[0024] A method for using a welding device comprises the following steps: S1. The bearing shell is placed on the surface of the conveyor belt, and the magnet bar is inserted into the groove to cooperate with the adsorption iron sheet to realize the adsorption and fixation of the bearing shell. The plate to be welded is placed on the surface of the bearing shell, and the conveying motor is started. The conveying motor cooperates with the conveying shaft and the conveying roller to drive the conveyor belt to move, thereby driving the bearing shell to move; S2. When the bearing housing moves to the point where the infrared receiver is facing the infrared induction switch 1, the infrared induction switch 1 will start the left and right driving motors, which will drive the two-way lead screws to rotate, thereby driving the two threaded seats 1 to move relative to each other, and then driving the two left and right clamping plates to move relative to each other through the connecting plate 1, thereby fixing and clamping the left and right sides of the plate; S3, when the bearing shell moves to the point where the infrared receiver is facing the second infrared sensing switch, the second infrared sensing switch will start the front and rear driving motors, which drive the disc to rotate, and then drive the pulling frame to drive the second connecting plate to move in cooperation with the articulation of the articulated arm, and then drive the two front and rear clamping plates to move, so as to fix and clamp the front and rear sides of the plate; S4. When the bearing shell moves to the point where the infrared receiver is facing the infrared induction switch 3, the infrared induction switch 3 will start the fan and the heating screen at the front position. The fan blows air and the heating screen generates heat to achieve the preheating effect of the plate. S5. When the bearing shell moves to the point where the infrared receiver is facing the infrared induction switch 4, the infrared induction switch 4 will drive the conveying motor to stop working, and the conveyor belt will stop conveying at the same time, and the cylinder will be driven to move downward, and the cylinder will drive the adjusting shell 1 to move downward, and the adjusting shell 1 will drive the adjusting shell 2 to move downward, and then drive the welder to move downward close to the plate, and at the same time, the adjusting motor drives the adjusting screw to rotate, and then drives the threaded seat 2 to drive the connecting plate 3 to move left and right, and then drives the adjusting shell 2 to move left and right, and then drives the welder to move left and right, and at the same time, the electric push rod is extended to drive the mounting seat to move forward and backward, and then drives the welder to move forward and backward, thereby completing the welding operation; S6. After one welding is completed, the conveying motor is started again, the conveying belt continues to move, the bearing shell continues to move, and when the next bearing shell moves to face the infrared sensor switch, the conveying is stopped again and welding is performed, and this reciprocating process is repeated to realize intermittent continuous welding operation; S7. When the bearing shell of the welded plate moves to the point where the infrared receiver is directly opposite to the infrared induction switch 5, the infrared induction switch 5 will drive the fan at the rear side to work, thereby achieving a cooling effect on the plate; S8, when the cooled bearing housing moves to the point where the infrared receiver is directly opposite to the infrared sensing switch 6, the infrared sensing switch 6 will drive the left and right driving motors to work in the reverse direction, thereby making the two left and right clamping plates move away from each other and detach from the panel, thereby unlocking the left and right sides of the panel; S9, when the cooled bearing housing moves to the point where the infrared receiver is directly opposite to the infrared sensing switch 7, the infrared sensing switch 7 will drive the front and rear driving motors to work in the reverse direction, thereby causing the two front and rear clamping plates to move away from each other and detach from the panel, thereby unlocking the front and rear sides of the panel; S10. When the load-bearing shell moves to the splitting grooves at the upper and lower positions of the lower splitting bar and the upper splitting bar after the panel is unlocked, the upper splitting bar will lift the panel on the load-bearing shell to the surface of the upper splitting bar, and the lower splitting bar will lift the load-bearing shell to the surface of the lower splitting bar and detach from the conveyor belt, thereby realizing the separation and unloading of the load-bearing shell and the panel.
