Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of mounting components in an automatic insertion machine that automatically mounts radial components, and particularly relates to a method of mounting radial components that are mounted with a height. .

Conventional technology The automatic mounting of radial components onto a printed circuit board using an automatic insertion machine consists of 1) positioning and holding the printed circuit board on the workbench, and 11) inserting the lead of the radial component supplied from the parts feeder into the lead insertion hole of the printed circuit board. Guide to, 11
The steps are as follows: 1) Inserting the lead into the lead insertion hole by pushing the component with a pusher, and 1v) Temporarily fixing the component by caulking the lead protruding from the back of the printed circuit board.

These radial components include those formed by having a pair of leads extending in one direction with respect to the component body, such as a disk, a square plate type capacitor, and a one-way lead type tubular type capacitor. This type of component is mounted on a printed circuit board with a certain level of height.

Even for parts with leads extending in both directions from a substantially cylindrical part body, the part body may be mounted perpendicularly to a printed circuit board. In this case as well, like the parts having the above-mentioned shapes, they are mounted on the printed circuit board with a certain level of height.

Problems to be Solved by the Invention However, radial components that are mounted to a certain height are unstable when temporarily fixed by automatic mounting. For this reason, if the parts are not reliably temporarily fixed by caulking the leads, they will tilt to one side with the line connecting the pair of leads as a boundary.

If this part of the component occurs on the mounting position side of another component that is mounted in close proximity, and if it is placed in the mounting operation path of the other component, it will become an obstacle to the mounting operation. This causes problems such as component insertion errors and component damage due to contact.

In addition, since the component is mounted with a certain height, the space for mounting other components to be mounted close to each other is narrowed. Therefore, it is necessary to increase the mounting density of components to such an extent that it does not interfere with the automatic mounting operation of adjacent components.

The present invention has been made in view of the above points, and an object of the present invention is to provide a component mounting method that eliminates the problem of radial components that are mounted at a high height.

In order to achieve an object more than just a means to solve the problem, the present invention provides a workbench for holding a printed circuit board as a bridge, and a lead insertion hole of the printed circuit board positioned and held on this workbench. a guide means for guiding the leads of the radial component to be inserted; a pusher for pushing the radial component guided by the guide means from above and inserting the lead into the lead insertion hole; and a pusher for inserting the lead into the lead insertion hole; A method for mounting a component in an automatic insertion machine for automatically mounting a radial component onto a printed circuit board, the method comprising: a lead crimping means for temporarily fixing the component; By simultaneously moving the pusher in a direction to push the component downward and in a predetermined horizontal direction, the tip of the pusher moves in a substantially arcuate trajectory to push down the component in a predetermined direction; The feature is that the lead of the component is bent.

According to the present invention described above, the pusher for pushing the component is moved in a substantially arcuate trajectory in the direction of pushing the component downward and in a predetermined horizontal direction at the same time, thereby pushing the component in advance. Implementation is done by pushing down.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an automatic insertion device according to the present invention.
0 indicates a printed circuit board, and 11 indicates a radial component.

The radial components 11 are intended for components that are mounted with a certain height, such as unidirectional lead type components such as disk and square plate capacitors. Note that this also includes cases where the component body is mounted vertically even in the case of a double-lead type component.

The automatic loading device includes a workbench 12 that bridges a printed circuit board 10 to position and hold it, and a parts 11 that is located above the printed circuit board 10 held on the workbench 10 and is supplied from a parts feeder (not shown). and insert the leads 111.1.11 of the component 11 into the lead insertion holes 101.1.1 of the printed circuit board 10. ．． guide means 13 for guiding the component 11 to a position corresponding to the lead 111 . a pusher 14 for inserting the LH into the lead insertion hole 101.1;
It is located below the printed circuit board 10 held on the workbench 10, and is pushed by the pusher 14 so that the printed circuit board 1

The component guide means 18, the pusher 14, and the lead crimping means 15 are provided to be movable vertically and horizontally, respectively, and are used to automatically mount the component 11 on the printed circuit board 10. is omitted. The mounting of the components 11 onto the printed circuit board 10 is controlled by numerical control means and is performed sequentially.

Next, a procedure for automatically mounting components using the automatic insertion machine according to the present invention will be described.

The mounting of the component 11 on the printed circuit board 10 is generally performed in the following steps.

1) Position and hold the printed circuit board 10 on the work table 12 (work position).

11) The leads 11], 111 of the parts 11 supplied from the parts feeder are made to correspond to the lead insertion holes 101, 101 of the printed circuit board 10.

111) Push down the component 11 with the pusher 14 and insert the leads 111, 111 into the lead insertion holes 101, 10.
Insert it into 1.

1. Caulk 111 to temporarily fix component 11.

■) Then, push down the parts.

This pushing down operation of the component is performed as shown in FIG.

The solid line in FIG. 2 shows the state in which the component 11 is temporarily fixed. At this time, the pusher 14 remains in contact with the component 11.

In this state, a direction a in which the pusher 14 is moved downward;
It is simultaneously moved in a predetermined horizontal direction a2. Therefore, while the tip of the pusher 14 is in contact with the component 11,
It is moved so as to draw a substantially arc-shaped trajectory A that rotates around the end of the printed circuit board 10 side as a fulcrum.

Then, the pusher 14 moves to the position indicated by the two-dot chain line in FIG. By this movement of the pusher 14, the leads 111.degree. 111 of the component 11 are bent, and the component 11 is pushed down in a predetermined direction as shown by the two-dot chain line in FIG.

The pushing angle of the component 11 can be easily set by setting the movement stroke of the pusher 14 in the movement direction al+82.

Note that the direction in which the component 11 is pushed down is the lead 1 of the component 11.
11 and 111, either left or right, and in the opposite direction to the mounting position of the next automatically mounted component. In FIG. 2, the left side of the drawing is a mounting space for other components to be mounted close to the component 11.

Next, FIG. 3 shows an example in which parts 11, 11, . . . are successively mounted in one direction in close proximity, and shows the movement path of the pusher 14 during the mounting operation.

In Fig. 8, the moving path of the pusher 14 is indicated by a downward motion for pushing the part 11, a circular motion for pushing the part 11, an upward movement to the horizontal movement position, and a symbol for the next order. The horizontal movement of the component 11 to the pushed-in position is shown.

In this way, when the parts 11, 11.11 are successively mounted, the pusher 14 is sequentially moved along the path of ■■■■. Therefore, the component 11 is pushed down in the opposite direction (to the left in the drawing) with respect to the component mounting direction (from right to left in the drawing). In this case, the space in which the component 11 is mounted becomes much larger than the space in which the component 11 is mounted vertically. Therefore, automatic mounting of components can be performed extremely easily, and the mounting density of components can be increased.

However, since the parts are pushed down in advance in a predetermined direction, the problem of the parts being tilted in an undesired direction is eliminated. As a result, the automatic mounting problems and problems caused by the tilting of the component due to defects in the temporarily fixed state of the component are eliminated.

As described in detail, according to the component mounting method of the present invention,
Since components to be mounted at a high height are pushed down in advance, obstacles to automatic mounting of other components mounted in close proximity are eliminated, and reliable automatic mounting operations can be performed.
