[0003] [Patent Document 1] JP 2022-130833 A Summary of the Invention [Problem to be solved by the invention]
[0004] Incidentally, the carrier tape is fed out when the component mounting device and the tape cassette supplying device are positioned, but a certain amount of positional deviation may occur due to individual differences between the devices, etc. In this case, the carrier tape in the tape cassette held by the holding unit may be deviated from the target position of the carrier tape in the component mounting device, and the carrier tape may not be accurately supplied.
[0005] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to improve the performance of supplying a carrier tape to a component mounting device. [Means for solving the problem]
[0006] (1) A tape cassette supplying device according to one embodiment of the present invention is a tape cassette supplying device that supplies a tape cassette containing a carrier tape to a component mounting device that holds a feeder that transports a carrier tape, and includes a holding unit that holds the tape cassette, a position acquisition unit that acquires position information regarding a contact position when the tape cassette held by the holding unit or the holding unit contacts the component mounting device, and an insertion position correction unit that corrects a first target insertion position for inserting the carrier tape into a tape insertion port in the feeder through which the carrier tape is inserted, based on the position information and a reference position of the feeder.
[0007] A component mounting system according to one embodiment of the present invention is a component mounting system comprising a component mounting device that holds a feeder that transports a carrier tape, and a tape cassette supplying device that supplies a tape cassette in which the carrier tape is stored, wherein the tape cassette supplying device comprises a holding section that holds the tape cassette, a position acquisition section that acquires position information regarding a contact position when the tape cassette or the holding section held by the holding section comes into contact with the component mounting device, and an insertion position correction section that corrects a first target insertion position for inserting the carrier tape into a tape insertion port in the feeder through which the carrier tape is inserted, based on the position information and a reference position of the feeder.
[0008] A tape cassette supplying method according to one embodiment of the present invention is a tape cassette supplying method in which a tape cassette containing a carrier tape is supplied by a tape cassette supplying device to a component mounting device that holds a feeder that transports the carrier tape, the tape cassette supplying device having a holding section that holds the tape cassette, and the tape cassette supplying method acquires position information regarding a contact position when the tape cassette held by the holding section or the holding section comes into contact with the component mounting device, and then corrects a first target insertion position for inserting the carrier tape into a tape insertion port in the feeder through which the carrier tape is inserted, based on the position information and a reference position of the feeder.
[0009] According to these, after acquiring position information on the contact position when the tape cassette held by the holding unit or the holding unit contacts the component mounting device, the first target insertion position is corrected based on the position information and the reference position of the feeder. In other words, even if the actual feeder is misaligned from the reference position, the first target insertion position can be corrected taking into account this misalignment. Since the carrier tape is guided based on the corrected first target insertion position, the carrier tape can be aligned even with respect to a misaligned tape insertion port. Therefore, the supply performance of the carrier tape to the feeder can be improved.
[0010] (2) In the tape cassette supplying device described in (1) above, when the position acquisition unit acquires the position information regarding the contact position when the tape cassette held by the holding unit or the holding unit comes into contact with the feeder, the insertion position correction unit may calculate the difference between the position information and a reference position of the feeder and add the difference to the first target insertion position, thereby correcting the first target insertion position.
[0011] According to this, when the position acquisition unit acquires position information relating to the contact position when the tape cassette or the holder contacts the feeder, the insertion position correction unit calculates the difference between the position information and the reference position of the feeder, and adds the difference to the first target insertion position. In other words, since the first target insertion position is corrected based on the difference between the current position information of the feeder and the reference position, the correction can be made more accurately.
[0012] (3) In the tape cassette supplying device described in (1) above, the component mounting device may include a cart supporting at least one of the feeders and a pair of abutment members arranged to sandwich the at least one feeder, and the position acquisition unit may acquire the position information when the tape cassette held by the holding unit or the holding unit comes into contact with each of the abutment members.
[0013] According to this, the position acquisition unit acquires position information when the tape cassette held by the holding unit or the holding unit contacts each of the abutment members provided on the dolly. In other words, even if the tape cassette is not directly contacted with the feeder, the first target insertion position can be corrected based on the position information obtained by contacting the abutment member. This makes it possible to reduce the load on the feeder that is applied by contacting the feeder.
[0014] (4) In the tape cassette supplying device described in (3) above, the insertion position correction unit may calculate a position of the feeder that is to be subjected to correction of the first target insertion position based on the position information when it contacts each of the abutment members, calculate a difference between the calculated position of the feeder and a reference position of the feeder, and add the difference to the first target insertion position, thereby correcting the first target insertion position.
[0015] According to this, the position information of the feeder for which the first target insertion position is to be corrected is calculated based on the position information when each of the abutment members is contacted, so that the current position information of the feeder can be obtained and the first target insertion position can be corrected without directly contacting the feeder. Also, when the dolly supports multiple feeders, it is not necessary to directly contact each feeder with the tape cassette held by the holding part or the holding part, so that the correction process of the first target insertion position of each feeder can be simplified.
[0016] (5) In the tape cassette supplying device described in (2) above, the tape cassette or the holding unit may have a tape feed unit that feeds the tip of the carrier tape contained in the tape cassette to the feeder, and the position acquisition unit may acquire the position information regarding the position of the feeder when the tape feed unit contacts the feeder.
[0017] According to this, the position acquisition unit acquires position information regarding the position of the feeder when the tape feed unit contacts the feeder. Here, the tape feed unit is a part that feeds the carrier tape to the tape insertion port. For this reason, it is easy to bring the tape feed unit into contact with the vicinity of the tape insertion port. If the position information can be acquired by bringing the tape feed unit into contact with the vicinity of the tape insertion port, the accuracy of correction of the first target insertion position can also be improved.
[0018] (6) In the tape cassette supplying device described in (5) above, the tape feed unit may have a positioning unit that is positioned relative to the feeder, and the position acquisition unit may acquire the position information of the feeder when the positioning unit is positioned relative to the feeder.
[0019] According to this, the position acquisition unit acquires the position information while the tape feed unit is positioned relative to the feeder by the positioning unit, so that the position information can be acquired stably. Therefore, the position information is less likely to vary, and as a result, the accuracy of the correction can be improved.
[0020] (7) In the tape cassette supplying device described in (6) above, the position acquisition unit may acquire the position information after the tape feed unit has come into contact with the feeder and the positioning unit is positioned on the feeder.
[0021] According to this, the position acquisition unit acquires the position information in a state where the positioning unit is positioned on the feeder after the tape feeding unit contacts the feeder, so that the position information can be acquired after vibrations immediately after contact have been alleviated. Therefore, the influence of vibrations on the position information can be suppressed, and as a result, the accuracy of correction can be improved.
[0022] (8) The tape cassette supplying device described in (6) or (7) above may further include a moving mechanism for moving the holding portion, and when positioning the positioning portion relative to the feeder, the moving mechanism may perform the positioning while moving the holding portion in a direction that reduces a reaction force generated when the positioning portion comes into contact with the feeder.
[0023] According to this, since positioning is performed while the movement mechanism reduces the reaction force against the holding portion, the stability of positioning can be improved.
[0024] (9) In the tape cassette supplying device described in any one of (1) to (8) above, the position acquisition unit may acquire the position information regarding the position of the feeder when the holding unit, not holding the tape cassette, comes into contact with the feeder.
[0025] According to this, even when the holding unit is not holding a tape cassette, the position information acquisition unit can acquire the position information. As a result, for example, when the holding unit is holding only a carrier tape, the first target insertion position can be corrected. In addition, the acquired position information regarding the feeder position can be used to correct the target position of the holding unit when the holding unit retrieves an empty tape cassette.
[0026] (10) In the tape cassette supplying device described in any one of (1) to (9) above, the position acquisition unit may acquire the position information every time the tape cassette supplying device is connected to the component mounting device.
[0027] According to this, since the position information is obtained every time the tape cassette supplying device is connected to the component mounting device, the first target insertion position can be corrected each time, and therefore the accuracy of the correction of the first target insertion position can be maintained.
[0028] (11) In the tape cassette supplying device described in any one of (1) to (10) above, the component mounting device may have a plurality of the feeders, and the position acquisition unit may acquire the position information for each of the plurality of feeders relative to a position of the feeder.
[0029] According to this, since the position information of each of the plurality of feeders is acquired, the first target insertion position for each feeder can be corrected, and therefore the supply performance of the carrier tape for each feeder can be improved.
[0030] (12) In the tape cassette supplying device described in any one of (1) to (11) above, the component mounting device may have a first feeder and a second feeder as the feeders, the position acquisition unit may acquire first feeder position information which is the position information regarding the position of the first feeder, and the insertion position correction unit may correct a second target insertion position for inserting the carrier tape into the tape insertion port of the second feeder based on the first feeder position information and a reference position of the first feeder.
[0031] According to this, the second target insertion position of the second feeder is corrected based on the first feeder position information and the reference position of the first feeder. In other words, when correcting the second target insertion position, the first feeder position information and the first feeder reference position are used, so it is possible to omit obtaining the position information of the second feeder. Therefore, the correction process can be simplified.
