Description

  The present invention relates to a component mounting apparatus and a component mounting method for mounting a component supplied from a component supply unit mounted on a carriage on a substrate.

  Many component mounting apparatuses for mounting components such as ICs (Integrated Circuits) and capacitors on a substrate have been provided. In a component mounting apparatus, components supplied from a component supply unit such as a tape feeder or a tray feeder are adsorbed at the lower end of an adsorption nozzle provided in the head unit, and the head unit is held while adsorbing and holding the components with the adsorption nozzle. Move to a position above the component mounting position on the board. Thereafter, the suction nozzle is lowered toward the component mounting position, whereby the component is landed on the upper surface of the substrate and mounted on the component mounting position of the substrate.

  In the component mounting apparatus, when the type of the board is changed, a setup operation for replacing the component supply unit may be performed, and in order to cope with this, a collective exchanging cart has been frequently used. For example, when a tape feeder is used as a component supply unit, a plurality of tape feeders are mounted in a row on the batch replacement cart, and the batch swap cart is inserted into the device body of the component mounting device, so that it is mounted on the batch swap cart. The components supplied by the tape feeder thus made can be mounted on the substrate.

  In this way, a component supply space in which the tape feeder is arranged by insertion of a batch exchanging carriage and components can be supplied is provided inside the device main body, but in conventional devices, it is distinguished from the mounting space for component mounting. There wasn't. Therefore, in order to prevent unexpected interference from occurring inside the main unit during replacement of the collective exchange cart, when a protective cover or collective exchanging cart is not attached to the opening for attaching / detaching the collective exchanging cart The operation of the mounting unit such as the head unit is stopped (see, for example, Patent Document 1).

  As described above, the conventional apparatus performs nozzle preparation operations (nozzle cleaning operation, nozzle replacement operation, operation for deriving component mounting errors by nozzles, etc.) in connection with the setup work, in order to execute these nozzle preparation operations. The nozzle preparation unit was disposed between the substrate and the batch exchanging carriage, and occupied a part of the mounting space. For this reason, this has been one of the main factors that increase the size of the apparatus and reduce the degree of freedom in designing each part of the apparatus.

  This invention is made in view of the said subject, In the component mounting apparatus and method which mount the components supplied from the component supply unit with which the trolley | bogie was mounted | worn on a board | substrate, Nozzle preparation unit for performing nozzle preparation operation | movement The purpose is to reduce the occupation rate in the apparatus.

One aspect of the present invention is a component mounting apparatus for mounting a component supplied from a component supply unit mounted on a carriage on a substrate, wherein the carriage is configured to be detachable, and the component supply unit is arranged by insertion of the carriage. A device main body having a component supply space in which the component can be supplied and a mounting space for mounting the component on the board, and a nozzle capable of holding the component supplied from the component supply unit. By separating the mounting space from the component supply space in the main body of the device, the head supply unit that is transported to the substrate while holding the component , the component supply space and the mounting space can be changed during the carriage replacement by inserting and removing the carriage from the main body a cover unit to limit mutual access to enable the head unit in parallel with the carriage replacement nozzles preparation operation for performing the component mounting by the nozzle rows between Comprising a nozzle preparation unit, the nozzle preparation unit is characterized in that provided in the cover unit.

According to another aspect of the present invention, a component supply unit is arranged in a component supply space in the apparatus main body by inserting a cart on which the component supply unit is mounted into the apparatus main body, and the components supplied from the component supply unit are the component mounting method while holding the nozzle of the head unit conveys the mounting space of the apparatus main body mounted on the substrate, the mounting space and the component supply space parts supply space What partition and the mounting space by the cover unit The carriage replacement process for exchanging the carriage by inserting and removing the carriage with respect to the main body of the device while allowing the head unit to operate by restricting mutual access between them, and nozzle preparation for mounting the parts by the nozzle provided in the cover unit A nozzle preparation step for moving the head unit to the nozzle preparation unit for performing the operation and executing the nozzle preparation operation. It is characterized in.

  In the invention configured as described above, the inside of the apparatus main body is partitioned into a mounting space and a component supply space by the cover unit. And the nozzle preparation unit for performing nozzle preparation operation | movement is provided in the cover unit. For this reason, the occupation rate of a nozzle preparation unit can be reduced.

  Here, during the carriage replacement, the head unit may move to the nozzle preparation unit to perform the nozzle preparation operation, and this allows the nozzle preparation operation to be performed while the carriage replacement is performed by inserting and removing the carriage with respect to the apparatus main body. Can be executed. Therefore, the operation rate of the component mounting apparatus can be improved as compared with the conventional case.

  Further, the cover unit has a cover member having an opening that communicates the component supply space and the mounting space, a shutter member that can move forward and backward with respect to the opening, and an opening that moves the shutter member forward and backward relative to the opening. And a shutter drive unit that opens and closes the nozzle, and the nozzle preparation unit may be provided on the surface other than the opening of the cover member or on the shutter member. Thus, by controlling opening and closing of the opening by the shutter member, for example, it is possible to effectively prevent the head unit from accidentally moving to the component supply space during the replacement operation and interfering with the carriage. Thus, the cover unit has both the interference prevention function and the support function of the nozzle preparation unit, and the occupation ratio of the nozzle preparation unit in the apparatus main body can be effectively reduced.

  Further, the nozzle preparation unit may be provided on the shutter member so as to move with the forward / backward movement of the shutter member, and the nozzle preparation unit can be moved to a suitable position in conjunction with the carriage replacement work. For example, the shutter drive unit opens the opening by moving the shutter member away from the mounting space when the carriage is inserted into the apparatus main body, and the insertion of the carriage into the apparatus main body is not completed. You may comprise so that a shutter member may be moved so that it may approach mounting space in the incomplete insertion state, and an opening part may be closed. In this case, the nozzle preparation unit moves away from the mounting space in the insertion completion state (that is, the state where components are mounted), and conversely, in the incomplete insertion state (state where the carriage is replaced), the carriage is approaching the mounting space and the carriage is being replaced. It is possible to efficiently perform the nozzle preparation operation.

