Description

[Technical Field]

[0001] The present invention relates to a component mounting device and a carriage that removes components from a carrier tape and mounts them on a substrate. [Background technology]

[0002] Conventionally, component mounting devices that mount components onto a substrate are known. The component mounting device includes a substrate holding unit that holds the substrate and a work head that picks up components from a component supply unit and mounts them onto the substrate. A tape feeder that uses a carrier tape containing multiple components arranged in a row is often used as the component supply unit that supplies the components to the component supply unit.

[0003] A component mounting device that uses tape feeders as component supply units includes a feeder base that holds multiple component supply units in a line, and a carrier tape cutting device that cuts the carrier tape into strips after components have been removed by a work head. Because the carrier tape discharged from the component supply units must be reliably introduced into the carrier tape cutting device, the carrier tape cutting device and the feeder base are often either provided as a set on the base (see Patent Document 1 below) or on a carriage that is attached to the base (see Patent Document 2 below). The carriage is detachable from the base and includes a feeder base, so that multiple component supply units can be attached to the base all at once by attaching the carriage to the base with multiple component supply units attached to the feeder base.

[0004] In the former type, where the feeder base and carrier tape cutting device are mounted as a set on the base, maintenance is easy because only one carrier tape cutting device is mounted on the base, but multiple component supply units cannot be replaced all at once.On the other hand, in the latter type, where the feeder base and carrier tape cutting device are mounted as a set on the carriage, multiple component supply units can be replaced all at once, making component supply unit setup easy, but maintenance is difficult because a carrier tape cutting device is mounted on each carriage.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-13308 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-64929 Summary of the Invention [Problem to be solved by the invention]

[0006] For the reasons described above, if one were to try to incorporate the advantages of both the former and latter types, it would be possible to install the carrier tape cutting device on the base and replace the component supply units all at once using a cart. However, in a component mounting device with such a configuration, when the cart is separated from the base, the cutter of the carrier tape cutting device is located within the reach of the operator, so it is necessary to ensure the safety of the operator.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a component mounting device and a carriage that can ensure the safety of an operator in relation to the carrier tape cutting device even when the carriage is separated from the base. [Means for solving the problem]

[0008] The component mounting device of the present invention comprises: a base; a component mounting unit having a substrate holding unit provided on the base and holding a substrate; a work head that picks up components from a carrier tape and mounts them on the substrate held by the substrate holding unit; and a carrier tape cutting device that cuts the carrier tape from which the components have been picked up; a carriage that has a feeder base unit that holds an array of component supply units that feed the carrier tape to a component pick-up position by the work head, and is detachable from the base; and disabling means that disables operation of the carrier tape cutting device when the carriage is separated from the base. The carrier tape cutting device includes an actuator that moves a cutter by energy transmitted through an energy transmission path, and the disabling means cuts off the energy transmission path when the carriage is separated from the base. .

[0009] The cart of the present invention is a cart that can be attached and detached to a component mounting section and has a base, a substrate holding section provided on the base and holding a substrate, a work head that removes components from a carrier tape and mounts them on the substrate held by the substrate holding section, and a carrier tape cutting device that performs a cutting operation with an actuator operated by energy transmitted through an energy transmission path to move a cutter and cut the carrier tape from which the components have been removed, and has a feeder base section that holds an array of multiple component supply units that feed the carrier tape to a component removal position by the work head, and a midway section of the energy transmission path, and when separated from the base, the midway section of the energy transmission path separates and the energy transmission path is severed. [Effects of the Invention]

[0010] According to the present invention, the safety of an operator in relation to the carrier tape cutting device can be ensured even when the carriage is separated from the base. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a component mounting device 1 according to one embodiment of the present invention. The component mounting device 1 is a device that performs a component mounting operation by mounting components onto a board KB carried in from an upstream device and carrying the board out to a downstream device.

[0013] 1 and 2, component mounting device 1 includes a component mounting section 1A that transports substrate KB horizontally and mounts components on substrate KB, and a component supply section 1B that supplies components to component mounting section 1A. For ease of explanation, the transport direction of substrate KB in component mounting device 1 is referred to as the X direction (horizontal direction), and the up-down direction (perpendicular to the paper surface) is referred to as the Z direction. The direction perpendicular to both the X direction and the Z direction is referred to as the Y direction (front-to-back direction), and the side of the Y direction facing the center of base 11 (the side toward substrate holding section 12) is referred to as the rear, and the side facing the opposite (the side toward the end of base 11) is referred to as the front.

[0014] 1 and 2, the component mounting section 1A includes a base 11, a substrate holding section 12, a work head moving mechanism 13, a work head 14, a component camera 15, and a carrier tape cutting device 16. In Fig. 3, the component supply section 1B includes a carriage 21 and a plurality of component supply units 22 attached to the carriage 21. Each component supply unit 22 is made up of a tape feeder, and performs a feeding operation of the carrier tape CT to supply components to a predetermined component pick-up position 22K.

[0015] 1 and 2, the substrate holder 12 consists of two conveyors 12a arranged parallel to one another in a horizontal plane, which transport the substrate KB received from the upstream device in the X direction and hold the substrate KB at a predetermined working position. The working head moving mechanism 13 consists of a Y drive motor 13a extending in the Y direction and two beams 13b extending in the X direction. Each beam 13b is equipped with an X drive motor, which moves the working head 14 in the X direction.

[0016] 2, the work head 14 is equipped with a plurality of nozzles 14N extending downward. The work head 14 picks up components supplied to the component pick-up position 22K by the component supply unit 22 using the nozzles 14N, carries the components above the board KB, and mounts them in the specified position.

[0017] 1 and 2, component camera 15 is mounted on base 11, with its imaging field of view facing upward. When work head 14 moves above board KB with a component picked up by nozzle 14N, component camera 15 captures an image of the component from below to recognize the component.

[0018] 2, the carrier tape cutting device 16 is provided at a position opposite the component supply unit 1B of the base 11. The carrier tape cutting device 16 cuts the carrier tape CT discharged by each component supply unit 22 (the carrier tape CT after the work head 14 has taken out the components) into strips.

[0019] In the component mounting device 1 configured as described above, this embodiment is characterized by a configuration including a carrier tape cutting device 16 provided on the base 11 of the component supply unit 1B and the component mounting unit 1A, which will be explained below.

[0020] 1 and 2, a pair of left and right protrusions 11H is provided at each end of the base 11 in the Y direction. The left and right protrusions 11H protrude outward in the Y direction and face each other with a gap in the X direction. A rear wall 11W of the base 11 extending along the XZ plane is provided at the base of the left and right protrusions 11H, and a front wall 11J (see FIG. 9) extending along the XZ plane is disposed in front of the rear wall 11W so as to face the rear wall 11W in the Y direction. The space surrounded by the left and right protrusions 11H and the rear wall 11W of the base 11 forms a cart mounting station 11S where a cart 21 of the component supply unit 1B is mounted.

[0021] The component supply unit 1B is mounted on a carriage mounting station 11S at each end of the base 11 in the Y direction (FIGS. 1 and 2). As shown in FIGS. 2 and 3, the carriage 21 has a carriage base 31 and a feeder base 32. The carriage base 31 is provided with a plurality of casters 31C on its bottom, allowing it to be moved on the floor. An operator can manually move the carriage 21 to attach or detach the carriage 21 to or from the base 11. A box-shaped tape waste receiver 31T is provided on the bottom of the carriage base 31. Strips of carrier tape CT (cuttings) cut by the carrier tape cutting device 16 drop into the tape waste receiver 31T and are collected and recovered.

[0022] 2, a pair of left and right carriage guides 11G are provided on the lower parts of the inner surfaces (two surfaces facing each other in the X direction) of the left and right protrusions 11H. Each of the left and right carriage guides 11G is equipped with a plurality of guide rollers 11R. When the carriage 21 is mounted (inserted) into the carriage mounting station 11S, the carriage guides 11G guide the carriage 21 approaching the base 11 using the plurality of guide rollers 11R. This allows the carriage 21 to be smoothly guided into the carriage mounting station 11S.

[0023] As described above, the base 11 provided in the component mounting section 1A has a pair of left and right protrusions 11H that protrude toward the carriage 21 (forward), and these left and right protrusions 11H are provided with carriage guide sections 11G that guide the carriage 21 approaching the base 11.

