[0049] Figure 3 Here is a structural diagram of an optical module according to some embodiments, such as Figure 3 As shown, in some embodiments, the optical module 200 includes a shell, which includes an upper shell 201 and a lower shell 202. The upper shell 201 covers the lower shell 202, forming two openings, one of which is an electrical port 204, and the other is an optical port 205. In some embodiments, the shell forms an opening that serves as both an electrical port and an optical port.

[0060] In some embodiments, the optical module end face detection and cleaning device may include a barcode scanning component. The cleaning component 5 is communicatively connected to the barcode scanning component. The cleaning component 5 can mark the cleanliness corresponding to the optical module code so that the loading and unloading component 2 can classify and place the cleaned optical modules.

[0061] For example, optical modules that meet the cleanliness standard are marked with the first mark, and optical modules that do not meet the cleanliness standard are marked with the second mark.

[0062] In some embodiments, optical modules that meet the cleanliness standard are marked as 0, and optical modules that do not meet the cleanliness standard are marked as 1 or the opposite, or other marking values ​​are used.

For optical modules that pass the first detection, no further detection or cleaning is performed when they enter the cleaning component 5 and the second detection component station. For optical modules that fail the first detection, cleaning and secondary detection are performed when they enter the cleaning component 5 and the second detection component station.

[0066] Figure 5 This is a schematic diagram of a relay device according to some embodiments. For ease of description, Figure 5 In the diagram, X represents the front-to-back direction, Y represents the up-down direction, and Z represents the left-to-right direction. For example... Figure 5 As shown, the transfer device 3 provided in this disclosure includes: a rotating component 600 and at least one clamping component 700 and an unlocking component 800 disposed on the rotating component 600.

[0067] At least one means one or more, such as two groups, three groups, four groups or more.

[0068] The optical module 200 can be clamped within the clamping assembly. The rotating assembly 600 drives the clamping assembly 700 to rotate, aligning the clamping assembly 700 with the unlocking assembly 800. The unlocking assembly 800 rises upwards, driving the clamping assembly 700 to release the optical module 200. The rotating assembly 600 is driven by a motor, ensuring precise clamping and unlocking actions. The clamping assembly 700 is equipped with an elastic element to provide stable clamping force. The unlocking assembly 800 employs a mechanical linkage design, simplifying the operation process and improving efficiency. The overall mechanism is compact, suitable for various optical module specifications, ensuring convenient installation and maintenance.

[0069] Figure 6 This is a schematic diagram of a rotating assembly according to some embodiments. Figure 6 As shown, the rotating assembly 600 includes a fixed platform 610, and a rotating shaft 620 is fixed to the fixed platform 610. A mounting platform 630 is provided above the rotating shaft 620, which is used to fix the clamping assembly 700. The rotating shaft 620 rotates in the XZ plane to change the position of the clamping assembly 700 in the XZ direction.

[0070] The mounting platform 630 is provided with one or more mounting clearance positions 631, and the clamping assembly 700 is mounted at the mounting clearance position 631. The clamping assembly 700 can be fixedly connected to the mounting platform 630 via a connector. During the rotation of the shaft 620, the mounting platform 630 carries the clamping assembly 700 to move the optical module 200 to the position of the next procedure. The design of the mounting clearance position 631 ensures that the clamping assembly 700 is free from interference during rotation, improving the smoothness of operation. The precision bearing support of the shaft 620 reduces friction and extends service life. The rotation angle of the shaft 620 is adjusted by the control system to ensure precise docking between the clamping assembly 700 and the unlocking assembly 800.

[0071] In some embodiments, the fixing stage 610 is located below the rotating shaft 620. The fixing stage 610 is provided with an unlocking clearance portion 640. The unlocking component 800 is located in the unlocking clearance portion 640 and is connected to the fixing stage 610. The unlocking component 800 and the unlocking clearance portion 640 are positioned correspondingly. When the unlocking component 800 is raised upward, it interferes with the clamping component 700, and the clamping component 700 is in an unlocked state, not clamping the optical module, facilitating the transfer of the optical module. When the unlocking component 800 moves downward, it separates from the unlocking clearance portion 640, and the clamping component 700 is in a clamping state, locking the optical module.

For example... Figure 7 , Figure 8As shown, the clamping assembly 700 includes a clamping platform 710, which provides a support platform for the optical module 200.

