transmission efficiency of optical signals and the stability of the communication system. If there are stains, scratches, dust or other defects on the end face of the fiber optic connector, it will increase the loss of the optical signal and even cause communication interruption. Therefore, the end face detection of the fiber optic connector is a key step to ensure the reliable operation of the fiber optic communication system. The end face of the fiber optic connector is usually inspected using a fiber optic microscope or a fiber optic end face detector, which can magnify the end face image and help the operator to intuitively observe the cleanliness and integrity of the end face. When stains are detected on the end face, a special cleaning tool is required to wipe it. Traditional manual inspection and wiping are inefficient and costly, and manual operations are easily affected by subjective factors, resulting in inconsistent cleaning effects. Therefore, the development of an efficient and automated fiber optic connector end face detection device has become an important direction for improving the production efficiency and reliability of fiber optic communication systems.

The second end of the support shaft 157 is used to support the first combining plate 151 to prevent the first combining plate 151 from radially moving relative to the third gear 15.

[0037] The adsorption block 22 is provided with a first notch 221, and the first notch 221 is used to accommodate the rope body 19 or the guide wheel 191 to pass through to avoid interference. Fig.14 , a corresponding second notch is also provided on the first combining plate 151, and the second notch is used to accommodate the rope body 19 or the guide wheel 191 passing through. In this embodiment, the first conveyor belt 2 can make regular circular rotation with the third gear 15, that is, the third gear 15 rotates an integer number of circles under the drive of the first conveyor belt 2. When the first conveyor belt 2 stops conveying, the third gear 15 stops rotating. At this time, the second notch of the first combining plate 151 corresponds to the position of the rope body 19 or the guide wheel 191 to avoid interference. At the same time, the second end of the support shaft 157 and the guide hole of the first combining plate 151 correspond to the guide slide 21, so that the first combining plate 151 can slide between the support shaft 157 and the guide slide 21.

[0038] For further reference, Figure 8The winding sleeve 18 is sleeved on the outside of the second wheel body 17. The edge of the second wheel body 17 is provided with a plurality of evenly distributed clamping blocks 171 and a groove that can accommodate the clamping blocks 171. The clamping blocks 171 are connected to the bottom of the groove of the second wheel body 17 through the third elastic member 172. One side of the clamping block 171 is an inclined surface, and the other side of the clamping block 171 is a plane perpendicular to the tangent line of the second wheel body 17. The inner edge of the winding sleeve 18 is provided with an accommodating groove for accommodating the clamping block 171. When the winding sleeve 18 rotates in the first direction, the rope body 19 is wound, the inclined surface of the block 171 is the force-bearing surface, the block 171 is retracted into the groove of the second wheel body 17, and the second wheel body 17 does not rotate; when the third gear 15 stops rotating, the fifth elastic body 211 pulls the slider 20 back, and the rope body 19 can pull the winding sleeve 18 to rotate in the second direction. The second direction is opposite to the rotation direction of the first direction, forming the action of unwinding the rope body 19. At this time, the plane of the block 171 is the force-bearing surface, and the winding sleeve 18 can rotate with the second wheel body 17 in the second direction. Because the adsorption block 22 adsorbs the first binding plate 151, the binding rod 153 and the binding hole 161 are in a separated state, that is, the third gear 15 is not combined with the winding sleeve 18, and the third gear 15 does not rotate. During the return process of the slider 20, the adsorption block 22 can continue to move with the first binding plate 151 to keep the binding rod 153 and the binding hole 161 in a state of continuous separation.

[0039] Furthermore, a limit rod 213 is fixedly provided on the guide slide 21, one end of the limit rod 213 is fixedly connected to the outside of the guide slide 21, and the other end of the limit rod 213 extends to one side of the end face of the adsorption block 22, and the end of the limit rod 213 is closer to the third gear 15 relative to the end face of the adsorption block 22. When the first coupling plate 151 moves following the adsorption block 22, the sixth elastic body 156 keeps pulling the first coupling plate 151. Fig.11 , until the adsorption block 22 is located at the second extreme position, the limiting rod 213 limits the movement of the first combining plate 151, the first combining plate 151 is separated from the adsorption block 22, and the sixth elastic body 156 can pull the first combining plate 151 back to its original position, so that the first combining plate 151 and the second combining plate 152 return to their initial positions. At this time, the third combining plate 16 also returns to its original position, and the combining rod 153 on the second combining plate 152 corresponds to the combining hole 161 of the third combining plate 16. The combining rod 153 on the second combining plate 152 can be inserted into the combining hole 161 of the third combining plate 16 again, so as to realize the re-combination between the third gear 15 and the winding sleeve 18.