[0032] (13) In the tape cassette supplying device described in any one of (1) to (12) above, the component mounting device may have a tape cassette supporting unit that supports the tape cassette, and the insertion position correction unit may correct at least one of a target holding position at which the holding unit holds the tape cassette supported by the tape cassette support unit and a target installation position at which the holding unit installs the tape cassette on the tape cassette support unit based on the position information and a reference position of the feeder.
[0033] According to this, at least one of the target holding position and the target installation position is corrected based on the position information and the reference position of the feeder. In other words, when at least one of the target holding position and the target installation position is corrected, the position information and the reference position of the feeder are used, so that it is possible to simplify the correction process of at least one of the target holding position and the target installation position. Effect of the Invention
[0034] According to the present invention, the performance of supplying the carrier tape to the component mounting device can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0036] Hereinafter, a component mounting system according to an embodiment and its modified example of the present invention will be described with reference to the drawings. Note that the embodiment and its modified example described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components shown in the following embodiment and its modified example are only examples and are not intended to limit the present invention. In addition, each figure is a schematic diagram, and the dimensions are not necessarily illustrated precisely. Furthermore, in each figure, the same or similar components are given the same reference numerals. In the following description, the X-axis direction is the width direction of each device (component mounting device 20 and tape cassette supply device 40) provided in the component mounting system 10, the Y-axis direction is the arrangement direction of each device, and the Z-axis direction is the height direction (vertical direction) of each device. The Y-axis direction is also the connection direction of the dolly 30 to the component mounting device 20.
[0037] Furthermore, expressions indicating relative directions or attitudes, such as parallel and perpendicular, also include cases where the directions or attitudes are not strictly the same. For example, two directions being parallel does not only mean that the two directions are completely parallel, but also means that the two directions are substantially parallel, that is, that there is a difference of, for example, about a few percent. Furthermore, simply saying "X-axis direction" means both directions or either one of the directions parallel to the X-axis. The same applies to terms related to the Y-axis and Z-axis.
[0038] (Embodiment 1) Fig. 1 is an explanatory diagram showing a schematic configuration of a component mounting system 10 according to embodiment 1. As shown in Fig. 1, the component mounting system 10 according to embodiment 1 includes a component mounting device 20 and a tape cassette supplying device 40. The component mounting system 10 is an example of a supplying system.
[0039] The component mounting device 20 is a device that mounts components supplied by a component supply unit 31 provided on a cart 30 onto a board 50. The component mounting device 20 is an example of a working device that performs work on the board 50. Specifically, the component mounting device 20 includes a component mounting device main body 20a and a cart 30. The component mounting device main body 20a includes a head 21 that picks up components 87 (see FIG. 5) on the component supply unit 31 of the cart 30 and transfers and mounts them onto the board 50, a board transport section 22 that transports the board 50 on which the components 87 have been mounted by the head 21 to a downstream reflow device (not shown), and a positioning device 23 that positions the cart 30.
[0040] The cart 30 is a cart that is connected to the component mounting device main body 20a by being positioned by the positioning device 23. The cart 30 includes a component supply unit 31 that draws in a carrier tape 83 (see FIG. 5) that stores components 87 and supplies the components 87, and a first tape cassette support section 70 (see FIG. 2, etc.) that detachably holds a plurality of tape cassettes 60 that store rolls 80 of the carrier tape 83.
[0041] The tape cassette supplying device 40 is an example of a supplying device that supplies a tape cassette 60 to the first tape cassette support portion 70 of the dolly 30 and retrieves an empty tape cassette 60 from the first tape cassette support portion 70. In other words, the tape cassette 60 is an example of a member that is supplied to the supplying device.
[0042] [Trolley] Next, the dolly 30 will be described in detail. Fig. 2 is a plan view showing the dolly 30 and the positioning device 23 according to the first embodiment. Fig. 2 shows a state in which the dolly 30 is separated from the positioning device 23. Fig. 3 is a perspective view showing the dolly 30 according to the first embodiment. Fig. 4 is an explanatory diagram showing a state in which a first tape cassette 61, which is an example of a tape cassette 60, and a second tape cassette 65, which is an example of a tape cassette 60, have been removed from the dolly 30 according to the first embodiment. Fig. 4 shows a state in which both the first receiving device 38 and the second receiving device 39 provided on the dolly 30 have been removed.
[0043] As shown in FIGS. 2 to 4, the carriage 30 has a component supply unit 31, a plurality of first tape cassette support parts 70, and a carriage body 32 that supports them. The first tape cassette support part 70 is an example of a tape cassette support part. The component supply unit 31 has a plurality of feeders 311 (component supply devices) that are arranged in the X-axis direction so as to be paired with each of the first tape cassette support parts 70. In FIG. 3, only the feeders 311 at both ends in the X-axis direction are illustrated. Each feeder 311 pulls out the carrier tape 83 from the tape cassette 60 (the first tape cassette 61 or the second tape cassette 65) held by the corresponding first tape cassette support part 70, and transports the components stored in the carrier tape 83 to a pick-up position by the head 21.
[0044] The cart body 32 has a base 300 and a plurality of casters 33 attached to the underside of the base 300, and the casters 33 allow the cart body 32 to be freely movable on the floor surface.
[0045] On the pedestal 300, the component supply unit 31 is disposed in the positive direction of the Y axis, and a plurality of first tape cassette support parts 70 are disposed in an array in the X axis direction in the negative direction of the Y axis. For example, a pair of holding walls 34 are erected in the positive direction of the Y axis on the pedestal 300. A unit holding part 312 for holding the component supply unit 31 is provided on the pair of holding walls 34 so as to be capable of rising and lowering. Positioning rollers 313 for positioning each of the holding walls 34 with respect to the positioning device 23 are provided on both ends of the unit holding part 312 in the X axis direction.
[0046] On base 300, in the negative Y-axis direction, there are provided support base 35 and height adjustment unit 36 (described later: see FIG. 8) that connects support base 35 and base 300 and adjusts the height position of support base 35.
[0047] The support base 35 is a portion that supports a plurality of first tape cassette support parts 70. A pair of support pillars 351, 352 arranged in the Y-axis direction are provided at both ends of the support base 35 in the X-axis direction. A first roller 353 that is positioned relative to the positioning device 23 is provided at the upper end of the support pillar 351 in the positive Y-axis direction. A second roller 354 that is positioned relative to the positioning device 23 is provided at the upper end of the support pillar 352 in the negative Y-axis direction. The first roller 353 and the second roller 354 are aligned along the connection direction (Y-axis direction) of the carriage 30 to the component mounting device 20, and the first roller 353 is disposed at a higher position than the second roller 354.
[0048] The multiple first tape cassette support parts 70 supported by the support base 35 are each configured to detachably hold a first tape cassette 61 or a second tape cassette 65. Similarly, each first tape cassette support part 70 is configured to detachably hold a first receiving device 38 or a second receiving device 39. For example, when the first tape cassette 61 is attached to a specific first tape cassette support part 70, the first receiving device 38 is attached to that first tape cassette support part 70. At this time, in the specific first tape cassette support part 70, the first tape cassette 61 is disposed in the negative direction of the Y axis, and the first receiving device 38 is disposed in the positive direction of the Y axis.
[0049] On the other hand, when the second tape cassette 65 is attached to a given first tape cassette support portion 70, the second receiving device 39 is attached to that first tape cassette support portion 70. At this time, in the given first tape cassette support portion 70, the second tape cassette 65 is disposed in the negative direction of the Y axis, and the second receiving device 39 is disposed in the positive direction of the Y axis.
[0050] [Carrier tape] Fig. 5 is a perspective view showing a schematic configuration of carrier tape 83 constituting roll body 80 according to the first embodiment. As shown in Fig. 5, carrier tape 83 has tape body 85 having a plurality of component pockets 84, and cover tape 86 attached to tape body 85 and covering each of component pockets 84. Components 87 are stored in component pockets 84. A plurality of feed holes 88 that engage with sprockets of feeder 311 are formed in tape body 85 at positions exposed from cover tape 86. This carrier tape 83 is wound to form roll body 80 (see Fig. 6, etc.).
[0051] [Tape cassette] Next, the tape cassette 60 will be described in detail with reference to FIGS. 6 and 7. The first tape cassette 61 and the second tape cassette 65, which are examples of the tape cassette 60, are different types of tape cassettes. Specifically, the first tape cassette 61, which is a first type, and the second tape cassette 65, which is a second type, differ in that they store roll bodies 80 of different sizes. For example, the first tape cassette 61 is configured to store a roll body 80 larger than that of the second tape cassette 65. Therefore, the first tape cassette 61 itself is also larger than the second tape cassette 65. The size of the roll body 80 differs depending on the type of components stored in the carrier tape 83. Hereinafter, the roll body 80 stored in the first tape cassette 61 will be referred to as the first roll body 81, and the roll body 80 stored in the second tape cassette 65 will be referred to as the second roll body 82.
[0052] First, the first tape cassette 61 will be described as an example of the tape cassette 60. Fig. 6 is an exploded perspective view in which a part of the first tape cassette 61 according to the first embodiment is disassembled. As shown in Fig. 6, the first tape cassette 61 includes a first storage section 62, a first tape feed section 93, and a first slide support section 94. The first tape feed section 93 is a section that feeds out the leading end of the carrier tape 83 to the component supply unit 31. The first slide support section 94 is a section that supports the first tape feed section 93 so that it can slide freely in the Y-axis direction.
