1. The workpiece loading and unloading mechanism of the all aluminum whole plate welding machine
For a set of automatic welding machines, different loading and unloading mechanisms need to be set up according to the weld seam form and size of the workpiece. Considering China's national conditions and the cost bearing capacity of most domestic enterprises, many still choose manual loading and unloading. On welding production lines for automobiles or household appliances, a large number of robotic arms or automated mechanical structures are used for automatic loading and unloading, including conveying, lifting, flipping, transferring and other actions, in order to achieve fast production and an automatic welding system without human intervention.

2. Automatic conversion device for workpiece welding station

　　In the all aluminum whole plate welding machine system, in order to improve welding efficiency, it is often necessary to make multi station automatic welding, mainly including loading position, clamping position, welding position, cooling position or detection position, and unloading position, to form a complete set of automation system, completing the work of workpiece assembly, welding, detection and output in one go. The picture on the right shows a three station automatic welding machine for car push rods and push plates, with loading and unloading positions, welding positions, and detection positions. In automatic welding machine systems composed of welding robots, dual or multi station welding is often used. Within the coverage range of the robot's long arm, it is possible to switch from one station to another, thus achieving multi station welding.
The welding work of components often involves one or more welds, as well as multiple parts being welded together into one part. For example, the commonly used water heater inner liner and car air storage cylinder, including straight seam welding after steel plate rolling, circumferential seam welding between the two end heads and the cylinder, circumferential seam welding between the water outlet nozzle or air outlet nozzle and the cylinder or end cover, hanging bracket welding of the inner liner or cylinder, are assembled and welded into one component, namely the water heater inner liner or air storage cylinder. To achieve automatic completion of each welding method, it is necessary to automatically switch from one workstation to another, thereby forming a streamlined production operation and achieving automatic welding.
