Disclosure of Invention

Technical problem

However, in recent years, in a Surface Mount Technology (SMT) process, as the productivity of equipment increases, the frequency of supplying electronic components during production increases, and there is an increasing demand for labor saving and component replenishment automation. This is partly due to, for example, an increase in the size of the in-vehicle connector component or the like, an increase in the size of the tray component due to the use of SMT for large components in post-processing, and a decrease in the number of components that can be supplied from one tray, resulting in an increase in the frequency of replenishing components on the tray. On the other hand, although it is necessary to increase the number of components to be mounted in order to save labor for component replenishment, it is impossible to simply enlarge the space of the component mounting apparatus from the viewpoint of area productivity. Furthermore, if the passage between the lines of the apparatus is greatly blocked in order to increase the storage capacity, this will adversely affect the operability and transportability.

The present disclosure has been made in view of the above-described circumstances in the prior art, and an object thereof is to provide a component storing device and a component mounting system capable of saving labor for tray replenishment, preventing a jump-out to a passage between lines, and expanding a storage capacity of a tray.

The present disclosure provides a component mounting system, comprising: a component mounting device configured to take out a component stored in the component storage body by the component mounting section and mount the component on the substrate; a component supply device configured to supply the component storage body to a position where the component is taken out by the component mounting section; and a component storing device configured to replenish the component storage body to the component supplying device, wherein the component storing device includes: a cartridge allowing insertion and removal of a component storage body having components stored therein along a first axis; a storage allowing the cartridges to be taken in and out along a second axis intersecting the first axis in a plane along the horizontal plane; and a component bank transfer section configured to transfer a component bank along a first axis from a cartridge stored in a storage including a housing forming an internal space capable of storing the cartridge, and the housing including an opening through which the cartridge is fed in and taken out along a second axis.

Advantageous effects of the invention

According to the present disclosure, a cartridge can be easily transferred using a compact apparatus, and area productivity can be improved while labor for tray replenishment can be saved.

Detailed Description

Hereinafter, embodiments of a component storing device and a component mounting system according to the present disclosure will be described in detail with reference to the accompanying drawings as appropriate. However, unnecessary detailed description may be omitted. For example, detailed descriptions of known matters and redundant descriptions of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy of the following description and to aid understanding by those skilled in the art. The figures and the following description are provided to enable those skilled in the art to fully understand the present disclosure and are not intended to limit the subject matter described in the claims.

Fig. 1 is a plan view of a factory floor on which a component mounting system 11 according to a first embodiment is provided. Hereinafter, in the figures of the arrow indicating directions, the X axis indicates the left-right direction of the component mounting device 13, the Y axis indicates the front-rear direction of the component mounting device 13, and the Z axis indicates the up-down direction of the component mounting device 13. The X-axis and the Y-axis are orthogonal to each other and contained in a horizontal plane. The Z-axis is contained in a vertical plane orthogonal to the horizontal plane.

As shown in fig. 1, on a factory floor, a plurality of component mounting devices 13 are arranged side by side so as to be close to each other along a passage 15 having a passage width W1. A plurality of parallel substrate conveyors 19 are provided on each of the plurality of component mounting devices 13, wherein the X-axis direction is the conveyance direction of the substrate 17. The bar feeder 21, the tray component supply device 23, the tape component supply device 25, and the like are integrally connected to the component mounting device 13.

The plurality of component mounting devices 13 arranged in parallel constitute a mounting line 27 on the factory floor. In particular, on a factory site where the production yield is large, a plurality of mounting wires 27 are disposed in parallel to each other across the passage 15 in the direction along the X-axis passing through the front and rear of the component mounting device 13. Among the plurality of component mounting devices 13 arranged in parallel, the component mounting devices 13 in which the tray component storing device 29 is integrally connected to the tray component supplying device 23 constitute the component mounting system 11.

In the component mounting system 11, since the longitudinal direction of the tray component storing device 29 is provided along the passage 15, the reduction ratio of the effective passage width W2 between the adjacent mounting lines 27 is minimized.

Fig. 2 is an overall configuration diagram of the component mounting system 11 shown in fig. 1. The component mounting system 11 according to the first embodiment includes: a component mounting device 13 that takes out a component 33 stored in a tray 31 (see fig. 4) by a mounting head 35 (see fig. 3) as a component mounting portion, and mounts the component 33 on a substrate 17; a tray member supply device 23 for supplying the tray 31 to a position where the member 33 can be taken out by the mounting head 35; and a tray member storing unit 29 that supplements the tray 31 in the tray member supplying unit 23.

The component mounting device 13 includes a component mounting device main body portion 37. The surface of the component mounting device main body portion 37 is connected to the tray component supply device 23 and the tape component supply device 25 on the passage side. The tray component storing device 29 is integrally connected to the component mounting device main body portion 37 via the tray component supplying device 23.

The tray component storage 29, which is an example of a component storage, includes a magazine 41, the magazine 41 allowing insertion and removal of a pallet 39 (see fig. 4) along a first axis (e.g., X-axis), on which the tray 31 of the storage component 33 (see fig. 4) is placed on the pallet 39. The tray member storage 29 includes a pallet storage section 43 serving as a storage. The pallet storage 43 allows the magazine 41 to be transferred in and out along a second axis (e.g., Y axis) intersecting the X axis in a plane along the horizontal plane. The tray component storage 29 includes a pallet conveying section 45. The pallet transfer section 45 transfers the pallet 39 along the X axis from the magazine 41 stored in the pallet storage section 43. The pallet 39 conveyed from the pallet storage unit 43 by the pallet conveying unit 45 is supplied to the pallet member supply device 23. Further, the pallet transfer section 45 transfers the pallet 39 from the pallet component supply device 23 to the pallet storage section 43 so as to collect the pallet 39 on which the components 33 are consumed (i.e., all the components 33 on the pallet 39 are used for mounting to the base plate 17).

Fig. 3 is a conceptual diagram showing a cross-sectional structure of the component mounting system 11 shown in fig. 2. In the component mounting apparatus main body portion 37, a substrate transfer portion 49 is provided on the upper surface of the base 47, and the substrate transfer portion 49 includes a substrate conveyor 19 that transfers the substrate 17 in a direction along the X-axis (substrate transfer direction). The substrate transfer section 49 transfers the substrate 17 to which the component is to be mounted, and positions and holds the substrate 17 at the operating position of the component mounting apparatus main body section 37. The tray member supply device 23 is provided on the passage side of the base 47.

The tray member supply device 23 includes a replacement pallet storage section 51. The replacement pallet storage section 51 is provided and holds a plurality of cartridges 41 in the up-down direction (direction along the Z axis). In the tray member supply device 23, a pallet replacer 53 is provided between the replacement pallet storage section 51 and the base 47. The pallet changer 53 moves up and down the changer lift table 55 by the pallet changer lift portion 57 (see fig. 11). The tray component supply device 23 moves the pallet 39 between the replacement pallet storage section 51 and the component taking-out position by operating the pallet replacement 53. The tray component supply device 23 supplies the components 33 to the mounting head 35 by moving the pallet 39 to the component take-out position, the pallet 39 having placed thereon the trays 31 (see fig. 4) storing the components 33 in a grid arrangement.

The mounting head 35 is a multi-type head including a plurality of unit transfer heads, and a suction nozzle is mounted on a lower end portion of each unit transfer head in a freely replaceable manner. The mounting head 35 is mounted movably in the X and Y directions by an XY stage 59, and the XY stage 59 includes a linear drive mechanism or the like and extends in a direction along the Y axis. The mounting head 35 is movable between a component taking-out position and a component mounting position on the substrate transfer section 49 by the XY stage 59.

The tray member storage device 29 includes a pallet storage section 43 and a pallet transfer section 45. The plurality of cartridges 41 are stored in the pallet storage section 43 at predetermined intervals in the up-down direction (direction along the Z axis). Any pallet 39 can be inserted and removed in the direction along the X axis by the pallet conveying part 45 from each magazine 41 stored in the up-down direction (direction along the Z axis). The pallet 39 extracted from the pallet storage unit 43 by the pallet transfer unit 45 is moved to the pallet member supply device 23 by the pallet transfer unit 45. Further, the pallet conveying part 45 also enables the pallet 39 to move in opposite directions.

Fig. 4 is a perspective view of a pallet 39 on which the tray 31 is placed. Fig. 5 is an exploded perspective view of the pallet 39 shown in fig. 4.

