What are the maintenance items for the automatic soldering machine during operation?

During the soldering process of the soldering robot, the solder joints should not be too saturated and should be in the middle of three or four points. Otherwise, the solder joints will be too large and they will be easily disconnected from the nearby solder joints. The tin should be in a small semi-circular shape with the component feet. And the lead wire of the soldering robot should not be too thin or too long, the voltage drop during welding should not be greater than 5% of the initial voltage, and gloves, protective glasses should be worn during operation. Do not put the tip of the soldering iron on the sponge for cleaning during the use of the soldering equipment, just put the tin on the tip of the soldering iron into the tin box, so that the temperature of the tip of the soldering iron will not drop rapidly. Finally, after the soldering device is used up every day, clean it first, add enough tin, and then cut off the power immediately, which will help the machine's service life increase.

What should be paid attention to during the operation of the automatic soldering machine?

First, choose suitable solder, low melting point solder wire for soldering electronic components. Second, the flux is used as a flux by dissolving 25% rosin in 75% alcohol (weight ratio). Third, the soldering robot should be tinned before use. The specific method is to heat the electric soldering iron, and when it can melt the solder, apply the flux, and then apply the solder evenly on the soldering iron tip to make the soldering iron tip uniform a layer of tin. Fourth, the soldering method of soldering equipment is to polish the pads and component pins with fine sandpaper and apply flux. Dip a proper amount of solder with the soldering iron tip and touch the solder joints. After the solder on the solder joints is all melted and immersed in the component leads, the soldering iron tip is gently lifted up and away from the solder joints along with the pins of the components.

Fifth, the soldering equipment welding time should not be too long, otherwise, the components will be easily burnt. If necessary, tweezers can be used to clamp the pins to help dissipate heat. Sixth, the solder joints of the soldering equipment should be in the shape of sine wave peaks, the surface should be bright and smooth, free of tin horns, and the amount of tin should be moderate. Seventh, after the soldering tool is completed, the residual flux on the circuit board should be cleaned with alcohol to prevent the carbonized flux from affecting the normal operation of the circuit. Eighth, the integrated circuit should be soldered last, and the electric soldering iron should be grounded reliably, or the residual heat should be used for soldering after power failure. Or use dedicated sockets for integrated circuits, and then plug in the integrated circuits after soldering the sockets. The soldering machine should be placed on the soldering iron stand.
