The opening 61a has an inner diameter slightly larger than the maximum width of the nozzle body 50 (the width W1 of the intermediate portion 53) so that the nozzle body 50 can be inserted.

  In addition, four engaging pieces 65 (see FIG. 8B) are integrally formed on the tip portion 61 at the tip portion 61. As shown in FIG. 8A, each engaging piece 65 is formed so as to protrude inward after protruding from the lower end surface of the distal end portion 61 toward the distal end side (Z2 direction). As a result, each engagement piece 65 protrudes inward from the peripheral edge of the distal end portion 61 when viewed from the axial front end side (Z2 direction side) as shown in FIG. 8B, and has a circular opening 61a and a shaft. It partially overlaps the direction. These engagement pieces 65 have a function of engaging the nozzle body 50 and holding the nozzle body 50 in the holder portion 60. That is, each engagement piece 65 includes an inner upper surface 65a (see FIG. 8A) that engages with the axial engagement portion 54 of the nozzle body 50 in the axial direction (Z direction), and the rotation direction engagement portion 57. It integrally includes a side end face 65b to be engaged. The inner upper surface 65a contacts the axial engagement portion 54 in the contact region 65c shown in FIG. 8B and 11B, the contact region 65c is illustrated on the lower surface side of the engagement piece 65 for the sake of explanation, but the contact region 65c is actually the engagement piece 65. Is the opposite surface (inner upper surface 65a) side.

  As shown in FIG. 8 (B), the four engagement pieces 65 are respectively arranged at the four corners of the opening 61a when viewed from the axial front end side (Z2 direction side), and each set of two in the E direction ( The side end faces 65b are provided so as to face each other in the E direction. The opening 61a of the holder portion 60 includes a first groove portion 61b having a first interval D1 between the engagement pieces 65 and extending in the E direction by the four engagement pieces 65, and a second interval D2 smaller than the first interval D1. And the second groove 61c extending in the F direction is partitioned into an opening shape that crosses the cross. That is, the first groove 61b in the E direction and the second groove 61c in the F direction are orthogonal to each other.

  As shown in FIGS. 8A and 8B, the accommodating portion 62 is a cylindrical portion formed so as to extend upward from the distal end portion 61 and to be continuous from the opening 61a with a constant inner diameter. . The inside of the housing portion 62 is a housing space 62 a for the nozzle body 50 and the spring member 70. A support surface 62b is formed at the inner upper end of the accommodation space 62a by reducing the inner diameter of the accommodation space 62a. The support surface 62b functions as a spring receiving portion with which the upper end portion of the spring member 70 (see FIG. 4) attached to the shaft-like portion 56 abuts.

  The bearing part 63 is provided so as to continuously extend upward from the upper part of the housing part 62. The bearing portion 63 is formed in a cylindrical shape having an inner diameter d <b> 1 that substantially matches the outer diameter of the shaft-like portion 56 of the nozzle body 50. By fitting the shaft-like portion 56 to the bearing portion 63, the passage portion 64a (part of the air passage) on the upper side of the bearing portion 63 and the inside of the lower accommodating portion 62 are in a non-communication state. Air flow is blocked. Therefore, as shown in FIG. 4, the passage portion 64 a on the upper side of the holder portion 60 and the air passage 51 of the nozzle body 50 communicate with each other by the fitting of the shaft-like portion 56 and the bearing portion 63, and the suction nozzle 5. An air passage extending up and down is formed. The bearing portion 63 has a function of guiding sliding of the nozzle body 50 in the axial direction (Z direction) and rotation around the central axis by fitting with the shaft-like portion 56 of the nozzle body 50.

  As shown in FIG. 8A, the upper cylindrical portion 64 is a cylindrical portion that continues upward from the bearing portion 63. Inside the upper cylinder portion 64, a passage portion 64a having a constant inner diameter and communicating with the air passage 51 of the nozzle body 50 is provided. The passage portion 64 a is configured such that the tip of the nozzle shaft 42 of the component mounting head 41 is inserted when the suction nozzle 5 is mounted on the component mounting head 41. Thereby, the pressure from the pressure generator (not shown) of the head unit 4 described above is supplied to the suction port 52a of the nozzle portion 52 via the nozzle shaft 42, the passage portion 64a and the air passage 51 of the nozzle body 50 ( (See FIG. 11A). In addition, a pair of engaging convex portions 64b are formed on the outer peripheral side of the upper cylindrical portion 64, and the pair of engaging convex portions 64b engage with a clamp member (not shown) of the component mounting head 41, thereby attracting. The nozzle 5 is mounted on the component mounting head 41.