[0024] 3, a guide post 33 is provided on the top of the carriage base 31, extending in the Z direction. A bottom 34 of the feeder base section 32 is provided at the upper end of the guide post 33. The bottom 34 of the feeder base section 32 is made of a flat plate-like member that extends along the XY plane. A support section 35 is provided on the top surface of the bottom 34, extending upward, and a unit mounting section 36 is attached to the upper end of the support section 35.

[0025] A plurality of component supply units 22 are mounted in the unit mounting section 36 in a line in the X direction (FIG. 1). The guide posts 33 are slidable in the vertical direction, allowing the feeder base section 32 to move up and down relative to the carriage base 31. A tape discharge guide 37 is provided at the rear of the unit mounting section 36 and extends downward (FIG. 3).

[0026] In Figure 3, a reel RL is held on the carriage base 31. A carrier tape CT is wound around the reel RL. Each of the multiple component supply units 22 attached to the feeder base section 32 supplies components to the component pick-up position 22K by pulling out the carrier tape CT from the corresponding reel RL and sending the leading end of the carrier tape CT rearward (toward the component mounting section 1A). After the carrier tape CT supplies the components to the component pick-up position 22K (i.e., after the components are picked up by the work head 14), it is discharged from the rear of the component supply unit 22 and guided downward by the tape discharge guide 37.

[0027] As described above, in this embodiment, the feeder base portion 32 is provided with the tape discharge guide 37 that guides the carrier tape CT discharged from the component supply unit 22 downward.

[0028] 2, a carriage mounting section 38 is provided in the carriage mounting station 11S of the base 11. As also shown in Fig. 4, the carriage mounting section 38 is configured to include a moving section 39 and a moving section drive mechanism 40. The moving section 39 is provided in front of the rear wall 11W of the base 11 in a state where it is allowed to move up and down relative to the base 11. The moving section drive mechanism 40 is installed behind the rear wall 11W, i.e., inside the base 11. A carrier tape cutting device 16 is provided in the moving section 39.

[0029] 5, 6, and 7 (FIG. 7 is a cross-sectional view taken along line AA in FIG. 5), the moving section 39 includes a pair of left and right front plates 41, a back plate 42, a pair of left and right side plates 43, and a bottom plate 44. The left and right front plates 41 are each made of a plate-like member extending along the XZ plane and are arranged side by side in the X direction at a predetermined interval. The back plate 42 is made of a plate-like member extending along the XZ plane and is located behind the left and right front plates 41.

[0030] 5, 6, and 7, the left and right side plates 43 are each made of a plate-like member extending along the YZ plane. The left and right side plates 43 are joined to the widthwise (X-direction) ends of the left and right front plates 41 and the widthwise end of the back plate 42. The front ends of the left and right side plates 43 are located forward of the front plate 41.

[0031] The bottom plate 44 is made of a plate-like member extending along the XY plane. The front end of the bottom plate 44 is joined to the lower parts of the left and right front plates 41, and the left and right ends of the bottom plate 44 are joined to the left and right side plates 43. The bottom plate 44 is provided with stopper insertion holes 44H that penetrate in the thickness direction (Z direction).

[0032] The carrier tape cutting device 16 will now be described. As shown in Figures 5, 6 and 7, the carrier tape cutting device 16 is provided in a space surrounded by left and right front plates 41, a back plate 42, left and right side plates 43 and a bottom plate 44 of the moving section 39.

[0033] The carrier tape cutting device 16 includes a cutter 50 consisting of a fixed blade 51 and a movable blade 52, and a cutter drive cylinder 53 that drives the cutter 50 (more specifically, the movable blade 52). As shown in Figures 5 and 6, the fixed blade 51 and the movable blade 52 each have a shape that extends horizontally in the X direction. The edge of the fixed blade 51 (fixed blade edge 51E) faces forward, and the edge of the movable blade 52 (movable blade edge 52E) faces backward.

[0034] 7, a pair of left and right rails 54 that protrude upward and extend in the Y direction are provided on the upper surface of the bottom plate 44. A slider 55 is engaged with the upper edge of each rail 54 and is slidable in the Y direction along the rails 54. A plate-shaped moving blade mounting portion 56 that extends horizontally in the X direction is attached to the upper surface of the left and right sliders 55.

[0035] 5 and 6, one cutter drive cylinder 53 is provided on each of the left and right front plates 41. The left and right cutter drive cylinders 53 are air cylinders, and each has an output shaft 53J facing rearward (FIG. 7). The output shaft 53J of each cutter drive cylinder 53 passes rearward through the front plate 41, and its tip is connected to the underside of the moving blade mounting part 56 via a block-shaped connecting part 57 (FIGS. 5 and 6).

[0036] 7, the fixed blade 51 is attached to the upper end of the back plate 42. The movable blade 52 is attached to the upper surface of the movable blade mounting part 56 and is supported by the left and right rails 54 via the movable blade mounting part 56 and the slider 55 so as to be movable in the Y direction. As described above, the movable blade mounting part 56 is connected to the output shafts 53J of the left and right cutter drive cylinders 53 via the left and right coupling parts 57, so that the movable blade 52 can be moved in the Y direction by the left and right cutter drive cylinders 53.

[0037] When the left and right cutter drive cylinders 53 advance the output shaft 53J, the movable blade 52 moves in a direction approaching the fixed blade 51 (rearward) (Fig. 8(a) → Fig. 8(b)). When the left and right cutter drive cylinders 53 retreat the output shaft 53J, the movable blade 52 moves in a direction away from the fixed blade 51 (forward) (Fig. 8(b) → Fig. 8(a)).

[0038] 7, a flat plate-shaped fixed safety cover 58 extending in the X direction in a horizontal position is provided in front of the fixed blade 51. The fixed safety cover 58 is provided in a position that covers part of the movement range of the moving blade 52 in the Y direction from above.

[0039] 7, the lower end of the tape discharge guide 37 of the feeder base 32 is located above the space sandwiched between the fixed blade 51 and the fixed safety cover 58. Therefore, the space between the fixed blade 51 and the fixed safety cover 58 is a space through which the carrier tape CT discharged from the component supply unit 22 moves from top to bottom. This space functions as an inlet for the carrier tape CT to the cutter 50, and will be referred to as the "carrier tape inlet 59" hereinafter.

[0040] 7 and 8(a) and (b), the fixed blade 51 has its edge (fixed blade edge 51E) positioned within the carrier tape inlet 59. That is, the fixed blade 51 is in a state of being ejected horizontally relative to the space (carrier tape inlet 59) through which the carrier tape CT moves from top to bottom. On the other hand, when the moving blade 52 moves rearward and approaches the fixed blade 51, its edge (moving blade edge 52E) is positioned within the carrier tape inlet 59 (FIG. 8(b)).

[0041] 5 and 8(a) show a state in which the cutter drive cylinder 53 operates the output shaft 53J to move the moving blade 52 to the maximum extent. Hereinafter, this position of the moving blade 52 will be referred to as the "most retracted position." When the moving blade 52 is in the most retracted position, the moving blade edge 52E is located below the fixed safety cover 58.

[0042] 6 and 8(b) show a state in which the cutter drive cylinder 53 operates the output shaft 53J to move the moving blade 52 forward to its fullest extent. Hereinafter, this position of the moving blade 52 will be referred to as the "most forward position." When the moving blade 52 is in its most forward position, the moving blade edge 52E advances to a position below the fixed blade 51.

[0043] 7, a plate-shaped chip guide 61 that extends along the XZ plane as a whole is provided on the rear side of the bottom plate 44. The space between the chip guide 61 and the back plate 42 forms a chip passage 62 that extends in the Z direction, and a discharge port 63 is provided at the bottom of the chip passage 62. As shown in FIGS. 9 and 10, a discharge duct 11D that is fixed to the rear wall 11W and the front wall 11J is provided below the discharge port 63. The chips discharged from the discharge port 63 are sent to the tape waste receiver 31T via the discharge duct 11D.

