[0001] The invention relates to the field of wire material processing equipment, in particular to a conveying structure of an automatic end-punching and shell-inserting machine. Background Art

[0002] Existing electronic products all involve connecting wires between electronic components and circuit boards. The connecting wires can be directly plugged in and used, which is very convenient to use. The connecting wires include connecting wires, sheathed wires, electronic wires, etc., and their structures usually include wires and plastic shells. One end of the wire has solder and the other end has a terminal. The terminal is inserted into the plastic shell to form a connecting wire.

[0003] Traditional technologies mostly use manual methods to process connecting wires, resulting in low production efficiency and inability to ensure the quality of connecting wires. In order to improve production efficiency and connecting wire quality, equipment for processing connecting wires has appeared one after another. Since connecting wires need to go through multiple processes such as wire stripping, wire cutting, end beating, and rubber shell insertion, wire stripping, end beating, and shell insertion machines have well realized multi-process processing, but they usually require robots to move between various workstations, require multiple high-precision robots, and are costly. There are also some shell insertion machines with conveyor belts, but their conveyor belts cannot achieve intermittent transmission for individual processing of workstations, and still need to be used in conjunction with robots.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Summary of the invention

At the same time, the conveying unit 432 inputs the plug-in shell 100 into the input port 4333 of the insertion robot 4331, and then the insertion robot 4331 moves toward the side of the plug-in shell. At this time, part of the plug-in shell 100 is exposed outside the insertion port 4332 and the input port 4333, and then the limiting unit 4341 of the limiting device 434 moves downward to limit the plug-in shell 100 exposed at the insertion port 4332. 32, and then the pushing unit 4351 pushes the entire plastic shell 100 completely into the positioning cavity, and then the limiting unit 4341 returns to the initial position upward, and the insertion manipulator 4331 moves toward the core wire and inserts the plastic shell 100 into the head of the terminal (i.e., the first depth), which is pre-insertion, and then the terminal fixing mechanism 42 releases the terminal, and the insertion manipulator 4331 continues to insert the plastic shell 100 toward the core wire to the second depth to complete the plug-in shell, and then the second wire fixing mechanism 41 releases the wire, and the disengagement mechanism 53 located at the third station moves downward to send the jig 52 carrying the wire after the plug-in shell is completed back to the conveyor belt 51;

[0103] Finally, the wire is transported to the material taking station by the conveyor belt 51 and taken down by the material taking mechanism 90, and then the empty fixture 52 is returned to the loading side through the material returning device 70, thus completing the whole processing.

[0104] To sum up, the design focus of the present invention is that it is mainly through setting a disengagement mechanism on the conveying device, and setting a disengagement mechanism corresponding to each workstation, so that the disengagement mechanism can disengage the jig conveyed to different workstations for processing at the corresponding workstation or bring the jig processed at the corresponding workstation back to the conveyor belt, thereby realizing the intermittent matching of the jigs to different workstations, making the processing of different workstations independent, avoiding mutual influence between different workstations, and ensuring normal operation.

[0105] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