  Further, when the head unit is movable within a predetermined head movable region, the shutter drive unit moves the nozzle preparation unit outside the head movable region in the insertion completed state by the movement of the shutter member, while the insertion is not completed. It is preferable that the nozzle preparation unit be moved into the head movable region in the state. This is because in the insertion completed state (that is, the state in which components are mounted), the nozzle preparation unit has moved to the outside of the movable region of the head, so that the head unit can be shortened without considering interference with the nozzle preparation unit. It can be moved along the route. As a result, the tact time can be shortened and the operating rate of the apparatus can be further improved.

  As described above, according to the present invention, it is possible to mount the components supplied from the component supply unit mounted on the carriage on the substrate while reducing the occupation ratio of the nozzle preparation unit in the component mounting apparatus.

  FIG. 1 is an exploded perspective view showing a first embodiment of a component mounting apparatus according to the present invention. FIG. 2 is a plan view schematically showing the internal structure of the component mounting apparatus of FIG. FIG. 3 is a block diagram showing an electrical configuration of the component mounting apparatus of FIG. In the component mounting apparatus 1 according to the first embodiment, an apparatus main body 10 for mounting electronic components and a tape feeder 31 are set on a substrate P (FIG. 2) conveyed in a predetermined conveyance direction. And a collective exchanging cart 20 that is inserted and removed. In FIG. 1 and FIG. 2 and in each drawing described later, in order to clarify the arrangement relationship of each part of the apparatus, the transport direction of the substrate P is set to the “X direction” and is directed from the right hand side to the left hand side in FIG. The horizontal direction is referred to as “+ X direction”, and the reverse direction is referred to as “−X direction”. Further, among the horizontal directions orthogonal to the X direction, the front side of the apparatus is referred to as “+ Y direction” and the back side of the apparatus is referred to as “−Y direction”. Further, the upward direction and the downward direction in the vertical direction are referred to as “+ Z direction” and “−Z direction”, respectively.

  The internal space of the apparatus main body 10 is roughly divided into a mounting space 11 for executing a component mounting operation on the substrate P and a mounting-related operation related to the component mounting (substrate transport, imaging of a suction component, etc.) By inserting the collective exchange cart 20 into the apparatus main body 10, the tape feeder 31 is arranged and the component supply space 12 in which components can be supplied is partitioned by four cover units 50. The specific configuration of each cover unit 50 will be described in detail later.

  In the mounting space 11, as shown in FIG. 2, a mounting unit 40 for performing a mounting operation is provided. The mounting unit 40 includes two transport lanes 41 and 41 extending in parallel with the substrate transport direction X. Each transfer lane 41 has a common configuration, and carries the substrate P from the upstream side in the substrate transfer direction X, that is, from the (−X) direction side, and stops at a predetermined stop position 42 (the one-dot chain line in FIG. 1). The board carrying-in operation to be carried out and the board carrying-out operation for carrying out the board P that has received the component mounting at the stop position 42 to the downstream side in the board carrying direction X, that is, the (+ X) direction side are executed. At this time, each transport lane 41 has a configuration capable of stopping the substrate at each of two different stop positions 42 in the substrate transport direction X, for example. That is, each of the two transport lanes 41 includes two transport conveyors 411 and 412 extending in parallel with the board transport direction X. In the component mounting apparatus 1, the four transport conveyors 411, 412, and 412 are configured. 411 are arranged in parallel in the width direction Y. Of these, the two outer conveyors 411 and 411 are fixed conveyors fixed in the width direction Y, and the two inner conveyors 412 and 412 are movable conveyors movable in the width direction Y. . Therefore, by moving the movable conveyor 412 in the width direction Y, the width of the transport lane 41 can be adjusted according to the width of the substrate.

  Incidentally, the mode of substrate transfer in the two transfer lanes 41 is not limited to that illustrated in FIG. That is, FIG. 2 illustrates a case where two stop positions 42 are set in each of the two transfer lanes 41 and the substrate is transferred while setting a total of four stop positions 42. It is also possible to set a total of two stop positions 42 for each of the transport lanes 41 by setting one stop position 42 on the right side and the other on the left side. In addition, when the substrate width cannot be simultaneously executed in the two transfer lanes 41 due to the wide substrate width, the substrate transfer is executed only in one of the two transfer lanes, and the substrate is transferred in the other. Does not have to be executed.

  On both sides of the transport lane 41 in the width direction Y, component recognition cameras 43 are arranged in parallel in the board transport direction X. Further, the part recognition camera 43 extends to both sides in the width direction Y, and is partitioned by two cover units 50 on the (+ Y) direction side and by two cover units 50 on the (−Y) direction side. Each of these spaces functions as a component supply space 12. The collective exchange cart 20 can be inserted into and removed from the apparatus main body 10 at a position corresponding to each component supply space 12, and in this embodiment, up to four collective exchange carts 20 can be attached to the apparatus main body 10. It has become.

  FIG. 4 is a partial cross-sectional view of a collective exchange truck mounted on the apparatus main body. Each batch exchanging cart 20 can be mounted with a plurality of tape feeders 31 arranged in a direction parallel to the substrate transport direction X. By inserting the batch exchanging cart 20 into the apparatus main body 10, a plurality of tape feeders 31 can be attached. A component supply unit 30 is formed. In addition, as shown in FIG. 1, the collective exchanging cart 20 can be freely moved by a caster 21 provided at the lower end portion. More specifically, the collective exchanging carriage 20 includes a base portion 22 having casters 21 attached to the lower surface, a pair of left and right frames 23 erected from the base portion 22, and a feeder attached to the upper portion of the frame 23. Holding part 24. Further, the clamp body 13 (FIG. 3) is provided in the apparatus main body 10 at the insertion position of the collective change cart 20. While the clamp mechanism 13 is in the unlocked state, the batch change cart 20 is not fixed by the clamp mechanism 13, and the operator moves the handle cart 25 of the batch change cart 20 in the Y direction. The collective exchanging carriage 20 can be inserted into and removed from the apparatus main body 10. On the other hand, when the insertion of the collective exchange cart 20 into the apparatus main body 10 is completed (insertion complete state), the collective exchange cart 20 is fixed to the apparatus main body 10 by operating the clamp mechanism 13 provided in the apparatus main body 10. The In this way, the parts supply units 30 corresponding to the number of the collective change cart 20 are provided. In the present specification, a state that is not in the insertion completion state is referred to as an “insertion incomplete state”.

