Description

[Technical field]

[0001] The present invention relates to a component mounting apparatus that transports and mounts components on a board, and more particularly to a component mounting apparatus that uses a tape feeder to supply components. [Background technology]

[0002] In a component mounting device equipped with a tape feeder, static electricity may be generated when the cover tape of the component tape attached to the tape feeder is peeled off from the carrier tape. Charging of the component tape due to static electricity can induce phenomena such as component misalignment within the pocket of the carrier tape and components sticking to the cover tape, leading to incorrect pickup of components by the head.

[0003] To avoid such troubles, techniques for suppressing the charging of component tapes have been studied. For example, Patent Document 1 discloses a tape feeder that humidifies the component tape using a humidifier provided midway along the component tape transport path. Patent Document 2 discloses a component mounting device in which multiple tape feeders are covered together with a cover, and a humidifier installed inside the cover humidifies the component tape in each tape feeder. Both humidifiers are devices that eject humidified air, and suppress the charging of the component tape by making it easier for static electricity generated by peeling off the cover tape to escape into the atmosphere.

[0004] [Patent Document 1] JP 2009-231521 A [Patent Document 2] JP2010-103439 Public Relations Summary of the Invention [Problem to be solved by the invention]

[0005] The techniques disclosed in Patent Documents 1 and 2 are effective in suppressing the electrostatic charge of component tapes. However, these techniques all humidify component tapes at a specific humidification level, and Patent Documents 1 and 2 make no mention of managing the humidification level appropriate for the component tapes for the multiple tape feeders installed in the component mounting device. In other words, the allowable humidification level varies depending on the structure and function of the components, or the structure and material of the tape itself (carrier tape and cover tape) in which the components are housed. Therefore, if humidification is performed uniformly at the same humidification level, problems such as damage to the components and deformation of the tape itself may occur. Patent Documents 1 and 2 state that the humidification level in the humidifier can be adjusted, but make no mention of managing the humidification level appropriate for the component tape attached to each tape feeder.

[0006] The present invention has been made in consideration of the circumstances described above, and aims to provide a technique for humidifying a component tape in a component mounting device in which components are supplied using a component tape, while minimizing the effects on the components and the tape on which the components are stored. [Means for solving the problem]

[0007] According to one aspect of the present invention, there is provided a component mounting apparatus comprising: a component supply area in which the component supply units are arranged; and a mounting machine main body which removes components from the component supply units by a head which moves between the component supply area and a board, and mounts the components on the board, wherein the component supply units include a tape feeder which feeds out a component tape consisting of a carrier tape on which components are stored and a cover tape which is affixed to the carrier tape to cover the stored components, and which supplies components to a predetermined component removal position by peeling the cover tape from the carrier tape along the way, and a humidifier which humidifies the component tape and is capable of changing the humidification level, and the component mounting apparatus further includes a humidification control unit which controls the humidification level of the humidifier on the basis of information about the component tape attached to the tape feeder of the component supply units, and the humidification control unit controls the humidifier so that the component tape is humidified at a predetermined humidification level according to at least one of the types of components supplied by the component supply units and the type of the tape itself on which the components are stored.

[0008] In this component mounting device, components are supplied by a component supply unit. The component supply unit includes a tape feeder and a humidifying device. The tape feeder supplies components to a predetermined component removal position while moving the component tape, and the humidifying device humidifies the component tape. By humidifying the component tape in this manner, charging of the component tape is suppressed or prevented. In this case, the humidifying device is controlled by the humidification control unit to humidify the component tape at a humidification level determined according to the type of components or the type of the tape itself (carrier tape and cover tape) on which the components are stored. Therefore, this component mounting device realizes more appropriate humidification according to the type of components or the type of the tape itself on which the components are stored. In other words, the component tape can be humidified while suppressing any effects on the components or the tape itself on which the components are stored. In addition, the humidified component tape can be introduced into the tape feeder through the tape inlet while the humidifier is humidifying the component tape. Furthermore, when the humidifier is removed from the tape feeder, the component tape wound on a reel or the like can be introduced directly into the tape feeder through the tape inlet. This makes it possible to change whether or not to have a humidifier.

[0009] In the component mounting apparatus, it is preferable that the humidification control section controls the humidification device so that the component tape is humidified only while the mounting machine main body is in operation.

[0010] This configuration prevents the component tape from becoming excessively humidified while the mounting machine main body is stopped due to an error stop or the like.

[0011] In the component mounting apparatus, it is preferable that the humidification control section controls the humidifier so that humidification of the component tape is performed only in a component supply unit that is in operation among the plurality of component supply units.

[0012] With this configuration, since the component tape is humidified only for the component supply units that are actually operating, excessive humidification of the component tape is prevented for stopped component supply units. Therefore, in a production mode in which multiple component supply units used to produce multiple types of boards are arranged in a component supply area in advance, and only the component supply units corresponding to the boards (types) actually being produced are selectively operated, excessive humidification of the component tape for stopped component supply units is prevented.

[0015] In this case, it is preferable that the humidifier is fixed to the rear end portion with a magnet. With this configuration, it is possible to attach and detach the humidifier to and from the tape feeder with a simple structure and a simple operation (task).

[0016] In the above-mentioned component mounting apparatus, the humidification device may include a water-retaining member that retains water in an impregnated state, and a pressing mechanism that presses the component tape against the water-retaining member, and the humidification control unit may be configured to control the pressing operation of the component tape against the water-retaining member by the pressing mechanism so that the component tape is humidified at the determined humidification level.

[0017] In this configuration, when the component tape is pressed against the water retention member, water seeps out from the water retention member and the component tape is wetted by the water, thereby humidifying the component tape. The humidification control unit controls the pressing of the component tape against the water retention member, so that the component tape is humidified to a predetermined humidification level. This makes it possible to appropriately humidify the component tape to a predetermined humidification level.

