Figure 3As shown in (a) and (b) of FIG. 1 , a plurality of component storage recesses PK are arranged in a row on the carrier tape CT, and a plurality of feed holes KH are arranged in a row at positions parallel to the row of the component storage recesses PK.

[0043] exist Figure 3 In (a) and (b), each component storage groove PK stores one component BH, and a cover tape TT is attached to the upper surface of the carrier tape CT at a position covering the component storage groove PK. That is, the component BH is stored in the carrier tape CT in a state covered by the cover tape TT.

[0044] like Figure 3 (a), (b) or Figure 4 As shown in (a) and (b) of FIG. 1 , the cover tape TT has a leading portion SD protruding from the front end ST of the carrier tape CT. The leading portion SD may be Figure 3 As shown in (a) and (b) of FIG. 1 , the front end of the cover tape TT may be extended from the front end ST of the carrier tape CT. Figure 4 As shown in (a) and (b) of FIG. 1 , a part of the auxiliary tape HJ attached to the cover tape TT is protruded from the front end ST of the carrier tape CT.

[0045] In the case of a configuration in which the front end of the cover tape TT protrudes from the front end ST of the carrier tape CT, the leading portion SD is composed of a portion of the cover tape TT (the portion having a length L) extending from the front end ST of the carrier tape CT. Figure 3 (a)). In the case of using the auxiliary tape HJ, the leading portion SD is composed of a portion (the portion with a length L) of the auxiliary tape HJ extending from the front end ST of the carrier tape CT ( Figure 4 (b)).

[0046] exist Figure 5 (a), (b) and Figure 6 In the embodiment, the tape feeder 16 includes a main body 51 detachably mounted in the mounting slot 35 of the feeder base 21. Two positioning pins 52 protruding forward are provided at the front end of the main body 51.

[0047] exist Figure 5 (a), (b) and Figure 6 In the embodiment, a downward extending portion 53 extending downward is formed at the rear of the main body 51 of the tape feeder 16. A fixed portion 54, a connector 55, and an air connection portion 56 are provided on the front surface side of the downward extending portion 53 so as to protrude forward.

[0048] When the tape feeder 16 is mounted in the mounting slot 35, the engaged portion 51K ( Figure 6 ) is inserted between the feeder guides 41 ( Figure 2 (a) → Figure 2 (b)). Thus, the two positioning pins 52 are inserted into the upper and lower positioning holes 42, and the fixed portion 54 is fitted into the assembly hole 44. In addition, the connector 55 is connected to the electric socket 45, and the air connection portion 56 is connected to the air socket 46.

[0049] When the fixed portion 54 is fitted into the mounting hole 44, the fixed portion 54 is connected to a fixing portion (not shown) provided inside the table portion 31, and the tape feeder 16 is fixed to the table portion 31. When the connector 55 is connected to the electrical socket 45, the tape feeder 16 is electrically connected and connected for signal transmission with the table portion 31. When the air connection portion 56 is connected to the air socket 46, air can be supplied from the base 11 side to the tape feeder 16 side through the table portion 31.

[0050] exist Figure 6 and Figure 7 In the embodiment, the main body 51 of the tape feeder 16 has two side covers 51C extending along the YZ plane and facing each other in the X direction. A conveying path 61 for conveying the carrier tape CT is formed in a space sandwiched by the two side covers 51C. That is, the side covers 51C of the main body 51 are provided so as to sandwich the conveying path 61 for conveying the carrier tape CT.

[0051] exist Figure 6 In the embodiment, the conveying path 61 has a carrier tape introduction port 61A at the rear end of the main body 51 and a carrier tape discharge port 61B at the front end of the main body 51. The upper surface of the conveying path 61 is a conveying surface 61M (also see FIG. 61 ) that supports the carrier tape CT from below (the lower surface of the carrier tape CT). Figure 7 ).

[0052] exist Figure 6 In the embodiment, a carrier tape transporting unit 62 for transporting the carrier tape CT is provided at the front upper portion of the main body 51. The carrier tape transporting unit 62 is composed of three sprockets (introduction sprocket 62A, positioning sprocket 62B, and discharge sprocket 62C) arranged from the rear to the front and a sprocket drive motor 62D.

[0053] exist Figure 6 In the embodiment, a plurality of feed pins 62P are provided on the outer periphery of each of the introduction sprocket 62A, the positioning sprocket 62B and the discharge sprocket 62C. The three sprockets are rotated in the same direction by a sprocket drive motor 62D via a gear mechanism (not shown). The direction in which the three sprockets rotate is the direction in which the feed pin 62P located at the highest position of each sprocket moves forward. The operation of the sprocket drive motor 62D is controlled by a control unit 63 ( Figure 6 )control.

[0054] The carrier tape CT is pulled out from the reel RL, and its front end side (the side where the aforementioned leading portion SD is formed) is inserted into the conveying path 61 from the carrier tape introduction port 61A. The carrier tape CT inserted into the conveying path 61 is conveyed forward (downstream) by the three sprockets (the introduction sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C) rotationally driven by the sprocket drive motor 62D (i.e., by the carrier tape conveying portion 62). At this time, the carrier tape CT is transferred in the order of the introduction sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C.

[0055] The carrier tape CT conveyed to the downstream side by the carrier tape conveying section 62 is removed by the cover tape peeling section 64 ( Figure 6 ) The cover tape TT is peeled off. The carrier tape CT from which the cover tape TT has been peeled off directly moves to the downstream side, and at the time point when it passes through the component removal opening 16K, the components BH in the component storage recess PK are exposed due to the peeling off of the cover tape TT.

[0056] The cover tape TT peeled off by the cover tape peeling unit 64 is discharged toward a cover tape discharge path 65 ( Figure 6 The carrier tape CT after the component BH is picked up is discharged from the carrier tape discharge port 61B.

[0057] The component taking-out opening 16K is provided between the positioning sprocket 62B and the discharge sprocket 62C, and the exposed component BH is intermittently and sequentially located at the component taking-out position 16T set inside the component taking-out opening 16K. Thus, the mounting head 13 can adsorb and hold the component BH located at the component taking-out opening 16K (component taking-out position 16T) by the component holding nozzle 14, and take it out (pick it up) from the tape feeder 16.

[0058] As described above, in the present embodiment, carrier tape transport unit 62 transports carrier tape CT along transport path 61 with leading portion SD of cover tape TT advancing, so that component BH is located at component removal position 16T.

