Description

The present invention relates to a setting method and a setting device for a splicing position of a carrier tape.

In general, in component mounters, a carrier tape holding a plurality of electronic components at regular intervals is wound around a reel, and the carrier tape is fixed by driving a sprocket that engages a feed hole drilled in the carrier tape. The electronic components are sequentially supplied to the component supply position. The electronic component supplied to the component supply position is sucked by the suction nozzle and mounted on the circuit board.

In this type of component mounter, when the remaining amount of electronic components held on one reel is reduced (eliminated), the same type of electronic components is held at the end of the carrier tape when the remaining amount is reduced. A so-called splicing is performed in which a starting end portion of a carrier tape wound around another reel is connected by a splicing tape or the like. Such a splicing device is described in Patent Document 1, for example.

JP2013-161908A

Many of the carrier tapes handled by this type of splicing apparatus include a carrier tape having a component storage cavity pitch of 2 mm and a carrier tape of 4 mm in order to store electronic components having different component sizes. In this case, both the carrier tape having a cavity pitch of 2 mm and the carrier tape having a pitch of 4 mm have the same pitch of the feed holes engaged with the sprocket.

In general, the carrier tape TcA1 (TcA2) having a cavity pitch of 4 mm has the same interval (PcA) as the pitch of the feed holes HcA between the feed holes HcA, as shown in FIG. Is arranged. On the other hand, in the carrier tape TcB1 (TcB2) having a cavity pitch of 2 mm, as shown in FIG. 6B, the cavities CtB are arranged at an interval (PcB) that is half the pitch of the feed holes HcB, and Every other cavity CtB is arranged to coincide with the center of the feed hole HcB.

When splicing between the splicing positions of two carrier tapes, the splicing position is usually set to a position that avoids the cavity (a position that does not cross the cavity). In many cases, the center position between the cavities is the splicing position. Is done. Therefore, normally, in the carrier tape TcA having a cavity pitch of 4 mm, as shown in FIG. 6A, the center of the feed hole HcA is set to the splicing position SP1, and the carrier tape TcB having a cavity pitch of 2 mm is used. As shown in FIG. 6B, the intermediate position between the cavities is set as the splicing position SP1.

For this reason, conventionally, the splicing position of the carrier tape differs depending on the pitch of the cavity. Accordingly, when performing splicing manually, the operator must visually determine the cavity pitch and set the splicing position. For this reason, it is troublesome and a human error may occur, resulting in a decrease in workability.

In addition, when splicing automatically, it is possible to determine the pitch of the cavities using a sensor that detects the cavities and set the splicing position, but it is difficult to detect the cavities and parts in the carrier tape. There are some cases, and there is a case where it is required to cope with such a carrier tape.

The present invention has been made to solve the above-described problems, and provides a splicing position setting method and setting that can easily set a splicing position on the basis of a common feed hole regardless of the pitch of the cavity. It is the purpose.

In order to solve the above-mentioned problem, the invention according to claim 1 is characterized in that feed holes and component storage cavities are arranged at a constant pitch interval, the pitch intervals of the feed holes are the same, and the pitch intervals of the cavities are the same. A splicing position setting device for at least two types of carrier tapes different from each other, wherein the unnecessary portions at the tips of the first and second carrier tapes of the same type of the two types of carrier tapes are cut into first and second tapes. First and second cutting devices for cutting in a direction perpendicular to the longitudinal direction of the first and second carrier tapes, and first and second transporting in opposite directions toward the first and second tape cutting positions 2 tape feeders and the center position of the feed holes of the first and second carrier tapes conveyed by the first and second tape feeders Are detected at the first and second feed hole detection positions, respectively, and the center position of the feed hole of the first carrier tape is detected by the first feed hole detection device. The first tape feeding device is controlled to be positioned at the first tape cutting position, and the center position of the feeding hole of the second carrier tape is detected by the second feeding hole detecting device; A control device that controls the second tape feeding device and positions the second tape feeding device at the second tape cutting position, and a distance from the first feeding hole detection position to the first tape cutting position, and the second feeding hole. The distance from the detection position to the second tape cutting position is changed by the diameter dimension of the feed hole, and the feeding of the first carrier tape controlled by the first tape feeding device is performed. And a vertical tangent position that contacts the tangential direction of the feed hole of the first and second carrier tapes by setting the same feed amount of the second carrier tape controlled by the second tape feeder. As a position, a splicing position setting device for positioning at the first and second tape cutting positions, respectively.

