The utility model discloses a flexible disc of integrated starting gear ring structure relates to flexible disc technical field. The flexible disc of integrated starting gear ring structure, including flexible disc disc body, flexible disc outer end and starting tooth, is set up flexible disc waist hole on flexible disc disc body. The flexible disc of integrated starting gear ring structure, through the machining allowance of flexible disc outer end and remains starting tooth's processing forming, makes starting tooth and flexible disc outer end integrated moulding, cancels the welding of flexible disc outer end and starting gear ring in the prior art and becomes the design, avoids the size of welding scar and cannot standardization, and there is not one, reaches the assembly gear ring of reducing, prevents the occurrence of the incomplete welding, cancels the welding process flow, prevents the failure of welding scar crack, and reduces the cost of sub -parts, and the structure strength of flexible disc disc body is strengthened when the plate enhances the transmission torque, and the flexible disc waist hole symmetric distribution lightens disc body quality, and enough structural strength is reserved simultaneously.

The application discloses a production line and a production process for an automobile rear wall assembly, which comprises an inner plate assembly workbench, an outer plate assembly workbench, an inner-outer plate splicing workbench, a first repair welding workbench, a floor welding tongs, a stud welding tongs, an inspection bench, a first welding robot, a second welding robot and a grabbing robot, the first welding robot, the second welding robot and the grabbing robot are sequentially arranged, sequentially complete the welding assembly of the rear wall inner plate, the welding assembly of the rear wall outer plate, the welding splicing, spot welding repair welding and stud welding repair welding of the rear wall inner-outer plate assembly, and welding quality inspection is conducted on the processed rear wall assembly. The three robots cooperate with each other, improve the automation degree of the automobile rear wall assembly production, divide the welding work of a large number of welding points into three processes, reasonably distribute the working time length of each process, avoid the idle waiting of the robots and affect the overall production rhythm, improve the overall production efficiency of the production line, and avoid missed welding.

The present application relates to the technical field of battery string production, and particularly relates to a carrying and positioning assembly for battery piece and welding strip string welding and a battery piece string welding method. The carrying and positioning assembly comprises a feeding suction plate, a transfer seat, a blanking suction plate, a welding base and a plurality of elastic pressing mechanisms. The bottom of the feeding suction plate is provided with a first suction plane, and the two ends of the feeding suction plate are provided with cutting heads. The cutting heads are provided with first positioning protrusions matched with positioning holes. The transfer seat is provided with a first supporting plane and a cutting groove for the cutting heads to extend into. The bottom of the blanking suction plate is provided with a second suction plane, and the blanking suction plate is provided with a plurality of light transmission holes corresponding to the welding areas of the welding strips and allowing the welding laser to pass through. The welding base is provided with a second supporting plane for the conveying mechanism of the battery pieces to pass through. The plurality of elastic pressing mechanisms are telescopically arranged on the welding base, and the positions of the elastic pressing mechanisms correspond to the welding areas. The present application can improve the quality of battery piece string welding and avoid incomplete welding and false welding.