[0059] exist Figure 6 In the embodiment, the aforementioned air connection portion 56 provided in the lower extension portion 53 of the main body 51 is connected to the air ejection portion 67 provided in the upper front portion of the main body 51 through the air pipe 66 provided in the lower extension portion 53. The air ejection control valve 68 provided in the lower extension portion 53 is interposed in the air pipe 66.

[0060] When the tape feeder 16 is mounted on the feeder base 21, the air connection portion 56 is connected to the air socket 46 on the feeder base 21 side. In a state where the air connection portion 56 is connected to the air socket 46, the air supplied from the feeder base 21 side through the air pipe 66 can be ejected from the air ejection portion 67 by controlling the air ejection control valve 68 by the control portion 63.

[0061] like Figure 6 , Figure 8 , Fig. 9 as well as Fig.10 ( Fig.10 yes Figure 8 As shown in the enlarged view of the area AR in FIG. 1 , a Fig.11 The belt cover 70 shown. Fig.11 As shown, the belt cover 70 is composed of a plate-shaped member in this embodiment. The belt cover 70 is detachable relative to the main body 51, and when mounted on the main body 51, it covers at least the upper area of ​​the positioning sprocket 62B and the upper area of ​​the portion located between the positioning sprocket 62B and the discharge sprocket 62C in the conveying path 61 ( Figure 8 and Fig. 9 ).

[0062] Fig.12 and Fig.13 FIG. 2 shows a state where the belt cover 70 is mounted on the main body 51. Fig.13 It can be seen that the main body 51 of the tape feeder 16 includes two carrier tape support parts 51S extending along the YZ plane between the two side covers 51C and facing each other in the X direction, and the upper edges of the carrier tape support parts 51S serve as the aforementioned conveying surface 61M.

[0063] Thus, the conveying surface 61M is formed by the upper edges of the two carrier tape support parts 51S, and the two ends of the carrier tape CT are supported from below by the upper edges of the two carrier tape support parts 51S. Therefore, in this embodiment, not only a type without a portion protruding downward (so-called paper tape type) but also an embossed type with an embossed portion protruding downward can be used for the carrier tape CT.

[0064] exist Fig.11 The belt cover 70 includes a first belt pressing portion 71 constituting a central portion thereof, a second belt pressing portion 72 constituting a portion on the upstream side of the first belt pressing portion 71, and a third belt pressing portion 73 constituting a portion on the downstream side of the first belt pressing portion 71. The first belt pressing portion 71 and the second belt pressing portion 72 are connected by a connecting portion 74.

[0065] exist Fig.11 and Fig.13In the embodiment, a cover tape passage 75 is formed on the side of the connecting portion 74 (in the width direction of the tape cover 70, i.e., on the side of the X direction) by the gap between the first tape pressing portion 71 and the second tape pressing portion 72. The above-mentioned component removal opening 16K (also refer to Fig.12 ).

[0066] Thus, in this embodiment, the tape cover 70 is configured to cover the upper surface of the carrier tape CT transported by the carrier tape transport section 62, and has a component removal opening 16K formed at the component removal position 16T and a cover tape passage 75 formed by a gap formed at a position upstream away from the component removal opening 16K.

[0067] exist Fig.11 In the embodiment, a protruding piece 71H protruding toward the upstream side is formed at the upstream end of the first belt pressing portion 71, and the edge of the protruding piece 71H (that is, the upstream edge of the first belt pressing portion 71) serves as a stopper 76 (see also Fig.13 As described later, the stopper 76 has a function of blocking the leading portion SD of the cover tape TT of the carrier tape CT transported by the carrier tape transport portion 62 and guiding the leading portion SD upward (toward the upper surface side of the tape cover 70, the cover tape traction portion 111 described later) from the cover tape passage 75.

[0068] As described above, the second belt pressing portion 72 is connected to the upstream side of the first belt pressing portion 71 via the connecting portion 74. The downstream end of the second belt pressing portion 72 has a straight line shape extending in the X direction, and is disposed opposite to the stopper 76 at a gap (cover belt passage 75) at a predetermined interval, on the upstream side of the edge of the upstream side of the first belt pressing portion 71, i.e., on the upstream side of the stopper 76.

[0069] exist Fig.10 , Fig.11 , Fig.13 and Fig.14 In (a), the downstream side portion of the second belt pressing portion 72 is the contact portion 77, and the upstream side portion is the inclined portion 78. The contact portion 77 extends above the conveying surface 61M and parallel to the conveying surface 61M ( Fig.14 In (a)), the inclined portion 78 is a tapered surface 78M whose lower surface height from the conveying surface 61M gradually increases toward the upstream side (the distance from the conveying surface 61M decreases from the upstream toward the downstream).

[0070] exist Fig.14 In (a), when the carrier tape CT is not inserted into the conveying path 61, the lower surface of the second tape pressing portion 72 does not contact the conveying surface 61M, and a gap of size GP is formed between the lower surface of the second tape pressing portion 72 and the conveying surface 61M. Moreover, the size GP of the gap is larger than the thickness of the cover tape TT but smaller than the thickness TH of the carrier tape CT ( Fig.14Therefore, when the carrier tape CT enters between the contact portion 77 and the conveying surface 61M, the second tape pressing portion 72 is pushed upward due to the thickness of the carrier tape CT ( Fig.14 (b)).

[0071] That is, in the present embodiment, the second belt pressing portion 72 of the belt cover 70 is located at the upstream side of the cover tape passage 75 and the stopper 76, and functions as an upstream belt pressing portion pushed up by the carrier tape CT. It should be noted that the second belt pressing portion 72 only needs to have at least a portion of its lower surface that contacts the cover tape TT to be spaced apart from the conveying surface 61M by a distance GP upward, and other portions may contact the conveying surface 61M.

[0072] exist Fig.11 and Fig.10 In the embodiment, both ends of the third tape pressing portion 73 in the width direction (X direction) are bent portions 73R bent downward. Since the third tape pressing portion 73 has the bent portions 73R formed at both ends in the width direction, the bending rigidity in the vertical direction becomes high and is difficult to bend, so that the carrier tape CT near the component removal opening 16K can be reliably pushed toward the conveying surface 61M. On the other hand, the first tape pressing portion 71 connected to the upstream side of the third tape pressing portion 73 and the second tape pressing portion 72 connected to the upstream side of the first tape pressing portion 71 via the connecting portion 74 do not have a bent portion like the third tape pressing portion 73, and can be easily bent in the vertical direction.

