Detailed Description

In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 4, in the present embodiment, the welding station is composed of a main body unit 1 and a service unit 2.

The main body unit 1 comprises a welding room 10, a rotary table 20, a welding robot 30 and a main bottom plate 40, wherein the welding room 10 is arranged on the main bottom plate 40 to protect the whole welding station, so that the influence of laser on the outside in the welding process is prevented, the middle part of the front end of the welding room 10 is protruded, the lower part of the welding room is retracted, and a feeding hole is reserved in the upper part of the welding room 10, so that the functions of wrapping the rotary table 20 and meeting the requirements of man-machine engineering are met, and the feeding and; revolving stage 20 is installed on main bottom plate 40, welding robot 30 is installed at revolving stage 20 rear, the installation face is circular on revolving stage 20, there are two stations on the revolving stage 20, towards welding robot 30 be inside the welding room, towards the feed inlet be outside the welding room, the welding room is inside respectively to have a station with the welding room outside, when one of them station is when the welding, another station can go on unloading work in the welding room outside, all there is light screen 21 between the station of revolving stage 20, prevent that the laser is outer to leak, welding robot 30 front end is welding head 31, welding robot 30's body drives welding head 31 and carries out weldment work to the work piece on the station.
