[0009] (Embodiment 1) First, a first embodiment of the present invention will be described. Fig. 1 shows a component mounting device 1 to which the present invention is applied. In Fig. 1, the component mounting device 1 is a device that mounts components BH on a board KB, and includes a transport conveyor 12, a plurality of part feeders 13, a mounting head 14, and a head moving mechanism 15 on a base 11.

[0010] 1, the transport conveyor 12 extends in one direction in a horizontal plane on the base 11, transports the board KB in the horizontal direction, and positions the board KB at a predetermined work position. Hereinafter, the transport direction of the board KB by the transport conveyor 12 is referred to as the X direction. Also, the direction that intersects (is perpendicular to) the X direction in the horizontal plane is referred to as the Y direction, and the up-down direction is referred to as the Z direction.

[0011] 1, multiple part feeders 13 are arranged side by side in the X direction at the Y-direction end of base 11. Each of the multiple part feeders 13 functions as a component supply device, and each part feeder 13 supplies components BH to component supply ports 13K located near board KB positioned at the work position.

[0012] 1, the mounting head 14 is equipped with multiple nozzles 14a extending downward. The mounting head 14 can generate a vacuum suction force in each nozzle 14a. The mounting head 14 picks up the component BH supplied to the component supply port 13K by the part feeder 13 by sucking the component BH onto the nozzle 14a.

[0013] The head moving mechanism 15 is a mechanism for moving the mounting head 14 in a horizontal plane. The head moving mechanism 15 includes a Y beam 21, a connection portion 22, and an X beam 23, as shown in FIG.

[0014] 1, Y beam 21 extends in the Y direction above one side of base 11 in the X direction (here, to the right as seen from operator OP). Y beam 21 is fixed to base 11 at both front and rear ends, and is a fixed beam that does not move relative to base 11.

[0015] 1 and 2, connection part 22 is made of a block-shaped member as a whole, and is attached to the inner side of the left and right sides of Y beam 21 (the side facing the center of base 11). Two Y rails 21R extending in the Y direction are provided side by side in the vertical direction on the inner side of Y beam 21. Meanwhile, two connection part side engagement parts 22G are provided side by side in the vertical direction on the side of connection part 22 facing the inner side of Y beam 21. The two connection part side engagement parts 22G engage with the two Y rails 21R, allowing connection part 22 to slide freely along Y beam 21 (i.e., in the Y direction).

[0016] 2, Y-direction stator 31A, which is a stator of a linear motor, is provided between two Y rails 21R on the side of Y beam 21, and Y-direction mover 31B, which is a mover of the linear motor, is provided between two connection portion side engaging portions 22G of connection portion 22. Y-direction mover 31B is located close to Y-direction stator 31A.

[0017] The Y-direction stator 31A and the Y-direction mover 31B constitute a Y-direction linear motor 31 serving as a connection part moving mechanism that moves the connection part 22 along the Y-beam 21. For this reason, by controlling the supply of electricity to the Y-direction stator 31A, the Y-direction mover 31B can be moved in any direction (forward or backward) along the Y-direction stator 31A (i.e., the Y direction), and thus the connection part 22 (i.e., the X-beam 23) can be moved in the Y direction along the Y-beam 21.

[0018] Thus, in the first embodiment, Y-direction linear motor 31 functions as a connection part moving mechanism that moves connection part 22 in a direction along Y beam 21 (that is, in the Y direction).

[0019] 1, X beam 23 extends in the X direction above base 11, and one end is attached to connection part 22. In this way, X beam 23 is connected to Y beam 21 via connection part 22, and serves as a movable beam that is freely movable relative to Y beam 21 (i.e., relative to base 11).

[0020] 2, two X rails 23R extending in the X direction are provided side by side in the vertical direction on the front side of both sides in the front-rear direction (Y direction) of the X beam 23. Meanwhile, two head-side engagement parts 14G are provided side by side in the vertical direction on the surface (rear surface) of the mounting head 14 that faces the front surface of the X beam 23. The two head-side engagement parts 14G engage with the two X rails 23R, thereby allowing the mounting head 14 to slide freely in the direction along the X beam 23 (i.e., the X direction).

[0021] 2, an X-direction stator 32A, which is a stator of a linear motor, is provided between two X-rails 23R on the front side of the X-beam 23, and an X-direction mover 32B, which is a mover of the linear motor, is provided between two head-side engagement parts 14G of the mounting head 14. The X-direction mover 32B is located close to the X-direction stator 32A.

