Description

Technical Field

[0001] The invention relates to the field of mechanical automation, in particular to a mechanical automation welding system. Background Art

[0002] With the booming development of modern manufacturing, the requirements for welding technology in the mechanical processing industry are constantly rising. Automated and intelligent production has become the mainstream trend. In order to improve production efficiency, reduce labor costs, and improve product quality stability, enterprises are in urgent need of advanced mechanical automated welding systems. Especially in the fields of automobile manufacturing, aerospace, mechanical equipment, etc., high-precision and high-efficiency welding equipment is a key factor in improving industrial competitiveness, which also provides a broad market space and opportunities for the innovative development of welding technology.

[0003] There are many problems with the mechanical automated welding equipment currently on the market. The loading process of some equipment is not accurate and efficient enough, resulting in inaccurate positioning of parts, affecting welding quality and subsequent processing procedures. Moreover, the welding parameter adjustment flexibility of many equipment is poor, making it difficult to meet the diverse needs of welding of different materials and complex structures. In addition, some equipment is not convenient enough in the design of material supply systems and fixtures, material replacement is time-consuming and labor-intensive, and the adaptability of fixtures is poor, which reduces overall production efficiency and increases the operating and time costs of enterprises.

[0004] Traditional mechanical automated welding equipment usually manually places the welding parts in a fixed loading position first, and then transports the parts to the welding area through a simple mechanical transmission device. This loading method is prone to part offset. In terms of welding parameter setting, there are often only limited preset mode options, and it is impossible to flexibly fine-tune according to the actual welding situation. For the position adjustment of the welding head, a relatively single fixed track or a simple manual adjustment method is generally used, which makes it difficult to achieve precise positioning at multiple angles. In terms of material supply, the material tank usually adopts a complex connection structure, and professional tools are required for replacement. The operation is cumbersome and time-consuming, which is not conducive to efficient production.

[0005] The shortcomings of existing technologies in feeding accuracy can easily lead to quality problems such as misaligned welding joints and uneven welds, increase the defective rate, and raise production costs. The welding parameter adjustment is inflexible and cannot adapt to new materials and complex process requirements, limiting product innovation and quality improvement. The inconvenience of material supply systems and tooling fixtures leads to long equipment downtime and low production efficiency, making it difficult to meet the large-scale, high-efficiency, and high-precision production needs of the modern manufacturing industry, weakening the competitiveness of enterprises in the market and being detrimental to the sustainable development and progress of the industry.