  In the state where the nozzle shaft 42 is inserted into the passage portion 64a of the upper cylindrical portion 64, the nozzle body 50 abuts on the tip of the nozzle shaft 42 when the nozzle body 50 is moved upward by the first distance D3. The upper movement is locked. For this reason, in a state in which the suction nozzle 5 is attached to the component mounting head 41, the nozzle body 50 can move within the range of the first distance D3.

  As shown in FIGS. 4 and 9A, the spring member 70 is a compression coil spring, and is attached to the shaft portion 56 by inserting the shaft portion 56 of the nozzle body 50. The spring member 70 is disposed on the outer peripheral side of the shaft-like portion 56 of the nozzle body 50 and on the inner peripheral side (within the accommodating space 62 a) of the accommodating portion 62 of the holder portion 60. The spring member 70 urges the nozzle body 50 (flange portion 55) toward the distal end side (Z2 direction) and presses the axial engagement portion 54 against the inner upper surface 65a of the engagement piece 65 to maintain the engagement state. It has a function to make it. Further, when the tip of the nozzle body 50 comes into contact with the component 10 or the like during the mounting operation, the nozzle body 50 compresses the spring member 70 while the first distance D3 (FIG. 11) from the tip portion 61 side of the holder portion 60. It is possible to move upward (Z1 direction) within the range of (A). As a result, the spring member 70 has a buffer function (so-called buffing function) that relieves an impact when the suction nozzle 5 is in contact.

  Next, the engagement structure between the nozzle body 50 and the holder portion 60 will be described in detail.

  As shown in FIGS. 9A and 9B, the nozzle body 50 includes a first width W3 of the axial engagement portion 54 in the B direction extending in the E direction in the opening 61a of the holder portion 60. It is configured to be equal to or smaller than the first interval D1 of the groove portion 61b and larger than the second interval D2 of the second groove portion 61c extending in the F direction (see FIG. 10B). For this reason, when the nozzle body 50 is inserted into the holder portion 60 at a first rotation angle in which the A direction of the axial engagement portion 54 coincides with the E direction in which the first groove portion 61b extends, the axial engagement portion having the width W3. 54 can pass through the first groove 61b of the first interval D1 without engaging with the engaging piece 65.

  Further, in the state where the axial engagement portion 54 is disposed inside the holder portion 60, the A direction of the axial engagement portion 54 is set to the second rotation angle that matches the F direction in which the second groove portion 61c extends. In this case, as shown in FIGS. 10A and 10B, the axial engagement portion 54 having the width W3 cannot pass through the second groove portion 61c having the second distance D2, and both sides of the second groove portion 61c. Is engaged with the engagement piece 65 (see FIG. 11A). At this time, as shown in FIGS. 11A and 11B, the lower surface 54a of the axial engagement portion 54 and the inner upper surface 65a of the engagement piece 65 are in contact (contact regions 54b and 65c). Thus, the axial engagement portion 54 and the engagement piece 65 are engaged in the axial direction. As a result, the nozzle body 50 is held in the holder portion 60 in the axial direction.

  As shown in FIGS. 10A and 10B, the pair of rotation direction engaging portions 57 (intermediate portion 53) of the nozzle body 50 has a width W2 between both side surfaces of the intermediate portion 53 in the B direction. Is formed to be substantially equal to the second distance D2 of the second groove 61c extending in the F direction. As a result, the intermediate portion 53 slides in the axial direction on the second groove portion 61c having the second interval D2 at a second rotation angle in which the A direction coincides with the F direction in which the second groove portion 61c extends. It is configured to be movably fitted. As a result, as shown in FIGS. 11A and 11B, the second engagement angle 54 and the engagement piece 65 are engaged with each other in the axial direction at the second rotation angle. The side end surfaces 65b of the engagement pieces 65 on both sides of the groove 61c are in contact with the pair of rotation direction engagement parts 57 (contact areas 57a and 65d), respectively. Engage in the direction of rotation.

