Description

Technical Field

[0001] This utility model relates to the field of optical module testing technology, and more specifically, to an optical module testing system. Background Technology

[0002] Optical modules are optoelectronic devices that perform photoelectric and electro-optical conversion. The transmitting end of an optical module converts electrical signals into optical signals, and the receiving end converts optical signals back into electrical signals. They are commonly used in the backbone network of fiber optic networks. Optical modules need to be tested before leaving the factory. Traditional testing methods mainly involve manually inserting test modules into the optical modules. In this method, the optical modules and test modules are directly plugged in and out manually, making it difficult to precisely control the force applied. Since optical modules contain many gold fingers, improper insertion and removal force can easily damage the gold fingers of the optical module or the IC board in the test module, leading to product scrap or damage to the testing equipment.

Detailed Implementation

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0026] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please refer to Figures 1 to 9 This utility model provides an optical module testing system, including a rack 1, on which a robotic arm 2 is mounted. The robotic arm 2 is surrounded by a loading station 3, a barcode scanning station 4, an end-face inspection station 5, a plug-in / plug-out station 6, a testing station 7, and a unloading station 8. The robotic arm 2 is used to transfer materials between the loading station 3, the barcode scanning station 4, the end-face inspection station 5, the plug-in / plug-out station 6, the testing station 7, and the unloading station 8. The plug-in / plug-out station 6 is used to connect or disconnect optical modules from optical fibers. The barcode scanning station 4 is used to identify and acquire information about the optical modules. The end-face inspection station 5 is equipped with an end-face inspection instrument for performing end-face inspection on the materials. The testing station 7 is equipped with a high-low temperature detector 71 for testing the performance stability of the optical modules under different temperature environments.

[0029] In this embodiment of the invention, the system integrates multiple workstations such as loading, barcode scanning, end-point inspection, insertion / removal, testing, and unloading, covering all aspects of optical module testing. It enables comprehensive testing of optical modules within a single system, improving the continuity and systematic nature of the testing process. The system utilizes a robotic arm 2 to transfer materials between workstations. The robotic arm 2 precisely moves the optical modules between different workstations, ensuring that each optical module accurately reaches its corresponding workstation for operation. This automates the optical module testing process, reduces manual operation, improves testing efficiency and accuracy, and lowers labor costs and human error.

[0030] Specifically, robot arm 2 picks up the optical module from loading station 3, then passes it through barcode scanning station 4. Barcode scanning station 4 automatically identifies and acquires the optical module's information, facilitating tracking, management, and data recording, and providing convenience for subsequent analysis and traceability. Next, robot arm 2 carries the optical module to end-face inspection station 5. The end-face inspection instrument can accurately inspect the end face of the optical module, promptly detecting defects and contamination, ensuring the optical performance and connection quality of the optical module. Then, robot arm 2 takes the optical module that has passed the first two inspections to insertion / removal station 6 and places it down. Insertion / removal station 6 connects the optical module to the optical fiber. After connection, robot arm 2 picks up the optical module and sends it to testing station 7. The high and low temperature tester 71 on testing station 7 can simulate different temperature environments to test the performance stability of the optical module at different temperatures, helping to evaluate the reliability of the optical module in various practical application environments and improving product quality and adaptability. Finally, the robotic arm 2 removes the tested optical module and optical fiber, returns to the insertion / removal station 6 to separate the optical module from the optical fiber, and picks up the separated optical module and sends it to the unloading station 8 to complete the testing process.

[0031] With the above structural arrangement, each workstation is arranged around the robotic arm 2, resulting in a compact structure that saves space. This also facilitates the operation of the robotic arm 2 and the flow of materials, improving system efficiency. This modular design allows for system expansion and upgrades, enabling the addition or modification of workstations to meet the testing requirements of different types of optical modules and the needs of technological development.

