Means for conveying a tape and a carrier-tape feeder having it}

The present invention relates to a tape transfer means and a carrier tape feeder having the same, and more particularly, to a tape transfer means and a carrier tape feeder having the same, which can transfer the tape more smoothly.

1 discloses a carrier tape feeder of Korean Laid-Open Patent Publication No. 2002-0047860. The carrier tape feeder includes a carrier conveying means 20 for conveying a carrier tape 4 having a carrier 2 and a tape 3 in which the integrated circuit chip 100 is accommodated, and a reverse rotation of the carrier conveying means. A reverse rotation preventing means 30 for preventing, a tape conveying means 40 for conveying the tape peeled off from the carrier to the outside, a driving means 50 for driving the carrier conveying means and the tape conveying means, and the tape in a peeled state Shutter means 70 for preventing the exposure of the integrated circuit chip and exposing the integrated circuit chip only when picked up by the pickup means 90 to prevent the integrated circuit chip stored in the carrier from escaping to the outside; and the driving means It is provided with a rotation angle detection means 80 for detecting the rotation angle of the.

The tape transfer means 40 is a worm wheel 63 for transmitting power from the driving means, a first gear 41 for transferring the tape by receiving power from the worm wheel, and meshes with the first gear to engage the tape. A second gear 42 to assist the transfer, a first lever 66 rotatably supporting the rotational shaft of the first gear, a first connected to the first lever to press the first gear toward the worm wheel side; A spring 66a, a second lever 67 rotatably supporting the rotational shaft of the second gear, and a second spring 67a connected to the second lever to press the second gear toward the first gear side. Equipped.

If the tape 3 is stretched, the tape may be caught in a portion of the shutter means 70, which hinders the operation of the shutter means. In order to prevent this, the tape conveying means 40 must convey the tape 3 in a stretched state. This is typically achieved by designing the tape feed rate at the tangential contact between the first gear 41 and the second gear 42 to be somewhat faster than the speed at which the tape 3 peels off the carrier tape 4. to be.

However, in the carrier tape feeder implemented as described above, the slip between the first gear 41 and the second gear 42 and the tape due to the difference of the speed of the feeding side and the feeding side of the same tape 3 ( slip) occurs. That is, the first gear 41 and the second gear 42 mesh with each other, but the tape is not conveyed. Such slip causes a strong vibration in the entire carrier tape feeder, so that the slip may not only be a problem in the durability of the carrier tape feeder, but may also cause a failure.

In particular, when such slip occurs when the shutter means is opened, the integrated circuit chip 100 accommodated in the carrier 2 is released from the carrier before being picked up by the pickup means 90 under the influence thereof. There is a problem that the stable supply of the integrated circuit chip, which is a basic function of the carrier tape, cannot be performed.

In addition, the tape 3 passed between the two gears 41 and 42 is folded in a zigzag form by the teeth of the gear. When the tape is folded in this way, the tape passing through the gears is loosened, so that the tape of the carrier tape feeder Touching the operating part, in particular the first gear and the second gears, may occur, which may interfere with the normal operation of the gear, causing failure or vibration.

The present invention solves the above problems, so that no slip occurs between the first gear 41 and the second gear 42 and the tape, so that vibration due to slip does not occur, and thus the carrier tape feeder. It is an object of the present invention to provide a tape conveying means and a carrier tape feeder having the same, which have a high durability, a low failure rate, and a stable supply of an integrated circuit chip.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 shows a carrier tape feeder with tape transfer means according to the invention.

The carrier tape feeder is a frame (1), a carrier conveying means 20 mounted on the frame to convey the carrier tape (4), a reverse rotation preventing means 30 to prevent the reverse rotation of the carrier conveying means, the carrier The tape conveying means 140 for conveying the tape peeled off from the outside, the driving means for driving the carrier conveying means and the tape conveying means 50, and the integrated circuit chip housed in the carrier while the tape is peeled off. To prevent the exposure of the integrated circuit chip and to expose the integrated circuit chip only when it is picked up by the pickup means 90, and the rotation angle detection means 80 for detecting the rotation angle of the driving means. ).

The carrier tape 4 is conveyed by the carrier conveying means 20, and the tape 3 is peeled off by the tape conveying means 140 before the carrier reaches the top of the carrier conveying means 20. Lose. As the tape 3 is peeled off, the integrated circuit chip 100 is transferred to the uppermost portion of the carrier transfer means 20 in a state where the integrated circuit chip 100 is accommodated in the accommodation space 2a of the carrier. 90) is picked up by adsorption or the like and moved to another position. The peeled tape 3 is transported out of the carrier tape feeder.

The frame 1 serves to support components other than the frame of the carrier tape feeder, and the components other than the frame are mounted directly or indirectly on the frame. The frame includes a first guide portion 1a and a second guide portion 1b, wherein the first guide portion serves to guide the tape 3 peeled off the carrier tape, and the second guide portion is exposed by peeling off the tape. The integrated circuit chip 100 is prevented from being separated from the storage space 2a of the carrier 2.