[0073] In some embodiments, the clamping assembly 700 includes a limiting protrusion 711 located above the clamping platform 710, the limiting protrusion 711 protruding upward to provide positional limitation for the optical module 200.

[0074] In some embodiments, the clamping assembly 700 includes a first clamping device 720. The first clamping device 720 clamps the optical module 200 in the up-down (Y) direction and provides positioning in the up-down direction.

[0075] In some embodiments, the clamping assembly 700 includes a second clamping device 730. The second clamping device 730 clamps the optical module 200 in the front-to-back (X) direction, providing front-to-back positioning.

[0076] In some embodiments, the clamping assembly 700 includes a third clamping device 740. The third clamping device 740 clamps the optical module 200 in the left-right direction (Z) and provides left-right positioning.

[0077] In some embodiments, the clamping platform 710 is provided with a first through hole 712, through which a first clamping device 720 passes, such that a portion of the first clamping device 720 is positioned above the clamping platform 710, thus defining the optical module 200. Another portion of the first clamping device 720 is positioned below the clamping platform 710. When the unlocking component 800 is raised, it can exert an upward force on the first clamping device 720, causing the first clamping device 720 to separate from the optical module 200, thereby releasing the first clamping device 720 from defining the optical module 200 in the vertical direction.

[0078] In some embodiments, the first clamping device 720 rotates during the upward lifting process, so that the first clamping device 720 is removed from the range of the optical module 200, thereby separating the first clamping device 720 from the optical module 200 and releasing the first clamping device 720 from restricting the optical module 200 in the vertical direction.

[0079] In some embodiments, the clamping platform 710 is provided with a second through hole 713, through which a second clamping device 730 passes, such that a portion of the second clamping device 730 is positioned above the clamping platform 710, thus defining the optical module 200. Another portion of the second clamping device 730 is positioned below the clamping platform 710. When the unlocking component 800 is raised, it can generate a forward-backward force (forward, i.e., the positive X direction) on the second clamping device 730, causing the second clamping device 730 to separate from the optical module 200, thereby releasing the constraint of the second clamping device 730 on the optical module 200 in the forward-backward direction.

[0080] In some embodiments, the clamping platform 710 is provided with a third through hole 714, through which a third clamping device 740 passes, such that a portion of the third clamping device 740 is positioned above the clamping platform 710, thus constraining the optical module 200. Another portion of the third clamping device 740 is positioned below the clamping platform 710. When the unlocking component 800 is raised, it can generate a lateral force (to the left, i.e., the positive Z direction) on the third clamping device 740, causing the third clamping device 740 to separate from the optical module 200, thereby releasing the lateral constraint of the third clamping device 740 on the optical module 200.

[0081] The clamping and unlocking of the first clamping device 720, the second clamping device 730, and the third clamping device 740 can be achieved by lifting the unlocking component 800, thereby achieving clamping and unlocking of the optical module in three dimensions.

[0082] In some embodiments, the clamping platform 710 is provided with a left limiting arm 715, which protrudes from the upper surface of the clamping platform 710. The left limiting arm 715 is in contact with the optical module 200, and limits the left and right positions of the optical module 200. For example, the left limiting arm 715 is located on the left side of the optical module 200, and its right side wall is in contact with the optical module 200, limiting the left side of the optical module 200. The left limiting arm 715 is located on the opposite side of the third clamping device 740, and cooperates with the third clamping device 740 to limit the left and right directions of the optical module 200.

[0083] Figure 9 This is a schematic diagram of the structure of an unlocking component according to some embodiments. Figure 10 This is a schematic diagram of a clamping platform according to some embodiments. Figure 9 , Figure 10 As shown, the unlocking component 800 includes an unlocking fixing member 810 and an unlocking slide member 820, the unlocking slide member 820 being slidable relative to the unlocking fixing member 810 in the vertical direction. In some embodiments, the unlocking fixing member 810 may be fixedly connected to the fixing platform 610.

[0084] The unlocking slider 820 is connected to the unlocking fixing component 810 via a sliding groove to ensure smooth sliding. When the unlocking slider 820 slides upward, it pushes the unlocking component 800 to rise, thereby unlocking the first clamping device 720, the second clamping device 730, and the third clamping device 740, enabling the optical module 200 to move freely in three dimensions.