[0073] exist Fig.11 and Fig.13 In the embodiment, a sprocket escape hole 73H is provided in the third belt pressing portion 73 of the belt cover 70 so as to extend in the Y direction. The sprocket escape hole 73H has a function of preventing interference between the feed pin 62P of the positioning sprocket 62B and the belt cover 70 .

[0074] In addition, if Fig.11 and Fig.13 As shown, a component discharge opening 70S is provided at the end (downstream end 70F) of the third tape pressing portion 73 of the tape cover 70. The component discharge opening 70S is a groove-shaped opening extending in a slit-like manner along the Y direction from the downstream side of the component removal opening 16K to the downstream side edge of the tape cover 70. The component discharge opening 70S is provided in order to reliably discharge the component BH remaining on the carrier tape CT due to the failure of the mounting head 13 to remove the component BH supplied to the component removal opening 16K. That is, the component discharge opening 70S functions as a passage for the component BH, and the passage for the component BH is used to discharge the component BH to the outside of the tape feeder 16 in a manner that does not interfere with the tape cover 70 even if the component BH remains in an upright posture and a part of it protrudes from the upper surface of the carrier tape CT.

[0075] The dimension of the component discharge opening 70S in the width direction (X direction) horizontally intersecting the conveying direction of the carrier tape CT is narrower than the width dimension of the component extraction opening 16K, and a guide portion 70T having a tapered shape with a cut corner is formed at the connection portion between the component extraction opening 16K and the component discharge opening 70S. Therefore, the connection portion between the component extraction opening 16K and the component discharge opening 70S gradually narrows as it moves downstream in the conveying direction of the carrier tape CT. By providing such a guide portion 70T, the tape cover 70 guides the component BH dropped into the component extraction opening 16K to the component discharge opening 70S using the guide portion 70T, thereby avoiding conveying failures caused by the component BH being sandwiched between the carrier tape CT and the tape cover 70.

[0076] exist Fig.11 , Fig.12 as well as Fig.13 In the embodiment, a pair of protrusions 79 are provided in the middle of the tape cover in the Y direction, extending protrudingly to both sides along the width direction (X direction) of the tape cover 70. That is, in the present embodiment, the tape cover 70 is configured to have the protrusions 79 protruding from the middle portion thereof to both sides along the direction (X direction) horizontally intersecting the conveying direction of the carrier tape CT.

[0077] exist Figure 7 , Fig.10 as well as Fig.12 In the embodiment, a pair of guide grooves 51G formed of longitudinally long U-shaped grooves are formed at the upper edges of the pair of side covers 51C constituting the main body 51. The pair of protrusions 79 ( Fig.10 and Fig.12 ). The protrusion 79 engaged with the guide groove 51G is allowed to move in the vertical direction within the guide groove 51G, and can move up and down along the guide groove 51G.

[0078] That is, in the present embodiment, the guide groove 51G as the belt cover holding portion is a longitudinal groove that guides the protrusion 79 of the belt cover 70 in the up-down direction, and becomes a belt cover holding portion that engages with the protrusion 79 and holds the belt cover 70 so as to be freely displaceable in the up-down direction.

[0079] exist Figure 7 and Fig.12 In the embodiment, the upper ends of the guide grooves 51G of the pair of side covers 51C are formed into openings 51H that are opened upward. In addition, the upper edges of the side covers 51C located on the downstream side of the guide grooves 51G are formed into inclined surfaces 51Y that gently descend toward the upstream side, and the lower ends (ends on the upstream side) are connected to the upper edges of the downstream side of the guide grooves 51G ( Figure 7 , Fig.10 as well as Fig.12 ).

[0080] When the pair of protrusions 79 of the belt cover 70 are engaged with the pair of guide grooves 51G of the side cover 51C, the belt cover 70 as a whole is moved toward the upstream side in a state where the protrusions 79 are in contact with the inclined surface 51Y. As a result, the protrusions 79 move toward the upstream side (descend) along the inclined surface 51Y, fall into the guide grooves 51G at the end of the inclined surface 51Y, and engage with the guide grooves 51G.

[0081] Thus, in the present embodiment, an opening portion 51H whose upper portion is open is formed in the upper portion of the guide groove 51G provided in the side cover 51C constituting the main body 51 so as to allow the protrusion 79 of the belt cover 70 to enter and exit, and an inclined surface 51Y formed by the upper edge of the side cover 51C reaching the opening portion 51H serves as a belt cover guide portion for guiding the protrusion 79 to the guide groove 51G. In addition, in the present embodiment, the guide groove 51G formed in the side cover 51C holds the protrusion 79 of the engaged belt cover 70 so as to be freely displaceable in the up-down direction.

[0082] exist Figure 8 and Fig. 9 In the embodiment, a tape cover pressing portion (a front pressing portion 81, a middle pressing portion 82, and a rear pressing portion 83) is provided at the front upper portion of the main body portion 51. The tape cover pressing portion has the following function: by applying force to the tape cover 70 toward the conveying surface 61M, the tape cover 70 is used to press the carrier tape CT traveling on the conveying surface 61M, thereby pressing the carrier tape CT onto the conveying surface 61M.

[0083] like Fig.12 as well as Fig.15 As shown in (a) and (b) of FIG. 1 , the front pressing portion 81 includes a base portion 81a, a pressing plate 81b, and a first coil spring 81c (see also Figure 8 as well as Fig. 9 ).like Fig.12 and Fig.15 As shown in (a) and (b) of FIG. 1 , a front end block 51B having a carrier tape guide 51D for guiding the carrier tape CT downward is provided at the front end of the main body 51 (see also FIG. 1 ). Figure 8 and Fig. 9 ), the seat portion 81a is mounted on the front end block 51B. Specifically, the seat portion 81a is mounted to be swingable relative to the front end block 51B (i.e., relative to the main body 51) by supporting pins 81d extending in the X direction (a direction horizontally intersecting the conveying direction of the carrier tape CT) and supported at both ends by the front end block 51B.

[0084] exist Fig.15In (a) and (b), a pair of side wall portions 91 extending upward and facing each other in the X direction are provided on the upper portion of the base portion 81a. A receiving portion 92 extending in the X direction is provided between the pair of side wall portions 91, and a pressing claw 93 extending in the X direction in a cantilever state is provided on one side of the pair of side wall portions 91. The pressing claw 93 is located on the upstream side of the receiving portion 92 ( Fig.15 (a)).

