8. A welding method for an automatic welding device of thin sheets is characterized by comprising the following steps:

s1: when the sheets need to be welded, the operating system starts to work, the moving operating system drives the first feeding tray and the second feeding tray to start to work, and the moving first feeding tray can convey the sheets to a designated area;

s2: when the thin sheet is positioned in the designated area, the driving part starts to work, the moving driving part drives the sliding block at the output end of the driving part to start to work, the moving sliding block can start to move on the feeding slide rail under the driving of the driving part and the matching of the sliding block, the position of the moving sliding block on the feeding slide rail can be adjusted, the moving sliding block can push the thin sheet positioned at the expected position to start to move, and the moving thin sheet is pushed to the conveying equipment, so that the conveying work of the device is finished;

s3: after the sliding block finishes the transportation work, the driving part starts to work at the moment, the moving driving part drives the sliding block to start to move in the opposite direction when the sheet is pushed, the working sliding block is in contact with the damping equipment to finish the feeding work, and the sliding block is located at the initial position to prepare for the next feeding work;

s4: when the thin sheet is positioned on the transportation device, the transportation device starts to work at the moment, the moving transportation device drives the thin sheet to start to move, the moving thin sheet is conveyed to a specified position, the transportation motor starts to work in the transportation process, the moving transportation motor drives the cam disc to start to work, the moving cam disc drives the driving wheel to start to work, the cam disc is driven by the transportation motor to start to do circular motion, the moving cam disc drives the driving wheel to start to do circular motion, the moving driving wheel applies a force which is vertical to a circle center connecting line to the connecting block, and after the force is decomposed, a horizontal force is applied to the connecting frame at the moment, so that the connecting frame can be driven to move in the horizontal direction, and meanwhile, a force in the vertical direction is generated to drive the moving rod to move downwards, the moving rod can move to the output end of the second feeding disc, the grabbing arm on the moving rod can grab another product, the conveying motor works in the reverse direction, the moving conveying motor drives the product to be conveyed to the position above the thin sheet on the conveying device, and the grabbing arm can place the product on the thin sheet to finish the conveying work of the device;

s5: when the device is in a carrying process, the driving wheel starts to move on the convex through hole, the moving driving wheel drives the connecting frame to start working, the moving connecting frame can start to move on the horizontal sliding rail under the matching of the horizontal sliding block, the grabbing arm can move to the position above a product, grabbing work is finished, and when the conveying motor moves reversely, the horizontal sliding block moves reversely on the horizontal sliding rail at the moment, and the product can be placed on a sheet;

s6: when the product is positioned on the sheet, the transportation equipment starts to work at the moment, the moving transportation equipment conveys the product to the welding equipment, the welding equipment completes the welding work on the product, the product after the welding work is conveyed to the detection equipment under the driving of the transportation equipment, and the detection equipment completes the detection work on the product after the welding machine and feeds back the detection result to the operating system;

s7: when the operation system receives the information fed back by the detection equipment, the operation system judges that the product is an unqualified product according to the fed back information, the material distribution motor starts to work, the moving material distribution motor drives one of the first connecting rods to start to work, the moving first connecting rod drives the second connecting rod to start to move on the support frame, the moving first connecting rod also drives one of the third connecting rods to start to move, when the second connecting rod starts to work, the moving second connecting rod drives the other first connecting rod to start to work, and the moving first connecting rod drives the other third connecting rod connected with the first connecting rod to start to move, so that the driving work of the device is completed;

s8: and then after the third connecting rod began to move, the third connecting rod that moves this moment drove the transmission shaft and began to work, and then the transmission shaft that moves drove the connecting piece and began to work, and then the connecting piece that moves drove the guide bar and began to work, and then the guide bar that moves can make the product on the transportation equipment skew set transportation track, and then accomplish the rejection work of product, transported unqualified product to the designated area.
