Fig. 9a and 9b are schematic structural views illustrating the automatic welding mechanism in the initial state in the present embodiment, and it can be seen from fig. 9a that: in an initial state, the limit switch induction sheet 2131 is located at a corresponding position of the initial/receiving position limit switch 2142, the left and right springs 21145 are in a compressed pre-tightening state under the action of the elastic pre-tightening mechanism 2115, the ceramic ring clamp 2114 is wholly in a lifting state, and only a distance H (usually 10-20 mm, if the elastic pre-tightening mechanism 2115 is not provided, at least 200mm is needed) matched with the height of the ceramic ring is reserved between the bottom end face of the stud chuck 2113 and the bottom end face of the ceramic ring chuck 21141, so that the height of the left and right guide posts 21143 can be shortened by at least 180mm, the height of the upper stroke and the height of the lower stroke of the welding gun main body 211 can be obviously shortened, the manufacturing cost of the vertical lifting mechanism 214 can be obviously reduced, the occupied volume is obviously reduced, the round trip time of single welding can be shortened, and the welding efficiency is obviously improved); as can be seen again in fig. 9 b: in the initial state, the receiving clamp 241 is located right below the porcelain ring clamp 21141, the spring 236 is in the extended initial state, the rectangular movable plate 232 is pushed by the spring 236 to the material clamp 22 and is limited under the blocking of the L-shaped limiting baffle 238 and the limiting column 239, so that the material blocking rod 230 penetrates through the groove 223 and is blocked in the discharge hole of the material clamp 22, and the material clamp 22 is in the state to be discharged.

When the receiving and conveying motor 242 drives the receiving and conveying clamp 241 to rotate towards the material clamp 22, as the receiving and conveying clamp 241 approaches the discharging end of the material clamp, the roller 234 at the lower part of the receiving and conveying clamp 241 is in rolling contact with the inclined plane 2332 of the right-angled triangular push plate, and as the roller 234 rolls on the inclined plane 2332 from low to high, the roller 234 generates an outward thrust action on the inclined plane 2332 as the roller 234 rolls towards the high end of the inclined plane 2332, and as the right-angled triangular push plate 233 is fixedly connected with the rectangular movable plate 232, the inclined plane 2332 receives the outward thrust of the roller 234 and then drives the rectangular movable plate 232 to move outward, and as the striker rod 230 is fixedly arranged on the rectangular movable plate 232, the striker rod 230 also moves outward as the rectangular movable plate 232 moves outward; when the receiving clamp 241 rotates until the opening of the U-shaped receiving groove 2411 is just butted with the discharge hole of the material clamp 22 (the material level sensor 243 can be sensed by the receiving motor 242 to limit), the roller 234 rolls to the highest end of the inclined plane 2332, the rectangular movable plate 232 is subjected to the maximum outward pushing force, so that the L-shaped limiting baffle 238 is separated from the limiting column 239, the spring 236 is compressed, and the head of the striker rod 230 retreats into the groove 223; since the material clamp 22 is installed with a certain inclination, the T-shaped pin 9 with the porcelain ring 8 on the material clamp 22 will smoothly fall into the U-shaped receiving groove 2411 (see fig. 9b and 10 b) along with the retraction of the head of the striker rod 230, and the automatic welding gun 21 at this time remains in the initial state (see fig. 10 a).

