In particular, there is a need for a lead forming process that allows the lead portion to be easily inserted and held when mounting a radial component on a printed board.

(c) Prior art and problems Figure 1 is a diagram for explaining printed board mounting, in which figure a is a three-dimensional view showing a radial component, and figure b is a side sectional view and main points showing the mounted state. FIG. In the figure, 1 is a component, 2 is a lead portion, 3 is a printed board, 4 is an insertion hole, and 5 is a pair of tapered pliers.

Conventionally, a large number of LSIs, radial components such as capacitors, etc. have been mounted on a printed board in a printed board unit of a control section used in a printer device, for example. As shown in Fig. 1a, this radial component has a bypass capacitor having a lead portion 2 formed below the component 1, and the lower tip of the lead portion 2 of this bypass capacitor 1 has a square shape. There is. As a mounting method, the leads 2 of the bypass capacitor of the radial component 1 are inserted into the many insertion holes 4 provided in the printed board 3 as shown in FIG. Bend the tip of the lead part 2 with tapered pliers 5, etc. and insert it into the insertion hole 4 at the insertion position 1A.
is held in Therefore, processing of the ultra-thin lead portion 2 requires a lot of effort, has poor workability, and has disadvantages such as manual mounting, which hinders automatic mounting.

(d) Purpose of the Invention In view of the above-mentioned conventional drawbacks, an object of the present invention is to provide a transfer device that has a simple configuration and can easily and automatically mold the lead portion of a bypass capacitor. be.

(e) Structure of the Invention According to the present invention, the purpose is to provide a transfer device that automatically performs lead forming processing on a component having a lead portion, and a first transfer device that processes the component transferred to each process. in a step, means for press-forming the lower end of the lead; in a second step, means for aligning the opening pitch of the tip of the pressed lower end of the lead and cutting the lower tip;
This is achieved by providing a transfer device characterized in that it has a structure that includes means for forming a curved forming on the cut lead portion in the step.

(f) Embodiment of the Invention An embodiment of the present invention will be described in detail below with reference to the drawings.

Figure 2 is a diagram for explaining the transfer device according to the present invention; Figure a is a top view showing the structure, Figure b is a process diagram showing the forming process, and Figure 3 is a diagram showing the forming shape. FIG. 3A is a front view, FIG. 1B is a side view, FIG. 1C is a side view of a main part, and FIG.

In this figure, the same parts used in FIG. 1 are given the same numbers. Further, 6 is a fixed base, 7 is a cylinder, and a presser 8 is provided so as to be swingable with respect to the fixed base 6. Reference numeral 9 denotes a receiver, which is attached to the fixed base 6. Reference numeral 10 indicates a spalling type, 11 a cutting type, 12 a forming type, and 13 a forming shape.

In the transfer device of the present invention, as shown in FIG. 2, a presser 8 attached to a cylinder 7 is provided on a fixed base 6 so as to be able to swing from side to side and back and forth. The structure is such that a receiver 9 for transferring and molding between processes D and E is provided on a fixed table 6.

The receiver 9 of the device configured in this way has a second
As shown in FIG. b, for parts setting by parts feeding in the first step A and coining forming in the second step B, a hammer mold 10 is provided as a means for determining the length of the lead part 2 and press-forming the tip. Further, in the third step C, a cutting die 11 is provided as a means for determining the pitch P of the lead portion 2 and cutting the tip, and further, in the fourth step D.
For forming forming, a forming mold 12 is provided as a means for correcting the leads of the lead portion 2 and shaping the staggered forming 13.

In the operation of such an apparatus, first, a part 1 is automatically fed from a parts feeder (not shown) and set in a first process A. Next, the cylinder 7 is driven by a drive source (not shown), and the presser 8 connected to the cylinder 7 is swung downward in the direction of the arrow to clamp the part 1, and then the cylinder 7 moves in the right direction to move the part 1 to the second process. When the lead portion 2 is transferred to the point B, the blade mold 10 is driven by a drive source (not shown), and the length of the lead portion 2 is determined and the tip coining is performed by pressing the lead portion 2 in the direction of the arrow.

At this time, the holding tool 8 is released from its grip by the drive of the cylinder 7, is swung for one step, and returns to its original position, and the next part 1 is set in the first step A. This inter-process swinging of the presser 8 is performed in the same manner in the third process C and the fourth process D. Then, part 1 of the second process B completed.
The cylinder 7 is driven and the presser 8 swings again to clamp it and transfer it to the third process C. Then, the cutting die 11 is driven by a drive source (not shown), and the pitch P of the lead portion 2 is determined and the tip is formed by movement in the direction of the arrow. Then, in a fourth step D, the part 1 is transferred while being clamped, and the forming mold 12 is driven by a drive source (not shown), and the lead part 2 is moved in the direction of the arrow.
The lead is corrected and the shape of the staggered forming 13 is formed and transferred to the processed E. At this time, the transfer of each step of the component 1 and the lead forming process are automatically performed by continuous operation.

As shown in FIG. 3, the shape of this lead portion 2 is for correcting the pitch P (FIG. 3a), for positioning (FIG. 3b), and as a form 13 for preventing slippage. As shown in FIG. 3d, the component 1 is simply mounted on the printed board 3.

In the present invention, the two leads 2 are staggered, but they may be in the same direction.

Therefore, since the lead portion 2 of the radial component 1 is processed by this automatic machine, the lead pitch P
Since the lead part 2 is corrected and the tip is formed, it is easy to insert into the insertion hole 4 of the printed board 3, and
Printed board 3 due to lead forming 13 shape
I can't get out of it. Furthermore, since the dimensional accuracy is high, automatic insertion is easily possible, which improves work efficiency and reduces costs.

(g) Effects of the Invention As explained above in detail, the transfer device of the present invention has a simple configuration, good operability, and a simple structure of the forming process to easily automate the forming process of the lead part. This has a great effect in that it can improve workability.
