[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, the manipulator drives the manipulator support plate to descend through an external drive unit to grab the coupler on the lower side. When it descends to the position between the return plate and the grab plate on both sides of the coupler, the PLC controller on the manipulator support plate controls the motor to start, drives the screw to rotate, drives the grab plates on both sides to approach each other, and grabs the coupler. The grab plates will also drive the guide rods and movable splints on both sides to move synchronously. The arranged movable splint will adapt the compression spring according to the inclination of the upper and lower shells of the coupler and the length of the middle shell of the coupler to completely clamp and fix the coupler, preventing the coupler from becoming unstable and falling during the clamping movement, thereby ensuring stable clamping.

[0022] 2. In the present invention, the PLC controller controls the electric push rod to push the rack on one side to slide, drive the gear to rotate, and then drive the rack on the other side to move relative to each other, and then drive the correction plates on both sides to move synchronously relative to each other, so as to facilitate the automatic correction of the clamped coupler, so that the coupler is located at the center position of the lower side of the manipulator support plate, ensuring the quality of subsequent coupler pin plug-in welding.

[0023] 3. In the present invention, when the couplers clamped by the movable splints on both sides are offset and tilted, the electric push rod is started to drive the return plates on both sides away from each other, so that the return plates and the couplers are loosened, and then the motor is started to drive the grab plates and the movable splints on both sides away from each other, so that the movable splints no longer contact the clamping couplers, and the middle movable splint and the middle shell of the coupler are kept close to each other. At this time, the coupler will fall on the inner bottom end of the return plate under the action of gravity, and then the electric push rod is started to drive the return plates on both sides close to each other. The return plate will drive the paving strips on both sides to move synchronously, and the paving strips will be squeezed on the return plate by the diamond blocks. The two levers are moved in opposite directions so that the springs can move in opposite directions, and the springs can be stretched so that the lever ...

[0024] 4. In the present invention, when the coupler is transferred to the upper side of the photoelectric device by the robot, the electric push rods 2 on both sides are started to drive the U-shaped plates on both sides to approach each other, so that the coupler pins move between the anti-deformation strips on both sides in the U-shaped plate and then stop, and then the electric push rods 3 are started by the PLC controller to push the rack 2 on one side to move, drive the gear 2 to move, and the gear 2 drives the rack 2 on the other side to move. At this time, the racks 2 on both sides drive the connecting pieces on both sides to move relative to each other, and the connecting pieces drive the guide rods 2 and the anti-deformation strips on both sides to move relative to each other, clamping and fixing the coupler pins, so that the robot can drive the coupler and the coupler pins to move downward and insert them into the welding hole of the photoelectric device. The coupler pins will not be bent and deformed due to excessive downward pressure from the robot, thereby ensuring the subsequent welding quality.

[0025] 5. In the present invention, when the connecting pieces on both sides move relative to each other, the stabilizing side plates on both sides will also be driven to move synchronously relative to each other. The stabilizing side plates on both sides will be automatically inserted into the corresponding slots. The provided stabilizing side plates are convenient for limiting the sides of the welding parts of the coupler pins, preventing the coupler pins from being subjected to excessive downward pressure from the robot, resulting in lateral bending and deformation of the lower welding parts, thereby ensuring the quality of subsequent welding processing.

[0026] 6. In the present invention, when the stabilizing side plate on one side is inserted into the corresponding slot, it will also drive the reverse block, the spherical rod and the connecting plate to move synchronously. The spherical rod will be squeezed by the inner wall of the slot to push the reverse block out of the stabilizing side plate. The barbed structure of the reverse block will abut against the raised part of the welding part of the coupler pin, which will limit the coupler pin and effectively prevent the coupler pin from being inserted into the welding hole due to excessive downward pressure, resulting in bending deformation at the connection between the coupler pin and the middle shell of the coupler. Even if deformation occurs, it will only cause a small deformation of the welding part of the coupler pin, which will not affect the subsequent welding melting effect.