[0022] The X-direction stator 32A and the X-direction mover 32B constitute an X-direction linear motor 32 as a movement mechanism that moves the mounting head 14 along the X-beam 23. Therefore, by controlling the current supply to the X-direction stator 32A, the X-direction mover 32B can be moved in any direction (leftward or rightward) along the X-direction stator 32A (i.e., the X direction), and thus the mounting head 14 can be moved in the X direction along the X-beam 23.

[0023] 3 shows a control system controlled by a control device 40 provided in the component mounting device 1. The control device 40 operates the transport conveyor 12 to transport and position the board KB, and causes each of the multiple part feeders 13 to perform a component supply operation. The control device 40 also operates the Y-direction linear motor 31 and the X-direction linear motor 32 to move the mounting head 14 in a horizontal plane, and causes the mounting head 14 to suck and release the component BH through the nozzle 14a.

[0024] When the component mounting device 1 configured as described above performs a component mounting operation of mounting components BH on a board KB, first the transport conveyor 12 carries in the board KB sent from the upstream side of the component mounting device 1 and positions it at a prescribed work position (FIG. 1). Once the board KB is positioned at the work position, each part feeder 13 supplies the components BH, and the head moving mechanism 15 moves the mounting head 14 back and forth between the part feeders 13 and the board KB.

[0025] The mounting head 14 moves back and forth between the parts feeder 13 and the board KB, alternately picking up the components BH supplied by the parts feeder 13 and mounting the picked-up components BH onto the board KB. In this way, the components BH are mounted one after another onto the board KB. When all the components BH to be mounted on the board KB have been mounted on the board KB in this manner, the transport conveyor 12 carries the board KB out of the component mounting device 1, and the component mounting operation for one board KB is completed.

[0026] In component mounting device 1 configured as above, X beam 23 constituting head moving mechanism 15 has an upper surface member 41 constituting the upper surface, a front surface member 42 constituting the front surface, a rear surface member 43 constituting the rear surface, and a bottom surface member 44 constituting the bottom surface, and has a hollow structure inside, as shown in Figures 2 and 4. On the outer surface (front surface) of front surface member 42, the two X rails 23R and X-direction stator 32A mentioned above are provided extending in the X direction.

[0027] 1, 2 and 4, the base end side of X beam 23 is attached to connection portion 22. A tip plate 45 is attached to the end portion of X beam 23 on the tip side.

[0028] The rear member 43 of the X beam 23 (i.e., the member constituting the surface opposite to the surface on which the mounting head 14 is provided) is provided with two air inlets (a first air inlet 51 and a second air inlet 52) ​​that penetrate in the plate thickness direction (Y direction). The connection part 22 is provided with a connection part opening 53 that penetrates in the thickness direction (X direction). The connection part opening 53 faces at least a part of the Y-direction mover 31B provided in the connection part 22. Meanwhile, the tip plate 45 is provided with a tip part opening 54 that penetrates in the thickness direction (Y direction).

[0029] 4 and 5, the X beam 23 is provided with a first main guide member 61 and a first sub-guide member 62 that guide the air KK that has flowed in from the first air inlet 51 in the direction along the Y direction (specifically, the direction from the rear member 43 of the X beam 23 toward the front member 42) to travel along the X direction inside the X beam 23 and reach the Y-direction mover 31B. The X beam 23 is also provided with a second main guide member 63 and a second sub-guide member 64 that guide the air KK that has flowed in from the second air inlet 52 in the direction along the Y direction (similarly, the direction from the rear member 43 of the X beam 23 toward the front member 42) to travel along the X direction inside the X beam 23 and reach the tip plate 45.

[0030] The first main guide member 61 has an oblique surface (first oblique surface SM1) that is oblique to both the Y direction and the X direction. Therefore, the air KK that flows into the inside of the X beam 23 from the first air inlet 51 in the direction along the Y direction hits the first oblique surface SM1, changes direction, proceeds in the direction along the X direction, and is guided to the Y-direction mover 31B, which is the connection side element. The first main guide member 61 and the first sub-guide member 62 having such a first oblique surface SM1 constitute an air passage (first air passage KT1) that guides the air KK that flows into the inside of the X beam 23 from the first air inlet 51 to the base end side of the X beam 23 (FIGS. 4 and 5).

