Description

TECHNICAL FIELD

[0001] The utility model relates to automatic welding equipment technical field, especially in kind of automatic assembly welding equipment. BACKGROUND

[0002] In various industrial facilities, H-shaped roof beam, crane beam, purlin support plate and other components are widely used, however, the traditional assembly welding mode for these components gradually exposes many drawbacks with the progress of technology and the improvement of production requirements.

[0003] In the past loading stage, mainly rely on manual operation to complete. Workers need to carry various parts to the designated position one by one, this process not only consumes a lot of manpower and time, the efficiency is extremely low, and the workers are extremely easy to be affected by fatigue, experience and other factors when positioning parts, so as to produce errors. Once this error occurs, it will be accumulated layer by layer, and finally it is difficult to guarantee the precision of assembly welding, which seriously affects the quality of the final product, which may cause the product to deform, insufficient carrying capacity and other problems.

[0004] In the welding link, the problem is also prominent. Different welding parts usually need to be equipped with separate welding equipment and operation process. Taking H-shaped roof beam as an example, when welding the left and right parts, the welding quality may be uneven due to the differences in parameter setting and performance of the welding equipment used, or the different operation methods of the operators. Some parts have full welds and high strength, while some parts may have discontinuous welds, pores and other defects, which seriously affect the overall performance of the component.

[0005] In addition, the traditional welding device also has obvious defects in the operation process. The operation procedures such as welding wire conveying and welding module moving are relatively complicated, and the operator needs to carry out multi-step complex control. And when facing the welding demand of complex structure, it is difficult to accurately adjust the welding point, and it is impossible to flexibly and accurately weld according to different welding parts and shapes. At the same time, after the existing artificial pre-welding, the equipment carries out secondary welding, or the layout design of one assembly and one welding, which not only makes the welding efficiency low, prolongs the production cycle, but also makes it difficult to effectively guarantee the welding quality, increases the product rejection rate and the later maintenance cost.

[0050] As shown in the figure, Figure 1 The material taking module 2 includes a picking member 21 and a material taking drive 22 for driving the picking member 21 to move in multiple degrees of freedom.
