Description

[Technical field]

[0001] The present specification relates to an exchange device that automatically exchanges an exchange element that is detachably mounted on a component mounting device. [Background technology]

[0002] A technology for mass-producing circuit boards by performing substrate-to-substrate operations on printed wiring boards is becoming widespread. Substrate-to-substrate operation devices that perform substrate-to-substrate operations include component mounting devices that perform component mounting operations. A representative example of a component supply device provided in a component mounting device is a tape feeder that supplies components using a carrier tape. In recent years, technologies have been developed to automatically replace tape feeders or automatically replace tape reels around which carrier tape is wound, in order to reduce the labor required for supplying components. Examples of technologies related to this type of replacement device are disclosed in Patent Documents 1 and 2.

[0003] Patent Document 1 discloses a cassette feeder replacement system for a component mounting device, which includes a pickup work area where multiple cassette feeders are set side by side, a feeder stock area where unused and used cassette feeders are stored, and a replacement robot that replaces the cassette feeders between the pickup work area and the feeder stock area. This system is said to automate the cassette feeder replacement work and also to smoothly replace cassette feeders between areas.

[0004] Also, Patent Document 2 discloses a component mounting line including a unit storage for storing a plurality of component supply units, component supply units attached to a plurality of component mounting devices, a unit exchange device for exchanging the component supply units stored in the unit storage, and a control device for controlling the unit exchange device. According to this, it is said that the component supply units used in any of the component mounting devices can be carried in and out of the unit storage for replenishment and collection, making it easy to use. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] International Publication No. 2014 / 118995 [Patent Document 2] International Publication No. 2017 / 033268 Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, in the technical examples of the replacement device in Patent Documents 1 and 2, replacement elements (cassette-type feeders, component supply units) of the component mounting device are replaced one by one. For example, in Patent Document 1, a cassette-type feeder that has run out of components through the mounting work is collected from the pickup work area, transported to and stored in the feeder stock area, and then a new cassette-type feeder is pulled out of the feeder stock area, transported to and set in the pickup work area. During the replacement work, the mounting work is interrupted, resulting in non-productive time during which boards cannot be produced.

[0007] In addition, in many cases where a changeover is required to change the type of board being produced, multiple replacement elements of the component mounting device must be replaced, which tends to lengthen non-productive time. There is a strong demand for shortening such non-productive time and increasing the production efficiency of boards.

[0008] The problem to be solved in this specification is to provide a replacement device that can shorten the non-production time of a component mounting device and improve the production efficiency of boards. [Means for solving the problem]

[0009] This specification discloses an exchange device that exchanges exchange elements that are detachably mounted on a component supply unit of a component mounting device having a component supply unit in which exchange elements, each of which includes at least a component container that stores a plurality of parts, are arranged in an arrangement direction, the exchange device comprising: an arrangement direction moving unit that is arranged to be movable in the arrangement direction relative to the component mounting device; a plurality of attachment / detachment direction moving units that are arranged on the arrangement direction moving unit to be movable in the attachment / detachment direction of the exchange elements independently of each other relative to the arrangement direction moving unit; at least one holding unit that is provided on each of the plurality of attachment / detachment direction moving units and is capable of holding the exchange elements; an arrangement direction driving unit that moves the arrangement direction moving unit in the arrangement direction; and an attachment / detachment direction driving unit that moves the plurality of attachment / detachment direction moving units in the attachment / detachment direction independently of each other.

[0010] This specification also discloses an exchange device for exchanging exchange elements detachably mounted on a component supply unit of a component mounting device having a component supply unit in which exchange elements, including at least a component container that stores a plurality of parts, are arranged in an arrangement direction at a predetermined pitch or at a pitch that is an integer multiple of the predetermined pitch, the exchange device comprising: an arrangement direction moving unit arranged to be movable in the arrangement direction relative to the component mounting device; an attachment / detachment direction moving unit arranged on the arrangement direction moving unit to be movable in the attachment / detachment direction of the exchange elements relative to the arrangement direction moving unit; a plurality of holding units arranged on the attachment / detachment direction moving unit adjacent to the arrangement direction at the predetermined pitch or at a pitch that is an integer multiple of the predetermined pitch and capable of holding the exchange elements; an arrangement direction driving device that moves the arrangement direction moving unit in the arrangement direction; and an attachment / detachment direction driving device that moves the attachment / detachment direction moving unit in the attachment / detachment direction. Effect of the Invention

[0011] The replacement device disclosed in this specification has multiple holding units and can handle multiple replacement elements at the same time. Therefore, compared to a conventional configuration with a single holding unit, the non-productive time required for replacing replacement elements is shortened, the ratio of productive time of the component mounting device is increased, and the production efficiency of circuit boards is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] 1. Configuration of a component mounting system 9 to which the replacement device 1 of the embodiment is applied First, a configuration example of a component mounting system 9 to which the replacement device 1 of the embodiment is applied will be described. FIG. 1 is a perspective view showing a configuration example of the component mounting system 9 to which the replacement device 1 of the embodiment is applied. As shown in FIG. 1, the front, back, left and right of the component mounting system 9 are defined for convenience. The component mounting system 9 is configured by arranging a plurality of substrate-related work devices in a row in the left-right direction. That is, a solder printing device 91, a print inspection device 92, a first component mounting device 93, a second component mounting device 94, a third component mounting device 95, a substrate appearance inspection device (not shown), and a reflow device (not shown) are arranged in a row from left to right.

