Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component supply device for supplying electronic components to an electronic component mounting device for mounting electronic components on a printed circuit board.

[0002]

2. Description of the Related Art In recent years, in order to cope with the complication of printed circuit boards and the diversification of products, an electronic component mounting apparatus has been required to efficiently produce many kinds of electronic components with one mounting. ing.

A conventional electronic component mounting apparatus will be described below with reference to FIG. As shown in the figure, a head portion 22 for picking up electronic components and mounting them on the printed circuit board 21.
On the other hand, a component supply table 26 which is reciprocally linearly moved and positioned by the servo motor 23, the ball screw 24, and the linear guide 25 is arranged.

The parts supply table 26 has
A plurality of parts feeders 27 that feed out taped electronic parts at a constant pitch can be mounted.

When the component mounting apparatus is operated in the above configuration, the electronic component is taken out from a certain position and the head unit 2
For 2, the necessary electronic components were sequentially moved and positioned by the component supply table 26 and supplied, and mounted on the printed circuit board 21.

Also, there are various sizes of electronic parts, and several kinds of parts feeders 27 defined by JIS or the like had to be arranged on the same parts supply table 26.

[0007]

In the structure of such a conventional electronic component mounting apparatus, the part feeder 2 corresponding to one taping size in the component supply table 26 is provided.
Since 7 are arranged at the constant pitch A, the parts feeder 28 corresponding to the taping having a size larger than the taping cannot be arranged at the constant pitch A, and therefore the parts feeder 28 is arranged at a position twice or three times the constant pitch A. Will be done.

As a result, the types of electronic components that can be mounted on the component supply table 26 are reduced. Further, in order to sequentially take out different kinds of electronic parts, there is a problem that the moving distance of the parts supply table 26 becomes long and the productivity is lowered.

The present invention solves the above problems, and an object of the present invention is to provide an electronic component supply device in an electronic component mounting device in which several types of taping can be arranged efficiently.

[0010]

The electronic component supplying apparatus of the present invention is for connecting a component feeder for feeding an electronic component tape for supplying an electronic component to an electronic component mounting apparatus at a constant pitch, and for connecting this part feeder to a component supply table. A positioning pin provided on the parts feeder and a mounting hole provided on the parts supply table so that the positioning pin engages, and the pitch of the mounting holes is arranged at a pitch narrower than the width of the parts feeder. .

[0011]

According to the present invention, the pitch of adjacent mounting holes is narrower than the standard part feeder even when a larger part feeder than the standard part feeder is mounted depending on the type of electronic parts. Mounting can be done at intervals that are narrower than multiples of the standard parts feeder mounting interval, the types of electronic components that can be mounted are expanded, and the movement distance of the component supply table can be shortened, so the mounting time per electronic component can be reduced. It can be shortened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
Will be described with reference to. As shown in the drawing, a positioning pin 3 for positioning the electronic component tape for supplying an electronic component to an electronic component mounting device (not shown) is attached to a component supply table 2 at a lower portion of a part feeder 1 that feeds the electronic component at a constant pitch. And mounting holes 4 with which the positioning pins 3 of the parts feeder 1 engage are provided at a plurality of intervals on the side of the parts supply table 2.

Then, the mounting holes 4 adjacent to the mounting holes 4
The mounting holes 4 are arranged with a pitch of 1/2, which is the distance between the reference width dimension b of the part feeder 1 and the gap between the part feeders 1.

With the above-described structure, when supplying the same type of electronic components, as shown in FIG. 2, one is attached to the mounting hole 4 of the component supply table 2 with which the positioning pin 3 of the reference parts feeder 1 engages. The positioning pin 3 of the next parts feeder 1 is engaged and attached to the mounting hole 4 which is skipped.

That is, since the pitch of the mounting holes 4 provided in the component supply table 2 is 1/2 of the mounting pitch c of the parts feeder 1, the positioning pins 3 are engaged with the mounting holes 4 one by one. As a result, the parts feeder 1 is moved to the parts supply table 2 at a predetermined mounting pitch c.
Can be set to.

Further, as shown in FIG. 3, when the parts feeder 1a having a width (for example, twice as large) as the width of the reference parts feeder 1 is set beside the reference parts feeder 1, the reference parts feeder 1 is set. Positioning pin 3
Can be set by engaging the positioning pins 3a of the parts feeder 1a to the mounting holes 4 provided in the component supply table 2 which are engaged with the mounting holes 4 provided at intervals of two.

At this time, a large pitch interval d of the parts feeder 1a with respect to the reference parts feeder 1 is obtained.
Is 1/2 of the mounting pitch c of the parts feeder 1 with the pitch of the mounting holes 4 provided in the parts supply table 2 as a reference.
Since it is provided at a pitch of 1, the mounting pitch c of the standard parts feeder 1 is 1.5 times,
When the mounting holes 4 are provided at intervals of the mounting pitch c of the standard parts feeder 1 and a large parts feeder 1a is mounted, the mounting holes 4 are narrower than the case where the mounting pitch is only twice the mounting pitch c. The parts feeders 1 and 1a can be arranged on the parts supply table 2 at intervals.

[0018]

As is apparent from the above embodiments, according to the present invention, the mounting holes for engaging the positioning pins provided in the parts feeder are provided on the parts supply table at a pitch interval narrower than the width of the parts feeder. Therefore, when a large number of parts feeders are set, it is possible to narrow the set interval of the parts feeder, shorten the moving distance of the parts supply table, and provide an electronic parts supply device that can efficiently supply electronic parts. .