[0018] In the above-described component mounting apparatus, the humidifier may include a water storage section for storing water for humidification, and an ultrasonic vibrator for generating mist by generating ultrasonic vibrations in the water stored in the water storage section, and the humidification control section may be configured to control the operation of the ultrasonic vibrator so that the component tape is humidified at the determined humidification level.

[0019] In this configuration, the ultrasonic transducer is operated to generate mist from the water stored in the water storage unit, and the component tape is wetted by the mist, thereby humidifying the component tape. The humidification control unit controls the operation of the ultrasonic transducer to humidify the component tape to a specified humidification level. This makes it possible to appropriately humidify the component tape to the specified humidification level.

[0020] In the above-mentioned component mounting device, it is preferable that a plurality of set grooves are provided parallel to each other in the component supply area, and the component supply unit is arranged in the component supply area with at least a portion of each of the tape feeder and the humidifier inserted into the set groove.

[0021] According to this configuration, it is possible to stably arrange the component supply unit (tape feeder and humidifier) ​​in the component supply area while positioning it properly. Another component mounting apparatus according to one aspect of the present invention is a component mounting apparatus including a plurality of component supply units, and a component supply area in which the plurality of component supply units are arranged, and a mounting machine main body that picks up components from the component supply units using a head that moves between the component supply area and a board and mounts the components on the board, wherein the component supply units include a tape feeder that feeds out a component tape consisting of a carrier tape on which components are stored and a cover tape that is attached to the carrier tape to cover the stored components, and peels the cover tape from the carrier tape along the way to supply components to a predetermined component removal position, and a component supplying device that humidifies the component tape and absorbs the humidified component tape. and a humidifying device capable of changing the humidity level, the component mounting device further including a humidifying control unit that controls the humidification level of the humidifying device based on information about the component tape attached to the tape feeder of the component supply unit, the humidifying device including a water-retaining member that retains water in an impregnated state, and a pressing mechanism that presses the component tape against the water-retaining member, the humidification control unit controlling the pressing operation of the component tape against the water-retaining member by the pressing mechanism so that the component tape is humidified at a predetermined humidification level depending on at least one of the types of components supplied by the component supply unit and the type of tape itself on which the components are stored.

[0022] On the other hand, a component supply unit according to one aspect of the present invention is a component supply unit mounted on the component mounting apparatus described above, and includes a tape feeder that feeds out a component tape consisting of a carrier tape on which components are stored and a cover tape that is attached to the carrier tape to cover the stored components, and supplies components to a predetermined component removal position by peeling the cover tape from the carrier tape along the way, and a humidifier that humidifies the component tape and is capable of changing the humidification level, and the humidifier is configured to be controllable by the humidification control unit.

[0023] This component supply unit, when mounted on the mounting machine body as described above, makes it possible to more appropriately humidify the component tape depending on the type of components stored therein and the type of tape itself.

[0024] The humidifying device according to one aspect of the present invention is a tape feeder that supplies components to a predetermined component removal position by feeding out a component tape consisting of a carrier tape on which components are stored and a cover tape that is affixed to the carrier tape to cover the stored components, and peeling the cover tape from the carrier tape along the way, and the humidifying device comprises an end portion having a tape inlet and a guide passage that guides the component tape introduced from the tape inlet to the component removal position, and together with the tape feeder, forms a component supply unit as described in claim 9. The humidifying device further comprises a connecting portion that is detachably connected to the end portion of the tape feeder, and a passage portion that communicates with the guide passage via the tape inlet when connected to the end portion, and is configured to humidify the component tape passing through the passage portion.

[0025] By connecting this humidifying device to the end of the tape feeder, it is possible to form, together with the tape feeder, the component supply unit as described above, which is capable of humidifying the component tape. Effect of the Invention

[0026] According to the present invention as described above, in a component mounting apparatus in which components are supplied using a component tape, it is possible to humidify the component tape while minimizing any effects on the components or the tape on which the components are stored.

[0028] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0029] [Overall configuration of component mounting device 1] 1 is a plan view from above showing the overall configuration of a component mounting apparatus 1 according to an embodiment of the present invention. The component mounting apparatus 1 is an apparatus for mounting components, such as electronic components, on a board P, such as a printed circuit board. The component mounting apparatus 1 includes a mounting machine main body 2 having a base 3, a conveyor 4, a component supply area 5, a head unit 6, and a component recognition camera 16, and a component supply unit 25 arranged in the component supply area 5 of the mounting machine main body 2.

[0030] The base 3 is a mounting base for various devices equipped in the component mounting apparatus 1. The conveyor 4 is a transport line for the board P, which is installed on the base 3 so as to extend in the X direction, and is composed of a pair of belt-type conveyors 4a. The conveyor 4 carries the board P in from outside the machine to a predetermined mounting work position, and after the mounting work, carries the board P out of the machine from the mounting work position. The conveyor 4 has a clamp mechanism (not shown) that holds the board P at the mounting work position. The position of the board P shown in FIG. 1 is the mounting work position.

[0031] The component supply areas 5 are provided on both sides of the conveyor 4 in the Y direction. Various devices that supply mounted components are arranged in the component supply areas 5. In this example, a plurality of component supply units 25 are arranged in parallel in each component supply area 5. The component supply units 25 will be described in detail later.

[0032] Head unit 6 picks up components in component supply area 5, moves to a mounting work position, and mounts the components on board P. Head unit 6 has multiple shaft-shaped heads 7 that adsorb and hold the components when picking, and release the held components when mounting. Heads 7 can move up and down relative to head unit 6 and rotate around their axes, and are driven by a head drive mechanism 8 (FIG. 6) that uses a motor as a drive source.