[0085] The unlocking assembly 800 may include a power unit (not shown) that drives the unlocking slider 820 to move up and down. The unlocking slider 820 includes a first unlocking member 830, which corresponds to the position of the first clamping device 720. When the unlocking slider 820 is lifted upward, the first unlocking member 830 contacts the first clamping device 720 and exerts an upward force on the first clamping device 720, causing the first clamping device 720 to be lifted upward and separated from the optical module 200.

[0086] The unlocking slider 820 includes a second unlocking member 840, which corresponds to the position of the second clamping device 730. When the unlocking slider 820 is lifted upward, the second unlocking member 840 contacts the second clamping device 730, and the second unlocking member 840 moves along the second clamping device 730, exerting a forward force on the second clamping device 730, causing the first clamping device 720 to move forward. The second clamping device 730 separates from the optical module 200, releasing the second clamping device 730 from restricting the optical module 200.

[0087] A second elastic component 7131 is located below the clamping platform 710, and is situated on one side of the second clamping device 730. The second elastic component 7131 is in contact with the second clamping device 730, and a second unlocking member 840 is located in front of the second clamping device 730. When the unlocking component 800 is lifted upwards, the second unlocking member 840 is also lifted upwards, compressing the second clamping device 730 and causing it to move forward, thus compressing the second elastic component 7131. When the unlocking component 800 moves downwards, the second unlocking member 840 separates from the second clamping device 730. Under the stretching force of the second elastic component 7131, the second clamping device 730 moves backwards, reducing the distance between the second clamping device 730 and the rear limiting arm, thus clamping the optical module 200.

[0088] The second elastic component 7131 can extend and retract under force, allowing the distance between the second clamping device 730 and the rear limiting arm to change according to the actual size of the optical module 200, thus improving the adaptability of the transfer device. For example, the second elastic component 7131 can extend and retract under force, allowing the distance between the second clamping device 730 and the rear limiting arm to change according to the front-rear dimensions of the optical module 200, thus improving the adaptability of the transfer device.

[0089] The unlocking slider 820 includes a third unlocking member 850, which corresponds to the position of the third clamping device 740. When the unlocking slider 820 is lifted upward, the third unlocking member 850 contacts the third clamping device 740, and the third unlocking member 850 moves upward along the third clamping device 740, exerting a rightward force on the third clamping device 740, causing the third clamping device 740 to move to the right, separating the third clamping device 740 from the optical module 200, and releasing the third clamping device 740 from the optical module 200.

[0090] A third elastic component 7141 is located below the clamping platform 710, on one side of the third clamping device 740. The third elastic component 7141 is in contact with the third clamping device 740, and the third unlocking component 850 is located to the left of the third clamping device 740. When the unlocking component 800 is lifted upwards, the third unlocking component 850 is also lifted upwards, compressing the second clamping device 730 and causing the third clamping device 740 to move to the right, thus compressing the third elastic component 7141. When the unlocking component 800 moves downwards, the third unlocking component 850 separates from the third clamping device 740. Under the stretching force of the third elastic component 7141, the third clamping device 740 moves to the left, reducing the distance between the third clamping device 740 and the left limiting arm 715, thus clamping the optical module 200.

[0091] The third elastic component 7141 can extend and retract under force, allowing the distance between the third clamping device 740 and the left limiting arm 715 to change according to the actual size of the optical module 200, thus improving the adaptability of the transfer device. For example, the third elastic component 7141 can extend and retract under force, allowing the distance between the third clamping device 740 and the limiting arm 715 to change according to the left-right dimensions of the optical module 200, thus improving the adaptability of the transfer device.

[0092] Figure 11 This is a schematic diagram of the structure of a first clamping device according to some embodiments. Figure 12 This is an exploded structural diagram of a first clamping device according to some embodiments. Figure 11 and Figure 12 As shown, the first clamping device 720 includes a fixing base 7201. The fixing base 7201 is fixedly connected to the clamping platform 710, thereby fixing the first clamping device 720 onto the clamping platform 710.

[0093] The first clamping device 720 includes a connecting rod 7202. The connecting rod 7202 is movably connected to the fixed base 7201. The connecting rod 7202 is located at the first through hole 712 so that the connecting rod 7202 can pass through the first through hole 712. One end of the connecting rod 7202 is located below the clamping platform 710, and the other end of the connecting rod 7202 is located above the clamping platform 710.