[0040] The second wheel body 17 is fixedly connected to the fourth gear 24 through the first connecting shaft 23, the first connecting shaft 23 is rotatably connected to the base 1, the fourth gear 24 and the fifth gear 26 are bevel gears, the fourth gear 24 is meshed with the fifth gear 26, the fifth gear 26 is coaxially connected to the third wheel body 25 through the second connecting shaft 261, and the second connecting shaft 261 is rotatably connected to the base 1. The second wheel body 17 can rotate with the third wheel body 25 through the first connecting shaft 23, the fourth gear 24, the fifth gear 26 and the second connecting shaft 261.

[0041] refer to Figure 5 , extension rods 35 are respectively arranged on both sides of the movable block 32 of the material table 3, and rollers 36 are arranged at the bottom of the extension rods 35, and the rollers 36 are used to contact with the third wheel body 25. Figure 7 The outer edge of the third wheel body 25 at least includes a first contact segment 251, a second contact segment 252 and a non-contact segment 253. The radius of the non-contact segment 253 is smaller than the minimum distance between the axis of the third wheel body 25 and the roller 36. The radius of the first contact segment 251 and the second contact segment 252 is larger than the minimum distance between the axis of the third wheel body 25 and the roller 36. The second contact segment 252 is an arc segment with a consistent radius, and the first contact segment 251 is an arc segment with an inconsistent radius.

[0042] The third wheel body 25 is driven to rotate by the pusher structure, and the first contact section 251, the second contact section 252 and the non-contact section 253 correspond to the roller 36 in sequence. When the roller 36 contacts the first contact section 251 of the third wheel body 25, the rotation of the third wheel body 25 is used to move the movable seat 9 towards the direction close to the detection member 4; until the end face of the optical fiber connector on the movable seat 9 is inserted into the detection socket 41 of the detection member 4, refer to Fig.10 , the roller 36 contacts the second contact section 252 of the third wheel body 25, and the rotation of the third wheel body 25 no longer moves the movable seat 9 to keep the end of the optical fiber connector in the detection socket 41 of the detection member 4, giving a certain detection time; the third wheel body 25 continues to rotate, and the third wheel body 25 no longer contacts the roller 36, reference Figure 7 , that is, the non-contact section 253 of the roller 36 corresponding to the third wheel body 25 , under the action of the first elastic member 34 , the movable block 32 and the movable seat 9 return to their original positions, and the end of the optical fiber connector is pulled out from the detection socket 41 of the detection member 4 .

[0043] The above-mentioned detection part 4 is an optical fiber end face detector with an automatic focusing function, which can automatically adjust the distance between the lens and the end face of the optical fiber connector to obtain a clear image, thereby accurately evaluating the smoothness, cleanliness and geometry of the optical fiber end face. When the end of the optical fiber connector is inserted into the detection socket 41 of the detection part 4, the optical fiber end face detector can automatically detect the end face of the optical fiber connector. When the end face of the optical fiber connector meets the preset product standards, the optical fiber connector is judged to be a qualified optical fiber connector; when the end face of the optical fiber connector does not meet the preset product standards, such as the end face has scratches, the end face is not smooth enough, the end face shape is not compliant, etc., these defects need to be reworked and repaired, then the optical fiber connector is judged to be an unqualified optical fiber connector; when there is dust or stains on the end face of the optical fiber connector, clean it again.

The outside of the feed rotating member 6 is provided with a second limiting plate 61, and the second limiting plate 61 is annular. The second limiting plate 61 is used to cover the opening of the first material slot 63 to prevent the optical fiber connector from falling out of the first material slot 63 during the rotation of the feed rotating member 6. The upper part of the second limiting plate 61 is provided with a first feed port for feeding the optical fiber connector, and the lower part of the second limiting plate 61 is provided with a first discharge port for discharging the optical fiber connector. The first discharge port faces the first conveyor belt 2. When the material platform 3 passes through the first discharge port, the optical fiber connector can enter the material platform 3 of the first conveyor belt 2 from the first discharge port. The clamping plate 91 on the movable seat 9 can clamp the optical fiber head 8 of the optical fiber connector, and at the same time, the optical fiber body 81 of the optical fiber connector enters the placement space 97 of the movable seat 9.

