[0022] Hereinafter, the electronic component conveying device of the present disclosure will be described with reference to the drawings.

[0023] Hereinafter, embodiments of the electronic component conveying device disclosed herein will be described. However, the embodiments described below are merely examples, and the present invention is not limited to the embodiments described below.

[0024] It should be noted that in this embodiment, "above" and "below" refer to the electronic component conveying device 10. Figure 1 ,as well as FIG. 2A to FIG. 2C "Above" and "below" in the case of such arrangement.

[0025] First, use Figure 5A and Figure 5BThe electronic components (hereinafter also referred to as workpieces) transported by the electronic component transport device 10 of the present disclosure will be described. Figure 5A is a side view showing an electronic component (workpiece) W, Figure 5B 1 is a front view showing an electronic component (workpiece) W.

[0026] like Figure 5A and Figure 5B As shown, the workpiece W is a capacitor having a substantially rectangular parallelepiped shape, for example, a substantially regular quadrangular prism. Specifically, the workpiece W is a regular quadrangular prism multilayer ceramic capacitor.

[0027] However, in the present embodiment, the workpiece W is not limited to a capacitor, and may be a thermistor, an inductor, or the like.

[0028] The workpiece W includes an electronic component body W1, which is also composed of a substantially regular quadrangular prism like the workpiece W. Figure 5B In the front view of the workpiece W shown, the workpiece W has a substantially square shape.

[0029] In order to obtain electrostatic capacitance, the electronic component body W1 is composed of dielectric ceramic as a main component. Specific examples of dielectric ceramics include BaTiO3, CaTiO3, SrTiO3, etc. In the electronic component body W1, according to the characteristics required by the workpiece W, auxiliary components such as Mn compounds, Mg compounds, Si compounds, Fe compounds, Cr compounds, Co compounds, Ni compounds, rare earth compounds, etc., whose content is less than that of the main component, may be appropriately added.

[0030] like Figure 5A and Figure 5B As shown, a plurality of internal electrodes W3 as internal conductors are provided inside the electronic component body W1.

[0031] The internal electrodes W3 are alternately stacked in the height direction H, and the internal electrodes W3 face each other in the height direction H with the ceramic portion W4 interposed therebetween.

[0032] Each internal electrode W3 contains a metal, in particular, a ferromagnetic metal. Specific examples of the ferromagnetic metal preferably used include Ni, Fe, and an alloy containing at least one of Ni and Fe.

[0033] Furthermore, a pair of external electrodes W2 and W2 are provided at both ends of the electronic component body W1.

[0034] The pair of external electrodes W2, W2 each contain at least one of, for example, Pt, Au, Ag, Cu, Ni, Cr, and the like.

[0035] Next, use Figure 4 An electronic component processing apparatus in which the electronic component conveying apparatus 10 of the present disclosure is incorporated will be described.

[0036] The electronic component processing device 1 includes an electronic component conveying device 10 of the present disclosure for conveying electronic components (workpieces) W, and an indexing table 40 connected to the electronic component conveying device 10 via a loading unit 42. In addition, an electronic component supply device 49 is provided upstream of the electronic component conveying device 10 for storing the workpieces W and conveying the workpieces W to the electronic component conveying device 10.

[0037] exist Figure 4 , the workpiece W is supplied from the electronic component conveying device 10 to the indexing table 40 via the loading unit 42. The workpiece W supplied to the indexing table 40 is stored in the storage groove 45 provided on the outer periphery of the indexing table 40. While the indexing table 40 is rotated, the electrical characteristics of the workpiece W in the storage groove 45 of the indexing table 40 are first measured by the electronic component measuring device 41. In the electronic component measuring device 41, a measuring probe (not shown) described later is used, and the electrical characteristics of the workpiece W are measured by bringing the measuring probe into contact with the workpiece W.

[0038] Thereafter, with the rotation of the index table 40 , the upper and lower outer surfaces of the workpiece W in the storage tank 45 are inspected using the top camera 43 and the bottom camera 44 .

[0039] Furthermore, the index table 40 rotates, and the defective workpieces W are discharged to the outside from the discharge device 46 , so that only the conforming workpieces W reach the electronic component insertion device 50 .