[0044] When the movable blade 52 moves from the most retracted position to the most advanced position, the movable blade edge 52E crosses the cutting position 50P (FIGS. 7 and 8(a)) located between the carrier tape inlet 59 and the outlet 63 (more specifically, on the fixed blade edge 51E). If an object to be cut is present at the cutting position 50P at this time, the movable blade cuts the object by the relative movement of the movable blade edge 52E and the fixed blade edge 51E.

[0045] The operation of the cutter 50 to cut the object to be cut by the operation of the moving blade 52 will be referred to as the "cutting operation" hereinafter. In this embodiment, the "object to be cut" refers to the carrier tape CT introduced from the component supply unit 22 through the tape discharge guide 37 into the carrier tape inlet 59 (i.e., after the components have been removed).

[0046] After the cutter 50 performs a cutting operation and the moving blade 52 is positioned at the most forward position, the left and right cutter drive cylinders 53 move the output shafts 53J backward to return the moving blade 52 to the most rearward position (Fig. 6 → Fig. 5 and Fig. 8(b) → Fig. 8(a)). Note that the cutter drive cylinders 53 always position the moving blade 52 at the most rearward position when the carriage 21 is separated from the base 11.

[0047] As described above, in this embodiment, the carrier tape cutting device 16 (cutter 50) is provided near the carrier tape inlet 59. The cutter 50 (movable blade 52) is moved by the left and right cutter drive cylinders 53 serving as cutter drive units, so that the carrier tape CT introduced from the carrier tape inlet 59 is cut at a cutting position 50P between the carrier tape inlet 59 and the discharge outlet 63.

[0048] 7 and 8(a) and (b), the tape discharge guide 37 of the feeder base 32 is located directly above the carrier tape inlet 59, so the carrier tape CT discharged from the component supply unit 22 is smoothly guided to the cutting position 50P. Also, as described above, the cutter 50 of the carrier tape cutting device 16 is provided near the carrier tape inlet 59, so the length by which the leading end of the carrier tape CT cut by the cutter 50 protrudes below the feeder base 32 can be shortened. Therefore, the leading end of the carrier tape CT does not get in the way when the cart 21 is transported or when it is mounted on another component mounting device 1.

[0049] The carrier tape CT (chips of the carrier tape CT) cut into strips by the cutter 50 falls through the chip passage 62 and is discharged from the discharge outlet 63 through the discharge duct 11D to the tape chip receiver 31T. In this way, the component mounting device 1 of this embodiment is configured to include the discharge outlet 63 and the discharge duct 11D for discharging the cut carrier tape CT.

[0050] 7, a carriage stopper 64 is provided at the rear of each of the left and right side plates 43 (see also FIGS. 5 and 6). The left and right carriage stoppers 64 each extend upward and are adapted to come into contact with the rear end 34T (FIG. 3) of the bottom 34 of the feeder base 32 of the carriage 21 when the carriage 21 is inserted into the carriage mounting station 11S of the base 11, as will be described later.

[0051] 9 and 10, three guide rollers 70 are provided at three locations on the outer surface of each of the left and right side plates 43 (see also FIGS. 5 and 6). The three guide rollers 70 consist of a rear upper roller 70a, a rear lower roller 70b, and a front roller 70c. The rear upper roller 70a is located above the rear of the side plate 43, and the rear lower roller 70b is located below the rear upper roller 70a. The front roller 70c is located in front of the rear upper roller 70a.

[0052] 4, 9, and 10, a guide plate 11P is provided on the inner surface of each of the left and right protrusions 11H of the base 11. Each of the left and right guide plates 11P is made of a plate-like member extending along the YZ plane. As shown in FIGS. 11 and 12(a), (b), and (c), the guide plate 11P has a rear upper guide groove 71 provided in correspondence with the rear upper roller 70a of the moving unit 39, and a rear lower guide groove 72 provided in correspondence with the rear lower roller 70b.

[0053] In FIG. 11 , the rear-upper guide groove 71 includes a first vertical region 71a extending in the Z direction in front of a substantially rectangular rear reference piece 73 provided on the guide plate 11P, and a first horizontal region 71b extending rearward (above the rear reference piece 73) from the top of the first vertical region 71a. The rear-upper guide groove 71 guides the movement of the rear-upper roller 70a located inside it in a direction along the YZ plane. That is, the first vertical region 71a guides the rear-upper roller 70a in the up-down direction, while the first horizontal region 71b guides it horizontally (along the Y axis). A rear vertical surface KY1 of the first horizontal region 71b of the rear-upper guide groove 71 limits the movement range of the rear-upper roller 70a in the direction along the Y axis. The lower edge of the first horizontal region 71b, i.e., the upper surface KZ1 of the rear reference piece 73, guides the movement of the rear-upper roller 70a in the direction along the Y axis.

[0054] 11, the rear lower guide groove 72 has a second vertical region 72a extending in the Z direction and a second horizontal region 72b extending rearward from an upper portion of the second vertical region 72a. The rear lower guide groove 72 guides the movement of the rear lower roller 70b located inside it in a direction along the YZ plane. That is, the first vertical region 72a guides the rear lower roller 70b in the up-down direction, and the first horizontal region 72b guides it in the horizontal direction (along the Y axis).

[0055] In Figure 11, a front reference piece 74 is provided at the front end of the guide plate 11P. A vertical surface KY3 is formed above and behind the front reference piece 74 of the guide plate 11P. The front surface 74a of the front reference piece 74 guides the movement of the front roller 70c in the vertical direction, and the top surface KZ3 guides it in the horizontal direction (along the Y-axis). The vertical surface KY3 limits the movement range of the front roller 70c in the direction along the Y-axis.

[0056] The moving unit 39 can be moved from the position shown in Fig. 12(a) (referred to as the "first position") to the position shown in Fig. 12(b) (referred to as the "intermediate position"), and then to the position shown in Fig. 12(c) (referred to as the "second position"). Conversely, it can also be moved from the second position to the intermediate position and then to the first position.

[0057] When the moving part 39 is in the first position, the rear upper roller 70a abuts against the lower edge of the first vertical region 71a of the rear upper guide groove 71, and the rear lower roller 70b abuts against the lower edge of the second vertical region 72a of the rear lower guide groove 72. The front roller 70c is located in front of the front reference piece 74 (FIG. 12(a)). When the moving part 39 is in the second position, the rear upper roller 70a is located in the first horizontal region 71b of the rear upper guide groove 71 and abuts against the upper surface KZ1 of the rear reference piece 73, and the front roller 70c is abutting against the upper surface KZ3 of the front reference piece 74. The rear lower roller 70b is located in the second horizontal region 72b of the rear lower guide groove 72 (FIG. 12(c)).

[0058] When the moving part 39 moves from the first position to the second position, the moving part 39 moves upward to reach the intermediate position and then moves horizontally (rearward) to reach the second position. When the moving part 39 moves from the second position to the first position, the moving part 39 moves horizontally (forward) to reach the intermediate position and then moves downward to reach the first position.

[0059] When the moving part 39 moves between the first position and the second position as described above, the three guide rollers 70 provided on the moving part 39 are guided by left and right guide plates 11P provided on the left and right protruding parts 11H of the base 11, and by rear reference pieces 73 and front reference pieces 74 provided on each of these left and right guide plates 11P. In other words, the left and right guide plates 11P and the rear reference pieces 73 and front reference pieces 74 provided on each of these left and right guide plates 11P form moving part guide means 75 ( FIG. 11 ) when the moving part 39 moves relative to the base 11.

[0060] In this embodiment, the moving part drive mechanism 40 is provided between a pair of protruding portions 11H of the base 11, and a moving part guide means 75 is provided on the pair of protruding portions 11H to guide the moving part 39 moved by the moving part drive mechanism 40.

[0061] 5, 6, and 7, left and right protrusions 76 are provided to protrude rearward from the back plate 42 of the moving section 39. A driven roller 77 with its rotation axis in the X direction is attached to the tip of each of the left and right protrusions 76.