[0014] Each of the substrate-related work devices performs a predetermined work on the substrate, that is, substrate-related work. Specifically, the solder printing device 91 prints a paste-like solder on the substrate in a predetermined pattern shape. The print inspection device 92 takes an image of the solder printing state on the substrate and inspects it. The first component mounting device 93, the second component mounting device 94, and the third component mounting device 95 take components from the component supply section 9A and mount them on the solder on the substrate. The substrate appearance inspection device takes an image of the components mounted on the substrate and inspects the appearance state. The reflow device heats and cools the solder to ensure that the components are soldered. The substrate-related work is not limited to the above-mentioned work contents, but also includes various associated work. For example, the substrate-related work includes the work of carrying in and out the substrate, the positioning work, and the confirmation work of taking images of the substrate and components to grasp their positions and postures.

[0015] The first component mounting device 93, the second component mounting device 94, and the third component mounting device 95 have the same structure. The component mounting devices (93, 94, 95) each have a component supply unit 9A, a spare feeder storage unit 9B, a board transport device not visible in FIG. 1, and a component transfer device.

[0016] The component supply unit 9A is disposed at approximately the middle height on the front side of the machine base 99. The component supply unit 9A has a plurality of slots extending in the front-rear direction and formed parallel to one another at a predetermined pitch Ps (see Figs. 5 to 7). A tape feeder 8 is inserted and installed in each slot of the component supply unit 9A. In other words, the multiple tape feeders 8 are arranged side by side in the left-right direction of Fig. 1.

[0017] Tape feeder 8 is a component supplying device detachably mounted on component supplying unit 9A, and corresponds to a replaceable element. The left-right direction in Fig. 1 corresponds to the arrangement direction of the replaceable elements (hereinafter simply referred to as the arrangement direction), and the front-rear direction in Fig. 1 corresponds to the attachment / detachment direction of the replaceable elements (hereinafter simply referred to as the attachment / detachment direction). Tape feeder 8 is used interchangeably in first component mounting device 93, second component mounting device 94, and third component mounting device 95.

[0018] The spare feeder storage section 9B is disposed below the component supply section 9A on the front side of the machine base 99. The spare feeder storage section 9B also has a plurality of slots extending in the front-rear direction and formed parallel to each other at a predetermined pitch Ps. The slots of the spare feeder storage section 9B are arranged to temporarily store spare tape feeders 8 that are ready for use and tape feeders 8 that have been used. The board transport device loads, positions, and unloads boards. The component transfer device uses a component mounting tool such as a suction nozzle to pick up components from the component supply section 9A and mounts them on the board.

[0019] The component mounting system 9 is also provided with a feeder storage device 96, a line management device 97, and an exchange device 1 of the embodiment. The feeder storage device 96 is adjacent to the left side of the solder printing device 91 and is disposed at the same height as the component supply unit 9A of the component mounting device (93, 94, 95). The feeder storage device 96 also has a plurality of slots extending in the front-rear direction and formed parallel to each other at a predetermined pitch Ps. The slots of the feeder storage device 96 also store tape feeders 8 that are ready for use and tape feeders 8 that have been used.

[0020] The line management device 97 is disposed adjacent to the left side of the feeder storage device 96. The line management device 97 is connected for communication with a plurality of substrate-related operation devices. The line management device 97 manages job data describing the work contents of substrate-related operations that differ for each type of substrate. The line management device 97 transmits each job data to the substrate-related operation devices based on a production plan. The line management device 97 further monitors the operating status of the substrate-related operation devices.

[0021] 2. Structure of tape feeder 8 Next, the structure of tape feeder 8 will be described. Fig. 2 is a side view of tape feeder 8, which corresponds to the replaceable element. Tape feeder 8 is configured to be thin in the width direction by assembling various members to frame body 81 including side plates. Tape feeder 8 has frame body 81, reel housing frame 82, housing plate 83, opening / closing plate 84, tape feeding section 85, component supply position 86, feeder control section 87, protrusion 88, upper positioning pin 89, lower positioning pin 8A, connector 8B, and lock section 8C.

[0022] The reel storage frame 82 is made up of multiple frame members that form a large circular internal space roughly in the center of the frame body 81. The reel storage frame 82 stores the tape reel TR in the internal space so that it can rotate freely. A storage plate 83 is attached near the bottom of the reel storage frame 82. The distance between the storage plate 83 and the side plate of the frame body 81 is set to be slightly larger than the thickness of the tape reel TR. The storage plate 83 prevents the tape reel TR from falling off.

[0023] An opening / closing plate 84 is attached above the mid-height of the reel housing frame 82. The distance between the opening / closing plate 84 and the side plate of the frame body 81 is also set to be slightly larger than the thickness of the tape reel TR. The opening / closing plate 84 is supported by the frame body 81 at two points 841, front and rear, on the upper part, so that it opens upward. By opening the opening / closing plate 84, it becomes possible to replace the tape reel TR. A carrier tape containing multiple components is wound around the tape reel TR. The tape reel TR corresponds to a component container that contains multiple components.

[0024] The tape feeding unit 85 is disposed at the upper front part of the frame 81. The tape feeding unit 85 pulls out the carrier tape from the tape reel TR and feeds it to a component supply position 86 provided at the front part of the top surface of the frame 81. The tape feeding unit 85 is composed of a sprocket having teeth that fit into feed holes in the carrier tape, a motor that rotates the sprocket, and the like.

[0025] The feeder control unit 87 is disposed at the rear lower portion of the frame 81. The feeder control unit 87 controls the tape feeding unit 85 and also monitors the state of the lock unit 8C. The feeder control unit 87 is connected for communication with a control device on the main body side of the component mounting device (93, 94, 95) via a connector 8B.

