The detection is performed to prevent the occurrence of a missing stud on the top post of the positioning jig 53.

The fourth step: the five inner concave pieces are grabbed from the marking jig by the automatic inner concave piece module 4 and assembled to the positioning jig 53 provided with the stud. After the inner concave piece 102 is assembled to the positioning jig 53, the ejector pin 566 drives the ejector top plate 558 to move vertically upwards, so that the top post 560 drives the stud 104 to move upward due to the inner concave piece 102 is fixed by the fixing of the suction cup 556 and the second positioning pin 562, so that the inner concave piece 102 and the annular protrusion of the stud 104 are engaged.

Step 5: continue to rotate the rotating machine table 5 to the welding station, and use the assembly mechanism 11 to clamp the positioning fixture 53 from the rotating machine table 5, and clamp the bottom surface and the top surface of the positioning fixture 53 by using the assembly mechanism. The side surface is used to ensure the tight bonding of the inner concave piece 102 and the stud 104, and then the inner concave piece 102 and the stud 104 on the positioning jig 53 are used by the welding module 6. Welding is performed.

Step 6: Continue to rotate the rotary table 5 to the lower clinker station, and remove the welded inner concave piece 102 by the automatic lower inner die module 7 and place it on the empty tray 210.

The seventh step: continuing to rotate the rotating machine 5 to the second detecting station, and detecting by using the second automatic detecting device 9 set by the second detecting station position to prevent the stud 104 from remaining on the top post 560 Happening. Thus, the assembly and welding of the inner concave piece 102 and the stud 104 are completed.

In summary, the self-concave automatic assembly welding machine 100 provided by the utility model has an inner concave piece loading module 2, an automatic upper stud module 1, a marking fixture 3, and an automatic inner concave piece. The module 4, the rotating machine 5, the welding module 6, the automatic lower concave module 7, the first automatic detecting device 8, and the second automatic detecting device 9 are all assembled and arranged in the carrying platform 101, thereby realizing The loading of the inner concave piece, the assembly of the inner concave piece and the stud, the inspection before welding, the welding, the detection after the welding and the fully automated operation of the blanking save labor, save the site and increase the production capacity.
