Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to electronic components and improved mechanized assembly thereof.

(Prior Art) In order to manufacture and assemble a large number of electronic/electrical products at low cost, it is necessary to establish an efficient mechanized method for joining electronic components to printed wiring boards and other crafts.

Currently, there is a mechanized method for attaching electrical hard parts such as terminal pins, tabs, sockets, etc. to workpieces as appropriate, but many other component parts still need to be assembled by hand.

For example, in U.S. Pat. No. 4,318,964,
An apparatus is disclosed that includes a feed strip for inserting a terminal into a substrate or a workpiece.

To fit the pins into the printed wiring board (PIIIB), one pin is separated from the other pins forming the strip and press-fitted into the PITlB. A device of this type is also disclosed in US Pat. No. 4,807,357.

The feed strip is a continuous strip of metal pins wound on a reel.

Existing approaches incorporate pins, tabs or sockets into the board. The pin fitting device allows pins of different sizes to be fitted into the apertured workpiece. Not only can the cross section and length of the pin be changed, but it can also be bent 90 degrees or held straight.

This device is continuously fed with pins (pre-notched) wound on reels. The pin is fed out, cut and formed, and then inserted into the workpiece below the insertion device. The fitment hole and pin can be aligned by manually positioning the workpiece below the fitment head, or automatically by a computer-controlled X-Y positioning table with PVB.

Using similar equipment, sockets, tabs and other parts are
Can be inserted into IIB. For any socket pattern,
Can be mechanically or manually fitted into plastic housings.

The above method is characterized by the means for fitting the pin or socket into the board. In other words, one pin each time,
This is accomplished by fitting a socket or tab.

As another conventional method, a method has been proposed in which a large number of pins (up to 50 at a time) are inserted simultaneously, but this involves the steps of storing continuous pin parts with headers for supply and installing them from a reel. It is similar to the above method in point (d). The difference is that the pins are first inserted vertically into the protruding plastic header and then stored on the supply reel. The endless electrical connector described in U.S. Pat. No. 4,832,622 is an example. With this device,
Automatically separates the header with the desired predetermined amount of pins from the supply reel. First, the header is inserted into
Fits into VB.

Although this equipment can increase efficiency in the assembly of certain automated parts, other hard parts are not fully automated.

Below are three examples of components that could not be mechanically assembled up until now.

A first example of electrical components that are individually manually assembled is the electrical shunt connectors or jumpers used in fishing boats to interconnect pins to form, for example, a printed circuit board. .

The plastic body of the flow divider is individually molded.
The pins on which the shunt is to be erected are installed accordingly by inserting stamped metal conductors therein and then manually attaching the completed shunt assembly to the PUB pins using a template or a light beam.

This method requires intensive manual labor and high labor costs.
If the shunt is improperly installed, the board must be rebuilt.

A second example of an important electronic component is a wire end terminal. The process of assembling terminals to wires has not yet been automated. The end terminals must be positioned on the wire, which is done individually by hand. A method for mechanically assembling these parts has not been developed.

As a third example, a long cone-shaped metal conductor pin row is
It may get stuck. Inconveniences occur when connecting female connectors6. For example, if the connectors are not assembled uniformly along the pin axis, the pins may bend when the connectors are connected, and if the connector is used with tall pins, ,
The problem will become even more serious. Typically, a barbed header with an integrally molded pilot on either end prevents pin bending.

First, the female connector is opposed to the pilot (which is higher than the pin) to ensure that the axes of the pin and connector are properly aligned. However, this type of header is expensive and the construction and assembly of a particular connector is time consuming.

The common disadvantages of the above three assembly examples are that they are expensive and that the loose fitting pieces must be handled individually during the manufacturing or assembly stage. This takes time and money. Furthermore, servicing and storing loose-fitting electronic components is costly.

Although the problems in the three types of components described above are particularly severe, there are other components that present similar manufacturing and assembly problems.

(Problems to be Solved by the Invention) A first object of the present invention is to provide a method for efficiently mechanizing the manufacture and assembly of electronic components.

