Description

Technical Field

[0001] This invention belongs to the field of optical module coupling technology, and particularly relates to an optical fiber assembly insertion and removal device and method. Background Technology

[0002] In the production process of optical modules, test optical fibers need to be connected and coupled to the optical components of the optical module for testing. Traditionally, this connection is mostly done manually, for example, by holding the connector and inserting it into the interface of the optical module, then unplugging it after testing. However, with the rapid development of optical modules, traditional manual methods are no longer suitable for the production needs due to low production efficiency and high labor costs. The gradual replacement of manual methods with automated machinery is an inevitable trend.

[0003] In existing automated mechanical methods, the insertion and removal of optical fibers and optical modules can only be done by hard insertion and removal, which can easily cause damage and contamination to the coupling end face between the optical fiber and the optical module, and may even cause excessive optical path loss, directly affecting the product yield and reliability of the optical module.

[0010] Preferably, when the gripper pushes against the first protrusion, the gripper and the first protrusion are in point contact or line contact.

[0011] Preferably, the first protrusion is a cylinder, polygonal prism, or elliptical cylinder whose central axis extends in a left-right direction perpendicular to the insertion / extraction direction.

[0014] Preferably, the gripper has a pair of gripping arms located on the left and right sides of the base body;

[0015] The first positioning structure is a protrusion located on the left and right sides of the base, and the second positioning structure is a positioning groove located on the clamping arm, and a portion of the groove wall of the positioning groove is configured as the support portion; or, the first positioning structure is a positioning groove located on the left and right sides of the base, and the second positioning structure is a protrusion located on the clamping arm, and a portion of the surface of the protrusion is configured as the support portion.

[0016] When the gripper clamps the seat, the protrusion and the positioning groove are in surface contact or in line contact at at least two positions in the vertical direction; when the gripper releases the seat, the protrusion and the positioning groove remain in contact so that the support lifts the fixed seat.

[0017] Preferably, the positioning groove is a V-shaped groove with a first included angle, and the protrusion is a V-shaped convex ridge with a second included angle, wherein the first included angle and the second included angle are the same.

[0018] Preferably, the fixing base further includes a second protrusion extending out of the base body in a direction perpendicular to the insertion / removal direction, and the second protrusion, the clamp, and the first protrusion are arranged sequentially along the fiber insertion direction.

[0019] Preferably, the gripper can move relative to the fixing seat in the insertion / removal direction between the first protrusion and the second protrusion.

[0020] Preferably, the insertion / removal device further includes a release mechanism, the release mechanism comprising:

[0021] A release drive element fixedly mounted on the drive mechanism; and,

[0027] To achieve the above-mentioned objective, one embodiment of the present invention also provides a method for inserting and removing an optical fiber assembly, wherein the insertion / removal device is used to insert or remove the connector of the optical fiber assembly into a slot, and the insertion / removal method includes a fiber insertion method:

[0028] The grippers clamp the base of the fixing seat so that the connector of the optical fiber assembly mounted on the base is in the initial orientation;

[0029] The drive mechanism drives the clamping mechanism to move from the starting position along the fiber insertion direction to the middle position, during which the grippers keep the clamping body; the middle position is the position where the end of the connector reaches the slot opening;

[0030] The gripper releases the base, and the drive mechanism drives the clamping mechanism to continue moving from the middle position along the fiber insertion direction to the target position where the fiber optic assembly is inserted. During this period, the gripper remains released from the base and drives the fixing base to move along the fiber insertion direction by pushing against the first protrusion.

[0033] Preferably, the insertion / removal method further includes a fiber optic unplugging method:

[0035] Preferably, the fiber pulling method further includes: a pressing member of the plugging and unplugging device presses a buckle of the connector of the optical fiber component to unlock the connector of the optical fiber component from the slot.

[0036] Compared with the prior art, the beneficial effects of an embodiment are as follows: during fiber insertion, first, the seat body is clamped by the clamping jaws to ensure that the connector of the optical fiber component can be accurately and preliminarily mated into the optical fiber interface of the optical module at a preset initial angle. Then, the fixed seat continues to move in a free state that can move relative to the clamping jaws to adapt to the angle of the optical fiber interface, so that the optical fiber component is inserted in a highly adaptive state, thereby solving the problems of damage and dirt on the coupling end face caused by hard plugging throughout the fiber insertion process in the prior art, and ensuring the product yield and reliability of the optical module; moreover, the connection structure between the fixed seat and the transmission seat is simple. During the fiber insertion process, the fixed seat is completely driven forward by the clamping mechanism, with a high degree of freedom of movement, the overall structure is simple, and the processing and assembly of the device are easy and the cost is low.

[0043] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0044] Refer Figure 1, an embodiment of the present invention provides a plugging device 100 for inserting a fiber optic component 3 into a slot or pulling it out of the slot. In the accompanying drawings, the slot is exemplified as the fiber optic interface 1a of the optical module 1. It can be understood that, in addition to the fiber optic interface 1a of the optical module 1, the slot can also be implemented as other structures adapted to the plugging and unplugging of the fiber optic component 3.

