  Embodiments of a component supply apparatus and a component mounting apparatus using the same according to the present invention will be described below with reference to the drawings.

<Embodiment 1 of component supply apparatus>
FIG. 1 schematically shows an overall configuration of a first embodiment of a component supply apparatus according to the present invention, and shows a state in which a cover 40 that covers an electronic component exposure device 30, a guide 13, a conveyance path 42, and the like is removed. It is shown.

  A component supply apparatus 10 shown in FIG. 1 sequentially feeds and supplies a component supply tape 1 wound around a storage tape reel 9 to a component extraction position, and the electronic component supplied by the component supply tape 1 at the component extraction position is a component. It is a device for taking out by the suction mounting device 54 and mounting it on a substrate or the like.

  The component supply tape 1 is mainly composed of a carrier tape 2 and a cover tape 3 as shown in FIG. 2A. As shown in FIG. 2B, the carrier tape 2 includes a component storage portion 5 formed by recessing the surface of the carrier tape 2 so that the electronic component 6 does not protrude from the surface of the carrier tape 2, and a component such as a sprocket. Both a tape feed device 11 (see FIG. 1) for feeding the supply tape 1 and a feed hole 4 for fitting are formed side by side at a predetermined interval in the conveyance direction of the component supply tape 1. In addition, you may form the components accommodating part 5 which accommodates the electronic component 6 by shape | molding the cross section of the carrier tape 2 in substantially U shape (refer FIG. 11).

  The cover tape 3 is provided so as to cover the component storage portion 5 in order to prevent the electronic component 6 stored in the component storage portion 5 of the carrier tape 2 from popping out. As shown in FIG. 2A, the carrier tape 2 and the cover tape 3 have both sides in a direction orthogonal to the conveying direction of the component storage unit 5 (hereinafter referred to as the width direction) (arrow X direction) via the bonding unit 7. It is glued. The adhesive portion 7 is formed, for example, by locally welding the carrier tape 2 and the cover tape 3 and solidifying by cooling, and is generally provided along the transport direction so that the distance from the component storage portion 5 is equal on both sides. ing.

  As for the positional relationship between the feed hole 4 formed in the carrier tape 2 and the component storage portion 5, the width (arrow X direction) and the conveyance direction (arrow Y direction) of the component supply tape 1 are standard (JIS C 0806- 3) is stipulated, and each manufacturer of the component supply tape 1 manufactures the component supply tape 1 so as to satisfy the standard. The size of the component supply tape 1 in the width direction is set so as to satisfy the relationship of “the width W6 of the electronic component 6 <the width W5 of the component storage unit 5 <the distance W7 between the bonding portions 7”. This is because the component storage unit 5 needs to design the width W5 of the component storage unit 5 to be larger than the width W6 of the electronic component 6 in order to store the electronic component 6, and an adhesive margin is provided on both sides of the component storage unit 5. This is because the distance W7 between the bonding portions 7 needs to be designed to be larger than the width W5 of the component storage portion 5.

  As shown in FIG. 1, the component supply device 10 is provided with a guide 13 that prevents the component supply tape 1 from deviating from the conveyance path 42. The component supply tape 1 wound around the storage tape reel 9 is intermittently fed in the conveyance direction (arrow Y direction) by the tape feeder 11 while being supported by the conveyance path 42 and the guide 13. The guide 13 is installed so as to cover the surface of the conveyance path 42 with a rod-shaped member having a substantially U-shaped cross section.

  The component supply device 10 includes an electronic component exposure device 30 on a conveyance path 42 between the storage tape reel 9 and the downstream tape feeding device 11 and a part of the guide 13 cut out. The cover tape 3 of the component supply tape 1 conveyed in the conveyance direction is cut by the electronic component exposure device 30, and the electronic component 6 stored in the component storage unit 5 is exposed from the component supply tape 1. The electronic component 6 exposed from the component supply tape 1 is held at the tip of the component suction mounting device 54 and taken out from the component storage portion 5 when the component suction mounting device 54 moves in the vertical direction (arrow Z direction). Is done. After the electronic component 6 is taken out, the component supply tape 1 is transported in the transport direction, then cut by the cutting device 12 and discarded.

