[0060] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0061] The term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " generally indicates an "or" relationship between the related objects.

[0062] Example 1, as Figures 1-10 As shown, the present invention discloses an FA coupling device for a PLC optical chip, comprising: a PLC optical chip carrier mechanism 3 and a left six-axis FA clamping mechanism 1 2, a right six-axis FA clamping mechanism 4, a left six-axis FA clamping mechanism 2 8 arranged on the periphery of the PLC optical chip carrier mechanism 3, and an upper UV mechanism 7 and an upper visual mechanism 9 located above the PLC optical chip carrier mechanism 3; a side visual detection mechanism 6 is also provided on one side of the PLC optical chip carrier mechanism 3.

[0063] Specifically, the left six-axis FA clamping mechanism 1 2 or the left six-axis FA clamping mechanism 2 8 or the right six-axis FA clamping mechanism 4 includes a six-axis moving module 21 , and the six-axis moving module 21 is further provided with an end surface contact sensor 23 located on one side of the FA fixture 22 .

[0064] Furthermore, the six-axis moving module 21 is driven by an FA fixture 22 for positioning the FA fiber 24. Specifically, the FA fixture 22 includes an FA carrier 221 mounted on the six-axis moving module 21. The FA carrier 221 is provided with a retaining groove 222 for receiving the FA fiber 24. The FA carrier 221 is also provided with a fiber pressure block 223 for pressing the tail of the FA fiber 24, and an elastic pressure piece 224, which is fixed to the FA carrier 221 by a fixing screw 225 and presses the head of the FA fiber 24. An optical power meter 37 corresponding to the PLC optical chip 36 is also provided on one side of the mounting base 32.

[0065] Among them, the PLC optical chip carrier mechanism 3 includes a posture adjustment mechanism 31 arranged on the carrier 1, and the posture adjustment mechanism 31 is driven to have a mounting seat 32, and the mounting seat 32 is provided with an optical chip fixture 35 for positioning the PLC optical chip 36, and the mounting seat 32 is also provided with a reflector 2 34 and a reflector 1 33 corresponding to the side and bottom sides of the optical chip fixture 35.

[0066] Among them, the bottom UV component 5 includes a bracket 51 arranged on the periphery of the PLC optical chip carrier mechanism 3, and the bracket 51 is provided with a lateral displacement cylinder 1 521 which can be extended and retracted relative to the PLC optical chip carrier mechanism 3, and the lateral displacement cylinder 1 521 drives the oblique displacement cylinder 2 522, and the oblique displacement cylinder 2 522 drives the UV lamp fixing seat 53, and the UV lamp fixing seat 53 is provided with a UV lamp 1 54 corresponding to the PLC optical chip 36 supported on the PLC optical chip carrier mechanism 3.

[0067] Among them, the side visual detection mechanism 6 includes an X-axis displacement mechanism 61 arranged on the periphery of the PLC optical chip carrier mechanism 3, a slide is slidably arranged on the X-axis displacement mechanism 61, a position adjustment mechanism 62 is arranged on the slide, and the position adjustment mechanism 62 is driven to set a left-side visual component 64 corresponding to the PLC optical chip carrier mechanism 3.

[0068] Among them, the upper UV mechanism 7 includes a gantry arranged on the outside of the PLC optical chip carrier mechanism 3, and the gantry is provided with an X-axis displacement mechanism 71. The X-axis displacement mechanism 71 is driven to be provided with a Z-axis displacement mechanism 72 that can be lifted and lowered longitudinally. The Z-axis displacement mechanism 72 is driven to be provided with a driving mounting seat 73. The driving mounting seat 73 is provided with a Y-axis displacement mechanism 74 that can be laterally extended and retracted relative to the PLC optical chip carrier mechanism 3. The Y-axis displacement mechanism 74 is driven to be provided with a UV lamp 76 corresponding to the FA optical fiber 24 on the PLC optical chip carrier mechanism 3; and the Y-axis displacement mechanism 74 is also provided with a side reflector 75 and an upper visual mechanism 9 corresponding to the side reflector 75.

