Description

Technical Field

[0001] The invention relates to the field of metal material component processing, in particular to a metal material component feeding device. Background Art

[0002] Metal components refer to parts made of various metal materials used in various equipment and systems. These components are widely used in many fields such as machinery, electronics, aerospace, automobiles, and construction. Metal components play a vital role in various applications. The versatility and reliability of metal components make them indispensable in modern technology and industry.

[0003] Metal components are the foundation of many devices and structures, such as buildings, bridges, and mechanical equipment; they provide the necessary strength and stability to ensure the safety and reliability of the overall structure. Certain metal materials (such as stainless steel and titanium alloys) have good corrosion resistance and are suitable for chemical, marine, and medical fields to ensure that equipment and components can operate for a long time without damage in harsh environments. Metal materials (such as copper and aluminum) have excellent electrical and thermal conductivity and are widely used in electrical components and heat exchange equipment. These metal components help current flow or transfer and dissipate heat effectively.

[0004] These metal components produced are assembled in the corresponding production equipment and the corresponding control position, so that they can play their maximum function. In the existing production equipment assembly line, when the corresponding metal material components are assembled or moved, most of them are operated and controlled by manipulators. The existing manipulators all adopt a single clamping and moving method. A manipulator can basically only clamp and move one metal material component. For an assembly, there will be many metal material components that need to be assembled. If the assembly is on the corresponding production line, a manipulator can only clamp and move one assembly at a time, which will reduce the efficiency of production and processing; however, in order to increase production efficiency, adding manipulators will increase production costs accordingly, increasing the burden on the enterprise.