According to the invention according to the above-described claims, it is only necessary to set the vertical tangent position of the feed hole as the splicing position regardless of the pitch of the cavity, so it is not necessary to set the splicing position according to the type of the carrier tape. . Accordingly, since a mechanism for discriminating the type of carrier tape, the pitch of the cavity, and the like can be eliminated, the configuration of the splicing device can be simplified and the manufacturing cost can be reduced.

FIG. 3 is a view showing two types of carrier tapes according to the embodiment of the present invention and having different pitch intervals of component storage cavities. It is a figure which shows the state which splices two types of carrier tapes. It is a figure which shows the state which positioned the two carrier tapes by the positioning pin at the time of splicing. It is the schematic which shows the tape feeder of a splicing apparatus. It is explanatory drawing which sets the splicing position of two carrier tapes. It is a figure which shows the state which splics two types of conventional carrier tapes.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing two types of carrier tapes TcA and TcB in which the pitch intervals of the feed holes HcA and HcB are the same and the pitch intervals of the component storage cavities CtA and CtB are different.

In one carrier tape TcA shown in FIG. 1A, for example, the pitch PhA of the feed holes HcA is 4 mm, and the pitch PcA of the cavities CtA is 4 mm, which is the same as the pitch PhA of the feed holes HcA. In the other carrier tape TcB shown in FIG. 1B, for example, the pitch PhB of the feed holes HcB is 4 mm, and the pitch PcB of the cavities CtB is 2 mm. The hole diameters of the feed holes HcA and HcB are both 1.5 mm.

That is, in one carrier tape TcA, the cavities CtA are arranged at the same interval as the pitch of the feed holes HcA, and are arranged between the feed holes HcA. On the other hand, in the other carrier tape TcB, the cavities CtB are arranged at intervals of 1/2 of the pitch of the feed holes HcB, and every other cavity CtB coincides with the center position of the feed holes HcB. Is arranged.

Therefore, in the present embodiment, regardless of whether the pitch of the cavities CtA and CtB is 4 mm or 2 mm, the two types of carrier tapes TcA and TcB are placed at the same position without crossing (cutting) the cavities CtA and CtB. As shown in FIGS. 2A and 2B, the splicing position SP1 that can be cut was set to a vertical tangent position of the feed holes HcA and HcB. That is, the tangent lines of the feed holes HcA and HcB perpendicular to the longitudinal direction of the carrier tapes TcA and TcB are set as the splicing positions SP1 of the carrier tapes TcA and TcB.

Here, as for the standard size of the cavity provided by the parts manufacturer, when the pitch of the cavity CtA is 4 mm, the maximum BOAO is “3216” (vertical dimension 32 mm × horizontal dimension 16 mm). On the other hand, when the pitch of the cavity CtB is 2 mm, BOAO is “1608” (vertical dimension 16 mm × horizontal dimension 0.8 mm) at the maximum.

Accordingly, when the vertical tangential position of the feed holes HcA and HcB is the splicing position SP1, in the case of the carrier tape TcA where the pitch of the cavity CtA is 4 mm and the BOAO is “3216”, the minimum between the splicing position SP1 and the end of the cavity CtA The distance d0 is 0.5 mm. That is, since the distance between the feed hole HcA and the cavity CtA is 2 mm and the radius of the feed hole HcA is 1.5 mm, the minimum distance d0 between the splicing position SP1 and the end of the cavity Ct is 0.5 mm (d0 = 2mm-1.5mm).

