  • Patent number: 11022420
    Abstract: A flatness sensing device includes a pressure sensing unit and a controller. The pressure sensing unit includes a plate portion, and a pressure sensor fixed and exposed at an edge of the plate portion. A sensing surface of the pressure sensor is flush with the bottom surface of the plate portion. The pressure sensor senses a pressure or lack of pressure of an object to be tested when it touches the object to be tested. The controller receives the pressure value output from the pressure sensor and determines a flatness of the object to be tested, the controller can issue an alarm on finding non-flatness and cause the degree of flatness to be displayed to a user.

  • Publication number: 20210116967
    Abstract: A transparent display device includes a flexible circuit board, a plurality of lamps, and a plurality of IC components. The flexible circuit board includes lamp fixing portions, a first bending portion, and second bending portions. The lamp fixing portions are spaced apart from each other and arranged in X-axis columns. Each lamp fixing portion extends as a strip along a Y axis. The X axis is perpendicular to the Y axis. Each lamp fixing portion includes an X-axis end edge and a Y-axis side edge. The first bending portion is bent from the end edge of each lamp fixing portion. Each second bending portion is bent from the side edge of one lamp fixing portion.

  • Publication number: 20200298434
    Abstract: A cutting device configured to cut a workpiece includes a base and a cover plate. The cover plate includes a base plate, a pressing member, and an elastic member. A surface of the base plate facing the base defines a receiving groove configured to receive the pressing member. The pressing member defines a number of first cutter slots to allow cutters to pass through to cut the workpiece located between the base and the cover plate. The elastic member includes a connecting portion and an elastic portion. The connecting portion is fixedly coupled to the pressing member and partially extends beyond an edge of the pressing portion. One end of the elastic portion abuts against the base plate, and a second end of the elastic portion is coupled to the connecting portion.

  • Patent number: 10706531
    Abstract: A method for checking the proper dispensation of glue onto a circuit board in manufacture includes the use of fluorescent materials in such glue, activating a light source to illuminate a circuit board when the circuit board is placed on an electronic device, and controlling an image capturing device to capture an image of the circuit board. The image captured by the capturing device is compared with a standard stored image of the circuit board, and a determination is made as to whether the circuit board passes test according to the comparison.