  In each component supply unit 30, a plurality of tape feeders 31 are arranged in the substrate transport direction X. Each tape feeder 31 has a schematic configuration in which a tape for storing small-sized electronic components such as an integrated circuit (IC), a transistor, and a capacitor is wound around a reel, and an electronic component is intermittently conveyed from the reel to a lane 41. Electronic parts are supplied by feeding to the side end. The type of feeder constituting the component supply unit 30 is not limited to a tape-type feeder, and may be a tray-type feeder that supplies electronic components while being placed on a tray.

  The tape feeder 31 configured as described above is disposed in the component supply space 12 in a state where insertion is completed, and components can be supplied. In order to mount the component supplied from the tape feeder 31 on the substrate P, the mounting unit 40 has two head units 45. Each head unit 45 has a plurality (10 in the present embodiment) of mounting heads 451 arranged in the X direction, and a nozzle at the tip of each mounting head 451 (reference numeral 452 in FIG. 9 described later). ), The components supplied by the component supply unit 30 are transferred to the substrate stopped at the stop position 42 by sucking the components from the end of the tape feeder 31 on the transport lane 41 side. In the component mounting apparatus 1, a head drive mechanism 46 for moving the head unit 45 is provided for each head unit 45. Specifically, two head driving mechanisms 46 are provided corresponding to the two component supply units 30 described above. Each head drive mechanism 46 is responsible for driving the corresponding head unit 45.

  Each head driving mechanism 46 has a configuration in which an X-axis beam 461 extending in the X direction is supported so as to be movable in the Y direction while supporting the head unit 45 so as to be movable in the X direction. An X-axis ball screw 462 that is attached to the head unit 45 and extends in the X direction and an X-axis motor 463 that rotationally drives the X-axis ball screw 462 are attached to the X-axis beam 461. When the X-axis motor 463 rotates the X-axis ball screw 462, the head unit 45 to which a nut (not shown) that is screwed to the X-axis ball screw 462 is fixed moves in the X direction along the X-axis beam 461. Each head driving mechanism 46 has a Y-axis ball screw 464 attached to one end of the X-axis beam 461 and extending in the Y direction above the transport lane 41, and a Y-axis motor 465 that rotationally drives the Y-axis ball screw 464. And have. When the Y-axis motor 463 rotationally drives the Y-axis ball screw 464, the X-axis beam 461 to which a nut (not shown) that engages with the Y-axis ball screw 464 is fixed moves in the Y direction along with the head unit 45. In this embodiment, the head unit 45 cannot move to the collective exchanging carriage 20 side beyond a certain range, and the movable region of the head unit 45 in the Y direction (see “head” in FIGS. 5A and 5B described later). The head unit 45 is not allowed to move to an area closer to the collective change cart 20 (corresponding to “outside of the head movable area” in FIGS. 5A and 5B described later). It is configured.

  Each head drive mechanism 46 configured in this manner rotates the X-axis motor 463 and the Y-axis motor 465 as appropriate, so that the head unit 45 is positioned between the component supply unit 30 and the stop position 42 above the substrate. Can be moved. Each mounting head 451 provided in the head unit 45 can be moved up and down (moved in the Z-axis direction) with respect to the head unit 45 by a nozzle lifting / lowering driving mechanism (not shown), and the nozzle central axis by a nozzle rotating driving mechanism (not shown). It can be rotated around. Among these drive mechanisms, the nozzle raising / lowering drive mechanism raises and lowers the mounting head 451 between a lowered position (falling end) when performing suction or mounting and an elevated position (upward end) when carrying. The nozzle (reference numeral 452 in FIG. 9) is configured to be movable up and down. On the other hand, the nozzle rotation drive mechanism is a mechanism for rotating the nozzle as necessary, and can rotate and position the component in a predetermined R-axis direction during mounting. These drive mechanisms are respectively constituted by a Z-axis motor 466, an R-axis motor 467, and a predetermined power transmission mechanism. The motor control unit 63 of the control unit 60 causes the Z-axis motor 466 and the R-axis motor 467 to be connected. By controlling the drive, each mounting head 451 is moved in the Z direction and the R direction. As a result, the head unit 45 can pick up the components supplied by the component supply unit 30 with the mounting head 451 and transfer them onto the substrate P stopped at the stop position 42.

  In addition, for each of the two component supply units 30, a component recognition camera 43 is disposed adjacent to the inside in the Y direction (from the conveyance lane 41 side). Thus, the component recognition camera 43 is provided between the component supply unit 30 and the transport lane 41 (in other words, the movement path of the head unit 45). The component recognition camera 43 is arranged facing upward in parallel to the vertical direction Z, and is held by the head unit 45 passing through the upper side, or a position recognition mark attached to the head unit 45 (not shown). Image. Each head unit 45 is provided with a substrate recognition camera 47 for imaging a fiducial mark (not shown) attached to the substrate P.

  Next, the configuration of the cover unit 50 will be described with reference to FIGS. 1, 4, 5A, 5B, 6 and 7. FIG. FIG. 5A is a perspective view showing the cover unit with the shutter opened, and FIG. 5B is a perspective view showing the cover unit with the shutter closed. FIG. 6 is a partial configuration diagram of the cover unit of FIGS. 5A and 5B, showing a top cover and a shutter member. FIG. 7 is a diagram schematically showing the operation of the top cover and the shutter member. Of these drawings, FIGS. 5A and 5B show a state in which the drive cover 55 (see FIG. 1) for protecting the drive valve group for controlling the cover drive mechanism is removed. In FIGS. 6 and 7, the shutter member is provided with dots in order to clearly distinguish the top cover and the shutter member. In the present embodiment, the suction pad 81 is attached to the shutter member. An adhesive material is applied to the upper surface of the suction pad 81, and when the tip of a nozzle (reference numeral 452 in FIG. 9) is pressed against the upper surface (+ Z side main surface) of the suction pad 81, it adheres to the tip. Dust and solder residue are trapped on the suction pad 81 and removed from the nozzle. Such nozzle cleaning processing can be executed during the replacement processing of the batch replacement cart 20 as will be described in detail later. 2, FIG. 5A, FIG. 5B, FIG. 6, FIG. 7 and FIG. 9 are hatched in order to distinguish the suction pad 81 from other components.

