Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an apparatus for manufacturing printed circuit boards equipped with pin terminals for electrical connectors.

Background technology Printed circuit boards used for wiring electrical components,
Alternatively, there are pin terminals of so-called multi-polar housing connectors that can freely connect and separate the printed circuit board and other electrical components, as shown in FIGS. 6 and 7. In the pin terminals shown in FIGS. 6 and 7, a predetermined number of pin terminals 5 are inserted into a connector pin body 21 to form a single component pin body assembly 22, and then A pin body assembly 22 is fixed at a predetermined position of 7 with solder. In the pin terminal 5 configured in this way, it is necessary to once manufacture the pin body assembly 22 using the pin body 21, and further,
The manufactured pin body assembly 22 must be fixed to the printed circuit board 7, which requires double effort, and the pin body assembly 22 differs depending on the number of pin terminals 5, so the pin body assembly 22 itself must be fixed. Parts management was also time consuming.

Furthermore, as a means for implanting pin terminals 5 on printed circuit board 7 without using pin body 21, means for implanting pin terminals for rubbing connection shown in FIGS. 8 and 9 is known. With this means, the lower plate 23 supporting the printed circuit board 7 has a recess 23a provided in the printed circuit board 7 at a position opposite to the insertion hole 8. The pin terminal 5, which has been cut to a predetermined length, is held in the vertically movable top plate 24, and as the top plate 24 descends, the guide plate 2
The pin terminal 5 is inserted into the insertion hole 8 of the printed circuit board 7 while being guided by the guide hole 25a of 5. After that, the pin terminal 5 is soldered 10 to the printed circuit board 7 as shown in FIG. This provides mechanical strength as a terminal. As described above, in the case of the means for planting a pin terminal for wrapping connection on a printed circuit board, the pin body in the previous stage is not used, but the connection by wrapping in which the wire 26 is wound around the pin terminal 5 as shown in FIG. 11 is used. Since the purpose of the pin terminals 5 is to be uniform, there is no need for uniformity in the direction of the pin terminals 5, and the direction of the pin terminals 5 implanted as shown in Fig. 12 is random, and it is not suitable for pin terminals used in multi-pole housing connectors. , as shown in FIG. 13, the pin terminal 5b does not have a good connection with the terminal 12 to obtain a large contact area,
There are many 5c and 5e, and the guide plate 2
Because a No. 5 jig was used, there was a lack of freedom in the placement of the terminals.

Purpose of the invention Therefore, the present invention does not require the pin body,
Another object of the present invention is to provide a manufacturing apparatus that provides mechanical strength for wrapping pin terminals, provides uniformity in the direction of the pin terminals, and expands the degree of freedom in the placement position of the pin terminals.

Structure of the Invention In the manufacturing apparatus according to the present invention, there is provided a support means for movably supporting and positioning a printed circuit board in any direction, a supply means for supplying a long square material for a pin terminal, and a supply means for supplying a long square material for a pin terminal. a guide means for guiding a square piece for a pin terminal and correcting twisting of the square piece for a pin terminal from at least two directions substantially perpendicular to the guiding direction; a cutting means for cutting the pin terminal into lengths; a gripping and inserting means for grasping the pin terminal formed by the cutting means and inserting it into the insertion hole of the printed circuit board; and the pin terminal inserted into the insertion hole. and a fixing means for electrically connecting and fixing the printed circuit board to a conductive member provided on the printed circuit board.

Embodiments Hereinafter, a manufacturing apparatus as an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the manufacturing apparatus according to the present invention includes a rotatable drum 2 around which a long pin terminal square material 1 is wound, and a driving force applied to the drum or the pin terminal square material 1 itself. It has a feeding means (not shown) for feeding the square material 1 for pin terminals intermittently in fixed lengths from the drum. The drum 2 and the transport means constitute a supply means for supplying the long square material 1 for pin terminals. Note that the drum 2 and the transport means described above are attached to a frame (not shown) forming the main body of the apparatus.

A guide roller 3 is provided as a guide means for guiding the pin terminal square material 1 sent downward by the above-mentioned feeding means to a gripping position by a chuck 6, which will be described later, and is rotatably held by the above-mentioned frame. has been done. For example, four guide rollers 3 of the same shape are provided, and each has a V groove formed on its outer periphery to guide the pin terminal square material 1.
guide it by coming into contact with the corner of it. These four guide rollers 3 are individually pressed against the four corners of the pin terminal square material 1 with a constant pressing force. As a result, the square material 1 for pin terminal
The torsion is corrected from two diagonal directions of the rectangular cross-sectional shape, and the directions are aligned.

