Component supply device

Abstract

The present invention provides a component supply device which suppresses the occurrence of defects caused by a state in which a component is attached to a cover tape when the cover tape is peeled off from a carrier tape. The tape feeder is provided with a tape cover (40), an air ejection unit (61), and a magnet member (90). The tape cover is provided with a slit portion (42) having an inducing edge (44) for inducing an extended portion (ES) of the cover tape (TT) extending from the tip of the carrier tape (CT) in a direction in which the extended portion (ES) is separated upward from the conveyance path (22), and an opposing edge (45) opposing the inducing edge (44). The air ejection part ejects air from the lower part of the tape cover, and blows up the extension part (ES) of the carrier tape (CT) to move the extension part (ES) from the slit part to the upper part of the tape cover. The magnet member is located at a position spanning from an upstream side to a downstream side of the slit portion in a region below the slit portion, and attracts a component (BH) in the carrier tape (CT) passing below the slit portion downward.

Description

Technical Field

[0001] The present invention relates to a component supply device for supplying components to a component mounting device. Background Art

[0002] Conventionally, component mounting devices for producing mounting substrates with components mounted on the substrate consisted of a component supply device that supplies components and a mounting head that picks up the components supplied by the component supply device and mounts them on the substrate. The component supply device, for example, employs a tape feeder that uses a carrier tape to supply components. The carrier tape has a structure in which components are stored in recesses arranged in a row, and then the recesses are covered with a cover tape. The tape feeder includes a transport mechanism that transports the carrier tape toward the component removal position, and a tape cover that covers the area near the component removal position of the transported carrier tape from above. The tape cover has an opening (component removal opening) for removing components at the component removal position, and the cover tape is peeled off from the carrier tape just before it reaches the component removal opening.

[0003] In the tape feeder described in Patent Document 1, as a mechanism for initially peeling the cover tape from the carrier tape (initial peeling), air is blown up a portion of the cover tape (the extension) extending from the front end of the carrier tape. This blown extension passes through a slit formed in the tape cover and moves upward toward the tape cover. After this initial peeling, the downstream edge of the slit enters the space between the carrier tape and the cover tape. Therefore, when the carrier tape is subsequently transported, the cover tape is peeled from the carrier tape by the transporting action.

[0007] Problems to be solved by the invention

[0008] Furthermore, components within the carrier tape's grooves typically remain in contact with the groove's bottom surface due to their own weight. However, if the components become charged due to static electricity, they may cling to the back of the cover tape. Furthermore, if the cover tape is peeled from the carrier tape in this state, the components attached to the cover tape pass through the slit along with the cover tape, leaving the groove empty. This can cause a pickup error where the mounting head cannot pick up the components, or damage the components due to collision with the edge of the slit as the cover tape passes through it.

[0009] Therefore, an object of the present invention is to provide a component supply device that can suppress the occurrence of a malfunction caused by components being stuck to the cover tape when the cover tape is peeled off from the carrier tape.

[0010] Solutions to Problems

[0011] The component supply device of the present invention transports a carrier tape containing components and peels off a cover tape from the carrier tape before the components reach a component removal position so that the components are located at the component removal position in an exposed state capable of being removed, wherein the component supply device comprises: a transport mechanism that transports the carrier tape along a transport path; a tape cover that is arranged to cover the carrier tape transported along the transport path from above and has a function of separating an extension portion, which is an extension portion of the cover tape extending from the front end of the carrier tape, from the transport path upward at a position upstream of the component removal position. an inducing edge for guiding in the direction of the belt cover and an opposing edge located on the upstream side of the inducing edge and opposite to the inducing edge; an air blowing portion for blowing out air from below the belt cover to blow up the extension portion of the carrier belt conveyed along the conveying path so as to move the extension portion from the slit portion between the inducing edge and the opposing edge toward above the belt cover; and a magnet member located in a region below the slit portion, spanning from the upstream side to the downstream side of the slit portion, and attracting downward the components in the carrier belt passing below the slit portion.