[0085] exist Fig.12 and Fig.15 In (a) and (b), the pressing plate 81b is composed of a plate-shaped member extending in the Y direction. Fig.15 As shown in (a) and (b) of FIG. 81 , the pressing plate 81 b includes a pressing portion 94 having a long hole-shaped escape portion 94H extending in the Y direction, and an assembly portion 95 formed by a portion on the downstream side of the pressing portion 94. The dimension of the assembly portion 95 in the width direction (X direction) is smaller than the dimension of the width direction of the pressing portion 94, and the end surface on the downstream side of the step portion formed at the boundary between the pressing portion 94 and the assembly portion 95 serves as a pressing portion side positioning surface 95M ( Fig.15 (a)).

[0086] exist Fig.12 and Fig.15 In (a) and (b), the first coil spring 81c is provided between the base portion 81a and the main body portion 51 (see also Figure 8 and Fig. 9 The first coil spring 81 c applies force in a direction to push the seat portion 81 a upward relative to the main body portion 51 .

[0087] exist Fig.12 and Fig.15 In (b), the mounting portion 95 of the pressing plate 81b mounted on the pedestal portion 81a is located between the pair of side wall portions 91 of the pedestal portion 81a. Furthermore, the pressing portion side positioning surface 95M is formed from the upstream side to the downstream end surface of one side wall portion 91, that is, the pedestal side positioning surface 91M ( Fig.15 The receiving portion 92 is pushed upward by the first coil spring 81c, and the middle portion of the pressing plate 81b in the Y direction is pressed against the lower surface of the pressing claw 93 from below ( Fig.15 (b)).

[0088] The pressing plate 81b mounted on the pedestal 81a swings together with the pedestal 81a about the support pin 81d by the first coil spring 81c, and the upstream end portion of the pressing plate 81b, i.e., the rear end portion 94T ( Fig.12 and Fig.15 (a), (b)) The downstream end portion 70F of the belt cover 70 is pressed downward ( Figure 8 and Fig. 9The third tape pressing portion 73 is in a state where the carrier tape CT inserted into the conveying path 61 has not reached the bottom of the tape cover 70 (referred to as an "initial state"). Figure 8 and Fig.10 ) is pressed downward by the front pressing portion 81, so that the lower surface comes into contact with the conveying surface 61M.

[0089] Thus, in the present embodiment, the front pressing portion 81 as the tape cover pressing portion includes: a seat portion 81a that swings around a support pin 81d as a swing axis (a swing axis extending in the X direction) horizontally intersecting the conveying direction of the carrier tape CT; a pressing plate 81b that is detachable from the seat portion 81a; and a first coil spring 81c as an elastic member that urges the seat portion 81a in one direction (upward in this case) to swing the seat portion 81a, thereby pressing the pressing plate 81b mounted on the seat portion 81a against the upper surface of the downstream end portion 70F of the tape cover 70. Furthermore, the seat portion 81a includes a receiving portion 92 that supports the lower surface of the pressing plate 81b; and a pressing claw 93 that presses the upper surface of the pressing plate 81b supported by the receiving portion 92, and the front pressing portion 81 presses the downstream end portion 70F of the tape cover 70 downward.

[0090] As described above, a slit-shaped component discharge opening 70S is formed at the downstream end 70F of the belt cover 70, and the downstream end 70F is in a shape divided into two parts. The pressing plate 81b of the front pressing portion 81 abuts against the downstream end 70F of the shape divided into two parts in a manner that spans the downstream end 70F of the belt cover 70, and the two-part part is in a state where the pressing plate 81b is applied force downward. Therefore, the rigidity of the downstream end 70F of the belt cover 70 is reduced due to the component discharge opening 70S, but the front pressing portion 81 of the present embodiment presses from the upper surface of the downstream end 70F, so that the pushing force is used to avoid the situation where the downstream end 70F is deformed and cannot stably push the carrier tape CT. As a result, the carrier tape CT can be stably transported at the downstream end 70F of the belt cover 70.

[0091] As described above, in the present embodiment, the tape cover 70 has the component discharge opening 70S formed continuously from the component extraction opening 16K to the downstream end portion 70F, and the pressing plate 81 b of the front pressing portion 81 is provided to cover the component discharge opening 70S.

[0092] In this embodiment, as described above, the pressing plate 81b is detachable relative to the base portion 81a, and its rear end portion 94T has a shape that can be used as a tool. Fig.15As shown in (a) and (b), the pressing plate 81b is formed into a straight line. Therefore, the pressing plate 81b can be used as a tool (such as a screwdriver) for the tape feeder 16. That is, in this embodiment, the end of the pressing plate 81b functions as a tool used for the tape feeder 16.

[0093] exist Figure 8 , Fig. 9 as well as Fig.10 The middle pressing portion 82 is disposed on the upper surface of the middle portion of the belt cover 70 and is located upstream of the protrusion 79. Figure 7 As shown, the middle pressing portion 82 includes a spring holding portion 82a, a torsion spring 82b, and a pressing roller 82c. The spring holding portion 82a is composed of an axial member that is supported at both ends by a pair of side covers 51C constituting the main body 51 and extends in the X direction ( Figure 7 ).

[0094] exist Figure 7 , Fig.10 and Fig.12 The helical portion of the torsion spring 82b is inserted through the spring holding portion 82a. The torsion spring 82b is held by the spring holding portion 82a by being locked by the upstream side extending portion extending upstream and a pin (not shown) fixed to the side cover 51C.

[0095] exist Figure 7 In the embodiment, the pressing roller 82c is composed of a roller member extending in the X direction, and both ends are supported by the two side covers 51C. Specifically, the pressing roller 82c is located in the pressing roller guide holes 51N extending in the vertical direction in the two side covers 51C, and is rotatable around an axis along the width direction (X direction) of the belt cover 70, and is guided by the pressing roller guide holes 51N to move vertically (see also Fig.10 and Fig.12 ).

[0096] That is, in the present embodiment, the pressing roller 82 c is formed of a roller having a rotation axis oriented in the width direction of the tape cover 70 (a direction horizontally intersecting the conveyance direction of the carrier tape CT, the X direction).