The pallet 39 will be described. The pallet body 61 of the pallet 39 is formed in a rectangular plate shape in a plan view. In the pallet 39, one of the pair of parallel long sides is a first long side 63 and the other is a second long side 65. In the first embodiment, the first long side 63 is the pallet front and the second long side 65 is the pallet back. One of the first long side 63 and the second long side 65 of the pallet 39 is conveyed toward the front end side in the conveying direction.

Including at least a portion of the upper surface of the pallet 39, is made of a magnetic material. A tray 31 made of a non-magnetic material such as resin is placed on the upper surface of the pallet 39. The plurality of members 33 are aligned in an aligned state on the tray 31. The tray 31 is held in a state of being positioned at a predetermined position of the pallet 39 by the positioning device 67. The pallet 39 on which the tray 31 is placed constitutes a component storage 69. The parts store 69 may be a parts store in which parts are placed on the pallet 39 and stored in the pallet 39. Further, by making the outer shape of the tray 31 similar to the outer shape of the pallet 39, the tray 31 can be used as the component storage 69.

Two tray positioning pieces 71, which are parallel to the first long side portion 63 and one short side portion adjacent to the first long side portion 63, respectively, are orthogonally fixed to the upper surface of the pallet 39. The two tray positioning pieces 71 are arranged in the orthogonal direction and include inner corners. One corner of the tray 31 is aligned with an inner corner of the pallet 39, and both side surfaces of the tray 31 are pressed against the tray positioning pieces 71, so that the tray 31 is positioned with respect to the pallet 39.

The pallet 31 on the pallet positioned in this way is fixed to the pallet 39 by pressing the positioning means 67 against the surface opposite to the surface pressed against the pallet positioning piece 71. The positioning means 67 comprise, for example, a magnet. The positioning device 67 is firmly fixed to the upper surface of the pallet 39 made of a magnetic material by magnetic force. Thus, the tray 31 is fixed while being restrained from moving on the pallet 39. At this time, the positioning device 67 includes two lever portions 73 (see fig. 5) at both end sides thereof, and each lever portion 73 is positioned above the upper surface of the pallet 39. The positioning device 67 can be easily removed from the pallet 39 by pressing the lever portion 73 toward the upper surface of the pallet 39 by the lever principle.

The first long side 63 of the pallet 39 is provided with a first joint 75 and the second long side 65 of the pallet 39 is provided with a second joint 77. The first engaging portion 75 and the second engaging portion 77 are arranged such that the opening sides of the engaging claws formed in a U-shape in a plan view face each other. The interval between the engagement claws of the first engagement portion 75 is larger than the interval between the engagement claws of the second engagement portion 77. In the first embodiment, the first engaging portion 75 is engaged with the replacement engaging lever 79 (see fig. 10) of the pallet replacement 53, and the second engaging portion 77 is engaged with the processor engaging lever 81 as the traction portion shown in fig. 10 of the pallet conveying portion 45.

Fig. 6 is a perspective view of a magazine 41 storing pallets 39. Fig. 7 is a perspective view of the cartridge 41 viewed obliquely from below.

The cartridge 41 will be described. The cartridge 41 is formed in a rectangular tubular shape in which upper ends of a pair of parallel side plates 83 are connected to each other by a top plate 85, lower ends of the pair of parallel side plates 83 are connected to each other by a bottom plate 87 (see fig. 7), and since insertion and removal openings 89 are provided on both sides, the internal storage space is opened. The magazine 41 is stored in the pallet storing section 43 such that both ends thereof in the direction along the X axis are open. In other words, a pair of side plates 83 are stored in the pallet storing section 43 in a spaced-apart manner in the direction along the Y axis.

The inner surface of each side plate 83 is provided with ribs 91, each of which includes both ends extending through the insertion and removal openings 89. Each of a pair of parallel short side portions of the pallet 39 is inserted into a gap between the ribs 91 adjacent to each other in the up-down direction (direction along the Z axis). Thus, in the internal storage space (see above), the magazine 41 stores the plurality of pallets 39 in a plurality of levels in the up-down direction (direction along the Z-axis), and allows the pallets 39 to be inserted into the insertion and removal openings 89 and removed from the insertion and removal openings 89.

As shown in fig. 6, a pair of X registration rollers 93 are provided on the lower side of the outer side of each side plate 83. Each of the pair of X alignment rollers 93 is rotatable about a rotation center perpendicular to the side plate 83. Further, on each side of the inner sides of the pair of side plates 83, Y alignment portions 95 are provided on the lower sides of the insertion and removal openings 89 near both ends. A tapered surface 97 is formed in the Y-alignment portion 95, and the tapered surface 97 is formed by an inclined surface in which the side plate 83 becomes thinner toward the lower side.

As shown in fig. 7, four Y-alignment rollers 99 are provided on the lower surface of the base plate 87. Each Y registration roller 99 is supported in such a manner as to be rotatable about a rotation center perpendicular to the placement piece 101 with respect to the placement piece 101 suspended from the lower surface of the bottom plate 87 in a direction perpendicular to the side plate 83. The X registration roller 93 and the Y registration roller 99 constitute a first registration group 103.

A pair of parallel opening lower side portions of the insertion and removal opening 89 at both ends of the bottom plate 87 serve as X alignment portions 105. The Y alignment portion 95 and the X alignment portion 105 including the tapered surface 97 constitute a second alignment group 107.

Fig. 8 is a perspective view of the tray member storage unit 29 shown in fig. 2. The pallet storing part 43 includes a housing (e.g., a cover 109) forming an inner space in which the magazine 41 can be stored. The cover 109 includes an opening (e.g., cartridge replacement window 111) through which the cartridge 41 can be introduced and removed along a second axis (Y-axis). The lower portion of the magazine replacement window 111 of the pallet storing section 43 serves as a base portion 113. The base portion 113 is provided with a docking portion 115. The docking portion 115 is, for example, a connection portion in the case of using a self-propelled cartridge transfer device (not shown). Since the docking portion 115 includes the connector 117, the docking portion 115 is electrically connected to the tray component storage controller 119 (see fig. 11). Further, an operation portion 121 such as a touch panel is provided on the outer surface of the path side of the pallet conveying portion 45, and the operation portion 121 is electrically connected to the pallet component storage controller 119 (see fig. 11). As the structure of the tray member storing device 29, the operation portion 121 may be omitted.

In the tray member storage device 29, a slide table device 123 is provided in the inner space of the cover 109. The cartridge 41 may be placed on the slide table device 123, and the slide table device 123 may move (i.e., send in and out) the cartridge 41 between the inner space of the cover 109 and the outside of the cover 109 by passing the cartridge 41 through the cartridge replacement window 111 along the second axis (Y axis).

Fig. 9 is a schematic configuration view of the inside of the tray member storing device 29 as seen from the passage side. The tray member storage device 29 includes a plurality of (e.g., four levels of) holders 125 spaced apart from each other in the up-down direction (direction along the Z-direction). Wherein, for example, the slide table device 123 is fixed to the second-stage mount 125 from the bottom. That is, in the pallet storing section 43, the second-stage magazine 41 from the bottom among the magazines 41 stored in the upper and lower four stages is placed on the slide table device 123. In the first embodiment, an example in which the slide table device 123 is disposed in the second hierarchy from the bottom will be described, and the slide table device 23 may be disposed in any hierarchy in the up-down direction. Further, in the first embodiment, an example will be described in which the slide table device 123 is provided only in the second hierarchy from the bottom, and the slide table device 23 may be provided in a plurality of hierarchies.

The slide table device 123 can manually drive the slide table 127 (see fig. 17) on which the magazine 41 is placed to advance and retreat. Further, the slide table device 123 may be configured such that the slide table 127 on which the cartridge 41 is placed automatically protrudes to the outside of the cover 109 by providing the advance-retreat driving portion 129. In this case, the advance and retreat driving portion 129 includes, for example, an air cylinder 131 (see fig. 18) as an advance and retreat driving source, a valve that supplies operation air to the air cylinder 131, and the like.

The pallet transfer section 45 provided in the pallet part storing device 29 includes a pallet processor 133 that moves the pallet 39 between the pallet storing section 43 and the pallet part feeding device 23. The pallet conveying section 45 includes a pallet processor lifting section 135 that moves up and down in the up-and-down direction (direction along the Z direction). The pallet processor elevation section 135 stands on the base section 113 and has substantially the same height as the pallet storage section 43. The pallet handler elevation 135 is provided with a vertical store feed screw (not shown). The accumulator feed screw is rotated by a processor lift motor (not shown). A lifting base nut portion (not shown) is screwed into the accumulator feed screw.

