[0005] The chip-shaped electronic component 2 discharged from the hopper 4 is guided to a take-out position 3 through a guide passage (not shown). When passing through this guideway,
The chip-shaped electronic components 2 are aligned. As described above, the chip-shaped electronic components 2 sent to the take-out position 3 in the aligned state are sucked and held one by one by a suction nozzle (not shown) based on the vacuum suction, as described above. By moving the suction nozzle in this state, the suction nozzle is mounted at a desired position on the circuit board.

A plurality of supply units 1 having the hopper 4 and the guide passage as described above are provided in one chip mounter, and the plurality of supply units 1 are arranged in parallel. On the other hand, one suction nozzle is provided in one chip mounter, and is usually controlled so as to repeatedly reciprocate between two predetermined positions when performing a mounting operation. Therefore, in order to enable the desired chip-shaped electronic components 2 to be taken out in a desired order by the suction nozzle, the plurality of supply units 1 are moved as a whole by a desired distance in a desired direction, thereby being taken out. The take-out position 3 of the supply unit 1 for supplying the chip-shaped electronic component 2 to be fed is positioned at one end of the reciprocating operation of the suction nozzle.

In order to ensure that the desired chip-like electronic component 2 can be taken out by such a suction nozzle, the chip-like electronic component 2 is supplied without fail to the take-out position 3 of each supply unit 1 without interruption.

In the specific supply unit 1 shown in FIG. 4, compressed air supplied toward the chip-like electronic component 2 from the hopper 4 to the take-out position 3 is used as the above-mentioned driving means. The compressed air is introduced from an air inlet 7 provided in the vicinity of the hopper 4 and exerts a stirring action on the chip-shaped electronic components 2 in the hopper 4.
The chip-shaped electronic component 2 acts to be forcibly fed in the guide passage.

Further, in the supply unit 1, the chip-like electronic components 2 are surely sucked and taken out from the pick-up position 3 one by one, so that each time one chip-like electronic component 2 is sent to the pick-up position 3, the pick-up position is changed. A shutter 8 for opening and closing the shutter 3 is provided. The shutter 8 is operated as desired by a driving force applied via a link set 10 including a driving lever 9. The driving lever 9 has an L shape and is held so as to rotate about the pin 11 in the directions of arrows 12 and 13. Further, a tension spring 14 is provided in association with the driving lever 9, and the tension spring 14 urges the driving lever 9 to rotate in the direction of the arrow 13.

In a chip-type electronic component supply apparatus having a plurality of supply units 1 having such a configuration, one activation means 15 is provided.

FIG. 1 is a perspective view, partially cut away, showing a supply unit 31 provided in a chip-shaped electronic component supply device according to an embodiment of the present invention. Note that the supply unit 31 can be basically configured by changing or adding components to the supply unit 1 shown in FIG. 4 described above. Many elements corresponding to the elements shown in FIG. Therefore,
Elements corresponding to the elements shown in FIG. 4 are denoted by the same reference numerals, and redundant description may be omitted.

The supply unit 31 is for supplying a plurality of types of chip-shaped electronic components for each type, and a plurality of supply units 31 are provided in parallel in the chip-type electronic component supply device. . FIG. 1 shows one of the supply units 31. The supply unit 31 includes a hopper 4 that receives and discharges a plurality of chip-type electronic components 2 of a specific type, similarly to the supply unit 1 illustrated in FIG. In FIG. 1, the chip-shaped electronic component 2
, And a case 5 attached to the hopper 4 to introduce them into the hopper 4 is not shown.

The chip-like electronic component 2 discharged from the hopper 4 is guided to a take-out position 3 through a guide passage (not shown), similarly to the supply unit 1 shown in FIG. When passing through the guide passage, the chip-shaped electronic components 2 are in an aligned state. In this manner, the chip-shaped electronic components 2 sent to the take-out position 3 in the aligned state are sucked and held one by one by a suction nozzle (not shown) based on the vacuum suction. Is mounted at a desired position on the circuit board.

The chip-like electronic components 2 are reliably supplied to the take-out position 3 of each supply unit 31 without interruption, so that the desired chip-like electronic components 2 can be reliably taken out by the suction nozzle as described above. In this embodiment, each supply unit 31
Is provided with driving means for driving the supply of the chip-shaped electronic component 2 from the hopper 4 to the take-out position 3.

