Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electronic circuit mounting component insertion machine.

[Summary of the invention]

The present invention uses an electronic circuit mounted component insertion machine to insert electronic circuit mounted components with thick leads, and to easily perform clinching by performing lead processing to reduce the clinching force during clinching before insertion. It's something that makes it possible.

[Conventional technology]

An example of conventional electronic circuit mounting component insertion is shown in a cross-sectional view in Figure $4. Reference numeral 14 denotes an insertion component body, which is composed of leads 15 having a cross-sectional area of φα8 mm or more. A circuit board 16 has an insertion hole 17 into which the lead 15 is inserted.

The relationship between the lead 15 and the insertion hole 17 is a press fit relationship,
Lead 15 is press-fitted into the insertion hole 17 by inserting pressure into the component body 140 from above.

[Problems and Objectives to be Solved by the Invention] However, the above-mentioned prior art has problems such as tight fit between the board and the lead, cutting of the insertion hole and land pattern, and problems with the insertion hole. The problem is that stable insertion cannot be achieved even if there is a slight variation in the doyoi degree.

In addition, if you attempt to insert a thin lead with a cross-sectional area of 65 mm or less into an automatic insertion machine for circuit-mounted components, problems may occur such as damage to the board and large stress being applied to the electronic circuit-mounted components. It's coming.

The present invention is intended to solve these problems, and its purpose is to provide a thin lead electronic circuit mounting component φ[16
It is an object of the present invention to provide an automatic insertion machine that has the ability to clinch electronic circuit mounted parts with thick leads as well as an automatic insertion machine equivalent to a cross-sectional area of 5 mm or less.

[Means to solve Ma Zhao point]

The electronic circuit mounting component automatic insertion machine of the present invention has a diameter of φ (18 mm).
A feature of the present invention is that it has a function of reducing the lead cross-sectional area of an electronic circuit mounted component having a lead ft equivalent to the above-mentioned cross-sectional area.

[Effect]

According to the above configuration of the present invention, by processing the parts to be clinched in advance, the clinching force at the time of insertion can be achieved by using the amount of electronic circuit components with thin leads. A vertical cross-sectional view shows an example of lead processing of the clinch portion before insertion in an electronic circuit mounting component automatic insertion machine. 1.5 is the inserted component body, 2
．． An electronic circuit mounting component is constituted by 6 leads with a diameter of 8 mm in cross section.

In the figure, each piece is processed into a crushed shape using a crushing tool 8. FIG. 3 shows a vertical cross-sectional view of the inserted state after the parts are clinched. 9 is the main body of the part, and 10 φ (1
An electronic circuit mounting component is constructed with an 8mm lead, and 11
0 board has a text insertion hole 13 corresponding to 10 IJ-cards,
The lead 10 is inserted into the insertion hole 13, and is clinched from the V-notch 3 and the crushed portion 70 using 12 clinch tools. In this example, V-notches and crushing are described, but if the function is to reduce the cross-sectional area, it can be cut, punched with a press, or shaved with a file.

It may also be a device that has functions such as picking up. Further, the cross-sectional shape of the lead may be an ellipse, a square, a rectangle, a triangle, or other polygon. Note that the cross-sectional area of the lead may be equal to or larger than φO, am.

〔Effect of the invention〕

As stated above, according to the present invention, electronic circuit components with thick leads can be automatically inserted without damaging electronic circuit components or boards by processing the leads with a function that reduces the cross-sectional area of the metal. Clinching can be easily performed.

As a result, automatic insertion into products with conventionally high reliability guarantee levels is difficult, and automatic insertion is possible in the T field.

However, in the conventional press-insertion method, the movement of the electronic circuit board after insertion is difficult due to vibrations caused by transportation by truck, making it difficult to transport it from an automatic insertion factory to a remote location.This problem has also been solved.

Furthermore, there is no need to apply large stress to the electronic circuit component body during insertion, which improves the safety of the electronic circuit component during insertion.