[0069] Example 2, as Figures 1-10 As shown, the present invention discloses a FA coupling device for a PLC optical chip, comprising: a PLC optical chip carrier mechanism 3 and a left six-axis FA clamping mechanism 1 2, a right six-axis FA clamping mechanism 4, a left six-axis FA clamping mechanism 2 8 arranged on the periphery of the PLC optical chip carrier mechanism 3, and an upper UV mechanism 7 and an upper visual mechanism 9 located above the PLC optical chip carrier mechanism 3; a side visual detection mechanism 6 is also provided on one side of the PLC optical chip carrier mechanism 3. Specifically, the structure of the product includes: two outputs on the left side and one input on the right side. Therefore, the positions of the left six-axis FA clamping mechanism 1 2, the left six-axis FA clamping mechanism 2 8, and the right six-axis FA clamping mechanism 4 in a limited space need to be set so that they do not affect each other after being displaced by a small distance.

[0070] Specifically, the left six-axis FA clamping mechanism 1 2 or the left six-axis FA clamping mechanism 2 8 or the right six-axis FA clamping mechanism 4 includes a six-axis moving module 21. Specifically, the six-axis moving module 21 includes an X-axis displacement mechanism 211 arranged on one side of the PLC optical chip carrier mechanism 3, and the X-axis displacement mechanism 211 is driven to have a Y-axis displacement mechanism 212, and the Y-axis displacement mechanism 212 is provided with a Z-axis tilting slide 213, and the Z-axis tilting slide 213 is driven to have a telescopic electric cylinder 214, and the telescopic electric cylinder 214 is driven to have an arc displacement slide 1 215, and the arc displacement slide 1 215 is driven to have an arc displacement slide 2 216, and the arc displacement slide 2 216 is driven to have a FA clamp 22. The X-axis displacement mechanism 211 and the Y-axis displacement mechanism 212 form a planar displacement mechanism. The displacement trajectory of the Z-axis tilting slide 213 forms a longitudinally inclined intersecting trajectory with the displacement plane of the planar displacement mechanism. The telescopic electric cylinder 214 drives the arc-shaped displacement slide 1 215 to perform a longitudinal tilting displacement. The displacement arc of the arc-shaped displacement slide 1 215 forms a longitudinal oscillating curved surface, while the displacement arc of the arc-shaped displacement slide 216 forms a transverse oscillating curved surface. Furthermore, the six-axis motion module 21 is equipped with an end contact sensor 23 located on one side of the FA fixture 22.

[0071] More specifically, the centers of the electric rotating radian tables of the single group of the left six-axis FA clamping mechanism 1 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8 are all at the front end of the product light output on the front end fixture. The advantage of placing them in the center is that when the electric radian axis swings the angle, the center of the product light output will not be displaced in the three linear directions of XYZ in space; when the angle swings, the front end center position remains unchanged, only the angle will change.

[0072] Furthermore, the six-axis moving module 21 is driven by an FA fixture 22 for positioning the FA fiber 24. Specifically, the FA fixture 22 includes an FA carrier 221 mounted on the six-axis moving module 21. The FA carrier 221 is provided with a retaining groove 222 for receiving the FA fiber 24. The FA carrier 221 is also provided with a fiber pressure block 223 for pressing the tail of the FA fiber 24, and an elastic pressure piece 224, which is fixed to the FA carrier 221 by a fixing screw 225 and presses the head of the FA fiber 24. Furthermore, an optical power meter 37 corresponding to the PLC optical chip 36 is also provided on one side of the mounting base 32. More specifically, vacuum adsorption holes are provided at the bottom and sides of the limiting groove 222. An elastic pressing piece 224 is attached to the top of the FA fixture 22. One end of the elastic pressing piece 224 is manually tightened and fixed to the FA carrier 221 via a fixing screw 225. A fiber pigtail limiting groove is provided at the rear end of the FA fixture 22. A swinging pressure block is provided above the fiber pigtail limiting groove. The limiting groove 222, the elastic pressing piece 224, and the combination of the fiber pigtail limiting groove and the swinging pressure block securely secure the FA optical fiber 24, preventing the FA optical fiber 24 from shifting during movement. More specifically, a guiding bevel is provided between the outer side of the swinging pressure block and the fiber pigtail limiting groove to facilitate the insertion of the optical fiber pigtail between the swinging pressure block and the fiber pigtail limiting groove.

