Description

Technical Field

[0001] This invention relates to the field of optical module cleaning technology, and in particular to an end-face cleaning and testing device for optical modules. Background Technology

[0002] With the rapid development of 5G and AI technologies, the quality requirements for optical modules are becoming increasingly stringent. The manufacturing process of optical modules involves cleaning and inspecting the LC & MTP endfaces. If the fiber endfaces of the optical module are dirty or damaged before leaving the factory, it directly affects the product's optical transmission and reception performance, leading to a decrease in yield.

[0003] For example, Chinese utility model patent CN216397373U, with an authorization announcement date of April 29, 2022, discloses a cleaning device for optical module ports. Specifically, it includes a housing with a fiber optic wiping rod mounting port, a cleaning agent spray port, and an air blowing port. The air blowing port outputs compressed air outward through an air blowing assembly installed inside the housing. Inside the housing is a fiber optic wiping rod drive assembly for driving the fiber optic wiping rod to rotate, which is detachably mounted at the fiber optic wiping rod mounting port, and a spraying assembly for spraying cleaning agent through the cleaning agent spray port. The device uses sprayed cleaning fluid to clean the surface of the optical module ports, the rotating fiber optic wiping rod for wiping, and finally, compressed air is blown out to dry any remaining cleaning agent, making the cleaning of optical modules more convenient and effective.

[0004] Existing cleaning equipment cleans fiber optic ports, but the cleaned optical modules still need to be manually transferred to a testing machine to inspect the cleaning effect. If the cleaning effect is unsatisfactory, the optical modules need to be cleaned again. Therefore, the cleaning and testing processes of optical modules are handled separately, resulting in low work efficiency and an inability to guarantee the product quality of optical modules. Summary of the Invention

[0005] The technical problem that this invention aims to solve is that existing cleaning equipment requires manual transfer of optical modules to a testing machine after cleaning, and then the surface cleaning effect is tested. The cleaning and testing processes of optical modules are handled separately, resulting in low work efficiency and failing to guarantee the product quality of optical modules.

[0006] To address the aforementioned technical problems, this invention provides an end-face cleaning and inspection device for optical modules:

[0007] The end-face cleaning and testing equipment for optical modules includes a main unit, a feeding mechanism, a moving mechanism, and a fixed frame. The feeding mechanism, the moving mechanism, and the fixed frame are all mounted on the main unit, and the moving mechanism and the fixed frame are arranged at intervals relative to each other.

[0008] The moving mechanism is equipped with a product fixing structure, a cleaning rod gripping structure, and a cleaning liquid injector. The product fixing structure has a positioning part on one side of the fixing frame, the cleaning rod gripping structure has a gripper on one side of the fixing frame, and the cleaning liquid injector has an injection port on one side of the fixing frame, so that the cleaning rod can be inserted into the injection port to absorb the cleaning liquid.

[0009] The fixed frame is equipped with a cleaning rod rotating mechanism, a spray suction cleaning mechanism and an end face detection structure. The cleaning rod rotating mechanism is provided with a clamping head on one side corresponding to the moving mechanism. The clamping head is used to detachably clamp the cleaning rod.

[0010] The spray-suction cleaning mechanism is provided with a spray-suction head on one side corresponding to the moving mechanism. The spray-suction head is used to spray cleaning fluid onto the end face of the optical module and to draw up the cleaning fluid. The end face detection structure is provided with a detection lens on one side corresponding to the moving mechanism. The detection lens is used to perform visual inspection on the end face of the optical module.

[0011] The end-face cleaning and inspection equipment for the optical module also includes a display screen, which is electrically connected to the end-face inspection structure to display a magnified image of the end-face of the optical module after cleaning.

[0012] Furthermore, the product fixing structure is installed on one side of the moving mechanism, and the positioning part protrudes from the gripper and the liquid injection port in the direction close to the fixing frame; the clamping head, the spray suction head and the detection lens are respectively set at the same horizontal height corresponding to the positioning part.

[0013] Furthermore, the main unit has intersecting X and Y directions, the moving mechanism and the fixed frame are distributed relative to each other along the Y direction, the product fixing structure, the cleaning rod gripping structure and the cleaning liquid injector are arranged along the X direction on the moving mechanism, and the cleaning rod rotating mechanism, the spray suction cleaning mechanism and the end face detection structure are arranged along the X direction on the fixed frame.

