Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a component mounting machine for components having lead terminals.
[0002]
[Prior art]
A conventional component mounter will be described below. In a conventional component mounter, a component having a component main body on one end side and a transport band on the other end side of a plurality of lead terminals is held by the holding unit while the middle part of the lead terminal is held by the holding unit. The lead terminal on the transport band side is cut by the cutting means rather than the portion.
[0003]
That is, the component main body has a plurality of lead terminals, and the lead terminals are fixed to a belt-like transport belt. The parts are transported one by one in the belt-like transport belt, and at the transport end point, the belt-like transport belt. In this case, the individual transport belt is cut off from the transport belt, and then the transport belt is cut off from the lead terminal.
[0004]
[Problems to be solved by the invention]
As described above, the carrier band is cut off from the lead terminal of the component main body by the cutting means, but the cutting means wears with this cutting operation, and eventually the carrier band cannot be reliably separated from the lead terminal. there were. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reliably separate a transport band from lead terminals.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the present invention is provided with a pressing means for pressing the individual transport band in the longitudinal direction of the strip-shaped transport band after the cutting operation of the lead terminal by the cutting means. In other words, after the cutting operation of the lead terminal by the cutting means, if the individual conveying band is pressed by the pressing means in the longitudinal direction of the band-shaped conveying band, the conveying band is surely separated from the lead terminal in an incompletely cut state. It will be able to do things. Further, since the pressing means has a concave groove in the longitudinal direction of the lead wire, it is possible to surely press the transport band in the longitudinal direction by the concave groove of the pressing means. That is, since the conveying body is encased in the concave groove and pressed in the longitudinal direction, the conveying band can be reliably separated from the lead wire. Furthermore, since the pressing means is constituted by a lever having a concave groove on one end side and a fulcrum on the other end side, the concave groove can be rotated largely around the fulcrum on the other end side of the lever. Thus, the transport band can be reliably separated from the lead terminal.
[0009]
According then to the invention described in claim 2 of the present invention, the fulcrum of the pressing means is a component mounting machine according to claim 1 provided on the cutting side of the groove, it presses the pressing means in the conveying zone In this case, a force is applied so that the pressing means pushes the transport band in a substantially parallel direction, which facilitates reliable separation of the transport band from the lead terminal.
[0010]
According then to the invention described in claim 3 of the present invention, the cutting means and the pressing means is a component mounting machine according to claim 1 or 2 and configured to be driven by one cam, and cutting means Since the pressing means is driven by a single cam, the pressing means can be pressed at the end of the cutting operation, that is, the timing of both is not lost, thereby reliably separating the transport band from the lead terminal. It will be able to do.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
[0012]
In FIG. 1, reference numeral 1 denotes a component main body, which is fixed to one end side of two lead terminals 2. On the other end side of the lead terminal 2, as described above, the transport band 3 that is cut off from the strip-shaped transport band into individual pieces is fixed. That is, in the one shown in FIG. 1, what is transported by a long belt-like transport belt is separated into the transport belt 3 which is an individual piece shown in FIG. It is what is shown in. FIG. 1 shows a state where the transport band 3 is separated from the lead terminal 2. In this case, the middle portion of the lead terminal 2 is held by the left and right holding means 4, and the conveyance band 3 side is cut by the left and right cutting blades 6 relative to the holding portion.
[0013]
Specifically, the left and right cutting blades 6 are pressed strongly below the holding means 4, thereby separating the transport band 3 from the lead terminals 2. In this case, first, the cutting blade 6 is strongly pressed against the lead terminal 2, and in this pressed state, the pressing means 7 presses the transport band 3 to the left side in FIG.
[0014]
That is, even when the cutting blade 6 cannot reliably separate the transport band 3 from the lead terminal 2, the cutting means 6 is pressed to the left side of FIG. The conveyance band 3 is separated from the lead terminal 2 formed as described above. In this case, as shown in FIG. 1, the pressing means presses the transport belt 3 in the longitudinal direction, that is, the left side in FIG. 1, but the pressing means 7 is recessed in the longitudinal direction of the lead terminal 2. A groove 8 is provided.
[0015]
Therefore, the transport band 3 is pressed to the left side in FIG. 1 in a state where the transport band 3 is fitted in the concave groove 8. In order to perform such an operation, the pressing means has a concave groove 8 on one end side and a lever 10 pivotally supported by a fulcrum 9 on the other end side. FIG. 2 shows the state of the fulcrum 9 and the holding means 7. As shown in FIG. 2, the fulcrum 9 is closer to the transport belt 3 when the pressing means 7 is not rotating.
[0016]
This is a state in which the fulcrum is located at the intermediate portion between the transport belt 3 and the pressing means 7. By providing the fulcrum 9 at such a position, when the pressing means 7 is pressed toward the conveyance band, a force is applied so that the pressing means 7 pushes the conveyance band 3 in a substantially parallel direction, thereby conveying from the lead terminal 2. This makes it easier to reliably separate the band 3.
[0017]
For comparison, when the fulcrum 9 is located on the right side of the holding means 7 as shown in FIG. 3, the pressing means 7 is transported downward from the state shown in FIG. It will be in the state where force is applied to belt 3. In that case, a sufficient force will be applied to the right terminal of the lead terminals 2, but the left terminal may not be applied to the left one, and the left lead terminal 2 may remain. On the other hand, if the fulcrum 9 is provided on the left side of the pressing means 7 as shown in FIG. 2, the holding means 7 moves in the parallel direction, so that it becomes easier to separate the transport band 3 from the lead terminal 2. Is.
[0018]
In this manner, the cutting blade 6 and the pressing means 7 always operate in such a manner that the cutting blade 6 firstly performs the cutting operation of the lead terminal 2 and then remains in the pressing means 7 when the conveying band 3 is moved. Will be pressed. In order to perform such a coordinated operation, the cutting blade 6 and the pressing means 7 are driven by a single cam 11 as shown in FIG. In FIG. 4, although one cam 11 is actually provided with two cam plates 12, 13, a cam follower 14 and a lever 15 are rotated on one cam plate 12 to provide a cutting blade 6. The cam plate 13 is configured to be driven, and the cam follower 16 and the lever 17 are rotated to connect the pressing means 7 to the cam plate 13.
[0019]
【The invention's effect】
As described above, according to the present invention, the holding of the component main body on one end side of the plurality of lead terminals and the part having the transport band on the other end side is held by the holding means in the state where the middle portion of the lead terminal is held by the holding means. also cut with the cutting means of lead terminals of the conveyor belt side than parts, after the cutting operation of the lead terminal by the cutting means, if still have conveyor belt to the lead terminal is transported by pressing means belt-like conveyor belt Since it is configured to press in the longitudinal direction of the band, the conveyance band can be reliably separated from the lead terminal.
