  As shown in FIGS. 6 and 7A-7C, the lead waste collection container 24 is a substantially box-shaped member having an open top surface. The lead waste collection container 24 has a main body 30 and a bottom surface 32.

  The main body 30 is a plate-like member configured by a plurality of side surfaces. The upper and lower portions of the main body 30 are open, and the lower opening is opened and closed by the bottom surface 32. 6 and 7A-7C show a state in which the bottom surface 32 is opened.

  The bottom surface 32 is a plate-like member provided so that the opening on the lower side of the main body 30 can be opened and closed. The bottom surface 32 is pivotally supported on the lower end portion of the main body 30 by a hinge 34. The hinge 34 is disposed so as to extend in the horizontal direction, and the bottom surface 32 is rotatable in the rotation direction R about the central axis A extending in the horizontal direction. The hinge 34 is biased in a direction (rotation direction R1) in which the bottom surface 32 closes the main body 30 by a biasing means such as a spring (not shown).

  A pressing surface 38 is connected to the bottom surface 32 (not shown in FIG. 6). The pressing surface 38 shown in FIGS. 7A-7C is a surface pressed against the protrusion 44 of the lead waste discharge box 16 shown in FIG. By pressing the pressing surface 38 against the protrusion 44, the bottom surface 32 that closes the main body 30 is opened.

  As shown in FIG. 7C, the side edge portion 40 forming the opening on the lower side of the main body portion 30 extends obliquely downward (see dotted line B). The bottom surface 32 that contacts the side edge portion 40 and closes the main body 30 is inclined obliquely downward in a state where the main body 30 is closed.

  Further, in the embodiment, as shown in FIG. 7A, the pressing surface 38 is provided as a surface obtained by extending the bottom surface 32 laterally. As a result, the pressing surface 38 is inclined obliquely downward like the bottom surface 32.

  The lead waste discharge box 16 shown in FIG. 6 is a box-shaped member for receiving the lead waste discharged from the lead waste recovery container 24. The lead waste discharge box 16 is a fixed object provided outside the clinch unit 15 and includes a main body 42 and a protrusion 44.

  The main body 42 is a box-shaped member having an upper surface opened. A protrusion 44 is fixed to the upper end of the main body 42.

  The protrusion 44 is a rod-shaped protrusion provided in the vicinity of the upper surface opening of the main body 42. The protrusion 44 of the present embodiment is fixed to the upper end of the main body 42 in a state extending in the horizontal direction.

  The pressing surface 38 of the above-described lead waste container 24 is pressed against the protrusion 44. By pressing the pressing surface 38 against the protrusion 44, the bottom surface 32 is opened together with the pressing surface 38, and the lead dust accumulated on the bottom surface 32 in the main body 30 can be discharged to the lead dust discharge box 16 (lead dust). Discharge step). A method for opening the bottom surface 32 of the lead waste collection container 24 by pressing the pressing surface 38 against the protrusion 44 will be described with reference to FIGS.

  FIGS. 8 to 11B are schematic views for explaining the operation of opening the bottom surface 32 of the reed waste collection container 24. 9A and 9B show the same state, FIGS. 10A and 10B show the same state, and FIGS. 11A and 11B show the same state.

  As shown in FIG. 8, first, the clinch unit 15 is moved. Specifically, the clinching unit moving mechanism 14 is driven to move the clinching unit 15 in the horizontal direction so as to approach the lead waste discharge box 16 (arrow C). Before the clinching unit 15 is moved in the horizontal direction, the height position of the pressing surface 38 of the lead waste container 24 is adjusted in advance to overlap the height position of the protrusion 44 of the lead waste discharge box 16.

  Thereafter, as shown in FIGS. 9A and 9B, the pressing surface 38 starts to contact the protrusion 44. When the movement of the clinch unit 15 further proceeds, the pressing surface 38 is pressed against the protrusion 44 in the horizontal direction. As a result, as shown in FIGS. 10A and 10B, the pressing surface 38 and the bottom surface 32 are rotated in the rotation direction R2 that is the direction in which the lead waste collection container 24 is opened. As the clinching unit 15 moves further, the pressing surface 38 is further rotated in the rotation direction R2 as shown in FIGS. 11A and 11B.

