Description

  The present invention relates to a component mounting apparatus and a component mounting apparatus head unit, and more particularly, to a component mounting apparatus and a component mounting apparatus head unit including a plurality of holding heads.

  Conventionally, a component mounting apparatus including a plurality of holding heads is known (see, for example, Patent Document 1).

  Patent Document 1 discloses an electronic component mounting apparatus (component mounting apparatus) including a mounting head (head unit) having a plurality of nozzles (holding heads). Each nozzle is configured to move up and down by a linear motor. Each nozzle has the same stroke length. Thereby, in this electronic component mounting apparatus, it is thought that each nozzle is comprised so that correspondence of components of a different size from a large component to a small component is possible.

JP 2013-254785 A

  Here, since the size of the component is different between the case where the large component is adsorbed and the case where the small component is adsorbed, the stroke length required by the nozzle differs depending on the height (thickness). For example, consider a case where a component sucked by a nozzle is transported to a substrate. In this case, in order to raise the component to a height position where the component mounted on the substrate and the component adsorbed by the nozzle do not contact during transportation, a large component requires a large stroke length, while a small component. Then, it does not require the stroke length as it is when conveying large parts. However, in the electronic component mounting apparatus described in Patent Document 1, since all the nozzles have the same stroke length, it is considered that the nozzle stroke length may become larger than necessary. For this reason, it is considered that there is a problem that the mounting head (head unit) increases in size and the weight of the mounting head (head unit) increases.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to provide a component mounting apparatus and a component mounting apparatus head unit capable of reducing the size and weight of the head unit. Is to provide.

  A component mounting apparatus according to a first aspect of the present invention includes a head unit for mounting a component on a substrate, and the head unit includes a first holding head, a second holding head, and a first holding head. The first holding head includes: a first vertical driving mechanism that drives in the vertical direction; and a second vertical driving mechanism that drives the second holding head in the vertical direction and is the same type as the first vertical driving mechanism. Has a first stroke length in the vertical direction, and the second holding head has a second stroke length in the vertical direction different from the first stroke length, and is held by the first holding head. It is comprised so that the components larger than a component may be hold | maintained.

  In the component mounting apparatus according to the first aspect of the present invention, as described above, the first holding head has the first stroke length in the vertical direction. And the 2nd holding head has the 2nd stroke length of the up-and-down direction different from the 1st stroke length. Then, the second holding head is configured to hold a component having a height higher than that of the component held by the first holding head. As a result, since the holding head has a stroke length corresponding to the height of the part, unlike the case where all the holding heads have the same stroke length, it is possible to prevent the holding head from having an unnecessarily large stroke length. it can. As a result, the head unit can be reduced in size and weight. Further, the reduction in size and weight of the head unit is also effective in improving productivity accompanying an increase in the moving speed of the head unit and reducing vibrations accompanying the movement of the head unit.

  In the component mounting apparatus according to the first aspect, preferably, the first stroke length is smaller than the second stroke length. If comprised in this way, in the 1st holding | maintenance head, since it can suppress that stroke length becomes unnecessarily large, a head unit can be reduced in size and weight by that much. In addition, since the second stroke length can be made longer than the first stroke length, it is possible to greatly move a part having a high height that is highly required to be moved largely in the vertical direction. As a result, a part having a large height can be easily handled by the second holding head.

  In this case, preferably, the first vertical drive mechanism and the second vertical drive mechanism include a linear motor, and the linear motor of the first vertical drive mechanism is driven more than the linear motor of the second vertical drive mechanism. The length is small. If comprised in this way, since the linear motor of the 1st vertical drive mechanism can be reduced in size and weight, the head unit can be reduced in size and weight accordingly. Further, by using a small vertical drive mechanism including a linear motor, the head unit can be made smaller and lighter than when a large vertical drive mechanism having a ball screw mechanism is used.

  In the component mounting apparatus according to the first aspect, preferably, the head unit includes a plurality of first holding heads and a plurality of second holding heads, the plurality of first holding heads, and the plurality of first holding heads. The two holding heads are arranged adjacent to each other. If comprised in this way, when a component is hold | maintained by the 1st holding head and the 2nd holding head, since a small component and a large component are adjacent, it suppresses that adjacent components interfere. be able to. In addition, a large component held by the second holding head may protrude to the adjacent holding head, and the holding head adjacent to the second holding head may become unusable. In this case, in this configuration, the first holding head that sucks small components cannot be used, while the second holding head that sucks large components cannot be used. Further, in the configuration in which the head unit includes a plurality of first holding heads and a plurality of second holding heads, it is possible to effectively reduce the size and weight.

