Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding, and in particular relates to a laser incremental tracking positioning welding robot. Background Art

[0002] Welding robots can easily replace manual labor to perform perfect welding. Robot welding can also improve the labor intensity of workers, work in harmful environments, and replace many complex tasks that are not suitable for human labor and are harmful to health.

[0003] In the prior art, after searching, Chinese patent number CN213614779U discloses a laser tracking welding robot; it includes a working platform and side panels, a numerical control box is installed on the outer side of the side panels, and also includes a mounting block, a track rod is fixed to the inner top end of the two side panels, and a displacement mechanism for driving the mounting block to move is installed on the side panel; a telescopic rod is installed on the bottom surface of the mounting block, and a laser welding head is fixed at the bottom end of the telescopic rod; an infrared signal transmitter is installed on the outer side of the mounting block, and an infrared signal receiver is installed on the top surface of the working platform; through the improvement of the displacement mechanism and the track rod, the sensitivity of the welding robot is enhanced, and the position deviation caused by inertia is avoided while ensuring work efficiency, thereby increasing product quality, reducing costs and facilitating the use of users; the initial height of the working platform is adjustable, so that the device is suitable for welding objects of different sizes, with high compatibility and a wide range of applications.

[0004] The above scheme transmits a signal through the infrared signal transmitter. When it moves with the laser welding head to the top of the infrared signal receiver, the infrared signal receiver receives the signal, thereby stopping the laser welding head from moving and completing the welding. However, the laser welding head can produce granular smoke during the welding process of the workpiece, which can easily cause it to adhere to the transmitting end of the infrared signal transmitter and the receiving end of the infrared signal receiver, blocking them and affecting the transmission and reception of the signal, which can easily cause deviations in the welding process.
