Description

Technical Field

[0001] This invention belongs to the field of optical communication, and more specifically, relates to a fully automated coupling device and method for glass-encapsulated micro-optical devices. Background Technology

[0002] In the current micro-optical device manufacturing industry, coupling and packaging is one of the key processes, and its coupling and packaging accuracy directly determines the optical performance of the device. Traditional micro-optical device coupling methods mostly rely on manual operation or semi-automated equipment.

[0003] Manual coupling relies primarily on operators' experience to adjust the position of micro-optical devices and determine the optimal coupling position by observing optical performance indicators (such as optical power and insertion loss). This method has significant drawbacks: firstly, the accuracy of manual operation is greatly affected by subjective factors such as operator experience and fatigue, making it difficult to guarantee stable coupling accuracy and prone to coupling deviations, leading to unstable device performance; secondly, manual coupling is extremely inefficient, difficult to package, and cannot meet the needs of large-scale mass production. Especially as the size of micro-optical devices continues to shrink and the precision requirements continue to increase, manual coupling is gradually becoming unsuitable for industry development.

[0004] Although semi-automated coupling equipment reduces human intervention to some extent, the dispensing and encapsulation operation between the glass tube and the collimating lens is still done manually. The degree of automation is not high, the dispensing and encapsulation requires a high level of human experience, the training cycle is long, and the consistency of manual dispensing and encapsulation is poor, resulting in large fluctuations in product quality.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

Detailed Implementation

[0075] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0076] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as openly inclusive, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiment," "example," "specific example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples; that is, although they may be incorporated into embodiments or examples using the above terms for reasons such as order and position, it does not limit them to be incorporated in combination by a single embodiment or example.

[0077] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more. Furthermore, for example, the description may use the prefix "A" or "B" to describe the same type of nouns as two independent entities. In this case, the corresponding features defined with "A" and "B" are used only to distinguish between similar entities and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0078] In the description of this invention, the terms "A and / or B" are used to represent specific features, and the corresponding expressions include the following three combinations: only A, only B, and a combination of A and B.

[0079] As used in this invention, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from a particular value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity, i.e., the limitations of the measurement system.

[0080] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0081] Example 1:

[0082] This embodiment provides a fully automated coupling device for glass-encapsulated micro-optical devices, such as... Figure 1 and Figure 2 As shown, it includes: a first clamping mechanism 2, a second clamping mechanism 3, a glue transfer mechanism 4, and a glue dispensing mechanism 5, all mounted on the vibration damping table 1, wherein:

[0083] The first clamping mechanism 2 and the second clamping mechanism 3 are used to adjust the positions of different fiber collimators 7 respectively to confirm the reference debugging position with the least insertion loss; and to insert the two fiber collimators 7 into the two ends of the glass tube 8 respectively.

[0084] In this embodiment, the first clamping mechanism 2 and the second clamping mechanism 3 are arranged opposite to each other on the vibration damping table 1. When both the first clamping mechanism 2 and the second clamping mechanism 3 clamp an optical fiber collimator 7, the first clamping mechanism 2 and the second clamping mechanism 3 are equipped with adjustment slides with different adjustment dimensions. By adjusting the different slides, the position and angle of the clamps on the first clamping mechanism 2 and the second clamping mechanism 3 can be adjusted so that the two optical fiber collimators 7 can be positioned relative to each other and coupled. During the coupling process, the movement position of the first clamping mechanism 2 and the second clamping mechanism 3 can be traversed, and optical performance indicators such as optical power or insertion loss can be monitored at the same time to determine the optimal position of the first clamping mechanism 2 and the second clamping mechanism 3 and record the optimal position.

