  As shown in FIG. 4, a weight portion 302 is held by a plurality of vibration isolation plate springs 390 on the upper portion of the vibration isolation table 301. On the upper portion of the weight portion 302, the piezoelectric vibration portion 303 is held by a plurality of driving leaf springs 395. The driving leaf spring 395 is provided in a state inclined from the vertical direction.

  Also, an L-shaped elastic member 410 having a bent flat plate is provided inside the weight portion 302 and the piezoelectric vibration portion 303 in FIG. One end side of the elastic member 410 is fixed to the piezoelectric vibration portion 303, and the other end side is fixed to the weight portion 302.

  Further, piezoelectric elements 411 are disposed on both surfaces of the elastic member 410. The spring constant composed of the elastic member 410 and the piezoelectric element 411 is appropriately selected according to the condition of an arbitrary resonance frequency determined by the weight and size of the parts to be transported, the weight of the transport path 305, and the like.

  Specifically, the piezoelectric element 411 is obtained by attaching a piezoelectric ceramic having a positive polarity polarization potential on one surface of the elastic member 410 and applying a negative polarity polarization on the other surface of the elastic member 410.

  FIG. 5 is an explanatory view showing an example of the structure of the rotatable support portion 370.

  As shown in FIG. 5, the rotatable support portion 370 includes a holding portion 371 and two pinching members 375a and 375b having two kamaboko shapes.

  The holding portion 371 has a through hole formed at the center of a substantially quadrangular prism and an inner peripheral surface 372. A notch 373 is formed in a direction perpendicular to the axial direction of the through hole. Thereby, the holding | maintenance part 371 consists of a member which has a C-shaped cross section.

  Further, in the holding portion 371, a through hole 374 is formed in a portion perpendicular to the axial direction of the through hole and where the notch 373 is not formed. The through hole 374 is for fixing the elastic plate member 360 and the clamping members 375a and 375b with bolts A (see FIG. 4).

  Next, the sandwiching member 375a and the sandwiching member 375b have the same shape, and the sandwiching member 375a and the sandwiching member 375b are kamaboko-shaped members. The sandwiching member 375a and the sandwiching member 375b form a substantially cylindrical shape by attaching flat surfaces to each other.

  Further, as shown in FIG. 5, a through-hole 376 is formed in the clamping member 375a and the clamping member 375b.

  Subsequently, the flat surfaces of the clamping member 375a and the clamping member 375b are brought into contact with both surfaces of the end portion of the elastic plate member 360, respectively. Thereby, a cylindrical shape is formed at the end of the elastic plate member 360. The cylindrical shape is inserted inside the inner surface 372 of the holding portion 371. In this case, the elastic plate member 360 is located in the notch 373 and has a predetermined gap with the notch 373.

  Subsequently, the bolt A is passed through the through hole 374 of the holding portion 371, the long hole 376 of the holding member 375a, the hole of the elastic plate member 360, the long hole 376 of the holding member 375b, and the through hole 374 of the holding portion 371 in order. Thus, the holding members 375a and 375b and the elastic plate member 360 can be fixed to the holding portion 371. The adjustment of the elastic plate member 360 will be described later.

  FIG. 6 is an explanatory diagram illustrating an example of the structure of the holding unit 380.

  As shown in FIG. 6, the holding portion 380 includes a substantially L-shaped member 381. One end of the L-shaped member 381 is provided with a through hole 382 in the vertical direction and a long hole 383 in the horizontal direction.

  Then, the elastic plate member 360 can be fixed to the holding portion 380 by fixing the bolt B (see FIG. 4) through the holes of the elastic plate member 360 and the through holes 382 in this order. Further, the holding portion 380 is fixed to the piezoelectric vibrating portion 303 by inserting the bolt B through the long hole 383 of the holding portion 380 and inserting the bolt B into the hole of the piezoelectric vibrating portion 303.

  Next, FIGS. 7 and 8 are schematic views showing the relationship among the elastic plate member 360, the rotatable support portion 370, and the holding portion 380 when the elastic plate member 360 is adjusted.

  7 shows a case where the elastic plate member 360 is in a state close to a horizontal state, and FIG. 8 shows a case where the elastic plate member 360 is in the most inclined state. Here, the state close to the horizontal state indicates a case where the angle formed by the horizontal plane and the elastic plate member 360 is inclined within a range of 4 degrees or more and less than 10 degrees, and the state where the angle is most inclined is the horizontal plane and the elastic plate member 360. The case where the angle | corner which forms is inclined in the range of 10 degree | times or more and 20 degrees or less is shown.

  First, as shown in FIG. 7, one end of the elastic plate member 360 is held by the rotatable support portion 370, and the other end of the elastic plate member 360 is held by the holding portion 380.

