Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical module production, in particular to a plugging device and a floating mechanism thereof. BACKGROUND

[0002] With the development of optical module production technology, there are technologies such as optical module coupling, module fiber plugging test, etc. which need to plug the module / instrument and the optical fiber.

[0003] At present, there are two ways of manual and automatic plugging of optical fiber in the process of module fiber plugging test and optical module coupling, among which the manual plugging of optical fiber has high labor cost and low efficiency, and lacks plugging positioning in the process, so that the coaxiality of the fiber insertion port / slot of the module or instrument and the optical fiber cannot be guaranteed. In view of the defects of the manual plugging of optical fiber, after further optimization, the automatic plugging of optical fiber and the device thereof are appeared, which solves the problems of high cost and low efficiency existing in the manual plugging of optical fiber.

[0004] However, this way and device are mainly used for plugging fixed optical fiber, specifically, the optical fiber is inserted into the fiber insertion port / slot of the module or instrument by the optical fiber automatic plugging device through the shaft or air cylinder. Although the existing optical fiber automatic plugging device has high automation degree, it often ignores the possible coaxiality difference between the optical fiber and the fiber insertion port / slot in the process of inserting or pulling out the optical fiber. This difference will cause additional stress between the optical fiber and the fiber insertion port / slot in the process of inserting or pulling out, resulting in damage to the optical fiber or the fiber insertion port / slot, causing optical loss and optical fiber end face contamination. SUMMARY

[0005] Therefore, it is necessary to provide a plugging device and a floating mechanism thereof for the damage to the optical fiber or the fiber insertion port / slot caused by the coaxiality difference between the optical fiber and the fiber insertion port / slot in the process of plugging.

[0006] A floating mechanism, comprising a fixed body and a plugging piece fixing assembly; the fixed body comprises a first matching surface; the plugging piece fixing assembly comprises a fixing part for fixing a plugging piece to be inserted or pulled out and a connecting part connected with the fixed body, the connecting part comprises a first matching surface; a floating gap is arranged between the first matching surface and the first matching surface, and the floating gap is provided with a first elastic element, so that the plugging piece fixing assembly can float relative to the fixed body.

[0007] The floating mechanism can solve the problem of damage to the insertion end of the plug-in part or the insertion port / slot of the plug-in body caused by additional stress between the plug-in part and the plug-in body due to the difference in coaxiality of the two during the insertion or extraction of the insertion end of the plug-in part into the insertion port / slot of the plug-in body. Specifically, when the floating mechanism is used in the optical module testing or coupling process, the problem of optical loss and fiber end face contamination caused by the difference in coaxiality between the insertion end of the optical fiber and the insertion port / slot of the module can be solved. The plug-in part is fixed to the plug-in part fixing assembly, and the connecting part of the plug-in part fixing assembly is floatingly connected to the fixed body. Specifically, the floating connection is achieved by providing a floating gap between the first matching surface and the first matching surface opposite to the connecting part of the plug-in part fixing assembly and the fixed body, and a first elastic element is arranged in the floating gap. The first elastic element is in a compressed state with the first matching surface and the first matching surface, that is, the first elastic element has a certain pre-pressure from the first matching surface and the first matching surface. The connecting part of the plug-in part fixing assembly has multiple degrees of freedom in the floating gap. In this way, during each insertion and extraction process, the plug-in part fixing assembly can slightly float within the floating gap relative to the fixed body. In the floating state, the insertion end of the plug-in part and the insertion port / slot of the plug-in body are adaptively matched, avoiding additional stress between the plug-in part and the plug-in body, and reducing the possibility of damage to the insertion end of the plug-in part and the insertion port / slot of the plug-in body due to stress.

[0008] In one embodiment, the fixed body is provided with a first matching hole, and the first matching surface includes the inner surface of the first matching hole. The connecting part of the plug-in part fixing assembly includes a connecting shaft extending into the first matching hole, and the first matching surface includes the outer side surface of the connecting shaft. The first elastic element is in a compressed state with the inner surface of the first matching hole and the outer side surface of the connecting shaft, respectively.

