Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a component conveyance device 1 for conveying small components such as ICs (semiconductor integrated circuits) to a predetermined position along a guide groove of a shooter.

As shown in FIGS. 1 and 2, a conventional component conveying device of this type includes a chute (1) formed with a guide groove 0ω for sliding a component (7) to be conveyed in the longitudinal direction, and a side surface of the chute. The separation mechanism (not shown) is inserted into the
A plurality of first to eighth stoppers (2
) (a) (4). Then, the first stopper (2) is connected to the adjacent second stopper (
3) The parts (
7) and allow it to fall naturally from the end of the chute (1) at a predetermined time due to its own weight. This is provided to detect that the parts (7) have been stopped and stop the continuously fed parts (7).Furthermore, at a predetermined position of the guide groove (1a) of the chute (1), there is a , as shown in Fig. 2, "Paris J (
A separating inclined surface (lb) is formed to prevent the adjacent parts L7) (7) from becoming separated due to strong engagement between the parts L7) and (7c).

In conventional parts conveying devices, adjacent parts (7) (
7), but in order to prevent them from becoming separated from each other due to their firm engagement, the separation slope (1ω) is formed. A sufficient separation effect cannot be expected, and adjacent parts (7
) In (7), even if the second stopper (3) is released because the Paris J (7b) and (7c) are firmly engaged with each other, the part (7) will not close to the next first stopper (2). There was a drawback that it was not sent out towards.

This invention was made with attention to this point, and even if adjacent parts do not separate from each other due to their respective "pars" being firmly engaged, one part can be moved by the feed claw drive device: The object of the present invention is to provide a component conveying device in which a component can be forcibly separated from the other component by a feed claw operated by a device and then sent to the first stopper of the next stage. 1 and 2 show one embodiment of the present invention, however, since the same reference numerals as those in the above-mentioned conventional device (FIGS. 1 and 2) refer to the same constituent members, the explanation thereof will be omitted.

First, in Fig. 8, (6) is a feed pawl drive device that incorporates a pair of horizontal rectangular movement mechanisms (6a) and (6b), one of which has a built-in horizontal rectangular movement mechanism (6a). A feed claw (5A) consisting of a sharp comb-like claw piece (5a) inserted between a plurality of protruding leads (7a) and a claw piece (5b) that engages with the front edge of the component (7). is installed and also others.

The rear edge of the component (7) (
A feed pawl (5 wheels) having a pawl piece (5c) that engages with the feed pawl (6A) (5Bl) is attached, and each of the feed pawls (6A) (5Bl) is horizontally moved by the feed pawl drive device (6) as shown in FIG. Part (7) that performs a rectangular movement and is stopped at a predetermined position on the shooter (1) by the second stopper (3).
This is provided to forcibly convey the material to the position of the first stopper (2) of the next stage.

Since the component conveying device of the present invention is configured as described above, first the components (7) continuously fed through the guide groove (1a) of the chute (11) are transferred to the second stopper (3).
At the same time, the following part (7) is stopped by the eighth stopper (4), and then the feed claw drive device (6)
When the claw piece (5a) of the feed claw ω~ is inserted between the leads (7a) of the component (7) by operating, the claw piece (5b) also engages the front R (7d)tL of the component (7) at the same time. At the same time, move the claw piece (5c) of the feed claw (5Bl) to the trailing edge (7e) of the part (7).
).

Next, after the first stopper (2) and the second stopper (3) are released, the component (7) is engaged with the first stopper (2) of the next stage by the horizontal rectangular movement of the feed pawl drive device (6). At this time, the claw piece (5b) collides with the preceding part (7), which was previously stopped by the first stopper (2), and pushes it out. Needless to say, it is allowed to fall naturally from the end of +11 due to its own weight. In addition, the pair of feed claws (5A) driven by the feed claw drive device (6) takes 0 seconds to release the component (7).
) to the position of the first stopper (2) in the next stage, the two feed claws (5A) ω are moved at appropriate timing with each of the first to eighth stoppers (2), (3), and (4). It goes without saying that the part (7) is forcibly conveyed without any difficulty because the part (7) is moved while the part (7) is moved to the position of the first stopper (2) of the next stage. After the feeding claw (5A) (58) has been conveyed up to this point, the feeding claw (5A) (58) automatically returns to the original position shown in No. 8IA by the horizontal outer movement of the feeding claw driving device (6), thus completing one cycle.

As described above, according to the present invention, the feed claw drive device (
After one part (7) is forcibly separated from the other part by the feed claw ωA) (5B) operated by 6), it is sent to the first stopper of the next stage, so it is not possible to separate the adjacent parts as before. This has the excellent effect of ensuring that the parts (7) to be transported are always smoothly conveyed on the chute +1) without being separated from each other due to the strong engagement of their "paris". It is something that you have. Also, the claw piece (5) of one feed claw (5A)
If a) is formed into an a-tooth shape, any of the claw pieces ωω will engage with the lead (7a) of the component (7), so that the part can be reliably captured by the claw piece (5a). In addition, after one part (7) is forcibly separated by the claw piece (5a), as shown in FIG. Press the nail piece (5
If c) is configured to suppress the trailing edge (7e) of the component (7), the component (7) will have a gap between the lead (7a) of the component and one of the claw pieces (5a). This also has the effect of preventing unreasonable conveyance and preventing feeding errors.

Note that the above-mentioned embodiment is a single in-line package (generally called SIL) such as an IC.
However, it goes without saying that the present invention is not limited to this, and can also be used in a dual in-line package (generally referred to as DILk).