  The cover unit 50 has a function of partitioning the mounting space 11 and the component supply space 12 by being attached to the apparatus main body 10 as shown in FIGS. 1 and 4. In the present embodiment, four cover units 50 are provided. Are disposed, but both have the same configuration. More specifically, the cover unit 50 is moved in the Y direction and the Z direction with respect to the cover body 51, the top cover 52 attached to the cover body 51 so as to be movable in the vertical direction Z, and the top cover 52. A freely mounted shutter member 53, a top cover 52 and a cover drive mechanism 54 for driving the shutter member 53, and a drive cover 55 (see FIG. 1) for protecting the drive valve group are provided. In the cover body 51, as shown in FIGS. 5A and 5B, the pair of side plates 511 and 511 are arranged in the X direction so as to be slightly wider than the X direction dimension of the collective exchanging carriage 20. In each side plate 511, a second flat plate portion 511b having a substantially rectangular shape is extended in the (−Y) direction from the center of the (−Y) side portion of the first flat plate portion 511a having a substantially rectangular shape. Further, the top plate 512 is fixed from the upper side of the first flat plate portion 511a of the side plate 511, 511 to the side of the (−Y) direction, and the cover body 51 is secured by the side plate 511, 511 and the top plate 512. Is configured.

  The cover unit 50 shown in FIGS. 5A and 5B is open on the left side so that the carriage can enter as shown in FIG. 1, but the lower side of one side plate 511 is on the inner wall of the apparatus main body 10. Connected without gaps. In the present embodiment, two cover units 50 are provided in the lateral direction, but the side plate 511 on the side that is not the inner wall of the apparatus has no gap with the adjacent side plate 511. Further, the left end portion of the top rate 512 extends to a position where there is no gap with the lower end portion of the front wall of the apparatus main body 10. Also, the lower end of the right end portion of the top cover 52 and the right end portion of the side plate 511 are open, but this portion has a wall on the apparatus main body 10 side as shown in FIG. This wall is a wall forming a duct through which the tape after the electronic components discharged by the tape feeder 31 are taken out is sent downward. Thus, the component supply space is separated from the component mounting space, and only the opening 522 is open. Therefore, when the opening 522 is closed by the shutter member 53, the component supply space is completely isolated from the component mounting space.

  In each side plate 511, the main components of the cover drive mechanism 54 are attached from the first flat plate portion 511a to the second flat plate portion 511b. Since the pair of cover drive mechanisms 54 provided on both sides in the X direction have the same configuration, only the cover drive mechanism 54 on the (−X) direction side will be described here, and the (+ X) direction side will be described. The description of the cover driving mechanism 54 will be omitted. In the cover driving mechanism 54, the front stopper 541a and the rear stopper 541b are fixed to the first flat plate portion 511a and the second flat plate portion 511b, respectively, at the same height in the vertical direction Z. Further, the shaft member 542 extends through the front stopper 541a and the rear stopper 541b in the Y direction while being separated from the side plate 511 in the (−X) direction side, and is supported by both stoppers 541a and 541b. However, it is movable in the Y direction. Further, the end portion on the (+ Y) direction side of the shaft member 542 is connected to the piston portion of the drive cylinder 544 by the link plate 543. For this reason, when the piston part of the drive cylinder 544 extends in the (+ Y) direction, the shaft member 542 moves in the (+ Y) direction accordingly. Conversely, when the piston portion of the drive cylinder 544 contracts in the (−Y) direction, the shaft member 542 moves in the (−Y) direction accordingly. By the movement of the shaft member 542 in the Y direction, the top cover 52 and the shutter member 53 are moved up and down and the shutter member 53 is moved in the Y direction by a cam mechanism configured as described below.

  In the central portion of the shaft member 542, as shown in FIGS. 6 and 7, three pins 542a to 542c are erected side by side in the (−X) direction side and arranged in the (+ X) direction side. Two pins 542d and 542e are erected. Among these, on the (+ X) direction side, the (−X) direction side support portion 521 of the top cover 52 is located in a gap formed between the shaft member 542 and the side plate 511. The (−X) direction side support portion 521 is provided with two cam grooves 521a and 521b. Each of these cam grooves 521a and 521b has a configuration in which two horizontal parts extending in the Y direction are provided by shifting in the vertical direction Z, and both horizontal parts are connected at an oblique part. The pins 542d and 542e are fitted in the cam grooves 521a and 521b, respectively. For this reason, as shown in the left column of FIG. 7, when the shaft member 542 moves in the (−Y) direction, the pins 542d and 542e slide in the (−Y) direction in the cam grooves 521a and 521b, respectively. It rises by the amount of deviation of the horizontal part in the direction. On the contrary, when the shaft member 542 moves in the (+ Y) direction, the pins 542d and 542e slide in the (+ Y) direction in the cam grooves 521a and 521b, respectively, and descend by the amount of deviation of the horizontal portion in the vertical direction. In the present embodiment, the (−Y) direction side end and the (+ Y) direction side end of the top cover 52 are configured to always contact the stoppers 541a and 541b, respectively. 52 is stationary at a fixed position and can be moved up and down only in the vertical direction Z. Here, instead of the stoppers 541a and 541b, the movement of the top cover 52 in the Y direction may be restricted by another stopper.

  On the other hand, on the (−X) direction side, the pins 542a to 542c are fitted into elongated holes 531a to 531c provided in the (−X) direction side support portion 531 of the shutter member 53, respectively. Of these, the elongated holes 531a and 531c extend slightly obliquely, and C-shaped fasteners (not shown) are attached to the tips of the pins 542a and 542c inserted into the elongated holes 531a and 531c, respectively. Yes. The remaining slot 531b extends in the Y direction, and one end of the spring member 533 is locked to the tip of the pin 542b fitted into the slot 531b. Further, the other end of the spring member 533 is fixed to the (−X) direction side support portion 531 of the shutter member 53.