[0026] The protrusion 88 is provided on the bottom surface of the frame 81. The protrusion 88 is adapted to be inserted into any of the slots of the component supply unit 9A, the spare feeder storage unit 9B, and the feeder storage device 96. The protrusion 88 is further adapted to be inserted into a slot 314 of a case 31 of a replacement unit 3 of the replacement device 1, which will be described later. As a result, during replacement, the protrusion 88 is guided by the slot 314, and the tape feeder 8 is transferred from the replacement device 1 to the component supply unit 9A, etc., or transferred in the opposite direction.

[0027] The upper positioning pin 89 and the lower positioning pin 8A are provided at a distance from each other on the upper part of the front surface of the frame 81. The upper positioning pin 89 and the lower positioning pin 8A fit into positioning holes in the component supply unit 9A to position the tape feeder 8. The connector 8B is disposed between the upper positioning pin 89 and the lower positioning pin 8A. The connector 8B is responsible for supplying power and connecting communications to the tape feeder 8. When the tape feeder 8 is positioned, the connector 8B automatically fits into the receiving connector of the component supply unit 9A.

[0028] The locking portion 8C is disposed at the upper rear portion of the frame 81. FIG. 3 is a side view showing the configuration of the vicinity of the locking portion 8C of the tape feeder 8 and the internal configuration of the attachment / detachment direction moving portion 32 (described later) of the exchanging device 1. The locking portion 8C is composed of a locking pin 8D, a locking spring 8E, a locking operation member 8F, a locking sensor 8L, and the like. The locking pin 8D is a cylindrical member, and is held by the frame 81 so as to be movable up and down. The locking spring 8E is formed in a coil shape, and is disposed inside the locking pin 8D. One end of the locking spring 8E is coupled to the frame 81, and the other end is coupled to the locking pin 8D.

[0029] The lock spring 8E biases the lock pin 8D upward. In the tape feeder 8 equipped in the component supply unit 9A, the lock pin 8D, which has risen due to the bias, protrudes from the upper surface of the frame body 81 and fits into the lock hole 9H of the component supply unit 9A. This brings the lock unit 8C into a locked state, preventing the tape feeder 8 from coming off or rattling.

[0030] The lock operation member 8F is a Y-shaped member having a swing fulcrum 8G. The swing fulcrum 8G is swingably supported by the frame body 81. An action arm 8H extending forward from the swing fulcrum 8G is engaged with the lower end of the lock pin 8D. A release arm 8J extending upward from the swing fulcrum 8G is pushed forward by a direct operating member 61, which will be described later. A manual arm 8K extending rearward from the swing fulcrum 8G protrudes from the rear surface of the frame body 81. The manual arm 8K is pushed upward by the operation of the operator.

[0031] When the release arm 8J or the manual arm 8K is pushed, the lock operation member 8F swings clockwise in FIG. 3 around the swing fulcrum 8G. At this time, the action arm 8H lowers the lock pin 8D against the lock spring 8E. Then, the lock pin 8D comes out of the lock hole 9H. This causes the lock portion 8C to transition from the locked state to the released state (see FIG. 8). Also, the tape feeder 8 becomes ready for withdrawal from the slot.

[0032] The lock sensor 8L detects the state of the locking unit 8C, i.e., whether it is in a locked state or an unlocked state. The lock sensor 8L outputs the detection result to the feeder control unit 87 via the output cable 8M. In the tape feeder 8 installed in the component supplying unit 9A, the feeder control unit 87 does not proceed with the component supplying operation when the locking unit 8C is in an unlocked state. This is because it is determined that the tape feeder 8 is not in a good installation position.

[0033] 3, a holding plate 8N is provided vertically on the rear side of the lock portion 8C. The holding plate 8N is a portion that is held by the holding portion 5. The holding plate 8N has a holding hole 8P in the center. The holding hole 8P is located at the same height (predetermined height) as the connector 8B. When viewed from behind, the release arm 8J of the lock operation member 8F is located on an extension of the holding hole 8P.

[0034] A number of types of tape feeders 8 are available with different width dimensions in the arrangement direction to correspond to a number of different thicknesses of the tape reels TR. Standard tape feeders 8X have a width dimension equal to or smaller than a predetermined pitch Ps, and are installed side by side in adjacent slots. In other words, the standard tape feeders 8X are arranged in the arrangement direction at a predetermined pitch Ps (see FIG. 6).

[0035] Large tape feeders 8Y whose width dimension exceeds the predetermined pitch Ps but is not more than twice as large are provided, occupying two slots. In other words, the large tape feeders 8Y are arranged in the arrangement direction at a pitch twice the predetermined pitch Ps (see FIG. 6). Furthermore, extra-large tape feeders 8Z whose width dimension exceeds twice the predetermined pitch Ps are provided, occupying three or more slots. In other words, the extra-large tape feeders 8Z are arranged in the arrangement direction at a pitch three or more times the predetermined pitch Ps (see FIG. 7).

[0036] 3. Configuration of the exchange device 1 according to the embodiment We now move on to a description of the exchanging device 1 of the embodiment. The exchanging device 1 automatically exchanges tape feeders 8. In detail, the exchanging device 1 exchanges tape feeders 8 between a component supply unit 9A of a component mounting device (93, 94, 95) and a spare feeder storage unit 9B. The exchanging device 1 also moves between the component mounting device (93, 94, 95) and a feeder storage device 96, transporting and exchanging tape feeders 8.

[0037] As shown in FIG. 1, the replacement device 1 is composed of an arrangement direction moving unit 2, an arrangement direction driving device 20, a replacement unit 3, and various components provided inside the replacement unit 3. The arrangement direction moving unit 2 is provided so as to be movable in the arrangement direction relative to the component mounting devices (93, 94, 95). The arrangement direction moving unit 2 is a vertically long box-shaped member with an open front. The arrangement direction driving device 20 moves the arrangement direction moving unit 2 in the arrangement direction. The arrangement direction driving device 20 is composed of a track section provided on the non-moving side, an engagement section provided on the moving side and movably engaged with the track section, and a driving source that generates power for movement.