[0062] 9 and 10, the moving part drive mechanism 40 is composed of an L-shaped bracket 81, a swinging member 82, a lever drive cylinder 83, a lever support 84, and a drive lever 85, each on the left and right. The L-shaped bracket 81 is attached to the lower rear surface of the rear wall 11W of the base 11, and has a portion that extends horizontally toward the rear. The front end of the swinging member 82 is pivotally connected to the portion that extends horizontally toward the rear of the L-shaped bracket 81, and is capable of swinging freely along the YZ plane. The lever drive cylinder 83 is attached to the swinging member 82, and is located on the rear surface side of the rear wall 11W. The lever drive cylinder 83 is composed of an air cylinder, and its output shaft, an operating rod 83R, faces upward.

[0063] 9 and 10, the lever support part 84 is provided at a position above the L-shaped metal fitting 81 on the rear wall 11W. A drive lever 85 is pivotally connected to the tip of the lever support part 84 by a pivot shaft 84J extending in the X direction. The rear end of the drive lever 85 is pivotally connected to the upper end of the operating rod 83R of the lever drive cylinder 83 by a connecting shaft 86 extending in the X direction. Therefore, when the lever drive cylinder 83 moves the operating rod 83R back and forth, the drive lever 85 swings around the pivot shaft 84J, raising and lowering the front end.

[0064] In detail, when the lever drive cylinder 83 advances the operating rod 83R, the drive lever 85 swings around the pivot shaft 84J in the direction of lowering the front end, and when the operating rod 83R is fully advanced, the drive lever 85 assumes a position in which the front end is fully lowered (Fig. 9). When the lever drive cylinder 83 retreats the operating rod 83R, the drive lever 85 swings in the direction of raising the front end, and when the operating rod 83R is fully retreated, the drive lever 85 assumes a position in which the front end is fully raised (Fig. 10).

[0065] 9 and 10, an opening 11K penetrating in the thickness direction (Y direction) is provided in the middle of the rear wall 11W of the base 11. Therefore, the protrusion 76 and the driven roller 77 of the moving part 39 can move in the front and rear of the rear wall 11W through the opening 11K.

[0066] 9 and 10, the front end of the drive lever 85 is shaped like a fork. The front end (the fork-shaped portion) of each of the left and right drive levers 85 engages from behind with the left and right driven rollers 77 provided on the rear side of the moving part 39 (FIG. 9).

[0067] When the carriage 21 is separated from the base 11 (when the carriage 21 is not inserted into the carriage mounting station 11S), the lever drive cylinder 83 moves the operating rod 83R forward to its fullest extent (FIG. 9), and the drive lever 85 is in a position where the front end portion is lowered to its fullest extent. In this state, the moving part 39 is in the first position (FIG. 12(a)), and the moving part 39 is located in a position close to the front wall 11J from the rear (FIG. 13(a)).

[0068] When the lever drive cylinder 83 moves the operating rod 83R backward from a state in which the operating rod 83R is moved forward to its maximum extent, the drive lever 85 swings in the direction of raising the front end portion thereof. As a result, the driven roller 77 engaged with the front end portion (the fork-shaped portion) of the drive lever 85 is lifted by the drive lever 85, and the moving part 39 rises from the first position to reach the intermediate position (FIG. 12(a) → FIG. 12(b)).

[0069] As the lever drive cylinder 83 further retracts the operating rod 83R, the drive lever 85 further raises the front end portion. As a result, the moving part 39 is attracted by the drive lever 85 and moves rearward from the intermediate position (FIG. 12(b) → FIG. 12(c)), and is held in the second position when the operating rod 83R of the lever drive cylinder 83 is fully retracted (FIG. 12(c)). The moving part 39 held in the second position is located in a position close to the rear wall 11W from the front (FIGS. 10 and 13(b)).

[0070] As described above, the component mounting device 1 in this embodiment comprises a base 11 equipped with a work head 14 that mounts components supplied by the component supply units 22 onto a substrate KB, and a cart 21 that is detachably attached to the base 11 and has a feeder base section 32 that holds a plurality of component supply units 22 in an array, and the base 11 is provided with a moving section 39 that incorporates a carrier tape cutting device 16 and a moving section drive mechanism 40 that drives the moving section 39.

[0071] Here, a description will be given of the transmission path of the power air for driving the actuators in the component mounting device 1. Fig. 14 shows the transmission path of the power air in a state where the carriage 21 is attached to the base 11.

[0072] In FIG. 14, the power air transmission pipe (referred to as "first power air transmission pipe DK1") that supplies power air to the left and right cutter drive cylinders 53 consists of a first base-side pipe 91, a relay pipe 92, and a second base-side pipe 93, and the second base-side pipe 93 is connected to the power air supply unit DA via a valve device VL. The first base-side pipe 91 is a pipe provided on the base 11, and the second base-side pipe 93 is a pipe provided on the base 11, and the relay pipe 92 is a pipe provided on the carriage 21. The valve device VL is provided on the base 11, and its operation is controlled by a control unit 11CT (FIG. 2) provided within the base 11. The power air supply unit DA is installed outside the component mounting device 1.

[0073] 14, the first base-side piping 91 and relay pipe 92 of the first power air transmission piping DK1 are connected by connecting a first coupler socket 94a on the base 11 side to a first coupler plug 95a on the bogie 21 side, and the relay pipe 92 and first base-side piping 91 are connected by connecting a second coupler plug 95b on the bogie 21 side to a second coupler socket 94b on the base 11 side. In other words, the configuration of the first power air transmission piping DK1 is first base-side piping 91-coupler (first coupler socket 94a-first coupler plug 95a)-relay pipe 92-coupler (second coupler plug 95b-second coupler socket 94b)-second base-side piping 93.

[0074] In this embodiment, power air as energy is supplied to the cutter drive cylinder 53 through the first power air transmission pipe DK1 configured as described above, thereby operating the cutter 50 of the carrier tape cutting device 16. Here, the first power air transmission pipe DK1 serves as an energy transmission path that transmits energy that drives the cutter drive cylinder 53, which is an actuator provided on the base 11 side, from the base 11 side through the carriage 21 side.

[0075] In this way, in the first power air transmission pipe DK1 that supplies power air to the left and right cutter drive cylinders 53, the intermediate section TB consisting of the first coupler plug 95a, relay pipe 92, and second coupler plug 95b is provided on the side of the carriage 21 (FIG. 14). Therefore, when the carriage 21 is not attached to the base 11, the intermediate section TB is separated from the first power air transmission pipe DK1, and the first coupler plug 95a and the first coupler socket 94a, and the second coupler plug 95b and the second coupler socket 94b are not connected, respectively, and the cutter drive cylinder 53 becomes inoperable.

[0076] For this reason, in this embodiment, in order to operate the cutter drive cylinder 53, it is necessary to attach the carriage 21 to the base 11. In other words, when the carriage 21 is separated from the base 11, the cutter 50 of the carrier tape cutting device 16 will not be driven.

[0077] The above-mentioned configuration in which "when the carriage 21 is separated from the base 11, the intermediate portion TB provided on the carriage 21 side is separated from the first power air transmission pipe DK1 (cuts off the first power air transmission pipe DK1), thereby restricting the cutting operation by the carrier tape cutting device 16" functions as a disabling means that disables the operation of the carrier tape cutting device 16 when the carriage 21 is separated from the base 11. By providing the component mounting device 1 in this embodiment with such a disabling means, the safety of the worker is ensured even when the cutter 50 of the carrier tape cutting device 16 is within the reach of the worker when the carriage 21 is separated from the base 11.

[0078] 14, the power air transmission pipe (referred to as "second power air transmission pipe DK2") that supplies power air to the component supply unit 22 attached to the feeder base 32 comprises a pipe socket 101, a plurality of individual pipes 102, a manifold 103, a main pipe 104, and a third base-side pipe 105, and the third base-side pipe 105 is connected to the power air supply unit DA via a valve device VL. The pipe socket 101, the plurality of individual pipes 102, the manifold 103, and the main pipe 104 are provided on the carriage 21, and the third base-side pipe 105 is provided on the base 11. The plurality of pipe sockets 101 provided on the carriage 21 are connected to pipe plugs 22a that the component supply unit 22 has for receiving a supply of power air.

[0079] 14, the main pipe 104 and the third base-side pipe 105 of the second power air transmission pipe DK2 are connected by connecting the third coupler plug 95c on the carriage 21 side and the third coupler socket 94c on the base 11 side. In other words, the second power air transmission pipe DK2 is configured as the pipe socket 101--plurality of individual pipes 102--manifold 103--main pipe 104--coupler (third coupler plug 95c--third coupler socket 94c)--third base-side pipe 105.

