[0022] 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.

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.
[0024] 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.
[0025] Please refer to Figures 1 to 6 This utility model provides an automatic loading and unloading end-face inspection device for optical modules, including a workbench 1. The workbench 1 is equipped with a loading station 2, an NG material station 3, an unloading station 4, a robot arm 5, a rotating module 6, a three-axis module 7, and an optical fiber end-face inspection instrument 8. A tray storage compartment 9 is provided below the workbench 1. The robot arm 5 is used to grab and move materials. The loading station 2 is used to place materials to be inspected. The NG material station 3 is used to place materials that have failed inspection. The unloading station 4 is used to place materials that have passed inspection. The rotating module 6 is connected to the three-axis module 7 and is used to receive materials from the robot arm 5 and flip the materials toward the optical fiber end-face inspection instrument 8. The three-axis module 7 is used to drive the rotating module 6 to move along the X-axis, Y-axis, and Z-axis directions. The optical fiber end-face inspection instrument 8 is used to perform end-face inspection on the materials.
[0026] In this embodiment of the invention, the optical module end-face inspection device achieves an automated inspection process through multi-station collaboration with the module. Specifically, the optical module material to be inspected is placed in the loading station 2, and the pallet storage compartment 9 below the workbench 1 provides empty pallets or replenished materials. The robotic arm 5 picks up the optical module to be inspected from the loading station 2, moves it along a preset path to above the rotating module 6, and places the material on the bearing position of the rotating module 6.
[0027] The rotating module 6 can rotate the material and change its direction, working in conjunction with the robotic arm 5 to receive the material, and then feeding it to the fiber optic end-face inspector 8. After the rotating module 6 receives the material, it flips the optical module according to the inspection requirements, for example, adjusting the angle so that the end face faces the inspection port of the fiber optic end-face inspector 8, ensuring accurate inspection position. The three-axis module 7 drives the rotating module 6 to move along the X, Y, and Z axes, precisely adjusting the relative position between the optical module and the fiber optic end-face inspector 8, allowing the optical module material to enter the inspection area of the fiber optic end-face inspector 8.
[0028] The fiber optic end-face inspection instrument 8 performs high-definition imaging or laser scanning on the end face of the optical module, detecting defects such as contaminants, scratches, and flatness. The inspection data is transmitted to the control system in real time and compared with preset standards to determine whether the material is qualified. After inspection, the three-axis module 7 and the rotary module 6 move the material back to a position easily grasped by the robotic arm 5. When the material passes inspection, the robotic arm 5 picks it up from the rotary module 6 and transfers it to the OK unloading station 4, placing it on the qualified product tray. If the inspection fails, the robotic arm 5 transfers the material to the NG unloading station 4 for separate storage for subsequent processing. In this embodiment, the NG unloading station 4 is used to store NG materials, which refer to materials or products that are deemed unqualified during the production process. These materials typically have quality defects (such as incorrect dimensions, substandard performance, or appearance flaws) and cannot meet production standards or customer requirements, requiring separate isolation, rework, or scrapping. Conversely, qualified products are also called OK materials, and the OK unloading station 4 stores OK materials that have passed inspection and meet quality requirements.
[0029] After a single inspection is completed, the three-axis module 7 and the rotary module 6 reset, and the robotic arm 5 returns to the loading station 2 to pick up new materials, repeating the above process to achieve continuous automated inspection. Through the above structural setup, the spatial motion coordination between the robotic arm 5, the rotary module 6, and the three-axis module 7 enables automatic loading and unloading of optical module materials. Combined with the high-precision judgment of the optical fiber end face detector, the entire process from material picking and inspection to sorting is automated, greatly improving inspection efficiency.