  As shown in FIG. 3A, the electronic component exposing device 30 was cut by a substantially rectangular main body 31 in a plan view, a cutter (cover tape cutting portion) 32 that cuts the cover tape 3 between the bonding portions 7, and the cutter 32. It has a Russell portion 33 for opening the cover tape 3, a positioning guide 35 for positioning the component supply tape 1 conveyed to the cutter 32, and an attachment portion 36 for attaching the main body 31 and the like to the cover 40. Is formed.

  The cutter 32 is provided to protrude from the lower surface of the main body 31 at a location where a part of the main body 31 is cut out in a substantially rectangular shape. The Russell portion 33 is connected to the downstream side of the cutter 32 and has a shape in which the cover tape 3 cut by the cutter 32 is opened and opened on both sides. On the downstream side of the Russell portion 33, a component take-out hole 34 that penetrates the Russell portion 33 and the main body 31 in the vertical direction is formed in order to take out the electronic component 6 stored in the component storage portion 5. In addition, the cutter 32 and the Russell portion 33 have a symmetrical shape with respect to a plane passing through the center in the width direction of the Russell portion 33 in a plan view, for example. The positioning guide 35 is provided on the upstream side of the cutter 32 and restrains the cover tape 3 so that the cover tape 3 of the component supply tape 1 conveyed to the cutter 32 does not move vertically upward with respect to the upper surface of the cover tape 3. . Note that notches are formed in portions corresponding to the positioning guide 35 and the cutter 32 of the main body 31 so that the cutting of the cover tape 3 by the cutter 32 is not hindered.

  More specifically, as shown in FIG. 3B, the cutter 32 and the Russell portion 33 of the electronic component exposing device 30 are formed such that the lower surface slightly protrudes vertically downward from the lower surfaces of the main body 31 and the positioning guide 35. The cover tape 3 covering the electronic component 6 can be smoothly cut by 32. Further, each of the attachment portions 36 provided on both sides in the transport direction of the main body 31 has a step portion 29 extending in the width direction so that the upper surface thereof is vertically lower than the upper surface of the main body 31, and the electronic components are exposed. The movement of the device 30 in the width direction is guided. Each of the attachment portions 36 is formed with two screw holes 39 arranged in the width direction.

  As shown in FIG. 4A, the electronic component exposing device 30 is attached to the cover 40 that covers the electronic component exposing device 30, the guide 13, and the conveyance path 42 via the attachment portion 36.

  Specifically, a substantially rectangular opening 46 is formed on the upper surface of the cover 40 in a plan view, and the upstream side and the downstream side of the opening 46 are respectively above the screw holes 39 of the electronic component exposing device 30. Two elongated holes 45 extending in the width direction are formed in the corresponding portions. The width direction dimension of the opening 46 of the cover 40 is larger than the width direction dimension of the main body 31 of the electronic component exposing device 30. Thereby, a stepped screw 41 having a head larger than the width of the long hole 45 is inserted through the long hole 45 of the cover 40, and the screw 41 is formed in the mounting portion 36 of the electronic component exposing device 30. When the electronic component exposure device 30 is fastened to the screw hole 39, the electronic component exposure device 30 is slidably attached to the cover 40 so as to have a gap G1 on both sides in the width direction. A gap G1 is movably disposed on both sides. As described above, the upstream end portion and the downstream end portion of the opening 46 of the cover 40 are disposed in contact with the stepped portion 29 of the mounting portion 36 so as to guide the movement of the electronic component exposing device 30 in the width direction. It has become.

  Further, as shown in FIG. 4B, the cover 40 is integrally provided with a spring base 43 vertically below the electronic component exposing device 30 and the conveyance path 42. A compressed spring 44 is disposed between the conveyance path 42 and the spring base 43, and the cover 40 is urged toward the conveyance path 42 by the urging force of the spring 44, so that the electrons attached to the cover 40. The component exposure device 30 is pressed by the conveyance path 42 fixed in the vertical direction.

