(See also FIGS. 3 (a) and 3 (b)). In the present embodiment, since a plurality of parts feeders 14 can be attached to the base 11 in parallel, a plurality of slits 51 are provided in the hem 41 correspondingly.

In FIGS. 6 (a) and 6 (b) and 7 (a) and 7 (b), the plurality of slits 51 provided in the hem 41 are provided in parallel with each other, and the distance KK (FIG. 9) thereof is set. The pitch corresponds to the parallel spacing of the parts feeders 14 in the feeder base 22 (pitch that is an integral multiple of the distance between adjacent slots). Each of the plurality of slits 51 opens toward the outside of the base 11, and a tapered portion 51P having a shape that expands toward the outside is provided at the outer end portion (the portion that opens toward the outside). (Fig. 9).

The limit of the movement area SH of the mounting head 16 is that in the rear area of the base 11, the nozzle 16N (nozzle 16N arranged in the frontmost position when the nozzles 16N are provided in a plurality of rows in the front-rear direction) is a part. It is a position positioned above the component supply port 14K of the feeder 14 (FIGS. 8A and 10A). On the other hand, in the front region of the base 11, the limit of the moving region SH of the mounting head 16 is the substrate. It is a position where the camera 17 is positioned above the component supply port 14K (FIGS. 8 (b) and 10 (b)).

As shown in FIG. 10B, when the substrate camera 17 located behind the nozzle 16N is located above the component supply port 14K, the nozzle 16N is outside (front side) of the base 11 with respect to the component supply port 14K. ) Will be located. That is, in the front region of the base 11, the limit of the movement region of the mounting head 16 is expanded to the outside as compared with the rear region (or the conventional configuration) of the base 11.

As shown in FIGS. 11 (a) and 11 (b) and FIGS. 12 (a) and 12 (b), the lower surface of the hem 41 is extremely close to the upper surface of the parts feeder 14, and the clearance CL in the vertical direction of both is very close. It is very small. This is because the vertical distance between the lower end of the nozzle 16N in the non-lowered state and the upper surface of the parts feeder 14 is originally set to an extremely small value.

In FIGS. 11 (a) and 11 (b) and FIGS. 12 (a) and 12 (b), each part feeder 14 projects upward from an intermediate portion in the attachment / detachment direction (Y-axis direction) with respect to the base 11. It has a portion 14T. The upward protrusion 14T includes, for example, an operation unit for operating a part of the mechanism of the parts feeder 14 in a state where the parts feeder 14 is attached to the base 11. As can be seen from FIGS. 11 (b) and 12 (b), the height of the upper end portion of the upward protruding portion 14T is higher than that of the lower surface of the hem portion 41 when the parts feeder 14 is attached to the base 11. Located in position. However, the height of the upper end of the upward protruding portion 14T is set to be lower than the lower end of the nozzle 16N of the mounting head 16 that moves in the moving region SH.

When the trolley 21 to which the parts feeder 14 is attached is connected to the base 11, or when the parts feeder 14 is attached to the trolley 21 connected to the base 11, the parts feeder 14 is in a state of being attached to the base 11. At this time, the upward protruding portion 14T of the parts feeder 14 enters the slit 51 at the corresponding position from the outside of the slit 51 (FIGS. 3 (a) → 3 (b) and 11 (a), (b)). → FIGS. 12 (a) and 12 (b)). At this time, the upward protruding portion 14T of the parts feeder 14 is guided by the tapered portion 51P provided at the outer end of the slit 51, and surely enters the slit 51.

As described above, in the present embodiment, each slit 51 is an approach path into which the upward protruding portion 14T of the parts feeder 14 enters when the parts feeder 14 is mounted on the base 11. When the upward protrusion 14T enters the slit 51, it may come into contact with the inner wall of the slit 51. However, as described above, since the feeder upper cover portion 33 is made of a stainless steel material, even if the upper protruding portion 14T comes into contact with the inner wall of the slit 51, the feeder upper cover portion 33 is not easily scratched.