  In this case, preferably, the plurality of first holding heads and the plurality of second holding heads are alternately arranged in a row. If comprised in this way, while it can suppress effectively that adjacent components interfere, it can suppress effectively that the 2nd holding head holding a big component cannot be used. .

  In the configuration in which the plurality of first holding heads and the plurality of second holding heads are arranged so as to be adjacent to each other, preferably, the plurality of first holding heads are arranged in a row, The plurality of second holding heads are arranged adjacent to the plurality of first heads arranged in a row in a direction orthogonal to the arrangement direction of the plurality of first holding heads arranged in a row. Are arranged in a shape. Even if comprised in this way, while being able to suppress effectively that adjacent components interfere, it can suppress effectively that the 2nd holding head holding a big component cannot be used. it can. Further, in this configuration, since the plurality of first holding heads and the plurality of second holding heads are arranged in a plurality of rows, the plurality of first holding heads and the plurality of second holding heads are arranged in a row. Compared to the arrangement, the length of the column can be reduced.

  The component mounting apparatus according to the first aspect preferably further includes an elevating mechanism unit that drives the entire head unit in the vertical direction. With this configuration, the first stroke length of the first holding head and the second stroke length of the second holding head are reduced by the amount that the entire head unit is driven in the vertical direction by the lifting mechanism. Can do. As a result, the head unit can be effectively reduced in size and weight.

  In this case, it is preferable to further include a control unit that controls the lowering amount of the entire head unit by the lifting mechanism unit according to the height of the component to be held. According to this configuration, the lowering amount of the entire head unit by the lifting mechanism is controlled in accordance with the height of the component to be held, so that the lowering amount of the head unit is insufficient or the lowering amount of the head unit is reduced. It can suppress becoming large too much. As a result, the component can be reliably held regardless of whether the first holding head or the second holding head is used.

  A component mounting apparatus head unit according to a second aspect of the present invention includes a first holding head, a second holding head, a first vertical driving mechanism that drives the first holding head in the vertical direction, 2 holding heads are driven in the vertical direction, and the second vertical driving mechanism of the same type as the first vertical driving mechanism is provided, the first holding head has a first stroke length in the vertical direction, The second holding head has a second stroke length in the vertical direction different from the first stroke length, and is configured to hold a component having a height higher than that of the component held by the first holding head. Has been.

  In the component mounting apparatus head unit according to the second aspect of the present invention, as described above, the first holding head has the first stroke length in the vertical direction. And the 2nd holding head has the 2nd stroke length of the up-and-down direction different from the 1st stroke length. Then, the second holding head is configured to hold a component having a height higher than that of the component held by the first holding head.

It is configured.

  With such a configuration, the head unit 3 is configured to be movable in the horizontal direction (X direction and Y direction) on the base 1. Thereby, the head unit 3 can move, for example, above the tape feeder 10 to suck the component E supplied from the tape feeder 10. Further, the head unit 3 can move, for example, above the board P fixed at the mounting work position M, and mount the sucked component E on the board P. Further, the head unit 3 can move, for example, above the component recognition lower camera 6 and pick up the picked-up component E by the component recognition lower camera 6.

  The component recognition lower camera 6 is configured to take an image of the component E attracted to the head unit 3 prior to the mounting of the component E. The component recognition lower camera 6 is fixed on the upper surface of the base 1 and is configured to image the component E attracted to the head unit 3 from below the component E (Z2 direction). This imaging result is acquired by the control unit 9. Then, based on the acquired imaging result of the part E, the suction state (rotational posture and suction position) of the part E is acquired by the control unit 9.

  The board recognition camera 7 is configured to take an image of a position recognition mark (fiducial mark) FM attached to the board P prior to mounting the component E. The position recognition mark FM is a mark for acquiring the position of the substrate P. In the substrate P shown in FIG. 1, a pair of position recognition marks FM are attached to the lower right position and the upper left position of the substrate P. The imaging result of the position recognition mark FM is acquired by the control unit 9. Then, based on the imaging result of the acquired position recognition mark FM, the accurate position and posture of the substrate P fixed by a substrate fixing mechanism (not shown) is acquired by the control unit 9.