[0085] Furthermore, since the two fiber optic collimators 7 need to be encapsulated through a glass tube 8, which is cylindrical and has a sleeve structure, the two fiber optic collimators 7 are inserted into the two ends of the glass tube 8 respectively, and optical coupling is performed inside the glass tube 8. After the coupling requirements are met, adhesive is applied to both ends of the glass tube 8, allowing the adhesive to enter between the fiber optic collimators 7 and the glass tube 8, and ensuring that the adhesive is evenly distributed there. Finally, the adhesive is cured, thus completing the encapsulation between the two fiber optic collimators 7 and the glass tube 8. In actual adhesive application, the dispensing parameters need to be controlled for the coupling encapsulation of different models of fiber optic collimators 7 and glass tubes 8. Furthermore, when the adhesive is applied between the fiber optic collimators 7 and the glass tube 8, while ensuring that the adhesive is evenly distributed around the periphery of the fiber optic collimators 7, it is also necessary to ensure that the adhesive is distributed along a specified length in the axial direction of the fiber optic collimators 7. Therefore, this embodiment also involves the following design:

[0086] The dispensing mechanism 5 is used to dispense adhesive to both ends of the glass tube 8. The adhesive transfer mechanism 4 is used to clamp the glass tube 8 and control the glass tube 8 to rotate. It works in conjunction with the first clamping mechanism 2 and the second clamping mechanism 3 to clamp the corresponding optical fiber collimator 7 and insert and withdraw it inside the glass tube 8, so as to achieve uniform distribution of adhesive between the optical fiber collimator 7 and the glass tube 8. The first clamping mechanism 2 and the second clamping mechanism 3 are used to readjust the position of the corresponding optical fiber collimator 7 so that the optical fiber collimator 7 is in the reference adjustment position before the adhesive is cured.

[0087] In this embodiment, the dispensing mechanism 5 has slides in different directions. By adjusting these slides, the dispensing port of the dispensing mechanism 5 is moved to the port position of the glass opening, and dispensing is performed at the corresponding position. The transfer mechanism 4 has slides in different directions. By adjusting these slides, the upper end of the transfer mechanism 4 is moved to the position of the glass tube 8, and the glass tube 8 is clamped and limited.

[0088] Since dispensing can only apply glue to a fixed area and cannot directly and evenly coat the glass tube 8 and the periphery of the fiber optic collimator 7, nor can it distribute the glue evenly over a specified length, a glue transfer mechanism 4 clamps the glass tube 8 and rotates it. This allows the glue to spread and distribute along the inner wall of the glass tube 8 and around the periphery of the fiber optic collimator 7 as the glass tube 8 rotates. Simultaneously, while keeping the fiber optic collimator 7 inserted into the glass tube 8, the slides on the first clamping mechanism 2 and the second clamping mechanism 3 are adjusted, causing the fiber optic collimator 7 to reciprocate in and out along the axial direction within the glass tube 8. The glue extends along the axial direction under the action of this insertion and withdrawal, achieving the required glue distribution. Figure 2 As shown, Figure 2 The direction of the middle arrow indicates the direction of rotation of glass tube 8. It should be noted that... Figure 2 The middle glass tube 8 needs to be clamped by the transfer mechanism 4 in order to be driven to rotate. Figure 2 This is for illustrative purposes only. Figure 2 When the glass tube 8 and the transfer mechanism 4 are not in contact, the glass tube 8 cannot rotate, and the direction of movement of the fiber optic collimator 7 is also not determined.

[0089] Once the adhesive coating meets the requirements, the two fiber optic collimators 7 are restored to their optimal positions by adjusting the first clamping mechanism 2 and the second clamping mechanism 3 according to the previously recorded optimal positions. This allows the two fiber optic collimators 7 to be coupled within the glass tube 8. Finally, the adhesive is cured to complete the encapsulation.

[0090] Through the above-described device structure, the optical path coupling, dispensing, and adhesive distribution in the glass encapsulation of the fiber collimator 7 can all be automated through the corresponding module device, eliminating the need for manual coupling and encapsulation, thus greatly improving the efficiency of coupling and encapsulation and the accuracy of the operation process.

[0091] In this embodiment, all X-axis directions are Figure 1 The direction of the X-axis in the coordinate system is [missing information], and the directions of all Y-axis are [missing information]. Figure 1 The direction of the Y-axis in the coordinate system is as follows: All Z-axis directions are... Figure 1 The direction of the Z-axis in the medium coordinate system.

