Description

[Technical Field]

[0001] The present invention relates to a lifting system, and more particularly to a lifting system having a function of positioning and lifting a workpiece to be machined. [Background technology]

[0002] Currently, raised floor systems are widely used in electrostatic-protected computer rooms and clean rooms in semiconductor factories. During the conventional aluminum alloy die-casting process, many burrs are generated on the surface of the ejector pins of the raised floor. These burrs cause problems during the installation process, such as poor adhesion between the raised floor and the substrate, making it unsuitable for installation by workers and raising safety concerns.

[0003] In conventional technology, detailed processing of each surface of the raised floor after molding is mainly done manually, requiring workers to transport the raised floor in bulk to the corresponding processing location and perform the processing work. This not only makes the production process discontinuous and inefficient, but also requires a great deal of labor and time to be wasted on each processing.

However, the positioning of the various processing stations of the raised-floor production line is not very accurate, and there are still problems with precision and yield.