When the receiving and conveying motor 242 drives the received receiving and conveying clamp 241 to rotate towards the welding gun material taking position, the roller 234 rolls from the highest end to the lower end of the inclined plane 2332 until the roller is separated from the inclined plane 2332, so that the outward thrust generated by the roller 234 on the inclined plane 2332 is gradually reduced until the outward thrust disappears, and the rectangular movable plate 232 is pushed to the side of the material clamp 22 under the resilience of the spring 236 until the outward thrust is limited under the matched blocking of the L-shaped limiting baffle 238 and the limiting column 239, so that the material blocking rod 230 passes through the groove 223 and is blocked in the material outlet of the material clamp 22 (because the diameter of the head of the T-shaped bolt 9 is larger than that of the column body, a gap through which the material blocking rod 230 passes is formed between the column bodies of the T-shaped bolt 9), and the material clamp 22 is in the material taking state again; when the pick-up clamp 241 rotates to a position directly below the porcelain ring clamp 21141, the pick-up motor 242 may stop rotating by sensing the position of the gun pick-up position sensor 244 (see fig. 11 b); at this time, the vertical lifting mechanism 214 drives the lifting slider 213 to move downwards, and since the welding gun body fixing plate 212 is fixedly connected with the lifting slider 213 and the welding gun body 211 is fixedly connected with the welding gun body fixing plate 212, the welding gun body 211 moves downwards along with the downward movement of the lifting slider 213 until the limit switch induction sheet 2131 is located at a position corresponding to the welding gun material taking position limit switch 2143, and at this time, the porcelain ring chuck 21141 already clamps the porcelain ring 8; in addition, although the mounting height of the fixed pulley 21152 is no longer kept to make the flexible tension member 21151 in a tension and tensed state due to the descending of the welding gun body fixing plate 212, the porcelain ring clamp 21141 is in a limit and interference effect of the receiving clamp 241, so that the left and right springs 21145 are still in a compression and pretension state (see fig. 11 a); then, a main shaft driving mechanism (not shown in the figures, but known in the art) of the welding gun main body 211 drives a main shaft body 2112 to descend to drive a stud chuck 2113 to descend to clamp the head of the T-shaped stud 9, so as to complete the material taking of the automatic welding gun 21, and then, a vertical lifting mechanism 214 drives a lifting slider 213 to ascend until a limit switch induction sheet 2131 is located at a corresponding position of an initial/receiving position limit switch 2142, a ceramic ring chuck 21141 is separated from a receiving clamp 241 (at this time, a left spring 21145 and a right spring 21145 are still in a compressed pre-tightening state under the action of an elastic pre-tightening mechanism 2115), at this time, the receiving clamp 241 is driven by a receiving motor 242 to retreat to the other side of the welding gun main body 211, when the retreat is in place, the receiving motor 242 stops rotating under the induction of a retreat sensor 245 (see fig. 12 b), the vertical lifting mechanism 214 drives the lifting slider 213 to descend, so that the installation height of the fixed pulley 21152 is lowered with the descending of the welding gun body fixing plate 212, and the flexible tension member 21151 is in a released state, and the left and right springs 21145 are in a rebounded state, so that the left and right guide posts 21143 descend until the bottom end surface of the porcelain ring 8 is flush with the bottom end surface of the T-shaped stud 9 and is in a state of being clamped to be welded (see fig. 12 a).

Under the continuous driving of the vertical lifting mechanism 214, the welding gun main body 211 in the state of being clamped to be welded continues to descend until reaching the lower limit position, namely: the limit switch induction sheet 2131 is located at a corresponding position of the lower limit switch 2144, the bottom end surface of the porcelain ring 8 contacts the surface of the embedded part 7 to be welded, and at this time, the fixed plate 212 of the welding gun body descends to the lowest position, so that the installation height of the fixed pulley 21152 has no stretching effect on the flexible stretching piece 21151 (see fig. 13); then, the welding gun body 211 starts welding, and when the welding is finished, the welding gun body 211 can quickly move upwards to return to the initial state under the driving of the vertical lifting mechanism 214, and the receiving clamp 241 returns to the position right below the porcelain ring clamp 21141 under the driving of the receiving motor 242, so that one welding operation is finished.

The T-shaped bolt 9 with the porcelain ring 8 in the material clamp 22 can be manually placed or placed by adopting a device for realizing the automatic feeding of the T-shaped bolt described in the utility model patent ZL 201620260551.6.

In addition, in this embodiment, since the stoppers 2412 are fixedly disposed at two ends of the opening of the U-shaped material receiving groove 2411 of the receiving and sending clamp 241, and the stoppers 2412 protrude from the top surface of the U-shaped material receiving groove 2411, the ceramic ring 8 on the top surface of the U-shaped material receiving groove 2411 can be blocked by the stoppers 2412, so as to ensure that the ceramic ring 8 on the U-shaped material receiving groove 2411 and the T-shaped stud 9 sleeved in the ceramic ring 8 do not slide down when the receiving and sending clamp 241 rotates to the welding gun material taking position (see fig. 11 b).

And because the rear side part of the vertical lifting mechanism 214 is in sliding connection with the X-direction slide rail 121, the whole automatic welding mechanism 2 can perform left-right and front-back displacement motion on the double-shaft motion bracket 12, so as to better meet the welding requirement of welding multiple rows and multiple columns of T-shaped studs 9 with ceramic rings 8 on one embedded part 7 to be welded.