[0055] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a perspective view of a component mounting device including a tape feeder according to one embodiment of the present invention. Figure 1 The present invention illustrates a component placement device 1 equipped with a tape feeder, which is one embodiment of a component supply device according to the present invention. The component placement device 1 places components BH on a substrate KB and includes a substrate transport unit 12 on a base 11. A placement head 13 is provided above the base 11. The placement head 13 is moved horizontally by a head moving mechanism (not shown). The placement head 13 includes a plurality of nozzles 14 extending downward.

[0056] The substrate transport unit 12 transports the substrate KB horizontally and positions it at a predetermined work position. Hereinafter, the transport direction of the substrate KB by the substrate transport unit 12 is referred to as the X direction, and the horizontal direction perpendicular to the X direction is referred to as the Y direction. Furthermore, the vertical direction is referred to as the Z direction. Furthermore, the direction toward the center of the base 11 in the Y direction is referred to as "forward," and the direction toward the opposite side is referred to as "rearward."

[0057] exist Figure 1 In the embodiment, a trolley 15 is connected to the rear end of the base 11. The trolley 15 includes a feeder base 15a and a reel holder 15b. A plurality of tape feeders 16 are mounted on the feeder base 15a in an array along the X direction. Each tape feeder 16 is detachably mounted on the feeder base 15a.

[0058] exist Figure 1 In the embodiment, a plurality of reels RL corresponding to the plurality of tape feeders 16 attached to the feeder base 15a are held in a row in the X direction by the reel holder 15b. A carrier tape CT is wound around each reel RL.

[0059] Figure 2 (a) and Figure 2 (b) is a perspective view of the front end portion of the carrier tape conveyed by the tape feeder in one embodiment of the present invention. Figure 2 In (a) and (b), the carrier tape CT is provided with a plurality of component-receiving recesses PK arranged in a row. A plurality of feed holes KH are arranged in a row in the carrier tape CT, parallel to the row of recesses PK. Each recess PK accommodates a component BH, and the components BH in the recess PK are covered and sealed within the recess PK by a cover tape TT affixed to the top surface of the carrier tape CT.

[0060] exist Figure 2 In (a), the front end of the cover tape TT is processed to extend a certain length longer than the front end of the carrier tape CT. The portion of the cover tape TT extending from the front end of the carrier tape CT is hereinafter referred to as the "extension portion ES" of the cover tape TT.

[0061] Figure 3 : is a side view of a tape feeder in one embodiment of the present invention. Figure 3 In the embodiment, the tape feeder 16 comprises a main body 21 that is attached to and detached from the feeder base 15a. A conveying path 22 is formed within the main body 21 as a passage for conveying the carrier tape CT. The upper surface of the conveying path 22 serves as a conveying surface 22M that supports the lower surface of the carrier tape CT.

[0062] exist Figure 3In the embodiment, a tape insertion port 23 is formed at the rear end of the main body 21, into which the carrier tape CT pulled from the reel RL is inserted from the front end. A tape discharge port 24 is formed at the front end of the main body 21, from which the carrier tape CT traveling through the conveyance path 22 is discharged. A component removal position 16T, where the mounting head 13 removes components BH, is set between the positioning sprocket 32 and the discharge sprocket 33 on the upper surface of the main body 21.

[0063] exist Figure 3 In the embodiment, a conveying mechanism 30 is provided in the main body 21 for conveying the carrier tape CT inserted from the tape insertion port 23 along the conveying path 22. Figure 3 As shown, the conveying mechanism 30 includes three sprockets (introduction sprocket 31, positioning sprocket 32 and discharge sprocket 33) arranged from the rear to the front and a sprocket drive motor 34. The sprocket drive motor 34 is provided in the feeder control unit 35 ( Figure 3 ) is controlled to work, and the three sprockets are moved in the same direction ( Figure 3 clockwise direction in the figure) and rotate synchronously.

[0064] Figure 4 1 is a side view of a portion of a tape feeder in one embodiment of the present invention. Figure 4 In the conveyor belt 22, a plurality of feed pins PN are provided on the outer periphery of each of the three sprockets (the inlet sprocket 31, the positioning sprocket 32, and the discharge sprocket 33). When these three sprockets are rotated by the sprocket drive motor 34, the feed pins PN of each sprocket engage with the feed holes KH provided in the carrier tape CT from below, causing the carrier tape CT on the conveyor belt 22 to advance forward (downstream). At this time, the carrier tape CT is transferred in the order of the inlet sprocket 31, the positioning sprocket 32, and the discharge sprocket 33.