[0094] The first clamping device 720 includes a clamping part 7204. The clamping part 7204 is connected to the connecting rod 7202. When the clamping assembly 700 clamps the optical module 200, the clamping part 7204 is located above the optical module 200. One end of the connecting rod 7202 passes through the fixing base 7201 and is connected to the clamping part 7204, and the other end corresponds to the position of the first unlocking member 830.

[0095] The clamping part 7204 may also be provided with a buffer pad 7205. The hardness of the buffer pad 7205 is less than that of the clamping part 7204. The buffer pad 7205 is located between the optical module 200 and the clamping part 7204 to reduce damage to the optical module 200.

[0096] The first unlocking member 830 is located below the connecting rod 7202. When the first unlocking member 830 is lifted upward, it contacts the connecting rod 7202 and exerts an upward force on the connecting rod 7202, causing the connecting rod 7202 and the clamping part 7204 to lift upward.

[0097] In some embodiments, the first clamping device 720 includes a slider fixing member 7203. A groove 7206 is provided on the connecting rod 7202. One end of the slider fixing member 7203 is fixed to the clamping platform 710, and the other end of the slider fixing member 7203 is disposed in the groove 7206. The groove 7206 extends around the upper left of the connecting rod 7202. When the first unlocking member 830 is lifted upward, the connecting rod 7202 moves upward, and the slider fixing member 7203 slides in the groove 7206, so that the connecting rod 7202 and the clamping part 7204 rotate to the left, and the clamping part 7204 separates from the optical module 200.

[0098] The connecting rod 7202 has a columnar structure, and the sliding groove 7206 is spirally wound around the connecting rod 7202. The slider fixing part 7203 slides more smoothly in the sliding groove 7206, reducing the friction between the sliding groove 7206 and the slider fixing part 7203.

[0099] When the first unlocking member 830 is lifted upward, it contacts the connecting rod 7202 and exerts an upward force on it. The slider fixing member 7203 slides within the slide groove 7206, causing the connecting rod 7202 and the clamping part 7204 to rotate to the left while moving upward, thus separating the clamping part 7204 from the optical module 200. Furthermore, the clamping part 7204 is not positioned above the optical module; the external clamping device can clamp the optical module 200 and move it upward to separate it from the clamping assembly 700.

[0100] In some embodiments, the first clamping device 720 includes a first elastic element 7207, which is sleeved on the outside of the connecting rod 7202. When the first clamping device 720 is in the unlocked state, the first elastic element 7207 is in the compressed state. The first elastic element 7207 can be used to buffer the impact force of the first unlocking member 830 on the connecting rod 7202. When the first unlocking member 830 descends downward, the first unlocking member 830 separates from the connecting rod 7202. Under the elastic action of the first elastic element 7207, the connecting rod 7202 descends downward, while the slider fixing member 7203 slides in the slide groove 7206, so that the connecting rod 7202 and the pressing part 7204 rotate to the right while moving downward. The pressing part 7204 presses against the optical module 200, clamping the upper part of the optical module 200.

[0101] Figure 13 This is a schematic diagram of a second clamping device according to some embodiments. Figure 13 As shown, the second clamping device 730 includes a first slide rail retainer 7301 and a first slide rail 7302, the first slide rail 7302 being movable along the first slide rail retainer 7301. The first slide rail retainer 7301 is fixed to the clamping platform 710, and the first slide rail 7302 is movable back and forth along the first slide rail retainer 7301 to realize the telescopic function of the second clamping device 730. When the first slide rail 7302 moves forward, the second clamping device 730 applies pressure to the optical module 200, ensuring that the optical module 200 is tightly fitted with the clamping platform 710. Conversely, when the first slide rail 7302 moves backward, the pressure is released, facilitating the disassembly and replacement of the optical module 200.

[0102] The first slide rail 7302 has a first stop arm 7303 at its end. The first stop arm 7303 can pass through the second through hole 713. A part of the first stop arm 7303 is located above the clamping platform 710, which restricts the optical module 200. The other part of the first stop arm 7303 is located below the clamping platform 710. When the unlocking component 800 is raised, it can generate a forward force on the first stop arm 7303 (forward, that is, the positive X direction), so that the first stop arm 7303 is separated from the optical module 200, thereby releasing the restriction of the optical module 200 by the second clamping device 730 in the front-back direction.

