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, the operation of the mounting unit such as the head unit is stopped in order to prevent unexpected interference from occurring in the apparatus main body during the replacement of the collective change cart.

JP 2009-231734 A

  As described above, in the conventional apparatus, the component mounting operation is stopped at the time of replacing the collective exchanging cart, that is, while the collective exchanging cart is being inserted into and removed from the apparatus main body. This stop processing is one of the main factors that lower the operating rate of the component mounting apparatus, and improvement is desired.

  This invention is made in view of the said subject, and it aims at improving the operation rate of an apparatus in the component mounting technique which mounts the component supplied from the component supply unit with which the trolley | bogie was mounted | worn on a board | substrate.

  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 carriage for the device main body by separating the mounting space from the component supply space in the device main body And a cover unit capable of executing a component mounting operation on a board in a mounting space during exchanging the cart by insertion and extraction.

  According to another aspect of the present invention, a carriage equipped with a component supply unit is inserted into the apparatus main body to be arranged in a component supply space in the apparatus main body, and the components supplied from the component supply unit are arranged in the apparatus main body. A component mounting method for mounting on a board in a mounting space, wherein a carriage replacement process is performed in which the carriage is replaced by inserting and removing the carriage with respect to the apparatus body while partitioning the mounting space and the component supply space by the cover unit, and in the mounting space during the carriage replacement. And a mounting process for mounting components on the board.

  Here, a head unit that performs a mounting operation is provided, the cover unit has an opening that communicates the component supply space and the mounting space, and the head unit is in an insertion completed state in which insertion into the apparatus main body of the carriage is completed. The components supplied from the component supply unit may be configured to be held through the opening and perform the mounting operation. In this way, the opening is used to hold the component by the head unit, and access to the component supply space from the mounting space and access from the component supply space to the mounting space are limited to the opening, causing inconvenience. Can be effectively suppressed.

  Further, the cover unit includes a cover member provided with an opening, a shutter member that is movable forward and backward with respect to the opening, and a shutter driving unit that opens and closes the opening by moving the shutter member forward and backward with respect to the opening. The shutter drive unit is configured to open the opening when the carriage is completely inserted into the apparatus main body and to close the opening when the carriage is not completely inserted into the apparatus main body. May be. 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.

  In addition, a plurality of component supply units are arranged side by side in a predetermined arrangement direction on the carriage, and the opening extends in the arrangement direction so as to face the plurality of component supply units from above. When the insertion is not completed, the shutter member is opened. You may comprise so that a part may be covered and covered from upper direction. Accordingly, it is possible to cope with a case where a carriage on which a plurality of component supply units are mounted is replaced.

  In addition, by configuring the shutter drive unit to be disposed on at least one side in the horizontal direction orthogonal to the advancing / retreating direction of the shutter member, the opening portion can be opened and closed by the shutter member. By providing shutter driving portions on both sides in the horizontal direction, the opening and closing can be performed more stably.

  Further, the shutter driving unit may be configured to move the shutter member in a direction away from the mounting space to open the opening, thereby reducing the distance between the opening and the mounting space, and reducing the tact time. It can be effectively reduced.

  In addition, the cover member is provided so as to be movable in the vertical direction, and the cover unit is positioned at a close position close to the component supply unit in the insertion completed state, while it is positioned at a separated position above the close position in the insertion incomplete state. You may comprise so that it may have the cover raising / lowering part to be made. Thus, when the cover member is positioned in the proximity position in the insertion completed state, the moving distance of the head unit in the vertical direction can be shortened, and the tact time required for component mounting can be shortened. On the other hand, since the cover member is positioned at the separated position in the incomplete insertion state, the distance to the component supply unit in the vertical direction is increased, and the carriage can be stably replaced.

  Further, in the component mounting apparatus in which the cover unit has an opening that communicates the component supply space and the mounting space, and a shutter member that opens and closes the opening to open and close the opening, It may be configured to include a step of detecting an insertion completion state in which the insertion of the carriage into the vehicle is completed, and a step of opening the opening portion by moving the shutter member from the opening portion in response to the detection of the insertion completion state. . By detecting this insertion completion state, it can be ascertained whether or not the component supply unit is arranged in the component supply space, and the opening is opened only when the component supply unit is arranged in the component supply space. Mounting by components supplied from the component supply unit is possible. Therefore, it is possible to reliably suppress the occurrence of inconvenient interference.

