Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic component mounting machine for mounting electronic components such as FICs on printed circuit boards.

2. Description of the Related Art A conventional electronic component mounting machine such as an FIC has a structure as shown in FIG. That is, the pallets 1 shown in FIG. 2, which are often used in the FIC manufacturing process, are stacked and transferred to the pallet transport unit 3 by the transfer robot 2 and positioned at a predetermined position. The FIC is mounted on the printed circuit board 4 which has been transported and positioned at the position, and the mounting robot 5 with printed circuit board recognition sequentially mounts the FIC onto the printed circuit board 4 from inside the pallet 1&, and the empty pant) 1a is transported on the pallet. It is discharged in section 3. When mounting two types of FIC, two mounting robots with recognition are required.

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

This is due to the following reasons.

In other words, since the configuration is a transfer robot 2 that transfers pallet 1 to pallet transport section 3 and a transfer section that can only transport one type of pallet, two or more recognition-equipped mounting robots are required to handle pallets of two or more types. 6 was necessary.

In view of the above problems, the present invention provides an apparatus for mounting two or more types of FICs in a pallet onto a printed circuit board using one electronic component mounting machine.

Means for Solving the Problems In order to solve the above problems, the present invention provides a pallet on which a plurality of electronic components are arranged on a horizontal surface at regular intervals so that they can be easily taken out upwards, and the pallets are arranged vertically at regular pitches. It is provided with a parts supply section that is movable, adjustable in the width direction according to the pallet, and has a carry-out section for carrying out one pallet in a vertical direction.

The present invention has the above-mentioned configuration, and is capable of stacking pallets in multiple stages at a fixed pitch, and as a means for sending the nozzles carried out from the lower stage at a constant pitch. Since it has a pallet feeding claw (part) and pallet feeding claw, it is possible to supply two or more types of pallets with a simple configuration.

Embodiment Below, an electronic component mounting machine according to an embodiment of the present invention will be described 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 at a constant pitch in a chain-type stocker 8, and the pallets 6 and 7 are raised and lowered by a chain 11 via a transmission gear 10 by a drive motor 9, and detected. The lower pallet 6a is stopped at a constant pitch by the container 12, and the lower pallet 6a is moved to the discharge plate 1 by the discharge cylinder 13.
Move 4 to send out a certain amount. Sent out (shi7)
The electronic components 16 in 6a are sequentially suctioned by an electronic component suction unit 17 that is vertically movable on the surface of the xy table 16,
The printed circuit board 19 is mounted on a printed circuit board 19 positioned at a predetermined position of the printed circuit board transport section 18 .

Connect the electronic components in the horizontal row on one side of the pallet to printed circuit board 1.
When the implementation is completed on 9! The side surface 15a into which the electronic components in the pallet 1 are placed is lowered by the pallet feed claw 21 having the drive unit 2o that moves vertically up and down on the surface of the y-table 16.
Hit it! The y-table 16 moves to feed at a fixed pitch, and the electronic component suction unit 17 sequentially suctions the next electronic component on the pallet. The empty pallet falls from the surface of the pallet sliding section 22 onto the pallet ejection conveyor 23 located at the bottom of the printed circuit board transport section 18, and the empty pallet 6b is moved on the pallet ejection conveyor 23 by the conveyor drive motor 24. It falls and is stored in the pallet discharge box 26. 6) Move the pallet onto the pallet sliding part 22 until it reaches the fixed position.
When a is fed by a pitch, the pallet detector 26 is activated, the chain type stocker 8 is lowered by one pitch, and the next pallet 6C containing electronic components is sent out by the ejection cylinder 13 by moving the ejection plate 14 and sending out a fixed amount. By arranging a plurality of chain type stockers 8 containing a certain amount of pallets, it is possible to supply pallets containing a plurality of types. Also, by turning the handle 27 (width adjustment corresponding to change in the width of the let), one side 8b of the chain stocker can be moved along the guide 28. or,
The ejection plate 14 can be adjusted to accommodate changes in the length of the let.

Effects of the Invention As described above, the present invention provides a pallet on which a plurality of electronic components are arranged on a horizontal surface at regular intervals so that they can be easily taken out upwards;
From a parts supply unit, which is capable of storing a plurality of said pallets at a fixed pitch in the vertical direction and moving them at a fixed pitch in the vertical direction, and having an unloading part for carrying out one piece of the pallet from a fixed position in the width direction according to the pallet. The constructed electronic component mounting machine can accommodate multiple types of lefts in multiple stages, and can provide a simple and inexpensive electronic component mounting machine.
