Description

Technical Field

[0001] The utility model relates to the technical field of automatic detection equipment, and more specifically, to an optical module detection system. Background Art

[0002] Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversions. The transmitting end of an optical module converts electrical signals into optical signals, and the receiving end converts optical signals into electrical signals. They are commonly used in the backbone network of fiber optic networks. In the existing optical module inspection process, the optical module to be inspected is placed at the inspection station. A person wearing anti-static gloves and an anti-static wristband then grasps the optical module. During the grasping process, the optical module must be protected from bumps, especially from contact with the gold fingers on the optical module. The optical fiber head is manually inserted into the rear interface of the optical module, and the head of the optical module is then inserted into the designated jack of the switch. The insertion process should be gentle, and a "click" sound indicates that it is fully inserted. After the inspection is complete, the optical module needs to be removed from the switch jack. Remove the optical module slowly and avoid pulling it hard to avoid damaging the internal components.

[0003] In the existing optical module inspection process, manual loading and unloading is generally adopted, and manual inspection of optical modules is performed, which limits the inspection efficiency. On the other hand, manual operation has many uncertainties, which have a great impact on the inspection quality. For example, during manual loading and unloading and plugging and unplugging, the force is difficult to control accurately, and collisions are prone to occur, which poses a great risk of damage to the product and the testing machine.

[0029] In an embodiment of the present invention, optical modules 12 are stored according to their types in a loading module 2 for testing, a discharge module 3 for qualified products, and a discharge module 4 for defective products. The loading module 2 for testing stores optical modules 12 ready for testing, the discharge module 3 for qualified products stores optical modules 12 that have passed testing, and the discharge module 4 for defective products stores defective products. "NG" stands for "Not Good," and refers to products that have minor cosmetic flaws or do not meet the original specifications after manufacturing. In this embodiment, products that fail testing are classified as "NG." For this purpose, an "NG" discharge module 4 is provided to store defective products that fail testing.

[0030] The robot loading and unloading module 5 includes a base 501, a six-axis robot 502, and an end fixture 503. The base 501 is mounted on the six-axis robot 502. The last joint of the six-axis robot 502 docks with the end fixture 503. The end fixture 503 is used to clamp the optical module 12. Clamping methods include but are not limited to vacuum suction, gripping with a gripper, and electromagnetic adsorption. After the end fixture 503 grasps the optical module 12, it is driven by the six-axis robot 502 to quickly transfer the optical module 12 between the various modules in this embodiment.

[0031] The lower visual code scanning module 6 is used to scan and identify the identification code or QR code on the optical module 12, thereby selecting the corresponding test mode based on the type and model of the optical module 12 and more quickly performing data statistics. By adopting the code scanning and recognition method, the robot loading and unloading module 5 only needs to drive the optical module 12 past the lower visual code scanning module 6 to quickly identify the optical module 12 being tested.

[0032] After optical module 12 is identified, its end needs to be inspected. This process uses an end inspection instrument 10, which is loaded and unloaded by the end inspection loading and unloading module 7. The robotic loading and unloading module 5 simply delivers the scanned optical module 12 to the end inspection loading and unloading module 7. The module then receives the optical module 12 and inserts it into the end inspection instrument 10 for inspection. After inspection, the robotic loading and unloading module 5 re-grabs the optical module 12 and transfers it to the plug-in cleaning module 8.

[0033] The plug-in cleaning module 8 includes a front-end clamping module 801, a cleaning box 802, and a rear-end plug-in cleaning module 803. The front-end clamping module 801 is used to receive the optical module 12 after being inspected by the end detector 10. The rear-end plug-in module 803 clamps the optical fiber head 13, then sends the optical fiber head 13 to the cleaning box 802 for wiping and cleaning, and then aligns the cleaned optical fiber head 13 with the tail of the optical module 12 for docking. After docking, the robot loading and unloading module 5 grabs the optical module 12 with the optical fiber head 13 inserted and sends it to the high and low temperature tester 9 for testing. After the test is completed, the robot loading and unloading module 5 removes the optical module 12 and sends it to the plug-in cleaning module 8 to separate the optical module 12 and the optical fiber head 13. Finally, the robot loading and unloading module 5 sends the optical module 12 to the good product unloading module 3 or the bad product unloading module 4 based on the test results.

[0034] The working principle of this utility model is as follows:

[0035] The robot loading and unloading module 5 grabs the optical module 12 from the material loading module 2 to be tested, moves it to the lower visual code scanning module for scanning, and then places the optical module 12 on the end inspection loading and unloading module 7. After the test is completed, the robot loading and unloading module 5 grabs the tested optical module 12 on the end inspection loading and unloading module 7 and places it on the plug-in cleaning module 8 (the plug-in cleaning module 8 completes the process: cleaning the optical fiber head 13 and inserting the optical fiber head 13 into the end of the optical module 12). Subsequently, the robot loading and unloading module 5 clamps the optical module 12 with the optical fiber head 13 inserted, moves to the high and low temperature tester 9 to exchange materials, removes the tested material, and inserts the material to be tested into the test port for testing; after the robot loading and unloading module 5 clamps the tested material, it places it on the plug-in cleaning module 8 to pull out the optical fiber head 13, and places qualified products on the good product unloading module 3 and NG products on the NG product unloading module 4 according to the test results.

[0036] Preferably, there are two sets of plug-in cleaning modules 8 and two high-low temperature testers 9, and the plug-in cleaning modules 8 and the high-low temperature testers 9 are arranged in coordination with each other. To improve testing efficiency and facilitate the exchange of materials between different processes, this embodiment provides two sets of plug-in cleaning modules 8 and high-low temperature testers 9, reducing downtime waiting for testing and enabling multiple processes to run alternately, greatly improving testing efficiency.

[0038] During this process, when removing material from the test material loading module 2, the CCD visual positioning device 5033 visually locates the material. Once located, the material is picked up by the vacuum suction device 5034. The vacuum suction device 5034 carries the material through the lower visual barcode scanning module 6 for scanning before depositing it at the end-of-line inspection loading and unloading module 7. After the end-of-line inspection instrument 10 completes testing, the six-axis robot 502 rotates and switches to the first electric gripper 5035. The electric gripper assembly 50352 grasps the material and delivers it to the plug-in cleaning module 8 for processing. Subsequently, the first electric gripper 5035 retrieves the processed material, while the second electric gripper 5036 removes the tested material from the high and low level tester, freeing up the test port. The test material on the first electric gripper 5035 can then be inserted into the test port for testing. The second electric gripper 5036 carries the tested material back to the plug-in cleaning module 8 for unloading and processing. Finally, the processed material is delivered to different unloading modules based on the test results.
