  Next, embodiments of the present invention will be described with reference to the drawings. First, the configuration of the component mounting apparatus 1 will be described with reference to FIGS. In FIG. 1, a substrate transport mechanism 2 is disposed in the X direction (substrate transport direction) on the upper surface of a base 1a. The substrate transport mechanism 2 transports a substrate 3 as a component mounting target, and It is positioned and held at the work position by the component mounting mechanism described. Component supply units 4A and 4B for supplying components to be mounted on the substrate 3 are disposed on both sides of the substrate transport mechanism 2, and a tray feeder 5 is provided in the component supply unit 4A, and a component supply unit 4B is provided in the component supply unit 4B. A plurality of tape feeders 13 are arranged.

  The tray feeder 5 supplies the tray 6 in which the components 60 are stored in a grid arrangement to the component extraction position by the component mounting mechanism. As a result, the component 60 held on the tray 6 is sent to the pickup position by the mounting head of the component mounting mechanism. The tape feeder 13 feeds the components to the component mounting mechanism by pitch-feeding the carrier tape holding the components.

  A Y-axis moving table 7 driven by a linear motor is disposed in the Y direction at one end of the base 1a in the X direction. The Y-axis moving table 7 includes two X-axis moving tables 8A and 8B. Corresponding to the component supply unit 4A and the component supply unit 4B, they are coupled to be movable in the Y direction. Mounting heads 9A and 9B are mounted on the X-axis moving tables 8A and 8B so as to be movable in the X direction by a linear drive mechanism. Each of the mounting heads 9A and 9B is a multiple head having a plurality of unit transfer heads 10, and a suction nozzle 10a (see FIG. 2) is replaceably attached to the lower end of each unit transfer head 10.

  By driving the Y-axis moving table 7 and the X-axis moving table 8A, the mounting head 9A moves horizontally between the component supply unit 4A and the substrate 3 held by the substrate transport mechanism 2, and is stored in the tray 6. The component 60 is picked up by being sucked and held by the sucking nozzle 10 a and mounted on the substrate 3. By driving the Y-axis moving table 7 and the X-axis moving table 8B, the mounting head 9B moves horizontally between the component supply unit 4B and the substrate 3, and picks up the components from the carrier tape pitch-fed by the tape feeder 13. The nozzle 10a is sucked and held and mounted on the take-out substrate 3. Therefore, the Y-axis movement table 7, the X-axis movement tables 8A and 8B, and the mounting heads 9A and 9B constitute a component mounting mechanism that mounts the substrate 3 by sucking and holding the components by the suction nozzle 10a of the unit transfer head 10.

  The mounting heads 9A and 9B are provided with a substrate recognition camera 11 that is located on the lower surface side of the X-axis moving tables 8A and 8B and moves integrally with the mounting heads 9A and 9B. The substrate recognition camera 11 moves integrally with the mounting heads 9A and 9B above the substrate 3, and the substrate 3 is imaged by the substrate recognition camera 11 so that the position of the substrate 3 is recognized. A component recognition camera 12 is disposed between the component supply units 4A and 4B and the substrate transport mechanism 2. When the mounting heads 9A and 9B holding the electronic components move above the component recognition camera 12, the component recognition camera 12 images these electronic components and performs recognition processing on the imaging results, thereby mounting heads 9A and 9B. In this state, the electronic component is identified and recognized.

  FIG. 2 shows a state in which the tray feeder 5 is set in the component supply unit 4A. The tray feeder 5 includes a base portion 20 that is movable on a work floor by wheels 21. On the upper surface of the base portion 20, a feeder main body portion 22 containing a magazine 23 is disposed on the side operated by the operator OP, and the magazine 23 has a plurality of rectangular plate-like pallets 24 each stored in a pallet storage portion 23 a. Stored. On the front side of the magazine 23 (on the component mounting apparatus 1 side), the pallet holding unit 25 that pulls out and holds the pallet 24 from the pallet storage unit 23a and the pallet holding unit 25 are moved up and down (arrow a). A holding unit elevating mechanism 26 that is positioned at the height position is provided.