[0014] Furthermore, the moving mechanism includes an X-axis moving mechanism and a Y-axis moving mechanism. The X-axis moving mechanism is arranged parallel to the length direction of the fixed frame. The X-axis moving mechanism is used to drive the product fixing structure, the cleaning rod gripping structure, and the cleaning liquid injector to switch positions along the X-axis.

[0015] The Y-axis moving mechanism is arranged parallel to the width direction of the fixed frame. The Y-axis moving mechanism is used to drive the product fixing structure, the cleaning rod gripping structure and the cleaning liquid injector to move closer to or away from the fixed frame along the Y direction.

[0016] Furthermore, the positioning part is a positioning groove, and the positioning groove has an opening on one side corresponding to the fixing frame. A limiting member is installed at the opening of the positioning groove, and the limiting member is used to press and cooperate with the end face of the optical module.

[0017] Furthermore, the opening direction of the positioning groove is arranged parallel to the width direction of the fixing frame, the limiting member is an L-shaped limiting member, the L-shaped limiting member is movably assembled at the opening of the positioning groove, and the L-shaped limiting member has a cleaning window on the side of the fixing frame, the cleaning window is corresponding to the end face of the optical module.

[0018] Furthermore, a cleaning rod storage platform is also installed on the fixed frame. The cleaning rod storage platform is located outside the cleaning rod rotating mechanism. The cleaning rod storage platform is provided with a plurality of grooves for accommodating the cleaning rods. The plurality of grooves are distributed at intervals along the length direction of the fixed frame.

[0019] Furthermore, the feeding mechanism includes a Y-axis feeding mechanism, an X-axis picking mechanism, and a Z-axis picking mechanism. The Y-axis feeding mechanism is located in the middle of the main unit, and the X-axis picking mechanism is located on the outer side of the end of the main unit corresponding to the Y-axis feeding mechanism. A material tray is mounted on the Y-axis feeding mechanism. The X-axis picking mechanism is drivenly connected to the Z-axis picking mechanism. A picking head is mounted on the Z-axis picking mechanism, and the picking head is used to engage with the optical module.

[0020] Furthermore, a visual positioning structure is also installed on the X-axis material handling mechanism. The visual positioning structure is used to identify and calibrate the position of the optical module on the material tray. The visual positioning structure is electrically connected to the X-axis material handling mechanism to control the material handling head to adsorb the optical module according to the calibration signal of the visual positioning structure.

[0021] Furthermore, the main unit has two cleaning and detection zones symmetrically distributed about the Y-axis feeding mechanism. Each of the two cleaning and detection zones is equipped with the moving mechanism, the product fixing structure, the cleaning rod gripping structure, and the cleaning liquid injector, as well as the fixing frame, the cleaning rod rotating mechanism, the spray suction cleaning mechanism, and the end face detection structure.

[0022] Compared with existing technologies, the end-face cleaning and inspection equipment for optical modules of the present invention has the following advantages: The equipment adopts a design consisting of a main base, a loading mechanism, a moving mechanism, and a fixed frame. The loading mechanism, moving mechanism, and fixed frame are all mounted on the main base. The moving mechanism and fixed frame are arranged at intervals. The moving mechanism is equipped with a product fixing structure, a cleaning rod gripping structure, and a cleaning liquid injector. The fixed frame is equipped with a cleaning rod rotating mechanism, a spray-suction cleaning mechanism, and an end-face inspection structure. The loading mechanism can transfer the optical module to the product fixing structure, and the moving mechanism can move and switch the positions of the product fixing structure and the optical module. When the optical module is aligned with the functional modules on the fixed frame, the purpose of flexibly switching between cleaning, spraying, and inspection processes for the optical module is achieved.

[0023] The product fixing structure has a positioning part on one side of the fixing frame, the cleaning rod gripping structure has a clamp on one side of the fixing frame, and the cleaning liquid injector has an injection port on one side of the fixing frame for the cleaning rod to be inserted into the injection port to absorb the cleaning liquid. The cleaning rod rotating mechanism has a clamping head on one side of the moving mechanism, the spray suction cleaning mechanism has a spray suction head on one side of the moving mechanism, and the end face detection structure has a detection lens on one side of the moving mechanism.

