[0015] Preferably, limiting blocks are arranged on the upper sides of the U-shaped plates, guide rods three are fixedly installed at the upper ends of the limiting blocks, the upper ends of the guide rods three are slidably installed through a fixing plate, one end of the fixing plate is fixedly connected to the U-shaped plate, fourth springs are sleeved on the outer sides of the guide rods three, and the upper and lower ends of the fourth springs are respectively fixedly connected to the fixing plate and the limiting blocks.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the manipulator drives the manipulator support plate to descend through an external drive unit to grab the coupler below. When it descends to a position where the coupler is between the alignment plates and the grasping plates on both sides, the PLC controller on the manipulator support plate controls the motor to start, drives the screw rod to rotate, drives the grasping plates on both sides to approach each other, grabs the coupler, and the grasping plates also drive the guide rods one and the movable clamping plates on both sides to move synchronously. The arranged movable clamping plates will adaptively compress the first spring according to the slope of the upper and lower outer shells of the coupler and the length of the middle outer shell of the coupler, and completely clamp and fix the coupler, preventing the coupler from falling unstably during the clamping movement and ensuring stable clamping.

[0017] 2. In the present invention, the PLC controller controls the first electric push rod to push the first rack on one side to slide, drives the first gear to rotate, and then drives the first rack on the other side to move relatively, and then drives the alignment plates on both sides to move relatively synchronously, facilitating the automatic alignment of the clamped and fixed coupler, making the coupler located at the central position below the manipulator support plate, and ensuring the quality of subsequent pin insertion and welding of the coupler.

[0018] 3. In the present invention, when the coupler clamped by the movable clamping plates on both sides is offset and tilted, the first electric push rod is activated to drive the alignment plates on both sides to move away from each other, so that the alignment plates are loosened from the coupler. Then, the motor is activated to drive the gripping plates and the movable clamping plates on both sides to move away from each other, so that the movable clamping plates no longer contact and clamp the coupler. The movable clamping plate in the middle remains close to the middle shell of the coupler. At this time, under the action of gravity, the coupler will fall on the inner bottom end of the alignment plate. Then, the first electric push rod is activated to drive the alignment plates on both sides to move closer to each other. The alignment plates will drive the leveling strips on both sides to move synchronously. The leveling strips will slide outward in a direction away from each other on the alignment plate under the extrusion of the diamond-shaped blocks, stretching the second tension spring. The inner bottom ends of the set leveling strips and the inner bottom end of the alignment plate are located on the same horizontal line, which is convenient for sliding and leveling the bottom of the tilted coupler falling on the alignment plate, so as to keep the coupler in a horizontal state. Then, the motor is activated to drive the gripping plates and the movable clamping plates on both sides to move closer again, contact the coupler and adaptively compress the first spring, so as to ensure that when the coupler is clamped and fixed, it will not be in a tilted state, enabling the coupler pins to be aligned with the welding holes of the subsequent optoelectronic devices and smoothly inserted into the welding holes, which is beneficial to the normal insertion and welding of the subsequent coupler pins.

[0019] 4. In the present invention, when the coupler is transported to the upper side of the optoelectronic device by the manipulator, the second electric push rods on both sides are activated to drive the U-shaped plates on both sides to move closer to each other. After the coupler pins move between the anti-deformation strips on both sides inside the U-shaped plates, they stop. Then, the PLC controller is used to control and activate the third electric push rod to push the second rack on one side to move, driving the second gear to move. The second gear drives the second rack on the other side to move. At this time, the second racks on both sides drive the connecting pieces on both sides to move relatively. The connecting pieces drive the guide rods II and the anti-deformation strips on both sides to move relatively, clamping and fixing the coupler pins. When the manipulator drives the coupler and the coupler pins to move downward and insert into the welding holes of the optoelectronic device, the coupler pins will not be bent and deformed due to excessive downward pressure of the manipulator when inserted into the welding holes, thus ensuring the subsequent welding quality.

[0020] 5. In the present invention, when the connecting pieces on both sides move relatively, they will also drive the stable side plates on both sides to move relatively synchronously. The stable side plates on both sides will automatically be inserted into the corresponding slots. The set stable side plates are convenient for limiting the sides of the welding parts of the coupler pins, preventing the lower welding parts from being laterally bent and deformed due to excessive downward pressure of the manipulator on the coupler pins, thus ensuring the subsequent welding and processing quality.