[0030] Preferably, the three-axis module 7 includes an X-axis translation component 701, a Z-axis translation component 702, and a Y-axis lifting component 703. The X-axis translation component 701 is mounted on the worktable 1, and the Z-axis translation component 702 is mounted on the X-axis translation component 701. The X-axis translation component 701 drives the Z-axis translation component 702 to move along the X-axis direction. The Y-axis lifting component 703 is mounted on the Z-axis translation component 702, and the Z-axis translation component 702 drives the Y-axis lifting component 703 to move along the Y-axis direction. The rotation module 6 is mounted on the Y-axis lifting component 703, and the Y-axis lifting component 703 drives the rotation module 6 to move along the Y-axis direction. In this embodiment, the X-axis, Y-axis, and Z-axis all refer to the corresponding X, Y, and Z coordinate axes in a Cartesian coordinate system, where the X-axis represents horizontal movement, the Z-axis represents translation perpendicular to the X-axis direction, and the Y-axis represents vertical up-down movement. The rotating module 6 receives the material delivered by the robotic arm 5 through its own rotation. The material is then swung and rotated to align with the fiber optic end-face inspector 8. Through the coordinated operation of the X-axis translation component 701, the Z-axis translation component 702, and the Y-axis lifting component 703, the material is accurately moved to the designated position on the fiber optic end-face inspector 8 to meet the inspection requirements. After inspection, the module moves in the reverse direction, the robotic arm 5 removes the inspected material, and then sends the uninspected material to the rotating module 6, thus achieving continuous inspection operations in a cyclical manner.
[0031] Preferably, the Y-axis lifting assembly 703 is equipped with a CCD module 704, which is used to identify and acquire information about the material. In this embodiment, the CCD module 704 is an image sensor module based on a charge-coupled device (CCD), which can convert optical images into electrical signals and further into digital signals for processing and analysis by a computer or other equipment. In this embodiment, the optical module to be detected is grasped by the robotic arm 5 and moved directly above the CCD module 704. The cleaning end of the CCD module 704 faces upward to photograph the optical module and acquire image information (such as QR codes, model identification, surface defects, dimensional features, etc.) to achieve the effect of identifying the optical module. This facilitates the registration and identification of the optical module, enabling the recording, storage, and retrieval of key information during the product cleaning process, and achieving traceability of the detection process.
[0032] Preferably, the rotating module 6 includes a fixed base 601, a reducer 602, a servo motor 603, a rotating plate 604, and a clamp 605; the fixed base 601 is connected to the Y-axis lifting assembly 703; the reducer 602 is mounted on the fixed base 601, the servo motor 603 is mounted on the reducer 602, the output end of the servo motor 603 is connected to the reducer 602, the output end of the reducer 602 is connected to the rotating plate 604, and the clamp 605 is disposed on the rotating plate 604. In this embodiment, the fixed base 601 is connected to the Y-axis lifting assembly 703 to achieve three-axis positioning of the entire rotating module 6. After being combined with the Y-axis lifting assembly 703, the rotating module 6 can synchronously adjust the rotation angle during translation and lifting to meet the needs of receiving materials and aligning materials with the cleaning module. In this embodiment, a servo motor 603 is used as the power source. The servo motor 603 provides precise speed and position control, while the reducer 602 reduces the speed and amplifies the torque through gear transmission, ensuring that the rotating plate 604 drives the clamp 605 to achieve low-speed, high-torque, and high-positioning-accuracy rotational motion. Furthermore, the servo motor 603 has rapid start-stop and acceleration / deceleration characteristics, enabling rapid reversal of the rotating plate 604. The rotating plate 604 serves as the mounting platform for the clamp 605, and suitable clamps 605 (such as vacuum adsorption, pneumatic grippers 6051, electric grippers 6051, magnetic clamps 605, etc.) can be selected according to the material's shape and size to adapt to different materials.