[0092] Furthermore, in this embodiment, since both ends of the glass tube 8 need to be glued, and considering the available installation space on the vibration damping table 1, this embodiment also involves the following design: Figure 3 As shown, the dispensing mechanism 5 specifically includes: a support frame 51, a dispensing table 52, a first dispensing assembly 53, and a second dispensing assembly 54. The support frame 51 is mounted on the shock-absorbing table 1 and has a first slide rail. The dispensing table 52 is slidably mounted on the first slide rail. Both the first dispensing assembly 53 and the second dispensing assembly 54 are mounted on the dispensing table 52. The dispensing table 52 slides along the extension direction of the first slide rail to drive the first dispensing assembly 53 and the second dispensing assembly 54 to slide synchronously. Both the first dispensing assembly 53 and the second dispensing assembly 54 have dispensing heads. By adjusting the first dispensing assembly 53 and the second dispensing assembly 54, the corresponding dispensing heads are adjusted to their respective positions. The two dispensing heads are used to dispense adhesive to both ends of the glass tube 8.

[0093] In this embodiment, since the dispensing needs to be performed from above the glass tube 8 and the fiber optic collimator 7, the dispensing outlet of the dispensing mechanism 5 needs to be set relatively high. Therefore, in this embodiment, a support frame 51 is set on the vibration damping table 1, and the dispensing table 52, which is equipped with the first dispensing component 53 and the second dispensing component 54, is slidably placed on the first slide rail of the support frame 51. The support frame 51 directly raises the dispensing table 52, which is equipped with the first dispensing component 53 and the second dispensing component 54, to a position higher than the first clamping mechanism 2 and the second clamping mechanism 3, so that its height meets the dispensing requirements. In this embodiment, the first slide rail along... Figure 1 The dispensing stage 52 extends along the X-axis to allow it to move along the X-axis. This movement of the dispensing stage 52 moves the first dispensing assembly 53 and the second dispensing assembly 54 to corresponding positions above the glass tube 8.

[0094] The first dispensing assembly 53 and the second dispensing assembly 54 are each equipped with a multi-dimensional adjustment slide for individually and precisely controlling the position of the dispensing port, so that the position of the dispensing port and the glass tube 8 port are accurately aligned.

[0095] Specifically, since both the first dispensing assembly 53 and the second dispensing assembly 54 are equipped with multi-dimensional adjustment slides for precise control of the dispensing nozzle position, this embodiment involves the following design for the first dispensing assembly 53: (e.g.) Figure 4 As shown, the first dispensing assembly 53 includes: a first base 531, a first Y-axis slide 532, a first X-axis slide 533, and a first Z-axis slide 534, wherein: the first base 531 is disposed on the dispensing table 52, the first base 531 is provided with a first Y-axis slide rail, and the first Y-axis slide 532 is slidably disposed on the first Y-axis slide rail; the first Y-axis slide 532 is provided with a first X-axis slide rail, and the first X-axis slide 533 is slidably disposed on the first X-axis slide rail; the first X-axis slide 533 is provided with a first Z-axis slide rail, and the first Z-axis slide 534 is slidably disposed on the first Z-axis slide rail; the dispensing head is disposed on the first Z-axis slide 534, and the position of the dispensing head in the X-axis, Y-axis, and Z-axis directions can be adjusted by adjusting the first Y-axis slide 532, the first X-axis slide 533, and the first Z-axis slide 534.

[0096] In this embodiment, the first Y-axis slide rail follows the... Figure 1 Extending along the Y-axis direction on the horizontal plane, the first Y-axis slide 532 is used to slide along the first Y-axis slide rail, and the first X-axis slide rail extends along... Figure 1 Extending along the X-axis direction on the horizontal plane, the first X-axis slide 533 is used to slide along the first X-axis slide rail. The position of the dispensing head of the first dispensing assembly 53 on the horizontal plane is adjusted by the first X-axis slide 533 and the first Y-axis slide 532. The first Z-axis slide rail extends along the X-axis direction on the horizontal plane. Figure 1 Extending along the Z-axis, the first Z-axis slide 534 is used to slide along the first Z-axis slide rail to adjust the position of the dispensing head in the vertical direction. This structure enables precise position control of the dispensing head of the first dispensing assembly 53. Figure 4 The middle arrow indicates the direction in which the corresponding slide can slide.

[0097] In this embodiment, the second dispensing component 54 and the first dispensing component 53 are mirror images of each other. The structural details of the second dispensing component 54 can be referred to the first dispensing component 53, and will not be described in detail here.