[0024] A moving mechanism drives the cleaning rod gripping structure to mount the cleaning rod onto the cleaning rod rotating mechanism, and the cleaning rod is detached after rotational wiping to ensure that the cleaning rod always maintains a high level of cleanliness. Furthermore, the moving mechanism can also drive the cleaning liquid dispenser to a position aligned with the cleaning rod rotating mechanism, allowing the end of the cleaning rod to be inserted into the dispensing port of the cleaning liquid dispenser. This allows the end of the cleaning rod to absorb a small amount of cleaning liquid, improving the decontamination effect of subsequent rotational wiping.

[0025] When the positioning part of the product fixing structure moves to the alignment of the cleaning rod rotating mechanism, the clamping head drives the cleaning rod to rotate and wipe the end face of the optical module. When the positioning part of the product fixing structure moves to the alignment of the spray suction cleaning mechanism, the spray suction head sprays cleaning fluid onto the end face of the optical module and sucks up the cleaning fluid. The spray suction cleaning mechanism can effectively remove dirt and prevent dirt and cleaning fluid residue.

[0026] When the positioning part of the product fixing structure moves to the alignment end-face inspection structure, the end face of the optical module is visually inspected using an inspection lens. Furthermore, the display screen is electrically connected to the end-face inspection structure, clearly showing a magnified image of the cleaned end face of the optical module. This facilitates manual inspection to ensure the cleaned end face of the optical module meets requirements. This end-face cleaning and inspection equipment for optical modules combines cleaning and inspection functions, eliminating the need for manual transfer of optical modules for cleaning and inspection, effectively improving work efficiency and ensuring product quality.

[0027] The working process of this invention is as follows: 1. Loading: Start the loading mechanism to transfer the optical module to the positioning part of the product fixing structure and accurately fix and limit the optical module. 2. Replacing the cleaning rod: Start the moving mechanism to move the cleaning rod gripping structure to the cleaning rod rotating mechanism, use the grippers to remove the used cleaning rod, replace it with a new cleaning rod and install it into the clamping head of the cleaning rod rotating mechanism. 3. Absorbing cleaning solution: Start the moving mechanism to move the cleaning solution dispenser to the cleaning rod rotating mechanism, so that the end of the cleaning rod is inserted into the injection port to absorb the cleaning solution. 4. Rotating wiping: The moving mechanism moves the product fixing structure to the cleaning rod rotating mechanism, the end of the cleaning rod contacts the end face of the optical module and rotates to wipe it.

[0028] V. Spraying and Suctioning Cleaning Fluid: The moving mechanism moves the product fixing structure to align with the spraying and suction cleaning mechanism. The spraying and suction head sprays cleaning fluid onto the end face of the optical module and sucks up the cleaning fluid. VI. End Face Inspection: The moving mechanism moves the product fixing structure to align with the end face inspection structure. The end face of the optical module is visually inspected through the inspection lens. It should be noted that before step VI, steps 3 to 5 can be repeated to complete two or more rotational wiping and spraying and suction cleaning fluid treatments before finally performing the end face inspection process. If the inspection is qualified, the material can be unloaded. If the inspection is unqualified, steps 3 to 5 need to be repeated until the end face inspection is qualified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] like Figures 1 to 4 As shown, an end-face cleaning and testing device for an optical module according to an embodiment of the present invention includes a main unit 1, a feeding mechanism 2, a moving mechanism 3, and a fixing frame 4. The feeding mechanism 2, the moving mechanism 3, and the fixing frame 4 are all disposed on the main unit 1, and the moving mechanism 3 and the fixing frame 4 are arranged at intervals relative to each other. The moving mechanism 3 is equipped with a product fixing structure 31, a cleaning rod gripping structure 32, and a cleaning liquid injector 33. The product fixing structure 31 is provided with a positioning part 310 on one side of the fixing frame 4, the cleaning rod gripping structure 32 is provided with a gripper 320 on one side of the fixing frame 4, and the cleaning liquid injector 33 is provided with an injection port 330 on one side of the fixing frame 4, so that the cleaning rod 45 can be inserted into the injection port 330 to absorb the cleaning liquid.