  In addition, the mounting process includes mounting a component by sucking and holding the component supplied from the component supply unit arranged in the component supply space by the head unit through the opening, and a command for removing the carriage from the apparatus main body. And the step of retracting the head unit from the opening by stopping the suction of the parts by the head unit, and after the carriage replacement process confirms that the head unit has been retracted from the opening, the shutter member is opened. And a step of closing the opening by moving to the portion. In this case, since the shutter member moves to the opening after the head unit is retracted from the opening, interference between the head unit and the shutter member can be reliably prevented.

  In addition, the mounting process includes a step of repeatedly performing a mounting operation of mounting a component by sucking and holding the component supplied from the component supply unit arranged in the component supply space through the opening by the head unit. A step of retracting the head unit from the opening after completing the one mounting operation when receiving an instruction to remove the cart from the apparatus body during the operation. After confirming that the shutter is retracted from the opening, the shutter member may be moved to the opening to close the opening. In this case, the opening is not closed until the completion of one mounting operation, and the mounting operation can be performed efficiently. In addition, after the completion of one mounting operation, the shutter member moves to the opening after the head unit is retracted from the opening, so that interference between the head unit and the shutter member can be reliably prevented. .

  Further, the carriage replacement step includes a step of detecting closing of the opening portion by the shutter member, and a step of releasing the carriage clamp by detecting the closing of the opening portion and enabling the removal of the carriage. You may comprise, and by this, a trolley | bogie can be reliably extracted in the state by which the opening part was closed by the shutter member.

  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 while the carriage is exchanged by inserting and removing the carriage with respect to the apparatus main body, Components can be mounted. Therefore, the operation rate of the component mounting apparatus can be improved as compared with the conventional case.

  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. The component mounting apparatus 1 according to the first embodiment includes an apparatus main body 10 for mounting electronic components on a substrate P (FIG. 2) transported in a predetermined transport direction, and a tape feeder 31 (corresponding to a component supply unit of the present invention). And a collective exchanging carriage 20 that is inserted into and removed from the apparatus main body 10. 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 (substrate transfer, nozzle switching, etc.) related to the component mounting, and the apparatus main body. The tape feeder 31 is arranged by inserting the collective exchanging cart 20 with respect to 10 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, the component recognition camera 43 and the automatic nozzle changer 44 are juxtaposed in the substrate transport direction X. Moreover, it spreads on both sides of the width direction Y of the component recognition camera 43 and the automatic nozzle changer 44, and is divided into two spaces by the two cover units 50 on the (+ Y) direction side and two on the (−Y) direction side. Each of the spaces partitioned by the cover unit 50 functions as the component supply space 12. The batch exchange cart 20 can be inserted into and removed from the apparatus main body 1 at a position corresponding to each component supply space 12, and in this embodiment, up to four batch exchange carts 20 can be attached to the apparatus main body 10. It has become.

  FIG. 4 is a partial cross-sectional view of the collective exchanging carriage mounted on the apparatus main body. Each batch exchanging cart 20 can be mounted with a plurality of tape feeders 31 arranged side by side in a direction parallel to the substrate transport direction X (corresponding to the “arrangement direction” of the present invention). The component supply unit 30 is formed by the plurality of tape feeders 31 by being inserted. 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 cart 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 holds the handle portion 25 of the batch change cart 20 and moves it 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 at the component supply position 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 of (10 in this embodiment) mounting heads 451 arranged in the X direction, and the end of each tape feeder 31 on the side of the transport lane 41 by a nozzle at the tip of each mounting head 451. By picking up the components from the part, the components supplied by the component supply unit 30 are transferred to the substrate stopped at the stop position 42. 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.

  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 suction nozzle (not shown) is configured to be movable up and down. On the other hand, the nozzle rotation drive mechanism is a mechanism for rotating the suction nozzle as necessary, and can rotate the component to be positioned 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. This also applies to FIGS. 12 to 15 described later.

  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, a top plate 512 is fixed from the upper side portion of the first flat plate portion 511a of the side plates 511 and 511 to the side portion in the (−Y) direction, and the cover body 51 is secured by the side plates 511 and 511 and the top plate 512. Is configured.

  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.

  As shown in FIG. 7, when the shaft member 542 moves in the (−Y) direction, the shutter member 53 also moves in the (−Y) direction, and is positioned immediately above the opening 522 provided in the top cover 52. Then, the opening 522 is closed from above. 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 of the (−X) direction side support portion 531 is locked to the front stopper 541a and the shaft member 542 and the shutter member 53 are 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. During this movement, the pins 542a and 542c slide in the elongated holes 531a and 531c, respectively, to lower the shutter member 53. However, due to the action of the spring member 533, it is slightly later than the lowering timing of the top cover 52. It is configured to descend. 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 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 as 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. In addition, since the component supply space 12 is partitioned from the mounting space 11 inside the apparatus main body 10, the mounting related to the component mounting and the component mounting by the mounting unit 40 during the cart unclamping process and the cart clamping process are performed. Operations (substrate transfer, nozzle switching, etc.) are performed. Hereinafter, the cart unclamping process and the cart clamping process will be described with reference to the drawings.

