Description

The present invention relates to a tape feeder for supplying components by pitch-feeding a carrier tape holding components, and a component mounting apparatus provided with this tape feeder.

2. Description of the Related Art Conventionally, as a component supply device used in a component mounting apparatus, a tape feeder for supplying components by pitch-feeding a carrier tape holding components has been widely used. The tape feeder pitch-feeds the carrier tape by engaging the pitch-feeding sprocket with the feed hole of the carrier tape and pitch-rotating the carrier tape to continuously feed the components one by one to the component supply port. Usually, the tape feeder is replenished with replenishment carrier tape before the tape feeder runs out of the carrier tape that is being supplied with components. In recent years, as a tape feeder capable of easily replenishing the carrier tape, a so-called autoload feeder has been proposed in which the carrier tape is automatically loaded into the tape feeder when the carrier tape is inserted through a tape insertion opening provided in the tape feeder. (For example, Patent Document 1 below). An automatic tape splicing device has also been proposed for automatically splicing the trailing end of a preceding carrier tape already loaded in a tape feeder and the leading end of a succeeding carrier tape (for replenishment). (For example, Patent Document 2 below).

In any of these devices, when the leading end of the carrier tape is inserted through the tape insertion port, the carrier tape is drawn into the interior by a drawing sprocket provided inside. The tape feeder has a pair of carrier tape support portions that support both ends in the width direction of the carrier tape inserted from the tape insertion port, and a concave groove formed between the pair of carrier tape support portions. When the carrier tape is of the embossed type, the concave grooves function as escape grooves for avoiding interference with the component holding portions protruding downward from the lower surface of the carrier tape.

4(a), (b) and FIGS. 5(a), (b), the guide portion 33 is located on the tape insertion opening 23K side end of the lower groove 42B (the end on the side where the carrier tape CT is inserted). part side). The guide portion 33 is the upper surface of the guide portion 33, and is the surface between both ends of the carrier tape CT inserted from the tape insertion opening 23K (the central portion in the width direction of the lower surface. The carrier tape CT is an embossed type. A guide surface 45 is provided for supporting the lower surface of the component holding portion S in some cases. The guide surface 45 extends over a predetermined length from the front side of the groove portion 42 (the tape insertion opening 23K side) toward the back side of the groove portion 42 in a state where the guide portion 33 is mounted in the lower groove 42B. It has a first support surface 45a located at a higher height than the carrier tape support 44. As shown in FIG. In the present embodiment, as shown in FIG. 4(a), the first support surface 45a is a horizontal surface positioned at a height higher than the carrier tape support portion 44, that is, positioned within the upper groove 42A. . The first support surface 45a is not limited to a horizontal surface, and may be an inclined surface or a combination of an inclined surface and a horizontal surface. The guide surface 45 is connected to the rear end of the first support surface 45a and gradually becomes lower than the carrier tape support portion 44 toward the rear side (that is, toward the insertion direction of the carrier tape CT). It has a lowered shape, that is, a sloped second support surface 45b.

As shown in FIGS. 4A and 4B, the tape pressing portion 32 is attached to the side wall portion 41. As shown in FIGS. The tape pressing portion 32 is positioned above the groove portion 42, and biases the inserted carrier tape CT toward the carrier tape support portion 44 by a biasing mechanism (not shown).

As described above, since the guide portion 33 has the first support surface 45a which is the same height as or higher than the pair of carrier tape support portions 44, the carrier tape CT is inserted through the tape insertion opening 23K. (Arrow A shown in FIG. 7), the carrier tape CT is first raised so that the surface between the ends thereof is the same as or higher than the pair of carrier tape support portions 44 by the first support surface 45a of the guide portion 33. (FIGS. 8(a) and 8(b), FIG. 8(b) being a cross-sectional view seen from the arrow V4-V4 in FIG. 8(a)).

Therefore, even if the carrier tape CT inserted from the tape insertion opening 23K is not in a horizontal posture, a part of the carrier tape CT (more specifically, one of both ends of the carrier tape CT) is inside the lower groove 42B. It can prevent you from falling. As described above, in the present embodiment, the guide portion 33 allows a portion of the carrier tape CT inserted into the upper groove 42A from the tape insertion opening 23K to enter the lower groove 42B from the end of the tape insertion opening 23K. It is a member that has the function of preventing

The carrier tape CT that has been inserted from the tape insertion opening 23K and advanced along the tape running path 23 (within the upper groove 42A) while being supported by the first supporting surface 45a at the surface between the two ends is , and is guided so as to be pressed from above by the upper guide surface 32a, which is the lower surface of the tape pressing portion 32, and both ends come into contact with the pair of carrier tape support portions 44 from above. , are supported (FIGS. 9(a) and 9(b); FIG. 9(b) is a cross-sectional view seen from the arrow V5-V5 in FIG. 9(a)). In this way, the carrier tape CT, which has advanced to the far side while its lower surface is in contact with the carrier tape support portion 44, passes through the guide portion 33, and then the feed hole H is engaged with the engagement pin 25p of the pull-in sprocket 25. (Fig. 10).

