Huirui laser cladding head is a core product independently developed and launched by Huirui that is suitable for various laser cladding applications. It has diversified interface settings and can be used with various lasers to achieve high efficiency and stability in industrial laser cladding applications. long hours of work.

The laser cladding head mainly provides laser path transformation and focusing for laser cladding to generate sufficient energy density to melt the metal powder. It is divided into straight type and turning type according to the different optical paths. A protective mirror module is provided above the collimation module to protect the collimating lens from being contaminated by the optical fiber plug during the plugging and unplugging process; a protective mirror module is provided below the focusing module to protect the focusing lens from the impact of sputtering during the cladding process.

Optional module description

1. Imaging module: It can realize debugging and correction based on the cladding condition of the substrate surface through coaxial illumination;
2. Real-time imaging and closed-loop feedback control: The size, shape, temperature, etc. of the molten pool formed by laser cladding can be monitored in real-time, and relevant parameters can be captured and fed back to the control system in real-time for real-time adjustment to obtain more stable and high-quality results. Cladding effect;
3. Shaping module: It can realize the output of a strip-shaped large light spot and greatly improve the cladding efficiency.

Laser cladding head quick change device

The quick-change device developed by Huirui realizes the connection between the robot and the laser head and quickly switches the laser head of different specifications with the robot. It can be freely switched in a variety of processes. With the rotating platform, it can adapt to workpieces of various shapes, materials, and sizes. Cladding and welding process requirements.

Switching the tool head requires manual operation by the operator. The specific steps are as follows:

1) Ensure that all energy sources in the equipment are safely cut off;
2) Clean the dust, welding slag, powder, etc. around the tool head, pull out the optical fiber, and put on the safety plug;
3) Cut off the powder feeding pipe, protective gas, and other pipelines between the powder feeder and the cladding head;
4) Loosen the quick-change joint and remove the high-speed cladding head;
5) Replace the wide-band cladding head and lock the quick-change joint;
6) Connect the optical fiber, and connect the cooling water protective gas powder supply pipe, etc.;
7) Power on the equipment and prepare for work.