[0027] 7. In the present invention, when the electric push rod 2 drives the U-shaped plate to approach the coupler pin, it will also drive the fixed plate, the guide rod 3 and the limit block to move synchronously. The inclined surface of the limit block will contact the coupler pin and be squeezed by it, adaptively driving the guide rod 3 to move upward, compressing the spring 4, so that the limit block can stably abut against the upper end of the coupler pin, cooperating with the reverse block, effectively preventing the coupler pin from being deformed or even broken due to excessive pressure during the process of inserting the coupler pin into the welding hole, thereby effectively improving the auxiliary role during the coupler processing.

[0049] A coupler auxiliary processing device includes a manipulator support plate 4, the middle part of the upper end of the manipulator support plate 4 is connected to the external manipulator arm; a grabbing mechanism for grabbing the coupler is also provided, the grabbing mechanism includes a grabbing plate 5 slidably installed on the left and right sides of the manipulator support plate 4, a screw 6 is threadedly installed on the upper end of the grabbing plate 5, a motor 7 is provided at one end of the screw 6, the motor 7 is fixedly connected to the upper end of the manipulator support plate 4, and three movable splints 8 are provided at equal intervals corresponding to the coupler on the side where the grabbing plates 5 are close to each other, and a return plate 11 is slidably installed symmetrically in the middle of the lower end of the manipulator support plate 4, and a guide rod 9 is fixedly installed on the end away from each other, and the other end of the guide rod 9 is respectively penetrated It is slidably mounted on the grab plates 5 on both sides, and a spring 10 is sleeved on the outer side of the guide rod 9. The two ends of the spring 10 are fixedly connected to the movable splint 8 and the grab plate 5 respectively. A rack 12 is fixedly mounted on the upper part of the return plate 11, and a gear 13 is engaged between the racks 12. The gear 13 is rotatably connected to the lower end of the manipulator support plate 4. An electric push rod 14 is fixedly mounted on the right end of the rack 12 on the right side, and the electric push rod 14 is fixedly connected to the lower end of the manipulator support plate 4. Leveling strips 15 are symmetrically slidably mounted on the inner bottom end of the return plate 11. Springs 2 16 are fixedly mounted between the leveling strips 15. The lower end of the manipulator support plate 4 is located between the leveling strips 15 and is fixedly mounted with a diamond block 161;

[0050] During operation, the manipulator drives the manipulator support plate 4 to descend through an external drive unit to grab the coupler on the lower side. When it descends to between the return plate 11 and the grab plate 5 on both sides of the coupler, the PLC controller on the manipulator support plate 4 controls the motor 7 to start, drives the screw 6 to rotate, drives the grab plates 5 on both sides to approach each other, and grabs the coupler. The grab plate 5 will also drive the guide rods 9 and movable splints 8 on both sides to move synchronously. The movable splint 8 will adaptively compress the spring 10 according to the inclination of the upper and lower housings 2 of the coupler and the length of the middle housing 1 of the coupler to completely clamp the coupler. The PLC controller controls the electric push rod 14 to push the rack 12 on one side to slide, drive the gear 13 to rotate, and then drive the rack 12 on the other side to move relative to each other, which will drive the correction plates 11 on both sides to move synchronously relative to each other, so as to facilitate the automatic correction of the clamped and fixed coupler, so that the coupler is located at the center position of the lower side of the manipulator support plate 4, ensuring the quality of the subsequent coupler pin 3 plug-in welding. When the coupler clamped by the movable splints 8 on both sides is offset and tilted, the electric push rod 14 is started to drive the two sides. The return plates 11 move away from each other, causing the return plates 11 and the coupler to loosen, and then the motor 7 is started to drive the grab plates 5 and the movable splints 8 on both sides to move away from each other, so that the movable splints 8 no longer contact the clamping coupler, and the middle movable splint 8 is kept close to the middle shell 1 of the coupler. At this time, the coupler will fall on the inner bottom end of the return plate 11 under the action of gravity, and then the electric push rod 14 is started to drive the return plates 11 on both sides to move closer to each other. The return plate 11 will drive the paving strips 15 on both sides to move synchronously, and the paving strips 15 will slide outward on the return plate 11 in a direction away from each other under the squeezing action of the diamond block 161. The inner bottom end of the tension spring 2 16 and the leveling strip 15 are located on the same horizontal line as the inner bottom end of the correction plate 11, so as to facilitate sliding and leveling the bottom of the coupler that falls on the correction plate 11 and tilts, thereby keeping the coupler in a horizontal state, and then starting the motor 7 to drive the grab plates 5 and the movable splints 8 on both sides to approach again, contacting with the coupler and adaptively squeezing the spring 10, thereby ensuring that the coupler will not be tilted when clamped and fixed, so that the coupler pin 3 can be aligned with the subsequent optoelectronic device welding hole and smoothly plugged into the welding hole, which is conducive to the normal plugging and welding of the subsequent coupler pin 3.

