Also, the present invention relates to a device for supplying a radial taping electronic component for transferring to an insertion head.

[Prior Art] In an automatic electronic component insertion device that automatically inserts electronic components into a printed circuit board, the position at which the electronic components are supplied to the insertion head is determined, and the electronic components are supplied up to the position. An electronic component supply device is provided for automatically transferring the components. This electronic component supply device is provided with a structure corresponding to various types of electronic components (for example, radial taping electronic components and axial taping electronic components) together with the insertion head.

By the way, as shown in FIG. 8, an insertion spindle 101 is used for an insertion head for inserting a radial taping electronic component.
There is a type in which all the operations from the holding to the insertion of the electronic component are performed only by the axial movement (movement in the direction of arrow a), opening / closing of the holding claw 102, and swinging movement (movement in the direction of arrow b). Here, the opening and closing and swinging motion of the holding claw 102 can be interlocked with the axial motion of the insertion spindle 101 via a cam mechanism or the like. Therefore, the insertion head 100 is widely used because it can be driven by a single drive source and is very easy to control.

In the drawing, 201 is a sprocket for transferring electronic components, which receives a driving force from a driving mechanism 203 via a timing belt 202 and rotates intermittently. On the other hand, 1 is a tape, and a large number of electronic components 2 are attached at regular intervals so as to be orthogonal to the longitudinal direction of the tape. Further, the tape 1 is provided with holes 3 at regular intervals, and when the engaging protrusions of the sprocket 201 engage with the holes 3, the electronic parts can be transported in a winding manner. Was there.

With the diversification of electronic components to be inserted, in order to be able to insert various electronic components, in the electronic component automatic insertion device, a plurality of electronic component supply devices are arranged side by side in the width direction. It is arranged.

As shown in FIG. 9, the above-described conventional electronic component supply device supplies the electronic component 2 in a posture in which the electronic component 2 is laid sideways. When the electronic component 2 is supplied in such a posture, the insertion head 100 described above has a structure that realizes the insertion operation only by the axial movement of the insertion spindle 101, the opening and closing of the holding claw 102, and the swinging movement. It was necessary to receive the electronic component 2 from the side. That is, the insertion head 100 is
As shown, it had to be installed laterally on the tip of the feeder.

[Problems to be Solved] As described above, in the above-described conventional electronic component supply device,

In addition to the supply device having the above-described structure, there is also a supply device that planarly transfers and supplies electronic components in an upright posture.
However, with respect to such a supply device, since the insertion spindle has to be moved in the vertical direction and the horizontal direction, there is a drawback that the control mechanism becomes complicated as the number of drive sources increases.

The present invention has been made in view of the above-mentioned circumstances, and enables automatic insertion of electronic components by allowing the electronic components to be held from the front position of the device (right position in Fig. 9) even with an insertion head having a single drive source. An object of the present invention is to provide a device for supplying a radial taping electronic component, which can prevent an increase in the lateral width of the wearing device and realize the downsizing of the device.

[Means for Solving Problems] In order to achieve the above-mentioned object, the first invention is to hold taped radial lead electronic components and send them out one by one at a predetermined timing, cut the lead wires and supply them to the insertion head. In the radial taping electronic component feeder, the lead wire bending means for bending the lead wire of the electronic component at a substantially right angle to the tape in synchronization with the feeding of the tape on which the electronic component is taped is used as the tape transfer path. It is arranged.

Further, in the first invention, preferably, the lead wire bending means supports a lead wire bending auxiliary member that supports a portion of a certain length from the tip of the lead wire from above, and an outer portion of the lead wire bending auxiliary member. And a lead wire bending member which slides along the tip of the auxiliary member in a direction substantially perpendicular to the tape from below and a predetermined timing in synchronization with the feeding of the lead wire bending member. Drive means for driving with.

Further, a second invention is to hold the taped radial lead electronic parts and send them out one by one at a predetermined timing, and the electronic parts by the lead wire bending means arranged along the tape transfer path where the electronic parts are taped. In the apparatus for supplying radial taping electronic components, the lead wire is bent at a substantially right angle to the tape, and then the lead wire is cut and supplied to the insertion head. The lead wire bending auxiliary member that supports the upper side of the bent portion, and the lead wire bending auxiliary member that is provided outside the lead wire bending auxiliary member along the tip of the auxiliary member and cooperates with the auxiliary member when the tape is transferred.

