[0001] The invention relates to the fields of mechanical engineering and optical fiber communication technology, and in particular to a fast pick-and-place fixture, method and coupling device for an FA optical fiber module. Background Art

[0002] FA fiber modules are very important optical devices in the field of optical communication technology. Their fast and accurate placement can effectively improve the precise and rapid coupling of FA optical fibers and chips in optoelectronic conversion modules, which is of great significance to the development of optical communication technology. However, most traditional FA fiber modules are placed by adsorption or clamping. The adsorption method easily causes position errors in the FA fiber modules, while the clamping method easily causes certain deformations in the FA fiber modules, which affects the performance and cannot meet the requirements of modern optical fiber communication systems for high efficiency and stability. Therefore, how to achieve accurate and fast placement of FA fiber modules is a problem that needs to be solved urgently. Summary of the invention

[0003] The technical problem solved by the present application is: to overcome the deficiencies of the prior art and provide a fast pick-up and placement fixture, method and coupling device for FA optical fiber modules, which can simultaneously use adsorption and clamping positioning methods to complete the fast and accurate pick-up and placement of FA optical fiber modules.

[0004] The technical solutions provided by this application are as follows:

[0005] A quick pick-and-place clamp for FA optical fiber modules, comprising a clamp body, a right clamp, a left clamp and a butterfly-shaped bidirectional screw, the clamp body being provided with a pick-and-place portion, the top ends of the right clamp and the left clamp being fixedly mounted on opposite sides of the pick-and-place portion respectively, the butterfly-shaped bidirectional screw being rotatably connected to the pick-and-place portion, the butterfly-shaped bidirectional screw being threadedly connected to both the right clamp and the left clamp, and the thread directions of the threaded connections being opposite; the width of the bottom end of the pick-and-place portion being the same as that of the FA optical fiber module; a connected air path being provided inside the clamp body, one end of the air path being connected to the bottom end of the pick-and-place portion, and the other end being connected to the side of the pick-and-place portion where the right clamp or the left clamp is not mounted, the end of the air path at the bottom end of the pick-and-place portion being used to absorb or release the FA optical fiber module, and the end of the air path at the side of the pick-and-place portion being used to connect to an air source.

[0006] The right clamp is fixed to one side of the clamp body by a right fixing screw, and the left clamp is fixed to the other side of the clamp body by a left fixing screw.

[0007] The right clamp and the left clamp are both provided with a square notch on one side facing the pick-and-place portion. Along the height direction of the pick-and-place portion, the square notch is located between the right fixing screw and the butterfly-shaped bidirectional screw.

[0008] The butterfly-shaped bidirectional screw is a split structure, including a screw and a butterfly head. The screw is rotatably connected to the pick-up and release part. Both ends of the screw are provided with reverse external threads. The two ends of the screw pass through the right clamp and the left clamp respectively and are threadedly connected with the right clamp and the left clamp. The butterfly head is connected to the end of the screw extending out of the right clamp or the left clamp.

[0009] The installation method of the butterfly-shaped bidirectional screw includes: installing the screw with the pick-and-place part, then rotating the screw, installing the right clip and the left clip at the two ends of the screw respectively, after the right clip and the left clip are installed to fit with the pick-and-place part, fixing the top end of the right clip to one side of the pick-and-place part by the right fixing screw, fixing the top end of the left clip to the other side of the pick-and-place part by the left fixing screw, and finally connecting the butterfly head with internal threads to one end of the screw and fixing it with thread glue.

[0010] The direction from the right clamp to the left clamp is the width direction of the pick-and-place portion. Along the vertical downward direction, the pick-and-place portion has a large width area, an area with gradually decreasing width, and a small width area. The width of the large width area is greater than that of the small width area, and the width of the small width area is the same as that of the FA optical fiber module.

[0011] The clamp body is also provided with a connecting portion, which is located on the top of the pick-and-place portion, so that the connecting portion and the pick-and-place portion form a T shape, and the connecting portion is used to connect a driving device that drives the clamp body to move.

[0014] Move the fixture body to the top of the FA optical fiber module, and use the air path to generate suction at the bottom of the pick-and-place part to adsorb the FA optical fiber module;

[0015] By rotating the butterfly-shaped bidirectional screw, the distance between the left clamp and the right clamp is reduced until the left clamp and the right clamp fit with the side of the pick-and-place part, thereby correcting the posture of the FA optical fiber module and completing the adsorption of the FA optical fiber module by the fixture body.