[0033] The mounting machine body 2 includes a head unit driving mechanism 10 that moves the head unit 6 in the horizontal direction (X and Y directions) at least in the space above between the component supply area 5 and the board P held at the mounting work position. The head unit driving mechanism 10 is configured with an orthogonal type robot. That is, the head unit driving mechanism 10 includes fixed rails 12 fixed to a pair of elevated frames installed on the base 3, a beam 14 that moves in the Y direction along the fixed rails 12, and a unit support part (not shown) that moves in the X direction along the beam 14. The head unit 6 is attached to this unit support part. The beam 14 and the unit support member are each moved by the driving force of a motor. The head unit 6 moves to an arbitrary position in the X and Y directions by the movement of the beam 14 and the unit support member.

[0034] The component recognition camera 16 captures images of components being transported from the component supply areas 5 to the board P by the head unit 6. Therefore, the component recognition camera 16 is disposed between each component supply area 5 on the base 3 and the mounting work position (conveyor 4). The state of the components being picked up by the head 7 is recognized based on the images captured by the component recognition camera 16, and the target position when the head unit 6 moves is corrected based on the recognition result. This improves the accuracy of the mounting position of the components on the board P.

[0035] [Configuration of component supply unit 25 (first embodiment)] 2 is a side view of the component supply unit 25 arranged in the component supply area 5. More specifically, it is a side view of the component supply unit 25 arranged in the component supply area 5 on the Y1 side of the conveyor 4. The conveyor side (the Y2 side in FIG. 2) of the component supply unit 25 is the "front" and the opposite side is the "rear".

[0036] The component supply unit 25 has a flat shape with a smaller dimension in the width direction (X direction) than in the front-rear direction (Y direction). The component supply unit 25 is disposed on a unit mounting base 20 provided in the component supply area 5. The unit mounting base 20 includes a plate-shaped base portion 21 extending in the X direction, and a unit fixing portion 22 rising upward from the conveyor side end of the base portion 21. The base portion 21 is formed with a plurality of guide rail portions 21a (corresponding to the "set groove" of the present invention) extending in the Y direction at regular intervals in the X direction. The guide rail portions 21a are positioning grooves formed on the upper surface of the base portion 21. The component supply unit 25 is supported by the unit mounting base 20 in a state where it is positioned in the X direction by the guide rail portions 21a, as described later.

[0037] The component supply unit 25 is composed of a tape feeder 26 and a humidifier 28 detachably connected to the rear end thereof.

[0038] Tape feeder 26 has the same basic configuration as known tape feeders. That is, tape feeder 26 feeds out ribbon-shaped (strip-shaped) component tape 80, while supplying (transporting) mounted components (hereinafter simply referred to as components) such as chip resistors stored on component tape 80 to a predetermined component removal position P1 by head 7. Component tape 80 is wound on a reel (not shown). The reel is disposed behind component supply unit 25 (Y1 side in FIG. 2) and below unit mounting base 20. Tape feeder 26 unwinds component tape 80 from the reel and delivers it to component removal position P1.

[0039] 5 is a perspective view showing an example of a component tape 80. The component tape 80 is composed of a carrier tape 82 on which components C are housed and a cover tape 84 attached to the carrier tape 82. The carrier tape 82 is made of synthetic resin or paper, and the cover tape 84 is made of synthetic resin.

[0040] A plurality of pockets 83a (component storage sections) that open upward are formed at regular intervals in the longitudinal direction on the carrier tape 82, and each pocket 83a stores a component C. Engagement holes 83b that penetrate in the thickness direction are formed at regular intervals in the longitudinal direction at a position near one end of the carrier tape 82 in the width direction.

[0041] The cover tape 84 is a film-like sheet that is attached to the carrier tape 82 in the longitudinal direction so as to cover the opening of the pocket 83a. By peeling the cover tape 84 from the carrier tape 82, the component C in the pocket 83a can be removed.

[0042] The tape feeder 26 has a feeder body 30 made of, for example, die-cast aluminum, which corresponds to a frame, and a clamp 31, a tape delivery mechanism 32, a tape take-up mechanism 34, a tape peeling member 36, and a cover tape recovery section 38 provided on the feeder body 30.

[0043] The feeder body 30 has a body front part 30a supported by the unit fixing part 22 of the unit mounting base 20, and a body rear part 30b supported by the base part 21. A convex part 301 extending in the front-rear direction is formed on the underside of the body rear part 30b, and a clamp 31 is provided on the front end part of the body rear part 30b. The convex part 301 is inserted into the guide rail part 21a of the base part 21, and the clamp 31 is engaged with the unit fixing part 22. With this configuration, the tape feeder 26 is fixed to the unit mounting base 20 while being positioned in the X direction.

[0044] Feeder body 30 is formed with tape passage 302 (see FIG. 3) that extends in the front-rear direction. Tape passage 302 (corresponding to the "guide passage" of the present invention) extends from the lower rear end of feeder body 30 to the upper front end. Component tape 80 is introduced into tape passage 302 from tape inlet 303 provided on rear surface 30c (terminal end) of feeder body 30, and guided along tape passage 302 to the upper front end of feeder body 30. The component tape 80 is then guided between tape peeling member 36 provided on the upper front side of feeder body 30 and the upper surface of feeder body 30.

[0045] The tape peeling member 36 is a member for peeling the cover tape 84 from the component tape 80. A slit (not shown) that extends in the width direction (X direction) of the feeder body 30 is formed in the tape peeling member 36. Of the component tape 80, the cover tape 84 is folded back at the edge of the slit and taken up by the tape take-up mechanism 34, which will be described later. As a result of this taking up, the cover tape 84 is peeled off the carrier tape 82, and the pocket 83a is opened upward at the component removal position P1 located in front of the slit. This makes it possible for the head 7 to remove the component.

[0046] The tape feed mechanism 32 is a mechanism that feeds out the component tape 80 along the tape inlet 303 while pulling it out from the reel. The tape feed mechanism 32 is disposed in the main body front part 30a of the feeder main body 30. The tape feed mechanism 32 includes a feed motor 322, a sprocket 321, and a gear train 323 that transmits the rotational driving force of the feed motor 322 to the sprocket 321. The teeth of the sprocket 321 engage with the engagement hole 83b of the component tape 80, and as the sprocket 321 is driven to rotate, the component tape 80 is pulled out from the reel and fed out to the component removal position P1.