[0045] The feed rotating member 6 is transmitted through the power transmission member 7, referring to Fig.15 and Fig.16The power transmission member 7 includes a first gear 71, a second gear 72 and a gear ring 73. The first gear 71 and the gear ring 73 are coaxially arranged. The second gear 72 is located between the first gear 71 and the gear ring 73 and meshes with the first gear 71 and the gear ring 73 respectively. The wheel shaft 721 of the second gear 72 is rotatably connected to the wheel frame 74 respectively. The outer portion of the wheel frame 74 is sleeved with a seventh gear 741. The rotating shaft of the feed rotating member 6 is fixedly connected with a sixth gear 62. The sixth gear 62 and the seventh gear 741 are connected through a synchronous belt 14. The synchronous belt 14 is a second toothed belt. The first gear 71 is fixedly sleeved on the transmission shaft 202 of the transmission wheel 201 on the first conveyor belt 2. The transmission wheel 201 can rotate with the first gear 71 through the transmission shaft 202, forming the rotation and movement of the second gear 72. The movement of the second gear 72 can form the rotation of the wheel frame 74, and then form the rotation feeding of the feeding rotating member 6, maintaining a fixed transmission speed ratio between the feeding rotating member 6 and the first conveyor belt 2, thereby ensuring the accurate feeding of the optical fiber connector.

[0046] Furthermore, the base 1 is provided with a first brake block 121, a first functional cylinder 12, a second brake block 131 and a second functional cylinder 13, and the first functional cylinder 12 and the second functional cylinder 13 are fixedly connected to the base 1.

[0047] When the feeding rotating member 6 feeds, the gear ring 73 is braked and limited by the first brake block 121. When the end face of the optical fiber connector is detected and there is stain on its surface, the optical fiber connector will not be discharged, but will be transported by the first conveyor belt 2 and returned to the feeding position again, and will be cleaned again by the end face cleaning member 5, and will be tested again by the testing member 4. When the optical fiber connector returns to the feeding position again, the feeding rotating member 6 will not feed, and the wheel frame 74 will be braked and limited by the second brake block 131, stopping the rotation of the feeding rotating member 6. At this time, the first brake block 121 releases the brake limit on the gear ring 73, and the gear ring 73 can rotate freely.

[0048] refer to Figure 2 The base 1 of the optical fiber connector end face detection device is provided with an industrial camera 11, which is located behind the second discharging structure 29 and is used to detect whether there is an optical fiber connector left on the material platform 3. If the industrial camera 11 detects that there is an optical fiber connector on the material platform 3, the first function cylinder 12 and the second function cylinder 13 are controlled to work respectively, the first brake block 121 releases the brake limit on the gear ring 73, and the second brake block 131 brakes the wheel frame 74. If the industrial camera 11 detects that there is no optical fiber connector on the material platform 3, the first brake block 121 is kept in the brake limit position on the gear ring 73 and the wheel frame 74 is kept in the free rotation state.

[0049] refer to Figure 1 and Figure 2 In this embodiment, a first limit plate 10 is also provided on the base 1 of the optical fiber connector end face detection device. The first limit plate 10 covers the conveying surface and the lower conveying surface of the two ends of the first conveyor belt 2 to prevent the optical fiber line 81 of the optical fiber connector from moving out of the placement space 97 of the movable seat 9. The first discharge structure and the second discharge structure 29 are respectively located below the first limit plate 10. The first discharge structure is used for discharging qualified optical fiber connectors, and the second discharge structure 29 is used for discharging unqualified optical fiber connectors. The first limit plate 10 is provided with discharge channels for discharging optical fiber connectors at the positions of the first discharge structure and the second discharge structure 29.

[0050] refer to Figure 2 The above-mentioned first discharging structure includes a receiving part 27 and a discharging plate 28. The discharging plate 28 is slidably connected to the bottom of the first limiting plate 10. One end of the discharging plate 28 is connected to the base 1 through a fourth functional cylinder 281.