A pair of cutters 4 are disposed below each guide roller 3 for sequentially cutting the tip portions of the long pin terminal square material 1, which is guided and fed by the guide rollers, into a predetermined length. , and are attached to the frame so as to be movable relative to each other. Both cutters 4 are driven by cutter driving means (not shown). The cutter driving means and the cutter 4 constitute a cutting means for cutting the pin terminal square material 1 into predetermined lengths to form the pin terminals 5.

A chuck 6 is located below the cutter 4 for gripping the pin terminal 5 obtained by the cutting means. The chuck 6 is provided with a plurality of gripping claws for gripping the pin terminal 5 while being movable relative to each other. The chuck 6 is held by a chuck holding drive mechanism (not shown) and is reciprocated in the vertical direction (in the direction of arrow Z and the opposite direction), and the chuck holding drive mechanism also drives the gripping claws. It will be done. These chuck holding and driving mechanisms and the chuck 6 constitute a gripping and inserting means for gripping the pin terminal 5 formed by the cutting means and inserting it into the insertion hole of the printed circuit board 7.

A support base 9 for supporting the printed circuit board 7 to be worked on is disposed below the gripping and inserting means. This support stand 9 is moved and positioned along a plane orthogonal to the axial center of the pin terminal 5 by a support stand driving means (not shown). Thereby, the printed circuit board 7 freely moves in a plane perpendicular to the pin terminals 5 to be inserted therein. The support stand 7 and the support stand driving means allow the printed circuit board 7 to be moved in any direction.
A supporting means is configured to movably support the.

In addition to the configuration shown in FIG. 1, the manufacturing apparatus also includes a solder bath (not shown) for soldering the printed circuit board 7 into which the pin terminal 5 is inserted, and a solder bath (not shown) for soldering the printed circuit board 7 into which the pin terminal 5 is inserted. It has a mechanism (not shown) for inserting and removing the printed circuit board 7 thereinto. This mechanism and the solder bath constitute a fixing means for electrically connecting and fixing the pin terminal inserted into the printed circuit board 7 to the conductive member of the printed circuit board.

Next, the operation of the manufacturing apparatus having the above configuration will be briefly explained.

First, by applying torque to the drum 2 or by applying a driving force to the square material 1 for pin terminals,
The pin terminal square material 1 is fed out from the drum 2 for a predetermined length. At this time, the sent-out pin terminal square material 1 is guided downward by each guide roller 3 while its twist is corrected.

The pin terminal square material 1 sent out as described above is
It is gripped by the chuck 6. After this, Katsuta 4
is actuated to cut this gripped part from the succeeding part to obtain the pin terminal 5.

In parallel with the above operation, the support base 9 is moved, and the printed circuit board 7 is positioned so that the insertion hole into which the pin terminal 5 is to be inserted is located directly below the pin terminal. Thereafter, the chuck 6 is lowered and the grip is released, and the insertion of the pin terminal 5 is completed. Thereafter, the above series of operations is repeated to insert the required number of pin terminals into desired positions on the printed circuit board 7.

After that, this printed circuit board 7 is immersed in a solder bath. Then, as shown in FIG. 2, each pin terminal 5 is fixed to the printed circuit board 7 with solder 10 or the like.

Note that if a so-called X-Y table that can be moved and stopped in two directions perpendicular to each other is used as the support base 9, the placement position of the pin terminal 5 can be adjusted by controlling the movement and stop of the X-Y table. Therefore, even if there is a change in the placement position or number of pin terminals 5 during manufacture, it is possible to promptly respond to the change.

Effects of the Invention As described above, according to the manufacturing apparatus according to the present invention, the pin terminals embedded in the printed circuit board have the same direction as shown in FIG. 3, so that the multi-pole housing connector shown in FIG. The shape of the terminal 12 in the terminal 11 can be arbitrarily selected. For example, if you want to increase the contact area between the pin terminals and the terminals, specify the direction of the terminals 12 so that they engage with the pin terminals 5 planted in the same direction as shown in FIG. What is necessary is to provide it inside the housing 11.

Further, the pin terminals implanted on the printed circuit board by the manufacturing apparatus according to the present invention are shown in FIGS. 2 and 10.
As is clear from the figure, since it has the same structure as a wrapping pin terminal, it can also be used as a wrapping pin terminal.

In addition, since the pin body assembly, which has conventionally been formed once as a pin terminal group for a housing connector, is not used, the manufacturing device according to the present invention is low cost, and also reduces the man-hours required for parts management of the pin body assembly. It is something that can be done.
