Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for replacing a chip component storage pack containing a small chip component without lead wires.

[0002]

2. Description of the Related Art The applicant of the present invention discloses in Japanese Patent Application No. 1-140994 that a chip part storage pack is formed in which a storage path that continuously circulates is formed inside a case, and chip parts are stored in the storage path. Disc pack) is proposed. This chip parts storage pack integrates completely different functions of packing and supply of parts, and can store chip parts in the storage path inside the case in an aligned state, and by sending compressed air to the storage path. The chip components can be aligned and ejected from the component delivery port at the end of the storage path.

[0003]

By the way, conventionally, in a chip component supply unit of a chip component mounting machine using a chip component storage pack, replacement when the chip component storage pack becomes empty depends on manual work. It was However, in order to realize continuous operation of the chip component mounting machine for mounting the chip components on the printed circuit board, it has been demanded that the chip component storage pack of the chip component supply unit can be automatically replaced.

In view of the above points, the present invention is equipped with a chip component storage pack in which a new chip component is filled in a chip component supply section using the chip component storage pack by utilizing the vertical movement of the chip component storage pack. An object of the present invention is to provide a method and an apparatus for replacing a chip component storage pack that is possible.

[0005]

In order to achieve the above object, a method of exchanging a chip component storage pack according to the present invention is such that an empty chip component storage pack is detached from a chip component supply section equipped with the chip component storage pack detachably. Drop or drop
A new chip component storage pack is arranged above the chip component supply unit and detachably stores the chip component storage pack, and a new chip component storage pack is dropped to the chip component supply unit.

Further, in the chip component storing pack exchanging device according to the present invention, a storing magazine for detachably storing the chip component storing pack is arranged above the chip component supplying portion for detachably mounting the chip component storing pack. An arrangement is provided in which the chip component storage pack in the storage magazine is moved down and moved to the chip component supply unit to move up and down.

[0007]

According to the present invention, the empty chip component storage pack in the chip component supply unit is discharged by dropping or dropping from the chip component supply unit, and a new chip component storage pack filled with chip components is stored in the storage magazine. It is possible to equip the chip component supply unit by lowering it to the supply unit. In this way, by moving the chip component storage pack from the top to the bottom, the chip component storage pack can be refilled reasonably and quickly. As a result, chip components can be continuously supplied from the chip component supply unit, and the chip component mounting machine can be continuously operated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a method and apparatus for replacing a chip component storage pack according to the present invention will be described below with reference to the drawings.

In FIGS. 1 to 5, reference numeral 1 denotes a chip component supply section of the chip component mounting machine, which has a compartment 2 for mounting a plurality of chip component storage packs DP. Each compartment 2 is provided with a bellowram or the like that expands when compressed air is introduced and contracts when compressed air is exhausted, so that the chip component storage pack DP can be detachably arranged. Also,
An opening / closing support member 3 that supports the chip component storage pack DP so as to drop or descend is provided at the bottom of each compartment 2. The open / close support member 3 is driven by a cylinder or the like from a horizontal state (chip component storage pack support state) to a vertical state (chip component storage pack release state).
Such a chip component supply unit 1 is fixed to, for example, a chip component mounting machine 20 for mounting a chip component on a printed circuit board.

On the other hand, the storage magazine 10 arranged in parallel above the chip component supply unit 1 at a predetermined interval is provided with compartments 11 for detachably accommodating the chip component storage pack DP, and each compartment 11 has a compartment 11 therein. Is provided with a chip part storage pack DP filled with new chip parts. Here, an opening / closing support member 12 that supports the chip component storage pack DP so as to be dropped or lowered is provided at the bottom of each compartment 11, and the opening / closing support member 12 is in a horizontal state (chip component storage pack support It is designed to be driven from the state) to the vertical state (chip component storage pack released state). This storage magazine 10 is a chip component mounting machine 20.
Is attached via a lateral slider 21.
In other words, it is movable relative to the chip component supply unit 1 in the horizontal direction.

As shown in FIG. 5, an up-and-down transfer robot 30 is installed as an up-and-down transfer changing means for transferring the chip component storage pack DP from the storage magazine 10 to the chip component supply unit 1. The lower end 30 has a chuck 31 capable of holding the chip component storage pack DP. The robot 30 moves a horizontal position along the longitudinal direction (perpendicular to the paper surface of FIG. 1) of the chip component supply unit 1 so that the chip component storage pack DP can be transferred to all the compartments 2 of the chip component supply unit 1. It can be changed.

The tray 35 for the empty chip component storage pack is arranged below the chip component supply unit 1.

When the chip component storage pack DP in the compartment 2 in which the chip component supply unit 1 is present is empty, the open / close support member 3 of the compartment 2 in which the empty chip component storage pack DP is located is as shown in FIG. It is opened vertically to release the empty chip component storage pack DP, and the chip component storage pack DP is dropped onto the tray 35 by its own weight. After that, as shown in FIG. 5, the new chip component storage pack DP in the storage magazine-side compartment 11 located right above the empty compartment 2 is held (sandwiched) by the chuck 31 of the vertical transport robot 30, The opening / closing support member 12 of 11 is opened vertically, and a new chip component storage pack D
P is lowered and placed on the open / close support member 3 of the section 2 on the chip component supply section side that has returned to the horizontal state. After that, the new chip component storage pack DP is fixedly supported on the section 2 side by the action of the bellows or the like, and the chip components are supplied from the new chip component storage pack DP to the chip component mounting machine 20.

If there is no new chip component storage pack DP corresponding to the storage magazine side compartment 11 located right above the empty chip component supply section side compartment 2, the corresponding new chip component storage pack DP is not present. It suffices to move the storage magazine 10 until the section 11 in which the DP is present is directly above, and then execute the operation of the vertical transport robot 30 shown in FIG.

In the above-described embodiment, the empty chip component storage pack DP is discharged from the chip component supply unit 1 by dropping it by its own weight, but the vertical transfer robot is also used for discharging the empty chip component storage pack DP. The component storage pack DP may be chucked and lowered to the tray.
The vacancy of each section 2, 11 can be confirmed by a sensor.

[0016]

As described above, according to the present invention,
By moving the chip component storage pack up and down with respect to the chip component supply unit that uses the chip component storage pack, a new chip component storage pack can be rationally and quickly replenished, and the chip components are continued from the chip component supply unit. Can be supplied as a result, which in turn enables continuous operation of the chip component mounting machine.