  The control unit 9 includes a CPU (Central Processing Unit) and is configured to control the operation of the component mounting apparatus 100. The control unit 9 controls the substrate transport unit 2, the X-axis motor 42, the Y-axis motor 53, the linear motor 70 and the rotation drive mechanism 80 described later according to the production program, and sucks the component E supplied from the tape feeder 10. And the component E is mounted on the board P.

(Head unit configuration)
Next, the configuration of the head unit 3 will be described with reference to FIGS. As shown in FIGS. 2 and 3, the head unit 3 includes ten suction heads 60, ten linear motors 70, and a rotation drive mechanism 80.

  Each suction head 60 is configured to hold the component E supplied from the tape feeder 10 by suction. Here, in the first embodiment, the ten suction heads 60 include five small component compatible suction heads 61 and five large component compatible suction heads 62. The small component-corresponding suction head 61 is an example of the “first holding head” in the claims. The large component-corresponding suction head 62 is an example of the “second holding head” in the claims.

  Each small component-corresponding suction head 61 has a vertical stroke length D1 as shown in FIG. The stroke length D1 is a length from the upper end position H1 where the small component-corresponding suction head 61 is raised most up to the lower end position H2 where the small component-corresponding suction head 61 is lowered most. That is, each small component-corresponding suction head 61 is configured to be movable in the vertical direction from the upper end position H1 to the lower end position H2. In the first embodiment, the stroke length D1 of the small component-corresponding suction head 61 is smaller than the stroke length D2 described later of the large component-corresponding suction head 62. The stroke length D1 is an example of the “first stroke length” in the claims.

  As shown in FIG. 3, each small component-corresponding suction head 61 is configured to suck a small component E1 having a small height (thickness). That is, in the component mounting apparatus 100, each small component-corresponding suction head 61 is responsible for sucking the small component E1. On the other hand, in the component mounting apparatus 100, each small component-corresponding suction head 61 does not take charge of suction of a large component E2 described later.

  Each small component-corresponding suction head 61 has a shaft portion 61a and a suction nozzle 61b. The shaft portion 61a is formed so as to extend along the vertical direction. The shaft portion 61a has an upper end (Z1 side) end portion connected to a linear motor 71 described later. The shaft portion 61a is provided with a suction nozzle 61b at the lower end (Z2 side). In the component mounting apparatus 100, a negative pressure is supplied to the suction nozzle 61b by a vacuum generator (not shown). Each small component-corresponding suction head 61 is configured to be capable of sucking the small component E1 by the negative pressure supplied to the suction nozzle 61b.

  Each large component-corresponding suction head 62 has a stroke length D2 in the vertical direction, as shown in FIG. The stroke length D2 is a length from the upper end position H3 where the large component-corresponding suction head 62 is most raised to the lower end position H4 where the large component-corresponding suction head 62 is most lowered. That is, each large component-corresponding suction head 62 is configured to be movable in the vertical direction from the upper end position H3 to the lower end position H4. The stroke length D2 is an example of the “second stroke length” in the claims.

  As shown in FIG. 3, each large component-corresponding suction head 62 is configured to suck a large component E2 having a height (thickness) larger than that of the small component E1. Further, each large component-compatible suction head 62 is configured to suck the small component E1 in addition to the large component E2. That is, in the component mounting apparatus 100, each large component-compatible suction head 62 takes charge of suction of both the small component E1 and the large component E2.

  Each large component-corresponding suction head 62 has a shaft portion 62a and a suction nozzle 62b. The shaft portion 62a is formed so as to extend along the vertical direction. The shaft portion 62a has an upper end (Z1 side) end portion connected to a linear motor 72 described later. The shaft portion 62a is provided with a suction nozzle 62b at the lower end (Z2 side). In the component mounting apparatus 100, a negative pressure is supplied to the suction nozzle 62b by a vacuum generator (not shown). Each large component-corresponding suction head 62 is configured to be able to suck the small component E1 or the large component E2 by the negative pressure supplied to the suction nozzle 62b.

