BACKGROUND OF THE INVENTION The present invention relates to a chip-shaped circuit part for taking out a chip-shaped circuit part from a container storing the chip-shaped circuit part in a bulk into a part discharge pipe and sending it out to a plurality of parts conveying paths. It relates to improvement of a supply device.

[0002]

2. Description of the Related Art Conventionally, in order to mount a chip-shaped electronic circuit component at a predetermined position on a circuit board, the supply of the chip-shaped circuit component has been performed using an automatic mounting device as follows. That is, in FIG. 20, a chip-shaped circuit component a housed in a bulk in a container 1 called a hopper
Are taken out one by one, supplied to a plurality of distribution tubes 3, 3 provided in the distributor 2, sent to storage recesses 5, 5... Formed at predetermined positions of the template 4, and received there. The storage recesses 5, 5,... Are arranged in accordance with the positions at which the respective chip-shaped electronic components a are mounted on the circuit board 6, and the template 4 is moved while maintaining the relative position when housed therein. . Thereafter, the chip-shaped circuit component a is moved onto the circuit board 6 by the suction head 8 having the suction nozzles 7, 7,... Complete. Thereby, each of the chip-shaped circuit components a
Are mounted at predetermined positions on the circuit board, respectively. An adhesive or the like is applied to the circuit board 6 at a position where the chip-shaped circuit component a is to be mounted, and soldering is performed while the mounted circuit component a is temporarily fixed with the adhesive. .

In the chip-type circuit component supply device used in such a conventional apparatus, a funnel-shaped gradient is formed on the bottom surface of the hopper 1 in which the chip-type circuit components a are stored in a bulk shape. Through the through hole, the hopper 1
A component discharge pipe 9 slidably inserted in the inside is protrudingly provided. The upper end of the component discharge pipe 9 is opened obliquely, and the hopper 1 is slidably fitted in a concave portion of a guide member fixed to a frame (not shown). As a result, the hopper 1 is slidably guided up and down.
A vertical drive mechanism (not shown) is connected to an arm protruding from the upper end of the hopper 1 via, for example, a bracket, and the hopper 1 is vertically reciprocated by power transmitted from a drive source such as a motor via a transmission mechanism. Is done.

When the hopper 1 is driven up and down in this way, the upper end of the component discharge pipe 9 reciprocates up and down relatively in the hopper 1. When the upper end of the component discharge pipe 9 rises from the bottom of the hopper 1, the chip-shaped circuit component a is broken. When the upper end of the component discharge pipe 9 is lowered, the chip-shaped circuit component a is removed from the opening at the tip. Each of the chip-shaped circuit components a that have entered the component discharge pipe 9 in this manner is taken out one by one and sent downward.

Thereafter, the chip-shaped electronic component a sent into the component discharge pipe 9 protruding from the bottom of the hopper 1 is actuated by the separating slider 10 provided at the lower end thereof.
Drops are supplied to drop holes 12 formed on the surface of the distribution supply unit 11. That is, the slider 10 moves back and forth as indicated by the arrow in the figure, and when the position matches the position of the drop hole 12, the downstream distribution tube 3,
3 is supplied with the chip-shaped circuit component a.

That is, when the position of the through hole 13 at the center of the slider 10 and the position of the drop holes 12, 12 of the distribution / supply unit 11 are shifted, the chip-shaped circuit component a is
When the slider 10 moves in the direction of the arrow and the position of the through hole 13 matches the position of the drop hole 12 of the component supply unit 11, the chip-shaped circuit component a Are conveyed and supplied into the distribution tubes 3, 3 through the drop holes 12.

[0007]

However, in the above prior art, the slider is slidably disposed between the lower end of the component discharge pipe and the slider base on the surface of the distribution and supply section. However, the slider can only move in one direction.
That is, the number of circuit components a that can be supplied from one component supply device (that is, from one hopper) (that is, the number of distribution tubes that can supply the circuit component a in parallel) is 2 at a maximum. Only one can be supplied.

As described above, the above-described conventional component supply device can supply only up to two circuit components at the same time. Therefore, when two or more identical circuit components are mounted on a circuit board, Despite being the same type of circuit components, it is necessary to arrange a plurality of supply devices for supplying the same circuit components. In this case, in order to automatically supply a necessary number of types of components necessary for a circuit board to be mounted, the number of necessary component supply devices increases and the component supply device as a whole becomes large. . Further, even though the circuit components to be supplied to the hoppers of the respective component supply devices are the same circuit components, it is necessary to supply the same to a plurality of supply devices, which causes a problem that so-called maintenance work becomes complicated. I was

In view of the above problems in the prior art, the present invention freely takes out and supplies a desired number of circuit components from one to three or more from one container (hopper). It is an object of the present invention to provide an improved chip-shaped circuit component supply device capable of performing the above-mentioned operations.

[0010]

A component discharge pipe inserted into the component discharge pipe, a distribution / supply unit disposed below the component discharge pipe, and formed with a plurality of component drop holes at a surface position different from the disposition position of the component discharge pipe; A slider disposed between the lower end and the surface of the distribution supply unit, the slider moving on the surface of the distribution supply unit, and the movement of the slider sequentially causes the chip-shaped circuit components to be discharged from the component discharge pipe. In the one that supplies the chip-shaped circuit component while dropping into the plurality of component drop holes, three or more component drop holes formed on the surface of the distribution supply unit are planarly arranged, A slider moving device for moving the slider includes a pusher for moving the slider in a predetermined direction on the plane, and moving the slider in a direction perpendicular to the predetermined direction on the plane. The present invention is achieved by a chip-shaped circuit component supply device including a side pusher for moving.

According to the invention, the side pusher has a groove for inserting an end of the slider.
A chip-shaped circuit component supply device has been devised which is formed by a plurality of grooves having different widths, or provided with a stopper pin near the pusher for restricting the movement of the pusher.

[0012]

In other words, according to the above-described chip-type circuit component supply device of the present invention, three or more component drop holes formed on the surface of the distribution supply section are arranged in a plane, and the slider is moved. The slider moving means for, in addition to a pusher for linearly moving the slider in a predetermined direction, a side pusher for moving the slider in a direction perpendicular to the predetermined direction, The slider can be freely moved on a plane. This makes it possible to drop and supply three or more circuit components to the component drop holes arranged on the plane, and it is possible to simultaneously supply three or more circuit components of the same type.

Further, the groove shape of the side pusher described above,
Alternatively, a stopper pin limits the movement range of the slider on a plane, so that a desired number of circuit components can be taken out and supplied simultaneously to the downstream side despite the three or more component drop holes. become.