The lifting base 137 is fixed to the lifting base nut portion. The drawing device 141 is rotatably supported on the upper surface of the elevation base 137 along the Z-axis via the processor shaft 139. A processor motor 145 having an output shaft along the Z-axis is fixed to the upright base portion 143 of the elevation base 137. The belt 147 extends around the output shaft of the processor motor 145 and the processor shaft 139. The processor motor 145, belt 147 and processor shaft 139 form a rotation mechanism 149 (see fig. 10). When the processor motor 145 of the rotation mechanism 149 is driven, the rotational force is transmitted to the processor shaft 139, and the drawing device 141 rotates around the processor shaft 139. The drawing device 141 includes a processor engagement bar 81 and a pair of parallel pallet guides 151.

The pallet processor 133 moves up and down along the pallet storage section 43, for example, by driving a processor lift motor (not shown) by a pallet transfer controller 153 (see fig. 11). At this time, the pallet processor 133 may set the drawing device 141 at a height position of the pallet 39 corresponding to the storage address by designating the storage address of the pallet storage attached to the pallet storage 43. A tray part storage controller 119 that performs these controls is provided at a lower portion of the pallet conveying part 45.

Fig. 10 is a plan view showing the layout of the tray member storing device 29 and the tray member supplying device 23. The pallet storing section 43 and the pallet transporting section 45 are arranged along the path 15 (see fig. 1). That is, the tray member storing device 29 is disposed such that its long edge follows the path 15. Further, the pallet conveying section 45 of the pallet component storing device 29 is connected to the component mounting device 13 via the pallet component feeding device 23 in the direction along the Y axis. As a result, the component mounting system 11 is disposed in an L-shaped space in a plan view, in which the pallet storing section 43 and the pallet transporting section 45 on the long sides are arranged in a direction along the X axis, and the pallet storing section 43 and the pallet transporting section 45 are connected to the pallet component feeding device 23 in a direction intersecting the X axis.

Thus, the component mounting system 11 according to the first embodiment includes: a component mounting device 13 that takes out the component 33 stored in the tray 31 by a component mounting portion (e.g., a mounting head 35) and mounts the component 33 on the substrate 17; a tray member supply device 23 that supplies the tray 31 to a position where the tray 31 can be taken out by a member mounting portion (for example, a mounting head 35); and a tray member storing unit 29 that supplements the tray 31 in the tray member supplying unit 23. The tray member storing device 29 includes: a pallet storing section 43 capable of storing a magazine 41 that allows insertion and removal of the pallet 39 of the pallet 31 on which the storage part 33 is placed along a first axis (for example, X axis) in the inner space of the cover 109; a component bank transfer section (e.g., pallet transfer section 45) that transfers the pallet 39 between the pallet storage section 43 and the component supply device (e.g., pallet component supply device 23); and a slide table device 123 including a slide table 127, the cartridge 41 being placed on the slide table 127, and the cartridge 41 being moved between the inside and the outside of the cover 109 along a second axis (for example, Y axis) intersecting the first axis in a plane along the horizontal plane, the slide table 127 being capable of protruding outward from the inside of the cover 109.

In the tray member storage device 29, the slide table device 123 may further include a forward and backward driving portion 129 that projects the slide table 127 to the outside of the cover 109.

Next, a configuration of a control system of the tray part storage 29 according to the first embodiment will be described.

Fig. 11 is a block diagram of the tray member storing device 29. The tray component storing device 29 includes a pallet conveying section 45, a slide table device 123, an operating section 121, a connector 117, and a tray component storing device controller 119. The power supply unit 155 outside the tray member storage 29 is connected to the connector 117 through a power supply cable 157. An external power supply 159 is connected to the power supply unit 155 through a power supply cable 157. The power supply unit 155 is also directly connected to the tray component storage controller 119 via a signal line 161.

The tray part storage controller 119 includes a pallet transfer controller 153, a slide table controller 163, and a storage unit 165.

When the pallet transfer controller 153 receives a request instruction of the component 33 from the component mounting device 13, the pallet transfer controller 153 refers to the component storing information stored in the storage unit 165, and sends an instruction to the pallet transfer section 45 to withdraw the pallet 39 holding the pallet 31 of the component 33 from the pallet storing section 43. The pallet transfer section 45 extracts the corresponding pallet 39 from the pallet storage section 43 based on an instruction from the pallet transfer controller 153, inserts the extracted pallet 39 into the magazine 41 of the replacement pallet storage section 51 in the pallet component supply device 23, and completes supply of the pallet 39 to the pallet component supply device 23. As a result of referencing the component storing information stored in the storage unit 165, when there is no requested component 33 or when the remaining amount is small (for example, when the remaining amount is smaller than a prescribed amount), the pallet transfer controller 153 displays an instruction of the requested component 33 from the pallet component storing device 29 on the operation section 121 and notifies that a component shortage occurs or is about to occur.

For example, when a withdrawal command is input from the operation section 121, the slide table controller 163 transmits a command to switch the port of the valve connected to the cylinder 131 (see fig. 18) to the withdrawal operation side to the slide table device 123. The slide table device 123 switches the valve based on a command from the slide table controller 163. By this switching, the drive shaft of the cylinder 131 (see fig. 18) advances, and the slide table 127 passes through the cartridge replacement window 111 and advances to the passage side. When a storage instruction is input from the operation section 121, the slide table controller 163 sends an instruction to switch the port of the valve connected to the cylinder 131 (see fig. 18) to the storage operation side to the slide table device 123. The slide table device 123 switches the valve based on a command from the slide table controller 163. By this switching, the drive shaft (see fig. 18) of the air cylinder 131 is retreated, and the slide table 127 is stored in the pallet storing section 43. The slide table controller 163 can advance and retract the slide table 127 by a forward and reverse command from the component mounting device 13 or a magazine transfer device (not shown).

The storage unit 165 is configured to use a data recording device such as a flash memory, a Hard Disk Drive (HDD), or a Solid State Drive (SSD), and store deposit information. The storage unit 165 stores the number of components 33 to be replenished to the component mounting device 13, a storage address (e.g., a combination of the numbers of the magazine 41, the pallet 39, and the tray 31, etc. on which the respective components 33 are placed), and component storing information indicating whether or not there is replenishment to the component mounting device 13.

Next, an example of a specific operation when conveying a pallet will be described.

Fig. 12 is a diagram showing an operation of the pallet conveying section 45 immediately before the pallet 39 is extracted from the pallet storing section 43. The pallet 39 is accommodated in the pallet storing section 43 such that the second engaging section 77 is provided on a surface facing the pallet conveying section 45. To supply the pallet 39 to the pallet member supply device 23, the drawing device 141 of the pallet conveying part 45 is moved in the up-down direction (direction along the Z axis), and the processor engaging lever 81 provided on the drawing device 141 is engaged with the second engaging part 77 provided on the desired pallet 39.

Fig. 13 is a diagram showing an operation of the pallet conveying section 45 after the pallet 39 is extracted from the pallet storing section 43. The drawing device 141 in which the processor engagement lever 81 is engaged with the second engagement portion 77 draws out the pallet 39 together with the processor engagement lever 81 in the X direction by driving a traction motor (not shown). Short side portions of both sides of the pallet 39 drawn out by the drawing device 141 are supported from below by a pair of pallet guides 151.

Fig. 14 is a diagram showing the operation of the tray conveying section 45, in which the drawing device 141 is rotated in the clockwise direction. Next, the drawing device 141 supporting the pallet 39 is rotated clockwise by 90 degrees by the driving of the processor motor 145. In the pallet 39 rotated 90 degrees clockwise, the first engaging portion 75 which is not engaged with the processor engaging lever 81 is provided on one side of the replacement pallet storing portion 51. The drawing device 141 is provided such that the processor engagement lever 81 engaged with the second engagement portion 77 is located on the passage side in the direction along the Y axis.

Fig. 15 is a diagram showing an operation of the pallet conveying section 45 that inserts the pallet 39 into the pallet component feeding device 23. The drawing device 141 moves the processor engaging lever 81 in the Y direction. When the processor engaging lever 81 moves in the Y direction, the pallet 39 is inserted into the replacement pallet storage section 51 in the pallet part supply device 23 while sliding on the pallet guide 151. At this time, when the pallet 39 is inserted at different heights, the elevation base 137 is elevated and lowered to a desired height by the pallet processor elevation 135. The drawing device 141, which inserts the pallet 39 into the pallet part feeding device 23, is moved upward or downward by the driving of the pallet processor lifting part 135 to release the engagement with the second engagement part 77, and then is retracted in a direction away from the pallet part feeding device 23. The pallet conveying part 45 returns the processor engaging lever 81 to the retracted position and completes the supply of the pallet 39 to the pallet part supply device 23.

