【Example】

 An embodiment of the substrate positioning mechanism of the present invention will be described below with reference to the drawings.

FIG. 1 shows a substrate mounting table in the form of a holder in the substrate positioning mechanism of the present invention. 1 is a substrate supporting magnet holder, 2 is a rising board made of a magnetic material, 3 is a substrate mounting table, and 4 is a substrate mounting table. Substrate positioning pins 5 and 6 provided upright on the mounting table 3 are conveyor frames for guiding a substrate sent by a transfer conveyor. One conveyor frame 5 is a fixed reference side, and the other conveyor frame 6 is a reference frame. It is a variable side corresponding to the size of the board.

In the substrate supporting magnet holder 1, the magnet 1b is inserted in the recess of the bottom surface of the holder body 1a, and the screw shaft 1d extending from the lower surface of the substrate mounting table 1c is inserted in the insertion hole provided in the upper surface. The screw shaft 1d is screwed with a mounting table height adjusting portion 1e provided on the upper portion of the holder body 1a.

FIGS. 2 and 3 show a substrate mounting table on which the substrate positioning pins in the substrate positioning mechanism of the present invention are erected. 3 and 3 ′ are substrate mounting tables, which are on the side of the conveyor frame 5 fixed together. One substrate mounting table 3 is a fixed side and the other substrate mounting table 3'is a variable side, and substrate positioning pins 4 and 4'are erected on each side. Further, 8 is a linear guide provided on the ascending board 2, 9 is an elongated hole which is parallel to the linear guide 8, and 10 is a fixed knob which is attached to the substrate mounting table 3'and fixes the mounting table 3 '. is there .

The substrate mounting table 3 ′ has a groove portion 3 a formed in a lower portion thereof so as to be fitted with the linear guide 8 so as to be movable along the linear guide 8 and a fixed knob 10 attached to the substrate mounting table 3 ′. Is loosely inserted into the elongated hole 9 of the rising board 2 and screwed to the nut 10a.

Next, regarding the operation of the substrate positioning mechanism of the present invention, first, the substrate 7 guided by the conveyor frames 5 and 6 and sent by the conveyor is stopped at a predetermined position by a stopper (not shown). . Then, the ascending board 2 attracted by the substrate supporting magnet holder 1 ascends, the substrate positioning pins 4 and 4'engage with engaging holes (not shown) of the substrate 7, and the substrate mounting tables 3, 3'and 1c. The board 7 is placed on the board 7, and the lift board 2 is lifted to a predetermined height to complete the operation.

The substrate supporting magnet holder 1 used here is for positioning and fixing the magnet 1b inserted in the recessed portion on the bottom surface by attracting it to the rising board 2 made of a magnetic material. Even if the dimensions of the holder are changed, the position of the holder 1 can be easily changed.

Is fitted in a linear guide 8 on the ascending board 2 and is movable. Therefore, even if the size of the board 7 to be mounted changes and the position of the engaging hole of the board 7 changes, the board positioning pins 4'can be easily moved to the board 7 by moving the board mounting table 3 '. It can be accurately moved to the position of the engaging hole. Then, by rotating the fixing knob 10, the substrate mounting table 3'can be easily fixed.

Even when the heights of the substrate mounting tables 3, 3 ′ and 1 c are different from each other, by rotating the mounting table height adjusting section 1 e of the holder 1, the substrate supporting magnet holder 1 can be mounted on the substrate. The height of the table 1c can be adjusted.

In this embodiment, only the substrate supporting magnet holder 1 having the function of adjusting the height of the substrate mounting table is shown, but the substrate mounting tables 3 and 3 ′ can also be used with the above function.

In the present embodiment, the case where one substrate mounting table in the form of a holder and two substrate mounting tables in which the substrate positioning pins are erected are used are described as an example. It goes without saying that the present invention can be applied to a case where only a single type of the above two types of substrate mounting bases are used or a case where a plurality of both types are used, depending on the size and weight.
