Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic component delivery device. More specifically, the present invention relates to a device for feeding out electronic components from a magazine.

[Prior Art] Component supply to an electronic component mounting device, which automatically attaches electronic components such as ICs to printed circuit boards, is generally carried out by feeding out electronic components from a plastic magazine as shown in Fig. 2. However, in recent years, as various high-performance electronic component mounting devices have been developed, there has been a demand for the development of even higher-performance component delivery devices.

In other words, a typical example of a conventional electronic component delivery device is a magazine storage box replaceable type disclosed in Japanese Patent Publication No. 52-21231. A magazine storage box is loaded into the magazine stocker attached to the device, and then, when parts are sent out from all magazine groups in this box,
This box (the box loaded with the group of empty magazines) is removed from the magazine stocker, and another previously prepared box is loaded into the magazine stocker.

[Problems to be Solved by the Invention] For this reason, there is a drawback that when replacing the box described above, parts delivery is interrupted and continuous delivery is difficult. Even though they tried, they could not get it to work properly.

[Problems to be Solved by the Invention] The present invention was invented focusing on the above-mentioned problems, and its purpose is to solve the problem of empty magazines after electronic components have been sent out. Automatically switches between the cassette body holding the group of electronic components and the cassette body holding the magazine group that is sent out after storing electronic components, without interrupting component delivery. The object of the present invention is to obtain an electronic component delivery device that can perform continuous delivery.

[Means for Solving the Problems] An electronic component delivery device according to the present invention that achieves this object is configured such that both ends of the magazine housing electronic components on the component loading/unloading side protrude outward. a cassette body stacked in multiple stages and held in a magazine holder; an upper rail and a lower rail having concave cross-sections and arranged at regular intervals with protrusions facing each other; and the parts of the magazine. wheels mounted on the magazine holder so that the cassette body can be guided by the protrusions of the rails and run by itself when both end portions on the loading/unloading side are inserted into the grooves of the rails; a component transfer rail having one end guided to a component delivery port opened in the groove bottom of the rail; a component transfer guide fixed to the one end of the component transfer rail and protruding into the groove of the lower rail; a magazine stopper positioned below the component delivery guide and fixed to the bottom of the groove of the lower rail so that its upper end is connected to the lower end of the component delivery port; the component transfer guide and the magazine stopper; a component detection device that detects an electronic component sent out from the magazine that is in contact with and is locked onto the component transfer rail via the component delivery guide; a pusher device that causes a pusher to protrude between the parts transfer guide and the magazine stopper when passing through the parts transfer guide and the magazine stopper, and slides the empty magazine toward the upper rail to separate it from the parts transfer guide and the magazine stopper; a regulating guide disposed at a constant interval from the component transfer rail to prevent the electronic component sent onto the component transfer rail from coming off the rail when sliding to another location; and a slide of the empty magazine. The magazine is characterized by comprising a magazine slide prevention stopper fixed to the bottom of the groove of the upper rail so as to prevent other magazines from cooperating with each other when the magazine slides.

[Example] Hereinafter, an example will be described based on the drawings. In FIG. 1, 1 indicates an upper rail, and 2 indicates a lower rail, and both rails 1 and 2 are composed of members with a concave cross section. The protrusions 3 are inclined and arranged at regular intervals so as to face each other. Although not shown, both rails 1 and 2
is mounted to the apparatus frame via suitable rail support means and arranged as described above.

Next, reference numeral 4 indicates a cassette body, which is shown loaded on both rails 1 and 2 in the figure, but the cassette body 4 is a plastic magazine 5 shown in FIG. The 10 magazines are stacked in multiple stages and held in a magazine holder 7 with both ends of each magazine 5 on the component loading/unloading side (one end 6a and 6b of the component loading/unloading side shown in FIG. 2) protruding outward. There is.

Incidentally, as shown in FIG. 3, which is a longitudinal cross-sectional view of FIG. It is constructed by fixing an elastic body 11 to the lower frame member 9, and the magazines 5 stacked in multiple stages on the lower frame member 9 are pressed downward by the elastic body 11.

Next, 12 indicates a wheel, and the wheel 12 is rotatably mounted on the upper frame member 8 and the lower frame member 9 of the magazine holder 7. For this reason, the cassette body 4 is
When loaded onto both rails 1 and 2, the cassette body 4
is guided by the protrusions 3 of both rails 1 and 2 and can self-propel downward. The loading of the cassette body 4 onto both rails 1 and 2 is carried out by bringing the wheels 12 into contact with the protrusions 3 of both rails 1 and 2, and by pressing both ends of the magazine 5 on the parts loading/unloading side which are projected outward from the magazine holder 7. (One side 6a and 6b on the parts loading/unloading side shown in FIG. 2) are connected to both rails 1,
This is done by inserting it into the groove 13 of No. 2.

