Description

Welding machine

Technical Field

The utility model relates to the technical field of welding equipment, in particular to a welding machine.

Background

In the industrial field, the mutual fixing of the components is achieved in many cases by means of welding. For example, in the automobile tire pressure sensor industry, the relevant circuit board on the tire pressure sensor is fixed on a metal support piece in the shell of the tire pressure sensor in a welding mode, so that the connection firmness between the two is enhanced, and the problem that the circuit board loosens from the metal support piece due to jolt vibration generated in the high-speed running process of an automobile, so that the tire pressure sensor fails and the automobile tire pressure data cannot be monitored is avoided.

The welding is realized by a welding machine. The welding machine is provided with a welding wire feeding mechanism, a welding head and a heating device for heating the welding head. When the welding machine welds workpieces, the welding wire feeding mechanism pushes welding wires with proper lengths to the vicinity of the workpieces to be welded, then the welding heads heated by the heating device are contacted with the welding wires, the welding wires are melted at high temperature and drop between the two workpieces to be welded, and the two workpieces are welded together after the welding wires are cooled and solidified.

When the existing welding machine works, residual welding flux (welding slag) stays on the welding head after being cooled, so that the working part of the welding head is often wrapped by the welding slag, the heating time of the welding head is prolonged, the working efficiency is reduced, and more importantly: when the high Wen Hantou contact wire is ready to weld a workpiece, the melted slag and the solder balls formed after the melting of the wire are joined together to form larger solder balls, and therefore, when the welder works, the welded part of the welded workpiece can form a welding area with larger area, which can lead to the fact that the part around the workpiece, which does not need or cannot have soldering tin, is also coated with soldering tin, and thus, the circuit function of the workpiece is disabled. In addition, as the welding head moves, molten slag remaining on the welding head may drip onto the workpiece or other component as the welding head moves, thereby increasing the difficulty of cleaning the workpiece or working environment.

There is therefore a need for an improvement over the prior art to provide an improved welder that avoids the above-described drawbacks of the prior art.
