Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a highly reliable taped component conveying device that can reliably convey taped components.

Recently, when various electronic components are incorporated into a printed wiring board, the electronic components are taped so that they can be continuously supplied to an automatic insertion machine.

That is, as shown in FIG.
The lead wires 1 of the electronic component 2 drawn out are bonded and held at regular intervals by a band-shaped mount and tape 3, and conveyance holes 4 are formed at a constant pitch in the mount and the tape 3 to form a taped component.

FIG. 2 shows a recently developed conveying device for such taped parts.

In FIG. 2, a groove 6 is formed in the fixed block 5 in the longitudinal direction of the center of the conveying surface of the taped component, and a recessed notch 7 is provided in the middle of the sliding surface.

A slide shaft 8 is fixed to this recessed notch 7, and a slide block 9 that slides while being guided by this slide shaft 8 is disposed. 10 is landed and always biases the slide block 9 in one direction.

A downward projecting piece 11 is provided on the lower surface of the other end of the slide block 9, which is different from the one end where the compression spring 10 is provided, and a rod 13 of the cylinder 12 is arranged in correspondence with this projecting piece 11. .

Further, a groove 14 similar to that of the fixed block 5 is provided on the conveyance surface of the taping parts of this slide block 9, and one end is connected to the support shafts 15 to 18 in the grooves 6 and 14, and the conveyance surface of the other end Levers 27-30 are disposed on the sides thereof, and have springs 23-26 on the other end for pushing the feed pins 19-22 onto the conveying surface.

A taping part shown in FIG. 1 is interposed on the conveying surface of the fixed block 5, and a groove 31 is formed in the central longitudinal direction of the conveying surface through this taping part. A plate 32 is arranged, and the fixed block 5 and the backing plate 32 guide the mount and the tape 3.

The feed pins 19 to 22 are made by cutting diagonally a cylindrical piece having a diameter approximately equal to the diameter of the conveyance hole 4 from the end of the upper surface to the end of the lower surface, and connecting the lower surface to the levers 27 to 30, so that the feed pins 19 to 22 are arranged in the feeding direction. The structure has an engaging portion on both sides.

With this configuration, when the protruding piece 11 of the slide block 9 is pushed by the rod 13 of the cylinder 12 and the slide block 9 is guided by the slide shaft 8 and slides in the direction of the arrow against the compression spring 10, this Feed pin 20.2 of levers 28, 29 provided in groove 14 of slide block 9
1 fits into the transport hole 4 of the mount and tape 3 as shown in FIG.
The taping part is sent in such a way that the other end of 29 is in pressure contact with the mount and the tape 3.

This amount of feed corresponds to the sliding stroke of the slide block 9 within the concave notch 7 of the fixed block 5, and this is made equal to the pitch of the conveyance holes 4 formed in the backing paper and the tape 3.

When the rod 13 of the cylinder 12 returns to its original position after sliding by this sliding stroke, the slide block 9 is automatically returned to its sliding position by the compression spring 10.

At this time, since the sliding return side of the levers 28 and 29 that were fitted into the transport holes 4 of the backing paper and tape 3 and the sliding return side of the levers 21 have a lower surface and a tapered surface, there is no hooking part and the springs 24 and 25 Even if the levers 28 and 29 are in pressure contact with the mount and the tape 3, the feed pins 20 and 21 of the levers 28 and 29 come out of the conveyance hole 4 as shown in FIG. 4 and return to a sliding state.

At this time, the taping parts fit into the feed pins 19, 22 of the levers 27, 30 provided in the grooves 6 of the fixed block 5, and the transport holes 4 of the tag 3 fit into the mount and are returned together with the slide block 9 in the opposite direction to the feed direction. is prevented.

FIG. 5 shows the state before the taping part is transported, and all the feed pins 19 to 22 are fitted into the transport hole 4, and the taping part is transported normally and the slide block 9 is slid by the sliding stroke. The state when the movement is finished is shown in FIG. 6, in which all the feed pins 19 to 22 are fitted into the conveyance hole 4.

In the conveyance device with such a configuration, since the feed pin 19 of the lever 27 of the fixed block 5 is located on the forward side in the conveyance direction of the feed pin 20 of the lever 28 of the slide block 9, the electronic component 2 bends the backing paper and the tape 3. When the tape 3 is placed in a box and the backing paper and tape 3 have a crease 33, when the crease 33 comes between the lever 28 of the slide block 9 and the lever 270 of the fixed block 5, as shown in FIG. In addition, since the lever 27 is pressed against the mount and the tape 3 by the spring 23 of the fixed block 5, this creates resistance, and the mount and the tape 3 buckle at the fold line 330.

When buckled, the distance between the conveying holes 4 on both sides of the buckled area becomes shorter than before buckling.

As a result, when the taping part is transported by the sliding stroke by the levers 28 and 29 of the slide block 9, the transport hole 4 that was fitted into the feed pin 19 of the lever 27 of the fixed block 5 is moved to the position where the feed pin is. to,
I can't reach it.

In this case, it is no longer possible to prevent the taping component from being returned together with the slide block 9 in the opposite direction to the feeding direction, and the taping component is returned together with the slide block 9 in the opposite direction. It is no longer possible to carry out sliding movements and transport the taped parts.

