[0049] The implementation principle is as follows: First, by placing the housing and the pins at the housing conveying device 2 and the pin conveying device 4 respectively, the housing and the pins are automatically arranged and conveyed to the guide pipe 22 by the housing conveying device 2 and the pin conveying device 4; the rotating disk 11 drives the tooling seat 12 to move intermittently on the horizontal plane, so as to realize the corresponding processing / detection processes of multiple processing mechanisms on the housing or the finished product on the tooling seat 12;

[0050] Secondly, in the automatic housing feeding process, first, the housing distributor 35 distributes the housing in the guide pipe 22 of the housing conveying device 2, so that the distribution grooves 353 distribute the single housing in turn, and then the housing vertical driving part 33 in the housing automatic feeding mechanism 3 drives the housing feeding pneumatic clamp 34 to move towards the housing distribution seat 352, so that the housing feeding pneumatic clamp 34 picks up the housing in the distribution groove 353, and then under the interaction of the housing horizontal driving part 32 and the housing vertical driving part 33, the housing in the distribution groove 353 is automatically assembled onto the positioning mounting seat 122 in the tooling seat 12;

[0052] Next, in the automatic pin feeding and assembly process, first, the pin feeding and conveying device 4 guide pipe 22 of the pin feeding and conveying device 4 is converted from a horizontal state to a vertical state on the pin feeding seat 652 by the pin dividing and rotating member 65. Then, the pin feeding horizontal driving member 62 drives the pin feeding pneumatic gripper 64 to move towards the pin dividing and rotating member 65. The pin feeding pneumatic gripper 64 picks up the pins in a vertical state on the pin feeding seat 652. Then, under the interaction of the pin feeding vertical driving member 63 and the pin feeding horizontal driving member 62, the pins are automatically assembled from the guide pipe 22 of the pin feeding and conveying device 4 into the shell on the tooling seat 12. Then, the pin ejector rod 662 of the pin ejector member 66 is driven by the pin ejector cylinder 661 in the pin ejector member 66 to reciprocate towards the tooling seat 12 to complete the pin assembly process.

[0053] In the pin flattening process, the flattening cylinder group 82 in the pin flattening mechanism 8 drives the flattening rod 83 to move towards the tooling seat 12, and the surface of the flattening rod 83 gradually acts on the pins of the connector to complete the flattening process of multiple pins on the shell.

[0054] Finally, in the connector unloading process, the horizontal unloading cylinder group 92 and the vertical unloading cylinder group 93 in the connector unloading mechanism 9 move in the horizontal and vertical planes respectively, so that the unloading finger cylinder 94 automatically unloads the connector on the tooling seat 12 into the finished product receiving hopper 95 or the waste product receiving hopper 96. And through the electrical signal connection with the connector detection mechanism 7, the distinction between good and defective products of the connector is realized.

[0055] By sequentially arranging the shell automatic feeding mechanism 3, the shell alignment mechanism 5, the pin automatic feeding and assembly mechanism 6, the pin flattening mechanism 8, the connector detection mechanism 7, and the connector unloading mechanism 9 on the circumferential surface of the rotating disk 11, the automatic assembly, flattening, detection and other processes of the connector are realized, with an automatic pin insertion and assembly process, effectively reducing the operation intensity of the staff, improving the product production efficiency and product production quality.

[0056] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
