DETAILED DESCRIPTION

[0055] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0056] Referring to Figure 1 , Figure 2 and Figure 3 , the present application provides a high and low temperature environment optical cable mechanical property test system, which comprises a test box, a test device, a display device and a control device, wherein the test box is provided with a temperature and humidity adjusting device for adjusting the temperature and humidity in the test box, the temperature and humidity in the test box can be adjusted by the temperature and humidity adjusting device to meet the required test temperature and humidity, the temperature and humidity adjusting device can be an existing device, the test box is also provided with a wire hole through which the optical cable 5 passes, a sealing ring can be installed on the wire hole to improve the sealing effect, the optical cable can be connected with an optical cable strain tester after passing through the wire hole for testing, and a test table 9 is arranged in the test box.

[0057] The test device is located in the test box and is installed on the test table 9, and the test device comprises two clamping mechanisms 1, two traction mechanisms 2, a collision impact mechanism 3 and a visual detection mechanism 4, the two clamping mechanisms 1 are distributed at intervals, the two traction mechanisms 2 are located between the two clamping mechanisms 1, the collision impact mechanism 3 is located between the two traction mechanisms 2, the visual detection mechanism 4 is located between the two traction mechanisms 2, and the visual detection mechanism 4, the collision impact mechanism 3, the two traction mechanisms 2 and the two clamping mechanisms 1 are arranged in a linear type.

[0058] The visual detection mechanism 4 can use a camera or other equipment to take images, and the images after testing can be compared with qualified appearance images and sent to the control device.

[0059] The control device is connected with the clamping mechanism 1, the traction mechanism 2, the collision impact mechanism 3, the visual detection mechanism 4 and the display device, generates a test report according to the data detected by the optical cable strain tester and the visual detection mechanism 4, and displays the test report through the display device.

[0060] In use, a sufficiently long optical cable 5 is reserved in the test chamber for testing. Then, both ends of the optical cable 5 are passed out of the test chamber and connected to the optical cable strain tester. The optical cable 5 in the test chamber can be threaded onto the clamping mechanism 1 and the traction mechanism 2. The temperature and humidity required for the test are set by the temperature and humidity adjustment device. The two traction mechanisms 2 are controlled by the control device to straighten the optical cable 5. Then, the impact mechanism 3 is controlled to perform an impact test or a flattening test. After the impact or flattening, the traction mechanism 2 is controlled again to pull the optical cable 5 to bring the impacted or flattened area of ​​the optical cable 5 into the field of view of the visual inspection mechanism 4 for imaging. In addition, data such as power are measured by the optical cable strain tester. The control device compares the image after the test with the qualified appearance image and the data measured by the optical cable strain tester, outputs a test report on the impact test or flattening test, and displays it through the display device. In addition, the control device controls one of the clamping mechanisms 1 to clamp the optical cable 5, and the other clamping mechanism 1 to release the optical cable 5. One or two traction mechanisms 2 are controlled to pull the optical cable 5 towards the side of the clamping mechanism 1 that has released the optical cable 5 to perform a tensile test. After that, the optical cable 5 is released, and the traction mechanism 2 is controlled again to pull the optical cable 5 to bring the stretched area on the optical cable 5 into the field of view of the visual inspection mechanism 4 for imaging. In addition, data such as power are measured by the optical cable strain tester. The control device compares the image after the test with the qualified appearance image and the data measured by the optical cable strain tester, outputs a test report on the tensile test, and displays it through the display device.

[0061] As can be seen, in this application, the test does not need to be taken out of the high and low temperature chamber before testing. The test can be carried out directly in the test chamber, which can ensure the temperature and humidity during the test and improve the reliability of the test results.

[0062] In addition, since the various testing devices are controlled by a control device to carry out the corresponding tests, human error can be avoided to a certain extent, thus further improving the reliability of the test results.