[0038] Middle rail 21 and lower rail 22, which correspond to the track section, are provided on the rear surface of machine bases 99 of the multiple substrate-related operation devices and on the rear surface of feeder storage device 96, respectively. Middle rail 21 and lower rail 22 extend in the arrangement direction. The height position of middle rail 21 is uniformly set between component supply unit 9A and spare feeder storage unit 9B. The height position of lower rail 22 is uniformly set below spare feeder storage unit 9B. As a result, the multiple middle rails 21 and the multiple lower rails 22 form two parallel track sections that continue from feeder storage device 96 to third component mounting device 95.

[0039] Middle stage running section 23 and lower stage running section 24, which correspond to the engagement section, are disposed on the left and right sides of the front side of arrangement direction moving section 2. Middle stage running section 23 engages with middle stage rail 21 so as to be able to run, and lower stage running section 24 engages with lower stage rail 22 so as to be able to run. Middle stage running section 23 further includes a drive source that generates power for running. As a result, arrangement direction moving section 2 is mounted on middle stage rail 21 and lower stage rail 22, and travels and moves in the arrangement direction.

[0040] Furthermore, arrangement direction moving unit 2 is provided with non-contact power receiving unit 25 at a height position between middle stage running unit 23 and lower stage running unit 24, at a height position that does not impede replacement of tape feeders 8. Non-contact power receiving unit 25 receives power in a non-contact manner from non-contact power transmitting units provided at corresponding heights of the plurality of substrate-related operating devices.

[0041] The arrangement direction moving unit 2 has a lifting drive unit 26 and the replacement unit 3 inside the box shape. The lifting drive unit 26 drives the replacement unit 3 to lift and lower from the height of the component supply unit 9A to the height of the spare feeder storage unit 9B. An example of the lifting drive unit 26 is a ball screw feed mechanism, but is not limited to this. FIG. 4 is a perspective view showing the internal configuration of the replacement unit 3. In FIG. 4, the side plate on the front side of the case 31 and the like are omitted.

[0042] The replacement unit 3 comprises a case 31, two attachment / detachment direction moving units 32, and two attachment / detachment direction drive devices 4. The case 31 has an opening 311 on the front side through which four adjacently arranged standard tape feeders 8X can be inserted and removed while lined up. The case 31 further has an internal space capable of accommodating four standard tape feeders 8X. Four slots 314 formed parallel to each other at a predetermined pitch Ps are engraved on the bottom plate 313 of the case 31. Furthermore, guide rollers 315 are disposed in front of each of the slots 314 on the bottom plate 313. As a result, the tape feeders 8 are inserted and removed via the opening 311 and the guide rollers 315 while the protrusions 88 are guided by the slots 314.

[0043] The two attachment / detachment direction moving parts 32 are provided so as to be movable in the attachment / detachment direction independently of each other with respect to the arrangement direction moving part 2. The two attachment / detachment direction moving parts 32 are provided inside the case 31 and arranged separately in the arrangement direction. The attachment / detachment direction moving part 32 has a holding surface 33 on the upper front side and an abutment surface 34 on the lower front side. The attachment / detachment direction moving part 32 holds the holding plate 8N on the upper rear surface of the tape feeder 8 with the holding surface 33. At this time, the abutment surface 34 abuts against the lower rear surface of the tape feeder 8. It is also possible to provide a connector on the abutment surface 34 and connect it to the feeder control part 87 of the tape feeder 8.

[0044] In order to supply power to the moving attachment / detachment direction moving part 32, a flexible power cable 35 is installed above the attachment / detachment direction moving part 32. The power cable 35 is connected to a power terminal 36 at the top of the attachment / detachment direction moving part 32.

[0045] The attachment / detachment direction drive device 4 moves the two attachment / detachment direction moving parts 32 in the attachment / detachment direction independently of each other. A attachment / detachment direction drive device 4 is provided for each attachment / detachment direction moving part 32. The attachment / detachment direction drive device 4 is composed of an upper rail 41, a lower rail 42, a drive motor 43, a fixed pulley 44, a drive belt 45, etc. Fig. 3 shows the attachment / detachment direction drive device 4 that drives the attachment / detachment direction moving part 32 on the back side of the page.

[0046] The upper rail 41 and the lower rail 42 are provided on the side plate 312 of the case 31. The upper rail 41 and the lower rail 42 are parallel to each other while being vertically spaced apart, and extend in the attachment / detachment direction. The drive motor 43 is disposed in the rear part of the case 31. A reduction gear mechanism is attached to the output shaft protruding from the drive motor 43 toward the back of the page. The fixed pulley 44 is disposed in front of the side plate 312. The annular drive belt 45 is hung horizontally between the output part of the reduction gear mechanism and the fixed pulley 44, and is rotatable.

[0047] The attachment / detachment direction moving part 32 is mounted on an upper rail 41 and a lower rail 42. The attachment / detachment direction moving part 32 is driven by the rotation of a drive belt 45 and moves in the attachment / detachment direction in the internal space of the exchange part 3. The attachment / detachment direction drive device 4 moves the tape feeder 8 held on the holding surface 33 and the attachment / detachment direction moving part 32 together. Naturally, the attachment / detachment direction drive device 4 can also move only the attachment / detachment direction moving part 32.