[0040] In the electronic component insertion apparatus 50 , after the workpiece W in the storage groove 45 of the index table 40 is sucked by an insertion nozzle (not shown), the insertion nozzle is lowered and the workpiece W sucked by the insertion nozzle is inserted into a recess 5 a of a carrier tape 5 .

[0041] After the workpiece W is placed in the recess 5a, a top tape 6 is placed on the carrier tape 5. Next, the top tape 6 is bonded to the carrier tape 5 by the soldering iron unit 53, and the recess 5a of the carrier tape 5 is sealed by the top tape 6. Thereafter, the carrier tape 5 with the recess 5a sealed by the top tape 6 is discharged to the outside.

[0042] Next, use Figures 1 to 3B as well as Figure 6 The electronic component conveying device 10 of the present disclosure incorporated in such an electronic component processing device 1 will be described.

[0043] like Figures 1 to 6As shown, the electronic component conveying device 10 conveys the workpiece W. In this case, the workpiece W is formed of a substantially regular quadrangular prism and has an axis L as described above. The electronic component conveying device 10 conveys the workpiece W along the axis L.

[0044] like Figure 1 As shown, such an electronic component conveying device 10 is composed of a device body 11 and an auxiliary component 12 mounted on the device body 11. In addition, the device body 11 and the auxiliary component 12 form an upstream side passage (hereinafter, also referred to as a first passage) 21 for conveying the workpiece W, a posture changing passage (hereinafter, also referred to as a second passage) 22 connected to the first passage 21 and rotating the workpiece W around the axis L to change the posture of the workpiece W, and a downstream side passage (hereinafter, also referred to as a third passage) 23 connected to the second passage 22 and conveying the workpiece W.

[0045] The first passage 21 conveys the workpiece W supplied from the electronic component supply device 49 to the second passage 22 , and the third passage 23 conveys the workpiece W after undergoing posture change through the second passage 22 to the index table 40 .

[0046] In addition, the workpiece W is conveyed in the electronic component conveying device 10 along the conveying direction L1 via the first passage 21 , the second passage 22 , and the third passage 23 .

[0047] In the present embodiment, the axis L of the workpiece W coincides with the conveying direction L1 of the electronic component conveying device 10 .

[0048] In addition, a pair of magnetic force generating parts 30A and 30B are provided outside the device body 11 and the auxiliary component 12, that is, outside the direction orthogonal to the conveying direction L1 and corresponding to the second passage 22, so as to clamp the device body 11 and the auxiliary component 12. Each magnetic force generating part 30A is composed of a magnet having an N pole and an S pole. The pair of magnetic force generating parts 30A and 30B will be described later.

[0049] In addition, although the example in which a pair of magnetic force generating parts 30A and 30B are provided is shown in this embodiment, for example, only one magnetic force generating part 30A may be provided.

[0050] Next, use FIG. 2A to FIG. 2C , the first passage 21 , the second passage 22 , and the third passage 23 of the electronic component conveying device 10 will be described.

[0051] First, as Figure 1 AA line cross section Figure 2AAs shown, the cross section of the first passage 21 has a V-shape 15 formed in the device body 11, and the V-shape 15 includes a pair of abutting surfaces 15a that abut against the outer surface of the workpiece W. Moreover, the V-shaped cross section 15 of the first passage 21 can accurately position and convey the workpiece W in a substantially quadrangular prism shape.

[0052] Furthermore, the first passage 21 has a relief groove 16 at the lower end of the V-shape 15 .

[0053] As described above, the workpiece W has a square shape when viewed from the front. In accordance with the square workpiece W, the angle between the pair of contact surfaces 15a, 15a of the V-shaped 15 is also 90°.

[0054] However, it is also possible that the angle between the pair of abutment surfaces 15a, 15a is not exactly 90°, depending on the forming accuracy of the first passage 21. In this case, it is also possible that a gap is generated between the outer surface of the workpiece W and the pair of abutment surfaces 15a, 15a, and the workpiece W shakes between the pair of abutment surfaces 15a, 15a.

[0055] In the present embodiment, the escape groove 16 is provided at the lower end of the first passage 21 having the V-shaped cross section 15 , so that the lower end of the workpiece W can be inserted into the escape groove 16 , thereby suppressing rattling of the workpiece W in the first passage 21 .