[0103] The position of the second unlocking member 840 corresponds to the position of the first stop arm 7303. When the unlocking slide 820 is lifted upward, the second unlocking member 840 exerts a forward force on the first stop arm 7303, causing the first stop arm 7303 to move forward and separate from the optical module 200, thus releasing the second clamping device 730 from restricting the optical module 200 in the front-back direction.

[0104] In some embodiments, the second unlocking member 840 includes a first roller that can roll along the first stop arm 7303. The side of the first stop arm 7303 that contacts the second unlocking member 840 is a first inclined surface 7304. The first inclined surface 7304 causes the thickness of the first stop arm 7303 to gradually increase from bottom to top, so that when the second unlocking member 840 is lifted upward, the first stop arm 7303 gradually moves forward, improving the stability of the unlocking member. When the second unlocking member 840 is lifted upward, the first stop arm 7303 gradually moves forward, and the first stop arm 7303 compresses the second elastic component 7131. When the second unlocking member 840 moves downward, the second unlocking member 840 separates from the first stop arm 7303, and the second elastic component 7131 extends to push the first stop arm 7303 to move backward, reducing the distance between the first stop arm 7303 and the rear limiting arm 716, thus clamping the optical module 200 in the front-rear direction.

[0105] In some embodiments, the second elastic component 7131 includes a second elastic member and an elastic fixing member, with the second elastic member disposed between the elastic fixing member and the first stop arm. After the second unlocking member 840 separates from the first stop arm 7303, the second elastic member returns to its original length, pushing the first stop arm 7303 to move rearward, reducing the distance between the first stop arm 7303 and the rear limiting arm 716, thus clamping the optical module 200 in the front-rear direction. In some embodiments, the first stop arm 7303 is provided with a front clearance portion 7305, which is located above the clamping platform 710 for clearance by external grippers.

[0106] In some embodiments, the second elastic element may be a helical spring or a leaf spring, whose elastic restoring force ensures that the first stop arm 7303 is stably reset, thereby enhancing the clamping reliability.

[0107] Figure 14 This is a schematic diagram of a third clamping device according to some embodiments. Figure 14 As shown, the third clamping device 740 includes a second slide rail retainer 7401 and a second slide rail 7402, the second slide rail 7402 being movable along the second slide rail retainer 7401. The second slide rail retainer 7401 is fixed to the clamping platform 710, and the second slide rail 7402 is movable left and right along the second slide rail retainer 7401.

[0108] The end of the second slide rail 7402 is provided with a second stop arm 7403, which can pass through the second through hole 713. A part of the second stop arm 7403 is located above the clamping platform 710, limiting the optical module 200. The other part of the second stop arm 7403 is located below the clamping platform 710. When the unlocking component 800 is raised, it can generate a force to the right (to the right, that is, the positive Z direction) on the second stop arm 7403, so that the second stop arm 7403 is separated from the optical module 200, thereby releasing the limitation of the third clamping device 740 on the optical module 200 in the left and right direction.

[0109] The position of the third unlocking member 850 corresponds to the position of the second stop arm 7403. When the unlocking slide 820 is lifted upward, the third unlocking member 850 exerts a forward force on the second stop arm 7403, causing the second stop arm 7403 to move forward and separate from the optical module 200, thus releasing the restriction of the optical module 200 in the left and right directions by the third clamping device 740.

[0110] In some embodiments, the third unlocking member 850 includes a second roller that can roll along the second stop arm 7403. The side of the second stop arm 7403 that contacts the third unlocking member 850 is a second inclined surface 7404. The second inclined surface 7404 causes the thickness of the second stop arm 7403 to gradually increase from bottom to top, so that when the third unlocking member 850 is lifted upward, the second stop arm 7403 gradually moves to the right. When the third unlocking member 850 is lifted upward, the second stop arm 7403 gradually moves to the right, and the second stop arm 7403 compresses the third elastic component 7141. The third unlocking member 850 moves downward, separating from the second stop arm 7403, and the third elastic component 7141 extends to push the second stop arm 7403 to the left, reducing the distance between the second stop arm 7403 and the left limiting arm 715, thus clamping the optical module 200 in the left-right direction.

[0111] In the above embodiments, when the unlocking component 800 is raised upwards, the unlocking component interferes with the clamping component, and the first clamping device 720, the second clamping device 730, and the third clamping device 740 are in an unlocked state. When the unlocking component 800 is lowered downwards, the unlocking component separates from the clamping component, and the first clamping device 720, the second clamping device 730, and the third clamping device 740 return to the clamping state under the action of the elastic element, clamping the optical module 200 in three different directions. The elastic element configuration of the first clamping device 720, the second clamping device 730, and the third clamping device 740 allows the optical module clamping and unlocking mechanism to adapt to optical modules of different sizes, improving the versatility of the optical module clamping and unlocking mechanism.