  FIG. 8 is a flowchart showing the contents of the cart unclamping process executed by the component mounting apparatus shown in FIG. 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 can be executed. 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 trolley unclamping operation, a tape other than the tape feeder 31 that is the target of the trolley unclamping operation, that is, the tape mounted on the collective exchange trolley 20 in the insertion completion state with respect to the apparatus main body 10. Components supplied from the feeder 31 can be mounted on the substrate P. Moreover, preparation for component mounting processing after replacement, conveyance of the substrate P, and nozzle replacement can be performed in parallel with the cart unclamping operation.

  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.

  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 (when “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.

  FIG. 9 is a flowchart showing the contents of the cart clamping process executed by the component mounting apparatus shown in FIG. 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 to execute the cart clamping process. As in the case of the trolley unclamping process, the control unit 60 checks the operating state of the actuator in the mounting unit 40 in step S111. If the mounting unit 40 is in the ON state, the control unit 60 proceeds to step S113 as it is, and the trolley Start clamping operation. On the other hand, when the mounting unit 40 is in a stopped state (when “NO” in step S111), they are switched to the driving state (step S112), and then the process proceeds to the next step S113 to perform the carriage clamping operation. Run. Accordingly, in parallel with the cart clamping operation, the tape feeder 31 mounted on the collective exchange cart 20 in the insertion completed state with respect to the device main body 10 other than the tape feeder 31 that is the target of the cart clamping operation. Can be mounted on the board P. In addition, preparation for component mounting processing after replacement, conveyance of the substrate P, and nozzle replacement can be performed in parallel with the carriage clamping operation.

  In step S113, the control unit 60 displays a message prompting the insertion of the collective exchange cart 20 on the display unit 70, and in response to this, the operator inserts the collective exchanging cart 20 into the apparatus main body 10. 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. Confirm (step S114). 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 S115). On the other hand, when it is confirmed that the collective exchanging cart 20 has been inserted into a predetermined position of the apparatus main body 10 (“YES” in step S114), 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 S116). When the cart clamp switch is switched to the ON state, the control unit 60 clamps the batch exchanging cart 20 to the apparatus main body 10 by the clamp mechanism 13 (FIG. 3) (step S117).

  Here, when the carriage clamp cannot be confirmed (“NO” in step S118), the control unit 60 determines that a clamping failure has occurred, stops the error, and notifies the display unit 70 to that effect. It is displayed (step S119). On the other hand, when the cart clamp is confirmed (“YES” in step S118), the control unit 60 acquires the cart ID attached to the inserted batch exchanging cart 20 (step S120). 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 S121). When it is not the desired one (“NO” in step S121), the control unit 60 determines that a different cart has been inserted, stops the error, and displays that fact on the display unit 70 (step S122). .

  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 S123). As a result, the head unit 45 can access the tape feeder 31 mounted on the collective change cart 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 when the component is picked up by the tip portion (suction nozzle) of the mounting head 451 through the opening 522 and the picked-up component is taken out is shortened, and the time required for component mounting can be shortened. .

  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 unclamping process and the clamping process of the collective exchanging carriage 20 are performed. In addition, the component mounting operation to the board P is executed in the mounting space 11. Therefore, component mounting can be performed at a high operating rate. In addition, it is also possible to execute a preparatory process for performing component mounting after the setup change, for example, mounting related operations such as transport of the substrate P and nozzle replacement, between the collective change carts 20. Improvements can be made.

  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, as shown in FIGS. 5A and 7, the shutter member 53 moves in the direction away from the mounting space 11 where the components are mounted, that is, the (+ Y) direction to open the opening 522. . Here, the retracting direction of the shutter member 53 from the opening 522 is not particularly limited, but the tact time varies depending on the retracting direction. That is, in order to retract the shutter member 53 to the mounting space 11 side, it is necessary to provide a retracting area for the shutter member 53 on the mounting space 11 side of the opening 522, and the component supply position of the tape feeder 31 is mounted correspondingly. The moving distance of the head unit 45 is increased away from the space 11. As a result, the tact time increases. In contrast, in the first embodiment, since the retracting direction is set to the (+ Y) direction, there is no need to provide a retracting area on the mounting space 11 side of the opening 522, and the opening 522, the mounting space 11, and the like. The tact time can be effectively reduced.