In the tray member supply device 23, in order to collect the empty pallet 39 that consumes the member 33 in the pallet storage section 43, the empty pallet 39 is moved to the pallet storage section 43 by the reverse operation procedure described above.

Next, the slide table device 123 will be further described.

Fig. 16 is a plan view of the slide table device 123 in which the slide table 127 is stored. The tray member storage unit 29 includes a pallet storage unit 43 and a slide table unit 123. The pallet storing section 43 is capable of storing a magazine 41, which allows insertion and removal of the pallet 39 of the pallet 31 on which the components 33 are stored, along a first axis (for example, X axis), in the inner space of the cover 109. The slide table device 123 includes a slide table 127. The slide table 127 is used to mount the cartridge 41 and move the cartridge 41 between the inside and the outside of the cover 109 along a second axis (e.g., Y-axis) intersecting the first axis in a plane along the horizontal plane. That is, the slide table 127 may protrude outward from the inside of the cover 109.

The slide table device 123 includes a slide rail 167 that supports the slide table 127 and extends and retracts along a second axis (e.g., the Y-axis). The slide table 127 moves between the outside and the inside of the cover 109 with the extension and retraction of the slide rail 167. The slide rail 167 includes a fixed rail 169 (see fig. 18), a connection rail 171 (see fig. 18), and a movable rail 173 (see fig. 18).

Among the slide rails 167, a fixing rail 169 is fixed to the fixing frame 125 of the pallet storing section 43 by an L-shaped metal fitting 175. The connection rail 171 is connected in parallel with the fixed rail 169 and is slidable in the extending direction of the fixed rail 169. About half of the entire length of the connection rail 171 may advance from the fixed rail 169 in the Y direction. The connection rail 171, about half of which has advanced from the fixed rail 169, is restricted from further advancement by a stopper mechanism (not shown). The movable rail 173 is connected in parallel with the connection rail 171 and is slidable in the extending direction of the connection rail 171. About half of the entire length of the movable rail 173 may advance in the Y direction from the connection rail 171. About half of the movable rail 173, which has advanced from the connection rail 171, is restricted from further advancement by a stopper mechanism (not shown).

Therefore, in the sliding rail 167, when the movable rail 173 advances, about half of the entire length of the movable rail 173 is supported by the connection rail 171, and about half of the entire length of the connection rail 171 advances from the fixed rail 169 and the movable rail 173. Thus, the movable rail 173 can be withdrawn from the fixed rail 169 for substantially its entire length (see fig. 18). Thus, the slide rail 167 may have substantially the same withdrawal length as the storage space.

The slide table device 123 may comprise a single slide rail 167 or a plurality of slide rails 167. In the first embodiment, the slide table device 123 includes two slide rails 167 extending along a second axis (e.g., Y axis) and arranged in parallel at intervals in a direction along a first axis (e.g., X axis). The two parallel sliding rails 167 face each other, while the corresponding movable rail 173 is located on the inside. Inside the movable rail 173, slide bases 177 each having an L-shaped cross section (see fig. 17) are fixed in the longitudinal direction of the movable rail 173. A pair of slide bases 177 parallel to each other are connected to each other by a plurality of connection plates 179. The slide base 177 and the link plate 179 constitute the slide block 127. The slide table 127 has a size to accommodate at least one magazine 41.

Fig. 17 is a perspective view of the slide table 127. The slide base 177 is provided with a first adjusting portion that adjusts the position of the cartridge 41 relative to the slide table 127 in the first axis (e.g., X-axis) direction, and a second adjusting portion that adjusts the position of the cartridge 41 relative to the slide table 127 in the second axis (e.g., Y-axis) direction. Each slide base 177 has an L-shaped cross section with the horizontal member on the inside and the rising member upstanding on the outside.

The first adjusting portion serves as an X-alignment guide 181. A pair of X alignment guides 181 are spaced apart in the extending direction of each slide base 177, and a total of four X alignment guides 181 are fixed. The X alignment guide 181 is an upstanding plate perpendicular to the side plate 83 (see fig. 6) of the magazine 41, and a pair of X alignment guides 181 provided at positions facing each other on the two slide bases 177 include inclined surfaces 183 that are separated from each other toward the upper side. That is, when seen from a direction along the Y-axis, the pair of X alignment guides 181 expands upward and is inclined in a Y-shape (see fig. 19). The X alignment roller 93 (see fig. 6) provided on the side plate 83 of the cartridge 41 is guided while sliding on the inclined surface 183 so that the X alignment roller 93 fits between the pair of X alignment guides 181.

The second adjustment part is a Y alignment guide 187 (see fig. 25). A pair of Y alignment guides 187 are spaced apart in the extending direction of each slide base 177, and a total of four Y alignment guides 187 are fixed inside the four X alignment guides 181. The Y alignment guide 187 is an upstanding plate perpendicular to the side plate 83 of the magazine 41, and each of a pair of Y alignment guides 187 provided at positions facing each other on the two slide bases 177 is formed in a trapezoidal shape formed by chamfering one corner of a square on the X alignment guide 181 side. That is, when viewed from a direction along the X axis, the pair of Y alignment guides 187 expands downward and is inclined in an a shape (see fig. 25). Outside both of the pair of Y alignment guides 187, the cartridge 41 is positioned relative to the slide table 127 by guiding the Y alignment roller 99 provided on the lower surface of the bottom plate 87 of the cartridge 41 by the inclined surface 185.

Fig. 18 is a plan view of the slide table device 123 that advances the slide table 127. The tray member storage device 29 may be provided with a forward and backward driving portion 129 in the slide table device 123. The advance and retreat driving portion 129 allows the slide table 127 to advance and retreat automatically between the outside and the inside space of the cover 109.

In the first embodiment, the advance and retreat driving portion 129 is provided between two slide rails 167 (see fig. 18).

The advance and retreat driving portion 129 includes a first rack 189, a second rack 191, a pinion 193, and an advance and retreat driving source.

The first rack 189 is fixed inside the cover 109 in a state where its longitudinal direction is parallel to the second axis (e.g., Y axis). More specifically, the first rack 189 is fixed to the mount 125. The second rack 191 is mounted on the slide table 127 and is disposed parallel to the first rack 189 in such a manner as to face the first rack 189. The pinion 193 is engaged with the first rack 189 and the second rack 191. The advance and retreat driving source moves the pinion 193 along a second axis (for example, Y axis).

In the first embodiment, the advance and retreat driving source is, for example, an air cylinder 131 that advances and retreats the advance and retreat driving shaft from the air cylinder. A valve or the like for supplying operation air is connected to the cylinder 131. By switching the plurality of ports of the valve, the advancing and retreating drive shaft of the cylinder 131 can be driven in the direction for advancing or retreating.

A slider 195 is fixed to the front end of the advance and retreat driving shaft of the cylinder 131. The slider 195 is guided by a slide rail 197 fixed to the mount 125 in a direction along the Y axis and moves linearly. The pinion 193 is rotatably supported by a slider 195 with a direction along the Z axis as a rotation center.

Fig. 19 is a front view of the slide table device 123 seen from the passage side. The slide table device 123 is disposed such that a pair of parallel slide rails 167 extending in the direction along the Y axis are fixed to the mount 125 when viewed from the direction along the Y axis. The slide base 177 is fixed inside (i.e., on the movable rail side) each of the pair of slide rails 167. The pair of slide bases 177 constitute a slide table 127 fixed by a connection plate 179. The cylinder 131 as a driving source of advance and retreat is accommodated in a space surrounded by a pair of slide bases 177 and a connection plate 179, and is fixed to the mount 125. Further, the pinion 193 advanced and retracted by the advance and retreat driving shaft of the cylinder 131 is engaged with the first rack 189 fixed to the fixing frame 125 and the second rack 191 fixed to the slide base 177 in a state sandwiched therebetween.

Fig. 20 is a conceptual diagram of an advancing and retreating mechanism using the cylinder 131 as an advancing and retreating driving source. The advance and retreat driving portion 129 moves along a second axis (Y axis) while rotatably supporting the pinion 193 on the slider 195. When the slide base 177 is accommodated in the cover 109, the pinion 193 is located on the rear side (the side opposite to the advancing side of the slide table) of the first rack 189 and is engaged with the first rack 189. At this time, the front end side in the advancing direction of the second rack 191 fixed to the slide base 177 is engaged with the pinion 193.