A second objective of the invention is to integrate more aspects of manufacturing and production so that the final product can be produced more efficiently and at lower cost.

A third object of the present invention is to prevent or minimize the need for individual processing of loose fitting parts during the manufacture and assembly of electrical components.

A fourth object of the invention is to automate the manufacturing and assembly of electrical shunt connectors.

A fifth object of the invention is to mechanize the attachment of insulation posts to the PWB that serve as pilots for the connector.

A sixth object of the invention is to fully automate the production of wire terminals and their incorporation into wires.

SUMMARY OF THE INVENTION The above-mentioned objects and others are achieved by a novel method of molding an endless array of plastic parts.

When the shape of the part is complicated like the above three parts, a continuous injection molding method is preferably used. After winding the endless part string onto a reel and forming it into a reel shape, the reel-shaped parts can be processed into zero parts or crafted items that can be processed at a high production rate by using known automatic equipment as is or with simple modifications. Before completing its incorporation into, it is necessary to subject it to several stages of mechanical processing.

This allows the plastic part to be drilled, fitted with metal parts, or subjected to other secondary treatments before the reeled part can be sent to a device for rewinding the worked parts. Another path through the embedding apparatus allows one or more parts to be cut off from the supply reel, as desired, and each part to be applied to the workpiece as appropriate. In this way, more production processes can be automated.

A feature of the invention is that the continuous molded product is initially formed on a reel. The zero-order reel, which can vertically stack and store a large number of plastic parts in various shapes required for specific applications, is attached to the above-mentioned assembling, inserting or crimping device.

Providing an endless series of parts that attach or mate with another mechanically aligned part. Subsequent manual transport of the supply reel between or from the equipment to a customer equipped with a similar applicator using this type of reel and allowing automatic loading of the reel-like parts onto the PIilB is facilitated.

Thus, the invention is flexible and flexible in the variety and quantity of parts that are manufactured and attached to the corresponding workpiece.

In accordance with a preferred embodiment of the invention, the flow diverter connector is manufactured by injection molding a continuous series of plastic bodies and winding onto a first reel. For automatic assembly, the first reel is attached to the device.

The device is then fitted into each body portion through metal contact spring clips received from a metal parts source before the second
Rewinding the reel, the second reel is placed on another insertion device, which separates the plastic body with metal contact spring clips from the endless supply and inserts a properly positioned PCB (printed circuit board) underneath. to the pin terminal of
Wear this.

In accordance with another preferred embodiment of the invention, wire end terminals are manufactured by forming an endless array of plastic parts similar to those described above that can be crimped onto the leads and winding them onto a reel. It is delivered to the device, and in a secondary process, a metal tube connector is fitted, and after wire feeding, the metal connector is fitted with a stationary crimp.

According to a third embodiment of the invention, a continuous row of plastic posts is molded, wound onto a reel, and inserted into the PWH from the reel feed by the above-described insertion device.

Therefore, reel-fed automatic fit-in assembly is an endless series of plastic molded parts that are sequentially processed and reprocessed to minimize the manual processing of loosely fitting parts. It is clear that electronic components can be manufactured and assembled efficiently.

Broadly speaking, the method of the present invention consists of (1) molding, (2) reeling, (3) secondary processing and rewinding of the assembly as desired, and (4) fitting.

Assembling, fitting and crimp-fitting devices are known and are achieved by integrating a supply reel of continuous pieces of electronic components. Manufacture of electronic components.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION A method of efficiently mechanizing assembly and insertion is described.The method of the present invention minimizes manual handling, cost, and time required for manufacturing and assembling electronic components.

The invention also includes supply reels of novel components, assemblies, subassemblies, and parts produced as intermediates or final products by practicing the methods of the invention.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before that, as background of the present invention, FIG. 1 shows the starting point of the present invention, that is, the injection molding method. This is disclosed, for example, in US Pat. No. 4,832,622, which is cited as reference material.

Preheating, plasticizing and molding are all done in the same equipment. From the hopper opening (12), the plastic granules (10) are fed into the injection cylinder (19) and are heated to the molten state (13) in the cylinder (19) by means of the heating jacket (14). The molten plastic is then injected with a ram (15) into a mold (16) as shown in FIG.

