  • Publication number: 20150029330
    Abstract: In a control unit of an electronic component mounting apparatus, when an imaging form of a component imaging unit is set to a first mode, a component recognition unit recognizes a first electronic component based on an imaged image due to a first imaging element of the component imaging unit, and recognizes a second electronic component based on an imaged image due to a second imaging element of the component imaging unit. Meanwhile, when the imaging form is set to a second mode, the component recognition unit recognizes the electronic components based on an image in which the imaged image by the first imaging element is combined with the imaged image by the second imaging element.

  • Patent number: 7843573
    Abstract: A method for profiling the shape of a component using a line sensor (110) which is provided in a component mounter (100) and which profiles the shape of the component (200) three-dimensionally by (a) projecting a sweeping light onto the component (200) in a relative movement between the line sensor (110) and the component (200) held by a mounting head (103) so that the sweeping light traverses the direction of the movement and (b) detecting the reflected light from the component using a detector (119). The method includes getting the component (200) from the component supply unit 101 using the mounting head (103), rotating the component (200) by a predetermined angle within a predetermined surface, and profiling the shape of the rotated component using the line sensor (110).

  • Patent number: 7502170
    Abstract: An illumination apparatus includes a through-hole for detection formed at a center portion, and irradiates diffused light and directional light to an object to be detected. The apparatus includes an annular diffusion plate which diffuses light, a light source disposed annularly, and an annular reflection plate which reflects light from the light source to the side of said object to be detected. The diffusion plate, light source, and reflection plate are disposed in the order from the side of said object to be detected. The diffused light is generated by irradiating light from said light source to the object to be detected through said diffusion plate. Light from said light source is reflected by said reflection plate and then irradiated to the object to be detected.

  • Patent number: 7299539
    Abstract: An apparatus has a holder that receives a component from a component supply and then places the component on a substrate. In operation, it is determined whether the holder would make an interference with another component already mounted on the substrate. If this judgement is affirmative, mounting of the component held by the holder is prohibited. If, on the other hand, this judgement is negative, the component held by the holder is mounted onto the substrate.

  • Patent number: 5912985
    Abstract: When an image of an object is recognized, a template having a size smaller than the object is used. First, operation reference points C.sub.s (X.sub.m, Y.sub.n) are set at steps smaller than lengths along the X and Y directions of an image of an object to be recognized, and a template T(x.sub.i, y.sub.i) is set at the operation reference points C.sub.s (X.sub.m, Y.sub.n). Then, an equation, ##EQU1## is operated based on the template T(x.sub.i, y.sub.i) and the image data P(X, Y). Next, candidate points are determined as points having M(X.sub.m, Y.sub.n) larger than a reference value. Then, a position of the image of the object is determined according to the candidate points. Even if an image to be recognized is inclined, the position and the slope of the image can be detected at a fast speed even for image data with noise.

  • Patent number: 5832105
    Abstract: In a component detecting method and apparatus, intensity data stored in an intensity data storing device are rearranged in order of increasing intensity data. An intensity data quadratic differential table is formed by quadratically differentiating the intensity data of an intensity profile with respect to a data number of the intensity data. The data number at a zero-crossing point at which a quadratic differential data obtained by quadratically differentiating the intensity data is changed between positive and negative through zero from the intensity data quadratic differential table is detected. A threshold value is determined according to the intensity data of the intensity profile corresponding to the data number at the zero-crossing point.