Similarly, in the case of the carrier tape TcB where the pitch of the cavity CtB is 2 mm and the BOAO is “1608”, the minimum distance d0 between the splicing position SP1 and the end of the cavity CtB is 0.35 mm. That is, since the diameter of the feed hole HcB is 1.5 mm and the width dimension of the cavity CtB is 0.8 mm, the minimum distance d0 between the splicing position SP1 and the end of the cavity CtB is 0.35 mm (d0 = 1.5 mm). /2-0.8mm/2).

In this way, the distance d0 between the splicing position SP1 and the end of the cavity CtA is 0.2 mm or more that can be manually cut even if the maximum dimensions of the cavities CtA and CtB of the two types of carrier tapes TcA and TcB are taken into consideration. Can be secured. For this reason, the operator can easily cut the carrier tapes TcA and TcB at the vertical tangent positions (splicing positions) SP1 of the feed holes HcA and HcB.

According to the above-described embodiment, unlike the prior art, it is not necessary for the operator to visually determine the pitch of the cavities CtA and CtB and to set the splicing position SP1 separately, so that the types of carrier tapes TcA and TcB Regardless, since it is only necessary to cut at the vertical tangent position SP1 of the common feed holes HcA and HcB, it is possible to prevent the occurrence of a human error and to significantly improve workability.

Note that two carrier tapes TcA1 and TcA2 (TcB1 and TcB2) of the same type cut at the splicing position SP1 are respectively provided on a jig 20 that can be moved up and down as shown in FIG. The feed holes HcA (HcB) of the carrier tapes TcA1 and TcA2 are engaged with the positioning pins 21 and 22, respectively. In this state, the splicing positions SP1 of the carrier tapes TcA1 and TcA2 are connected (spliced) by a splicing tape (not shown). The positioning pins 21 and 22 are arranged, for example, at a pitch interval (2 / PhA) that is twice the pitch PhA of the feed holes HcA.

For this reason, even if the splicing positions (splicing surfaces) SP1 of the two carrier tapes TcA1 and TcA2 are not particularly accurate, the pitch of the feed holes Hc between the carrier tapes TcA1 and TcA2 can be accurately ensured.

Tar detection device 74a, is constituted by 74b or the like.

The cutters 68a and 68b of the first and second cutting devices 55a and 55b cut the splicing positions SP1 of the first and second carrier tapes TcA1 and TcA2 positioned at the first and second tape cutting positions Lc1 and Lc2. In order to do so, it is mounted so as to be movable in the vertical direction.

The cams 69a and 69b of the first and second cutting devices 55a and 55b are rotated by the first and second motors 70a and 70b to move the cutters 68a and 68b in the vertical direction.

The pressing members 72a and 72b of the first and second cutting devices 55a and 55b are arranged at the splicing positions SP1 of the first and second carrier tapes TcA1 and TcA2 positioned at the first and second tape cutting positions Lc1 and Lc2.

The first and second movable members 77a and 77b include first and second movable conveyance paths 79a and 79b forming part of the first and second tape conveyance paths 60a and 60b, and the tape conveyance paths 60a and 60b.

The first and second movable members 77a and 77b are normally held at angular positions where the openings 80a and 80b are aligned with the first and second tape transport paths 60a and 60b (the state shown by the two-dot chain line in FIG. 4). After the unnecessary portions are taken in, the angular positions at which the movable transport paths 79a and 79b are aligned with the first and second tape transport paths 60a and 60b by the driving devices 76a and 76b (state shown by solid lines in FIG. 4). It is rotated until.

The first and second carrier tapes TcA1, TcA2 are cut at the splicing position SP1 by the first and second cutting devices 55a, 55b, and are transported by predetermined amounts S2a, S2b from the tape cutting positions Lc1, Lc2, respectively. Each of the splicing positions SP1 is abutted against each other at the tape connection position LS.