[0065] exist Figure 3 as well as Figure 4 In the embodiment, a tape cover 40 is provided on the upper portion of the main body 21. The tape cover 40 covers a portion of the area between the introduction sprocket 31 and the discharge sprocket 33 of the carrier tape CT conveyed along the conveyance path 22 from above. Thus, in this embodiment, the tape cover 40 is provided so as to cover the carrier tape CT conveyed along the conveyance path 22 from above.

[0066] Figure 5 1 is a perspective view of a tape cover provided in a tape feeder according to an embodiment of the present invention. Figure 5 In the embodiment, the tape cover 40 is formed of a single plate-shaped member, and its lower surface has a shape that is generally along the upper surface of the conveyor path 22. The rear portion of the tape cover 40 (the portion into which the carrier tape CT on the conveyor path 22 enters) is formed into an inclined portion 41 (see also FIG. 1 ) that is inclined relative to the conveyor path 22 so that the height from the conveyor path 22 (conveying surface 22M) increases toward the rear (upstream side). Figure 6 . Figure 6 yes Figure 5 (enlarged view of area AR1 in FIG). Figure 6 It is an enlarged perspective view of a part of the tape cover included in the tape feeder in one embodiment of the present invention.

[0067] exist Figure 5 as well as Figure 6 A slit 42 extending in the width direction (X direction) of the tape cover 40 is formed slightly downstream of the base of the inclined portion 41 of the tape cover 40 (thus, upstream of the component removal position 16T). Two air escape portions 43 are located at either end of the slit 42 in the width direction. The slit 42 is an open space formed between a downstream edge, a guide edge 44, and an upstream edge, an opposing edge 45, which opposes the guide edge 44. The guide edge 44 is formed by the edge of a protruding piece 44T located downstream of the slit 42 and protruding upstream. The guide edge 44 and the opposing edge 45 extend integrally in the X direction. The guide edge 44 guides the extension ES of the cover tape TT extending from the front end of the carrier tape CT upward (i.e., in a direction away from the conveying surface 22M).

[0068] Thus, in this embodiment, the tape cover 40 is configured to cover the carrier tape CT conveyed along the conveying path 22 from above, and has an extension portion ES that guides the extension portion of the cover tape TT extending from the front end of the carrier tape CT in a direction of separation upward from the conveying surface 22M at a position upstream of the component removal position 16T, and an opposing edge 45 located on the upstream side of the inducing edge 44 and opposite to the inducing edge 44.

[0069] Figure 7 A top view showing a portion of a tape cover of a tape feeder in one embodiment of the present invention together with a carrier tape. Figure 7 As shown, the width dimension L2 of the guide edge 44, which corresponds to the width dimension of the slit portion 42, is smaller than the width dimension U1 of the cover tape TT. However, the X-direction position of the guide edge 44 is set so as to include the groove PK of the carrier tape CT conveyed along the conveyance path 22 when viewed from above. Therefore, the component BH in the groove PK is guaranteed to pass below the guide edge 44 (below the slit portion 42).

[0070] Figure 7 The spacing L1 of the slit portion 42 shown, i.e., the distance separating the leading edge 44 and the opposing edge 45 in the Y direction, is set to be smaller than the thickness of the carrier tape CT and larger than the thickness of the cover tape TT. Furthermore, the width dimension L3 of the opposing edge 45 is set to be larger than the width dimension U1 of the cover tape TT and smaller than the width dimension U2 of the carrier tape CT.

[0071] exist Figure 6 as well as Figure 7 In the embodiment, the two air dissipation portions 43 provided in the belt cover 40 each consist of an opening connected to both ends of the slit portion 42 in the width direction (X direction), and their maximum dimension in the Y direction is larger than the interval L1 between the slit portions 42. In this embodiment, one of the two air dissipation portions 43 (the first air dissipation portion 43A) is provided inwardly in the width direction of the belt cover 40, while the other (the second air dissipation portion 43B) is provided facing the side edge of the belt cover 40.