  As shown in FIG. 4C, the conveyance path 42 has a concave shape with a stepped cross section, and the upper stage side is a portion on which the component supply tape 1 is placed. On the other hand, for example, when the component storage portion 5 is formed by forming the cross section of the carrier tape 2 into a substantially U shape, the lower side is a portion where the component storage portion 5 is stored (see FIG. 11). .

  Next, the operation of exposing the electronic component 6 from the component supply tape 1 by the electronic component exposing device 30 will be described with reference to FIGS. 5A to 5E.

  When the end of the component supply tape 1 conveyed along the conveyance path 42 reaches the electronic component exposing device 30 and the positioning guide 35 contacts the cover tape 3, the component supply tape 1 is separated by the positioning guide 35 and the conveyance path 42. Is sandwiched vertically. Here, the positioning guide 35 positions the component supply tape 1 so that the tip of the cutter 32 protruding vertically downward from the positioning guide 35 is positioned between the cover tape 3 and the carrier tape 2 of the component supply tape 1. To do.

  When the component supply tape 1 is further conveyed in the conveyance direction and the end of the component supply tape 1 reaches the tip of the cutter 32, the cutter 32 reacts with the reaction force of the conveyance force of the tape feeder 11 with respect to the component supply tape 1. Disconnect. As shown in FIGS. 5A to 5C, the Russell portion 33 provided to be connected to the downstream side of the cutter 32 is formed on the cover tape 3 after being cut by the reaction force of the conveying force of the tape feeder 11 with respect to the component supply tape 1. Push the end to both sides in the width direction. Note that when the cutter 32 cuts the cover tape 3, the lower surfaces of the cutter 32 and the Russell portion 33 are positioned so as to come into contact with the upper surface of the carrier tape 2.

  As shown in FIG. 5D, the component supply tape 1 is further transported in the transport direction in a state where the end of the cover tape 3 after being cut by the Russell portion 33 is expanded in the width direction, and the component formed on the carrier tape 2 When the storage unit 5 reaches below the component extraction hole 34, the electronic component 6 in the component storage unit 5 is exposed through the component extraction hole 34 as shown in FIG. 5A. The electronic component 6 exposed through the component take-out hole 34 is held at the tip of the component suction mounting device 54 using, for example, a vacuum pressure or a chuck mechanism, and is taken out from the component storage unit 5 (see FIG. 1).

  The width of the Russell portion 33 and the component take-out hole 34 of the electronic component exposure device 30 described above (the dimension in the direction orthogonal to the conveying direction) is “the width of the component storage portion 5 <the width of the component take-out hole 34 <the Russell portion. It is formed so as to satisfy the relationship of the width of 33 <the distance between the bonding portions 7 ”. This is because it is necessary to design the width of the component extraction hole 34 to be larger than the width of the component storage unit 5 in order to reliably extract the electronic component 6 stored in the component storage unit 5 through the component extraction hole 34. It is. Further, the width of the raschel portion 33 is larger than the width of the component take-out hole 34 in order to reliably expose the electronic component 6 from the component take-out hole 34 in a state where the cover tape 3 after being cut is pushed and spread by the raschel portion 33. This is because it is necessary to design. Further, the distance between the adhesive portions 7 is designed to be larger than the width of the Russell portion 33 in order to prevent the cover tape 3 after being cut from riding on the adhesive portion 7 by arranging the Russell portion 33 between the adhesive portions 7. It is necessary to do. However, in order to reliably expose the electronic component 6 from the component extraction hole 34, it is desirable that the width of the component extraction hole 34 and the incision amount of the cover tape 3 are as large as possible. Therefore, the width of the raschel portion 33 and the component take-out hole 34 of the electronic component exposure device 30 is “the width of the component storage portion 5 <the width of the component take-out hole 34 <the width of the raschel portion 33 <the distance between the adhesive portions 7”. While satisfying the relationship, it is designed so that “the width of the component take-out hole 34 ≈ the width of the Russell portion 33 ≈ the distance between the bonding portions 7”.