  In the component mounting apparatus 100, the upper end position H1 of each small component-corresponding suction head 61 and the upper end position H3 of each large component-corresponding suction head 62 are different height positions. Specifically, the upper end position H3 of each large component-corresponding suction head 62 is higher than the upper end position H1 of each small component-corresponding suction head 61 by ΔD1. That is, in the component mounting apparatus 100, the upper end of the component E can be raised to a higher position in the large component compatible suction head 62 than in the small component compatible suction head 61.

  As a result, the large component-corresponding suction head 62 raises the large component E2 to a height position at which the component E mounted on the substrate P and the large component E2 being conveyed do not contact, for example, when the large component E2 is conveyed. It is possible to make it. For example, even when the height position at which the component recognition side camera 8 images the component E is high, the large component E2 can be raised to the height position at which the component recognition side camera 8 images the component E. Is possible. Therefore, in the component mounting apparatus 100, the large component-corresponding suction head 62 takes charge of both suction of the large component E2 and suction of the small component E1 smaller than the large component E2.

  On the other hand, in the component mounting apparatus 100, when the small component-corresponding suction head 61 takes charge of sucking the large component E2, for example, the height position where the component E mounted on the substrate P and the large component E2 being transported do not contact each other. Until the large component E2 cannot be raised, or the large component E2 cannot be raised to a height position where the component recognition side camera 8 images the component E. For this reason, in the component mounting apparatus 100, the small component-corresponding suction head 61 is responsible for suction of the small component E1, but is not responsible for suction of the large component E2. In the first embodiment, the stroke length D1 of the small component-compatible suction head 61 is set to the stroke length D1 that is not necessary because the small component-compatible suction head 61 is not responsible for suction of the large component E2. It is possible to make it smaller than the stroke length D2.

  Moreover, in the component mounting apparatus 100, the lower end position H2 of each small component corresponding suction head 61 and the lower end position H4 of each large component corresponding suction head 62 are the same height position. That is, the small component-corresponding suction head 61 and the large component-corresponding suction head 62 can lower the component E to the same height position. Since the small component E1 is lower than the large component E2 when the small component E1 is mounted, the small component corresponding suction head 61 is lowered so that the large component E2 suction head 62 is lowered. Lower than position.

  In the first embodiment, as shown in FIGS. 2 and 3, the five small-component suction heads 61 and the five large-component suction heads 62 are arranged adjacent to each other. . Specifically, five small component-corresponding suction heads 61 and five large component-corresponding suction heads 62 are alternately arranged in a row. In addition, the five small component-corresponding suction heads 61 and the five large component-corresponding suction heads 62 are arranged in rows at equal distances.

  The ten linear motors 70 are provided so as to correspond to the ten suction heads 60, respectively. Each linear motor 70 is configured to drive the corresponding suction head 60 in the vertical direction.

  In the first embodiment, the ten linear motors 70 correspond to the five linear motors 71 corresponding to the five small-component suction heads 61 and the five large-component suction heads 62, respectively. And five linear motors 72. The linear motor 71 and the linear motor 72 are the same type of vertical drive mechanism. The linear motor 71 is an example of the “first vertical drive mechanism” in the claims. The linear motor 72 is an example of the “second vertical drive mechanism” in the claims.

  Each linear motor 71 has a drive length corresponding to the stroke length D1 of the small component-compatible suction head 61. The linear motor 71 has a stroke length D1 and is configured to be able to drive the suction head 61 for small parts in the vertical direction.

  Each linear motor 72 has a drive length corresponding to the stroke length D2 of the suction head 62 for large parts. That is, in the first embodiment, each linear motor 71 has a smaller driving length than each linear motor 72. Since each drive length is small, each linear motor 71 is smaller than each linear motor 72. The linear motor 72 has a stroke length D2 and is configured to be able to drive the suction head 62 for large parts in the vertical direction.

  The rotation drive mechanism 80 is configured to rotate each suction head 60 in the vertical direction (Z direction).

  The rotation drive mechanism 80 includes a first rotation drive mechanism 81 that rotates the five suction heads 60 on the X2 side, and a second rotation drive mechanism 82 that rotates the five suction heads 60 on the X1 side. The five suction heads 60 on the X2 side include two suction heads 61 for small components and three suction heads 62 for large components. Further, the five suction heads 60 on the X1 side include three small component-compatible suction heads 61 and two large component-compatible suction heads 62.

