  Next, with reference to FIGS. 4-8, the detailed structure of the suction nozzle 20 of this Embodiment is demonstrated. FIG. 4 is a three-side view of the suction nozzle 20. 4 (a) and 4 (b) show the front and side surfaces of the suction nozzle 20, respectively, and FIG. 4 (c) shows the top surface of the suction nozzle 20 shown in FIG. 4 (a). 5, FIG. 6, and FIG. 7 described below show the AA cross section, the BB cross section, and the CC cross section in FIG. 4, respectively. FIG. 8 is a partially enlarged view of the vicinity of a long hole and a groove formed in the suction nozzle 20 described below.

  In FIG. 4A and FIG. 6, long holes 29 that are long in the direction in which the nozzle body 21 slides (vertical direction) are formed on the two opposing side surfaces 22 b of the nozzle body holding part 22. The long hole 29 penetrates from the outer periphery of the nozzle body holding part 22 to the fitting hole 25. A cylindrical pin 30 protrudes in the radial direction of the fitting hole 25 (left and right direction perpendicular to the vertical direction) at the base end portion 26 of the nozzle body 21 inserted into the fitting hole 25 of the nozzle body holding portion 22. It is installed.

  In FIG. 6, the left and right end portions 30 a and 30 b of the pin 30 protruding from the nozzle main body 21 protrude into long holes 29 formed in the nozzle main body holding portion 22, respectively. That is, the pin 30 is attached to the nozzle body 21 through the space between the opposed long holes 29. As the nozzle body 21 slides up and down, the pin 30 moves up and down in the long hole 29 (arrow a in FIG. 8B). The nozzle body 21 that moves up and down is restricted from rotating about the vertical direction by the pin 30 and the long hole 29.

  Thus, the pin 30 is provided in the base end portion 26 so as to protrude in the radial direction of the fitting hole 25, and the fitting hole is formed on the side surface 22 b of the nozzle body holding portion 22 along the direction in which the nozzle body 21 slides. A long hole 29 penetrating up to 25 is formed, and the pin 30 moves in the long hole 29 as the nozzle body 21 slides in the fitting hole 25.

  5 and 6, the nozzle body 21 is urged downward with respect to the nozzle body holding portion 22 by a coil spring 28, and the pin 30 attached to the nozzle body 21 is similarly urged downward. . In FIG. 8A, a contact surface 29 a with which the pin 30 biased downward is contacted is formed in the lower portion of the long hole 29. The contact surface 29a includes two inclined surfaces 29b formed symmetrically at the center of the long hole 29 in the circumferential direction of the nozzle body holding portion 22 and a lower end 29c sandwiched between the two inclined surfaces 29b.

  In FIG. 8B, the nozzle body 21 is restricted from moving downward when the outer periphery of the cylindrical pin 30 abuts against a part D of the two inclined surfaces 29b of the abutment surface 29a. Further, the nozzle body 21 is restricted from moving upward when the outer periphery of the pin 30 comes into contact with the upper end surface 29 d formed at the upper portion of the long hole 29. Hereinafter, the position of the nozzle body 21 where the pin 30 biased downward is in contact with the two inclined surfaces 29b of the contact surface 29a of the long hole 29 is referred to as a “downward restriction position”.

  In FIG. 5, the length L1 above the long hole 29 including the long hole 29 of the base end portion 26 is longer than the length L2 of the long hole 29 in the direction in which the nozzle body 21 slides (vertical direction). Therefore, even when the nozzle main body 21 is moved to the lower restriction position, the long hole 29 is blocked by the outer peripheral surface of the base end portion 26 of the nozzle main body 21. Thereby, the vacuum of the suction path (the fitting hole 25, the upper suction hole 26a, and the lower suction hole 27b) inside the suction nozzle 20 in which the nozzle body 21 slides up and down is maintained.

  6 and 8A, a groove portion 31 is formed on the side surface 22b of the nozzle body holding portion 22 in which the long hole 29 is formed, downward from the lower end 29c of the contact surface 29a. In FIG. 6, the bottom surface 31 a of the 31 groove portion is inclined outward from the nozzle main body holding portion 22 toward the lower side. In FIG. 8A, the groove portion 31 is located below the center of the long hole 29 in the circumferential direction of the nozzle body holding portion 22, and the width W1 of the groove portion 31 in the circumferential direction of the nozzle body holding portion 22 is It is smaller than the diameter W2.

  4A and 6, in the nozzle main body holding portion 22, the flange portion 23 is formed below the groove portion 31. 6 and 7, the flange portion 23 includes a flange portion 23a formed extending from the outer periphery of the nozzle body holding portion 22, and a wall portion 23b extending upward from the outer edge of the flange portion 23a. ing. The flange portion 23a has a substantially circular disk shape when viewed from above, and has two edges 23c obtained by cutting off two opposing sides. The wall portion 23b is formed so as to surround the flange portion 23a along the outer edge of the flange portion 23a.