[0032] Preferably, the end of the robotic arm 2 is provided with a mounting frame 21. The mounting frame 21 has a cuboid structure, and three sets of clamping fixtures and positioning devices 22 are provided on the four sides of the outer wall of the mounting frame 21. The positioning device 22 is used to position the optical module at the loading station 3. In this embodiment, the three sets of clamping fixtures are distributed on different surfaces of the mounting frame 21. The appropriate clamping fixture can be flexibly selected for gripping according to the specific placement angle and position of the optical module at the loading station 3, which increases the flexibility and adaptability of gripping and can better cope with optical modules with different placement postures. The positioning device 22 can position the optical module at the loading station 3, ensuring that the robotic arm 2 can accurately grip the optical module, reduce gripping errors, and improve the accuracy of subsequent testing processes. Installing the fixtures and devices on the outer wall of the mounting frame 21 makes the installation, disassembly, and maintenance of each component more convenient. If a clamping fixture or positioning device 22 malfunctions, it can be repaired or replaced directly from the outside without large-scale disassembly of the entire robotic arm 2, reducing maintenance costs and downtime.

[0033] Preferably, the three clamping fixtures are a first clamping fixture 23, a second clamping fixture 24, and a negative pressure adsorption fixture 25. The first clamping fixture 23 includes a first lifting mechanism 231 and a first electric gripper 232. The first electric gripper 232 is connected to the mounting frame 21 through the first lifting mechanism 231. The first electric gripper 232 is provided with a pair of gripping arms 233, which are used to clamp the optical module. The second clamping fixture 24 includes a second lifting mechanism 241 and a second electric gripper 242. The second electric gripper 242 is connected to the mounting frame 21 through the second lifting mechanism 241. The second electric gripper 242 is provided with a pair of gripping plates 243, which are used to clamp the optical module with a heat dissipation structure. The negative pressure adsorption device includes a third lifting mechanism 251 and a suction cup 252. The suction cup 252 is connected to the mounting frame 21 through the third lifting mechanism 251, and the suction cup 252 is used to adsorb the optical module.

[0034] In this embodiment, the three clamping fixtures are each equipped with an independent lifting mechanism, allowing each fixture to adjust its height independently according to actual needs. At different workstations or when facing optical modules of different heights, each fixture can flexibly rise and fall to a suitable position for operation, enhancing the system's adaptability and flexibility. Both the first clamping fixture 23 and the second clamping fixture 24 use electric grippers as the power source for clamping the workpiece. The electric grippers offer high precision in force and position control, allowing for accurate adjustment of the clamping force based on the specific characteristics of the optical module, avoiding damage to fragile or specially designed optical modules with heat dissipation structures. The suction cup 252 fixes the optical module using negative pressure adsorption, a method that does not cause mechanical damage to the surface of the optical module, making it particularly suitable for optical modules with smooth surfaces, irregular shapes, or high aesthetic requirements. The first lifting mechanism 231, the second lifting mechanism 241, and the third lifting mechanism 251 can employ cylinders or pneumatic slides to achieve the lifting and lowering of the corresponding fixtures.

[0035] During operation, a pair of clamping arms hold the two sides of the optical module, enabling the clamping of optical modules with conventional structures. A pair of clamping plates with a slightly smaller opening range can be used to clamp the heat dissipation fins on the top heat dissipation structure of the optical module, thus enabling the clamping of optical modules with heat dissipation structures. Suction cup 252 can be used to clamp optical modules with smooth surfaces, irregular shapes, or those requiring high aesthetic standards. In practical applications, the most suitable clamping fixture can be flexibly selected according to the different characteristics of the optical module and testing requirements, making the system compatible with various types of optical modules and expanding its applicability.

[0036] Preferably, the positioning device 22 includes a CCD camera 221 and a ring light source 222. The ring light source 222 is located below the CCD camera 221 and has a through slot in its center. The lens of the CCD camera 221 faces the through slot of the ring light source 222. In this embodiment, the CCD camera has the characteristics of high resolution and high sensitivity, and can clearly capture the image of the optical module at the loading station 3. By analyzing the image with advanced image processing algorithms, the position, angle, and size of the optical module can be accurately determined, providing a reliable basis for the subsequent precise grasping by the robotic arm 2. The ring light source 222 is arranged below the CCD camera and has a through slot in its center, which can evenly illuminate the optical module from all sides, effectively avoiding shadows and reflections caused by uneven lighting, ensuring the clarity and contrast of the image captured by the CCD camera 221, and further improving the positioning accuracy.