  The first rotation drive mechanism 81 has a drive motor 81a and a belt pulley mechanism 81b. The drive motor 81a is configured to generate a driving force for rotating the five suction heads 60 on the X2 side. The belt pulley mechanism 81b is configured to transmit the driving force generated by the driving motor 81a to the five suction heads 60 on the X2 side. The five suction heads 60 on the X2 side are configured to rotate in the vertical direction by the driving force of the driving motor 81a transmitted through the belt pulley mechanism 81b.

  The second rotation drive mechanism 82 includes a drive motor 82a and a belt pulley mechanism 82b. The drive motor 82a is configured to generate a drive force for rotating the five suction heads 60 on the X1 side. The belt pulley mechanism 82b is configured to transmit the driving force generated by the driving motor 82a to the five suction heads 60 on the X1 side. The five suction heads 60 on the X1 side are configured to rotate in the vertical direction by the driving force of the driving motor 82a transmitted through the belt pulley mechanism 82b.

(Effect of 1st Embodiment)
In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, the small component-corresponding suction head 61 has the stroke length D1 in the vertical direction. The large component-corresponding suction head 62 has a vertical stroke length D2 different from the stroke length D1. The large component-corresponding suction head 62 is configured to suck a component (large component E2) having a height higher than that of the component sucked (held) by the small component-corresponding suction head 61. Thereby, since the suction head 60 has a stroke length corresponding to the size of the part, unlike the case where all the suction heads 60 have the same stroke length, it is possible to suppress the stroke length of the suction head 60 from becoming unnecessarily large. can do. As a result, the head unit 3 can be reduced in size and weight. Further, the reduction in size and weight of the head unit 3 is also effective in improving productivity accompanying an increase in the moving speed of the head unit 3 and reducing vibrations accompanying the movement of the head unit 3.

  In the first embodiment, as described above, the stroke length D1 is smaller than the stroke length D2. Thereby, in the small component-corresponding suction head 61, it is possible to prevent the stroke length from becoming unnecessarily large, and accordingly, the head unit 3 can be reduced in size and weight. Further, since the stroke length D2 can be made larger than the stroke length D1, a part having a large height (large part E2) that is highly required to be moved in the vertical direction can be largely moved in the vertical direction. As a result, a larger component (large component E2) can be easily handled in the large component compatible suction head 62.

  In the first embodiment, as described above, the linear motor 71 has a smaller driving length than the linear motor 72. Thereby, since the linear motor 71 can be reduced in size and weight, the head unit 3 can be reduced in size and weight accordingly. Further, by using a small vertical drive mechanism including the linear motor 70, the head unit 3 can be made smaller and lighter than when a large vertical drive mechanism having a ball screw mechanism is used.

  In the first embodiment, as described above, a plurality (five) of small component-corresponding suction heads 61 and a plurality (five) of large component-corresponding suction heads 62 are disposed adjacent to each other. Thereby, when the small component E1 is adsorbed by the small component-corresponding suction head 61 and the large component E2 is attracted by the large component-corresponding suction head 62, the small component E1 and the large component E2 are adjacent to each other. Interference between parts can be suppressed. In addition, in a configuration in which the head unit 3 includes a plurality of small component-compatible suction heads 61 and a plurality of large component-compatible suction heads 62, it is possible to effectively reduce the size and weight.

  In the first embodiment, as described above, the plurality of small component-compatible suction heads 61 and the plurality of large component-compatible suction heads 62 are alternately arranged in a row. Thereby, it can suppress effectively that adjacent components interfere.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. 1 and 5 to 7. In the second embodiment, in addition to the configuration of the first embodiment, an example in which an elevating mechanism unit that drives the entire head unit in the vertical direction is provided will be described. In addition, about the structure same as the said 1st Embodiment, the same code | symbol is attached | subjected and shown in the figure, and the description is abbreviate | omitted.

(Configuration of component mounting device)
The component mounting apparatus 200 according to the second embodiment of the present invention includes the head unit 103, the control unit 109, and the lifting mechanism unit 190 as shown in FIGS. 1, 5, and 6. This is different from the component mounting apparatus 100 of the embodiment. The head unit 103 is an example of a “component mounting apparatus head unit” in the claims.

