Description

Technical Field

[0001] The invention relates to the technical field of metal processing, and in particular to a multi-degree-of-freedom welding robot arm for processing metal steam cabinets. Background Art

[0002] The rice steaming cart, also known as the rice steaming cabinet, rice steaming machine or rice steaming box, refers to a large kitchen baking device that uses electricity or gas to heat and steam rice. The interior uses a stainless steel steaming plate (stainless steel square plate) as a container. In order to facilitate movement, universal wheels are installed under the equipment, so the appearance is like a car. The body is cabinet-shaped and is generally made of stainless steel. Rice steaming carts are mostly used in large canteens such as hotels, troops, schools and factories. In the welding process of steaming cabinet assembly, the most common is the welding of the box structure of the steaming cabinet. The manipulator is an automatic operating device that can imitate certain movements and functions of human hands and arms to grasp, carry objects or operate tools according to a fixed program. The characteristic is that it can complete various expected operations through programming. The structure and performance have the advantages of both human and mechanical machines. The manipulator is the earliest industrial robot and the earliest modern robot. It can replace the heavy labor of people to realize the mechanization and automation of production. It can operate in a harmful environment to protect personal safety, so it is widely used in the welding operation of metal steaming cabinets.

[0003] Conventionally, when welding metal cabinet panels, the metal cabinet panels are placed on a welding table and then welded by a welding robot arm. However, this method still cannot cover all surfaces to be welded, and the metal cabinet panels to be welded need to be placed manually, thereby increasing the workload of the staff during the entire welding process, while reducing the processing efficiency of the welding robot arm, and failing to perform local cooling operations on the welding points, resulting in welding deformation.