[0097] exist Fig.10 , Fig.12 and Fig.13 In the embodiment, the pressing roller 82c is located in the middle of the belt cover 70 in the Y direction and is sandwiched between the component removal opening 16K and the cover belt passage 75 (specifically, on the upstream side of the protrusion 79 in the first belt pressing portion 71). Figure 7 As shown, the pressing roller 82c is urged downward by the downstream extension of the torsion spring 82b, so that the middle portion of the belt cover 70 (the first belt pressing portion 71) is pressed toward the conveying surface 61M by the torsion spring 82b via the pressing roller 82c ( Figure 8 , Fig. 9 as well as Fig.10 In the initial state where the carrier tape CT inserted into the conveying path 61 has not reached below the tape cover 70, the second tape pressing portion 72 is urged downward by the middle pressing portion 82 so that the lower surface abuts against the conveying surface 61M ( Fig.10 ).

[0098] Thus, in the present embodiment, the middle pressing portion 82 is configured to include: a pressing roller 82c as a pressing member, which presses the upper surface of the middle portion of the belt cover 70, that is, the portion in the direction (X direction) horizontally intersecting the conveying direction of the carrier tape CT, into a linear shape; and a torsion spring 82b as an elastic member, which pushes the pressing roller 82c downward. Moreover, the pressing roller 82c is arranged upstream of the protrusion 79 arranged in the middle portion of the belt cover 70 in the Y direction, and the middle pressing portion 82 as the belt cover pressing portion pushes the middle portion of the belt cover 70 (near the protrusion 79) downward.

[0099] As described above, in this embodiment, not only the downstream end portion 70F ( Figure 7 and Fig.10 ) is pushed downward, and the middle portion of the tape cover 70 in the Y direction (near the protrusion 79) is also pushed downward. Therefore, in the tape feeder 16 of this embodiment, the carrier tape CT near the component removal position 16T can be moved while being pushed toward the conveying surface 61M with an appropriate pressing force, and the component BH at the component removal position 16T can be accurately positioned. Furthermore, the occurrence of a pick-up error of the component BH by the mounting head 13 can be prevented.

[0100] exist Figure 8 , Fig. 9 and Fig.16 In the embodiment, the rear pressing portion 83 includes a rear pressing rod 101 and a second coil spring 102. The rear pressing rod 101 is provided to extend in the Y direction at the upper portion of the main body 51 (specifically, the upper region of the introduction sprocket 62A). The middle portion in the Y direction of the rear pressing rod 101 is supported by a rod swing shaft 103 extending in the X direction, and includes an upstream extension portion 101a extending from the rod swing shaft 103 to the upstream side and a downstream extension portion 101b extending to the downstream side ( Fig.16 ).

[0101] exist Fig.16In the embodiment, the front end portion of the downstream extension portion 101b of the rear pressing rod 101 is bent and extended downward. And the front end portion of the bent and extended portion, i.e., the rod front end portion 101c, is located above the second belt pressing portion 72. The second coil spring 102 applies force to the upstream extension portion 101a of the rear pressing rod 101 upward, i.e., in a direction away from the conveying surface 61M. Therefore, the rod front end portion 101c of the rear pressing rod 101 is applied downward, i.e., in a direction toward the conveying surface 61M.

[0102] exist Fig.16 In the embodiment, the rear pressing lever 101 is limited in its rotation range by a limiting pin 101P fixed to the main body 51. In the initial state where the carrier tape CT has not reached below the tape cover 70, the front end portion 101c of the lever does not contact the tape cover 70 and is located at a position separated from the upper surface of the inclined portion 78 by a gap smaller than the thickness of the carrier tape CT ( Fig.14 (a)).

[0103] As described above, the pair of protrusions 79 of the belt cover 70 are located in the pair of guide grooves 51G which are longitudinal grooves provided in the main body 51. Therefore, the belt cover 70 can swing freely with the pair of protrusions 79 as a fulcrum (see Fig.17 ), and can move in the up and down directions (lift and lower) ( Fig.17 Therefore, when the front end ST of the carrier tape CT enters between the tape cover 70 and the conveying surface 61M, the tape cover 70 is lifted as a whole due to the thickness of the carrier tape CT, and is in a state where it is urged downward by the rear pressing portion 83 in addition to the front pressing portion 81 and the middle pressing portion 82 (described later).

[0104] In this state, the vertical displacement of the protrusion 79 in contact with the guide groove 51G is small (equivalent to the thickness TH of the carrier tape CT), and the upstream end 70A of the tape cover 70 ( Fig.11 and Fig.13 ), the downstream end 70F easily follows the thickness TH of the carrier tape CT and moves in the vertical direction. Therefore, in this embodiment, the smooth movement of the tape cover 70 can be ensured, and the carrier tape CT being conveyed can be stably pressed against the conveying surface 61M.

[0105] like Fig.14 As shown in (b), when the front end ST of the carrier tape CT reaches below the contact portion 77 and the second tape pressing portion 72 (more specifically, the contact portion 77) of the tape cover 70 is lifted by the carrier tape CT, the inclined portion 78 of the second tape pressing portion 72 abuts against the rod front end portion 101c ( Fig.14 (a) → Fig.14 As a result, the second tape pressing portion 72 is pressed toward the carrier tape CT by the second coil spring 102 via the rear pressing rod 101 .

[0106] Thus, in the present embodiment, the rear pressing rod 101 of the rear pressing portion 83 is a member that swings around a horizontal axis (rod swing axis 103) that is orthogonal to the conveying direction of the carrier tape CT, and the second coil spring 102 applies one end of the rear pressing rod 101 to the upper surface of the tape cover 70. It should be noted that the reason why the rod front end 101c is spaced upward without contacting the tape cover 70 in the initial state where the carrier tape CT has not reached the bottom of the tape cover 70 is to reduce the resistance when the carrier tape CT lifts the second tape pressing portion 72, and to prevent the carrier tape CT from buckling when the second tape pressing portion 72 is lifted.

[0107] When the belt cover 70 is mounted on the main body 51, first, the upstream end 70A of the belt cover 70 is inserted into the insertion space 82S ( 82S ) formed between the conveying surface 61M and the pressing roller 82c, while being inclined so that the upstream end 70A of the belt cover 70 is lower than the downstream end 70F. Figure 7 and Fig.18 )( Fig.18 After inserting the upstream end 70A of the belt cover 70 into the insertion space 82S, the operator inserts the pair of protrusions 79 of the belt cover 70 from above (from the opening 51H) into the pair of guide grooves 51G provided in the main body 51 ( Fig.18 Y2 as shown in the figure).