[0072] exist Figure 5 A component removal opening 40K is provided near the downstream end of the tape cover 40. The component removal opening 40K is an opening for removing components BH from the carrier tape CT conveyed on the conveyance path 22 by the conveyance mechanism 30 using the nozzle 14 and is located above the aforementioned component removal position 16T.

[0073] exist Figure 5 In the embodiment, a sprocket avoidance hole 46 is provided upstream of the component removal opening 40K. The sprocket avoidance hole 46 is formed as a long hole extending in the longitudinal direction (Y direction) of the belt cover 40. The sprocket avoidance hole 46 has the function of preventing the feed pin PN of the positioning sprocket 32 from interfering with the belt cover 40.

[0074] As will be described later, the cover tape TT is removed from the carrier tape CT before it reaches the component removal opening 40K. Therefore, the carrier tape CT is transported by the transport mechanism 30, and the groove PK at the component removal position 16T is exposed upward from just below the component removal opening 40K. This allows the mounting head 13 (nozzle 14) to remove the component BH at the component removal position 16T through the component removal opening 40K.

[0075] exist Figure 3 as well as Figure 4 In the embodiment, an air ejection portion 61 for ejecting air upward is provided in the main body 21. The air ejection portion 61 is located below the slit portion 42.

[0076] Figure 8 This is a perspective view showing an air ejection portion included in the tape feeder according to one embodiment of the present invention together with a part of the tape cover. Figure 9 (a) is a side sectional view of a portion of the tape feeder in one embodiment of the present invention. Figure 9 (b) is a top view of a portion of the tape feeder in one embodiment of the present invention. Figure 8 as well as Figure 9In (a), the air ejection unit 61 is attached to a main body-side base 62 formed from a portion of the frame constituting the main body 21. The air ejection unit 61 has two air ejection ports 61H arranged side by side along the width direction (i.e., the X direction) of the belt cover 40. These two air ejection ports 61H extend through the block-shaped air ejection unit 61 in the thickness direction (the Z direction).

[0077] exist Figure 9 In (a), a communication space 63 opening toward the upper surface is formed in the main body base 62. An air tube 64 is connected to the communication space 63. The communication space 63 is connected to both outlets 61H. Therefore, when positive pressure is applied to the air tube 64, air (positive pressure air) is ejected from each of the two outlets 61H of the air ejection unit 61 through the communication space 63.

[0078] exist Figure 3 The air pipe 64 extends in the main body 21. The air pipe 64 is connected to the air outlet from the rear lower portion 21K of the main body 21 to the front ( Figure 3 It is connected to the air plug 66 that is protrudingly arranged on the right side of the paper).

[0079] When the tape feeder 16 is mounted on the feeder base 15a, the air plug 66 engages with an air jack (not shown) provided on the side of the feeder base 15a. The air jack is connected to a positive pressure source (not shown). Therefore, when the tape feeder 16 is mounted on the feeder base 15a, positive pressure can be supplied to the air pipe 64 via the air jack and the air plug. The feeder control unit 35 controls the air ejection control valve 65, thereby ejecting air from each of the two ejection ports 61H.

[0080] exist Figure 8 In the embodiment, the two air outlets 61H of the air outlet portion 61 are located opposite to the two air dispersing portions 43 (the first air dispersing portion 43A and the second air dispersing portion 43B) formed in the belt cover 40 in the direction (substantially in the vertical direction) along the flow of the air 67. Therefore, the air 67 ejected from the two air outlets 61H is as follows: Figure 8 As shown, the air passes through the two air escape portions 43 and flows upwards from the belt cover 40 .

[0081] The extension portion ES that has reached the slit portion 42 at the time when the air 67 is blown up is blown up by the air 67 and enters the upper portion of the belt cover 40 through the slit portion 42. As described above, Figure 7The interval L1 of the slit portion 42 shown is set to a size smaller than the thickness of the carrier tape CT and larger than the thickness of the cover tape TT. Therefore, the carrier tape CT conveyed along the conveying path 22 cannot pass through the slit portion 42, but the cover tape TT peeled from the carrier tape CT can pass through the slit portion 42.