[0021] 6. In the present invention, when the stable 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 stable side plate. The barbed structure of the reverse block will abut against the convex part at the welding position of the coupler pin, playing a limiting role on the coupler pin. It effectively prevents the situation that when the coupler pin is inserted into the welding hole, the downward pressure is too large, resulting in bending deformation at the connection between the coupler pin and the middle shell of the coupler. Even if there is deformation, it will only cause a small amount of deformation at the welding position of the coupler pin, and will not affect the subsequent welding melting effect.

[0022] 7. In the present invention, when the second electric push rod drives the U-shaped plate to approach the coupler pin, it will also drive the fixing plate, the third guide rod, and the limiting block to move synchronously. The inclined surface of the limiting block will contact the coupler pin and be squeezed by it, adaptively driving the third guide rod to move upward and compressing the fourth spring, so that the limiting block can stably abut against the upper end of the coupler pin. Cooperating with the reverse block, it effectively prevents the situation that during the process of inserting the coupler pin into the welding hole, excessive pressure causes deformation or even fracture of the coupler pin, thereby effectively improving the auxiliary effect during the processing of the coupler.

The outer sides of the upper and lower housings 2 of the coupler are arranged in an isosceles trapezoid shape on all four sides. Four coupler pins 3 are fixedly installed on the outer side of the middle housing 1 of the coupler, and a convex portion is provided at the lower part of the coupler pin 3; A coupler auxiliary processing device, comprising a manipulator support plate 4. The middle part of the upper end of the manipulator support plate 4 is connected to an external robotic arm; A grasping mechanism for grasping the coupler is also provided. The grasping mechanism includes a grasping plate 5 slidably installed through the left and right sides of the manipulator support plate 4. A screw rod 6 is threadedly installed at the upper end of the grasping plate 5. One end of the screw rod 6 is provided with a motor 7, and the motor 7 is fixedly connected to the upper end of the manipulator support plate 4. Three movable clamping plates 8 are equidistantly arranged on the side of the grasping plate 5 close to each other corresponding to the coupler. On the middle part of the lower end of the manipulator support plate 4, a rectifying plate 11 is symmetrically slidably installed in the front and back. One end of each of the movable clamping plates 8 away from each other is fixedly installed with a first guide rod 9, and the other end of the first guide rod 9 is respectively slidably installed through the grasping plates 5 on both sides. A first spring 10 is sleeved on the outer side of the first guide rod 9, and both ends of the first spring 10 are fixedly connected to the movable clamping plate 8 and the grasping plate 5 respectively. A first rack 12 is fixedly installed on the upper part of the rectifying plate 11. A first gear 13 is meshed between the first racks 12, and the first gear 13 is rotatably connected to the lower end of the manipulator support plate 4. A first electric push rod 14 is fixedly installed at the right end of the right first rack 12, and the first electric push rod 14 is fixedly connected to the lower end of the manipulator support plate 4. On the inner bottom end of the rectifying plate 11, leveling