[0016] After the fixture body completes the adsorption of the FA fiber optic module, the fixture body is moved above the tube shell to be coupled, and the fixture body drives the FA fiber optic module to position in the direction from the right clamp to the left clamp, and then moves in a direction parallel to the symmetry plane between the right clamp and the left clamp, and fine-tunes the position of the FA fiber optic module until it is aligned. The suction force at the bottom of the pick-and-place part disappears through the air path, and the FA fiber optic module is coupled to the tube shell.

The optical module positioning and power supply component is used to position the tube shell. The optical fiber adjustment component comprises a five-degree-of-freedom adjustment platform, a longitudinal support frame, a transverse support frame and any of the above-mentioned quick-pick-and-place clamps. The longitudinal support frame is connected to the five-degree-of-freedom adjustment platform, and the five-degree-of-freedom adjustment platform is used to drive the longitudinal support frame to perform five-degree-of-freedom movement. The transverse support frame is fixedly installed on the longitudinal support frame, and the mounting portion of the quick-pick-and-place clamp is fixedly installed on the lower surface of the transverse support frame; the visual monitoring component is used to monitor the relative position of the FA optical fiber module and the tube shell to ensure that the FA optical fiber module is aligned with the chip in the tube shell.

[0037] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] The present application embodiment discloses a quick pick-and-place fixture for a FA optical fiber module, such as Figure 1 As shown, it includes a clamp body 1, a right clamping piece 12, a left clamping piece 13, a butterfly-shaped bidirectional screw 14, a right fixing screw 15, a left fixing screw 16, and a pagoda air nozzle 17.

[0039] The fixture body 1 is a basic component of the FA fiber optic module quick pick-and-place fixture, and is used to connect and fix other components. The fixture body 1 is provided with a pick-and-place portion, and the top ends of the right clamp 12 and the left clamp 13 are respectively installed on the opposite sides of the pick-and-place portion, and the bottom ends of the right clamp 12 and the left clamp 13 are located below the bottom end of the pick-and-place portion. There is a connected air path inside the fixture body 1, one end of the air path is located at the bottom end of the pick-and-place portion, and the other end is located at the side of the pick-and-place portion where the right clamp 12 or the left clamp 13 is not installed. The pagoda air nozzle 17 is installed on the side of the fixture body 1 and is connected to the end of the air path, and is connected to the air path inside the fixture body 1. The end of the air path at the bottom of the pick-and-place portion is used to absorb or release the FA fiber optic module, and the end of the air path on the side of the pick-and-place portion is used to connect to the air source, so that the bottom of the pick-and-place portion generates suction or does not generate suction, thereby realizing the adsorption and release of the FA fiber optic module.

[0040] The right clamp 12 and the left clamp 13 are fixed on both sides of the pick-and-place part, the right clamp 12 has a light hole and a right-handed threaded hole, and the left clamp 13 has a light hole and a left-handed threaded hole; the right clamp 12 is fixed to the right side of the clamp body 1 by a right fixing screw 15, and the left clamp 13 is fixed to the left side of the clamp body 1 by a left fixing screw 16; the butterfly-shaped bidirectional screw 14 is a split structure, including a screw and a butterfly head, the screw is rotatably connected to the pick-and-place part, and opposite external threads are arranged at both ends of the screw, the two ends of the screw pass through the right clamp 12 and the left clamp 13 respectively and are threadedly connected with the right clamp 12 and the left clamp 13, the butterfly head is connected to the end of the screw extending out of the right clamp 12 or the left clamp 13, so that the opening and closing of the left clamp 13 and the right clamp 12 can be adjusted by rotating the butterfly-shaped bidirectional screw 14. When the butterfly-shaped bidirectional screw 14 rotates counterclockwise, the two clamps are deformed to a certain extent and the distance between them increases. When the butterfly-shaped bidirectional screw 14 rotates clockwise, the two clamps are clamped to achieve the positioning of the FA fiber optic module. Since the width of the end of the clamp body 1 is the same as that of the FA fiber optic module, the left and right clamps will not squeeze the FA, and the FA fiber optic module can be effectively protected, thereby ensuring the performance of the FA fiber optic module.