  In the second embodiment, the component mounting apparatus 200 is provided with an elevating mechanism 190 as shown in FIGS. 5 and 6. The lifting mechanism 190 is configured to drive the entire head unit 103 in the vertical direction.

  As shown in FIG. 7, the head unit 103 has a vertical stroke length D3. The stroke length D3 is a length from the upper end position H5 where the head unit 103 is most raised to the lower end position H6 where the head unit 103 is most lowered. That is, the head unit 103 is configured to be movable in the vertical direction from the upper end position H5 to the lower end position H6 by the elevating mechanism 190.

  In the second embodiment, the stroke length D3 of the suction head 161 corresponding to a small component described later and the stroke length D5 of the suction head 162 corresponding to a large component described later are reduced by the amount that the head unit 103 is driven in the vertical direction with the stroke length D3. It becomes possible to do. The small component-corresponding suction head 161 is an example of the “first holding head” in the claims. The large component-corresponding suction head 162 is an example of the “second holding head” in the claims. In the second embodiment, the stroke length D3 is larger than the stroke length D4 of the small component-compatible suction head 161 and the stroke length D5 of the large component-compatible suction head 162. Thereby, the stroke length D4 of the suction head 161 for small parts and the stroke length D5 of the suction head 162 for large parts can be made sufficiently small.

  In the second embodiment, the stroke length D4 of the small component compatible suction head 161 and the stroke length D5 of the large component compatible suction head 162 are reduced, and the stroke length D3 of the head unit 103 is used to reduce the stroke length D4 of the small component compatible suction head 161. The amount of vertical movement with the large component compatible suction head 162 is ensured. As a result, for example, when the component E is transported by the small component compatible suction head 161 and the large component compatible suction head 162, the component E mounted on the substrate P and the height of the component E being transported are not touched. E can be raised. Further, for example, even when the height position at which the component recognition side camera 8 images the component E is high, the small component-corresponding suction head 161 and the large size are captured to the height position at which the component recognition side camera 8 images the component E. The component E sucked by the component-corresponding suction head 162 can be raised. Further, the linear motor 71 and the linear motor 72 according to the second embodiment are equivalent to the linear motor 71 and the linear motor 72 according to the first embodiment because the stroke lengths of the small component-compatible suction head 161 and the large component-compatible suction head 162 are reduced. Compared to, it is downsized.

  The lifting mechanism 190 has a drive length corresponding to the stroke length D3 of the head unit 103. The elevating mechanism 190 has a stroke length D3 and is configured to drive the head unit 103 in the vertical direction. The lifting mechanism 190 is a vertical drive mechanism having a ball screw mechanism. By using the vertical drive mechanism (elevating mechanism 190) having a ball screw mechanism, the heavy head unit 103 can be easily driven in the vertical direction.

  As shown in FIGS. 5 and 6, the elevating mechanism 190 includes a drive motor 191, a ball screw shaft 192, and a pair of rails 193.

  The drive motor 191 is configured to generate a driving force for rotating the ball screw shaft 192. The ball screw shaft 192 is configured to rotate about the vertical direction (Z direction) by the driving force of the drive motor 191. A pair of rail part 193 is formed so that it may extend along an up-down direction. Further, the head unit 103 is provided with a ball nut 103 b that engages with the ball screw shaft 192. When the ball screw shaft 192 is rotated by the drive motor 191, the elevating mechanism portion 190 moves the head unit 103 along the pair of rail portions 193 along the stroke length D <b> 3 together with the ball nut 103 b that engages with the ball screw shaft 192. It is configured to move in the vertical direction.

  In the second embodiment, the head unit 103 includes five small component-corresponding suction heads 161 and five large component-corresponding suction heads 162, as shown in FIG.

  In the head unit 103 of the second embodiment, the stroke lengths of the small component-corresponding suction head 161 and the large component-corresponding suction head 162 are the same as in the first embodiment because the head unit 103 is driven vertically by the lifting mechanism 190 with the stroke length D3. This is different from the head unit 3 of the first embodiment in that it is smaller than the stroke length of the suction head 61 for small components and the suction head 62 for large components. The head unit 103 according to the second embodiment is the same as the head according to the first embodiment in that the upper end position of the suction head 161 for small parts and the upper end position of the suction head 162 for large parts are the same height. Different from unit 3.