As the driving means described above, similarly to the supply unit 1 shown in FIG. 4, compressed air applied toward the chip-like electronic component 2 from the hopper 4 to the take-out position 3 is used. The chip-like electronic component 2 is introduced from an air inlet 7 provided near the hopper 4 to exert a stirring action on the chip-like electronic component 2 in the hopper 4 and to forcibly send the chip-like electronic component 2 in the guide passage. Act on.

However, in this embodiment, the compressed air supply nozzle 16 is not configured to selectively contact the air inlet 7 as shown in FIG. A tube 32 is fixedly connected. The compressed air is generated by a pump 33 driven by a mechanism described later, and is supplied to the air inlet 7 through a compressed air supply pipe 32.

Further, in the supply unit 31,
As in the supply unit 1 shown in FIG. 4, the chip-shaped electronic components 2 are sent to the take-out position 3 one by one.
Each time the chip-like electronic components 2 are sent to the take-out position 3,
A shutter 8 for opening and closing the take-out position 3 is provided. The shutter 8 is operated as desired by a driving force applied via a link set 10 including a driving lever 9.
The driving lever 9 is held so as to rotate about a pin 11 provided on a fixed wall 23 provided in the supply unit 31.

In this embodiment, the activating means 15 for activating the driving means including the pump 33 described above.
, A pusher 17 is provided. The pusher 17
As shown by arrows 20 and 21, it is operable up and down. The pusher 17 pushes one end of the driving lever 9 in the same direction as the pusher 17 shown in FIG. 4 when operating in the direction of the arrow 20 to rotate the driving lever 9 in the direction of the arrow 12, while the pusher 17 moves in the direction of the arrow. When operating in the 21 direction, it separates from the driving lever 9. At this time, the driving lever 9 rotates in the direction of the arrow 13 by the action of the tension spring 34. The tension spring 34 includes a pin 35 provided on the driving lever 9.
And a pin 36 provided on the fixed wall 23. As a result of the reciprocating rotation of the driving lever 9 in the directions of arrows 12 and 13, the shutter 8 is operated, and the chip-shaped electronic components 2 are sent to the take-out position 3 one by one.

In this embodiment, the driving lever 9 has a Z-shape, and a claw 37 is formed at the other end. A rotor 39 having a notch 38 is arranged facing the claw 37, and a large gear 40 is arranged so as to be arranged in parallel with the rotor 39. The rotor 39 and the large gear 40 are both fixed on a shaft 41. The shaft 41 is rotatably held by the fixed wall 23 and the bracket 42 provided on the fixed wall 23, so that the rotor 39 and the large gear 40 rotate integrally.

The small gear 43 is engaged with the large gear 40.
Is arranged. The small gear 43 is fixed on a shaft 44. The shaft 44 is rotatably held by the fixed wall 23 and the bracket 42. On the shaft 44,
Further, the cam 45 is fixed so that the cam 45 and the small gear 43 rotate integrally. A spiral spring 46 as energy storage means is arranged around the shaft 44. One end of the spiral spring 46 is fixed to the shaft 44, and the other end is fixed to the bracket 42. In this way, the spiral spring 46 is connected to the shaft 44
When it rotates, it stores the strain energy there.

A cam follower 47 is arranged in contact with the cam 45 described above. The cam follower 47 is attached to one end of a driven lever 48. Driven lever 48
Is rotatably held in the directions of arrows 50 and 51 about a pin 49 provided on the fixed wall 23. Further, between one end of the driven lever 48 and the bracket 42,
The tension spring 52 is connected. This tension spring 52
Rotates the driven lever 48 in the direction of the arrow 51, thereby biasing the cam follower 47 so as to maintain the cam follower 47 in contact with the cam 45.

At the other end of the driven lever 48, the above-described pump 33 is disposed. The pump 33 is mounted on the fixed wall 23. The pump 33 includes a plunger rod 53 extending from a plunger (not shown), and is configured to send compressed air to the compressed air supply pipe 32 by reciprocating the plunger rod 53.

The other end of the driven lever 48 is connected to the plunger rod 53 in order to reciprocate the plunger rod 53 by the rotation of the driven lever 48. More specifically, a connecting pin 54 is provided on the plunger rod 53,
The driven lever 48 has a hole 55 for receiving the connecting pin 54.
Is provided. The hole 55 is preferably an elongate hole, so that the difference between the arc-shaped motion locus of the end of the driven lever 48 and the linear motion locus of the plunger rod 53 can be absorbed. .

