Description

Technical Field

[0001] The utility model relates to the technical field of lead-based alloy plate welding, in particular to an automatic welding workstation for lead-zinc plates. Background Art

[0002] Lead-based sheet metal welding involves welding two lead-based alloy components, called plates and conductive rods, into a single component. Currently, lead-based alloy sheet metal welding relies primarily on manual welding. Before welding, the plates and conductive rods must be hoisted onto a simple welding positioning platform and manually aligned. After the assembly is complete, the welding process is performed manually, holding a welding torch in one hand and a welding rod in the other. Manual welding requires significant labor for hoisting and assembly, due to the large size, weight, and soft texture of the plates and conductive rods. This leads to low efficiency, poor weld quality, and the generation of hazardous gases that pose health risks. Utility Model Content

A welding machine 100.1 and a cooling water tank 100.2 are provided at one end of the welding robot 100, and a controller is provided at the top of the welding machine 100.1.

[0031] The suspension arm 300 and the punching machine 400 are located at one end of the first positioner 200. A suspension arm clamp 300.1 is provided at one end of the suspension arm 300. The suspension arm clamp 300.1 clamps the workpiece for loading and unloading. The suspension arm clamp 300.1 includes a clamp bracket 300.1.1 and a plurality of suction cups 300.1.2. The suction cups 300.1.2 are provided at the bottom end of the clamp bracket 300.1.1. The punching machine 400 removes excess scraps of the conductive rod.

[0032] The dust collector 500 and the safety fence 600 are located at the other end of the first positioner 200; the dust collector 500 collects and processes harmful gases generated during the welding process;
