Technical Field

The utility model relates to an industrial manufacturing field specifically is kinds of exchange based on PLC hinder welds robot system.

Background

When the welded product and welding parameters are large, the product is large, the number of holes is large, and the shape is irregular, the production efficiency is often reduced by using a manual welding mode.

The manual welding mode is easy to operate artificially, for example, welding parameters required by different types of products or different welding spots of the same type of products are different, manual operation may neglect the switching of the welding parameters, so that the welded products are unqualified, potential safety hazards are brought to the use of the following products, welding sparks are splashed greatly, hands are easily injured by clamping or skins are easily scalded, and safety accidents are caused. Moreover, the manual welding method itself requires a lot of human resources, and also requires training of welding operators, which undoubtedly increases the cost. These are all disadvantages of the prior art.
