Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling cutter, and more particularly, to a rolling cutter for cutting each lead of a radial taping component and separating the component into individual components.

[0002]

2. Description of the Related Art A conventional rolling cutter cuts each lead of a radial taping component to a predetermined length and separates the component into individual components. Then, the worker inserts the leads of the separated components into the lead insertion holes provided on the printed circuit board and performs soldering.

[0003]

In the above-mentioned conventional rolling cutter, each lead is merely cut and separated into parts. Therefore, the leads of these parts are used for the leads arranged on a printed circuit board. The parts were easy to fall down just by inserting them through the insertion holes. Therefore, it is necessary to perform soldering while supporting the component upright on the printed circuit board, which is troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a rolling cutter which can save the trouble of supporting each separated component to stand upright on a printed circuit board.

[0005]

In order to achieve the above object, the invention according to claim 1 has a base, a shaft core rotatably supported by the base, and a tape portion of a radial taping component held therebetween. A pair of feed rollers that can be fed out, a disk-shaped cutter portion fixed to the rotation shaft of each feed roller, the peripheral portions of which are adjacent to each other, and cut the lead of the radial taping component, and the rotation of each of the feed rollers A configuration is provided that includes a pair of concave and convex rollers that are fixed to a shaft, sandwich a lead of the radial taping component, and form a bent portion that can be engaged with a printed circuit board.

According to the first aspect of the present invention, when a pair of feed rollers rotatably supported on a base with a shaft core sandwich and feed out a tape portion of a radial taping component, each of the feed rollers is pulled out. A disk-shaped cutter portion fixed to the rotation shaft of the feed roller and having a peripheral portion adjacent to each other cuts the lead of the radial taping component, and a pair of concave and convex rollers fixed to the respective rotation shafts of the feed roller are radially separated. A bent portion capable of holding the lead of the taping component and engaging with the printed board is formed. When the worker mounts the separated component on the printed circuit board, the bent portion is engaged with the lead insertion hole of the printed circuit board, so that the component is hard to fall.

[0007] The cutter section may have any structure as long as it can cut the lead of the radial taping component fed by the feed roller. As an example of the arrangement of the cutter section, the invention according to claim 2 is the rolling cutter according to claim 1, wherein the cutter section is arranged between the feed roller and the uneven roller. . In the invention according to claim 2 configured as described above, the cutter section cuts the lead of the radial taping component between the feed roller and the uneven roller. Therefore, the lead of each component is cut at the tape portion side, and the lead remaining on this component side is bent into a predetermined shape.

The position and shape of the cutter portion can be changed as appropriate according to the number and shape of the lead wires to be cut. This includes a case where a plurality of feed rollers are provided and a case where unevenness is formed on the cutter surface. It is. The concave and convex roller may be any shape as long as the bent portion formed when the lead is sandwiched can be formed into a shape that can be engaged with the printed circuit board. As an example of the shape of the uneven roller, the invention according to claim 3 is as follows.
The rolling cutter according to any one of claims 1 and 2, wherein the concave and convex rollers are configured to form bent portions that are directed in mutually opposite directions in a plane in which the leads of the radial taping component are arranged.

[0009] In the invention according to claim 3 configured as described above, the uneven roller bends the leads of the radial taping component in directions opposite to each other in a plane in which the leads are arranged. That is, when one lead is bent to the other lead side, the other lead is bent to the one lead side, and when one lead is bent to the opposite side to the other lead, A bent portion is formed so that the other lead is bent to the opposite side to the one lead.

[0010] When the leads are bent in opposite directions in the plane in which the leads are arranged in this manner, the posture of each component is stable when the leads are engaged with the printed circuit board. However, the bending direction of the leads does not necessarily need to be limited as described above, and from the viewpoint of forming the bent portions of the original leads, each of the leads depends on the shape of the lead insertion hole in the printed circuit board to be engaged. The case where the bending direction or the bending shape is changed is also included.

The feed roller is only required to be able to hold and feed out the tape portion of the radial taping component. An example of the shape of the feed roller for preventing a shift in the holding position of the tape portion is the invention according to claim 4. In the rolling cutter according to any one of claims 1 to 3, the feed roller engages with a synchronous hole provided at a predetermined interval in a tape portion of the radial taping component while performing positioning. It has a configuration with a feeding claw.

[0012] In the invention according to claim 4 configured as described above, the claw provided on the feed roller engages with a synchronization hole provided at a predetermined interval in a tape portion of the radial taping component and is positioned at the same position. Send together. Therefore, the radial taping component is always fed out while correcting the position based on the position of the synchronization hole.

[0013]

As described above, according to the present invention, when a lead of a radial taping component is cut and separated into individual components, a bent portion is formed in the lead. By engaging with the hole, it is possible to provide a rolling cutter capable of eliminating the trouble of supporting the component upright on the printed circuit board.