[0112] In the embodiments of this disclosure, only one power unit is provided in the unlocking component 800 to provide upward and downward force to the unlocking component. Under the action of the first unlocker, the second unlocker, and the third unlocker, the first clamping device 720, the second clamping device 730, and the third clamping device 740 are unlocked, and the optical module 200 is unlocked from three different directions. This avoids the need for multiple pipes when using power units in different directions simultaneously, reduces space occupancy, and reduces the entanglement of pipes during the driving process between different power units.

[0113] The power unit is located on the unlocking component 800 and is separate from the clamping component 700. When the clamping component 700 is rotated or otherwise operated, it will not interfere with the pipes on the unlocking component 800, which helps to improve the stability of the structure.

[0114] In some embodiments of this disclosure, one unlocking component 800 may correspond to multiple clamping components 700, and the rotating component 600 rotates to make the unlocking component 800 correspond to different clamping components 700. A power component is provided only in the unlocking component 800, avoiding the provision of pipes on the rotating component 600 and clamping components 700, thus preventing pipe entanglement during rotation.

[0115] Figure 15 This is a schematic diagram of a cleaning assembly according to some embodiments. Figure 15 As shown, in some embodiments of this disclosure, the cleaning component 5 may include a moving module 51. The moving module 51 is movable along a first direction and a second direction.

[0116] The cleaning component 5 may include a cleaning component holder 52. The cleaning component holder 52 is fixed to the moving module 51, which can move the cleaning component holder 52 along a first direction and a second direction, so that the cleaning component on the cleaning component holder 52 corresponds to the port of the optical module. The cleaning component holder 52 can quickly replace different types of cleaning components to adapt to various optical module port specifications. The moving module 51, through a precision guide rail and drive motor, achieves micron-level positioning accuracy, ensuring that the cleaning component is accurately aligned with the port. Upon receiving a cleaning command, the control system drives the moving module 51 to deliver the cleaning component to the designated position, automatically completing the wiping action. The entire process requires no manual intervention, improving cleaning efficiency and consistency.

[0117] In some embodiments, the moving module 51 may include a first mover 511 to allow the cleaning component holder 52 to move along a first direction. In some embodiments, the moving module 51 may include a second mover 512 to allow the cleaning component holder 52 to move along a second direction. The second mover 512 may move with the first mover, that is, the second mover 512 moves along the moving direction of the first mover 511.

[0118] In some embodiments, the mobile module 51 may include a connector 513, which is fixed to the second locator 512 and moves with the second locator 512.

[0119] In some embodiments, the cleaning component holder 52 is fixed to the connecting seat 513 so that the cleaning component holder 52 moves with the moving module 51 to achieve correspondence between the holder 52 and the optical module to be cleaned. The cleaning component holder 52 is fixed on the connecting seat 513 and moves synchronously with the movement of the second mover 512 in the second direction, thereby achieving precise positioning in a two-dimensional plane. When the first mover 511 is driven along the first direction, it drives the second mover 512 and the connecting seat 513 to move as a whole, thereby adjusting the cleaning component holder 52 to the target row position; then the second mover 512 makes fine adjustments along the second direction in a local range to complete the column-direction positioning.

[0120] Figure 16 This is a structural schematic diagram of a cleaning component holder according to some embodiments. Figure 17 This is a cross-sectional structural schematic diagram of a cleaning component holder according to some embodiments. Figure 18 This is an exploded structural diagram of a cleaning component holder according to some embodiments. (Combined with...) Figure 16 , Figure 17 and Figure 18 As shown, the cleaning part holder 52 includes a fixing part 521, which is fixedly connected to the connecting seat 513 so that the cleaning part holder 52 moves with the moving module 51.

[0121] In some embodiments, the cleaning component holder 52 includes a rotation drive component 523 for driving the cleaning component to rotate. The rotation drive component 523 is connected to the cleaning component and can drive the cleaning component to rotate during the cleaning process, thereby improving the wiping coverage of the inner wall of the optical module port. This rotation action is coordinated with the two-dimensional translation control of the moving module 51 to achieve precise cleaning with multiple degrees of freedom.

