Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Field of Industrial Application) The present invention relates to a component mounting device for inserting electronic components onto a substrate such as a printed wiring board.

(Prior Art) Conventionally, as a component mounting device for attaching various types of electronic components to a substrate such as a printed wiring board, there is a device such as the following).

FIG. 3 shows a conventional component mounting device, in which reference numeral 1 indicates a horizontally articulated component insertion device.

A rotary head 3 is attached to the distal end side of the arm 2 of the component insertion device 1, and a plurality of jacks 4 are arranged around the circumference of the rotary head 3 to match the shape of the component. Also, a moving table 5 that moves in two horizontal axes is provided near the component insertion device 1, and a plurality of clinching devices 6 that match the shape of the component are provided on the moving table 5. has been done. This clinch device 6 is designed to detect conductive legs of a component and bend or cut the component. Further, above the clinch device 6, a substrate 7 is provided.
is supported by support devices (not shown) that support both sides thereof. Further, in the vicinity of the substrate 7, a component supply device 9 is arranged to sequentially supply components 8 such as electronic components, for example.

When inserting a component 8 onto the board 7, the component 8 of the component supply device 9 is gripped by the chuck 4 of the component insertion device 1 and transported by operating the arm 2 to a predetermined position on the board 7. However, the parts on the board 7 are mounted through holes (not shown).
Insert the conductive leg of part 8 into. At the same time, the moving table 5 is operated to move the clinch device 6 to the above-mentioned substrate 7.
is moved below a predetermined position to detect the conductive leg of the component 8 and perform bending or cutting operations.

By the way, the above-mentioned conventional component mounting device has the disadvantage that the component insertion device 1 becomes large because the rotary head 3 installed at the tip of the arm 2 of the component insertion device 1 holds a large number of chucks 4. Therefore, the component insertion device 1 must be installed taking into account the operating range of the arm 2, resulting in a problem that the space factor is very poor. Also,
Since the component insertion device 1 and the movable table 5 provided with a plurality of clinching devices 6 are driven separately, there is also the problem that their control becomes extremely complicated.

Therefore, in order to solve these difficulties, a system as shown in FIG. 4 has been developed.

In the same figure, reference numeral 11 indicates a two-axis orthogonal component insertion device, and this component insertion device 11 includes an arm 12 that reciprocates in the direction of arrow X, and a moving table 13 that reciprocates in the direction of arrow Y. There is a slight difference between Furthermore, an insertion head 14 having an attachment/detachment mechanism is attached to the tip of the arm 12. A substrate 15 is disposed below the insertion head 14 and supported on both sides by a support device (not shown). Further, a clinch rod 16 is arranged at a predetermined position below the substrate 15. Furthermore, this substrate 15
A component supply device 17 is disposed near the component supply device 17, and a plurality of various types of components 18 and a plurality of chucks 19 corresponding to the shapes of these components 18 are arranged in the component supply device 17. Further, these chucks 19 are detachably supported by the above-mentioned insertion head 14.

When attaching the component 18 to the substrate 15, the arm 12 and the moving table 13 are operated to make the insertion head 14 support a predetermined chuck 19.
9 to grip a predetermined part 18. Then, the insertion head 14 is moved to a predetermined position on the board 15, and the chuck 19 is lowered to insert the conductive leg of the component 18 into the component mounting hole of the board 15, as shown in FIG. Then, the conductive legs are bent by the clinch rod 16 and the component 15 is attached.

However, in this conventional component mounting device, a detection device for detecting the conductive leg of the mounted component 18 is omitted, so there is a drawback in that it lacks reliability. Because of the bending, it was impossible to install parts that required cutting the conductive legs.

Therefore, the configuration may be such that a clinch device having the function of detecting the conductive leg shown in FIG. 3 is arranged, but in that case, the component insertion device 1
A problem arises in that the control of the clinch device becomes complicated.

(Problems to be solved by the invention) As mentioned above, with the horizontally articulated component mounting device, it is not possible to reduce the space, and it is difficult to control the component insertion device and the clinch device. .

Furthermore, the two-axis orthogonal component mounting device lacks reliability in mounting components, and it is impossible to mount components that require bending the conductive legs of the component. Furthermore, when a clinch device is used, it is very difficult to control the component insertion device and the clinch device.