[0048] The attachment / detachment direction drive device 4 that drives the attachment / detachment direction moving part 32 on the front side of the page has the same configuration as described above, but the positions of the components are different. That is, the drive motor 47 is provided at a higher position than the drive motor 43 and facing in the opposite direction. Also, as shown in Fig. 9, the fixed pulley 48 and drive belt 49 provided on the side plate (not shown) on the front side of the page are also provided at a correspondingly high position. By thus providing the two attachment / detachment direction drive devices 4 facing in the opposite direction at different heights, the replacement part 3 and the arrangement direction moving part 2 can be made thinner.

[0049] The internal configuration of the detachable direction moving section 32 will be further described. Each of the two detachable direction moving sections 32 is provided with two sets of combinations of a holding section 5, a releasing section 6, a common driving section 7, and a control section 79. The two sets have the same configuration, are arranged side by side in the arrangement direction, and operate independently of each other. The configuration of one set will be described in detail below. The holding section 5, the releasing section 6, the common driving section 7, and the control section 79 are attached to a main body section 37 that is part of the detachable direction moving section 32 and extends in the vertical direction.

[0050] The common driving unit 7 operates the holding unit 5 and the releasing unit 6. As shown in Fig. 3, the common driving unit 7 is composed of a stepping motor 71, a first gear 73, a second gear 76, and a swinging member 77. The stepping motor 71 is fixed to the lower part of the main body 37. The stepping motor 71 switches between forward and reverse rotation in accordance with a command from the control unit 79, and rotates by the commanded rotation amount. An output gear 72 with a small number of teeth is provided on the output shaft of the stepping motor 71.

[0051] The first gear 73 is disposed above the stepping motor 71 and rotatably supported by the main body 37. The first gear 73 is configured by stacking a large gear 74 having a relatively large number of teeth and a small gear 75 having a relatively small number of teeth integrally on the same axis. In FIG. 4, the small gear 75 is located behind the large gear 74 and cannot be seen. The large gear 74 meshes with the output gear 72.

[0052] The second gear 76 is disposed above the first gear 73 and rotatably supported by the main body 37. The second gear 76 has more teeth than the pinion 75 and meshes with the pinion 75. A swinging member 77 is provided near the upper part of the second gear 76. The swinging member 77 has a swinging pin 78 at a position outside the outer periphery of the second gear 76. The output gear 72, the first gear 73, and the second gear 76 constitute a reduction mechanism. As a result, the forward and reverse rotations of the stepping motor 71 are converted into swinging of the swinging pin 78 in the attachment / detachment direction.

[0053] The release unit 6 can release the locking unit 8C that prevents the removal of the tape feeder 8 provided in the component supply unit 9A. The release unit 6 is composed of a directly acting member 61, a manual lever 67, and the like. The directly acting member 61 is a rod-shaped member that is long in the attachment / detachment direction. The directly acting member 61 has a long hole 62 that is long in the vertical direction at approximately the middle position in the longitudinal direction. A swing pin 78 is loosely fitted into this long hole 62. Therefore, the swinging motion of the swing pin 78 that describes an arc is converted into a linear motion of the directly acting member 61 in the attachment / detachment direction. The directly acting member 61 also has a release operation unit 63 at its front tip that releases the locking unit 8C.

[0054] Furthermore, the directly acting member 61 has intermediate drive pins 64 at the front and rear of the elongated hole 62. The two intermediate drive pins 64 are loosely fitted into elongated holes 53 of the slide plate 51, which will be described later. This maintains the directly acting member 61 in a horizontal state. Furthermore, the directly acting member 61 has indirect drive protrusions 65 on both the upper and lower side surfaces between the front intermediate drive pin 64 and the release operation portion 63. The pair of upper and lower indirect drive protrusions 65 drive the chuck 55 of the holding portion 5, which will be described later.

[0055] The manual lever 67 stands upward from the rear end of the directly operating member 61. The manual lever 67 is operated in the attachment / detachment direction by an operator, and enables manual operation of the directly operating member 61 when the common drive unit 7 is malfunctioning, etc. A position marker 68 is provided below the manual lever 67. The position marker 68 operates integrally with the directly operating member 61 to indicate the position of the directly operating member 61. The main body 37 is provided with a reference position sensor 6A and a holding position sensor 6B that detect the position marker 68.

[0056] 3 shows an initial state in which the holding unit 5 and the releasing unit 6 are not operating. The reference position sensor 6A detects the position marker 68 at the rear end position of the directly operating member 61, which corresponds to the initial state. The holding position sensor 6B detects the position marker 68 at the front end position of the directly operating member 61, which corresponds to the holding state when the holding unit 5 and the releasing unit 6 are operated (see FIG. 5). The reference position sensor 6A and the holding position sensor 6B output the detection results to the control unit 79.

[0057] The holding portion 5 can hold the tape feeder 8 to be replaced. The two holding portions 5 share the holding surface 33. Each holding portion 5 is composed of a slide plate 51 and a pair of upper and lower chucks 55. The slide plate 51 is a generally rectangular plate-shaped member, and is provided with a trapezoidal cutout hole. The slide plate 51 is biased forward by a biasing spring (not shown). A swinging member 77 swings in the cutout hole of the slide plate 51. The slide plate 51 is provided with four elongated slide holes 52 that are long in the attachment / detachment direction. A support pin 38 erected on the main body portion 37 is loosely fitted into each of the slide holes 52. The slide plate 51 is also provided with two elongated holes 53 that are long in the attachment / detachment direction. An intermediate drive pin 64 is loosely fitted into each of the elongated holes 53.

