DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic component mounting apparatus used for suctioning electronic components and mounting them on a circuit board.

[Prior Art] Conventionally, as an electronic component mounting device for mounting electronic components onto a circuit board, a plurality of component supply units containing a large number of electronic components are arranged in parallel and installed on a movable table. By configuring the supply units to be movable in the parallel direction, it is possible to take out the electronic components stored in any component supply unit at a predetermined position, and on the other hand, the position where the electronic components of the circuit board are to be mounted is at the predetermined position. As shown in the figure, it is a good product to have a means for positioning the supplied circuit board, and a component mounting means for holding the electronic component at the predetermined component removal position and mounting the component at a predetermined position on the positioned circuit board. (Are known.

[Problems to be Solved by the Invention] However, the above-mentioned component supply unit can only supply electronic components that are aligned and housed at a certain pitch within a carrier tape. Since the number of electronic components that can be stored in a stick is limited, it is often necessary to replace the stick manually, which reduces the operating rate of the device.

Further, there was a similar problem in that the number of electronic components arranged in matrix on the tray was limited. Furthermore, because they are arranged in a matrix, it is possible to easily supply electronic components that are arranged parallel to the parallel direction, but it is necessary to provide a separate drive means for components that are arranged vertically. There were also challenges.

In order to solve the problems of the prior art, the present invention provides an electronic component mounting device that can stably supply electronic components stored in a stick or electronic components arranged in a strix on a tray for a long time. The purpose is to provide.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration. That is, the electronic component mounting apparatus of the present invention includes a fixed component supply section installed in parallel with the component supply section, a plurality of component supply units installed on the fixed component supply section, and a plurality of component supply units installed on the movable table from the component supply unit. The present invention is characterized in that it includes a transfer means for transferring a component onto the positioning jig, which is movable in parallel with the moving table.

[Function] According to the configuration of the present invention, there is a fixed component supply section installed in parallel with the component supply section, and a plurality of component supply units are installed on the fixed component supply section. Since the transfer means for transferring the components to the provided positioning jig is provided so as to be movable in parallel with the moving table, even electronic components that are not aligned or housed at a constant pitch within the carrier tape can be supplied. Furthermore, even electronic components housed in a stick or electronic components arranged in a strix on a tray can be stably supplied for a long time.

[Embodiment] Hereinafter, an electronic component mounting apparatus shown as an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram of an electronic component mounting apparatus showing a first embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a component supply section, which fixes and holds a component supply unit 2 and can be driven to position it so as to supply a predetermined component. 3 is the head. A component suction nozzle 4 that performs intermittent rotational movement is rotatably and movably attached to the periphery of the head 3. 5 is a circuit board, which is supported by an X-Y table 6. 7 is an electronic component, and 8 is an attitude regulating device for regulating the attitude of the electronic component 7.

The operation of the electronic component mounting apparatus configured as described above will be described below.

First, the suction nozzle 4, which has suctioned the electronic component 7 from the component supply section 1, moves to the mounting position by the intermittent rotational movement of the head 3. During this movement, the posture adjustment device 8 determines the posture of the electronic component 7, and the X-Y table 6 positions the circuit board 5 so that a predetermined position matches the mounting position.Then, the suction nozzle 4 descends, and the circuit board 5 is positioned. Electronic components 7 on board 4
Attach.

FIG. 2 shows a detailed view of the component supply unit 9.

A carrier tape (not shown) on which electronic components 7 (FIG. 1) are arranged and housed at a constant pitch is set in the component supply unit 9. Component supply unit 8 shown in FIG. 1 above
In addition to the component supply unit 9, the electronic components are positioned,
A plurality of jigs (not shown) that can be clamped are provided at arbitrary positions.

Next, the parts supply section is shown in FIGS. 3 and 4.

In FIG. 3, 9 is a fixed parts supply section, and 10 is
This is a transfer unit that transfers the electronic component 7 from the fixed component supply section 9 onto a positioning jig (not shown) on the component supply section 8. On the fixed parts supply unit 9, there is a stick supply unit as shown in FIG. 4(a) or a matrix tray as shown in FIG. 4(b), for example, a QFP.
(4-way flat package IC) A supply unit is fixed and held at an arbitrary position.

In FIG. 3(a), the operation of which will be described below, arbitrary electronic components 7 are sequentially selected from the component supply unit 8 holding a plurality of component supply units 9, and the components are supplied. Meanwhile, transfer unit 10
selects an arbitrary component from the stick supply unit 11 or QFP supply unit 12 held on the fixed component supply section, and sucks and holds it.

At a certain timing, as shown in FIG. 3(b), the component supply unit 1 moves a positioning jig (not shown) so that it is on the same straight line as the electronic component 7 sucked and held by the transfer unit 10. Position. After the positioning is completed, the transfer unit 1.0 transfers the electronic component 7 onto the positioning jig. The transfer unit 10 is movable on the fixed component supply section 9 in a direction parallel to the component supply section 1, and is equipped with a driving means that can transfer from any supply unit to any positioning jig. , it becomes possible to supply a plurality of electronic components 7 to the component supply section. After the transfer is completed, the parts supply unit 1