The mold (16) forms individual quantities of plastic parts (17) all interconnected by separable plastic flakes or webs (18).

During the forming process a web (18) is also formed. At the end of each part/web completed piece there is an end extension or web (27).
and its free end is placed back into the mold to form and fuse the next part strip.

This step is performed following each molding step. In this way, endless or continuous long strips of plastic parts can be produced while being held by the web (18).

All plastic parts, except the first and last parts, which have a joint only on the - side, are interconnected with separable plastic flakes or webs.

1 to 3 show the manufacturing procedure for the flow divider housing (17). The flow divider housing (17) has a third
As shown, they are interconnected by webs (18). As each component strip is formed, it is connected to the next component strip with a web (18) as described above.Next, the continuous strip of diverter housing component (17) is wound onto a reel (20) and assembled. The attachment is sent to the device.

For this assembly, the device is fitted with a metal spring clip (25), with the metal clip fitted onto the continuous strip.

This state of rewinding onto another reel (21) is shown in FIG.

Since a device of the above type has been disclosed and is already commercially available, only the insertion head (23) of the formed metal spring clip is shown in FIG.

The metal spring clips (25) are supplied from continuous part reels interconnected by webs. Assembly is a secondary operation of the device, removing the spring clip from the strip fed along the chute (24) and ramming it into the diverter housing.

FIG. 5 shows the metal spring clip (25) fitted into the strip plastic flow divider housing (17);
) to lock it into the housing. Ascending lock (29)
) makes it easier to push the metal insert into the housing and makes it more difficult to remove it over the step in the housing.

Place the completed flow divider (with spring clip) on the reel (21)
Wrap it around.

For clarity, FIG. 6 shows the spring clips fed down the chute (24) as separate items. As described above and as is known, the spring clip can be stamped, wound into a continuous strip, and fed from a reel to the assembly shown in FIG. The reel (21) is then rotated so that the open end of the shunt section faces down and fits onto the PCB terminal. The rolled reel (21') is then mounted on another device that separates each flow divider (17) from the strip, and it is fitted into position on the PCB pin terminal.

Figure 7 shows how the supply reel (21') feeds the diverter strips one by one into the insertion head (31) of the device which is fitted into the PCB board (32). Insertion head (3
1) of the x-y desk (36) of the device positioned under
On the CB board, there are several complete shunts (34) fitted to its pin terminals (35).

Figure 8 shows the X-Y console (36) and the PCB board (32), with the left PCB board terminal (35) fitted with a 1st shunt (34), and the right side Terminal (35)
Another flow divider (34) in the mating head (31), which is being cut off from the continuous strip along the web (18) by the shearing tool (37), is mated by the ram (38). is about to be combined.

Figures 9-11 illustrate the manufacturing of a plastic housing or insulating sleeve that forms part of a wire end terminal.

Using the above injection molding method, the wire end terminal (17')
manufactures tapered plastic insulators.

A mold (16') forms discrete quantities of plastic parts (17') interconnected by separable plastic flakes or webs (18'). At the end of the component strip there is a web extension (27') which is then placed in a mold formed as described above and fused to the next strip.

Figure 12 shows a continuous strip of plastic parts being reeled (4
0) and feeding it into the 1 assembling device head (42). As a secondary operation, the erection device fits the flared hollow metal tube into the insulating sleeve to form the wire end terminal. One method is to feed the loose fitting flared hollow tube parts into the assembly machine using a hopper and then an escape mechanism, align the parts, and then feed them one by one to the assembly head where the ram , and insert it into the insulating plastic part.

Figures 12 and 13 show an alternative approach.

That is, the hollow part of the wire tube (43') is connected to the reel (
From the tubular feed strip wrapped around the shearing tool (37'
) and make one end wide or flared,
Fits into the tapered portion (28) of the plastic housing part (17'). Next, a wire end terminal piece (tapered plastic part (17') is placed on another supply reel (41).
)) Wind up the flared hollow wire piece (43') fitted into the

FIG. 13 shows a chute (46) with a shearing tool (37') for cutting a piece of hollow wire (43') from an endless hollow wire strip (43). Hollow wire (43')
into the chute (46) and cut the shearing tool (37').
and then fit into the tapered plastic housing part (17'). Flare one end of the hollow metal tube.

