With reference to the attached drawings, an embodiment embodying the present invention will be described to help the understanding of the present invention. As shown in FIGS. 1 and 2, the electronic component transporting device 10 according to the embodiment includes a rotating body 12 and a pressing device 13. A component support device 11 that supports the electronic component W is movably attached to the rotating body 12 in a vertically downward direction (an example of the first direction). The pressing device 13 pushes the component supporting device 11 to move the component supporting device 11 vertically downward with respect to the rotating body 12. Hereinafter, a detailed description will be given.

As shown in FIGS. 1 and 2, the electronic component transfer device 10 includes a component moving unit 14 and a plurality of pressing devices 13. The component moving unit 14 has a plurality of component supporting devices 11 and a rotating body 12 to which the plurality of component supporting devices 11 are attached, and intermittently moves the electronic component W. The pressing device 13 pushes down the component supporting device 11 to lower the electronic component W. Examples of the electronic component W include diodes, transistors, capacitors, inductors, and ICs (Integrated Circuits).

As shown in FIG. 2, the component moving unit 14 has a rotating body drive motor 17, which is an example of a drive source. The rotating body drive motor 17 is fixed to the plate member 16 mounted on the base base 15. Rotating body drive motor 17 The rotating body driving motor 17 is connected to a disk-shaped rotating body 12 arranged horizontally. As shown in FIGS. 1 and 2, M (M ≧ 2, M = 12 in this embodiment) component support devices 11 are attached to the rotating body 12 at equal pitches along the outer circumference. The electronic component W adsorbed on the rotating body 12, each component supporting device 11, and the component supporting device 11 has an angle corresponding to the arrangement pitch of the component supporting device 11 for each drive of the rotating body drive motor 17 (in the present embodiment, Rotation (30 °) (clockwise rotation around the rotating body 12) is performed.

As shown in FIGS. 2 and 3A, each component support device 11 includes a suction nozzle 18 and a long member 19 extending in the horizontal direction. The suction nozzle 18 is long in the vertical direction and is attached to the rotating body 12 so as to be able to move up and down while penetrating the rotating body 12. One end of the long member 19 is connected to the upper end of the suction nozzle 18. At the lower end of the suction nozzle 18, the electronic component W is sucked by vacuum pressure, and the sucked electronic component W is released to the atmosphere or by vacuum breaking. As shown in FIG. 2, a coil spring 21 that exerts an upward force on the component support device 11 is mounted on a portion of the suction nozzle 18 that protrudes upward from the rotating body 12.

Further, as shown in FIG. 2, a disk-shaped plate member 23 held horizontally by the support member 22 is provided above the rotating body 12. A plurality of pressing devices 13 are attached to the outer periphery of the plate material 23. Each pressing device 13 is provided below the slide drive motor 25 attached to the holding member 24 fixed to the plate member 23, the slide member 26 mounted on the holding member 24 so as to be able to move up and down, and the slide drive motor 25. A coil spring 27 that applies an upward force to the lowered slide member 26 is provided. The slide member 26 extends in the vertical direction. A roller (an example of a rotating object) 28 is provided at the lower end of the slide member 26. The rotation axis of the roller 28 is arranged substantially perpendicular to the rotation axis of the rotating body 12.

In the present embodiment, the slide drive motor 25 is connected to the output shaft 29 that moves up and down by the drive of the slide drive motor 25. The slide member 26 is pushed down by the output shaft 29 and descends. Further, the slide member 26 rises due to an upward force applied from the coil spring 27 as the output shaft 29 rises. Needless to say, the slide member 26 may be pushed down by a design different from that of the present embodiment, such as adopting a cam and a cam follower instead of the output shaft 29.

Each pressing device 13 has K (hereinafter, also simply referred to as “pause position”) of M pause positions (hereinafter, also simply referred to as “pause positions”) in which the component support device 11 and the electronic component W adsorbed on the component support device 11 are paused. It is arranged above the temporary stop position (first stop position) of M ≧ K). In each pressing device 13, when the output shaft 29 is lowered by the operation of the slide drive motor 25, the slide member 26 is lowered (moved in the first direction), the roller 28 is in contact with the long member 19, and the suction nozzle 18 and the suction nozzle 18 are lowered. The long member 19 (that is, the component support device 11) is lowered. At that time, the electronic component W adsorbed on the suction nozzle 18 descends (moves in the first direction) together with the suction nozzle 18 and the long member 19.

In the present embodiment, in the component support device 11, the long member 19 corresponds to the contacted portion with which the pressing device 13 contacts, and the lower end portion of the suction nozzle 18 sucks (supports) the electronic component W. Corresponds to. As shown in FIG. 3A, in the component support device 11, the long member 19 extends downstream in the rotation direction of the rotating body 12 with reference to the lower end of the suction nozzle 18. Since the slide member 26 includes the roller 28, the frictional force generated when the slide member 26 comes into contact with the component support device 11 and during the contact is suppressed.

