Abstract

The invention relates to an automatic circuit board straight-insert device welding machine which comprises a machine frame, a driving assembly, a welding device and a turning structure. The driving assembly is installed at the upper portion of the machine frame and provided with the welding device and drives the welding device to horizontally reciprocate. The turning structure is installed at the corresponding portion, below the welding device, in the machine frame. According to the welding machine, liquid soldering tin can be evenly distributed on welding spots through high-pressure air spraying, holes of the welding spots can be well filled with the soldering tin due to a certain initial speed, the solder splash accumulation problem is solved, welding quality is effectively ensured, and product percent of pass is increased.

Description

technical field [0001] The invention belongs to the field of circuit board welding, and relates to the welding of in-line electronic devices, in particular to an automatic welding machine for circuit board in-line devices. Background technique [0002] The components on the circuit board are divided into patch type and in-line type. The in-line device welding method is: use an electric soldering iron to melt the solder, use gravity and fluidity of the liquid to flow the solder into the solder joint hole, and wait for the solder to naturally Secure the in-line inserts after cooling. The welding efficiency of this method is low, and the liquid solder has a certain viscosity and sticks to the tip of the soldering iron and is not easy to fall off. The tip of the soldering iron is easy to oxidize, and the introduction of impurities affects the welding quality. The high temperature of the soldering iron is easy to burn components and circuit boards. [0003] At present, mass prod...
