Robots are used for transporting goods and are essential equipment for intelligent warehousing. Existing robots generally use adsorption devices to fix goods that need to be transported. There are two types of adsorption devices: one uses a vacuum generator, and the other uses a vacuum pump. The vacuum pump plays an important role in the adsorption device, as it is responsible for creating and maintaining the necessary vacuum environment to ensure that the adsorption process can be effectively carried out.