[0033] Preferably, the clamp 605 includes a gripper 6051, and the gripper 6051 is provided with a pair of clamping arms 6052. The gripper 6051 drives the pair of clamping arms 6052 to move closer or separate from each other. In this embodiment, the gripper 6051 drives the pair of clamping arms 6052 to move closer or separate synchronously along a preset trajectory. The two arms approach until they contact the material surface, and fix the material by friction or mechanical locking to receive the material conveyed by the robot arm 5. When the detection is completed and the material needs to be released, the two arms separate, releasing the constraint on the material. The robot arm 5 then picks up the material and places the next material to be detected into the clamping arm 6052, completing the exchange of raw and cooked materials.
[0034] Preferably, the gripper 6051 is an electric gripper 6051 or a pneumatic gripper 6051.
[0035] Preferably, the bottom of the fiber optic end-face inspection instrument 8 is provided with a shock-absorbing device 10, and the fiber optic end-face inspection instrument 8 is connected to the worktable 1 through the shock-absorbing device 10. In this embodiment, by setting the shock-absorbing device 10, through elastic support or damping design, the fiber optic end-face inspection instrument remains stable during operation, reducing the impact of external vibration on the inspection accuracy, and ensuring clear fiber optic end-face images and accurate data.
[0036] Preferably, the vibration damping device 10 includes a damping plate 1001 and four shock absorbers 1002, and the fiber optic end face detector 8 is mounted on the top surface of the damping plate 1001. The damping plate 1001 is configured as a rectangular or square structure, and the four shock absorbers 1002 are respectively located at the four bottom corners of the damping plate 1001. A shock absorber is a device used to reduce vibration and shock in mechanical systems. It is usually composed of components such as springs, dampers, and housings. Its main function is to absorb and eliminate vibration energy, protecting equipment or structures from damage caused by vibration and impact. It can also reduce noise and improve production efficiency. In this embodiment, the rectangular or square damping plate 1001, combined with the four shock absorbers 1002 at the four bottom corners, forms a symmetrical support structure, effectively buffering external vibration and reducing detection errors caused by vibration in the cleaning module. The modular design facilitates quick installation of the detector, and the symmetrical layout adapts to various equipment spaces, improving stability without occupying too much installation space.
[0037] Preferably, the robotic arm 5 includes a six-axis robot and a gripper module. The six-axis robot is mounted on the worktable 1, and the gripper module is mounted on the end effector of the six-axis robot. With this structural configuration, the six-axis robot can handle materials along complex paths, and the gripper module can rotate freely with the robot's end effector axis (sixth axis), ensuring that the material maintains its optimal posture during gripping and movement. Furthermore, the gripper module can be equipped with cylinders, suction cups, grippers 6051, magnetic suction devices, etc., to grasp materials, and sensors can also be installed to detect the material's position for precise gripping.
[0038] Preferably, the workbench 1 is further provided with a storage rack 11, and the storage rack 11 is provided with replacement grippers 12, and there are multiple sets of replacement grippers 12; the storage rack 11 limits the replacement grippers 12 on the workbench 1. The design of setting up a storage rack 11 on the workbench 1 and limiting multiple sets of replacement grippers 12 effectively improves the flexibility and efficiency of loading and unloading through modular quick-change, flexible production adaptation, and efficient space utilization. Specifically, when the production line needs to switch to produce materials of different specifications (such as optical modules of different sizes, optical modules with heat dissipation components, or other irregularly shaped components), the robot arm 5 can select the corresponding specification of replacement gripper 12 from the storage rack 11 and quickly complete the installation through a quick-change interface (such as a pneumatic or electromagnetic locking device).
[0039] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up a loading station, an unloading station, a robot arm, a rotating module, a three-axis module, and a fiber optic end-face inspection instrument. The robot arm delivers the material to the rotating module, and the rotating module and the three-axis module drive the material into the fiber optic end-face inspection instrument for end-face inspection. After inspection, the rotating module and the three-axis module drive the material away from the fiber optic end-face inspection instrument, and the robot arm moves the inspected material to the corresponding station. This utility model realizes the automation of optical module end-face testing, reduces manual operation, allows for continuous and uninterrupted loading and unloading, and has high positioning accuracy and high inspection efficiency, greatly reducing labor costs and human error.