[0073] The PLC optical chip carrier mechanism 3 includes a posture adjustment mechanism 31 mounted on the carrier 1. A mounting base 32 is driven by the posture adjustment mechanism 31. The posture adjustment mechanism 31 includes a Y-axis motorized shaft 311 mounted on the carrier 1. A swing mechanism 1 312 is driven by the Y-axis motorized shaft 311. The swing mechanism 1 312 drives a swing mechanism 2 313. The swing mechanism 2 313 is mounted on a rotation mechanism 314. The rotation mechanism 314 drives the mounting base 32. An optical chip fixture 35 for positioning a PLC optical chip 36 is mounted on the mounting base 32. Also mounted on the mounting base 32 are a second reflector 34 and a first reflector 33, corresponding to the sides and bottom of the optical chip fixture 35. Specifically, the second reflector 34 and the first reflector 33 are located on the sides and bottom of the optical chip fixture 35 and are larger than the PLC optical chip 36. During the coupling process, the closer the optical chip fixture 35 is to the optical chip fixture 35, the better, provided that other moving parts do not interfere. The side reflector 75 is a right-angle prism mounted on the side of the front end of the lens of the upper vision mechanism 9. It deflects the visual light path by 90 degrees. Because the PLC optical chip 36 is made of transparent material, a reflector is required on the back of the product to reflect light and increase the contrast of the captured image. When monitoring the angle between the side FA and the chip, the side vision is used; when monitoring the distance between the FA and the Guangxin, the upper vision mechanism 9 is directly used to achieve top-down visual inspection.

[0074] Among them, the bottom UV component 5 includes a bracket 51 arranged on the periphery of the PLC optical chip carrier mechanism 3, and the bracket 51 is provided with a lateral displacement cylinder 1 521 which can be extended and retracted relative to the PLC optical chip carrier mechanism 3, and the lateral displacement cylinder 1 521 drives the oblique displacement cylinder 2 522, and the oblique displacement cylinder 2 522 drives the UV lamp fixing seat 53, and the UV lamp fixing seat 53 is provided with a UV lamp 1 54 corresponding to the PLC optical chip 36 supported on the PLC optical chip carrier mechanism 3.

[0075] Among them, the side visual detection mechanism 6 includes an X-axis displacement mechanism 61 arranged on the periphery of the PLC optical chip carrier mechanism 3, a slide is slidably arranged on the X-axis displacement mechanism 61, a position adjustment mechanism 62 is arranged on the slide, and the position adjustment mechanism 62 is driven to set a left-side visual component 64 corresponding to the PLC optical chip carrier mechanism 3.

[0076] The upper UV mechanism 7 includes a gantry mounted outside the PLC optical chip carrier mechanism 3. The gantry is equipped with an X-axis displacement mechanism 71. The X-axis displacement mechanism 71 drives a Z-axis displacement mechanism 72 capable of longitudinal elevation. The Z-axis displacement mechanism 72 drives a drive mounting seat 73. The drive mounting seat 73 is equipped with a Y-axis displacement mechanism 74 capable of transverse extension and contraction relative to the PLC optical chip carrier mechanism 3. The Y-axis displacement mechanism 74 drives a UV lamp 76 corresponding to the FA optical fiber 24 on the PLC optical chip carrier mechanism 3. The Y-axis displacement mechanism 74 also has a side reflector 75 and an upper vision mechanism 9 corresponding to the side reflector 75. More specifically, the side reflector 75 and the upper vision mechanism 9 are fixed to the Y-axis displacement mechanism 74. The smaller the gap between the side reflector 75 and the upper visual mechanism 9, the better; the smaller it is, the smaller the displacement of the Y-axis displacement mechanism 2 74 will be, and the closer the working distance of the two sets of lenses in the upper and lower directions, the better, so that the Z-axis displacement distance will be smaller.