[0009] The floating mechanism allows the plug-in part fixing assembly to float more freely relative to the fixed body, so that the connecting part of the plug-in part fixing assembly has more degrees of freedom in the floating gap, that is, the plug-in part has more degrees of freedom relative to the fixed body. The insertion end of the plug-in part can be adaptively inserted into the insertion port / slot of the plug-in body, avoiding hard insertion and extraction, while ensuring the coaxiality of the insertion end of the plug-in part and the insertion port / slot of the plug-in body. The first matching surface is set as the inner surface of the first matching hole, and the first matching surface is set as the outer side surface of the connecting shaft. The floating gap and the first elastic element are arranged between the inner surface of the first matching hole and the outer side surface of the connecting shaft. When additional stress is generated between the plug-in part and the plug-in body due to the difference in coaxiality of the two during the insertion or extraction of the insertion end of the plug-in part into the insertion port / slot of the plug-in body, the plug-in part can be adaptively inserted / extracted in the axial direction of the slot, ensuring the coaxiality of the slot and avoiding additional stress caused by hard insertion and extraction.

[0010] In one of the embodiments, the first elastic element comprises one or more rubber rings sleeved on the outer side surface of the connecting shaft.

[0011] The floating mechanism sets the first elastic element as one or more rubber rings sleeved on the outer side surface of the connecting shaft, the inner ring surface of each rubber ring is sleeved on the outer side surface of the connecting shaft, and the outer ring surface of the rubber ring abuts against the inner surface of the first matching hole.

[0012] In one of the embodiments, an axial limiting structure is arranged between the fixed body and the connecting shaft, and the axial limiting structure can limit the axial displacement and self-rotation range of the connecting shaft relative to the fixed body in the floating gap.

[0013] The floating mechanism limits the axial displacement and self-rotation range of the connecting shaft by the axial limiting structure, so as to reduce the influence of the axial displacement and self-rotation of the connecting shaft relative to the fixed body in the floating gap on the insertion or extraction of the plug-in part.

[0014] In one of the embodiments, the axial limiting structure comprises a first pin, a second matching hole is radially arranged on the connecting shaft, the first pin is clearance-fitted in the second matching hole, and at least one end of the first pin is connected with the first matching surface of the fixed body.

[0015] The floating mechanism sets the first pin and the second matching hole clearance-fitted with the first pin, and the clearance between the first pin and the second matching hole is greater than the free displacement of the connecting shaft, so as to avoid interfering with the floating of the connecting shaft. The first pin limits the axial displacement and self-rotation range of the connecting shaft, and the structure is simple and the components for realizing the function are less.

[0016] In addition, the application further provides a plug-in device comprising the floating mechanism.

[0017] In one of the embodiments, the plug-in device comprises a plug-in body fixing assembly for fixing the plug-in body, the plug-in body is provided with a socket / slot capable of matching the insertion end of the plug-in part, and the plug-in device further comprises a reset mechanism, the reset mechanism comprises a first reset structure and a positioning body, the first reset structure is arranged on the plug-in part fixing assembly, the positioning body is provided with a second reset structure, and the first reset structure and the second reset structure are matched, so that the insertion end of the plug-in part is restored to the initial position before being inserted into the socket / slot of the plug-in body.

[0018] The plug-in device, under the premise of the floating mechanism, the plug-in part is adaptively inserted into the plug-in body each time. The first elastic element of the floating mechanism can be slightly plastically deformed due to the adaptive insertion into the slot of the plug-in body. After the plug-in body is pulled out, the first elastic element fails to restore the initial state, so that the position of the plug-in part changes, and the plug-in part cannot be inserted into the socket / slot of the plug-in body in the same axial direction each time. In order to reduce the influence of the position change on the repeatability of the next insertion of the plug-in part into the plug-in body, the first reset structure and the second reset structure are arranged to cooperate with each other. The starting position (axial direction) of the insertion end of the plug-in part before being inserted into the socket / slot of the plug-in body is positioned by the hard positioning between the first reset structure and the second reset structure, so that the position repeatability of the insertion end of the plug-in part is ensured to a certain extent, that is, the plug-in part can be inserted into the socket / slot of the plug-in body in the same axial direction each time.

[0019] In one of the embodiments, the reset mechanism further comprises a positioning body driving assembly capable of driving the positioning body to move in the plug-in direction.

[0020] The plug-in device, when the insertion end of the plug-in part approaches the socket / slot of the plug-in body, the positioning body driving assembly drives the positioning body to move away from the plug-in part fixing assembly, and the second reset structure is separated from the first reset structure. The plug-in part continues to be inserted into the socket / slot of the plug-in body, and can float within the gap range of the floating mechanism to be adaptively inserted into the socket / slot.