[0082] In this manner, in this embodiment, the air blowing unit 61 blows air 67 from below the tape cover 40 to lift the extension portion ES of the carrier tape CT conveyed along the conveying path 22 and move the extension portion ES from the slit portion 42 between the guiding edge 44 and the opposing edge 45 toward the top of the tape cover 40.

[0083] Figure 10 1 is a side view of a portion of a tape feeder in one embodiment of the present invention. Figure 3 、 Figure 4 as well as Figure 10 ( Figure 10 yes Figure 4 In the enlarged view of the area AR2 in FIG, a tape introduction portion 74 composed of three rollers (a first roller 71 , a second roller 72 , and a third roller 73 ) is provided in the main body portion 21 .

[0084] Three rollers are located above the slit 42 of the belt cover 40. Each of the three rollers is comprised of a gear. The second roller 72 and the third roller 73 each have a smaller diameter than the first roller 71 and mesh with the first roller 71. The second roller 72 is located downstream of the first roller 71, while the third roller 73 is located above the first roller 71 (upstream of the second roller 72).

[0085] The driving force of the sprocket drive motor 34 is transmitted to the first roller 71 via a power transmission mechanism (not shown). When the first roller 71 is driven by the sprocket drive motor 34 and rotates, the second roller 72 and the third roller 73 meshing with the first roller 71 also rotate. At this time, the second roller 72 and the third roller 73 rotate in the opposite direction to the first roller 71. Specifically, the first roller 71 rotates Figure 10 The second roller 72 and the second roller 73 rotate in the counterclockwise direction (arrow R1 shown in the figure), and the ... Figure 10 The three rollers rotate in the clockwise direction (arrow R2 in the figure). These three rollers move in conjunction with the movement of the three sprockets (the introduction sprocket 31, the positioning sprocket 32, and the discharge sprocket 33).

[0086] exist Figure 10 In the embodiment, the guide portion 81 is provided on the downstream side of the first roller 71 . The guide surface 81M, which is the upstream side surface (the surface on the first roller 71 side) of the guide portion 81 , is formed in an arc shape along the outer peripheral surface of the first roller 71 .

[0087] exist Figure 4 as well as Figure 10In the embodiment of the present invention, a partitioning member 82 is provided above the conveyor path 22. The partitioning member 82 extends in the Y direction within the main body 21 and divides the space above the conveyor path 22 in the main body 21 into two parts. The upper area partitioned by the partitioning member 82 serves as a cover tape discharge space 83 into which the cover tape TT, after being peeled from the carrier tape CT, is fed.

[0088] exist Figure 8 as well as Figure 9 In (a) and (b), a magnet member 90 is provided below the slit portion 42 of the tape cover 40, extending from the upstream side to the downstream side of the slit portion 42. The magnet member 90 has the function of attracting the component BH in the carrier tape CT (in the groove PK) conveyed by the conveying mechanism 30 and passing below the slit portion 42 downward (toward the bottom surface of the groove PK) after the extension portion ES, which has been blown up by the air 67 ejected from the two ejection ports 61H, moves from the slit portion 42 toward the top of the tape cover 40.

[0089] In this embodiment, the magnet member 90 is attached to the upper surface of the air ejection portion 61 and can be freely changed in shape according to the number, arrangement, shape, etc. of the ejection ports 61H of the air 67 provided in the air ejection portion 61. Figure 8 as well as Figure 9 As shown in (b), the air ejection section 61 has two air ejection ports 61H arranged side by side in the X direction. Therefore, the magnet member 90 is positioned in the region between these two ejection ports 61H, spanning from the upstream side to the downstream side of the slit portion 42. Therefore, the magnet member 90 does not negatively affect the blowing of the extension portion ES by the air ejection section 61, and functions to attract the component BH downward as it moves from the upstream side to the downstream side of the slit portion 42.

[0090] In this embodiment, the magnet member 90 is attached to the upper surface of the air ejection section 61. However, a recessed portion having a depth corresponding to the thickness of the magnet member 90 may be formed in the surface of the air ejection section 61, and the magnet member 90 may be embedded in this recessed portion. With this configuration, the surface of the magnet member 90 and the surface of the air ejection section 61 are flush with each other, preventing the carrier tape CT passing therethrough from being obstructed by the height difference at the interface between the magnet member 90 and the air ejection section 61 (this also applies to the modified examples described below).

