[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides Figure 1-12The connector assembly equipment for producing a junction box shown in the figure includes a machine table 100 and a terminal riveting machine 200, a tinning mechanism 300, a connector mounting mechanism 400 and a connector nut mounting mechanism 500, which are arranged in sequence and spaced apart at the top of the machine table 100 and located on one side of a wire translation conveyor line 900, and a wire mechanical claw mechanism located above the wire translation conveyor line 900 and at a position corresponding to the connector mounting mechanism 400 and the connector nut mounting mechanism 500. A detachable protective cover 101 is installed on the top of the machine table 100, and a plurality of transparent observation windows are arranged on the protective cover 101. A wire translation conveyor line 900 is arranged on the top of the machine table 100. The wire translation conveyor line 900 is used to drive the wire to move horizontally.

[0039] Next, the connector nut installation mechanism 500 is used to tighten the nut on the outer wall of the connector, and the wire mechanical claw mechanism is used to grab the wire.

[0040] In the above embodiment, the wire with the connector plugged in continues to be sent to the front of the connector nut installation mechanism 500 by the wire translation conveyor line 900, and the nut feeding clamp 800 inserts the connector part of the wire into the fixed sleeve. The nut of the connector is pushed to move the connecting seat 504 by the nut clamping cylinder 503, driving the three-petal clamp 505 to clamp the nut, and then the three-petal clamp 505 is driven by the clamp rotation drive assembly 502 to rotate to achieve the screwing of the nut. As the nut rotates, the fixed sleeve will move forward with the connector. The sleeve position detection photoelectric 508 can control whether the nut is tightened in place. After the nut is tightened in place on the outer wall of the connector, it means that the connector is assembled on the wire. Finally, the unloading clamp 600 grabs the finished wire and unloads it to the unloading area.