[0077] Example 3, based on Example 2, Figures 1-10 As shown, the mounting base 32 of the UV lamp 54 is coaxially inserted into the UV lamp fixing base 53. By adjusting the rotation angle of the mounting base 32 of the UV lamp 54 inserted into the UV lamp fixing base 53, the longitudinal irradiation trajectory of the UV lamp 54 can be adjusted. Furthermore, in other embodiments, the side vision detection mechanism 6 includes an X-axis displacement mechanism 61 disposed on the periphery of the PLC optical chip carrier mechanism 3. A slide is slidably mounted on the X-axis displacement mechanism 61, and a position adjustment mechanism 62 is mounted on the slide. The position adjustment mechanism 62 drives a left-side vision component 64 corresponding to the PLC optical chip carrier mechanism 3. The slide is also provided with a manual adjustment mechanism 63. The manual adjustment mechanism 63 adopts a screw adjustment method in the prior art. The relative horizontal displacement position of the slide is adjusted by rotating the screw to achieve manual adjustment.

[0078] Example 4, as Figures 1-10 As shown, a coupling method of an FA coupling device of a PLC optical chip is implemented using the FA coupling device of a PLC optical chip in Example 2, and includes the following steps:

[0079] Step S1, performing a loading and positioning operation on the FA optical fiber 24 and the PLC optical chip 36, the loading and positioning operation includes:

[0080] Several FA optical fibers 24 are positioned on the FA fixtures 22 of the left six-axis FA clamping mechanism 1 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8. In this embodiment, the left six-axis FA clamping mechanism 1 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8 are respectively positioned by an X-axis displacement mechanism 211 disposed on one side of the PLC optical chip carrier mechanism 3, and a Y-axis displacement mechanism 212 driven by the X-axis displacement mechanism 211, forming a planar displacement mechanism for lateral and longitudinal displacement. The Z-axis tilting slide 213, driven and connected to the Y-axis displacement mechanism 212, then achieves oblique displacement. In this embodiment, the relative displacement between the tilting sliders of the Z-axis tilting slide 213 can adjust the longitudinal lifting and lateral displacement in combination. The displacement trajectory of the Z-axis tilting slide 213 forms a longitudinally inclined displacement intersection trajectory with the displacement plane of the planar displacement mechanism, thereby achieving position adjustment in the oblique direction and improving the position adjustment flexibility and stability of the displacement structure. The telescopic electric cylinder 214 then drives the arc-shaped displacement slide 1 215 to move along the drive trajectory of the telescopic electric cylinder 214. Arc-shaped displacement slide 1 215 drives arc-shaped displacement slide 2 216, which in turn drives the FA fixture 22. The displacement arc of arc-shaped displacement slide 1 215 forms a longitudinal swinging curved surface, while the displacement arc of arc-shaped displacement slide 216 forms a transverse swinging curved surface. This achieves six-axis movement that accommodates the multi-angle FA fixture 22 of the present invention. Furthermore, the six-axis movement module 21 is equipped with an end contact sensor 23 located on one side of the FA fixture 22, which assists in position adjustment and monitoring. This further enhances the flexibility and stability of position adjustment.

[0081] The PLC optical chip 36 is placed and positioned on the optical chip fixture 35 of the PLC optical chip carrier mechanism 3. In this embodiment, the optical chip fixture 35 adjusts the posture of the PLC optical chip 36 held by the optical chip fixture 35 via the posture adjustment mechanism 31 within the PLC optical chip carrier mechanism 3. The Y motorized axis 311 within the posture adjustment mechanism 31 drives the mounting base 32 relative to the left six-axis FA clamping mechanism 1 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8 via the swing mechanism 1 312, swing mechanism 2 313, and rotation mechanism 314. Furthermore, the swing mechanism 1 312 and swing mechanism 313 can adjust the curved surface rotation in two intersecting directions, thereby adjusting the angular posture of the PLC optical chip 36 on the carrier 1. The first swing mechanism 312 and its swinging motion, in conjunction with the rotation mechanism 314, enable multi-directional and multi-angle posture adjustment, facilitating relative position adjustment between the FA fiber 24 and the PLC optical chip 36 and ensuring flexibility for coupling adjustment. Furthermore, the posture adjustment mechanism 31 is driven by a mounting seat 32, which is equipped with an optical chip fixture 35 for positioning the PLC optical chip 36. Furthermore, the mounting seat 32 is equipped with a second reflector 34 and a first reflector 33, corresponding to the side and bottom sides of the optical chip fixture 35.

