When the bottom clip feeding device 6 works, bottom clips are sequentially fed from the material distributing seat 66, after the bottom clips reach the end part, the material distributing push rod 672 pushes the side air cylinder 671 to move, the bottom clips at the end part are moved out to reach the rotating sleeve 68, then the lifting air cylinder 611 drives the positioning ejector pins 69 to lift, so that the positioning ejector pins 69 are positioned in holes of the bottom clips, then the rotating air cylinder 610 rotates to enable the bottom clips to rotate ninety degrees, then the finger air cylinders 65 clamp the bottom clips, the bottom clips are moved to a jig under the action of the horizontal air cylinder 62 and the vertical air cylinder 64, and the third side air cylinder 601 and the fourth side air cylinder 602 are used for driving a positioning component in the jig to position the bottom clips.

The bottom clamping piece feeding device 6 solves the problems that the efficiency is low in the bottom clamping piece assembling process, clamping is difficult, and clamping precision is low, and for the problem that continuous feeding is difficult to clamp, a single bottom clamping piece is separated towards the side by arranging the material distributing assembly 67, sufficient space is generated for clamping, the separated bottom clamping piece is rotated, the clamping direction is changed, and the bottom clamping piece is prevented from being deformed and bent in the clamping process; the bottom clamping piece is positioned by the material distributing push rod 672 in the separation moving process and is positioned by the positioning ejector pin 69 in the rotating process, so that the position of a workpiece is kept, and the assembly precision of the clamping precision is improved; the third side pushing cylinder 601 and the fourth side pushing cylinder 602 are arranged, so that the two sides of the bottom clamping piece after the feeding can be positioned and corrected again.

As shown in fig. 8, the side clip loading device 5 has a similar principle to the bottom clip loading device 6, and includes a carrying mechanism 51, a separating mechanism 52 and a rotating mechanism 53, wherein the separating mechanism 52 pushes a single side clip to the rotating mechanism 53, the rotating mechanism positions and rotates the side clip, and then the carrying mechanism 51 clamps and carries the side clip to the jig.

The automatic production equipment for the wire connector is processed sequentially through the following steps when in work:

conducting wire joint feeding: the material distributing cylinder 35 drives the material distributing block 34 to lift up, so that the wire connectors in the material passing table 32 are lifted up to be separated, and then the clamping and conveying manipulator 31 works to clamp the wire connectors and convey the wire connectors into a jig;

(II) positioning sheet feeding: the positioning pieces sequentially pass through the material table 46, the jacking cylinder 49 drives the jacking block 48 to move upwards to lift up a single positioning piece, then the suction assembly 45 realizes two-dimensional movement under the combined action of the transverse moving cylinder 42 and the longitudinal moving cylinder 44, the positioning block 453 descends and is inserted into the jacking block 48 to realize positioning, the suction head 452 descends to start sucking air after contacting with the positioning piece, the positioning piece is sucked and moved into a jig and sleeved on a lead connector, and then the first side pushing cylinder 410 and the second side pushing cylinder 412 work to drive the jig and center and position the placed positioning piece;

(III) feeding side clamping pieces: the separating mechanism 52 pushes the single side clamping piece to the rotating mechanism 53, the rotating mechanism positions and rotates the side clamping piece, and then the carrying mechanism 51 clamps and carries the side clamping piece into the jig;

(IV) feeding the bottom clamping piece: the bottom clamping pieces are sequentially fed from the material distribution seat 66, after the bottom clamping pieces reach the end parts, the material distribution push rod 672 pushes the side air cylinders 671 to move, the bottom clamping pieces at the end parts are moved out to reach the rotating sleeve 68, then the lifting air cylinder 611 drives the positioning ejector pins 69 to lift, the positioning ejector pins 69 are positioned in holes of the bottom clamping pieces, then the rotating air cylinder 610 rotates to enable the bottom clamping pieces to rotate ninety degrees, then the finger air cylinders 65 clamp the bottom clamping pieces, the bottom clamping pieces are moved to be conveyed to the jig under the action of the horizontal air cylinders 62 and the vertical air cylinders 64, and the third side air cylinder 601 and the fourth side air cylinder 602 are used for driving positioning parts in the jig to position;

(V) assembly detection: the detection device detects the heights of the positioning sheet, the side clamping sheet and the bottom clamping sheet sleeved on the lead joint by a contact type height measurement method, and whether the correct falling position exists or not;

(VI) punching and riveting: punching and riveting the workpiece qualified in the last step through a punching device 7, so that the positioning sheet, the side clamping sheet and the bottom clamping sheet are all fixed on the lead joint;

(VII) blanking and carrying: and the blanking device carries out blanking and carrying on the products which are assembled and riveted.