[0039] The mounting frame 4 is equipped with a cleaning rod rotating mechanism 41, a spray-suction cleaning mechanism 42, and an end-face detection structure 43. The cleaning rod rotating mechanism 41 has a clamping head 410 on one side corresponding to the moving mechanism 3, which is used to detachably clamp the cleaning rod 45. The spray-suction cleaning mechanism 42 has a spray-suction head 420 on one side corresponding to the moving mechanism 3, which is used to spray cleaning fluid onto the end face of the optical module and to draw up the cleaning fluid. The end-face detection structure 43 has a detection lens 430 on one side corresponding to the moving mechanism 3, which is used to perform visual inspection on the end face of the optical module. The end-face cleaning and inspection equipment for the optical module also includes a display screen 5, which is electrically connected to the end-face detection structure 43 to display a magnified image of the end face of the optical module after cleaning.

[0040] The end-face cleaning and inspection equipment for optical modules adopts a design consisting of a main unit 1, a loading mechanism 2, a moving mechanism 3, and a fixed frame 4. The loading mechanism 2, moving mechanism 3, and fixed frame 4 are all mounted on the main unit 1. The moving mechanism 3 and fixed frame 4 are arranged at intervals. The moving mechanism 3 is equipped with a product fixing structure 31, a cleaning rod gripping structure 32, and a cleaning liquid injector 33. The fixed frame 4 is equipped with a cleaning rod rotating mechanism 41, a spray-suction cleaning mechanism 42, and an end-face inspection structure 43. The loading mechanism 2 can transfer the optical module to the product fixing structure 31. The moving mechanism 3 can move the product fixing structure 31 and the optical module to switch positions. When the optical module is aligned with the functional module on the fixed frame 4, the cleaning, spraying, and inspection processes for the optical module can be flexibly switched.

[0041] The product fixing structure 31 has a positioning part 310 on one side of the fixing frame 4, the cleaning rod gripping structure 32 has a gripper 320 on one side of the fixing frame 4, and the cleaning liquid injector 33 has an injection port 330 on one side of the fixing frame 4 for the cleaning rod 45 to be inserted into the injection port 330 to absorb the cleaning liquid. The cleaning rod rotating mechanism 41 has a clamping head 410 on one side of the moving mechanism 3, the spray suction cleaning mechanism 42 has a spray suction head 420 on one side of the moving mechanism 3, and the end face detection structure 43 has a detection lens 430 on one side of the moving mechanism 3.

[0042] The moving mechanism 3 drives the cleaning rod gripping structure 32 to mount the cleaning rod 45 onto the cleaning rod rotating mechanism 41, and removes the cleaning rod 45 after rotational wiping to ensure that the cleaning rod 45 always maintains a high level of cleanliness. Furthermore, the moving mechanism 3 can also drive the cleaning liquid injector 33 to move to a position aligned with the cleaning rod rotating mechanism 41, allowing the end of the cleaning rod 45 to be inserted into the injection port 330 of the cleaning liquid injector 33. This allows the end of the cleaning rod 45 to absorb a small amount of cleaning liquid, improving the decontamination effect of subsequent rotational wiping.

[0043] When the positioning part 310 of the product fixing structure 31 moves to the alignment of the cleaning rod rotating mechanism 41, the clamping head 410 drives the cleaning rod 45 to rotate and wipe the end face of the optical module. When the positioning part 310 of the product fixing structure 31 moves to the alignment of the spray suction cleaning mechanism 42, the spray suction head 420 sprays cleaning liquid onto the end face of the optical module and sucks up the cleaning liquid. The spray suction cleaning mechanism 42 can effectively remove dirt and prevent dirt and cleaning liquid residue.

[0044] When the positioning part 310 of the product fixing structure 31 moves to the alignment end face detection structure 43, the detection lens 430 performs visual inspection on the end face of the optical module. Furthermore, the display screen 5 is electrically connected to the end face detection structure 43, and the display screen 5 can clearly display a magnified image of the optical module's end face after cleaning, facilitating manual inspection to ensure that the cleaned end face of the optical module meets the requirements. This optical module end face cleaning and inspection equipment combines the cleaning and inspection functions of the optical module, eliminating the need for manual transfer of the optical module for cleaning and inspection, effectively improving work efficiency and ensuring the product quality of the optical module.