When the two carrier tapes TcA1 and TcA2 are respectively conveyed to the tape connection position LS, the jig 20 is raised, and the positioning pins 21 and 22 engage with the feed holes HcA of the two carrier tapes TcA1 and TcA2, respectively. In this state, the two carrier tapes TcA1 and TcA2 are spliced by a splicing tape (not shown). Thereby, even if the splicing positions (cut surfaces) SP1 of the two carrier tapes TcA1 and TcA2 are not particularly accurate, the accuracy of the center position of the feed hole HcA between the carrier tapes TcA1 and TcA2 can be ensured.

Next, the operation of cutting the carrier tape at the vertical tangent of the feed hole by the splicing device 100 having the above configuration will be described. In the following, an example in which two carrier tapes TcA1 and TcA2 are spliced will be described.

When the power supply of the splicing device 100 is turned on, the control device 30 activates the first and second stepping motors 62a and 62b and starts rotating the first and second sprockets 61a and 61b. Then, the stepping motors 62a and 62b are positioned at the origin positions based on the detection signals of the first and second sprocket tooth detection devices 63a and 63b.

In this state, the first and second carrier tapes TcA1 and TcA2 are inserted from the first and second tape insertion openings 84a and 84b on both sides, respectively. Insertion of the first and second carrier tapes TcA1 and TcA2 is detected by the first and second tape detectors 64a and 64b, and the first and second stepping motors 62a and 62b are activated based on these detection signals. . Accordingly, the first and second sprockets 61a and 61b are rotated, and the first and second carrier tapes TcA1 and TcA2 having the feed holes HcA engaged with the teeth 67a and 67b of the sprockets 61a and 61b are the first and second carrier tapes TcA1 and TcA2, respectively. And it is conveyed on the 1st and 2nd tape conveyance paths 60a and 60b toward 2nd feed hole detection position Ld1 and Ld2.

When the first and second carrier tapes TcA1, TcA2 are conveyed to the first and second feed hole detection positions Ld1, Ld2, the first and second feed holes detecting devices 53a, 53b cause the first and second carrier tapes The center positions of the feed holes HcA of the tapes TcA1 and TcA2 are detected.

When the center position of the feed hole HcA of the first carrier tape TcA1 is detected by the first feed hole detection device 53a, the distance “S1a + d1” is moved from the position Ld1 where the center position of the feed hole HcA is detected to the first carrier tape TcA1. The first stepping motor 62a is rotationally controlled by the control device 30 so as to convey only "/ 2".

That is, since the distance between the first feed hole detection position Ld1 and the first tape cutting position Lc1 is “S1a”, the first carrier tape TcA1 is moved from the position Ld1 where the center position of the feed hole HcA is detected to the distance “ When only “S1a” is conveyed, the center position of the feed hole HcA is positioned at the first tape cutting position Lc1. Therefore, by further transporting the first carrier tape TcA1 by an extra half of the diameter d1 of the feed hole HcA, as shown in FIG. 5, the vertical tangent position SP1 of the feed hole HcA of the first carrier tape TcA1 is set. It can be positioned at the first tape cutting position Lc1.

Similarly, the second carrier tape TcA2 is conveyed by the distance “S1b−d1 / 2” from the position Ld2 where the center position of the feed hole HcA of the second carrier tape TcA2 is detected by the second feed hole detecting device 53b. In addition, the rotation of the second stepping motor 62b is controlled by the control device 30.

That is, since the distance between the second feed hole detection position Ld2 and the second tape cutting position Lc2 is “S1b”, the second carrier tape TcA2 is moved to the distance “ When transported from S1b to a position reduced by ½ of the diameter d1 of the feed hole HcA, as shown in FIG. 5, the vertical tangent position SP1 of the feed hole HcA of the second carrier tape TcA2 is changed to the second tape cutting position Lc2. Can be positioned.