It is slidably supported on the side of 0. The base end of the lead wire bending member 28 is connected to the lever 27 via a pin 29. Therefore, the lead wire bending member 28 is
As 27 rotates, it slides in the directions of arrows c and d in FIG. When sliding in the direction of arrow c, the lead wire bending member 28
The tip of the push-up pushes up the lead wire 2a of the one electronic component transferred onto the peripheral surface of the sprocket 10 to bend the lead wire (see FIG. 4).

Further, in FIG. 4 (see also FIGS. 1 and 2), 30 is a lead wire bending auxiliary member, which is a portion of a certain length from the tip of the lead wire 2a pushed up by the lead wire bending member 28. It is located above (for example, the portion where the tape 1 is attached). The lead wire bending member 28 and the lead wire bending auxiliary member 30 cooperate with each other to bend the lead wire 2a of the electronic component 2 at a substantially right angle.

A clearance substantially corresponding to the diameter of the lead wire 2a is set between the lead wire bending member 28 and the lead wire bending auxiliary member 30.

In FIGS. 2 and 5, 31 is a lead wire of the electronic component 2.

The rotation of 33 causes the cutting blade 33a formed at the tip of the arm 33 to move the lead 2 of the electronic component 22 at the supply position II.
It is designed to disconnect a. A roller 35 is attached to the base end of the arm 33, and a rod-shaped rod 36 having a wedge-shaped tip for arm closing is inserted between the rollers 35, 35 to expand the space between the rollers 35, 35. The arms 33, 33 are rotated in the closing direction. The bar 36 is connected to the lever 27,
It moves in the axial direction in conjunction with the rotation of the lever 27 described above.

A tension spring 37 urges the rod 36 and the lever 27. The tension spring 37 causes the rod 36 to retract, and causes the cam roller 25 to abut on the cam 24.

Next, the operation of the radial taping electronic component supply device configured as described above will be described.

In the radial taping electronic component, the hole 3 of the tape 1 is engaged with the engaging protrusion 10a of the sprocket 10, and
It is mounted on the electronic component supply device in a state of being laid sideways along the transfer path I.

First, when the cylinder rod 18 is moved forward (forward) by driving the hydraulic cylinder 17, the lever 19 rotates in the counterclockwise direction around the center line 13 in the drawing. The feed claw 20 also rotates with the rotation of the lever 19 and engages with the tooth one pitch ahead in the ratchet wheel 12.

At the same time, the cam 24 rotates in the same direction as the lever 19 rotates in the counterclockwise direction (see FIG. 2).
Then, the cam roller 25 and the lever 27 rotate counterclockwise in the figure around the support shaft 26, and in conjunction with this, the lead wire bending member 28 slides in the direction of arrow c. Then, as shown in FIG. 3, the lead wire bending member 28 and the lead wire bending auxiliary member 30 cooperate to bend the lead wire 2a of the electronic component 2 at a substantially right angle.

Further, the rod 36 moves forward in conjunction with the rotation of the lever 27 in the counterclockwise direction in the figure, and the gap between the rollers 35, 35 of the cutter 31 is expanded. As a result, the blade 3 formed at the tip of the arms 33, 33
3a is closed and the lead wire 2a of the electronic component 2 is cut.

Next, when the cylinder rod 18 is retracted (returned),
The feed claw 20 rotates together with the lever 19 in the clockwise direction in the drawing.
This rotation of the feed pawl 20 causes the ratchet wheel 12 to intermittently rotate by one pitch.

The rotation of the ratchet wheel 12 is transmitted to the sprocket 10 via the timing pulleys 14 and 15 and the timing belt 16.
As a result, the sprocket 10 rotates in the clockwise direction in the figure by a predetermined amount, and the next electronic component 2 is transferred to the supply position II. Also,
As the sprocket 10 rotates, the roller of the positioning member 23
The positioning gear 22 rotates while pushing out 23a, and when it has rotated by one pitch, the roller 23 of the positioning member 23 is again rotated.
The electronic component 2 is positioned by engaging with a. At this time, the lead wire bending member 28 retracts in the direction of arrow d as the lever 27 rotates in the opposite direction, and the bar 36 retracts to its original position by the urging force of the tension spring 37.