The carrier conveying means 20 is mounted on one side of the frame to convey the carrier tape 4, which has a sprocket 22 having teeth which fit into the conveying hole 2b of the carrier. And a first worm wheel 23 fixed to the sprocket. The sprocket 22 functions to convey the carrier intermittently. The first worm wheel 23 receives power from the driving motor 52 through the first worm gear 56 of the driving means 50 to be described later, and transmits the power to the sprocket.

The reverse rotation preventing means 30 is fixed to the first worm wheel by a spring 31 supported by a ratchet 31 and a support wall (not shown) having teeth inclined only in one direction. The stopper 32 is elastically pressurized and prevents the reverse rotation of the carrier transport means 20.

The tape transfer means 140 is spaced apart from the carrier transfer means 20 and rotatably installed on the other side of the frame, and transfers the tape 3 peeled off from the carrier 2 to the outside. The tape conveying means 140 includes a first gear unit 200, a second gear unit 300, and a gear unit pressurizing means. Hereinafter, the first gear unit, the second gear unit, and the gear unit pressurizing means will be described in detail with reference to FIGS. 4 to 8.

As shown in FIG. 4, the first gear unit 200 is rotatably supported on the frame by the first gear unit rotation shaft 270, and the transfer gear 220, the contact plate 240, and the first elasticity are provided. The member 230, the driving member 210, and the slip bush 250 are provided.

The transfer gear 220 has a ring-shaped side portion 221 and a circumferential portion 226 extending vertically from the circumferential end of the side portion and contacting the tape. The side portion 221 supports a first elastic member support portion 222 which supports the first end portion 231 of the first elastic member, which will be described later, and prevents it from moving laterally, and a contact plate, which will be described later, along the rotation axis of the transfer gear. An anti-rotation part accommodating part 221c is formed to move only and prevent rotation of the transfer gear. The circumferential portion 226 has teeth 221a formed on the outer circumferential surface thereof, and the teeth 221a mesh with the teeth 310a formed on the outer circumferential surface of the corresponding gear 310 of the second gear unit, which will be described later. Squeeze.

The contact plate 240 basically has a plate-shaped ring shape, and is accommodated in the circumferential portion of the transfer gear 220 so as to move along the rotation axis of the transfer gear. The contact plate is formed to be slidable with respect to the slip bush which contacts the other side while preventing the second end 232 of the first elastic member which contacts the one side from moving laterally. The contact plate may move along the rotation axis of the transfer gear according to the elastic contraction and expansion of the first elastic member, and the contact plate may not rotate with respect to the transfer gear, so that the contact plate may not be rotated. It is provided with a rotation preventing portion 241 having a corresponding shape.

The first elastic member 230 is the first end 231 and the contact plate 240 (contact plate 240, which is accommodated in the first elastic member support portion 222 formed on the side portion 221 of the transfer gear 220) In the case where the first slip washer 280 is interposed between the 240 and the slip bush 250, the first slip washer has a second end 232 in contact with the first slip washer. In this state, the first elastic member is interposed between the transfer gear and the contact plate in a compressed state, and FIG. 4 illustrates a coil spring as the first elastic member 230. According to the present invention, six arrangements are provided, but the present invention is not limited thereto, and other types of elastic members (for example, leaf springs) or other types of coil springs may be used according to specific conditions. Having a comparable diameter My coil spring may be employed.

The drive member 210 has the same rotation shaft as the transfer gear 220 and receives torque from a power source (not shown). The driving member 210 of the present embodiment is a gear having teeth formed on an outer circumferential surface thereof, but may be a pulley that receives power by a belt. The driving member is fixed to the slip bush 250 by the fastening member 252 which is not in contact with the transfer gear 220 and the contact plate 240, so that the driving member 210 and the slip bush 250 are The transfer gear 220 and the contact plate 240 may rotate (that is, slip). Whether the driving member 210 and the slip bush 250 rotate or rotate together with respect to the transfer gear 220 and the contact plate 240, torque, tape ( 3) the torque applied to the transfer gear 220, the frictional force between the transfer gear 220 and the drive member 210 (when the second slip washer 290 is interposed between the transfer gear and the drive member), 2 slip washers and frictional forces therebetween, and a first slip washer between the slip bushes 250 and the contact plate 240 (a first slip washer 280 is interposed between the slip bushes and the contact plates). Washers and friction between them), etc.). The friction force is determined by the elastic force of the first elastic member and the friction coefficient of the members in which friction occurs.

