Summary of the Invention
Problems to be Solved by the Invention
[0004] When manufacturing the above-described electronic component, a large number of chip components are automatically transported by a machine. In this case, a large number of chip components are aligned and held by vacuum suction and transported. In a configuration where the pair of external electrodes is provided on the bottom surface of the body, when an outer surface different from the bottom surface provided with the external electrodes is vacuum-sucked, the force adsorbed on the adsorption surface by vacuum suction increases. As a result, the frictional force caused by vacuum suction increases, and there is a risk that the transportation of the chip component stops due to the frictional force. Therefore, there is a risk that the production throughput decreases.
[0005] One aspect of the present invention aims to provide an electronic component configured to facilitate the transportation of chip components.
Means for Solving the Problems
[0006] An electronic component according to one aspect of the present invention includes a body, an internal conductor, and a pair of external electrodes. The body has a first surface and at least one second surface. The internal conductor is provided inside the body. The pair of external electrodes is provided on the first surface. In this electronic component, a concavo-convex portion is provided. The first surface and the second surface intersect or face each other. The concavo-convex portion forms a groove extending in a direction along the first surface and includes the second surface.
[0007] In this electronic component, a concavo-convex portion is provided, and the concavo-convex portion forms a groove extending in a direction along the first surface on which the pair of external electrodes is provided. In this case, even if the second surface side different from the first surface on which the external electrodes are provided is vacuum-sucked, the force adsorbed on the adsorption surface by the vacuum suction can be suppressed. Further, when the chip component forming the electronic component moves along the groove, the chip component can move smoothly with respect to the adsorption surface. As a result, the chip component can be easily transported.
[0008] In the above aspect, the length of the body in the first direction may be larger than the length of the body in the second direction and the length of the body in the third direction. The first direction is along the first surface and the second surface. The second direction is orthogonal to the first surface. The third direction is orthogonal to the first direction and the second direction. The groove may extend in the first direction. In this case, when the chip component forming the electronic component moves in the longitudinal direction of the body, the chip component can move more smoothly with respect to the adsorption surface. As a result, the chip component can be transported more easily.
[0009] In the above aspect, the first surface and the second surface may extend in a direction intersecting each other. In this case, when the chip component is transported, even if it is vacuum-sucked on the surface side adjacent to the pair of external electrodes, the chip component can be easily transported.
[0010] In one of the above aspects, the first surface and the second surface may face each other. In this case, even if the chip component is vacuum-sucked on the side opposite to the surface provided with the pair of external electrodes during the conveyance of the chip component, the chip component can be easily conveyed.
[0011] In one of the above aspects, the concavo-convex portion may include a first portion and a second portion. The first portion may be formed of a material different from that of the base body. The second portion may be formed by the base body. The first portion and the second portion may be alternately arranged in a direction intersecting the first surface. In this case, the groove extending in the direction along the first surface can be formed more easily and reliably by the concavo-convex portion.
[0012] In one of the above aspects, the first portion may be formed of a metal material. In this case, the strength can be ensured and it can be easily configured.
Advantages of the Invention
[0013] One aspect of the present invention provides an electronic component in which the conveyance of a chip component is easily configured.

[0068] Next, the operation and effects of electronic components 1, 1A, 1B in this embodiment and the modified example will be described.
[0069] FIG. 12(a) and FIG. 12(b) are conceptual diagrams showing a state in which a chip component of a comparative example is being transported by vacuum suction. The chip component 201 includes a body having side surfaces 202c, 202e, 202g, 202h and external electrodes 210. The external electrode 210 is provided on the side surface 202h. External electrodes are not provided on the side surfaces 202c, 202e, 202g, and they exhibit a planar shape. The suction surface 301 sucks an electronic component by vacuum suction for transportation.
[0070] In FIG. 12(a), the chip component 201 is being adsorbed onto the suction surface 301 in the direction α on the side surface 202h side where the external electrode 210 is provided. In this case, a gap is secured between the side surface 202h and the suction surface 301, and the force by which it is adsorbed onto the suction surface by vacuum suction becomes a value within an appropriate range. As a result, the chip component can be appropriately transported in the direction along the side surfaces 202c, 202e, 202g, 202h.
[0071] In FIG. 12(b), the chip component 201 is being adsorbed onto the suction surface 301 in the direction α on the side surface 202c. In this case, the side surface 202c is in close contact with the suction surface 301, and the force by which it is adsorbed onto the suction surface by vacuum suction increases. The frictional force due to vacuum suction increases, and there is a possibility that the transportation of the chip component may stop due to the frictional force.
