Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cutting a hoop-shaped part in which a supply path and a transfer path used for surface mounting are not on the same line.

[0002]

2. Description of the Related Art Conventionally, cutting and molding of wound and molded hoop-shaped parts are carried out by using a cutting and molding machine in which the feeding path and the conveying path of the hoop-shaped parts are on the same axis. Is common. This is because a semi-finished product obtained by installing a core or the like on a terminal portion of a lead frame, winding the core, and molding the product is continuously arranged in a straight line so as to be orthogonal to the longitudinal direction. Because it is.

[0003]

For example, in the winding step, when the hoop having a linear shape in the horizontal direction travels in a straight line, the winding start position is determined by the predetermined length of the winding frame of the component. Since the distance between the winding end position is different from that of the winding end position, it is necessary to perform alignment again after completing one winding.
For this reason, there is a drawback that the takt time becomes very long and the productivity is lowered.

In order to overcome this drawback, the hoop is formed at a predetermined angle with respect to the vertical direction, so that Japanese Patent Application No. 04-293533 and Japanese Patent Application No. 05-304.
As proposed in 151, since the end position of the winding and the start position of the next winding can be made the same, the takt time can be shortened significantly. The angle of the semi-finished product parts attached to the hoop is determined by the processing method (winding in this case) in the previous step and the size and shape of the parts.

However, as described above, in the cutting / forming machine, when the semi-finished product parts attached to the hoop are attached in a shape with a certain angle, the supply path and the transfer path are on the same axis. It could not be placed on top and it was very difficult to cut and form hoop-shaped parts.

According to the present invention, the productivity can be improved by shortening the tact time even if the hoop-shaped component is attached to the hoop at a certain angle, that is, defects are automatically selected, easily and in a short time. An object of the present invention is to provide a device for cutting a hoop-shaped part to be cut / formed.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a feeding path and a conveying path of a hoop-shaped component in which the component has a predetermined angle with respect to the hoop are arranged on different axes at a certain predetermined angle, and the cutting step is performed. A first cutting part for separating and cutting from the hoop-shaped part is arranged, and a second cutting part for cutting the individual parts cut by the first cutting part into a predetermined shape is arranged. It is a device for cutting a hoop-shaped part, characterized in that the second cutting portion is synchronized and interlocked.

[0008]

According to the present invention, since the feed path and the transport path of the hoop-shaped parts are arranged at a predetermined angle, it is possible to easily cut even if the parts attached to the hoop have an angle. Therefore, it is possible to shorten the time of the cutting process and improve the productivity.

Furthermore, by dividing the cutting process into two first and second cutting portions, smooth movement from the supply path to the conveyance path can be achieved while preventing chipping and defective cutting. Further, when a defective product such as a defective mold or a missing terminal comes in, it is possible to sort between the first cutting portion and the second cutting portion.

Since the cut parts are simultaneously cut in the first cutting part and the second cutting part, for example, when the first part is cut by the second cutting part, the N-th part is the first cutting part. Will have been disconnected in. When the Nth part is conveyed to the second cutting part, at the same time, the N + 1th part is conveyed to the first cutting part, and when the Nth part is cut at the second cutting part, the N + 1th part is It is cut at 1 cutting part. This means that if you look at one part,
The cutting of the cutting portion and the cutting of the second cutting portion are performed separately, but in terms of takt time, it is equivalent to cutting the first cutting portion and the second cutting portion at the same time with one component, It is very efficient and shortens the cutting process.

(B) is a top view which shows the cutting | disconnection state of components when a hoop-shaped component is poured into the cutting apparatus of this invention. FIG. 1C is an explanatory view showing the structure of the transport pin of the cutting device of the present invention. FIG. 2 is a plan view showing a hoop-shaped component cut by the cutting device of the present invention and a cut state of the component. Figure 2

(C) is a plan view showing a cut state and a shape of a component cut by the second cutting portion.

As shown in FIG. 1 (a), the hoop-shaped component cutting device of the present invention has a planar feed path 1 and a transport path 2.
And a first cutting part 3 and a second cutting part 4 having a pair of facing cutting parts.

As shown in FIG. 2A, the hoop-shaped component 5 is, for example, an inductor element or the like, in which the core is arranged at the terminal portion of the lead frame 12, the winding 20 is formed, and the molded component 11 is formed. It has a predetermined angle and is molded.

Further, as shown in FIG. 1 (b), the hoop-shaped component 5 has a predetermined angle with respect to the conveying path 2 provided on the plane of the device for cutting the hoop-shaped component of the present invention. It moves on the arranged supply path 1 toward the conveyance path.

The uncut parts 14 which have not been cut yet on the lead frame 12 are separated from the hoop-shaped lead frame by the first cutting part 3 provided in the vicinity of the terminal end of the supply path 1 as shown in FIG. 2 (b). It is cut and separated in the state of the first cut component 6 leaving 13a and the cut portion 13b.

As shown in FIG. 1 (c), the device for cutting the hoop-shaped component has a transport pin mounting moving portion 9 to which the transport pin 8 is mounted. The transport pin attachment moving unit 9 has a pair of transport pins 8a and 8b, and moves to a vertical arrow 16.
And it moves to the arrow 17 in the horizontal direction.

The rear transport pin 8a moves the first cutting component 6 cut at the first cutting portion to the position A. The front transport pin 8b moves the first cut component, which has been moved to the position A by the rear transport pin 8a, to the position B. Further, the transport pin mounting moving unit 9 serves to transport two parts at the same time. Therefore, the transport pin attaching / moving unit 9 repeats this operation, and the transport pin 8 sequentially cuts and sends the components. If a defective product such as a defective mold flows in here, the center of gravity shifts, so that the product is automatically dropped from the transfer path before being transferred by the transfer pin 8 and is sorted.

The component 6 moved to the position A is shown in FIG.
2C, the second cutting portions 4a and 4b attached to both sides of the transport path 2 as shown in FIG.
a, the cutting portion 13b is cut.

The cut part becomes a second cut part 7 having a predetermined terminal 18 as shown in FIG. 2 (c).

[0020]

As described above, according to the present invention,
Since the feed path and the transport path for the hoop-shaped parts are arranged at a predetermined angle, it is possible to continuously cut even if the hoop-shaped lead frame itself is angled, and the tact in the previous process It is possible to reduce time and improve productivity.
In addition, it is possible to easily cut and form the hoop-like parts in a short time while automatically selecting defects.