strips 15 are symmetrically slidably installed on the left and right. A second spring 16 is fixedly installed between the leveling strips 15. A diamond-shaped block 161 is fixedly installed at the lower end of the manipulator support plate 4 between the leveling strips 15; During operation, the manipulator drives the manipulator support plate 4 to descend through an external drive unit to grasp the coupler on the lower side. When it descends to a position where the coupler is between the alignment plates 11 and the gripping plates 5 on both sides, the PLC controller on the manipulator support plate 4 controls the motor 7 to start, driving the screw 6 to rotate, driving the gripping plates 5 on both sides to approach each other to grasp the coupler. The gripping plates 5 also drive the guide rods 9 and the movable clamping plates 8 on both sides to move synchronously. The set movable clamping plates 8 adaptively compress the first spring 10 according to the slope of the upper and lower housings 2 of the coupler and the length of the middle housing 1 of the coupler, completely clamping and fixing the coupler, preventing the coupler from falling unstably during the clamping movement, ensuring firm clamping. Then, the PLC controller controls the first electric push rod 14 to push the first rack 12 on one side to slide, driving the first gear 13 to rotate, and then driving the first rack 12 on the other side to move relatively, and further driving the alignment plates 11 on both sides to move synchronously relatively, facilitating the automatic alignment of the clamped and fixed coupler, making the coupler located at the central position under the manipulator support plate 4, ensuring the quality of the subsequent insertion and welding of the coupler pins 3. When the coupler clamped by the movable clamping plates 8 on both sides is offset and tilted, the first electric push rod 14 is started to drive the alignment plates 11 on both sides to move away from each other, loosening the alignment plates 11 from the coupler. Then, the motor 7 is started to drive the gripping plates 5 and the movable clamping plates 8 on both sides to move away from each other, so that the movable clamping plates 8 no longer contact and clamp the coupler. The movable clamping plate 8 in the middle remains close to the middle housing 1 of the coupler. At this time, the coupler will fall on the inner bottom end of the alignment plate 11 under the action of gravity. Then, the first electric push rod 14 is started to drive the alignment plates 11 on both sides to approach each other. The alignment plates 11 will drive the leveling strips 15 on both sides to move synchronously. The leveling strips 15 will slide outward in a direction away from each other on the alignment plate 11 under the extrusion of the diamond blocks 161, stretching the second spring 16. The inner bottom ends of the set leveling strips 15 and the inner bottom ends of the alignment plates 11 are on the same horizontal line, facilitating the sliding and leveling of the bottom of the tilted coupler falling on the alignment plate 11, so that the coupler is kept in a horizontal state. Then, the motor 7 is started to drive the gripping plates 5 and the movable clamping plates 8 on both sides to approach again, contact the coupler and adaptively compress the first spring 10, thus ensuring that the coupler will not be tilted when it is clamped and fixed, enabling the coupler pins 3 to be aligned with the welding holes of the subsequent optoelectronic devices and smoothly inserted into the welding holes, which is conducive to the normal insertion and welding of the subsequent coupler pins 3.