In FIGS. 7A and 7B and FIGS. 12A and 12B, when the parts feeder 14 is attached to the base 11, the upward protrusion 14T included in the parts feeder 14 has a corresponding slit 51. Stay inside. As shown in FIG. 10B, in the front region of the base 11 where the nozzle 16N can be located outside the component supply port 14K of the component feeder 14, it is located above the upward protrusion 14T remaining in the slit 51. In some cases. However, as described above, since the height of the upward protruding portion 14T is set to be lower than the lower end of the nozzle 16N of the mounting head 16 that moves in the moving region SH, the nozzle 16N is set in the slit 51. Does not interfere with the upward protrusion 14T.

As described above, in the component mounting device 1 according to the present embodiment, the parts are provided on the feeder upper cover portion 33 located above the intermediate portion in the attachment / detachment direction of the parts feeder 14 attached to the base 11. When the feeder 14 is mounted on the base 11, a slit 51 is provided in which the upward projecting portion 14T extending upward from the intermediate portion of the parts feeder 14 enters. Therefore, the feeder upper cover portion 33 and the parts feeder 14 do not interfere with each other, and even when the moving area of the mounting head 16 is expanded, the existing parts feeder 14 can be used without changing the design. can.

Although the embodiments of the present invention have been described so far, the present invention is not limited to the above-mentioned ones, and various design changes can be made. For example, in the above-described embodiment, the slit 51 formed in the feeder upper cover portion 33 has a shape that opens only to the outside, but FIGS. 13 (a), 13 (b) and 14 (a), (. As shown in the first modification of b), the shape may be such that it also opens inward and penetrates in the attachment / detachment direction of the parts feeder 14 with respect to the base 11.

Further, the feeder upper cover portion 33 is not fixed to the base 11, but is integrated with the door portion 32 located above the feeder upper cover portion 33 as in the second modification shown in FIGS. 15A and 15B. (That is, it may be configured to be a part of the door portion 32). In such a configuration, when the door portion 32 is opened and closed while the parts feeder 14 is attached to the base 11, the feeder upper cover portion 33 moves relative to the base 11 (FIG. 15A → FIG. 15 (b) or FIG. 15 (b) → FIG. 15 (a), when the door portion 32 is closed, the hem portion 41 moves to a position above the parts feeder 14 while accepting the upward protruding portion 14T in the slit 51. do. At this time, in order to surely prevent the hem portion 41 from interfering with the upward protruding portion 14T, the slit 51 is provided with the parts feeder 14 in the attachment / detachment direction with respect to the base 11 as shown in FIGS. 14A and 14B. It is preferable that the shape penetrates (in the Y-axis direction).

Further, in the above-described embodiment, the approach path for entering the upward projecting portion 14T of the parts feeder 14 attached to / detached from the base 11 is a slit 51 extending in the attachment / detachment direction (Y-axis direction) of the parts feeder 14 with respect to the base 11. However, it does not necessarily have to be a slit as long as it can avoid interference with the upward protrusion 14T, and it is wide enough to allow the upward protrusion 14T of a plurality of adjacent parts feeders 14 to enter. It may be a notch or the like.

Further, of the two feeder upper cover portions 33 arranged in the front and rear of the base 11, the hem portion 41 of the feeder upper cover portion 33 arranged on the rear side has the mounting head 16 up to the limit on the rear side of the moving region. Since it does not interfere with the nozzle 16N even if it moves (FIG. 10 (a)), it is close to the parts feeder 14 like the hem 41 of the feeder upper cover portion 33 arranged on the front side (FIG. 10 (b)). You don't have to be. Therefore, for the feeder upper cover portion 33 arranged on the rear side, the height of the hem portion 41 can be arranged so as not to interfere with the upward protruding portion 14T of the parts feeder 14. In this case, the feeder upper cover portion 33 arranged on the rear side does not need to be provided with a slit 51 in the hem portion 41 and does not need to be made of a stainless steel material.

Further, in the above-described embodiment, two parts cameras 18 are provided at two positions in front of and behind the transfer conveyor 13 and the parts feeder 14 on the base 11, but the parts cameras are provided. 18 may have only one of the two front and back. Further, in the above-described embodiment, the parts feeder 14 is configured to be indirectly attached to and detached from the base 11 via a carriage 21 connected to or separated from the base 11. It is also possible to apply the parts feeder 14 to the component mounting device 1 having a configuration in which the parts feeder 14 is directly attached to the base 11 without going through the trolley 21.

Provided is a component mounting device that can be used without changing the design of an existing component feeder even when the moving area of the mounting head is expanded.