[0080] In this embodiment, power air as energy is supplied to the feeder base 32 through the second power air transmission pipe DK2 configured as described above, thereby operating the component supply unit 22. Here, the second power air transmission pipe DK2 serves as an energy transmission path for transmitting energy for driving the component supply unit 22, which is a device provided on the cart 21 side.

[0081] In this embodiment, one of the couplers constituting the second power air transmission pipe DK2 (third coupler plug 95c) is provided on the carriage 21 side, and the other of the coupler (third coupler socket 94c) is provided on the base 11 side (FIG. 14). Therefore, when the carriage 21 is not attached to the base 11, the couplers are separated, and therefore, even if the component supply unit 22 is attached to the feeder base portion 32 of the carriage 21, the component supply unit 22 will not operate unless the carriage 21 is attached to the base 11.

[0082] 14, the power air transmission piping that supplies power air to the left and right lever drive cylinders 83 provided on the base 11 consists only of the fourth base-side piping 106 provided on the base 11 side. Therefore, even if the carriage 21 is not attached to the base 11, power air can be supplied to the left and right lever drive cylinders 83, and the operation of moving the moving part 39 between the first position and the second position by the left and right lever drive cylinders 83 can be performed regardless of whether the carriage 21 is attached to the base 11 or not.

[0083] 10 and 13(a) and (b), a safety stopper 11T is provided extending upward from the upper portion of the front wall 11J constituting the moving section 39. When the carriage 21 is separated from the base 11 and the moving section 39 is in the first position (FIGS. 9 and 12(a)), the safety stopper 11T is inserted through the stopper insertion hole 44H from below. As described above, when the carriage 21 is separated from the base 11, the moving blade 52 is in the most retracted position. The safety stopper 11T mechanically prevents the moving blade 52 from advancing toward the fixed blade 51 by positioning its tip immediately behind the connecting portion 57 connected to the moving blade 52 in the most retracted position (FIG. 13(a)). The position where the safety stopper 11T is inserted through the stopper insertion hole 44H from below and prevents the moving blade 52 from moving is hereinafter referred to as the "blocking position."

[0084] As described above, when the safety stopper 11T is in the blocking position, the movement of the movable blade 52 is mechanically blocked. Therefore, when the safety stopper 11T is in the blocking position, the cutter 50 will not perform a cutting operation even if there is a malfunction or control abnormality in the cutter drive cylinder 53, ensuring the safety of the operator. After the carriage 21 is attached to the base 11, when the movable unit 39 is moved from the first position to the second position by the lever drive cylinder 83 (FIG. 12(a) → FIG. 12(b) → FIG. 12(c)), the safety stopper 11T comes out of the stopper insertion hole 44H (moves below the bottom plate 44 of the movable unit 39) in the process, and the blocked state of the movable blade 52 is released (FIG. 13(b) and FIG. 10).

[0085] In this way, the configuration in which "when the carriage 21 is separated from the base 11, the safety stopper 11T is located at the blocking position, thereby blocking the movement of the moving blade 52" functions as a disabling means (referred to as a "second disabling means") that disables the operation of the carrier tape cutting device 16 when the carriage 21 is separated from the base 11, similar to the disabling means (referred to as a "first disabling means") described above. Since the component mounting device 1 in this embodiment is provided with such a second disabling means, the safety of the worker is ensured even when the cutter 50 of the carrier tape cutting device 16 is within the reach of the worker when the carriage 21 is separated from the base 11.

[0086] 7 and 13(a) and (b), a movable safety cover 111 is provided inside the chip passage 62 of the moving part 39. The movable safety cover 111 is a plate-shaped member that extends along the XZ plane as a whole, and is disposed on the front side of the back plate 42. The movable safety cover 111 changes its position relative to the fixed blade 51 between when the moving part 39 is located at a first position and when it is located at a second position.

[0087] That is, when the carriage 21 is not attached to the carriage attachment station 11S (the moving unit 39 is in the first position), the movable safety cover 111 is positioned in a position (protecting position) where its upper end is located in front of the fixed blade 51 and covers the fixed blade edge 51E (FIGS. 13(a) and 15). On the other hand, when the carriage 21 is inserted into the base 11 (the moving unit 39 is in the second position), the movable safety cover 111 retreats from the protecting position and is positioned in a position (exposing position) where the fixed blade edge 51E is exposed (FIGS. 13(b) and 16). When positioned in the exposing position, the movable safety cover 111 is oriented along the front surface of the back plate 42 below the fixed blade 51 so as not to interfere with the movement of the carrier tape CT passing through the carrier tape inlet 59 (FIG. 13(b)).

[0088] 15 and 16, a mechanism for moving the movable safety cover 111 between the protected position and the exposed position will be described. As shown in FIGS. 15 and 16, a plate-shaped guided portion 112 is provided at the bottom of the movable safety cover 111 and extends rearward. A safety cover guide groove 113 is formed in the back plate 42 of the moving portion 39, extending vertically with its lower end bent forward. Two safety cover guide pins 114 are provided in the guided portion 112, aligned vertically. These two safety cover guide pins 114 are positioned within the safety cover guide groove 113 and are movable along the safety cover guide groove 113.

[0089] 15 and 16, a guide groove 115 extending in the vertical direction is provided in the rear wall 11W of the carriage 21. A rod-shaped link rod 116 extending obliquely downward from the back plate 42 side toward the rear wall 11W side is disposed between the back plate 42 of the moving section 39 and the rear wall 11W of the base 11. The front end (upper end) of the link rod 116 is pivotally connected to the upper one of the upper and lower safety cover guide pins 114. Meanwhile, the rear end (lower end) of the link rod 116 is pivotally connected to a guide pin 117 provided in the guide groove 115 (and therefore movable in the vertical direction along the guide groove 115).

[0090] As shown in Fig. 15, when the moving part 39 is in the first position and the moving part 39 as a whole is positioned close to the front wall 11J (Fig. 9), the movable safety cover 111 is pushed up by the link rod 116, which has its lower end guide pin 117 positioned at the lower end of the guide groove 115 (Fig. 15). With the movable safety cover 111 in this position, both the upper and lower safety cover guide pins 114 are positioned in the middle portion (portion extending in the vertical direction) of the safety cover guide groove 113. Then, due to the relationship between the attachment positions of the upper and lower safety cover guide pins 114 relative to the movable safety cover 111, the upper end side of the movable safety cover 111 is tilted forward, and the movable safety cover 111 is positioned in a protective position covering the fixed blade edge 51E.

[0091] On the other hand, as shown in Fig. 16, when the moving part 39 is in the second position and the moving part 39 as a whole is close to the rear wall 11W, the back plate 42 is moved upward compared to when the moving part 39 is in the first position. At this time, the upper and lower safety cover guide pins 114 are positioned at the lower part of the safety cover guide groove 113 due to the weight of the movable safety cover 111 (Fig. 16). In this state, due to the relationship between the inclination of the lower part of the safety cover guide groove 113 from the vertical direction and the attachment positions of the upper and lower safety cover guide pins 114 relative to the movable safety cover 111, the movable safety cover 111 is positioned below the fixed blade 51 and is oriented along the front surface of the back plate 42, and is in an exposed position that exposes the fixed blade edge 51E (Fig. 16).

[0092] As described above, the component mounting device 1 in this embodiment is configured to include the moving unit 39 that is provided on the base 11 so as to be able to rise and fall freely, and the movable safety cover 111 whose position is changed by the moving unit 39. The movable safety cover 111 is displaceable between a protective position that covers one edge (fixed blade edge 51E) of the fixed blade 51 of the cutter 50, and an exposed position that does not cover the fixed blade edge 51E; when the carriage 21 is separated from the base 11, the movable safety cover 111 is positioned in the protective position, and when the moving unit 39 rises relative to the base 11, the movable safety cover 111 displaces from the protective position to the exposed position. When the carriage 21 is separated from the base 11, the edge (fixed blade edge 51E) of the cutter 50 is protected by the movable safety cover 111, ensuring the safety of the operator.