[0045] For the convenience of understanding and illustration, hereinafter, the front-back direction is defined based on the plugging and unplugging direction of the fiber optic component 3. And specifically, the fiber insertion direction of the fiber optic component 3 is defined as "front", and the fiber pulling direction of the fiber optic component 3 is defined as "back". At the same time, the left-right direction is defined as the direction perpendicular to both the plugging and unplugging direction and the vertical direction.

[0046] The plugging device 100 includes a fixing mechanism 10, a driving mechanism, a fixing seat 30, and a clamping mechanism 40.

[0047] Among them, the fixing mechanism 10 is used to fix the mating optical module 1 to restrict the optical module 1 from moving relative to the fixing mechanism 10 in the front-back, left-right, up-down, etc. directions. That is, the optical module 1 to be tested or coupled can be placed on the fixing mechanism and fixed in position by the fixing mechanism 10, so as to facilitate the insertion or extraction of the fiber optic component 3 into or out of the optical module 1.

[0048] Figure 2 FIG. shows a specific structure of the fixing mechanism 10, which includes a main seat 11, a baffle 111, a slider 12, a clamping block 121, and a spring 13. The main seat 11 has a through-channel 112 that penetrates left and right and a through-hole 113 that extends upward from the through-channel 112; the baffle 111 is fixed to one side of the main seat 11 (such as Figure 2 the side indicated by the arrow A in FIG.) to block the through-channel 112; the slider 12 is configured to slide left and right within the through-channel 112; the clamping block 121 is fixed at the upper groove 120 of the slider 12 and extends upward from the through-hole 113 to the upper part of the main seat 11; the spring 13 is clamped between the slider 12 and the baffle 111 and always provides a driving force for the slider 12 to move away from the baffle 111. Thus, when the optical module 1 is placed above the main seat 11, the abutting convex block 114 and the clamping block 121 on the upper part of the main seat 11 clamp the optical module 1 left and right to achieve the fixed mating of the optical module 1 on the fixing mechanism 10. Of course, the specific structure of the fixing mechanism 10 is not limited to this, and it can be implemented using any feasible existing technology.

[0049] Referring to Figure 1 , the driving mechanism includes a driving member 21 and a transmission seat 22 connected to the driving member 21. The driving member 21 is used to drive the transmission seat 22 to move along the plugging and unplugging direction. Specifically, it can be set as any one of a cylinder, a hydraulic cylinder, a motor, etc., or it can be set as a combination formed by any one of a cylinder, a hydraulic cylinder, a motor and any one of a return spring and a return magnetic member.

[0050] Reference Figure 3 , the fixed seat 30 includes a seat body 33 and a first convex column 32a. Among them, the seat body 33 is used to fixedly connect the optical fiber component 3. Specifically, the optical fiber component 3 includes an optical fiber 3a and a connector 3b at the end of the optical fiber 3a. The connector 3b is fixedly connected in the seat body 33 so that the optical fiber component 3 can be inserted or pulled out of the optical module 1 by the fixed seat 30. Regarding the fixing method of the seat body 33 and the connector 3b, the connector 3b can be locked in the card slot of the seat body 33 through a buckle structure to limit the movement of the connector 3b relative to the fixed seat 30 in the front-back, left-right, up-down and other directions. However, it can be understood that this application is not limited thereto, and any feasible prior art can be adopted for implementation. The first convex column 32a protrudes from the seat body 33 in a direction perpendicular to the insertion and extraction direction (such as including but not limited to the left-right direction, the vertical direction), that is, the first convex column 32a is not provided on the two end faces of the seat body 33 in the insertion and extraction direction, but protrudes from the side of the seat body 33.

[0051] The clamping mechanism 40 is installed on the transmission seat 22 and moves along the insertion and extraction direction of the optical fiber component 3 under the drive of the drive mechanism. Specifically, the clamping mechanism 40 includes a clamping jaw 42 and a clamping drive member 41. Among them, the clamping jaw 42 and the first convex column 32a are arranged in sequence along the fiber insertion direction of the optical fiber component 3. In this way, the clamping jaw 42 is arranged behind the first convex column 32a so that the clamping jaw 42 can drive the fixed seat 30 to move along the fiber insertion direction by pushing against the first convex column 32a. The clamping drive member 41 is fixedly installed on the transmission seat 22 and is used to drive the clamping jaw 42 to clamp or loosen the seat body 33. Specifically, it can be set as any one of a cylinder, a hydraulic cylinder, a motor, etc., or it can be set as a combination formed by any one of a cylinder, a hydraulic cylinder, a motor and any one of a return spring and a return magnetic member.

