Description

  The present invention relates to a method for correcting a tape cutting position in a splicing device that splices the splicing surfaces of two carrier tapes.

  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 fed 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.

JP 2010-87390 A

  In this type of splicing device, the center position of the carrier tape feed hole is positioned at the tape cutting position by rotating the tape feed sprocket engaged with the carrier tape feed hole by a predetermined amount. It is designed to cut. Then, the cut portions of the two carrier tapes cut at the center position of the feed hole are spliced together.

  By the way, the carrier tape provided by the component manufacturer is manufactured within a tolerance (for example, ± 0.1 mm) with respect to the standard value of the pitch of the hole (for example, 4 mm). When the carrier tape has a + tolerance pitch, the carrier tape is cut at a position outside the center position of the feed hole. On the contrary, when the pitch of the feed holes is a carrier tape having a minus tolerance, the carrier tape is cut at a position inside the center position of the feed holes. As a result, when two carrier tapes are spliced, the cut portions may overlap or separate.

  That is, the two carrier tapes Tc1 and Tc2 cut by the cutting device are spliced at the time of splicing, with the feed holes Hc engaged with the positioning pins 21 and 22 on the jig 23, as shown in FIG. Splicing with tape or the like. For this reason, when the carrier tapes Tc1 and Tc2 are cut at a position outside the center position of the feed hole Hc, the cut portions of the two carrier tapes Tc1 and Tc2 overlap each other and feed the carrier tapes Tc1 and Tc2. It is possible that a conveyance failure will occur.

  On the contrary, if the carrier tapes Tc1 and Tc2 are cut at a position inside the center position of the feed hole Hc, the cut portions of the two carrier tapes Tc1 and Tc2 are separated from each other. Trouble occurs.

  Moreover, depending on the processing accuracy and assembly accuracy of the parts, an error may occur in the distance from the origin of the tape feed sprocket to the tape cutting position, and the carrier tape may vary in positioning accuracy due to the feed error caused by the tape feeder. Currently, it is difficult to eliminate these errors.

Arranged between each. The first and second carrier tapes Tc1, Tc2 are spliced at the center position (SP1) of the feed hole Hc.

  FIG. 2 shows an example of a splicing device 20 for splicing the first and second carrier tapes Tc1, Tc2. The splicing device 20 includes a tape feeding device 51 that conveys the carrier tape Tc1 (Tc2) toward the tape connection position LS along the longitudinal direction. FIG. 2 shows the tape feeding device 51 that transports the first carrier tape Tc1, but the tape feeding device that transports the second carrier tape Tc2 is disposed in contrast to the tape connection position LS. Since these are the same, illustration and description are omitted.

  On the tape feeder 51, the tape cutting position Lc is disposed at a position separated from the origin position Lg of the sprocket 61 by a predetermined distance D1. At the tape cutting position Lc, a cutting device 55 for cutting the carrier tape Tc1 at the center position of the feed hole Hc and a take-in device 57 for taking in an unnecessary portion at the cut end are provided.

  The tape feeding device 51 includes a tape transport path 60 provided so as to extend in the horizontal direction from the tape insertion port 84 toward the tape connection position LS, and a tape feed sprocket disposed below the tape transport path 60. 61, a stepping motor 62 as a feed motor connected to the sprocket 61, a sprocket tooth detecting device 63 arranged in the vicinity of the sprocket 61, a tape detecting device 64 arranged above the tape conveying path 60, and the like. Has been. The tape feeder 51 transports the carrier tape Tc1 along the tape transport path 60 so as to be positioned at the tape cutting position Lc and the tape connection position LS.

  The splicing device 20 is provided with a control device 30 (see FIG. 3) that controls the tape feeding device 51, the cutting device 55, the take-in device 57, and the like.

  The control device 30 is provided with an arithmetic processing device 31, a memory 32, a display device 33, a mode switch 34, and individual operation buttons 35. The mode switch 34 is switched when acquiring the correction value α of the tape cutting position Lc, and each individual operation button 35 is operated in the switching state, whereby each step feed is commanded to the stepping motor 62.

  In the sprocket 61, a plurality of teeth 67 having the same pitch as the pitch of the feed holes Hc are formed over the entire circumference. The sprocket 61 is engaged with the feed hole Hc of the carrier tape Tc1 inserted from the tape insertion port 84 into the uppermost tooth 67.

