Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a carrier lifting device. Background Art

[0002] With the development of automated production, transportation, lifting and other processes in industrial production are gradually being replaced by automated machinery. For example, during the production process of semiconductor products, it is necessary to lift the carrier containing semiconductor materials to a preset height for further processing and production. Most of the existing devices for lifting carriers directly lift the carrier from the bottom and then slowly rise. However, the carrier and the products in the carrier themselves have a certain height. The existing lifting device only fixes the bottom of the carrier. During the lifting process, the carrier will inevitably shake, which is not conducive to the positioning of the next step of processing. In addition, in order to avoid the shaking of the carrier as much as possible, the lifting speed of the existing lifting device is also limited. Utility Model Content