[0052] In this application, the seat body 33 is provided with a first positioning structure. Correspondingly, the clamping jaw 42 is provided with a second positioning structure and a supporting portion. When the clamping jaw 42 clamps the seat body 33, the first positioning structure and the second positioning structure cooperate to position the connector 3b of the optical fiber component 3, for example, to keep the connector 3b at a preset initial angle / position (specifically, it can be preset by the adjusting component 222 described later), so as to facilitate the insertion of the connector 3b towards the optical fiber interface 1a of the optical module 1 at this initial angle / position during the fiber insertion process. When the clamping jaw 42 loosens the seat body 33, the clamping jaw 42 only supports the fixed seat 30 vertically upward in a direction perpendicular to the insertion and extraction direction, or in other words, the clamping jaw 42 supports the fixed seat 30 vertically. In this way, the fixed seat 30 can freely move 360° relative to the clamping jaw 42 in the left-right direction, the vertical direction, etc., such as slight movement, rotation, deflection, etc.

[0053] Thus, compared to the prior art, the insertion and removal device 100 of this embodiment can, during the insertion process of the optical fiber assembly 3 and the optical module 1 (i.e., during fiber insertion): first, the clamping jaws 42 clamp the base 33 to position the connector 3b, so as to ensure that the connector 3b can be accurately initially mated into the optical fiber interface 1a at a preset initial angle, for example, so that the front end of the connector 3b just enters the guide port of the optical fiber interface 1a but has not yet been inserted into the coupling position; then, the clamping jaws 42 are released from the base 33, and the clamping jaws 42 push against the first protrusion 32a to drive the fixing seat 30 to continue moving, so that the fixing seat The fixed base 30 can move forward freely in a left-right and vertical relative state to adapt to the angle of the fiber optic interface 1a. Under the guidance of the fiber optic interface 1a, it finally completes the insertion of the fiber optic component 3 and the optical module 1 into place. This solves the problem of damage and contamination of the coupling end face caused by the hard insertion process throughout the fiber insertion process in the prior art, and ensures the product yield and reliability of the optical module. In addition, the fixed base 30 is indirectly connected to the transmission base 22 through the clamping mechanism 40. During the fiber insertion process, the fixed base 30 is driven forward by the clamping mechanism 40. It has a high degree of freedom of movement and a simple overall structure.

[0054] In this embodiment, the specific structure of the transmission seat 22 will be detailed as follows: Figure 1 The transmission seat 22 includes a sliding seat 221, a driving seat 223, several adjusting components 222, and a driven seat 224.

[0055] The sliding seat 221 is mounted on the output shaft of the drive member 21. The drive member 21 drives the transmission seat 22 to move along the insertion and removal direction by driving the sliding seat 221.

[0056] The driven seat 224 is fixedly installed with the clamping drive member 41 of the clamping mechanism 40, and the driven seat 224 is connected to the driving seat 223. The driving force provided by the drive member 21 in the insertion and extraction direction is transmitted to the driven seat 224 through the driving seat 223.

[0057] The aforementioned adjustment components 222 are disposed between the sliding seat 221 and the driving seat 223. Specifically, they may include any one or a combination of the following: a front-back adjuster for correcting the front-back position of the driving seat 223; a left-right adjuster for correcting the left-right position of the driving seat 223; a height adjuster for correcting the vertical position of the driving seat 223; and an angle adjuster for correcting the left-right deflection angle, vertical deflection angle, and left-right torsion angle of the driving seat 223. Thus, based on the aforementioned adjustment components 222, and the driving seat 223 driving the driven seat 224 to move, fine-tuning of the initial angles of the connector 3b in various directions can be achieved. The specific implementation of the aforementioned adjustment components 222 can be carried out using any feasible existing technology, and will not be elaborated further.

[0058] Furthermore, participantsFigure 3 When the gripper 42 moves forward and pushes against the first protrusion 32a, the gripper 42 and the first protrusion 32a are in line contact or point contact. In this way, during the fiber insertion process and when the gripper 42 releases the seat 33, it can ensure that the gripper 42 can abut against the first protrusion 32a to push the fixing seat 30 forward, and it can also avoid excessive friction between the gripper 42 and the first protrusion 32a, which would affect the flexibility of the fixing seat 30 in the direction perpendicular to the insertion direction relative to the gripper 42. This ensures that the insertion process of the fiber optic assembly 3 into the optical module 1 is more adaptive and more flexible, and can better adapt to the fiber optic interface 1a. In this way, it avoids problems such as fiber core end face damage and dirt caused by slight angular deviation between the connector 3b and the fiber optic interface 1a.

[0059] Referring to the specific example in the accompanying drawings, when the gripper 42 moves forward against and pushes the first protrusion 32a, the gripper 42 and the first protrusion 32a are in line contact. Specifically, the front surface of the gripper 42 is configured as a plane perpendicular to the insertion / removal direction; the first protrusion 32a is configured as a cylinder extending along the left-right direction along its central axis, having a cylindrical surface, with an axial line on the last side of this cylindrical surface contacting the front surface of the gripper 42. Of course, the configuration of the first protrusion 32a and the front surface of the gripper 42 is not limited to that shown in the accompanying drawings. For example, the first protrusion 32a can also be a elliptical cylinder extending along the left-right direction along its central axis, or it can be a shape with a semi-cylindrical surface, an arc-shaped cylinder surface, or other shapes with arcuate surfaces, or it can have a triangular prism surface, a square pyramid surface, or other polygonal prisms.