[0056] It should be noted that the retreat groove 16 provided at the lower end of the V-shaped 15 may also be provided at the lower end of the V-shaped 15 in a manner extending downward (see Figure 2A solid line).

[0057] Alternatively, the escape groove 16 may be provided at the lower end of the V-shaped 15 so as to extend from the abutting surface 15a on one side and extend in parallel (see Figure 2A dotted line).

[0058] Next, as Figure 1 The CC line cross-section diagram Figure 2C As shown, the cross section of the third passage 23 has a V-shape 17 formed in the device body 11, and the V-shape 17 includes a pair of abutting surfaces 17a that abut against the outer surface of the workpiece W. Moreover, the V-shaped cross section 17 of the third passage 23 can accurately position and convey the workpiece W in a substantially quadrangular prism shape.

[0059] Furthermore, the third passage 23 has a relief groove 18 at the lower end of the V-shape 17 .

[0060] As described above, the workpiece W has a square shape when viewed from the front. In accordance with the square workpiece W, the angle between the pair of contact surfaces 17a, 17a of the V-shaped 17 is also 90°.

[0061] However, it is also possible that the angle between the pair of abutment surfaces 17a, 17a is not exactly 90°, depending on the forming accuracy of the third passage 23. In this case, it is also possible that a gap is generated between the outer surface of the workpiece W and the pair of abutment surfaces 17a, 17a, and the workpiece W shakes between the pair of abutment surfaces 17a, 17a.

[0062] In this embodiment, the escape groove 18 is provided at the lower end of the third passage 23 having the V-shaped cross section 17 , so that the lower end of the workpiece W can be inserted into the escape groove 18 , thereby suppressing the rattling of the workpiece W in the third passage 23 .

[0063] It should be noted that the retreat groove 18 provided at the lower end of the V-shaped 17 may also be provided at the lower end of the V-shaped 17 in a manner extending downward (see Figure 2C solid line).

[0064] Alternatively, the escape groove 18 may be provided at the lower end of the V-shape so as to extend parallel to the contact surface 17a on one side (see Figure 2C dotted line).

[0065] Next, the second passage 22 will be described. Figure 1 BB line cross section Figure 2B As shown, the cross section of the second passage 22 has a circular portion 25 formed in the device body 11 , and the circular portion 25 has a guide surface 25 a that supports and guides the outer surface of the workpiece W when the workpiece W rotates about the axis L.

[0066] Figure 2B An imaginary circle 26 surrounding the workpiece W when the workpiece W rotates about the axis L is shown.

[0067] The imaginary circle 26 is formed by a circle having a diameter substantially equal to the length of the diagonal line L2 of the workpiece W. Specifically, the diameter of the imaginary circle 26 is slightly longer than the length of the diagonal line L2 of the workpiece W, and is the diagonal line L2×(1.05 to 1.08). In the present embodiment, the circular portion 25 of the second passage 22 extends over a range of more than 180° in the imaginary circle 26.

[0068] Next, use Figure 3A and Figure 3B The connection structure between the first passage 21 and the second passage 22 and the connection structure between the second passage 22 and the third passage 23 will be described.

[0069] First, for ease of explanation, we use Figure 3B The connection structure between the second passage 22 and the third passage 23 will be described.

[0070] like Figure 3B As shown, in the second passage 22 , the workpiece W rotates about the axis L due to the magnetic force generated by the pair of magnetic force generating portions 30A, 30B.

[0071] In this case, if the posture of the workpiece W is changed in the second passage 22 so as to completely match the V-shape 17 of the third passage 23 , the workpiece W in the second passage 22 can be smoothly transferred to the third passage 23 .

[0072] However, in reality, it is difficult to completely match the V-shape of the third passage 23 in the second passage 22 .

[0073] Therefore, in the present embodiment, at the second passage side end portion 23A of the third passage 23, the V-shape of the third passage 23 has a V-shape 17A formed by a tangent line of the circular portion 25 of the second passage 22 (see Figure 3B solid line).