[0021] In one of the embodiments, the first reset structure comprises a third matching hole arranged on the plug-in part fixing assembly; and the second reset structure comprises a second pin protruding from the positioning body.

[0022] The plug-in device, before the plug-in part is inserted into the plug-in body, the floating mechanism gradually approaches the plug-in body fixing assembly, and the plug-in part fixing assembly gradually approaches the positioning body, the third matching hole gradually approaches the second pin, until the second pin matches the third matching hole, and the starting position of the insertion end of the plug-in part before being inserted into the socket / slot of the plug-in body is positioned.

[0023] In one of the embodiments, the second pin is in sliding connection with the positioning body.

[0024] The plug-in device, when the insertion end of the plug-in part approaches the guiding structure of the socket / slot port and continues to travel in the guiding structure, the second pin abuts against the third matching hole, and the second pin slides along the plug-in direction relative to the positioning body following the floating mechanism.

[0025] In one of the embodiments, the second pin is in sliding connection with the positioning body through a linear bearing.

[0026] The second pin can slide relative to the positioning body and rotate relative to the positioning body. In this way, when a slight self-rotation torque occurs in the second pin during operation, the second pin can slightly rotate relative to the positioning body. This is a reasonable arrangement and is conducive to prolonging the service life of the second pin and the positioning body.

[0027] In one embodiment, an external sleeve of the second pin is provided with a reset spring, which is arranged between the positioning body and the second pin to provide a reset force for moving the second pin relative to the positioning body towards the third matching hole.

[0028] The plug-in device is provided with a reset spring between the positioning body and the second pin. When the second pin abuts against the third matching hole and the second pin slides relative to the positioning body along the plug-in direction following the floating mechanism, the reset spring is compressed at this time. When the positioning body driving assembly drives the second pin to exit the third matching hole, the reset spring recovers and drives the second pin to reset (relative to the position of the positioning body), and at this time the floating mechanism is in a floating state, so that the plug-in part can be adaptively inserted into the slot.

DETAILED DESCRIPTION

[0037] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and claimed herein, and it is therefore intended that the present application not be limited to the embodiments presented herein. Indeed, these embodiments are included to enable practitioners to better understand the present application.

[0038] With reference to Figure 1 and Figure 5 , the present embodiment provides a floating mechanism 100 for fixing a plug-pull piece 20, so that the insertion end of the plug-pull piece 20 is inserted or pulled out relative to the insertion port / slot of a plug-pull body 30. The floating mechanism 100 is used to adaptively insert the insertion end of the plug-pull piece 20 into the insertion port / slot of the plug-pull body 30 in view of the coaxiality difference between the insertion end and the insertion port / slot. In the present embodiment, the floating mechanism 100 is applied to optical module coupling process or module fiber plug-pull test, i.e., the relative insertion or pulling out between the insertion end of the optical fiber and the slot / port of the module / instrument. It should be noted that the floating mechanism 100 is not limited to be applied to the optical module coupling process or module fiber plug-pull test, and the plug-pull piece 20 and the plug-pull body 30 can be any two mutually plugged parts / components.

[0039] With reference to Figure 1 , Figure 5 and Figure 6A floating mechanism 100, comprising a fixed body 110 and a plug-in part fixing assembly 120; the fixed body 110 comprises a first matching surface 1111; the plug-in part fixing assembly 120 comprises a fixing part 123 for fixing a plug-in part 20 to be inserted or pulled out and a connecting part 121 connected with the fixed body 110, the connecting part 121 comprises a first matching surface 1211. Continue to refer to Figure 5 And Figure 6 The first matching surface 1111 of the fixed body 110 and the first matching surface 1211 of the connecting part 121 are provided with a floating gap 140, and the floating gap 140 is provided with a first elastic element 150, so that the plug-in part fixing assembly 120 can float relative to the fixed body 110, that is, the plug-in part 20 fixed to the plug-in part fixing assembly 120 can float and displace relative to the fixed body 110. Specifically, one of the first matching surface 1211 and the first matching surface 1111 surrounds a receiving space, and the other surface is received in the receiving space, and the two have the floating gap 140 therebetween.