[0093] 13(a) and 13(b), horizontal support surfaces 121 are formed at the middle and front ends in the Y direction on the top surfaces of the left and right side plates 43. An engagement pin 122 is provided on each support surface 121 so as to protrude upward (see also FIGS. 5 and 6).

[0094] 5 and 6, a connection part 130 is provided between the left and right front plates 41 of the moving part 39. As shown in Figures 17(a), (b) and 18(a), (b), the connection part 130 includes a base 131, left and right rail parts 132, a floating member 133, an electric connector socket 134, the three coupler sockets 94 (first coupler socket 94a, second coupler socket 94b, third coupler socket 94c), a shutter 136, and a shutter drive roller 137.

[0095] 17(a), (b), 18(a), (b), and 19(a), (b), the base 131 is a plate-like member extending along the XY plane, and is fixed to the bottom plate 44 of the moving part 39. The left and right rail parts 132 are disposed on the left and right sides of the base 131, and each extends in the Y direction.

[0096] 17(a) and (b), 18(a) and (b), and 19(a) and (b), floating member 133 is made of a plate-like member that extends along the XY plane. Four support columns 138 that are erected on base 131 penetrate the four corners of floating member 133 in the thickness direction. Spring members 139 are inserted into each of the four support columns 138, and these four spring members 139 support the four corners of floating member 133 from below. In this way, floating member 133 is elastically supported by the four spring members 139, and is in a so-called floating state.

[0097] 17(a) and (b)) and FIG. 18(b), the three coupler sockets 94 (first coupler socket 94a, second coupler socket 94b, third coupler socket 94c) on the moving section 39 side (base 11 side) are attached to the floating member 133 with their openings facing upward. The three coupler sockets 94 are lined up in the X direction in the order of first coupler socket 94a, third coupler socket 94c, and second coupler socket 94b. The first base-side piping 91 is connected to the first coupler socket 94a, and the second base-side piping 93 is connected to the second coupler socket 94b. The third base-side piping 105 is connected to the third coupler socket 94c (FIGS. 19(a) and (b)).

[0098] 17(a) and 17(b) and 18(b), the electrical connector socket 134 is also attached to the floating member 133 with its opening facing upward. The electrical connector socket 134 is connected to the control unit 11CT and a power supply device (not shown) via wiring 140 (FIGS. 17(a) and 17(b)) that supplies power and transmits signals.

[0099] 18(a), (b) and 19(a), (b), positioning pin guides 141 are provided on both the left and right sides of the floating member 133. Each positioning pin guide 141 is provided with a guide hole 142 that penetrates in the Z direction.

[0100] 18(b), the shutter 136 comprises a shutter main body 136a made of a plate-like member that extends as a whole in the XY plane, and left and right leg portions 136b that extend downward from both left and right ends on the front end side of the shutter main body 136a. The left and right leg portions 136b are slidable in the Y direction on the left and right rail portions 132, and the entire shutter 136 is movable in the Y direction relative to the base 131.

[0101] The shutter 136 moves in the Y direction to switch between a shielding position (FIGS. 17(a) and 18(a)) and a retracted position (FIGS. 17(b) and 18(b)). Here, the "shielding position" is a position in which the shutter main body 136a covers the three coupler sockets 94 and the electrical connector socket 134 (and therefore the openings of these sockets) from above. The "retracted position" is a position in which the shutter retracts rearward from the shielding position to expose the three coupler sockets 94 and the electrical connector socket 134.

[0102] 18(a) and 18(b), the shutter drive roller 137 is provided on the outer surface of one of the left and right legs 136b so as to be rotatable around an axis extending in the X direction. A shutter-side pin 143 that extends outward in the X direction is provided on the other of the left and right legs 136b, and a base-side pin 144 that extends in the X direction is provided on the side surface of the base 131 (the side surface on which the shutter-side pin 143 is provided). The shutter-side pin 143 and the base-side pin 144 are positioned side by side in the Y direction, and a shutter spring 145 made of a tension spring is attached between the shutter-side pin 143 and the base-side pin 144.

[0103] When no external force is acting on the shutter drive roller 137, the shutter 136 is pulled forward by the elastic force of the shutter spring 145 and is positioned at the blocking position (FIGS. 17(a) and 18(a)). On the other hand, when the shutter drive roller 137 is pressed rearward against the elastic force of the shutter spring 145 from the state in which the shutter 136 is positioned at the blocking position, the shutter 136 moves rearward and is positioned at the retracted position (FIGS. 17(b) and 18(b)).

[0104] 17(a) and (b) and 20(a) and (b), four downward-opening engagement pin insertion holes 151 are provided on the lower surface of the bottom 34 of the feeder base portion 32. In addition to the three coupler plugs 95 (first coupler plug 95a, second coupler plug 95b, third coupler plug 95c) mentioned above, an electric connector plug 152, a shutter drive pin 153, and left and right positioning pins 154 are also provided on the lower surface of the bottom 34, each extending downward (see also FIGS. 19(a) and (b)).

[0105] 19(a) and 19(b), the three coupler plugs 95 are lined up in the X direction in the order of first coupler plug 95a, third coupler plug 95c, and second coupler plug 95b, and are positioned between the left and right positioning pins 154. The main pipe 104 is connected to the third coupler plug 95c and extends above the bottom 34. The relay pipe 92 connecting the first coupler plug 95a and the second coupler plug 95b is positioned above the bottom 34.

[0106] 20(a) and 20(b), the aforementioned multiple piping sockets 101 are provided at the front end of the unit mounting section 36, opening forward (toward the component supply unit 22). The front end of the unit mounting section 36 is also provided with a wiring socket 161 that is part of a circuit (electrical circuit) for supplying power to the component supply unit 22 and transmitting signals, opening forward. The component supply unit 22 mounted on the unit mounting section 36 is provided with a piping plug 22a for introducing power air and a wiring plug 22b for supplying electricity, each of which protrudes rearward (toward the cart 21).

[0107] 20(a) and 20(b), the aforementioned manifold 103 and a relay board 162 that constitutes part of the electrical circuit are provided within the support part 35 of the feeder base part 32. The manifold 103 is connected to three coupler plugs 95 via main pipes 104, and is connected to a pipe socket 101 via individual pipes 102. The relay board 162 is connected to an electrical connector plug 152 via a main cable 163, and is connected to a wiring socket 161 via individual wiring 164.

[0108] Next, a procedure for mounting the carriage 21 on the base 11 will be described. When mounting the carriage 21 on the base 11, first, the component supply unit 22 is attached to the carriage 21 that is separated from the base 11.

[0109] As described above, when the carriage 21 is separated from the base 11 (FIG. 21), the lever drive cylinder 83 of the moving part drive mechanism 40 is in a state in which the operating rod 83R is moved forward to its maximum extent (FIG. 9). In this state, the three coupler plugs 95, which are carriage-side couplers, and the three coupler sockets 94, which are base-side couplers, of the first power air transmission pipe DK1 and the second power air transmission pipe DK2 are separated (FIGS. 17(a) and 19(a)), and the electric connector plug 152, which is a carriage-side connector, and the electric connector socket 134, which is a base-side connector, are also separated. Therefore, the cutter drive cylinder 53 of the carrier tape cutting device 16 does not operate due to the action of the first disabling means described above, and the cutter 50 is in a state in which it cannot perform a cutting operation.

[0110] When the carriage 21 is separated from the base 11 (FIG. 21), the shutter 136 of the connection part 130 is located in the shielding position. Therefore, the three coupler sockets 94, the electrical connector socket 134, and the left and right positioning pin guides 141 (left and right guide holes 142) attached to the floating member 133 are covered by the shutter 136 (FIGS. 17(a) and 18(b)).

[0111] Furthermore, when the carriage 21 is separated from the base 11, the moving part 39 is located in the first position (FIGS. 9 and 12(a)), and the safety stopper 11T is inserted into the stopper insertion hole 44H of the moving part 39 and is located in the blocking position (FIG. 13(a)). Therefore, due to the action of the second disabling means described above, the moving blade 52 of the carrier tape cutting device 16 cannot move toward the fixed blade 51, and the cutter 50 is in a state where it cannot perform a cutting operation. Furthermore, the movable safety cover 111 is in a state where it covers the fixed blade edge 51E (FIGS. 13(a) and 15).