[0098] In this embodiment, all X-axis directions are Figure 1 The direction of the X-axis in the coordinate system is [missing information], and the directions of all Y-axis are [missing information]. Figure 1 The direction of the Y-axis in the coordinate system is as follows: All Z-axis directions are... Figure 1 The direction of the Z-axis in the medium coordinate system.

[0099] Furthermore, considering that after the subsequent dispensing is completed and the adhesive distribution and the coupling of the fiber collimator 7 meet the requirements, the adhesive needs to be cured to complete the encapsulation. Therefore, this embodiment also involves the following design: Figure 5 As shown, the dispensing mechanism 5 further includes a transition plate 55 and a UV curing module 56, wherein: the transition plate 55 is slidably disposed on the first slide rail, the UV curing module 56 and the dispensing stage 52 are both disposed on the transition plate 55, and the UV curing module 56 and the dispensing stage 52 are spaced apart by a first preset distance; when the adhesive between the fiber collimator 7 and the glass tube 8 is evenly distributed, and the two fiber collimators 7 are coupled in the glass tube 8, the position of the UV curing module 56 on the first slide rail is adjusted to make the positions of the UV curing module 56 and the glass tube 8 correspond, and the UV curing module 56 is used to cure the adhesive between the glass tube 8 and the fiber collimator 7.

[0100] In this embodiment, since the UV curing module 56 needs to be moved above the glass tube 8 and the fiber collimator 7 when curing the adhesive, the UV curing module 56 also needs to be moved and adjusted in the X-axis direction. To save space, the UV curing module 56 also uses the first slide rail on the support frame 51 for movement in the X-axis direction. However, since both the UV curing module 56 and the dispensing stage 52 occupy a relatively large space, if they could both slide independently on the first slide rail, they might collide and be damaged. Considering that the UV curing module 56 and the dispensing stage 52 are used at completely different times, the UV curing module 56 is only needed to cure the adhesive after dispensing is complete. Simultaneous interaction with the location of the glass tube 8 is required. Therefore, in this embodiment, both the UV curing module 56 and the dispensing stage 52 are fixedly mounted on the transition plate 55, with a first preset distance between them. The transition plate 55 drives the UV curing module 56 and the dispensing stage 52 to move together on the first slide rail, preventing them from moving independently and avoiding collisions or interference. When dispensing is required, the transition plate 55 slides on the first slide rail to move the dispensing stage 52 above the glass tube 8. When adhesive curing is required, the transition plate 55 slides on the first slide rail to move the UV curing module 56 above the glass tube 8. In this embodiment, the first preset distance is set by those skilled in the art based on actual conditions.

[0101] Furthermore, in this embodiment, since the fiber optic collimator 7 needs to be coupled and docked with the glass tube 8, the first clamping mechanism 2 and the second clamping mechanism 3 used to hold the fiber optic collimator 7 need to be able to drive the fiber optic collimator 7 to adjust its position and state in multiple dimensions and directions while holding the fiber optic collimator 7, so as to meet the operation in the coupling and docking process. Therefore, this embodiment also involves the following design.

[0102] like Figure 6 As shown, the first clamping mechanism 2 includes: a second base 21, a manually adjustable slide 22, a second X-axis slide 23, a second Y-axis slide 24, a second Z-axis slide 25, a second vertical axis rotating member 26, a second horizontal axis rotating member 27, and a second clamp 28. The second base 21 is mounted on the shock-absorbing table 1, and a second adjusting slide rail is mounted on the second base 21. The manually adjustable slide 22 is slidably mounted on the second adjusting slide rail. The manually adjustable slide 22 is mounted on the second X-axis slide rail, and the second X-axis slide 23 is slidably mounted on the second X-axis slide rail. The second X-axis slide 23 is mounted on the second Y-axis slide rail, and the second Y-axis slide 25 is slidably mounted on the second X-axis slide rail. A second Y-axis slide rail; a second Z-axis slide rail is provided on the second Y-axis slide table 24, and a second Z-axis slide table 25 is slidably disposed on the second Z-axis slide rail; a first arc surface is provided on the second Z-axis slide table 25, and a vertical axial arc guide rail is provided on the first arc surface, and a second vertical axial rotating member 26 is slidably disposed on the vertical axial arc guide rail; a second arc surface is provided on the second vertical axial rotating member 26, and a horizontal axial arc guide rail is provided on the second arc surface, and a second horizontal axial rotating member 27 is slidably disposed on the horizontal axial arc guide rail; a second clamp 28 is disposed on the second horizontal axial rotating member 27 and is used to clamp the corresponding fiber collimator 7.