As shown in FIG. 1, in the vicinity of the rotating body 12, there are K electronic components W that are temporarily stopped at K first stop positions (hereinafter, also referred to as “position P”) in which the pressing devices 13 are arranged upward. , Position correction unit 31 (unit for positioning electronic component W), visual inspection units 32, 33 (unit for visual inspection of electronic component W) and electrical characteristic inspection unit 34 (electrical characteristics of electronic component W) that perform predetermined processing. A unit to inspect) is provided. The rotating body drive motor 17 intermittently rotates the rotating body 12 to move the electronic component W to the position P and temporarily stop it at the position P. The position correction unit 31, the

visual inspection unit

32, 33, and the electrical characteristic inspection unit 34 each perform a predetermined process on each electronic component W arranged at the position P.

Next, the movement of the electronic component W to the position P and the movement from the position P will be described. As shown in FIG. 3A, the suction nozzle 18 (that is, the support portion) and the electronic component W sucked by the suction nozzle 18 are positioned as the rotating body 12 is rotated by the operation of the rotating body drive motor 17. When approaching P, the slide member 26 begins to descend due to the operation of the slide drive motor 25. As shown in FIG. 3B, the roller 28 (rotating object) of the slide member 26 is further lowered while being in contact with the long member 19 (contacted portion), so that the component support device 11 and the electronic component W are lowered. To start. As a result, the component support device 11 and the electronic component W start to move diagonally downward.

The rotating body 12 continues to rotate while the slide member 26 pushes down the component support device 11 and the electronic component W while the roller 28 is in contact with the long member 19. Therefore, as shown in FIG. 3C, the component support device 11 and the electronic component W continue to move diagonally downward. After the slide member 26 stops descending (or at the timing when the slide member 26 stops) due to the stop of the slide drive motor 25, the rotating body 12 temporarily stops. As a result, as shown in FIG. 4A, the component support device 11 and the electronic component W are stopped, and the movement of the suction nozzle 18 and the electronic component W to the position P is completed. While the rotating body 12 is rotating, the slide member 26 may pause or rise once or a plurality of times during the descent. When the slide member 26 pauses or rises once or multiple times during the rotation of the rotating body 12, the electronic component W and the component support device 11 move diagonally downward, horizontally, and / or diagonally. It will move toward the position P while moving upward.

In this state, the position correction unit 31 (the same applies to the

visual inspection units

32 and 33 and the electrical characteristic inspection unit 34) performs a predetermined process on the electronic component W. Here, since the slide drive motor 25 adjusts the descending distance (moving distance in the first direction) of the slide member 26, the component support device 11, and the electronic component W by adjusting the rotation speed, it depends on the type of the electronic component W and the like. It is possible to change the height (vertical direction) position of the electronic component W at the position P.

After the processing of the electronic component W by the position correction unit 31 is completed, the component support device 11 and the electronic component W are raised by raising the slide member 26 by the operation of the slide drive motor 25. As shown in FIG. 4B, the slide member 26 is further raised even after the component support device 11 is raised to the upper limit position and the roller 28 is separated from the long member 19. After that, the rotation of the rotating body 12 by the operation of the rotating body driving motor 17 causes the component support device 11 and the electronic component W to move horizontally, and the suction nozzle 18 and the electronic component W to move from the position P.

As described above, in the electronic component transfer device 10, the electronic component W is moved in parallel with the rotation operation of the rotating body 12 until the electronic component W is arranged from the temporary stop position on the upstream side of the position P to the position P. Descend (move in the first direction). Therefore, when the descent of the electronic component W is started after the electronic component W is arranged at the position P, that is, when the time for lowering the electronic component W to a predetermined position is added to the rotation time of the rotating body 12 is provided. As compared with the above, the time from the start of rotation of the rotating body 12 to the start of a predetermined process on the electronic component W by various units such as the position correction unit 31 can be shortened. As a result, the number of electronic components W transported per unit time is increased.

In the component support device 11 of the electronic component transfer device 10 described so far, the long member 19 (contacted portion) extends downstream in the rotation direction of the rotating body with reference to the lower end portion (support portion) of the suction nozzle 18. However, it is not limited to this. For example, a component support device in which the contacted portion extends upstream of the rotating body in the rotational direction with respect to the support portion may be adopted. When such a component support device is adopted, the rotating body rotates as the slide member rises after various units perform predetermined processing on the electronic component, and the component support device and the electronic component move diagonally upward. This also makes it possible to increase the number of electronic components transported per unit time. During the rotation of the rotating body, the slide member may be paused or lowered once or multiple times in the middle of ascending, in which case the electronic component W and the component supporting device move diagonally upward and horizontally. Move away from position P while moving and / or moving diagonally downward.