  On the pallet 24, the tray 6 in which the components 60 are stored in a lattice arrangement is held in a state where the tray 6 is positioned at a predetermined position (see FIG. 4A), and the tray 6 held on the pallet 24 is stored in the magazine 23. It is stored in each pallet storage part 23a. In the component mounting operation by the component mounting apparatus 1, the pallet 24 is pulled out by the pallet holding unit 25 and moved to the component pick-up position P by the unit transfer head 10 of the mounting head 9A. Then, the mounting head 9A picking up the component 60 from the tray 6 in this state by the suction nozzle 10a moves to the substrate 3 positioned and held by the substrate transport mechanism 2 (arrow b), whereby the component 60 is mounted on the substrate 3. The

  This component mounting operation is controlled by the main body control device 14, and the movement operation of the pallet 24 in the tray feeder 5 is controlled by a feeder control unit 30 provided in the tray feeder 5. In the component supply unit 4A, an operation panel 15 is disposed at a position where the operator OP can easily see. By operating a touch panel switch provided on the display surface of the operation panel 15, the operation panel 15 is operated. In addition, necessary operation input can be made to the feeder control unit 30.

  In the feeder main body 22, a pallet placement unit 27 is provided in a region different from the pallet storage unit 23 a (here, above the uppermost pallet storage unit 23 a). On the pallet placing unit 27, a pallet 24 that holds the tray 6 that has run out of parts in the process of executing the component mounting work is placed for tray replacement. The upper surface side of the pallet placing part 27 is covered with the ceiling part of the feeder main body part 22, and the pallet to the pallet placing part 27 is located on the front side (operation side by the operator OP) of the ceiling part of the feeder main body part 22. An open / close cover 28 for allowing 24 to be carried in and out is provided to be openable and closable. The open / close cover 28 is closed during the component mounting operation.

  When the tray 6 held on the pallet 24 needs to be replaced during the component mounting operation, the pallet 24 is moved from the pallet holding unit 25 and mounted on the pallet mounting unit 27. Then, the operator OP opens the opening / closing cover 28 to carry out the pallet 24 from the pallet placing portion 27, and performs tray exchange for exchanging the empty tray 6 in which the parts are cut off with another tray 6. The pallet 24 after the tray replacement is carried in via the opening / closing cover 28, placed again on the pallet placing part 27, and further pulled out by the pallet holding part 25. In other words, a pallet 24 for holding a tray that has run out of parts is placed on the pallet placing portion 27, and the pallet 24 can be carried out of the feeder main body 22 for tray replacement. ing.

  Next, the detailed configuration of the tray feeder 5 will be described with reference to FIGS. In FIG. 3, a vertical frame 33 erected on the upper surface of the base portion 20 is provided with a holding portion elevating mechanism 26 configured to rotationally drive a feed screw 35 screwed to a nut member 36 by an elevating drive motor 34. A horizontal pallet holding plate 37 constituting the pallet holding part 25 is coupled to the nut member 36. By driving the raising / lowering drive motor 34, the pallet holding part 25 raises / lowers on the front side of the feeder main body part 22 (arrow d). At this time, by specifying the storage address assigned to each pallet storage part 23a, the pallet holding part 25 can be positioned at the height position of the pallet storage part 23a corresponding to this storage address.

  The pallet holding part 25 has a pallet slide function for performing a sliding operation for pulling out the pallet 24 from the pallet storage part 23 a and returning the drawn pallet 24 back to the pallet storage part 23 a. The pallet 24 can be slid along the upper surface of the pallet holding plate 37 by driving the slide drive motor 38 disposed on the side. That is, as shown in FIG. 4A, a slide guide 42 is disposed on the upper surface of the pallet holding plate 37 constituting the pallet holding portion 25 in the Y direction (direction in which the pallet holding portion 23a is in contact with or separated from). A slide member 41 is slidably fitted to the slide guide 42.

  The slide member 41 can reciprocate along the slide guide 42 by a moving mechanism (not shown) using a slide drive motor 38 as a drive source, and engages a locked portion 24 a provided at the front end of the pallet 24. The latching | locking part 41a which can be stopped is provided. The pallet 24 is stored in the pallet storage part 23a in a state of protruding in the pull-out direction so that the locked part 24a can be locked by the locking part 41a. Further, on the upper surface of the pallet holding plate 37, guide members 43 for guiding the movement of the pallet 24 in the Y direction are provided on both sides of the slide guide 42.

