Description

Full-automatic optical fiber connector end face detection device and detection system

Technical Field

The utility model relates to the technical field of optical fiber production equipment, in particular to a device and a system for detecting the end face of an optical fiber connector.

Background

The basic structure of an optical fiber connector, also called an optical fiber jumper, comprises an optical fiber line and a ceramic ferrule connected at the end part of the optical fiber line. The optical fiber line is a wire material before the optical fiber connector is not connected with a joint (a ceramic ferrule), and comprises an optical fiber and a protective layer for coating the optical fiber. In the production process, the coating layer with a fixed length at the end of the optical fiber is usually stripped, and then the core wire part stripped of the coating layer is inserted into the plug which is glued to form the fiber penetrating operation.

In order to improve the efficiency of fiber penetrating operation, automatic operation needs to be realized, correspondingly, plugs used in batches need to be fixed on the plug fixing strip, before fiber penetrating, glue dispensing operation is carried out on the plugs on the plug fixing strip, and batch fiber penetrating operation is completed on the plug fixing strip after glue dispensing at batch automatic fiber penetrating equipment. After the batch fiber threading operation is completed, the end face of the endmost end of the optical fiber extending out of the plug needs to be subjected to processes such as grinding, cleaning, drying, wiping, detection and the like. The detection processing mainly comprises the steps of scanning the end face of the optical fiber by using a camera on an end inspection instrument, and then identifying and judging whether the flatness, the cleanliness and the like of the end face meet requirements by the end inspection instrument.

The technical scheme of end face detection in the prior art includes that an end part of an optical fiber connector is manually inserted into an end face detection instrument by a worker, then the end face detection instrument identifies and judges the end face, and finally the worker sorts qualified products and unqualified products according to the result given by the instrument. The detection treatment efficiency is low, the labor intensity is high, and the labor cost is high.

In the prior art, there is also a technical scheme for end face detection, such as the chinese patent application with publication No. CN110375647A entitled "full-automatic fiber connector end face detection apparatus", which works by directly conveying an optical fiber fixing and clamping board for carrying optical fiber connectors with batch fibers threaded to a position where a supporting block is tightly attached to the lower surface of a fixing strip through a conveying device, then fixing a pressing plate tightly attached to the upper surface of the fixing strip from above the clamping board, and then collecting images of the fiber connector ends arranged in the fixing strip one by using a moving camera. However, the inventor finds that, in the process of completing the utility model of the present application, the detection result is not accurate enough due to the fact that the positioning effect of the fixing strip is not accurate enough, so that it is difficult for the camera for collecting the image to be aligned with the end face of the optical fiber connector accurately.

Accordingly, there is a need in the art for a fiber optic connector end face inspection device, system, and method to enable accurate inspection of batches of fiber optic connector end faces.

As shown in fig. 1 to 3, the optical fiber connector end surface inspection system 100 includes an optical fiber connector end surface inspection device 10, a rack 1, a carrier 2, and a transport driving device 21. As shown in fig. 3, a carrier 2 is slidably mounted on the frame 1, the carrier 2 is used for carrying batch optical fiber connectors 7 which are polished and cleaned at end faces to an end face detection station, the optical fiber connectors 7 in fig. 3 are fixed on a clamping seat 3 in batch, a plurality of clamping positions corresponding to the ferrules of the optical fiber connectors 7 are arranged in the middle of the clamping seat 3, and a clamping structure for clamping the ferrules of each optical fiber connector 7 is arranged at the clamping positions. Fig. 3 shows a structure in which the carrier 2 has carried the optical fiber connector 7 to the end inspection station where the end face of the optical fiber connector 7 can be inspected, and the clamping seat 3 is positioned, the bottom end of the carrier 2 is fixedly provided with the connector clamping seat 3, and the connector clamping seat 3 is preferably arranged in a long strip shape. The connector clamping seat 3 is provided with a plurality of clamping positions corresponding to the ferrules of the optical fiber connectors 7 in the middle, and the clamping positions are provided with clamping structures for clamping the ferrules of the optical fiber connectors 7. A conveying device 21 is disposed between the carrier 2 and the frame 1, and with continued reference to fig. 3, the conveying device 21 is used for conveying the carrier 2 to the end face detection station, and may be capable of conveying the carrier in a translational manner at the same height, the conveying device 21 may specifically include two conveying belt wheels 22 rotatably mounted on the frame 1, a double-sided toothed belt 23 is disposed between the two conveying belt wheels 22, a conveying toothed plate 24 constantly meshed with the double-sided toothed belt 23 is disposed on the carrier 2, and one conveying belt wheel 22 is connected to a conveying driving motor 25, but not limited thereto. As shown in fig. 3, the sliding mounting of the carrier 2 and the frame 1 is implemented by a sliding groove and sliding block structure, the frame 1 includes a sliding groove, and the conveying device 21 includes a sliding block, but not limited thereto, and may also be implemented by a guide rod and guide sleeve structure, for example. The frame 1 may be an aluminum profile or a plate or an assembly, but not limited thereto.

