Abstract
The invention relates to an automobile rear floor welding technology. The automobile rear floor welding technology includes the following steps that (a) a cantilever is hung on a front material rack,a rear floor sub-assembly workpiece and a rear floor frame assembly workpiece are grabbed to be sequentially stacked onto the front end of an assembly tool, and the assembly tool is started after placing is completed; (b) a welding robot R1 and a welding robot R2 drive C-shaped soldering pliers to conduct uniform spot welding on the periphery of a stacked workpiece formed by the rear floor sub-assembly workpiece and the rear floor frame assembly workpiece after receiving starting information, the welding robot R1 and the welding robot R2 conduct spot welding for 24 points to form a semi-finished product assembly, and a first signal is sent out after the working is completed; (c) a welding robot R3 drives a lifting handle to grab the semi-finished product assembly after receiving a first signal, spot welding lasts for 34 points on fixed soldering pliers, then the product is put onto a repair welding tool, and a second signal is sent out after the product is put in place; and (d) a welding robot R4, a welding robot R5, a welding robot R6 and a welding robot R7 on the repair welding tool drive X-shaped soldering pliers to conduct spot welding on the semi-finished product assembly after receiving second information.