  The intermediate portion 53 formed with the rotation direction engaging portion 57 has a length L in the axial direction. For this reason, the nozzle body 50 has the second distance D4 until the rotation direction engagement portion 57 is disposed at a position higher than the engagement piece 65 in the engagement state at the second rotation angle (FIG. 10A). If it is not inserted into the holder part 60 only (see), the engagement between the rotation direction engaging part 57 and the engaging piece 65 (side end face 65b) is not released. That is, in order to rotate the holder part 60 from the second rotation angle to the first rotation angle, it is necessary to insert the nozzle body 50 into the holder part 60 from the engaged state by the second distance D4.

  Here, as described above, the nozzle main body 50 is within the range of the first distance D3 until it comes into contact with the tip of the nozzle shaft 42 in a state where the nozzle shaft 42 is inserted into the passage portion 64a of the upper cylindrical portion 64. It can move upward. In the present embodiment, the second distance D4 for releasing the rotation direction engagement between the rotation direction engaging portion 57 and the engagement piece 65 (side end surface 65b) is larger than the first distance D3. Is set. Therefore, in the state where the suction nozzle 5 is attached to the component mounting head 41, even if the nozzle body 50 is moved upward to the upper limit of movement (first distance D3), the rotation direction engaging portion 57 and the engaging piece 65 (side) Since the engagement with the end face 65b) is not released, the nozzle body 50 cannot be rotated.

  In addition, since the engagement between the rotation direction engagement portion 57 and the engagement piece 65 is released by inserting the nozzle body 50 into the holder portion 60 by the second distance D4, the engagement release state (first rotation angle) When the nozzle body 50 is rotated from the first rotation angle to the second rotation angle even when the engagement state (second rotation angle) is changed to the second rotation angle, the nozzle shaft 42 is not inserted. Therefore, it is necessary to insert the nozzle body 50 into the holder portion 60 by the second distance D4.

  Next, with reference to FIGS. 9-11, the assembly and disassembly method of the suction nozzle 5 by this embodiment is demonstrated.

  When assembling the suction nozzle 5, first, as shown in FIGS. 9A and 9B, the A direction of the nozzle body 50 is set in the state where the spring member 70 is attached to the shaft-like portion 56. The nozzle body 50 is inserted into the holder portion 60 at a first rotation angle that matches the E direction in which the one groove portion 61b extends. Thereby, the axial direction engaging part 54 passes the 1st groove part 61b of the opening 61a, and enters the inside of the accommodating part 62 (inside the accommodating space 62a). At this time, since the upper end portion of the spring member 70 contacts the support surface 62b, the nozzle body 50 is pushed upward so as to overcome the repulsive force of the spring member 70.

  When the nozzle body 50 is inserted into the holder portion by the second distance D4 while maintaining the first rotation angle, the rotation direction engagement portion 57 passes through the position of the engagement piece 65 and is disposed above. In this state, as shown in FIGS. 10 (A) and 10 (B), the nozzle body 50 is moved from the first rotation angle to the second rotation angle in which the A direction coincides with the F direction in which the second groove 61c extends. Rotate 90 degrees.

  Finally, the compression force of the spring member 70 is restored by releasing the upward pushing force of the nozzle body 50 in the state of the second rotation angle. As a result, the nozzle main body 50 is pushed back (moves downward) by the second distance D4. At this time, the intermediate portion 53 of the nozzle body 50 is fitted into the second groove portion 61c, and the pair of rotational direction engaging portions 57 are engaged with the engaging pieces 65 in the rotational direction, respectively. As shown in FIGS. 11 (A) and 11 (B), when the nozzle body 50 is moved to the tip side by the second distance D4 by the biasing force of the spring member 70, the axial engagement portion 54 of the nozzle body 50 is moved. It abuts on the engagement piece 65 and is engaged in the axial direction. Further, the engagement in the rotation direction between the pair of rotation direction engaging portions 57 and the engagement piece 65 is maintained as it is. As a result, the nozzle body 50 is held by the holder portion 60 in a state where the nozzle body 50 is engaged with the holder portion 60 in the axial direction and the rotational direction. As a result, the suction nozzle 5 can be inserted into the nozzle shaft 42 and the suction nozzle 5 can be mounted on the component mounting head 41 as shown in FIGS.

