[0008] Preferably, a passive correction oblique block is fixedly installed at the middle part of one end of the limit plates close to each other, and an active correction plate is slidably installed symmetrically on the left and right sides of one end of the limit plates close to each other.

[0009] Preferably, a spring 2 is fixedly mounted on one end of the active correction plate, and the other end of the spring 2 is fixedly mounted on the limit plate.

[0010] Preferably, a steel wire rope 1 is fixedly mounted on one end of the active correction plate, a winding roller 1 is fixedly wound around the other end of the steel wire rope 1, and the lower end of the winding roller 1 is rotatably mounted on two limit plates.

[0011] Preferably, a second roller is fixedly mounted on the upper end of the first roller, a second steel wire rope is fixedly wound on the outer side of the second roller, and movable magnetic strips are fixedly mounted on the ends of the second steel wire ropes that are away from each other.

[0012] Preferably, the active magnetic strips are provided with passive magnetic strips at the lower sides of the ends away from each other, and the lower ends of the passive magnetic strips are fixedly mounted on the linear guide rails.

[0013] Preferably, the limit block strips are slidably installed symmetrically on the left and right sides of the middle part of the limit plate, and spring three is fixedly installed on the outer side of the limit block strip, and the other end of the spring three is fixedly installed on the limit plate, and a passive inclined plate is fixedly installed on the corresponding limit block strip at one end of the passive magnetic strip that is close to each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the linear guide rail transports the preliminary assembled combination of the connector housing and the plug pin to the lower side of the assembly plate one by one. When the preliminary assembled combination of the connector housing and the plug pin moves to the bottom of the assembly plate, the linear guide rail stops temporarily, and the hydraulic cylinder is started to push the adjustment frame down. The adjustment frame pushes the connecting plate and the assembly plate down synchronously. The through hole on the assembly plate is aligned with the upper end of the plug pin, and the plug pin is extruded and assembled so that the plug pin can be firmly inserted into the coupler housing, thereby improving the assembly quality of the coupler terminal and ensuring the good conductivity of the coupler terminal.

[0017] 2. In the present invention, the starting motor drives the screw to rotate, and the screw drives the connecting plate to move back and forth on the adjusting frame. The connecting plate also drives the assembly pressing plate to move back and forth, which is convenient for adjusting the assembly pressing plates of different specifications to press and assemble the pins according to the sizes of different pins. It has a wide adaptability, reduces manual disassembly and replacement of the assembly pressing plates, and improves the efficiency of assembly.

[0018] 3. In the present invention, when the adjustment frame descends, the connecting strips and the limit plates on both sides will also be driven to descend synchronously, and the limit plates on both sides will move to the front and rear sides of the pins in advance. As the adjustment frame and the connecting strips continue to descend, the connecting strips on both sides will be pushed to move in the direction of approaching each other on the adjustment frame under the action of the oblique strips. The compression spring 1 will also drive the limit plates on both sides to move in the direction of approaching each other. The limit plates on both sides will gradually approach and fit the pins, which is conducive to keeping the front and rear tilted pins in a vertical state, avoiding the situation where the pins are tilted and cause the coupler terminal assembly failure or poor assembly quality, thereby improving the assembly quality of the coupler terminals.

[0019] 4. In the present invention, when the limit plate and the connecting strip descend, the active magnetic strip will also be driven to descend synchronously. When the active magnetic strip descends to the rear side close to the passive magnetic strip, the active magnetic strip will be pulled to slide on the connecting strip in the direction away from each other under the action of magnetic attraction. The second wire rope is used to pull the second roller and the first roller to rotate on the limit plate. The first roller reels up the first wire rope on both sides, which will drive the active correction plates on both sides to slide on the limit plate in the direction close to each other. The second spring is compressed, which is conducive to correcting the pins tilted to the left and right directions again, so that the pins and the assembly pressure plate remain in a vertical state, which is convenient for improving the assembly quality of the coupler terminal.

[0020] 5. In the present invention, the limit plate will also synchronously drive the limit block bar to descend, and the limit block bar will be squeezed by the passive inclined plate to slide in the direction of the corrected pin, compressing the spring three, which is conducive to clamping the corrected pin and preventing the pin from being offset when it is subsequently squeezed and assembled, thereby further improving the quality of the coupler terminal assembly.

[0021] 6. In the present invention, when the connecting strips on both sides slide on the adjustment frame in a direction approaching each other, the airbag will also be squeezed, and the gas in the airbag will be ejected through the magnetic nozzle plate, which is beneficial to remove the debris adhered to the pins and the assembly pressure plate, avoiding the adhered debris from affecting the normal extrusion assembly of the assembly pressure plate on the pins, thereby improving the assembly quality of the coupler terminal.

[0022] 7. In the present invention, when the front connecting strip in the process of descending is squeezed by the oblique strip and moves backward, it will also drive the magnetic strip to move backward synchronously. When the magnetic strip passes through the magnetic nozzle plate, it will generate a magnetic repulsive force on the magnetic nozzle plate, pushing the magnetic nozzle plate to slide to the left on the fixed frame, stretching spring four, and improving the spraying range of the magnetic nozzle plate, which is beneficial to ensure that no debris adheres to the pins and the assembly pressure plate, thereby improving the assembly quality of the coupler terminal and playing a good auxiliary effect.

[0023] To summarize, the limit plates on both sides can limit the front and rear sides of the pin, the passive correction plate can automatically correct the inward expansion of the pin, and the active correction plates on both sides can limit the left and right sides of the pin. Finally, the limit card strip can be used to fix the corrected pin, thereby ensuring that the pin remains completely vertical when being squeezed and assembled, and the surroundings of the pin are restricted, so that the pin will not bend when being squeezed and assembled, thereby ensuring the assembly quality of the coupler terminal.
