[0021] For the convenience of those skilled in the art to understand, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present utility model.

[0022] As Figures 1 to 7 shown, a coupling machine for a light module FA double coupling table provided by the present utility model includes a machine table 1, two coupling tables 2 arranged side by side on the machine table 1, a duplex dispensing device 3 installed at the rear sides of the two coupling tables 2, a light curing mechanism 4 arranged on the duplex dispensing device 3, a vision positioning mechanism 5 arranged on the duplex dispensing device 3, and two coupling devices 6 respectively installed on the machine table 1. The two coupling tables 2 are located between the two coupling devices 6, and the two coupling devices 6 are respectively arranged in one-to-one correspondence with the two coupling tables 2. The coupling table 2 includes a positioning carrier 7 installed on the machine table 1, a support frame 8 arranged on one side of the positioning carrier 7, a base 9 arranged on the other side of the positioning carrier 7, a slide base 10 slidably connected to the base 9, a plug-in carrier 11 installed on the slide base 10, and a plug-in driving mechanism 12 installed on the base 9. The plug-in driving mechanism 12 is used to drive the slide base 10 to approach or move away from the positioning carrier 7. A positioning cavity 13 for carrying the PCB board 38 is recessed on the top surface of the positioning carrier 7, and an installation cavity 14 for loading the plug-in detector 37 is recessed on the top surface of the plug-in carrier 11; the support frame 8 is used to support the connectors of the light module FA; the light module FA is composed of a substrate, an optical fiber and a connector.

[0023] In practical applications, the plug-in detector 37 is installed in the installation cavity 14 of the plug-in stage 11. Two PCB boards 38 are respectively placed in the positioning cavities 13 of the positioning stages 7 of the two coupling stages 2. Each of the two coupling devices 6 picks up an optical module FA to the corresponding coupling stage 2, so that the substrate of the optical module FA and the coupling position of the PCB board 38 are preliminarily coupled. The support frame 8 supports the connector of the optical module FA. Then, the plug-in driving mechanism 12 drives the slide 10 together with the plug-in stage 11 and the plug-in detector 37 to move closer to the PCB board 38 until the terminals of the PCB board 38 are inserted into the plug-in detector 37 and electrically connected to the plug-in detector 37, so as to test the preliminarily coupled PCB board 38 to judge the qualification rate of the coupling. When the test is completed and the coupling is qualified, the plug-in driving mechanism 12 drives the slide 10 together with the plug-in stage 11 and the plug-in detector 37 to move away from the PCB board 38 and reset. Then, the two coupling devices 6 move the two optical modules FA away from the corresponding PCB boards 38. The duplex dispensing device 3 first drives the vision positioning mechanism 5 to perform vision positioning on the coupling positions of the two PCB boards 38. Then, the duplex dispensing device 3 dispenses optical glue on the coupling positions of the two PCB boards 38. Then, the two coupling devices 6 move the optical module FA to the corresponding coupling stage 2, so that the substrate of the optical module FA and the coupling position of the PCB board 38 after dispensing glue are finally coupled. The support frame 8 supports the connector of the optical module FA. Finally, the duplex dispensing device 3 drives the light curing mechanism 4 to move above the coupled PCB board 38 for light curing. The two coupling devices 6 of the present utility model work independently without affecting each other, and can couple two optical modules FA at one time, greatly improving the coupling efficiency. And during the coupling process, the plug-in detector 37 detects the qualification rate of the coupling, greatly improving the coupling quality.

[0024] In this embodiment, the coupling device 6 includes a coupling driving mechanism 15 installed on the machine table 1, and a substrate clamping mechanism 16 and a connector clamping mechanism 17 respectively installed at the driving end of the coupling driving mechanism 15. The substrate clamping mechanism 16 is used for clamping the substrate of the optical module FA, and the connector clamping mechanism 17 is used for clamping the connector of the optical module FA. In practical applications, the coupling driving mechanism 15 drives the substrate clamping mechanism 16 and the connector clamping mechanism 17 to move. The substrate clamping mechanism 16 clamps the substrate of the optical module FA, and the connector clamping mechanism 17 clamps the connector of the optical module FA to realize the picking and transferring of the optical module FA.