[0074] Moreover, if Figure 1 As shown, the V-shaped third passage 23 gradually rises from the starting end 23B1 of the transition region 23B, i.e., the second passage side end 23A, toward the downstream side in the transition region 23B of the third passage 23, and has a V-shaped shape 17B (see FIG. 17B ) on the extension line of the lower end of the circular portion 25 of the second passage 22 at the end 23B2 of the transition region 23B. Figure 3B dotted line).

[0075] Thus, in the third passage 23, the V-shape gradually rises toward the upstream side from the V-shape 17A at the start end of the transition region 23B, that is, the second passage side end 23A, and changes to the V-shape 17B at the end end 23B2 of the transition region 23B, where the lower end of the V-shape reaches the extension line of the lower end of the circular portion 25 of the second passage 22. Thus, the workpiece W that has been rotated around the axis L in the second passage 22 and whose posture has been changed can be smoothly conveyed into the third passage 23 without contacting the wall surface 27 of the third passage 23 that forms the V-shape. Furthermore, by gradually raising the workpiece W in the third passage 23, the workpiece W can be returned to the height of the existing equipment.

[0076] In the present embodiment, in the transition region 23B of the third passage 23 , the V-shape 17A is gradually raised to the V-shape 17B to perform height adjustment.

[0077] Next, use Figure 3AThe connection structure between the first passage 21 and the second passage 22 will be described.

[0078] like Figure 3A As shown, in the second passage 22 , the workpiece W is rotated about the axis L by the magnetic force generated by the pair of magnetic force generating portions 30A, 30B.

[0079] In this embodiment, the V-shaped first passage 21 has a V-shaped shape 15A formed by a tangent line of the circular portion 25 of the second passage 22 at the starting end 21B1 of the transition region 21B (see Figure 3A dotted line).

[0080] Moreover, if Figure 1 As shown, the V-shaped first passage 21 gradually rises from the starting end 21B1 of the transition region 21B toward the downstream side in the transition region 21B of the first passage 21, and has a V-shaped shape 15B (refer to FIG. 15B ) whose lower end is consistent with the lower end of the circular portion 25 of the second passage 22 at the end 21B2 of the transition region 21B of the first passage 21, i.e., the second passage side end 21A. Figure 3A solid line).

[0081] Thus, in the first passage 21, the V-shape gradually rises from the V-shape 15A at the starting end 21B1 of the transition area 21B of the first passage 21 toward the upstream side, and changes to the V-shape 15B whose lower end coincides with the lower end of the circular portion 25 of the second passage 22 at the end 21B2 of the transition area 21B, i.e., the second passage side end 21A. Thus, the workpiece W positioned in the rotation direction by the V-shape of the first passage 21 can be accurately conveyed into the second passage 22. Furthermore, by gradually raising the workpiece W in the first passage 21, the workpiece W can be conveyed into the second passage 22 using the height of the existing equipment.

[0082] In the present embodiment, in the transition region 21B of the first passage 21 , the V-shape 15A is gradually raised to the V-shape 15B to perform height adjustment.

[0083] Next, the operation of this embodiment having such a structure will be described.

[0084] First, the workpiece W is supplied from the electronic component supply device 49 , and the workpiece W supplied from the electronic component supply device 49 is conveyed while being vibrated by the electronic component conveying device 10 . Thereafter, the workpiece W conveyed by the electronic component conveying device 10 is conveyed to the indexing table 40 .

[0085] During this time, the workpiece W conveyed into the electronic component conveying device 10 is conveyed while being accurately positioned in the rotation direction by the V-shaped shape 15 of the first passage 21 , and enters the second passage 22 through the transition area 21B of the first passage 21 .

[0086] At this time, at the second passage side end portion 21A of the first passage 21, since the lower end of the V-shaped portion 15 coincides with the lower end of the circular portion 25 of the second passage 22, the workpiece W positioned in the rotation direction by the V-shaped portion 15 of the first passage 21 can be smoothly guided into the second passage 22 (see Figure 3A ).

[0087] The workpiece W has an internal electrode W3 having ferromagnetism. Therefore, the workpiece W in the second passage 22 changes its posture so that the surface direction of the internal electrode W3 coincides with the direction of the magnetic force lines 35 generated by the pair of magnetic force generating parts 30A and 30B.