[0060] One or more first protrusions 32a are provided on both the left and right sides of the base 33. For example, a pair of first protrusions 32a are provided on each side as shown in the figure, but it is not limited to this. In this way, by providing first protrusions 32a on both the left and right sides, the positional matching between the gripper 42 and the fixed base 30 can be improved when the gripper 42 abuts against the first protrusions 32a, and the pushing force of the gripper 42 on the fixed base 30 can be balanced from left to right, so as to prevent the fixed base 30 from deflecting relative to the gripper 42.

[0061] Furthermore, participants Figure 4 and Figure 5The gripper 42 has a pair of gripping arms located on the left and right sides of the fixed base 30. The pair of gripping arms can move closer to each other to clamp the base 33, and conversely, move further apart to release the base 33. Specifically, in the example in the attached drawing, each gripping arm has a slider 421 at its upper part; the lower part of the gripping drive member 41 is provided with a left-right extending groove 410. The slider 421 slides left and right within the groove 410 under the drive of the gripping drive member 41, so as to realize that the pair of gripping arms move closer or further apart. Of course, the structure of the gripper 42 is not limited to this. For example, in a variation embodiment, one gripping arm can be fixed to the gripping drive member 41, while the other gripping arm can be slidably engaged in the groove 410 via the slider 421, which can also realize that the pair of gripping arms move closer or further apart.

[0062] The clamping arm has a positioning groove 422 recessed in the left-right direction. The positioning groove 422 is specifically located on the side (or inner side) of the clamping arm facing the base 33. This positioning groove 422 is the second positioning structure. Correspondingly, the left and right sides of the base 33 are provided with protrusions 31, which are the first positioning structures.

[0063] When the gripper 42 clamps the base 33, the protrusion 31 and the positioning groove 422 are in surface contact or in line contact at least two (e.g., three) positions in the vertical direction, so that the gripper 42 and the base 33 are firmly and stably engaged, avoiding misalignment or accidental movement between the gripper 42 and the fixed base 30, and ensuring that the insertion and removal angle of the fixed base 30 remains constant when the gripper 42 clamps the base 33 twice, so that the fiber optic assembly 3 can be inserted into the guide port of the fiber optic interface 1a of the optical module 1 at the preset initial angle (or calibration angle) each time.

[0064] In terms of specific configuration, in this embodiment, the positioning groove 422 is generally V-shaped, having an upper groove wall 422a extending obliquely upward from the bottom of the groove and a lower groove wall 422b extending obliquely downward from the bottom of the groove; correspondingly, the protrusion 31 is generally V-shaped, having an upper surface 31a and a lower surface 31b. When the gripper 42 clamps the seat 33, surface 31a contacts and adheres to the groove wall 422a, and surface 31b contacts and adheres to the groove wall 422b.

[0065] The included angle between surfaces 31a and 31b (i.e., the included angle of the positioning groove 422) is the same as the included angle between groove walls 422a and 422b (i.e., the included angle of the V-shaped convex ridge). In the attached figure, the included angle between groove walls 422a and 422b is approximately 90° (i.e., the surfaces are perpendicular). Groove wall 422a extends obliquely upward at a 45° angle to the horizontal plane, and groove wall 422b extends obliquely downward at a 45° angle to the horizontal plane. Of course, the specific angle between groove walls 422a and 422b, as well as the angle between groove walls 422a / 422b and the horizontal plane, are not limited to this example.

[0066] Furthermore, a portion of the groove wall of the positioning groove 422 constitutes the support portion. Specifically, in this embodiment, the groove wall 422b constitutes the support portion. When the gripper 42 releases the seat 33, the surface 31b of the protrusion 31 contacts and supports the groove wall 422b, so that the positioning groove 422 supports the fixed seat 30 from below.

[0067] As can be seen from the above, in this embodiment, the support part on the gripper 42 is constructed by the second positioning structure. In other words, the support part and the second positioning structure are integrated into the same component, which can simplify the structure of the gripper 42.

[0068] It is understood that, in the implementation of the variation, the positioning groove 422 and the protrusion 31 can be interchanged. That is, the positioning groove is located on the left and right sides of the seat 33 to form the first positioning structure, while the protrusion is located on the clamping arm to form the second positioning structure, and part of the surface of the protrusion forms the support part.

[0069] Furthermore, when the driving mechanism drives the clamping mechanism 40 to move along the fiber pulling direction, the gripper 42 drives the fixing seat 30 to move backward, thereby realizing the fiber optic assembly 3 being pulled out of the optical module 1, that is, completing the fiber pulling process. As is known in the art, after the fiber optic assembly 3 with the latch 31b is inserted into the optical module 1, the latch 31b will be locked in the card hole of the optical module 1 to ensure a stable connection between the fiber optic assembly 3 and the optical module 1; when the fiber optic assembly 3 is pulled out of the optical module 1, the latch 31b needs to be released from the card hole of the optical module 1 before the fiber optic assembly 3 can be disengaged from the optical module 1.