[0058] The play dimension of the long hole 53 in the attachment / detachment direction is larger than the play dimension of the slide hole 52 in the attachment / detachment direction. The sum of the play dimension of the slide hole 52 in the attachment / detachment direction and the play dimension of the long hole 53 in the attachment / detachment direction corresponds to a predetermined operating stroke length for the direct operating member 61 to operate in the attachment / detachment direction. In the initial state shown in Fig. 3, the intermediate drive pin 64 is in contact with the rear edge of the long hole 53, preventing the forward movement of the slide plate 51 biased forward. At this time, the slide plate 51 is in a retreated position where the support pin 38 is in contact with the front edge of the slide hole 52.

[0059] Chuck support seats 54 are provided at two locations near the front of the slide plate 51, which are vertically symmetrical with respect to the directly operating member 61. A pair of upper and lower chucks 55 are supported on the chuck support seats 54 so that they can swing. The pair of upper and lower chucks 55 have parallel portions at their rear sides that are roughly parallel to each other, approaching portions at their front sides, and bent portions at their front sides that bend away from each other. The chucks 55 are supported near the boundary between the parallel portions and the approaching portions.

[0060] The indirect drive projections 65 of the directly operating member 61 slide on the opposing surfaces of the pair of upper and lower chucks 55. In Fig. 3, the indirect drive projections 65 are in sliding contact with the rear ends of the parallel parts of the chucks 55. At this time, the pair of upper and lower chucks 55 are in a closed state with the approaching parts in contact with the directly operating member 61. The bent parts of the pair of upper and lower chucks 55 sandwich the release operation part 63 of the directly operating member 61 and are closed smaller than the holding hole 8P of the tape feeder 8.

[0061] The control unit 79 is disposed below the main body unit 37. The control unit 79 controls the direction and amount of rotation of the stepping motor 71 based on the detection results of the reference position sensor 6A and the holding position sensor 6B. Since the amount of rotation of the stepping motor 71 is controllable, the reference position sensor 6A and the holding position sensor 6B are not essential. However, when the power supply to the exchange device 1 is stopped or when an operation is performed by the manual lever 67, there is a risk that the position of the direct operating member 61 becomes unclear. Therefore, it is preferable to provide at least one of the reference position sensor 6A and the holding position sensor 6B.

[0062] Next, Fig. 5 is a partially enlarged perspective view showing the vicinity of the holding surfaces 33 of the two attachment / detachment direction moving parts 32 lined up and enlarged. Fig. 5 shows a holding state in which the holding part 5 and the releasing part 6 have been operated. As will be described in detail later, a pair of upper and lower chucks 55 of the holding part 5 protrude from the holding surface 33 and perform an opening operation to hold the tape feeder 8. In addition, the release operation part 63 at the tip of the direct operating member 61 of the releasing part 6 protrudes from the holding surface 33 and releases the lock part 8C of the tape feeder 8.

[0063] As shown in the figure, the two attachment / detachment direction moving sections 32 are provided adjacent to each other in the arrangement direction at a pitch three times the predetermined pitch Ps. The two attachment / detachment direction moving sections 32 may be provided adjacent to each other at a pitch twice the predetermined pitch Ps or at a pitch that is an integer multiple of four or more times the predetermined pitch Ps. In each attachment / detachment direction moving section 32, the two holding sections 5 are provided adjacent to each other in the arrangement direction at the predetermined pitch Ps. The two holding sections 5 may be provided adjacent to each other at a pitch that is an integer multiple of two or more times the predetermined pitch Ps.

[0064] 4. Holding Operation of Exchange Device 1 of the Embodiment Here, the differences in the holding methods of the multiple types of tape feeders (8X, 8Y, 8Z) with different width dimensions among the operations of the exchanging device 1 of the embodiment will be described. Fig. 6 is a plan view showing a typical holding method of the standard tape feeder 8X and the large tape feeder 8Y. As shown in the attachment / detachment direction moving part 32 on the upper side of the page of Fig. 6, each holding part 5 holds the standard tape feeder 8X.

[0065] 6, the large tape feeder 8Y faces two holding portions (5Y, 5) in the arrangement direction. Therefore, one holding portion 5Y holds the large tape feeder 8Y, while the other holding portion 5 maintains its initial state in which it does not protrude from the holding surface 33. This means that the other holding portion 5 does not get in the way when holding the large tape feeder 8Y.

[0066] Next, FIG. 7 is a plan view showing a typical holding method of the extra-large tape feeder 8Z. As shown in the figure, the extra-large tape feeder 8Z faces two attachment / detachment direction moving parts (32Z, 32) in the arrangement direction. Therefore, one holding part 5Z of one attachment / detachment direction moving part 32Z on the upper side of the paper holds the extra-large tape feeder 8Z, and the other holding part 5 maintains the initial state in which it does not protrude from the holding surface 33. In addition, the other attachment / detachment direction moving part 32 on the lower side of the paper maintains the two holding parts 5 in the initial state. In addition, the other attachment / detachment direction moving part 32 is maintained behind the one attachment / detachment direction moving part 32Z in the attachment / detachment direction by the attachment / detachment direction drive device 4. Usually, the other attachment / detachment direction moving part 32 remains at the rear end position in the attachment / detachment direction. According to this, when holding the extra-large tape feeder 8Z, the other holding part 5 and the other attachment / detachment direction moving part 32 do not get in the way. As described above, the holding portion 5 can hold the tape feeders (8X, 8Y, 8Z) regardless of their sizes.

[0067] Next, a detailed description will be given of the holding operation of the replacement device 1 of the embodiment for holding the tape feeder 8. The following description is common regardless of whether the tape feeder 8 to be held is located in the feeder storage device 96, the component supply unit 9A, or the spare feeder storage unit 9B. First, the arrangement direction drive device 20 moves the arrangement direction moving unit 2 to the front of the tape feeder 8 to be held. Next, the elevation drive unit 26 adjusts the height of the replacement unit 3 to the tape feeder 8. Next, the attachment / detachment direction drive device 4 advances the attachment / detachment direction moving unit 32 facing the tape feeder 8 in the attachment / detachment direction. The attachment / detachment direction moving unit 32 advances until the holding surface 33 abuts against the holding plate 8N of the tape feeder 8. At this point, the state shown in FIG. 3 is reached.

