Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an automatic electronic component mounting device that mounts chip-shaped electronic components supplied by a component supply device onto a printed circuit board.

(Explanation) Prior art As a prior art, the patent application filed in 1986 by the present applicant
- In the specification attached to No. 247913, the cassette positioning hole (also a mounting hole) provided in the tape cassette base (parts supply stand according to the present application) protrudes from the bottom of each cassette (also part supply device e). A technique is disclosed in which the cassette base is attached to the cassette base by inserting a pin (also a support pin).

However, according to this method, the work of changing the cassettes is complicated, and the adjustment of the cassettes is also difficult.

(c) Problems to be Solved by the Invention Accordingly, it is an object to simplify the setup change work.

(2) Means for Solving the Problems Therefore, the present invention provides a linear guide that guides the left and right movement of a component supply device that sequentially supplies chip-shaped electronic components mounted on a printed circuit board through a linear guide bearing. In an electronic component automatic mounting device having a component supply stand on which several component supply device groups are installed, an exchange rail stand provided with another linear guide is arranged in series so as to be in a straight line with the linear guide, The component supply device group is allowed to slide on the linear guide via the linear guide bearing, and is transferred onto the exchange rail table via another linear guide provided in series.

Further, the present invention provides a component in which a desired number of component supply device groups are installed via linear guide bearings on a linear guide that guides the left and right movement of a component supply device that sequentially supplies chip-shaped electronic components mounted on a printed circuit board. In an electronic component automatic mounting device having a supply stand, a main base on which the component supply stand is attached to the linear guide bearing, and a group of component supply devices attached to the main base via attachment fittings are constructed. It is divided into two sub-bases.

(E) Function Therefore, by connecting the linear guide of the exchange rail stand in a straight line with the linear guide of the automatic electronic component mounting device, the component supply device group can be exchanged via the linear guide bearing. It is transferred onto the rail platform.

Furthermore, a sub-base on which a group of component supply devices is mounted is attached to the main base attached to the linear guide bearing via attachment fittings.

(F) Example Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 6.

(1) is a base of an electronic component automatic mounting device for mounting chip-shaped electronic components (not shown) onto a printed circuit board (not shown).

<2) (3) is a pair of conveyors for transporting the substrates.

(4) is a parts supply device (5) on the bottom surface of which the parts will be described later;
This is a rotary disk on which a large number of suction heads (not shown) each having a plurality of suction nozzles (not shown) for picking up and conveying the suction head are intermittently rotated by a rotary disk drive source (not shown).

(6) is a component supply stand on which a large number of the component supply devices (5) are arranged in a row, and the base (1) is connected to the base (1) through a linear guide (7) and a linear guide bearing (8) in the longitudinal direction of the base (1). The support pins (9) and (10) provided at the bottom of the component supply device (5) are installed in a positioning state in the mounting holes (not shown) provided in the component supply table (6). has been done.

11 is a slide mechanism that moves the component supply device (5) by rotation of a ball screw (12) that is rotated by a drive source (not shown).

(13) is a support arm extending from the component supply stand (6), and on this support arm (13) is a table reel attachment plate (1) to which a table reel (14) is attached.
5) The lower end surface portion (15A) is supported in an unfixed state.

(16A) and (16B> are respectively linear guides (7A><7
B> and is equipped with a new parts supply device (5) for replacing the parts supply device (5). It is a stand and an empty replacement rail stand.

The operation will be explained in detail below based on the drawings.

By rotating the ball screw 12》, the desired parts supply device (
5) is allowed to wait at the parts removal position, the parts in the tape stored in the table reel (14) are taken out by the suction nozzle, and the conveyor (2
) It is completely transported onto the board that was transported in step (3), and is mounted at a predetermined position on the board.

Next, to explain the setup change operation of the component supply device (5), as shown in FIG. Install a replacement rail stand (16A) with a new parts supply device (5) on the left side and an empty replacement rail stand (16B>) on the right side, and replace the parts supply stand (6) currently on the linear guide (7) with an empty one. Transfer the parts onto the replacement rail stand (16B), and after the transfer is completed, transfer the new parts supply device (5) onto the linear guide (7) (see 1st).

In addition, FIGS. 7 and 8 show other embodiments in which the parts supply table (6) is divided into a main base (17) and a sub-base (18) to simplify setup changes of the parts supply device (5). I will explain based on this.

Each locate pin (
A desired number of component supply devices (5) can be installed in a positioned state via the sub base (18) via the locate bin (19) provided on the main base (17) provided on the linear guide bearing (8). 20), the component supply device <<5>> is fixed by the sub-base fixing bolt (21), and the linear guide bearing (8)
can be attached to. In other words, by preparing a large number of sub-bases (18) to which the parts supply device (5) is attached, the operator can move the sub-base (18) currently attached to the main base (17) to the fixing port (21). ), the parts supply device (5) can be easily changed by simply loosening and removing the sub-base (18) and fixing a new sub-base (18).

Furthermore, as shown in FIGS. 9 and 10, the base (1) is divided into the electronic component automatic mounting device main body side tampering table (IA) and the component supply device (5) mounting table (IB), and the desired Locate the parts supply device (5) together with its mounting base (IB) using the locate pin (