According to the second aspect of the present invention, the lead can be cut between the tape portion and the bent portion formed on the lead. Furthermore, according to the third aspect of the present invention, since each lead is bent in the direction opposite to each other in the plane in which the leads are arranged, when the bent portion of the lead is engaged with the lead insertion hole in the printed circuit board, The posture of the parts can be stabilized. Further, according to the fourth aspect of the present invention, the radial taping component can be extended while correcting the holding position.

[0015]

It has. On the other hand, a reel-shaped drum 70 is arranged behind the rolling cutter 10 so that a radial taping component 80 can be supplied. The rolling cutter 10 pulls a tape portion 84 of the radial taping component 80 while pulling a lead 82. Is bent at a predetermined position while the lead 82 is bent into a predetermined shape.

The radial taping component 80
Is the lead 8 of each capacitor as shown in FIG.
2 is sandwiched between two tapes to support capacitors at equal intervals. In the present embodiment, the radial taping component 80 of the capacitor is used. However, the component is not necessarily a capacitor, and may be a radial taping component that supports another component such as a resistor or a transistor. The pedestal 20 is formed of a thin box, and has columns 30 and 30 erected on its upper surface. The columns 30 and 30 are formed of two trapezoidal plate-shaped members, which are arranged in parallel. During this time, the rotating shafts of the upper and lower rollers 40 and 60 are rotatably supported. In this sense, the pedestal 20 and the posts 30, 3
0 constitutes a base. Since the base only needs to be able to rotatably support at least the rotating shafts of the upper roller 40 and the lower roller 60, the configuration can be appropriately changed depending on the shape and size of these rollers.

FIG. 3 shows a section adjacent to the upper roller 40 and the lower roller 60 in a vertical section. For convenience of explanation, the right side of the paper is referred to as the right side, and the near side of the paper is referred to as the front. However, the direction can be appropriately changed at the place of use. Upper roller 40 and lower roller 6
0, the upper holding portion 42 and the lower holding portion 62 which hold and feed out the tape portion 84 from the right side, and the lead 82 of the capacitor.
Cutter blades 44 and lower cutter blades 64 for cutting the blades, the convex portions 46 and the concave portions 6 forming the bent portions 82a in the leads 82.
When the rollers 40 and 60 are rotated in opposite directions in the front-rear direction, the radial taping component 80 is nipped and fed, and the leads 8 are provided.
2 is cut at a predetermined position, and the lead 82 of each capacitor is bent into a predetermined shape.

The upper holding portion 42 and the lower holding portion 62 are constituted by arranging rubber non-slip members 42a, 62a on the right peripheral edge of the upper roller 40 and the lower roller 60, respectively. 62a presses and clamps the tape portion 84, and when the rollers 40 and 60 are rotated in the front-rear direction, the tape portion 84 is fed forward. In this sense, the two rollers 40 and 60 and the upper and lower holding portions 42 and 62
Construct a feed roller. Note that these anti-slip members 4
The upper and lower rollers 4a and 2a have an appropriate thickness.
It is configured to protrude more radially than other portions of the peripheral portion of 0, 60, and press the protruding portion to clamp the tape portion 84. Therefore, when the tape portion 84 is pinched, the tape position does not shift and slip. Of course, in addition to such a configuration, for example,
For a slippery material such as a metal surface, a grid-like uneven shape may be formed on the surface to prevent slippage.

The upper and lower holding portions 42 and 62 do not necessarily have to be only one pair. For example, a radial taping component 80 having two tape portions 84 may be used.
When holding and feeding out, two pairs of upper and lower holding portions 42,
62 may be provided on both sides. Further, the shape of the upper and lower holding portions 42 and 62 is not limited to the above-described configuration, and a pair of endless belts that rotate coaxially with the upper and lower rollers 40 and 60 in conjunction with the rotation of the handle 50 are provided on each roller. The tape portion 84 may be disposed between the endless belts and fed out.

Synchronous holes 86 are formed at regular intervals in the tape portion 84 in order to synchronize the feed, and a claw 62b having a tapered tip at the lower holding portion 62 in accordance with the interval of the synchronous holes 86. Are arranged at predetermined intervals. Correspondingly, concave portions 42b capable of accommodating the claws 62b are formed in the upper holding portion 42 at the same intervals. With this configuration, when the upper and lower rollers 40 and 60 are rotated,
The hook 62b is engaged with the synchronization hole 86 of the tape portion 84, and the feed timing of each capacitor is adjusted.

The upper cutter blade 44 is formed in a disk shape whose diameter is slightly larger than the diameter of the upper roller 40, and is fixed coaxially with the upper roller 40. The lower cutter blade 64 is formed in a disk shape having the same diameter as the lower roller 60, and is fixed coaxially with the lower roller 60. These upper and lower cutter blades 44 and 64 are adjacent to each other so that the side surfaces of the peripheral edge portions are in contact with each other. The lower roller 60 is provided with a cutter groove 65 that can accommodate an end of the upper cutter blade 44. With this configuration, the upper and lower rollers 4
When 0 and 60 are rotated in opposite directions, the peripheral edge of the upper cutter blade 44 and the peripheral edge of the lower cutter blade 64 are rotated while being pressed against each other, and the lead of the capacitor which is fed while being sandwiched by the tape portion 84 is fed. Cut 82. In this sense, the upper cutter blade 44, the lower cutter blade 64, and the cutter groove 65 constitute a cutter unit.