[0091] When the tape feeder 16 of the above-described structure is used to supply the component BH, the operator first inserts the leading end of the carrier tape CT with the extended portion ES of the cover tape TT formed thereon into the tape insertion port 23. The carrier tape CT is then pushed downstream until the leading end of the carrier tape CT contacts the feed pin PN of the introduction sprocket 31.

[0092] After pushing the carrier tape CT in until the front end of the carrier tape CT contacts the feed pin PN of the inlet sprocket 31, the operator operates the (not shown) start switch. Upon detecting that the start switch has been operated, the feeder control unit 35 activates the sprocket drive motor 34, rotating the three sprockets (the inlet sprocket 31, the positioning sprocket 32, and the discharge sprocket 33). As a result, the carrier tape CT within the conveyance path 22 is conveyed downstream by the three sprockets.

[0093] Figure 11 (a) and (b) are side views of a portion of the tape feeder in one embodiment of the present invention. After the carrier tape CT is conveyed downstream, and the extended portion ES of the cover tape TT enters the area below the inclined portion 41 of the tape cover 40, the feeder control unit 35 operates the air ejection control valve 65 to eject air 67 from the air ejection unit 61 (specifically, the two ejection ports 61H). Figure 11 (a)). As a result, the extended portion ES of the cover tape TT that has reached the slit portion 42 is blown upward by the air 67 ejected from the ejection port 61H, and moves toward the upper surface side of the tape cover 40 through the slit portion 42 ( Figure 11 (b) After the extension portion ES of the cover tape TT passes through the slit portion 42 toward the upper side of the tape cover 40 , the feeder control portion 35 stops the ejection of the air 67 from the air ejection portion 61 .

[0094] After the extension portion ES passes through the slit portion 42 toward the upper side of the tape cover 40, when the carrier tape CT is further conveyed, the front end portion of the carrier tape CT abuts against the lower surface of the inclined portion 41 of the tape cover 40 ( Figure 11 (b) ), while pushing up the entire tape cover 40, the tape extends between the lower surface of the tape cover 40 and the conveying path 22 (conveying surface 22M). As a result, the extended portion ES of the cover tape TT, which has passed through the slit portion 42 and moved upward from the tape cover 40, is clamped (captured) by the first roller 71 and the second roller 72, which rotate in opposite directions, and is pulled up.

[0095] As described above, the first roller 71 and the second roller 72 operate in conjunction with the three sprockets (the inlet sprocket 31, the positioning sprocket 32, and the discharge sprocket 33). Therefore, the cover tape TT is pulled up by the first roller 71 and the second roller 72 in conjunction with the advancement of the carrier tape CT.

[0096] Figure 12 (a) is a side view of a portion of a tape feeder in one embodiment of the present invention. Figure 12(b) is a top view of a portion of the tape feeder in one embodiment of the present invention. When the carrier tape CT moves along the conveying path 22 while the extended portion ES of the cover tape TT passes upward through the slit portion 42, the guide edge 44 forming the slit portion 42 enters the carrier tape CT and the cover tape TT. Therefore, as the carrier tape CT moves further, the cover tape TT is peeled off from the carrier tape CT in approximately synchronization with the movement of the carrier tape CT. Figure 12 (a), (b)). In this way, the cover tape TT is peeled off from the carrier tape CT with the slit portion 42 (more specifically, the guide edge 44) of the tape cover 40 as the peeling position.

[0097] Figure 13 This is a side view of a portion of the tape feeder in one embodiment of the present invention. In this embodiment, as described above, a magnet member 90 is provided below the slit portion 42 of the tape cover 40 in the conveying path 22. Therefore, even if the components BH in the carrier tape CT (in the groove PK) conveyed along the conveying path 22 are charged by static electricity or the like before reaching the slit portion 42 as the peeling position, and thus adhere to the back side of the cover tape TT from the inside of the groove PK, these components BH are attracted downward by the magnetic force JR of the magnet member 90 and return to the groove PK ( Figure 13 ).