[0051] As an embodiment of the present invention, a protective mechanism is also provided for protecting the coupler pin 3 during welding after insertion. The protective mechanism includes four U-shaped plates 17 corresponding to the coupler pin 3 arranged at the four corners of the lower side of the manipulator support plate 4. The upper end of the U-shaped plate 17 is slidably mounted on the manipulator support plate 4, and the two U-shaped plates 17 on the left and right sides are fixed to each other. The ends of the two U-shaped plates 17 on the left and right sides that are away from each other are fixedly mounted with an electric push rod 2 18, and the electric push rod 2 18 is fixedly connected to the lower end of the manipulator support plate 4. The U-shaped plate 17 is symmetrically provided with anti-deformation strips 19 inside. The anti-deformation strips 19 are fixedly installed with guide rods 20 at one end away from each other. The guide rods 20 are respectively slidably installed on both ends of the U-shaped plate 17. The other end of the guide rods 20 is fixedly installed with connecting pieces 21. One end of the connecting piece 21 is fixedly installed with racks 22. The racks 22 are slidably installed on the U-shaped plate 17. There are gears 23 meshing between the racks 22. The gears 23 are rotatably installed on the outside of the U-shaped plate 17, and the outside of the U-shaped plate 17 is fixed with a connecting piece 21. The corresponding rack 22 on the side is fixedly installed with an electric push rod 3 24, and the telescopic end of the electric push rod 3 24 is fixedly connected to the rack 22 on one side. The connecting pieces 21 are fixedly installed with a stable side plate 25 on one end close to each other. The corresponding stable side plates 25 on the connecting pieces 21 are provided with slots 26. A reverse block 27 is slidably installed on the stable side plate 25 on one side. A round ball rod 28 is fixedly installed on one end of the reverse block 27. A connecting plate 29 is slidably installed on the middle part of the connecting plate 28. The connecting plate 29 is connected to the stable side plate 25. The side plates 25 are fixedly connected, and a spring three 30 is sleeved on the outer side of the spherical rod 28. The two ends of the spring three 30 are respectively fixedly connected to the connecting plate 29 and the reverse block 27. The upper side of the U-shaped plate 17 is provided with a limit block 31, and the upper end of the limit block 31 is fixedly installed with a guide rod three 32. The upper end of the guide rod three 32 is slidably installed with a fixed plate 33. One end of the fixed plate 33 is fixedly connected to the U-shaped plate 17. The outer side of the guide rod three 32 is sleeved with a spring four 34. The upper and lower ends of the spring four 34 are respectively fixedly connected to the fixed plate 33 and the limit block 31;