[0053] The first tape cassette 61 has a flat outer shape with its thickness direction in the X-axis direction. In the first tape cassette 61, an upper surface 611 is formed parallel to the XY plane, and a base end surface 612 in the negative Y-axis direction is formed parallel to the XZ plane. An identification shape 611a for identifying the type of tape cassette 60 is formed on the upper surface 611. Specifically, the identification shape 611a is a notch formed on the upper surface 611, and is disposed at a distance D1 from the end of the upper surface 611 in the negative Y-axis direction.
[0054] The first storage section 62 has a first storage space H1 (storage space) that stores the first roll body 81. Specifically, the first storage section 62 has a first frame body 621 and a pair of first cover bodies 622, which form the first storage space H1.
[0055] The first frame body 621 is a substantially U-shaped frame that is open in the Y-axis positive direction when viewed in the X-axis direction. The pair of first cover bodies 622 are formed in a flat plate shape and are attached to the first frame body 621 so as to sandwich the first frame body 621 in the X-axis direction. As a result, each of the first cover bodies 622 covers the recess of the first frame body 621 in the X-axis direction. The recess of the first frame body 621 and the pair of first cover bodies 622 form a first storage space H1. When an unused first roll body 81 is stored in the first storage space H1, the pair of first cover bodies 622 covers the entire first roll body 81. The first storage space H1 is open in the Y-axis positive direction. That is, an opening 623 is provided at the end of the first storage section 62 close to the component supply unit 31. This opening 623 allows the first roll body 81 to move forward and backward along the Y-axis direction relative to the first storage space H1. A drop prevention portion 624 for preventing the first roll body 81 from dropping out of the opening 623 is provided at the lower end of the first frame body 621 .
[0056] A gripped portion 625 is provided above the first frame body 621 via a first tape feeding portion 93 and a first slide support portion 94 .
[0057] A pair of leaf springs 621a, 621b for restricting movement of the first slide support portion 94 is attached to the upper portion of the first frame body 621. The pair of leaf springs 621a, 621b are arranged along the Y-axis direction, and their ends in the positive direction of the Y-axis protrude upward.
[0058] The gripped portion 625 is a portion that is gripped by the tape cassette supplying device 40. That is, when the first tape cassette 61 is supplied to the first tape cassette support portion 70 by the tape cassette supplying device 40 or when the first tape cassette 61 is removed from the first tape cassette support portion 70, the gripped portion 625 is gripped by the holding portion 43 (see FIG. 14 and the like) of the tape cassette supplying device 40. The gripped portion 625 has an L-shaped notch formed on both sides in the Y-axis direction, and the holding portion 43 of the tape cassette supplying device 40 is inserted into the notch. A tag 626 that stores various information is provided on the upper surface of the gripped portion 625. The information stored in the tag 626 includes information about the components 87 stored in the carrier tape 83 that constitutes the first roll body 81 or information about the first tape cassette 61. The information about the components 87 includes the type, size, and the like of the components 87. The information about the first tape cassette 61 includes the type, size, and the like of the first tape cassette 61. The tag 626 is designed so that information can be read by a reading unit 437 (see FIG. 15 and the like) provided in the holder 43.
[0059] Next, the second tape cassette 65 will be described as an example of the tape cassette 60. Fig. 7 is an exploded perspective view of a portion of the second tape cassette 65 according to the first embodiment. As shown in Fig. 7, the second tape cassette 65 includes a second storage section 66, a second tape feed section 293, and a second slide support section 294. The second tape feed section 293 is a section that feeds out the leading end of the carrier tape 83 to the component supply unit 31. The second slide support section 294 is a section that supports the first tape feed section 93 so that it can slide freely in the Y-axis direction.
[0060] The second tape cassette 65 has a flat outer shape with the thickness direction being in the X-axis direction. In the second tape cassette 65, an upper surface 651 is formed parallel to the XY plane, and a base end surface 652 in the negative Y-axis direction is formed parallel to the XZ plane. In addition, an identification shape 651a for identifying the type of the tape cassette 60 is formed on the upper surface 651. Specifically, the identification shape 651a is a notch formed on the upper surface 651, and is disposed at a distance D2 from the end of the upper surface 651 in the negative Y-axis direction. The distance D2 is smaller than the distance D1. In other words, the identification shape 651a of the second tape cassette 65 is disposed at a different position from the identification shape 611a of the first tape cassette 61. Therefore, by detecting the positions of the identification shapes 611a and 651a, it is possible to identify the type of the tape cassette to be detected.
[0061] The second tape cassette 65 differs from the first tape cassette 61 in that the second storage section 66 is smaller than the first storage section 62, but the basic structure is generally the same. For this reason, only the parts of the second tape cassette 65 that are different from the first tape cassette 61 will be described here, and the other parts will be given the same reference numerals as the first tape cassette 61 and will follow the description therefor. For example, the gripped portion 625 of the first tape cassette 61 and the second tape cassette 65 have the same structure. For this reason, the distance from the base end faces 612, 652 to the gripped portion 625 of the first tape cassette 61 and the second tape cassette 65 is the same.
[0062] The second storage section 66 has a second frame body 661 and a pair of second cover bodies 662 which form a second storage space H2 (storage space) for storing the second roll body 82. The second storage space H2 is smaller than the first storage space H1. When an unused second roll body 82 is stored in the second storage space H2, the pair of second cover bodies 662 entirely cover the second roll body 82. An opening 663 of the second storage section 66 allows the second roll body 82 to freely advance and retreat along the Y-axis direction relative to the second storage space H2.
[0063] A pair of recesses 611b, 651b are formed on the top surfaces 611, 651 of the first tape cassette 61 and the second tape cassette 65 at positions that sandwich the gripped portion 625. These recesses 611b, 651b are used for positioning the first tape cassette 61 and the second tape cassette 65 when they are held by the holding portion 43, and details of these will be described later.
[0064] [First receiving device and second receiving device] Next, the first receiving device 38 and the second receiving device 39 will be described. As shown in Figs. 3 and 4, the first receiving device 38 is disposed in the Y-axis plus direction of the first tape cassette 61 held by the first tape cassette support portion 70. The first receiving device 38 is a device that receives the first roll body 81 moved from the first tape cassette 61. The first receiving device 38 has a flat outer shape with the X-axis direction as the thickness direction. An engagement piece 382 that is engaged with a support shaft 321 that is provided on the dolly body 32 and is parallel to the X-axis direction is provided on the upper part of the first receiving device 38. An opening 381 is formed at the end of the first receiving device 38 in the Y-axis minus direction, and the first receiving device 38 receives the first roll body 81 from this opening 381.
[0065] The second receiving device 39 is disposed in the positive direction of the Y axis of the second tape cassette 65 held by the first tape cassette support portion 70. The second receiving device 39 is a device that receives the second roll body 82 moved from the second tape cassette 65. The second receiving device 39 has a flat outer shape with its thickness direction in the X axis direction. A locking piece 392 that is locked to the support shaft 321 of the cart main body 32 is provided on the upper part of the second receiving device 39. An opening 391 is formed at the end of the second receiving device 39 in the negative direction of the Y axis, and the second receiving device 39 receives the second roll body 82 from this opening 391.
[0066] [First tape cassette support part] Next, the first tape cassette support portion 70 will be described. Fig. 8 is a plan view showing the first tape cassette support portion 70 according to the first embodiment. Figs. 9A to 9C are plan views showing the operation of the first tape cassette support portion 70 according to the first embodiment. Fig. 9A shows a first posture in which the first tape cassette support portion 70 holds the first tape cassette 61 at a first position. Figs. 8 and 9C show a second posture in which the first tape cassette support portion 70 holds the second tape cassette 65 at a second position. Fig. 9B shows a state in which the first tape cassette support portion 70 is in the middle of moving between the first posture and the second posture.
[0067] As shown in FIGS. 8 to 9C, the first tape cassette support portion 70 has a slot 71, a pair of legs 72, and a beam portion 73.
[0068] The slot 71 is a portion into which the first tape cassette 61 or the second tape cassette 65 is inserted, and is supported by a pair of legs 72. The slot 71 is formed like a rail with an open upper portion, and the first tape cassette 61 or the second tape cassette 65 is inserted and placed in this open portion.
[0069] A fixing portion 711 that protrudes upward is provided at the end of the slot 71 in the negative Y-axis direction. The fixing portion 711 is a portion that fixes the first tape cassette 61 or the second tape cassette 65 inserted into the slot 71.
[0070] The pair of legs 72 have an upper limb 721 and a lower limb 722. The end of the upper limb 721 in the positive direction of the Z axis rotatably supports the slot 71. The end of the lower limb 722 in the negative direction of the Z axis is rotatably supported by the support base 35. The end of the upper limb 721 in the negative direction of the Z axis and the end of the lower limb 722 in the positive direction of the Z axis are rotatably connected. In one leg 72 and the other leg 72, a beam portion 73 is rotatably connected to the connecting position of the upper limb 721 and the lower limb 722. In other words, the beam portion 73 is bridged between the pair of legs 72.
[0071] 9A , when the first tape cassette support part 70 is in the first position, the upper limbs 721 and lower limbs 722 of each leg part 72 are folded, and the slots 71 are lowered to the lowest position. In this first position, the first tape cassette 61 is placed in the slots 71 and fixed by the fixing parts 711. At this time, the first tape cassette 61 is held in the first position by the first tape cassette support part 70.
