An automatic immersion tin angle cutting machine and angle cutting method for welding

Abstract

The invention discloses an automatic immersion tin angle shearing machine for welding, which comprises an angle shearing machine body, a discharge trough, a grinding structure, a motor, a limit bar, a first rotating shaft, a conveying wheel, a first gear, a second gear, and a second gear. Two rotating shafts, grinding rollers and cleaning structure. The beneficial effects of the present invention are: after the dipping and angle-cutting operation of the circuit board is completed through the angle shearing machine body, the circuit board is transported into the discharge trough, and the limit strips arranged on both sides of the discharge trough can control the processed parts. The circuit board is guided. As the circuit board is transported to the conveying wheel, the toothed structure on the side of the conveying wheel can push the side of the circuit board. The conveying wheel is driven by the motor to rotate, and the conveying wheel will drive the circuit board to continue to move forward. , through the transmission effect of the first gear and the second gear, the grinding roller on the bottom side starts to rotate, and the grinding roller will grind the pin part on the bottom side of the circuit board, so as to solve the situation that the pin is too sharp and avoid damage to workers cause scratches.

Description

technical field [0001] The invention relates to an angle cutting machine, in particular to an automatic dipping tin angle cutting machine for welding and an angle cutting method, belonging to the technical field of welding. Background technique [0002] Dip soldering is a multi-point welding method that is widely used in plug-in technology and SMT red plastic surface. Using manual or machine, a large amount of tin is boiled and melted, and the welding surface is immersed to make the solder joints tinned. At present, factories often use manual dip-soldering method to dip-solder the PCB circuit board or MT red plastic surface, use manual clamping of the workpiece and spray flux, and then put it into the tin furnace for dip-soldering. The soldering quality is controlled by the technical level of the personnel. , The worker's slight inappropriate actions such as preheating time, tin dipping depth, dipping time, etc. will affect the product quality, and the gas emitted during man...

AI Technical Summary

Problems solved by technology

At present, factories often use manual dip-soldering method to dip-solder the PCB circuit board or MT red plastic surface, use manual clamping of the workpiece and spray flux, and then put it into the tin furnace for dip-soldering. The soldering quality is controlled by the technical level of the personnel. , The worker's slight inappropriate actions such as preheating time, tin dipping depth, dipping time, etc. will affect the product quality, and the gas emitted during manual dipping soldering is harmful to the human body, and it is dangerous when frying tin improperly. When the product consistency is not high

There are also some factories that use automatic dip soldering machines, which also need to manually clamp the workpiece and spray flux, and then place it on the dip soldering platform to realize automatic dip soldering. The soldered circuit board has to be taken out manually, which is not efficient, and this The dip soldering machine cannot adjust the dip soldering angle during dip soldering, and the soldered products have problems such as continuous soldering, virtual soldering, and unclean board surface.

[0003] When the circuit board is processed by a fully automatic dipping tin cutting machine, the pins of the circuit board that have been cut at the end are relatively sharp, which may cause scratches to subsequent assemblers
