Japanese Patent Laid-Open No. 2003-31989 Japanese Patent No. 2580716

  In general, as shown in FIG. 9, two feed holes 11 of each component supply tape 10 are fitted into two positioning pins 12 for positioning, but the feed holes 11 of each component supply tape 10 are In order to perform the operation of fitting into the positioning pin 12 smoothly, it is necessary to make the diameter of the positioning pin 12 smaller than the inner diameter of the feed hole 11 and to provide clearance (play) therebetween. Accordingly, if the clearance is formed with a large clearance in consideration of workability, the component supply tape 10 may be connected in an inclined state from the ideal tape position due to the clearance. The position of each component shifts from the ideal component position, and the component suction position by the suction nozzle of the component mounting machine shifts, resulting in a decrease in component mounting accuracy, or a component suction failure, which decreases productivity.

  On the other hand, in order to improve the positioning accuracy of the component supply tape 10, the clearance between the feed hole 11 and the positioning pin 12 can be reduced, or the interval between the two positioning pins 12 can be increased. However, if the clearance is reduced, there is a drawback that the workability of the operation of fitting the feed hole 11 of the component supply tape 10 into the positioning pin 12 is deteriorated, and if the interval between the two positioning pins 12 is increased, the tape There is a disadvantage that the splicing device is increased in size because it is necessary to lengthen the set base 13.

  The present invention has been made in consideration of these circumstances. Accordingly, the object of the present invention is to increase the positioning accuracy of the component supply tape without deteriorating the workability of the operation of fitting the feed hole of the component supply tape into the positioning pin. It is an object of the present invention to provide a splicing device for a component supply tape that can improve and avoid an increase in the size of the splicing device.

  In order to achieve the above object, the invention according to claim 1 is set in a state where the cut ends of two component supply tapes each having a plurality of feed holes (sprocket holes) formed at a predetermined pitch are abutted and positioned. In the splicing device for the component supply tape that connects the two, the cut ends of the two component supply tapes to be connected are cut at positions where the feed holes are divided by half or smaller, respectively. The positioning pin A into which the feed hole of one component supply tape fits and the feed hole of the other component supply tape fit into the tape set base that is set in a state where the cut ends of the two component supply tapes are in contact with each other The positioning pins B and the center pins C into which the divided feed holes (divided feed holes) at the cut ends of the two component supply tapes are arranged in a straight line and face upward It is provided.

  In this configuration, the split feed holes at the cut ends of the two component supply tapes are fitted into the center pin C so as to be sandwiched from both sides, thereby using the split feed holes at the cut ends of the two component supply tapes. Since positioning is possible, even if the positioning pins A and B are at the same position as the conventional position, the distance between the feed holes used for positioning the component supply tape (the distance between the positioning pins A and B and the center pin C) is conventionally increased. Can also be long. Thereby, even if the clearance of the positioning pins A and B is the same as the conventional one, the positioning accuracy of the component supply tape can be improved by the amount that the interval between the feed holes used for positioning is longer than the conventional one, Since the clearance considering the fitting workability of the positioning pins A and B can be secured, the workability of the work of fitting the feed holes of the component supply tape into the positioning pins A and B can be prevented. Further, since the positions of the positioning pins A and B may be the same as the conventional one, it is not necessary to lengthen the tape setting table, and the splicing device can be prevented from being enlarged.

  In the present invention, the diameter of the center pin C may be set to be the same as the diameter of the positioning pins A and B, but the diameter of the center pin C is larger than the diameter of the positioning pins A and B as in claim 2. It may be formed. Since the center pin C is fitted with split feed holes at the cut ends of the component supply tape from both sides, the center pin C is split from the side of the center pin C even if the clearance between the center pin C and the split feed hole is reduced. The feed holes can be easily fitted, and the workability of fitting the divided feed holes into the center pin C does not have to be reduced. In addition, by reducing the clearance of the center pin C, the positioning accuracy by the center pin C can be improved.

  In the present invention, one positioning pin A and one positioning pin may be provided, and each component supply tape may be positioned by one positioning pin A and B and the center pin C. As described above, at least two positioning pins A and B may be provided, and each component supply tape may be positioned by at least two positioning pins A and B and the center pin C. For example, similarly to the conventional splicing device, even when two positioning pins A and B are provided, the positioning pins A and B may be at the same position as the conventional splicing device, and it is necessary to lengthen the tape set base. Absent. Moreover, since it is only necessary to add one central pin C to the conventional splicing device, it is possible to reduce the cost increase for improving the positioning accuracy of the component supply tape, and two positioning states of the component supply tape. The positioning pins A and B can be held stably.