4 illustrates a first slip washer 280 and a second slip washer 290, which are not necessarily required to achieve the object of the present invention, but which the first gear unit 200 includes. The first slip washer 280 is manufactured to have a predetermined coefficient of friction and is interposed between the slip bush 250 and the contact plate 240. Similarly, the second slip washer 290 is also manufactured to have a predetermined coefficient of friction and is interposed between the transfer gear 220 and the driving member 210.

Even if the slip washers 280 and 290 are not present, the friction force may be properly processed by the surface in which the slip bush 250 and the contact plate 240 contact and the surface in which the transfer gear 220 and the driving member 210 contact each other. Although it can be adjusted, in this case, there is a disadvantage that the cost of replacing parts due to wear of the surfaces increases.

In the state in which the driving member and the transfer gear rotate together, the sum of the torque applied to the transfer gear 220 by the tape 3 and the torque applied to the drive member 210 from the drive means 50 is the When the torque in the opposite direction due to the minimum static frictional force of the frictional surfaces of the friction surfaces located between the driving member and the transmission gear is greater than the driving member and the transmission gear are relatively rotated (slip). As described above, in the state in which the driving member and the transfer gear are relatively rotated, the torque applied to the transfer gear 220 by the tape 3 and the torque applied to the drive member 210 from the drive means 50. When the sum is equal to or less than the torque in the opposite direction due to the frictional motion of the friction surface on which the slip occurs, the drive member and the transfer gear are rotated together again.

Even if the tape conveying means conveys the tape 3 at a speed higher than the speed at which the tape 3 is peeled off from the carrier 2, the tape between the conveying gear and the corresponding gear and the tape 3 in terms of torque and frictional force. If the first gear unit is configured such that slip occurs between the transfer gear 220 and the driving member 210 in the first gear unit before slip occurs, vibrations that may cause a failure may be prevented.

The slip bush 250 is disposed opposite the drive member 210 with the transfer gear 220 and the contact plate 240 interposed therebetween and is fixed to the drive member in the axial direction and the rotation direction. The slip bush is fixed to the driving member 210 by the fastening member 252, and the slip bush has a second fastening part 251 for receiving the fastening member 252, and the driving member 210. The first fastening part 211 receives the fastening member 252.

A slip bush cover 260 is mounted to the outside of the slip bush 250, and a rotation shaft of the first gear unit is fitted through the cover.

The second gear unit 300 includes a mating gear 310 and a mating gear cover 330 mounted on both sides of the mating gear.

The corresponding gear 310 is rotatably mounted to the frame by a second gear unit rotation shaft 340, and teeth 310a engaging with teeth 221a of the transfer gear are formed on an outer circumferential surface thereof. The mating gear cover 330 guides the tape to be transported between the mating gear and the transfer gear and not to depart therefrom.

When the teeth formed on the outer circumferential surface of the transfer gear circumferential portion 226 are continuously formed in the width direction of the outer circumferential surface, the second gear unit has the above-described configuration, and as such a configuration, at least partially achieves the object of the present invention. can do. However, in order to maximize the function and effect of the tape conveying means according to the present invention, a groove 221b is formed in the longitudinal direction on the outer circumferential surface of the circumferential portion 226 of the first gear unit, and the second gear unit corresponds thereto. It is preferable to configure it. Specifically, as shown in FIG. 5, the second gear unit corresponding to the first gear unit includes the corresponding gear cover 330, the corresponding gear 310, the corresponding washers 320A and 320B, and the corresponding gear 310. And a corresponding gear cover 330 in turn. These are all fixed by the fastening member 331 so as not to rotate relative to each other.

The corresponding washers 320A and 320B interposed between the corresponding gears 310 have a shape accommodated in the groove 221b of the transfer gear 220. As the peripheral end of the corresponding washer is inserted into the groove 221b, a predetermined pattern is formed on the tape 3 transferred between them by the transfer gear 220 and the corresponding gear 310. Since it is not easily folded or has a small amount of folding, it does not interfere with the operation of the tape conveying means or other operating portions of the carrier tape feeder having the same.

When the corresponding washer 320A having the smooth circumferential end as shown in FIG. 5 is interposed between the corresponding gears, the teeth 221a of the transfer gear and the teeth 310a of the corresponding gear are mainly tape. (3) and the groove 221b and the corresponding washer 320A of the transfer gear serve to form the pattern on the tape.

In the case where the corresponding washer 320B having the circumferential end with the acute protrusion as shown in FIG. 6 is interposed between the corresponding gears, the teeth 221a of the transfer gear and the teeth 310a of the corresponding gear. Rather, the protrusions contribute more to the conveyance of the tape. This is because the projection moves as if the surface of the tape 3 is taken down as it rotates. According to the applicant's experiment, the second gear unit having the corresponding washer 320B having the acute angled protrusion at the circumferential end thereof prevents the tape from slipping than the second gear unit having the corresponding washer 320A having the circumferential end smoothly. And it appeared to be excellent in the effect of the operation prevention prevention of the drive part by folding.