[0037] Preferably, the loading station 3 is equipped with a raw material tray 31, and the unloading station 8 is equipped with a barcode scanning end-inspection NG tray 81, a test NG tray 82, and a finished material tray 83. The raw material tray 31 is used to store optical modules waiting to be tested, the barcode scanning end-inspection NG tray 81 is used to store optical modules that failed to complete the tests at the barcode scanning station 4 and the end-inspection station 5, the test NG tray 82 is used to store optical modules that failed to complete the tests at the test station 7, and the finished material tray 83 is used to store optical modules that have passed all tests. In this embodiment, by setting different trays, such as the raw material tray 31 specifically for storing optical modules waiting to be tested, and trays for storing optical modules that failed at the barcode scanning station 4 and the end-inspection station 5 (barcode scanning end-inspection NG tray), failed at the test station 7 (test NG tray), and passed at the test station 7 (finished material tray 83), the optical modules can be clearly and orderly classified and managed. This facilitates the staff to quickly identify and process optical modules in different states, improving work efficiency. For optical modules that fail the test, they are stored in the NG (Not Good) tray for barcode scanning and the NG tray for testing, respectively. This makes it easy to determine at which testing stage the optical module failed during subsequent quality analysis and traceability, allowing for targeted investigation of the cause and implementation of improvement measures to enhance product quality. Furthermore, with all four trays concentrated on one side of frame 1, loading and unloading are more centralized, the working radius of the robotic arm 2 can be further reduced, and the overall machine occupies less space, resulting in a more compact structure.

[0038] Preferably, there are two insertion / removal stations 6, located on opposite sides of the robotic arm 2. Each insertion / removal station 6 includes a clamping module 61, a cleaning module 62, and an optical fiber pushing module 63. The clamping module 61 receives and clamps the optical module from the robotic arm 2. The cleaning module 62 works in conjunction with the clamping module 61 to clean the clamped optical module. The optical fiber pushing module 63 includes an optical fiber translation mechanism 631, a horizontal pressing unlocking mechanism 632, and a vertical pressing unlocking mechanism. 633; The fiber optic translation mechanism 631 drives the fiber optic cable to move horizontally and align with the optical module on the clamping module 61. The horizontal pressing unlocking mechanism 632 includes a pneumatic finger 6321 and a pair of pressing arms 6322. The pneumatic finger 6321 drives the pair of pressing arms 6322 to act on both sides of the optical module. The vertical pressing unlocking mechanism 633 includes a rotary cylinder 6331 and a pressing rod 6332. The rotary cylinder 6331 drives the pressing rod 6332 to rotate and then presses down vertically on the top of the optical module.

[0039] In this embodiment, two insertion / removal stations 6 are set on both sides of the robotic arm 2, enabling parallel operation. When one station is performing optical module insertion / removal operations, the other station can simultaneously process other optical modules, effectively reducing waiting time and greatly improving the overall efficiency of the testing system. The symmetrical distribution of the two insertion / removal stations 6 makes the layout of the entire system more compact and reasonable, making full use of the limited space.

[0040] The clamping module 61 receives and clamps the optical module delivered by the robotic arm 2, providing a stable foundation for subsequent cleaning and insertion / removal operations. The cleaning module 62 works in conjunction with the clamping module 61 to clean the clamped optical module. The cleanliness of the optical module is crucial to its connection performance with the optical fiber. Cleaning removes dust, impurities, and other contaminants from the surface of the optical module, reducing signal transmission loss and improving the performance and stability of the optical module.

[0041] The fiber optic translation mechanism 631 in the fiber optic push module 63 can move the fiber optic cable horizontally, precisely aligning it with the optical module on the clamping module 61. Precise alignment is crucial for a good connection between the optical module and the fiber optic cable. Therefore, the fiber optic translation mechanism 631 can utilize a high-precision electric dual-axis translation stage, an XY-axis displacement stage, or a two-dimensional electric translation stage, with a cylinder at the end for slow movement to achieve precise fiber insertion. After testing, the optical module needs to be unlocked. This embodiment includes a horizontal pressing unlocking mechanism 632 and a vertical pressing unlocking mechanism 633 to accommodate different types of optical modules. For example, the pneumatic fingers 6321 on the horizontal pressing unlocking mechanism 632 drive a pair of pressing arms 6322 to act on both sides of the optical module, enabling pressing operations on the unlocking mechanisms on both sides of the optical module. This horizontal pressing method can adapt to the unlocking requirements of side-unlocked optical modules, offering strong versatility and flexibility. The vertical press-to-unlock mechanism 633 uses a rotary cylinder 6331 to rotate the pressing rod 6332, which then presses vertically downwards onto the top of the optical module, achieving top-down unlocking of the optical module. This is suitable for optical modules that require unlocking from the top. By setting multiple unlocking methods, the system's compatibility with different types of optical modules is further improved.

