Application of laser welding machine for automobile lights

With the rapid development of the automobile industry, the production technology of automobile parts is also constantly innovating. As the lighting accessories of automobiles, lamps affect the commercialization of automobiles in terms of function and appearance. Advanced manufacturing technologies represented by laser technology have been widely used in the automobile industry, especially the application of plastic laser welding, a new technology, in lamp welding, which provides the best solution for lamp welding.

Plastic Laser Welding Technology

Plastic laser welding technology has the advantages of beautiful welding, no welding debris, welding of various plastic materials (or complex contour structures), product vibration stress and thermal stress, etc., which is very suitable for lamp welding.

Laisai Laser Welding Machinecan weld various thermoplastics and modified engineering plastics, can follow a six-dimensional trajectory, and is non-contact welding. Build a multi-axis robot for plastic laser welding, and use the multi-axis robot to use Plastic Laser Welding technology to achieve precision welding of automotive lights, convert complex spatial curves into spatial movement of the laser welding head, accurately position and control, and achieve precision welding of flat, curved, and complex anisotropic lights. The production process has a high degree of automation, and the plastic laser welding machine can also be embedded in the automatic production line.

During the welding process of lamps, our staff mainly adjust the angle of incidence to avoid refraction, reflection, light blocking and other phenomena to prevent energy loss. Customers require beautiful welding of lamps and ensure the firmness of lamps. Laisai laser welding technology has the advantages of beautiful welding, firmness, strong airtightness, less resin decomposition during welding, green environmental protection, and no welding debris. After the lamp welding was completed, the staff conducted a drop test. The lamp was dropped from a height of 2 meters, and the lamp was still intact. There was no crack in the welding and no deformation, which fully met the customer's welding requirements.

Compared with traditional production processes such as vibration friction welding, ultrasonic welding, and hot plate welding, laser welding not only has the same welding function, but also has the advantages of high strength, high stability, high precision, green environmental protection, no toxic odor, and no harmful noise. The lighting industry is also advancing with the times. Many companies have begun to adopt new technologies such as plastic laser welding to replace traditional production processes, which has also promoted the further development of plastic laser welding technology. As a non-contact, fast and beautiful welding method, laser welding will be the development direction of plastic welding in the future.