[0112] When attaching the component supply unit 22 to the cart 21, the worker inserts the component supply unit 22 horizontally (in the Y direction) from the rear into the unit mounting portion 36 of the feeder base 32 (FIG. 20(a) → FIG. 20(b)). As a result, the piping plug 22a on the component supply unit 22 side fits into the piping socket 101 on the feeder base 32 side from the front, and the wiring plug 22b on the component supply unit 22 side fits into the wiring socket 161 on the feeder base 32 side from the front (FIG. 20(b)).

[0113] After attaching the required number of component supply units 22 to the cart 21, the worker mounts the cart 21 on the base 11. To do this, the worker first inserts the cart 21 with the component supply units 22 attached into the cart mounting station 11S of the base 11 (Fig. 21 → Fig. 22). At this time, the cart base 31 is guided by the cart guide parts 11G (guide rollers 11R) provided on the left and right overhang parts 11H of the base 11, so that the cart base 31 smoothly enters the cart mounting station 11S.

[0114] As the carriage 21 is inserted into the carriage mounting station 11S, the rear end 34T (FIG. 17(a)) of the bottom 34 of the feeder base 32 abuts against the carriage stopper 64 of the moving section 39 from the front (FIG. 17(a) → FIG. 17(b)). When the operator senses that the bottom 34 of the feeder base 32 has abutted against the carriage stopper 64 of the moving section 39, he or she stops inserting the carriage 21.

[0115] From the time when the insertion of the carriage 21 into the base 11 begins until the rear end 34T of the bottom 34 abuts against the moving section 39, the feeder base section 32 moves horizontally (rearward) above the moving section 39. Then, during the time when the rear end 34T of the bottom 34 of the feeder base section 32 abuts against the carriage stopper 64 of the moving section 39, the shutter drive pin 153 provided on the feeder base section 32 abuts against the shutter drive roller 137 provided on the shutter 136 from the front, and presses the entire shutter 136 rearward against the elastic force of the shutter spring 145.

[0116] The shutter 136 is pressed rearward and moves from the blocking position to the retracted position (FIG. 17(a) → FIG. 17(b) and FIG. 18(a) → FIG. 18(b)). As a result, the three coupler sockets 94 (first coupler socket 94a, second coupler socket 94b, third coupler socket 94c), the electrical connector socket 134, and the left and right guide holes 142, which were previously covered by the shutter 136, are exposed upward (FIG. 18(b)).

[0117] As described above, in this embodiment, when the carriage 21 approaches the base 11, the shutter drive pin 153 serving as a drive member provided on the feeder base portion 32 of the carriage 21 moves the shutter 136 from the shielding position to the retracted position. Therefore, when the carriage 21 is separated from the base 11, one of the couplers (the three coupler sockets 94 that are the base-side couplers), one of the electrical connectors (the electrical connector socket 134), and the left and right guide holes 142 that were covered by the shutter 136 are exposed upward.

[0118] When the rear end 34T of the feeder base 32 abuts against the carriage stopper 64 of the moving unit 39, the three coupler plugs 95 on the carriage 21 are positioned above the three coupler sockets 94 that are exposed when the shutter 136 is in the retracted position. Also, the electric connector plug 152 on the carriage 21 is positioned above the electric connector socket 134 (FIGS. 17(a) and 19(a)), and the left and right positioning pins 154 on the carriage 21 are positioned above the left and right guide holes 142 (FIG. 19(a)). Furthermore, the four engagement pin insertion holes 151 on the front, rear, left and right of the bottom 34 of the feeder base 32 are positioned above the four engagement pins 122 on the front, rear, left and right of the moving unit 39 (FIG. 17(a)).

[0119] When the operator has finished inserting the carriage 21 by the bottom 34 of the feeder base 32 coming into contact with the carriage stopper 64 of the moving unit 39, he or she operates the valve device VL via the control unit 11CT by performing a predetermined operation on the operating unit (not shown). As a result, power air from the power air supply unit DA is supplied to the left and right lever drive cylinders 83 through the fourth base-side piping 106, and the left and right lever drive cylinders 83 operate to retract the operating rods 83R, respectively (FIG. 22 → FIG. 23).

[0120] As a result, the operating rod 83R of the lever drive cylinder 83 retracts, and the drive lever 85 pivots in the front-end-up direction. The driven roller 77, which is engaged with the front end of the drive lever 85, rises, and the moving unit 39 is lifted by the drive lever 85 (FIG. 22 → FIG. 23). When the operating rod 83R of the lever drive cylinder 83 retracts to its fullest extent and the drive lever 85 assumes its full front-end-up position, the moving unit 39 is held in the second position (FIG. 23 and FIG. 13(b)). When the moving unit 39 moves from the first position to the second position in this manner, the lower end of the tape discharge guide 37 of the feeder base 32 is received in the upper end of the carrier tape inlet 59 of the moving unit 39, which has been lifted by the drive lever 85 (FIG. 22 → FIG. 23).

[0121] When the moving unit 39 is positioned at the second position, it moves the rear-upper roller 70a to the upper surface KZ1 of the rear reference piece 73 and moves the front roller 70c to the upper surface KZ3 of the front reference piece 74. As a result, the rear-upper roller 70a is supported from below by the upper surface KZ1, and the front roller 70c is supported from below by the upper surface KZ1. Therefore, the moving unit 39 is positioned in the Z direction relative to the guide plate 11P. Furthermore, when the moving unit 39 is positioned at the second position, it causes the rear-upper roller 70a to abut from the front against the vertical surface KY1 in the rear-upper guide groove 71. Therefore, the moving unit 39 is also positioned in the Y direction relative to the guide plate 11P. In this embodiment, the upper surfaces KZ1 and KZ3 serve as Z-direction reference surfaces for positioning the moving unit 39 in the height direction, and the vertical surface KY1 serves as a Y-direction reference surface for positioning the moving unit 39 in the horizontal direction (along the Y axis).

[0122] Before being lifted by the drive lever 85 and held at the second position, the moving unit 39 supports and lifts the feeder base unit 32 from below with the four support surfaces 121 in contact with the underside of the feeder base unit 32. As a result, the feeder base unit 32 is aligned in the height direction with respect to the base 11, and the carrier tape cutting device 16 is also aligned in the height direction with respect to the feeder base unit 32.

[0123] Here, as described above, when the four support surfaces 121 of the moving part 39 lifted by the drive lever 85 come into contact with the underside of the feeder base part 32, the four engagement pins 122 provided on the four support surfaces 121 engage from below with the four engagement pin insertion holes 151 provided on the underside of the feeder base part 32. Therefore, the feeder base part 32 is lifted by the moving part 39 while being aligned with the moving part 39.

[0124] That is, in this embodiment, support surface 121 provided on moving section 39 has the function of supporting feeder base section 32 from below, and engagement pin 122 provided on support surface 121 functions as an engagement section that aligns feeder base section 32 in the horizontal direction. Also, engagement pin insertion hole 151 provided in the bottom of feeder base section 32 serves as an engaged section that engages with engagement pin 122 as an engaging section. As described above, in this embodiment, moving section 39 is provided with side plate 43 as a support member having support surface 121 that supports feeder base section 32 from below and engagement pin 122 that serves as an engaging section that aligns feeder base section 32 in the horizontal direction, and engagement pin insertion hole 151 as an engaged section that engages with engagement pin 122 is provided in bottom 34 of feeder base section 32.

[0125] As described above, in the component mounting device 1 of the present embodiment, the moving unit 39 is provided in a state in which it is allowed to move up and down relative to the base 11, and the moving unit drive mechanism 40 moves the moving unit 39 upward when the carriage 21 is attached to the base 11. When the moving unit 39 moves upward, it lifts and holds the feeder base unit 32, so that the feeder base unit 32 is aligned with the base 11, and the carrier tape cutting device 16 is aligned with the feeder base unit 32. Therefore, it is possible to easily align the feeder base unit 32 with the base 11 and the carrier tape cutting device 16 with the feeder base unit 32, which are required when the carriage 21 is attached to the base 11.