  By the way, the cover tape 3 has an elastic force, and when the end portion of the cover tape 3 after being cut by the raschel portion 33 is pushed and expanded to both sides in the width direction, the pushing back force acting on the raschel portion 33 from the cover tape 3 is raschel. The portion 33 becomes larger as it approaches the adhesive portion 7. Therefore, if there is a difference in the distance between the component storage part 5 and the adhesive part 7 on both sides of the component storage part 5 and a difference in the distance between the raschel part 33 and the adhesive part 7 on both sides of the cover tape 3, The force that the raschel portion 33 receives from the cut cover tape 3 is greater when the distance between the portion 33 and the bonding portion 7 is shorter than when the distance between the raschel portion 33 and the bonding portion 7 is longer.

  The electronic component exposing device 30 is attached so as to be movable in the width direction with respect to the cover 40, and when there is a difference in the distance between the raschel portion 33 and the adhesive portion 7 on both sides of the cover tape 3 after cutting, the electronic component exposing device 30 is cut. It swings in the width direction according to the force received by the Russell portion 33 from the covered cover tape 3. Then, as shown in FIG. 5E, the electronic component exposing device 30 automatically moves to a position where the raschel portion 33 is between the adhesive portions 7 and the distance between the raschel portion 33 and the adhesive portion 7 is substantially equal on both sides. . That is, the electronic component exposing device 30 automatically moves to a position where the distance between the Russell portion 33 and the bonding portion 7 becomes substantially equal while the cover tape 3 is cut by the cutter 32 by the reaction force of the conveying force of the component supply tape 1. The electronic component 6 housed in the component housing portion 5 through the component take-out hole 34 is reliably exposed. More specifically, the adhesive portion 7 of the component supply tape 1 is formed unevenly on both sides of the component storage portion 5, and the cutter 32 installed at the approximate center in the width direction of the raschel portion 33 is the component storage portion 5 first. The electronic component exposure device 30 moves according to the force received by the Russell portion 33 from the cut cover tape 3 (rightward direction in the figure) The cutting position of the cover tape 3 is moved (to the right in the figure), and the cut cover tape 3 is pushed out of the component storage unit 5 and stored in the component storage unit 5 through the component extraction hole 34. The electronic component 6 is reliably exposed.

  In the first embodiment described above, in order to smoothly cut the cover tape 3 covering the electronic component 6 accommodated in the component accommodating portion 5, the cutter 32 is installed at the approximate center in the width direction of the raschel portion 33, and the cover The embodiment has been described in which the cutting position of the tape 3 is moved to a substantially intermediate position between the bonding portions 7 and the cover tape 3 is cut at the approximate center between the bonding portions 7. On the other hand, as shown in FIG. 6, the cutter 32 may not be installed at the approximate center in the width direction of the Russell portion 33 due to arrangement restrictions or the like. Even in such a case, the electronic component exposing device 30 is attached to the cover 40 so as to be movable in the width direction (direction orthogonal to the conveying direction), and the raschel portion 33, the component take-out hole 34, and the carrier tape 2 By appropriately arranging the component storage part 5, the adhesive part 7 and the like, the raschel part 33 is moved to an appropriate position between the adhesive parts 7 according to the force received by the raschel part 33 from the cover tape 3 after cutting. For example, the electronic component 6 accommodated in the component accommodating portion 5 can be reliably exposed through the component take-out hole 34 by avoiding the riding of the raschel portion 33 on the adhesive portion 7 or the cut cover tape 3 after cutting. .

<Embodiment 2 of component supply apparatus>

The cutting of the cover tape 3A by the cutter 32A is not hindered. Here, since the cutter 32A is movable in the width direction with respect to the fixed portion 30bA, the notches of the positioning guide 35A and the main body 31A are relatively set so as to correspond to the movement of the cutter 32A in the width direction. Widely formed.