[0082] Step S2: Position adjustment and drive coupling are performed on the FA optical fiber 24 and the PLC optical chip 36. Position adjustment and drive coupling include:

[0083] A red light source emits, capturing images of the FA fiber 24 and PLC optical chip 36 via the upper visual mechanism 9, the side visual detection mechanism 6, and the end-face contact sensor 23 at the front end of the FA. This then drives the right-side six-axis FA clamping mechanism 4, aligning the clamped FA fiber 24 with the PLC optical chip 36. The red light passes through the PLC optical chip 36 and is then emitted, with the left-side visual component 64 locating the light spot. Specifically, the light source is a desktop instrument, and light is introduced from the right side of the fiber by manually plugging and unplugging the fiber optic interface. The left-side visual component 64 is the left-side spot camera.

[0084] The wavelength band of the light source is switched, and after passing through the FA optical fiber 24 positioned on the right six-axis FA clamping mechanism 4, it is moved to the front of the optical power meter 37 to obtain the optical power value.

[0085] The FA optical fiber 24 positioned on the right six-axis FA clamping mechanism 4 returns to the position when coupling the red light.

[0086] The FA optical fiber 24 clamped by the left six-axis FA clamping mechanism 1 2 and the left six-axis FA clamping mechanism 2 8 is driven to the light output position of the clamped FA optical fiber 24 through the upper visual mechanism 9 and the side visual detection mechanism 6, as well as the end face contact sensor 23 at the front end of the FA. The extinction ratio test instrument is used to obtain the extinction ratio and optical power values, which are compared with the optical power values ​​obtained when the light is input to determine whether the positions of the two groups of FA at this time meet the required values. If not, the six-axis moving module 21 is driven to adjust until the extinction ratio value and the parameters of the optical power meter 37 reach the required values. More specifically, the extinction ratio test instrument adopts the extinction ratio test instrument in the existing technology. The specific model selection is not listed and elaborated here one by one. As long as the extinction ratio test can be basically achieved, it is sufficient.

[0087] Step S3, performing glue curing on the FA optical fiber 24 and the PLC optical chip 36, the glue curing comprising:

[0088] Apply glue on the upper and bottom of the PLC optical chip 36, drive the upper UV mechanism 7 and the bottom UV component 5 to move to the PLC optical chip 36, turn on the UV lamp to cure the glue, and complete the curing operation.

[0089] Example 5: Based on Example 4, in this example, the FA coupling device of a PLC optical chip in Example 2 is adopted, and the FA coupling device of the PLC optical chip 36 is connected to the host computer control through a control mechanism.

[0090] A coupling method for an FA coupling device of a PLC optical chip comprises the following steps:

[0091] The host computer controls the control mechanism to drive the left six-axis FA clamping mechanism 1 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8 to clamp and position the FA fiber 24. It also controls the PLC optical chip carrier mechanism 3 to position the PLC optical chip 36. Positioning information is then fed back to the host computer via the control mechanism. The upper vision mechanism 9, the side vision detection mechanism 6, and the end-face contact sensor 23 at the front end of the FA acquire position images and sensor parameters (pressure parameters or distance parameters) of the FA fiber 24 and PLC optical chip 36. These are then fed back to the host computer via the control mechanism.