[0108] At this time, the operator slides the belt cover 70 to the upstream side while the pair of protrusions 79 are in contact with the corresponding inclined surfaces 51Y from above. As a result, each protrusion 79 moves to the upstream side on the inclined surface 51Y and descends, and falls into the guide groove 51G at the end of the inclined surface 51Y and is inserted. The protrusion 79 is restricted from moving in the front-rear direction (Y direction) by being inserted into the guide groove 51G, and is positioned relative to the main body 51. Therefore, the operator can easily install the belt cover 70 on the main body 51 (side cover 51C).

[0109] When the belt cover 70 is positioned relative to the main body 51 as described above, the pressing roller 82c contacts the middle portion of the belt cover 70 in the Y direction (specifically, a position slightly upstream of the pair of protrusions 79) from above. In this state, the belt cover 70 is in a posture along the conveying surface 61M, and the upstream end 70A of the belt cover 70 is in a substantially horizontal posture ( Fig.19 ). Then, the operator finally mounts the pressing plate 81b on the base portion 81a.

[0110] In order to attach the pressing plate 81b to the pedestal 81a, the operator first presses the pedestal 81a downward to make the pedestal 81a in a position where the pressing plate 81b can be attached. The operator maintains this state and moves the attachment portion 95 of the pressing plate 81b with its downstream end, i.e., the front end 95T ( Fig.15 A. Fig.15 (a), (b)) are inserted into the space below the pressing claw 93 toward the upstream side ( Fig.15 (a) → Fig.15 (b). Fig.19 Y3).

[0111] As a result, the mounting portion 95 of the pressing plate 81b reaches above the receiving portion 92, and the pressing portion side positioning surface 95M abuts against the pedestal side positioning surface 91M from the upstream side ( Fig.15 After (b), the operator releases the downward pressing state of the seat portion 81a. As a result, the pressing plate 81b swings in the direction of lowering the rear end portion 94T by the pressing claw 93 of the seat portion 81a swinging with the help of the first coil spring 81c, and presses the downstream end portion 70F of the belt cover 70 downward. Therefore, the downstream end portion 70F of the belt cover 70 is pressed toward the main body 51 by the front pressing portion 81. As a result, the assembly of the belt cover 70 to the main body 51 is completed ( Fig.12 ).

[0112] Thus, in the tape feeder 16 of the present embodiment, the tape cover pressing portion that pushes the tape cover 70 toward the carrier tape CT includes a front pressing portion 81 that presses the downstream end portion of the tape cover 70. The front pressing portion 81 is configured to include a base portion 81a that is swingable relative to the main body portion 51, a pressing plate 81b that is detachable relative to the base portion 81a, and a first coil spring 81c that is an elastic member that urges the base portion 81a in one direction (upward).

[0113] In the present embodiment, one end side (the upstream end side 70A side) of the belt cover 70 is inserted into the insertion space 82S on the main body 51 side to be installed on the main body 51, and the other end side (the downstream end side 70F) is installed on the main body 51 by being pressed by the rod member (the pressing plate 81b) urged by the first coil spring 81c. Therefore, in the present embodiment, the belt cover 70 can be easily attached to and detached from the main body 51.

[0114] When the tape cover 70 is attached to the main body 51 as described above, when the carrier tape CT enters between the tape cover 70 and the conveying surface 61M from the upstream side, the upstream end 70A (second tape pressing portion 72) of the tape cover 70 is first lifted due to the thickness of the front end ST of the carrier tape CT. Fig.17 The protrusion 79 slightly rises in the guide groove 51G ( Fig.14 (a) → Fig.14 (b)).

[0115] When the carrier tape CT further moves and the front end ST of the carrier tape CT reaches below the protrusion 79 of the belt cover 70, the middle portion thereof is pushed up by the carrier tape CT and rises away from the conveying surface 61M. When the carrier tape CT further moves and reaches below the downstream end 70F, the belt cover 70 moves upward. Fig.17 The third tape pressing portion 73 is swung counterclockwise, and the third tape pressing portion 73 is in a posture substantially parallel to the conveying surface 61M. While the carrier tape conveying portion 62 is positioning the carrier tape CT toward the component removal opening 16K, the tape cover 70 maintains this posture, but when the rear end (not shown) of the carrier tape CT passes through the protrusion 79 of the tape cover 70, the tape cover 70 moves in a direction that lowers the upstream end 70A, i.e., Fig.17 Then, when the rear end of the carrier tape CT is completely pulled out from between the tape cover 70 and the conveying surface 61M, the tape cover 70 moves to the Fig.17 The second belt pressing portion 72 and the third belt pressing portion 73 are respectively in contact with the conveying surface 61M ( Fig.10 ).

[0116] As described above, in the tape feeder 16 of the present embodiment, a pair of protrusions 79 provided in the middle portion of the tape cover 70 engage with the guide groove 51G as the tape cover holding portion from the open portion 51H provided in the side cover 51C constituting the main body 51, so as to be held to be freely displaceable in the up-down direction relative to the main body 51 (specifically, the side cover 51C). In such a structure, the pair of protrusions 79 in the middle portion of the tape cover 70 engage with the guide groove 51G to achieve positioning in the conveying direction of the carrier tape CT, and are held to be freely displaceable in the up-down direction. On the other hand, the upstream side end 70A and the downstream side end 70F of the tape cover 70 become free ends that are not positioned in the conveying direction of the carrier tape CT, and can be displaced in the up-down direction with the protrusion 79 as the center. Therefore, the tape cover 70 can smoothly change its posture according to the position of the carrier tape CT. Moreover, the displacement of the middle portion of the tape cover 70 in the up-down direction is smaller than that of the upstream side end 70A and the downstream side end 70F, and is the thickness TH of the carrier tape CT. Therefore, when the belt cover 70 is pushed to the downstream side due to friction during the transportation of the carrier tape CT, friction resistance is generated between the protrusion 79 and the guide groove 51G, but the displacement of the middle portion including the protrusion 79 in the up-down direction is small, so the posture change of the belt cover 70 is almost not affected by the friction resistance and is smoothly performed. In addition, since the belt cover 70 can swing around the protrusion 79, the upstream end 70A and the downstream end 70F are also almost not affected by the friction resistance and are smoothly displaced. Therefore, in this embodiment, the smooth movement of the belt cover 70 can be ensured, and the carrier tape CT being transported can be stably pushed.