[0027] As an embodiment of the present invention, a protection mechanism is further provided for protecting the coupler pin 3 during welding after insertion. The protection mechanism includes four U-shaped plates 17 respectively arranged at the four corners of the lower side of the manipulator support plate 4 corresponding to the coupler pin 3. The upper ends of the U-shaped plates 17 are 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. Electric push rods two 18 are fixedly installed at the mutually remote ends of the two U-shaped plates 17 on the left and right sides. The electric push rods two 18 are fixedly connected to the lower end of the manipulator support plate 4. Anti-deformation strips 19 are symmetrically arranged inside the U-shaped plates 17. Guide rods two 20 are fixedly installed at the mutually remote ends of the anti-deformation strips 19. The guide rods two 20 respectively penetrate and are slidably mounted at both ends of the U-shaped plates 17. Connecting pieces 21 are fixedly installed at the other ends of the guide rods two 20. Rack two 22 are fixedly installed at one ends of the connecting pieces 21. The rack two 22 are slidably mounted on the U-shaped plates 17. A gear two 23 is meshed between the rack two 22. The gear two 23 is rotatably mounted on the outer side of the U-shaped plates 17. Electric push rods three 24 are fixedly installed on the outer side of the U-shaped plates 17 corresponding to the rack two 22. The telescopic ends of the electric push rods three 24 are fixedly connected to one side of the rack two 22. Stable side plates 25 are fixedly installed at the mutually adjacent ends of the connecting pieces 21 in a staggered manner. Slots 26 are respectively formed in the connecting pieces 21 corresponding to the stable side plates 25. A reverse block 27 penetrates and is slidably mounted on one side of the stable side plate 25. A spherical rod 28 is fixedly installed at one end of the reverse block 27. A connecting plate 29 penetrates and is slidably mounted in the middle of the spherical rod 28. The connecting plate 29 is fixedly connected to the stable side plate 25. 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. Limit blocks 31 are respectively arranged on the upper sides of the U-shaped plates 17. Guide rods three 32 are fixedly installed at the upper ends of the limit blocks 31. The upper ends of the guide rods three 32 penetrate and are slidably mounted with a fixing plate 33. One end of the fixing plate 33 is fixedly connected to the U-shaped plate 17. Springs four 34 are sleeved on the outer sides of the guide rods three 32. The upper and lower ends of the springs four 34 are respectively fixedly connected to the fixing plate 33 and the limit blocks 31; During operation, when the coupler is transported to the upper side of the optoelectronic device by the manipulator, the electric push rods II 18 on both sides are activated to drive the U-shaped plates 17 on both sides to approach each other, causing the coupler pins 3 to move between the anti-deformation strips 19 on both sides inside the U-shaped plates 17 and then stop. Then, the electric push rod III 24 is controlled by the PLC controller to push the rack II 22 on one side to move, driving the gear II 23 to move, and the gear II 23 drives the rack II 22 on the other side to move. At this time, the racks II 22 on both sides drive the connecting pieces 21 on both sides to move relatively, and the connecting pieces 21 drive the guide rods II 20 and the anti-deformation strips 19 on both sides to move relatively, clamping and fixing the coupler pins 3. When the manipulator drives the coupler and the coupler pins 3 to move downward and insert into the welding holes of the optoelectronic device, the coupler pins 3 will not be bent and deformed due to excessive downward pressure of the manipulator when inserted into the welding holes, thus ensuring the subsequent welding quality. When the connecting pieces 21 on both sides move relatively, they will also drive the stable side plates 25 on both sides to move relatively synchronously. The stable side plates 25 on both sides will automatically be inserted into the corresponding slots 26. The provided stable side plates 25 facilitate the lateral limitation of the welding part of the coupler pins 3, preventing the coupler pins 3 from being laterally bent and deformed due to excessive downward pressure of the manipulator, thus ensuring the subsequent welding and processing quality. When one of the stable side plates 25 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 pushed by the inner wall of the slot 26 to drive the reverse block 27 to protrude from the stable side plate 25. The barbed structure of the reverse block 27 will abut and latch on the protruding part of the welding part of the coupler pins 3, playing a limiting role on the coupler pins 3, effectively preventing the coupler pins 3 from being bent and deformed at the connection between the coupler pins 3 and the middle shell 1 of the coupler when inserted into the welding hole with excessive downward pressure. Even if there is deformation, it will only cause a small amount of deformation in the welding part of the coupler pins 3, without affecting the subsequent welding and melting effect. When the electric push rod II 18 drives the U-shaped plate 17 to approach the coupler pins 3, it will also drive the fixing plate 33, the guide rod III 32, and the limit block 31 to move synchronously. The inclined surface of the limit block 31 will contact the coupler pins 3 and be squeezed by them, adaptively driving the guide rod III 32 to move upward and compressing the spring IV 34, so that the limit block 31 can stably abut on the upper end of the coupler pins 3. Cooperating with the reverse block 27, it effectively prevents the coupler pins 3 from being deformed or even broken due to excessive pressure during the process of inserting the coupler pins 3 into the welding hole, thus effectively improving the auxiliary effect during the processing of the coupler.