As described above, the tape feeder 13 in the present embodiment is provided at the end of the lower groove 42B on the side of the tape insertion opening 23K, and has the first support surface 45a higher than the pair of carrier tape support portions 44. , a guide portion 33 for supporting the surface between both ends of the carrier tape CT (central portion in the width direction of the lower surface).

For this reason, the surface between both ends of the carrier tape CT inserted from the tape insertion opening 23K (central portion in the width direction of the lower surface) is supported by the first support surface 45a of the guide portion 33 and the pair of carrier tape support portions. 44, and even if the carrier tape CT is tilted from the horizontal position, part of the carrier tape CT (one of both ends) enters the lower groove 42B. never. Therefore, the tape feeder 13 can be reliably loaded with the carrier tape CT.

Further, the tape feeder 13 in the present embodiment inserts the carrier tape CT into the carrier tape support portions 44 so that both ends of the carrier tape CT inserted from the tape insertion opening 23K come into contact with the pair of carrier tape support portions 44 from above. A tape pressing portion 32 is provided to press the side, and the carrier tape CT after being inserted is reliably supported by the carrier tape supporting portion 44. - 特許庁As a result, the feed hole H of the carrier tape CT that has passed through the guide portion 33 is reliably engaged with the engagement pin 25p of the pull-in sprocket 25, and loading errors are less likely to occur.

Further, in the tape feeder 13 of this embodiment, the first support surface 45a of the guide portion 33 is connected to the second support surface 45b that gradually lowers in the insertion direction of the carrier tape CT. , the carrier tape CT inserted into the tape insertion opening 23K descends along the second support surface 45b and is guided to come into contact with the carrier tape support portion 44. As shown in FIG. Therefore, the carrier tape CT can be guided toward the carrier tape support portion 44 in a natural posture along the second support surface 45b, and the engagement pin between the feed hole H of the carrier tape CT and the pull-in sprocket 25 can be adjusted. 25p can be reliably engaged.

In the above-described embodiment, the carrier tape CT used in the tape feeder 13 is of the embossed type. The same effect can be obtained with a carrier tape CT of a type in which the component holding portion S does not protrude downward from the bottom surface (that is, a type with a flat bottom surface) (Fig. 11(a) → Fig. 11(b)). )).

Also, the first support surface 45a of the guide portion 33 is higher than the carrier tape support portion 44 that supports both ends of the lower surface of the carrier tape CT. 44 may be the same height. That is, the guide portion 33 is provided at the end portion of the lower groove 42B (concave groove) on the side of the tape insertion opening 23K, and has a height equal to or higher than that of the pair of carrier tape support portions 44. It is sufficient that the first support surface 45a supports the surface between both ends of the carrier tape CT inserted from the tape insertion opening 23K. Also, the tape feeder 13 does not necessarily have to be of the auto-loading type, and the guide section 33 described above can also be applied to a normal type in which the carrier tape CT is manually loaded by an operator.

The guide portion 33 provided in the tape feeder 13 described above can be provided in a tape splicing device 50 described below. In the tape splicing device 50 shown in FIG. 12, the trailing end of the carrier tape CT currently being pitch-fed and the leading end of the carrier tape CT for replenishment are moved toward each other, and the ends are brought into contact with each other. After that, a splicing device attaches a connecting tape ST between these two carrier tapes CT for connection (splicing).

As shown in FIG. 12, the tape splicing device 50 has a base body 51 consisting of a bottom plate 51a and a back plate 51b. A first elevating portion 53a and a second elevating portion 53b are mounted, and a fork portion 55 driven in the front-rear direction by a second driving means 54 is attached. Above the first lifting portion 53a and the second lifting portion 53b, there is provided a connection tape supply portion 56 for supplying the connection tape ST in a state of being attached to the tape member. A moving table 57 is provided on the upper surface side of the bottom plate 51a of the base body 51, and the moving table 57 is provided with a carrier tape conveying section 58 and a pressing table 59. A moving table drive unit 60 for moving the moving table 57 in the front-rear direction is provided on the back plate 51b.