Fit hermetically into the insulating sleeve. On the supply reel (41),
Tapered housing parts (
17') is wound up.

The reel (41) is then mounted on another crimping or crimping device and the insulated wire piece (47) is inserted into the wire end terminal (17).
'). One method is to use insulated wire (47
) The ends (45) are peeled off and then lowered into the chute (44) and sent to the insertion head.

Figure 14 shows the insulated wire (47) being lowered vertically into the chute (44) and fed into the insertion head of the device (49).

As shown in FIG. 15, the bare wire end of the insulated wire is inserted into the wire end terminal assembly and crimped into place. The crimp tool (48) is used to attach the insulated wire (47), the wire end terminal (
17') Crimp fit the exposed wire part inside the plastic part and the hollow metal wire part (49') of the wire end terminal.

The resulting workpiece is then cut off from the feed strip wound on the reel (41) with a shearing tool (37'), as shown in FIG.

Figure 17 shows the final product obtained from the above process, namely a piece of insulated wire (47) crimped onto a wire end terminal (17').

Alternatively to the method shown in FIGS. 14 and 15, the device can be easily combined with known wire strippers and crimpers. In this case, the 1 sent out from the reel
Peel off the front end of the continuous wire of the book, cut it to the appropriate length,
Peel the trailing edge and crimp it onto the terminal end as shown.

As yet another example, the stripped wires can be placed in the crimp head (49) in sequence and manually inserted into each terminal according to (d).

Figures 18 to 20 show pilot plastic columns (p
ost) injection molding method is shown. This method is as described above. End of each column (50) (so'
) is one-sided. The base (51) is enlarged and has a wide plastic strip (52) spaced apart from the enlarged part (51).
).

FIGS. 18 and 22 show the slit (55) formed at the bottom of the column. The slit (55) extends from the central band (52) through the enlarged portion (51) to the bottom;
Although the pillar bases are shown as parts, these parts can be formed by the same injection molding method as described above.

The mold forms discrete quantities of plastic parts (17') connected to subsequent plastic parts by separable plastic flakes or webs (18'). The final web (27') is fused with the subsequent mold in an extended web to form a continuous strip. For this process, the continuous partial strip is placed on the supply reel (53
) and sent to the insertion head (31') of the insertion device, where it is cut into pillar sections and inserted into the alignment holes (54) of the PCB board (32'). The PCB board is an X-Y table (36
) so that the pillar (17') can be passed through the PCB board and locked in place.

Figure 22 shows the shearing tool (37') cutting each pilot column (17') from the continuous feed strip, extruding it with the ram (38') and placing it on the PCB board (32'); .

This shows how to use the characteristic parts of the plastic pilot column. The bottom chamfered edge allows easier alignment of the post during insertion. The part (17') is locked in place by pushing the enlargement (51) through the hole (54) and inserting the post into the workpiece. A slit (55) forms a bifurcated end, which contracts during insertion and then expands to lock and hold the enlarged portion in place. The wide strip (52) acts as a stop and allows the pillar to be extruded to hold the workpiece or PCB board (32'
).

The other chamfered edge (50'5) protrudes onto another electronic component of the PCB board.

Next, a header (not shown) with multiple metal pins is installed between the two columns (17') shown in the 21st figure.

The two posts guide the female connector assembly onto the pins and prevent it from bending as described above. Alternatively, metal pins can also be inserted separately between the pilot posts (17') of the PCB board.

As mentioned above, the details of the embodiments of the present invention have been described, but the present invention is not limited thereto.

Of course, it can be modified in various ways without departing from its scope of application.

(Effects of the Invention) As can be seen from the above description, according to the present invention, most of the processes that were conventionally performed manually can be automated, thereby reducing the manual labor required to manufacture and assemble electronic components.

Cost and time can be minimized.