[0047] The tape take-off mechanism 34 is a mechanism for peeling off the cover tape 84 from the carrier tape 82 (component tape 80). The tape take-off mechanism 34 is disposed above the main body rear part 30b of the feeder main body 30. The tape take-off mechanism 34 includes a take-off motor 343, a take-off roller 341, a pinch roller 342, and a gear train 344 that transmits the rotational driving force of the take-off motor 343 to the take-off roller 341.

[0048] The take-up roller 341 and the pinch roller 342 are gears that mesh with each other. The cover tape 84 that has been peeled off from the carrier tape 82 by the tape peeling member 36 and folded back is caught between the take-up roller 341 and the pinch roller 342, and the cover tape 84 is taken up by the take-up roller 341 being driven to rotate. At this time, the tape feeding operation by the tape delivery mechanism 32 and the tape take-up operation by the tape take-up mechanism 34 are performed synchronously.

[0049] A cover tape recovery section 38 is formed behind the tape take-up mechanism 34 in the feeder body 30. The cover tape recovery section 38 is a space portion formed in the feeder body 30. The cover tape 84 taken up by the tape take-up mechanism 34 is stored in this cover tape recovery section 38.

[0050] 2, reference numeral 40 denotes a driver board for controlling the driving of tape feeder 26, and more specifically, controls the driving of delivery motor 322 and take-up motor 343. Reference numeral 42 denotes a driver board for controlling the driving of humidifier 28, which will be described later, and more specifically, controls the driving of take-up motor 606, which will be described later.

[0051] The driver boards 40, 42 are arranged along the lower side of the feeder body 30. The driver boards 40, 42 are communicatively connected to a controller 70 (described later) mounted on the mounting machine body 2. Specifically, a connector 44 is provided on the front surface of the main body rear part 30b of the feeder body 30, while a connector 45 is provided on the rear surface of the unit fixing part 22 of the unit mounting base 20, and the driver boards 40, 42 and the controller 70 are electrically connected by fitting these connectors 44, 45 together.

[0052] 3 and 4 are cross-sectional views mainly showing the humidifier 28 of the component supply unit 25. The humidifier 28 is a device for humidifying the component tape 80 that has been pulled out from the reel before it is introduced into the tape feeder 26. As described above, static electricity is likely to be generated when the cover tape 84 is peeled off from the carrier tape 82, so by using the humidifier 28 to humidify the component tape 80, charging of the component tape 80 is suppressed or prevented.

[0053] The humidifier 28 has a box-shaped device body 50 made of, for example, synthetic resin, and a pressing mechanism 60 incorporated into the device body 50. The device body 50 has a flat rectangular parallelepiped shape with a smaller dimension in the width direction (X direction) than in the front-rear direction (Y direction) and is slightly elongated in the up-down direction. The width direction dimension of the device body 50 is equal to the width direction dimension of the tape feeder 26.

[0054] A magnet 66 (connecting portion) is provided on the front surface of the device main body 50. This magnet 66 and a magnet 68 fixed to the rear surface 30c of the tape feeder 26 (feeder main body 30) are attracted to each other and fixed by magnetic force. This allows the humidifier 28 to be detachably connected to the tape feeder 26. The magnets 66 and 68 have a magnetic force sufficient to allow the component supply unit 25 to be attached to and detached from the unit mounting base 20 while maintaining the connection between the tape feeder 26 and the humidifier 28.

[0055] A protrusion 501 extending in the front-rear direction is formed on the bottom surface of the device body 50. This protrusion 501, like the protrusion 301 of the tape feeder 26, is inserted into the guide rail portion 21a of the unit mounting base 20. As a result, the humidifier 28 is stably supported by the unit mounting base 20 in a state where it is positioned in the X direction together with the tape feeder 26, in other words, where it is aligned in a line in the front-rear direction with respect to the tape feeder 26.

[0056] The inside of the device body 50 is divided into an upper water storage chamber 54a and a lower machine chamber 54b by a substantially horizontal partition wall 52. The upper water storage chamber 54a is a space in which water (Wa) for humidification is stored. An opening 52a is formed in the partition wall 52 so as to penetrate in the vertical direction, and a water retention member 56 is fixed to close the opening 52a.

[0057] The water retention member 56 is made of, for example, a flexible porous material, and has the function of retaining the water in the water storage chamber 54a in a wet state, and when a pressure of a predetermined value or more is applied, the water seeps out in accordance with the pressure. The water retention member 56 is made of, for example, urethane foam (polyurethane foam resin), and at least its bottom surface is horizontal and flat, and has a rectangular shape that is elongated in the front-to-rear direction in a plan view.

[0058] A tape inlet 50a is formed on the rear surface of the device body 50, below the partition wall 52. A tape outlet 50b is formed on the front surface of the device body 50, at a position opposite the tape inlet 50a. The component tape 80 pulled out from the reel passes through the machine chamber 54b of the device body 50 via the tape inlet 50a and tape outlet 50b, and is introduced from the tape inlet 303 into the tape passage 302 of the tape feeder 26.

[0059] A pressing mechanism 60 is disposed in the machine chamber 54b. The pressing mechanism 60 is a mechanism for pressing the component tape 80 passing through the machine chamber 54b from below against the water retention member 56 by means of a pressing plate 601. When the component tape 80 is pressed against the water retention member 56, water seeps out from the water retention member 56 and wets the component tape 80. This humidifies the component tape 80. The machine chamber 54b is in communication with the tape passage 302 of the tape feeder 26 via the tape inlet 50a and the tape inlet 303, and thus corresponds to the "passage" of the present invention.