In such a configuration, when the supply unit 31 shown in FIG. 1 handles the chip-shaped electronic component 2 to be taken out by the suction nozzle, the supply unit 31 moves to the operating position of the pusher 17. Is done. In this state, the pusher 17 operates in the direction of arrow 20 and presses one end of the driving lever 9 to rotate the driving lever 9 in the direction of arrow 12 and then operates in the direction of arrow 21. Arrow 13 of the driving lever 9
Allows rotation in the direction.

The rotation of the driving lever 9 causes not only the operation of the shutter 8 but also the following operation as in the conventional case. That is, the driving lever 9
In the direction of arrow 12 of FIG.
The rotor 39 is rotated by a predetermined angle in the direction of the arrow 56 while engaging with the end wall of the notch 38 of FIG. by this,
Similarly, the large gear 40 rotates by a predetermined angle, and the small gear 43 meshing with the large gear 40 rotates by a predetermined rotation speed. This small gear 4
With the rotation of 3, the cam 45 also rotates. The rotation of the cam 45 causes the cam follower 47 to move up and down a predetermined number of times, and accordingly, the driven lever 48 is reciprocally rocked a predetermined number of times as shown by arrows 50 and 51.

As a result of the swing of the driven lever 48 described above, the plunger rod 53 reciprocates, whereby the pump 33
Discharges compressed air. This compressed air is introduced into the air introduction port 7 through the compressed air supply pipe 32, and as in the conventional case, exerts an agitating action on the chip-shaped electronic components 2 in the hopper 4 and also in the guide passage. It acts to forcibly send the chip-shaped electronic component 2.

In this way, the pusher 17 as the activating means 15 operates the movable mechanism including the driving lever 9, the rotor 39, the large gear 40, the small gear 43, the cam 45, the driven lever 48 and the like as the driving means. And pump 3
Activate 3 Also, it should be noted that when the shaft 44 rotates in accordance with the rotation of the above-described small gear 43, distortion occurs in the spiral spring 46, and as a result, distortion energy is stored. As described above, after the pusher 17 as the activating means 15 activates the pump 33 as the driving means as described above, the pusher 17 operates in the direction of the arrow 21 and the driving lever is driven as follows. It is released when 9 is turned in the direction of arrow 13.

That is, when the driving lever 9 is rotated in the direction of arrow 13, the pawl 37 moves in a direction away from the end wall of the notch 38 of the rotor 39, and accordingly, the rotor 3
9 is released from the restraint by the driving lever 9, and the movable mechanism from the rotor 39 to the cam 45 is in a state where it can operate freely. At this time, as described above, the spiral spring 46
Act on the shaft 44 to release this energy and rotate the shaft 44 in the opposite direction to that described above.

Thus, the cam 45 rotates again. This rotation of the cam 45 causes the up and down movement of the cam follower 47 and the reciprocating swing of the driven lever 48 as in the case described above. And, by the swing of the driven lever 48,
The plunger rod 53 reciprocates, and the pump 33 discharges compressed air. This compressed air is also introduced into the air introduction port 7 through the compressed air supply pipe 32 and exerts an agitating action on the chip-shaped electronic components 2 in the hopper 4, and the chip-shaped electronic components in the guide passage. Acts to force 2 to be sent.

As described above, the strain energy stored in the spiral spring 46 is released only when the pusher 17 moves the arrow 2.
Operating in one direction, the driving lever 9 rotates in the direction of arrow 13, and as a result, the pawl 37
At the time when the rotor 39 is released from the restraint by the driving lever 9 and the movable mechanism from the rotor 39 to the cam 45 can freely operate, In other words, this is the time after the chip-shaped electronic component 2 has been taken out.

According to this embodiment, since the energy stored in the spiral spring 46 is released in the supply unit 31 at the above-mentioned time, the pump 33 is operated again by this energy, and compressed air is introduced into the air. It can be introduced again into the mouth 7. Therefore, even after the removal of the chip-shaped electronic component 2, the hopper 4 is ready for the removal of the next coming chip-shaped electronic component 2.
The above-mentioned compressed air can be made to act so as to stir the chip-shaped electronic components 2 therein and to send the chip-shaped electronic components 2 in the guide passage.

Therefore, even if the speed of the chip mounter is further increased and the number of times that the chip-shaped electronic component 2 is taken out per unit time by the suction nozzle is increased, the chip-shaped electronic component 2 is moved to the take-out position 3 of the supply unit 31. Since the supply can sufficiently follow the removal of the chip-shaped electronic component 2 by the suction nozzle, it is possible to sufficiently cope with an increase in the speed of the chip mounter.

