Laser welding accessories

Abstract

This novel laser welding accessory is used to assist in the welding operation of a scanning laser welding machine. The laser welding accessory includes a body connected to a gas supply device, a channel formed in the body, a plurality of holes formed in the body, and a receiving area enclosed by the body. The channel is connected to the outside through the holes. Therefore, by positioning the object in the receiving area and simultaneously introducing working gas into the channel through the gas supply device, and blowing it towards the welding area of ​​the object through the holes, the working gas can completely cover the welding area without interfering with the movement of the laser beam. This prevents the welding area from being affected by external air and causing oxidation, contamination, or other defects, thereby effectively improving the welding effect and quality.

Claims

1. A laser welding auxiliary tool for assisting the welding operation of a scanning laser welding machine, wherein the scanning laser welding machine melts the welding area of ​​the object to be welded with a laser beam, thereby forming a joint in the welding area; characterized in that: the laser welding auxiliary tool includes a body, a channel formed in the body, and a plurality of holes formed on the body and communicating with the channel, and the body encloses a receiving area for placing the object, wherein when the object is positioned in the receiving area, the holes are oriented toward the object, and the laser welding auxiliary tool is connected to a gas supply device to input working gas through the gas supply device, and to move the working gas along the channel and release it toward the object through the holes.

2. The laser welding fixture according to claim 1, wherein, The working gas is an inert gas.

3. The laser welding fixture according to claim 1, wherein, This system is composed of complex components.

4. The laser welding fixture according to claim 1, wherein, The body has a top surface, a bottom surface opposite to the top surface, and a connecting surface connecting the top surface and the bottom surface respectively. The holes are formed on the connecting surface. The extension length of the bottom surface is greater than the extension length of the top surface, so that the connecting surface is inclined.

5. The laser welding fixture according to claim 1, further comprising a positioning member placed on the object, the positioning member having an upper surface, a lower surface opposite to the upper surface, and a mating surface connecting the upper surface and the lower surface respectively, wherein the extension length of the lower surface is greater than the extension length of the upper surface, such that the mating surface is inclined.

6. The laser welding fixture according to claim 4, further comprising a positioning member placed on the object, the positioning member having an upper surface, a lower surface opposite to the upper surface, and a mating surface connecting the upper surface and the lower surface respectively, wherein the distance between the lower surface and the bottom surface of the body is less than the distance between the upper surface and the top surface of the body.