Further, a component support device in which the contacted portion extends to both the downstream side and the upstream side in the rotation direction of the rotating body with respect to the support portion may be adopted. In this case, the time required for approaching and descending the electronic component from the position P and the time required for moving and ascending from the position P of the electronic component can be shortened.

Further, the contact portion of the pressing device that contacts the component support device extends to either or both of the downstream side and the upstream side in the rotation direction of the rotating body with reference to the position P, so that the electronic component per unit time The number of transports may be increased. With reference to FIGS. 5 (A) and 5 (B), the horizontal member (an example of the contact portion) 42 of the pressing device 41 in contact with the component support device 40 is in the rotation direction of the rotating body with reference to the position P. A modified example extending to the upstream side will be described.

As shown in FIG. 5A, the component support device 40 has a suction nozzle 44 extending in the vertical direction. A roller (an example of a rotating object with which the contact portion comes into contact) 43 is provided above the suction nozzle 44. The pressing device 41 has a slide member 45. The slide member 45 includes a vertically elongated member 46 arranged at the position P and a horizontally extending horizontal member 42 connected to the lower end of the vertically elongated member 46. The pressing device 41 of the component supporting device 40 differs from the pressing device 13 of the electronic component transporting device 10 in the structure of the slide members (45, 26), but the other members and parts of the pressing device 41 of the component supporting device 40 are different. , The members and parts (slide drive motor 25, output shaft 29, coil spring 27, etc.) of the pressing device 13 of the electronic component conveying device 10 may be the same. The horizontal member 42 extends to the upstream side in the rotation direction of the rotating body to which the component support device 40 is vertically attached with reference to the position P.

When the suction nozzle 44 is moved to the position P together with the electronic component W sucked by the suction nozzle 44 due to the rotation of the rotating body, the slide member 45 is lowered. As a result, as shown in FIG. 5B, the horizontal member 42 comes into contact with the roller 43. From this state, the rotating body continues to rotate and the slide member 45 continues to descend, so that the electronic component W is conveyed to the position P while moving diagonally downward together with the component support device 40. The rotation axis of the roller 43 is substantially perpendicular to the rotation axis of the rotating body.

Here, the vertically long member of the pressing device does not need to be arranged at the position P. As shown in FIG. 6, a slide member 52 having a vertically elongated member 50 arranged at a position different from the position P and a horizontal member 51 connected to the lower end portion of the vertically elongated member 50 can be adopted. The horizontal member 51 extends downstream in the rotation direction of the rotating body with reference to the position P. A roller 53 is attached to the horizontal member 51 on the upstream end side in the rotation direction of the rotating body. The horizontal member 51 is connected to the vertically elongated member 50 on the downstream end side in the rotation direction of the rotating body. The component support device 54 with which the rollers 53 come into contact has a suction nozzle 55 and a long member 56. The suction nozzle 55 sucks the electronic component W. The center of the long member 56 is connected to the suction nozzle 55. The long member 56 is an example of a contacted portion extending in both the upstream side and the downstream side in the rotation direction of the rotating body with reference to the suction nozzle 55.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and all changes in conditions that do not deviate from the gist are within the scope of the present invention. For example, in the component support device, the contacted portion extending to either one or both of the downstream side and the upstream side in the rotation direction of the rotating body with respect to the support portion does not need to be horizontally arranged, and the contact portion does not need to be horizontally arranged. It may be arranged diagonally. Further, a component support device that supports the electronic component by sandwiching the electronic component may be adopted. Then, neither the pressing device nor the component supporting device need to be provided with a rotating object. When either or both of the pressing device and the component supporting device include a rotating object, the rotating object may be something other than a roller, for example, a ball.

Further, the first direction is not limited to the vertical downward direction, and may be, for example, one horizontal direction. Further, the rotating body does not have to be arranged horizontally, and for example, a rotating body that is vertically arranged and rotates about a horizontal axis can be adopted. The motor included in the pressing device may not be able to adjust the moving distance of the slide member in the first direction.

According to an embodiment of the present invention, in the electronic component transfer device 10, the contacted portion 19 of the component support device 11 with which the pressing device 13 contacts supports the component support device 11 in which the electronic component W is supported. With reference to the portion, the rotating body 12 extends to either one or both of the downstream side and the upstream side in the rotation direction. Further, according to another embodiment of the present invention, in the electronic component transfer device, the contact portion 42 of the pressing device 41 in contact with the component support device 40 is on the downstream side in the rotation direction of the rotating body with reference to the position P. And extends to either or both of the upstream side. According to the electronic component transfer device of these embodiments, when the electronic component W is approaching the position P, the

component support devices

11 and 40 are moved in the first direction by the

pressing devices

13 and 41, and When the electronic component W is moving from the position P, the

pressing devices

13 and 41 can move the

component support devices

11 and 40 in the opposite direction of the first direction, or both. As a result, the number of electronic components that can be transported per unit time can be increased.