In the slide table device 123, when the cylinder 131 is driven and the pinion gear 193 moves a in the advancing direction while meshing with the first rack 189, the second rack 191 meshing with the pinion gear 193 is extracted by a movement amount (a+a=2a) twice the movement amount of the pinion gear 193 in the advancing direction.

Fig. 21 is a conceptual diagram of an advancing and retreating mechanism using a motor as an advancing and retreating driving source. The forward and backward driving unit 129 has a structure using a forward and backward driving motor 199 as a forward and backward driving source. In this case, the fixing frame 125 rotatably supports a pair of sprockets 201 spaced apart along the X-axis, and the rotation center of each sprocket is along the Y-axis. An endless chain 203 is wound around the pair of sprockets 201. The chain 203 rotatably supports a pinion 193 that meshes with both the first rack 189 and the second rack 191. When one sprocket 201 is driven by the advance and retreat driving motor 199, the pinion 193 moves with the movement of the chain 203. Therefore, as in the case of the movement performed by the cylinder 131, the pinion 193 can be moved in the direction along the X-axis in a state of being meshed with the two racks. According to the advance and retreat driving portion 129 in which the advance and retreat driving motor 199 is used as the advance and retreat driving source, the slide table 127 can advance and retreat without using a pneumatic device.

Fig. 22 is a conceptual diagram showing a variable stroke structure of the advancing and retreating mechanism. Further, the advance and retreat driving portion 129 may coaxially fix the large diameter pinion 205 and the small diameter pinion 207. In this case, for example, the small diameter pinion 207 (outer circumferential length a) is meshed with the first rack 189, and the second rack 191 is meshed with the large diameter pinion 205 (outer circumferential length 2A) coaxially fixed thereto. According to the advance and retreat driving portion 129, when the moving distance of the small diameter pinion gear 207 is a, the extraction distance of the second rack 191 is a+2a=3a. In this way, the advance and retreat driving portion 129 can freely set the enlargement ratio of the stroke by combining a plurality of pinion gears 193 having different diameters (outer peripheral lengths). Therefore, the advance and retreat driving portion 129 can realize a highly versatile advance and retreat mechanism suitable for the slide table device 123 having different extraction lengths.

Next, the positioning operation of the slide table device 123 will be described.

Fig. 23 is a perspective view of the magazine 41 positioned and placed on the slide table 127. By placing the cartridge 41 on the slide table 127, each of the X-axis direction, the Y-axis direction, and the Z-axis direction is positioned.

Fig. 24 is a diagram showing a positioning operation mainly performed by the X alignment guide 181 in the slide table 127. In the slide table device 123, the magazine 41 is moved downward in the direction along the Z axis, so that the slide table device 123 is placed on the slide table 127. The placement operation may be performed manually (i.e., by a worker) or may be performed automatically. When the magazine 41 descends in a direction approaching the slide table 127, the X alignment roller 93 of the magazine 41 comes into contact with the first regulating portion (for example, the X alignment guide 181). When the X-alignment roller 93 is guided by the X-alignment guide 181, the position of the magazine 41 in the first axis direction (for example, the X-axis direction) is positioned relative to the slide table 127.

Fig. 25 is a diagram showing a positioning operation mainly performed by the Y alignment guide 187 in the slide table 127. In the cartridge 41, the Y alignment roller 99 is in contact with the second regulating portion (e.g., the Y alignment guide 187) at substantially the same time as the contact between the X alignment guide 181 and the X alignment roller 93. When the Y-alignment roller 99 is guided by the inclined surface 185 of the Y-alignment guide 187, the position of the cartridge 41 in the second axial direction (e.g., Y-axis direction) is positioned relative to the slide table 127.

When the magazine 41 is moved to and placed in the final lowered position, the lower surface of the bottom plate 87 is in contact with the Y-alignment guide 187. The lower surface of the bottom plate 87 is in contact with four Y-alignment guides 187, so that the position of the magazine 41 in the Z-axis is positioned relative to the slide table 127. Thus, the cartridge 41 is positioned in the X, Y and Z directions with respect to the slide table 127 while the placement of the cartridge 41 on the slide table 127 is completed.

Next, the operation of the tray member storing device 29 according to the first embodiment will be described.

The component storing device (for example, the tray component storing device 29) includes: a magazine 41 that allows insertion and removal of a component storage 69 (e.g., a pallet 39 on which the tray 31 is placed) of the storage components 33 along a first axis (e.g., an X-axis); a storage (e.g., pallet storage 43) that allows for feeding and retrieving the magazine 41 along a second axis (e.g., Y-axis) intersecting the first axis in a plane along the horizontal plane; and a component bank transfer portion (e.g., pallet transfer portion 45) that transfers the component bank 69 (e.g., pallet 39) from the magazine 41 stored in the magazine along the first axis. The holder includes a housing (e.g., a lid 109) that forms an interior space capable of storing the cartridge 41. The housing has an opening (e.g., cartridge replacement window 111) through which the cartridge 41 can be fed into and removed from along the second axis.

In the tray member storage device 29 according to the first embodiment, the tray 31 of the storage member 33 is placed on the pallet 39. The pallet 39 can be fed in and out along the first axis and stored in the magazine 41. In the magazine 41, a plurality of pallets 39 are stored in a plurality of levels in the up-down direction. The magazine 41 is capable of simultaneously transporting a plurality of stored pallets 39. The plurality of cartridges 41 are stored in a storage (e.g., pallet storage 43). In the pallet storing section 43, a plurality of cartridges 41 are stored in a plurality of levels in the up-down direction. The pallet transfer part 45 is integrally connected to the pallet storing part 43 along the first axis. The pallet conveying section 45 conveys the pallets 39 one by one while feeding the pallets 39 into the cartridges 41 stored in the pallet storage section 43 and taking out the pallets 39 from the cartridges 41 stored in the pallet storage section 43 along the first axis.

In the tray member storage device 29, the pallet storage section 43 and the pallet transport section 45 are integrally connected. The pallet storing section 43 and the pallet transporting section 45 constitute the pallet component storing device 29. At least the pallet storage 43 requires installation space for one pallet. In addition, at least an installation space for one pallet is also required in the pallet conveying part 45. Therefore, the pallet component storage 29 formed by the pallet storing part 43 and the pallet transporting part 45 has a rectangular shape that requires installation space for at least two pallets in plan view.

In the tray member storing device 29, a pallet storing section 43 and a pallet conveying section 45 are arranged along the path 15. That is, the tray member storing device 29 is disposed such that the long side of the rectangular shape is along the passage 15 in a plan view.

In the tray member storage 29, an opening (e.g., a cartridge replacement window 111) is provided in a housing (e.g., a cover 109) of the pallet storage 43. The pallet storing section 43 allows the feeding and the taking out of the cartridge 41 along the second axis (Y axis) via the cartridge replacement window 111. The second axis is along the direction of intersection of the passageway 15 with the first axis. That is, as described above, in the tray member storing device 29 in which the long edge is provided along the path 15, in the pallet storing section 43 and the pallet conveying section 45 arranged along the path 15, the magazine replacing window 111 is directed to the side surface of the pallet storing section 43 facing the path 15, and the magazine 41 can be sent into and taken out from the pallet storing section 43 from the path 15 in the direction (front-rear direction) along the second axis (Y axis).

The tray member storing device 29 enables exchange of the cartridges 41 from the passage side in the direction along the Y axis, thereby facilitating exchange work of the cartridges 41 with a wide space on the passage. Access to truck mounted feeders (splice operations, feeder replacement or truck replacement) is unobstructed. Further, when the cartridges are automatically exchanged by the transfer robot, it is not necessary to access one side (left and right) of the tray member storing device 29.

The tray member storage device 29 includes a slide table device 123 that is provided in the inner space and on which the cartridge 41 is placed, and that moves the cartridge 41 along the second axis between the outside of the housing and the inner space through the opening.

In the tray member storage device 29, the pallet storage portion 43 includes a slide table device 123 in an inner space covered by the cover 109. The slide table device 123 is provided to correspond to the position of the cartridge replacement window 111. The slide table device 123 allows the cartridge 41 to be moved between the inner space of the cover 109 and the outside of the cover 109 by passing through the cartridge replacement window 111 along a second axis (Y axis).

In the pallet storing section 43, a plurality of cartridges 41 are stored in a plurality of levels in the up-down direction. The pallet 39 stored in each magazine 41 can be taken in and out by the pallet conveying section 45 in the direction along the X axis.