[0031] The air KK that flows into the inside of the X beam 23 from the first air inlet 51 and passes through the first air passage KT1 escapes to the outside of the connection part 22 through the connection part opening 53 provided in the connection part 22 (FIG. 5). In this way, the first air passage KT1 includes the first air inlet 51 provided on the side surface (specifically, the rear surface) of the X beam 23 to allow the air KK outside the X beam 23 to flow into the inside of the X beam 23, and the first air passage KT1 that guides the air KK that has flowed into the inside of the X beam 23 from the first air inlet 51 to the Y-direction mover 31B, which is the connection part side element, through the connection part opening 53 provided in the connection part 22. The air KK that has flowed into the inside of the X beam 23 from the first air inlet 51 in the direction along the Y direction is guided by an oblique surface (first oblique surface SM1) that constitutes a part of the first air passage KT1, and is guided in the X direction that intersects with the Y direction.

[0032] The second main guide member 63 also has an oblique surface (second oblique surface SM2) that is oblique to both the Y direction and the X direction, so that the air KK that flows into the inside of the X beam 23 from the second air inlet 52 in the direction along the Y direction hits the second oblique surface SM2, changes direction, proceeds in the direction along the X direction and is guided to the tip plate 45. The second main guide member 63 and the second sub-guide member 64 having such a second oblique surface SM2 form an air passage (second air passage KT2) that guides the air KK that flows into the inside of the X beam 23 from the second air inlet 52 to the tip side of the X beam 23 (FIGS. 4 and 5).

[0033] In the above-mentioned component mounting operation performed by the component mounting device 1, when the control device 40 operates the Y-direction linear motor 31 to move the X-beam 23 from the front side to the rear side in the Y direction, the X-beam 23 receives a relative wind from the rear to the front. As a result, air KK flows into the inside of the X-beam 23 from the first air inlet 51 and the second air inlet 52 provided in the rear member 43 (FIG. 5).

[0034] The air KK that flows into the inside of the X-beam 23 from the first air inlet 51 passes through the first air passage KT1 to the connection part opening 53 as described above, and escapes to the outside of the connection part 22 (i.e., the X-beam 23). At this time, the air KK that escapes to the outside of the connection part 22 from the connection part opening 53 absorbs heat generated in the connection part side element (Y-direction mover 31B) that constitutes part of the Y-direction linear motor 31, which is the connection part movement mechanism, and cools it.

[0035] Furthermore, the air KK that flows into the inside of the X beam 23 from the second air inlet 52 passes through the second air passage KT2 to reach the tip opening 54 as described above, and escapes to the outside of the X beam 23. The air KK that passes through the second air passage KT2 to escape from the tip opening 54 to the outside of the X beam 23, and the air KK that passes through the first air passage KT1 to escape from the connection opening 53 to the outside of the X beam 23 each remove heat generated in the X-direction stator 32A through the front member 42 of the X beam 23, so that the X-direction stator 32A is also cooled.

[0036] Thus, the component mounting device 1 in embodiment 1 includes a head moving mechanism 15 that moves the mounting head 14, a Y beam 21 as a first beam extending in the horizontal Y direction (first direction), an X beam 23 as a second beam that extends in the X direction (second direction) that intersects with the Y direction in the horizontal plane and has a connection part 22 located on the base end side that is slidably attached to the Y beam 21, and a Y-direction linear motor 31 as a connection part moving mechanism that moves the connection part 22 along the Y beam 21. The Y-direction mover 31B, which is a connection part side element that constitutes part of the connection part moving mechanism (Y-direction linear motor 31), is provided in the connection part 22, and the X-beam 23 is configured to include an air inlet (first air inlet 51) that allows external air KK to flow into the inside of the X-beam 23, and an air passage (first air passage KT1) that guides the air KK that has flowed into the inside of the X-beam 23 from this air inlet (first air inlet 51) through a connection part opening 53 provided in the connection part 22 to the Y-direction mover 31B, which is the connection part side element.

[0037] The air inlet (first air inlet 51) is provided on the side (rear) of the X beam 23, and the Y-direction linear motor 31, which is the connection part moving mechanism, moves the connection part 22 (i.e., the X beam 23) along the Y beam 21, so that the air KK received by the X beam 23 as a relative wind flows into the inside of the X beam 23 from the first air inlet 51. The air KK thus flowed into the inside of the X beam 23 is guided by the first air passage KT1 to the connection part side element (Y-direction mover 31B), so that the connection part side element is cooled, and the connection part 22 is unlikely to become hot even if the connection part moving mechanism (Y-direction linear motor 31) is frequently operated. Therefore, according to the component mounting device 1 in the first embodiment, it is possible to prevent the Y-direction mover 31B from becoming overheated, thereby preventing the operation of the head moving mechanism 15 from becoming unstable, and thus preventing a decrease in component mounting accuracy.