  By driving the slide drive motor 38, as shown in FIG. 4B, the slide member 41 moves in a direction approaching the pallet storage portion 23a (arrow e) and is locked by the locking portion 41a. The part 24a is locked. In this state, the slide drive motor 38 is driven to move the slide member 41 in a direction away from the pallet storage portion 23a, whereby the pallet 24 is moved by the slide member 41 to the pallet storage portion as shown in FIG. It is pulled out from 23a, moves onto the upper surface of the pallet holding plate 37, and moves while being guided on both sides by the guide member 43 (arrow f). The pallet holding / unloading by the pallet holding unit 25 is executed not only for the pallet storage unit 23a but also for the pallet placing unit 27.

  That is, the pallet holding part 25 is moved up and down by the holding part raising / lowering mechanism 26, whereby the pallet 24 is pulled out from the plurality of pallet storage parts 23a and moved to the part picking position P by the unit transfer head 10 of the mounting head 9A. Movement for placing the pallet 24 on the pallet placing portion 27 for tray replacement, and after supplying the parts, the pallet 24 after the tray replacement is returned to the pallet housing portion 23a having a predetermined storage address. It is possible to move to enter. Accordingly, the pallet holder 25 and the holder lifting mechanism 26 constitute a pallet moving mechanism that pulls the pallet 24 from the magazine 23 and moves it to the component pick-up position P.

  Next, the configuration of the pallet 24 and the tray 6 will be described with reference to FIGS. As shown in FIG. 5, a locked portion 24 a having a notch portion 24 b with which the locking portion 41 a is engaged is provided on one end surface of the pallet 24. Two rectangular rod-shaped fixed regulating members 50A are arranged in series in the X direction at a position adjacent to the locked portion 24a on the upper surface of the pallet 24. The restriction member 50A is fastened and fixed to fastening holes 24d formed at a plurality of positions on the pallet 24 by fastening bolts 51, and the fixing position of the restriction member 50A on the pallet 24 can be changed by selecting the position of the fastening hole 24d. It has become. Similarly, a rectangular bar-shaped movable restricting member 50B is paired with the restricting member 50A at a position facing each restricting member 50A in the Y direction. The regulating member 50B is fastened to a fastening long hole 24f formed in the Y direction on the pallet 24 so that the position in the Y direction can be adjusted by a fastening bolt 52, and a distance D1 between the opposing regulating member 50A and the regulating member 50B. Is adjustable.

  As shown in the AA cross section, a pair of restricting members 50A and 50B are arranged opposite to each other at a substantially central position in the Y direction of the pallet 24. The restriction member 50A is fastened and fixed to the fastening holes 24d formed at a plurality of positions by fastening bolts 51 in the same manner as the restriction member 50A described above, and the fixing position of the restriction member 50A on the pallet 24 can be changed. The regulating member 50B is fastened to a fastening long hole 24f formed in the X direction by a fastening bolt 52 so that the position in the X direction can be adjusted, and the distance D2 between the opposing regulating member 50A and the regulating member 50B can be adjusted. It has become. The height dimensions of the restriction member 50A and the restriction member 50B are set in accordance with dimensions that can support the tray 6 described below from below.

  As shown in FIG. 6, the tray 6 is a bottomless rectangular box-shaped member whose upper surface is opened by a flat plate-shaped component storage portion 6a, and is manufactured by molding a resin. The component storage portion 6a is formed with a plurality of cavities 6b for storing the components 60 in a predetermined lattice arrangement, and the tray 6 is a component storage as a flat portion in which a plurality of cavity portions 6b for storing the components 60 are recessed. It has the form which has the part 6a. The lower surface side of the cavity portion 6b is an embossed portion 6d which is an extended portion provided to extend downward from the component storage portion 6a, and the embossed portion 6d located at the outermost edge in the arrangement of these embossed portions 6d. The distance between the outer surfaces is d1 in the X direction and d2 in the Y direction.

