The table 2 is transferred to the upper surfaces of both receiving and transferring bodies 3 and 4, and then the both receiving and transferring bodies 3 and 4 are arranged on the side of the table 2 in a state where the printed circuit board 1 on the upper surface thereof is vacuum-sucked. After horizontally moving to the upper part of the carrier table 5, the receiving transfer bodies 3 and 4 are moved to the printed circuit board 1
In the state where the vacuum suction is released, the printed circuit board 1 is moved from both the receiving transfer bodies 3 and 4 to the transfer table 5 by moving it down or moving the transfer table 5 upward. There is.

[0003]

However, when printing or the like on the printed circuit board 1 on the upper surface of the table 2, the printed circuit board 1 may be cracked into two parts from the substantially central part thereof. If the printed circuit board 1 is cracked in this way, and when the printed circuit board 1 is transferred to the upper surfaces of the receiving transfer bodies 3 and 4 by the downward movement of the table 2, the cracked printed circuit board 1 is shown in FIG.
As shown by the chain double-dashed line, the table 2 and both receiving transfer bodies 3 and 4 are laid across, or the table 2
Since it is placed on the upper surface of the
Will not be removed from the upper surface of the table 2.

Therefore, in the conventional transfer device,
As described above, when the printed circuit board 1 is cracked on the upper surface of the table 2, the movement of both receiving transfer bodies 3 and 4 is stopped, and the broken printed circuit board 1 is removed from the upper surface of the table 2 by the operator. There was a problem that I had to remove it with. The present invention, when a thin plate-like article such as a printed circuit board on the upper surface of a table is cracked, detects the crack and then automatically removes the cracked thin plate-like article from the upper surface of the table. It is a technical issue to provide.

[0005]

In order to achieve this technical object, the present invention provides a pair of left and right receivers provided with a plurality of fingers on the left and right sides of a table which moves up and down with a thin plate-shaped article placed on the top surface. In a transfer device in which the transfer bodies are arranged so as to reciprocate between the table and a carrier table or the like on the side thereof, the thin plate is provided at a portion on the upper surface side of the reception transfer body. While a sensor for detecting cracks in a strip-shaped article is provided, a scraper is placed at a site opposite to the carrier table or the like with a table sandwiched between the scraper and the scraper based on a crack signal of the thin-plate article by the sensor. It is arranged such that it is arranged so as to move along the upper surface of the table in the direction of the carrier along with the movement of the transfer body to the carrier.

[0006]

In this structure, the sensor detects whether or not the thin plate-like article on the upper surface of the table is broken at the time when the thin plate-like article on the upper surface is transferred to both receiving and transferring bodies. It In this case, when the thin plate-shaped article is not broken, only the both receiving and transferring bodies move in the direction of the carrier, etc., and then the thin plate-like article on the upper surface is transferred from the both receiving and transferring bodies to the carrier, etc. Perform the transfer operation.

On the other hand, when the sensor detects cracks in the thin plate-like article, both the receiving and transferring bodies move in the direction of the carrier, etc. By moving the scraper arranged at the portion along the upper surface of the table in the direction such as the carrier table, the broken thin plate-like article can be automatically removed from the upper surface of the table.

Therefore, according to the present invention, it is possible to automatically transfer a thin plate-like article such as a printed circuit board on the upper surface of the table to a carrier table while removing the broken pieces of the thin plate-like article from the upper surface of the table. It has the effect that it can be carried out in a desired manner and the working efficiency can be greatly improved.

The vacuum suction type fingers 13a and 14a are arranged so as to pass through, and a mechanism (not shown) horizontally reciprocates between the table 12 and the carrier table 15 disposed at a side portion thereof. At the location of the carrier table 15, the carrier table 15 is configured to move downward toward the carrier table 15 and then move upward.

By irradiating the printed circuit board 1 on the upper surfaces of the receiving and transferring bodies 13 and 14 with light above the receiving and transferring bodies 13 and 14,
A plurality of sensors 16 for detecting cracks in the printed circuit board 1 are provided, and one of the left and right sides of the table 12 is located on one side and the table 1
A reciprocating head 17 adapted to reciprocate in the same direction as the receiving and transferring bodies 13 and 14 is disposed at a portion opposite to the carrier table 15 with the reciprocating head 1 interposed therebetween.
One end of a scraper 18 is rotatably pivotally attached to the upper surface of 7 by a pin 19, and the scraper 18 is substantially separated from one side surface of the table 12 on the basis of a signal of a printed circuit board crack by each sensor 16. After rotating to a parallel state, the transfer table 1 is moved along with the upper surface of the table 12 along with the movement of the receiving transfer bodies 13 and 14 to the transfer table 15.
It is configured to move in the direction of 5.

In this structure, when the printing or the like on the printed circuit board 1 placed on the upper surface of the table 12 is completed, the table 12 is moved downward, whereby the table 12 is moved.
The printed circuit board 1 on the upper surface of is transferred from the upper surface of the table 12 so as to be placed on the upper surfaces of both receiving transfer bodies 13 and 14. In this case, the transferred printed circuit board 1
However, when it is determined by each sensor 16 that there is no crack, both receiving and transporting bodies 13 and 14 move to a position above the carrier 15 with the fingers 13a and 14a holding the printed circuit board 1 in vacuum. , And the vacuum suction is released to convey the printed circuit board 1 on the upper surfaces of the receiving and transferring bodies 13 and 14 from the receiving and transferring bodies 13 and 14 as indicated by a chain double-dashed line in FIG. Transfer to the table 15.

After the printed circuit board 1 is transferred to the carrier table 15, both receiving and transferring bodies 13 and 14 return to their original positions and repeat the above operation.
The transfer of the printed circuit board 1 from the two receiving transfer bodies 13 and 14 to the carrier 15 is performed by moving the carrier 15 instead of moving the receiving transfer bodies 13 and 14 downward and then moving upward. It may be performed by moving up and then down.