[0072] 9C , when the first tape cassette support part 70 is in the second position, the upper leg 721 and the lower leg 722 of each leg 72 are extended in a straight line, and the slot 71 is raised to the highest position. In this second position, the second tape cassette 65 is placed in the slot 71 and fixed by the fixing part 711. At this time, the second tape cassette 65 is held in the second position by the first tape cassette support part 70.
[0073] The switching between the first position and the second position is performed by extending and contracting each leg 72, as shown in Fig. 9B. Specifically, when switching from the first position to the second position, the switching is performed by extending each folded leg 72 (in the order of Figs. 9A, 9B, and 9C). When switching from the second position to the first position, the switching is performed by folding each extended leg 72 (in the order of Figs. 9C, 9B, and 9A).
[0074] [Height adjustment section] Next, the height adjustment unit 36 provided on the support base 35 will be described. As shown in Fig. 8, the height adjustment unit 36 is disposed between the base 300 and the support base 35, and adjusts the height position of the support base 35 relative to the base 300 by expanding and contracting in the Z-axis direction. In other words, the height adjustment unit 36 indirectly adjusts the height of the first tape cassette support portion 70 by adjusting the height of the support base 35. A pair of height adjustment units 36 are provided with a predetermined interval in the X-axis direction, but since the basic structure is similar, the height adjustment unit 36 in the positive direction of the X-axis will be described here.
[0075] Specifically, the height adjustment section 36 has a standing wall 361, a pair of first link members 362, a pair of second link members 363, and a beam portion 364. The standing wall 361 is a wall that rises from the upper surface of the base 300 and extends in the Y-axis direction. The pair of first link members 362 are arranged in the Y-axis direction, and each of the lower ends is rotatably connected to the standing wall 361. The pair of second link members 363 has each of its lower ends rotatably connected to the upper ends of the first link members 362, and each of its upper ends rotatably connected to the support base 35. The beam portion 364 is a beam that extends in the Y-axis direction, and is rotatably connected to a connecting position between each of the first link members 362 and each of the second link members 363. The first link members 362 and each of the second link members 363 are folded and extended, so that the height of the first tape cassette support section 70 on the support base 35 is also adjusted. That is, the height position of the first tape cassette support portion 70 and the component mounting device 20 is adjusted. When the dolly 30 is connected to the positioning device 23, the height adjustment portion 36 expands and contracts as it is guided by the positioning device 23, thereby adjusting the height position of the first tape cassette support portion 70.
[0076] [Transfer of roll body between tape cassette and receiving device] Next, the movement of the roll body 80 between the tape cassette 60 (the first tape cassette 61 or the second tape cassette 65) and the receiving device (the first receiving device 38 or the second receiving device 39) will be described. Here, the movement of the roll body 80 between the first tape cassette 61 and the first receiving device 38 is illustrated, but the movement between the second tape cassette 65 and the second receiving device 39 is generally similar.
[0077] 10A to 10C are explanatory diagrams showing the movement of the roll body 80 between the first tape cassette 61 and the first receiving device 38 according to the first embodiment. FIG. 10A shows a state in which the leading end of the carrier tape 83 constituting the roll body 80 stored in the first tape cassette 61 has begun to be fed out by the sprocket of the feeder 311. When the carrier tape 83 is gradually pulled out from the roll body 80 from this state, the roll body 80 moves toward the first receiving device 38 due to the propulsive force. FIG. 10B shows a state in which the roll body 80 is midway through its movement. When the roll body 80 moves further, the first receiving device 38 receives the roll body 80. FIG. 10C shows a state in which the roll body 80 has been received by the first receiving device 38.
[0078] In the feeder 311, a pair of sprockets are provided at a distance in the Y-axis direction at the tape insertion opening 320 into which the carrier tape 83 is inserted. One sprocket feeds the carrier tape 83 unwound from the roll body 80 in the first receiving device 38, and the other sprocket feeds the carrier tape 83 unwound from the roll body 80 in the first tape cassette 61. For this reason, when the roll body 80 remains in the first receiving device 38, one sprocket continues to feed the carrier tape 83 of the roll body 80, and when the roll body 80 is gone, the other sprocket feeds the carrier tape 83 of the roll body 80 in the first tape cassette 61. At this time, since the first receiving device 38 is empty, the roll body 80 in the first tape cassette 61 moves to the first receiving device 38 as shown in FIGS. 10A to 10C. In the first receiving device 38, the carrier tape 83 is stably fed from the roll body 80 to the feeder 311. That is, the inside of the first receiving device 38 is the feed position of the roll body 80 .
[0079] At this time, the first tape cassette 61 is empty. The empty first tape cassette 61 is removed by the tape cassette supplying device 40 and replaced with a new first tape cassette 61.
[0080] [Tape cassette supply device] Next, the tape cassette supplying device 40 will be described. Fig. 11 is a perspective view showing a schematic configuration of the tape cassette supplying device 40 according to the first embodiment. As shown in Fig. 11, the tape cassette supplying device 40 is a movable device that is transported on a floor surface by a transport vehicle 490, for example an AGV (Automatic Guided Vehicle), and is a device that supplies and collects tape cassettes 60 to and from component mounting devices 20. In other words, the tape cassette supplying device 40 is a device that moves between a plurality of component mounting devices 20 by the transport vehicle 490, and transfers the tape cassette 60 to each component mounting device 20.
[0081] 12 is an explanatory diagram showing a state before tape cassette supplying device 40 according to embodiment 1 is connected to component mounting device 20. Tape cassette supplying device 40 is transported by transport vehicle 490 and connected to an end portion in the negative Y-axis direction of positioning device 23, which is a part of component mounting device 20 (see FIG. 1). Therefore, in the connected state, tape cassette supplying device 40 and component mounting device 20 are arranged side by side in the Y-axis direction.
[0082] Fig. 13 is a top view showing a schematic internal structure of the tape cassette supplying device 40 and the component mounting device 20 according to the first embodiment when they are connected to each other. Fig. 13 shows a dolly 30 having 17 first tape cassette supporting portions 70 arranged in the X-axis direction (a so-called 17-series dolly). Therefore, a total of 17 first receiving devices 38 and / or second receiving devices 39 can be installed on the dolly 30, and a total of 17 first tape cassettes 61 and / or second tape cassettes 65 can also be installed on the dolly 30. It should be noted that dollies 30 of types other than the 17-series dolly (e.g., a 20-series dolly) can also be connected to the component mounting device main body 20a. Different types of dollies 30 have different lengths (widths) in the X-axis direction.
[0083] The tape cassette supplying device 40 has an open end on the positive direction of the Y axis, and a pair of connection guide parts 41 protruding in the positive direction of the Y axis are provided at this end. The connection guide parts 41 are members that guide the movement of the tape cassette supplying device 40 when the tape cassette supplying device 40 is connected to the positioning device 23. Specifically, the connection guide parts 41 have rollers that roll on the wall surface of the positioning device 23 to guide the movement of the tape cassette supplying device 40 when connected.
[0084] Each connection guide section 41 has a carriage position detection section 411 that detects the position of the carriage 30. Each carriage position detection section 411 is an optical length measurement sensor. Examples of the length measurement sensor include a laser type length measurement sensor and an LED type length measurement sensor. The carriage position detection section 411 is configured to measure the distance to the side of the carriage 30 in the connected state. Here, a carriage locating member 310 for detecting the position of the carriage 30 is provided on each outer side surface of the carriage 30 facing the X-axis positive direction or the X-axis negative direction. The carriage locating member 310 is a member that receives detection light from the carriage position detection section 411 and returns the reflected light to the carriage position detection section 411. In other words, the carriage position detection section 411 can detect the position of the carriage 30 by detecting the position of the carriage locating member 310. Furthermore, by using the detection result of the carriage position detection unit 411, the width of the carriage 30 can be specified, and therefore it is also possible to determine the type of carriage 30 (whether it is a 17-gantry carriage or a 20-gantry carriage).
[0085] Arranged inside the tape cassette supplying device 40 are a support section 42 that supports the tape cassette 60, a holding section 43 (see Figure 14, etc.) that holds the tape cassette 60 supported by the support section 42, and a support section moving mechanism 44 that moves the support section 42.
[0086] The support portion 42 has a plurality of second tape cassette support portions 421 which individually support each tape cassette 60, and a mounting base 422 on which the plurality of second tape cassette support portions 421 are mounted. Each second tape cassette support portion 421 is a slot extending in the Y-axis direction, and is arranged along the X-axis direction with respect to the mounting base 422. In the connected state, each second tape cassette support portion 421 faces each first tape cassette support portion 70 of the dolly 30 in the Y-axis direction. In other words, the Y-axis direction is an example of a facing direction.
[0087] [Holding part] As shown in Fig. 11, the holding unit 43 is disposed above the support unit 42. The holding unit 43 is moved by a moving mechanism 45 provided in the tape cassette supplying device 40. The moving mechanism 45 moves the holding unit 43 in the X-axis direction, the Y-axis direction, and the Z-axis direction, and rotates the holding unit 43 around the Z-axis direction. In cooperation with the moving mechanism 45, the holding unit 43 holds the tape cassette 60 supported by each second tape cassette support unit 421 and supplies it to the component mounting device 20. In addition, in cooperation with the moving mechanism 45, the holding unit 43 holds the tape cassette 60 supported by each first tape cassette support unit 70 of the component mounting device 20, moves it to the tape cassette supplying device 40, and collects it.