  The sprocket tooth detection device 63 detects that the sprocket 61 is positioned at the origin position Lg by reading a mark or the like attached to the side surface of the sprocket 61. The tape detector 64 detects that the carrier tape Tc1 has been inserted from the tape insertion port 84.

  The cutting device 55 includes a cutter 68 provided at the tape cutting position Lc, a cam 69 slidably contactable with the cutter 68, a motor 70 connected to the cam 69, and one end attached to the cutter 68, and the other end thereof. A cutter spring 71 attached to the fixed portion; a pressing member 72 provided adjacent to the cutter; a pressing spring 73 having one end attached to the cutter 68 and the other end attached to the pressing member 72; A cutter detection device 74 disposed in the vicinity of the cutter 68 is used.

  The cutter 68 of the cutting device 55 is mounted so as to be movable in the vertical direction in order to cut the carrier tape Tc1 positioned at the tape cutting position Lc. The cam 69 of the cutting device 55 is rotated by the motor 70 to move the cutter 68 in the vertical direction.

  The pressing member 72 of the cutting device 55 is provided so as to be movable in the vertical direction in order to press and fix the vicinity of the cutting surface (splicing surface) SP1 of the carrier tape Tc1 positioned at the tape cutting position Lc.

  The take-in device 57 includes a take-in member 75 including a movable member 77 and a fixed member 78, and a drive device 76 including a solenoid that drives the moveable member 77. The movable member 77 is rotatably supported by the fixed member 78. The movable member 77 is formed with a movable conveyance path 79 forming a part of the tape conveyance path 60 and an opening 80 for taking in an unnecessary portion of the carrier tape Tc1 conveyed on the tape conveyance path 60. Further, the movable member 77 is formed with a duct 82 for guiding the taken-in unnecessary portion to the disposal location.

  The movable member 77 is normally held at an angular position (a state indicated by a two-dot chain line in FIG. 2) where the opening 80 is aligned with the tape conveyance path 60, and after the unnecessary portion is taken in, the movable conveyance path 77 is 79 is rotated to an angular position (a state indicated by a solid line in FIG. 2) aligned with the tape transport path 60.

  The carrier tape Tc1 is positioned at the tape connection position LS by cutting the center position of the feed hole Hc by the cutting device 55 and transporting the carrier tape Tc1 by a predetermined distance D2 from the tape cutting position Lc.

  At the tape connection position LS of the splicing device 20, as shown in FIG. 4, two positionings each engageable with the feed holes Hc of the first and second carrier tapes Tc1 and Tc2 cut by the cutting device 55 are provided. The pins 21 and 22 are mounted on a jig 23 that can be moved up and down. The positioning pins 21 and 22 are arranged at a pitch interval (2P1) that is twice the pitch of the feed holes Hc, for example.

  When the first and second carrier tapes Tc1 and Tc2 are respectively conveyed to the tape connection position LS, the jig 23 is raised, and the positioning pins 21 and 22 are fed into the feed holes Hc of the first and second carrier tapes Tc1 and Tc2. Respectively engaged. As a result, the first and second carrier tapes Tc1, Tc2 are positioned, and the splicing surfaces SP1 of the two carrier tapes Tc1, Tc2 are brought into contact with each other.

  In this state, the first and second carrier tapes Tc1 and Tc2 are spliced by a splicing tape (not shown). Thereby, even if the splicing surfaces SP1 of the first and second carrier tapes Tc1, Tc2 are not particularly accurate, the center position of the feed hole Hc between the carrier tapes Tc1, Tc2 and the center position of the adjacent feed hole Hc Each pitch can be accurately secured at P1.

  When splicing (connecting) the first and second carrier tapes Tc1, Tc2, the power supply of the splicing device 20 is turned on. When the power is turned on, the control device 30 starts the stepping motor 62 and rotates the sprocket 61. Then, based on the detection signal of the sprocket tooth detector 63, the stepping motor 62 and the sprocket 61 are positioned at the origin position Lg.

  In this state, when the carrier tape Tc1 is inserted from the tape insertion port 84, the insertion of the carrier tape Tc1 is detected by the tape detection device 64, and the stepping motor 62 is rotationally controlled by the control device 30 based on the detection signal. The sprocket 61 is rotated by a predetermined amount by the stepping motor 62. As a result, the carrier tape Tc1 with the feed hole Hc engaged with the teeth 67 of the sprocket 61 is transported on the tape transport path 60 from the origin position Lg of the sprocket 61 toward the tape cutting position Lc by the distance D1.