[0068] 3, the holding portion 5 and the releasing portion 6 do not protrude from the holding surface 33 in the initial state in which they are not operating. Therefore, even if the arrangement direction moving portion 2 moves slightly in the arrangement direction to fine-tune the position of the attachment / detachment direction moving portion 32, there is no risk of damaging the tape feeder 8. If the direct operating member 61 or the chuck 55 were in a state in which they protrude from the holding surface 33, it would be necessary to once retract the attachment / detachment direction moving portion 32 before the arrangement direction moving portion 2 moves, making the operation complicated and inefficient.

[0069] Next, the control unit 79 starts the stepping motor 71. As a result, the second gear 76 and the swinging member 77 start to rotate clockwise in FIG. 3, and the directly acting member 61 starts to advance in the attachment / detachment direction. As the intermediate drive pin 64 of the directly acting member 61 advances, the slide plate 51 is also biased and starts to advance. Thereafter, the slide plate 51 advances to an advanced position where the support pin 38 contacts the rear edge of the slide hole 52. As a result, both the directly acting member 61 and the chuck 55 in the closed state protrude from the holding surface 33 and enter the holding hole 8P.

[0070] When the direct operating member 61 further advances after the slide plate 51 stops at the forward position, the indirect driving projection 65 reaches the approaching portion of the chuck 55. Thereafter, the indirect driving projection 65 pushes and spreads the approaching portions of the pair of upper and lower chucks 55 to open the chucks 55. Then, as shown in FIG. 8, the pair of upper and lower chucks 55 are in a state where the bent portions are open, and grip the inner surface of the holding plate 8N. FIG. 8 is a side view of the attachment / detachment direction moving unit 32 showing a holding state in which the holding unit 5 and the release unit 6 have operated. The attachment / detachment direction moving unit 32 holds the tape feeder 8 using the pair of upper and lower chucks 55 of the holding unit 5. Note that in the holding state, there may be some play between the chuck 55 and the holding plate 8N.

[0071] When the direct action member 61 finishes moving forward by a predetermined stroke length, the release operation unit 63 pushes the release arm 8J forward. This causes the lock unit 8C to transition to a release state. Next, the attachment / detachment direction drive device 4 retracts the attachment / detachment direction moving unit 32 holding the tape feeder 8. At this time, the tape feeder 8 slides while the protrusion 88 on the bottom surface is guided by the slot 314 of the bottom plate 313, and is accommodated in the internal space of the replacement unit 3. FIG. 9 is a perspective view showing a state in which the replacement unit 3 accommodates the tape feeder 8. In FIG. 9, the case 31 constituting the replacement unit 3 is omitted. In another embodiment, the replacement unit 3 may not have the slot 314 of the bottom plate 313, and the tape feeder 8 may be supported only by the holding unit 5.

[0072] When storing the tape feeder 8, the attachment / detachment direction moving section 32 pulls out the tape feeder 8 horizontally in the attachment / detachment direction. The pulling force at this time acts on the tape feeder 8 from the chuck 55. And because the chuck 55 is at the same height as the connector 8B, the connector 8B is pulled out straight. This reduces the risk of damage to the connector 8B. Similarly, the upper positioning pin 89 and the lower positioning pin 8A are hardly subjected to a diagonal pulling force, so the risk of damage is also reduced. In addition, only a small pulling force is required.

[0073] Thereafter, the replacement unit 3 is driven to the front of either the feeder storage device 96, the component supply unit 9A, or the spare feeder storage unit 9B. The replacement unit 3 can then store or load the accommodated tape feeder 8 in any of the slots. The storing and loading operations of the tape feeder 8 are performed in roughly the reverse order of the holding operations described above.

[0074] 5. Example of procedure for exchange operation of exchange device 1 of embodiment Next, an example of a procedure for an exchange operation when the exchange device 1 of the embodiment exchanges the tape feeder 8 of the component supply unit 9A will be described. In the following, an example of a procedure for exchanging the standard first tape feeder 8X1 and third tape feeder 8X3 provided adjacent to the component supply unit 9A with the prepared second tape feeder 8X2 and fourth tape feeder 8X4 will be described.

[0075] Fig. 10 is a plan view of the replacing unit 3, showing a schematic state immediately before the start of the retrieval operation in an example of the replacing operation procedure. Fig. 11 is a plan view of the replacing unit 3, showing a schematic state after the retrieval operation has been completed. Fig. 12 is a plan view of the replacing unit 3, showing a schematic state immediately before the start of the installation operation. Fig. 13 is a plan view of the replacing unit 3, showing a schematic state after the installation operation has been completed. In Figs. 10 to 13, the second tape feeder 8X2 and the fourth tape feeder 8X4 are shown hatched for the sake of convenience.

[0076] The exchange device 1 first puts the two holding parts 5 of one of the attachment / detachment direction moving parts 32 (upper side of the paper in FIG. 10) in a state where they do not hold any tape feeders 8. The exchange device 1 then puts the two holding parts 5 of another attachment / detachment direction moving part 32 (lower side of the paper in FIG. 10) in a state where they hold the second tape feeder 8X2 and the fourth tape feeder 8X4 and house them in the exchange unit 3. Next, the arrangement direction driving device 20 and the lifting driving part 26 operate to bring one attachment / detachment direction moving part 32 of the exchange unit 3 directly opposite the first tape feeder 8X1 and the third tape feeder 8X3 of the component supply unit 9A.

