Therefore, when performing wire insertion assembly, the corresponding type of plastic terminal is moved to the corresponding position of the wire insertion auxiliary mechanism 9 for wire insertion assembly. In other embodiments, the wire insertion auxiliary mechanism 9 and the wire separation auxiliary mechanism 10 can be in the form of a fixed single station.

[0068] In other embodiments, the plug-in wire introduction auxiliary mechanism 9 may include a rotary drive member, a rotating disk driven by the rotary drive member to rotate, a plurality of lifting cylinders arranged in an annular manner on the rotating disk, and a plug-in wire guide plate 94 driven by the lifting cylinder to move up and down, and each plug-in wire guide plate 94 is provided with a plug-in introduction groove 95 that is shaped like the corresponding plastic terminal plug-in port at the end thereof, and then a group of wire separation auxiliary mechanisms 10 are provided below the rotating disk.

[0069] The wire spacing auxiliary mechanism 10 includes an eleventh cylinder 101 and a wire blocking rod 102 driven by the eleventh cylinder 101 to move up and down.

[0070] When the positioning carrier 3 carries the plastic terminal and moves to the corresponding wire plug-in assembly position, the wire plug-in guide plate 94 in the corresponding wire plug-in introduction auxiliary mechanism 9 sticks to the plastic terminal wire plug-in port to provide guidance for the insertion of the wire; since there are multiple wires that need to be inserted into a plastic terminal, after the wires are inserted into the plastic terminal, in order to prevent the already inserted wires from interfering with the wires to be inserted later, the wire blocking rod 102 in the wire spacing auxiliary mechanism 10 can effectively block the already inserted wires aside to ensure the smooth insertion of the subsequent wires.

[0071] The working principle of the connector automatic assembly device 100 that realizes flexible combination of multiple types of plastic terminals and wires in this embodiment is as follows:

[0072] 1) The feeding mechanism 1 delivers different types of plastic terminals to the end of the feeding channel 13, and then the first conveying mechanism 4 grabs them into the positioning carrier 3 on the fixture positioning plate 2;

[0073] 2) The second transport mechanism 6 grabs the positioning carrier 3 from the fixture positioning plate 2 to the carrier positioning mechanism 5, and fixes the position through the end positioning device 53 and the second positioning column 52, and fixes the plastic terminal in the positioning carrier 3 through the clamping drive device 54;

[0074] 3) The wire plug assembly transfer mechanism 20 drives the carrier positioning mechanism 5 to move to the corresponding wire plug assembly position;

[0075] 4) The positioning carrier 3 moves to the position of the plug-in wire introduction auxiliary mechanism 9 corresponding to the plastic terminal, and the corresponding plug-in wire guide plate 94 sticks to the plug-in wire port of the plastic terminal;

[0076] 5) The wire clamping and inserting unit 83 clamps the required wire from the wire clamp fixture 77, moves to the wire plugging and assembly position, and inserts it into the plastic terminal through the wire plugging unit 837. Then, the already inserted wire is blocked aside by the wire spacing auxiliary mechanism 10, and the wire clamping and inserting unit 83 clamps the required wire again for wire plugging and assembly;

[0077] 6) When all the wires required for the plastic terminal are inserted and assembled, the wire clamp insertion unit 83 takes the assembled connector out of the positioning carrier 3, moves it to the wire clamp fixture 77, and loads and outputs it through the wire clamp fixture 77; repeating the above steps, all types of connectors required in the same large product can be assembled according to product requirements, and plastic terminals and wires can be flexibly equipped according to the model of each connector. Different types of wires and different quantities of wires can be equipped according to requirements, thereby greatly improving the types and efficiency of connector assembly.

[0078] In this embodiment, the feeding unit can be flexibly set according to the types of plastic terminals included in a product, and all wires required for the product can be placed on the wire clamp at the same time; during assembly, according to design requirements, one plastic terminal can be flexibly assembled and inserted into multiple wires of different models or the same model, so that a diversified connector formed by a combination of different plastic terminals and different wires can be flexibly realized.

[0079] This embodiment realizes the connector automatic assembly equipment with flexible combination of multiple types of plastic terminals and wires, and realizes the purpose of automatic assembly of different wires and different connectors. By setting different connector feeding groups, wire clamps with wires of different specifications are installed, and then the connector is transported to the insertion mechanism by the transport mechanism, and then the insertion mechanism inserts different types of wires with terminals into the connector to complete the assembly. It not only greatly improves production efficiency and reduces enterprise costs, but also has strong versatility.

[0080] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