[0098] Therefore, in this embodiment, the component BH attached to the cover tape TT does not squeeze through the slit portion 42 together with the cover tape TT peeled from the carrier tape CT, nor does the component BH collide with the edge of the slit portion 42 (particularly the guide edge 44) and be damaged.

[0099] The cover tape TT that has been peeled off from the carrier tape CT and passed through the slit portion 42 toward the upper surface side of the tape cover 40 as described above is caught and pulled up by the first roller 71 and the second roller 72, and then is guided by the guide surface 81M of the guide portion 81 and moves rearward (upstream) along an arc-shaped track along the outer peripheral surface of the first roller 71 ( Figure 12 (a)). The cover tape TT is then sandwiched between the first roller 71 and the third roller 73 rotating in opposite directions, conveyed rearward (upstream), and delivered to the cover tape discharge space 83 described above.

[0100] When the cover tape TT is peeled off from the carrier tape CT with the slit portion 42 serving as the peeling position as described above, the components within the recess PK are no longer covered by the cover tape TT at a position downstream of the peeling position, but are instead covered from above by the tape cover 40. Therefore, even after the components BH within the recess PK pass the peeling position, they remain housed within the recess PK until they reach the component removal position 16T (component removal opening 40K).

[0101] When the component BH stored in the carrier tape CT reaches the component removal position 16T, it is exposed upward through the component removal opening 40K of the tape cover 40. Therefore, the mounting head 13 can suck and remove the component BH located at the component removal position 16T by inserting the nozzle 14 through the component removal opening 40K (picking up the component BH from the recess PK).

[0102] As described above, the tape feeder 16 in this embodiment is configured to convey the carrier tape CT storing the components BH, peel the cover tape TT from the carrier tape CT before the components BH reach the component removal position 16T, and position the components BH at the component removal position 16T in an exposed state where they can be removed.

[0103] When the component mounting apparatus 1, which has the tape feeders 16 of this structure as the component supply device, performs a component mounting operation for mounting components BH on a substrate KB, the substrate KB supplied from outside the component mounting apparatus 1 is first brought in by the substrate transport unit 12 and positioned at a predetermined operating position. After the substrate KB is positioned at the operating position, each tape feeder 16 operates to supply the component BH to the component removal position 16T. The mounting head 13 then uses the nozzle 14 to suck and remove the component BH from the tape feeder 16. The mounting head 13 then moves the sucked component BH above the substrate KB and mounts the component BH at the target component mounting position determined on the substrate KB.

[0104] After the mounting head 13 has mounted all the components BH to be mounted on the substrate KB as described above, the substrate transport unit 12 unloads the substrate KB to the outside of the component mounting apparatus 1. This completes the component mounting operation for one substrate KB.

[0105] As described so far, the tape feeder 16 in this embodiment includes a magnet member 90 located in a region below the slit portion 42, extending from the upstream side to the downstream side of the slit portion 42. The magnet member 90 attracts downwardly the component BH within the carrier tape CT passing below the slit portion 42. Therefore, even if the component BH is attached to the back surface of the cover tape TT, the component BH is attracted downwardly by the magnetic force JR of the magnet member 90 and separated from the cover tape TT. Consequently, it is possible to suppress problems caused by peeling the cover tape TT from the carrier tape CT while maintaining the component BH attached to the cover tape TT. For example, it is possible to suppress the occurrence of suction errors, such as the component BH being squeezed through the slit portion 42 along with the cover tape TT, leaving the groove PK empty and causing the placement head 13 to fail to suction the component BH. Alternatively, it is possible to suppress the occurrence of damaged components BH, such as the component BH colliding with the edge of the slit portion 42 (particularly the guide edge 44), which is then placed on the substrate KB by the placement head 13.

[0106] Furthermore, the magnetic member 90 included in the tape feeder 16 in this embodiment only needs to be able to attract downward the components BH in the carrier tape CT passing below the slit portion 42 after the extension portion ES of the cover tape TT, which has been blown up by the air 67 ejected from the air ejection portion 61, moves from the slit portion 42 toward the top of the tape cover 40. Therefore, when the air ejection portion 61 has two ejection ports 61H for the air 67, as in this embodiment, the magnetic member 90 may be located in a region extending from the upstream side to the downstream side of the slit portion 42 between the two ejection ports 61H, and its shape is not limited thereto.