[0122] In some embodiments, the rotary drive component 523 includes a rotary motor 5231 and a rotary connector 5232. The rotary connector 5232 is connected to the shaft of the rotary motor 5231, and the rotary connector 5232 is rotatably connected to the rotary motor 5231. The rotary connector 5232 can rotate with the shaft of the rotary motor 5231. One end of the rotary connector 5232 away from the rotary motor 5231 is used to connect to a cleaning component to transmit the driving force of the rotary motor to the cleaning component.

[0123] The rotary motor mimics the manual wiping method, achieving free-angle, uniform rotation to ensure even force distribution when the cleaning component contacts the optical module port, effectively removing contaminants. The rotary connector transmits motor torque to the cleaning component, achieving stable transmission. The cleaning component holder can also be equipped with a position sensor to monitor the insertion depth and rotation angle of the cleaning component in real time, improving cleaning accuracy.

[0124] In some embodiments, the rotary connector 5232 includes a coupling 52321. The coupling 52321 effectively transmits the torque of the rotary motor 5131 while compensating for any axial deviations that may occur during rotation, ensuring stable rotation of the cleaning component. The rotary drive component allows for uniform wiping of the cleaning component upon contact with the optical module port, improving cleaning effectiveness. The robust connection between the fixing part and the connecting seat, combined with the multi-directional moving module, enables the cleaning component holder to be precisely positioned to the target port location. The overall structure is compact, with precise motion control, suitable for automated cleaning scenarios of high-density optical module arrays, effectively improving maintenance efficiency and connection reliability.

[0125] In some embodiments, the rotary connector 5232 includes a connecting retainer 52322. The connecting retainer 52322 is fixedly connected to the connecting seat 513 to stably support the rotary motor 5231 and reduce vibration transmission. The connecting retainer 52322 achieves a detachable connection with the connecting seat 513 through a threaded engagement or snap-fit ​​structure, facilitating maintenance and replacement. The rotary motor 5231 is securely mounted on the fixing part 521 via the connecting retainer 52322, ensuring coaxiality and smooth operation during rotary drive.

[0126] The rotary drive component works in conjunction with the multi-directional moving module, enabling the cleaning component to flexibly adjust its posture in three-dimensional space to adapt to the cleaning requirements of different optical module ports. The elastic compensation mechanism of the 52321 coupling effectively reduces the impact of mechanical vibration on the cleaning process, avoiding damage to the end-face plating. Through precise adjustment of the rotation speed and movement path by the control system, the cleaning component can complete rotation, reciprocating, and positioning actions according to a preset program, achieving thorough wiping.

[0127] In some embodiments, the rotary connector 5232 includes a connecting shaft 5233. The connecting shaft 5233 is fixedly connected to the coupling 51321 and is used to transmit the torque of the rotary motor 5131 and drive the cleaning components to rotate synchronously.

[0128] In some embodiments, one end of the connecting shaft 5233 is equipped with a snap-fit ​​structure, which allows for quick installation or removal of the cleaning component, facilitating the replacement of cleaning heads of different specifications to adapt to various port types. This structure is supported by precision bearings, ensuring high coaxiality and smooth operation during rotation. Under the command of the control system, the rotation speed can be dynamically adjusted according to the cleaning material and degree of contamination, avoiding damage caused by excessive friction. The entire drive chain is responsive and precise in positioning, and combined with the multi-degree-of-freedom motion capability of the moving module, it achieves efficient and safe cleaning of the optical module ports, suitable for industrial applications requiring long-term continuous operation.

[0129] In some embodiments, the cleaning component holder 52 is provided with a clamping member 524 for firmly gripping the cleaning component and preventing it from loosening or shifting during high-speed rotation or reciprocating motion. The clamping member 524 is connected to the connecting shaft 52323, and the clamping member 524 can rotate with the rotation of the connecting shaft 5233, thereby driving the cleaning component to complete the rotation cleaning action synchronously.

[0130] In some embodiments, the clamping component 524 includes a chuck 5241. The chuck 5241 achieves adaptive coverage of the cleaning component through an elastic clamping structure, ensuring uniform distribution of clamping force and preventing localized stress damage to the surface of the cleaning head. The inner wall of the chuck 5241 is provided with anti-slip textures or a wear-resistant coating to enhance anti-slip performance and prevent relative slippage during high-speed rotation. The elastic clamping structure of the chuck 5241, through a preload and deformation compensation mechanism, maintains a stable clamping effect when cleaning components of different diameters are installed, improving adaptability and reliability.