  The edge part of the component storage part 6a is provided with a side wall part 6c extending downward, and the rigidity required for the tray 6 is secured by the box structure combining the component storage part 6a and the side wall part 6c. Yes. Here, since the tray 6 is made of a resin that is inferior in strength in terms of material, it has a characteristic that it has a low rigidity and is easily deformed compared to a metal tray conventionally used for this type of application. Have. That is, the tray 6 has the strength required to store and hold the component 60 in the cavity portion 6b, but the tray 6 is positioned outwardly to position and hold the tray 6 at a predetermined position on the pallet 24. Therefore, it does not have sufficient rigidity to secure a normal shape in a state of being sandwiched by the clamp mechanism.

  When the tray 6 having such strength characteristics is mounted and used on a conventional clamp-type pallet that holds the tray by being sandwiched from both sides, the tray itself is deformed and the position fixing state becomes unstable and stored. The component is not held in the correct position, causing a component adsorption error. In order to prevent such inconvenience, in the present embodiment, when the tray 6 manufactured by resin molding as shown in FIG. 6 and having low rigidity is targeted, the pallet 24 having the configuration shown in FIG. I use it. In this case, the distances D1 and D2 for determining the arrangement positions of the restricting members 50A and 50B are set corresponding to the distances d1 and d2 in the target tray 6. Thereby, the same pallet 24 can be shared by a plurality of types of trays 6 having different sizes, and a pallet with excellent versatility is realized.

  FIG. 7 shows a state in which the tray 6 is held on the pallet 24 in which the distances D1 and D2 are set in this way. That is, the tray 6 is aligned so that the four side walls 6c are positioned outside the regulating members 50A and 50B arranged in advance on the pallet 24, and the tray 6 is placed on the pallet 24. In this state, the lower surface side of the component storage portion 6a is supported by the regulating members 50A and 50B arranged in a frame shape on the four sides. Then, the side surfaces 50a and 50b of the regulating member 50A and the regulating member 50B are brought into contact with the side surface 6e of the embossed portion 6d at the outermost edge, whereby the horizontal position of the tray 6 on the pallet 24 is regulated. At this time, the distances D1 and D1 are set so that an excessive gap exceeding the positioning tolerance is not generated between the side surfaces 50a and 50b and the side surface 6e, and an appropriate gap that does not cause interference at the time of alignment is realized. Set D2.

  That is, the upper surface of the pallet 24 used in the tray feeder 5 of the present embodiment is an extending portion that supports the tray 6 from below and extends downward from the component storage portion 6a that is a flat portion. Restricting members 50A and 50B for restricting the horizontal position of the tray 6 by contacting the side surface 6e of the embossed portion 6d are disposed. In the tray setting method in which the tray 6 is set on the pallet 24, the tray 6 is supported from below by the regulating members 50A and 50B disposed on the top surface of the pallet 24, and extended downward from the component storage portion 6a. The position of the tray 6 in the pallet 24 in the horizontal direction is regulated by bringing the regulating members 50A and 50B into contact with the side surface 6e of the embossed part 6d.

  In the above-described embodiment, the example in which the embossed portion 6d located at the outermost edge is used as the extended portion provided to extend downward from the component storage portion 6a has been described. Is not limited, and any form may be used as long as it has a function of regulating the horizontal position of the tray 6 in combination with the regulating members 50A and 50B provided on the pallet 24.

  For example, FIG. 8 (a) uses two embossed portions 6d positioned adjacent to each other in the vicinity of the center of the tray 6 as the extending portion, and a regulating member 50C shaped to fit between these embossed portions 6d. The example provided in the corresponding position in the pallet 24 is shown. In this case, the horizontal position of the tray 6 is regulated by bringing the side surface of the regulating member 50C into contact with the side surface 6e of the embossed portion 6d.

  8B, the side wall portions 6c of the four sides of the tray 6 are used as the extending portions, and the regulating members 50D that are in contact with the side surfaces 6f of the side wall portions 6c are provided at corresponding positions on the pallet 24. An example is shown. In this case, the horizontal position of the tray 6 is regulated by bringing the side surface 50d of the regulating member 50D into contact with the side surface 6f of the side wall portion 6c.

  Further, FIG. 8 (c) uses a positioning pin 53 projecting downward from the component storage portion 6a as an extending portion, and a regulating member provided with a fitting hole 50e into which the positioning pin 53 is fitted. An example in which 50E is provided at a position corresponding to the alignment pin 53 in the pallet 24 is shown. In this case, the horizontal position of the tray 6 is regulated by bringing the inner peripheral surface of the fitting hole 50 e into contact with the outer peripheral surface 53 a of the alignment pin 53.