[0088] Fig. 14 is a perspective view showing a state in which the holding portion 43 according to embodiment 1 holds the tape cassette 60 (first tape cassette 61). Fig. 15 is a plan view showing a schematic configuration of the holding portion 43 according to embodiment 1.
[0089] As shown in Figures 14 and 15, the holding portion 43 has a holding main body portion 430, a pair of chuck portions 431, a driving portion 432, a pair of positioning portions 433, a first sensor 434, a second sensor 435, a third sensor 436, and a reading portion 437.
[0090] The holding main body 430 is connected to a moving mechanism 45, and is equipped with a pair of chuck portions 431, a drive portion 432, a pair of positioning portions 433, a first sensor 434, a second sensor 435, a third sensor 436, and a reading portion 437.
[0091] The pair of chuck portions 431 are attached to the lower portion of the holding body portion 430 and protrude downward from the lower end of the holding body portion 430. The pair of chuck portions 431 are arranged at an interval in the Y-axis direction, and the interval is variable. The lower end of each chuck portion 431 protrudes toward the other chuck portion 431. The protruding portions of each chuck portion 431 are arranged at positions that sandwich the gripped portion 625 of the tape cassette 60, and when the interval between each chuck portion 431 narrows, the gripped portion 625 is gripped. When the gripped portion 625 is gripped by each chuck portion 431, the tape cassette 60 is held by the holding portion 43.
[0092] The driving unit 432 is a device that moves the pair of chuck portions 431 in the Y-axis direction. For example, the driving unit 432 is a motor, a solenoid, etc. When the driving unit 432 moves the pair of chuck portions 431, the distance between the chuck portions 431 varies.
[0093] The pair of positioning portions 433 are disposed outside the pair of chuck portions 431, and are pins that protrude downward from the lower end surfaces of the corresponding portions. Each positioning portion 433 is biased downward by an elastic body (not shown). The lower end portion of each positioning portion 433 has a tapered shape. Each positioning portion 433 can be freely inserted into and removed from a recess (recess 611b or recess 651b: see FIG. 6 or FIG. 7) formed on the upper surface (upper surface 611 or upper surface 651: see FIG. 6 or FIG. 7) of the tape cassette 60. When each positioning portion 433 is incompletely inserted into the recess 611b, for example, it is pushed upward by the recess 611b against the biasing force.
[0094] The first sensor 434 is a sensor that detects whether or not a tape cassette 60 is present directly below the holding portion 43. The first sensor 434 is disposed in the negative Y-axis direction further from the positioning portion 433 in the negative Y-axis direction out of the pair of positioning portions 433. The first sensor 434 is an optical sensor that irradiates detection light downward and receives reflected light from an object (tape cassette 60) to detect the presence or absence of an object.
[0095] The second sensor 435 is a sensor that detects whether the positioning portion 433 is inserted into the recess 611b (or recess 651b) on the top surface of the tape cassette 60. The second sensor 435 is an optical sensor that detects the presence or absence of an object by irradiating detection light in a horizontal direction and receiving transmitted light. The second sensor 435 is disposed at a position corresponding to the base of the positioning portion 433 in the negative Y-axis direction of the pair of positioning portions 433. When the positioning portion 433 is not pressed by the recess 611b, the base of the positioning portion 433 is not disposed within the second sensor 435. In contrast, when the positioning portion 433 is pressed by the recess 611b and raised, the base of the positioning portion 433 is disposed within the second sensor 435. As a result, the base of the positioning portion 433 blocks the detection light of the second sensor 435, so that the second sensor 435 can detect that the positioning portion 433 is pressed by the recess 611b.
[0096] The third sensor 436 is a sensor that detects the type of the tape cassette 60 before it is held based on the identification shape (identification shape 611a or identification shape 651a: see FIG. 6 or FIG. 7). The third sensor 436 is disposed in the negative Y-axis direction from the second sensor 435. The third sensor 436 is disposed at a position corresponding to the identification shape 611a of the first tape cassette 61 held by the holding unit 43. The third sensor 436 is an optical sensor. When the third sensor 436 detects the identification shape 611a, it is possible to determine that the detection target is the first tape cassette 61. On the other hand, when the first sensor 434 detects an object and the third sensor 436 does not detect the identification shape 611a, it is possible to determine that the detection target is the second tape cassette 65.
[0097] The reading unit 437 is a tag reader that reads information from the tag 626 of the tape cassette 60. The reading unit 437 may have a function of writing information to the tag 626. The reading unit 437 is disposed between the pair of chuck units 431. Therefore, when the gripped portion 625 is gripped by the pair of chuck units 431, the tag 626 on the gripped portion 625 and the reading unit 437 face each other. In other words, the tag 626 of the tape cassette 60 held by the holding unit 43 is in a state in which information can be read by the reading unit 437.
[0098] [Support movement mechanism] 13, the support unit moving mechanism 44 is a uniaxial stage that moves the mounting base 422 of the support unit 42 in the X-axis direction, thereby moving each second tape cassette support unit 421 in the X-axis direction. In other words, the X-axis direction is an example of a second orthogonal direction that is orthogonal to the facing direction (Y-axis direction) in a horizontal plane that includes the facing direction in which the second tape cassette support unit 421 faces the first tape cassette support unit 70. The support unit moving mechanism 44 is able to align each second tape cassette support unit 421 with each first tape cassette support unit 70 of different types of dollies 30 by moving the second tape cassette support units 421 in the X-axis direction.
[0099] [Component mounting system control configuration] Next, a description will be given of the control configuration of the component mounting system 10. Fig. 16 is a block diagram showing the control configuration of the component mounting system 10 according to the first embodiment. As shown in Fig. 16, the component mounting system 10 has a component mounting device main body 20a, a dolly 30, a tape cassette supplying device 40, a transport vehicle 490, and a management computer 100, which are connected via a communication network, and the entire system is controlled by the management computer 100.
[0100] The component mounting device main body 20a includes a head 21, a board transport unit 22, a communication unit 201, and a control unit 202 that controls these. The communication unit 201 is a communication module for communicating with the management computer 100, the tape cassette supply device 40, the dolly 30, and the transport vehicle 490 wirelessly or by wire, and is communicatively connected to a communication network. The control unit 202 includes a CPU, RAM, and ROM, and the CPU loads a program in the ROM into the RAM and executes it to control each unit of the component mounting device main body 20a. The control unit 202 may also control each unit based on commands from the management computer 100.
[0101] The cart 30 includes each feeder 311, a communication unit 301, and a control unit 302 for controlling these. The communication unit 301 is a communication module for communicating with the management computer 100, the tape cassette supplying device 40, the component mounting device main body 20a, and the transport vehicle 490 by wireless or wired means, and is connected to a communication network for free communication. The control unit 302 includes a CPU, a RAM, and a ROM, and the CPU loads a program in the ROM into the RAM and executes it to control each part of the cart 30. The control unit 302 may control each part based on a command from the management computer 100. Each feeder 311 is provided with a trailing end detection unit 315 for detecting the trailing end of the carrier tape 83 being supplied. When the trailing end detection unit 315 detects the trailing end of the carrier tape 83, it is detected that the roll 80 in the receiving device is empty. Therefore, the feeder 311 winds up the carrier tape 83 of the next roll 80 from the tape cassette corresponding to the receiving device, and moves the next roll 80 to the receiving device.
[0102] The tape cassette supplying device 40 includes a drive unit 432 of the holding unit 43, a first sensor 434, a second sensor 435, a third sensor 436 and a reading unit 437, a support unit moving mechanism 44, a moving mechanism 45, a trolley position detection unit 411, an alarm unit 46, a communication unit 401, and a control unit 402 that controls these.
[0103] As described above, the movement mechanism 45 is a part that moves the holding unit 43 in the X-axis direction, the Y-axis direction, and the Z-axis direction, and rotates the holding unit 43 around the Z-axis direction. For this reason, the movement mechanism 45 is provided with a motor for movement in the X-axis direction, a motor for movement in the Y-axis direction, a motor for movement in the Z-axis direction, and a motor for rotation around the Z-axis direction, and these are controlled by the control unit 402.
[0104] The notification unit 46 is a part that notifies various information visually or audibly. For example, a display device is an example of the notification unit 46 that visually notifies, and a speaker is an example of the notification unit 46 that audibly notifies. The communication unit 401 is a communication module for communicating with the management computer 100, the component mounting device main body 20a, the dolly 30, and the transport vehicle 490 wirelessly or by wire, and is connected to a communication network for free communication. The control unit 402 has a CPU, RAM, and ROM, and the CPU loads a program in the ROM into the RAM and executes it to control each part of the tape cassette supplying device 40. The ROM stores a reference position of each feeder 311 and a first target insertion position of each feeder 311. The reference position of each feeder 311 is an ideal position (design position) of a predetermined part of each feeder 311. The first target insertion position of each feeder 311 is a target position for inserting the carrier tape 83 into the tape insertion port 320 of each feeder 311. A plurality of the reference positions and the first target insertion positions are provided so as to correspond to the respective feeders 311. The control unit 402 may control each unit based on a command from the management computer 100.