[0052] During operation, when the coupler is transferred to the upper side of the photoelectric device by the manipulator, the electric push rods 2 18 on both sides are started to drive the U-shaped plates 17 on both sides to approach each other, so that the coupler pin 3 moves between the anti-deformation strips 19 on both sides in the U-shaped plate 17 and stops. Then, the electric push rod 3 24 is started by the PLC controller to push the rack 2 22 on one side to move, drive the gear 2 23 to move, and the gear 2 23 drives the rack 2 22 on the other side to move. At this time, the racks 22 on both sides drive the connecting pieces 21 on both sides to move relative to each other, and the connecting pieces 21 drive the guide rods 20 and the anti-deformation strips 19 on both sides to move relative to each other, clamping and fixing the coupler pin 3, so that the manipulator can drive the coupler and When the coupler pin 3 moves downward and is inserted into the welding hole of the optoelectronic device, the coupler pin 3 will not be bent or deformed due to excessive downward pressure from the manipulator, thereby ensuring the subsequent welding quality. When the connecting pieces 21 on both sides move relative to each other, the stabilizing side plates 25 on both sides will also be driven to move synchronously relative to each other. The stabilizing side plates 25 on both sides will be automatically inserted into the corresponding slots 26. The provided stabilizing side plates 25 are convenient for limiting the sides of the welding part of the coupler pin 3, preventing the coupler pin 3 from being subjected to excessive downward pressure from the manipulator, resulting in the lateral bending and deformation of the lower welding part, thereby To ensure the quality of subsequent welding processing, when the stabilizing side plate 25 on one side is inserted into the corresponding slot 26, it will also drive the reverse block 27, the spherical rod 28 and the connecting plate 29 to move synchronously. The spherical rod 28 will be squeezed by the inner wall of the slot 26 to push the reverse block 27 out of the stabilizing side plate 25. The barbed structure of the reverse block 27 will abut against the raised part of the welding part of the coupler pin 3, which will limit the coupler pin 3 and effectively prevent the coupler pin 3 from being inserted into the welding hole. The downward pressure is too large, which will cause the connection between the coupler pin 3 and the middle housing 1 of the coupler to bend and deform. Even if deformation occurs, it will only cause the welding part of the coupler pin 3 to bend. The occurrence of a small deformation will not affect the subsequent welding melting effect. When the electric push rod 2 18 drives the U-shaped plate 17 to approach the coupler pin 3, it will also drive the fixed plate 33, the guide rod 3 32 and the limit block 31 to move synchronously. The inclined surface of the limit block 31 will contact the coupler pin 3 and be squeezed by it, adaptively driving the guide rod 3 32 to move upward, compressing the spring 4 34, so that the limit block 31 can stably abut against the upper end of the coupler pin 3, and cooperate with the reverse block 27 to effectively prevent the coupler pin 3 from being inserted into the welding hole due to excessive pressure, thereby effectively improving the auxiliary role during the coupler processing.

[0053] Working principle:

[0054] When the present invention is in use, the manipulator drives the manipulator support plate 4 to descend through the external drive unit to grab the coupler on the lower side. When it descends to between the return plate 11 and the grab plate 5 on both sides of the coupler, the PLC controller on the manipulator support plate 4 controls the motor 7 to start, drives the screw 6 to rotate, drives the grab plates 5 on both sides to approach each other, and grabs the coupler. The grab plate 5 will also drive the guide rods 9 and movable splints 8 on both sides to move synchronously. The movable splint 8 will adapt the compression spring 10 according to the inclination of the upper and lower shells 2 of the coupler and the length of the middle shell 1 of the coupler to completely clamp and fix the coupler, preventing the coupler from being unstable and falling during the clamping movement, thereby ensuring stable clamping. Then the PLC controls The robot controls the electric push rod 14 to push the rack 12 on one side to slide, driving the gear 13 to rotate, and then driving the rack 12 on the other side to move relative to each other, which will drive the return plates 11 on both sides to move synchronously relative to each other, so as to facilitate the automatic correction of the clamped coupler, so that the coupler is located in the center position of the lower side of the manipulator support plate 4, ensuring the quality of subsequent coupler pin 3 plug-in welding. When the coupler clamped by the movable splints 8 on both sides is offset and tilted, the electric push rod 14 is started to drive the return plates 11 on both sides away from each other, so that the return plates 11 and the coupler are loosened, and then the motor 7 is started to drive the grab plates 5 and the movable splint 8 on both sides away from each other, so that the movable splint 8 no longer contacts the clamped coupler, and the middle movable splint 8 is in contact with the middle of the coupler. The outer shell 1 remains in a close state. At this time, the coupler will fall on the inner bottom end of the correction plate 11 under the action of gravity, and then the electric push rod 14 will be started to drive the correction plates 11 on both sides to move closer to each other. The correction plate 11 will drive the paving strips 15 on both sides to move synchronously. The paving strips 15 will be squeezed by the diamond block 161 and will slide outward in the direction away from each other on the correction plate 11, stretching the spring 2 16. The inner bottom end of the paving strip 15 and the inner bottom end of the correction plate 11 are located on the same horizontal line, which is convenient for sliding and paving the bottom of the coupler that falls on the correction plate 11, thereby keeping the coupler in a horizontal state. Then the motor 7 will be started to drive the grab plates 5 and the movable splint 8 on both sides to move closer again, contacting the coupler and adaptively squeezing the spring 1 0, thereby ensuring that the coupler will not be tilted when it is clamped and fixed, so that the coupler pin 3 can be aligned with the subsequent optoelectronic device welding hole and smoothly plugged into the welding hole, which is conducive to the normal plugging and welding of the subsequent coupler pin 3. When the coupler is transferred to the upper side of the optoelectronic device by the robot, the electric push rods 2 18 on both sides are started to drive the U-shaped plates 17 on both sides to approach each other, so that the coupler pin 3 moves between the anti-deformation strips 19 on both sides of the U-shaped plate 17 and then stops. Then, the electric push rod 3 24 is started through the PLC controller to push the rack 2 22 on one side to move, drive the gear 2 23 to move, and the gear 2 23 drives the rack 2 22 on the other side to move. At this time, the racks 22 on both sides drive the connecting pieces 21 on both sides to move relative to each other.The connecting piece 21 drives the guide rod 20 and the anti-deformation strip 19 on both sides to move relative to each other, clamping and fixing the coupler pin 3, so that the manipulator can drive the coupler and the coupler pin 3 to move downward and insert them into the welding hole of the optoelectronic device. The coupler pin 3 will not be bent or deformed due to excessive downward pressure from the manipulator, thereby ensuring the subsequent welding quality. When the connecting pieces 21 on both sides move relative to each other, the stabilizing side plates 25 on both sides will also be driven to move relative to each other synchronously. The stabilizing side plates 25 on one side will automatically be inserted into the corresponding slots 26. The stabilizing side plates 25 provided are convenient for limiting the side edges of the welding parts of the coupler pins 3, preventing the coupler pins 3 from being subjected to excessive downward pressure from the manipulator, resulting in lateral bending and deformation of the lower welding parts, thereby ensuring the quality of subsequent welding processing. When the stabilizing side plates 25 on one side are inserted into the corresponding slots 26, they will also drive the reverse block 27, the ball rod 28 and the connecting plate 29 to move synchronously. The ball rod 28 will be squeezed by the inner wall of the slot 26 to push the reverse block 27, the ball rod 28 and the connecting plate 29 to move synchronously. The forward block 27 extends from the stable side plate 25, and the barbed structure of the reverse block 27 abuts against the raised portion of the welding portion of the coupler pin 3, thereby limiting the coupler pin 3 and effectively preventing the coupler pin 3 from being inserted into the welding hole due to excessive downward pressure, thereby causing the coupler pin 3 and the coupler middle housing 1 to bend and deform. Even if deformation occurs, it will only cause a small deformation of the welding portion of the coupler pin 3, which will not affect the subsequent welding melting effect. When the electric push rod 2 18 drives the U-shaped plate 17 toward the coupler pin When the guide rod 3 approaches, it will also drive the fixed plate 33, the guide rod 32 and the limit block 31 to move synchronously. The inclined surface of the limit block 31 will contact the coupler pin 3 and be squeezed by it, adaptively driving the guide rod 3 32 upward, compressing the spring 4 34, so that the limit block 31 can stably abut against the upper end of the coupler pin 3. Cooperating with the reverse block 27, it effectively prevents the deformation or even breakage of the coupler pin 3 caused by excessive pressure during the insertion of the coupler pin 3 into the welding hole, thereby effectively improving the auxiliary function during the coupler processing.