[0077] Next, one of the attachment / detachment direction moving sections 32 is driven by the attachment / detachment direction drive device 4 to move forward (see arrow M1 in FIG. 10). Next, in one of the attachment / detachment direction moving sections 32, the common drive section 7 operates and the two holding sections 5 hold the first tape feeder 8X1 and the third tape feeder 8X3, resulting in the state shown in FIG. 10. Next, one of the attachment / detachment direction moving sections 32 is driven by the attachment / detachment direction drive device 4 to move backward (see arrow M2 in FIG. 11). As a result, the first tape feeder 8X1 and the third tape feeder 8X3 are collected and stored in the replacing section 3, as shown in FIG. 11.

[0078] Next, the arrangement direction moving section 2 moves in the arrangement direction by three times the predetermined pitch Ps (see arrow M3 in FIG. 12). Then, as shown in FIG. 12, the other installation / removal direction moving section 32 faces the vacant slot. Next, the other installation / removal direction moving section 32 is driven by the installation / removal direction drive device 4 to move forward (see arrow M4 in FIG. 13) and reaches the state shown in FIG. 13. Next, the holding section 5 of the other installation / removal direction moving section 32 releases its holding in accordance with the operation of the common drive section 7 in the opposite direction. In addition, the release section 6 sets the lock section 8C to the locked state. As a result, the second tape feeder 8X2 and the fourth tape feeder 8X4 are mounted on the component supply section 9A. Thereafter, the other installation / removal direction moving section 32 is driven by the installation / removal direction drive device 4 to move backward, and the replacement operation is completed.

[0079] It should be noted that an exchange operation is also possible in which the first tape feeder 8X1 is collected by one of the holding parts 5 of one of the attachment / detachment direction moving parts 32, and the second tape feeder 8X2 is installed by one of the holding parts 5 of another attachment / detachment direction moving part 32. Furthermore, it is also possible to use a total of four holding parts 5 to collect four tape feeders 8X together, and then install four tape feeders 8X together. The exchange device 1 can perform various other exchange operation methods.

[0080] The exchanging device 1 of the embodiment is provided with a plurality of holding units 5, and therefore can handle a plurality of tape feeders (8, 8X, 8Y) at the same time. This allows the exchanging device 1 to efficiently perform exchanging operations such as component resupply operations when components run out during mounting operations, and setup changes when switching the type of board to be produced. Therefore, compared to a conventional configuration provided with one holding unit 5, the non-productive time required for exchanging the tape feeders (8, 8X, 8Y) is reduced, and the proportion of the production time of the component mounting device (93, 94, 95) is increased, improving the production efficiency of the board.

[0081] 6. Applications and Modifications of the Embodiments The exchange device 1 may include three or more detachable direction moving parts 32. The exchange device 1 may include three or more holding parts 5 in the detachable direction moving part 32. The number and arrangement pitch of the holding parts 5 may differ depending on the detachable direction moving part 32. The arrangement pitch of the holding parts 5 may not be an integer multiple of the arrangement pitch Ps of the tape feeders 8. The exchange device 1 of the embodiment includes four holding parts 5, but as shown in FIG. 14 and FIG. 15, the number of holding parts 5 may be reduced to two for simplification. FIG. 14 is a conceptual diagram showing an exchange device 11 of a first application example that is a simplification of the exchange device 1 of the embodiment. In the exchange device 11 of the first application example, one holding part 5 is provided on each of the two detachable direction moving parts 32.

[0082] In the exchanging device 11 of the first application example, when the first tape feeder 8X1 equipped in the component supply unit 9A is replaced with a prepared second tape feeder, one of the mounting / removing direction moving units 32 recovers the first tape feeder 8X1, and another mounting / removing direction moving unit 32 installs the second tape feeder 8X2. The exchanging device 11 can also recover two tape feeders 8X together, or install two tape feeders 8X together. Furthermore, when replacing a large tape feeder 8Y, the holding unit 5 of one of the mounting / removing direction moving units 32 of the exchanging device 11 holds the large tape feeder 8Y, and the other mounting / removing direction moving unit 32 is maintained behind the one mounting / removing direction moving unit 32 in the mounting / removing direction by the mounting / removing direction drive unit 4.

[0083] 15 is a conceptual diagram of an exchanging device 12 of a second applied example that is a simplification of the exchanging device 1 of the embodiment. In the exchanging device 12 of the second applied example, two holding units 5 are provided on one attachment / detachment direction moving unit 32. The exchanging device 12 of the second applied example can collect two tape feeders 8X together or can install two tape feeders 8X together, in addition to the exchanging operation of recovering a first tape feeder 8X1 with one holding unit 5 and mounting a second tape feeder 8X2 with another holding unit 5. Furthermore, when replacing a large tape feeder 8Y, one holding unit 5 of the exchanging device 12 holds the large tape feeder 8Y, and the other holding unit 5 maintains the initial state.

[0084] Furthermore, instead of the chuck 55 that grips the tape feeder 8 in the holding unit 5, a hook that catches and pulls out the tape feeder 8, an electromagnet that magnetically attracts the tape feeder 8, or the like may be used. Also, as an exchange device that does not have the lifting and lowering drive unit 26, the tape feeder 8 may be exchanged only between the component supply unit 9A and the feeder storage device 96. Furthermore, the tape feeder 8 may be configured so that the tape reel TR can be taken out to the rear side, and the exchange device (1, 11, 12) may exchange only the tape reel TR as the exchange element. Various other applications and modifications of this embodiment are possible. [Explanation of symbols]
