Description

[Detailed description of the invention] The present invention relates to a device for inserting grommets into a printed wiring board used as part of an electronic circuit, and is capable of continuously and automatically inserting the grommets into the printed wiring board. The purpose is to provide an insertion device.

The present invention will be described in detail below with reference to the drawings showing one embodiment thereof.

FIG. 1 shows the overall appearance of the insertion device, where:
1 is the eyelet to be supplied, 2 is the stocker that stores a large number of eyelets 1, and 3 is the eyelet 1.
4 is a direction changing device which separates the eyelets 1 one by one from the shooter 3, takes them out, changes the direction by 90 degrees and supplies them downward; 5
8 is an insertion device for taking out the eyelet 1 from the bottom surface of the direction changing device 4, changing the direction by 180 degrees, carrying it to the position of the mounting hole 7 of the printed circuit board 6 to be attached, and inserting it by moving it up and down; 8 is the eyelet 1; It is an anvil that is caulked with the bottom surface.

Moreover, FIGS. 2 and 3 are a sectional front view and a sectional side view mainly showing the direction changing device 4 in the device, and 9 is a rotary plate for taking out the eyelet 1 and changing the direction; 11 is its drive shaft, 11 is its bearing, 12 is a crankshaft, 13 is a drive connecting rod, and 14 is a swinging rod. The other end of this swinging rod 14 is connected to the insertion device 5, and is driven by its vertical movement. be done. Reference numeral 15 denotes an intake pipe that takes in air from the eyelet storage hole 16 of the rotary plate 9. Furthermore, 17 is a table to which this is attached.

4, 5 and 6 are diagrams showing the relationship between the direction changing device 4 and the insertion device 5. Next, the operations of these devices will be described in order.

First, the eyelets 1 are arranged in a line by the parts stocker 2, laid down in the same direction, placed sideways on an inclined shooter 3, and slid or rotated inside the shooter 3 due to their own weight. It descends and is carried to the rotating plate 9 of the direction changing device 4. In the rotary plate 9, there is only one stopper 1 at the tip of the storage hole 16 through which air is taken in by the intake pipe 15, and the small diameter portion of the stopper 1 is fitted into the storage hole 16, and the brim portion is connected to the storage hole 16. The eyelet 1 is housed so as to protrude outward, and the lower end of the housing hole 16 communicating with the intake pipe 15 is closed by the small diameter portion of the eyelet 1, so that the eyelet 1 is attracted and held. The rotary plate 9 is then turned downward by 90° and the eyelet 1 is delivered to the insertion device 5. Here, the rotating plate 9 is rotationally driven in accordance with the swinging motion of the swinging rod 14 which moves in accordance with the vertical movement of the insertion device 5. When the insertion device 5 descends and the swinging rod 14 swings in the direction of arrow A, the connecting rod 13 and the crankshaft 1
2 and the shaft 10, the rotating plate 9 rotates in the direction of arrow C as shown in FIG. 4, and is stopped by the stopper 18 at the position shown in FIG. Rotating plate 9
After the eyelet 1 has stopped, the small diameter part of the eyelet 1 enters the tip of the storage hole 16, which is sucked in by the intake pipe 15 connected to the vacuum exhaust source, as described above, and the eyelet 1 is vacuum-adsorbed one by one. It is taken out from the shooter 3 and held on the rotary plate 9.

Next, as shown in FIG.
When the rotating plate 9 swings in the direction of arrow B, the rotating plate 9 rotates 90 degrees in the direction of arrow D and is stopped by the stopper 18 at the position shown in FIG. In other words, the direction of the eyelet 1 has been changed so that the brim portion faces downward. After the stop, the eyelet 1 held by the rotary plate 9 by vacuum suction is moved to the insertion arm 19 of the insertion device 5, which is moving upward at that time, as the suction operation for vacuum suction is stopped. handed over to. At this time, the eyelet 1 remaining in the shooter 3 is held within the shooter 3 with the rotary plate 9 serving as a stopper.

The insertion arm 19 holding the eyelet 1 moves slightly downward according to its insertion device mechanism, and then turns 180° in the direction of arrow F as shown in FIG. The small diameter portion of the stopper 1 is inserted into the mounting hole 7 of the printed circuit board 6 at the lowest point as shown in FIG. 4. At this time, the anvil 8 backs up the printed circuit board 6 and caulks the eyelet 1, fixing the eyelet 1 to the printed circuit board 6, and detects electrical continuity with the insertion arm 19, thereby fixing the eyelet 1. Determine whether the insertion state is good or bad.

By repeating the above operations, the eyelet 1 is separated and held from the shutter 3 by vacuum suction and the function of the rotary plate 9, and parts like eyelet 1 that are difficult to separate and hold can be removed. They can be automatically attached to the attachment holes 7 of the printed circuit board 6 one after another.
Further, the eyelet 1 remaining in the shooter 3 is held within the shooter 3 with the rotary plate 9 serving as a stopper.

As explained above, according to the present invention, it is possible to orderly and accurately feed grommets that have a flange portion and are difficult to feed by using a shutter and lay them out sideways, and also to In the conversion device, when the rotary plate comes to the first position where the stopper is supplied from the shooter, the stopper function of the rotary plate disappears and the small diameter part of the stopper is moved to be stored in the storage hole provided in the rotary plate. By sucking air into the storage hole and adsorbing the small diameter part of the eyelet, it is possible to easily hold the eyelet that is difficult to hold and change the direction of the sideways eyelet downward. The rotating plate acts as a stopper to hold the stopper in the shutter, and there is no need to provide a new stopper, and when the rotating plate comes to the first position, the stopper function disappears. The eyelet can be immediately supplied into the storage hole of the rotating plate. Furthermore, the insertion device is configured to receive this eyelet, rotate, and insert downward, making insertion work extremely easy.
It is possible to efficiently and automatically insert a large number of eyelets in a short time using a device with a simple configuration.