[0051] Furthermore, the receiving member 27 includes a discharging rotating body 271, a second material trough 272 and a third limiting plate 273. The discharging rotating body 271 is rotatably connected to the base 1, and the base 1 is provided with a second motor for driving the discharging rotating body 271 to rotate. Two second material troughs 272 are provided on the edge of the discharging rotating body 271, and the two second material troughs 272 are symmetrically arranged on the discharging rotating body 271. The second material trough 272 is used to place the optical fiber connector. A third limiting plate 273 is provided on the outside of the discharging rotating body 271. The third limiting plate 273 is annular and is used to cover the opening of the second material trough 272 to prevent the optical fiber connector from falling out of the second material trough 272 during the rotation of the discharging rotating body 271. A second feed port is provided on the upper part of the third limiting plate 273, and the second feed port faces the discharge channel of the first limiting plate 10. When the optical fiber connector is discharged, it enters the second material trough 272 from the discharge channel of the first limiting plate 10 and the second feed port of the third limiting plate 273. A second discharge port is provided at the bottom of the third limiting plate 273, and a second conveyor belt 101 is provided below the second discharge port.

[0052] In this embodiment, the second discharge structure 29 has the same structure as the first discharge structure described above, and a third conveyor belt 102 is provided below the second discharge structure 29. The third conveyor belt 102 is used to convey unqualified optical fiber connectors to a second designated discharge position for rework.

[0053] The base 1 of the optical fiber connector end face detection device is provided with a sixth motor (not shown) for driving the second conveyor belt 101 for transmission and a seventh motor (not shown) for driving the third conveyor belt 102 for transmission.