  When disassembling the suction nozzle 5 when cleaning the suction nozzle 5, first, the suction nozzle 5 is removed from the component mounting head 41. Thereafter, the nozzle body 50 is pushed upward by the second distance D4 from the engaged state shown in FIGS. 11 (A) and 11 (B) in the reverse order of assembly, as shown in FIG. 11 (A). The engagement in the rotational direction is released. Next, the nozzle body 50 is rotated 90 degrees from the second rotation angle to the first rotation angle as shown in FIG. 9A. And the nozzle body 50 is pulled out from the holder part 60 in the state of a 1st rotation angle.

  As described above, in this embodiment, the suction nozzle can be disassembled and assembled only by three operations of pushing the nozzle body 50 (upward movement), rotating the nozzle body 50, and pulling out the nozzle body 50 (downward movement). It has become.

  In the present embodiment, as described above, the axial engagement portion 54 that protrudes outward in the B direction is integrally provided in the nozzle body 50. The holder 60 is not engaged when the axial engagement portion 54 is at the first rotation angle, and is engaged in the axial direction when the axial engagement portion 54 is at the second rotation angle. The engaging piece 65 (inner upper surface 65a) is integrally provided so as to protrude inside the holder portion 60. Accordingly, the nozzle body 50 is brought into the holder portion 60 by the engagement between the axial engagement portion 54 integrally formed with the nozzle body 50 and the engagement piece 65 (inner upper surface 65a) integrally formed with the holder portion 60. Can be retained. That is, the spring member 70 can be restored in a state where the nozzle body 50 is inserted into the holder portion 60 at the first rotation angle and the nozzle body 50 is rotated so that the direction of the axial engagement portion 54 is at the second rotation angle. For example, the axial engagement portion 54 and the engagement piece 65 (inner upper surface 65a) can be engaged in the axial direction. In addition, when the nozzle body 50 is rotated from the second rotation angle to the first rotation angle also during disassembly, the nozzle body 50 can be removed by releasing the axial engagement. Thereby, since it is not necessary to provide an engagement pin or a clip member, the number of parts can be reduced correspondingly. Further, since disassembly and assembly are possible by inserting (moving) the nozzle body 50 into the holder portion 60 and rotating the nozzle body 50, it is not necessary to remove and insert (fitting) the engagement pins, and disassembly and assembly workability. Can be improved.

  In the present embodiment, the rotation direction engaging portion 57 is provided on the outer surface of the nozzle body 50. Then, in the engaged state in which the axial engagement portion 54 and the engagement piece 65 (inner upper surface 65a) are engaged in the axial direction at the second rotation angle, the rotation direction engagement portion 57 of the nozzle body 50 and the axis around the axis are engaged. An engagement piece 65 (side end surface 65 b) that engages in the rotation direction is provided on the holder portion 60. Thereby, since the nozzle body 50 and the holder part 60 can be engaged in the rotational direction in the engagement state at the second rotation angle, the nozzle body 50 rotates unintentionally and the holder part 60 The engagement can be prevented from being released.

  Moreover, in this embodiment, the engagement piece 65 in which the inner side upper surface 65a and the side end surface 65b were each formed in the front-end | tip part 61 of the holder part 60 is provided. Thereby, since both the inner upper surface 65a that engages with the axial engagement portion 54 and the side end surface 65b that engages with the rotation direction engagement portion 57 can be provided in the common engagement piece 65, the holder The structure of the part 60 can be simplified. In addition, since the engagement piece can be provided at the distal end portion 61 of the holder portion 60 where the opening 61a is formed, compared to the case where the engagement piece 65 is formed at a position on the back side in the holder portion 60, The engagement piece 65 can be easily formed.

  In the present embodiment, the engagement pieces 65 are provided so as to face each other in the E direction in pairs. A pair of rotation direction engaging portions 57 of the nozzle main body 50 are provided so as to engage with the side end surfaces 65b of the two sets of engaging pieces 65 at the respective side surfaces 53a. As a result, the engagement pieces 65 (side end faces 65b) of a set of two engage with the rotation direction engaging portions 57 of the both side surfaces 53a of the nozzle body 50 from both sides, so that the engagement state can be easily achieved. It is possible to prevent the nozzle body 50 from rotating in both directions around the axis.