An embodiment embodying the best mode for carrying out the present invention will be described below with reference to FIGS.
The component supply tape 20 to be connected is accommodated one by one in each of the concave component accommodating portions 21 (see FIGS. 5 and 6) formed in a line at a constant pitch on the carrier tape, and is placed on the upper surface of the carrier tape. By attaching the top tape so as to be peeled off, the upper surface opening of each component housing portion 21 is sealed with the top tape. A large number of circular feed holes 22 (sprocket holes) are formed in a row at a predetermined pitch (for example, 4 mm pitch) on one side edge of the component supply tape 20 in a fixed positional relationship with each component receiving portion 21. .

  In this embodiment, the cut ends of the two component supply tapes 20 to be connected are cut at positions where the feed holes 22 are divided in half (center positions of the feed holes 22). A semicircular divided feed hole 22a is located at the cut end of 20. In this case, as shown in FIG. 5, in the case of the component supply tape 20 in which the position of each feed hole 22 and the position of each component storage portion 21 are shifted by a half pitch, respectively, at an intermediate position between the component storage portions 21. In the case of the component supply tape 20 that is cut and has the component accommodating portion 21 positioned on the center line of each feed hole 22, the component is positioned on the center line (cut line) of the divided feed hole 22 a. The part 21 is also cut.

  Next, the configuration of the splicing device for the component supply tape 20 will be described with reference to FIGS. In the tape set base 24 set in a state where the cut ends of the two component supply tapes 20 to be connected are abutted with each other, two feed holes 22 into which one component supply tape 20 (tape in use) fits are fitted. The positioning pin A, the two positioning pins B into which the two feeding holes 22 of the other component supply tape 20 (new tape) are fitted, and the divided feeding holes 22a at the cut ends of the two component feeding tapes 20 are fitted. Center pins C to be stuck are arranged in a straight line and provided upward. The pitch of the two positioning pins A and the pitch of the two positioning pins B are set to an integral multiple of the pitch of the feed holes 22 (for example, 3 pitches or 4 pitches). The positioning pins A and B and the center pin C may be fixed by any method. For example, screwing, press-fitting, or adhesive fixing into the pin hole of the tape set base 24 may be used. good.

  As shown in FIG. 7, the positioning pins A and B and the center pin C are formed in a circular cross section corresponding to the circular feed hole 22 and the semicircular divided feed hole 22a, respectively. , B are set so as to ensure an appropriate clearance in consideration of the workability of fitting the feed hole 22. On the other hand, the diameter of the center pin C is set larger than the diameter of the positioning pins A and B. As a result, the clearance between the center pin C and the divided feed hole 22a is smaller than the clearance between the positioning pins A and B and the feed hole 22, and the clearance is infinitely close to zero.

  As shown in FIGS. 2 to 4, tape pressing plates 25 are provided on both the left and right sides of the tape setting table 24 so as to be capable of opening and closing in the vertical direction via shafts 26, and set on the tape setting table 24. The component supply tape 20 is pressed and held by the tape pressing plate 25 from above. Magnets 27 that attract and hold the tape pressing plate 25 are provided on both the left and right sides of the tape set base 24.

  An operation procedure for connecting two component supply tapes 20 (the in-use tape and the new tape) using the splicing device configured as described above will be described.

  First, when the two component supply tapes 20 are set on the tape set base 24, the semicircular divided feed holes 22a at the cut ends of the respective component supply tapes 20 are fitted into the center pin C from the side. Two parts are formed by abutting the inner peripheral edge of the divided feed hole 22a against the outer peripheral surface of the center pin C and fitting the two feed holes 22 of each part supply tape 20 into the positioning pins A and B from above. The supply tape 20 is set in a state of being positioned in a straight line on the tape setting table 24. At this time, if the divided feed holes 22a of the cut ends of the component supply tapes 20 are first fitted into the center pin C from the side, the position of the cut ends of the component supply tapes 20 can be accurately positioned. Therefore, the two feed holes 22 of each component supply tape 20 can be easily aligned with the positioning pins A and B, and the feed holes 22 can be easily fitted into the positioning pins A and B.