[0045] The working process of this invention is as follows: 1. Loading: Start the loading mechanism 2 to transfer the optical module to the positioning part 310 of the product fixing structure 31, and accurately fix and limit the optical module. 2. Replacing the cleaning rod 45: Start the moving mechanism 3 to move the cleaning rod gripping structure 32 to the cleaning rod rotating mechanism 41, and use the gripper 320 to remove the used cleaning rod 45, replace it with a new cleaning rod 45 and install it into the clamping head 410 of the cleaning rod rotating mechanism 41. 3. Absorbing cleaning solution: Start the moving mechanism 3 to move the cleaning liquid injector 33 to the cleaning rod rotating mechanism 41, so that the end of the cleaning rod 45 is inserted into the injection port 330, so that the cleaning rod 45 absorbs the cleaning solution. 4. Rotating wiping: The moving mechanism 3 moves the product fixing structure 31 to the cleaning rod rotating mechanism 41, and the end of the cleaning rod 45 contacts the end face of the optical module and rotates to wipe it.

[0046] V. Spraying and Suctioning Cleaning Fluid: The moving mechanism 3 moves the product fixing structure 31 to align with the spraying and suction cleaning mechanism 42. The spraying and suction head 420 sprays and suctions the cleaning fluid onto the end face of the optical module. VI. End Face Inspection: The moving mechanism 3 moves the product fixing structure 31 to align with the end face inspection structure 43. The end face of the optical module is visually inspected through the inspection lens 430. It should be noted that before step VI, steps 3 to 5 can be repeated to complete two or more rotational wiping and spraying and suction cleaning fluid treatments before finally performing the end face inspection process. If the inspection is qualified, the material can be unloaded. If the inspection is unqualified, steps 3 to 5 need to be repeated until the end face inspection is qualified.

[0047] In this embodiment, the product fixing structure 31 is installed on one side of the moving mechanism 3, and the positioning part 310 protrudes from the gripper 320 and the liquid injection port 330 towards the fixing frame 4; the clamping head 410, the spray suction head 420, and the detection lens 430 are respectively set at the same horizontal height corresponding to the positioning part 310. The positioning part 310 of the product fixing structure 31 protrudes from the gripper 320 and the liquid injection port 330, which can smoothly switch the optical module between different processing processes such as rotation wiping, spray suction cleaning liquid, and end face detection. Moreover, since the clamping head 410, the spray suction head 420, and the detection lens 430 are at the same horizontal height, it is only necessary to control the movement of the product fixing structure 31 in the plane, which simplifies the structural design of the moving mechanism 3.

[0048] As a further preferred embodiment, the main unit 1 has intersecting X and Y directions. The moving mechanism 3 and the fixed frame 4 are distributed relative to each other along the Y direction. The product fixing structure 31, the cleaning rod gripping structure 32, and the cleaning liquid injector 33 are arranged along the X direction on the moving mechanism 3. The cleaning rod rotating mechanism 41, the spray suction cleaning mechanism 42, and the end face detection structure 43 are arranged along the X direction on the fixed frame 4. Specifically, the moving mechanism 3 includes an X-direction moving mechanism 34 and a Y-direction moving mechanism 35. The X-direction moving mechanism 34 is arranged parallel to the length direction of the fixed frame 4 and is used to drive the product fixing structure 31, the cleaning rod gripping structure 32, and the cleaning liquid injector 33 to switch positions along the X direction. Moreover, the Y-direction moving mechanism 35 is arranged parallel to the width direction of the fixed frame 4 and is used to drive the product fixing structure 31, the cleaning rod gripping structure 32, and the cleaning liquid injector 33 to move closer to or further away from the fixed frame 4 along the Y direction.

[0049] The positioning part 310 of the product fixing structure 31 is a positioning groove. An opening is provided on one side of the fixing frame 4 corresponding to the positioning groove. A limiting member 311 is installed at the opening of the positioning groove. The limiting member 311 is used for press-fitting with the end face of the optical module. Figure 3 As shown, the opening direction of the positioning groove is parallel to the width direction of the fixing frame 4. The limiting member 311 is an L-shaped limiting member, which is movably assembled at the opening of the positioning groove. A cleaning window 312 is provided on the side of the fixing frame 4 corresponding to the L-shaped limiting member, and the cleaning window 312 corresponds to the end face of the optical module. The L-shaped limiting member can not only clamp and position the optical module, but also fully expose the end face of the optical module through the cleaning window 312, so as to avoid interference with the cleaning and testing processes.

