Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for storing small parts and a storage strip.

Specific examples of small parts include small electronic parts such as capacitors, resistors, and semiconductors, other precision machine parts, and the toy equipment industry. - Further, the present invention relates to a storage method for the purpose of smoothly supplying these parts at a work site, and an end-shaped storage strip used directly in this storage method.

(Prior art) For example, the small electronic components such as capacitors, resistors,
Due to the small size of semiconductors, there is a risk of them being lost, falling off, or becoming separated, so it is necessary to pay close attention to their storage and handling. Various storage methods have been proposed to maintain a constant supply.

- A storage method using a plastic wrapper is being implemented.

In this storage method, the strong mount tape Qυ is provided with perforations □□□ along with the adhesive tape @ at a constant pitch in the length direction, and the mount tape Q1) and this mount tape ■υ are pasted. The two lead wires (C) and (C) of the capacitor (B) are sandwiched between the adhesive tape (A) and the capacitor (B), and the capacitors (B) are arranged continuously at a constant pitch on the backing tape Cυ. The backing tape with (b) arranged in series is stored by winding it around a cardboard reel or folding it into a flat pack.

Then, during the process of planting this capacitor on a printed wiring board using a mounting machine, the mount tape stored in the reel or pack is sequentially pulled out,
An endless tractor belt or sprocket with conical protrusions protruding and recessing at a constant pitch on the back side of a toothed belt is engaged with a sprocket hole drilled in the backing tape, and the backing tape is attached to the mounting machine at a constant speed. That is, the capacitors are supplied and placed on the printed wiring board at a high speed of 0.5 seconds per capacitor.

(Problems to be Solved by the Invention) However, in the method for storing small parts using a filter paper tape made by laminating the above-mentioned mount tape and adhesive tape,
Due to the insertion misalignment of small electronic components into the paper tape, it is difficult to ensure the positional accuracy of the lead wires, and because the electronic component lead wires are held between the backing tape and the adhesive tape, the lead wires may be deformed. This is easy to occur, and some of the adhesive from the adhesive tape adheres to the lead wires, so the presence of this adhesive makes it difficult to solder onto printed circuit boards, and the paper used to attach small parts The removal work from the manufactured tape is difficult due to the presence of adhesive, and furthermore, the paper tape after parts removal has no choice but to be discarded, and the material loss due to use cannot be ignored. There were many problems such as.

The present invention solves the above-mentioned problems of the conventional devices, and enables simple storage of small parts and subsequent smooth supply of small parts to predetermined positions. The purpose is to provide a storage strip for direct use.

(Means for Solving the Problems) In order to achieve this object, the present invention has the following configuration.

That is, the method for storing small parts, which is the first invention of the present invention, is to provide a gap at a predetermined pitch on the back surface of a rubber-like elastic band with ends, and to sandwich at least a part of the small part with the gap. In addition, the band-shaped body is characterized by a configuration in which the band-shaped body is wound in a spiral shape with the gap portion located inside, and the second band-shaped body for storing small parts used directly in the first invention is , gaps are provided at a predetermined pitch on the back side of the rubber-like elastic end-shaped strip in which the tensile material is embedded, extending in the width direction of the strip into which at least a part of the target small part can fit. It is characterized by a structure in which the body is provided with means for ensuring synchronous drive at a constant speed and at regular intervals in the longitudinal direction of the strip body.

The band-shaped body used for storing small components has been further developed and is also used as a part of a supply means to a mounting machine that is operated to attach small electronic components to a printed wiring board or the like. An example of this will be described using the schematic explanatory diagram shown in FIG. 9. At least a part of the electronic component according to the present invention is inserted into each gap formed on the back surface of the strip and rolled up in a spiral shape.

(Effects of the Invention) The present invention provides at least a portion of the article in accordance with the shape and form of the intended small article on the elastic protrusion or elastic protrusion provided on the back surface of the rubber-like elastic band. By forming a gap with a shape suitable for clamping, and clamping the part inserted into the gap using the elastic force of the band, and by winding the band in a spiral shape, small parts can be held together. The clamping force due to the elastic force of the strip is further increased, and the storage effect of maintaining a constant orientation of the article becomes more reliable.

In addition, by appropriately changing the shape and form of the gap formed on the back of the strip according to the shape and form of the parts to be stored, this strip can be used regardless of whether it is a chip type or a component with lead wires. , each tray can be widely used for storing small parts.

Furthermore, when attaching and removing parts to and from the strip-shaped body, the opening amount of the N1ffi portion can be freely expanded by bending the strip-shaped body, making it easy to attach and detach the parts.

In addition, by using the elastic force of the strip to attach the parts to the strip, the parts themselves can be stored firmly and reliably, and the adhesive can be used like the above-mentioned #1 tape. This adhesive does not stain the parts that would be caused by using the adhesive, and this greatly contributes to smooth work in the future.

In addition to storing small parts in an orderly manner, this belt-shaped body can be made to travel at a constant speed and at regular intervals by means of synchronous drive such as protrusions or feed holes. It becomes possible to supply parts to predetermined positions with high precision, and this strip-shaped body can be used repeatedly over a long period of time, so that overall product costs are effectively reduced in the long run.