[0040] The floating mechanism 100 can solve the problem that the insertion end of the plug-in part 20 and the insertion port / slot of the plug-in body 30 are damaged due to the difference in coaxiality between the two during the insertion or pulling out of the insertion end of the plug-in part 20 relative to the insertion port / slot of the plug-in body 30. Specifically, when the floating mechanism 100 is used in an optical module coupling process, the optical loss and the contamination of the fiber end face caused by the difference in coaxiality between the insertion end of the optical fiber and the insertion port / slot of the module can be solved. The plug-in part 20, that is, the optical fiber, is fixed to the plug-in part fixing assembly 120, and the connecting part 121 of the plug-in part fixing assembly 120 is floatingly connected to the fixed body 110. Specifically, the floating connection is achieved by providing a floating gap 140 between the first matching surface 1111 and the first matching surface 1211 of the fixed body 110 and the connecting part 121 of the plug-in part fixing assembly 120, and providing a first elastic element 150 in the floating gap 140. The first elastic element 150 is in a compressed state with the first matching surface 1111 and the first matching surface 1211, that is, the first matching surface 1111 and the first matching surface 1211 have a certain pre-pressure on the first elastic element 150, and the connecting part 121 of the plug-in part fixing assembly 120 has multiple degrees of freedom in the floating gap 140. In this way, during each insertion and pulling out process, the plug-in part fixing assembly 120 can float slightly within the floating gap 140 relative to the fixed body 110. During the floating process, the insertion end of the plug-in part 20 and the insertion port / slot of the plug-in body 30 are adaptively matched, reducing the possibility of additional stress between the plug-in part and the plug-in body, and reducing the possibility of damage to the insertion end of the plug-in part 20 and the insertion port / slot of the plug-in body 30 due to stress.

[0041] Referring to Figure 5 and Figure 6 In an embodiment, the first matching surface 1111 is an inner surface of the first matching hole 111, and the first matching surface 1211 is an outer surface of the connecting shaft. The first elastic element 150 is in a compressed state with the inner surface of the first matching hole 111 and the outer surface of the connecting shaft.

[0042] The floating mechanism 100 makes the connecting part 121 of the plug-in part fixing assembly 120 have more degrees of freedom in the floating gap 140, that is, the plug-in part 20 has more degrees of freedom relative to the fixed body 110, that is, the insertion end of the plug-in part 20 has more degrees of freedom relative to the insertion port / slot of the plug-in body 30. The first matching surface 1111 is an inner surface of the first matching hole 111, and the first matching surface 1211 is an outer surface of the connecting shaft. The floating gap 140 and the first elastic element 150 are arranged between the inner surface of the first matching hole 111 and the outer surface of the connecting shaft. During the insertion or extraction of the insertion end of the plug-in part 20 relative to the insertion port / slot of the plug-in body 30, when additional stress is generated between the plug-in part 20 and the plug-in body 30 due to the difference in coaxiality, the stress is transferred from the fixed part 123 of the plug-in part fixing assembly 120 to the connecting shaft of the plug-in part fixing assembly 120, and then to the connecting shaft and the first elastic element 150 and to the first elastic element 150 and the fixed body 110. The first elastic element 150 deforms, and the first elastic element 150 has multiple deformation modes, and then the connecting shaft has multiple degrees of freedom relative to the first matching hole 111. The connecting shaft is flexible relative to the first matching hole 111, that is, the plug-in part fixing assembly 120 is flexible relative to the fixed body 110. Further, the plug-in part 20 fixed to the plug-in part fixing assembly 120 is also flexible relative to the plug-in body 30.

[0043] Continuing to refer to Figure 6 In an embodiment, the connecting shaft is a circular shaft. The connecting shaft relative to the first matching hole 111 includes but is not limited to the radial degree of freedom of the connecting shaft. It should be noted that the connecting shaft can also include but is not limited to a square shaft and a hexagonal shaft, but the circular shaft has more degrees of freedom.

[0044] Continuing to refer to Figure 6 In an embodiment, the first elastic element 150 includes one or more rubber rings arranged on the outer surface of the connecting shaft.