[0117] In addition, the tape cover 70 of the present embodiment does not include a peeling knife (blade) for peeling the cover tape TT from the carrier tape CT as in Patent Document 1, so that the thrust for pushing the tape cover 70 to the downstream side can be reduced, thereby reducing the friction resistance between the protrusion 79 and the guide groove 51G, and preventing damage caused by wear caused by the vertical movement of the tape cover 70. Therefore, it is not easy to cause poor sliding and fixing relative to the guide groove 51G due to wear of the protrusion 79 (i.e., the movable part of the tape cover 70).

[0118] exist Figure 8 , Fig. 9 , Fig.10 and Fig.16 In the embodiment, a cover tape pulling section 111 is provided at a position upstream of the component taking-out position 16T. The cover tape pulling section 111 has a function of pulling upward the cover tape TT peeled off from the carrier tape CT.

[0119] exist Fig.16 In the embodiment, the cover tape pulling section 111 is composed of a driving roller 111a and a driven roller 111b having a smaller diameter than the driving roller 111a and located at the downstream side of the driving roller 111a. The driving roller 111a is in contact with the driven roller 111b. When the driving roller 111a moves to Fig.16 When the driven roller 111b rotates in the counterclockwise direction, the driven roller 111b rotates in the clockwise direction by the driving roller 111a.

[0120] The driving roller 111a is driven by the sprocket driving motor 62D via a transmission gear mechanism (not shown). Therefore, the driving roller 111a is driven at the same timing as the carrier tape conveying unit 62. The cover tape TT pulled by the cover tape pulling unit 111 is discharged to the cover tape discharge path 65 and recovered as described above.

[0121] Next, the supply operation of the component BH by the tape feeder 16 will be described. When the component BH is supplied to the component removal position 16T by conveying the carrier tape CT by the tape feeder 16, the operator first manually inserts the front end ST of the carrier tape CT into the carrier tape introduction port 61A after setting the leading portion SD to extend from the front end of the carrier tape CT through the aforementioned steps. Then, the carrier tape CT is pushed in toward the downstream side until the feed hole KH of the front end ST of the carrier tape CT engages with the feed pin 62P of the introduction sprocket 62A.

[0122] When the carrier tape CT is inserted from the carrier tape introduction port 61A so that the feed hole KH near the front end ST of the carrier tape CT engages with the feed pin 62P of the introduction sprocket 62A, this is detected by a sensor not shown. After the sensor detects that the feed hole KH of the carrier tape CT engages with the feed pin 62P of the introduction sprocket 62A, the control unit 63 operates the sprocket drive motor 62D to rotate the three sprockets (the introduction sprocket 62A, the positioning sprocket 62B, and the discharge sprocket 62C). Alternatively, the operator inserts the carrier tape CT from the carrier tape introduction port 61A so that the feed hole KH engages with the feed pin 62P of the introduction sprocket 62A, and operates the operation switch of the tape feeder 16 to operate the sprocket drive motor 62D to rotate the three sprockets. Thus, the carrier tape conveying unit 62 starts conveying the carrier tape CT, and the carrier tape CT moves toward the downstream side on the conveying surface 61M. It should be noted that at this time, the second belt pressing portion 72 and the third belt pressing portion 73 of the belt cover 70 are in contact with the conveying surface 61M ( Fig.10 ).

[0123] like Fig. 20 As shown in the figure, the front end ST of the carrier tape CT moving toward the downstream side on the conveying surface 61M starts with the leading portion SD of the cover tape TT and enters the space between the conveying surface 61M and the lower surface of the contact portion 77 of the second tape pressing member 72. When the carrier tape CT moves further, the front end of the leading portion SD of the cover tape TT, that is, the leading portion front end SS (also refer to Figure 3 (a) and Figure 4 When the leading portion SD is prevented from moving further downstream, the leading end SS of the leading portion of the cover tape TT passes upward through the cover tape passage 75 and protrudes toward the upper side of the second tape pressing portion 72 (i.e., the tape cover 70) ( Fig.21 ).

[0124] In this way, the stop portion 76 of the first belt pressing portion 71 has the following function: when the first belt pressing portion 71 is in contact with the conveying surface 61M, the front end SS of the leading portion of the cover belt TT coming from the upstream side is blocked so as not to enter between the first belt pressing portion 71 and the conveying surface 61M.

[0125] As described above, the control unit 63 controls the air ejection control valve 68 at the timing when the leading end SS of the cover tape TT reaches the cover tape passage 75 of the tape cover 70 (or is about to reach it), so that the air 107 is ejected upward from the air ejection unit 67 ( Fig.21 The air ejection unit 67 is disposed at a position where the ejected air 107 passes through the cover tape passage 75 from below. When the air ejection unit 67 ejects the air 107, the air 107 passes through the cover tape passage 75 from below.

[0126] Therefore, when the leading end SS of the cover tape TT reaches the cover tape passage 75, the air 107 is ejected from the air ejection unit 67, and the leading end SS of the cover tape TT is guided by the flow of the air 107 ejected from the air ejection unit 67, and passes through the cover tape passage 75 upward to protrude above the tape cover 70. Then, the carrier tape CT moves upward as it moves toward the downstream side, and reaches between the driving roller 111a and the driven roller 111b constituting the cover tape traction unit 111 ( Fig. 22 ).

[0127] The leading end SS of the cover tape TT that reaches between the driving roller 111a and the driven roller 111b is caught by the cover tape traction unit 111 (due to the opposite rotation of the driving roller 111a and the driven roller 111b) and is pulled upward ( Fig.23 ).

[0128] As described above, after the leading portion SD of the cover tape TT passes upward through the cover tape passage 75, the leading end ST of the carrier tape CT abuts against the tapered surface 78M of the second tape pressing portion 72 ( Fig.21 If the carrier tape CT whose front end ST is in contact with the tapered surface 78M is moved further downstream, the second tape pressing portion 72 is pushed upward by the carrier tape CT ( Fig.21 → Fig. 22 ).

[0129] The second tape pressing portion 72 pushed upward by the carrier tape CT pulls the first tape pressing portion 71 upward via the connecting portion 74. Therefore, a gap G ( 20 ) is formed between the first tape pressing portion 71 and the conveying surface 61M through which the carrier tape CT can travel. Fig. 22 ), the upstream edge of the first tape pressing portion 71, i.e., the stopper 76, also rises from the conveying surface 61M. After a gap of interval G is formed between the first tape pressing portion 71 and the conveying surface 61M, the carrier tape CT moves downstream in the gap ( Fig. 22 → Fig.23 ).