With continued reference to fig. 1-3, the fiber optic connector end face inspection device 10 includes an end inspection bracket 4, a clip mount fixture 50, and an end inspection camera 48. The end inspection bracket 4 can move vertically, and the specific structure can include a lifting and feeding device 49 arranged between the end inspection bracket 4 and the machine frame 1. The end detection support 4 is installed in a sliding mode through four guide rod guide sleeve structures, guiding effect is provided for vertical movement, and the lifting and feeding device 49 can generally adopt lifting and feeding cylinders, such as air cylinders, electric cylinders, hydraulic cylinders and the like. However, it is not limited to this, for example, the lifting and feeding device 49 may also adopt a spring telescopic structure in which a spring is directly connected to the end detecting bracket 4, or a lifting device in which a stepping motor precisely controls the lifting and lowering displacement, etc., and a slide rail-slide block structure may also be adopted to provide a guiding function for the vertical direction, even a guiding member is omitted, and the lifting and feeding device 49 is directly adopted to realize the vertical movement of the end detecting bracket 4.

The clamping base fixing device 50 may include clamping base platforms 5 corresponding to both ends of the clamping base 3, respectively, wherein one clamping base platform 5 is fixedly provided with a clamping block 51 serving as a fixing member, the other clamping base platform 5 is transversely slidably provided with a clamping block 52 serving as a moving member, and the clamping block 52 is connected with a clamping force application device 53. After the end inspection support 4 is driven to rise, the two clamping base platforms 5 firstly contact with the two ends of the clamping base 3 to form support, then the clamping force application device 53 pushes the clamping block 52, and the clamping block 52 can push the clamping base 3 to lean against the clamping block 51 to form clamping fixation. Because the carrier 2 is driven by the double-sided toothed belt 23 to slide, the double-sided toothed belt 23 has certain elasticity and the like, so that the clamping seat 3 can horizontally move in a small distance, the clamping block 52 can easily push the clamping seat 3 in a small distance to form clamping with the clamping block 51, and the gap between the initial position of the clamping block 51 and the clamping seat 3 is small. The clamping block 51 provided as a fixing member has an advantage of serving as a positioning of the clamping base 3 so that the optical fiber connector 7 on each clamping base 3 can be detected at a fixed designated position after the clamping base is clamped and fixed. The urging device 53 may be a commonly used air cylinder, electric cylinder, or hydraulic cylinder.

As described above, in actual operation, the conveying device 21 drives the carrier 2 to slide, so that the clamping base 3 is suspended and stopped after being positioned at the end inspection station, and then the end inspection support 4 is vertically moved and lifted from bottom to top by the lifting and feeding device 49 until the lower end face of the clamping base 3 is abutted and fixed, so that the clamping base 3 is vertically positioned. The beneficial effect is that the positioning of the clamping seat 3 can be accurate. The principle lies in that, compared with the vertical positioning that the lower surface of the fixing strip is directly attached to the supporting block in the patent document with the publication number of CN110375647A introduced in the background art, the vertical positioning scheme of the embodiment can avoid the deviation in the horizontal or longitudinal position caused by the interference and collision between the lower surface of the fixing strip and the supporting block due to the processing error of each component and the shake of the transmission device in the height direction in the translation process, so that the positioning of the clamping seat 3 is accurate, and the end face of the end-checking camera 48 is accurately aligned with the end face of the optical fiber connector 7.