[0041] During the coupling process of the FA optical fiber module, the FA optical fiber module is firstly adsorbed by adsorption, and then the distance between the left clamping piece 13 and the right clamping piece 12 is adjusted by the butterfly-shaped bidirectional screw 14 to achieve the correction of the posture of the FA optical fiber module.

[0042] When installing the right clamp 12 and the left clamp 13 on both sides of the pick-and-place part, first install the screw rod with the pick-and-place part, and then rotate the screw rod to install the right clamp 12 and the left clamp 13 at both ends of the screw rod respectively. After the right clamp 12 and the left clamp 13 are installed to fit with the pick-and-place part, fix the top end of the right clamp 12 to one side of the pick-and-place part by the right fixing screw 15, and fix the top end of the left clamp 13 to the other side of the pick-and-place part by the left fixing screw 16. Finally, connect the butterfly head with internal threads to one end of the screw rod and fix it with thread glue.

[0043] The right clamp 12 and the left clamp 13 are provided with square notches on one side facing the pick-up and release portion, and are arranged symmetrically on the left and right sides. The square notches are located between the right fixing screw 15 and the butterfly-shaped bidirectional screw 14, so that the right clamp 12 and the left clamp 13 have better flexibility to facilitate opening and clamping.

[0044] The direction between the two sides of the right clamp 12 and the left clamp 13 of the pick-and-place part is the width direction of the pick-and-place part. Along the vertical downward direction, the pick-and-place part has a large width area, a gradually decreasing width area and a small width area. The width of the large width area is greater than the small width area, and the width of the small width area is the same as that of the FA optical fiber module. The large width area can ensure the rigidity and strength of the fixture as a whole, and the small width area can adapt to the narrow space in the optical module shell.

[0045] like Figure 2 As shown, the fixture body 1 is also provided with a connection part, which is located at the top of the pick-and-place part, so that the overall shape of the fixture body 1 is T-shaped, and the connection part is used to connect the driving device that drives the fixture body 1 to move. In the process of the fixture body 1 clamping the FA fiber optic module, since it is first sucked and then positioned by the right clamp 12 and the left clamp 13, the position of the FA fiber optic module in the direction from the right clamp 12 to the left clamp 13 is accurate. Therefore, after the fixture body 1 clamps the FA fiber optic module, the driving device drives the clamped FA fiber optic module to be positioned in the direction from the right clamp 12 to the left clamp 13, and then moves in a direction parallel to the symmetry plane between the right clamp 12 and the left clamp 13 to fine-tune the position of the FA fiber optic module.

[0046] like Figure 3 As shown, the interior of the clamp body 1 has a connected air path, one end of the air path is connected to the pagoda air nozzle 17, and the other end is arranged at the end of the clamp body 1, and a square outlet is also provided at the end of the clamp body 1. The length of the square outlet is not less than the diameter of the air path, which increases the adsorption force on the FA optical fiber module and is used to realize the adsorption and release of the FA optical fiber module.

[0047] The FA optical fiber module includes FA and optical fiber, FA is connected to one end of the optical fiber, and the quick pick-and-place fixture actually clamps the FA part of the FA optical fiber module.

[0048] The embodiment of the present application also discloses a high-precision optical module shell coupling device for performing shell coupling on an optical module. The optical module includes a tube shell, an FA optical fiber module and a chip. The chip is connected to the tube shell. The shell coupling is to couple the FA optical fiber module with the chip. Figure 4 As shown, it includes a fixed base 5, an optical module positioning and power supply component, an optical fiber adjustment component and a visual monitoring component.

[0049] When the optical module is coupled inside the shell, the optical module positioning and power supply components can realize the precise positioning, power supply and communication of the shell and tube; after the positioning of the shell and tube is completed, the optical fiber passes through the fiber hole of the shell and tube, and the optical fiber adjustment component realizes the clamping and position adjustment of the optical fiber. Through the visual monitoring component and the feedback of the optical power meter, the precise alignment and coupling of the FA optical fiber module and the chip are finally realized.

[0050] like Figure 4 As shown, the fixed base 5 is a basic component of the coupling device in the high-precision optical module shell, and is located at the bottom of the coupling device. The fixed base 5 is an optical platform with an array of threaded holes, which is used to fix the optical module positioning and power supply components, optical fiber adjustment components and visual monitoring components.