[0105] [Tape cassette supply method] The tape cassette supplying method according to the first embodiment will be described.
[0106] First, the correction process of the first target insertion position will be described. The correction process is executed every time the tape cassette supplying device 40 is connected to the component mounting device 20. Fig. 17 is a plan view showing a state where a part of the holding portion 43 is brought into contact with the upper surface of the feeder 311 in the correction process according to the first embodiment. Fig. 18 is a plan view showing a state where a part of the holding portion 43 is brought into contact with the side surface of the feeder 311 in the correction process according to the first embodiment.
[0107] As shown in FIG. 17, the control unit 402 controls the moving mechanism 45 to move the holding unit 43 until one of the chucks 431 contacts the upper surface of the feeder 311. At this time, the control unit 402 controls the moving mechanism 45 based on the reference position of the feeder 311 to move the holding unit 43 so that one of the chucks 431 approaches or passes the upper surface of the feeder 311 from the positive direction of the Z axis. When one of the chucks 431 contacts the upper surface of the feeder 311 due to this movement, a current value caused by this contact is output from each motor to the control unit 402. The control unit detects that one of the chucks 431 has contacted the upper surface of the feeder 311 by analyzing the current value from each motor, and obtains position information regarding the contact position in the Z axis direction.
[0108] Next, as shown in FIG. 18, the control unit 402 controls the moving mechanism 45 to move the holding unit 43 until one chuck unit 431 comes into contact with the side surface of the feeder 311 (the side surface in the negative X-axis direction). At this time, the control unit 402 controls the moving mechanism 45 based on the reference position of the feeder 311 to move the holding unit 43 so that one chuck unit 431 approaches or passes by the side surface of the feeder 311 from the negative X-axis direction. When one chuck unit 431 comes into contact with the side surface of the feeder 311 due to this movement, a current value caused by this contact is output from each motor to the control unit 402. The control unit detects that one chuck unit 431 has come into contact with the side surface of the feeder 311 by analyzing the current value from each motor, and obtains position information regarding the contact position in the X-axis direction.
[0109] Next, although not shown in the drawings, the control unit 402 controls the moving mechanism 45 to move the holding unit 43 until one of the chuck units 431 comes into contact with the tip surface (the end surface in the negative Y-axis direction) of the feeder 311. In the same procedure as described above, the control unit 402 detects that one of the chuck units 431 has come into contact with the tip surface of the feeder 311, and acquires position information on the contact position in the Y-axis direction. In this manner, the control unit 402 is an example of a position acquisition unit according to the present disclosure. The position acquisition unit is a part that acquires position information on the contact position when the holding unit 43 comes into contact with the feeder 311, which is a part of the component mounting device 20.
[0110] Thereafter, the control unit 402 corrects the first target insertion position based on the acquired position information of the feeder 311 and the reference position of the feeder 311. That is, the control unit 402 is an example of an insertion position correction unit according to the present disclosure. Specifically, the control unit 402 calculates a difference between the acquired position information of the feeder 311 and the reference position of the feeder 311, and adds the difference to the first target insertion position, thereby correcting the first target insertion position. Taking the Z-axis direction as an example, the control unit 402 calculates a difference between the Z-axis coordinate value of the position information and the Z-axis coordinate value of the reference position, and adds it to the Z-axis coordinate position of the first target insertion position. The first target insertion position is corrected by performing the same processing in the X-axis and Y-axis directions. The control unit 402 executes the above-mentioned correction processing for each feeder 311. As a result, the first target insertion position of each feeder 311 is corrected.
[0111] Next, the operation of holding the tape cassette 60 by the holding section 43 will be described. Figures 19A to 19C are explanatory diagrams showing the holding operation of the holding section 43 according to embodiment 1. The first tape cassette 61 will be described below as an example, but the second tape cassette 65 is generally similar. Furthermore, the example shown here is when the first tape cassette 61 is being supplied.
[0112] 19A, the control unit 402 controls the movement mechanism 45 to move the holding unit 43 to directly above the first tape cassette 61 supported by the second tape cassette support unit 421. As a result, the holding unit 43 moves to directly above the gripped portion 625 of the first tape cassette 61 supported by the second tape cassette support unit 421.
[0113] The first sensor 434 detects whether or not the first tape cassette 61 is present directly below it, and outputs the detection result to the control unit 402. If the first sensor 434 does not detect the presence of the first tape cassette 61, the control unit 402 controls the notification unit 46 to notify an error. By recognizing this notification, the worker can deal with the error appropriately.
[0114] On the other hand, when the first sensor 434 detects the presence of the first tape cassette 61, the control unit 402 acquires the detection result of the third sensor 436 to determine the type of tape cassette 60. Specifically, when the third sensor 436 detects the identification shape 611a of the first tape cassette 61, the control unit 402 determines that the detection target is the first tape cassette 61. When the third sensor 436 does not detect the identification shape 611a of the first tape cassette 61, the control unit 402 determines that the detection target is the second tape cassette 65.
[0115] 19B, the control unit 402 controls the moving mechanism 45 to lower the holding unit 43 until the pair of chucks 431 can grip the gripped portion 625. At this time, each positioning unit 433 is inserted into each recess 611b of the first tape cassette 61. In this state, the reading unit 437 is disposed opposite the tag 626 of the first tape cassette 61, and is capable of reading and writing information on the tag 626. The reading unit 437 outputs the information read from the tag 626 to the control unit 402. The control unit 402 outputs the acquired information from the communication unit 401 to the management computer 100. This information is used by the management computer 100 to comprehensively control the component mounting device main body 20a, the cart 30, and the tape cassette supplying device 40.
[0116] 19C, the control unit 402 controls the drive unit 432 to narrow the distance between the pair of chuck portions 431 and grip the gripped portion 625 with the pair of chuck portions 431. As a result, the first tape cassette 61 is held by the holding portion 43.
[0117] Thereafter, the control unit 402 controls the moving mechanism 45 to raise the holding unit 43. As a result, the first tape cassette 61 is lifted by the holding unit 43. At this time, if the positioning unit 433 is properly inserted into the recess 611b, the base of the positioning unit 433 located in the second sensor 435 returns to a position that does not block the detection light of the second sensor 435, and the second sensor 435 receives the transmitted light. As a result, the fact that the first tape cassette 61 and the holding unit 43 are in a normal positional relationship is output to the control unit 402. On the other hand, if the base of the positioning unit 433 does not return to a position that does not block the detection light of the second sensor 435, that is, if the second sensor 435 detects the base of the positioning unit 433, the fact that the first tape cassette 61 and the holding unit 43 are not in a normal positional relationship is output to the control unit 402, and the control unit 402 controls the notification unit 46 to notify an error. The operator can appropriately deal with the error by recognizing this notification.
[0118] Thereafter, the control unit 402 controls the movement mechanism 45 based on the corrected first target insertion position to move the holding unit 43 and the first tape cassette 61. As a result, the tip of the first slide support unit 94 of the first tape cassette 61 is positioned at the tape insertion opening 320 of the feeder 311.
[0119] 20 is an explanatory diagram showing a state in which the first slide support portion 94 of the first tape cassette 61 according to embodiment 1 is arranged at the tape insertion opening 320 of the feeder 311. With this arrangement, the carrier tape 83 is fed from the first tape feed portion 93 of the first slide support portion 94 and engages with the sprocket of the tape insertion opening 320.
[0120] [effect] As described above, after acquiring position information on the contact position when the holding unit 43 contacts the feeder 311, which is a part of the component mounting device 20, the first target insertion position is corrected based on the position information and the reference position of the feeder 311. In other words, even if the actual feeder 311 is misaligned from the reference position, the first target insertion position can be corrected taking into account this misalignment. Since the carrier tape 83 is guided based on the corrected first target insertion position, the carrier tape 83 can be aligned even with the misaligned tape insertion port 320. Therefore, the supply performance of the carrier tape 83 to the feeder 311 can be improved.
[0121] When the control unit 402 acquires position information on the contact position when the holding unit 43 contacts the feeder 311, the control unit 402 calculates the difference between the position information and the reference position of the feeder 311, and adds the difference to the first target insertion position. In other words, the first target insertion position is corrected based on the difference between the current position information of the feeder 311 and the reference position, so that the correction can be made more accurately.
[0122] The control unit 402 acquires the position information even when the holding unit 43 is not holding a tape cassette 60. This makes it possible to correct the first target insertion position when the holding unit 43 is holding only the carrier tape 83. In addition, by using the acquired position information relating to the position of the feeder 311, it is possible to correct the target position of the holding unit 43 when the holding unit 43 retrieves an empty tape cassette 60.
[0123] Since the control unit 402 obtains the position information every time the tape cassette supplying device 40 is connected to the component mounting device 20, the first target insertion position can be corrected every time. Therefore, the accuracy of the correction of the first target insertion position can be maintained.
[0124] Since the control unit 402 acquires the position information of each of the multiple feeders 311, it is possible to correct the first target insertion position for each feeder 311. Therefore, it is possible to improve the supply performance of the carrier tape 83 for each feeder 311.