  When the arrangement of the cavity portions 6b in the tray 6 is asymmetric in the front-rear direction, or when the component 60 to be stored is a polar component whose mounting direction is specified, the tray 6 is set on the pallet 24. At this time, the tray 6 must be checked after setting it. If the tray 6 is set in the wrong direction, the suction nozzle 10a cannot take out the component normally, or it is not mounted in the correct mounting direction when mounted on the board. This may cause mounting errors.

  In order to prevent such setting in the wrong direction, it is possible to prevent erroneous setting by using a pallet 24 as shown in FIG. In the pallet 24 shown in FIG. 9A, a protruding portion 54 is provided on the side surface of the regulating member 50B disposed on the rear side so as to protrude to the front side. FIG. 9B shows an example of the tray 6 set on the pallet 24 shown in FIG. In the middle of the two cavity portions 6b located at both front ends of the tray 6, an interference portion 6g protrudes downward from the component storage portion 6a. The tray 6 is asymmetric with respect to the center point CP in plan view. It has a shape.

  FIG. 10A shows a state in which such a tray 6 is set on the pallet 24. When the tray 6 is in the correct set state where the front-rear direction of the pallet 24 coincides with the front-rear direction of the pallet 24, as shown in FIG. 10B, both the protruding portion 54 and the interference portion 6g interfere with other parts. There is no occurrence, and the position of the tray 6 is correctly regulated by the regulating member 50A and the regulating member 50B. On the other hand, when the front and rear direction of the tray 6 does not coincide with the front and rear direction of the pallet 24 and is set in the reverse direction, the interference portion 6g interferes with the protruding portion 54 as shown in FIG. To do. For this reason, the operator cannot immediately set the tray 6 on the pallet 24, and immediately detects that the setting direction of the tray 6 is incorrect.

  That is, in the example shown in FIGS. 9 and 10, the tray 6 has an asymmetric shape with respect to the center point CP in plan view, and when the tray 6 is set in the wrong direction with respect to the pallet 24 on the regulating member 50 </ b> B. Only the protruding portion 54 is provided at a position causing interference with the interference portion 6 g of the tray 6. In the tray setting method in which the tray 6 having such a configuration is set on the pallet 24 having such a configuration, only when the tray 6 is set on the regulating member 50B in the wrong direction with respect to the pallet, Protruding portions 54 are provided at positions where interference occurs, thereby preventing the tray 6 from being set in the wrong direction with respect to the pallet 24.

  In the example shown in FIGS. 9 and 10, an erroneous set is detected by the interference between the protruding portion 54 provided on the regulating member 50B and the interference portion 6g protruding downward from the component storage portion 6a. Various variations are possible for the formation site and shape of the protrusion provided for detection purposes. That is, since various aspects of the asymmetrical shape of the tray 6 are assumed, depending on the aspect of the asymmetrical shape of the target tray 6, the portions of the tray 6 and the pallet 24 that interfere with each other only in the erroneous setting state are selected. What is necessary is just to make it provide the protrusion part according to the shape of the said site | part of the tray 6 in the site | part of the selected pallet 24. FIG.

  As described above, in the present embodiment, the tray 6 having the component storage portion 6a as a flat surface portion in which a plurality of cavity portions 6b for storing the components 60 are provided is supplied to the component extraction position by the component mounting mechanism. In the tray feeder 5, on the upper surface of the pallet 24 that positions and holds the tray 6 at a predetermined position, the tray 6 is supported from below and extended from the component storage portion 6a to the embossed portion 6d. In this configuration, a regulating member that abuts the side surface of the portion and regulates the horizontal position of the tray 6 is provided. As a result, it is possible to obtain a stable position fixing state even for a tray with low rigidity such as a resin molded product, and it is necessary to execute an existing tray clamp releasing operation and a new tray clamping operation every time the tray is replaced. Therefore, it is possible to reduce the operator's work load accompanying parts replenishment and improve the operating rate of the equipment.

  The tray feeder, tray set pallet, and tray setting method according to the present invention have the effect of reducing the work load of the worker accompanying the component replenishment and improving the operating rate of the equipment. This is useful in the field of component mounting.
