However, in the above-described conventional transfer device, one of the vibration motor and the swing motor (one motor) needs not only the capacity to move the weight of the tray holder, but also the capacity to move the extra weight of the other motor. Therefore, there is a problem that an increase in the size of the transfer device accompanying an increase in the size of one motor cannot be avoided. Moreover, since the power consumption required for the operation of the transfer device is increased, there is a problem that the running cost of the transfer device is increased.
In addition, if one motor vibrates or swings with the tray, a load is applied to the power cable or control cable of one motor based on these movements. There is also a problem that it is necessary to carry out and the handling of the transfer device becomes troublesome.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a transfer device that can be reduced in size and running cost and can be easily maintained.

In order to solve this problem, a transfer device according to the present invention is a transfer device that imparts a vibrating motion and a swinging motion to a tray that can accommodate a large number of chip components. A holding unit mounting base mounted on the base so as to be swingable about a rotation axis, and the holding unit so as to be movable in a direction along the rotation axis with respect to the holding unit mounting base A tray holding unit that is mounted on the mounting table and detachably holds the tray, a swinging motor that swings the holding unit mounting table and the tray holding unit with respect to the base, and the tray holding unit And a vibration motor that vibrates in a direction along the rotation axis with respect to the holding unit mounting table, the oscillation motor and the oscillation motor being fixed to the base, and an output of the oscillation motor The axis is in the direction of the axis of rotation And the output shaft of the vibration motor extends from the base side toward the tray holding portion and is inserted through an insertion hole formed in the holding portion mounting table. The tip of the output shaft of the vibration motor is inserted into an inner hole formed in the tray holding portion, and the rotation of the output shaft of the vibration motor is converted into vibration in a direction along the rotation axis. The insertion hole and the inner hole are connected to the tray holding part via a vibration transmission mechanism that transmits the insertion part and the inner hole when the holding part mounting table and the tray holding part swing. And the vibration conversion mechanism is fixed to the front end of the output shaft of the vibration motor so that a gap between the rotation shaft and the output shaft of the vibration motor is maintained. The eccentric roller and the tray A pair of receiving members that are provided in an inner hole of the holding unit and sandwich the eccentric roller, and the pair of receiving members are configured to move the eccentric roller when the holding unit mounting table and the tray holding unit swing. It is characterized by being held in a sandwiched state .

According to this transfer device, the holding unit mounting table and the output shaft of the vibration motor do not interfere with each other regardless of the swinging movement of the holding unit mounting table and the tray holding unit by the swing motor, and the vibration transmission mechanism. Thus, the rotation of the output shaft of the vibration motor is converted into the vibration of the tray holding portion. That is, the vibration motion of the tray holding portion by the vibration motor is not hindered by the swinging motion of the holding portion mounting table and the tray holding portion.
Since the swing motor and the vibration motor are fixed to the base, it is possible to prevent one of the swing motor and the vibration motor from vibrating or swinging together with the tray holding portion as in the prior art.

Therefore, the swing motor and the vibration motor do not require an extra capacity as in the prior art, so that the swing motor and the vibration motor can be prevented from being enlarged, and the transfer device can be downsized. Furthermore, since the power consumption required for the operation of the transfer device is reduced, the running cost of the transfer device can be kept low.
In addition, since the swing motor and the vibration motor are fixed to the base, no load is applied to the power cable and the control cable of the swing motor and the vibration motor. Inspection can be carried out with a long cycle, that is, the transfer device can be handled easily.

According to the present invention, one of the swinging motor and the vibrating motor does not vibrate or swing with the tray holding portion by the other motor, so that the size of the other motor can be prevented and the transfer device can be downsized. As well as low running costs.
Further, since it is possible to prevent vibrations and swinging loads from being applied to the swing motor and the power cable and control cable of the swing motor, the transfer device can be handled easily.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the transfer device 1 according to this embodiment imparts a vibrating motion and a swinging motion to the tray T that can accommodate a large number of chip components. The holding unit mounting table 5 and the tray holding unit 7 are arranged in order, and the swing motor 9 and the vibration motor 11 are fixed to the base 3. For example, as shown in FIG. 3, the tray T is configured by forming a large number of insertion holes T <b> 2 that are opened on the upper surface T <b> 1 and individually accommodate a large number of chip components.