[0025] In this embodiment, the substrate clamping mechanism 16 includes a connecting arm 18 installed at the driving end of the coupling driving mechanism 15, a positioning driver 19 installed on the connecting arm 18, a fixing block 20 installed at the bottom end of the connecting arm 18, a positioning block 21 arranged on the front side of the bottom end face of the fixing block 20, a positioning arm 22 horizontally slidably connected to the connecting arm 18 and connected to the driving end of the positioning driver 19, and two clamping members 23 located on the left and right sides of the fixing block 20 and a clamping driver 24 for driving the two clamping members 23 to approach or separate from each other. The positioning arm 22 is located at the rear side of the fixing block 20. The bottom surface of the fixing block 20, the positioning block 21, the positioning arm 22, and the two clamping members 23 enclose a clamping space. Specifically, the positioning driver 19 can adopt a cylinder, and the clamping driver 24 can adopt a finger cylinder.

[0026] In practical applications, the coupling driving mechanism 15 drives the substrate clamping mechanism 16 to move to the substrate of the optical module FA, so that the substrate of the optical module FA is located within the clamping space. Then, the positioning driver 19 drives the positioning arm 22 to move closer to the fixing block 20, so that the positioning arm 22 pushes the substrate of the optical module FA against the fixing block 20. Then, the clamping driver 24 drives the two clamping members 23 to approach each other until the two clamping members 23 clamp the substrate of the optical module FA, so as to realize positioning and clamping of the substrate of the optical module FA.

[0027] In this embodiment, the clamping member 23 includes a mounting plate 25, a spring piece 26, and a clamping block 27 connected in sequence from top to bottom. The mounting plate 25 is installed on the side surface of the fixing block 20. There is an elastic deformation space 28 between the spring piece 26 and the side surface of the fixing block 20. There is a moving space 29 between the clamping block 27 and the side surface of the fixing block 20. The bottom surface of the fixing block 20, the positioning block 21, the positioning arm 22, and the clamping blocks 27 of the two clamping members 23 enclose a clamping space. The thicknesses of the spring pieces 26 of the two clamping members 23 are different. Specifically, the clamping driver 24 includes a telescopic cylinder 30, a shaft rod 31, and a pull rod 32. The cylinder body of the telescopic cylinder 30 is installed on the outer side surface of the clamping block 27 of one clamping member 23. The fixing block 20 and the clamping blocks 27 of the two clamping members 23 are coaxially provided with a through hole 33. One end of the shaft rod 31 is installed on the piston rod of the telescopic cylinder 30. The shaft rod 31 slidably passes through the through hole 33. The pull rod 32 is installed at the other end of the shaft rod 31. The pull rod 32 is used to abut against the outer side surface of the clamping block 27 of the other clamping member 23.

[0028] At the beginning, the piston rod of the telescopic cylinder 30 is in the extended state, and the clamping blocks 27 of the two clamping members 23 are opened (away from each other). When the piston rod of the telescopic cylinder 30 contracts and pulls the shaft rod 31 to move relative to the through hole 33, the pull rod 32 abuts against the clamping block 27 of the corresponding clamping member 23 and moves closer to the fixed block 20. The clamping block 27 of the other clamping member 23 will also move closer to the fixed block 20 under the pulling of the cylinder block of the telescopic cylinder 30 until the clamping blocks 27 of the two clamping members 23 clamp the substrate of the optical module FA. Since the thicknesses of the elastic pieces 26 of the two clamping members 23 are different, the elastic pieces 26 of the two clamping members 23 will undergo elastic deformation successively under the action of the force of the clamping driver 24, so that the clamping block 27 of one clamping member 23 first approaches one side of the substrate of the optical module FA and serves as the positioning reference for the substrate of the optical module FA, and the clamping block 27 of the other clamping member 23 then approaches the other side of the substrate of the optical module FA, causing the clamping blocks 27 of the two clamping members 23 to move closer to the fixed block 20 successively until the clamping blocks 27 of the two clamping members 23 stably clamp the substrate of the optical module FA in the clamping space.

[0029] In this embodiment, the joint clamping mechanism 17 includes an extension arm 34 installed on the connecting arm 18, a clamping cylinder 35 installed on the extension arm 34, and two clamping plates 36 respectively installed on the two clamping ends of the clamping cylinder 35. The clamping cylinder 35 is used to drive the two clamping plates 36 to approach or separate from each other. In practical applications, the clamping cylinder 35 drives the two clamping plates 36 to approach each other to clamp the joint of the optical module FA; the clamping cylinder 35 drives the two clamping plates 36 to separate from each other to loosen the joint of the optical module FA.

[0030] Specifically, the plugging and unplugging driving mechanism 12 can adopt a cylinder or a linear motor, the plugging and unplugging detector 37 can adopt a detection unit in the prior art, the duplex spot gluing device 3 is provided with two glue guns, and both the light curing mechanism 4 and the visual positioning mechanism 5 can adopt corresponding existing devices, which will not be elaborated here.

[0031] All the technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
