DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a board automatic insertion and removal apparatus for use in board inspection apparatus and the like.

[0002]

2. Description of the Related Art In a conventional board substrate apparatus, since a rack is fixed in a furnace, boards are replaced manually.

[0003]

However, in the above-described conventional board inspection apparatus, since the connection between the board and the connector has to be manually performed, the replacement operation cannot be performed until the temperature in the furnace reaches room temperature, and the rack is not connected to the furnace. Because of the internal fixation, it was necessary to change the board to a board carrier, which had the disadvantage of causing a work loss during the test time.

[0004] The present invention has been made to solve such conventional problems, it is this interchanging rack each board remains in a high temperature state, the board and the connector can be automatically and accurately collectively <br/> insertion and removal it is an object to provide a less good board automatic insertion and removal instrumentation <br/> location of work loss.

[0005]

According to the present invention, in order to achieve the above object, a plurality of boards on which electronic components are mounted are stacked.
A rack, a transport unit for transporting the rack,
Multiple connectors that can be freely inserted and removed from each of the boards
And guide pins provided at both ends of the plurality of connectors.
Before positioning the board and the connector.
Mating holes provided in the rack to be fitted with the guide pins
And the drive source makes an arc motion to move the rack,
In this configuration, an arm for inserting and removing the board from the connector is provided .

[0006]

Therefore, according to the present invention, by providing the transport means for transporting the rack on which the boards are loaded, the boards can be taken in and out together with the racks even when the temperature in the furnace is high.

[0007]

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

In FIG. 1, FIG. 2 and FIG. 3, the board 1 is
A printed circuit board on which electronic components are mounted, and a rack 2
Is loaded with a board 1. The transport conveyor 3 transports the rack 2 on which the boards 1 are loaded, and the constant temperature bath 4 has the transport conveyor 3 mounted thereon. Shaft drive system 5
Is installed on the ceiling of the shaft 6 and drives the shaft 6. The arm 7 is connected above and below the shaft 6 and performs an arc movement in conjunction with the shaft 6. Special guide pin 8
The taper angle is small and long so that the clearance between the board 1 and the rack 2 can be positioned with a high accuracy of ± 0.1 mm from a rough state of ± 2 mm. Have been. Connector 9
Are attached to the furnace wall and are connected to the board 1.
The roller clamp 10 is attached to the side surface of the rack 2 and is inserted into a hole of the aluminum bar below the side surface of the board 1 to play a role of preventing the board from being shifted during transportation and from falling. Holes 11 made of aluminum square material, which are fitting holes, are provided at two places on the left and right below the end face for connecting the board 1 and the connector 9, and the special guide pins 8 are inserted into these holes.

Next, the operation of the above embodiment will be described.
When the rack 2 on which the boards 1 are loaded is supplied to the furnace entrance of the constant temperature bath 4, the transport conveyor 3 operates to transport the rack 2 toward the back and stop at a certain position in the furnace. . During the transportation of the board 1, the board 1 is fixed by the roller clamp 10.
Will not fall. A portion of the board 1 slightly protrudes from the rack 2, and the shaft 6 is driven by the shaft drive system 5.
Is activated, and the two arms 7 in front of them push it. The board 1 enters, the special guide pin 8 of the furnace wall fits into the hole 11 of the aluminum square material which is the fitting hole, and the board 1 and the connector 9 are connected.
Is connected. At this time, even if the connection is not established, since the slip function is provided in the shaft drive system 5, the board 1
And to prevent the connector 9 from being damaged. An inspection is performed to apply heat and electric stress to the board 1 to remove a printed circuit board that may have an initial failure. When the inspection is completed, the shaft 6 is driven by the shaft drive system 5 and the two back arms 7
However, the part of the board 1 that is slightly deeper than the rack 2 is pushed. The board 1 is simultaneously pulled out of the connector 9, the rack 2 is transported by the transport conveyor 3, and taken out of the thermostat 4.

As described above, according to the above embodiment, since the conveyor 3 transports the rack 2 on which the boards 1 are loaded, the boards 1 can be taken in and out together with the racks 2 even when the temperature in the furnace is high. . Further, by providing the special guide pin 8, accurately perform the positioning of the board 1 and the connector 9, since the automatic collective insertion and removal, it is possible to reduce the work loss.

[0011]

As described above, according to the present invention, by providing a rack on which a large number of boards are loaded, the board can be taken in and out together with the rack even when the temperature in the furnace is high. By providing a special guide pin, since the boards and connectors batch insertion and removal of the allows precise, those that can achieve excellent board automatic insertion and removal device it is possible to improve the work efficiency.