  In this manner, the pressing surface 38 is pressed against the protrusion 44, and the pressing surface 38 and the bottom surface 32 are rotated and opened in the rotation direction R2, thereby dropping the lead dust accumulated on the bottom surface 32 by gravity. be able to. The fallen lead waste is accommodated in the main body 42 of the lead waste discharge box 16 disposed below.

  According to such a method, the lead scraps collected in the lead scrap collecting container 24 can be automatically discharged by the operation of the component mounting apparatus 1 instead of manually. Specifically, the lead waste collection container 24 is provided with a pressing surface 38, and the lead scrap collection container 24 is configured to be openable and closable by pressing the pressing surface 38 against the protrusion 44. Thereby, the lead waste in the lead waste recovery container 24 can be automatically discharged, and it is not necessary to recover the lead waste recovery container 24 manually, and the lead waste can be discharged by a simple method.

  Thus, even if it is the structure where the clinch unit 15 moves by providing the lead waste collection container 24 fixed to the anvil unit 23, the lead waste collection container 24 does not restrict the movement of the clinch unit 15. Lead waste can be collected easily. Further, by providing a pressing surface 38 on the bottom surface 32 constituting the lead waste collection container 24 and opening the bottom surface 32 by pressing the pressing surface 38, the lead waste collection container 24 itself is not removed and the lead waste collection container 24 itself is removed. Can be discharged. Thereby, lead waste can be easily discharged.

  In addition, an actuator or the like for pressing the pressing surface 38 is separately provided by pressing the pressing surface 38 against the protrusion 44 which is a fixed object provided outside the clinch unit 15 so that the bottom surface 32 can be opened and closed. In addition, lead scraps can be discharged with a simple configuration.

  Further, by configuring the bottom surface 32 of the lead waste collection container 24 to be openable and closable, the lead waste accumulated on the bottom surface 32 can be more reliably discharged as compared to the case where the side surface of the lead waste collection container 24 is configured to be openable and closable. can do.

  Further, the pressing surface 38 is configured as a surface extending from the bottom surface 32 to the side, so that the pressing is performed at the time of discharging the lead waste as compared with the case where the tip side facing the central axis A of the bottom surface 32 is extended. More lead debris can be discharged without the surface 38 getting in the way.

  Further, the bottom surface 32 can be opened simply by moving the clinch unit 15 in the horizontal direction and pressing the pressing surface 38 in the horizontal direction, and the lead dust can be discharged by a simple operation.

  By implementing the above-described series of methods using the component mounting apparatus 1 of the present embodiment, the lead scrap generated by the clinching operation is automatically collected while the component mounting substrate in which the component 2 is mounted on the substrate 3 is manufactured.・ Can be discharged. An example of the overall flow relating to this is shown in FIG.

  As shown in FIG. 12, first, a substrate positioning step is performed (step S1). Specifically, as shown in FIG. 1, the substrate positioning unit 11 is used to position the substrate 3 at a predetermined position.

  Next, an insertion step is performed (step S2). Specifically, the lead 2 </ b> L of the component 2 is inserted from above into the insertion hole 3 a of the substrate 3 positioned by the substrate positioning unit 11 using the insertion head 13. In step S <b> 2, the insertion head 13 is moved in the horizontal direction and the vertical direction by the insertion head moving mechanism 12.

  Next, a clinch step is performed (step S3). Specifically, the lead 2 </ b> L protruding from the insertion hole 3 a of the substrate 3 to the lower surface side of the substrate 3 is clinched using the clinch unit 15. More specifically, using the anvil unit 23 of the clinch unit 15, the lower end portion of the lead 2L protruding to the lower surface side of the substrate 3 is cut and the remaining lead 2L is clinched. The specific method is the same as described with reference to FIGS. 4A, 4B, 5A, and 5B, and thus the description thereof is omitted. In step S <b> 3, the clinching unit 15 is moved in the horizontal direction and the vertical direction by the clinching unit moving mechanism 14.