  Each small component-corresponding suction head 161 has a vertical stroke length D4, as shown in FIG. The stroke length D4 is, for example, the lower end at which the head unit 103 descends most and the small component-corresponding suction head 161 descends most from the height position H7 where the head unit 103 descends most and the small component-corresponding suction head 161 rises most. The length to the position H8. In the second embodiment, the small component-corresponding suction heads 161 are vertically moved from the upper end position H5 of the head unit 103 (the upper end position of the small component-corresponding suction head 161) to the lower end position H8 of the small component-corresponding suction head 161. It is configured to be movable. Moreover, the stroke length D4 of the suction head 161 for small parts is smaller than the stroke length D5 described later of the suction head 162 for large parts. The stroke length D4 is an example of the “first stroke length” in the claims.

  Each large component-corresponding suction head 162 has a vertical stroke length D5. The stroke length D5 is, for example, the lower end at which the head unit 103 descends most and the large component-corresponding suction head 162 descends most from the height position H9 where the head unit 103 descends most and the large component-corresponding suction head 162 rises most. It is the length to the position H10. In the second embodiment, each large component-corresponding suction head 162 is vertically moved from the upper end position H5 of the head unit 103 (the upper end position of the large-component suction head 162) to the lower end position H10 of the large-component suction head 162. It is configured to be movable. The stroke length D5 is an example of the “second stroke length” in the claims.

  In the second embodiment, the stroke length D5 of the large component-corresponding suction head 162 is larger than the height (thickness) of the large component E2. As a result, it is possible to take out the large component E2 arranged in the recess in the component supply tape of the tape feeder 10 from the recess only by the upward stroke of the large component-corresponding suction head 162. Therefore, in the component mounting apparatus 200, the large component-corresponding suction head 162 takes charge of both the suction of the large component E2 and the suction of the small component E1 smaller than the large component E2.

  In the second embodiment, the stroke length D4 of the adsorption head 161 for small components is smaller than the height (thickness) of the large component E2. For this reason, the large component E2 disposed in the recess in the component supply tape of the tape feeder 10 cannot be taken out of the recess only by the upward stroke of the small component-corresponding suction head 161. Therefore, in the component mounting apparatus 200, the small component-corresponding suction head 161 takes charge of sucking the small component E1, but does not take charge of sucking the large component E2.

  Moreover, in the component mounting apparatus 200, the upper end position (H5) of each small component corresponding suction head 161 and the upper end position (H5) of each large component corresponding suction head 162 are the same height position.

  Here, as shown in FIG. 5, consider a case where a large-sized component E <b> 2 having a large width that protrudes to the adjacent small-component-compatible suction head 161 is handled. In this case, if the upper end position of each small component-corresponding suction head 161 is lower than the upper end position of each large component-corresponding suction head 162 as in the first embodiment, the large component-corresponding suction head 162 is raised to the upper end position. When trying to do so, the adjacent small component-compatible suction head 161 interferes with the large component E2. For this reason, the large component-corresponding suction head 162 can only be raised to a height position where the adjacent small component-corresponding suction head 161 and the large component E2 do not interfere with each other. Inconvenience occurs.

  In the second embodiment, since the upper end position (H5) of each small component-corresponding suction head 161 and the upper end position (H5) of each large component-corresponding suction head 162 are the same height position, the large component-corresponding suction head. When the 162 is raised to the upper end position, it is possible to prevent the adjacent small component-corresponding suction head 161 and the large component E2 from interfering with each other. As a result, the large component compatible suction head 162 can handle the large component E2 having a large width so as to protrude to the adjacent small component compatible suction head 161.

  Moreover, in the component mounting apparatus 200, the lower end position H8 of each small component corresponding suction head 161 and the lower end position H10 of each large component corresponding suction head 162 are different height positions. Specifically, the lower end position H10 of each large component-corresponding suction head 162 is lower by ΔD2 than the lower end position H8 of each small component-corresponding suction head 161. Since the small component E1 is lower than the large component E2 when the small component E1 is mounted, the small component corresponding suction head 161 is lowered so that the large component E2 suction head 62 is lowered. Lower than position.