[0070] In this embodiment, the reference Figure 3 The insertion and removal device 100 also includes a release mechanism 50, so that the insertion and removal device 100 is compatible with the fiber optic assembly 3 having a snap-fit ​​31b.

[0071] Specifically, the release mechanism 50 includes a release drive member 51 fixedly mounted on the transmission base 22 and a pressing member 52 disposed on the release drive member 51. The release drive member 51 is used to drive the pressing member 52 to move perpendicular to the insertion / removal direction to press or release the latch 31b. It can be configured as any one of a cylinder, hydraulic cylinder, motor, etc., or it can be configured as a combination formed by any one of a cylinder, hydraulic cylinder, motor and any one of a return spring and a return magnetic member. In this way, when it is necessary to pull out the connector 3b of the fiber optic assembly 3 from the optical module 1, the pressing member 52 can press the latch 31b of the connector 3b to release the latch 31b from the latch hole of the optical module 1, thereby facilitating the smooth detachment of the fiber optic assembly 3 from the optical module 1 along the fiber pulling direction.

[0072] In this embodiment, the pressing member 52 moves vertically to press or release the latch 31b of the connector 3b. For example, as shown in the figure, the pressing member 52 moves vertically upward to press the latch 31b of the connector 3b and vertically downward to release the latch 31b of the connector 3b. Of course, this is only one specific example of the movement direction of the pressing member 52. In variant embodiments, based on the changes in the positions of the pressing member 52 and the connector 3b, the movement direction of the pressing member 52 can also be changed to a forward / backward direction or other directions.

[0073] Furthermore, the mounting base 30 also includes a second protrusion 32b protruding from the base body 33 in a direction perpendicular to the insertion / removal direction. The first protrusion 32a, the gripper 42, and the second protrusion 32b are arranged sequentially along the fiber pulling direction, that is, the gripper 42 is located between the first protrusion 32a and the second protrusion 32b. In this way, the gripper 42 can push the second protrusion 32b to drive the mounting base 30 to move backward, thereby completing the removal of the connector 3b from the fiber optic interface 1a.

[0074] One or more second protrusions 32b are provided on both the left and right sides of the base 33. For example, a pair of second protrusions 32b is provided on each side as shown in the figure, but it is not limited to this. In this way, by providing second protrusions 32b on both the left and right sides, the positional matching between the gripper 42 and the fixed base 30 can be improved when the gripper 42 abuts against the second protrusions 32b, and the pushing force of the gripper 42 on the fixed base 30 can be balanced from left to right, so as to prevent the fixed base 30 from deflecting relative to the gripper 42.

[0075] In this embodiment, the gripper 42 can move back and forth relative to the fixed base 30 between the first protrusion 32a and the second protrusion 32b. This avoids the gripper 42 from being affected by the frictional resistance of both the first and second protrusions 32a and 32b, preventing it from smoothly clamping or releasing the base 33. Furthermore, during fiber insertion and when the gripper 42 releases the base 33, it moves forward against the first protrusion 32a and separates from the second protrusion 32b, thus preventing the first and second protrusions 32a and 32b from simultaneously contacting the gripper 42 and generating significant friction. This ensures the fixed base 30 can move freely in a direction perpendicular to the insertion / removal direction, improving the adaptability of the fiber optic assembly 3 and the optical module 1 during fiber insertion.

[0076] Furthermore, in one embodiment, the drive mechanism further includes a slide rail 23, through which the driven seat 224 is movably connected to the driving seat 223 along the insertion / extraction direction. During the movement of the clamp 42 driving the fixed seat 30 along the fiber insertion direction, if the backward resistance of the fixed seat 30 to the clamp 42 suddenly increases, and during the movement of the clamp 42 driving the fixed seat 30 along the fiber extraction direction, if the forward resistance of the fixed seat 30 to the clamp 42 suddenly increases, the position between the driven seat 224 and the driving seat 223 will change accordingly, for example, by slightly moving between them along the insertion / extraction direction. Correspondingly, the aforementioned resistance change can be transmitted and reflected in the change of force between the driven seat 224 and the driving seat 223.

[0077] The insertion / removal device 100 also includes a sensing module 60 disposed between the active seat 223 and the driven seat 224. Specifically, the sensing module 60 can sense the aforementioned force changes or positional changes between the active seat 223 and the driven seat 224, so that the insertion / removal device 100 can accurately control the fiber insertion and / or fiber removal processes based on the sensing signals from the sensing module 60. For example, during fiber insertion, the gripper 42 drives the seat 33 forward. When the connector 3b of the fiber optic assembly 3 is inserted into place, the connector 3b experiences an increased backward resistance from the optical module 1. Through force transmission, this causes a sudden increase in the backward resistance of the fixed seat 30 against the gripper 42. The sensing module 60 can then generate a second sensing signal in response to this increased backward resistance, allowing the insertion / removal device 100 to accurately terminate the fiber insertion process.