[0063] To make this application more intelligent and automated, reduce labor intensity, and achieve automatic testing, the control device in this application includes a control module and a control panel connected to the control module. The control panel is used to select and / or input test types and test conditions; that is, the control panel can provide test types and test conditions for users to select, and can also provide input boxes for input.

[0064] For example, the control panel provides a two-level interface. The first-level interface displays the test types, which include impact test, flattening test, bending test, torsion test, and tensile test.

[0065] After the test type is selected, a secondary interface is jumped to, and corresponding test conditions are displayed.

[0066] For example, for the impact test, the test conditions include the type of impact head, the impact energy size, the impact test number, the optical cable impact position, etc.

[0067] For the crushing test, the test conditions include the type of crushing head, the extrusion force size, the extrusion time, the extrusion test number, the optical cable extrusion position, etc.

[0068] For the bending test, the test conditions include the bending radius, the bending number of turns, the bending test number, etc.

[0069] For the torsion test, the test conditions include the torsion angle, the torsion test number, the torsion speed, etc.

[0070] For the stretching test, the test conditions include the stretching force size, the stretching time, the stretching test number, etc.

[0071] The control module controls the clamping mechanism 1, the traction mechanism 2, the impact mechanism 3, the visual detection mechanism 4 and the display device to work according to the selected or input test type and test conditions, so as to perform corresponding test tests.

The bearing seat 10 is installed on the test table 9, the bearing 11 is installed on the bearing seat 10, the clamping head 12 is installed on the bearing 11, and the sixth driver is connected with the clamping head 12 and is used to drive the clamping head 12 to rotate and to clamp or loosen the optical cable 5 passing through the clamping head 12.

[0073] In this application, the sixth driver is used to drive the clamping head 12 to rotate, so as to realize the torsion test. The clamping head 12 can clamp or loosen the optical cable 5 passing through the clamping head 12, so as to realize the clamping purpose. It can be understood that the above-mentioned clamping head 12 adopts the existing equipment, and the specific structure and the principle of driving the clamping head 12 to clamp or loosen the optical cable 5 passing through the clamping head 12 by the sixth driver will not be described herein.

[0074] When the torsion test is performed, the control device controls the two traction mechanisms to release the optical cable 5, controls the two clamping heads 12 to clamp the optical cable 5, and then controls one clamping head 12 to rotate or controls the two clamping heads 12 to rotate in opposite directions to perform the torsion. After the completion, the optical cable 5 is released, and the traction mechanism 2 is controlled again to traction the optical cable 5 to the shooting field of the visual detection mechanism 4, and the shooting is performed. In addition, the data such as power is measured by the optical cable strain tester. The control device compares the test image with the qualified appearance image and the data measured by the optical cable strain tester, outputs the test report of the torsion test, and displays the test report through the display device.

The first mounting plate 200 of the lower belt wheel assembly 20 is mounted on the test table 9, and the two driving wheels 201 are sleeved with a belt 202. The second driver 21 is mounted on the first mounting plates 200 of the two belt wheel assemblies 20 and is used to drive one of the belt wheel assemblies 20 to move, so that the belt 202 of the belt wheel assembly 20 is close to or away from the belt 202 of the other belt wheel assembly 20 to clamp or release the optical cable 5. The driving wheels 201 can be forward or reverse rotated as needed.

[0076] Since the part of the belt 202 between the two driving wheels 201 is relatively soft, in order to better clamp the optical cable 5 by the two belt wheel assemblies 20 above and below, and to achieve the traction effect, referring to Figure 2 , the belt wheel assembly 20 further includes an auxiliary wheel 203 located between the two driving wheels 201 and attached to the side of the belt 202 close to the belt 202 of the other belt wheel assembly 20.

[0077] In order to better adjust the two belt wheel assemblies 20 to clamp or release the optical cable 5, referring to Figure 3 , a guide assembly 22 for guiding one of the belt wheel assemblies 20 to move close to or away from the other belt wheel assembly 20 is further mounted between the two belt wheel assemblies 20. The lifting of the belt wheel assembly 20 is guided by the guide assembly 22, which ensures the stability of the traction mechanism 2.