  Then, as shown in FIG. 7, the bolt A is loosened, and the bolts C and D (see FIG. 4) are loosened. Next, the elastic plate member 360 is rotated clockwise around the one end side of the elastic plate member 360 supported by the rotatable support portion 370. Accordingly, the holding portion 380 also moves downward integrally with the other end of the elastic plate member 360. In this case, the bolt B and the bolt C move relatively upward with respect to the long hole 383 of the holding portion 380.

  Thereafter, the bolt A of the rotatable support portion 370 is tightened, and the bolts C and D are tightened. Thereby, the elastic plate member 360 can be changed from the state close to the horizontal state to the most inclined state. In order to change the elastic plate member 360 from the most inclined state to a state close to the horizontal state, the reverse procedure of the above steps may be performed.

As described above, since the elastic plate member 360 can be rotationally adjusted about the end of the elastic plate member 360 by the rotatable support portion 370 and the holding portion 380, the inclination angle of the elastic plate member 360 can be changed. In addition, the exciting force applied to the micro component 800 to be transmitted to the third conveying member 350 can be easily changed.
As a result, it is possible to reduce the number of work steps such as replacement of the component supply device 100 when it is desired to adjust the conveyance capability of the microcomponent 800. Moreover, since the conveyance capability of the micro components 800 can be adjusted, a large number of micro components 800 can be conveyed by a single component supply device 100. Therefore, it is possible to transport different microcomponents 800 using the same component supply device 100 without replacing the component supply device 100 according to the type of the microcomponent 800 to be transported. As a result, the cost for purchasing a plurality of component supply devices 100 can be reduced, and the foot space of the component supply device 100 can be reduced.

(Other examples)
FIG. 9 is an explanatory view showing another example of the structure of the rotatable support portion 370 of FIG.

  As shown in FIG. 9, the rotatable support portion 370a includes a holding portion 371a and two pinching members 375a and 375b having a semi-cylindrical shape.

  The holding portion 371a has a through hole formed at the center of a substantially quadrangular prism and an inner peripheral surface 372a. A notch 373 is formed in a direction perpendicular to the axial direction of the through hole. Further, a cut 372 b is formed on the peripheral surface of the inner peripheral surface 372 a of the through hole and on the side opposite to the notch 373. Accordingly, the holding portion 371a is made of a member having a substantially U-shaped cross section.

  In the holding portion 371a, a through hole 374a is formed in a direction perpendicular to the axial direction of the through hole and so as to penetrate the cut 372b. The through hole 374a is for fixing the elastic plate member 360 and the clamping members 375a and 375b with the bolt A.

  Next, the sandwiching member 375a and the sandwiching member 375b have the same shape, and the sandwiching member 375a and the sandwiching member 375b are kamaboko-shaped members. The sandwiching member 375a and the sandwiching member 375b form a substantially cylindrical shape by attaching flat surfaces to each other.

  Moreover, as shown in FIG. 9, the through-hole 376 is formed in the clamping member 375a and the clamping member 375b.

  Subsequently, the flat surfaces of the sandwiching member 375a and the sandwiching member 375b are brought into contact with both surfaces of the end portion of the elastic plate member 360, respectively. Thereby, a cylindrical shape is formed at the end of the elastic plate member 360. The cylindrical shape is inserted inside the inner surface 372a of the holding portion 371a. In this case, the elastic plate member 360 is located in the notch 373 and has a predetermined gap with the notch 373.

  Subsequently, the bolt A is passed through the through hole 374a of the holding portion 371a, the long hole 376 of the holding member 375a, the hole of the elastic plate member 360, the long hole 376 of the holding member 375b, and the through hole 374a of the holding portion 371 in order. By doing so, the space | interval of the notch part 372b becomes narrow, the internal peripheral surface 372a of the holding | maintenance part 371a becomes narrow, and the clamping members 375a and 375b and the elastic board member 360 can be fixed more reliably.

  In this case, since the space | interval of the internal peripheral surface 372a can be narrowed easily by using the holding | maintenance part 371a of FIG. 9, clamping member 375a, 375b and the elastic board member 360 can be fixed reliably. As a result, it is possible to prevent a decrease in the ability to fix the clamping members 375a and 375b and the elastic plate member 360 due to vibration.

  On the other hand, as shown in FIG. 10, one end of the elastic plate member 360a has a surface forming an L shape in a cross section perpendicular to the longitudinal direction of the elastic plate member 360a. A through hole is provided on the surface. The length L1 of this surface is larger than the length L2 of the substantially rectangular parallelepiped of the rotatable support portion 370b.

  Subsequently, the elastic plate member 360a is in a state close to a horizontal state by passing the bolt E (same as the bolt A) through the through-hole on the surface formed in the elastic plate member 360a and fixing it to the hole 370c of the holding portion 370b. To the most inclined state can be freely adjusted.

  In this case, by using the holding portion 370b and the elastic plate member 360a of FIG. 10, the elastic plate member 360a can be freely adjusted from the state close to the horizontal state to the most inclined state.
