[Means for solving problems]

In order to solve the above-mentioned problems, the present invention is directed to a component supply unit capable of adjusting the supply height of a lead electronic component to an arbitrary height and a lead type electronic component supplied from this component supply unit. Between the lead of the lead-shaped electronic component molded by this molding portion, the lead of the component is clamped and the lead is bent and molded into a predetermined shape when clamped, and the molded lead-shaped electronic component is transferred. A cutting unit that cuts the tip, and an insertion unit that holds the lead-shaped electronic component, in which the lead transferred from the lead molding unit is molded and cut, and inserts the lead-shaped electronic component into the circuit board up to the bent portion of the lead, and It is characterized in that the lead forming part and the cutting part are connected through an interlocking mechanism, and the leads of the lead-type electronic component are clamped, formed and cut at the same time.

[Action]

The component supply unit can arbitrarily set the height of the supply position of the supply component, and supplies the set electronic component by setting it to a predetermined height.

The lead forming unit sandwiches the electronic component supplied from the component supply unit to form the lead in a non-linear form, for example, in a polygonal line shape, and the cutting unit cuts the tip of the lead to separate the electronic component from the tape, The electronic component in which the lead has been molded and cut is transported by sandwiching the lead in the lead molding portion, transferred to the insertion unit, and inserted into the circuit board.

The component supply unit is designed to supply components by setting the height to a predetermined height according to the insertion height of the electronic component to be inserted into the circuit board. When the lead is molded into a polygonal line shape, the height position between the molded portion and the electronic component body can be set to a predetermined height. The tip of this lead is cut at the cutting portion. Since the electronic components whose leads have been molded and cut are transferred to the insertion unit and inserted into the circuit board, the electronic components have a predetermined height on the circuit board due to the engagement between the molded lead bent portion and the upper surface of the circuit board. You can insert it.

The insertion operation continues in the order described above.

If the same electronic parts have different insertion heights (h in Fig. 16) to the circuit board, the above (b) and (k)
As described above, by merely changing the supply height of the electronic component 2 in accordance with the preset order, the insertion height can be changed and inserted during the continuous insertion work.

〔The invention's effect〕

According to the present invention, an electronic component having a straight lead which has not been formed is taped and is supplied by a component supply unit capable of setting a predetermined supply height, and the lead forming unit supplies the lead of this electronic component. It is sandwiched and molded into a non-linear shape,
The cutting unit cuts the tip of the lead to separate the electronic component from the taping, and the molded and cut electronic component is transferred to the insertion unit and transferred by the lead molding unit, and the insertion unit clamps the electronic component. Since it is sandwiched by and guided by the insertion guide to be inserted into the circuit board, the lead molding position can be changed according to the supply height of the electronic component, and the height of insertion of the electronic component into the circuit board can be set to a predetermined value. You can set the height and insert the electronic components.

According to the present invention, in the conventional example, even when the same electronic component has different insertion heights into the circuit board, all types of taped electronic components are prepared by forming leads to different heights in advance. In addition, the problem that arises when it is set again in the component supply unit and used is solved. That is, it is not necessary to prepare various types of electronic components having different heights, and the taped electronic components with unmolded leads can be changed in the lead molding position only by changing the supply height. It is only necessary to prepare one type of taped electronic parts, which simplifies the packing style, reduces the electronic parts procurement cost and management cost, and changes parts according to a preset order when the insertion height is changed. Since it can be dealt with only by changing the supply height of the product, it is possible to obtain the flexibility to change the specification and to have the ability to quickly respond to the production of a wide variety of products, solving the problems of the conventional example. It is possible to provide a device for inserting the electronic component.
