[0050] Working steps Step 1, loading process: the conveyor belt a201 conveys the sheet metal part (composed of the sleeve 800 and the connecting plate 801), and the manipulator 202 moves the sheet metal part on the conveyor belt a201 to the positioning rod 105, specifically, the sleeve 800 is sleeved on the outside of the positioning rod 105; the positioning rod 105 adsorbs and fixes the sheet metal part; the rotating driving part c102 drives the rotating disk 103 to rotate, and transfers the sheet metal part sleeved on the positioning rod 105 to the oiling station; Step 2, oiling process: the rotary drive member a302 drives the flip plate a303 to flip, the linear drive member a304 drives the support wheel 306 to move upward, and drives the support wheel 306 to support the sheet metal part sleeved on the positioning rod 105, the rotary drive member b307 drives the flip plate b308 to flip, and the linear drive member b309 drives the oiling wheel 300 to oil the surface of the sheet metal part, and applying lubricating oil is beneficial to the stamping effect; Step 3, stamping process: the rotary drive c102 drives the rotating disk 103 to rotate, and transfers the sheet metal part sleeved on the positioning rod 105 to the stamping station. At this time, the sheet metal part is tilted and placed on the lower mold 312. The linear drive c108 drives the conical pressure plate 110 to move downward and press on the fixing seat 104. The elastic connecting member 107 is compressed. At this time, the sheet metal part is in a horizontal state on the lower mold 312. The linear drive e313 drives the upper mold 314 to stamp the horizontal sheet metal part, and punches out the installation hole in the connecting plate 801. Step 4, grinding process: the rotary drive member c102 drives the rotating disk 103 to rotate, transfers the sheet metal part sleeved on the positioning rod 105 to the welding station, drives the lifting seat 431 to move upward until the sheet metal part is horizontally located above the lifting seat 431, the rotary drive member d415 drives the rotating frame 416 to rotate, drives the grinding assembly 42 to rotate downward, and the rotary drive member e421 drives the flexible grinding block 422 to rotate. The rotating flexible grinding block 422 grinds the mounting hole of the sheet metal part to increase the roughness of the welding area; Step 5, assembly process: the conveyor belt b411 transmits the connecting sleeve 802, the rotating driving member d415 drives the rotating frame 416 to rotate, drives the adsorption sleeve 418 to rotate downward, and drives the adsorption sleeve 418 to carry and press the connecting sleeve 802 on the conveyor belt b411 into the installation hole of the sheet metal part for subsequent welding; Step 6, coating process: the linear drive member d432 drives the coating assembly 43, the welding assembly 44, the support block 435, and the swing rod 436 to extend upward along the mounting hole and the connecting sleeve 802, drives the swing rod 436 to rotate to a horizontal state, drives the swing arm b441 to swing upward, and drives the swing arm a437 to rotate downward to an inclined state, at which time the coating block 438 contacts the connecting sleeve 802 and the welding area of ​​the sheet metal; The rotating driving member f433 drives the coating block 438 to rotate along the axis of the connecting sleeve 802, and the coating block 438 applies the anti-transmitting agent in a ring shape on the welding area of ​​the connecting sleeve 802 and the sheet metal part, thereby increasing the roughness of the welding area to facilitate the absorption of the anti-transmitting agent.

[0051] Step 7, welding process: drive the swing arm a437 to swing upward, drive the swing arm b441 to rotate downward to a tilted state, at this time, the welding nozzle 442 contacts the connecting sleeve 802 and the welding area of ​​the sheet metal (such as Fig.18 As shown in the D state in FIG), the welding nozzle 442 is driven to rotate along the axis of the connecting sleeve 802, and the welding nozzle 442 performs annular welding on the welding area of ​​the connecting sleeve 802 and the sheet metal part, and the permeability enhancer enhances the welding effect.

[0052] Step eight, adsorption and unloading process: the rotating driving member c102 drives the rotating disk 103 to rotate, and transfers the sheet metal parts sleeved on the positioning rod 105 to different stations. When it is in the loading station, oiling station, stamping station, and welding station, the vent pipe 115 is connected to the negative pressure groove 1121, that is, the negative pressure is transmitted to the adsorption hole 1051 through the vent pipe 115 and the pressure chamber 1041 to adsorb and fix the sheet metal parts on the positioning rod 105 to prevent the sheet metal parts from detaching. When the sheet metal parts are transferred to the unloading station, the positive pressure hole 1122 is connected to the vent pipe 115, and the positive pressure is transmitted to the adsorption hole 1051 through the vent pipe 115 and the pressure chamber 1041 to blow the sheet metal parts down until the sheet metal parts fall into the collection box, thereby completing the unloading of the sheet metal parts.