[0051] The optical module power supply and communication component includes a long-stroke slide 21, a lifting platform 22 and an optical module power supply box 23, which can realize the precise positioning, power supply and communication functions of the tube shell. The long-stroke slide 21 is fixed on the fixed base 5. The long-stroke slide 21 is provided with a base and a slider. The base can drive the slider to move horizontally, and its horizontal movement direction is close to or away from the optical fiber adjustment component. The base of the lifting platform 22 is fixedly connected to the slider of the long-stroke slide 21, which can realize the left and right movement of the lifting platform 22, which is convenient for loading and disassembly of the optical module; the optical module power supply box 23 is fixed on the top of the lifting platform 22, and the optical module power supply box 23 is driven by the lifting platform 22 to move up and down; the tube shell is fixed to the optical module power supply box 23, and the optical module power supply box 23 can realize the power supply and communication functions of the tube shell.

[0052] The optical fiber adjustment assembly includes a five-degree-of-freedom adjustment platform 31, a longitudinal support frame 32, a transverse support frame 33, and an optical fiber clamp 34. The optical fiber clamp 34 is the quick-pick-and-place clamp mentioned in the present patent, which can adjust the position and angle of the optical fiber. The five-degree-of-freedom adjustment platform 31 is fixed on the fixed base 5, and has the freedom of movement in the three directions of front and back, left and right, and up and down, and the freedom of rotation in the two directions of rolling and flipping; the longitudinal support frame 32 is fixed on the top of the five-degree-of-freedom adjustment platform 31, and a circular hole is provided on the longitudinal support frame 32, through which the optical fiber can pass when coupling to prevent the optical fiber from bending and twisting; the transverse support frame 33 is T-shaped and fixed on the upper part of the longitudinal support frame 32; the connecting part of the optical fiber clamp 34 is fixedly connected to the end of the transverse support frame 33, and is fixed directly above the optical module power supply box 23. The five-degree-of-freedom adjustment platform can move through the longitudinal support frame, the transverse support frame and the optical fiber clamp, thereby adjusting the position and angle of the optical fiber.

[0053] like Figure 5 As shown, three circular holes are designed on the side of the transverse support frame 33, which can be used to assist in fixing the longer optical fiber pigtails; the axis of the monitoring camera 44 maintains a certain angle with the optical module to prevent the field of view from being interfered.

[0054] During the coupling process, the visual monitoring component can monitor the relative position of the optical fiber and the optical module chip, and is mainly composed of a bracket base 41, a camera bracket 42, a camera adapter plate 43 and a monitoring camera 44. The camera bracket 42 is fixed to the fixed base 5 through the bracket base 41, and the monitoring camera 44 is fixed to the end of the camera bracket 42 through the camera adapter plate 43; the camera bracket 42 has four degrees of freedom for adjustment, which can adjust the monitoring position and monitoring angle of the monitoring camera. The angle between the monitoring camera 44 and the horizontal direction is 30°-60°, so that the position of the chip connected to the tube shell can be observed at the same time, and the position of the FA optical fiber module can also be observed, which is convenient for the precise coupling of the FA optical fiber module and the chip.

[0055] The optical module power supply box 23 is a power supply fixture for the optical module to be coupled in the shell, and is used to fix the coupling in the shell of the optical module. The optical module includes a tube shell 01 and a FA optical fiber module. The power supply fixture is used to fix the tube shell 01 so that the FA optical fiber module can be easily coupled with the tube shell 01. A chip 011 is installed on one side surface of the tube shell 01, and a Pin 012 is provided on at least one side of the tube shell 01. Figure 6 As shown, it includes a pressure cover 6, a supporting base 7, a circuit board 71, a power plug 72, a positive power supply line 721, a ground line 722, a high-level signal line 723, a low-level signal line 724, a base magnet 73 and a pressure cover magnet 61.

[0056] The tube shell 01 is placed on the supporting base 7. The pressing cover 6 can press the optical module tightly by relying on the attraction of the base magnet 73 and the pressing cover magnet 61. The circuit board 71 is provided with a spring probe to realize the power supply and communication of the optical module.