[0131] The cleaning component is interference-fitted with the chuck 5241, which enables quick clamping and secure fixation, ensuring that no axial movement or radial displacement occurs during rotation.

[0132] In some embodiments, the inner diameter of the chuck 5241 is smaller than the diameter of the clamping area of ​​the cleaning component, achieving a tight connection through an interference fit, effectively transmitting torque and preventing slippage. The chuck 5241 adapts to the installation and removal of the cleaning component within its elastic deformation range, providing high repeatability and ensuring consistency in each clamping operation. The interference fit design also enhances connection rigidity, suppresses high-frequency vibration transmission, and further guarantees the stability of the cleaning process.

[0133] The chuck 5241 employs an elastic clamping structure, which provides a constant clamping force through springs or deformable materials to ensure that the cleaning components remain firmly connected during dynamic operation.

[0134] In some embodiments, the clamping component 524 includes a connecting rod 5242, one end of which is fixedly connected to the chuck 5241. The connecting rod 5242 is in a transmission engagement with the connecting shaft 5233 to transmit rotational power and maintain the overall rigidity of the clamping structure.

[0135] In some embodiments, the connecting rod 5242 and the clamp 5241 can be integrally formed to improve structural strength and concentricity accuracy and reduce vibration during high-speed rotation.

[0136] In some embodiments, the connecting rod 5242 and the connecting shaft 5233 are coupled through a spline or flat-position transmission structure to ensure efficient torque transmission while allowing slight axial floating, thus avoiding stress concentration caused by assembly errors.

[0137] In some embodiments, a low-friction sliding fit is achieved between the connecting shaft 5233 and the connecting rod 5242 via a ball bearing structure, ensuring smooth rotation and effectively absorbing radial runout errors, thereby improving overall operational stability. The balls are distributed within an annular track, and the pre-compression design eliminates gaps, ensuring zero backlash in power transmission. This structure performs excellently under high-speed start-stop and variable frequency operation conditions, significantly reducing wear rates and extending component lifespan.

[0138] In some embodiments, the other end of the connecting rod 5242 is provided with an elastic element 5243. The elastic element 5243 is sleeved on the outer periphery of the positioning post 5244, with one end abutting against the coupling 52321 and the other end abutting against the positioning post 5244 structure, forming an axial preload to compensate for assembly gaps and absorb minor displacements during operation. When the cleaning part and the chuck experience axial impact, the elastic element can buffer vibration energy, reduce reverse impact on the transmission system, and prevent plastic deformation or micro-cracks on the surface of the cleaning part due to instantaneous overload, effectively improving the working reliability and durability of the cleaning head. The elastic element 5243 is made of a high elastic modulus material. In some embodiments, the positioning post 5244 can be integrally formed with the connecting rod 5242 to further improve the rigidity and coaxiality of the structure and reduce the eccentric inertial force during high-speed rotation. The positioning post 5244 can form a stepped structure with the main body of the connecting rod 5242 to facilitate the axial positioning of the elastic element 5243 and the stable application of the pre-compression force.

[0139] In some embodiments, the positioning pin 5244 can be threadedly engaged with the connecting rod 5242 to facilitate disassembly and assembly and preload adjustment, ensuring that the elastic element 5243 is always within the effective working range.

[0140] In some embodiments, the elastic element 5243 is a helical spring or a wave washer, which has stable elastic deformation characteristics and maintains clamping reliability under vibration and impact loads.

[0141] In some embodiments, the cleaning component holder 52 further includes a cover 525, which covers the outside of the clamping component 524 to form a closed protective structure, effectively preventing liquid and impurities from entering the transmission system during the cleaning process. The chuck 5241 is exposed outside the cover 525, facilitating quick docking and disassembly with the cleaning component, while ensuring direct transmission of rotational power.

[0142] A seal is provided between the chuck 5241 and the cover 525 to prevent leakage from causing internal corrosion or electrical short circuits. The seal forms a dynamic sealing fit with the rotating shaft section of the chuck 5241. The seal is fixedly connected to the connecting shaft 5233 and moves synchronously with the rotation of the chuck to ensure a stable and reliable sealing interface.
