The bottom surface 32 of the hinge 34 is urged in the direction of closing the main body 30 (rotational direction R1) by an urging 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 that is 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 lower opening of the main body portion 30 extends obliquely downward (see dotted line B). The bottom surface 32, which abuts on the side edge portion 40 and closes the main body portion 30, is inclined obliquely downward with the main body portion 30 closed.

Further, in the embodiment, as shown in FIG. 7A, the pressing surface 38 is provided as a surface extending the bottom surface 32 sideways. As a result, the pressing surface 38 is arranged so as to be inclined diagonally downward as in the bottom surface 32.

By pressing the pressing surface 38 against the protrusion 44, the bottom surface 32 can be 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 waste discharge box 16 (lead waste). Discharge step). A method of pressing the pressing surface 38 against the protrusion 44 to open the bottom surface 32 of the lead waste collecting container 24 will be described with reference to FIGS. 8 to 11B.

8 to 11B are schematic views for explaining an operation of opening the bottom surface 32 of the lead waste collecting 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 clinch unit moving mechanism 14 is driven to move the clinch unit 15 in the horizontal direction so as to approach the lead waste discharge box 16 (arrow C). Before moving the clinch unit 15 in the horizontal direction, the height position of the pressing surface 38 of the lead waste storage container 24 is adjusted so as to overlap the height position of the protrusion 44 of the lead waste discharge box 16.

After that, as shown in FIGS. 9A and 9B, the pressing surface 38 starts to come into contact with the protrusion 44. As the clinch unit 15 moves further, 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, which is the direction in which the lead waste collecting container 24 is opened. As the clinch unit 15 moves further, the pressing surface 38 is further rotated in the rotation direction R2, as shown in FIGS. 11A and 11B.

By pressing the pressing surface 38 against the protrusion 44 in this way and rotating the pressing surface 38 and the bottom surface 32 in the rotation direction R2 to open the pressing surface 38, the lead debris accumulated on the bottom surface 32 is dropped downward by gravity. be able to. The dropped lead waste is housed in the main body 42 of the lead waste discharge box 16 arranged below.

According to such a method, the lead waste collected in the lead waste collecting container 24 can be automatically discharged by the operation of the component mounting device 1 instead of manually. Specifically, the reed waste collection container 24 is provided with a pressing surface 38, and the reed waste collecting container 24 can be opened and closed by pressing the pressing surface 38 against the protrusion 44. As a result, the lead waste in the lead waste collection container 24 can be automatically discharged, and the lead waste can be discharged by a simple method without having to manually collect the lead waste collection container 24.

By providing the lead waste collecting container 24 fixed to the anvil unit 23 in this way, even if the clinch unit 15 is configured to move, the lead waste collecting container 24 does not limit the movement of the clinch unit 15. Reed waste can be easily collected. Further, by providing a pressing surface 38 on the bottom surface 32 constituting the lead waste collecting container 24 and pressing the pressing surface 38 to open the bottom surface 32, the lead waste collecting container 24 itself is not removed and the lead waste is opened. Can be discharged. As a result, lead waste can be easily discharged.

Further, by pressing the pressing surface 38 against the protrusion 44 which is a fixed object provided outside the clinch unit 15 to open and close the bottom surface 32, an actuator or the like for pressing the pressing surface 38 is separately provided. It is possible to discharge lead waste 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 discharged more reliably as compared with the case where the side surface of the lead waste collection container 24 can be opened and closed. can do.

Further, by forming the pressing surface 38 with the bottom surface 32 extending laterally, the pressing surface 38 is pressed when the lead waste is discharged, as compared with the case where the tip side of the bottom surface 32 facing the central axis A is extended. More lead debris can be ejected without the surface 38 getting in the way.

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

By carrying out the above series of methods using the component mounting device 1 of the present embodiment, the lead waste generated by the clinch operation is automatically collected while manufacturing the component mounting board on which the component 2 is mounted on the board 3.・ Can be discharged. An example of the overall flow in this regard 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 2L of the component 2 is inserted from above into the insertion hole 3a of the substrate 3 positioned by the substrate positioning unit 11 using the insertion head 13. In step S2, 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 clinch unit 15 is used to clinch the lead 2L protruding from the insertion hole 3a of the substrate 3 toward the lower surface side of the substrate 3. More specifically, the anvil unit 23 of the clinching unit 15 is used to cut the lower end portion of the lead 2L protruding toward the lower surface side of the substrate 3 and clinching the remaining lead 2L. Since the specific method is as described with reference to FIGS. 4A, 4B, 5A, and 5B, the description thereof will be omitted. In step S3, the clinch unit 15 is moved horizontally and vertically by the clinch unit moving mechanism 14.

By mounting the component 2 on the substrate 3 in this way, a component mounting substrate is manufactured. After that, a reflow step (step S4) is performed on the component mounting board to solder the component 2 to the board 3.

Next, a lead waste collecting step is carried out (step S5). Specifically, the lead waste cut by the anvil unit 23 in step S3 is collected in the lead waste collection container 24 via the lead waste guide pipe 73 as described with reference to FIGS. 2 and 3.

Next, a lead waste discharging step is carried out (step S6). Specifically, the bottom surface 32 of the lead waste collection container 24 is opened by pressing the pressing surface 38 provided on the bottom surface 32 constituting the lead waste collection container 24. As a result, the lead waste in the lead waste collection container 24 is discharged to the lead waste discharge box 16. Since the specific method is as described above with reference to FIGS. 8-11B, the description thereof will be omitted.

By carrying out the above steps S1-S6, it is possible to automatically collect and dispose of the lead waste generated by cutting the lead 2L while manufacturing the component mounting board in which the component 2 is mounted on the substrate 3.

Although the present invention has been described above 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 which is a fixed object provided outside the clinch unit 15 is pressed against the pressing surface 38 has been described, but only in such a case. do not have. 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 reed waste collecting container 24 can be opened and closed by pressing the pressing surface 38. However, if the pressing surface 38 is pressed against the protrusion 44, which is a fixed object provided on the outside of the clinch unit 15 as in the embodiment, the lead waste can be discharged with a simpler configuration. The protrusion 44 is an example of a fixed object, and any other fixed object may be adopted.

Further, in the embodiment, the case where the bottom surface 32 of the lead waste collecting container 24 can be opened and closed has been described, but the case is not limited to such a case. If the bottom surface 32 is inclined diagonally downward as in the embodiment, the side surface connected to the bottom surface 32 may be opened and closed. Even in such a case, the lead waste in the lead waste collection container 24 can be discharged by opening the side surface 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, the bottom surface 32 on which lead waste is likely to be accumulated can be opened and more lead waste can be discharged.

Further, in the embodiment, the case where the pressing surface 38 is provided as the surface extending from the bottom surface 32 of the lead waste collecting container 24 to the side has been described, but the case is not limited to such a case. The pressing surface 38 may be provided as an extended surface on the tip end side located at a position facing the central axis A instead of the side surface of the bottom surface 32. Even in such a case, the lead waste collecting container 24 can be opened and closed by pressing the pressing surface 38. However, if the pressing surface 38 is provided as a surface extending the bottom surface 32 to the side, the pressing surface 38 becomes an obstacle when discharging the lead waste, as compared with the case where the tip side of the bottom surface 32 is extended. It is possible to discharge more lead waste.

Further, in the embodiment, the case where the lead waste discharge box 16 is a box-shaped member has been described, but the case is not limited to such a case, and a dust chute connected to the outside of the component mounting device 1 may be used.