[0057] like Figure 6 As shown, the support base 7 is a basic component of the coupling power supply fixture in the optical module shell, which is used to connect and fix other components. The support base 7 is connected to the lifting platform 22. The support base 7 is provided with a square countersunk hole 74 that matches the shape and size of the outer edge of the tube shell 01. The four corners of the countersunk hole 74 match the four corners of the tube shell 01 to accurately position the tube shell 01. The square countersunk hole is provided with an avoidance groove at the edge position of the tube shell 01 where the pin needle 012 is provided to prevent the edge of the square countersunk hole from contacting the pin needle 012. The countersunk hole is provided with a plurality of grooves at the bottom position facing the pin needle 012. Each pin needle 012 corresponds to a groove. When the tube shell 01 is placed in the countersunk hole, each pin needle 012 is located in a groove. The groove separates each pin needle 012, which can effectively avoid the short circuit problem during the coupling process. The chip 011 is located on the upper surface of the tube shell 01, so that the FA optical fiber module can be aligned with the chip 011 from above for coupling.

[0058] The support base 7 includes a base and an intermediate base, the installation groove is provided on one side of the base, the intermediate groove is provided on the other side of the base, the intermediate groove is connected with the installation groove through a connecting hole, the intermediate base is installed at the intermediate groove position of the support base 7, the counterbore 74 is provided on the surface of one side of the intermediate base, and the intermediate base is provided with a plurality of partition plates arranged in sequence at the inner edge position of the counterbore 74 to form a comb-shaped tooth structure, and grooves are formed between the partition plates. This arrangement reduces the difficulty of processing.

[0059] The pressure cover 6 is hingedly mounted on the upper side of the support base 7. The pressure cover 6 has two states: open and closed. The pressure cover 6 is provided with a boss 62 corresponding to the position of the groove on the support base 7. When the pressure cover 6 is closed, the boss 62 presses the Pin 012 of the optical module. The support base 7 is provided with a mounting groove for mounting the circuit board 71 on the side away from the countersunk hole 74. The circuit board 71 is installed in the mounting groove. Four spring probes are provided on the circuit board 71. The positions of the four spring probes correspond to the four Pins respectively. The support base 7 is provided with a connecting hole. One end of the connecting hole is connected to the bottom of the groove where a Pin is located, and the other end is connected to the bottom of the mounting groove. Thus, the spring probe extends from the connecting hole to the bottom of the groove and stably contacts with the Pin. The middle part of the pressure cover 6 is provided with a mounting hole 63. When the pressure cover 6 is closed, the mounting hole 63 is located opposite to the chip 011, so that the chip 011 is completely exposed through the mounting hole 63, so that the tube shell 01 is fixed and the chip 011 is exposed at the same time, which is convenient for coupling the FA optical fiber module with the chip 011. The four corners of the tube shell 01 are connected with fixed legs 013, and the pressure cover 6 is provided with a clamping block 64, which corresponds to the position of the fixed legs. When the tube shell 01 is located in the countersunk hole, the clamping block presses the fixed legs 013 into the countersunk hole, thereby fixing the position of the tube shell 1.

[0060] like Fig. 9 As shown, a power supply plug 72 is provided on one side of the circuit board 71. There are four access points on the power supply plug 72, which are respectively connected to the corresponding power supply lines, namely, the positive power supply line 721, the ground line 722, the high-level signal line 723 and the low-level signal line 724. The positive power supply line 721, the ground line 722, the high-level signal line 723 and the low-level signal line 724 are connected to the optical module through the power supply plug 72 and the contact between the spring probe of the circuit board 71 and the corresponding Pin needle. The positive power supply line 721 and the ground line 722 realize the power supply of the internal circuit of the optical module, and the high-level signal line 723 and the low-level signal line 724 are used for the communication between the optical module and the outside world; the power supply fixture is made of insulating material as a whole, which can effectively avoid the short circuit of the optical module.

[0061] like Figure 7 As shown, the support base 7 is the main body structure of the coupling power supply fixture in the optical module shell, and the pressure cover 6 is connected to the support base 7 by a hinged manner. When in a closed state, the pressure cover 6 and the support base 7 fit each other to ensure that the optical module is pressed tightly; the positive power supply line 721 and the ground line 722 are introduced into the optical module through the power supply plug 72 to realize the power supply of the internal circuit of the optical module, and the high-level signal line 723 and the low-level signal line 724 are connected to the optical module through the power supply plug 72.
