DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a taping device for electronic components, and more particularly to a radial type taping device for electronic components.

In general, automation has recently progressed in the process of mounting electronic components onto printed circuit boards, etc., and automatic insertion devices are often used. During this automatic insertion, the taped position of the electronic component and the pitch between the multiple leads of each electronic component are important dimensions, and any misalignment will cause insertion errors and reduce the automation rate and the quality of the product. lower.

FIG. 1 is a plan view of a taped electronic component.

As shown in FIG. 1, the leads 11 of a radial type electronic component 1, in which a plurality of leads 11 are provided in one direction, are sandwiched and fixed between a mount 2 and an adhesive tape 3. In this way, a large number of electronic components 1 arranged at regular intervals are loaded into an automatic insertion device to automate assembly.

In this case, it is important that the mutual arrangement pitch a of the electronic components 1 and the pitch b of the leads 11 of each electronic component 1 are set to predetermined values. In addition, mount 2
A hole 21 provided in is a guide hole for feeding the mount.

As shown in FIG. 2, the conventional taping device for electronic components has a recess 41 on its outer circumferential surface into which the electronic components 1 arranged at a predetermined arrangement pitch a are inserted, and each time the electronic components 1 are rotated by an angle corresponding to the arrangement pitch a. A taping drum 4a performs step rotation in one direction and stops for a predetermined period of time, and a mount 2 moves in synchronization with the step rotation of the taping drum 4a in contact with the outer circumferential surface between the lead and the outer circumferential surface of the electronic component 1. , a roller 3-1 rotatably supported on an axis parallel to the taping drum 4a, and an adhesive tape 3 that is supplied to the taping drum 4a via the roller 3-1 and adheres to the mount 2 across the lead of the electronic component 1. and a pressure bonding punch 6 to which a pressure bonding rubber 7 is fixed, which moves toward the outer peripheral surface and presses the adhesive tape 3 while the taping drum 4a is stopped.

In such a configuration, the electronic components 1 are sequentially inserted into the recesses 41 of the taping drum 4a that rotates in steps in the direction of the arrow B, the leads of the electronic components 1 are sandwiched between the mount 2 and the adhesive tape 3, and the electronic components 1 are fixed to the crimping portion 6. The electronic component 1 was taped by pressing the adhesive tape 3 onto the mount 2 using the pressure rubber 7. Therefore, although the pitches between the electronic components are arranged at predetermined dimensions, it is not possible to correct the pitch dimension between the leads for each electronic component, so it is necessary to correct the deformation of the leads for each electronic component before supplying the electronic components to the taping drum. There is a drawback that there is.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic component taping device that does not require correction of lead deformation in electronic components to be used in advance.

The electronic component taping device of the present invention includes a recess into which an electronic component is inserted, which is provided at a predetermined interval on an outer circumferential surface, and a groove provided in the outer circumferential surface that is in contact with a plurality of leads of the electronic component. a taping drum that performs step rotation in one direction and stops for a predetermined time every time it rotates by an angle corresponding to the angle; and a mount that moves between the lead and the outer peripheral surface in contact with the outer peripheral surface in synchronization with the step rotation. a straightening punch having a plurality of pitch straightening grooves of a predetermined pitch into which each of the leads inserted into the groove is inserted while the taping drum is stopped; and a straightening punch rotatably supported on an axis parallel to the taping drum. an adhesive tape that is supplied to the taping drum via the roller and adheres to the backing paper with the lead sandwiched therebetween; and after the straightening punch is inserted, the adhesive tape moves toward the outer peripheral surface and presses the adhesive tape. Composed of a crimping punch.

According to the present invention, the distance between electronic components can be regulated to a predetermined dimension by inserting each lead into the pitch correction groove of the correction punch immediately before adhesively fixing the electronic component leads to the mount with adhesive tape. At the same time, the pitch dimension between the leads of each electronic component can be modified.

Next, the present invention will be explained with reference to the drawings.

FIG. 3 is a front view of one embodiment of the present invention, and FIG. 4 is a sectional view taken along line A-A' in FIG.

As shown in FIGS. 3 and 4, this embodiment has a recess 41 provided on the outer peripheral surface at a predetermined arrangement pitch a into which the main body of the electronic component 1 is inserted, and three recesses 41 of the electronic component 1. a taping drum 4 having a groove 42 provided on the outer peripheral surface in contact with the lead 11;
, a mount 2 that is wound in contact with the outer peripheral surface between the leads 11 and the outer peripheral surface, and a taping drum 4 having three pitch correction grooves 51 of a pitch equal to the pitch of the leads 11 of the electronic component 1 to be used. A straightening punch 5 capable of moving forward and backward toward the outer peripheral surface of the taping drum 4; a roller 3-1 rotatably supported on a shaft parallel to the taping drum 4; Adhesive tape 3 and mount 2 with adhesive tape 3 sandwiching lead 11 of electronic component 1.
A crimping punch 6 capable of moving forward and backward toward the outer circumferential surface of a taping drum 4 to which a crimping rubber 7 is fixed, a component supply section 8 that supplies electronic components 1 to the taping drum 4, and a mounting paper 2 wrapped around the crimping punch 6. roller 9
and a clawed roller 10 that guides the product to which electronic parts are taped to a packaging process.

The taping drum 4 is driven by a drive mechanism (not shown) to perform step rotation in the direction B of the arrow by repeatedly rotating the taping drum 4 by stopping the rotation for a predetermined time every time it rotates through an angle corresponding to the array pitch a.

Each time the taping drum 4 stops, the parts supply section 8
The main body of the electronic component 1 housed in the recess 4
1 and the lead 11 is placed on the taping drum 4.
is supplied so as to be in contact with the outer circumferential surface along the width direction of the outer circumferential surface. Also, the mount 2 fed out from the roller 9
The tape passes between the lead 11 and the outer circumferential surface, moves in contact with the outer circumferential surface in synchronization with the step rotation of the taping drum 4, and is fed into the packaging device by the clawed roller 10.

The stopping position of the taping drum 4 is set at the position shown in FIG. 3, where the electronic component 1 inserted into the recess 41 directly faces the straightening punch 5 and the crimping punch 6. When the taping drum 4 stops at the set position, the straightening punch 5 and the crimping punch 6 move forward in the direction of the arrow, and first each lead 11 of the electronic component 1 is inserted into the pitch straightening groove 51 of the straightening punch 5.

FIG. 5 is a partially cutaway front view of the pitch correction portion during lead insertion for explaining the operation of the embodiment of FIG. 1.

As shown in FIG. 5, the pitch correction groove 51 has a tapered tip opening, so that even if the lead 11 is deformed, the pitch correction groove 51 does not fit the lead 11 in each pitch correction groove 51.
is inserted reliably. By inserting the straightening punch 5 deeply into the groove 42, the pitch dimension of the lead 11 is corrected, and furthermore, the electronic component 1 is accurately positioned.

Subsequently, as shown in FIGS. 3 and 4, the adhesive tape 3 that is being supplied to the stop position of the taping drum 4 via the roller 3-1 is transferred to the pressure rubber 7 fixed to the tip of the pressure punch 6. Lead by 1
