Description

TECHNICAL FIELD

[0001] The present application relates to the field of welding equipment, in particular to a cross plate welding equipment and an operating method thereof. BACKGROUND

[0002] At present, the Chinese invention with the publication number CN108817783B discloses a welding equipment for automatic welding of pipe materials, which comprises a welding robot, a first positioning part for positioning one end of the pipe material, and a second positioning part for positioning the other end of the pipe material, which is movably arranged relative to the first positioning part. The first positioning part and the second positioning part form a positioning space for positioning the pipe material, and the first positioning part and the second positioning part are relatively close to position the pipe material in the positioning space, and the welding robot is used for welding the positioned pipe material. The welding equipment of the invention solves the problem that the welding equipment in the prior art cannot meet the welding of pipe materials of different lengths.

[0003] Although the existing welding equipment has a single clamping component to fix products of different lengths, there are still other problems in the use process, such as poor welding effect. The cross plate is composed of one long plate and two short plates before welding, and the two short plates are welded on both sides of the long plate to form a "cross shape". It is difficult to handle the short plate under the condition of one-sided limiting of the long plate, so personnel often need to hold the short plate and align and tighten it towards the long plate, which is time-consuming and laborious, and it is difficult to guarantee the quality of the welding part. Moreover, the welding equipment does not have dust collection and purification function. A large amount of smoke and dust will be generated during the welding process of the product, which will carry light particles and harmful substances. If not collected and treated in time, it will quickly dissolve in the air and be inhaled by the human body, which not only poses a great threat to human health, but also damages the surrounding environment and causes pollution, increasing the cleaning burden of personnel. In order to solve the above problems, we propose a cross plate welding equipment and an operating method thereof. SUMMARY