One of the plurality of cartridges 41 stored in a plurality of stages in the up-down direction is placed on the slide table device 123. The one cartridge 41 can be moved into and out of the lid 109 through the cartridge replacement window 111 by the slide table means 123. That is, the tray member storing device 29 allows replacement of only the one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a conveying section (i.e., exchanging section) that exchanges the cartridges 41 one by one between the outside and the inside space of the pallet storing section 43.

The pallet 39 on which the components 33 are stored in the pallet 31 is sequentially extracted from the magazine 41 placed on the slide table device 123 by the pallet conveying section 45. In the empty space of the magazine 41 from which the pallet 39 is extracted, the pallet conveying section 45 stores the pallet 39, and the empty pallet 31 on which the components 33 are consumed is placed on the pallet 39. That is, the cartridges 41, which are replenished with the components 33 placed on the slide table device 123, are sequentially replaced with empty pallets 39 by the pallet conveying section 45.

When all the stored pallets 39 are replaced with empty pallets 39, the cartridges 41 placed on the slide table device 123 are moved to the outside of the cover 109 (onto the way) by the slide table device 123. When the slide table device 123 is withdrawn, each cartridge 41 that moves on the path and in which the component is consumed is replaced manually or by a cartridge transfer device with a cartridge 41 that is replenished with the component 33 together with the cartridge 41.

In the tray member storing device 29, since the magazine 41 is further extracted onto the path from the magazine replacement window 111 provided on the path side of the pallet storing portion 43 by the slide table device 123, the magazine 41 having a weight of about 20kg, for example, can be easily replaced.

The slide table device 123 can be manually pulled out from the passage side. In this case, the slide table device 123 drawn out to the passage side serves as a rack, and a wide space on the passage serves as a work space, thereby facilitating manual replacement work.

In the tray member storage device 29, the slide table device 123 further includes a forward and backward driving portion 129 that projects the slide table 127 on which the magazine 41 is placed to the outside of the housing.

In the tray member storage device 29, the advance and retreat driving portion 129 is provided in the slide table device 123. When the forward/backward movement driving portion 129 is operated, the forward/backward movement driving portion 129 automatically advances/retreats the slide block 127 between the outside and the inside space of the cover 109 via the cartridge replacement window 111. Thus, the tray component storage 29 facilitates replacement automation of the cartridge 41 when the self-propelled cartridge transfer device is operated on the pathway at low equipment cost without the need for a large lifting device or the like.

The component mounting system 11 according to the first embodiment includes: a component mounting device 13 that takes out the component 33 stored in the component storage 69 (e.g., the tray 31) by a component mounting portion (e.g., the mounting head 35) and mounts the component 33 on the substrate 17; a component supply device (e.g., a tray component supply device 23) that supplies a component storage 69 (e.g., a tray 31) to a position where the component 33 can be taken out by a component mounting portion (e.g., a mounting head 35); and a component storing device (e.g., a tray component storing device 29) that supplements the component storage 69 (e.g., the tray 31) in the tray component supplying device 23. The tray member storing device 29 includes: a magazine 41 that allows insertion and removal of a component storage 69 (e.g., a pallet 39 on which the tray 31 is placed) of the storage component 33 along a first axis (e.g., an X-axis), a storage (e.g., a pallet storage 43) that allows feeding and discharging of the magazine 41 along a second axis (e.g., a Y-axis) intersecting the first axis in a plane along a horizontal plane, and a component storage transfer (e.g., a pallet transfer 45) that transfers the component storage (e.g., the pallet 39) from the magazine 41 stored in the storage along the first axis (e.g., the X-axis). The storage (e.g., pallet storage 43) includes a housing (e.g., cover 109) that forms an interior space in which the magazine 41 may be stored. The housing includes an opening (e.g., cartridge replacement window 111) through which the cartridge 41 can be introduced and removed along a second axis (e.g., Y-axis).

In the component mounting system 11 according to the first embodiment, the pallet conveying section 45 conveys the pallet 39 between the pallet storing section 43 and the component mounting device 13. The pallet 39 is supplied in the order of the pallet storing section 43, the pallet transporting section 45, and the component mounting device 13, and is recovered in the order of the component mounting device 13, the pallet transporting section 45, and the pallet storing section 43. That is, the pallet 39 is supplied from the pallet storing section 43 to the component mounting device 13 via the pallet transporting section 45, and after the components 33 are consumed and the pallet 39 becomes empty, the pallet 39 is recovered from the component mounting device 13 to the pallet storing section 43 via the pallet transporting section 45.

On the factory floor, the plurality of component mounting devices 13 are arranged side by side in the left-right direction (direction along the X axis), so that the linear mounting lines 27 are arranged. Further, on a factory site where the production yield is large, a plurality of mounting wires 27 may be disposed in parallel with each other with the passage 15 along the X-axis passing through the front and rear portions of the component mounting device 13 interposed therebetween. In this case, the mounting wires 27 and the vias 15 are arranged in a parallel and alternating manner.

Here, in the case where the pallet storing section 43 and the pallet transporting section 45 are connected in a straight line to the rear of the component mounting device 13 provided in the related art in a new manner, the pallet storing section 43 and the pallet transporting section 45 extend in a direction (direction along the Y axis) intersecting the extending direction (direction along the X axis) of the mounting line 27.

As described above, since the passage 15 is arranged before and after the mounting of the wires 27, the pallet storing section 43 and the pallet conveying section 45 extending from the rear of the component mounting device 13 protrude into the passage 15 to some extent. On the other hand, in the factory floor design at the time of new installation, if the installation space of the protruding portion is enlarged and provided in the component mounting device 13 in order to secure the passage width, the factory floor area increases and the area productivity decreases.

In the component mounting system 11, the pallet storing section 43 and the pallet transporting section 45 are integrally connected to form the pallet component storing device 29. The pallet storing part 43 requires a mounting space for at least one pallet, and the pallet transporting part 45 also requires a mounting space for at least one pallet. Therefore, the pallet component storage 29 formed by the pallet storing part 43 and the pallet transporting part 45 has a rectangular shape that requires installation space for at least two pallets in plan view.

Accordingly, in the tray member storing device 29, the pallet storing section 43 and the pallet conveying section 45 are arranged along the path 15. That is, the tray member storing device 29 is disposed such that its long edge follows the path 15. Further, the pallet conveying section 45 of the pallet component storing device 29 is connected to the component mounting device 13 via the pallet component feeding device 23 in the direction along the Y axis. As a result, the component mounting system 11 is disposed in an L-shaped space in plan view in which the pallet storing part 43 and the pallet transporting part 45 are arranged on the long side in the direction along the X axis, and the pallet storing part 43 and the pallet transporting part 45 are connected to the pallet component feeding device 23 on the component mounting device side in the direction intersecting the X axis. Therefore, in the component mounting system 11, the direction of feeding and taking out the pallet of the pallet component supply device 23 is the direction perpendicular to the passage 15, and the direction of feeding and taking out the pallet of the pallet storing section 43 is the direction parallel to the passage 15.

By arranging the storage positions in such an L shape, the component mounting system 11 can prevent jumping into the path 15 (in other words, can enlarge the path width) by bending and positioning the positions of the pallet storage portions 43 at right angles, as compared with the case where the pallet storage portions 43, the pallet conveying portions 45, and the pallet component feeding device 23 are arranged in series on a straight line intersecting the path 15 between the equipment lines.

As described above, in the component mounting system 11, the pallet 39 is conveyed while changing its direction to the direction along the X axis (left-right direction) of the pallet storing section 43 and the pallet conveying section 45 and the direction along the Y axis (front-rear direction) of the pallet storing section 43 and the pallet component feeding device 23. Thus, the via width and area productivity can be ensured.

The component storing device (for example, the tray component storing device 29) according to the first embodiment includes: a storage (e.g., a pallet storage 43) capable of storing a cartridge 41 in an inner space of a housing (e.g., a cover 109), the cartridge allowing a component storage body (e.g., a pallet 39 on which a tray 31 is placed) of the storage component 33 to be inserted and removed along a first axis (e.g., an X-axis); and a slide table device 123 including a slide table 127, the cartridge 41 being placed on the slide table 127, and the cartridge 41 being moved between the inside and the outside of the housing along a second axis (for example, Y axis) intersecting the first axis in a plane along the horizontal plane, the slide table 127 being capable of protruding outward from the inside of the housing.

In the tray member storage device 29 according to the first embodiment, the storage (for example, the pallet storage section 43) includes the slide table device 123 in the inner space covered by the housing (for example, the cover 109). The slide table device 123 is capable of moving the cartridge 41 along a second axis (e.g., Y-axis) between the interior space of the lid 109 and the exterior of the lid 109.