[0038] In the first embodiment, the air KK for cooling the connection part side element (Y-direction mover 31B) of the connection part moving mechanism (Y-direction linear motor 31) is introduced into the X-beam 23 by the movement of the X-beam 23, so no separate mechanism for cooling is required, and an inexpensive configuration can be achieved. In the first embodiment, the connection part side element is cooled when the X-beam 23 is moving, and is not cooled when the X-beam 23 is stopped. However, in the first place, the Y-direction linear motor 31 as the connection part moving mechanism is not operating when the X-beam 23 is stopped, and cooling of the Y-direction mover 31B, which is the connection part side element, is not necessarily required, so there is no particular inconvenience.

[0039] (Embodiment 2) Next, a description will be given of a second embodiment of the present invention. A component mounting device in the second embodiment is almost the same as the component mounting device 1 in the first embodiment described above, but the configuration of the X beam 23, which is the second beam, is different.

[0040] 6 and 7 show an X beam (referenced as "23A") in the second embodiment. The first difference between the X beam 23A in the second embodiment and the X beam 23 in the first embodiment is that the X beam 23A in the second embodiment does not have the air inlet (first air inlet 51 and second air inlet 52) ​​and guide members (first main guide member 61, first sub guide member 62, second main guide member 63 and second sub guide member 64) that the X beam 23 in the first embodiment has. Due to this difference, the X beam 23A in the second embodiment does not have two air passages, the first air passage KT1 and the second air passage KT2, that the X beam 23 in the first embodiment has, but has only one air passage (referred to as "straight air passage KT3") that extends linearly along the X direction inside the X beam 23. Note that the tip opening 54 that functions as an outlet for the air KK in the first embodiment functions as an air inlet that allows the air KK to flow into the straight air passage KT3 in the second embodiment.

[0041] The second difference between the X beam 23A in the second embodiment and the X beam 23 in the first embodiment is that an electric fan 70 serving as an air suction device, which the X beam 23 in the first embodiment did not have, is provided at the connection part 22. The electric fan 70 is disposed facing the Y-direction mover 31B, which is a connection part side element constituting a part of the connection part moving mechanism (Y-direction linear motor 31) (FIGS. 6 and 7). The operation of the electric fan 70, including its on / off operation, is controlled by the control device 40.

[0042] 6 and 7, while the electric fan 70 is operating, the air KK outside the X-beam 23 flows into the inside of the X-beam 23 through the tip opening 54 provided in the tip plate 45 (FIG. 7). The tip plate 45 is located opposite the connection part 22 where the electric fan 70 is provided in the X-direction, and the air KK flowing in from the tip opening 54 travels straight through the linear air passage KT3 extending along the X-direction to reach the connection part opening 53 of the X-beam 23, and escapes to the outside of the connection part 22 (i.e., the X-beam 23). At this time, as in the case of the first embodiment, the air KK escaping to the outside of the connection part 22 removes heat generated in the connection part side element (Y-direction mover 31B) constituting a part of the Y-direction linear motor 31 which is the connection part movement mechanism, so that the Y-direction mover 31B is cooled.

[0043] In this manner, the component mounting device in the second embodiment, like the component mounting device 1 in the first embodiment, includes a head moving mechanism 15 for moving the mounting head 14, a Y beam 21 extending in the horizontal Y direction, an X beam 23 extending in the X direction intersecting with the Y direction in the horizontal plane, and a connection part 22 located on the base end side slidably attached to the Y beam 21, and a Y-direction linear motor 31 as a connection part moving mechanism for moving the connection part 22 along the Y beam 21. The Y-direction mover 31B, which is a connection part side element constituting a part of the connection part moving mechanism, is provided in the connection part 22, and the X beam 23 is configured to include an air inlet (tip opening 54) for introducing the outside air KK into the inside of the X beam 23, and an air passage (straight air passage KT3) for guiding the air KK that has flowed into the inside of the X beam 23 from the air inlet (tip opening 54) to the Y-direction mover 31B, which is a connection part side element, through the connection part opening 53 provided in the connection part 22.