[0103] In this embodiment, the second X-axis slide 23 is used to adjust the position of the second clamp 28 in the X-axis direction, the second Y-axis slide 24 is used to adjust the position of the second clamp 28 in the Y-axis direction, and the second Z-axis slide 25 is used to adjust the position of the second clamp 28 in the Z-axis direction. The spatial position of the second clamp 28 is adjusted by the second X-axis slide 23, the second Y-axis slide 24, and the second Z-axis slide 25. The second vertical axis rotating member 26 and the second horizontal axis rotating member 27 are used to adjust the tilt angle of the second clamp 28 in different directions to meet the conditions for coupling debugging. Figure 6 The arrows indicate the direction of movement adjustment for each slide at the end of the text.

[0104] In this embodiment, the second clamping mechanism 3 can be a mirror image of the first clamping mechanism 2, with the same structure. Alternatively, the second clamping mechanism 3 can include an X-axis slide, a Y-axis slide, and a Z-axis slide to control the spatial position of the clamps on the second clamping mechanism 3. No additional structure for adjusting the angle rotation of the clamps is needed because the first clamping mechanism 2 already includes a second vertical axis rotating member 26 and a second horizontal axis rotating member 27, which can be used to adjust the tilt angle of the fiber optic collimator 7 on the second clamp 28. Therefore, by unilaterally adjusting the tilt angle of the fiber optic collimator 7 on the first clamping mechanism 2, the different fiber optic collimators 7 on both sides can be coupled. Based on the above description, the specific structure of the second clamping mechanism 3 can be referenced from the first clamping mechanism 2, and will not be elaborated further here.

[0105] Furthermore, in this embodiment, the adhesive transfer mechanism 4 needs to clamp and rotate the glass tube 8 to evenly distribute the adhesive inside the glass tube 8. Therefore, the adhesive transfer mechanism 4 in this embodiment involves the following design: Figure 7 As shown, the transfer mechanism 4 includes: a third base 41, a horizontal slide 42, a vertical telescopic cylinder 43, and a rotating clamping assembly 44. The third base 41 is mounted on the shock-absorbing table 1. The horizontal slide 42 is slidably mounted on the third base 41 along the Y-axis. A third adjusting slide rail extending along the Y-axis is provided on the third base 41, and the horizontal slide 42 is slidably mounted on the third adjusting slide rail. The vertical telescopic cylinder 43 is mounted on the side wall of the horizontal slide 42, and the rotating clamping assembly 44 is mounted on the vertical telescopic cylinder 43. The vertical telescopic cylinder 43 drives the rotating clamping assembly 44 to move vertically. The rotating clamping assembly 44 clamps and limits the glass tube 8, and adjusts the axial rotation of the clamped and limited glass tube 8.

[0106] In this embodiment, the transfer mechanism 4 is positioned between the first clamping mechanism 2 and the second clamping mechanism 3. The lower end of the clamps extending from the first clamping mechanism 2 and the second clamping mechanism 3 is the lower end of the glass tube 8. When the glass tube 8 needs to be rotated, the rotating clamping assembly 44 needs to be moved to the position of the glass tube 8 to clamp and rotate it. Since the transfer mechanism 4 is already located at the lower end of the glass tube 8, the rotating clamping assembly 44 on the transfer mechanism 4 does not need to move in the X-axis direction. In this embodiment, the third adjusting slide rail extends along the Y-axis direction. The horizontal slide table 42 slides on the third adjusting slide rail, causing the rotating clamping assembly 44 to slide in the Y-axis direction, allowing the rotating clamping assembly 44 to accurately move to the lower end of the glass tube 8. The vertical telescopic cylinder 43 is used to drive the rotating clamping assembly 44 to move vertically, so that the upper end of the rotating clamping assembly 44 reaches the vertical height position of the glass tube 8, clamps the glass tube 8, and causes it to rotate. Figure 7 The arrows in the diagram indicate the adjustment directions of the horizontal slide 42 and the vertical telescopic cylinder 43.