[0126] Conventionally, when mounting the cart 21 on the base 11, the feeder base 32 is aligned in the height direction relative to the base 11 by lowering the lifted feeder base 32 and bringing it into contact with the upper surface of the base 11, which can cause the component supply unit 22 attached to the feeder base 32 to interfere with the work head 14. However, in this embodiment, the feeder base 32 is aligned in the height direction relative to the base 11 by lifting the feeder base 32, so this type of risk does not occur.

[0127] Furthermore, as described above, while the moving unit 39 is lifted by the drive lever 85 and positioned at the second position, the left and right positioning pins 154 protruding downward from the bottom 34 of the feeder base unit 32 are inserted from above into the left and right guide holes 142 provided in the floating member 133 of the connection unit 130. Then, the three coupler plugs 95 protruding downward from the bottom 34 of the feeder base unit 32 are fitted from above into the three coupler sockets 94 provided in the floating member 133 of the connection unit 130 (FIG. 19(a) → FIG. 19(b) and FIG. 24(a) → FIG. 24(b)).

[0128] Therefore, the intermediate portion TB of the first power air transmission pipe DK1 located on the carriage 21 side (the portion from the first coupler plug 95a to the relay pipe 92 to the second coupler plug 95b) is connected to another portion of the first power air transmission pipe DK1 (the portion on the base 11 side). This releases the restriction by the first disabling means, making it possible to transmit power air to the cutter drive cylinder 53 through the first power air transmission pipe DK1, and thus operating the carrier tape cutting device 16.

[0129] At almost the same time that the three coupler plugs 95 are mated with the three coupler sockets 94 from above, the electrical connector plug 152 provided on the bottom 34 of the feeder base 32 is mated with the electrical connector socket 134 provided on the floating member 133 of the connection portion 130 from above (FIG. 19(a) → FIG. 19(b) and FIG. 24(a) → FIG. 24(b)). This enables the supply of power and the transmission of signals from the base 11 to the component supply unit 22, thereby enabling the component supply unit 22 to operate.

[0130] As described above, in this embodiment, the carriage-side couplers (three coupler plugs 95) and base-side couplers (three coupler sockets 94) in the first power air transmission pipe DK1 and the second power air transmission pipe DK2 are connected to each other as the moving part 39 approaches the bottom 34 of the feeder base part 32. At the same time, the carriage-side connector (electrical connector plug 152) and base-side connector (electrical connector socket 134) in the electrical circuit that transmits power and signals to the component supply unit 22 are connected to each other.

[0131] As described above, floating member 133, on which coupler socket 94 and electrical connector socket 134 are mounted, is elastically supported by a plurality of spring members 139 and is in a floating state. Therefore, even if the axes of coupler plug 95 and coupler socket 94 or the axes of electrical connector plug 152 and electrical connector socket 134 are slightly misaligned, spring members 139 are compressed and floating member 133 sinks, connecting the coupler and electrical connector with appropriate pressure. Furthermore, the horizontal position of floating member 133 can be finely adjusted, ensuring a reliable connection between the coupler and electrical connector.

[0132] As described above, during the time when the moving part 39 is lifted by the drive lever 85 and positioned at the second position, the safety stopper 11T, which had been positioned at the blocking position until then, comes out of the stopper insertion hole 44H, and the second disabling means is released from restricting the movement of the moving blade 52. In addition, the movable safety cover 111 moves from the protecting position in which it covers the fixed blade edge 51E to the exposing position in which it exposes the fixed blade edge 51E, and the cutter 50 becomes usable.

[0133] Next, a description will be given of the case where the carriage 21 is separated from the base 11. To separate the carriage 21 from the base 11, the worker operates the valve device VL from the aforementioned operating unit (not shown) to actuate the left and right lever drive cylinders 83, and then pulls out the carriage 21 from the base 11 after the operating rod 83R has moved forward to its maximum extent.

[0134] The moving part 39 moves from the second position to the first position (Fig. 23 → Fig. 22) while the operating rods 83R of the left and right lever drive cylinders 83 are in the fully advanced state, and during this time the four support surfaces 121 of the moving part 39 move downward away from the underside of the feeder base part 32, and the feeder base part 32 is released from the state where it was lifted by the moving part 39. Furthermore, while the moving part 39 moves from the second position to the first position, the carriage-side coupler and the base-side coupler are separated (Fig. 19(b) → Fig. 19(a) and Fig. 20(b) → Fig. 20(a)), so the cutter drive cylinder 53 becomes inoperable (first disabling means). Furthermore, since the moving part 39 of the safety stopper 11T is inserted into the stopper insertion hole 44H and positioned in the blocking position (Figure 13(b) → Figure 13(a)), the cutter 50 is in a state where the moving blade 52 is prevented from moving toward the fixed blade 51 (second disabling means).

[0135] In this way, in the component mounting device 1 of this embodiment, when the carriage 21 is separated from the base 11, the disabling means (first disabling means, second disabling means) disables the carrier tape cutting device 16 (cutter 50) from cutting the carrier tape CT, so that the safety of the worker can be ensured even when the cutter 50 of the carrier tape cutting device 16 is located within the worker's reach when the carriage 21 is separated from the base 11.

[0136] Furthermore, in the process of moving part 39 moving from the second position to the first position, movable safety cover 111 is displaced from the exposed position to the protected position (FIG. 13(a) → FIG. 13(a)), and fixed blade edge 51E is protected by movable safety cover 111. Thus, in the component mounting device 1 of this embodiment, when carriage 21 is separated from base 11, movable safety cover 111 covers and protects the edge (fixed blade edge 51E) of cutter 50 of carrier tape cutting device 16, so that the safety of the worker can be ensured even when cutter 50 of carrier tape cutting device 16 is located within the reach of the worker when carriage 21 is separated from base 11.

[0137] When the operating rod 83R of the lever drive cylinder 83 is moved forward to its maximum extent, the moving part 39 is located at the first position, and the carriage 21 is pulled out toward the front of the base 11 (Fig. 22 → Fig. 21), the shutter drive pin 153 provided on the feeder base part 32 moves forward, and the shutter 136 is returned to the blocking position by the elastic force of the shutter spring 145 (Fig. 18(b) → Fig. 18(a)). As a result, the three coupler plugs 95, the electrical connector socket 134, and the left and right guide holes 142 are covered by the shutter 136 (Figs. 17(a) and 18(b)), preventing dirt and dust from entering the openings of the three coupler sockets 94 and the electrical connector socket 134, which face upward. During the work of attaching and detaching the carriage 21 from the base 11, vibrations can cause parts to fly off the carrier tape CT and fall into the connection part 130, but even in such cases there is no risk of the parts getting caught in couplers or connectors facing upward.

[0138] As described above, in the component mounting device 1 of the present embodiment, when the carriage 21 is attached to the base 11, the base-side couplers (three coupler sockets 94) that connect with the carriage-side couplers (three coupler plugs 95) and the base-side connectors (electrical connector sockets 134) that connect with the carriage-side connectors (electrical connector plugs 152) are covered by the shutter 136 when the carriage 21 is separated from the base 11. This prevents dirt and dust from entering the openings of the base-side couplers (three coupler sockets 94) and the base-side connectors (electrical connector sockets 134), which face upward, thereby preventing various problems that may arise from the entry of dirt and dust into these openings. Furthermore, because the entry of dirt and dust into the openings is prevented, the work of removing dirt and dust that would be required if dirt or dust entered the openings is also unnecessary.

[0139] As described above, in the component mounting device 1 of this embodiment, when the carriage 21 is separated from the base 11, the disabling means (first disabling means, second disabling means) disables the carrier tape cutting device 16 (cutter 50) from cutting the carrier tape CT, so that the safety of the worker can be ensured even when the carriage 21 is separated from the base 11 and the cutter 50 of the carrier tape cutting device 16 is located within the worker's reach.

[0140] Although the embodiments of the present invention have been described above, the present invention is not limited to the above and various modifications are possible. For example, the form of the component mounting unit 1A in the above-described embodiment is an example, and the component mounting unit 1A may include a base 11, a substrate holding unit 12 provided on the base 11 and holding a substrate KB, a work head 14 that removes components from the carrier tape CT and mounts them on the substrate KB held by the substrate holding unit 12, and a carrier tape cutting device that cuts the carrier tape CT from which the components have been removed.
