As a high-precision and high-efficiency welding method, laser welding has completely changed the manufacturing industry. It can achieve fast and high-quality welding, efficiently connect complex components in different industries, improve production efficiency, reduce scrap rate, and thus reduce production costs.
At the same time, laser welding can also be applied to various materials and complex structures, so it has been widely used in fields such as automobiles, aerospace electronics, medical equipment, and the growing battery and electric vehicle industries.
In practical applications, in order to achieve top-level welding, in addition to the excellent performance of the laser, the precision of the fixture design is also crucial. A fixture is a device used to fix the processing object during the manufacturing process, designed to ensure that the workpiece is in the correct position for processing or inspection. It is usually composed of positioning elements, clamping devices, tool guide elements, indexing devices, connecting elements, and fixture bodies.
The fixture design not only provides stable support for the workpiece during laser welding, ensuring centering and positioning during welding, but also reduces deformation and residual stress, further improving welding quality. The accuracy and stability of the fixture directly affect the accuracy and consistency of welding, and is one of the key factors in achieving high-quality and efficient welding. Therefore, for the manufacturing industry, fixture design is a very important technology that needs to be fully valued and carefully designed.
Today, let's take a deep look at the mystery and importance of fixture design. Fixture design must address five basic functions to ensure that laser welding can unleash its full potential in applications, namely: easy loading and unloading, close contact between parts, consistent registration and tolerance, unobstructed sight, and camera alignment inspection.
Once these five functions cannot be guaranteed, it may lead to reduced welding quality, reduced device life, and production line obstruction.
Easy loading and unloading (loading/unloading)
In today's fast-paced manufacturing environment, efficiency is the core competitiveness of enterprises. Therefore, the fixture must facilitate the smooth loading and unloading of the parts to be welded, which is particularly important for industries such as medical devices, automobiles, aerospace, and electric vehicles, because these industries have extremely high requirements for accuracy and speed.
If the fixture is not designed properly, it will be inconvenient to place and remove parts, which will directly affect production efficiency. Especially when the fixture is used as a carrier tool, the components are pre-loaded into the fixture and then transferred to the laser system for welding. This design can further improve production efficiency and reduce manual intervention and operation time.
