Description

[Detailed Description of the Invention] Recently, small electronic components such as resistors, capacitors, etc., each having a cylindrical shape (cylindrical shape, cylindrical shape, etc.) or a plate shape (square plate shape, disk shape), An automatic mounting machine or the like automatically picks up one piece from an appropriately configured supply device, places it on the printed wiring board, and connects the vagina parts on the printed wiring board in this state. (soldering, etc.).

In order to efficiently pick up small electronic components one by one and supply them to printed wiring boards, etc., the orientation of the component (vertical When it is necessary to supply components in the same orientation (for example, sideways, sideways, front, etc.), it is necessary to supply the components in the same orientation.Currently, we are currently organizing chips in such a way in advance and storing them in large numbers. Also, a tape method is used as a method for preparing for supply to the next process.

This tape method is, for example, a flexible continuous length tape A (mainly made of paper) K with pitch holes I provided at regular intervals, and the tape A (specifically, between the base tape and the thin adhesive tape 3) K. The lead wires B of various small electronic components C are glued at regular intervals (this process is called taping).
, a continuous length of small electronic component mounting tape is constructed by arranging and bonding a large number of small electronic components, and the tape is stored and transported in a reeled state. etc.) At the time of K, the reel is set on an automatic mounting machine $f, and the 11-wire B of each small electronic component C is placed in a row.
The component C is automatically and continuously cut to a certain size to separate the component C from the tape A, and the lead 41 is cut as necessary.
This process is performed by applying forming to each piece and automatically picking up each piece as appropriate. ($, Figure 1, (a), (
(b)) Recently, in addition to the above-mentioned small cypress parts, small leaf switches (length 10 to 30 m5 + f) γ, %; 3 to 8 lances) have also been developed with the same basics. There is a tendency for many to be installed and used on #t4, so
The leaf switch, as is currently being done, has its surface, after sprouting, and in the left and right directions one by one.
It is unsuitable for placement on a printed circuit board using an automatic mounting machine and other automatic pickup work, and as with the small electronic components mentioned above, it is requested that the parts be arranged in a fixed direction □ and supplied in the ■ direction. be.

Therefore, in the present invention, similarly to this leaf-in-1000 small electronic component, a large number of them are arranged on a tape in a certain direction and at a certain interval (similar to taping), and the tape is wound on a reel or the like for nine purposes. It is designed so that it can be stored and transported in the same condition, and
Use the reel with the leaf switch (installation on a printed wiring board, etc.) in the same way as with small electronic components.
When installing the switch, set it on an automatic mounting machine, apply appropriate pressure from the base of the taping arm, separate the switch from the tape, and automatically pick up one switch and place it on the board, etc. This allows for the installation of

Same, a piece of wood? Fi shows the contact of spring piece j.

Next, the above embodiment of the present invention will be explained with reference to the drawings. 1) Figure 2 shows a simultaneous molding process of the insulating base of the leaf switch D, the end piece E protruding from it, and one strip of tape A. This is an 11-flash switch array tape DEA integrally constructed by the following.

Although not shown in the drawings, the leaf switch arrangement tape DEA is manufactured using a plastic mold, for example, by forming recesses in the shape of 10 leaf switches D (insulating base plate, presser 6, separator 7, and contact spring piece 3 to be inserted). mold part)
At the same time, a thin rod-like arm E-shaped recess (mold) is continuously provided in the insulating base's wide-shaped recess, and a flat string-like tape A-shaped recess (mold) is continuously provided in the arm-shaped recess. A series of recesses were made, a flat mold was provided, and an appropriate plastic was injected into the plating mold, and 10 glue switches were integrally arranged at regular intervals on tape A with end marks E. For example, by molding a product, for example, molding a small uneven portion 1o and a small hole // at the end of the tape A, the next time the molding process is performed, only the part of the rolled product is placed in the tape mold. The leaf switch array tape DEA can be made into a continuous length of leaf switch array tape DEA by leaving it behind and connecting the tape ends by double injection molding in the next molding, or by connecting the tape ends by other appropriate methods.

Note that the tape part A is formed, for example, into a flat string-like body with pitch holes L formed at equal intervals, but since it is wound into a reel, a certain degree of flexibility and pliability is required. Select 94 the plastic material to be used in that direction. 8. □1.
2) Figure 3 shows that the ends E and E protruding from both the insulating base ψ and the presser 4 of the leaf switch D and two parallel tapes A%A are integrally formed by simultaneous molding. This is the constructed leaf switch array tape DEA.

3), Fig. 4 shows an integrated arm E and tape A protruding from a street-sealing type cover t that covers and fits around a contact spring j, and a leaf 2 D. A terminal E protruding from the insulating base V and a tape A integrated 13 are provided (Fig. 4, (A)), and each of the two sealed covers 1 is connected to each of the 13 leaf switches. Leaf switch array tape D' configured by fitting onto the contact spring piece S portion of D.
It is EA (I [Figure 4, (b)).

In addition to the above-mentioned example, the above-mentioned sealed cover t can be fitted or the tape D'EA can be used to tape only the sealed cover j of the leaf switch D to which the sealed cover l has been fitted in advance. A configuration in which E is connected to a single tape 8, and conversely, a configuration in which only the insulating base DA of a leaf switch D, to which a sealed cover T is fitted in advance, is connected to tape A by an arm E. , Furthermore, a sealed cover is subsequently fitted to the leaf switch arrangement tape D'EA in the upper (/on state) to form the leaf switch arrangement tape D'EA.
A simple example of a configuration is possible, such as .

The above-mentioned sealed cover t was originally developed by the applicant as a special face 1i8.
The patent application was filed with No. 56-202974 and No. 57-41575, and most of the circumferential surfaces of the multiple contact spring pieces of the leaf switch (excluding the base) are in a state that does not interfere with the operation of the switch. It is covered.

The switch array tape DKA of the present invention has the above configuration.

D'EA can be stored and transported in its continuous length by winding it up on a reel, etc. or in a reel shape, and when conveniently used, it can be stored and transported using an existing small electronic component array tape device or similar device. It is possible to set it in a similar device, cut the base of arm E, separate leaf switch D% D' from tape A, automatically pick up the switch, and install it on a printed wiring board, etc. Unlike the case where each piece is supplied in various directions and postures such as front and back, left and right, front and back, it is similar to the current supply of small electronic components. (both in terms of time)
This has the excellent effect of making it possible to continuously supply leaf switches to the next authority at each time, and realizing highly efficient and accurate switch installation.

As mentioned above, the gist of the present invention is a leaf switch arrangement tape that is constructed by integrally forming the plastic wire part or sealed cover of various types of glue, end, and tape by simultaneous molding. Naturally, the shape of the insulating base and the shape and structure of each component of the leaf switch are completely arbitrary and are not subject to any shape or structural limitations. All switches called l-f switches,
For example, normally open type switches (as shown in the example shown in Figure 2), normally closed type switches (switches whose contacts are closed under normal conditions), switches that combine both types, their ponds, and contact strips. This applies to all items, including items with two pieces, items with three or more pieces, and items with a set of tumblers.