As shown in FIGS. 1 and 2, the holding unit mounting table 5 is attached to the base 3 so as to be swingable in the AB direction about the first rotation axis O <b> 1. On the other hand, the swing motor 9 is fixed to the upper surface 3 a of the base 3, and its output shaft 13 is formed to extend in the direction of the first rotation axis O <b> 1 and is connected to the holding unit mounting base 5. As a result, the holding unit mounting table 5 is driven to swing as the output shaft 13 of the swinging motor 9 rotates about the first rotation axis O1.
The output shaft 13 of the swinging motor 9 is provided with a position detecting means 15 for detecting the rotational position. By this position detecting means 15, the range of the rotation angle of the output shaft 13, that is, the holding portion mounting. A swing angle range of the mounting table 5 is defined. Further, based on the detection result of the position detection means 15, drive control of the swing motor 9 is performed.

  The tray holding unit 7 holds the tray T in a detachable manner, and is mounted on the holding unit mounting table 5 via a slide mechanism 17. The slide mechanism 17 is configured so that the tray holding portion 7 can be moved only in the direction along the first rotation axis O1 and not moved in the other directions. That is, the tray holding part 7 is attached so as to swing around the first rotation axis O1 together with the holding part mounting table 5.

  The vibration motor 11 drives the tray holding unit 7 to vibrate in the direction (CD direction) along the first rotation axis O <b> 1 with respect to the holding unit mounting table 5 and is fixed to the lower surface 3 b of the base 3. . The output shaft 21 of the vibration motor 11 that can rotate about the second rotation axis O2 extends from the base 3 side toward the tray holding portion 7, and includes a through hole 3c formed in the base 3. The insertion hole 5 c formed in the holding unit mounting table 5 and the inner hole 7 c formed in the tray holding unit 7 are inserted. The tip of the output shaft 21 of the vibration motor 11 is attached to the base 3 via a bearing 23, and the linearity of the output shaft 21 is maintained by the bearing 23.

  Further, the insertion hole 5c of the holding unit mounting table 5 and the inner hole 7c of the tray holding unit 7 are formed to extend in the direction perpendicular to the first rotation axis O1. Thereby, even if the holding unit mounting table 5 and the tray holding unit 7 swing around the first rotation axis O1 with respect to the output shaft 21 of the vibration motor 11, the insertion hole 5c and the tray of the holding unit mounting table 5 are provided. A gap between the inner hole 7c of the holding portion 7 and the output shaft 21 and the bearing 23 of the vibration motor 11 is held (see FIG. 5). That is, even when the holding unit mounting table 5 and the tray holding unit 7 are swung, the output shaft 21 of the vibration motor 11 and its bearing 23 are prevented from coming into contact.

The distal end portion of the output shaft 21 of the vibration motor 11 is connected to the tray holding portion 7 via the vibration transmission mechanism 25.
As shown in FIGS. 1, 2, and 4, the vibration transmission mechanism 25 vibrates the rotation of the output shaft 21 of the vibration motor 11 in the direction along the first rotation axis O <b> 1 of the tray holding unit 7 (CD direction). An eccentric roller 27 fixed to the tip end of the output shaft 21 of the vibration motor 11 and a roller receiving portion 29 provided in the inner hole 7c of the tray holding portion 7 are provided. The eccentric roller 27 is fixed in a state where its center axis O3 is shifted with respect to the second rotation axis O2.

