  • Patent number: 11608205
    Abstract: A head of a tag device having a body, at least one row of negative-pressure through holes and at least one row of positive-pressure through holes. The body has a first surface and a second surface. The rows of negative and positive-pressure through holes are formed through the first and second surfaces of the body and arranged along a long-axis direction. Two negative and positive-pressure through holes at both ends of the corresponding row of negative and positive-pressure through holes are respectively close to the short sides of the body. Therefore, an effective labeling area is distributed between two short sides. The head of the tag device of the present invention provides a stable labeling operation for different products where different components are mounted and increases units per hour (UPH).

  • Publication number: 20220128623
    Abstract: A device for Over-the-Air testing includes a carrier unit, an automatic positioning member and a housing unit. The automatic positioning member is adapted to convey an object under test to an electrical connection zone of the carrier. The housing unit includes a housing shell, a pressing plate and a receiver. The housing shell defines a testing space that has an open end where the pressing plate is disposed. The housing unit and the carrier unit are movable relative to each other. When the carrier unit abuts the housing unit, the object under test is exposed to the testing space and is pressed against the electrical connection zone by the pressing plate so that electromagnetic waves from the object under test are received by the receiver.

  • Publication number: 20220097891
    Abstract: A manual labeling device is disclosed. The manual labeling device has a platform, a plurality of positioning elements and a pivoting device. The platform has a labeling area. The positioning elements are mounted on the platform and around the labeling area. The pivoting device is pivotally mounted on one side of the platform and has a pivot shaft and a pivot arm. The operator manually places one product in the labeling area of the platform and the product is fixed in the labeling area by the positioning elements. The operator only pivots the pivot arm and the pivot arm directly aligns with the labeling area. Therefore, it does not take times to align the tool and the labeling area before attaching the label and the label attaching task is simplified to increase the productivity and quality of labeling (units per hour; UPH).

  • Patent number: 11164771
    Abstract: A wafer transferring device adapted to suck and transfer a first wafer is provided. The wafer transferring device includes an arm and a supporting carrier. The supporting carrier is connected to the arm. The supporting carrier has a single vacuum suction port exposed to an upper surface of the supporting carrier. The supporting carrier is adapted to move to a position below the first wafer. The single vacuum suction port is adapted to suck a first central region of the first wafer so as to lift up and transfer the first wafer.
