That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, which is also called a connector. Connectors are widely used in electronic devices to achieve electrical connections between internal electrical components.

[0080] Furthermore, a plurality of fences 90 are included, and the plurality of fences 90 are cooperatively constructed to surround the outer sides of the two transport devices 80 .

[0081] The working process of this embodiment is described in detail as follows:

[0082] First, the shell feeding device 10 and the chip feeding device 20 respectively feed the shell and the chip to the board-mounted welding device 30, the shell feeding mechanism 32 and the chip feeding mechanism 33 respectively feed the shell and the chip to the assembly station 34, the positioning part 361 of the positioning mechanism 36 positions the chip, and the push rod 351 of the assembly mechanism 35 pushes the shell out, so that the chip and the shell are assembled, then, the assembled chip and the shell enter the welding track 37 and move to the welding station 371, and the laser welding head 391 lasers the chip and the shell After welding and fixing, the rotating part 381 rotates the assembled chip and the shell 180°, and the laser welding head 391 welds again, so that the chip and the shell are fixed by double-sided laser welding. Then, the semi-finished product enters the semi-finished product loading device 40, and the clamping arm 446 places the chip and the shell fixed by double-sided laser welding in the carrier 401. One of the transport devices 80 places the carrier 401 in the first molding cavity 5211 for the first injection molding. The first injection molding uses a softer plastic. The softer plastic has Elasticity, which can provide excellent buffering effect for the connector. When impacted, it can effectively offset the impact force and protect the chip more effectively. After the first injection molding is completed, another handling device 80 takes the carrier 401 out of the first molding cavity 5211 and places it in the second molding cavity 6211 for a second injection molding to obtain the final required workpiece. The second injection molding uses a harder plastic material to effectively protect the inner layer of the softer plastic from being scratched. The design of the composite use of the softer inner mold and the harder outer mold can maximize the protection of the chip, thereby extending the service life of the connector. Finally, another handling device 80 transports the carrier 401 to the test station 72, and the first suction cup group 738 absorbs and transports the workpiece to the detection slot 741 of the detection station 74. The first detection interface 751 and the second detection interface 761 are simultaneously connected to the workpiece for detection. After the detection, the second suction cup group 739 absorbs and moves the workpiece away from the detection slot 741. The workpiece that passes the detection is placed in the discharge track 77 for discharge, and the workpiece that fails the detection is placed in the defective product storage box 78.

[0083] The design focus of the present invention is: by arranging multiple first glue flow holes at intervals on the bottom surface of the first strip groove and connecting with the first molding cavity, and arranging multiple second glue flow holes at intervals on the bottom surface of the second strip groove and connecting with the second molding cavity, during the connector production process, multiple products can be injected simultaneously each time, and the axis of each first glue flow channel is parallel to the first strip groove, the inner diameter of each first glue flow channel gradually decreases from the inside to the outside, and the axis of each second glue flow channel is parallel to the second strip groove, and the inner diameter of each second glue flow channel gradually decreases from the inside to the outside, ensuring that when the glue flows out of the first glue flow channel or the second glue flow channel, the output ends of the two are completely filled with glue, so that the glue flows to the corresponding workpiece at the same time and evenly, thereby reducing the defective rate.

[0084] 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.