[0060] Specifically, the pressing mechanism 60 includes the pressing plate 601, a coil spring 602 supporting the pressing plate 601, a reel 605, a wire 603 wound around the reel 605 and one end of which is connected to the pressing plate 601, a winding motor 606 that drives the reel 605 to rotate and can switch the direction of rotation, and a driven roller 604.

[0061] The pressing plate 601 is, for example, a resin plate that is rectangular in plan view and extends in the front-rear direction along the underside of the water retention member 56. The coil spring 602 is provided so as to be elastically expandable and contractible in the up-down direction, and supports the center of the underside of the pressing plate 601. The wire 603 is pulled out from a reel 605, introduced from the lower end of the coil spring 602 to the center thereof via a driven roller 604, and connected to the center of the underside of the pressing plate 601 by passing through the inside of the coil spring 602.

[0062] In other words, when the reel 605 is rotated by the wind-up motor 606 in the direction in which the wire 603 is fed out, the pressure plate 601 rises due to the spring force of the coil spring 602. As the pressure plate 601 rises, the component tape 80 is pressed against the water retention member 56. Conversely, when the reel 605 is rotated in the direction in which the wire 603 is wound up, the pressure plate 601 descends against the spring force of the coil spring 602. As the pressure plate 601 descends, the component tape 80 is pulled away from the water retention member 56.

[0063] The humidifier 28 humidifies the component tape 80 by pressing the component tape 802 against the water retention member 56 through the operation of the pressing mechanism 60 as described above. A connector 64 is provided on the rear surface 30c of the tape feeder 26 (feeder body 30), and a connector 62 is provided on the front surface of the humidifier 28 (device body 50) that fits into the connector 64 when the humidifier 28 is connected to the tape feeder 26. The take-up motor 606 and driver board 42 are electrically connected by the engagement of these connectors 62, 64.

[0064] [Control system of component mounting device 1] 6 is a block diagram showing a control system of the component mounting apparatus 1. As shown in the figure, the component mounting apparatus 1 includes a controller 70. The controller 70 is configured based on a known microcomputer, and includes a CPU (Central Processing Unit) that executes various programs, and memories such as ROM and RAM for storing the programs and various data. The controller 70 includes, as its functional configuration, a mounting control unit 71, a component supply unit control unit 72, a storage unit 73, and a communication control unit 74.

[0065] The mounting control unit 71 controls the driving of the head unit driving mechanism 10 and the head driving mechanism 8 so that a predetermined component mounting operation is performed by the head 7 based on a mounting program D1 and various data stored in the storage unit 73.

[0066] The component supply unit control section 72 includes a feeder control section 72a and a humidifier control section 72b. The feeder control section 72a mainly has a function of controlling the operation of the tape feeder 26. The feeder control section 72a outputs a control signal to the driver board 40 of the tape feeder 26 via a communication control section 74 described later. This controls the operation of the tape feeder 26 so that components are supplied to the component removal position P1 in synchronization with the component mounting operation by the head 7.

[0067] The humidifier control unit 72b (corresponding to the "humidification control unit" of this invention) has a function of controlling the operation of the humidifier 28. The humidifier control unit 72b outputs a control signal to the driver board 42 via the communications control unit 74, described later, based on humidification data D2 that is pre-stored in the memory unit 73. This controls the operation of the humidifier 28 so that the component tape 80 is humidified at a humidification level that corresponds to the type of component. The humidification data D2 defines the relationship between the components stored on the component tape 80 and the humidification level to be applied by the humidifier 28. The humidification level is the degree to which the component tape 80 is humidified. The humidification data D2 is set so that, for example, components that are resistant to moisture are humidified at a higher level than components that are not.

[0068] The communication control unit 74 controls communication with each component supply unit 25 set in the mounting machine main body 2, and also controls communication with an external data management unit 75 provided outside the component mounting device 1. The external data management unit 75 stores various data related to the component supply units 25 and the component tape 80. The various data includes unit information linking the component supply units 25 set in the component mounting device 1 with components, that is, data showing the relationship between the component supply units 25 and the components supplied by the component tape 80 attached thereto. The unit information D3 is automatically created, for example, in a preparation work before a mounting work, by an operator reading, with a reading device, an identification mark such as a two-dimensional code attached to the component supply unit 25 and an identification mark such as a two-dimensional code attached to the reel of the component tape 80 attached to the component supply unit 25, and is stored in the external data management unit 75.

[0069] [Moisturization control of component tape 80] 7 is a flowchart showing an example of humidification control of the component tape 80 by the humidifier control unit 72b. When this flowchart starts, the humidifier control unit 72b acquires unit information D3 from the external data management unit 75 via the communication control unit 74 (step S1). By acquiring this unit information D3, the humidifier control unit 72b recognizes the components supplied by each component supply unit 25. Note that data (referred to as identification data D4) indicating identification information of the component supply unit 25 to which the tape feeder 26 is attached is stored in the driver board 40 of the tape feeder 26. When the component supply unit 25 is set on the unit mounting base 20 and the driver board 40 and the controller 70 are connected so as to be able to communicate with each other, the identification data D4 is read out by the controller 70. Based on this identification data D4 and the unit information D3, the humidifier control unit 72b recognizes the component supply unit 25 actually set in the component supply area 5 and the components supplied by that component supply unit 25.

[0070] The humidifier control unit 72b then determines whether the mounting machine main body 2 is operating (step S3). If the answer is Yes, the humidifier control unit 72b executes individual humidification control, in which the humidification of the component tape 80 by the humidifier 28 is controlled individually in accordance with the components supplied by each component supply unit 25 (step S4). On the other hand, if the answer is No in step S3, the humidifier control unit 72b controls the humidifiers 28 for all component supply units 25 to be stopped. The stopped state of the humidifier 28 means that the component tape 80 is not subjected to a humidification process, and is the same as the control state of the humidifier 28 in step S21, which will be described later.

