In addition, the character " / " generally represents an "or" relationship between the associated objects before and after.

[0025] In the first embodiment, as Figures 1 - 10 shown, the present invention discloses an FA coupling device for a PLC optical chip, including: a PLC optical chip carrier mechanism 3 and a left six-axis FA clamping mechanism 1, a right six-axis FA clamping mechanism 4, and a left six-axis FA clamping mechanism 2 disposed outside the PLC optical chip carrier mechanism 3, and an upper UV mechanism 7 and an upper vision mechanism 9 located above the PLC optical chip carrier mechanism 3; a side vision detection mechanism 6 is further disposed on one side of the PLC optical chip carrier mechanism 3.

A sliding seat is slidably provided on the first X-axis displacement mechanism 61. A position adjustment mechanism 62 is provided on the sliding seat. A left vision component 64 corresponding to the PLC optical chip carrier mechanism 3 is driven and provided on the position adjustment mechanism 62.

[0032] Embodiment 2, as Figures 1 - 10 shown, the present invention discloses a FA coupling device for a PLC optical chip, including: a PLC optical chip carrier mechanism 3 and a left six-axis FA clamping mechanism I 2, a right six-axis FA clamping mechanism 4, a left six-axis FA clamping mechanism II 8 arranged outside the PLC optical chip carrier mechanism 3, and an upper UV mechanism 7 and an upper vision mechanism 9 located above the PLC optical chip carrier mechanism 3; a side vision detection mechanism 6 is also arranged on one side of the PLC optical chip carrier mechanism 3. Specifically, the structure of the product includes: there are two outputs on the left side and one input on the right side. Therefore, the positions of the left six-axis FA clamping mechanism I 2, the left six-axis FA clamping mechanism II 8, and the right six-axis FA clamping mechanism 4 in the limited space need to not affect each other after a small distance displacement.

[0033] Specifically, the left six-axis FA clamping mechanism I 2 or the left six-axis FA clamping mechanism II 8 or the right six-axis FA clamping mechanism 4 includes a six-axis movement module 21. Specifically, the six-axis movement module 21 includes an X-axis displacement mechanism 211 arranged on one side of the PLC optical chip carrier mechanism 3, a Y-axis displacement mechanism 212 is drivingly arranged on the X-axis displacement mechanism 211, a Z-axis tilting slide 213 is arranged on the Y-axis displacement mechanism 212, a telescopic electric cylinder 214 is drivingly arranged on the Z-axis tilting slide 213, an arc displacement slide I 215 is drivingly arranged on the telescopic electric cylinder 214, an arc displacement slide II 216 is drivingly arranged on the arc displacement slide I 215, and a FA fixture 22 is drivingly arranged on the arc displacement slide II 216. The X-axis displacement mechanism 211 and the Y-axis displacement mechanism 212 form a planar displacement mechanism, and the displacement track of the Z-axis tilting slide 213 forms a longitudinally inclined displacement intersection track with the displacement plane of the planar displacement mechanism; the telescopic electric cylinder 214 drives the arc displacement slide I 215 to longitudinally incline and displace; the displacement arc surface of the arc displacement slide I 215 forms a longitudinally swinging curved surface, and the displacement arc surface of the arc displacement slide II 216 forms a transversely swinging curved surface. Moreover, an end face contact inductor 23 is also arranged on the six-axis movement module 21 on one side of the FA fixture 22.

[0034] More specifically, the centers of the electric rotation radian tables of the single-group left six-axis FA clamping mechanism I 2, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism II 8 are all at the front end of the product where light exits on the front fixture. The advantage of placing them in the center is that when the electric radian axis swings, the center of the light exiting from the product will not have displacement in the three linear directions of space XYZ; when the angle swings, only the angle changes while the front center position remains unchanged.

[0035] Further, an FA fixture 22 for positioning the FA optical fiber 24 is drivingly provided on the six-axis moving module 21. Specifically, the FA fixture 22 includes an FA stage 221 provided on the six-axis moving module 21. A limiting groove 222 for receiving the FA optical fiber 24 is provided on the FA stage 221. A fiber optic pressing block 223 for pressing against the tail of the FA optical fiber 24 is further provided on the FA stage 221, and an elastic pressing piece 224 defined on the FA stage 221 by a fixing screw 225, and the elastic pressing piece 224 presses against the head of the FA optical fiber 24. Moreover, a optical power meter 37 corresponding to the PLC optical chip 36 is provided on one side of the mounting seat 32. More specifically, vacuum suction holes are provided at the bottom and side of the limiting groove 222. The FA fixture 22 is attached with an elastic pressing piece 224.

A fiber optic pigtail limiting groove is provided at the rear end of the FA fixture 22. A swinging pressing block is provided at the upper part of the fiber optic pigtail limiting groove. The FA optical fiber 24 is stably fixed by the combination of the limiting groove 222 and the elastic pressing piece 224, as well as the fiber optic pigtail limiting groove and the swinging pressing block, to prevent the position of the FA optical fiber 24 from moving during the movement. More specifically, an inclined guide surface is provided between the outer side of the swinging pressing block and the fiber optic pigtail limiting groove, facilitating the fiber optic pigtail to be clamped between the swinging pressing block and the fiber optic pigtail limiting groove.

More specifically, the second mirror 34 and the first mirror 33 are located at the side and below of the optical chip fixture 35, and their sizes are larger than the PLC optical chip 36; during the coupling process, when other moving parts do not interfere, the closer the distance is to the optical chip fixture 35, the better. The side mirror 75 is a right-angled prism installed on the front side of the lens of the upper vision mechanism 9, and the side mirror 75 deflects the vision optical path by 90 degrees. Since the PLC optical chip 36 is made of a transparent material, a mirror needs to be added to the back of the product to reflect light and increase the contrast of the collected image. When it is necessary to monitor the angle between the side FA and the chip, the side vision is used; when it is necessary to monitor the distance between the FA and the Guangxin, the upper vision mechanism 9 is directly used to achieve the top-down vision detection.