Therefore, if the spring 23 that presses the lever 27 against the mount and tape 3 is weakened, the buckling will be reduced, but at the same time the lever 270, which had the function of stopping the mount and tape 3 when the slide block 9 stops, Mount, tape 3
The force that presses the tape 3 is also reduced, and the distance from when the slide block 9 stops to when the mount and tape 3 stop becomes longer.

Hereinafter, the movement of the mount and tape 3 in the forward direction in the transport direction after the slide block 9 has stopped will be referred to as forward running.

In addition, since the drive is based on the cylinder 12, the slide block 9 suddenly stops, so if the spring is weakened, the forward running of the backing paper and tape 3 when the slide block 9 stops will become even larger, and the flow of the conveyor hole 4 will increase. In tape 3, a mount with a pitch of 12.7 mm, there are two tapes.

As described above, the conventional taped component conveying device has the drawback that buckling and running ahead occur, resulting in low reliability for accurate conveyance at a constant pitch.

The present invention eliminates the drawbacks of the prior art as described above.

Embodiments of the present invention will be described below with reference to FIGS. 8 to 13.

It should be noted that the present invention is an improvement of the above-mentioned conventional conveyance device, and the same parts are given the same reference numerals and explanations will be omitted.

As shown in FIG. 8, the position of the support shaft 16 of the lever 28 on the front side of the slide block 9 in the transport direction is different from that of the other three support shafts 1.
5, 17, and 18, and the length of the lever 28 is longer, so that it is installed so that it passes behind the lever 27 on the front side in the transport direction among the levers attached to the fixed block 5. It is being

Further, the feed pin 20 attached to the lever 28 that slides back and forth is attached to the front side in the conveyance direction rather than the feed pin 19 on the front side of the fixed block 5 in the conveyance direction.

Further, the lever 27 has a bifurcated long end on both sides, and the tip of the lever 28 is fitted between them.

Furthermore, as shown in FIG. 9, two guide plates 48 are attached to the upper and lower component transport surfaces of the feed pins 19 to 22.

Further, as shown in FIG. 10, a lever 35 shaped like a "<<" and rotating around a fulcrum shaft 34 is mounted on the plate 36.

A cylinder 37 is connected to one end of the lever 35 by a pin 38, a ring 39 is connected to the other end by a pin 40, a rod 42 is connected to the other end of the ring 39 by a pin 41, and a bearing 43 is rod 4
2, the rod 42 pushes the protrusion 11.

FIG. 11 shows the above-mentioned toggle mechanism in a state before the rod 42 pushes the protrusion 11.

FIG. 12 shows a state in which the cylinder 37 is operated and the rod 42 also extends fully in the conveying direction.

As shown in FIG. 12, since the fulcrum shaft 34 and pins 40, 41 are installed so that they are aligned in a straight line when the cylinder 37 comes out completely, the speed of the rod 42 decreases before the cylinder 37 comes out completely. , when the cylinder 37 comes out completely, the speed of the rod 42 becomes zero.

Furthermore, since the lever 28 of the slide block 9 is located farther from the conveying surface, the conventional compression spring 10 cannot be attached, so a compression spring 45 is attached in its place as follows.

As shown in FIG. 13, the slide shaft 8 is fixed to a slide block 9 and slides in a hole 44 formed in the fixed block 5.

Then, the front half of the slide shaft 8 in the transport direction is made hollow, the compression spring 45 is inserted therein, and the hole 4 of the fixed block 5 is
A spring holder 46 and a spring holder 47 are attached to the spring holder 4 to always bias the slide block 9 in one direction.

With this configuration, when the backing paper and tape 3 are transported, the feeding pin 20 that slides back and forth is attached to the forefront in the transport direction, so the backing paper and tape 3 do not buckle when being transported.

Furthermore, when the sliding return occurs, the lever 27 is pressed against the backing paper and the tape 3 by the spring 24 of the fixed block 5 on both sides of the feed pin 200 of the lever 28 that slides back and forth, so there may be creases in the backing paper and the tape. However, it does not buckle.

Furthermore, by attaching the guide plate 48, the mount and tape 3 no longer come into direct contact with the corners of the fly block 9 and the fixed block 50.

Furthermore, when the rod 42 pushes the protruding piece 11, the slide block 9 moves in the transport direction.
The speed decreases as the protrusion 11 is pushed, and when it is pushed all the way, the speed becomes zero, so even if the springs 23 to 26
Even if it is weak, it can prevent the mount and tape 3 from running ahead.

As described above, the present invention includes a slide block that slides back and forth within the concave portion of the fixed block guided by a slide shaft and a guide plate, and has an engaging portion in the conveying direction of the taped component conveying surface of the fixed block and the slide block. rice cake,
A lever with a feed pin that does not have an engaging part in the opposite direction is provided, and the mount of the taping part and the backing plate that guides the tape are placed opposite and adjacent to the guide plate, and the recess at the tip of the lever is supported by the slide block. When the lever attached to the shaft is positioned and the slide block is reciprocated by a toggle mechanism consisting of an air cylinder, lever, link, pin, and rod, and the taping part is fed with a constant stroke,
Taped electronic components can be transported and positioned with high reliability without buckling the mount or tape or overfeeding.