[0078] Specifically, the sensing module 60 is a force sensor configured between the driven seat 224 and the driving seat 223, or it may be a distance sensor.

[0079] Furthermore, in one embodiment, the insertion / removal device 100 further includes a control module, which connects to and controls the drive member 21, the clamping drive member 41, and the pressing drive member 51, and connects to the sensing module 60 and controls the actions of the drive member 21, the clamping drive member 41, and the pressing drive member 51 according to the sensing signal of the sensing module 60, so as to realize the control of the insertion / removal process of the optical fiber assembly 3.

[0080] An embodiment of the present invention also provides a method for inserting and removing the optical fiber assembly 3. The method employs the aforementioned insertion and removal device 100 for inserting the optical fiber assembly 3 into or removing it from the slot. In the accompanying drawings, the slot is exemplified as the optical fiber interface 1a of the optical module 1. It is understood that, in addition to the optical fiber interface 1a of the optical module 1, the slot may also be implemented as other structures adapted to the insertion and removal of the optical fiber assembly 3.

[0081] The insertion and removal method provided by an embodiment of the present invention will be described in detail below, with reference to the specific structure of the insertion and removal device 100.

[0082] The insertion and removal method specifically includes a fiber optic insertion method, which includes the following steps:

[0083] The gripper 42 clamps the base 33 of the fixing seat 30 so that the connector 3b of the optical fiber assembly 3 installed on the base 33 is in the initial orientation.

[0084] The drive mechanism drives the clamping mechanism 40 to move from the starting position along the fiber insertion direction to the middle position, during which the gripper 42 keeps the clamping body 33 in place; the middle position is the position of the clamping mechanism 40 when the end of the connector 3b reaches the slot (e.g., the optical fiber interface 1a of the optical module 1).

[0085] The gripper 42 releases the seat 33, and the driving mechanism drives the clamping mechanism 40 to continue moving from the middle position along the fiber insertion direction to the target position where the fiber optic assembly 3 is inserted. During this period, the gripper 42 keeps the seat 33 released and pushes against the first protrusion 32a to drive the fixed seat 30 to move along the fiber insertion direction.

[0086] Thus, the insertion method provided in one embodiment allows the optical fiber assembly 3 to be flexibly and adaptively inserted into the optical module 1, solving the problem of damage and contamination of the coupling end face caused by hard insertion throughout the fiber insertion process in the prior art, and ensuring the product yield and reliability of the optical module; on the other hand, based on the cooperation between the gripper 42 and the fixing seat 30, the fixing seat 30 is driven forward by the gripping mechanism 40 during the fiber insertion process, with high degree of freedom of movement and simple overall structure.

[0087] In other words, the entire fiber insertion process in which the drive mechanism drives the clamping mechanism 40 to move from the starting position to the target position along the fiber insertion direction can be roughly divided into a first forward movement stage and a second forward movement stage:

[0088] In the first forward stage, the driving mechanism drives the clamping mechanism 40 to move from the starting position along the fiber insertion direction to the middle position, during which the gripper 42 keeps the clamping seat 33; in this way, the connector 3b is inserted into the optical fiber interface 1a of the optical module 1 at a preset initial angle / orientation, completing the initial insertion of the connector 3b and the optical fiber interface 1a, for example, so that the front end of the connector 3b just enters the guide port of the optical fiber interface 1a but has not yet been inserted into the coupling position.

[0089] In the second forward phase, the driving mechanism drives the clamping mechanism 40 to continue moving from the middle position along the fiber insertion direction to the target position. During this period, the gripper 42 keeps the seat 33 loose and pushes against the first protrusion 32a to drive the fixed seat 30 to move. In this way, while allowing the fixed seat 30 to move left and right and vertically, the fixed seat 30 is pushed forward until the connector 3b and the fiber optic interface 1a are inserted (that is, the connector 3b and the fiber optic interface 1a are inserted into place, and the fiber optic assembly 3 and the optical module 1 achieve optical coupling).

[0090] Furthermore, in one embodiment, the fiber insertion method further includes: using the sensing module 60 to collect a first incremental change in the force opposite to the fiber insertion direction to determine that the end of the connector 3b has reached the slot opening of the slot (e.g., the fiber optic interface 1a of the optical module 1).

[0091] The second incremental change of the force opposite to the insertion direction is collected by the sensing module 60 to determine whether the fiber optic assembly 3 is inserted in place.

[0092] In this way, by sensing whether the connector 3b is in contact with the optical fiber interface 1a and whether the optical fiber assembly 3 is inserted into place, the insertion status of the optical fiber assembly 3 can be accurately grasped. Regardless of the insertion tolerance between the optical fiber assembly 3 and any two optical modules 1 to be measured in the front-to-back direction, the first forward stage or / and the fiber insertion process can be ended in a timely and accurate manner. On the one hand, regarding the end point of the first forward stage, it can avoid the first forward stage ending too early, which would result in the connector 3b of the optical fiber assembly 3 not being effectively inserted into the guide port of the optical fiber interface 1a of the optical module 1, and it can also avoid the first forward stage ending too late, which would result in hard insertion and damage to the optical module. On the other hand, regarding the end point of the fiber insertion process, it can ensure that the optical fiber assembly 3 can achieve the best insertion position with the optical module 1, avoiding incomplete insertion and avoiding over-insertion which would cause impact damage to the coupling end face.