  Next, the cutter 68 of the cutting device 55 is operated, and the carrier tape Tc1 is cut at the splicing surface SP1 at the center position of the feed hole Hc. The cut unnecessary portion of the carrier tape Tc1 is guided to the duct 82 of the take-in member 75 and discarded.

  Next, the movable member of the take-in member 75 is rotated, and in this state, the carrier tape Tc1 is moved by a predetermined distance D2 toward the tape connection position LS by the tape feeder 51.

  Thereafter, the jig 23 is raised, and the positioning pins 21 and 22 are engaged with the feed holes Hc of the first and second carrier tapes Tc1 and Tc2, respectively. Thereby, as shown in FIG. 4, each splicing surface SP1 of 1st and 2nd carrier tape Tc1, Tc2 is faced | matched. In this state, the first and second carrier tapes Tc1 and Tc2 are spliced by a splicing tape (not shown).

  By the way, the pitch accuracy of the feed hole Hc of the carrier tape Tc1 is within a tolerance (for example, ± 0.1 mm) determined by the standard. However, in the case of + tolerance, the carrier tape Tc1 is attached to the sprocket 61. Even if the predetermined distance D1 is conveyed from the origin position Lg, the center position of the feed hole Hc is positioned at a position before the tape cutting position Lc (see FIG. 5A).

  On the contrary, in the case of -tolerance, when the carrier tape Tc1 is transported a predetermined distance D1 from the origin position Lg, the center position of the feed hole Hc is positioned at a position beyond the tape cutting position Lc (FIG. 5B). reference).

  Accordingly, the carrier tape Tc1 cut by the cutter 68 of the cutting device 55 at the tape cutting position Lc has a dimension Δdx1 with respect to the center position of the feed hole Hc as shown in FIG. In the case of -tolerance, as shown in FIG. 5 (B), it is cut shorter by a dimension Δdx2 with respect to the center position of the feed hole Hc.

  In addition, the actual distance from the origin position Lg of the sprocket 61 to the tape cutting position Lc is designed by not only the pitch error of the feed hole Hc of the carrier tape Tc1 but also the processing and assembly accuracy of the components constituting the splicing device 20. In addition to the distance D1, the feeding error due to the tape feeding device 51 is combined, and an error occurs in the positioning accuracy of the carrier tape to the tape cutting position Lc.

  Therefore, when the two carrier tapes Tc1 and Tc2 cut by the cutting device 55 are engaged with the positioning pins 21 and 22 on the jig 23 at the tape connection position LS as shown in FIG. 4, the carrier tape Tc1 When Tc2 is cut longer, the joint (splicing surface SP1) of the two carrier tapes Tc1 and Tc2 overlaps.

  Therefore, in the present embodiment, the splicing can be performed without overlapping the joints of the two carrier tapes Tc1 and Tc2 and without generating a large gap between the two carrier tapes Tc1 and Tc2.

  FIG. 6 shows a tape cutting position correction method according to the present embodiment. In FIG. 6, reference numeral 90 denotes a belt-like master tape that is manufactured by imitating the carrier tape Tc1. The master tape 90 is made of metal or synthetic resin in which the engagement holes 91 corresponding to the feed holes Hc of the carrier tape Tc1 are formed with the same pitch as the feed holes Hc with high accuracy (without pitch error).

  The engagement hole 91 of the master tape 90 is engaged with the teeth 67 of the sprocket 61 for tape feeding, and is conveyed along the tape conveyance path 60 by the stepping motor 62. The master tape 90 is formed with a reference portion 93 having a reference surface that can be engaged with the blade of the cutter 68 and a locking portion 94 that can be locked to a dial gauge described later. The reference portion 93 is processed with high precision so as to be separated from the engagement hole 91 serving as a reference by a predetermined dimension.

  When the correction value of the tape cutting position Lc is acquired, the cutter 68 is held at the lower end by a cam 69 that is rotated by a motor 70 so that the reference portion 93 of the master tape 90 can come into contact. .