  When the shaft member 542 moves in the (−Y) direction in the order of (a), (b), (c), and (d) in FIG. 7, the shutter member 53 accordingly moves in the (−Y) direction, and the top It is located immediately above the opening 522 provided in the cover 52 and closes the opening 522 by closing it from above. Further, the suction pad 81 together with the shutter member 53 is moved from the head movable region to the head movable region 453 and positioned. In this state, when the head unit 45 moves to a position just above the suction pad 81 and lowers the mounting head 451, the nozzle (reference numeral 452 in FIG. 9) attached to the tip of the mounting head 451 becomes the surface of the suction pad 81. Nozzle cleaning is performed in contact with the nozzle.

  During this movement, the pins 542a and 542c slide in the long holes 531a and 531c to raise the shutter member 53, but the spring member 533 raises slightly earlier than the timing of raising the top cover 52. It is configured as follows. Immediately after closing the opening 522 by the shutter member 53 in this way, the (−Y) direction side end portion of the (−X) direction side support portion 531 is locked to the front stopper 541a and the shutter member 53 and the shaft member 542 are engaged. Movement in the (−Y) direction is restricted.

  On the contrary, when the shaft member 542 moves in the (+ Y) direction, the shutter member 53 also moves in the (+ Y) direction, and is separated from the opening 522 in the (+ Y) direction to open the opening 522. Further, the suction pad 81 together with the shutter member 53 moves from the head movable region 453 to the outside of the head movable region and is positioned. During this movement, the pins 542a and 542c slide in the long holes 531a and 531c to lower the shutter member 53. However, the spring member 533 lowers the head cover 52 slightly later than the lowering timing of the top cover 52. It is configured as follows. Thus, immediately after the shutter member 53 is retracted from the opening 522, the (+ Y) direction side end portion of the (−X) direction support portion 531 is locked to the rear stopper 541 b and the shutter member 53 of the shutter member 53 together with the shaft member 542 is engaged. Movement in the (+ Y) direction is restricted. In this embodiment, as shown in FIGS. 5A and 5B, the stopper 541c is fixed to the side plate 511 on the (+ Y) direction side of the piston portion of the drive cylinder 544, and the shaft member 542 is excessively (+ Y) direction. To move to.

  Further, in order to detect the open / closed state of the opening 522 by the shutter member 53, in the present embodiment, a projecting site projecting in the (−Z) direction from the lower side of the (−X) direction side support site 531 is provided. Sensors 545a and 545b for detection are provided. That is, when the opening 522 is closed as shown in FIG. 5A, the sensor 545a detects the shutter member 53, while when the opening 522 is opened, the sensor 545b detects the shutter member 53, as shown in FIG. 5B. When the opening 522 is closed, the sensor 545a detects the shutter member 53. Detection signals output from these sensors 545a and 545b are sent to the control unit.

  Next, the configuration of the control unit will be described with reference to FIG. The control unit 60 is provided at an appropriate position inside the apparatus main body, and is a well-known CPU (Central Processing Unit) that executes logical operations, a ROM (Read Only Memory) that stores initial settings and the like, and various devices that are operating. It is composed of a RAM (Random Access Memory) that temporarily stores data.

  Functionally, the control unit 60 includes an arithmetic processing unit 61, a storage unit 62, a motor control unit 63, an image processing unit 64, a clamp control unit 65, a shutter control unit 66, a server communication control unit 67, and a feeder communication control unit 68. It has.

  The motor control unit 63 controls driving of the X-axis motor 463, the Y-axis motor 465, the Z-axis motor 466, and the R-axis motor 467. The image processing unit 64 takes in image data from the component recognition camera 43 and the board recognition camera 47 and performs image processing such as binarization. The clamp controller 65 has a function of switching between fixing and releasing the batch exchanging carriage 20 to the apparatus main body 10 by the clamp mechanism 13. The shutter controller 66 controls the drive cylinder 544 based on detection signals from the sensors 545 a and 545 b provided in the cover unit 50 to switch between opening and closing of the opening 522 by the shutter member 53. The server communication control unit 67 communicates information and the like with a server (not shown). The feeder communication control unit 68 communicates information and the like with the feeder control unit 32 provided in each tape feeder 31.

  The storage unit 62 includes storage means such as a mounting program for storing component mounting processing and cart replacement processing programs and various data necessary for mounting, transport system data storage means for storing various data related to the transport system for transporting the printed circuit board, and It functions as facility-specific data storage means for storing data specific to each facility of the component mounting apparatus 1.

  The arithmetic processing unit 61 controls the motor control unit 63, the image processing unit 64, the clamp control unit 65, and the shutter control unit 66 in accordance with a program stored in the storage unit 62. In particular, the arithmetic processing unit 61 performs component mounting processing by the mounting unit 40 in parallel with the replacement processing of the collective replacement cart 20 (= cart unclamping processing + cart cart clamping processing) as described below. In this way, the arithmetic processing unit 61 functions as a cart replacement processing unit 611 and a mounting processing unit 612. In addition, the code | symbol 70 in FIG. 3 is a display unit, and it is connected with the control unit 60, and besides being a function which displays the operation state of the component mounting apparatus 1, it is comprised with a touch panel and can also serve as an input terminal which receives the input from an operator. Function.

  In the component mounting apparatus 1, when changing the kind of the board | substrate P as above mentioned, the tape feeder 31 used with the change may be replaced | exchanged and a setup may be switched. In order to facilitate this setup change, a collective change cart 20 has been used conventionally. That is, in accordance with the change in the type of the substrate P, the collective exchanging cart 20 corresponding to the substrate P after the change is executed after performing the cart unclamping process for removing the collective exchanging cart 20 from the apparatus main assembly 10 of the apparatus main assembly 10. Carriage clamp processing to be inserted and set in the main body 10 is executed. Further, since the component supply space 12 is partitioned from the mounting space 11 inside the apparatus main body 10, the component mounting and component by the mounting unit 40 are performed during the cart replacement process (= cart unclamp process + cart clamp process). Mounting-related operations related to mounting (substrate conveyance, picking up of suction parts, etc.) and nozzle cleaning processing are executed. Hereinafter, the cart replacement process and the nozzle cleaning performed during the cart replacement process will be described with reference to the drawings.