During the operation of the detection device 10, the lifting and feeding device 49 drives the detection support 4 to lift until the lower end surface of the clamping base 3 is abutted and positioned (in the embodiment shown in the figure, the two carrying platforms 5 are in contact with the lower end surface of the clamping base 3 to form supporting and abutting positioning), the clamping block 52 as a moving part is pushed by the force application device 53, and the clamping base 3 is pushed to lean against the clamping block 51 as a fixed part to form clamping and fixing. The arrangement of the clamping seat fixing device 50 can enable the clamping seat 3 to be transversely clamped on the basis that the end detection station is vertically abutted and fixed, so that the clamping seat 3 is accurately aligned when the end face detection is carried out, the obtained image of the end face of the optical fiber connector is clear, and the detection result is accurate. With continued reference to fig. 1 to 3, the connection and engagement structure between the clamping blocks 51 and 52 and the clamping seat 3 may be a V-shaped clamping block and groove structure, the clamping seat 3 has V-shaped clamping groove portions 31 at two lateral ends, and the clamping blocks 51 and 52 have V-shaped clamping block portions 54 capable of being clamped into the V-shaped clamping groove portions 31 at corresponding ends, respectively, but not limited thereto, for example, the clamping blocks 51 and 52 may have V-shaped clamping groove portions 31, and the clamping seat 3 has V-shaped clamping block portions 54, which has the beneficial effects that the V-shaped clamping block and groove structure can improve the stability of the clamped connector clamping seat 3 on one hand, and can limit the width direction, that is, the longitudinal direction of the connector clamping seat 3 on the other hand, so as to further improve the position accuracy of the optical fiber connector 7 when being detected. With continued reference to fig. 1 to 3, the end-inspecting camera 48 may be a single mobile end-inspecting camera, which is moved in the extending direction of the clip housing 3, i.e., in the lateral direction in the drawing, and takes images of the end faces of the optical fiber connectors 7 of the clip housing 3 one by one, and outputs the images for inspection. It should be understood that the specific structure of the end inspection camera is not limited to the embodiment in the drawings, for example, the end inspection camera may be a plurality of mobile type or a plurality of fixed type, and the number of the fixed type end inspection cameras is the same as the number of the optical fiber connectors that can be clamped by the clamping seat 3. The detection may be performed by further connecting the end inspection camera 48 with a controller, and the controller may process and analyze the image transmitted by the end inspection camera 48, compare the image with a set value, and finally determine whether the end face of the optical fiber connector 7 corresponding to the image is qualified. When the unqualified product is detected, the controller stores and records the unqualified product for subsequent reference and processing. Conventionally, the controller includes a central processing unit, an image processing unit, a comparison unit, a data transmission unit, and the like. It can be understood that besides the storage record of the unqualified products, other entity marking modes can be adopted to sort the unqualified products differently, for example, a clamp is arranged on the end inspection support 4, and the unqualified products are pulled out upwards by a certain length according to the signal output of the controller. With continued reference to fig. 1 to 3, for the mobile end inspection camera 48, the component driving the mobile end inspection camera 48 to move may be a first moving assembly 400 included in the inspection apparatus 10, which includes a first driving component, a longitudinal moving component and a vertical moving component, the first driving component is used for driving the end inspection camera 48 to move along the working direction (i.e. the transverse direction in the drawing) to reach the working position, i.e. the position where the end face of each optical fiber connector 7 is located, and the longitudinal moving component and the vertical moving component are used for finely adjusting the longitudinal position and the vertical position of the end inspection camera at the working position. It can be understood that the arrangement of the longitudinal moving member and the vertical moving member is only a scheme for adjusting the positioning of the end inspection camera 48 and the clamping base 3 with slight deviation, and under ideal conditions, for example, the displacement precision of the first driving member is sufficient, the processing is sufficiently accurate, and the like, because of the adoption of the end inspection bracket 4 and the clamping base fixing device 50, the end inspection camera 48 and the optical fiber connector 7 can be aligned sufficiently accurately, and at this time, the longitudinal moving member and the vertical moving member are not needed. As shown in fig. 1 to 3, the first moving assembly 400 may be specifically configured such that the first driving member includes an end inspection carriage 41, an end inspection carriage 43, and a translation feeding device 42, the end inspection carriage 43 is slidably mounted on the end inspection bracket 4, and the translation feeding device 42 is disposed between the end inspection carriage 43 and the end inspection bracket 4. The translation advancement device 42 may be generally a pneumatic cylinder, as shown, or an electro-pneumatic cylinder. The translation feeding device 42 is used for driving the end detection carriage 41 to intermittently slide, and each time the sliding stops, the end detection camera 48 is positioned below one of the optical fiber connectors 7, and the end detection camera 48 can take pictures and transmit the pictures. Vertical moving member is including being located the vertical fine setting slip table 44 that moves that sets up between middle seat 45 and end detection slide 43, is provided with mount pad 47 on the middle seat 45, and vertical moving member is including being located the vertical fine setting slip table 46 that moves that sets up between mount pad 47 and middle seat 45, and camera 48 is examined to the installation end on the mount pad 47. Through position adjustment, the end-checking camera 48 can conveniently shoot clear images. In this embodiment, the longitudinal fine adjustment sliding table 44 and the vertical fine adjustment sliding table 46 both adopt the existing high-precision cross roller type sliding tables, and the relative positions of the two structures connected with the sliding tables can be finely adjusted by the

