Description

[Detailed description of the invention] [Industrial application field] This invention is an electronic component insertion device that moves and positions a printed circuit board in the x-axis direction and moves and positions a base machine to which an insertion head body is attached in the y-axis direction. This invention relates to a clamping device for an insertion head main body.

[Conventional technology]

In electronic component insertion equipment, the printed circuit board is generally set on an XY table, and the
Electronic components were inserted into the printed circuit board by moving the XY table in the axial direction and lowering the insertion head of the insertion device above the printed circuit board. The position of the insertion head was fixed.

[Problem to be solved]

Conventional machines using XY tables had slow insertion speeds and were unable to handle a wide variety of parts. Furthermore, it is not possible to change the main body of the insertion head depending on the type of parts; at most, the chuck of the insertion head can only be changed, and it is not possible to continuously insert more irregularly shaped parts.

SUMMARY OF THE INVENTION An object of the present invention is to provide a clamping device for an insertion head body in an electronic component insertion device, which allows the insertion head body to be replaced depending on the type of component to be inserted.

[Means for solving problems]

In order to achieve the above-mentioned object, this invention provides an electronic component insertion device for moving and positioning a printed circuit board in the x-axis direction and moving and positioning a base machine to which the insertion head body is attached in the y-axis direction. This is a clamping device that has a rail groove formed on the upper part of the base machine, and an H that slides into the rail groove and fits in the lower part of the insertion head main body.
The drive source is a single swingable cylinder that forms a letter-shaped rail, operates when the front end of the rail comes into contact with the front end of the base machine, locks the front end of the rail, and presses the rail downward. A stopper claw is provided at the rear end of the rail, and an inclined part is formed at the rear end of the rail in a direction that allows the pressing claw, which will be described later, to distribute the pressing load into the load that presses against the stopper claw and the load that presses the rail downward. A pressing claw is provided at the rear end of the machine, the driving source of which is a single swingable cylinder that can press against the slope of the rail.

[Effect]

In this invention, the rail of the insertion head main body is inserted into the rail groove on the upper part of the base machine, and the front end of this rail hits the stopper claw provided on the base machine, and the rear end of the rail is pressed by the pressing claw, and the stopper claw is pressed. It locks onto the front end of the rail and presses the rail downward. This reliably positions the insertion head body and brings the insertion head to the proper position.

〔Example〕

Preferred embodiments of this invention will be described below with reference to the drawings.

In FIG. 1, an insertion head body 3 having an insertion head 1 and a clinch head 2 located axially opposite to the insertion head 1 is removably attached to the upper part of a base machine 4. As shown in FIG. The insertion head 1 is adapted to swing in the direction of the arrow by means of a cylinder 5. The base machine 4 is adapted to slide on a slide rail 6, a threaded rod 7 is screwed into the base machine 4, and the base machine 4 is adapted to be moved in the axial direction of the threaded rod 7 by rotation of the threaded rod 7. Further, a guide bar 8 is inserted through the base machine 4, so that the base machine 4 can be moved stably. Further, a stopper pawl 9 is provided at the front end of the base machine 4, and a pressing pawl 10 is provided at the rear end of the base machine 4. The stopper pawl 9 is operated by links 11, 12,
13 is performed by actuating a cylinder 14. The pressing claw 10 is also actuated by the actuation of a cylinder 16 via a link 15.

An H-shaped rail 17 is formed on the lower surface of the insertion head body 3, and a rail groove 18 (see FIG. 9) is formed on the upper part of the base machine 4.
The lower projecting portion 17A of the rail 17 fits into such a rail groove 18. The rear end side of the overhanging portion 17A of the rail 17 is formed into an inclined portion 17B. Details of the rail 17 are as shown in FIGS. 2 and 4.

The pressing pawl 10 that presses the inclined portion 17B at the rear end of the protruding portion 17A on the lower surface of the rail 17 is formed as shown in FIG. 5, and its link configuration is shown in FIGS. 6 and 7.
It is configured as shown in the figure. That is, the movement of the pressing claw 10 is restrained by the links 15, 15a and the cylinder rod 16A of the cylinder 16, and the operation of the cylinder 16 causes the pressing claw 10 to rotate about its fulcrum x. When the cylinder rod 16A is retracted, the right end side of the link 15 in FIG. 5 rotates downward, resulting in the state shown in FIG.
Release the pressure against. On the other hand, when the cylinder rod 16A is extended, the link 15 rotates counterclockwise and becomes the state shown in FIG. 7, that is, FIG. 5.
The pressing claw 10 presses the rear end side of the rail 17.

The stopper pawl 9 is designed to engage with the distal end side of the rail 17 and press it downward, as shown in FIGS. 8 and 9.
is composed of links 11, 12, 130, 13 and a cylinder rod 14a, and as the cylinder 14 expands and contracts, the links 11 and 12 rotate around their fulcrums x and z, and as a result, the stopper claw 9 is approximately parallel to the vertical direction. Make a move. This allows cylinder 1
When the cylinder 4 is retracted, the state shown in FIG. 8 occurs, and the stopper claw 9 presses the tip 17A of the rail 17 downward. Conversely, when the cylinder 14 is extended, the state shown in FIG. 9 occurs, and the stopper claw 9 9 moves upward and the pressure on the seal 17 is released.

Note that when the front end of the rail 17 comes into contact with the stopper pawl 9, means is provided to sense this and actuate the cylinders 14 and 16, or the actuation is performed by an external signal.

10 and 11 show the rail grooves 18 formed in the upper part of the base machine 4, respectively.

The entire electronic component insertion device using the above-mentioned clamp device is constructed as shown in FIG. 12.
That is, a printed circuit board transport mechanism 22 configured to be able to move the printed circuit board 21 in the x-axis direction is provided between a pair of rails 19 and 20 whose interval can be adjusted, and the printed circuit board transport mechanism 22 is inserted in parallel on the rear side of this printed circuit board transport mechanism 22. A large number of head main bodies 3 are provided. A number of component feeders 23 corresponding to the number of insertion head bodies 3 are set on the rear side of the insertion head body 3.
This parts feeder 23 is fixed to a guide bar 8 shown in FIG. Then, the insertion head 1 oscillated by the cylinder 5 grabs the component supplied from the component feeder 23, and the insertion head 1 returns to the vertical line again and descends to insert the component into a predetermined position on the printed circuit board 21. It's getting old.

〔effect〕

As explained above, according to this invention, a rail groove is formed in the upper part of the base machine, and an H
Form a letter-shaped rail and attach it to the front end of the base machine.
A stopper claw is provided at the rear end of the rail, which operates when the front end of the rail comes into contact with it, has a single swingable cylinder as a drive source, and is capable of locking the front end of the rail and pressing the rail downward. An inclined part is formed in a direction that enables the pressing claw to distribute the pressing load into the load pushing against the stopper claw and the load pushing down the rail. Since the pressing claw is driven by a single swingable cylinder that can press the insertion head, it is easy to attach and detach the insertion head body, and it can handle a wide variety of parts, making it possible to continuously insert more irregularly shaped parts. It becomes possible to insert the Furthermore, since the clamping device is as described above, the insertion head main body can always be positioned at an appropriate position, and the insertion head can be placed in the correct position.