  The master tape 90 is fed from the tape cutting position Lc at which the reference portion 93 abuts against the cutter 68 to a position before the set amount d0 by the rotation control of the stepping motor 62 by the control device 30. In other words, the stepping motor 62 is given a command to transport the master tape 90 from the origin position Lg of the sprocket 61 by a distance “D1-d0”.

  At this time, if there is no processing or assembly error, no feeding error by the tape feeding device 51, etc., the interval between the reference portion 93 of the master tape 90 and the tape cutting position Lc is the set amount d0. The actual spacing will vary. The set amount d0 is set to, for example, about 0.5 mm (about 10 times the unit feed amount of a carrier tape described later).

  In an appropriate state, the dial gauge 95 is set on the fixed portion. Then, the measuring gauge 96 of the dial gauge 95 is locked to the locking portion 94 of the master tape 90, and the dial gauge 95 is adjusted so that the pointer swings due to the displacement of the master tape 90.

  Next, when the mode changeover switch 34 of the control device 30 is switched to the “measurement” side and each operation button 35 is operated, a feed command is issued to the stepping motor 62 and the stepping motor 62 is rotated by a unit angle. Thereby, the master tape 90 is moved by the unit feed amount dn (for example, 0.05 mm). Each time the operator operates each individual operation button 35, the operator checks the deflection of the dial gauge 95.

  While the pointer of the dial gauge 95 is swung, there is a gap between the reference portion 93 of the master tape 90 and the cutter 68. Therefore, the individual operation buttons 35 are further operated to operate the stepping motor. A feed command is given to 62 to move the master tape 90 by the unit feed amount dn. At this time, the number of operations of each individual operation button 35 is counted by a counter in the control device 30.

  In this manner, the individual operation buttons 35 are operated to feed the master tape 90 by the unit feed amount dn, and it is confirmed that the pointer of the dial gauge 95 does not swing despite the individual operation buttons 35 being operated. That is, when the reference portion 93 of the master tape 90 abuts against the blade of the cutter 68, the movement of the master tape 90 is prevented and the pointer of the dial gauge 95 does not shake, so the reference portion 93 is moved to the cutter 68 at the tape cutting position Lc. The contact can be detected.

  At this time, if there is no processing and assembling accuracy of parts or feeding error by the tape feeding device 51, that is, first, the reference portion 93 of the master tape 90 is exactly the set amount d0 before the tape cutting position Lc. If it is positioned, the master tape 90 is fed to a position where the pointer of the dial gauge 95 is not shaken by operating each individual operation button 35 NA times (NA = d0 / dn).

  However, the actual number NB of the individual operation buttons 35 until the pointer of the dial gauge 95 does not swing may be higher or lower than NA due to processing and assembly accuracy of parts or a feeding error by the tape feeder 51. This difference of “NA−NB” can be grasped as the processing error and the assembly accuracy of the parts, or the positioning error due to the feeding error by the tape feeding device 51, that is, the difference between the actual measurement value and the design value.

  In addition, since the actual carrier tape Tc1 (Tc2) has a variation in the pitch of the feed holes Hc, the individual operation buttons 35 are turned NC more than once after the pointer of the dial gauge 95 does not swing in consideration of the variation. A feed command is given to the stepping motor 62 by operating (for example, twice or three times). At this time, the reference portion 93 of the master tape 90 comes into contact with the cutter 68 and the sprocket 61 cannot rotate, so that the stepping motor 62 steps out.

Thereafter, the operator switches the mode changeover switch 34 of the control device 30 to the “registration” side. Thereby, in the arithmetic processing unit 31 of the control device 30, the following equation is calculated to obtain the correction value α.
α = (NA−NB + NC) × dn
This correction value α is registered in the memory 32 as a correction value of the tape cutting position Lc at the time of splicing.

  During splicing, when the carrier tape Tc1 (Tc2) is transported to the tape cutting position Lc, the correction value α is read from the memory 32 of the control device 30, and the carrier tape transport distance is set to the correction value α. It is transported in excess.

  Here, the correction value α is calculated in consideration of the pitch variation of the feed hole Hc (NC × dn) in addition to the actual error amount ((NA−NB) × dn). The splicing surface SP1 of the first and second carrier tapes Tc1 and Tc2 is not cut longer regardless of the processing and assembly accuracy, the feeding error due to the tape feeding device 51, and the variation in the feeding hole pitch of the carrier tape. . Accordingly, the two carrier tapes Tc1 and Tc2 can be spliced so that the splicing surfaces SP1 do not overlap at the tape connection position LS.