micrometer

440 or 450 in a linear direction.

In summary, in the operation of the optical fiber connector end face inspection system 100 described in the above embodiment, the conveying device 21 drives the carrier 2 to slide, so that the gripper seat 3 is stopped after being at the end inspection station. The lift-feed device 49 then drives the end inspection stand 4 to lift until the gripper seat carrier 5 is supported to the lower end surfaces of the two lateral ends of the gripper seat 3. The urging device 53 drives the clamp block 52 to slide, and the clamp block 52 and the clamp block 51 finally fix and clamp the clamping base 3. The fixed arrangement of the clamping block 51 and the clamping of the V-shaped clamping blocks 54 of the clamping block 51 and the clamping block 52 can ensure that the clamping seat 3 can be quickly and accurately positioned in the transverse direction and the longitudinal direction. The end inspection camera 48 can adjust the position in advance by using the longitudinally-moving fine adjustment sliding table 44 and the vertically-moving fine adjustment sliding table 46 according to the position capable of being quickly and accurately positioned, so that the end inspection camera 48 can directly reach the optical fiber connector 7 at the head end to perform ideal shooting after the end inspection support 4 is lifted. The end inspection camera 48 photographs the end face of the optical fiber connector 7 at the head end, and transmits the image to the controller, and the controller processes and analyzes the image, compares the image with a set value, and then obtains a conclusion whether the image is qualified or not. If not, recording and storing the corresponding unqualified product. The translation feeding device 42 drives the whole end detection carriage 41 to perform a displacement once again, the displacement is equal to the distance between two adjacent optical fiber connectors 7 on the clamping seat 3, and then the end detection camera 48 performs the next shooting. And the rest is done until the end of the last optical fiber connector 7 is detected. The clamping biasing device 53 releases the clamping fixation of the clamping base 3, the end inspection bracket 4 is driven to descend to return to the initial position, and the end inspection carriage 41 returns to the initial position. The conveying device 21 drives the carrier 2 to slide away, and conveys the clamping seats 3 on the next carrier 2 to the end detection station, and continues to detect the end faces of the next batch of optical fiber connectors 7.

As can be seen from the above description and with reference to fig. 4, a method for inspecting end faces of optical fiber connectors in a batch of optical fiber connectors includes:

s1, moving the optical fiber connector to an end face detection station to be suspended;

for example, as described above, the conveying device 21 drives the carrier 2 to slide, so that the clamping base 3 is suspended and stopped after being positioned at the end inspection station;

s2, positioning the suspended optical fiber connector in the horizontal direction and the vertical direction;

for example, as described above, the end test support 4 is first lifted by the lifting and feeding device 49 from bottom to top until the lower end surface of the clamping seat 3 is abutted and fixed, so that the suspended optical fiber connector is first positioned vertically, and then the clamping seat 3 is clamped by the two clamping blocks 51 and 52 in the transverse direction, so that the optical fiber connector is clamped and positioned in the transverse direction.

S3, detecting the end face of the optical fiber connector;

for example, as described above, after the positioning is completed, the end-checking camera 48 can move in the transverse direction to take images of the end faces of the optical fiber connectors 7 one by one, and output the images to the controller for comparison.
