[0022] It should be added that the linear drive is an electric slide.

Guide posts 12 are fixed on both sides of the upper connector, and the guide posts 12 match the guide sleeves 16; It should be added that the combination of the upper connector and the lower connector is a connector set.

[0029] The tooling test system includes a data acquisition module and an adjustment module. The data acquisition module includes an image receiving submodule and a logic judgment submodule. The image receiving submodule is electrically connected to the camera 29. The adjustment module includes a marking submodule, a telescopic control submodule and an alarm submodule. The telescopic control submodule is electrically connected to the first cylinder 13, the third cylinder 5, the second cylinder 9 and the linear drive. The tooling test system includes the following specific operating steps: Step 1: Fix the lower connector to the inside of the fixing shell 1 21 and the upper connector to the inside of the fixing shell 2 22; Step 2: Start the lifting assembly to control the lifting plate 2 and the lower mounting shell 8 to form a test cavity, and then control the upper connector to move downward through the linear drive to dock the upper connector with the lower connector; Specifically, the third cylinder 5 is started to extend and drive the lifting plate 2 to move downward so that cavity 19 and cavity 2 20 form a test cavity, and then the telescopic control sub-module controls the straight line to drive the start, thereby driving the two groups of second cylinders 9 to move downward, so that the upper connector moves downward and the guide column 12 is inserted into the guide sleeve 16, which plays a guiding and positioning role, so that the optical fiber 17 is inserted into the jack 18 of the lower connector, and the upper connector and the lower connector are connected.

[0030] Step 3: After the upper connector and the lower connector are connected, the camera 29 is used to photograph the joint of the upper connector and the lower connector to determine the matching condition of the upper connector and the lower connector, and different measures are taken according to the matching condition; Specifically, the camera 29 transmits the image of the docking point of the upper connector and the lower connector to the image receiving submodule. When it is recognized that the docking point of the upper connector and the lower connector is completely matched, it means that the upper connector and the lower connector are well matched. When it is recognized that the docking point of the upper connector and the lower connector is uneven, it means that the upper connector and the lower connector are poorly matched. When it is recognized that the docking point of the upper connector and the lower connector is flat (parallel to each other), but not completely docked, with a little distance left between them, it means that there is a jam between the upper connector and the lower connector, indicating that the matching degree is intermediate.

[0031] When the matching degree between the upper connector and the lower connector is intermediate, first clean the guide sleeve 16 and the socket 18 on the lower connector. Then, control the extension of the third cylinder 5 to increase the docking strength between the upper connector and the lower connector. Specifically, the first pump body 14 is started to pass the external wind source through the air duct 11, and then the gas is sprayed into the guide sleeve 16 and the socket 18 on the lower connector through the nozzle 28 to blow out the internal impurities. After the impurities are blown out, the linear drive is controlled to drive the upper connector to move downward, and the camera 29 is used again to identify the matching status of the upper connector and the lower connector docking. When the upper connector and the lower connector docking are completely matched at this time, it means that the impurities affect the matching of the upper connector and the lower connector. When the upper connector and the lower connector docking still maintain the status quo, it means that the diameter of the guide column 12 is slightly larger than the diameter of the guide sleeve 16 or the diameter of the optical fiber 17 is slightly larger than the diameter of the socket 18, which proves that the dimensions of the guide column 12 and the guide sleeve 16, and the optical fiber 17 and the socket 18 are deviated but are in a concentric state (such as Figure 6 As shown), the signal is transmitted to the alarm submodule to inform the staff to remove the upper connector; When the upper connector and the lower connector are poorly matched, it means that the guide pin 12 and the guide sleeve 16, the optical fiber 17 and the jack 18 are not in a concentric state (e.g. Figure 7 ), which proves that the connector set is defective and cannot be used normally.

[0032] Through the above steps, the matching degree between the upper connector and the lower connector is determined, and it is identified whether the guide pin 12 and the guide sleeve 16, and the optical fiber 17 and the jack 18 are in a concentric state, thereby ensuring the detection accuracy.