[0045] The floating mechanism 100 sets the first elastic element 150 as one or more rubber rings sleeved on the outer side surface of the connecting shaft. The inner ring surface of each rubber ring is sleeved on the outer side surface of the connecting shaft, and the outer ring surface of the rubber ring abuts against the inner surface of the first matching hole 111. Continue to refer to Figure 6 In an embodiment, preferably, two rubber rings are provided and symmetrically arranged in the floating gap 140 between the connecting shaft and the first matching hole 111, so that the floating of the connecting shaft relative to the first matching hole 111 is more stable, that is, the floating of the plug-in part fixing assembly 120 relative to the fixing body 110 is more stable, and the floating of the plug-in part 20 fixed on the plug-in part fixing assembly 120 relative to the plug-in body 30 is more stable. In this embodiment, the connecting shaft can float relative to the first matching hole 111 in any radial direction including but not limited to the radial direction of the connecting shaft. Specifically, during the insertion or extraction of the insertion end of the plug-in part 20 relative to the socket / slot of the plug-in body 30, when stress is generated between the plug-in part 20 and the plug-in body 30 due to the difference in coaxiality of the two, since the floating mechanism 100 is provided, part of the stress is transferred to the connecting shaft and the rubber ring and between the rubber ring and the first matching hole 111, and the rubber ring deforms. When the two rubber rings are subjected to the same force in the same direction, the connecting shaft can be displaced relative to the first matching hole 111 in one of the radial directions, that is, the central axis of the connecting shaft is translated before and after displacement. When the two rubber rings are subjected to different forces in different directions, the central axis of the connecting shaft is deflected before and after displacement. It should be noted that in addition to two rubber rings, one or more rubber rings can also be provided. When one rubber ring is provided, the contact area of the inner ring surface and the outer ring surface of the rubber ring with the outer side surface of the connecting shaft and the inner surface of the first matching hole 111 can be appropriately increased. Similarly, when multiple rubber rings are provided, the contact area of the inner ring surface and the outer ring surface of each rubber ring with the outer side surface of the connecting shaft and the inner surface of the first matching hole 111 can be appropriately reduced.

[0046] Preferably, the Shore hardness of the rubber ring is 40HS-70HS. It should be noted that in addition to the rubber ring, a sleeve ring structure made of other elastic materials can also be used. In addition, it should be noted that in addition to the one or more rubber rings, the first elastic element 150 can also be provided as one or more springs. When the spring is provided, a variable-diameter coil spring such as a volute coil spring or a conical coil spring can be used. The spring is arranged in the floating gap 140 between the inner surface of the first matching hole 111 and the outer side surface of the connecting shaft, and the inner surface of the first matching hole 111 and the outer side surface of the connecting shaft both have a certain pre-pressure on the spring. In addition to the rubber ring and the spring, the first elastic element 150 can also be provided as other elastic elements that enable the connecting shaft to float relative to the first matching hole 111 in the floating gap 140.

[0047] Referring to Figure 6 In an embodiment, the axial limiting structure 130 is arranged between the fixed body 110 and the connecting shaft, and is capable of limiting the axial displacement and self-rotation range of the connecting shaft relative to the fixed body 110 within the floating gap 140.

[0048] The floating mechanism 100 described above is arranged to limit the axial displacement and self-rotation range of the connecting shaft by the axial limiting structure 130, so as to reduce the influence of the axial displacement and self-rotation of the connecting shaft relative to the fixed body 110 within the floating gap 140 on the insertion or extraction of the plug-in part 20.

[0049] Continuing to refer to Figure 6 In an embodiment, the axial limiting structure 130 includes a first pin, and a second matching hole 122 is radially arranged on the connecting shaft, the first pin is gap-fitted in the second matching hole 122, and at least one end of the first pin is connected with the first matching surface 1111 of the fixed body 110.

[0050] The floating mechanism 100 described above is arranged to limit the axial displacement and self-rotation range of the connecting shaft by the axial limiting structure 130, so as to reduce the influence of the axial displacement and self-rotation of the connecting shaft relative to the fixed body 110 within the floating gap 140 on the insertion or extraction of the plug-in part 20. Figure 6 In an embodiment, the second matching hole 122 is arranged through the connecting shaft, the first pin is gap-fitted in the second matching hole 122, and both ends of the first pin are respectively connected with the first matching surface 1111 of the fixed body 110. Compared with the above-mentioned mode in which one end of the first pin is fixed to the fixed body 110, the connection between the first pin and the fixed body 110 is more reliable.