  Further, in the second embodiment, the control unit 109 is configured to control the lowering amount of the entire head unit 103 by the lifting mechanism unit 190 according to the height (thickness) of the component E to be sucked. Specifically, the control unit 109 is configured to perform control to increase the descending amount of the entire head unit 103 by the lifting mechanism unit 190 as the height (thickness) of the component E decreases. .

  For example, when the small component E1 is picked up by the small component-corresponding suction head 161, the control unit 109, compared to the case where the large component E2 is picked up by the large component-corresponding suction head 162, the head unit 103 by the lifting mechanism 190. Control is performed to increase the total descending amount.

  In addition, the control unit 109 lowers the entire head unit 103 by the lifting mechanism 190 and then lowers the suction head 161 for small parts or the suction head 162 for large parts to handle the suction head 161 for small parts or for the large parts. The suction head 162 is configured to control the suction of the component E.

  In addition, after the component E is sucked, the control unit 109 is configured to perform the raising of the small component-corresponding suction head 161 and the large component-corresponding suction head 162 and the lifting of the head unit 103 by the lifting mechanism 190 in parallel. Has been. And the control part 109 is comprised so that the components E attracted | sucked by the small component corresponding | compatible adsorption head 161 or the large component corresponding | compatible adsorption head 162 may be conveyed to the board | substrate P. FIG.

  In addition, the other structure of 2nd Embodiment is the same as that of the said 1st Embodiment.

(Effect of 2nd Embodiment)
In the second embodiment, the following effects can be obtained.

  In the second embodiment, as described above, the small component-corresponding suction head 161 has the vertical stroke length D4. The large component-corresponding suction head 162 has a vertical stroke length D5 different from the stroke length D4. Thereby, similarly to the first embodiment, the head unit 103 can be reduced in size and weight.

  In the second embodiment, as described above, the component mounting apparatus 200 is provided with the lifting mechanism 190 that drives the entire head unit 103 in the vertical direction. As a result, the stroke length D4 of the suction head 161 for small parts and the stroke length D5 of the suction head 162 for large parts can be reduced by driving the entire head unit 103 in the vertical direction by the lifting mechanism 190. As a result, the head unit 103 can be effectively reduced in size and weight.

  Further, in the second embodiment, as described above, the control unit 109 that controls the descending amount of the entire head unit 103 by the lifting mechanism 190 according to the height of the component E to be sucked in the component mounting apparatus 200 is provided. Provide. As a result, the lowering amount of the entire head unit 103 by the elevating mechanism 190 is controlled according to the height of the component E to be sucked, so that the lowering amount of the head unit 103 is insufficient or the lowering amount of the head unit 103 Can be prevented from becoming excessively large. As a result, the component E can be reliably sucked regardless of whether the small component-corresponding suction head 161 or the large component-corresponding suction head 162 is used.

  In the second embodiment, as described above, a plurality (five) of small component-corresponding suction heads 161 and a plurality (five) of large component-corresponding suction heads 162 are arranged adjacent to each other. As a result, when the small component E1 is adsorbed by the small component compatible adsorption head 161 and the large component E2 is adsorbed by the large component compatible adsorption head 162, the small component E1 and the large component E2 are adjacent to each other. Interference between parts can be suppressed. In addition, as described above, the large component E2 sucked by the large component-corresponding suction head 162 may protrude to the adjacent suction head 60, and the suction head 60 adjacent to the large-component-compatible suction head 162 may become unusable. In this case, in this configuration, it is possible to suppress the use of the large component-corresponding suction head 162 that sucks the large component E2 while the small component-compatible suction head 161 that sucks the small component E1 cannot be used. This effect is particularly effective when both the small component E1 and the large component E2 are handled by the large component compatible suction head 162. Further, when the head unit 103 includes a plurality of small component-compatible suction heads 161 and a plurality of large component-compatible suction heads 162, the effect of further reducing the size and weight can be obtained.

  In the second embodiment, as described above, a plurality of small component-compatible suction heads 161 and a plurality of large component-compatible suction heads 162 are alternately arranged in a row. Thereby, it can suppress effectively that adjacent components interfere, and it can suppress effectively that the large component corresponding | compatible adsorption head 162 which adsorb | sucks the large component E2 cannot be used.