[0071] 8 is a flowchart (subroutine) showing the control of the individual humidification process in step S3. In this individual humidification process, the humidifier control section 72b executes the following process for each component supply unit 25 set in the component supply area 5.

[0072] First, the humidifier control unit 72b judges whether the component supply unit 25 is out of service (step S11). If the component supply unit 25 is, for example, an unused unit in a so-called common setup, or an unused unit among a plurality of component supply units 25 that supply the same component, the humidifier control unit 72b judges Yes in step S. The setup is an operation of setting the component supply unit 25 in the component supply area 5, and the common setup refers to a setup in a production form in which a plurality of types of component supply units 25 used for producing a plurality of types of boards (component-mounted boards) are arranged in the component supply area 5 in advance, and only the component supply units 25 corresponding to the type of boards to be actually produced are selectively operated.

[0073] If the answer is Yes in step S11, the humidifier control unit 72b controls the humidifier 28 to be in a stopped state (step S21). Specifically, as shown in FIG 9(a), the pressing mechanism 60 is controlled so that the component tape 80 is spaced a certain distance from the water retention member 56 (i.e., so that the water retention member 56 and the component tape 80 are not in contact with each other). This keeps the component tape 80 from being subjected to the humidification process.

[0074] If the component supply unit 25 is not at rest (No in step S11), the humidifier control unit 72b determines whether the humidification level of the components supplied by the component supply unit 25 is "0" (step S13). As described above, the memory unit 73 stores humidification data D2 that defines the relationship between the components and the humidification levels of the humidifiers 28. Based on the humidification data D2 and the unit information D3 acquired in the process of step S1 in FIG. 7, the humidifier control unit 72b determines the predetermined humidification level for the components supplied by the component supply unit 25, and performs the determinations in step S13 and step S15 described below based on the humidification level. In the humidification data D2 in this example, three humidification levels, "0," "1," and "2," are set for each component. "0" is a level at which the component tape 80 is not humidified, and the higher the number, the higher the degree of humidification.

[0075] If the humidification level is "0" (Yes in step S13), the humidifier control section 72b shifts the process to step S21, and controls the humidifier 28 to a stopped state (step S21).

[0076] On the other hand, if the result of step S13 is No, the humidifier control unit 72b further judges whether the humidification level is "1" (step S15). If the result of step S15 is Yes, the humidifier control unit 72b proceeds to step S19 and controls the humidifier 28 to a humidification level of "1." If the result of step S15 is No, the humidifier control unit 72b proceeds to step S17 and controls the humidifier 28 to a humidification level of "2."

[0077] Specifically, in the process of step S19, the humidifier control unit 72b controls the pressing mechanism 60 so that the upper surface of the component tape 80 is pressed against the lower surface of the water retention member 56 with a pressing force F1, as shown typically in Fig. 9(b). In the process of step S17, the humidifier control unit 72b controls the pressing mechanism 60 so that the upper surface of the component tape 80 is pressed against the lower surface of the water retention member 56 with a pressing force F2 that is stronger than the pressing force F1, as shown typically in Fig. 9(c). As shown in Figs. 9(b) and 9(c), the pressing force F1 is a pressing force that allows the component tape 80 to come into contact with the water retention member 56 without deforming the lower surface of the water retention member 56, and the pressing force F2 is a pressing force that causes the component tape 80 to slightly deform (dent) the lower surface of the water retention member 56.

[0078] In this manner, the component tape 80 is pressed against the water retention member 56, causing water to seep out from the water retention member 56, thereby wetting the component tape 80 and humidifying the component tape 80. In the case of humidification level "2", the component tape 80 is pressed against the water retention member 56 with a pressing force F2 that is stronger than the pressing force F1 in the case of humidification level "1", which relatively increases the amount of water that seeps out from the water retention member 56. As a result, the component tape 80 is more humidified than in the case of humidification level "1".

[0079] Returning to Fig. 7, when the processes of steps S4 and S7 are completed, the humidifier control unit 72b judges whether or not the production of a predetermined number of component mounting boards is completed (step S5). If the result is No, the humidifier control unit 72b shifts the process to step S3 and repeats the processes of steps S3 to S5 described above. On the other hand, if the result is Yes, the series of humidification controls based on this flowchart is terminated.

[0080] [Effects, etc.] As described above, in the component mounting apparatus 1, the component supply unit 25 supplies components. The component supply unit 25 includes the tape feeder 26 and the humidifier 28. The tape feeder 26 conveys the components to the predetermined component removal position P1 while moving the component tape 80, and the humidifier 28 pre-humidifies the component tape 80. By humidifying the component tape 80 in this manner, charging of the component tape 80 caused by peeling the cover tape 84 from the carrier tape 82 is suppressed or prevented. In this case, the humidifier control unit 72b controls the humidifier 28 to humidify the component tape 80 at a humidification level that is predetermined according to the type of the component. Therefore, the component mounting apparatus 1 realizes more appropriate humidification according to the component. In other words, it is possible to humidify the component tape 80 while suppressing the components from being affected.

[0081] In particular, in the component mounting apparatus 1, the humidifier 28 is controlled so that the component tape 80 is humidified only while the mounting machine main body 2 is in operation. This prevents the component tape 80 from being excessively humidified while the mounting machine main body 2 is stopped due to an error stop or the like.

[0082] Furthermore, in the component mounting apparatus 1, the humidifier 28 is controlled so that the component tape 80 is humidified only for those component supply units 25 that are in operation among the multiple component supply units 25 set in the component supply area 5. This prevents the component tape 80 from being excessively humidified for unused component supply units 25 in the so-called common setup as described above, or for unused units among the multiple component supply units 25 that supply the same components.