[0072] In the electronic component 1, uneven portions 45, 55, 65 are provided, and the uneven portions 45, 55, 65 form grooves extending in the X-axis direction along the side surface 2h where a pair of external electrodes 10, 20 are provided. In this case, even if the surface side different from the side surface 2h where the external electrodes 10, 20 are provided is vacuum-sucked, the force by which it is adsorbed onto the suction surface by vacuum suction can be suppressed. Furthermore, when the chip component forming the electronic component 1 moves along the groove, the frictional force can be reduced. As a result, the chip component can be transported smoothly. The electronic component 1A and the electronic component 1B also have the same configuration and exhibit the same operational effects.
[0073] For example, in the example shown in FIG. 13, the chip component of the electronic component 1 is adsorbed on the adsorption surface 301 in the direction α on the side surfaces 2c and 2d. In this case, since the grooves V4 and V5 are formed by the guides 61, 62, and 63, a gap is secured between the side surfaces 2c and 2d and the adsorption surface 301, and the force adsorbed on the adsorption surface by vacuum adsorption becomes a value within an appropriate range. As a result, the chip component can be appropriately conveyed in the X-axis direction along the side surface 2h. Further, since the uneven portion 65 extends in the X-axis direction, when the chip component is conveyed in the X-axis direction, the chip component can smoothly move with respect to the adsorption surface. For example, when the chip component moves along the extending direction of the uneven portion 65, the change in the frictional force generated between the adsorption surface 301 and the electronic component during the conveyance of the chip component is suppressed. When adsorbed on the adsorption surface 301 in the direction α on the side surface 2g side, a gap is secured by the uneven portion 45, and when adsorbed on the adsorption surface 301 in the direction α on the side surfaces 2e and 2f side, a gap is secured by the uneven portion 55.
[0074] In the example shown in FIG. 14, the chip component of the electronic component 1B is adsorbed on the adsorption surface 301 in the direction α on the side surfaces 2c and 2d. In this case, since the grooves V24 and V25 are formed by the ribs 101, 102, 103 and the covers 73, 74, a gap is secured between the side surfaces 2c and 2d and the adsorption surface 301, and the force adsorbed on the adsorption surface by vacuum adsorption becomes a value within an appropriate range. As a result, the chip component can be appropriately conveyed in the X-axis direction along the side surface 2h. Further, since the uneven portion 105 extends in the X-axis direction, when the chip component is conveyed in the X-axis direction, the chip component can smoothly move with respect to the adsorption surface. For example, when the chip component moves along the extending direction of the uneven portion 105, the change in the frictional force generated between the adsorption surface 301 and the electronic component during the conveyance of the chip component is suppressed. When adsorbed on the adsorption surface 301 in the direction α on the side surface 2g side, a gap is secured by the uneven portion 85, and when adsorbed on the adsorption surface 301 in the direction α on the side surfaces 2e and 2f side, a gap is secured by the uneven portion 95.
[0075] In the example shown in this embodiment, the length of the base body 2 in the X-axis direction is greater than the length of the base body 2 in the Y-axis direction and the length of the base body 2 in the Z-axis direction. The X-axis direction is along the side surfaces 2h and 2c, 2d, 2e, 2f, 2g. The Y-axis direction is orthogonal to the side surface 2h. The Z-axis direction is orthogonal to the X-axis direction and the Y-axis direction. The grooves V1, V2, V3, V4, V5 extend in the X-axis direction. In this case, when the chip component forming the electronic component 1 moves in the longitudinal direction of the base body, the frictional force can be reduced. As a result, the chip component can be conveyed more easily. The electronic components 1A, 1B in the modified examples also have the same configuration and exhibit the same operational effects.
[0076] In the example shown in this embodiment, the side surface 2h and the side surfaces 2c, 2d, 2e, 2f extend in directions intersecting with each other. In this case, even if vacuum suction is performed on the surface side adjacent to the pair of external electrodes 10, 20 during the conveyance of the chip component, the chip component can be easily conveyed. The electronic components 1A, 1B in the modified examples also have the same configuration and exhibit the same operational effects.
[0077] In the example shown in this embodiment, the side surface 2h and the side surface 2g face each other. In this case, even if vacuum suction is performed on the side opposite to the side surface 2h provided with the pair of external electrodes 10, 20 during the conveyance of the chip component, the chip component can be easily conveyed. The electronic components 1A, 1B in the modified examples also have the same configuration and exhibit the same operational effects.
[0078] In the example shown in this embodiment, the uneven portions 55, 65 include a first portion and a second portion. The first portion is formed of a material different from that of the base body 2. The second portion is formed by the base body 2. The first portion and the second portion are alternately arranged in a direction intersecting the side surface 2h. In this case, the grooves V2, V3, V4, V5 extending in the direction along the side surface 2h can be formed more easily and surely by the uneven portions 55, 65. The first portion is formed of a metal material. In this case, strength can be ensured and it can be easily configured. The electronic components 1A, 1B in the modified examples also have the same configuration and exhibit the same operational effects.