The upper and lower cutter blades 44 and 64 may be provided as a pair, but when cutting the lead of a resistor in which two leads project in opposite directions, the resistor body is sandwiched. The upper and lower cutter blades 44 on both sides respectively,
64 may be arranged. The convex portion 46 and the concave portion 66 are disposed facing each other on the left peripheral surface of the upper and lower rollers 40 and 60, and face each other when the upper and lower rollers 40 and 60 rotate.
2 is bent into a shape corresponding to the peripheral portion of the convex portion 46 and the concave portion 66. In this sense, the convex portion 46 and the concave portion 66 constitute an uneven roller.

At this time, the clamped lead 82 is pushed into the concave portion 66 by the convex portion 46 to form a bent portion 82a protruding toward the rotation axis direction of the lower roller 60. The formation of the bent portion 82a is performed according to the above-described lead 82.
Is performed at the same time as the disconnection, so that each capacitor is separated in a state as shown in FIG. When each of the separated capacitors is mounted on the printed board 90, as shown in FIG. 5, when the lead 82 is inserted into the lead insertion hole 92 provided on the printed board 90, the bent portion 82a is engaged. For this reason, the capacitor hardly falls down, and when soldering the lead 82 to the printed circuit board 90, it is not necessary to support the capacitor so as to stand upright.

In the concavo-convex roller according to this embodiment, as described above, the two leads 8 in one capacitor are used.
2 and 82 are bent in the same direction, but it is sufficient if at least the leads 82 and 82 can be engaged with the lead insertion holes 92 of the printed circuit board 90. As described above, the leads 82 and 82 are not necessarily in the same direction. Need not be bent. For example, the leads 82 may be bent in different directions, and this case will be specifically described. As shown in FIG. 6, instead of the convex portion 46, tapered convex portions 47a and 47b are formed on the peripheral edge of the upper roller 40, and instead of the concave portion 66, these concave portions 47a and 47b can be respectively accommodated. Lower rollers 6a and 67b
0 is formed on the periphery. A lateral groove for holding the lead 82 is formed on the peripheral surface of the lower roller 60, and the lead 82 supplied to the claw 62 at a predetermined timing is accommodated in the lateral groove.

FIGS. 7A to 7C show a state in which the lead 82 is bent by the convex portion 47a and the concave portion 67a. When the upper and lower rollers 40 and 60 are rotated to retract the radial taping component 80, the lead 82 crosses the recess 67a while entering the lateral groove. Here, the tapered tip starts to enter the recess 67a from the front side with respect to the lead 82, and enters the depth. Then, the tapered surface comes into contact with the lead 82 and is bent obliquely rearward. On the other hand, the same operation is performed with respect to the convex portion 47b and the concave portion 67b by reversing the front and rear.
It can be bent obliquely forward inside. Then, in the capacitor separated from the radial taping component 80, each lead 82 as shown in FIG. When this capacitor is inserted into the lead insertion hole 92 of the printed circuit board 90, the leads 82 are bent in the directions facing each other, so that they are stably engaged by the repulsive force of each other. Therefore, the posture of the capacitor is stabilized.

Next, the operation of separating each condenser from the radial taping component 80 by the rolling cutter 10 will be described. The distal end of the radial taping component 80 wound around the drum 70 is pulled out, the synchronization hole 86 is hooked on the claw 62b of the lower roller 60, and the handle 50 is rotated. Then, the radial taping component 80 is sandwiched between the upper and lower rollers 40 and 60. That is, the tape portion 84 of the radial taping component 80 is
When the upper and lower rollers 40 and 60 are further rotated, the lead 82 is cut while being drawn between the peripheral edge of the upper cutter blade 44 and the peripheral edge of the lower cutter blade 64. Needless to say, since the lead 82 simultaneously passes between the convex portion 46 and the concave portion 66, the leading end portion of the convex portion 46 pushes an intermediate portion of the lead 82 into the concave portion 66 to form a bent portion 82a. Then, each capacitor can be separated in a state as shown in FIG.

When the lead 82 of the separated capacitor is inserted into the lead insertion hole 92 provided on the printed circuit board 90 from the tip, as shown in FIG. 5, it can be engaged by the formed bent portion 82a. it can. Therefore, this capacitor stands upright on the printed circuit board 90 and does not easily fall down, and can be soldered without supporting the capacitor. As described above, the tape portion 84 of the radial taping component 80 is used as the upper holding portion 4 as a feed roller.
2 and the lower holding portion 62, the lead 82 is cut between the upper cutter blade 44 and the lower cutter blade 64 as a cutter portion, and at the same time, the capacitor-side lead 82 is cut by the convex portion 46 and the concave portion 66. In order to separate the capacitors while forming a bent portion 82a having a predetermined shape by being sandwiched, the lead insertion hole 9 of the printed circuit board 90 is formed at the bent portion 82a.
2 can be engaged.