[0125] The control unit 402 may acquire only the first feeder position information, which is the position information of only one feeder 311 (first feeder). In this case, the control unit 402 may correct the second target insertion position for inserting the carrier tape 83 into the tape insertion port 320 of the other feeder 311 (second feeder) based on the first feeder position information and the reference position of the first feeder. The control unit 402 recognizes the reference position and the target insertion position of each feeder 311 in advance. Therefore, the control unit 402 can correct the second target insertion position by calculating the difference between the position information of the first feeder and the reference position of the first feeder and adding the difference to the second target insertion position of the second feeder.
[0126] In this way, the second target insertion position of the second feeder is corrected based on the first feeder position information and the reference position of the first feeder. In other words, when correcting the second target insertion position, the first feeder position information and the first feeder reference position are used, so it is possible to omit obtaining the position information of the second feeder. Therefore, the correction process can be simplified.
[0127] (Embodiment 2) A description will be given of embodiment 2. Portions equivalent to those in embodiment 1 above will be given the same reference numerals and the description thereof may be omitted.
[0128] In the first embodiment, a case has been exemplified in which the control unit 402 acquires position information of the feeder 311 by bringing the holding unit 43 that is not holding the tape cassette 60 into contact with the feeder 311. In the second embodiment, a case will be described in which the holding unit 43 that holds the tape cassette 60 acquires position information of the feeder 311 by bringing the tape feed unit (first tape feed unit 93, second tape feed unit 293) of the tape cassette 60 into contact with the feeder 311. Note that, although the first tape cassette 61 will be described as an example here, the same applies to the second tape cassette 65.
[0129] FIG. 21 is a plan view showing a state in which the first tape feeding portion 93 of the first tape cassette 61 held by the holding portion 43 is brought into contact with the feeder 311 in the correction process according to the second embodiment.
[0130] As shown in FIG. 21, the control unit 402 controls the movement mechanism 45 to move the holding unit 43 until the first tape feed unit 93 of the first tape cassette 61 held by the holding unit 43 comes into contact with the vicinity of the tape insertion opening 320 of the feeder 311. At this time, the control unit 402 controls the movement mechanism 45 based on the reference position of the feeder 311 and the dimensions of each part of the first tape cassette 61 held by the holding unit 43. In FIG. 21, the control unit 402 moves the holding unit 43 so that the first tape feed unit 93 approaches or passes by the side surface of the tape insertion opening 320 from the positive direction of the X axis. When this movement causes the first tape feed unit 93 to come into contact with the side surface of the tape insertion opening 320, a current value caused by this contact is output from each motor to the control unit 402. The control unit detects that the first tape feed unit 93 has come into contact with the side surface of the tape insertion opening 320 by analyzing the current value from each motor, and obtains position information regarding the contact position in the X axis direction. The position information in the Y-axis direction and the position information in the Z-axis direction are also acquired by the control unit 402 through basically the same processing. Thereafter, the control unit 402 corrects the first target insertion position based on the acquired position information of the feeder 311 and the reference position of the feeder 311.
[0131] In this way, the control unit 402 obtains position information relating to the position of the feeder 311 when the first tape feed unit 93 comes into contact with the feeder 311. Here, the first tape feed unit 93 is a part that feeds the carrier tape 83 to the tape insertion opening 320. For this reason, it is easy to bring the first tape feed unit 93 into contact with the vicinity of the tape insertion opening 320. If position information can be obtained by bringing the first tape feed unit 93 into contact with the vicinity of the tape insertion opening 320, it is possible to improve the accuracy of correction of the first target insertion position.
[0132] (Embodiment 3) A description will be given of embodiment 3. Portions equivalent to those in embodiment 1 above will be given the same reference numerals and the description thereof may be omitted.
[0133] In the third embodiment, a case will be described where the first tape feed section 93 is positioned on the feeder 311 when in contact. FIG. 22 is a perspective view showing the first tape feed section 93a and the feeder 311a according to the third embodiment. As shown in FIG. 22, a pair of positioning sections 95a is provided at the tip end (the end in the positive direction of the Y axis) of the first tape feed section 93a. Specifically, the pair of positioning sections 95a are arranged side by side in the Z axis direction and protrude in the positive direction of the Y axis from the tip end of the first tape feed section 93a. The tip end of each positioning section 95a has a tapered shape. Each positioning section 95a is arranged at a position that does not affect the feeding of the carrier tape 83.
[0134] The feeder 311a is provided with a pair of connecting parts 322a to which each positioning part 95a is connected. The pair of connecting parts 322a is disposed near the tape insertion opening 320 of the feeder 311a. The pair of connecting parts 322a are block bodies disposed side by side in the Z-axis direction. A recess 323a is formed on the surface of each connecting part 322a facing the negative Y-axis direction. The positioning part 95a is positioned relative to the feeder 311a by inserting the positioning part 95a into this recess 323a.
[0135] 23 is a schematic cross-sectional view showing a state in which the positioning portion 95a according to the third embodiment contacts the recessed portion 323a. The recessed portion 323a has a tapered portion 324a whose inner diameter decreases toward the positive direction of the Y axis, and a cylindrical portion 325a which is a portion in the positive direction of the Y axis than the tapered portion 324a. For example, if the holding portion 43 is displaced in the negative direction of the Z axis with respect to the feeder 311a, the positioning portion 95a is also displaced in the negative direction of the Z axis from the correct position, so that the tip of the positioning portion 95a contacts the surface of the tapered portion 324a in the negative direction of the Z axis during insertion. As a result, a reaction force in the positive direction of the Z axis (see arrow Y1 in FIG. 23) acts on the holding portion 43 via the positioning portion 95a.
[0136] Here, when the holding unit 43 receives a reaction force, a current value caused by the reaction force is output from each motor to the control unit 402. The control unit 402 acquires the magnitude and direction of the reaction force received by the holding unit 43 by analyzing the current value from each motor. In other words, the moving mechanism 45 and the control unit 402 are an example of a reaction force detection unit that detects the reaction force. Note that a dedicated reaction force sensor that directly detects the reaction force may be used as the reaction force detection unit.
[0137] The control unit 402 controls the moving mechanism 45 to move the holding unit 43 so as to reduce the obtained reaction force. That is, the positioning unit 95a is inserted into the cylindrical unit 325a while retreating from the tapered unit 324a. When the positioning unit 95a fits into the cylindrical unit 325a, the first tape feeding unit 93a is positioned at the feeder 311a. In this state, the control unit 402 obtains position information of the feeder 311a. Thereafter, the control unit 402 corrects the first target insertion position based on the obtained position information of the feeder 311a and the reference position of the feeder 311a.
[0138] In this way, the control unit 402 acquires the position information while the first tape feeding unit 93a is positioned relative to the feeder 311a by the positioning unit 95a, so that the control unit 402 can acquire the position information stably. Therefore, the position information is less likely to vary, and as a result, the accuracy of the correction can be improved.
[0139] In particular, in this embodiment, the control unit 402 acquires the position information in a state in which the positioning unit 95a is positioned on the feeder 311a after the first tape feeding unit 93a comes into contact with the feeder 311a, and therefore, the control unit 402 can acquire the position information after the vibrations immediately after the contact are alleviated. Therefore, the influence of the vibrations on the position information can be suppressed, and as a result, the accuracy of the correction can be improved.
[0140] Since the positioning is performed while the movement mechanism 45 reduces the reaction force against the holding portion 43, the stability of the positioning can be improved.
[0141] (Embodiment 4) A description will be given of embodiment 4. Portions equivalent to those in embodiment 1 above will be given the same reference numerals and the description thereof may be omitted.
[0142] In the first embodiment, the control unit 402 acquires position information on the contact position when the holding unit 43 contacts the feeder 311, but the contact object of the holding unit 43 may be other than the feeder 311 as long as it is a component of the component mounting device 20. In the fourth embodiment, a case will be described in which the contact object of the holding unit 43 is a contact member 330b provided on the cart 30b.
[0143] Fig. 24 is a perspective view showing a carriage 30b according to embodiment 4. In the carriage 30b shown in Fig. 24, a pair of abutment members 330b is provided at positions sandwiching a plurality of feeders 311 in the X-axis direction. The abutment members 330b are elongated members in the Y-axis direction, and their ends in the negative Y-axis direction are disposed further in the negative Y-axis direction than the feeders 311.
[0144] The control unit 402 controls the moving mechanism 45 to move the holding unit 43 until the holding unit 43 comes into contact with the upper surface of one of the contact members 330b. Specifically, the control unit 402 moves the holding unit 43 so that the holding unit 43 approaches or passes over the upper surface of one of the contact members 330b. When the holding unit 43 comes into contact with the upper surface of one of the contact members 330b by this movement, a current value caused by this contact is output from each motor to the control unit 402. The control unit detects that the holding unit 43 has come into contact with the upper surface of one of the contact members 330b by analyzing the current value from each motor, and obtains position information regarding the contact position in the Z axis direction. The position information in the X axis direction and the position information in the Y axis direction are also obtained by the control unit 402 by basically performing the same process. The control unit 402 performs the same process on the other of the contact members 330b to obtain position information on the other of the contact members 330b.
