1. A welding method based on automatic welding equipment for USB wires is characterized by comprising the following steps:

1) peeling a USB cord: manually placing a USB cotton rope to be cut in the left and right sliding grooves, driving a cylinder rod connected with the left end of a peeling mechanism cylinder to extend out by a peeling mechanism cylinder I to push a pushing plate connected with the left end of the cylinder rod to move leftwards, so as to push a pushing block connected with the upper end of the pushing plate to move leftwards, moving the USB cotton rope to be cut in the left and right sliding grooves to be right below a peeling mechanism cylinder II under the pushing of the pushing block, enabling the peeling mechanism cylinder II to move downwards to press the USB cotton rope to be cut, then enabling peeling mechanism cylinders located on two sides of the peeling mechanism cylinder II to act, pushing cutting cylinders connected with the peeling mechanism cylinder III through a triangular fixing plate to move from two sides to the middle to clamp the USB cotton rope to be cut, then enabling the peeling mechanism cylinders on two sides to move reversely to peel off the USB cotton rope to be cut, then, the first peeling mechanism cylinder contracts, the pushing block presses down to move rightwards, the pushing block bounces after the first peeling mechanism cylinder acts in place, then the first peeling mechanism cylinder extends out again to drive the pushing block to move leftwards, and therefore the USB wire rope to be cut after peeling is pushed to the next station;

2) USB cord transport: the first conveying mechanism cylinder moves rightwards, the mounting plate above the first conveying mechanism cylinder is pushed to move rightwards, so that the second conveying mechanism cylinder, the cylinder extension rod, the rectangular fixing plate and the shifting claw are driven to move rightwards, then the first conveying mechanism cylinder moves downwards, the rectangular fixing plate and the shifting claw are driven to move downwards until the lower end of the shifting claw is lower than the upper end of the USB cord, and then the first conveying mechanism cylinder moves leftwards, so that the peeled USB cord to be sheared is shifted to move leftwards to the next station;

3) welding assistance of a USB wire rope: the welding-assistant mechanism cylinder acts to push the rack connected with the welding-assistant mechanism cylinder to act, and the rack drives the gear meshed with the rack to rotate in a small amplitude, so that the shaft connected with the gear is driven to rotate, the bracket connected with the shaft is driven to rotate in a small amplitude, and the scaling powder is uniformly coated on the peeled USB cord;

4) soldering the USB and the USB cord: feeding a USB on a vibrating disc, moving the USB to a specified position along a vibrating disc track, moving a cylinder I of a soldering mechanism to move to push the USB into a conveying groove, moving a cylinder II of the soldering mechanism to push the USB to a screw nut device along the conveying groove, then moving the screw nut device to drive an air claw on the screw nut device to move above the USB, clamping the USB by the air claw, moving the screw nut device again to drive the air claw to move, conveying the USB to a position to be soldered by the air claw, then moving the cylinder III middle of the soldering mechanism to drive a workbench to move towards the middle, pushing a tin wire pressing device to fast forward towards the middle, pressing a tin wire by the tin wire pressing device, then moving the tin wire pressing device slowly below a tin wire melting hot plate by the four actions of the cylinder IV of the soldering mechanism to push the tin wire melting hot plate to move downwards to the tin wire, melting the tin wire on a USB cord, then, the long motor acts to drive the horizontal screw rod to rotate, the horizontal screw rod drives the screw rod nut to move towards the middle, so that the welding machine is pushed to fast forward towards the middle, then the soldering mechanism cylinder acts six times to push the welding machine to slowly advance to a specified position, then the welding machine is started, and the USB cord are welded together;

5) lifting the welded USB: the vertical screw rod acts to drive the rectangular screw rod nut to translate downwards, so that the welded USB descends to the belt;

6) and (3) carrying by the welded USB: the motor acts to drive the belt to rotate rightwards, so that the welded USB is conveyed rightwards to the next station, and all the mechanisms reset.