[0093] The fiber insertion method described above will now be explained in conjunction with the control module and the sensing module 60:

[0094] First, at the starting position, the control module controls the clamping drive 41 to drive the gripper 42 to clamp the seat 33, and controls the drive 21 to drive the transmission seat 22 to start moving from the starting position along the fiber insertion direction.

[0095] Next, when the connector 3b end of the fiber optic assembly 3 reaches the guide port of the fiber optic interface 1a of the optical module 1, the connector 3b is subjected to an increased backward resistance force from the optical module 1. Through the transmission of force, the sensing module 60 can sense the first incremental change of the force opposite to the insertion direction and generate a first sensing signal. Specifically, the first sensing signal can be expressed as the increase in force or the magnitude of the force exceeding a first threshold. At this time, the control module receives the first sensing signal from the sensing module 60 and determines that the intermediate position has been reached (i.e., it determines that the connector 3b end of the fiber optic assembly 3 reaches the guide port of the fiber optic interface 1a of the optical module 1), and then controls the clamping drive 41 to drive the jaw 42 to change from the state of clamping the seat 33 to the state of releasing the seat 33, that is, the first forward stage ends and the second forward stage begins.

[0096] Then, the control module controls the drive component 21 to drive the transmission seat 22 to continue moving along the fiber insertion direction;

[0097] Next, when the connector 3b of the fiber optic assembly 3 is inserted into place, the connector 3b is subjected to a further increase in the backward abutment force from the optical module 1. Through the transmission of force, the sensing module 60 can sense the second incremental change of the force opposite to the insertion direction and generate a second sensing signal. Specifically, the second sensing signal can be expressed as the increase in force or the magnitude of the force exceeding a second threshold. At this time, the control module receives the second sensing signal from the sensing module 60 and determines that the target position has been reached (i.e., the fiber optic assembly 3 is inserted into place), and then controls the drive unit 21 to stop driving the transmission seat 22 to continue forward, so as to end the insertion process.

[0098] Furthermore, the insertion and removal method specifically includes a fiber removal method, wherein during the process of the driving mechanism driving the clamping mechanism 40 to return from the target position to the starting position along the fiber removal direction, the gripper 42 removes the optical fiber assembly 3 by clamping the seat 33, or the gripper 33 removes the optical fiber assembly 3 by pushing against the second protrusion 32b to drive the fixing seat 30 to move along the fiber removal direction.

[0099] The fiber removal method preferably includes an unlocking step, which specifically involves the pressing member 52 pressing the latch 31b of the connector 3b of the fiber optic assembly 3 to unlock the connector 3b from the slot (e.g., the fiber optic interface 1a of the optical module 1), thereby facilitating the smooth removal of the connector 3b from the fiber optic assembly 3.

[0100] In other words, the fiber pulling method is applied during the fiber pulling process in which the drive mechanism drives the clamping mechanism 40 to move from the target position along the fiber pulling direction back to the starting position.

[0101] Specifically, based on the total displacement M of the transmission seat 22 along the fiber insertion direction during the fiber insertion process, the total displacement M of the transmission seat 22 along the fiber extraction direction during the fiber extraction process is controlled. That is, when the driving mechanism drives the clamping mechanism 40 to move from the target position along the fiber extraction direction to reach the total displacement M, it is considered to return to the starting position and end the fiber extraction process.

[0102] In addition, based on the above fiber pulling method, the fiber pulling process has a variety of specific implementation methods, which will be introduced below.

[0103] <The first implementation method of the fiber optic extraction process>

[0104] During the fiber removal process, the release drive 51 drives the pressing member 52 to hold the latch 31b of the fiber optic assembly 3 in place, and the gripper 42 always keeps the seat 33 clamped. In this way, pressing the latch 31b ensures that the fiber optic assembly 3 can be smoothly and easily removed from the optical module 1. At the same time, the gripper 42 always keeps the seat 33 clamped. On the one hand, it can ensure that the fixed seat 30 is stable and does not move when the pressing member 52 presses the latch 31b. On the other hand, it can maintain the fixed seat 30 at the preset starting angle after the fiber removal is completed, so that the insertion and removal device 100 can quickly and seamlessly enter the next round of insertion and removal process.

[0105] Understandably, in this first embodiment, at the target position, the control module controls the release drive 51 to drive the pressing member 52 to change from the state of releasing the latch 31b to the state of pressing the latch 31b, and at the same time, controls the clamping drive 41 to drive the gripper 42 to change from the state of releasing the seat 33 to the state of clamping the seat 33; after returning to the starting position, the control module controls the release drive 51 to drive the pressing member 52 to return to the state of releasing the latch 31b, and controls the clamping drive 41 to drive the gripper 42 to maintain the state of clamping the seat 33, so as to directly enter the next round of insertion and removal process.

