Description

An automatic transplanting device for SMT production line

Technical Field

The utility model belongs to the technical field of soldering machines, in particular to an automatic transplanting device for an SMT production line.

Background Art

Circuit boards are commonly used control devices. After the plug-in is inserted into the existing circuit board, the connecting pins of the plug-in need to be soldered and fixed. Therefore, an automatic plug-in soldering machine is used to assist the soldering of the circuit board plug-in. Among the existing soldering equipment, small soldering machines are widely used. Among them, small laser soldering machines are laser soldering technologies that have developed rapidly in recent years. Compared with the traditional electric soldering iron process, laser welding technology is more advanced, and the heating principle is also different from the former. It is not simply replacing the heating part of the soldering iron. Laser belongs to "surface heat release" and the heating speed is extremely fast, while the soldering iron relies on "heat transfer" to slowly heat up. For example, a fully automatic soldering machine announced by announcement number CN206578409U.

The Y-axis slide of the above-mentioned conventional automatic soldering machine is separately arranged on the base frame, and the positioning table can move on the Y-axis slide, and then the circuit board is sent to the soldering position. When the above-mentioned positioning table is fixing the circuit board, each circuit board will be fixed with a corresponding positioning fixture, and the positioning fixture is fixed on the positioning table. In this way, when the operator fixes different circuit boards, it is necessary to constantly disassemble and replace the positioning fixture back and forth, which makes the operation very troublesome. In order to solve the above-mentioned problems, an automatic transplanting device for an SMT production line is provided.