In FIG. 12, the carrier tape conveying section 58 includes left and right tape running paths 23 into which two carrier tapes CT to be connected are respectively inserted, a tape pressing section 32 and a guiding section 33 . These components have the same configuration as the tape running path 23, the tape holding portion 32, and the guide portion 33 provided in the tape feeder 13, and are denoted by the same reference numerals. In addition, the two inserted carrier tapes CT are respectively pulled in and their ends are butted against each other on the pressing table 59. Left and right sprockets (having the same configuration as the sprockets 25 provided in the tape feeder 13 described above and denoted by reference numerals are the same).

However, in this tape splicing device 50, as shown in FIGS. 13(a) and 13(b), one of the pair of side wall portions 41 of the base portion 31 is partially swingable upward by a hinge 47. The tape holding portion 32 is attached to the movable portion 41a. The tape pressing portion 32 is positioned above the groove portion 42 in a normal state, but by swinging the movable portion 41a around a hinge shaft 47J extending in the front-rear direction of the hinge 47 (FIG. 13A). ), arrow P shown in (b)) can be moved to the side of the base portion 31 (FIGS. 13(a) and 13(b)).

In FIG. 12, when the ends of the two carrier tapes CT are butted against each other on the pressing table 59 by the carrier tape conveying unit 58 (arrow B shown in FIG. 14(a)), the connecting tape supply unit 56 feeds the reel. The connection tape ST cut to a predetermined length from the tape member 56b fed out by the portion 56a is positioned above the pressing table 59 (FIG. 14(a)). At this time, the front region Ha of the connecting tape ST is positioned above the two carrier tapes CT whose ends are butted against each other, and the rear region Hb of the connecting tape ST protrudes to the side (rear) of the two carrier tapes CT. located (FIG. 14(a)).

When the connecting tape ST is positioned above the pressing table 59, the first driving means 52 lowers the first lifting section 53a and the second lifting section 53b. As a result, the first lifting section 53a presses the front region Ha of the connecting tape ST between the two carrier tapes CT (arrow C1 shown in FIG. 14(b)), and the second lifting section 53b moves between the two carrier tapes CT. The back side of the tape CT is lowered, and the rear area Hb of the connection tape ST is bent downward (arrow D1 shown in FIG. 14(b)). Then, the fork portion 55 is driven by the second driving means 54 to move forward (arrow E1 shown in FIG. 15(a)), and the connecting tape ST bent downward by the second elevating portion 53b moves backward. By pressing the area Hb forward, the rear area Hb is folded back to the lower surface side of the carrier tape CT.

After the rear region Hb of the connecting tape ST is folded back to the lower surface side of the carrier tape CT in this manner, the fork portion 55 is returned to its original position by the second driving means 54 (as shown in FIG. 15(b)). Arrow E2), the first driving means 52 lifts the first lifting section 53a and the second lifting section 53b (arrow C2 and arrow D2 shown in FIG. 15B). As a result, the two carrier tapes CT are connected by the connecting tape ST, and the connecting work of the carrier tapes CT is completed (FIG. 15(b)).

When the work of connecting the carrier tape CT is completed, the moving table driving section 60 moves the moving table 57 forward (arrow F shown in FIG. 16). As a result, the carrier tape conveying portion 58 as a whole is pushed forward beyond the first lifting portion 53a. After the entire carrier tape conveying portion 58 is pushed forward beyond the first lifting portion 53a, the operator swings the left and right movable portions 41a around the hinge shaft 47J (as shown by the arrows shown in FIG. 17(a)). P)), and the upper portions of the left and right groove portions 42 are opened (FIG. 17(a)). Thereby, the operator can take out the carrier tape CT spliced by the splicing tape ST from the tape splicing device 50 (FIG. 17(b)).

The tape splicing device 50 shown here has a guiding portion 33 having the same configuration as that of the tape feeder 13 described above. For this reason, the surface between both ends of the carrier tape CT inserted from the tape insertion opening 23K (central portion in the width direction of the lower surface) is supported by the first support surface 45a of the guide portion 33 and the pair of carrier tape support portions. 44, and even if the carrier tape CT is tilted from the horizontal position, part of the carrier tape CT (one of both ends) enters the lower groove 42B. never. Therefore, the carrier tape CT can be reliably loaded into the tape splicing device 50 .