[0130] Thus, as described above, the second tape pressing portion 72 is an upstream tape pressing portion that is located on the upstream side of the cover tape passage 75 and is pushed upward by the carrier tape CT, and becomes a contact displacement portion that is displaced by contacting the carrier tape CT, and the connecting portion 74 becomes a transmission portion that transmits the displacement of the second tape pressing portion 72 as the contact displacement portion to the first tape pressing portion 71 to displace the stopper 76. Furthermore, the second tape pressing member 72 as the contact displacement portion and the connecting portion 74 as the transmission portion become a height changing portion that lifts the stopper 76 upward from the conveying surface 61M.

[0131] As described above, when the second belt pressing portion 72 is pushed upward by the carrier tape CT, the inclined portion 78 of the second belt pressing portion 72 abuts against the rod front end portion 101c of the rear pressing portion 83 from below, pushing the rod front end portion 101c upward. As a result, the second coil spring 102 of the rear pressing portion 83 is compressed by the upstream extension portion 101a of the rear pressing rod 101, and its reaction force applies force to the upstream extension portion 101a upward. Therefore, the second belt pressing member 72 (inclined portion 78) is applied downward by the second coil spring 102 via the rear pressing rod 101 ( Fig. 9 and Fig.24 The pressing force shown in F3).

[0132] Thus, in this embodiment, when the carrier tape CT is not in the conveying path 61, the rear pressing portion 83 and the rear pressing rod 101 are in non-contact with the tape cover 70, and the rear pressing portion 83 contacts the tape cover 70 (specifically, the second tape pressing portion 72) that has been displaced upward with the aid of the carrier tape CT and presses it downward.

[0133] When the carrier tape CT moves toward the downstream side in the gap formed between the lower surface of the first tape pressing portion 71 and the conveying surface 61M, the cover tape TT extending upward through the cover tape passage 75 is further pulled upward (inside the cover tape discharge path 65) by the cover tape pulling portion 111 ( Fig.24 → Fig.25 ).

[0134] As described above, in the present embodiment, the cover tape pulling section 111 is configured to pull the cover tape TT peeled off from the carrier tape CT.

[0135] In this embodiment, the tape cover 70 and the cover tape pulling portion 111 constitute the aforementioned cover tape peeling portion 64 ( Figure 8 , Fig. 9 and Fig.10 The cover tape peeling section 64 is disposed upstream of the component removal position 16T, and has the function of catching and pulling the leading portion SD of the cover tape TT extending downstream from the leading end ST of the carrier tape CT, and feeding it into the cover tape discharge path 65 .

[0136] The carrier tape CT from which the cover tape TT has been peeled off by the cover tape peeling unit 64 is conveyed by the carrier tape conveying unit 62 to the downstream side on the conveying path 61, so that the first component storage recess PK in the carrier tape CT is positioned at the component removal position 16T. Thus, the positioning process of the carrier tape CT is completed. The carrier tape conveying unit 62 performs the operation (positioning process of the carrier tape CT) without stopping until the first component storage recess PK is positioned at the component removal position 16T.

[0137] During the positioning process, the cover tape TT is peeled off from the carrier tape CT by the cover tape peeling unit 64. Then, as the mounting head 13 of the component mounting device 1 sucks and takes out the component BH (pick-up operation), the pitch feeding based on the carrier tape conveying unit 62 is performed, and the component storage recess PK is sequentially positioned at the component taking-out position 16T (carrier tape positioning operation).

[0138] Thus, in this embodiment, the tape feeder 16 as a component supply device is configured to peel off the cover tape TT having a leading portion SD extending from the front end of the carrier tape CT from the carrier tape CT, thereby exposing the component BH accommodated in the carrier tape CT in a state covered by the cover tape TT, and transport the exposed component BH to the component removal position 16T and supply it to the component mounting device 1.

[0139] When the component mounting device 1 having the above-mentioned structure with the tape feeder 16 performs a component mounting operation of mounting the component BH on the substrate KB, first, the substrate KB supplied from the outside of the component mounting device 1 is carried in by the substrate conveying unit 12 and positioned at a predetermined operating position. After the substrate KB is positioned at the operating position, each tape feeder 16 supplies the component BH to the component taking-out opening 16K, and the mounting head 13 holds and takes out the component BH from the component taking-out position 16T of the tape feeder 16 through the component holding nozzle 14.

[0140] The mounting head 13 that has taken out the component BH from the component taking-out position 16T of the tape feeder 16 moves above the substrate KB and mounts the component BH at the target component mounting position determined on the substrate KB. After all the components BH to be mounted on the substrate KB are mounted, the substrate KB is carried out to the outside of the component mounting device 1 by the substrate transport unit 12. Thus, the component mounting operation of one substrate KB is completed.

[0141] As described above, in the component supply device (tape feeder 16) of the present embodiment, even if the posture of the tape cover 70 changes according to the position of the carrier tape CT, the relative movement portion of the tape cover 70 with respect to the side cover 51C is only a small displacement of the pair of protrusions 79 with respect to the guide groove 51G in the vertical direction (the degree of the thickness TH of the carrier tape CT), and the two ends of the tape cover 70 in the longitudinal direction do not slide with respect to the main body 51 as in the past. Therefore, it is possible to ensure smooth movement of the tape cover 70 and stably push the carrier tape CT being transported. In addition, the displacement amount of the pair of protrusions 79 when sliding in the vertical direction with respect to the guide groove 51G is extremely small, and damage caused by wear caused by the vertical movement of the tape cover 70 can be suppressed. Therefore, it is possible to suppress the occurrence of poor sliding and fixing with respect to the guide groove 51G due to wear of the protrusions 79 (i.e., the movable part in the tape cover 70).

[0142] The embodiments of the present invention have been described so far, but the present invention is not limited to the above contents, and various modifications are possible. For example, in the above embodiments, the tape feeder 16 is a structure that blows the leading portion SD of the cover tape TT protruding from the front end ST of the carrier tape CT upward by air to capture and lift it so as to be peeled off from the carrier tape CT, but the tape feeder 16 to which the present invention is applied is not necessarily a structure that peels off the cover tape TT in such a process.