[0033] Step 4: When the upper and lower connectors are well matched, perform multiple plugging and unplugging to further determine the quality of the connector assembly. Step 4 includes the following specific steps: Step 4-a: When the upper and lower connectors are highly compatible, a signal is transmitted to the telescopic control submodule, which controls the linear drive to move up and down quickly, thereby driving the upper and lower connectors to be plugged and unplugged continuously. During the plugging and unplugging process, the docking status of the upper and lower connectors is further determined. Specifically, the number of plugging and unplugging times N is set in the logic judgment submodule, and step three is repeated during the plugging and unplugging process to detect the matching status of the upper connector and the lower connector in real time. When the number of plugging and unplugging times reaches N times and the connector and the lower connector are well matched, it indicates that the guide post 12 and the guide sleeve 16, the optical fiber 17 and the socket 18 are not affected by the friction between plugging and unplugging during plugging and unplugging; when the number of plugging and unplugging times N is not reached during the plugging and unplugging process and the matching degree of the upper connector and the lower connector becomes worse, it indicates that the guide post 12 and the guide sleeve 16, the optical fiber 17 and the socket 18 are deformed due to the heat generated by a large amount of friction during the rapid plugging and unplugging process, affecting the matching degree, and the operation of the linear drive is suspended at this time. After a period of time, the first pump body 14 is turned on at the same time to spray air onto the guide post 12 and the guide sleeve 16, the optical fiber 17 and the socket 18 to cool down and dissipate heat. After cooling and dissipating heat, the quick plug-in state is restored. During the quick plug-in process, the matching condition of the connector group is still judged. When the matching degree of the connector group is restored, subsequent work can be carried out. When the matching degree of the connector group still has problems, it indicates that the guide post 12 and the guide sleeve 16, the optical fiber 17 and the socket 18 on the connector group are easily affected by heat and deformed and difficult to recover. At this time, the signal is transmitted to the marking submodule to mark the connector as A.

[0034] When the upper connector is marked as A, the camera 29 continues to capture the status of the upper connector. If it is identified that the upper connector is asymmetrical on the left and right, it means that the pressure plates 10 on both sides of the upper connector are displaced during multiple quick plug-in and pull-out processes, resulting in an uneven docking position between the upper connector and the lower connector, thereby affecting the docking between the upper connector and the lower connector during quick plug-in and pull-out. Therefore, it is necessary to inform the staff again to reinstall and adjust the upper connector to improve detection efficiency.

[0035] Step 4-b: After the quick plug and unplug, further determine the quality of the connector assembly after the quick plug and unplug; Specifically, the linear drive is controlled to descend so that the upper connector and the lower connector are docked, and the second pressure plate 10 is no longer controlled to clamp the upper connector. At this time, the camera 29 takes a real-time picture of the appearance of the upper connector and transmits it to the image receiving submodule. Since the staff has set the normal appearance of the upper connector in the logic judgment submodule, the state of the upper connector received by the image receiving submodule is compared with the image set in the logic judgment submodule. If the two match, it means that the appearance of the upper connector has not been deformed. If they do not match the image set in the logic judgment submodule, it means that the upper connector has been subjected to excessive pressure from the second pressure plate 10 during the plugging and unplugging process, resulting in a large degree of external deformation. Furthermore, when the upper connector is marked as A, since the upper connector is displaced during the quick plug-in and unplugging process and the shape of the upper connector is deformed, it means that the upper connector is displaced due to deformation, thereby affecting the quick plug-in test, and the signal is transmitted to the alarm sub-module to inform the staff that there is a problem with the quality of the upper connector. When the upper connector is displaced during the quick plug-in and unplugging process and the shape of the upper connector is not deformed, it means that the friction force of the pressure plate 2 10 becomes smaller when clamping the upper connector, indicating that there is a problem with the test accuracy of the test tooling, and the alarm sub-module can be used to inform the staff to repair it.

[0036] Through the above steps, when the test fixture quickly plugs and unplugs the connector, the quality of the upper connector can be detected, and the test accuracy of the test fixture can be judged according to the clamping condition of the upper connector.