Next, the first and second cutting devices 55a and 55b cut the vertical tangent position (splicing position) SP1 of the first and second carrier tapes TcA1 and TcA2, respectively. The cut unnecessary portions Tf1, Tf2 of the first and second carrier tapes TcA1, TcA2 are guided and discarded by the ducts 82a, 82 of the first and second intake members 75a, 75b.

That is, the cutters 68a and 68b of the first and second cutting devices 55a and 55b are lowered together with the pressing members 72a and 72b, respectively, and are moved to the first and second tape cutting positions Lc1 and Lc2 by the pressing members 72a and 72b. The vicinity of each splicing position SP1 of the positioned first and second carrier tapes TcA1, TcA2 is pressed and fixed. In this state, the cutters 68a and 68b are lowered to cut the first and second carrier tapes TcA1 and TcA2, respectively.

Next, the movable members 77a and 77b of the first and second intake members 75a and 75b are rotated, and in this state, the first and second carrier tapes TcA1 are used by the first and second tape feeders 51a and 51b. , TcA2 are conveyed toward the tape connection position LS by a certain distance S2a, S2b, respectively, and the splicing positions SP1 of the first and second carrier tapes TcA1, TcA2 cut are positioned at the tape connection position LS.

Thereafter, the jig 20 is raised, and the positioning pins 21 and 22 are engaged with the feed holes Hc of the two carrier tapes TcA1 and TcA2, respectively. Thereby, as shown to FIG. 2 (A), each splicing position SP1 of 1st and 2nd carrier tape TcA1, TcA2 is faced | matched. In this state, the two carrier tapes TcA1 and TcA2 are spliced by a splicing tape (not shown).

According to the embodiment described above, the vertical tangent position of the feed hole Hc may be set as the splicing position SP1 regardless of the two types of carrier tapes TcA and TcB having different cavities CtA and CtB. Therefore, the carrier tape TcA , There is no need to set the splicing position SP1 separately according to the type of TcB.

Therefore, in the case of manual splicing, the splicing position SP1 can be easily set, and workability can be improved. In addition, even in the case of automatic splicing, a mechanism for discriminating the types of carrier tapes TcA and TcB and the pitches of cavities CtA and CtB can be eliminated, so that the configuration of the splicing device 100 can be simplified and the manufacturing cost can be reduced. You can plan.

In the above-described embodiment, the distances between the feed hole detection positions Ld1, Ld2 and the tape cutting positions Lc1, Lc2 are set to be the same, and the transport amounts of the carrier tapes TcA1, TcA2 from the feed hole detection positions Ld1, Ld2 are set. An example in which the diameter is changed by the diameter d1 of the feed hole Hc has been described. However, if the distance between the feed hole detection positions Ld1, Ld2 and the tape cutting position Lc1, Lc2 is set in advance so as to have a difference by the diameter d1 of the feed hole Hc, the distance from the feed hole detection positions Ld1, Ld2 The transport amounts of the carrier tapes TcA1 and TcA2 can be made the same.

In the above-described embodiment, the feed hole detection positions Ld1, Ld2 are arranged between the sprockets 61a, 61b and the tape cutting positions Lc1, Lc2, and the carrier tape is placed at these feed hole detection positions Ld1, Ld2. The example in which the feed hole detecting devices 53a and 53b for detecting the center position of the feed hole HcA (HcB) of TcA (TcB) are provided has been described. However, since the center position of the feed hole HcA (HcB) can also be detected by positioning the sprockets 61a and 61b engaged with the feed hole HcA (HcB) at the origin position, the origin positions of the sprockets 61a and 61b are detected. Can also be used as the feed hole detection positions Ld1 and Ld2.

The above-described configurations of the tape feeding devices 51a and 51b, the cutting devices 55a and 55b, and the take-in members 75a and 75b are merely examples, and of course are not limited to those configurations. It is.
