Abstract

PURPOSE:To identify transfer heads at a glance and instantly by providing head identification marks where the direction changes along a rotary head consecutively to each of the transfer heads with nozzles for picking up electronic parts. CONSTITUTION:A plurality of transfer heads H1-H12 with nozzles for picking up electronic parts are driven by a driving means U and are subjected to an index rotation along a rotary head R. A nozzle N of each transfer head receives electronic parts P from a part feeder F at a pick-up position Q, is subjected to index rotation while sucking the electronic parts P, and moves to the side of a printed circuit board 0. At this time, head identification marks M1-M12 with arrows D1-D12 in the shape of clock hands which indicate different directions are provided at the transfer heads H1-H12. The arrows have a same angle difference and continue in steps consecutively, thus identifying the transfer heads at a glance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component mounting apparatus, and more particularly to an electronic component mounting apparatus capable of identifying a transfer head at a glance.

[0002]

2. Description of the Related Art As a high-speed electronic component mounting apparatus capable of mounting electronic components such as ICs, LSIs and capacitor chips on a substrate several times per second, one having a rotary head is widely used.

In such an electronic component mounting apparatus, several to several tens of transfer heads are provided, and these transfer heads are rotated along the rotary head,
Electronic components are being mounted. here,
Of the plurality of transfer heads, only a specific transfer head may exhibit a defect such as a pickup error or noise. In such a case, the operator must first identify which of the plurality of transfer heads is causing the problem in order to perform maintenance of the transfer head. This requires that each of the plurality of transfer heads be distinguishable from other transfer heads.

[0004]

In the conventional means, these transfer heads are provided with "1", "2",
Characters such as "3", ... Or "A", "B", "C", ... Are attached so that each head can be identified by this character.

However, in order to further increase the mounting speed of electronic parts, the speed at which the transfer head rotationally moves is increasing, and even if the transfer head is identified by the above characters. It was difficult for the operator to even read it. Therefore, even if there is a transfer head that causes the above-mentioned problem, there is a problem that the transfer head that causes this problem cannot be specified.

Therefore, it is an object of the present invention to provide means for distinguishing transfer heads at a glance.

[0007]

According to the present invention, each of the plurality of transfer heads is provided with a head identification mark whose direction changes sequentially along the rotary head.

[0008]

According to the above construction, the operator need only pay attention to the direction indicated by the head identification mark, and the transfer head can be specified depending on this direction. Therefore, the operator does not need to recognize what the character is like the conventional means, and can sufficiently identify even if the rotational movement speed of the transfer head becomes high.

[0009]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view of an electronic component mounting apparatus according to this embodiment, and FIG. 2 is an illustration of a head identification mark.

In FIG. 1, R is a rotary head, and H is
Reference numerals 1 to H12 denote transfer heads that rotate in an index along the rotary head R, each of which has a nozzle N for picking up and picking up an electronic component P at the bottom thereof. U is a drive means for rotating the transfer heads H1 to H12.

Further, F is a parts feeder such as a tape feeder and a tube feeder which are arranged in parallel behind the rotary head R, and the parts feeder F supplies the electronic parts P to the nozzle N at the pickup position Q. O is a substrate, L is a land formed on the surface of the substrate O, XT and YT are X tables and Y tables for positioning the substrate O, and MX and MY are these tables XT and
This is a YT drive motor.

Now, the transfer heads H1 to H12 are provided with head identification marks M1 to M12 having clock-like needle-shaped arrows D1 to D12 indicating different directions. This arrow
When D1 is zero and D2 is one, they have the same angular difference and are continuous stepwise. Of course, the direction of the rod-shaped mark may be sequentially changed instead of the illustrated arrow, and various modifications can be considered.

This embodiment has the above-mentioned structure, and its operation will be described below. The plurality of transfer heads H1, ...
It is driven by the driving unit U and rotates in the index direction along the rotary head R. Then, the nozzle N of each transfer head
At the pick-up position Q, the electronic component P is supplied from the part feeder F, the electronic component P is sucked, and the index rotation is performed to move to the substrate O side. On the other hand, X
The Y table XT, YT is driven, and the land L of the substrate O is
However, in cooperation with the movement of the nozzle N, the electronic component P is mounted on this land L, and this transfer head is again mounted on the parts feeder F.
Rotate to the side.

The operator OP, which monitors this, marks M1 to M12 attached to the transfer heads H1 to H12, respectively.
To observe. Then, the arrows D1 to D12 are observed just as if the hands of the clock were rotating on the dial, and the operator OP can instantly grasp which direction the arrow currently being observed is facing. Then, the transfer head exhibiting a defect such as a pickup error or noise can be easily identified by using the arrow.

[0016]

According to the present invention, since each of the plurality of transfer heads is provided with the head identification mark whose direction is sequentially changed along the rotary head, the moving speed of the transfer head becomes high. However, the operator OP can easily identify the problematic head depending on the direction of the mark.
