Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for assembling an entire array of electrical circuit elements, such as strain gauges, spaced apart from each other with an adhesive tape.

BACKGROUND OF THE INVENTION Electrical circuit elements are generally packaged in small and microsized components and are often packaged for shipping and storage, rather than individually. Electrical circuit elements are often easily damaged and are difficult to handle because of their small dimensions. In addition, small, unstable items usually have to be precisely placed in tight spaces with great precision. Therefore, not only careful packaging is required, but also particularly skilled and skillful work is required. This requires an investment of capacity to manually position each individual element precisely at its point of use and then install it, speeding up such time-consuming and human-intensive work and reducing costs. To do this, mechanical aids are often used, consisting of more or less automated equipment.

For example, electrical circuit elements are prepared in a magazine at a distance from each other and an adhesive tape is crimped onto the electrical circuit elements via a lever, either directly or with the intervention of mechanical positioning means, and in this way Devices are known in which the adhesive tape is removed after the shaped array assembly has been transported to its destination and the individual electrical circuit elements have been mounted, for example on a circuit card. Patent Application Publication No. 1105489 and No. 112456
Publication No. 9). However, such complex and expensive equipment is only available or makes economic sense in case of bulk production or when several electrical circuit elements are to be placed together at the same time. The known devices are unsuitable if all the electrical circuit elements in the array must be placed individually.

The basic problem of the invention is to provide a device for arranging and integrating a plurality of electrical circuit elements, which avoids the disadvantages of known devices.

According to the invention, this problem is solved in the following way in an array concentrator of the type described at the outset. That is,
A circuit element is fixed to a card-like or foil-like base material using an adhesive tape, a non-adhesive partial area is provided, and a part of the circuit element and a part of the base material adjacent to the circuit element are covered with the non-adhesive partial area. It is. Immediately before its use, the electrical circuit elements can be separated by a simple cutting process and separated from their base material pieces, while still being adhered and protected by a simple and inexpensive method. The protruding part of the adhesive tape can be used to position and fix the product at the installation location. After the final electrical circuit element has been installed, the adhesive tape can be grasped by its non-adhesive portion and peeled off. It may further be pointed out as another advantage of the invention that it can be shipped in a simple container, box or the like without additional protective measures. .

In order to be able to use commercially available adhesive tapes with a continuous adhesive surface, according to an advantageous embodiment of the invention, the non-adhesive partial areas are formed as follows. That is, between the adhesive tape and the electrical circuit element and the relevant part of the substrate, the corresponding areas of the adhesive tape are covered, for example by a coating or a simple intermediate layer that solidifies the adhesive,
A non-bonded partial area is formed. Alternatively, cutouts may be provided at the appropriate locations on the base material.

Next, the present invention will be explained in detail with reference to the drawings with reference to embodiments. The figure schematically shows an embodiment of the invention.

FIG. 1 shows how individual strain gauges are assembled in an array. On the base material 1, strain gauges 2 are arranged adjacent to each other at intervals, and adhesive tape 3
It is removably attached to the base material 1 by.

The substrate 1 is, for example, a sheet of paper, a card, a plastic foil or the like. In short, it is sufficient that the surface is such that it can be reused even after the adhesive tape is removed.

The adhesive tape 3 has non-adhesive partial areas 3at-.

The partial region 3 a extends over the stonon gauge 20 portion and the adjacent portion of the base material 1 . Similarly, non-adhesive portion areas are provided at the beginning and end of the adhesive tape.

The substrate 1 is divided into individual pieces 1b by marks 1a. The marks 1a each pass through the non-adhesive partial region 5a of the adhesive tape 3 and represent the cut wire tubes which are in such a way that the individual fragments 11) can be separated together with the strain gauge 2 mounted thereon. . For example, it would be easier if it could be separated using scissors.

Figure 2 shows the separated fragment 1b. The strain gauge 2, on the side where the partial region extends up to the strain gauge, extends from the piece 1b upwardly 1C around the strain gauge edge, which is fixed to the piece 1b by means of an adhesive tape 3, as shown.
It is flapped and then separated from the piece 1b with the adhesive tape 3 adhering to the strain gauge 2.

FIG. 3 shows the strain gauge 2 separated from the piece 1b with the adhesive tape 3 adhering to the strain gauge 2. FIG. This unit is transported to the object where the strain gauge 2 is ultimately to be placed.

The strain gauge is then positioned as specified and fixed in this position by pressing the adhesive tape 3 onto the target. The strain gauge is then finally attached to the object in an unconventional manner, for example with adhesive, putty or the like, and then the adhesive tape 3 is removed.

Using an adhesive tape with a continuous adhesive surface, the adhesive bond between the adhesive tape and the substrate can be extended by means of a coating or an intermediate layer at locations intended as non-adhesive partial areas. According to another embodiment of the invention, at these points, by punching out holes or the like,
Portions of the substrate can be removed so that the adhesive tape is exposed at these points and can be easily captured.
