In place of the fixed board positioning part 110, a movable board positioning part 6 is arranged along the idle rail 3 in the part where the movable insertion unit 5B is arranged.

When the printed circuit board 2 transferred by the conveyor unit 1 stops at the fixed insertion unit (5A), the fixed board positioning section 110 clamps the printed circuit board 2.
An electronic component is inserted into a specific position of the printed circuit board 2 by the insertion section 7 of the fixed insertion unit 5A, and a clinching operation is performed by the clinch section 8 on the lower side of the printed circuit board 2.

When the printed circuit board 2 stops in front of the movable insertion unit 5B, the printed circuit board 2 is clamped by the movable board positioning section 6, and the printed circuit board 2 is positioned at a predetermined position in the X direction. Furthermore, by moving the Y table 37 disposed on the base 7 frame 10 in the X direction, the insertion section 7 and the clinch section 8 are positioned at a predetermined position in the X direction, and electronic components are inserted into a specific printed circuit board position. , a clinch is held. This positioning in the X and X directions is usually performed multiple times, and electronic components are inserted and clinched at multiple locations on the printed circuit board.

”In the case of the Uni embodiment, the removal of the insertion units 5A and 5B
j. Removal is extremely easy, and it can be quickly adapted to changes in printed circuit board models and inserted parts.

In addition, in the case of the movable insertion unit) 5B, a movable board positioning section 6 that clamps the positioning holes of the printed circuit board from above and below to position it in the This eliminates the need to transfer the printed circuit board from the belt conveyor to the X-Y table, and makes the movable insertion unit (5B) independent from the conveyor unit 1, realizing modularization.

Furthermore, in Yokudai Unino) 5A and 5B, since the supply section 14 is integrated within the unit, the operation of the insertion section 7 to pick up electronic components from the electronic component delivery position P of the supply section 14 is difficult. It is constant, and cycle time can be shortened.

Purchasing of each unit is simplified, and an inexpensive electronic component insertion device can be obtained.

It is clear that the specific shapes of the insertion section 7 and the clinch section 8 can be changed as appropriate depending on the type of electronic component.

(Effects of the Invention) As explained above, the in-line electronic component insertion device of the present invention can quickly respond to model changes and component changes by making the insertion unit detachable from the conveyor unit. This has the advantage of shortening setup time.