  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.

  FIG. 10 is a flowchart showing the cart unclamping process in the second embodiment of the component mounting apparatus according to the present invention. The second embodiment differs greatly from the first embodiment in that the head unit 45 is to be replaced before the shutter member 53 is moved toward the opening 522 in the unclamping process of the batch exchanging carriage 20. It is the point which is made to evacuate from the collective exchanging cart 20 which is. Other configurations are basically the same as those of the first embodiment. Therefore, in the following, the same components are denoted by the same reference numerals and description thereof is omitted. Further, among the steps in the drawings, the same operation contents are described in parentheses, and detailed description thereof is omitted. These points are the same in other embodiments.

  In the second embodiment, when the operator operates the display unit 70 to give a trolley unclamp command to the control unit 60, the control unit 60 executes steps S201 and S202 in the driving state as in the first embodiment. The mounting unit 40 is maintained as it is, or the stopped mounting unit 40 is switched to the driving state, and then the cart unclamping operation is performed while the mounting unit 40 performs component mounting and mounting-related operations. In this cart unclamping operation, a message to the effect 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 waits for the operator to switch it to the OFF state (step S203). When the cart clamp switch is switched to the OFF state, the control unit 60 mounts the component supplied from the tape feeder 31 mounted on the collective exchange cart 20 to be replaced on the substrate P. First, the mounting of the component on the board P is interrupted, and the head unit 45 is retracted from the batch exchanging cart 20 (step S204). It should be noted that component mounting and other mounting-related operations using the other collective change cart 20 are continued.

  This evacuation operation is continued until the completion of evacuation is confirmed in step S205, and after confirmation of the completion of evacuation, steps S206 to S212 are executed as in the first embodiment. That is, the closing operation of the opening 522 by the shutter member 53, the releasing operation of the collective exchanging cart 20 by the clamp mechanism 13, and the extracting operation of the collective exchanging cart 20 are executed.

  As described above, according to the second embodiment of the present invention, before the shutter member 53 is moved to the opening 522 and the opening 522 is closed, the head unit 45 is retracted from the collective exchange cart 20 to be replaced. ing. Therefore, not only the same effect as the first embodiment can be obtained, but also the head unit 45 can be reliably prevented from interfering with the shutter member 53.

  FIG. 11 is a flowchart showing the cart unclamping process in the third embodiment of the component mounting apparatus according to the present invention. The third embodiment differs greatly from the second embodiment in that, in the second embodiment, the head unit 45 is retracted immediately when the cart clamp switch is switched to the OFF state. The head unit 45 is retracted after the work is completed. This “head operation” means an operation of mounting components supplied from the tape feeder 31 on the substrate P by the head unit 45. A tape feeder 31 mounted on the collective exchange cart 20 to be replaced may be included as a supplier of parts necessary for the head work currently in progress. In this case, it is possible to avoid interrupting the head operation on the substrate P in the middle by waiting for at least the completion of component supply from the tape feeder 31. Therefore, in the third embodiment, the component supply from the tape feeder 31 is completed prior to the retreat of the head unit 45 as described below. Other configurations and operations are basically the same as those in the second embodiment.

  In the third embodiment, when the operator operates the display unit 70 to give a trolley unclamp command to the control unit 60, the control unit 60 performs steps S301 and S302 in the same manner as in the first and second embodiments. Execute and maintain the mounting unit 40 in the driving state as it is, or after switching the mounting unit 40 in the stopped state to the driving state, execute the truck unclamping operation while performing the component mounting and the mounting-related operation by the mounting unit 40 To do. In this cart unclamping operation, 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 waiting for the operator to switch to the OFF state (step S303). When the carriage clamp switch is switched to the OFF state, the control unit 60 performs the head operation for mounting the components supplied from the tape feeder 31 attached to the batch exchange carriage 20 to be exchanged on the substrate P. It is determined whether or not the tact currently in progress remains (step S304). The control unit 60 continues the head operation (step S305) while determining that it remains (“YES” in step S304).

  On the other hand, when the head operation is completed, steps S306 to S314 are executed as in the second embodiment. That is, the retracting operation of the head unit 45 from the collective exchanging cart 20, the closing operation of the opening 522 by the shutter member 53, the releasing operation of the collective exchanging cart 20 by the clamp mechanism 13, and the extracting operation of the collective exchanging cart 20 are executed. To do.