[0145] The control unit 402 linearly interpolates the position information of one contact member 330b and the position information of the other contact member 330b in the XYZ space, i.e., in at least one of the X-axis direction, the Y-axis direction, and the Z-axis direction. The control unit 402 can calculate the current position information of each feeder 311 by comparing this result with the reference position of each feeder 311. Thereafter, the control unit 402 corrects the first target insertion position of each feeder 311 based on the calculated position information of each feeder 311 and the reference position of each feeder 311.
[0146] In this way, the control unit 402 obtains position information when the holding unit 43 contacts each of the pair of contact members 330b. In other words, even if the holding unit 43 does not directly contact the feeder 311, the first target insertion position can be corrected based on the position information obtained by contacting the contact members 330b. This makes it possible to reduce the load on the feeder 311 that is applied by contacting the feeder 311.
[0147] Since the position information of each feeder 311 that is the subject of correction of the first target insertion position is calculated based on the position information when it contacts each of the pair of contact members 330b, it is possible to obtain the current position information of each feeder 311 and correct the first target insertion position without directly contacting each feeder 311. This simplifies the correction process of the first target insertion position of each feeder 311.
[0148] In the present embodiment, the control unit 402 acquires the position information of the contact member 330b by bringing the holding unit 43 into contact with the contact member 330b. However, the control unit 402 may acquire the position information of the contact member 330b by bringing the tape cassette 60 held by the holding unit 43 into contact with the contact member 330b.
[0149] (Embodiment 5) A description will be given of embodiment 5. Portions equivalent to those in the above embodiments will be given the same reference numerals and the description thereof will be omitted in some cases.
[0150] In the second embodiment, the tape cassette 60 has a tape feed unit (first tape feed unit 93, second tape feed unit 293), and the tape feed unit is used for the correction process. In the fifth embodiment, the case where the tape feed unit is provided in the holder will be described.
[0151] Fig. 25 is a plan view showing a schematic configuration of holding section 43c according to embodiment 5. As shown in Fig. 25, holding section 43c has holding main body section 430c, holding body 440c, and tape feed section 450c.
[0152] The holding body 430c is formed to be elongated in the Y-axis direction, and is connected to the moving mechanism 45. A reading unit 437 is provided at the lower part of the middle part of the holding body 430c in the Y-axis direction.
[0153] A holding body 440c is provided on the lower part of the holding body 430c in the negative Y-axis direction. The lower part of the holding body 430c in the positive Y-axis direction is inclined along the feed direction, and a tape feed section 450c is provided on the lower part. In this manner, the holding body 440c and the tape feed section 450c are provided integrally via the holding body 430c.
[0154] The holder 440c is a portion that holds the tape cassette 60c (see FIG. 26) supported by the second tape cassette support portion 421. Specifically, the holder 440c has a hanging portion 441c that protrudes downward from the holding main body portion 430c. The hanging portion 441c is a hook formed in a substantially L-shape, and is attached to the holding main body portion 430c with its tip portion facing in the positive direction of the Y axis. A protrusion 442c that protrudes upward is provided at the tip portion of the hanging portion 441c. The tip portion and the protrusion 442c of the hanging portion 441c engage with a notch portion 632c (described later) of the tape cassette 60c, thereby suspending and holding the tape cassette 60c.
[0155] The tape feed section 450c is a section that feeds out the carrier tape 83 from the tape cassette 60c. The tape feed section 450c has a plurality of tape feed mechanisms 451c, a tape support section 452c, and a positioning section 453c.
[0156] The multiple tape feeding mechanisms 451c are arranged at predetermined intervals in the feeding direction of the carrier tape 83. Each tape feeding mechanism 451c is a sprocket that is driven to rotate. The teeth of the sprocket that constitutes the tape feeding mechanism 451c engage with the feed hole 88 of the carrier tape 83.
[0157] The tape support portion 452c is a portion that supports the carrier tape 83 fed out from the tape cassette 60. The tape support portion 452c is provided at the tip portion of the holding main body portion 430c in the positive direction of the Y axis. Specifically, the tape support portion 452c has a pair of support plates 454c that support the carrier tape 83 from below. The pair of support plates 454c are disposed at a predetermined interval in the X axis direction. The lower ends of the pair of support plates 454c are bent so as to approach each other. Both ends of the carrier tape 83 in the X axis direction are supported by the lower ends of the pair of support plates 454c.
[0158] The positioning portion 453c is a portion for positioning the position of the leading end of the carrier tape 83 fed out from the tape cassette 60c relative to the tape feeding portion 450c. Specifically, the positioning portion 453c is disposed upstream of each tape feeding mechanism 451c in the feeding direction. The positioning portion 453c has a pair of pin members 455c protruding from the holding main body portion 430c. Each pin member 455c is inserted into and engaged with each opening 933c (described later) of the tape cassette 60.
[0159] 26 is an explanatory diagram showing a state in which each pin member 455c according to the fifth embodiment is engaged with each opening 933c of the tape cassette 60c. Here, the second tape cassette 65c is illustrated as an example of the tape cassette 60c. The second tape cassette 65c has a flat outer shape with its thickness direction in the X-axis direction, and includes a second storage section 66c and a tape support section 93c, but does not include a tape feed section.
[0160] The second storage section 66c has a second storage space H2 (storage space) that stores the second roll body 82. An engaged portion 63c that engages with the holder 440c is provided at an end in the negative Y-axis direction in the upper part of the second storage section 66c. The engaged portion 63c has a portion in which the upper part of the second storage section 66c is cut out in a substantially L-shape. Specifically, the engaged portion 63c has a support beam 631c extending in the Y-axis direction, and the support beam 631c forms a part of the L-shaped cutout portion 632c. An end of the support beam 631c in the negative Y-axis direction protrudes downward.
[0161] The tape support portion 93c is a portion that supports the carrier tape 83 that is fed out from the second tape cassette 65c. The tape support portion 93c is connected to the end of the engaged portion 63c in the positive direction of the Y axis in the second storage portion 66c. The tape support portion 93c is disposed in a position that tilts upward toward the positive direction of the Y axis. It can also be said that the tape support portion 93c extends along the feed direction when the carrier tape 83 is fed out from the second roll body 82. The tape support portion 93c has a pair of support plates 931c that support the carrier tape 83 from below. The pair of support plates 931c are spaced apart from each other by a predetermined distance in the X axis direction, and are adapted to support both ends of the carrier tape 83 in the X axis direction.
[0162] In the tape support portion 93c, a plurality of openings 933c for positioning the pin members 455c are formed in the negative Y-axis direction from the pair of support plates 931c. When each pin member 455c is engaged with each opening 933c, the second tape cassette 65c and the tape feed portion 450c are positioned relative to each other. This also determines the position of the tip of the carrier tape 83 fed out from the second tape cassette 65c.
[0163] Thereafter, the control unit 402 controls the moving mechanism 45 to temporarily raise the holding unit 43c. As a result, the pin members 455c of the tape feed unit 450c are separated from the openings 933c. At this time, since the carrier tape 83 is supported by the tape support unit 452c while being engaged with the tape feed mechanisms 451c, the leading end of the carrier tape 83 is pulled out from the second tape cassette 65c.
[0164] Thereafter, the control unit 402 controls the movement mechanism 45 to move the holding portion 43c, thereby moving the holding body 440c to a position where it can hold the second tape cassette 65c. Specifically, the control unit 402 moves the holding portion 43c to a position where the hanging portion 441c of the holding body 440c can engage with the notch portion 632c of the second tape cassette 65c. This allows the holding portion 43c to hold the second tape cassette 65c.
[0165] Also, as shown in FIG. 25, when the holding portion 43c is not holding the second tape cassette 65c, the control portion 402 can control the moving mechanism 45 to bring the tape feed portion 450c into contact with the feeder 311, thereby acquiring position information of the feeder 311 and correcting the first target insertion position.
[0166] (others) Although the component mounting system 10 according to the embodiment of the present invention has been described above, the present invention is not limited to this embodiment. In other words, the embodiment disclosed herein is illustrative in all respects, and the scope of the present invention includes all modifications within the meaning and scope of the claims.
[0167] For example, in each of the above embodiments, the control unit 402 acquires position information in each of the X-axis direction, the Y-axis direction, and the Z-axis direction, but may acquire position information in at least one of the X-axis direction, the Y-axis direction, and the Z-axis direction. In this case, the control unit may correct the first target insertion position based on the acquired at least one piece of position information.
[0168] Furthermore, the control unit 402 (insertion position correction unit) may correct the target holding position based on the position information of the feeder 311 and the reference position of the feeder 311. That is, the control unit 402 may calculate a difference between the position information of the feeder 311 and the reference position of the feeder 311, and correct the target holding position by adding this difference to the target holding position. Similarly, the control unit 402 may correct the target installation position at which the holding unit 43 installs the tape cassette 60 on the first tape cassette support unit 70, based on the position information of the feeder 311 and the reference position of the feeder 311. That is, at least one of the target holding position and the target installation position is corrected based on the position information of the feeder 311 and the reference position of the feeder 311. That is, when at least one of the target holding position and the target installation position is corrected, the position information of the feeder 311 and the reference position of the feeder 311 are used, so that it is possible to simplify the correction process of at least one of the target holding position and the target installation position.
[0169] Furthermore, configurations constructed by arbitrarily combining the components included in each of the above embodiments and their modifications are also included within the scope of the present invention. [Industrial Applicability]