[0106] <Second method of implementing the fiber optic extraction process>

[0107] During the fiber removal process, the release drive 51 drives the pressing member 52 to hold the latch 31b of the fiber optic assembly 3 in place, and the gripper 42 remains open to the seat 33 and pushes against the second protrusion 32b to move the fixing seat 30. In this way, pressing the latch 31b ensures that the fiber optic assembly 3 can be smoothly and easily removed from the optical module 1.

[0108] Understandably, in this second embodiment, at the target position, the control module controls the release drive 51 to drive the pressing member 52 to change from the state of releasing the latch 31b to the state of pressing the latch 31b, while controlling the clamping drive 41 to drive the gripper 42 to keep the seat body 33 in the state of being released; after returning to the starting position, the control module controls the release drive 51 to drive the pressing member 52 to return to the state of releasing the latch 31b, and after entering the next round of insertion and removal process, it controls the clamping drive 41 to drive the gripper 42 to change from the state of being released ...

[0109] Furthermore, corresponding to the fiber extraction process of this second embodiment, in the first forward stage of the fiber insertion process, the gripper 42 abuts against the second protrusion 32b and separates from the first protrusion 32a; while in the second forward stage, during a short stroke starting from the intermediate position, the gripper 42 moves forward relative to the fixed base 30, so as to change from a state of abutting against the second protrusion 32b to a state of abutting against the first protrusion 32a.

[0110]

[0111] In this implementation, the fiber pulling process is divided into a first retraction stage and a second retraction stage:

[0112] In the first retraction phase, the drive mechanism drives the clamping mechanism 40 to move from the target position along the fiber pulling direction to the second intermediate position. During this period, the gripper 42 remains released from the seat 33, and the pressing member 52 remains released from the buckle 31b. The second intermediate position is the position of the clamping mechanism 40 when the gripper 42 abuts against the second protrusion 32b.

[0113] In the second retraction phase, the drive mechanism drives the clamping mechanism 40 to continue returning from the second intermediate position to the starting position along the fiber pulling direction. During this period, the drive member 51 is released to drive the pressing member 52 to keep pressing the buckle 31b, and the gripper 42 keeps clamping the seat 33.

[0114] Thus, based on the setting of the second protrusion 32b, the relative position between the gripper 42 and the fixed seat 30 in the insertion and extraction direction can be assisted, thereby facilitating the spatial positioning of the fixed seat 30 and avoiding the increase in control difficulty of the drive mechanism due to the change in position between the gripper 42 and the fixed seat 22.

[0115] Furthermore, in one embodiment, during the first retraction phase, the sensor module 60 collects a third incremental change in the force opposite to the fiber pulling direction to determine that the gripper 42 is abutting against the second protrusion 32b, thereby ending the first retraction phase and entering the second retraction phase. This timely and accurate timing of the clamping drive 41 and the releasing drive 51 facilitates efficient and accurate control, avoiding premature end of the first retraction phase—which would cause misalignment of the fixing seat 30 when the pressing member 52 presses the latch 31b—and also avoiding premature end of the first retraction phase—which would result in forcibly pulling the fiber optic assembly 3 backward before the latch 31b has been released.

[0116] The fiber unplugging process of this third implementation method will be described below, in conjunction with the control module and the sensing module 60:

[0117] At the target position, the gripper 42 holds the released seat 33, and the control module controls the drive unit 21 to drive the transmission seat 22 to move backward from the target position;

[0118] Next, when the gripper 42 abuts against the second protrusion 32b, the connector 3b experiences an increased forward force from the optical module 1. Through force transmission, the sensing module 60 can sense the third incremental change of the force opposite to the fiber pulling direction and generate a third sensing signal. Specifically, the third sensing signal can be expressed as the increase in force or the magnitude of the force exceeding a third threshold. At this time, the control module receives the third sensing signal from the sensing module 60 and determines that the second intermediate position has been reached (i.e., the gripper 42 abuts against the second protrusion 32b). Then, it controls the clamping drive 41 to drive the gripper 42 from the state of releasing the seat 33 to the state of clamping the seat 33, and controls the release drive 52 to drive the pressing member 52 from the state of releasing the buckle 31b to the state of pressing the buckle 31b, that is, the first retraction stage ends and the second retraction stage begins.

[0119] Then, the control module controls the drive unit 21 to drive the transmission seat 22 to continue moving along the fiber pulling direction until the transmission seat 22 reaches a total displacement M along the fiber pulling direction, thus ending the fiber pulling process.

[0120] In summary, compared with the prior art, this embodiment has at least the following beneficial effects: The insertion and removal device 100, with its simple structure, enables the optical fiber assembly 3 to be inserted in a free state with relative left and right and vertical movement, with a high degree of freedom of movement. This solves the problem of damage and contamination of the coupling end face caused by the hard insertion process throughout the fiber insertion process in the prior art, and ensures the product yield and reliability of the optical module.

[0121] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