  By mounting the component 2 on the substrate 3 in this way, a component mounting substrate is manufactured. Thereafter, a reflow step (step S4) is performed on the component mounting substrate, whereby the component 2 is soldered to the substrate 3.

  Next, a lead waste recovery step is performed (step S5). Specifically, the lead debris cut by the anvil unit 23 in step S3 is collected in the lead debris collection container 24 through the lead debris guide pipe 73 as described with reference to FIGS.

  Next, a lead waste discharging step is performed (step S6). Specifically, the pressing surface 38 provided on the bottom surface 32 constituting the lead waste collection container 24 is pressed to open the bottom surface 32 of the lead waste collection container 24. Thereby, the lead waste in the lead waste collection container 24 is discharged to the lead waste discharge box 16. The specific method is as described above with reference to FIGS.

  By performing the above steps S1 to S6, it is possible to automatically collect and discard lead scraps generated by cutting the leads 2L while manufacturing a component mounting board in which the component 2 is mounted on the board 3.

  Although the present invention has been described with reference to the above-described embodiments, the present invention is not limited to the above-described embodiments. For example, in the embodiment, the case where the protrusion 44 of the lead waste discharge box 16 that is a fixed object provided outside the clinch unit 15 is pressed against the pressing surface 38 has been described, but this is not the only case. Absent. Instead of a fixed object such as the protrusion 44, a cylinder or the like may be provided on the clinch unit 15 itself to press the pressing surface 38. Even in such a case, the lead scrap collection container 24 can be opened and closed by pressing the pressing surface 38. However, it is possible to discharge the lead dust with a simpler configuration by pressing the pressing surface 38 against the protrusion 44 which is a fixed object provided outside the clinch unit 15 as in the embodiment. The protrusion 44 is an example of a fixed object, and other arbitrary fixed objects may be employed.

  Moreover, although embodiment demonstrated the case where the bottom face 32 of the lead waste collection container 24 was openable / closable, it is not restricted to such a case. As long as the bottom surface 32 is inclined obliquely downward as in the embodiment, the side surface connected to the bottom surface 32 may be openable and closable. Even in such a case, the lead waste in the lead waste recovery container 24 can be discharged by opening the side face that can be opened and closed. However, if the bottom surface 32 of the lead waste collection container 24 can be opened and closed as in the embodiment, more lead waste can be discharged by opening the bottom surface 32 where lead waste is easily deposited.

  Moreover, although embodiment demonstrated the case where the pressing surface 38 was provided as a surface which extended the bottom face 32 of the lead waste collection container 24 to the side, it is not restricted to such a case. The pressing surface 38 may be provided as an extended surface of the tip side at a position facing the central axis A, not the side of the bottom surface 32. Even in such a case, the lead waste collection container 24 can be opened and closed by pressing the pressing surface 38. However, when the pressing surface 38 is provided with the bottom surface 32 extended laterally, the pressing surface 38 becomes an obstacle when discharging lead waste, compared to the case where the tip end side of the bottom surface 32 is extended. Therefore, more lead waste can be discharged.

  In the embodiment, the case where the lead waste discharge box 16 is a box-shaped member has been described. However, the present invention is not limited to such a case, and a dust chute connected to the outside of the component mounting apparatus 1 may be used.

  Although the present disclosure has been fully described in connection with preferred embodiments with reference to the accompanying drawings, various variations and modifications will be apparent to those skilled in the art. Such changes and modifications are to be understood as included within the scope of the present disclosure as set forth in the appended claims. In addition, combinations of elements and changes in the order in each embodiment can be realized without departing from the scope and spirit of the present disclosure.

  It is to be noted that, by appropriately combining any of the various embodiments and modifications, the effects possessed by them can be produced.

  The present invention is applicable to any component mounting apparatus and method for manufacturing a component mounting board using the same.
