The holding arm 310 is provided with a folding arm 312 fixedly arranged at the other end of the folding sliding arm 313. The end platform shaft rod 302 is rotatably connected with the top platform 217 through a bearing, and the end platform shaft rod 302 is slidably connected in the sliding arm tube 219. The clamping block 218 is inserted in the sliding clamping groove 303. The perforated round table 315 is sleeved on the outside of the shaft arm platform 307 and moves back and forth outside the shaft arm platform 307. The convex head 304 is inserted in the spiral slide groove 306. The folding arm 312 is inserted in the folding arc groove 309. Through the counterclockwise rotation of the folding disk 308, a centering and aligning clamping structure for the speaker accessory 400 is formed between the three clamping arms 310. The two speaker accessories 400 are respectively placed in the discharge trough 204. Through the synchronous inward contraction of the three clamping arms 310, the centering and aligning clamping of the end of the speaker accessory 400 is realized, and one end of the speaker accessory 400 abuts against the outer surface of the abutting arm 311.

[0031] In summary, when performing alignment welding on the accessories of speakers or loudspeakers, specifically, when performing alignment welding on two speaker accessories 400, first place the two speaker accessories 400 back to back in the discharge trough 204 on the top of the welding feed rack assembly 200, then start the second cylinder 317 to retract, and drive the perforated circular table 315 to telescopically slide outside the shaft arm table 307 through the second cylinder 317. At this time, through the cooperation of the protrusion 304 and the spiral slide groove 306, the retracting disk 308 forms a counterclockwise rotating structure at the front end of the circular end disk 305. At this time, the retracting arm 312 is moved by the retracting arc groove 309, and the retracting sliding arm 313 slides linearly in the long arm 314 with the groove. At this time, a mutually retracted structure is formed between the three clamping arms 310. At this time, one end of the speaker accessory 400 is clamped and fixed by the three clamping arms 310. This center-aligned fixing method aligns the center of the speaker accessory 400 with the center of the retracting disk 308.

[0032] On the basis of the above, the first cylinder 211 is started at this time, and a square slide bar 215 is pushed forward by the first cylinder 211. At this time, the square slide bar 215 drives the gear arm 214 to move forward. At this time, through the gearing cooperation of the central gear 212 and the two gear arms 214, a structure of abutment and approach is formed between the two top platforms 217 on the two gear arms 214. The alignment arm assembly 300 of the present invention is rotatably set on the top platform 217, and the two speaker accessories 400 are clamped and fixed in the center on the two alignment arm assemblies 300. At this time, a structure to be welded that is centered and abutted is formed between the two speaker accessories 400.

[0033] On the basis of the above, when welding is performed, the toggle motor 105 drives the feed shaft 205 to rotate, and the feed shaft 205 drives the feed rack 201 to rotate. At this time, the arm tube gear 220 rotates outside the geared wheel 103, and through the engagement of the arm tube gear 220 on the geared wheel 103, the sliding arm tube 219 synchronously drives the end table shaft 302 to rotate through the cooperation of the block 218 and the sliding slot 303, that is, the rotation of the alignment arm assembly 300 is realized. In simple terms, when the speaker accessory 400 rotates with the feed rack 201 in the discharge trough 204, the speaker accessory 400 rotates through the self-rotation of the alignment arm assembly 300, that is, the speaker accessory 400 rotates itself. In this way, the laser welding head 203 can perform a circle of welding on the welding position of the two speaker accessories 400. The purpose of this rotation is to achieve a circle of welding between the two speaker accessories 400, through the ring movement of the speaker accessory 400 on the welding feeder rack assembly 200, that is, the speaker accessory 400 moves from the highest position to the lowest position of the welding feeder rack assembly 200. When it reaches the lowest position, the second cylinder 317 is started again. At this time, the second cylinder 317 extends forward, and the retracting plate 308 rotates clockwise, that is, the three clamping arms 310 form a clamping action to release the speaker accessory 400. At this time, the two speaker accessories 400 rotate along with the welding feeder rack assembly 200 to the lowest position of the welding feeder rack assembly 200. At this time, the two welded speaker accessories 400 can be directly dropped from the welding feeder rack assembly 200 onto the external conveyor belt, that is, the rapid unloading of the speaker or loudspeaker after welding.

[0034] On the basis of the above, the toggle motor 105 drives the toggle wheel 104 to rotate one circle. At this time, the toggle arm 106 toggles the feed wheel 206 180 degrees through the toggle slot 207. At this time, the feed shaft 205 rotates 180 degrees, that is, the two discharge slots 204 on the welding feed rack assembly 200 are interchanged from a high position to a low position. The high-position discharge slot 204 is for convenient placement of two speaker accessories 400, and the low-position discharge slot 204 is for convenient unloading after welding. At the same time, the present invention adopts the cooperation of the feed wheel 206 and the toggle wheel 104 to realize the 180-degree quantitative rotation of the welding feed rack assembly 200. In this way, it can be ensured that the two discharge slots 204 on the welding feed rack assembly 200 are in the replacement position of each other each time they rotate, with higher precision.

[0035] In another embodiment of the present invention, the folding disk 308 can be driven directly by a motor, replacing the second cylinder 317 in the present invention.

[0036] According to another embodiment of the present invention, when the three clamping arms 310 are retracted and closed to clamp and fix the speaker accessory 400, the outer side of one end of the speaker accessory 400 must abut against the outer end surface of the abutting arm 311, so as to ensure the concentricity of the clamping and fixing of the speaker accessory 400. In order to realize the present invention, an electromagnetic structure can be arranged inside the abutting arm 311. Through the electromagnetic structure, when power is turned on, the outer side of one end of the speaker accessory 400 placed inside the discharge trough 204 will be adsorbed on the outer side of the abutting arm 311, and the speaker accessory 400 is in the high-position discharge trough 204. When the speaker accessory 400 is in the low-position discharge trough 204, the electromagnetic structure inside the abutting arm 311 can be powered off, and the abutting arm 311 does not generate suction to the speaker accessory 400, so that when the three clamping arms 310 release the clamping of the speaker accessory 400, the two speaker accessories 400 can be unloaded after welding.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
