Abstract

The invention discloses a laser welding head, and belongs to the technical field of laser remelting equipment. The laser welding head comprises a base plate, wherein a fixing block and a storage bin are installed on the base plate, the lateral wall of the fixing block is respectively provided with an air inlet and a feeding passage, a tin outlet nozzle is installed at the bottom of the fixing block, a laser device optical fiber head is installed at the top of the fixing block, a discharging through hole is formed in the bottom of the storage bin, the base plate is provided with a falling passage communicated with the feeding passage, a material dividing sliding block driven by a linear driving device is installed on the base plate in a sliding mode, and a positioning hole is formed in the material dividing sliding block. The invention further discloses a laser welding machine with the laser welding head. The laser welding head and the laser welding machine are simple and reliable in structure, small and exquisite in size, light in weight and low in cost. Nitrogen is blown in for protection at the same time of laser remelting welding, and welding point formation and appearance are good.

Description

technical field [0001] The invention belongs to the technical field of laser remelting equipment, and in particular relates to a laser welding head and a laser welding machine. Background technique [0002] In recent years, foreign countries have attached great importance to the research and development of laser remelting methods and equipment. With the development of robot technology and the improvement of laser performance, the application field of laser remelting is constantly expanding, especially in the welding of special-shaped components, which plays an increasingly important role. Among them, the automation and stability of the solder ball feeding mechanism of the laser welding head are very important to the equipment. [0003] At present, the solder ball feeding mechanism of the existing laser welding head uses a servo motor to drive the disk to rotate, and separates and transfers the solder balls individually. Due to its complex structure and many parts, the over...
