Description

Description: TECHNICAL FIELD The present invention relates to an electronic component mounter for mounting electronic components such as FICs on a printed circuit board.

2. Description of the Related Art Conventional electronic component mounters such as FICs have the structure shown in FIG. That is, the pallet 1 shown in FIG. 2 which is frequently used in the FIC manufacturing process is transferred to the pallet transfer unit 3 by the stacking transfer robot 2 and placed in a predetermined position from the pallet 1a which is separately specified. The FIC is mounted on the printed circuit board 4 positioned at the position, and the pallet 1a which is emptied is sequentially mounted on the printed circuit board 4 from inside the pallet 1a by the mounting robot 5 with recognition of the printed circuit board. Is discharged at. When mounting two types of FIC, two mounting robots with recognition are required.

Problems to be Solved by the Invention However, the above-mentioned configuration has a problem that the device is large, complicated and expensive.

This is for the following reason.

In other words, the transfer robot 2 that transfers the pallet 1 to the pallet transfer unit 3 and the transfer unit that can transfer only one product type are used. Therefore, in order to support two or more product types, two or more robots with recognition can be mounted. 5 was needed.

In view of the above problems, the present invention provides an apparatus for mounting FICs in two or more types of pallets on a printed circuit board with a single electronic component mounting machine.

Means for Solving the Problems In order to solve the above problems, the present invention provides a pallet in which a plurality of electronic components are easily taken out at a predetermined interval on a horizontal plane, and the pallet is vertically arranged at a constant pitch. It is movable, can be adjusted in the width direction according to the pallet, and is equipped with a component supply unit having a unloading unit for unloading one pallet in a vertical direction.

The present invention has the above-mentioned configuration, and as a means for stacking pallets in multiple stages with constant pitches and feeding the pallets carried out from the lower stage at a constant pitch, an electronic component suction section and a pallet feeding claw that are vertically movable on the xy table. 2 because I have
We have made it possible to supply pallets of various types and more with a simple structure.

Embodiment An electronic component mounting machine according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a plan view of the embodiment of the present invention, and FIG. 4 is a front view thereof. In FIG. 3, pallets 6 and 7 of different types are arranged in a chain type stocker 8 at a constant pitch, and a pallet 6 and 7 are raised and lowered by a chain 11 through a transmission gear 10 by a drive motor 9 to detect the pallets 6 and 7. The container 12 is stopped at a constant pitch and the lower pallet 6a is moved by the discharge cylinder 13 to move the discharge plate 14 to send out a fixed amount. Xy the electronic components 15 in the pallet 6a sent out.
Electronic component suction unit that can move vertically on the table 16
It is sequentially sucked by 17 and mounted on a printed circuit board 19 positioned at a predetermined position of a printed circuit board carry-out section 18. When the electronic components in the horizontal row on the pallet 1 surface are completely mounted on the printed circuit board 19, the electronic components in the pallet 1 are lowered by lowering the pallet feed pawl 21 having the drive unit 20 vertically moving on the xy table 16 surface. The xy table 16 is moved against the side surface 15a where the parts are to be placed, and the xy table 16 is moved at a constant pitch. The pallet that has become empty is located on the lower side of the printed circuit board transport section 18 from the surface of the pallet sliding section 22.
The empty pallet 6b drops on the pallet discharging conveyor 23 by the conveyor drive motor 24 and is stored in the pallet discharging BOX 25. When the pallet 6a is pitch-fed to the fixed position on the pallet sliding portion 22, the pallet detector 26 operates and the chain type stocker 8 descends by one pitch, and the pallet 6c containing the next electronic component is discharged by the discharge cylinder 13. Move the plate 14 and send out a fixed amount. By arranging a plurality of chain type stockers 8 that store a certain amount of such pallets, it is possible to supply pallets that store a plurality of types. Further, one side 8b of the chain stocker can be moved along the guide 28 by turning the width adjusting handle 27 in response to the change of the width of the pallet. Also, the discharge plate 14 can be adjusted to accommodate changes in the length of the pallet.

EFFECTS OF THE INVENTION As described above, the present invention provides a pallet in which a plurality of electronic components are arranged on a horizontal surface at a constant interval so as to be easily taken out upward,
An electronic component configured by a component supply unit that stores a plurality of the pallets in a vertical direction at a fixed pitch, can move a fixed pitch in the vertical direction, and has a carry-out unit that carries out one pallet from a fixed position in the width direction according to the pallet. The mounting machine can store a plurality of types of pallets in multiple stages and can supply a simple and inexpensive electronic component mounting machine.