Incidentally, as shown in FIG. 3, the magazine 5 inserted into the groove 13 of both rails 1 and 2
Both ends of the component loading/unloading side are in light contact with the side surfaces of the protrusion 3, and as shown in FIG. A large gap is formed between the other end 6b on the component loading/unloading side and the groove bottom 14 of the upper rail 1. Therefore, the cassette body 4 loaded on both rails 1 and 2 can easily move on its own.

Next, reference numeral 15 indicates a component transfer rail, and this rail 15 is made of a member having a rectangular cross section, and is fixed to the upper end of an L-shaped bracket 17 fixed to the side bracket 16. It is guided to a rectangular component delivery port 18 (see FIG. 4) opened in the groove bottom 14 of the rail 2. Further, a component transfer guide 19 having a rectangular cross section is fixed to the one end of the component transfer rail 15 mounted in this manner and protrudes into the groove 13 of the lower rail 2.

Therefore, the lowermost magazine 5 of the cassette body 4 loaded on both rails 1 and 2 and self-propelled downward comes into contact with the parts transfer guide 19, that is, the recess 20 of the magazine 5 (see Fig. 2). comes into contact with this guide 19. At the same time, the groove bottom 14 of the lower rail 2 is positioned below the component transfer guide 19.
The lower end 22 (see FIG. 2) of the magazine 4 comes into contact with a magazine stopper 21 fixed to the magazine. This figure is shown enlarged in FIG.

Thus, the magazine 5 at the lowest stage is locked by the component transfer guide 19 and the magazine stopper 21, and the cassette body 4 is kept stationary. Then, magazine 5
A predetermined number of DIP type electronic components 2 housed inside
3 are sent out in a continuous manner to the component transfer rail 15 via the component transfer guide 19. The DIP type electronic components 23 are packed into the magazine 5 group of the cassette body 4 in the previous process, and the cassette body 4 is loaded onto both rails 1 and 2 by an operator.

Next, the DIP that has been sent out from the magazine 5 of the cassette body 4 onto the component transfer rail 15 as described above is
The type electronic component 23 slides on the component transfer rail 15 and is transported to another location. At this time, the electronic component 23 is moved upward by a regulation guide 24 fixed to the side bracket 16 at a constant interval from the component transfer rail 15. This prevents it from coming off the component transfer rail 15. Note that the side bracket 16 is fixed to the lower rail 2.

Next, 25 indicates a pusher device, and this device 25 includes an air cylinder 26 fixed to the side bracket 16 via a suitable bracket;
It consists of a pusher 27 fixed to the tip of the rod of the cylinder 26 and a pusher guide 28 fixed to the lower rail 2.

Further, 29 indicates a component detection device, and this device 2
Reference numeral 9 is composed of a light projector 30 and a light receiver 31 fixed to the side bracket 16 via a suitable bracket, and the light projector 30 has a hole (not shown) penetrated by the regulation guide 24 and the component transfer rail 15. The light is emitted so as to pass through and reach the light receiver 31.

For this reason, the lowest magazine 5, which is locked by the parts transfer guide 19 and the magazine stopper 21,
was first sent out onto the parts transfer rail 15 from
The light is blocked by the DIP type electronic component 23, and when the DIP type electronic component 23 sent out last passes the light projection point, the light shielding is released. Then, the air cylinder 26 is activated based on this signal.
The rod is projected and the pusher 27 is projected into the groove 13 from the back side of the lower rail 2.

The upper end of the pusher guide 28, the lower end of the component transfer port 18, and the upper end (magazine locking surface) of the magazine stopper 21 are positioned so as to be connected to each other to form a flat surface, and are arranged so as to form a flat surface. The guide 19 and magazine stopper 21 protrude from the groove bottom 14 of the lower rail 2 at equal lengths.