  Moreover, in this embodiment, the opening 61a of the holder part 60 is made into the 1st groove part 61b which has the 1st space | interval D1 by the four engagement pieces 65, and the 2nd which has the 2nd space | interval D2 smaller than the 1st space | interval D1. It divides into the groove part 61c. And the width W3 of the B direction of the axial direction engaging part 54 of the nozzle main body 50 is below 1st space | interval D1, and larger than 2nd space | interval D2. Then, the rotational direction engaging portion 57 is formed so that the width W2 between the pair of side surfaces 53a where the rotational direction engaging portion 57 is formed is substantially equal to the second distance D2. Thus, the axial engagement portion 54 is passed from the first groove 61b at the first rotation angle, and is engaged with the inner upper surface 65a of the engagement piece 65 in the second groove 61c in the axial direction at the second rotation angle. Can do. At this time, the rotation direction engaging portion 57 can be disposed between the second groove portions 61c at the second rotation angle and can be engaged with the side end surface 65b of the engagement piece 65 in the rotation direction. As a result, the axial direction and the rotational direction can be easily achieved by only the three operations of insertion of the nozzle body 50 into the holder 60, rotation of the nozzle body 50, and return to the axial front end side by the spring member 70. The nozzle body 50 and the holder part 60 can be engaged with each other.

  In the present embodiment, the nozzle body 50 is provided so as to be movable in the axial direction by a first distance D3 until the nozzle body 42 contacts the nozzle shaft 42 in a state where the nozzle shaft 42 is inserted into the holder portion 60. Then, the rotation direction engaging portion 57 is moved from the engaged state (see FIG. 11A) in a state where the nozzle shaft 42 is not inserted, and the nozzle body 50 is held by the second distance D4 which is larger than the first distance D3. By being inserted into 60, the engagement with the engagement piece 65 (side end surface 65b) is released. Thereby, in a state where the nozzle shaft 42 is inserted into the holder portion 60, the nozzle body 50 cannot be moved by the second distance D4 for releasing the engagement in the rotation direction. For this reason, in a state where the suction nozzle 5 is mounted on the component mounting apparatus 100, the nozzle body 50 cannot be rotated from the second rotation angle to the first rotation angle, and the suction nozzle 5 cannot be disassembled. Unintentional release of the engagement between the nozzle body 50 and the holder portion 60 can be reliably prevented.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.

  Moreover, although the example which comprised so that the rotation direction engaging part 57 and the side end surface 65b of the engagement piece 65 were engaged was shown in the said embodiment, this invention is not limited to this. For example, when a convex portion extending upward is provided on the inner upper surface 65a side of the engagement piece 65 so that the lower surface 54a of the axial engagement portion 54 is engaged with the inner upper surface 65a, the axial engagement portion 54 You may make it a side end surface engage with a convex part in a rotation direction. In this case, since it is not necessary to arrange the intermediate portion 53 between the second groove portions 61c, the width W1 in the A direction of the intermediate portion 53 is reduced to the first interval D1, and the second groove portion 61c need not be provided ( The engagement piece 65 may be continuous in the E direction).

  Moreover, in the said embodiment, the axial direction engaging part 54 is formed so that it may extend linearly in A direction, and the linear 1st groove part 61b and the 2nd groove part 61c are formed in the holder part 60 side by the engagement piece 65. FIG. Although the example which formed is shown, this invention is not limited to this. The axial engagement portion 54 can pass without engaging with the engagement portion (engagement piece 65) on the holder portion side at the first rotation angle, and can be engaged with the engagement portion (engagement on the holder portion side at the second rotation angle). Any shape that engages with the piece 65) is acceptable. For this reason, it is not necessary to form the first and second groove portions on the holder portion side as well. Accordingly, the opening of the holder portion has a shape corresponding to the axial engagement portion of the nozzle body, such as a key and a keyhole, and the axial engagement portion of the nozzle body is passed through the opening at the first rotation angle. After that, the holder portion and the nozzle body may be configured so that the nozzle body cannot be removed at an angle other than the first rotation angle.

  In the above embodiment, the nozzle body 50 has the tip of the nozzle shaft 42 at the second distance D4 for releasing the engagement in the rotation direction between the rotation direction engaging portion 57 and the engagement piece 65 (side end surface 65b). Although the example set so that it may become larger than the 1st distance D3 until it contact | abuts to a part was shown, this invention is not limited to this. The second distance D4 may be smaller than the first distance D3.
