Spot-welding and arc-welding integrated station and control method thereof

Abstract

The invention provides a spot-welding and arc-welding integrated station and a control method thereof. The spot-welding and arc-welding integrated station comprises a spot welding device, an arc welding device, a robot, a clamp and a station plate, wherein the robot comprises a welding manipulator and a robot controller; a welding arm is arranged on the welding manipulator; the tip of the weldingarm is provided with an assembly disc used for assembling a spot welding torch; an assembly plate used for assembling an arc welding torch is arranged on one side edge of the welding arm; the distancebetween the spot welding torch and the arc welding torch which are arranged on the welding arm is greater than the length of a to-be-welded workpiece; the clamp is provided with an infrared sensor used for detecting whether the to-be-welded workpiece exists or not and a plurality of displacement sensors; and a spot welding station which is opposite to the spot welding torch and an arc welding station opposite to the arc welding torch are arranged on the station plate. The spot-welding and arc-welding integrated station has the beneficial effects that use of spot welding and arc welding on thesame station is realized, and change and use of a spot welding machine and an arc welding machine are flexible.

Description

technical field [0001] The invention relates to a welding device, in particular to an integrated arc spotting station and a control method thereof. Background technique [0002] Spot welding is usually divided into two categories: double-sided spot welding and single-sided spot welding. During double-sided spot welding, the electrodes are fed from both sides of the workpiece to the weld. The typical double-sided spot welding method is the most commonly used method, when there are electrode indentations on both sides of the workpiece. The conductive plate with a large welding area is used as the lower electrode, which can eliminate or reduce the indentation of the workpiece below. Commonly used for spot welding of decorative panels. Double-sided spot welding of two or more spot welds at the same time, using a transformer to connect the electrodes in parallel, at this time, the impedance of all current paths must be basically equal, and the surface condition, material thick...

Problems solved by technology

[0004] Therefore, the shortcoming that exists in the prior art is: some special parts need both spot welding and arc welding; Workstation, which not only increases the investment of equipment, but also takes up a larger area of ​​the factory building, and at the same time requires a greater investment in labor costs and later maintenance costs, and also reduces production efficiency; in addition, if only Putting the traditional spot welding workstation and the arc welding workstation together, the spot welding workstation and the arc welding workstation will interfere with each other and affect the welding effect