[0028] Working principle: When the present invention is in use, the manipulator is driven by an external drive unit to lower the manipulator support plate 4 to grasp the coupler on the lower side. When it descends to a position where the coupler is between the alignment plates 11 and the grasping plates 5 on both sides, the PLC controller on the manipulator support plate 4 controls the motor 7 to start, driving the screw rod 6 to rotate, driving the grasping plates 5 on both sides to approach each other to grasp the coupler. The grasping plates 5 also drive the guide rods 9 and the movable clamping plates 8 on both sides to move synchronously. The set movable clamping plates 8 will adaptively compress the first spring 10 according to the slope of the upper and lower outer shells 2 of the coupler and the length of the middle outer shell 1 of the coupler, completely clamping and fixing the coupler to prevent the coupler from falling unstably during the clamping movement, ensuring firm clamping. Then, the PLC controller controls the first electric push rod 14 to push the first rack 12 on one side to slide, driving the first gear 13 to rotate, and then driving the first rack 12 on the other side to move relatively, and then driving the alignment plates 11 on both sides to move synchronously relatively, facilitating the automatic alignment of the clamped and fixed coupler, making the coupler located at the central position under the manipulator support plate 4, ensuring the quality of the subsequent insertion and welding of the coupler pins 3. When the coupler clamped by the movable clamping plates 8 on both sides is offset and tilted, the first electric push rod 14 is started to drive the alignment plates 11 on both sides to move away from each other, loosening the alignment plates 11 from the coupler. Then the motor 7 is started to drive the grasping plates 5 and the movable clamping plates 8 on both sides to move away from each other, so that the movable clamping plates 8 no longer contact and clamp the coupler. The movable clamping plate 8 in the middle remains close to the middle outer shell 1 of the coupler. At this time, the coupler will fall onto the inner bottom end of the alignment plate 11 under the action of gravity. Then the first electric push rod 14 is started to drive the alignment plates 11 on both sides to approach each other. The alignment plates 11 will drive the leveling strips 15 on both sides to move synchronously. The leveling strips 15 will slide outward in a direction away from each other on the alignment plate 11 under the extrusion of the diamond-shaped blocks 161, stretching the second spring 16. The inner bottom ends of the set leveling strips 15 are on the same horizontal line as the inner bottom end of the alignment plate 11, facilitating the sliding and leveling of the bottom of the tilted coupler falling on the alignment plate 11, so that the coupler is kept in a horizontal state. Then the motor 7 is started to drive the grasping plates 5 and the movable clamping plates 8 on both sides to approach again, contact with the coupler and adaptively compress the first spring 10, thus ensuring that when the coupler is clamped and fixed, it will not be in a tilted state, enabling the coupler pins 3 to be aligned with the welding holes of the subsequent optoelectronic device and smoothly inserted into the welding holes, which is beneficial to the normal insertion and welding of the subsequent coupler pins 3. When the coupler is transported by the manipulator to the upper side of the optoelectronic device, the two sides of the second electric push rod 18 are started to drive the U-shaped plates 17 on both sides to approach each other, and the coupler pins 3 stop moving between the anti-deformation strips 19 on both sides inside the U-shaped plates 17. Then, through the PLC controller, the third electric push rod 24 is controlled to start to push the second rack 22 on one side to move, driving the second gear 23 to move. The second gear 23 drives the second rack 22 on the other side to move. At this time, the second racks 22 on both sides drive the connecting pieces 21 on both sides to move relatively,The connecting piece 21 drives the two guide rods 20 and the anti-deformation strips 19 on both sides to move relatively, clamping and fixing the coupler pin 3. When the manipulator drives the coupler and the coupler pin 3 to move downward and insert into the welding hole of the optoelectronic device, the coupler pin 3 will not be bent and deformed due to excessive downward pressure of the manipulator when the coupler pin 3 is inserted into the welding hole, thus ensuring the subsequent welding quality. When the two connecting pieces 21 move relatively, they will also drive the two stable side plates 25 on both sides to move relatively synchronously. The two stable side plates 25 will automatically be inserted into the corresponding slots 26. The provided stable side plates 25 facilitate the lateral limitation of the welding part of the coupler pin 3, preventing the coupler pin 3 from being laterally bent and deformed due to excessive downward pressure of the manipulator, thus ensuring the subsequent welding and processing quality. When one of the stable side plates 25 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 extruded by the inner wall of the slot 26 to push the reverse block 27 to protrude from the stable side plate 25. The barbed structure of the reverse block 27 will abut and be stuck at the convex part of the welding part of the coupler pin 3, playing a limiting role on the coupler pin 3, effectively preventing the coupler pin 3 from being bent and deformed at the connection with the middle shell 1 of the coupler when the downward pressure is too large when the coupler pin 3 is inserted into the welding hole. Even if there is deformation, it will only cause a small amount of deformation in the welding part of the coupler pin 3 and will not affect the subsequent welding and melting effect. When the second electric push rod 18 drives the U-shaped plate 17 to approach the coupler pin 3, it will also drive the fixing plate 33, the third guide rod 32 and the limiting block 31 to move synchronously. The inclined surface of the limiting block 31 will contact the coupler pin 3 and be extruded by it, adaptively driving the third guide rod 32 to move upward and compressing the fourth spring 34, so that the limiting block 31 can stably abut on the upper end of the coupler pin 3. Cooperating with the reverse block 27, it effectively prevents the coupler pin 3 from being deformed or even broken due to excessive pressure during the process of inserting the coupler pin 3 into the welding hole, thus effectively improving the auxiliary effect during the processing of the coupler.
