Embodiment approach 1
[0055] In this embodiment, for Figure 4 and Figure 5 A method for recognizing the direction of the multilayer ceramic capacitor 1 shown will be described. First, the structure of the multilayer ceramic capacitor 1 to be identified will be described.
[0056] (Structure of Multilayer Ceramic Capacitor 1)
[0057] Such as Figure 4 and Figure 5 As shown, the multilayer ceramic capacitor 1 includes a ceramic body 10 . The ceramic body 10 is approximately rectangular parallelepiped. Specifically, the ceramic body 10 is in the shape of a regular quadrangular column. Ceramic body 10 has first and second main faces 10a, 10b, first and second side faces 10c, 10d, first and second end faces 10e, 10f (refer to Figure 5 ). The first and second main surfaces 10a, 10b extend along the longitudinal direction L and the width direction W, respectively. The first main surface 10a and the second main surface 10b are parallel to each other. The first and second side surfaces 10c an...
Embodiment approach 2
[0082] In Embodiment 1, an example of the process of measuring the magnetic flux density with respect to the multilayer ceramic capacitor 1 accommodated in the multilayer ceramic capacitor tape 2 was described. However, the present invention is not limited thereto.
[0083] For example, it is also possible to Figure 11 As shown, the laminated ceramic capacitor 1 not accommodated in the braid is conveyed by the conveying device 41 between the magnetic generating device 31 and the magnetic flux density measuring instrument 32 , and the lamination direction thereof is identified. Pass the multilayer ceramic capacitor 1 between the magnetic generator 31 and the magnetic flux density meter 32, and then rotate the multilayer ceramic capacitor 1 to align the stacking direction, or remove the multilayer ceramic capacitor 1 in an undesired stacking direction.
Embodiment approach 3
[0085] Figure 12 It is a schematic side view showing main parts of the direction recognition device for a multilayer ceramic capacitor according to the third embodiment. In this embodiment, a magnetic generation device 31 and a magnetic flux density meter 32 are provided on the transport path 42 . A plurality of laminated ceramic capacitors 1 are supplied to the transport path 42 in a row (along one direction) by a feeder such as a linear feeder. The multilayer ceramic capacitor 1 whose lamination direction is judged to be inappropriate is blown from the conveyance path 42 to the conveyance path 44 by the gas blown out from the blowing hole 43 . The multilayer ceramic capacitor 1 blown away is recovered or discarded via the transport path 44 .
[0086] The multilayer ceramic capacitor 1 transported on the transport path 42 can be housed in a braid by, for example, a braid storage machine, and can be mounted on a mounting substrate or the like by a mounting machine, for exam...