[0088] For example, in Figure 6 In the case where the surface of the internal electrode W3 of the workpiece W in the second passage 22 faces the horizontal direction, the workpiece W is rotated about the axis L by the magnetic force generated by the pair of magnetic force generating parts 30A and 30B. At this time, the workpiece W is guided by the guide surface 25a of the circular portion 25 of the second passage 22 and rotated 90°, and the surface of the internal electrode W3 is aligned with the direction of the magnetic force line 35, that is, the surface of the internal electrode W3 facing the horizontal direction is rotated as shown in FIG. Figure 6 Change its posture in the vertical direction as shown.

[0089] On the other hand, Figure 6 In the case where the surface of the internal electrode W3 of the workpiece W is previously aligned with the direction of the magnetic field lines 35, that is, the surface of the internal electrode W3 is as shown in FIG. Figure 6 When the workpiece W is oriented in the vertical direction as shown, the workpiece W in the second passage is not rotated about the axis L but is directly conveyed to the third passage 23 .

[0090] In this case, at the second passage side end portion 23A of the third passage 23, the V-shape of the third passage 23 has a V-shape 17A formed by a tangent line of the circular portion 25 of the second passage 22 (see Figure 3B The V-shaped portion of the third passage 23 gradually rises toward the downstream side in the transition region 23B of the third passage 23, and at the end 23B2 of the transition region 23B, the lower end of the V-shaped portion reaches the V-shaped portion 17B on the extension line of the lower end of the circular portion 25 of the second passage 22 (see Figure 3B dotted line).

[0091] Therefore, the workpiece W in the second passage 22 can be smoothly conveyed into the third passage 23 without contacting the V-shaped wall surface 27 of the third passage 23. Thereafter, the workpiece W is gradually raised in the third passage 23, so that the workpiece W can be returned to the height of the existing equipment.

[0092] Furthermore, after the workpiece W is rotated about the axis L in the second passage 22 to change its posture, the workpiece W can be conveyed to the third passage 23 , and the workpiece W can be reliably positioned in the rotation direction by the V-shaped cross-section 17 of the third passage 23 .

[0093] As described above, according to the present embodiment, the workpiece W can be accurately positioned in the rotation direction around the axis L in the first passage 21 of the electronic component conveying device 10 by the V-shaped cross-section 15, and the workpiece W accurately positioned by the V-shaped cross-section 15 of the first passage 21 can be reliably conveyed into the second passage 22.

[0094] In addition, in the second passage 22, the workpiece W changes its posture by rotating around the axis L in such a way that the surface direction of its internal electrode W3 is consistent with the direction of the magnetic lines of force 35 generated by a pair of magnetic force generating parts 30A and 30B, so that the postures of all the workpieces W in the second passage 22 can be consistent in such a way that they are oriented in a certain direction.

[0095] Thus, the workpiece W rotated about the axis L in the second passage 22 and changed in posture and in the same posture is conveyed to the third passage 23. The workpiece W can be accurately positioned in the rotation direction about the axis L by the V-shaped shape 17 of the third passage 23.

[0096] Therefore, compared with the case where the workpiece W is rotated by the second passage 22 including the circular portion 25 and then the rotated workpiece W is conveyed by the second passage 22 including the circular portion 25, the workpiece W whose posture is changed in the rotation direction by the second passage 22 can be accurately positioned in the rotation direction by the V-shaped shape 17 of the third passage. Therefore, the workpiece W rotated by the second passage 22 can be conveyed by the third passage 23 while maintaining its posture.

[0097] In addition, at the second passage side end portion 23A of the third passage 23, the V-shape of the third passage 23 has a V-shape 17A formed by a tangent line of the circular portion 25 of the second passage 22. Therefore, the workpiece W in the second passage 22 can be smoothly conveyed into the third passage 23 without contacting the wall surface 27 of the third passage 23 that forms the V-shape 17.

[0098] Furthermore, by providing the escape groove 16 at the lower end of the V-shaped portion 15 of the first passage 21, the lower end of the workpiece W can be inserted into the escape groove 16. Thus, rattling of the workpiece W in the first passage 21 can be suppressed.

[0099] Furthermore, by providing the escape groove 18 at the lower end of the V-shaped portion 17 of the third passage 23, the lower end of the workpiece W can be inserted into the escape groove 18. Thus, rattling of the workpiece W in the third passage 23 can be suppressed.