In the pallet storing section 43, a plurality of cartridges 41 are stored in a plurality of levels in the up-down direction. The pallet 39 stored in each magazine 41 can be fed in and taken out in the direction along the X-axis.

One of the plurality of cartridges 41 stored in a plurality of stages in the up-down direction is placed on the slide table device 123. A cartridge 41 can be moved into and out of the lid 109 by means of the slide table arrangement 123. That is, the tray member storing device 29 allows replacement of only the one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a conveying section (i.e., exchanging section) that exchanges the cartridges 41 one by one between the outside and the inside space of the pallet storing section 43.

In the inner space of the pallet storing section 43, the pallet 39 on which the components 33 are stored in the pallet 31 is sequentially extracted from the magazine 41 placed on the slide table 127. In the empty space of the magazine 41 from which the pallet 39 is extracted, the pallet 39 is stored, and the empty pallet 31 on which the components 33 are consumed is placed on the pallet 39. That is, in the internal space of the pallet storage section 43, the component replenishment cartridges 41 placed on the slide table 127 are sequentially replaced with the empty pallet 39.

When all the stored pallets 39 are replaced with empty pallets 39, the magazine 41 placed on the slide table 127 is moved to the outside of the cover 109 (onto the way) by the slide table device 123. When the slide table 127 is extracted, each cartridge 41 moved onto the path is replaced by a new component replenishment cartridge 41 filled with components 33, either manually or by a cartridge conveyor.

In the tray member storing device 29, since the magazine 41 is drawn onto the passage by the slide table device 123, the magazine 41 having a weight of, for example, about 20kg can be easily manually replaced.

In the tray component storage 29, the slide table device 123 includes a slide rail 167, and the slide rail 167 supports the slide table 127 and extends and retracts along a second axis (e.g., Y-axis). The slide table 127 moves between the outside and the inside of the housing as the slide rail 167 is extended and retracted.

In the tray member storage device 29, the slide table 127 is supported by the slide rail 167. The slide rail 167 is capable of moving the slide table 127 between the interior space of the cover 109 and the exterior of the cover 109. For example, a single slide rail 167 may support the slide table 127. That is, the slide table 127 can advance and retreat between the inside and outside of the pallet storing section 43 by a retractable slide rail 167. When one slide rail 167 is used, the support structure of the slide table 127 is simplified.

In the tray member storage device 29, the slide table device 123 includes two slide rails 167 extending along a second axis (e.g., Y axis) and arranged in parallel at intervals in a direction along a first axis (e.g., X axis).

The tray member storage 29 is formed of two slide rails 167 that are parallel to each other and spaced apart in the direction along the X-axis. In the tray member storage device 29, the slide table 127 is supported by two slide rails 167, thereby increasing the allowable loading weight of the slide table 127. Further, since the slide table 127 is supported by the two slide rails 167 spaced apart from each other in the direction orthogonal to the advancing and retreating direction, the cartridge 41 can be stably supported as compared with the support performed by one slide rail 167.

In the tray member storing device 29, the slide table 127 includes a first adjusting portion (for example, the X-alignment guide 181) that adjusts the position of the magazine 41 in the first axis direction (for example, the X-axis direction) with respect to the slide table 127, and a second adjusting portion (for example, the Y-alignment guide 187) that adjusts the position of the magazine 41 in the second axis direction with respect to the slide table 127.

In the tray member storage device 29, the first adjusting portion and the second adjusting portion are provided in the slide table 127. The first adjusting portion (for example, the X-axis alignment guide 181) adjusts the position of the magazine 41 with respect to the slide table 127 in the first axis (for example, the X-axis) direction. A second adjustment (e.g., Y-alignment guide 187) adjusts the position of the cartridge 41 relative to the slide table 127 in a second axis (e.g., Y-axis) direction. The Y-alignment guide 187 also serves as a cartridge receiver that receives the cartridge 41 placed above. The Y-alignment guide 187 also serves as a magazine receiver, thereby adjusting the position of the magazine 41 in the Z-axis direction relative to the slide table 127. Thus, the relative positions of the cartridge 41 with respect to the slide table 127 in the X, Y and Z directions are located.

The component storing device (for example, the tray component storing device 29) includes: a storage (e.g., a pallet storage 43) capable of storing a cartridge 41 in an inner space of the housing, the cartridge allowing insertion and removal of a component storage 69 (e.g., a pallet 39 on which the pallet 31 is placed) of the storage component 33 along a first axis (e.g., an X-axis); and a slide table device 123 including a slide table 127, the cartridge 41 being placed on the slide table 127 and the cartridge 41 being moved between the inside and the outside of the housing along a second axis (for example, Y axis) intersecting the first axis in a plane along the horizontal plane, the slide table 127 being capable of protruding outward from the inside of the housing, and including a forward and backward driving portion 129 allowing the slide table 127 to protrude to the outside of the housing.

In the tray member storage device 29, the slide table 127 is driven by the advance and retreat driving portion 129. When the advance/retreat driving portion 129 is operated, the advance/retreat driving portion 129 automatically advances/retreats the slide table 127 between the outside and the inner space of the cover 109. Thus, the tray component storage 29 facilitates replacement automation of the cartridge 41 when the self-propelled cartridge transfer device is operated on the pathway at low equipment cost without the need for a large lifting device or the like.

In the tray member storage device 29, the slide table device 123 includes a slide rail 167, and the slide rail 167 supports the slide table 127 and extends and retracts along the second axis. The slide table 127 moves between the outside of the housing (e.g., the cover 109) and the inside of the housing (e.g., the cover 109) according to the extension and retraction of the slide rail 167.

In the tray member storage device 29, the slide table 127 of the slide table device 123 provided with the advance and retreat driving portion 129 is supported by the slide rail 167. The slide rail 167 is capable of moving the slide table 127 between the interior space of the cover 109 and the exterior of the cover 109. For example, a single slide rail 167 may support the slide table 127. That is, the slide table 127 can advance and retreat between the inside and outside of the pallet storing section 43 by a retractable slide rail 167. When one slide rail 167 is used, the support structure of the slide table 127 is simplified.

In the tray member storage 29, the slide table 127 includes two slide rails 167 that extend along the second axis and are arranged in parallel at intervals in a direction along the first axis.

In the tray member storage device 29, the slide table device 123 provided with the advance and retreat driving portion 129 includes two slide rails 167 that are parallel to each other and spaced apart in the direction along the X axis. In the tray member storage device 29, the slide table 127 is supported by two slide rails 167, thereby increasing the allowable loading weight of the slide table 127. Further, since the slide table 127 is supported by the two slide rails 167 spaced apart from each other in the direction orthogonal to the advancing and retreating direction, the cartridge 41 can be stably supported as compared with the support performed by one slide rail 167.

In the tray member storage device 29, the advance and retreat driving portion 129 is provided between the two slide rails 167.

In the tray member storage device 29, the slide table device 123 includes two slide rails 167 that are parallel to each other and spaced apart in the direction along the X axis. In the slide table device 123, the advance and retreat driving portion 129 is provided by an empty space portion between the two slide tables 127. Accordingly, the slide table device 123 can compactly form the forward and backward driving mechanism including the forward and backward driving portion 129.

In the tray member storage device 29, the advance and retreat driving portion 129 includes: a first rack 189 fixed inside the housing in a state that a longitudinal direction thereof is parallel to the second axis; a second rack 191 mounted on the slide table 127 and arranged in parallel with the first rack 189 in such a manner as to face the first rack 189; a pinion gear 193, the pinion gear 193 being engaged with the first rack 189 and the second rack 191; and an advance and retreat driving source (for example, an air cylinder 131) that moves the pinion 193 along the second axis.

In the tray member storage device 29, the slide table 127 is driven to advance and retreat by the advance and retreat driving portion 129. The advance and retreat driving portion 129 rotatably supports the pinion 193 and moves the pinion 193 along the second axis. Pinion 193 is engaged with first rack 189 fixed inside cover 109. On the other hand, the pinion 193 can advance and retreat relative to the cover 109 by the slide rail 167, and also meshes with a second rack 191 arranged parallel to the first rack 189 in a manner facing the first rack 189. That is, the pinion 193 is interposed between the first rack 189 fixed to the cover and the second rack 191 attached to the slide table 127 capable of freely advancing and retreating, and is engaged with both the first rack 189 and the second rack 191.

By the advance and retreat driving source (for example, the cylinder 131), the pinion 193 moves along the Y axis while being sandwiched by the two racks. When the slide table 127 retreats to the inside of the cover 109, the pinion 193 is located on the rear side of the first rack 189 (the side opposite to the advancing side of the slide table) and is engaged with the first rack 189. At this time, the front end side in the advancing direction of the second rack 191 mounted on the slide table 127 is engaged with the pinion 193.