Therefore, the tip of the pusher 27, which is guided by the upper end of the pusher guide 28 and projected into the groove 13 of the lower rail 2, comes into contact with the lower end of the one end 6a on the parts loading/unloading side of the lowest magazine 5 (empty magazine). and push this empty magazine to slide it toward the upper rail 1. That is, the pusher 27 is
Since the width dimension of this is approximately equal to the width dimension L of the pusher guide 28 (see Fig. 4), there are two points at the lower end of one end 6a of the component loading/unloading side of the lowest magazine 5 (empty magazine). and slide it to a position where one end 6b of the lowermost magazine 5 (empty magazine) on the parts loading/unloading side forms a small gap with the groove bottom 14 of the upper rail 1.

Then, one end 6a of the component loading/unloading side of the lowest magazine 5 (empty magazine) is connected to the component transfer guide 19.
Then, the cassette body 4, which was detached from the magazine stopper 21 and was stationary, moves downward by itself,
Then, when the magazine 5 in the second stage from the bottom comes into contact with the component transfer guide 19 and the magazine stopper 21 and is locked, it is stopped again.

Thereafter, similarly, the electronic components 23 can be sent out sequentially from the lower magazine 5 to the upper magazine 5. In addition, the pusher 27 is attached to the lower rail 2.
After being projected into the groove 13 in a predetermined position, it is sunk into the original position. Further, one end 6a of the empty magazine 5 on the component loading/unloading side, which has been separated from the component transfer guide 19 and the magazine stopper 21 and moved downward, forms a small gap with the magazine stopper 21.

Next, reference numeral 32 denotes a magazine slide prevention stopper. This stopper 32 is made of a flat plate of a certain length, and is fixed to the groove bottom 14 of the upper rail 1. In other words, its lower end is connected to the component transfer guide 19 and the magazine stopper 2. It is located slightly above the magazine 5 that is locked in contact with the magazine 5, and is fixed so as to form a small gap with one end 6b on the component loading/unloading side of the magazine group in multiple stages on the locked magazine 5. There is.

For this reason, when the locked magazine 5 (empty magazine) is pushed by the pusher 27 and slid toward the upper rail 1, this magazine 5 (empty magazine) is moved along with the magazines 5 of the other stages. (Magazine group in which electronic components 23 are housed) is prevented from sliding.

It should be noted that the magazine stopper 21 is also made of a flat plate of a certain length, similar to the magazine slide prevention stopper 32, so that the magazine 5 housing the electronic components 23 is in contact with the component transfer guide 19 and the magazine stopper 21. Due to the impact of contact,
An empty magazine 5 that has been slid toward the upper rail 1 is prevented from being moved toward the lower rail 2. That is, since the magazines 5 other than the bottom and top tiers have their slippery plastic surfaces in contact with each other, if they are held in the magazine holder 7 while being slid toward the upper rail 1, the impact However, this can be prevented by the magazine stopper 21.

Therefore, the cassette body 4 holding the 5 groups of empty magazines can be sent downward with the one end 6a on the component loading/unloading side aligned so as not to form unevenness.
After removing this cassette body 4 from the lower ends of both rails 1 and 2, electronic components 2 are placed in each magazine 5.
3 and can be reloaded from the upper ends of both rails 1 and 2. In addition, this reloading
One end 6b of the cassette body 4 on the component loading/unloading side is inserted into the groove 13 of the lower rail 2.

By constructing the magazine stopper 21 with a flat plate material of a certain length, it is possible to collect the cassette body 4 (empty cassette body) with one end 6a of the component loading/unloading side of the empty magazine 5 group positioned at a predetermined position. It is preferable that the magazine stopper 21 is made of the above-mentioned material, but if the positioning is to be performed separately after the cassette body is recovered, it may be made of a short material instead of the long material mentioned above.

The mode in which one cassette body 4 is loaded onto both rails 1 and 2 and parts are sent out has been described above, but by loading a plurality of cassette bodies 4, parts can be sent out from the preceding cassette body 4. Therefore, more electronic components can be delivered per unit time without interruption of parts delivery.

Note that the loading of the cassette body 4 onto both rails 1 and 2 can be carried out even when parts are being fed out from the preceding cassette body 4, and the loading of the cassette body 4 onto both rails 1 and 2 can be done automatically after the parts feeding is finished. The running empty cassette body 4 is stopped from moving by a suitable stopper means, and is removed from both rails 1 and 2 by an operator.

[Effects of the Invention] As described above, according to the present invention, parts can be automatically delivered by loading the cassette bodies into which electronic components are to be delivered one after another onto a pair of inclined rails, and moreover, It is possible to send out electronic components from the next cassette without being disturbed by the empty cassette that was sent out, and therefore more electronic components can be sent out per unit time without interrupting the delivery of parts. Thus, an electronic component delivery device is obtained.