[0107] Furthermore, in this embodiment, the rotating clamping assembly 44 is used to clamp and rotate the glass tube 8, therefore the rotating clamping assembly 44 involves the following design: Figure 8 As shown, the rotating clamping assembly 44 includes: a support plate 441, a pushing cylinder 442, a pushing member 443, a first clamping piece 444, a second clamping piece 445, a first pulley 446, and a second pulley 447, wherein: the support plate 441 is disposed on the vertical telescopic cylinder 43; the first clamping piece 444 and the second clamping piece 445 are both slidably disposed on the support plate 441 along the X-axis direction, wherein the support plate 441 is provided with a transverse guide rail, the first clamping piece 444 and the second clamping piece 445 are both slidably disposed on the transverse guide rail, the first pulley 446 is disposed on the upper end of the first clamping piece 444, and the second pulley 447 is disposed on the upper end of the second clamping piece 445.

[0108] The pushing cylinder 442 is disposed on the support plate 441 and located below the first clamping piece 444 and the second clamping piece 445; the pushing member 443 is disposed on the pushing cylinder 442, and the pushing cylinder 442 is used to push the pushing member 443 vertically.

[0109] The first clamping piece 444 and the second clamping piece 445 are each provided with a guide shaft 453. The pusher 443 is provided with two guide grooves 454. The guide shaft 453 is slidably disposed in the corresponding guide groove 454. When the pusher 443 is pushed in the vertical direction, the guide shaft 453 slides along the guide groove 454 to drive the first clamping piece 444 and the second clamping piece 445 to slide on the support plate 441, thereby realizing the approach and distance between the first clamping piece 444 and the second clamping piece 445.

[0110] When the first clamping piece 444 and the second clamping piece 445 approach each other, the first pulley 446 and the second pulley 447 clamp the glass tube 8, and the rotation of the first pulley 446 and the second pulley 447 drives the glass tube 8 to rotate.

[0111] In this embodiment, the lower half of the first clamping piece 444 and the lower half of the second clamping piece 445 are both slidably connected to the transverse guide rail on the support plate 441. The transverse guide rail is parallel to the horizontal direction. The upper half of the first clamping piece 444 and the upper half of the second clamping piece 445 extend out of the upper end of the support plate 441. There is always a gap between the first clamping piece 444 and the second clamping piece 445. By adjusting the gap between the first clamping piece 444 and the second clamping piece 445, the glass tube 8 can be clamped or released.

[0112] Correspondingly, in this embodiment, the guide shaft 453 is disposed on the lower half of the first clamping piece 444 and the second clamping piece 445, and is located on the side of the first clamping piece 444 and the second clamping piece 445 facing away from the support plate 441; the pusher 443 includes a bearing part and two docking parts, which are respectively disposed at both ends of the bearing part. Each docking part is provided with a guide groove 454, which is inclined downward from the outer side to the inner side of the docking part. The lower end of the bearing part is docked with the push cylinder 442, and the push cylinder 442 drives the entire pusher 443 to move up and down in the vertical direction; the guide shaft 453 of the first clamping piece 444 and the guide shaft 453 of the second clamping piece 445 are respectively slidably engaged in the guide grooves 454 at both ends of the pusher 443; when the pusher pushes... When the pusher moves upward under the action of the pusher cylinder 442, the guide shaft 453 slides obliquely downward along the guide groove 454, and the first clamping piece 444 and the second clamping piece 445 slide laterally inward along the horizontal guide rail, thereby reducing the distance between the first clamping piece 444 and the second clamping piece 445. The glass tube 8 is clamped and limited by the first pulley 446 and the second pulley 447. When the pusher moves downward under the action of the pusher cylinder 442, the guide shaft 453 slides obliquely upward along the guide groove 454, and the first clamping piece 444 and the second clamping piece 445 slide laterally outward along the horizontal guide rail, thereby increasing the distance between the first clamping piece 444 and the second clamping piece 445. The clamping of the glass tube 8 by the first pulley 446 and the second pulley 447 is released. The first pulley 446 and the second pulley 447 can be rotated through the transmission relationship of the motor 452 and other pulley groups, thereby driving the glass tube 8 to rotate. Figure 8 The direction of the arrow in the diagram indicates the adjustment direction of the corresponding component.

