  • Patent number: 11119001
    Abstract: A machine tool health monitoring method which is to use a predetermined plurality of vibration sensors on a plurality of components of a machine tool and to drive motors of the machine tool to excite the machine tool using an electronic device while the health status of the machine tool is good, and then to perform a diagnostic process to obtain a characteristic cluster consisting of a plurality of modals, and then to define the characteristic cluster as a sample health characteristic cluster. The diagnostic process includes the procedures of vibration transmissibility obtaining, singular value decomposition, curve fitting and modal establishing. In addition, excite the machine tool and proceed the diagnosis process to obtain a current health characteristic cluster. Finally, the current health characteristic cluster is compared with the sample health characteristic cluster to judge whether the machine tool is healthy or not.

  • Patent number: 10675655
    Abstract: The present disclosure provides a device and method for powder distribution and an additive manufacturing method, wherein different size or kind of powders could be chosen to be accommodated within a receptacle. The receptacle can uniformly mix the powder by a rotation movement, pour out the powders by the rotation movement and distribute the powders for forming a layer by a translation movement. In another embodiment, the receptacle further comprises a heating element for preheating the powders. Not only can the present disclosure uniformly mix the powders so as to reduce the thermal deformation and distribute the powder layer compactly, but also can the present disclosure distribute different kinds of powder in different layer so as to increase the diversity in additive manufacturing.

  • Patent number: 7040524
    Abstract: An automatic packaging method of optical elements includes a focusing platform set, a Z-axis feeder set and an automatic feeding set. The Z-axis feeder set is provided above the focusing platform set. An automatic feeding set is arranged on a horizontal plane between the Z-axis feeder set and the focusing platform set by an appropriate distance. An upper part and a lower part of an optical element are supported by the lower end of the Z-axis feeder set and the upper end of the focusing platform set, respectively. The lower end of the Z-axis feeder set is adjusted vertically and horizontally with respect to the focusing platform set such that the upper part and the lower part are arranged in a line and coincide with each other. Afterward, by using the automatic feeding set, the upper part and the lower part of the optical element are bound together via the solders.