In this way, the electronic component 2 with the lead wire 2a bent is then transferred to the supply position II. Supply position
In II, the gripping claw 102 of the insertion head 100 rotates in the vertical direction from the front of the supply device, and the lead wire 2a of the electronic component 2
Pinch. The rod 36 is retracted by the urging force of the tension spring 37.

Due to the above-mentioned kind of operation, the electronic component 2 is inserted into the insertion head 10
It can be handed over to 0.

FIG. 6 is a cross-sectional view showing an embodiment of the second invention device and corresponds to FIG. 4 shown previously.

In this embodiment, the lead wire bending means of the electronic component is changed, and the other overall structure is the same as that of the above-mentioned embodiment, and therefore the description other than the lead wire bending means will be omitted.

That is, in this embodiment, as the lead wire bending member 41, an arc-shaped block having a twisted surface 42 as shown in FIG. 7 is used. The twisted surface 42 forms the upper surface of the member at the one end portion 42a, and twists by about 90 ° until reaching the other end portion 42b, and eventually the other end portion 42b is flush with the side surface of the member. ing. Further, the height of the member is the lowest at the one end portion 42a and becomes higher toward the other end portion 42b.

The lead wire bending member 41 is fixed to the lateral side of the sprocket 10 in a state where a clearance corresponding to the diameter of the lead wire is provided between the lead wire bending member 41 and the tip of the lead wire bending auxiliary member 30. Here, the upper edge of the one end 42a is the sprocket 1
It is arranged below the lead wire 2a of the electronic component 2 transferred onto the peripheral surface of 0, while the other end portion 42b has the same lead wire 2a.
It is arranged at a predetermined height above.

With the above-described configuration, the lead wire bending member 41 and the lead wire bending auxiliary member 30 cooperate with each other to form a lead wire for an electronic component.
2a can be bent almost at right angles. That is, with respect to the electronic component 2 transferred by the rotation of the sprocket 10, a portion of a certain length from the tip of the lead wire 2a (for example,
The lead wire bending assisting member 30 is located above the portion (where the tape 1 is attached). On the other hand, the twisted surface 42 of the lead wire bending member 41 comes into contact with the portion of the lead wire 2a outside the portion where the lead wire auxiliary member 30 is located from below.

Then, when the transfer of the electronic component 2 proceeds, the lead wire 2a becomes
While being sandwiched between the lead wire bending auxiliary member 30 and the lead wire bending member 41, the lead wire bending auxiliary member 30 moves along the twisted surface 42, and thus is gradually bent. Since the twisted surface 42 is twisted by 90 ° between both ends, the lead wire 2a is bent at a substantially right angle before reaching the other end 42b.

In this way, the electronic component 2 with the bent lead wire 2a is then transferred to the supply position II, and the lead wire 2a
For cutting and feeding the insertion head 100.

The present invention is not limited to the embodiments described above. For example, the bending of the lead wire may be performed on the electronic component before being transferred onto the peripheral surface of the sprocket.

Further, as the means for transferring the electronic component and the means for cutting the lead wire, various known techniques other than those shown in the drawings can be used.

Further, the object of the present invention was premised on the supply to the insertion head operating with a single drive source as shown in FIG. 8, but in carrying out the invention, a configuration other than that shown in FIG. The insertion head can also be the supplier of electronic components.

[Advantages of the Invention] As described above, the radial taping electronic component feeder according to the first aspect of the invention is configured such that the lead wire of the electronic component is bent substantially perpendicular to the tape in synchronization with the feeding of the tape. In the supply position, the electronic parts are directed toward the front of the device. Therefore, the insertion head is a single drive source that receives the electronic parts by the axial movement of the insertion spindle, the opening and closing of the holding claw, and the swinging movement. However, the electronic component can be received from the position in front of the device. As a result, there is an effect that the electronic component automatic insertion device can be downsized.

Further, the second invention in which the lead wire bending means is composed of the lead wire bending auxiliary member and the lead wire bending member also has the same effect as the first invention.