[0083] In addition, in the component supply unit 25, the tape feeder 26 and the humidifier 28 are detachably connected by magnets 66, 68. Therefore, for example, if an operator recognizes during setup that the component tape 80 cannot be humidified, it is possible to detach the humidifier 28 from the tape feeder 26 and use the tape feeder 26 alone. Also, maintenance is easy, for example, by removing only the humidifier 28 from the component supply unit 25 and refilling it with water. In this case, because the tape feeder 26 and the humidifier 28 are connected by the magnetic force of the magnets 66, 68, the humidifier 28 can be attached and detached without any burden.

[0084] In the above-described component supply unit 25, the tape feeder 26 and the humidifier 28 are detachably connected via the magnets 66, 68. However, for example, a joint structure such as a "dovetail" may be provided on the opposing surfaces of the tape feeder 26 and the humidifier 28, whereby the tape feeder 26 and the humidifier 28 may be detachably connected.

[0085] In the humidifier 28, the pressing mechanism 60 is configured to move the pressing plate 601 up and down by driving the winding motor 606, but the configuration of the pressing mechanism 60 is not limited to this. For example, the pressing plate 601 may be moved up and down using an actuator other than a motor, such as an electromagnetic solenoid.

[0086] Although the component mounting apparatus 1 humidifies the component tape 80 at a predetermined humidification level according to the type of components, the component tape 80 may also be humidified at a predetermined humidification level according to the type of the tape itself (i.e., the carrier tape 82 and the cover tape 84) in which the components are stored. Alternatively, the component tape 80 may be humidified at a predetermined humidification level taking into account both the components and the tape itself.

[0087] In addition, in the component mounting apparatus 1, the humidification level of the humidifier 28 is controlled by a controller 70 (humidifier control unit 72b) provided in the mounting machine main body 2. In other words, the "humidification control unit" of the present invention is provided in the mounting machine main body 2. However, the humidification control unit may be provided in each component supply unit 25. For example, the driver board 42 may be configured to have the function of the humidification control unit. In this case, the driver board 42 may be configured to specify the humidification level by acquiring the unit information D3 and the humidification data D2 from the controller 70, and to drive and control the humidifier 28 based on the specified humidification level.

[0088] The specific configuration of the component supply units 25 installed in the component supply area 5 is not limited to the configuration described with reference to Figures 2 to 4. For example, it is also possible to apply component supply units 25A to 25C as described below.

[0089] [Second embodiment of parts supply unit] FIG. 10 is a cross-sectional view of a component supply unit 25A according to the second embodiment, and more specifically, a cross-sectional view corresponding to FIG. 4 of the first embodiment.

[0090] In the component supply unit 25 of the first embodiment, one humidifier 28 is connected to one tape feeder 26. In contrast, the component supply unit 25A of the second embodiment has a configuration in which one common humidifier 28A is connected to a plurality of tape feeders 26. In this example, one humidifier 28A is connected to three tape feeders 26. The basic configuration of each of the three tape feeders 26 is the same as in the first embodiment, but the configuration of the humidifier 28A differs from that of the first embodiment in the following points.

[0091] As shown in Fig. 10, the device body 50 of the humidifier 28A has a width equal to the width of three tape feeders 26 lined up in succession. One or more (three in this example) protrusions 501 extending parallel to each other in the front-rear direction are formed on the bottom surface of the device body 50. These protrusions are inserted into three adjacent guide rail portions 21a of the unit mounting base 20, respectively. As a result, one humidifier 28 (device body 50) is supported on the unit mounting base 20 in a state where it faces the rear of the three tape feeders 26.

[0092] The inside of the device body 50 is divided into upper and lower compartments by a partition wall 52. The upper compartment is a water storage chamber 54a. The lower compartment is divided by a partition wall 53 into three machine chambers 54b corresponding to the three tape feeders 26, respectively. A pressing mechanism 60 is disposed in each machine chamber 54b.

[0093] A water retention member 56 is provided on the partition wall 52 so as to span and face the three machine chambers 54b. Although not shown, a tape inlet 50a and a tape outlet 50b are formed at positions corresponding to each machine chamber 54b on the rear and front surfaces of the device body 50. This allows the component tape 80 to pass through each machine chamber 54b.

[0094] The connectors 62 are provided at positions corresponding to the machine chambers 54b on the front surface of the device main body 50 (humidifier 28). These connectors 62 are fitted into the connectors 64 on the tape feeder 26 side, whereby the winding motors 606 of the pressing mechanisms 60 are electrically connected to the driver boards 42 provided on the corresponding tape feeders 26.

[0095] In other words, the humidifier 28A humidifies each component tape 80 individually by pressing the component tape 80 passing through each machine chamber 54b against the water retention member 56 by operating the pressing mechanism 60 disposed in each machine chamber 54b.

[0096] The component supply unit 25A according to the second embodiment as described above has a configuration in which the humidifier 28A is shared by the three tape feeders 26, and such a component supply unit 25A can also be placed in the component supply area 5 for use.

[0097] In this case, as described above, the humidifier 28A has a configuration in which the water storage chamber 54a is shared by the three pressing mechanisms 60. This makes it possible to increase the total amount of water stored in the water storage chamber 54a compared to a case in which a humidifier 28 is connected individually to each of the three tape feeders 26. This has the advantage that the component tape 80 can be humidified continuously for a longer period of time.

[0098] Furthermore, even if there is a difference in the humidification levels of the components in each of the three tape feeders 26, the water storage chamber 54a is common, so that the amount of stored water in only a specific humidifier 28 does not decrease drastically, as would occur if a humidifier 28 were connected individually to each of the three tape feeders 26. In other words, an increase in the number of times that water is replenished only in a specific humidifier 28 is suppressed.

[0099] [Third embodiment of parts supply unit] Fig. 11 is a cross-sectional view of a component supply unit 25B according to a third embodiment, specifically, a cross-sectional view corresponding to Fig. 3 of the first embodiment. The component supply unit 25B of the third embodiment is different in configuration from the component supply unit 25 of the first embodiment in that it includes a humidifier 28B as described below.