A second UV lamp 76 corresponding to the FA optical fiber 24 on the PLC optical chip carrier mechanism 3 is driven and arranged on the second Y-axis displacement mechanism 74; and a side mirror 75 and an upper vision mechanism 9 corresponding to the side mirror 75 are further arranged on the second Y-axis displacement mechanism 74. More specifically, the side mirror 75 and the upper vision mechanism 9 are fixed on the second Y-axis displacement mechanism 74. The left-right adjacent gap between the side mirror 75 and the upper vision mechanism 9 is preferably as small as possible; the smaller it is, the smaller the displacement of the second Y-axis displacement mechanism 74 during movement. The working distances of the two groups of lenses in the up-down direction are preferably as close as possible, so that the Z-axis displacement distance is smaller.

[0040] Embodiment 3, on the basis of Embodiment 2, as Figures 1 - 10 shown, the mounting seat 32 of the first UV lamp 54 is coaxially inserted into the UV lamp fixing seat 53.

By rotating the screw, the relative horizontal displacement position of the sliding seat is adjusted to achieve manual adjustment.

In this embodiment, the left six-axis FA clamping mechanism 1, the right six-axis FA clamping mechanism 4, and the left six-axis FA clamping mechanism 2 8 are composed of an X-axis displacement mechanism 211 provided on one side of the PLC optical chip carrier mechanism 3, and a Y-axis displacement mechanism 212 driven on the X-axis displacement mechanism 211 to form displacements in the horizontal and vertical directions in the planar displacement mechanism. Then, the Z-axis tilting slide 213 driven and connected on the Y-axis displacement mechanism 212 is used to achieve displacement in the oblique axis direction. In this embodiment, the relative displacement between the tilting sliders of the Z-axis tilting slide 213 can adjust the combination of the longitudinal lifting and the horizontal displacement. The displacement trajectory of the Z-axis tilting slide 213 forms a longitudinally inclined displacement cross trajectory with the displacement plane of the planar displacement mechanism; thereby realizing the position adjustment in the inclined direction and improving the flexibility and stability of the position adjustment of the displacement structure.

[0049] The upper computer obtains the displacement trajectory driving instruction through the displacement trajectory algorithm according to the positioning information, the position image, and the 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 positions of the FA optical fiber 24 and the PLC optical chip 36, and perform position adjustment and driving coupling on the FA optical fiber 24 and the PLC optical chip 36.

Driving the six-axis FA clamping mechanism 4 on the right side to drive the clamped FA optical fiber 24 to align with the PLC optical chip 36. After the red light passes through the PLC optical chip 36, it emits, and the position of the light spot is located by the left spot camera.

[0051] Switch the wavelength band of the light source. After passing through the FA optical fiber 24 positioned on the six-axis FA clamping mechanism 4 on the right side, move to the front of the optical power meter 37 to obtain the optical power value. The FA optical fiber 24 positioned on the six-axis FA clamping mechanism 4 on the right side returns to the position when coupling the red light. The FA optical fibers 24 clamped by the six-axis FA clamping mechanism one 2 and the six-axis FA clamping mechanism two 8 on the left side respectively pass through 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, driving the emitting positions of the clamped FA optical fibers 24. Through the extinction ratio test instrument, obtain the extinction ratio and the optical power value, and compare with the optical power value obtained when the light enters. Judge whether the positions of the two groups of FAs at this time meet the required values. If not, drive the six-axis movement module 21 to adjust until the extinction ratio value and the parameters of the optical power meter 37 reach the required values.

The clamping method of the FA optical fiber 24 facilitates the realization of coupling and the angle adjustment of glue application, which is beneficial for upper and bottom glue application.

[0054] The present invention only needs to place the left and right side FA optical fibers 24 and the PLC on the fixed fixtures, apply glue to the upper and bottom after coupling is completed; the alignment of the FA optical fiber 24 and the PLC optical chip 36, light coupling, and UV curing are completed by the equipment, which simplifies the operation steps for the operator and improves the efficiency at the same time.

[0055] The fixtures on both sides of the FA are equipped with contact force control function. At the same time, through the visual imaging from above and the side, the FA optical fibers 24 on both sides can be accurately placed, and the distance between the FA optical fiber 24 and the end face of the PLC optical chip 36 can be controlled. The designed fixtures are easy for operators to operate. The design of the PLC fixture adopts an adaptive structure, which can be compatible with multiple sizes of PLC optical chips 36, improving the compatibility of the equipment. The equipment is equipped with a high-precision electric slide table with a resolution of 50 nm. Through the cooperation of vision, the spatial positions of the FA optical fiber 24 and the PLC optical chip 36 can be accurately positioned. The equipment is equipped with a total of 4 high-power LED UV curing lamp heads up and down, which provides convenience for the curing of the glue between the FA optical fiber 24 and the PLC optical chip 36, and there will be no situation where the glue is not cured, and when UV curing, it affects the coupling completion position of the FA and the PLC optical chip 36. A micro PD probe is integrated on the side of the jig, which is used to measure the light output power of the FA optical fiber 24 before coupling. This power is used as a reference value, and the light output power after coupling is compared with it to determine whether it meets the requirements. In order to accurately find the light output position point of the PLC optical chip 36, a visible red light source in the prior art is set on the equipment for collimation and aiming. The visible red light is first incident on the PLC chip and the light spot is located through the side camera, and then the FA is guided to the light output position to accurately align the optical port positions.