[0042] Preferably, two scanning stations 4 are provided, located on opposite sides of the frame 1. Each scanning station 4 is equipped with a scanning frame 41, a camera 42, and a supplementary light 43. The scanning frame 41 is connected to the frame 1, the camera 42 is mounted on the scanning frame 41 with its shooting end facing upwards, and the supplementary light 43 is mounted on the scanning frame 41 and works in conjunction with the camera 42. The two scanning stations 4 share the scanning task, making the workload of each station relatively balanced, reducing the probability of failure that may occur at a single station due to long-term continuous operation, and improving the reliability and stability of the equipment.

[0043] Preferably, there are two test stations 7, which are located on both sides of the end-test station 5.

[0044] Preferably, the testing station 7 is further provided with a lifting platform 72; the lifting platform 72 includes a support base 721, a sliding base 722, a screw jack 723, a rotating base 724, a rotating shaft 725, a coupling 726, and a handwheel 727; the support base 721 is mounted on the frame 1, the sliding base 722 is disposed on the support base 721 and slidably connected to the support base 721; the screw jack 723 is mounted on the support base 721 and connected to the sliding base 722; the rotating base 724 is disposed on the support base 721, the rotating shaft 725 is rotatably disposed on the rotating base 724, one end of the rotating shaft 725 is connected to the screw jack 723 through the coupling 726, and the other end is fixedly connected to the handwheel 727; the high and low temperature detector 71 is mounted on the top of the sliding base 722. In this embodiment, the screw jack 723 is connected to the sliding seat 722. Power is transmitted to the screw jack 723 via the screw jack 723 through the rotating handwheel 727, which drives the rotating shaft 725 and then the coupling 726, allowing the sliding seat 722 to slide up and down on the support base 721. This allows the height of the high and low temperature detector 71 to be flexibly adjusted according to actual testing needs, adapting to the testing of optical modules of different sizes and placement heights, thus improving the versatility and adaptability of the testing system. Furthermore, the use of the handwheel 727 eliminates the need for complex electrical controls or additional power sources; operators can directly adjust the height of the high and low temperature detector 71 by manually rotating the handwheel 727, making operation simple and intuitive, and reducing operational difficulty. The lifting platform 72 has a compact design and does not occupy excessive space when installed on the testing station 7. Through reasonable layout and structural design, while achieving height adjustment, it effectively utilizes the limited testing space, making the spatial layout of the entire testing system more rational.

[0045] Preferably, the maximum working radius of the robotic arm 2 is 700-750mm, and the load capacity is 7kg. In this embodiment, while ensuring a working radius of 700-750mm and a load capacity of 7kg, the design of the robotic arm 2 can be relatively compact. A smaller working radius helps to reduce the length and weight of the robotic arm 2, thereby improving the structural stability and motion accuracy of the robotic arm 2. At the same time, the moderate load capacity also means that the drive system and support structure of the robotic arm 2 do not need to be too large and complex, reducing equipment costs and maintenance difficulty.

[0046] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model covers all aspects of optical module testing by setting up a loading station, a barcode scanning station, an end-inspection station, a plug-in / plug-out station, a testing station, and a unloading station. A robotic arm is used to transfer materials between these stations, automating the optical module testing process, reducing manual operation, improving testing efficiency and accuracy, and lowering labor costs and human error. Furthermore, the station layout around the robotic arm is compact, saving space and facilitating robotic arm operation and material flow, thus improving system operating efficiency. This utility model has a compact structure and occupies little space, making it particularly suitable for applications with high site and floor space requirements. It also places low load requirements on the robotic arm, offers high operational precision, and has low equipment costs, effectively improving equipment efficiency.