[0054] The working process of the optical fiber connector end face detection device in this embodiment is as follows: Step 1: Place the optical fiber connector into the first feed port of the feed rotating member 6. Through the rotation of the feed rotating member 6, the optical fiber connector can be fed into the feed rotating member 6 from the first discharge port onto the material table 3 of the first conveyor belt 2. The clamping plate 91 on the movable seat 9 can clamp the optical fiber head 8 of the optical fiber connector, and at the same time, the optical fiber body 81 of the optical fiber connector enters the placement space 97 of the movable seat 9. Step 2: The first conveyor belt 2 moves with the optical fiber connector on the material table 3. When the contact block 93 of the movable seat 9 contacts the limiting seat 30, the first inclined surface of the limiting seat 30 contacts the second inclined surface of the contact block 93. The contact block 93 moves relative to the limiting seat 30, so that the movable seat 9 and the contact block 93 move toward the end face cleaning member 5. The end face of the optical fiber connector on the movable seat 9 contacts the end face cleaning member 5. At the same time, the first conveyor belt 2 continues to move with the optical fiber connector. The end face cleaning member 5 wipes the end face of the optical fiber connector to remove stains on the end face of the optical fiber connector. Step 3: After the material table 3 passes through the limiting seat 30, the end face of the optical fiber connector is cleaned, and the movable seat 9 and the contact block 93 are returned to their original positions; Step 4: Before the material platform 3 passes through the detection member 4, the toothed belt portion of the first conveyor belt 2 can drive the third gear 15 to rotate in the first direction during the conveying process, referring to Figure 7 At this time, the pusher structure is in the first state. Under the action of the fourth elastic member 154, the combining rod 153 on the second combining plate 152 is inserted into the combining hole 161 of the third combining plate 16, and the third gear 15 is combined with the winding sleeve 18. The third gear 15 and the winding sleeve 18 rotate synchronously to form a winding action of the rope body 19. The rope body 19 pulls the slider 20 and the adsorption block 22 to move toward the direction close to the third gear 15; when the adsorption block 22 is at the first limit position, refer to Fig. 9 At this time, the pusher structure is in the second state, the adsorption block 22 adsorbs the first combining plate 151, the first combining plate 151 moves from the second end of the support shaft 157 to the guide slide 21, and the second combining plate 152 moves away from the third combining plate 16, so that the combining rod 153 is separated from the combining hole 161. At this time, the second wheel body 17 does not rotate, that is, the fourth gear 24, the fifth gear 26 and the third wheel body 25 do not rotate. At this time, the non-contact section 253 of the third wheel body 25 is in contact with the roller 36; When the material table 3 comes to the position corresponding to the detection member 4, the position of the optical fiber connector corresponds to the detection socket 41 of the detection member 4, and the first conveyor belt 2 stops conveying. At this time, the third gear 15 stops rotating, and the fifth elastic body 211 pulls the slider 20 back to its original position. The rope body 19 can pull the winding sleeve 18 to rotate in the second direction. Since the combining rod 153 and the combining hole 161 are in a separated state at this time, that is, the third gear 15 is not combined with the winding sleeve 18, the third gear 15 does not rotate; the second direction is opposite to the first direction of rotation, and the winding sleeve 18 can rotate with the second wheel body 17 in the second direction. The second wheel body 17 rotates one circle with the third wheel body 25 through the first connecting shaft 23, the fourth gear 24 and the fifth gear 26; During the rotation of the third wheel body 25, the first contact section 251, the second contact section 252 and the non-contact section 253 of the third wheel body 25 contact the roller 36 on the material table 3 in sequence. When the first contact section 251 of the third wheel body 25 contacts the roller 36, the third wheel body 25 moves the movable seat 9 toward the detection member 4 until the end of the optical fiber connector is inserted into the detection socket 41 of the detection member 4. Fig.10 At this time, the pushing structure is in the third state, the second contact section 252 of the third wheel body 25 contacts the roller 36, and the rotation of the third wheel body 25 no longer drives the movable seat 9 to move, which is used to keep the end of the optical fiber connector in the detection socket 41 of the detection member 4. After a certain detection time, the third wheel body 25 continues to rotate, and the third wheel body 25 no longer contacts the roller 36, that is, it enters the non-contact section 253 of the third wheel body 25. Figure 7 , under the action of the first elastic member 34, the movable block 32 and the movable seat 9 return to their original positions; After the third wheel 25 rotates one circle, when the adsorption block 22 returns to the second limit position, Fig.11 At this time, the pusher structure is in the fourth state, the limiting rod 213 limits the movement of the first combining plate 151, the first combining plate 151 is separated from the adsorption block 22, the sixth elastic body 156 pulls the first combining plate 151 back to the initial position, the second combining plate 152, the winding sleeve 18 and the third combining plate 16 are all returned to their positions, and the combining rod 153 on the second combining plate 152 can be inserted into the combining hole 161 of the third combining plate 16 again, so as to realize the re-combination between the third gear 15 and the winding sleeve 18; Step 5: After the material platform 3 is inspected by the inspection component 4, the inspection component 4 will determine whether the end face of the optical fiber connector is qualified or whether there is stain; When the end face of the optical fiber connector is qualified, when the material platform 3 passes through the first discharging structure, the first discharging channel corresponding to the first limiting plate 10 is opened, and the optical fiber connector enters the second material trough 272 from the first discharging channel and the second feeding port of the third limiting plate 273, and enters the second conveyor belt 101 from the second discharging port through the rotation of the discharging rotating body 271; When the optical fiber connector end face detection fails, when the material platform 3 passes through the second discharging structure 29, the second discharging channel corresponding to the first limit plate 10 is opened, and the optical fiber connector passes through the second discharging structure 29 from the first discharging channel and enters the third conveyor belt 102; When there are stains on the end face of the optical fiber connector, the optical fiber connector will not be discharged. After the material platform 3 passes through the second discharge structure 29, the industrial camera 11 detects whether there is an optical fiber connector left on the material platform 3. If there is an optical fiber connector on the material platform 3, the first function cylinder 12 and the second function cylinder 13 are controlled to work respectively, the first brake block 121 releases the brake limit on the gear ring 73, and the second brake block 131 brakes and limits the wheel frame 74, the wheel frame 74 does not rotate, the rotation of the feeding rotating member 6 stops, the feeding rotating member 6 does not feed, and the first conveyor belt 2 brings the optical fiber connector to the feeding position, and performs secondary cleaning of the end face cleaning member 5 and secondary inspection of the inspection member 4; if there is no optical fiber connector on the material platform 3, the first brake block 121 is kept in the brake limit on the gear ring 73 and the wheel frame 74 is in a free rotation state.