[0100] In humidifier 28B according to the third embodiment, the interior of device body 50 is formed as a single space, and component tape 80 passes through this space through tape inlet 50a and tape outlet 50b. The space within device body 50 communicates with tape passage 302 of tape feeder 26 via tape inlet 50a and tape inlet 303, and thus corresponds to the "passage section" of the present invention.

[0101] Within the internal space of the device body 50, a portion below the position through which the component tape 80 passes is defined as a water storage section 54c, in which humidification water (Wa) is stored. A sprayer 92 is disposed on the surface of the humidification water. The sprayer 92 is provided so as to be able to move up and down in accordance with fluctuations in the water surface. The sprayer 92 includes an ultrasonic vibrator 90 made of a piezoelectric element, and while drawing in water from the water storage section 54c, the sprayer 92 generates and releases mist (M) by ultrasonic vibrations generated by the ultrasonic vibrator 90. In other words, the humidifier 28B humidifies the component tape 80 with the mist released from the sprayer 92.

[0102] As described above, the component supply unit 25B of the third embodiment is provided with a humidifier 28 that generates mist by actuating the ultrasonic transducer 90, and therefore the driver board 42 is provided with a drive circuit for the ultrasonic transducer 90. In other words, the humidifier control section 72b controls the humidification level of the component tape 80 by controlling the drive of the ultrasonic transducer 90 (sprayer 92) via the driver board 42.

[0103] Specifically, in the processing of step 7 in the flowchart of FIG. 7 and step 21 in the flowchart of FIG. 8, the humidifier control unit 72b controls the ultrasonic transducer 90 to a stopped state. This stops the generation of mist as shown in FIG. 12(a). Also, in the processing of step S17 (humidification level "2") and step S19 (humidification level "1") in FIG. 8, the high-frequency voltage applied to the ultrasonic transducer 90 is switched to change the amount of mist generated as shown in FIG. 12(b) and (c). FIG. 12(b) shows the state of humidification level "1", and FIG. 12(c) shows the state of humidification level "2".

[0104] The component supply unit 25B according to the third embodiment has been described above, but this component supply unit 25B can also humidify the component tape 80 in the same way as the component supply unit 25 of the first embodiment. If there is a risk that mist will leak out of the humidifier 28b through the tape inlet 50a and the tape outlet 50b in the component supply unit 25b, curtain-shaped leakage prevention members may be provided at the tape inlet 50a and the tape outlet 50b.

[0105] [Fourth embodiment of parts supply unit] Fig. 13 to Fig. 15 are cross-sectional views showing a component supply unit 25C according to the fourth embodiment. Specifically, Fig. 13 is a cross-sectional view corresponding to Fig. 3 of the first embodiment. Fig. 14 is a cross-sectional view taken along line XIV-XIV in Fig. 13, and Fig. 15 is a cross-sectional view taken along line XV-XV in Fig. 13. Note that the magnet 66 and the connector 62 are omitted from Fig. 13.

[0106] The component supply unit 25C of the fourth embodiment includes a humidifier 28C that generates mist to humidify the component tape 80, and is basically similar in configuration to the component supply unit 25B of the third embodiment. However, the specific configuration of the humidifier 28C in the fourth embodiment differs from that in the third embodiment as follows.

[0107] 13 to 15, in the humidifier 28C of the fourth embodiment, a tape passage 51 is formed inside the device body 50, which is a space with a rectangular cross section and bounded by an inner wall 502 on the X2 side of the device body 50 and a partition wall 57. The tape passage 51 is formed across the front-to-rear direction of the device body 50, and the component tape 80 passes through this tape passage 51 via the tape inlet 50a and the tape outlet 50b. The tape passage 51 communicates with the tape passage 302 of the tape feeder 26 via the tape inlet 50a and the tape inlet 303, and thus corresponds to the "passage section" of the present invention.

[0108] Within the device body 50, the area other than the tape passage 51 is a water storage section 54c, in which water (Wa) for humidification is stored. As shown in Fig. 14, a gap G is formed between the partition wall 57 that defines the tape passage 51 and the inner side wall 503 on the X1 side of the device body 50. As a result, the upper and lower parts of the tape passage 51 within the water storage section 54c communicate with each other.

[0109] The underside of the tape passage 51 is formed one step lower in a portion of the tape passage 51 forward of the intermediate portion in the front-rear direction than in a portion of the tape passage 51 rearward, thereby increasing the passage area. This portion with increased passage area serves as a humidification space 58 for the component tape 80.

[0110] A sprayer 92, similar to that in the third embodiment, is fixedly disposed in the water storage chamber 54a below the humidification space 58. The sprayer 92 takes in water from the water storage section 54c while operating the ultrasonic transducer 90 to generate mist, and discharges the mist from a discharge port 51a formed in the underside of the tape path 51 into the humidification space 58. In this way, the component tape 80 passing through the tape path 51 is humidified.

[0111] In the component supply unit 25C of the fourth embodiment, as in the third embodiment, the driver board 42 provided in the tape feeder 26 is provided with a drive circuit for the ultrasonic transducer 90, and the humidifier control unit 72b controls the humidification level of the component tape 80 by controlling the drive of the ultrasonic transducer 90 (sprayer 92) via the driver board 42. The control of the ultrasonic transducer 90 by the humidifier control unit 72b in accordance with the humidification level is the same as in the third embodiment.

[0112] The component supply unit 25C according to the fourth embodiment has been described above, and this component supply unit 25C can also humidify the component tape 80. In particular, with the humidifier 28C of this component supply unit 25C, as described above, most of the interior of the device body 50 is substantially the water storage section 54c. This has the advantage that it is possible to store more water, and the water replenishment cycle can be extended.

[0113] The component mounting apparatus 1 described above is an example of a preferred embodiment of the component mounting apparatus according to the present invention, and the specific configuration of the component mounting apparatus 1 and the specific configurations of the component supply units 25, 25A to 25C provided therein can be modified as appropriate without departing from the gist of the present invention.