  8A and 8B are flowcharts showing the contents of the cart replacement process executed by the component mounting apparatus shown in FIG. FIG. 9 is a diagram schematically showing a component holding operation performed during the mounting process and a nozzle cleaning operation performed during the cart replacement process. When the operator operates the display unit 70 to give a cart unclamping command (corresponding to the “extraction command” of the present invention) to the control unit 60, the control unit 60 controls each part of the apparatus as follows to perform the cart unclamping process. Execute. The control unit 60 confirms the operation state of the actuator in the mounting unit 40, and the motors 463, 465, 466, 467, etc. are in the ON state, and the component mounting and mounting-related operations by the mounting unit 40 are possible In step S103, the cart unclamping operation is started. On the other hand, when the mounting unit 40 is in a stopped state (when “NO” in step S101), they are switched to the driving state (step S102), and then the process proceeds to the next step S103, where the cart unclamping operation is performed. Execute. Accordingly, in parallel with the cart replacement operation, the tape feeder other than the tape feeder 31 that is the target of the cart unclamping operation, that is, the tape feeder mounted on the batch replacement cart 20 in the insertion completed state with respect to the apparatus main body 10. The components supplied from 31 can be mounted on the substrate P. Further, as described in detail below, a nozzle cleaning operation is performed in parallel with the carriage replacement process as one of the nozzle preparation operations for the component mounting process after replacement.

  In step S103, a message indicating that the cart clamp switch (not shown) is switched from the ON state to the OFF state is displayed on the display unit 70, and the operator waits for the operator to switch it to the OFF state. When the cart clamp switch is switched to the OFF state, the control unit 60 contracts the piston portion of the drive cylinder 544 to move the shutter member 53 toward the opening 522 and closes the opening 522 (step S104). . When the shutter member 53 is moved to the opening 522, the top cover 52 and the shutter member 53 are in close proximity to the tape feeder 31 (positions shown in the column (a) in FIG. 7) in conjunction with the forward movement. ) To the separation position (the position shown in the column (d) in FIG. 7) that is separated upward, and moves away from the batch exchanging carriage 20. Therefore, when removing the collective exchange cart 20 from the apparatus main body 10, it is possible to effectively prevent the tape feeder 31 mounted on the collective exchange cart 20 from interfering with the top cover 52 because the collective exchanging cart 20 slightly vibrates up and down. can do. This is the same as when the collective exchanging cart 20 described later is inserted.

  Further, as the shutter member 53 moves forward, the suction pad 81 moves from the outside of the head movable region to the head movable region 453 as shown in FIG. 9 and is positioned immediately above the opening 522. Thereby, preparation for nozzle cleaning is completed. This state is continued until the shutter member 53 moves in the (+ Y) direction from the opening 522 to open the opening 522.

  When the shutter member 53 is positioned above the opening 522, the sensor 545a detects the closing of the opening 522 and outputs it to the control unit 60. However, the detection signal is not detected until a predetermined time elapses from the execution of step S104. Is not output ("NO" in step S105), the control unit 60 determines that a shutter failure has occurred, stops the error, and displays that fact on the display unit 70 (step S106). On the other hand, when the detection signal is output from the sensor 545a within a predetermined time and it is confirmed that the shutter member 53 is closed by closing the opening 522 ("YES" in step S105), the control unit 60 clamps. The clamp of the collective exchanging cart 20 by the mechanism 13 (FIG. 3) is released (step S107).

  Here, when the clamp release cannot be confirmed (“NO” in step S108), the control unit 60 determines that a clamp release failure has occurred, stops the error, and notifies the display unit 70 to that effect. (Step S109). On the other hand, if the release of the clamp is confirmed (“YES” in step S108), the control unit 60 displays a message on the display unit 70 that the batch replacement cart 20 can be removed, and the batch replacement cart 20 by the operator. (Step S110). In response to this, the operator removes the collective exchanging cart 20 from the apparatus main body 10.

  In addition, when the replacement work of the batch exchanging carriage 20 is started in this way, the control unit 60 determines whether there is a nozzle cleaning request (step S111). Here, in order to smoothly mount the components after the cart replacement process, it is desirable to remove dust and solder residue from the tip of the nozzle 452. Therefore, if nozzle cleaning associated with the carriage replacement is not requested, a message to that effect is displayed on the display unit 70 (step S112). On the other hand, when the nozzle cleaning request is confirmed, the control unit 60 proceeds to the next step S113 and starts nozzle cleaning. More specifically, the control unit 60 controls the motor control unit 63 to move the head unit 45 to a position directly above the suction pad 81 (see the dotted line in the column (b) in FIG. 9). Subsequently, the control unit 60 controls the motor control unit 63 to lower the mounting head 451 to which the nozzle 452 is attached and press the tip of the nozzle 452 against the suction pad 81, and after a certain time has elapsed, The mounting head 451 is pulled up. As a result, dust or solder residue adhering to the tip of the nozzle 452 is transferred to the suction pad 81 and removed from the nozzle 452, that is, a nozzle cleaning operation is executed.

  This nozzle cleaning operation is continuously performed even during the clamping process of the batch exchanging carriage 20. This cart clamping process is executed as shown in FIG. 8B. That is, when the operator operates the display unit 70 to give a cart clamping command to the control unit 60, the arithmetic processing unit 61 of the control unit 60 controls each part of the apparatus as follows. In step S114, the control unit 60 displays a message for prompting the insertion of the collective exchange cart 20 on the display unit 70, and the operator inserts the collective exchanging cart 20 into the apparatus main body 10 in response to this. In addition, when it is confirmed that the batch exchange cart 20 has been inserted and the insertion has been completed, the control unit 60 determines whether or not the batch exchange cart 20 has been detected by a forward end sensor (not shown) during a certain period of time. Confirmation (step S115). Here, if the collective exchanging cart 20 cannot be detected within a certain time, the control unit 60 determines that an insertion failure has occurred, stops the error, and displays that fact on the display unit 70. (Step S116). On the other hand, when it is confirmed that the collective exchanging cart 20 has been inserted into a predetermined position of the apparatus body 10 (“YES” in step S116), the control unit 60 changes the cart clamp switch (not shown) from the OFF state to the ON state. A message to switch is displayed on the display unit 70 and waits for the operator to switch to the ON state (step S117). When the cart clamp switch is switched to the ON state, the control unit 60 clamps the collective exchanging cart 20 on the apparatus main body 10 by the clamp mechanism 13 (FIG. 3) (step S118).