[0051] Continuing to refer to Figure 6 In an embodiment, the first pin is arranged between two rubber rings, so that the floating is more balanced, and the stress on the rubber rings on both sides is more uniform. In an embodiment, the second matching hole 122 is longitudinally arranged on the connecting shaft. It should be noted that the second matching hole 122 can be arranged in any radial direction of the connecting shaft, and a connecting hole for connecting both ends of the first pin is arranged on the first matching surface 1111.

[0052] Continuing to refer to Figure 6In an embodiment, the fixing body 110 comprises a cover plate 112 and a base 113 detachably connected with the cover plate 112, and a semicircular through slot is formed on each of the cover plate 112 and the base 113, and when the cover plate 112 is fixed on the base 113, the two semicircular through slots are spliced to form the first matching hole 111, and the inner surface of the first matching hole 111 forms the first matching surface 1111, and a connecting hole connecting two ends of the first pin is formed on the semicircular through slot of the cover plate 112 and the base 113 respectively. The fixing body 110 is provided as two detachable parts, which is more reasonable and facilitates the assembly of the connecting shaft, the first elastic element 150 and the first pin.

[0053] In addition, referring to Figure 1-7 The application also provides a plug-in device 10 comprising a working platform and the floating mechanism 100.

[0054] Continuing to refer to Figure 1 、 Figure 2 and Figure 3 In an embodiment, the plug-in device 10 comprises a working platform, a floating mechanism 100 fixed with a plug-in part 20, a plug-in body fixing assembly 300 fixed with a plug-in body 30 and a reset mechanism 200. The plug-in body 30 is provided with a socket / slot capable of cooperating with the insertion end of the plug-in part 20, and a guide structure is arranged at the port position of the socket / slot, and the insertion end of the plug-in part 20 is inserted into the socket / slot under the guidance of the guide structure. The floating mechanism 100 comprises a floating mechanism driving assembly 170 arranged on the working platform, and the floating mechanism driving assembly 170 can drive the fixing body 110 and the plug-in part fixing assembly 120 to move relative to the working platform along the X axis, the Y axis and the Z axis, for process control of the floating mechanism 100 driving the plug-in part 20 to insert or pull out relative to the plug-in body 30.

[0055] Referring to Figure 1-4 In an embodiment, the reset mechanism 200 comprises a first reset structure 220 and a positioning body 210; the first reset structure 220 is arranged on the second matching surface 160 of the floating mechanism 100, and the second matching surface 160 is opposite to the plug-in body fixing assembly 300; the positioning body 210 comprises a second matching surface 211 opposite to the second matching surface 160; the positioning body 210 is provided with a second reset structure 230 protruding from the second matching surface 211; the first reset structure 220 cooperates with the second reset structure 230 to make the insertion end of the plug-in part 20 return to the initial position (axial direction) before being inserted into the socket / slot of the plug-in body 30. The reset mechanism 200 further comprises a positioning body driving assembly 260 arranged on the working platform, and the positioning body driving assembly 260 can drive the positioning body 210 to move relative to the working platform along the X axis.