[0113] Furthermore, regarding the driving of the first pulley 446 and the second pulley 447, this embodiment provides a feasible implementation structure as follows: Figure 9As shown, the rotating clamping assembly 44 further includes: a third pulley 448, a fourth pulley 449, a fifth pulley 450, and a sixth pulley 451, and a motor 452, wherein: the third pulley 448 is disposed on the first clamping plate 444 and located below the first pulley 446; the fourth pulley 449 is disposed on the second clamping plate 445 and located below the second pulley 447; the fifth pulley 450 and the sixth pulley 451 are both disposed on the support plate 441, and the fifth pulley 450 and the sixth pulley 451 are located between the first clamping plate 444 and the second clamping plate 446. Between 5, the fifth pulley 450 is located above the sixth pulley 451; the first pulley 446, the second pulley 447, the third pulley 448, the fourth pulley 449, the fifth pulley 450, and the sixth pulley 451 are connected by a belt; a motor 452 is also provided on the back of the support plate 441, and the motor 452 cooperates with the sixth pulley 451. The motor 452 is used to drive the sixth pulley 451 to rotate, which in turn drives the first pulley 446 and the second pulley 447 to rotate through the third pulley 448, the fourth pulley 449, and the fifth pulley 450.

[0114] Furthermore, in this embodiment, to ensure the entire coupling and encapsulation process is fully automated, after a set of glass tubes 8 and fiber collimators 7 are coupled and encapsulated, a corresponding device module is needed to call different glass tubes 8 to perform the coupling and encapsulation of the next set of glass tubes 8 and fiber collimators 7. Therefore, this embodiment also involves the following design: Figure 10 As shown, the fully automated coupling device for glass-encapsulated micro-optical devices further includes a third clamping mechanism 6, wherein: the third clamping mechanism 6 includes a fourth base 61, a fourth X-axis slide 62, a fourth Y-axis slide 63, a fourth Z-axis slide 64, and a fourth clamp 65; the fourth base 61 is disposed on the vibration damping table 1, and a fourth X-axis slide rail is disposed on the fourth base 61; the fourth X-axis slide 62 is slidably disposed on the fourth X-axis slide rail; a fourth Y-axis slide rail is disposed on the fourth X-axis slide 62, and a fourth Y-axis slide 63 is slidably disposed on the fourth Y-axis slide rail; a fourth Z-axis slide rail is disposed on the fourth Y-axis slide 63, and a fourth Z-axis slide 64 is slidably disposed on the fourth Z-axis slide rail; the fourth clamp 65 is disposed on the fourth Z-axis slide 64, and the fourth clamp 65 is used to clamp the glass tube 8.

[0115] In this embodiment, the fourth X-axis slide 62 is used to adjust the position of the fourth clamp 65 in the X-axis direction, the fourth Y-axis slide 63 is used to adjust the position of the fourth clamp 65 in the Y-axis direction, and the fourth Z-axis slide 64 is used to adjust the position of the fourth clamp 65 in the Z-axis direction. The spatial position of the fourth clamp 65 is adjusted by the fourth X-axis slide 62, the fourth Y-axis slide 63, and the fourth Z-axis slide 64, thereby moving the glass tube 8 on the fourth clamp 65 to the designated position. Figure 10 The arrows in the diagram indicate the direction of adjustment and movement of the corresponding slide.

[0116] Furthermore, in this embodiment, a device storage module can be provided on the outside of the second clamping mechanism 3 for storing glass tubes 8. The upper end of the device storage module is the outlet. The fourth clamp 65 clamps the glass tube 8 from the outlet and moves the glass tube 8 between the two fiber collimators 7. It is worth mentioning that after the glass tube 8 at the upper end of the outlet is clamped away, the next glass tube 8 inside the device storage module will move sequentially to the outlet for subsequent clamping by the fourth clamp 65. Structures that can achieve the above effect are relatively mature on the market and will not be described in detail here.