  While the above-described nozzle cleaning operation is performed during the clamp process, the control unit determines whether or not the nozzle cleaning has been completed for the desired nozzle 452 at the time when step S118 is performed. 60 determines (step S119). When the nozzle cleaning is not completed (“NO” in step S119), the carriage clamping process is temporarily waited (step S120). This standby process is repeated until “YES” is determined in step S119. When the completion of nozzle cleaning is confirmed, the control unit 60 further confirms the carriage clamp (step S121).

  Here, when the carriage clamp cannot be confirmed (“NO” in step S121), the control unit 60 determines that a clamping failure has occurred, stops the error, and informs the display unit 70 of that fact. It is displayed (step S122). On the other hand, if the cart clamp is confirmed (“YES” in step S121), the control unit 60 obtains the cart ID attached to the inserted batch exchanging cart 20 (step S123). This “cart ID” is unique identification information given to each batch exchanging cart 20, and the control unit 60 reads the cart ID from the batch exchanging cart 20 so that the batch exchanging cart 20 inserted by the operator is desired. It is confirmed whether it is a thing (step S124). When it is not the desired one (“NO” in step S124), the control unit 60 determines that a different carriage has been inserted, stops the error, and displays that fact on the display unit 70 (step S125). .

  On the other hand, when it is confirmed that the desired collective exchanging cart 20 is inserted, the control unit 60 extends the piston portion of the drive cylinder 544 to retract the shutter member 53 from the opening portion 522 in the (+ Y) direction, thereby opening the opening portion 522. Is opened (step S126). Further, the suction pad 81 is moved from the head movable area 453 to the outside of the head movable area by retracting the shutter member 53. As a result, as shown in the column (a) in FIG. 9, the head unit 45 can access the tape feeder 31 attached to the batch exchanging carriage 20 through the opening 522. The components supplied from the tape feeder 31 are mounted on the substrate P by the mounting head 451 of the head unit 45. When the shutter member 53 is retracted from the opening 522, the top cover 52 is moved from the separation position (position shown in the column (d) in FIG. 7) to the proximity position (in FIG. The position is lowered to the position shown in the column a) and close to the tape feeder 31, and the distance between the opening 522 and the part is shortened. For this reason, the ascending / descending distance of the mounting head 451 at the time of component adsorption by the tip portion (nozzle) of the mounting head 451 through the opening 522 and the removal of the adsorbed component is reduced, and the time required for component mounting can be shortened. Further, when the suction pad 81 is positioned on the movement path of the head unit 45, this causes a deterioration in tact time. However, in the present embodiment, the suction pad 81 is positioned outside the head movable region. 45 can be moved in the shortest course, and the tact time can be kept good.

  As described above, in the first embodiment described above, the inside of the apparatus main body 10 is divided into the mounting space 11 and the component supply space 12 by the cover unit 50, and the replacement processing (= unclamp processing and clamping processing) of the collective replacement cart 20 is performed. Even during the operation, the component mounting operation to the board P is executed in the mounting space 11. Further, in parallel with the carriage replacement process, it is possible to perform a nozzle cleaning operation as a nozzle preparation operation, and the operating rate of the component mounting apparatus 1 can be improved. In the above embodiment, the suction pad 81 for performing the nozzle cleaning operation is provided on the shutter member 53 of the cover unit 50 and functions as the “nozzle preparation unit” of the present invention. For this reason, the occupation rate of the suction pad 81 can be reduced as compared with the conventional device in which the suction pad 81 is provided in the mounting space.

  In addition, by controlling opening and closing of the opening 522 by the shutter member 53, for example, it is possible to effectively prevent the head unit 45 from moving to the component supply space 12 and interfering with the collective replacement carriage 20 during replacement work. Can do. Thus, the cover unit 50 has both the interference prevention function and the support function of the nozzle preparation unit, and can effectively reduce the occupation rate of the suction pads 81 in the apparatus main body 10.

  Further, the suction pad 81 is provided on the shutter member 53 and moves together with the forward / backward movement of the shutter member 53. More specifically, when the insertion of the carriage 20 into the apparatus main body 10 is completed, the shutter member 53 is moved away from the mounting space 11 to open the opening 522, and the carriage 20 to the apparatus main body 10 is opened. The shutter member 53 is moved so as to approach the mounting space 11 in an incomplete insertion state where the insertion is not completed, and the opening 522 is closed. For this reason, the suction pad 81 is separated from the mounting space 11 in the insertion completed state (that is, the state where components are mounted), and conversely, in the insertion incomplete state (the state where the carriage is replaced), the suction pad 81 approaches the mounting space 11 and replaces the carriage. It is possible to efficiently perform the nozzle cleaning operation in the inside. Therefore, component mounting can be performed at a high operating rate.

  In the first embodiment, the opening 522 is provided only in a part of the cover unit 50, and the mounting head 451 of the head unit 45 accesses the tape feeder 31 through the opening 522. . In particular, in this embodiment, as shown in FIG. 2 and FIG. 5B, the opening 522 extends in the arrangement direction X so as to face the front end (component supply position) of the tape feeder 31 arranged in the X direction from above. The opening 522 is specialized for taking out parts. Therefore, the access from the mounting space 11 to the component supply space 12 and the access from the component supply space 12 to the mounting space 11 are limited to a limited area, and it is possible to effectively suppress the occurrence of inconvenient interference. it can.