[0107] Figure 14 (a) is a plan view showing a first modified example of the magnet member included in the tape feeder in one embodiment of the present invention. Figure 14 (b) is a top view showing a second modified example of the magnet member provided in the tape feeder in one embodiment of the present invention. Figure 14 As shown in FIG. 1 (a) of the first modified example, the magnet member 90A has a trapezoidal shape in which the width (X direction) increases from the upstream side to the downstream side. Alternatively, the magnet member 90A may have a trapezoidal shape in which the width (X direction) decreases from the upstream side to the downstream side.

[0108] Or you can also Figure 14 As in the second modified example shown in FIG. 1 (b), the magnet member 90B has a triangular shape whose width (X direction) increases from the upstream side to the downstream side. Alternatively, the magnet member 90B may have a triangular shape whose width (X direction) decreases from the upstream side to the downstream side.

[0109] Figure 15 (a) is a plan view showing a third modified example of the magnet member included in the tape feeder in the embodiment of the present invention. Figure 15 (b) is a top view showing a fourth modified example of the magnet member provided in the tape feeder in one embodiment of the present invention. Alternatively, Figure 15 Like the magnet member 90C of the third modified example shown in (a), its shape is such that it has an upstream wide portion 91a at the upstream end portion, the dimension of which increases in the width direction (X direction) toward the upstream side, and has a downstream wide portion 91b at the downstream end portion, the dimension of which increases in the width direction toward the downstream side.

[0110] As described above, when the air ejection portion 61 includes two air ejection ports 61H, the magnet member 90 (including 90A, 90B, and 90C) may be located in a region between the two air ejection ports 61H.

[0111] like Figure 15As shown in (b), when the air ejection portion 61 has only one air ejection port 61H, as in the magnet member 90D of the fourth modified example, the air passage 92 is located in the area below the slit portion 42, spanning from the upstream side to the downstream side of the slit portion 42 and having a shape that allows the air 67 ejected from the air ejection portion 61 to pass from the bottom to the top. This can achieve the effect of attracting the component BH downward without hindering the flow of the air 67. In this case, the shape of the magnet member 90D is also irrelevant. It should be noted that in this example, the air passage 92 is also located in a position opposite to the direction of flow of the air 67 ejected from the ejection port 61H.

[0112] In this manner, when the air ejection portion 61 includes only one air ejection port 61H, the magnet member 90D may have the air passage 92 through which the air ejected from the ejection port 61H passes from the bottom to the top.

[0113] It should be noted that the magnet member 90 (including variations 90A, 90B, 90C, and 90D) preferably extends to near the component removal position 16T. This allows the component BH to be stably held within the recess PK of the carrier tape CT even after the cover tape TT has been peeled from the carrier tape CT. Furthermore, if the magnet member 90 extends to a position directly below the component removal position 16T, the nozzle 14 can stably pick up the component BH within the recess PK.

[0114] As described above, the tape feeder 16, serving as the component supply device in this embodiment, includes the magnet members 90 (90A, 90B, 90C, 90D) located in a region below the slit portion 42, extending from the upstream side to the downstream side of the slit portion 42, and attracting downwardly the components BH within the carrier tape CT passing below the slit portion 42. Even if the components BH within the recess PK within the carrier tape CT adhere to the back surface of the cover tape TT before the recess PK reaches the peeling position (slit portion 42), the components BH can be attracted downwardly by the magnetic force JR of the magnet members 90 and separated from the cover tape TT. Therefore, the tape feeder 16 in this embodiment can suppress the occurrence of problems caused by components BH adhering to the cover tape TT when the cover tape TT is peeled from the carrier tape CT.

[0115] While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications are possible. For example, in the above-described embodiments, air escape portions 43 are formed at both ends of the slit portion 42 in the width direction (X direction). However, this is not essential. Instead, the slit portion 42 may be formed longer in the width direction to allow the air 67 ejected from the air ejection portion 61 to pass therethrough.