[0050] Furthermore, a cleaning rod storage platform 44 is also installed on the mounting frame 4. The cleaning rod storage platform 44 is located outside the cleaning rod rotating mechanism 41. The cleaning rod storage platform 44 is provided with multiple grooves 440 for accommodating cleaning rods 45, and the multiple grooves 440 are distributed at intervals along the length of the mounting frame 4. It should be noted that a Z-axis drive structure (not shown in the figure) is also provided between the cleaning rod storage platform 44 and the mounting frame 4. Under normal circumstances, the cleaning rod storage platform 44 is positioned below the cleaning rod rotating mechanism 41 to prevent the cleaning rod storage platform 44 from interfering with the translational movement of other components. When a new cleaning rod 45 needs to be replaced, the cleaning rod storage platform 44 moves upward so that the cleaning rod gripping structure 32 can accurately grip the cleaning rod 45, and after gripping, the cleaning rod storage platform 44 automatically descends to reset.

[0051] In this embodiment, the feeding mechanism 2 includes a Y-axis feeding mechanism 21, an X-axis picking mechanism 22, and a Z-axis picking mechanism 23. The Y-axis feeding mechanism 21 is located in the middle of the main unit 1, and the X-axis picking mechanism 22 is located on the outer side of the end of the main unit 1 corresponding to the Y-axis feeding mechanism 21. A material tray 24 is installed on the Y-axis feeding mechanism 21. The X-axis picking mechanism is connected to the Z-axis picking mechanism 23. A picking head 25 is installed on the Z-axis picking mechanism 23. The picking head 25 is used to cooperate with the optical module for adsorption.

[0052] Furthermore, a vision positioning structure 26 is installed on the X-axis material handling mechanism 22. The vision positioning structure 26 is used to identify and calibrate the position of the optical module on the material tray 24. The vision positioning structure 26 is electrically connected to the X-axis material handling mechanism 22 to control the material handling head 25 to pick up the optical module according to the calibration signal of the vision positioning structure 26. The Y-axis feeding mechanism 21 first moves the material tray 24 to the lower side of the vision positioning structure 26. The vision positioning structure 26 identifies and calibrates the position of the optical module on the material tray 24. The X-axis material handling mechanism 22 controls the material handling head 25 to move to the calibrated position, and the Z-axis material handling mechanism 23 drives the material handling head 25 to pick up the optical module downward. After picking up, it drives the optical module to move upward and places the optical module in the positioning part 310 of the product fixing structure 31 through the X-axis material handling mechanism 22, thus completing the automatic feeding and picking process.

[0053] In addition, the main unit 1 has two cleaning and inspection areas 10 symmetrically distributed about the Y-axis feeding mechanism 21. Each cleaning and inspection area 10 is equipped with a moving mechanism 3, a product fixing structure 31, a cleaning rod gripping structure 32, and a cleaning liquid injector 33, as well as a fixing frame 4, a cleaning rod rotating mechanism 41, a spray-suction cleaning mechanism 42, and an end-face inspection structure 43. That is, two sets of moving mechanisms 3, product fixing structures 31, cleaning rod gripping structures 32, cleaning liquid injectors 33, fixing frames 4, cleaning rod rotating mechanisms 41, spray-suction cleaning mechanisms 42, and end-face inspection structures 43 are symmetrically arranged on both sides of the main unit 1 corresponding to the Y-axis feeding mechanism 21. Using a single feeding mechanism 2, the optical modules are fed sequentially to the two cleaning and inspection areas 10. The two cleaning and inspection systems can independently complete the end-face cleaning and inspection of the optical modules, further improving work efficiency.

[0054] It should be noted that the end-face cleaning and testing equipment for this optical module also includes an outer casing, a touch screen 6, and an air filter 7, such as... Figure 4As shown, the outer casing is installed outside the main unit base 1, enclosing all working components in a closed environment. The touchscreen 6 and air filter 7 are both mounted on the outer casing. The touchscreen 6 is electrically connected to the feeding mechanism 2, moving mechanism 3, product fixing structure 31, cleaning rod gripping structure 32, cleaning liquid injector 33, fixing frame 4, cleaning rod rotating mechanism 41, spray suction cleaning mechanism 42, and end face detection structure 43, respectively, for human-machine interaction, controlling the movement of each working module, and parameter adjustment. The air filter 7 filters external air to ensure that the air entering the outer casing remains clean. In addition, the outer casing is equipped with an emergency stop button, pause button, reset button, start button, and a keyboard and mouse, allowing manual control of the equipment's operating status.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