  In the first embodiment, the shutter member 53 moves forward and backward with respect to the opening 522 to control opening and closing of the opening 522, and the opening 522 is closed by the shutter member 53 when the collective exchanging cart 20 is replaced. Mutual access between the mounting space 11 and the component supply space 12 is restricted. Therefore, for example, it is possible to effectively prevent the mounting head 451 from erroneously moving into the component supply space 12 and interfering with the collective replacement carriage 20 during the replacement work.

  Further, in the first embodiment, in order to move the shutter member 53 forward and backward, a cover drive mechanism 54 is provided on each of the side plates 511, and both the cover drive mechanisms 54 are operated in synchronization by the control unit 60. . For this reason, opening and closing of the opening 522 by the shutter member 53 can be performed stably and reliably.

  In the first embodiment, the top cover 52 provided with the opening 522 is configured to move up and down in conjunction with the forward and backward movement of the shutter member 53. That is, when the insertion of the batch exchanging carriage 20 is completed, the top cover 52 is close to the tape feeder 31 to shorten the ascending / descending distance of the mounting head 451 to shorten the tact time required for component mounting. Further, when exchanging the collective exchanging cart 20, the top cover 52 moves upward to increase the distance from the tape feeder 31 in the vertical direction Z. For this reason, the collective exchanging cart 20 can be exchanged stably.

  In the first embodiment described above, the tape feeder 31 corresponds to an example of the “component supply unit” of the present invention. The top cover 52 corresponds to an example of the “cover member” of the present invention. Further, the cover driving mechanism 54 corresponds to an example of the “shutter driving unit” of the present invention. Further, the exchange process of the collective exchange cart 20 (= cart unclamp process + cart clamp process) corresponds to an example of the “cart exchange process” of the present invention, and step S113 executed during the cart replacement process is the present invention. This corresponds to an example of a “nozzle preparation step”.

  The present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described one without departing from the spirit of the present invention. For example, in the above embodiment, the suction pad 81 is provided as the nozzle preparation unit, and the nozzle cleaning is performed by the suction pad 81 as the nozzle preparation operation. However, the nozzle preparation unit and the nozzle preparation operation are not limited to this. The preparation operation for mounting the component by the nozzle 452 is included in the “nozzle preparation operation”, and the unit for executing the nozzle preparation operation is included in the “nozzle preparation unit” of the present invention. For example, there is a case where the nozzle needs to be changed along with the setup change. Therefore, for example, as shown in FIG. 10, a nozzle exchanger 82 for placing a replacement nozzle 452 and replacing it with the nozzle 452 of the head unit 45 may be provided in the shutter member 53 as a nozzle preparation unit. Similarly to the embodiment, the nozzle replacement operation may be executed as the nozzle preparation operation during the replacement of the carriage (second embodiment). Since the nozzle exchanger 82 is already widely used in the component mounting technology and is well known, the description of the configuration and operation thereof will be omitted.

  Further, as described in, for example, Japanese Patent Application Laid-Open No. 2010-135534, a drive error is compensated with time due to deterioration over time of a drive mechanism portion for moving the head unit 45 and the substrate P relative to each other. Therefore, an operation for deriving a component mounting error by the nozzle (hereinafter referred to as “error deriving operation”) may be performed as a nozzle preparation operation. Therefore, in order to perform an error deriving operation, for example, a shutter is used as a nozzle preparation unit with a mock mounting table 83 on which a detection jig or the like that picks up a nozzle and picks up an image with a component recognition camera and detects a drive error of the drive unit is placed. Similar to the first embodiment, the error derivation operation may be executed as a nozzle preparation operation during the replacement of the carriage (third embodiment).

Moreover, in the said embodiment, although the suction pad 81 which functions as a nozzle cleaning part, the nozzle exchanger 82, or the simulation mounting table 83 is provided with respect to the shutter member 53, you may provide combining these. Further, the installation position of the suction pad 81, the nozzle exchanger 82 or the simulation mounting table 83 is not limited to the shutter member 53, and all or part of them may be provided on the top cover 52. Of course, some of them may be provided on the shutter member 53 and the rest may be provided on the top cover 52. Furthermore, the top cover 52 may be provided on the −Y direction side of the opening 522 or may be provided on the + Y direction side. However, in the case of the + Y direction side, it is necessary to provide further on the + Y side than the retracted position of the shutter member 53, and the head operating area is extended to the + Y side to the installation position of the suction pad 81, the nozzle exchanger 82 or the simulation mounting table 83. There is a need. Moreover, it is preferable that the installation position of the suction pad 81, the nozzle exchanger 82, or the simulation mounting table 83 is a horizontal plane.
Although these installation positions are on the cover unit 52, they are also directly above (in the vertical direction) the collective exchange cart 20 installed in the apparatus main body 10, and the collective exchange cart 20 is installed in the apparatus main assembly 10. It is also a position directly above the tape feeder 31 installed at a position where it can be operated. If the position is above the tape feeder 31, the carriage may not be replaceable from the apparatus main body and may be fixed, and it is not necessary to occupy the −Y side from the feeder.

  In the above embodiment, the cover driving mechanism 54 is provided on each side plate 511 and the shutter member 53 and the top cover 52 are driven in synchronization with each other. However, the cover driving mechanism 54 is provided only on one side plate 511. In this case, it is desirable to provide a guide mechanism in the Y direction on the other side plate 511.

  In the first embodiment, the nozzle cleaning is performed as an example of the “nozzle preparation operation” according to the present invention during the carriage replacement. However, the suction pad (nozzle preparation unit) 81 is used as the cover unit 50 (however, the head is movable). The nozzle cleaning operation may be appropriately executed during the mounting operation. The same applies to other nozzle preparation operations.

  Further, in the above embodiment, the present invention is applied to the so-called dual lane type component mounting apparatus 1 having two transport lanes 41, but the application target of the present invention is not limited to this, and transport The method, the number of head units, the number and arrangement of mounting heads, etc. are arbitrary, and can be applied to any component mounting apparatus using the collective exchanging cart 20.

  The present invention can be applied to all component mounting techniques for mounting a component supplied from a component supply unit mounted on a carriage on a substrate.