[0044] In the second embodiment, unlike the first embodiment, air KK is forcibly introduced into the X-beam 23 from the tip opening 54, which is an air inlet, by suctioning air with an electric fan 70, which is an air suction device provided inside the connection part 22. The air KK introduced into the X-beam 23 in this way is guided to the connection part side element (Y-direction mover 31B) by the linear air passage KT3, so that the connection part side element is cooled, and the connection part 22 is unlikely to become hot even if the connection part moving mechanism (Y-direction linear motor 31) is frequently operated. Therefore, according to the component mounting device 1 in the second embodiment, it is possible to prevent the Y-direction mover 31B from becoming overheated, thereby preventing the operation of the head moving mechanism 15 from becoming unstable, and thus preventing a decrease in component mounting accuracy. In embodiment 2, air KK can be taken in (flowed into) the inside of the X-beam 23 without moving the X-beam 23, so the connection side element (Y-direction mover 31B) of the connection moving mechanism (Y-direction linear motor 31) can be cooled even when the connection 22 (i.e., the X-beam 23) is not being moved.

[0045] The air passage inside the X beam 23 in the second embodiment is not limited to the linear air passage KT3 shown here, and may be an air passage bent inside the X beam 23 like the first air passage KT1 in the first embodiment. That is, like the first air passage KT1 in the first embodiment, the air KK may be introduced from an air inlet (first air inlet 51) provided on the side surface (rear surface) of the X beam 23, and the air KK (air KK sucked in by the electric fan 70) may be guided to the connection part 22 by an oblique surface (first oblique surface SM1).

[0046] In addition, in the second embodiment, the electric fan 70 sucks in the air KK outside the X beam 23 and takes it into the inside of the X beam 23, so the air inlet is not limited to the end (3 tip plate 45) or rear member 43 of the X beam 23, but may be provided in the top member 41 or bottom member 44 of the X beam 23, etc. Furthermore, the number of air inlets is not limited to one, but may be provided in multiple numbers.

[0047] As described above, in the component mounting device 1 in the first and second embodiments, the head moving mechanism 15 has a Y beam 21 extending in the horizontal Y direction, and an X beam 23 having a connection part 22 extending in the X direction intersecting the Y direction in the horizontal plane and located at the base end side, which is slidably attached to the Y beam 21, and a connection part side element (Y direction mover 31B) which constitutes part of the connection part moving mechanism (Y direction linear motor 31) which moves the connection part 22 along the Y beam 21 is provided on the connection part 22, and the X beam 23 is configured to have an air inlet which allows external air KK to flow into the inside of the X beam 23, and an air passage which guides the air KK which has flowed from this air inlet into the inside of the X beam 23 to the connection part side element through a connection part opening 53 provided in the connection part 22. Therefore, the connection part side elements can be cooled by air KK flowing into the inside of X-beam 23 from the air inlet, and even if the connection part moving mechanism is frequently operated, connection part 22 is unlikely to become hot, preventing the connection part side elements from becoming overheated and preventing the operation of head moving mechanism 15 from becoming unstable. Therefore, according to component mounting device 1 in embodiments 1 and 2, it is possible to prevent a situation in which the operation of head moving mechanism 15 becomes unstable due to overheating, resulting in a decrease in component mounting accuracy.

[0048] Although the first and second embodiments of the present invention have been described so far, the present invention is not limited to the above, and various modifications are possible. For example, in the above-mentioned embodiments, the connection part 22 is a separate member from the X-beam 23, but the connection part 22 may be a part of the base end side part of the X-beam 23. That is, the X-beam 23 may be configured to extend in a second direction (X direction) intersecting the first direction (Y direction) in the horizontal plane, and the connection part 22 located on the base end side may be slidably attached to the Y-beam 21.

[0049] In the second embodiment, the air suction device (electric fan 70) is provided in the connection portion 22, but it may be provided inside the X beam 23 (in the straight air passage KT3). In the second embodiment, the electric fan 70 is exemplified as the air suction device, but the air suction device need not necessarily be the electric fan 70 as long as it is a device that can draw in the air KK and cause air to flow from the air inlet into the second beam (X beam 23).

[0050] In addition, in embodiment 1, only one end of the X beam 23 was supported by the Y beam 21, and the other end of the X beam 23 simply functioned as an outlet for the air KK (the outlet for the air KK passing through the second air passage KT2). However, if two Y beams 21 are arranged in parallel on the base 11 and a connection portion 22 is provided on each end of the X beam 23 (the tip plate 45 is removed) and the two connection portions 22 are attached to the two Y beams 21, the cooling configuration for the connection portion side elements may be applied to both ends of the X beam 23.