[0078] Further, the guide assembly 22 can be provided with one or more, for example, referring to Figure 3As shown, the guide assembly 22 is provided with two, wherein the guide assembly 22 comprises a first guide rod 221 and two mounting blocks 220, two mounting blocks 220 are respectively mounted on the first mounting plate 200 of two pulley assemblies 20, one end of the first guide rod 221 is fixed on one of the mounting blocks 220, and the other end is movably arranged in the other mounting block 220, so that the mounting block 220 and the first guide rod 221 move relatively, thereby adjusting the position of the mounting block 220 on the first guide rod 221.

[0079] As shown in Figure 1 , Figure 2 and Figure 3 As shown, the impact mechanism 3 comprises a second mounting plate 30, two second guide rods 31, a third mounting plate 32, a base 33 and a third driver 34; two second guide rods 31 are vertically mounted on the test bench 9 and are spaced apart, the top of the second guide rod 31 is mounted on the second mounting plate 30; the third mounting plate 32 is arranged on the two second guide rods 31 and is located below the second mounting plate 30, and the third mounting plate 32 is provided with a mounting position for detachably mounting the impact head 6 or the extrusion head; the mounting position can be designed as a threaded hole, and the impact head 6 or the extrusion head can be threadedly connected on the threaded hole; the base 33 is located directly below the mounting position, and during the test, the optical cable 5 is placed on the base 33 to perform the impact or flattening test; the third driver 34 is mounted on the second mounting plate 30, and it is connected with the third mounting plate 32 and used to drive the third mounting plate 32 to move up and down.

[0080] The third driver 34 is controlled to work by the control device, so that the third mounting plate 32 with the impact head 6 or the extrusion head moves downward to impact or flatten the optical cable 5 on the base 33.

[0081] In order to realize test automation, as shown in Figure 1 and Figure 2 The test device further comprises a manipulator 7, and the control device is further connected with the manipulator 7 and used to control the manipulator 7 to detach or mount the impact head 6 or the extrusion head.

[0082] It can be understood that the impact head 6 and the extrusion head are both of multiple different types, and according to the actual test needs, the appropriate type of impact head 6 or extrusion head is selected by the manipulator 7 to be mounted, so as to complete the corresponding test.

[0083] In order to realize the bending test, as shown in Figure 2 and Figure 3As shown, the test device further comprises a first guide rail, a bending mechanism 8, a fourth driver, and a mechanical arm 7, the first guide rail is arranged on the test table 9, the bending mechanism 8 is movably arranged on the first guide rail, the fourth driver is connected with the bending mechanism 8 and is used to drive the bending mechanism 8 to move along the first guide rail to a position between two traction mechanisms 2 or to retreat to the initial position to avoid affecting other tests; wherein the control device is connected with the fourth driver and the mechanical arm 7, and is used to control the fourth driver to work and control the mechanical arm 7 to wind the optical cable 5 on the bending mechanism 8.

[0084] During the bending test, the control device controls the fourth driver to work to make the bending mechanism 8 move to a position between two traction mechanisms 2. Then the control device controls the mechanical arm 7 to wind the optical cable 5 on the bending mechanism 8, controls the clamping mechanism 1 to release the optical cable 5, uses the traction mechanism 2 to pull, so as to tighten the optical cable 5, and then controls the clamping mechanism 1 to clamp the optical cable 5 and releases the traction mechanism 2. After the test is completed, a picture is taken, and data such as power is measured by the optical cable strain tester. The control device compares the test image with the qualified appearance image and the data measured by the optical cable strain tester, outputs a test report about the bending test, and displays the test report through the display device.

[0085] Referring to Figure 2 As shown, the bending mechanism 8 comprises a vertical plate 80 and a plurality of guide rollers 81, the guide rollers 81 are vertically installed on the plate surface of the vertical plate 80, and each guide roller 81 is located on a virtual circle.