[0117] Furthermore, in this embodiment, as Figure 11 As shown, the vibration damping table 1 is also equipped with an upper vision industrial camera 9 and a lower vision industrial camera 10. The upper vision industrial camera 9 is used to observe from above the glass tube 8 and the fiber optic collimator 7, and the lower vision industrial camera 10 is used to observe from the horizontal direction of the glass tube 8 and the fiber optic collimator 7.

[0118] Example 2:

[0119] This embodiment provides a fully automated coupling method for glass-encapsulated micro-optical devices based on Embodiment 1, for application in the aforementioned fully automated coupling device for glass-encapsulated micro-optical devices, such as... Figure 12 As shown, it includes:

[0120] In step 101, the two fiber collimators 7 are clamped onto the first clamping mechanism 2 and the second clamping mechanism 3, respectively.

[0121] In step 102, all debugging positions of the first clamping mechanism 2 and the second clamping mechanism 3 are traversed, and the debugging position corresponding to the minimum insertion loss between the two fiber collimators 7 is recorded as a reference debugging position.

[0122] It should be noted that before debugging the first clamping mechanism 2 and the second clamping mechanism 3, the insertion loss threshold should be set and the current environmental parameters should be recorded. During the debugging process, the minimum insertion loss obtained must be less than the insertion loss threshold. If the minimum insertion loss is greater than or equal to the minimum insertion loss, the debugging process needs to continue. The insertion loss threshold shall be set by those skilled in the art based on the actual situation.

[0123] In step 103, the glass tube 8 is placed between the two fiber optic collimators 7, and the two fiber optic collimators 7 are inserted at both ends of the glass tube 8 respectively.

[0124] In step 104, the dispensing mechanism 5 is adjusted to dispense adhesive to both ends of the glass tube 8, the transfer mechanism 4 is adjusted to clamp the glass tube 8 and control the glass tube 8 to rotate, and the first clamping mechanism 2 and the second clamping mechanism 3 are used to clamp the corresponding optical fiber collimator 7 and insert and remove it in the glass tube 8 to achieve uniform distribution of adhesive between the optical fiber collimator 7 and the glass tube 8.

[0125] In this embodiment, the positions of the first dispensing assembly 53 and the second dispensing assembly 54 are adjusted to correspond with the positions of both ends of the glass tube 8 for dispensing. After dispensing, the slide on the dispensing transfer mechanism 4 is adjusted to position the glass tube 8 between the first clamping plate 444 and the second clamping plate 445. The push cylinder is adjusted to lift the push plate, reducing the gap between the first clamping plate 444 and the second clamping plate 445, allowing the first pulley 446 and the second pulley 447 to clamp and limit the glass tube 8. The motor 452 is then turned on to drive the first pulley 446 and the second pulley 447 to rotate, causing the glass tube 8 to rotate. It should be noted that before dispensing, the dispensing parameters, such as the dispensing volume, need to be set using previously recorded current environmental parameters.

[0126] The distribution of the adhesive and whether the distribution length meets industrial requirements are monitored in real time by the upper vision industrial camera 9 and the lower vision industrial camera 10. If they meet the requirements, the activities of the adhesive transfer mechanism 4, the first clamping mechanism 2 and the second clamping mechanism 3 are stopped.

[0127] In step 105, the first clamping mechanism 2 and the second clamping mechanism 3 adjust the position of the corresponding fiber optic collimator 7 according to the reference adjustment position, so that the fiber optic collimator 7 is in the reference adjustment position before the adhesive is cured.

[0128] like Figure 13 The diagram shown is a complete flowchart of the method provided in this embodiment. It should be noted that after adjusting the fiber collimator 7 to the corresponding position, it is necessary to determine whether the optical path insertion loss is less than the insertion loss threshold. If it is less, the coupling is complete; if the optical path insertion loss is greater than or equal to the insertion loss threshold, the coupling adjustment needs to be performed again.

[0129] After the two fiber collimators 7 are coupled in the glass tube 8, the UV curing module 56 is moved to the corresponding position in the glass tube 8 to cure the adhesive. After curing, the optical path insertion loss is checked again to see if it is less than the insertion loss threshold. If it is less, the coupling is complete.

[0130] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
