Description

Automatic laser welding machine

Technical Field

The invention relates to the technical field of laser welding, in particular to an automatic laser welding machine.

Background

The laser welder is a machine for processing laser materials and can be divided into a laser die welding machine (manual welder), an automatic laser welder, a laser spot welder and an optical fiber transmission laser welder according to the working mode, wherein the optical welding is to use high-energy laser pulses to locally heat materials in a micro area, the energy radiated by laser is diffused into the materials through heat conduction, and the materials are melted to form a specific molten pool so as to achieve the purpose of welding.

In our real life, the various components are made of materials. The nature of the different materials, which themselves reflect the laser light, determines the magnitude to which the laser light can be affected. The higher the reflectivity, the less light energy is absorbed. Conversely, the more light energy is absorbed. The reflectivity is dependent on the material itself and also on the degree of roughening of the metal surface, the specular reflectivity is generally highest and is generally avoided as much as possible during processing, possibly causing damage to the laser. The surface of the metal is subjected to a series of changes under the action of laser, the metal is heated by the laser on the surface and is rapidly conducted like a deep part, the surface is melted under the condition of certain laser power density, and part of the metal is instantly vaporized under the condition of high laser power density to form a molten pool on the surface of a workpiece. In the welding process, the workpiece moves relative to the laser, so that the molten metal is accelerated along a certain angle, the heat transfer action temperature of the liquid metal is rapidly reduced, and the liquid metal forms a welding line.

The laser welding technology is applied to the manufacturing of foreign automobiles, and according to the investigation that the laser tailor-welding production line of blank plates exceeds 100 in 2000 all over the world, 7000 thousands of blank plates are tailor-welded by automobile components in annual output, and the laser tailor-welding production line is increased at a higher speed again. Some cutting blank plate structures are also selected for the manufacturing lead-in vehicle system in China. In Japan, the CO2 laser welding is used for replacing the flash butt welding to carry out the connection of steel rolling coils in the steel manufacturing industry, and in the research of ultra-thin plate welding, for example, foil with the thickness of below 100 mm cannot be welded, but the YAG laser welding with a special output power wave pattern is successful, and the wide development prospect of the laser welding is shown. In japan, for the first time, YAG laser welding has been successfully developed and designed for the inspection of a thin tube of a steam generator in a nuclear reactor, and a gear laser welding technology has been developed domestically.

The automatic laser welding technology developed by the company is different from the technology on the market. Traditional radium welding device places the product and carries out welding operation on the workstation of welding machine, and this kind of welding set product is placed for a long time, and the work of loading, unloading of work piece all need be carried out to welding work at every turn, and the rate of utilization of board is low, and the clamping all needs accurate positioning at every turn, and is consuming time long, and the error is big, and tight ghost image makes a sound machining efficiency and processingquality of work piece.