  As described above, according to the third embodiment of the present invention, the head unit 45 is supplied from the tape feeder 31 attached to the collective exchange cart 20 before the head unit 45 is retracted from the collective exchange cart 20 to be exchanged. After completing the head operation for mounting the components on the substrate P, the head unit 45 is retracted from the batch exchanging carriage 20. Therefore, not only the same effects as those in the first embodiment and the second embodiment can be obtained, but also the working efficiency can be increased by preventing the interruption of the head work.

  Incidentally, in the above embodiment, as shown in FIG. 5A and FIG. 7, the shutter member 53 moves in the (+ Y) direction away from the mounting space 11 where the components are mounted and opens the opening 522. The shutter member 53 may be moved to the side to open the opening 522 (fourth embodiment to seventh embodiment).

  FIG. 12 is a diagram schematically showing the opening / closing operation of the opening in the fourth embodiment of the component mounting apparatus according to the present invention. In addition, the solid line arrow in the same figure shows the operation | movement order at the time of opening the opening part 522, and the broken line arrow has shown the operation | movement order at the time of closing the opening part 522. This also applies to FIGS. 13 to 15 described later.

Although not shown in the drawings, each shutter drive mechanism 56 has a drive cylinder and a cam mechanism as in the first embodiment, and the expansion and contraction movement of the piston portion of the drive cylinder is caused by the cam mechanism. The opening 522 is opened and closed by being converted into a sliding motion in the direction. That is, when opening the opening 522, the shutter member 53 slides in the (−Y) direction from the state in which the opening 522 is closed by the shutter member 53 (the state (a) in FIG. 12). It is located on the (−Y) direction side of the opening 522 via the b) state and the (c) state (state (d) in FIG. 12).

Although not shown in the drawings, each shutter drive mechanism 57 has a drive cylinder and a cam mechanism as in the first embodiment, and the expansion and contraction movement of the piston portion of the drive cylinder is caused by the cam mechanism. The opening 522 is opened and closed by being converted into a sliding motion in the direction and a rotational motion about the rotational axis AX extending in the X direction. That is, when opening the opening 522, the shutter member 53 slides in the (−Y) direction from the state where the opening 522 is closed by the shutter member 53 (the state (a) in FIG. 13) ((− in FIG. 13). b) State). Subsequently, the shutter member 53 rotates about the rotation axis AX, and the shutter member 53 rotates about 90 ° clockwise through the states (c) and (d) of FIG. (State (d) in FIG. 13). On the contrary, when closing the opening 522, an operation opposite to the above is performed, and the state from the state (e) in FIG. 13 to the state (d), (c) and (b) in FIG. Returning to the state of FIG.

  FIG. 14 is a diagram schematically showing the opening / closing operation of the opening in the sixth embodiment of the component mounting apparatus according to the present invention. In the sixth embodiment, as shown in FIG. 14, two shutter members 53A and 53B and a shutter drive mechanism 58 for driving the shutter members 53A and 53B are provided. The shutter drive mechanism 58 is attached to each side plate 511 as in the first embodiment. Although not shown in the drawings, each shutter drive mechanism 58 has a drive cylinder and a cam mechanism as in the first embodiment, and the expansion and contraction movement of the piston portion of the drive cylinder is caused by the cam mechanism so that the Y of the shutter member 53B. The opening 522 is opened and closed by being converted into a sliding motion in the direction. The shutter member 53A is connected to the shutter member 53B and is configured to rotate in conjunction with the sliding movement of the shutter member 53B.

  When opening the opening 522, the shutter member 53B slides in the (−Y) direction from the state in which the opening 522 is closed by the shutter member 53B (the state (a) in FIG. 14) and interlocks with the slide. Then, the shutter member 53A is rotated (state (b) in FIG. 14). Further, when the shutter member 53B slides in the (−Y) direction, the shutter member 53B is positioned on the (−Y) direction side of the opening 522 via the (c) state, the (d) state, and the (e) state of FIG. At the same time, the shutter member 53A rotates, and most of the shutter member 53A overlaps the shutter member 53B in a side view from the X direction (state (f) in FIG. 14). On the contrary, when closing the opening 522, an operation opposite to the above is performed, and the state (e), (d), (c), and (b) of FIG. ) Returns to the state (a) of FIG.

  FIG. 15 is a diagram schematically showing the opening / closing operation of the opening in the seventh embodiment of the component mounting apparatus according to the present invention. The seventh embodiment differs greatly from the sixth embodiment in that the shutter member 53A is stationary while the shutter member 53B is slidable with respect to the shutter member 53A and the top cover 52. It is. In the sixth embodiment, when opening the opening 522, the shutter member 53B slides in the (−Y) direction from the state where the opening 522 is closed by the shutter member 53B (the state (a) in FIG. 15).