  A mark 32 for recognizing information identifying the suction nozzle 20 such as a barcode, a two-dimensional code, and RFID is attached to the upper surface of the flange portion 23a. Thus, a substantially circular flange portion 23 a extending in the radial direction of the fitting hole 25 is formed below the groove portion 31 in the nozzle body holding portion 22. At least one edge 23c is formed on the outer edge of the flange portion 23a, and an upward wall portion 23b is formed around the outer edge of the flange portion 23a.

  Next, the behavior of the suction nozzle 20 in the component mounting operation in which the component P is held by the suction nozzle 20 having the above-described configuration and mounted on the substrate 3 will be described with reference to FIGS. In the component mounting operation, first, as shown in FIG. 9A, the suction nozzle 20 that holds the component P by vacuum suction on the component suction surface 27 a at the lower end portion of the nozzle body 21 by operating the negative pressure generating source 17. And positioned above the component mounting point of the substrate 3. At this time, the nozzle main body 21 is urged downward by the coil spring 28 and is in the lower restriction position where the pin 30 abuts against the two inclined surfaces 29 b of the long hole 29.

  Next, as shown in FIG. 9 (b), the suction mechanism 20 of the nozzle holding part 8 is operated from the state shown in FIG. 9 (a) to lower the suction nozzle 20 (arrow b), and the nozzle body 21 is in the lower restriction position. In this state, the component P held by the nozzle body 21 is landed on the component mounting point of the substrate 3. Next, as shown in FIG. 9C, the suction nozzle 20 is further lowered from the state shown in FIG. 9B (arrow c), and the nozzle main body 21 is moved from the lower restriction position to the nozzle main body holding portion 22. Push in relative to the push allowance ΔH. In this state, the coil spring 28 is compressed by the pushing allowance ΔH, and a pressing load due to the coil spring 28 being compressed by ΔH acts on the component P.

  FIG. 10 shows the appearance of the suction nozzle 20 in the state of FIG. 9C as viewed from the front (the long hole 29 side). In this way, in the component mounting operation, the lifting mechanism of the nozzle unit 6 is controlled based on the position of the component suction surface 27a where the nozzle body 21 is in the downward restriction position, and the component P held by the suction nozzle 20 is mounted on the substrate 3 as a component. The substrate is landed on the point, and is further pushed by the pushing allowance ΔH to be applied to the substrate 3 by applying a predetermined pressing load.

  Next, with reference to FIG. 11, functions of the two inclined surfaces 29 b of the long hole 29, the groove portion 31, and the flange portion 23 formed in the suction nozzle 20 will be described.

In the suction nozzle 20, foreign matter 33 such as dust may fall into the long hole 29 while the component mounting operation is continuously performed. When the foreign material 33 adheres to the contact surface 29a of the long hole 29 and is sandwiched between the pin 30 and the contact surface 29a, the lower restriction position of the nozzle body 21 changes from the set position, so that the component P is normal to the substrate 3. Can no longer be installed.

  In the suction nozzle 20 of the present embodiment, the foreign material 33 that has dropped onto the contact surface 29a of the long hole 29 falls into the groove 31 through the slope 29b (arrow d). Furthermore, the foreign material 33 is discharged to the flange portion 23a of the flange portion 23 along the inclination of the bottom surface 31a of the groove portion 31 (arrow e). Thereby, the positioning accuracy of the lower restriction position of the suction nozzle 20 is maintained, and the interval of maintenance work such as removal of the foreign matter 33 attached to the suction nozzle 20 by the operator can be lengthened. Further, the foreign matter 33 discharged to the flange portion 23a is prevented from falling from the flange portion 23 and diffusing out of the suction nozzle 20 by the wall portion 23b surrounding the flange portion 23a.

  As described above, the suction nozzle 20 of the present embodiment sucks the nozzle body holding portion 22 having the fitting hole 25, the base end portion 26 and the component P that are slidably fitted in the fitting hole 25. And a nozzle body 21 including a lower end 27 on which a component suction surface 27a is formed. A pin 30 is provided on the proximal end portion 26 so as to protrude in the radial direction of the fitting hole 25. A long hole 29 is formed in the side surface 22b of the nozzle main body holding portion 22 so as to penetrate the fitting body 25 along the sliding direction of the nozzle main body 21, and as the nozzle main body 21 slides, the pin 30 becomes a long hole. Move in 29.

  A contact surface 29a with which the pin 30 contacts is formed at the lower end of the long hole 29, and a groove portion 31 is formed on the side surface 22b of the nozzle body holding portion 22 from the lower end of the contact surface 29a downward. . The bottom surface 31a of the groove portion 31 is inclined outwardly from the nozzle body holding portion 22 toward the lower side. As a result, the foreign matter 33 that has fallen on the contact surface 29a is naturally removed from the contact surface 29a, so that the number of periodic maintenance can be reduced.

  The suction nozzle and the component mounting apparatus of the present invention have an effect that the number of periodic maintenance can be reduced, and are useful in the field of mounting components on a substrate.