  As described above, after the two component supply tapes 20 are set in a straight line on the tape setting table 24, the tape pressing plate 25 is rotated downward to supply the components on the tape setting table 24. The tape 20 is pressed and held by the tape pressing plate 25 from above. In this state, the connection tape is affixed across the upper surfaces (top tapes) of the two component supply tapes 20 to connect the two component supply tapes 20. Thereafter, the tape pressing plate 25 is rotated upward, the component supply tape 20 is removed from the tape set base 24, and the connection tape is also attached to the lower surface of the connection portion of the component supply tape 20. Work) is completed.

  As another connection work method, when the component supply tape 20 is set on the tape set table 24, first, in order to prevent the components from being scattered from the component supply tape 20, first, the component supply tape 20 is placed on the tape set table 24. Set with the back side up, connect the back side of the component supply tape 20 with a connecting tape, and then remove the component supply tape 20 from the tape set base 24 and connect the front side of the component supply tape 20 You may make it connect with a tape. In addition, you may change suitably the attachment method of a connection tape.

  In the present embodiment described above, the divided feed holes 22a at the cut ends of the two component supply tapes 20 are fitted into the center pin C so as to be sandwiched from both sides thereof, thereby forming the cut ends of the two component supply tapes 20 at the cut ends. Since positioning can be performed using the divided feed holes 22a, even if the positioning pins A and B are at the same position as the conventional one, the distance between the feed holes 22 and 22a used for positioning the component supply tape 20 (positioning pins A and B The distance between B and the center pin C) can be made longer than before. As a result, even if the clearance between the positioning pins A and B and the feed hole 22 is the same as the conventional one, the distance between the feed holes 22 and 22a used for positioning is longer than the conventional one. Since the positioning accuracy can be improved and the clearance considering the workability of fitting the positioning pins A and B can be secured, the workability of the work of fitting the feed hole 22 of the component supply tape 20 into the positioning pins A and B. There is no need to make it worse. Furthermore, since the position of the positioning pins A and B may be the same as the conventional position, it is not necessary to lengthen the tape setting table 24, and an increase in the size of the splicing device can be avoided.

  In the present invention, the diameter of the center pin C may be set to be the same as the diameter of the positioning pins A and B, but the diameter of the center pin C is larger than the diameter of the positioning pins A and B as in this embodiment. If formed, the positioning accuracy of the component supply tape 20 can be further improved. The center pin C is fitted with semicircular divided feed holes 22a at the cut ends of the component supply tape 20 from both sides, so the clearance between the central pin C and the divided feed holes 22a is reduced to zero as much as possible. As for the close clearance, the divided feed hole 22a can be easily fitted from the side of the central pin C, and the workability of fitting the divided feed hole 22a into the central pin C can be prevented. In addition, by reducing the clearance of the center pin C, the positioning accuracy by the center pin C can be improved.

  Further, in the present invention, one positioning pin A and one B may be provided, and each component supply tape 20 may be positioned by one positioning pin A and B and the center pin C. If, as in the example, two positioning pins A and B are provided and each component supply tape 20 is positioned by the two positioning pins A and B and the center pin C, a conventional splicing device is provided. It is only necessary to add one central pin C to the above, and it is possible to reduce the cost increase for improving the positioning accuracy of the component supply tape 20 and to change the positioning state of the component supply tape 20 to the two positioning pins A, There is an advantage that B can be stably held. In this case, the positions of the positioning pins A and B may be the same as those of the conventional splicing device, and it is not necessary to lengthen the tape setting table 24. In the present invention, three or more positioning pins A and B may be provided.

  In this embodiment, the two component supply tapes 20 to be connected are each cut at a position where the feed hole 22 is divided in half (the center position of the feed hole 22), but as shown in FIG. The split feed holes 22a at the cut ends of the two component supply tapes 20 to be connected may be cut at positions where they are divided smaller than half of the feed holes 22, respectively. Even in this case, the divided feed hole 22a at the cut end of each component supply tape 20 is fitted into the center pin C from the side, and the inner peripheral edge of the divided feed hole 22a is brought into contact with the outer peripheral surface of the center pin C. Thereby, the position of the cutting end of the component supply tape 20 can be accurately positioned.

In the present invention, configurations other than the positioning pins A and B and the center pin C of the splicing device may be changed as appropriate.
Alternatively, the positioning pins A and B are deleted from the tape set base 24 and only the center pin C is provided, and a positioning groove or wall is formed on the upper surface of the tape set base 24 along the side edge of the component supply tape 20. The deviation in the pitch feed direction of the component supply tape 20 may be regulated by the central pin C, and the deviation in the rotational direction around the central pin C may be regulated by a positioning groove or wall.
