As the lifting cylinder descends, the empty carrier drops to a position that is compatible with the height of the claws of the handling module. Finally, the handling module is started to move the empty carrier to the first track on one side of the pin module.

The motor 407 drives the belt 406 to run through the transmission shaft 408, and the belt 406 drives the belt clip 410 to rise and fall, thereby driving the tray frame 404 to rise and fall.

[0060] In the specific production, the telescopic mechanism 405 adopts a cylinder, and a suction cup is provided at the end of the piston rod of the cylinder for adsorbing the receiving tray. The suction nozzle at the end of the mechanical arm of the unloading robot moves the finished connector to the receiving tray, and the cylinder is started to push the receiving tray carrying the finished connector into the silo; then the tray rack in the floor silo descends, and the empty receiving tray on the tray rack is sucked out with the help of the suction cup at the end of the cylinder to receive the next finished connector. Among them, walking wheels can also be installed at the bottom of the silo to facilitate the easy movement of the silo to any location.

[0061] Since the carrier 7 with the clip 02 before injection molding has been turned from a horizontal state to a vertical state by the turning module 600, and moved from the first track 21 to the second track 22 at the same time, the finished connector 00 after injection molding is collected in the bin 422 at the unloading station 4, and the empty carrier 7 is left on the second track 22. A turning module 700 is set at the end of the second track 22 to turn the vertically placed empty carrier 7 to a horizontal state, and move the horizontal empty carrier 7 to the first track 21 through the transport module 300 to perform the pin insertion operation of the next batch of connectors.

[0062] The specific application process of the present invention is as follows:

[0063] The clip before the pin 02 Fig.11As shown, the carrier 7 is installed in the carrier 7. Driven by the driving component on the first track 21, the carrier 7 passes through the pin module 100 one by one to complete the pin insertion operation of the flat pin 01. Then, the carrier 7 equipped with the clip 02 is moved from one first track 21 to another first track 21 through the end handling module 300, and then the pin insertion operation of the square pin 03 is completed through the pin module 2 200; then, the horizontal carrier 7 is turned to the vertical state through the flip module 600, and the visual image detector 11 is used to detect whether there is a missing or bent pin in the clip. The qualified products are clamped by the handling robot 6 to the injection molding machine 500 by the clip 02 in the carrier 7. After the injection molding, the finished connector 00 is clamped to the second track 22 by the handling robot 6; the appearance is first inspected by the 3D laser detector 12, and the finished connector 00 that meets the requirements is moved to the unloading station 4 via the second track 22, and the finished connector 00 is placed one by one in the bin 422 by the unloading module 400. The empty carrier 7 on the second track 22 is then moved to the first track 21 by the turning module 700 and the transport module 300 , and the next batch of connectors is produced by the pin module 100 .

[0064] In summary, the present invention has the advantages of reasonable design, compact structure, high degree of automation and high production efficiency. In the production process of the connector, the controller controls the actions of the pin module, the handling module, the flip module, the unloading module, the turning module and the handling robot to achieve automatic coordination of the production process. Fully automatic production greatly increases production volume and reduces production costs. The present invention is particularly suitable for mass production and can meet market demand.