[0056] The plug-in device 10, in the presence of the floating mechanism 100, the plug-in part 20 is adaptively inserted into the plug-in body 30 each time, the first elastic element 150 of the floating mechanism 100 can be slightly plastically deformed due to the slot of the adaptive plug-in body 30, and the first elastic element 150 cannot restore the initial state after the plug-in body 30 is pulled out, so that the position of the plug-in part 20 will change, and the plug-in part 20 cannot be inserted into the next plug-in body 30 to be tested each time in the same axial direction (initial position), which may cause a large axial angle error between the insertion end of the plug-in part 20 and the insertion port / slot of the next plug-in body 30 to be tested, and additional stress between the insertion end of the plug-in part 20 and the plug-in body 30. In order to reduce the influence of the position change on the position repeatability of the plug-in part 20 before the next insertion into the plug-in body 30, the first reset structure 220 and the second reset structure 230 are arranged to cooperate with each other, and the initial position (axial direction) of the insertion end of the plug-in part 20 before being inserted into the insertion port / slot of the plug-in body 30 is positioned by the hard positioning between the first reset structure 220 and the second reset structure 230, which can ensure the position repeatability of the insertion end of the plug-in part 20 to a certain extent, that is, the plug-in part 20 can be inserted into the insertion port / slot of the plug-in body 30 in the same axial direction each time. When the insertion end of the plug-in part 20 approaches the insertion port / slot of the plug-in body 30, the positioning body driving assembly 260 drives the positioning body 210 to move away from the plug-in part fixing assembly 120, and after the second reset structure 230 is separated from the first reset structure 220, the plug-in part 20 continues to be inserted into the insertion port / slot of the plug-in body 30, that is, the plug-in part 20 can be adaptively inserted into the insertion port / slot within the gap range of the floating mechanism 100. It should be noted that the insertion process is as follows: the floating mechanism 100 is driven by the floating mechanism driving assembly 170 to move on the working platform and gradually approach the plug-in body fixing assembly 300, and at the same time, the plug-in part 20 gradually approaches the plug-in body 30, the first reset structure 220 arranged on the floating mechanism 100 cooperates with the second reset structure 230 arranged on the positioning body 210 to position the initial position (initial axial angle) of the insertion end of the plug-in part 20 before being inserted into the insertion port / slot of the plug-in body 30. Then the floating mechanism 100 drives the plug-in part 20 to continue to advance, and when the insertion end of the plug-in part 20 approaches the insertion port / slot of the plug-in body 30, the positioning body driving assembly 260 drives the second reset structure 230 to retreat, releases the plug-in part 20, and makes the plug-in part 20 in a floating state, at this time, the insertion end of the plug-in part 20 and the insertion port / slot of the plug-in body 30 are adaptively matched, and due to the floating relationship, the possibility of damage between the plug-in part 20 and the plug-in body 30 due to additional stress is reduced, and the plug-in part 20 continues to advance under the driving of the floating mechanism driving assembly 170 until the action is completed.

[0057] The pulling-out process: the floating mechanism 100 is driven to retreat by the floating mechanism driving assembly 170, and the plug-in part 20 is in a floating state. At this time, the insertion end of the plug-in part 20 and the insertion port / slot of the plug-in body 30 are adaptively matched. Due to the floating relationship, the possibility of damage between the plug-in part 20 and the plug-in body 30 due to additional stress is reduced. The optical fiber continues to retreat under the driving of the floating mechanism driving assembly 170 until the action is completed.

[0058] Continuing to refer to Figure 1 In an embodiment, the floating mechanism driving assembly 170 is provided to include a Y-axis electric actuator 1701, an X-axis electric actuator 1702, and a Z-axis electric actuator 1703. It should be noted that the Y-axis electric actuator 1701, the X-axis electric actuator 1702, and the Z-axis electric actuator 1703 can also be provided in other forms, such as a single-axis module composed of a hydraulic cylinder, a stepping motor, a servo motor, and a lead screw. The layout mode between the X-axis, Y-axis, and Z-axis of the floating mechanism driving assembly 170 can also be in other forms, which can meet the requirements of the X-direction, Y-direction, and Z-direction freedom of the floating mechanism 100 relative to the workbench. The plug-in body fixing assembly 300 includes a fixed support 310 and a fixing module 320 provided on the fixed support 310. The fixing module 320 fixes the plug-in body 30 on the fixed support 310. The setting form of the fixing module 320 includes but is not limited to clamps, bolts, and screws. Continuing to refer to Figure 1 In an embodiment, the positioning body driving assembly 260 is provided as a driving cylinder 261. The floating mechanism driving assembly 170 and the positioning body driving assembly 260 are both provided on the workbench. It should be noted that the positioning body driving assembly 260 can also be provided in other forms, such as a single-axis module composed of a hydraulic cylinder, a stepping motor, a servo motor, and a lead screw.

[0059] Continuing to refer to Figure 1-4 In an embodiment, the first reset structure 220 includes a third matching hole opened on the second matching surface 160; and the second reset structure 230 includes a second pin protruding from the second matching surface 211.

[0060] The above plug-in device 10, before the plug-in part 20 is inserted into the plug-in body 30, the floating mechanism 100 gradually approaches the plug-in body fixing assembly 300 while the floating mechanism 100 gradually approaches the positioning body 210, the third matching hole gradually approaches the second pin, and then the second pin and the third matching hole are matched, and the insertion end of the plug-in part 20 is inserted into the initial position of the insertion port / slot of the plug-in body 30 before the insertion end of the plug-in part 20 is inserted into the insertion port / slot of the plug-in body 30.