  FIG. 7 shows a flowchart for obtaining the correction value α described above. Hereinafter, the flowchart will be briefly described with reference to FIG.

  First, in step 102, the engagement hole 91 of the master tape 90 is engaged with the teeth 67 of the tape feed sprocket 61 positioned at the origin position Lg (see FIG. 2), and the master tape 90 is set. Further, the cutter 68 of the cutting device 55 is held at the descending end. Next, in step 104, the mode changeover switch 34 of the control device 30 is switched to the “measurement” side.

  In step 106, the rotation of the stepping motor 62 is controlled so that the master tape 90 conveys the distance “D1-d0” from the origin position Lg of the sprocket 61. As a result, the reference portion 93 of the master tape 90 is apparently positioned at a position in front of the tape cutting position Lc by the set amount d0. Next, in step 108, the dial gauge 95 is set on the fixed portion.

  Subsequently, in step 110, each individual operation button 35 of the control device 30 is operated. As a result, a feed command is issued to the stepping motor 62, and the stepping motor 62 is rotated by a unit angle. The master tape 90 is moved by the unit feed amount dn by the unit angle rotation of the stepping motor 62. As the master tape 90 moves, the pointer of the dial gauge 95 swings.

  In step 112, it is determined whether or not the dial gauge 95 has been shaken. If the pointer of the dial gauge 95 is swung (the determination result is NO), the process returns to the above-described step 110, the individual operation buttons 35 are operated, and the master tape 90 is further moved by the unit feed amount dn.

  In this manner, each individual operation button 35 is operated NB times, the reference portion 93 of the master tape 90 comes into contact with the cutter 68, and the dial gauge 95 does not sway (the determination result is YES). In step 114, each individual operation button 35 is further operated NC times, and an NC feed command is given to the stepping motor 62.

  Next, in step 116, the mode switch 34 is switched to the “registration” side. As a result, the correction value α (α = (NA−NB + NC) × dn) is calculated by the arithmetic processing unit 31 of the control device 30, and the correction value α is registered in the memory 32.

  As described above, according to the present embodiment, the correction value α is calculated in consideration of the variation in the pitch of the feed holes Hc in the processing and assembly accuracy of the parts and the feed error by the tape feeder 51. Regardless of the pitch error of the feed hole Hc of the carrier tape Tc1 (Tc2), the feed error by the tape feeder 51, etc., the splicing surface SP1 of the carrier tape Tc1 (Tc2) is not cut longer. As a result, the two carrier tapes Tc1 and Tc2 can be spliced so that the splicing surfaces SP1 do not overlap each other, and it is possible to suppress the occurrence of a transport failure in the feeder that transports the carrier tapes Tc1 and Tc2.

  The distance from the origin position Lg of the tape feed sprocket 61 to the tape cutting position Lc is measured by using a master or the like, and this is compared with the design value to obtain an error in processing and assembly. The position of the sprocket tooth detection device 63 that detects the origin position Lg of the sprocket 61 may be adjusted by the amount, and the origin position Lg of the sprocket 61 may be mechanically corrected.

  In the above-described embodiment, in order to control the master tape 90 to be fed by the unit feed amount dn, each operation button 35 is operated to give a feed command to the stepping motor 62. The configuration is not limited to such a configuration, and an operation jig may be appropriately connected to the control board of the control device 30 to give a feed command to the stepping motor 62.

  In the above embodiment, the dial gauge 95 detects that the reference portion 93 of the master tape 90 has reached the tape cutting position Lc from the set position, and measures the distance to the tape cutting position Lc. However, the present invention is not limited to such a configuration, and the distance from the setting position to the tape cutting position Lc by which the reference portion 93 of the master tape 90 reaches the tape cutting position Lc is set as appropriate except for the dial gauge 95. You may make it measure using a simple indicator.

  Furthermore, in the above-described embodiment, after the reference portion 93 of the master tape 90 contacts the cutter 68, a feed command is given to the (NC) stepping motor 62 a plurality of times to obtain the correction value α. . However, a fixed value can be added to the error in the distance until the reference portion 93 contacts the cutter 68 to obtain the correction value α.

  Thus, the present invention can take various forms without departing from the spirit of the present invention described in the claims.
