The method for using the electronic component spot welding device according to any one of claims 1 to 7, characterized in that: The following steps are involved: S1, first placing the electronic components on the vibrating tray (2), then conveying the electronic components to the bracket (52) through the vibrating tray (2), then starting the cylinder (51), the output end of the cylinder (51) drives the bracket (52) to rise, and lifts the electronic components upward to the same height as the positioning block (78), during which the support rod (53) drives the slideway (54) to move, and the slideway (54) will not hinder the rise of the bracket (52); S2, starting the telescopic end of the electric telescopic rod (72) to retract, driving the square block (73) to move, causing the connecting rod 1 (74) and the connecting rod 2 (76) to move, driving the L rod (77) to stably move in the direction of the bracket (52), driving the positioning block (78) to position the electronic components, and realizing the positioning of the electronic components. In this process, after the positioning block (78) contacts the electronic components, the L rod (77) continues to move to squeeze the connecting spring, and when the pressure sensor (782) reaches a specified pressure, it transmits an electrical signal to the controller (101), and then the electric telescopic rod (72) is closed through the controller (101), and then the cylinder (51) is started, so that the cylinder (51) drives the bracket (52) to descend and reset; S3, the slider (781) is driven to slide in the positioning block (78) by the L rod (77), and the linkage rod (794) drives the vertical rod (793) to move, so that the piston block (792) squeezes the gas in the jet chamber (791), and the gas is ejected from the one-way jet port (796), thereby cleaning the dust on the electronic components. When the slider (781) is reset, the piston block (792) slides and resets, and the outside air is filtered by the filter screen (7951) and enters the jet chamber (791) through the one-way valve port of the air inlet (795) and the slip ring (7952); S4, adjusting the position of the spot welding mechanism (6) by means of the adjusting mechanism (4), and then starting the electric cylinder (63), so that the output end of the electric cylinder (63) drives the welding machine (64) to descend, and then spot welding is performed on the electronic components; S5. After the spot welding operation is completed, the telescopic end of the electric telescopic rod (72) is started to extend, so that the positioning block (78) releases the positioning of the electronic components, and the welded electronic components fall onto the slideway (54), and then slide onto the conveyor belt (8), and then the welded electronic components are transported away by the conveyor belt (8).