In this embodiment, a spring capable of storing distortion energy, such as a spiral spring 46, is used as the energy storage means, and since this energy is finite, when predetermined energy is released, The movable mechanism including the cam 45 and the like automatically stops, and as a result, the pump 3
3 also stops automatically. Therefore, undesired abrasion and mechanical damage of the chip-shaped electronic component 2 due to excessive stirring of the chip-shaped electronic component 2 by the compressed air without providing any special means for stopping the pump 33 or the like. Does not occur.

In the embodiment shown in FIG. 1 described above, the bracket 42 is shown with a relatively large projecting dimension from the fixed wall 23, but is arranged above the bracket 42. Rotor 39, large gear 40,
The purpose is to more clearly illustrate the positional relationship between the elements such as the small gear 43, the cam 45, and the spiral spring 46.
The overhang dimension of the bracket 42 is made smaller, and elements such as the rotor 39, the large gear 40, the small gear 43, the cam 45, and the spiral spring 46 are arranged more compactly.

FIG. 2 illustrates another embodiment of the present invention. The supply unit 61 provided in the chip-shaped electronic component supply device shown in FIG. 2 includes a hopper 62 that receives and discharges a plurality of chip-shaped electronic components 2.
The hopper 62 has a funnel shape, and the chip-shaped electronic components 2 discharged from the hopper 62 are aligned at a discharge port 63 provided at the bottom thereof to a predetermined take-out position (not shown). A guide pipe 64 that forms a guide passage for guiding is inserted.

The guide pipe 64 has an upper end portion 65 and a remaining portion 66.
And divided into The upper end portion 64 and the remaining portion 66 are both held by the pipe receiver 67.
5 can be vibrated vertically with respect to the discharge port 63. The vibratable configuration of the upper end 65 functions as a driving unit for driving the supply of the chip-shaped electronic component 2 from the hopper 62 to the take-out position. By exerting a stirring action on the electronic component 2, it acts to make it easier to receive the chip-shaped electronic component 2 in the guide pipe 64 in an aligned state.

The vertical vibration of the upper end 65 described above is
A driven lever 68 corresponding to the driven lever 48 shown in FIG.
Driven by That is, like the driven lever 48, the driven lever 68 can reciprocate and swing as shown by arrows 69 and 70, and the end of the driven lever 68 is formed by a pair of protrusions provided on the upper end 65. By engaging between the portions 71 and 72, the swing of the driven lever 68 is transmitted, and the upper end portion 65 vibrates in the vertical direction.

The mechanism for reciprocating the driven lever 68 is substantially the same as the mechanism for reciprocating the driven lever 48 described above. FIG. 3 is for explaining still another embodiment of the present invention.
The supply unit 81 provided in the chip-shaped electronic component supply device illustrated in FIG. 3 includes a hopper 82 that receives and discharges a plurality of chip-shaped electronic components 2. The hopper 82 has a funnel shape, and has a discharge port 83 provided at the bottom thereof.
A guide pipe 84 forming a guide passage for guiding the chip-shaped electronic components 2 discharged from the hopper 82 to a predetermined take-out position (not shown) is fixedly connected.

The guide pipe 84 is held by a pipe receiver 85 such that it can vibrate vertically. In this embodiment, since the guide pipe 84 and the hopper 82 are fixedly connected to each other, the hopper 82 is also vibrated in the vertical direction with the vertical vibration of the guide pipe 84. The oscillating configuration of the hopper 82 and the guide pipe 84 functions as a driving unit for driving the supply of the chip-shaped electronic component 2 from the hopper 82 to the take-out position. By exerting a stirring action on the chip-shaped electronic component 2, the chip-shaped electronic component 2 acts to make it easier to receive the chip-shaped electronic component 2 in an aligned state into the guide pipe 84, and By imparting vibration to the chip-shaped electronic component 2, the movement of the chip-shaped electronic component 2 in the guide pipe 84 is made smoother.

The hopper 82 and the guide pipe 84 described above

Although the present invention has been described with reference to the illustrated embodiments, various other embodiments are possible within the scope of the present invention.

For example, although the spiral spring 46 is used as the energy storage means in the above-described embodiment, another form of spring may be used. Further, other energy storage means may be used instead of the spring for storing such strain energy. The energy stored by such energy storage means may be, for example, electrical energy in addition to mechanical energy such as strain energy. In the case of storing electric energy, a part of mechanical energy for activating the driving means by the activating means is converted into electric energy by power generation or the like, and the electric energy is charged. The charged electrical energy is discharged to reactivate the driving means.