The roller receiving portion 29 is configured by a pair of receiving members 31 that sandwich the eccentric roller 27 from the vibration direction of the tray holding portion 7, and the guide surface 31 a of each receiving member 31 that contacts the outer peripheral surface of the eccentric roller 27 is a tray. It is orthogonal to the vibration direction of the holding part 7. Further, the lower end 31b of the guide surface 31a of each receiving member 31 located on the vibration motor 11 side is formed in an arc shape centering on the first rotation axis O1, and the guide surface 31a is formed on the first rotation axis O1. It is formed in the fan shape centering on.
In this vibration transmission mechanism 25, since the eccentric roller 27 rotates in contact with the guide surface 31a, the eccentric roller 27 and the receiving member 31 are preferably formed of a material with high wear resistance.

Next, the operation of the transfer device 1 configured as described above will be described.
In this transfer device 1, by rotating the output shaft 21 of the vibration motor 11, the eccentric roller 27 vibrates in the direction along the first rotation axis O <b> 1 with respect to the output shaft 21 of the vibration motor 11. Then, this vibration is transmitted to the tray holding part 7 via the pair of guide surfaces 31 a of the roller receiving part 29, and the tray holding part 7 performs a vibrating motion with respect to the holding part mounting table 5. Further, in this transfer device 1, by rotating the output shaft 13 of the swinging motor 9, the holding unit mounting base 5 and the tray holding unit 7 can be swung around the first rotation axis O1.

Here, since the guide surface 31a of each receiving member 31 is formed in a fan shape, as shown in FIG. 5, a pair of receiving members is used regardless of the swinging movement of the holding unit mounting table 5 and the tray holding unit 7. The state where the eccentric roller 27 is sandwiched by 31 is maintained. That is, the conversion from the rotation of the vibration motor 11 by the vibration transmission mechanism 25 to the vibration of the tray holding unit 7 is held.
Therefore, in this transfer device 1, both the vibration motion and the rocking motion can be imparted to the tray T attached to the tray holding portion 7.

As described above, according to the transfer device 1 according to the above embodiment, regardless of the swinging movement of the holding unit mounting table 5 and the tray holding unit 7 by the swinging motor 9, the holding unit mounting table 5 and the vibration motor 11 are used. The output shaft 21 does not interfere with each other, and the vibration transmission mechanism 25 converts the rotation of the output shaft 21 of the vibration motor 11 into the vibration of the tray holding unit 7. That is, the vibration movement of the tray holding unit 7 by the vibration motor 11 is not hindered by the swinging movement of the holding unit mounting table 5 and the tray holding unit 7.
Since both the swing motor 9 and the vibration motor 11 are fixed to the base 3, one of the swing motor 9 and the vibration motor 11 vibrates or swings together with the tray holding portion 7 as in the past. Can be prevented.

Therefore, the swing motor 9 and the vibration motor 11 do not require an extra capacity as in the prior art, so that the swing motor 9 and the vibration motor 11 are prevented from being enlarged and the transfer device 1 can be reduced in size. Can be planned. Furthermore, since the power consumption required for the operation of the transfer device 1 is reduced, the running cost of the transfer device 1 can be kept low.
Further, since the swing motor 9 and the vibration motor 11 are fixed to the base 3, a load is applied to the cables 10, 12 such as the power cable and the control cable of the swing motor 9 and the vibration motor 11. Therefore, the maintenance and inspection of the cables 10 and 12 can be performed with a long cycle, that is, the transfer device 1 can be easily handled.

As mentioned above, although one Embodiment of this invention was described, the technical scope of this invention is not limited to this, It can change suitably in the range which does not deviate from the technical idea of this invention.
For example, although the guide surface 31a of each receiving member 31 is formed in a fan shape with the first rotation axis O1 as the center, it is decentered by the pair of receiving members 31 at least regardless of the swinging movement of the tray holding portion 7. What is necessary is just to form so that the state which pinches | interposes the roller 27 may be hold | maintained. Therefore, the guide surface 31a of the receiving member may be formed in a rectangular shape, for example.
Further, although the guide surfaces 31 a that contact the eccentric roller 27 are formed on the pair of receiving members 31, they may be directly formed on the inner hole 7 c of the tray holding unit 7, for example.