[0092] The upper computer obtains the displacement trajectory driving instruction through the displacement trajectory algorithm based on the positioning information, position image and sensor parameters, and sends it to the control mechanism to drive the left six-axis FA clamping mechanism 1 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8 to adjust the relative position of the FA optical fiber 24 and the PLC optical chip 36, and perform position adjustment and drive coupling on the FA optical fiber 24 and the PLC optical chip 36.

[0093] Specifically, the position adjustment and drive coupling include: emitting red light through the light source, obtaining the position image of the FA optical fiber 24 and the PLC optical chip 36 through the upper visual mechanism 9 and the side visual detection mechanism 6, as well as the end face contact sensor 23 at the front end of the FA, driving the right six-axis FA clamping mechanism 4 to drive the clamped FA optical fiber 24 to align with the PLC optical chip 36, and the red light is emitted after passing through the PLC optical chip 36, and the position of the light point is located by the left spot camera.

[0094] After switching the wavelength of the light source, the FA optical fiber 24 positioned on the right six-axis FA clamping mechanism 4 is moved to the front of the optical power meter 37 to obtain the optical power value. The FA optical fiber 24 positioned on the right six-axis FA clamping mechanism 4 returns to the position when the red light was coupled; the FA optical fiber 24 clamped by the left six-axis FA clamping mechanism 1 2 and the left six-axis FA clamping mechanism 2 8 respectively passes through the upper visual mechanism 9 and the side visual detection mechanism 6, as well as the end face contact sensor 23 at the front end of the FA, and drives the clamped FA optical fiber 24 to the light output position. The extinction ratio and optical power values ​​are obtained by the extinction ratio test instrument and compared with the optical power value obtained when the light was input to determine whether the positions of the two FA groups at this time meet the required values. If not, the six-axis moving module 21 is driven to adjust until the extinction ratio value and the parameters of the optical power meter 37 reach the required values.

[0095] The FA optical fiber 24 and the PLC optical chip 36 are glued and cured. The glue curing includes: applying glue on the upper and bottom of the PLC optical chip 36, driving the upper UV mechanism 7 and the bottom UV component 5 to move to the PLC optical chip 36, turning on the UV lamp to cure the glue, and completing the curing operation.

[0096] Working principle:

[0097] The present invention provides an FA coupling device and a coupling method for a PLC optical chip that are easy to operate and have high coupling stability. The device improves the flexibility of the spatial alignment of the FA optical fiber 24 and the PLC optical chip 36, flexibly positions the light output position of the PCL optical chip, and the clamping method of the FA optical fiber 24 facilitates coupling and angle adjustment of glue dispensing, which is beneficial to glue dispensing at the top and bottom.

[0098] The present invention only requires placing the left and right FA optical fibers 24 and PLC on a fixed fixture, and applying glue on the top and bottom after coupling is completed; the FA optical fiber 24 and the PLC optical chip 36 are aligned, coupled, and UV cured using equipment, which simplifies the operating steps for the operator and improves efficiency.

[0099] The fixtures on both sides of the FA connector feature contact force control. Using top and side visual imaging, they precisely position the FA fibers 24 on both sides and control the distance between the FA fibers 24 and the end face of the PLC optical chip 36. This design makes the fixture easy for the operator to operate. The PLC fixture's adaptive structure accommodates a wide range of PLC optical chip 36 sizes, enhancing the device's compatibility. The device is equipped with a high-precision motorized slide with a 50nm resolution. Using visual guidance, it precisely positions the FA fibers 24 and PLC optical chip 36. Four high-power LED UV curing lamps, mounted on top and bottom, facilitate the curing of the glue between the FA fibers 24 and PLC optical chip 36, preventing the glue from being partially cured and affecting the final coupling position during UV curing. A micro PD probe integrated on the side of the fixture measures the output power of the FA fibers 24 before coupling. This power serves as a reference value, with which the output power after coupling is compared to determine compliance. In order to accurately find the position where the PLC optical chip 36 emits light, a visible red light source in the existing technology is set on the equipment for collimation and aiming. The visible red light is first incident on the PLC chip through the side camera to locate the light output point, and then the FA is guided to move to the light output position to accurately align the light port position.

The technical scope of the present invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