[0061] Continuing to refer to Figure 1-4In an embodiment, the second pin is in sliding connection with the positioning body 210, so that the second pin can move relative to the positioning body 210 along the plug-in direction. In this embodiment, when the insertion end of the plug-in part 20 approaches the guide structure of the socket / slot port and continues to travel in the guide structure, the second pin abuts against the third matching hole, and then the second pin slides along the plug-in direction relative to the positioning body 210 following the floating mechanism 100. Specifically, the second pin is provided with a protruding abutting part at one end close to the floating mechanism 100, and the port position of the third matching hole is provided with a concave abutting part in cooperation with the protruding abutting part. The protruding abutting part includes but is not limited to a tapered shape, a semicircular shape, and the like, and the concave abutting part is provided in cooperation with the protruding abutting part. It should be noted that the second pin can also be fixedly arranged on the positioning body 210, so that when the insertion end of the plug-in part 20 approaches the guide structure of the socket / slot port and continues to travel in the guide structure, the second pin continues to penetrate into the third matching hole. Until the insertion end of the plug-in part 20 approaches the slot under the guidance of the guide structure, the positioning body 210 drives the second pin to exit from the third matching hole. In addition, it should be noted that the first reset structure 220 and the second reset structure 230 can be provided with a guide hole on the positioning body 210, and a guide column matched with the guide hole on the fixed assembly 120 of the plug-in part 20, in addition to the above structures. The first reset structure 220 and the second reset structure 230 can also be provided as any rigidly matched guide structure.

[0062] Continuing to refer to Figure 1 and Figure 2 In an embodiment, the second pin is in sliding connection with the positioning body 210 through a linear bearing 250. In the above plug-in device 10, the second pin can slide relative to the positioning body 210, and can also rotate relative to the positioning body 210. In this way, when a small self-rotation torque occurs to the second pin during operation, the second pin can rotate slightly relative to the positioning body 210. This reasonable arrangement is conducive to prolonging the service life of the second pin and the positioning body 210.

[0063] Continuing to refer to Figure 1 and Figure 2In an embodiment, the second pin is externally sleeved with a reset spring 240, which is arranged between the positioning body 210 and the second pin to provide a reset force for the second pin to move relative to the positioning body 210 in a direction close to the third matching hole. When the second matching surface 160 and the second matching surface 211 are close to each other, the second pin abuts against the third matching hole, and then the second pin slides relative to the positioning body 210 following the floating mechanism 100, the reset spring 240 is compressed; when the second matching surface and the second matching surface 211 are away from each other, the reset spring 240 is restored, and then the second pin is reset. It should be noted that the arrangement mode of the reset spring 240 and the positioning body 210, and the reset spring 240 and the second pin is not limited, which can be abutting or fixedly connected.

[0064] The plug-in device 10 is applied to an optical module coupling process, that is, the plug-in part 20 is an optical fiber, and the plug-in body 30 is an optical module. The working process of the plug-in device 10 is as follows:

[0065] The insertion process: the optical fiber is driven by the floating mechanism 100 to move forward, when the optical fiber approaches the module, the first reset structure 220 arranged on the floating mechanism 100 cooperates with the second reset structure 230 arranged on the positioning body 210, and the insertion end of the optical fiber is positioned at the starting position before the slot of the module. Then the floating mechanism 100 drives the optical fiber to continue to move forward, when the insertion end of the optical fiber enters the guide structure arranged at the port of the slot and continues to move forward under the guidance of the guide structure, the second reset structure 230 moves relative to the positioning body 210 under the pushing of the first reset structure 220, until the insertion end is close to the slot of the module, the positioning body 210 drives the second reset structure 230 to retreat, the second reset structure 230 is separated from the first reset structure 220, and the optical fiber is in a floating state. At this time, the insertion end of the optical fiber and the socket / slot of the module are adaptively matched. Due to the floating relationship, the possibility of damage between the optical fiber and the module due to additional stress is reduced. The optical fiber continues to move forward under the driving of the floating mechanism 100, until the action is completed.

[0066] The pulling-out process: the floating mechanism 100 is driven by the floating mechanism 100 to retreat, and the optical fiber is in a floating state. At this time, the insertion end of the optical fiber and the socket / slot of the module are adaptively matched. The optical fiber continues to retreat under the driving of the floating mechanism 100, until the action is completed.
