BACKGROUND OF THE INVENTION
The present invention relates to an electronic component insertion apparatus for automatically inserting a lead wire of an electronic component into a predetermined hole of a circuit board and mounting the electronic component on the circuit board.
[0002]
[Prior art]
A conventional electronic component insertion apparatus will be described with reference to FIGS. A pair of movable blades 13a and 13b and fixed blades 14a and 14b are provided for cutting off and removing excess portions at the ends of the lead wires 12a and 12b extending to both sides of the electronic component 11, respectively. The fixed blades 14a and 14b are disposed on the outer side, and the movable blades 13a and 13b are disposed on the inner side. And inside the movable blades 13a and 13b, when the lead wires 12a and 12b are cut and bent, the lead guides 12a and 12b are bent and guided to the predetermined holes 9a and 9b of the circuit board 9, respectively. Pushers 16a and 16b for holding the lead wires 12a and 12b and inserting the lead wires 12a and 12b into the predetermined holes 9a and 9b of the circuit board 9 are sequentially arranged. Further, between the pushers 16a and 16b and the circuit board 9, a molding lever 18 that receives the lead wires 12a and 12b from the lower side is arranged so as to move forward and backward in synchronization with the vertical movement of the pushers 16a and 16b. ing.
[0003]
Next, a method for inserting the electronic component 11 will be described with reference to the operation flowchart of FIG. 9 and FIGS. When the electronic component 11 is introduced between the movable blades 13a and 13b and the fixed blades 14a and 14b and the molding lever 18 advances to the space below the electronic component 11, the pushers 16a and 16b are lowered as shown in FIG. Then, both side portions of the lead wires 12a and 12b of the electronic component 11 are pressed against the upper surfaces 18a and 18b of the forming lever 18 and sandwiched from above and below. Next, the movable blades 13a and 13b are lowered to cut the lead wires 12a and 12b from the fixed blades 14a and 14b. Next, as shown in FIG. 11, the insertion guides 15 a and 15 b are lowered, and the lead wires 12 a and 12 b are bent so that their respective tips can be inserted into the predetermined holes 9 a and 9 b of the circuit board 9 from directly above.

[Problems to be solved by the invention]
However, in the above-described conventional configuration, the V-shaped grooves 17 on the lower sides of the pushers 16a and 16b have a margin of about ± 0.3 mm with respect to the lead wire diameter, so that the lead wires 12a and 12b are bent by 0.3 mm or more. In this case, the lead wires 12a and 12b are detached from the V-shaped groove 17, so that the lead wires 12a and 12b cannot be bent and the electronic component 11 cannot be inserted.
[0006]
In view of the above-described conventional problems, the present invention provides an electronic component insertion device that can accurately insert an electronic component by adjusting the lead wire to a predetermined position even when the lead wire is slightly bent. It is aimed.