When the advance and retreat driving source (for example, the cylinder 131) is driven and the pinion gear 193 rolls in the advancing direction while being engaged with the first rack 189, the second rack 191 engaged with the pinion gear 193 is drawn out in the advancing direction by a movement amount twice the movement amount of the pinion gear 193.

Therefore, in the tray member supply device 23, a necessary movement stroke of the slide table 127 can be ensured while accommodating the slide table device 123 in a compact size. In the advance and retreat driving portion 129, by changing the gear ratio between the pinion 193 and the rack, the movement stroke of the slide table 127 with respect to the movement stroke of the pinion 193 can be changed by the advance and retreat driving source.

In the tray member storing device 29, the slide table 127 is provided with a first adjusting portion (for example, an X-alignment guide 181) that adjusts the position of the cartridge 41 in the first axis direction and a second adjusting portion (for example, a Y-alignment guide 187) that adjusts the position of the cartridge 41 in the second axis direction.

In the tray member storing device 29, when the magazine 41 moves downward in the direction along the Z-axis, the X-alignment roller 93 of the magazine 41 comes into contact with the first regulating portion (for example, the X-alignment guide 181). When the X-alignment roller 93 is guided by the X-alignment guide 181, the position of the magazine 41 in the first axis direction (for example, the X-axis direction) is positioned relative to the slide table 127.

In the cartridge 41, the Y alignment roller 99 is in contact with a second regulating portion (for example, the Y alignment guide 187) simultaneously with the contact between the X alignment guide 181 and the X alignment roller 93. When the Y-alignment roller 99 is guided by the inclined surface 185 of the Y-alignment guide 187, the position of the cartridge 41 in the second axial direction (e.g., Y-axis direction) is positioned relative to the slide table 127.

When the magazine 41 is moved to and placed on the final lowered position, the lower surface of the bottom plate 87 is in contact with the four Y-alignment guides 187. Thus, the position of the magazine 41 in the Z axis is positioned with respect to the slide table 127. As a result, the cartridge 41 is positioned in the X, Y and Z directions with respect to the slide table 127 while the placement of the cartridge 41 on the slide table 127 is completed.

The component mounting system 11 according to the first embodiment includes: a component mounting device 13 that takes out the component 33 stored in the component storage 69 (e.g., the tray 31) by a component mounting portion (e.g., the mounting head 35), and mounts the component 33 on the substrate 17; a component supply device (e.g., a tray component supply device 23) that supplies a component storage 69 (e.g., a tray 31) to a position where the component 33 can be taken out by a component mounting portion (e.g., a mounting head 35); and a component storing device (e.g., a tray component storing device 29) that supplements the component storage 69 (e.g., the tray 31) in the tray component supplying device 23. The tray member storing device 29 includes: a storage (e.g., a pallet storage 43) capable of storing a magazine 41 in an inner space of the housing, the magazine allowing insertion and removal of a component storage 69 (e.g., a pallet 39 on which the pallet 31 is placed) of the storage component 33 along a first axis (e.g., an X-axis); a component bank transfer section (e.g., pallet transfer section 45) that transfers a component bank 69 (e.g., pallet 39) between the stocker and the pallet component feeding device 23; and a slide table device 123 including a slide table 127, the cartridge 41 being placed on the slide table 127, and the cartridge 41 being moved between the inside and the outside of the housing along a second axis (for example, Y axis) intersecting the first axis in a plane along the horizontal plane, the slide table 127 being capable of protruding outward from the inside of the housing.

In the component mounting system 11 according to the first embodiment, the pallet storing section 43 includes the slide table device 123 located in the inner space covered by the cover 109. The slide table device 123 can move the magazine 41 along the second axis (Y axis) between the inner space of the cover 109 and the outside of the cover 109.

In the pallet storing section 43, a plurality of cartridges 41 are stored in a plurality of levels in the up-down direction. The pallet 39 stored in each magazine 41 can be inserted and removed in the direction along the X-axis.

The pallet 39 having the components 33 stored therein in the pallet 31 thereon is sequentially moved from the magazine 41 placed on the slide table device 123 to the pallet component feeding device 23. In the empty space of the magazine 41 from which the pallet 39 is drawn, the pallet 39 is returned from the pallet component feeding device 23 and stored, and the empty pallet 31 on which the components 33 are consumed is placed on the pallet 39. That is, the cartridges 41 replenished by the members 33 placed on the slide table device 123 are sequentially replaced with empty pallets 39.

In the component mounting system 11, since the magazine 41 is further pulled onto the path from the path side of the pallet storing section 43 by the slide table device 123, the magazine 41 having a weight of, for example, about 20kg can be easily replaced.

The component mounting system 11 includes: a component mounting device 13 that takes out the component 33 stored in the component storage 69 (e.g., the tray 31) by a component mounting portion (e.g., the mounting head 35), and mounts the component 33 on the substrate 17; a component supply device (e.g., a tray component supply device 23) that supplies a component storage 69 (e.g., a tray 31) to a position where the component 33 can be taken out by a component mounting portion (e.g., a mounting head 35); and a component storing device (e.g., a tray component storing device 29) that supplements the component storage 69 (e.g., the tray 31) in the tray component supplying device 23. The tray member storing device 29 includes: a storage (e.g., a pallet storage 43) capable of storing a cartridge 41 in an inner space of a housing (e.g., a cover 109) that allows a component storage 69 (e.g., a pallet 39 on which a tray 31 is placed) of the storage component 33 to be inserted and removed along a first axis (e.g., an X-axis); a component bank transfer section (e.g., pallet transfer section 45) that transfers a component bank 69 (e.g., pallet 39) between the stocker and the pallet component feeding device 23; and a slide table device 123 including a slide table 127, the cartridge 41 being placed on the slide table 127, and the cartridge 41 being movable between an inside of the housing (e.g., the lid 109) and an outside of the housing (e.g., the lid 109) along a second axis (e.g., Y axis) intersecting the first axis in a plane along the horizontal plane, the slide table 127 being capable of protruding from the inside of the housing (e.g., the lid 109) to the outside of the housing (e.g., the lid 109). The slide table device 123 includes a forward and backward drive portion 129 that projects the slide table 127 to the outside of the housing.

In the component mounting system 11, the pallet storage section 43 includes a slide table device 123 located in the internal space covered by the cover 109. The slide table device 123 can move the magazine 41 along the second axis (Y axis) between the inner space of the cover 109 and the outside of the cover 109.

One of the plurality of cartridges 41 stored in a plurality of stages in the up-down direction is placed on the slide table device 123. The one cartridge 41 can be moved in and out of the lid 109 by means of the slide table means 123. That is, the tray member storing device 29 allows replacement of only the one magazine 41 placed on the slide table device 123. The slide table device 123 serves as a conveying section (i.e., exchanging section) that exchanges the cartridges 41 one by one between the outside and the inside space of the pallet storing section 43.

The pallet 39 having the components 33 stored therein in the pallet 31 thereon is sequentially moved from the magazine 41 placed on the slide table device 123 to the pallet component feeding device 23. In the empty space of the magazine 41 from which the pallet 39 is drawn, the pallet 39 is returned from the pallet component feeding device 23 and stored, with the empty pallet 31 on which the components 33 are placed on the pallet 39 being consumed. That is, the cartridges 41 replenished by the members 33 placed on the slide table device 123 are sequentially replaced with empty pallets 39.

When all the stored pallets 39 are replaced with empty pallets 39, the cartridges 41 placed on the slide table device 123 are moved to the outside of the cover 109 (onto the way) by the slide table device 23. When the slide table device 123 is withdrawn, each cartridge 41 that moves on the path and in which the components are consumed is replaced manually or by a cartridge conveyor with a cartridge 41 that is replenished with components 33 together with the cartridge 41.

In the component mounting system 11, since the magazine 41 is further drawn out onto the path from the path side of the pallet storing section 43 by the slide table device 123, the magazine 41 having a weight of, for example, about 20kg can be easily replaced.

In the component mounting system 11, the slide table 127 is driven by the advance and retreat driving portion 129. When the advance/retreat driving portion 129 is operated, the advance/retreat driving portion 129 automatically advances/retreats the slide table 127 between the outside and the inner space of the cover 109. Thus, the component mounting system 11 facilitates automation of replacement of the cartridge 41 when the self-propelled cartridge transfer device is operated on the pathway at low equipment cost that does not require a large lifting device or the like.
